Abstract

The invention discloses a method and device for updating the SIP conversation state and relates to the technical field of information. By the adoption of the method and device for updating the SIP conversation state, the information process of a network element can be simplified. The method comprises the steps that firstly, the network element receives a REGISTER message containing a field of a period of a conversation timer; secondly, the conversation timer is updated according to the REGISTER message and the conversation state is updated into the active conversation state. The method and device are suitable for updating the conversation state of the network element.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method and device for updating session status of Session Initiation Protocol (English full name: Session Initiation Protocol, English abbreviation: SIP). Background technique [0002] With the development of information technology, more and more users establish SIP sessions to communicate with other users. After the session is established, the network element needs to update the session timer periodically, so as to update the session state. Wherein, the session state includes a talking state and a hung up state. [0003] At present, a method for updating a SIP session state is to carry a session timer period field in a call request (English full name: REINVITE) message or an update (English full name: UPDATE) message sent to a network element, so that the network element The session timer is updated according to the session timer period field, so that the network...
