Description

A method and system for providing positioning service information

technical field

The present invention relates to the technical field of mobile communication, in particular to a method and system for providing positioning service information in the technical field of mobile user terminal positioning service.

Background technique

At present, in the field of mobile communication technology, the positioning service of specialized mobile user terminals has been realized. In the mobile communication network, there are dedicated positioning service clients (Location Services Client, LCSClient), and mobile positioning service gateway bureaus (Gateway Mobile Location Centre, GMLC). ), and even network element equipment such as the Global Positioning System (GPS). Moreover, a new set of positioning service-specific messages and complex positioning algorithms are added in the mobile communication network to complete the precise positioning of mobile user terminals.

There are mainly three ways to realize the positioning of mobile user terminals:

The first is the mobile terminal positioning service (LCS MT_LR), which is initiated by the LCS Client and performs position positioning on the mobile user terminal (Mobile Station, MS).

As shown in Figure 1, the mobile terminal positioning service includes the following steps:

S011. The LCS Client initiates a called location request to the GMLC;

S012, GMLC provides mobile user terminal location information to Mobile Switching Center/Visitor Location Register (Mobile Switching Center/Visitor Location Register, MSC/VLR);

S013, the mobile user authentication and encryption process is completed between the MSC/VLR and the MS, which is an optional step;

S014. The MSC/VLR sends a positioning request notification message to the MS, which is an optional step;

S015. The MS replies to the MSC/VLR with a positioning request notification response message, which is an optional step;

S016, MSC/VLR sends a positioning request message to a radio access network/base station subsystem (RadioAccess Network/BaseStation System, RAN/BSS), wherein RAN is 3G RAN, and BSS is 2G BSS;

S017, RAN/BSS, MS and GPS obtain the precise position of MS through complex interaction process and positioning algorithm;

S018. The RAN/BSS sends a location report message to the MSC/VLR;

S019, MSC/VLR provides user location response message to GMLC;

S0110. The GMLC submits a positioning result report to the LCS Client, and the positioning service is completed.

The second is the mobile origin location service (LCS MO_LR), which is initiated by the MS to locate itself.

As shown in Figure 2, the mobile-originated positioning service includes the following steps:

S021, the MS sends a call management service request to the MSC/VLR;

S022, completing the authentication, encryption, and call management service acceptance process between the MS and the MSC/VLR;

S023, the MS sends a positioning service request to the MSC/VLR;

S024, the MSC/VLR sends a location request message to the RAN/BSS;

S025, RAN/BSS, MS and GPS obtain the precise position of MS through complex interaction process and positioning algorithm;

S026. The RAN/BSS sends a location report message to the MSC/VLR;

S027, MSC/VLR sends mobile application part (Mobile Application Part, MAP) user location report message to GMLC, and this step is an optional step;

S028, GMLC replies MAP user location report response message to MSC/VLR, this step is an optional step;

S029. The MSC/VLR sends a positioning result sending message to the MS;

S0210. The GMLC sends a positioning result report to the LCS Client. This step is an optional step, and the positioning service is completed.

The third is the location service initiated by the network (LCS NI_LR), which is a service initiated by the switch where the MS is located when the MS initiates an emergency call to locate the MS.

As shown in Figure 3, the positioning service initiated by the network includes the following steps:

S031, the MS sends a call management service request to the MSC/VLR;

S032, the caller access process is completed between the MS and the MSC/VLR;

S033. The MS sends an emergency call origination message to the MSC/VLR;

S034, the MSC/VLR sends a location request message to the RAN/BSS;

S035, RAN/BSS, MS and GPS obtain the precise position of MS through complex interaction process and positioning algorithm;

S036. The RAN/BSS sends a location report message to the MSC/VLR;

S037, the MSC/VLR sends a MAP user location report message to the GMLC;

S038, GMLC replies MAP user location report response message to MSC/VLR;

S039. The GMLC sends a positioning result report to the LCS Client, and the positioning service is completed.

From the above three positioning service methods, it can be seen that the existing technical solutions for positioning services have some disadvantages: special network element equipment is required, such as: LCS Client, GMLC, etc.; all relevant network elements are required to support new messages for positioning services; MS supports the initiation of positioning services and the display of positioning results, but currently few MSs can support this function; no matter which of the above initiation processes, LCS MT_LR, LCSMO_LR, LCS NI_LR, positioning services require a special initiation process, which cannot be initiated by mobile users. The method of signing in advance is automatically initiated when the mobile user terminal location is updated, switched, or called.

Contents of the invention

The present invention provides a method and system for providing positioning service messages, which are used to solve the problems in the prior art that special network element equipment and adding new messages are required to realize positioning services, and the positioning services cannot be initiated automatically.

The method for providing positioning service information in the present invention includes:

A method for providing positioning service information, comprising the following steps:

S109. In order to avoid always displaying the location information on the subsequent MS without the operator identification, after displaying all the location information and before the MS re-updates the location or switches to another area, the MSC/VLR needs to The mobile subscriber IMSI obtains the operator identification (here also can realize by setting up the mode of data table on the exchange), and brings MS through the network name full name (Fullname for network) cell of the mobility management information message, and restores on the MS screen as The operator's identification, when all the information is sent, the wireless resources will be released.

Specific implementation mode 2:

As shown in Figure 5, it is a schematic flow chart of the embodiment 2 of the present invention, as can be seen from the figure, it mainly includes the following steps:

Among them, S201 and S202 are respectively consistent with S101 and S102;

S203. The mobile user dials the special service number corresponding to the positioning service, and the MSC/VLR checks whether the supplementary service list of the MS includes an operator-defined supplementary service code corresponding to the positioning service. For example, 0xFA, if there is, it means that the MS has subscribed to the positioning service; if not, notify the mobile user terminal that the mobile user terminal has not subscribed to the positioning service;

S204, MSC/VLR sends a positioning request message to RAN/BSS, RAN/BSS, MS, and GPS obtain the precise location of the MS through a complex interaction process and positioning algorithm, and RAN/BSS reports the positioning result through a positioning report message to MSC/VLR;

S205, MSC/VLR converts the content of the positioning report message into a character stream of a coded mode recognizable by the MS, and when sending a mobility management information (MM Information) message to the MS, adopts the full name of the network name in the mobility management information ( Full name for network) information element or network name for short, send the location information of the location area or cell where the MS is located to the MS;

S206. For the MS that can support the location report message, the MSC/VLR may also directly send the location information of the location area or cell where the MS is located to the MS through the location report message;

It should be noted that multiple special service numbers can be preset to correspond to different types of positioning services. MSC/VLR can select different service numbers related to the MS according to the special service numbers corresponding to different positioning services dialed by mobile users. The location information is sent to the MS. For example, some special service numbers correspond to detailed and accurate location information, and some special service numbers correspond to simple location information.

S207, the location information of the location area or cell where the MS is located may have a lot of content, and a timer (such as 2 minutes) can be started after sending the location information, so that multiple mobility management information messages can be issued in batches , only one piece of location information is sent each time, for example, first use the full name of the screen to bring the local place name to the mobile phone, and carry the latitude and longitude of the region when sending again;

S208. In order to avoid always displaying the location information on the subsequent MS without the operator identification, after displaying all the location information and before the MS dials the special service number for the positioning service again, the MSC/VLR needs to The mobile subscriber IMSI obtains the operator identification (here also can realize by setting up the mode of data table on the exchange), and brings MS through the network name full name (Full name for network) cell of the mobility management information message, and restores on the MS screen as The operator's identification, when all the information is sent, the wireless resources will be released.
