Abstract

IP multimedia subsystem (IMS) provides the architectural framework for next generation networks. Presence is considered as the most important service of IMS. Currently, a user needs to subscribe for the presence service of the receiver before deciding whether to call that particular receiver or not. This mechanism increases the network traffic and may result in more delay in call setup. To handle this problem, we proposed a new presence enabled call setup model in this paper.

 

Key words: IP multimedia subsystem, presence, call setup.
