Location Conveyance in the IP Multimedia Subsystem
نویسندگان
چکیده
The 3rd Generation Partnership Project (3GPP) has proposed the IP Multimedia Subsystem (IMS) as a key element in the nextgeneration network (NGN) converged architecture supporting multimedia services. Extending the IMS towards provisioning support for location based services (LBS) will enable enhanced services and offer new revenues to the system. However, conveying location information in the IMS and connecting the IMS with a real positioning system are still open issues. This paper presents the design and implementation of an IMS Location Server (ILS) integrating IMS with a positioning system. From the IMS perspective, the ILS serves as a service enabler for LBS. Considerable work has been done by the IETF in the area of location information transport based on the Session Initiation Protocol (SIP). This paper proposes some improvements in this area. In order to demonstrate proof-ofconcept in enhancing IMS-based services, a Location-aware Push-to-Talk (LaPoC) prototype service has been developed. The service has been integrated and tested with the Ericsson Mobile Positioning System (MPS). The paper also gives the results of performance measurements including traffic load analysis and session establishment time.

Realizing Peer-to-Peer Location-Based Services in Mobile Networks
Current Location Based Services (LBS) in GSM/UMTS Networks rely on centralized Location Enabling Servers [8] for location information provisioning via the Gateway Mobile Location Center (GMLC) Le interface. In this Paper, we present a framework for providing Peer-to-Peer Location-Based Services using de-centralized location information management. The proposed solution relies on the future IP M...

The 3rd Generation Partnership Project (3GPP) will use the Session Initiation Protocol (SIP) as a session signalling protocol in the IP Multimedia Subsystem (IMS) of next generation UMTS systems. Certain nodes on the signalling layer have to process a large number of SIP messages. This paper introduces a concept for efficient SIP message routing and user assignment. The SIP Message Overflow Rou...
