Abstract

SIP (Session Initiation Protocol) is a text-based protocol engineered for high data rate links. As a result, SIP messages size have not been optimised. This is problematic, particularly with the planned usage of this protocol in wireless handsets as part of 2.5G and 3G cellular networks. With low bit rate IP connectivity or signalling channel, the transmission delays for call setup and feature invocation are significant. In this paper, we propose a new approach called ”Smart Profile” where SIP messages are minimised in the access network for performance optimisation and completely reconstructed at the edge. The message reconstruction is based on SIP call profile that contains session attributes extracted from the user and terminal profiles. We discuss about Smart Profile implementation and focus on measuring its performance. Results and comparison with compression method show that Smart Profile solution is globally better.
