Abstract

The Session Timer mechanism for Session Initiation Protocol (SIP) has been proposed to track the states of the communicating sessions for proxy servers. Upon the occurrence of the session failure (e.g., radio link disconnection), the proxy server can quickly release the resources allocated for the failed session by using SIP Session Timer. Based on SIP Session Timer, we propose a dynamic session refreshing approach to adjust the session timer depending on the conditions of radio links for wireless VoIP subscribers. The study indicates that with our dynamic session refreshing approach, the session failure can be efficiently detected without the considerable increase of signaling traffic.
