Description

 Interaction method between user equipment and location service system when user initiates operation TECHNICAL FIELD

 The present invention relates to the positioning technology of network equipment, and particularly to an interaction method between a user equipment and a location service system when a user initiates an operation. Background of the invention

 The location service (LCS, Location Service) of a mobile communication network obtains location information of a target user equipment (UE) through positioning technology. The target UE refers to a device terminal located in a mobile communication network. The location information may be geographic latitude and longitude information or local Location information of the street. The location information obtained by the mobile communication network can be provided to the target UE for its own positioning; it can also be provided to the communication network itself for subregional charging or operation and maintenance; it can also be provided to other requests for the location information of the target UE Of client applications, such as institutions and individuals, are used for value-added services. Therefore, location services have a wide range of functions in emergency rescue, vehicle navigation and intelligent transportation systems, work scheduling and team management, mobile yellow page query, and enhanced network performance. In the 3rd Generation Partnership Project (3GPP), the LCS specification and the functional mode, structure, status description, and message flow of the entire location service are described.

FIG. 1 is a schematic diagram of a logical structure of a network including an LCS system. As shown in FIG. 1, the requester 101 requests the location information of the target UE 103 through the LCS system 102, and the LCS system 102 performs legality authentication on the requester 101 and checks the target UE 103. Whether to provide the location information of the target UE to the requester 101. If the requester 101 is authenticated by the LCS system 102, the LCS system 102 provides the location information of the target UE 103 to the requester 101; otherwise, the LCS system 102 refuses to request The terminal 101 provides location information of the target UE 103. The requester 101 may include a requester and an LCS client. LCS client is used to obtain one or more The software or hardware entity that interfaces with the LCS system 102 for the location information of the target UE 103. The requester refers to the application client, such as an institution or an individual, that requests the location information of the target UE 103, and is the initiator of the location request. The LCS client also Can be a requester at the same time.

 At present, in the 3GPP LCS standard, the location information request initiated by the requester to the target UE is divided into two types: immediate location information request and delayed location information request. Immediate location information request means that the LCS system immediately locates the target UE after receiving the location information request from the requesting end to the target UE, and then immediately returns the positioning result of the target UE to the requesting end, that is, the LCS system receives the After the location information is requested, the positioning result of the target UE is immediately returned to the requesting end. Delayed location information request refers to the requesting end requesting the LCS system to provide the location information of the target UE to it at a future point in time or when a certain event occurs. That is, after the LCS system receives the location information request from the requesting end to the target UE, it needs to go through After a delay, wait for the delay event to trigger before returning the positioning result of the target UE to the requester.

 In addition, 3GPP allows the requester to request the LCS system to provide it with the location information of the target UE periodically, that is, the requester defines the start time point and the end time point and a certain periodic logic, and requires the LCS system to follow the periodic logic to the It provides the location information of the target UE. In addition, the periodic location information request and the delayed location information request can be combined with each other, that is, the requester can send the periodic delayed location information request to the LCS system.

Since the location information is private information of the user to the target UE, its location information should be strictly protected. For any requesting end requesting the location information of the target UE, the LCS system needs to perform legitimacy authentication. According to the preset setting of the target UE in the LCS system or the LCS system sending the requesting end information to the target UE for direct authentication, check Whether the target UE authorizes the requester to request its location information. Even if a requester has passed the legality authentication of the LCS system and initiated a location information request for the target UE, the LCS system must allow the target UE to query the active location information request currently initiated for it, and Cancel these location requests.

 It is proposed in the 3GPP LCS specification to allow the target UE to query or cancel the valid location information request that is currently activated at any time. The activation status of the location information request refers to the status of the location information request from the start time of the location information request and sent to the LCS system to the end time of the LCS system execution. However, the specific implementation process for the target UE to query or cancel the effective location information request of the current activation status at any time is not specified in 3GPP, that is, how the target UE and the LCS system perform information interaction, so that the query or cancellation operation is implemented in 3GPP. No related definitions. Therefore, the target UE does not know how to perform the query or cancel operation, and how to notify the LCS system of its desired operation. The LCS system also does not know how to perform the query and cancel operations on all the location information requests that are currently activated, and how to The result of the operation is notified to the target UE.

 In addition, if the target UE can only query and cancel the location information request that is currently activated, it cannot be achieved. The target UE needs to query or cancel some location information requests under specific conditions, which cannot meet the user's requirements. Multiple needs. Summary of the Invention

 In view of this, an object of the present invention is to provide an interaction method between a user equipment and a location service system when a user initiates an operation, so that the interaction operation between the target UE and the LCS system is implementable, and provide a variety of enhancements that meet user needs. Operation and improve the interactive implementation process of enhanced operation between the target UE and the LCS system.

In order to achieve the above object, the present invention provides a method for interaction between a user equipment and a location service system when a user initiates an operation. The method includes the following steps: A. The user equipment sends an operation request carrying the user equipment identifier to the LCS system, and the LCS The system receives an operation request, searches for a location information request that meets the requirements according to the user equipment identifier, and performs an operation on the location information request according to the current operation request; B. After the operation is completed, the LCS system sends a request to the user The device returned an operation response.

 Before step A, the method further includes: the user equipment sets an enhancement condition for the current enhanced operation; then the step A is: the user equipment sends an enhanced operation request carrying the user equipment identifier to the LCS system, and the LCS system receives the enhanced operation request according to The user equipment identification, searching for a location information request that meets the enhanced condition, and performing an enhanced operation on the location information request according to a current enhanced operation request; the step B is: after the enhanced operation is completed, the LCS system sends to the user equipment Enhanced operational response.

