Abstract
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.
