Description

A Realization Method of Fixed Line Priority Service

technical field

The invention relates to a method for implementing call forwarding in a telecommunication system.

Background technique

The telephone call transfer service is a service frequently used in the telecommunication system. Common call transfer methods include the following: fixed telephone to fixed telephone, fixed telephone to mobile telephone, mobile telephone to fixed telephone, mobile telephone to mobile telephone, specific The realization of call transfer is realized by setting transfer data in fixed exchange or mobile exchange. Take the realization of call forwarding by fixed phone or mobile phone as an example: firstly, the user needs to apply for service authorization, and then register through the phone after the user has the authority to call forward, so as to notify the switchboard of the call forwarding conditions and the destination phone, that is, Tell the switch the triggering condition of the call forwarding event and the destination address of the forwarding after triggering. The triggering conditions of call forwarding and the destination address of forwarding after triggering are stored in the memory of the switch until the user cancels the call forwarding. For example, assume that user A has applied for the busy call forwarding service, and user A has registered call forwarding on busy to user B on his own phone. When a user calls A, if user A is talking, the exchange will detect that the transfer condition is met, and then obtain the registered destination address B to be transferred from the memory, and initiate a call to the destination address user, the communication system The exchange and the mobile switching center (MSC) are connected to the destination user of the transferred call, and the incoming user talks with the B user.

As can be seen from the above, the shortcoming of the existing method for implementing call forwarding is that, first of all, this method is to solve the problem of calling out from the called mobile user or fixed user, that is, call forwarding is performed on the called phone, and the call forwarding method will meet the conditions. Calls are transferred to other destination phones, and the transfer control cannot be performed by the destination phone. Therefore, the control of fixed phones to mobile calls cannot be realized: Secondly, for the way of transferring mobile phones to fixed phones, MSC in the mobile network is required. Therefore, the tariff for call forwarding is still determined by the mobile network. Compared with the current fixed telephone network tariff, the user pays more.

Contents of the invention

The purpose of the present invention is to provide a method for realizing a fixed-line priority service. By using this method, when a fixed-line phone calls a mobile phone, the call from the mobile phone can be automatically transferred to the fixed-line phone through the fixed-line mode, so as to realize the fixed-line call to the fixed-line phone. Call forwarding control for mobile users.

In order to achieve the above object, the implementation method of the fixed-line priority service provided by the present invention includes:

a. Open the priority fixed-line service in the communication system, and store the transferred mobile phone number of the fixed-line priority service registered by the user in the service control point SCP of the intelligent network connected to the fixed network and the number of the fixed network to which the user is required to transfer telephone number;

b. set the trigger detection condition of the fixed telephone priority service in the service switching point SSP of the intelligent network connected with the fixed network;

c. When the calling fixed phone calls the mobile phone, the service switching point SSP detects that the trigger detection condition is satisfied, and then reports to the service control point SCP;

d. The service control point SCP queries the called mobile phone number corresponding to the registered phone number of the fixed network that requires transfer, and instructs the service switching point SSP of the intelligent network connected to the fixed network to establish The call link from the calling fixed phone to the phone corresponding to the fixed phone number of the fixed network.

The service switching point SSP described in step b is set at the gateway office of the fixed network.

Optionally, step a specifically includes the following steps:

a11. The mobile phone user applies to the fixed network operator for subscription to the fixed phone priority service and obtains the service password;

a12. The mobile phone user enters the access code provided by the fixed network operator, the mobile phone number required to be transferred, and the obtained service password on the phone corresponding to the phone number of the fixed network that is required to be transferred;

a13. Store the mobile phone number as the transferred mobile phone number in the service control point SCP of the intelligent network connected to the fixed network, and the phone number of the fixed network as the phone number of the fixed network to be transferred to.

Optionally, step a specifically includes the following steps:

a21. Mobile phone users apply to the fixed network operator for subscription to fixed-line priority services and obtain service passwords;

a22. The mobile phone user enters the access code provided by the fixed network operator, the phone number of the fixed network to be transferred to and the obtained service password on the mobile phone;

a23. Store the mobile phone number as the transferred mobile phone number and the phone number of the fixed network to which the transfer is required in the service control point SCP of the intelligent network connected to the fixed network.

Detailed ways

The method of the present invention is applicable to the call transfer situation where the fixed telephone is used as the calling party and the mobile phone is used as the called party. It is a method to realize the call transfer of the mobile phone in the public switched telephone network (PSTN) by means of a fixed intelligent network, that is, the method of the present invention Realization depends on the intelligent network system, and the intelligent network system includes at least a service control point SCP and a service switching point SSP.