 The invention provides multiple types of information interaction methods, such as general query and cancellation of location information request, modification operation of location information request, activation and deactivation of location information request, etc., and defines the target UE and LCS in the location information request operation. The information interaction process between the systems makes the location information request operation feasible. In addition, the target UE may also set the enhancement conditions of the enhancement operation currently initiated, and the LCS system searches for the location information request that meets the enhancement conditions, and executes the corresponding enhancement operation according to the search result. In addition, the present invention proposes multiple types of location information request operation processes, which can meet different needs of users and enhance the flexibility of user operations.

 The present invention is described in detail below with reference to the drawings.

 The present invention relates to various operations between a target UE and an LCS system, such as a location information request ordinary query operation, a location information request ordinary cancel operation, a location information request modification operation, a location information request activation operation, a location information request deactivation operation, and the like. The target UE sends an operation request to the LCS system. The LCS system searches for a location information request that meets the requirements of the location information request parameter according to the target UE identification in the operation request, and performs the corresponding operation according to the search result. Then the LCS system sends an operation response to the target UE. . In addition, the target UE can also set the enhancement conditions of the currently initiated enhancement operation. The LCS system searches for a location information request that meets the enhancement conditions according to the target UE identification in the enhancement operation request, and executes the corresponding enhancement operation according to the search result. Then, the LCS system Send an operation response to the target UE. The operation response described above may carry the operation execution result or failure information.

 FIG. 2 is a flowchart of interaction processing when a user initiates an operation. As shown in FIG. 2, when a user initiates an operation, the interaction process between the target UE and the LCS system includes the following steps:

 Step 201: After the target UE establishes a connection with the LCS system, it sends an operation request to the LCS system.

 Steps 202 to 203: The LCS system first performs a search according to the target UE identifier in the operation request, and then performs related operations based on the search results. After the operation is completed, the LCS system determines whether the target UE currently uses the released resource type as active release or active release. For passive release, if the target UE uses an active release resource type, step 204 is performed; otherwise, step 209 is performed.

Steps 204 to 205: The LCS system sends an operation response to the target UE; after receiving the operation response, the target UE determines whether it is necessary to continue the operation, and if so, performs step 206; Otherwise, go to step 207.

 Step 206: The target UE sends a new operation request to the LCS system. After the LCS system receives the new operation request, it returns to step 202, that is, the LCS system performs a new operation according to the new operation request.

 Steps 207 to 208: The target UE sends an end request to the LCS system and releases the resources at the same time; after receiving the end request, the LCS system releases the corresponding resources and ends the current operation.

 Steps 209 to 210: The LCS system sends an operation response and a resource release indication to the target UE, and releases the resources at the same time; after receiving the operation response and the resource release indication, the target UE releases the corresponding resources.

 In the process in which the target UE sends an operation request to the LCS system, the target UE may send the operation request directly to the LCS system, or may send the operation request to the LCS system through the application server, that is, the target UE first sends the operation request to an application server. The application server forwards the received operation request to the LCS system. For example, the target UE edits an operation request in the form of a short message, and then sends the operation request in the form of a short message to the application server. The application server sends the operation request to the application server according to the received short message. The LCS system sends an operation request; or the target UE dials a special number and feeds back the application server's desired operation request to the application server through the voice prompt of the application server. The application server sends a corresponding operation request to the LCS system according to the feedback information of the target UE. . During the process in which the LCS system sends an operation response to the target UE, the LCS system can send the operation response directly to the target UE, or it can send the operation response to an application server, and the application server forwards the received operation response to the target UE. For example, the application server edits the operation response content sent by the LCS system into a short message format, and then sends it to the target UE, or the application server plays the corresponding prompt voice to the target UE according to the content of the LCS system operation response. The application server may be located inside the LCS system or outside the LCS system.

The following is a general query operation of location information request and a normal cancellation operation of location information request. Example, which details the specific implementation process of the interactive operation between the target UE and the LCS system in the present invention. The general query operation of the location information request means that the target UE queries the LCS system for the location information request initiated by it; the general cancellation operation of the location information request means that the target UE notifies the LCS system to cancel the location information request initiated by the target UE.

 FIG. 3 is a flowchart of the general query operation of the location information request. As shown in FIG. 3, the implementation of the general query operation of the location information request includes the following steps:

 Step 301: After the target UE establishes a connection with the LCS system, it sends a general query request to the LCS system to query the location information request initiated by it. The general query request carries the target UE identifier and the general query result returned by the LCS system, that is, the returned location information request parameters, such as the requester identifier; the location information request type, namely, immediate location information request or delayed location information request; The way in which the requesting end requests the location information of the target UE, that is, the client identifier and the like. In addition, the target UE may also preset the location information request parameters required by the LCS system in the LCS system. At this time, the general query request sent by the target UE may not carry the location information request parameters, and subsequent operations are processed by the LCS system by default.

 Step 302: After receiving the general query request, the LCS system searches for a location information request initiated by the target UE in the system according to the target UE identifier.

 Because the target UE needs to establish a connection with the LCS system when performing a general query operation of the location information request, and needs to occupy resources at this time, the present invention divides the active UE's active and passive resource release into two after the general query operation of the location information request ends. Type to meet the different needs of users, thereby increasing the flexibility of the LCS system. Each type defines the operation flow corresponding to each case for the success and failure of the general query operation for the location information request.

 The target UE actively #puts the resource's location information request for a normal query operation to successfully include the following steps:

Step 303a: The LCS system searches for a qualified location information request and is able to execute the request Location information requests normal query operations. The LCS system lists the searched location information request initiated by the target UE according to the location information request parameters returned by the target UE, that is, arranges the location information requests that meet the requirements into a table, and sends the list information to the target UE. For example, the location information request parameter returned by the target UE from the LCS system is the requester identification, and the LCS system arranges the searched location information request for the target UE into a table according to the requester identification, and sends the list to the target UE; or the target UE It is required that the location information request parameter returned by the LCS system is a delayed location information request. The LCS system arranges the searched type of location information request for the target UE, arranges it into a table according to the delayed location information request, and sends the list to the target UE.

