Transport of LCS-related messages for LTE access
First Claim
1. A method of obtaining location services, comprising:
- communicating with a Radio Access Network (RAN) via Long Term Evolution (LTE) access by a User Equipment (UE);
receiving a first Non-Access Stratum (NAS) message from a Mobility Management Entity (MME) to transport a first message for location services for the UE; and
sending a second NAS message to the MME to transport a second message for location services for the UE, wherein each of the first NAS message and the second NAS message comprises a routing identifier (ID) for associating the first NAS message, the second NAS message, the first message for location services, and the second message for location services with a location session between the MME and a location center to provide the location services, wherein the routing ID is a correlation ID that identifies the location session, and wherein the routing ID is maintained by the MME for the UE.

Abstract
Techniques for transporting messages for location services (LCS) are described. A Mobility Management Entity (MME) may have a location session with an Evolved Serving Mobile Location Center (E-SMLC) to provide location services for a User Equipment (UE). The UE may exchange LCS-related messages with the E-SMLC to obtain location services. In an aspect, LCS-related messages exchanged between the UE and the E-SMLC may be encapsulated in Non-Access Stratum (NAS) messages and transported via the MME and a base station. In another aspect, a routing identifier (ID) may be used to associate messages exchanged between the UE and the MME with the location session between the MME and the E-SMLC for the UE. Each NAS message exchanged between the MME and the UE may include the routing ID, which may enable the MME to associate each NAS message from the UE with the location session between the MME and the E-SMLC.
