Method and device for controlling session refreshing duration

Abstract

The invention relates to the field of wireless communication, in particular to a method and a device for controlling a session refreshing duration, and solves a problem that an existing session refreshing mechanism cannot reflect the difference of different session processes of different clients. The method comprises the following steps that an S-CSCF acquires a session refreshing duration presetfor each session process of each client; after the S-CSCF acquires an expected session refreshing duration set for the current session process from the client, the S-CSCF determines the session refreshing duration corresponding to the current session process of the client based on a user identifier corresponding to the client and a process identifier corresponding to the current session process; and the S-CSCF takes a smaller one in the two session refreshing durations as a target session refreshing duration of the client to be sent to the client, so that the S-CSCF can configure different session refreshing durations for different session processes of different clients, and thus the actual requirements of different session processes of the client can be met, system traffic parameters areflexibly distributed, and the system load is reduced.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for controlling session refresh duration. Background technique [0002] Session Initiation Protocol (Session Initiation Protocol, SIP) is a multimedia communication protocol, is a text-based application layer control protocol, used to create, modify and release the session of one or more participants, widely used in IP multimedia sub System (IP Multimedia Subsystem, IMS), commonly known as telephone service. [0003] As we all know, the service quality of telephone services (such as audio and video calls, video conferencing, etc.) is related to the signal. For some harsh environments (such as coal mining sites, remote mountainous areas, etc.), the telephone service is often interrupted due to signal loss. [0004] For example, in the roadway of the mining 4G Dongxia Coal Mine Project site, the communication link is very easy to be interrupted. If the on-...