 Step 304a: After the target UE receives the general query result, if the target UE needs to continue the operation, it sends a new operation request to the LCS system, and the LCS system performs subsequent operations; otherwise, the target UE sends an end request to the LCS system and releases resources at the same time . After the LCS system receives the end request, it releases the corresponding resources and ends the current location information request operation process. The above new operation request may be a general query request or other operation request, such as a general cancel request.

 The target UE actively releases the location information request of the resource, and the normal query operation fails includes the following steps:

 Step 303b: The LCS system does not find a qualified location information request, or is unable to perform a general query operation of the location information request. The LCS system sends a general query failure message to the target UE, and the general query failure information carries the corresponding failure cause value. The common query fails because the LCS system does not search for the location information request initiated by the target UE, or fails to arrange the searched location information request into a table according to the location information request parameters returned by the target UE.

Step 304b: After the target UE receives the general query failure information, if the target UE needs to continue the operation, it sends a new operation request to the LCS system, and the LCS system performs subsequent operations; otherwise, the target UE sends an end request to the LCS system and releases resources at the same time . LCS system After the end request, the corresponding resources are released, and the current location information request operation process is ended.

 The target UE passively releases the location information request of the resource, and the normal query operation successfully includes the following steps:

 Step 303c: The LCS system searches for a qualified location information request, and can perform a general query operation of the location information request. The LCS system lists the searched location information requests initiated by the target UE according to the location information request parameters returned by the target UE, that is, arranges the location information requests that meet the requirements into a table, and sends the list information to the target UE. 'At the same time, the LCS system sends a resource release indication to the target UE. The above-mentioned new operation request may be a general query request or other operation request, such as a normal cancellation request.

 Step 304c: After the LCS system sends the general query result and the resource release instruction, it directly releases the resources. After receiving the general query result and the resource release instruction, the target UE directly releases the corresponding resource. The target UE receives a resource release indication, indicating that the target UE can no longer perform operations, and the target UE no longer sends an end request to the LCS system, but directly releases resources to end the current location information request operation process.

 The target UE passively releases the location information request of the resource, and the normal query operation fails includes the following steps:

 Step 303d: The LCS system does not find a qualified location information request or cannot perform a general inquiry operation of the location information request. The LCS system sends a general inquiry failure message to the target UE. The general inquiry failure information carries the corresponding failure cause value. At the same time, the LCS system sends a resource release indication to the target UE.

 Step 304d: After the LCS system sends the general query failure information and the resource release instruction, it releases the resources directly. The target UE directly releases the corresponding resources after receiving the general query failure information and the peak resource indication, and ends the current location information request operation process.

In addition, for the case where the general query operation of the location information request is partially successful, that is, the LCS system can only successfully return a part of the general query information of the location information request parameter, or the LCS system It can only successfully return a part of the general query information requested by the location information, and the LCS system can perform subsequent processing with the target UE through a certain negotiation mechanism or according to the preset settings of the target UE. For example, in the general query operation of the location information request, the LCS system searches for three active location information requests initiated by the target UE, but the LCS system cannot perform a list according to the requester ’s identity and return the location information request according to the request of the target UE. If the LCS system can only return all the information for two of the location information requests, or if the LCS system can only return a part of the information for three location information requests, the subsequent processing can be determined through the negotiation mechanism between the LCS system and the target UE, For example, the LCS system notifies the target UE that the general query operation is partially successful, and asks the target UE if it needs to send the general query results. If the target UE needs to send, the LCS system sends the general query results related to the identity of the requester to the target UE. The UE receives the current general query result; if the target UE does not need to send it, continue the operation or end the current location information request operation process; or the LCS system determines whether to send the current general query to the target UE through the preset settings of the target UE in the LCS system. As a result, then continue to exercise Make or end the current location information request operation process.

 FIG. 4 is a flowchart of the normal cancellation operation of the location information request. As shown in FIG. 4, the implementation process of the normal cancellation operation of the location information request includes the following steps:

 Step 401: After the target UE establishes a connection with the LCS system, it sends a normal cancellation request to the LCS system, and cancels the location information request initiated to it. The ordinary cancellation request carries the target UE identifier and the ordinary cancellation result required by the LCS system, that is, the returned location information request parameters, such as the requester identifier; the location information request type, namely, the immediate location information request or the delayed location information request; The way in which the requesting end requests the location information of the target UE, that is, the client identifier and the like. In addition, the target UE may also preset the location information request parameters required by the LCS system in the LCS system. At this time, the normal cancellation request sent by the target UE may not carry the location information request parameters, and subsequent operations are processed by the LCS system by default.

Step 402: After receiving the normal cancellation request, the LCS system searches according to the target UE identity. A request for location information initiated by the target UE in the system.

 Because the target UE needs to establish a connection with the LCS system when performing the normal cancellation operation of the location information request, and resources need to be occupied at this time, after the normal cancellation operation of the location information request is completed, the target UE actively divides and releases resources into passive release resources. To meet the different needs of users, thereby increasing the flexibility of the LCS system. Each type defines the operation flow corresponding to each case for the success and failure of the location information request ordinary cancellation operation.

 The target UE actively releases the location information request of the resource, and the normal cancellation operation successfully includes the following steps:

 Step 403a: The LCS system searches for a qualified location information request, and the LCS system cancels the qualified location information request initiated by the target UE, and notifies the corresponding requesting end that the target UE has cancelled the location information request initiated by it. The LCS system determines whether it can request the cancelled position information, and performs a list according to the position information request parameters returned by the target UE. If it can, the LCS system lists the cancelled position information request initiated by the target UE according to the position information request parameters returned by the target UE, that is, arranges the position information requests that meet the requirements into a table, and sends the list information. To the target UE. For example, the location information request parameter returned by the target UE from the LCS system is the identity of the requester, and the LCS system will cancel the location information request initiated by the target UE and send it to the target UE according to the identity of the requester; or the target UE requires the LCS system The returned location information request parameter is a delayed location information request. The LCS system will cancel the location information request initiated by the target UE, and list and send it to the target UE according to the delayed location information request; otherwise, the LCS system sends to the target UE. Returns failure information.

