A Secure Location Session Manager (SLSM) is an intelligent router for open mobile alliance (OMA) Secure User Plane Location (SUPL) Version 1.0 (and later) messages best implemented when multiple, geo-diverse SUPL servers are deployed in a distributed environment, such as an active-active redundant configuration within a wireless carrier's network. In a standalone option, the SLSM acts as a “middleman” for all SUPL positioning messages between a mobile device and a responsible SUPL server. In an embedded option, the SLSM resides within an existing server. The SLSM manages and stores session information for all pending and ongoing SUPL positioning sessions in internal tables for routing and load balancing purposes. The external interfaces of the SLSM consist of OMA ULP messages.

To this end, the real Identification (ID) of the target terminal is managed only by a Secure User Plane Location (SUPL) Location Center (SLC) with which the target terminal make a contract for positioning thereof, so that the real ID is prevented from being exposed to the outside. In this way, even when a plurality of SLCs that can be managed by different network operator performs positioning of a target terminal by using an SUPL Positioning Center (SPC) existing in an external network, the real ID of the target terminal is not transferred to the SPC, and thus the privacy of a user of the target terminal can be protected.

Disclosed is a system for providing a deferred service, the system including a Secure User Plane Location (SUPL) agent for requesting the deferred service according to a requirement of a client; and a SUPL Location Platform (SLP) for checking for allowance or denial of an event report for an event when the event occurs during the deferred service according to the request. In the system, allowance or denial of a user for a deferred service is reflected during the deferred service, and as a result, it is possible to prevent the violation of a user's privacy.

Systems and methods of sending a secure user plane location (SUPL) session initiation message from a location platform to a SUPL-enabled terminal are provided. When a network-based application has an internet protocol (IP) connection with the SUPL-enabled terminal using general packet radio service (GPRS) and needs location information regarding the SUPL-enabled terminal, the network-based application indicates an available GPRS session in mobile location protocol standard location immediate request. The location platform uses an application server hosting the network-based application to request starting a SUPL-enabled terminal-initiated location procedure. Alternatively, the location platform can determine whether a SUPL-enabled terminal has an active IP connection from an authentication, authorization, and accounting server. The IP address of the SUPL-enabled terminal is returned to the location platform, upon which a SUPL session initiation message is sent to an associated GPRS Gateway Support Node. User Datagram Protocol is utilized instead of Wireless Datagram Protocol.

A geographic cell identification (cell ID) database is updated on the fly as, for example, roaming user equipment (UE) reports its location during Assisted Global Positioning System (A-GPS) operations. The cell ID database relates network locations to corresponding geographic locations. The cell ID database is used to retrieve a corresponding geographic location in response to the network location at which the UE reports being located. If it is found that the cell ID database does not contain the network location reported by the UE, the geographic location of the UE can be estimated using information in the reported network location, such as Mobile Network Code, Mobile Country Code, Local Area Code and Cell ID. The geographic location can then be used to obtain A-GPS assistance data for the UE. Once assistance information has been provided to the UE and the UE has determined its geographic location, the cell ID database can be updated with the determined geographic location.

The present invention provides a method and system for implementing emergency location. The method comprises: a User Equipment (UE) initiating an emergency call, and initiating a SUPL position procedure to a security user plane location platform (SLP); and the SLP obtaining location information of the UE through the SUPL position procedure, and providing the location information of the UE to a location request function (LRF). Using the method, the SUPL position procedure is initiated by the UE when the emergency call is initiated and the SLP is not required to support the Session Initiation Protocol (SIP), thereby simplifying design of the SLP. Furthermore, it is clear to the UE that the UE is a qualified SET, so the location request initiated by the UE can certainly be responded correctly, thereby ensuring successful implementation of the emergency call process.
