ROAMING DETERMINING METHOD FOR ACQUIRING ROANMING SUBSCRIBER POSITION INFORMATION ON OMA H-SLP TYPE BASED ON GPS {ROAMING DETERMINING METHOD FOR ACQUIRING ROANMING SUBSCRIBER POSITION INFORMATION ON OMA H-SLP TYPE BASED ON GPS}

The present invention relates to a roaming determination method, and more particularly, to a roaming determination method and system for obtaining roaming subscriber position information of GPS-based OMA H-SLP method for reducing the load on GLMC.

Location Base Service (LBS) refers to a service that identifies a location of a person or a thing and provides additional information related to the location based on a mobile communication terminal such as a mobile phone or a PDA. In order to provide a location based service, a process of determining a location of a mobile communication terminal must be preceded.

Positioning techniques for determining the location of a mobile communication terminal for providing location-based services are broadly classified into cell-based technologies using base station reception signals of mobile communication networks and GPS-based technologies using GPS receivers. Cell-based technology has a big error range, so GPS-based technology (eg, A-GPS (Assisted GPS)) that links a GPS (Global Positioning System) system and a mobile communication core network to provide more accurate location-based services This is becoming commonplace.

However, GPS-based technology requires a separate facility investment in addition to the core network for mobile communication services.

Meanwhile, in order to provide a smooth location-based service, location information of a mobile communication terminal is provided regardless of whether the mobile communication terminal is in a home network area or a roaming network or visited network area. It should be possible.

However, there may be a special case of exchanging network information including mutual BSA information through mutual alliances between domestic and overseas mobile service providers, but in a more general communication environment in which roaming network base station information is not disclosed. As a premise, a mobile communication user may visit a foreign country and use a roaming service in a service area of an overseas mobile communication provider. In this case, since the base station information (BSA, Base Station Almanac) in the roaming network is not disclosed to the domestic mobile service provider managing the home network, there is a problem in that the location of the mobile communication terminal cannot be determined.

In order to solve this problem, by providing a location-based service for the subscriber terminal roamed to a roaming network in a communication environment in which the base station information is not provided by using the GMLC according to the applicant's previous application (Application No. 2009-0098143) There has been provided a method of locating the risk.

However, according to the applicant's previous application (Application No. 2009-0098143), GMLC requests the roaming location information of the target subscriber to GMLC without regard to domestic / international (roaming) for the GPS roaming service subscriber. Thus, a problem occurs that an unnecessary procedure occurs.

In more detail, in the case of the OMA SUPL roaming H-SLP scheme, the OMA RLP protocol is used to obtain an initial position for the target terminal. Roaming location information of target subscriber for location information is needed through OMA RLP. The existing GMLC method roams target subscriber without any distinction between domestic and foreign (roaming) for all GPS roaming service subscribers. There was a problem in that an unnecessary flow procedure was generated by requesting location information, which caused a load on the Gateway Mobile Location Center (GMLC). More specifically, as shown in Figure 1, the roaming terminal (UE, 800) transmits a service request to the service server 100 (S10). Thereafter, the service server 100 receiving the roaming request transmits the location request to the LBSP 200 (S11), and the LBSP 200 transmits the location request to the LM 300 (S12). Accordingly, even though the roaming processing rate is only about 10% for the GPS roaming service subscriber, the LM 300 can use the GPS Roam Request (MSID), which is the roaming location information of the target subscriber, regardless of domestic / international (roaming). ) To the GMLC 500 (S13), an unnecessary procedure or a flow procedure occurs, which causes the GMLC 500 to give more load than necessary. On the other hand, the process of steps S15 to S33 to omit the description thereof in order to more clearly highlight the conventional problem.

Accordingly, in order to solve the problem, a technical development for reducing the load on the GMLC is required in the related art.

The service server 100 receiving the roaming request transmits a location request to the Location Base Service Platform (LBSP) 200 including MCC (Mobile Country Code) and MNC (Moblie Network Code) information (S41). Here, the LBSP 200 is a system that performs a function with the Open API Platform.

When the authentication process of the roaming terminal 800 is completed, the LBSP 200 transmits a location request to the LM 300 including a mobile country code (MCC) and a mobile network code (MNC) (S42). Here, the LM 300 is a Location Client Service (LCS) client that performs a location request to a location manager.

The LM 300 determines whether the terminal 800 roams to the outside by using the Mobile Country Code (MCC) and the Mobile Network Code (MNC) included in the location request message received from the LBSP 200. If it is determined that it is roaming, the GPS Roam Reqest (MDN, IMSI), which is a roaming information request including a Mobile Switching Center (MSC) and a Serving GPRS Support Node (SGSN) in an area where the roaming terminal 800 roams, is used by the GMLC 500.