Step 404a: After the target UE receives a normal cancellation result or returns failure information, if the target UE needs to continue the operation, it sends a new operation request to the LCS system, and the LCS system performs subsequent operations; otherwise, the target UE sends an end request to the LCS system At the same time Source. After the LCS system receives the end clear request, it releases the corresponding resources and ends the current location information request operation process. The new operation request may be a normal cancellation request or another operation request, such as a general query request.

 The target UE's active release of the location information request for a normal cancellation operation fails includes the following steps:

 Step 403b: The LCS system does not find a qualified location information request, or cannot perform a normal cancellation of the location information request. The LCS system sends a normal cancellation failure message to the target UE. The normal cancellation failure information carries the corresponding failure reason value.

 Step 404b: After receiving the normal cancellation failure information, the target UE sends a new operation request to the LCS system if the target UE needs to continue the operation, and the LCS system performs subsequent operations; otherwise, the target UE sends an end request to the LCS system and releases resources at the same time . After the LCS system receives the end request, it releases the corresponding resources and ends the current location information request operation process. The above-mentioned new operation request may be a normal cancellation request or other operation request, such as a general query request.

 The target UE passively releases the location information request for the normal cancellation of the resource, and the normal cancellation operation includes the following steps:

Step 403c: The LCS system searches for a qualified location information request, and the LCS system cancels the qualified location information request initiated by the target UE, and notifies the corresponding requesting end that the target UE has cancelled the location information request initiated by it. The LCS system determines whether the cancelled location information request can be listed according to the location information request parameters returned by the target UE. If yes, the LCS system lists the cancelled location information request ₅ initiated by the target UE according to the location information request parameters returned by the target UE, that is, arranges the location information requests that meet the requirements into a table, and sends the list information To the target UE, at the same time, the LCS system sends a resource release indication to the target UE; otherwise, the LCS system sends a return failure information and resource release indication to the target UE.

Step 404c: the LCS system indicates the normal cancellation result and the dry release resource instruction, or returns a failure After the information and the resource release instruction are issued, the resources are directly released. The target UE directly releases the corresponding resources after receiving the normal cancellation result and the resource release instruction, or returning the failure information and the resource release instruction. The target UE receives a resource release indication, indicating that the target UE can no longer perform operations. The target UE no longer sends an end request to the LCS system, but directly releases resources to end the current location information request operation process.

 The target UE's passive release of the location information request for the normal cancellation of a failed normal operation includes the following steps:

 Step 403d: The LCS system does not find a qualified location information request, or cannot perform a normal cancellation of the location information request. The LCS system sends a normal cancellation failure message to the target UE, and the normal cancellation failure information carries the corresponding failure reason value. At the same time, the LCS system sends a resource release indication to the target UE.

 Step 404d: The LCS system directly releases the resources after the normal cancellation failure information and the dry release resource instruction are issued. After receiving the normal cancellation failure information and the resource release indication, the target UE directly releases the corresponding resources, and ends the current location information request operation process.

If the target UE does not need the LCS system to return the normal cancellation result, clear identification information may be used in the normal cancellation request to notify the LCS system that it does not need to return the normal cancellation result. The LCS system does not return any normal cancellation result to the target UE according to the identification information The UE and the LCS system continue to operate, or directly release resources, and end the current location information request operation. In addition, for the case where the normal cancellation operation of the location information request is partially successful, that is, the LCS system can only successfully return a portion of the general cancellation information of the location information request parameter. Or, the LCS system can only successfully return a part of the general cancellation information requested by the location information. The LCS system can perform subsequent processing with the target UE through a certain negotiation mechanism or according to the preset settings of the target UE. For example, in the normal cancellation operation of the location information request, the LCS system searches for and cancels three active location information requests initiated by the target UE, but the LCS system cannot follow the target. According to the requirements of the UE, according to the identity of the requester, all the location information requests are returned. The LCS system can only return all the information of two of the location information requests, or the LCS system can only return a part of the information of the three location information requests. The LCS system can only cancel two of the location information requests initiated by the target UE in the active state. Therefore, the LCS system can determine the subsequent processing through the negotiation mechanism between the LCS system and the target UE. For example, the LCS system asks the target UE if it needs to send ordinary information. The cancellation result. If the target UE needs to send, the LCS system sends to the target UE information that can be returned related to the identity of the requesting end, and the target UE receives the current general cancellation result. If the target UE does not need to send, it continues the operation or ends the current location information. Request operation process; or the LCS system determines whether to send the current normal cancellation result to the target UE through the preset settings of the target UE in the LCS system, and then continues the operation or ends the current location information request operation.

 The location information request parameters can be variously limited by the user according to the needs, for example: set to perform general query, normal cancellation, modification operation only for the location information request that is activated.

 In addition, the target UE needs to query or cancel some location information requests under specific conditions. At this time, the target UE and the LCS system can implement various enhanced operations through interaction. The target UE sends an enhanced operation request to the LCS system. The LCS system first searches for a qualified location information request according to the target UE identification in the enhanced operation request, and then executes the corresponding enhanced operation according to the search result. After the operation is completed, the LCS system sends the target UE to the target UE. Operation response. The response can contain the operation execution result or failure information.