The present invention will be described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is a flowchart of an embodiment of the method of the present invention. Refer to Fig. 2 for the intelligent network on which the method described in Fig. 1 depends. It is composed of several parts such as service switching point SSP, service control point SCP, intelligent peripheral IP, service management system SMS, and service generation environment SCE. network connection.

Service Switching Point (SSP) is the connection point between the fixed network and the intelligent network system. It is set in the fixed gateway office connecting the fixed network to the mobile network, and provides the function of accessing the intelligent network function set. The SSP can detect the request of the intelligent service, communicate with the service control point SCP, respond to the request of the SCP, and allow the service logic in the SCP to affect the call processing.

Service Control Point SCP (Service Control Point) is the core component of the intelligent network, which stores user data and business logic. The SCP is mainly used to receive the query information sent by the SSP and query the database, and perform various decodings; at the same time, the SCP can start different business logics according to the call events reported by the SSP, and send call control instructions to the corresponding SSP according to the business logic. So as to realize various intelligent calls.

Intelligent terminal IP (Intelligent Peripheral) is a peripheral device that assists in the completion of intelligent services. It usually has voice functions such as speech synthesis, playing recording notifications, speech recognition, and receiving dual-tone multi-frequency dialing. IP can be an independent physical device, or it can be used as a part of SSP. It accepts the control of SCP and executes the operation specified by SCP business logic.

The service management system SMS (Service Management System) includes the service management point SMP and the service management access point SMAP. SMS generally has five functions, namely, business logic management, business data management, user data management, business monitoring, and traffic management. The new business logic created in the business generation environment is input into the SMS by the service provider, and the SMS loads it into the SCP, so that the new business can be provided on the communication network.

Service Creation Environment SCE (Service Creation Environment), used to generate new business logic according to customer needs.

Based on the above-mentioned intelligent network, when the embodiment described in FIG. 1 is actually implemented, firstly, step 1 is performed, and the fixed-line priority service is opened in the communication system, the fixed-line priority service registration of the user is accepted, and the fixed-line priority service registered by the user is stored. Data, in this example, the above-mentioned data is the relevant telephone number, so the data of storing the fixed telephone priority service registered by the user is to store the relevant telephone number in the SCP of the intelligent network. The user registration can be through the service management access point SMAP complete.

The fixed-line priority service registration of the user described in this step adopts two registration methods of fixed-line phone and mobile phone. Application registration includes three parts: account opening registration, business use registration and business use cancellation. The account opening registration refers to registering the mobile phone or fixed phone that opens this service at the system business hall; When registering this service, you need to register this service on the corresponding mobile phone or fixed phone; the service use cancellation is when the location of the mobile phone user changes, or when the mobile phone user does not want to use the service, you can pass this part The operation is canceled.

Assuming that the access code of the fixed-line priority service is 158, when using a fixed-line phone to apply for registration, the service fee will be charged to the fixed-line phone user, and the service fee will not be charged to the mobile phone that is called out. Account opening registration refers to the following process: the user provides fixed-line payment bank account number, ID card and other valid documents, and the system assigns a 158 service password. At this time, the service takes effect and the fixed-line phone can use the service. Refer to the following process for business use registration: enter "158+13XXXXXXXXX+(password)+(call waiting times)+other parameters#" in sequence, and through the above settings, the mobile call with the number 13XXXXXXXXX can be transferred to this fixed phone. Setting Other parameters are to improve some problems in the use of this service. The above registration method can register the incoming calls of multiple mobile phone users, but it must have the authority to transfer the outgoing calls of mobile phones, that is, (password), and the cost is independently borne by the landline .Refer to the following procedure for service use cancellation: Enter #158# in sequence to register the call priority service to the fixed phone and cancel all calls that charge the fixed phone fee.

When using a mobile phone to apply for registration, the service usage fee will be collected from the mobile phone user account, and the fixed phone to which the call is transferred will not be charged. Account opening registration refers to the following process: the user provides mobile phone payment bank account number, ID card and other valid documents, the system requires the user to reserve a certain amount of fees on the account, and sets a 158 business password for the user. At this time, the service takes effect. Mobile phones can use this service. Refer to the following process for business registration: input "158+fixed phone number+(password)+(call waiting times)+other parameters#" in sequence, and through the above settings, the mobile calls of this mobile phone can be transferred to the fixed phone number on the designated landline. Setting other parameters is to improve some problems in this business use. Adopt above-mentioned method, when registering and using this service on the mobile phone to the landline telephone that is called each time, will cancel the previous service registration automatically. Refer to the following process for service use cancellation: input #158# in sequence to transfer all calls transferred out to the mobile phone.

