Presence in the IP multimedia subsystem
With an ever increasing penetration of Internet Protocol (IP) technologies, the wireless industry is evolving the mobile core network towards all-IP network. The IP Multimedia Subsystem (IMS) is a standardised Next Generation Network (NGN) architectural framework defined by the 3 Generation Partnership Project (3GPP) to bridge the gap between circuit-switched and packet-switched networks and co...
متن کاملLocation Conveyance in the IP Multimedia Subsystem
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 ...
متن کاملParlay PAM in 3GPP's IP-Multimedia Subsystem
The document will give a brief overview of the Presence and Availability -specification in general, protocols used in the IP Multimedia Subsystem namely SIP and Diameter and will show a possible mapping for PAM-methods to the underlying infrastructure. In addition it will describe the IMS infrastructure developed at Fraunhofer Fokus and the implementation of the PAM-server
متن کاملStrengthening Security of Ip Multimedia Subsystem
IP Multimedia Subsystem (IMS) is defined by 3GPP/3GPP2 and has become as a major part of the next-generation networks (NGN) service delivery platform. IMS provides convergence of two most successful communication paradigms – data networks (the Internet) and cellular networks on IP based infrastructure. Such platform allows an easy development of new value added and multimedia services. Open arc...
متن کاملNext Generation Network Service Architecture in the IP Multimedia Subsystem
The objective of this research work is to provide the IP Multimedia Subsystem of UMTS with a SIPbased mechanism for managing the interaction, composition and reuse of a limited number of standardized Service Capabilities in order to develop the Next Generation Network (NGN) services. The service invocation mechanism that we propose in this paper is extensible to deal with the interaction and co...