FIG. 5 is a flowchart of a location information request enhancement operation. As shown in FIG. ₅ , the implementation process of the location information request enhancement operation includes the following steps:

Step 501: The target UE sets an enhancement condition of the currently initiated enhancement operation. The enhancement condition may be carried by the target UE in an enhancement operation request and sent to the LCS system, or may be directly set in advance by the target UE in the LCS system. Steps 502 to 504: After the target UE establishes a connection with the LCS system, it sends an enhanced operation request to the LCS system, and the LCS system searches for a location information request that meets the requirements according to the enhanced conditions; the LCS system determines whether it can search for a location information request that meets the conditions. If yes, go to step 505; otherwise, go to step 506.

 Step 505: The LCS system determines whether related enhanced operations can be performed on the searched location information request. If so, according to the search results, the corresponding enhanced operations are performed according to the enhanced conditions, and then step 507 is performed; otherwise, step 506 is performed.

 Step 506: The LCS system sends enhanced operation failure information to the target UE.

 Step 507: The LCS system sends the enhanced operation result to the target UE.

 The following describes the implementation process of the enhanced operation by taking the location information request specified query operation, the location information request enhanced cancellation operation, and the location information request specified cancellation operation as examples. The location information request specified cancellation operation is further divided into the cancellation of the location information request ordinary specified operation and the location. The information request enhancement specifies a cancel operation.

 The location information request designation query operation refers to that the target UE queries the execution status and status of the specified location information request, for example, the target UE specifies the execution status and status of the location information request initiated by the requester whose query ID is 123.

 FIG. 6 is a flowchart of a location information request designation query operation. As shown in FIG. 6, the implementation process of the location information request designation query operation includes the following steps:

Step 601: After the target UE establishes a connection with the LCS system, it sends a specified query request to the LCS system to specify the execution status and status of the query for the location information request with a certain characteristic. The specified query request carries the target UE identifier, the location information request parameters required by the LCS system, and the specified location information request characteristics that require the LCS system query, such as a specified requester identifier, or a limited parameter such as the determined LCS client identifier; It may also be a logical combination of multiple limited parameters, such as a combination of a specified requester ID and a specified client ID, or a combination of a specified requester ID and a delayed location information request type. In addition, the target UE can The system requests the location information request parameters returned by the LCS system in advance. In this case, the specified query request sent by the target UE may not carry the location information request parameters, and subsequent operations are processed by the LCS system by default.

 Step 602: After receiving the specified query request, the LCS system searches for the execution status and status of the location information request that meets the characteristics of the location information request initiated by the target UE in the system according to the target UE identity.

 The target UE actively releases the resource location information request to specify that the query operation succeeded includes the following steps:.

 Step 603a: The LCS system searches for a qualified location information request and is able to perform a location information request designated query operation. The LCS system performs a list according to the location information request parameters returned by the target UE, that is, arranges the qualified location information requests into a table according to the location information request parameters, and sends the list information to the target UE. For example, the location information request characteristic set by the target UE is that the LCS client identifier is 123, the location information request parameter required by the LCS system is the requester identifier, and the LCS system identifies the requester corresponding to all location information requests with the LCS client identifier as 123. The identifiers are arranged into a table and the list is sent to the target UE; or the location information request characteristic set by the target UE is a delayed location request type, and the location information request parameters required by the LCS system are the requester identifier and the status of the current request. The LCS system lists all delayed location information requests according to the identity and status of the requester and sends them to the target UE.

Step 604a: After the target UE receives the specified query result, if the target UE needs to continue operations, it sends a new operation request to the LCS system, and the LCS system performs subsequent operations; otherwise, the target UE sends an end request to the LCS system and releases resources at the same time . After receiving the end request, the LCS system releases the corresponding resources and ends the current location information request operation process. The new operation request may be a specified query request or other operation request, such as an enhanced cancellation request or a general query operation request. The target UE actively releases the location information request for the specified query operation to fail, including the following steps:

 Step 603b: The LCS system does not search for a qualified location information request, or cannot perform a location information request specified query operation. The LCS system sends the specified query failure information to the target UE, and the specified query failure information carries the corresponding failure cause value. The reason for the specified query failure is that the LCS system does not search for a qualified location information request to the target UE, or fails to return the specified query result according to the location information request parameters returned by the target UE.

 Step 604b: After the target UE receives the specified query failure information, if the target UE needs to continue operations, it sends a new operation request to the LCS system, and the LCS system performs subsequent operations; otherwise, the target UE sends an end request to the LCS system and releases resources at the same time . After the LCS system receives the end request, it releases the corresponding resources and ends the current location information request operation process. The above new operation request can be a specified query request or other operation request, such as an enhanced cancellation request or a normal cancellation operation request.

 The location information request for the target UE to passively release resources successfully specifies the query operation including the following steps:

 Step 603c: The LCS system searches for a qualified location information request, and can execute a location information request designated query operation. The LCS system sends the specified query result to the target UE. At the same time, the LCS system sends a resource release indication to the target UE.

 Step 604c: After the LCS system issues the designated query result and the dry release resource instruction, it directly releases the resource. After receiving the specified query result and the resource release instruction, the target UE directly releases the corresponding resource. The target UE receives a resource release indication, indicating that the target UE can no longer perform operations, and the target UE no longer sends an end request to the LCS system, but directly releases resources to end the current location information request operation process.

The target UE's passive dry release of the location information request for the specified query operation fails includes the following steps: Step 603d: The LCS system does not find a qualified location information request, or cannot perform a location information request designated query operation. The LCS system sends the designated query failure information to the target UE, and the designated query failure information carries the corresponding failure cause value. At the same time, the LCS system sends a resource release indication to the target UE.

 Step 604d: The LCS system directly releases the resources after the specified query failure information and the resource release instruction are issued. After receiving the specified query failure information and the resource release instruction, the target UE directly releases the corresponding resources and ends the current location information request operation process.

