Embodiment Construction

[0028] see now figure 1 , which shows a positioning system for a mobile multi-network environment of the present invention. The location service system includes: a plurality of GMLCs (Gateway Mobile Location Center) 202 and 212, clients 201 and 211 connect to GMLCs 202 and 212 respectively to send their location requests. GMLC 202 is connected to SGSN / MSC (Serving GPRS Support Node / Mobile Services Switching Center) 203 and 213 . GMLC212 is also connected to SGSN / MCS203 and 213. In addition, when a location request is for a UE terminal of an external network, two GMLCs are interconnected with each other to send the location request to another GMLC. RANs 204 and 214 are connected to SGSN / MSCs 203 and 213 respectively. UE terminals 205 and 215 are connected to RANs 204 and 214 respectively via wireless links. For simplicity, only one RAN is shown connected to each SGSN / MSC as representative of multiple RANs managed by the associated SGSN / MSC. The identification data of the S...

Abstract

In a location system, gateways maintain privacy settings of mobile terminals. On receiving a location request from a client terminal, each gateway determines which of the gateways maintains the privacy settings of a target mobile terminal specified in the request, and transmits the location request to a gateway if the latter maintains the privacy settings of the specified target mobile terminal. The gateway performs a first privacy check on a location request received either from the client terminal or from other gateway using the privacy settings of the target mobile terminal, transmits the request to a positioning system to obtain a measurement result indicating the location of the target mobile terminal if the request conforms to the privacy settings, and performs a second privacy check on the measurement result using the privacy settings. A result of the second privacy check is then communicated to the client terminal.

Description

technical field [0001] The present invention generally relates to a mobile communication system, and in particular to a positioning system that provides information services about the positioning of user equipment (UE) terminals to users. Background technique [0002] As a value-added function of mobile communication services, location information service is an important subject of enhancing mobile terminal operation functions currently being studied by the Third Generation Partnership Project (3GPP). 3GPP Technical Specification 23.271 v.5.1.0, "Functional Level 2 Description of LCS" published in December 2001 (hereinafter referred to as Document 1), is a current standard that clearly specifies the details of location information services. Since the location information of a mobile terminal station is very sensitive to the user and must be protected, the mobile communication network is equipped with an advanced privacy protection function that restricts access according to ...
