Patent ID: 7900039

Claim:
A method of managing a Transport Layer Security (TLS) session in a Secure User Plane Location (SUPL)-based positioning system, the method comprising: setting, by a Home SUPL Location Platform (H-SLP), the TLS session with a terminal, during which the H-SLP receives secret information from the terminal to be used for an encryption and an integrity check with respect to a new TLS connection of the TLS session; receiving, by the H-SLP, a SUPL START message from the terminal; determining, by the H-SLP, whether the terminal roams to a Visited SLP (V-SLP) based on routing information, wherein the V-SLP includes a Visited SUPL Location Center (V-SLC) and a Visited SUPL Positioning Center (V-SPC); transferring, by the H-SLP to the V-SLC, TLS session information related to the set TLS session and the SUPL START message if it is determined that the terminal roams to the V-SLP; transmitting, by the V-SLC to the V-SPC, the TLS session information; and using, by the V-SPC, the TLS session information to set the new TLS connection with the terminal without exchanging further information for the encryption and the integrity check between the terminal and the V-SPC.