 In addition, for the case where the specified query operation of the location information request is partially successful, that is, the LCS system can only successfully return a part of the specified query information of the location information request parameter, or the LCS system can only successfully return a part of the specified query information of the location information request. The LCS system can Follow-up processing is performed with the target UE through a certain negotiation mechanism, or according to the preset settings of the target UE. For example, during a location information request designation query operation, the location information request parameter returned by the target UE to the LCS system is the requester identification. The LCS system can only search for the immediate location information request initiated by the requester, but cannot find the request. The content of the delayed location information request initiated by the requester, so that the LCS system cannot return all the specified query information of the location information request initiated by the requester according to the request of the target UE, so the LCS system can negotiate with the target UE The mechanism determines subsequent processing. For example, the LCS system asks the target UE whether it needs to send the specified query result. If the target UE needs to send, the LCS system sends the specified query information related to the requester that can be returned to the target UE, and the target UE receives the current specified query. Result; if the target UE does not need to send, continue with subsequent processing or directly release resources to end the current location information request operation process; or determine whether to send the current specified query to the target UE through the preset settings of the target UE in the LCS system As a result, Continue to operate, or direct current resource release end position information request operation.

FIG. 7 is a basic flowchart of the enhanced cancellation operation of the location information request. As shown in FIG. 5, the basic implementation process of the enhanced cancellation operation of the location information request includes the following steps: Steps 701 to 703: After the target UE establishes a connection with the LCS system, it sends an enhanced cancellation request to the LCS system. After receiving the enhanced cancellation request, the LCS system searches for a qualified location information request; the LCS system determines whether it can search for qualified If the location information is requested, go to step 704; otherwise, go to step 705.

 Step 704: The LCS system determines whether the searched location information request can be cancelled, and if so, executes step 706; otherwise, executes step 705.

 Step 705: The LCS system sends enhanced cancellation failure information to the target UE, the enhanced cancellation failure information carries a corresponding failure reason value, and then ends the current location information request enhanced cancellation operation process.

 Step 706: The LCS system judges whether the location information request parameter can be returned to the target UE and returns the relevant content of the cancelled location information request. If so, step 709 is performed. Further, the LCS system may perform step 707; otherwise, step 708 is performed. .

 Step 707: The LCS system notifies the corresponding requester that the target UE has canceled the location information request it initiated.

 Step 708: The LCS system negotiates subsequent operations with the target UE, and then ends the current location information request operation process.

 Step 709: The LCS system sends an enhanced cancellation result to the target UE, and ends the current location information request enhanced cancellation operation flow.

 There are three types of limited ranges for the location information request enhanced cancellation operation initiated by the target UE: time limited range, regional limited range, and time and regional combination limited range.

The time zone limited location information request enhanced cancellation operation refers to that the target UE defines a valid time range in the enhanced cancellation request, and requires the LCS system to cancel or reject the location information request initiated by it within this time period. The definition of the effective time range needs to be set in advance by the target UE and the LCS system. For example, given two time periods, the first time period indicates the time from the current time point to the start of canceling the location information request operation, and the second time . The segment indicates the length of time required to cancel the location information request operation.

 Location-restricted location information request enhanced cancellation operation refers to that the target UE defines a valid geographical range in the enhanced cancellation request, and requires the LCS system to cancel or reject the location information request initiated by the target UE when the target UE is within the geographical range. . The definition method of the effective geographical range requires the target UE and the LCS system to be set in advance, and a representation method that can be recognized by the LCS system, such as a latitude and longitude representation method; and the geographical range given by the target UE needs to be within the geographic accuracy range of the LCS system. . For areas beyond the geographic accuracy of the LCS system, the LCS system can directly reject the target UE ’s request for enhanced location cancellation of the location restriction information and return error information to the target UE; or the LCS system can negotiate with the target UE, such as the LCS system Adjust the geographic range defined by the target UE according to the accuracy range that can be satisfied by itself, and then send relevant prompt information to the target UE.

 The enhanced cancellation operation of the location information request with limited time and region combination means that the target UE defines a valid time range and geographical range in the enhanced cancellation request, and requires the LCS system to cancel or cancel when the target UE is within the geographical range within the time period. Decline a location request from him.

 FIG. 8 is a flowchart of the enhanced cancellation operation of the location information request. As shown in FIG. 8, the enhanced cancellation operation of the location information request includes the following steps:

Step 801: After the target UE establishes a connection with the LCS system, it sends an enhanced cancellation request to the LCS system, and cancels or rejects the location information request initiated to it within a limited range. The enhanced cancellation request carries the target UE identity, the enhanced operational limitation of the cancellation request, and the enhanced cancellation result information required by the LCS system, that is, the returned location information request parameters, such as the requester identifier; the location information request type, namely, the immediate location Information request or delayed type location information request; The way in which the requester requests the location information of the target UE, that is, the client identifier, etc. The operation limited range of the enhanced cancellation request may be a time limited range, or a regional limited range, or a time and geographical combination limited range. In addition, the target UE can set the LCS system in advance in the LCS system. The system returns the location information request parameters. At this time, the enhanced cancellation request sent by the target UE may not carry the location information request parameters, and the LCS system performs default return information processing according to the settings.

 Step 802: After receiving the enhanced cancellation request, the LCS system searches for a qualified location information request initiated by the system for the target UE according to the target UE identity.

