Embodiment Construction
[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0040] The invention discloses a method for controlling a session timer in a SIP network. The method is applied to a system including: an AS and a backward TU entity provided with a session timer; During the session, determine the duration of the session timer and send it to the backward TU entity; the backward TU entity reconfigures its own session timer according to the received duration of the session timer.
[0041] Among them, there may be one or more TU entities between the AS and the calling party, and these TU entities can be called the backward TU entities of the AS, including: the backward TU entities connected to the AS, and the backward TU entities connected The backward TU entity. In this case, when the AS returns the duration of the session timer, it first returns the duration of the session timer to the backward TU ent...