In step 2, in the Service Switching Point (SSP) of intelligent network, be provided with fixed-line preferential service trigger detection mechanism, this example uses the first two " 13 " of the mobile number of fixed-line priority service as the trigger condition of fixed-line priority service;

In order to facilitate the processing of the fixed-line priority service, the service control point SCP of the intelligent network is provided with a fixed-line priority service module including the fixed-line priority service logic processing program and service data in this example. In the case of a mobile phone, the intelligent network detects the called mobile phone in step 3. If the called mobile phone meets the set trigger detection condition, the call is processed according to the business logic of fixed phone priority. That is to say, when the service switching point SSP detects the fixed-line priority service and reports it to the SCP, the SCP interacts with the service switching point SSP and the fixed-line priority service logic affects call processing. That is, the SCP judges whether the called mobile phone is registered in the SCP. If registered, a new call link is established from the calling fixed phone to the transferred fixed phone; Communication link between mobile phones.

Since the intelligent network system shown in Fig. 2 includes a service generation environment SCE, the SCE generates the fixed-line priority service, including the fixed-line priority service logic and service data, and tests it when the present invention is implemented. The system SMS loads the service logic and service data into the SCP to generate a module for handling fixed-line priority services. The intelligent peripheral IP can be set independently or integrated with the service switching point SSP. Specifically, the service generation environment SCE defines the business logic (business process) and business data (database and variables used in the process of service execution) required to realize the fixed-line priority service in the form of software, forming a fixed-line priority service logic software module , thereby generating the fixed-line priority service, and verifying and testing the generated fixed-line priority service. The service management system SMS loads the fixed-line priority service logic, fixed-line priority service data and corresponding software modules into the service control point SCP, and then runs the service. During the operation of the fixed-line priority service, monitor and count the implementation of the fixed-line priority service, and generate reports. It can be removed from the intelligent network when not needed. When the user registers the fixed-line priority service at the system business hall, the user's data information is entered into the corresponding database through SMAP, and the newly added or modified data in the user database is loaded into the SCP through SMS. After the service management system SMS loads the service logic, service data template and service detection point related to the fixed-line priority service into the SCP, a software module for processing the fixed-line priority service is generated in the SCP. Including a fixed-line priority service logic processing program and corresponding user database. Set the fixed-line priority service trigger detection mechanism in the SSP. When the SSP detects the fixed-line priority service, it will report it to the SCP and interact with the SCP.

In the above-mentioned embodiment of the present invention, the connection protocol between each entity of the network is as follows: TCP/IP is between SCE and SMS, wide area network or local area network can be between SMAP and SMS, wide area network or local area network can be between SMS and SCP, SCP Between the SSP and the NO.7 signaling network.

Using the above scheme, when the called mobile phone is in the local area in the fixed-line priority service, any fixed calling user must enter the mobile network through the gateway office of the fixed network, that is, the SSP, when making a call to the mobile user. If the fixed-line preferential call forwarding of the mobile user is registered in the gateway office of the fixed network, the routing of the traffic can be changed by reporting the number "13" of the intelligent network to the SCP, and the original call route from the fixed gateway office to the mobile user will be changed. It is the internal route of the fixed network.

In the fixed-line priority service, when the called mobile phone is roaming, any fixed calling user calls the mobile user, and when the mobile user roams to other cities, the implementation process can also be changed. In the case of normal roaming, the voice path is from the fixed gateway office to the mobile gateway office, then to the mobile toll office, and finally to the mobile phone user; while using the fixed line priority service, the signaling route is: the fixed gateway office (SSP) will The mobile phone number is reported to the SCP, then to the fixed toll office, and then to the mobile phone where the call is transferred; traffic routing is from the source fixed toll office to the destination fixed toll office, and then to the destination fixed phone where the call is transferred.

In short, the fixed line priority service automatically transfers the calls of the mobile phone to the fixed phone through the control of the fixed phone, which can realize the call transfer control of the fixed network to the mobile user; reduce the user's charge for answering the phone and reduce radiation, especially suitable for roaming Reduce mobile phone tariffs; and increase long-distance revenue for fixed-line operators when roaming.