 The location information requested by the target UE to actively release the resource and the enhanced cancellation operation successfully includes the following steps:

Step 803a: The LCS system searches for a qualified location information request, and the LCS system determines whether it can cancel the qualified location information request to the target UE. If not, the LCS system sends an enhanced cancellation return failure message to the target UE; otherwise, The LCS system judges whether the enhanced cancellation result can be returned, that is, the cancelled location information request, performs a list according to the location information request parameters returned by the target UE, and returns to the target UE. If so, the LCS system cancels the eligible location information request to the target UE and notifies the corresponding requester that the target UE has cancelled its location information request. At the same time, the LCS system will cancel the location initiated by the target UE. The information request is a list according to the location information request parameters returned by the target UE, that is, the location information requests that meet the requirements are arranged into a table according to the location information request parameters, and the list information is sent to the target UE. For example, the location information request parameter returned by the target UE requested by the LCS system is the requester identification, and the LCS system will cancel the location information request initiated by the target UE according to the requestor identification and send it to the target UE; or the target UE requires the LCS system The returned location information request parameter is a delayed location information request. The LCS system will cancel the location information request initiated by the target UE according to the delayed location information request and send it to the target UE. If the LCS system cannot return the enhanced cancellation result, that is, the LCS system cannot list the cancelled location information request and return it to the target UE according to the location information request parameters requested by the target UE. At this time, a processing method is that the LCS system cannot return When the enhanced cancellation result is inquired, whether the target UE continues to perform the enhanced cancellation operation. If the target UE confirms that the enhanced cancellation operation is to be continued, then The LCS system cancels the qualified location information request initiated by the target UE, and notifies the corresponding requester that the target UE has cancelled the location information request initiated by it. The LCS system may further return the enhanced cancellation result that can be returned to the target UE. If the enhanced cancellation operation needs to be performed, follow-up processing is performed, or the current location information is requested to end the enhanced cancellation operation flow of the current location information. Another processing method is that the LCS system determines whether to continue the enhanced cancellation operation according to the preset settings, and whether to perform the enhanced cancellation operation to the target UE. Send the current enhanced cancellation result, and then continue the operation, or directly release resources to end the current location information request operation process.

 Step 804a: After the target UE receives the enhanced cancellation result or the enhanced cancellation return failure information, if the target UE needs to continue the operation, it sends a new operation request to the LCS system, and the LCS system performs subsequent operations; otherwise, the target UE ends the sending to the LCS system Request, while releasing resources. After receiving the end request, the LCS system releases the corresponding resources and ends the current location information request operation process. The above new operation request may be an enhanced cancellation request or other operation request, such as a specified query request or a normal cancellation operation request.

 The target UE's active release of the location information request for enhanced cancellation fails, including the following steps:

 Step 803b: The LCS system does not find a qualified location information request, or cannot perform an enhanced cancellation operation of the location information request. The LCS system sends enhanced cancellation failure information to the target UE, and the enhanced cancellation failure information carries the corresponding failure cause value.

 Step 804b: After the target UE receives the enhanced cancellation failure information, if the target UE needs to continue the operation, it sends a new operation request to the LCS system, and the LCS system performs subsequent operations; otherwise, the target UE sends an end request to the LCS system and translates Resources. After the LCS system receives the end request, it releases the corresponding resources and ends the current location information request operation process. The above new operation request may be an enhanced cancellation request or other operation request, such as a designated query request or a general cancellation operation request.

The target UE passively releases the location information request for enhanced cancellation. The successful cancellation operation includes the following: Steps:

 Step 803c: The LCS system searches for a qualified location information request, and the LCS system determines whether it can cancel the qualified location information request to the target UE. If not, the LCS system sends the enhanced UE failure return information and releases resources to the target UE. Indication; otherwise, the LCS system judges whether it can return the enhanced cancellation result, that is, the cancelled position information request, performs a list according to the position information request parameters returned by the target UE, and sends the list information to the target UE, and if so, the LCS The system cancels the eligible location information request to the target UE, and notifies the corresponding requester that the target UE has cancelled its location information request. Then, the LCS system will cancel the location information request initiated by the target UE according to the The position information request parameters that the target UE requires to be returned are listed, that is, the position information requests that meet the requirements are arranged into a table, and the list information is sent to the target UE. At the same time, the LCS system sends a dry release resource indication to the target UE. If the enhanced cancellation result cannot be returned, the LCS system may negotiate with the target UE to process subsequent operations.

 Step 804c: The LCS system will enhance the cancellation result and release the resource instruction, or enhance the cancellation to return the failure information and release the resource instruction, and then release the resource directly. The target UE directly releases the corresponding resources after receiving the enhanced cancellation result and the resource release instruction, or the enhanced cancellation return failure information and the resource release instruction. The target UE receives a resource release indication, which indicates that the target UE can no longer perform operations. The target UE no longer sends an end request to the LCS system, but directly releases resources and ends the current location information request operation process.

 The target UE's active release of the location information request for enhanced cancellation fails, including the following steps:

Step 803d: The LCS system does not find a qualified location information request, or cannot perform a location information request enhanced cancellation operation. The LCS system sends enhanced cancellation failure information to the target UE, and the enhanced cancellation failure information carries the corresponding failure cause value. At the same time, the LCS system sends a resource release indication to the target UE. Step 804d: The LCS system releases the enhanced cancellation failure information and the resource release instruction directly after issuing. After receiving the enhanced cancellation failure information and the dry release resource indication, the target UE directly releases the corresponding resources, and ends the current location information request operation process.

 The above process only describes the process in which the target UE initiates a location information request enhanced cancellation operation and the LCS system returns a preliminary search result. In the subsequent process of this process, the LCS system will reject the location information request initiated by the target UE within the effective operation limit of the enhanced cancellation operation with the location information request, that is, the LCS system will also reject the subsequent process within the effective operation limit. The location information request initiated by the target UE is used to implement the function of enhancing the cancellation operation of the location information request.

 According to the user's needs, the target UE can determine whether to reject the location information request for enhanced cancellation. After the effective operation is limited, the location information request to the target UE is initiated in the subsequent process. After the LCS system receives the location information request from the target UE in the subsequent process, the LCS system asks the target UE whether to cancel the location information request. If the target UE sends a confirmation message to the LCS system, the LCS system rejects the location information request and sends the request to the corresponding The requesting end sends rejection information; otherwise, the location information of the target UE is provided to the corresponding requesting end.

