Abstract
A WLAN terminal, system and method for providing a SUPL service, are discussed. According to an embodiment, the WLAN terminal includes a controller to establish an IP connection with a mobile communication network through interworking between the mobile communication network and a WLAN, and selectively perform a SUPL procedure with a location server of the mobile communication network through the IP connection in response to a request for location information of the WLAN terminal from the location server.
Claims8
A method of providing a SUPL (Secure User Plane Location) service by interworking between a mobile communication network and a wireless local area network (WLAN), the method comprising:
- receiving a location service request from a client;
- requesting routing information to a HSS/HLR (Home Subscriber Server/Home Location Register);
- receiving a routing information confirmation including the routing information from the HSS/HLR;
- sending a WLAN UE (user equipment) routing information inquiry to an AAA (Authentication/Authorization/Accounting) server;
- receiving a WLAN UE routing information response from the AAA server, wherein the WLAN UE routing information response includes WLAN UE address information;
- sending a SUPL initiation message to a WLAN UE through a WLAN AN (access network) using the WLAN UE address information received from the AAA server;
- receiving a SUPL positioning initiation message from the WLAN UE in order to start a SUPL positioning session with the WLAN UE;
- exchanging SUPL positioning messages with the WLAN UE for performing the SUPL positioning session to calculate a location of the WLAN UE;
- and
- sending a location service response that includes the calculated location of the WLAN UE to the client,
- wherein the WLAN UE is roaming with the WLAN via the mobile communication network.
A method of receiving a secure user plane location (SUPL) service through interworking between a mobile communication network and a wireless local area network (WLAN), the method performed by a WLAN UE (user equipment) and comprising:
- performing a connection setup procedure with an access point of the wireless local area network (WLAN);
- performing an authentication procedure with an AAA (Authentication/Authorization/Accounting) server of the mobile communication network;
- performing tunnel establishment with a packet data gateway (PDG) of the mobile communication network;
- and
- performing positioning procedures with a gateway mobile location center (GMLC) of the mobile communication network,
- the positioning procedures being performed via at least one secure user plane location (SUPL) positioning session comprising the steps of,
- receiving, through the access point of the WLAN, a SUPL initiation message from the GMLC that used WLAN UE address information received from the AAA server,
- sending a SUPL positioning initiation message to the GMLC in order to start a SUPL positioning session with the GMLC, and
- exchanging SUPL positioning messages with the GMLC for performing the SUPL positioning session to calculate a location of the WLAN UE,
- wherein the WLAN UE is roaming with the WLAN via the mobile communication network.