In addition, for the case where the enhanced cancellation operation of the location information request is partially successful, that is, the LCS system can only successfully return a portion of the enhanced cancellation information of the location information request parameter, or only the enhanced cancellation information of the location information request parameter, the LCS system can Follow-up processing is performed with the target UE through a certain negotiation mechanism or according to a preset setting of the target UE. For example, in the enhanced cancellation operation of the location information request, the target UE requests to cancel all active location information requests in a certain area, and returns all the relevant information of the location information request. The LCS system searches for three eligible targets. Location information request initiated by the UE, but the LCS system cannot return the three location information requested information according to the requirements of the target UE, and the LCS system can only return two or three of the active location information requests initiated by the target UE. The LCS system can only cancel two of them, so it can be connected with the LCS system. The negotiation mechanism of the target UE determines the subsequent processing. For example, the LCS system asks the target UE whether to continue the cancellation operation. If the target UE confirms the continuation, the LCS system cancels the eligible location information request initiated by the target UE and can notify the notification. Correspondingly, the target UE has cancelled the location information request it initiated, and the LCS system can further send the information related to the requester to the target UE, and the target UE receives the enhanced cancellation result; if the target UE does not need to continue executing Cancel the operation, continue the operation, or directly release the resource to end the current location information request operation process; or determine in advance the target UE in the LCS system whether to perform the enhanced cancellation operation and whether to send the enhanced cancellation result to the target UE, Then continue the operation, or directly direct the resources to end the current position information request operation process.

 Within the effective operation limit corresponding to the type of enhanced cancellation operation for location information request, if the target UE needs to locate itself, or an emergency service, or a legitimate tracking service needs to locate the target UE, it can be sent to the LCS system The target UE identification and location information request. At this time, the LCS system may consider this type of request to be a location information request with an unauthorized capability, without canceling or rejecting it.

 Corresponding to the location information request specifying query operation, the present invention provides a location information request specifying cancel operation. The cancellation operation of the location information request indicates that the target UE cancels the specified location + location information request. For example, the target UE specifies the location information request initiated by the requester whose cancellation ID is 123.

 The location information request designated cancellation operation is divided into two types: location information request common designated cancellation operation and location information request enhanced designated cancellation operation.

The location information request ordinary designation cancel operation refers to that the target UE provides a specified requester identification, or client identification, or location information request type in the general designation cancellation request, that is, immediate location information request or delayed location information request, etc. The location information request feature requires the LCS system to directly cancel the location corresponding to the location information request feature initiated by the LCS system Information request.

 FIG. 9 is a flowchart of a general designation cancellation operation of a location information request. As shown in FIG. 9, the operation flow is similar to the above-mentioned location information request enhanced cancellation operation flow, except that the target UE sends a general designation cancellation request to the LCS system. , The common designated cancellation request carries the target UE identity, and the common designated cancellation result requested by the LCS system, that is, the returned location information request parameters, and the designated location information request characteristics that need to be cancelled by the LCS system, such as the designated requester identifier, or Location information request characteristics, such as a specified client ID; The logic of multiple location information request characteristics, such as a combination of a specified requester ID and a specified client ID, or a combination of a specified requester ID and a delayed location information request ID combination. Then, according to the target UE identity, the LCS system searches for a location information request in the system that meets the characteristics of the location information request initiated by the target UE, and performs a normal designation cancel operation, and will cancel the cancelled position according to the location information parameters required by the target UE. The information request is made into a list, and then the list information is returned to the target UE, and the corresponding requesting end is notified, and the target UE has canceled the location information request it initiated.

 The enhanced cancellation operation for location information request is based on the enhanced cancellation operation for location information request. The location information request enhancement specified cancellation operation initiated by the target UE can be divided into different operation limits: time limited range location information request enhanced specified cancellation operation, geographically limited range location information request enhanced specified cancellation operation and time and region combination limited range. The location information request enhancement specifies a cancel operation. Time-limited range of location information request enhancements specify cancellation operations, geographically limited range of location-information request enhancements specify cancellation operations and time-region combination limited-range location-information request enhancements specified cancellation operations, effective operation limited-range definitions and location information request enhancements The corresponding definitions in the cancel operation are the same.

FIG. 10 is a flowchart of a location information request enhanced designation cancel operation. As shown in FIG. 10, the operation process is similar to the location information request enhanced cancel operation procedure described above, with the differences The target UE sends an enhanced designated cancellation request to the LCS system. The enhanced designated cancellation request carries the target UE identification, and the enhanced designated cancellation result required by the LCS system is returned location information request parameters, the effective cancellation operation limitation range, and the specified Location information request characteristics that need to be canceled by the LCS system, such as a specified requester identification, or a specified client identification, and a location information request characteristic; it can also be a combination of a specified requester identification and a specified client identification, or a specified request A logical combination of multiple location information request characteristics, such as a terminal identification and a delayed location information request identification combination. Then, the LCS system searches for the location information request that meets the characteristics of the location information request and is within the scope of the effective operation cancellation initiated by the target UE in the target UE identification system, and cancels the operation, and then according to the location information parameters required by the target UE. Make a list of the cancelled location information request, and return the list information to the target UE, and notify the corresponding requesting end, and the target UE cancels the location information request it initiated. The related content of the location information request for the normal cancellation operation and the location information request for the enhanced cancellation operation are similar to the location information request for enhanced cancellation operations, and are not repeated here.

 The enhanced condition in the location information request designation query operation and location information request enhancement designation cancellation operation may be a location information request feature that is limited to the operation. The location information request feature may limit only one operation or multiple different operations, such as Specifies to query or cancel all location information requests that are currently active.

 Each of the above-mentioned location information request ordinary query operation, location information request ordinary cancel operation, location information request designated query operation, location information request enhanced cancellation operation, location information request ordinary designation cancel operation and location information request enhanced designation cancel operation The bearer information that is interacted in the process can be completed by separately defining dedicated information, or by adding parameters to the existing information.

 In short, the above descriptions are merely preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
