Method and system as well as apparatus for proxy call conversation control entity to execute administrative operation

Abstract

The present invention provides a method of executing management operation of an agent calling session control entity, and system and device. Under the realizing course of the embodiment of the invention, since the agent calling session control entity receives informing information of executing management operation transmitted by an operating maintenance center; the agent calling session control entity transmits information of reselecting agent calling session control entity, re-identifying authority or cancellation; the agent calling session control entity does not process application information of the user equipment, or returning using agent server response to the user equipment, so as to ensure the agent calling session control entity not being interrupted service under the course of executing management operation.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a proxy call session control entity execution management operation method, system and device. Background technique [0002] The IP Multimedia Subsystem (IMS) is a multimedia subsystem defined by the 3rd Generation Partnership Project (3GPP), which uses the Packet Domain (PS) as the bearer channel for its upper layer control signaling and media transmission, and introduces the Session Initiation Protocol ( SIP) as its service control protocol, utilizes the characteristics of the SIP protocol, which is simple, easy to expand, and convenient for media combination, and provides users with rich multimedia services by separating service control from bearer control. [0003] The main functional entities in IMS include Call Session Control Entity (CSCF) that controls functions such as user registration and sessions, Home Subscriber Server (HSS) that centrally manages user ...

AI Technical Summary

Problems solved by technology

[0006] In the process of implementing the present invention, the inventors found that in the prior art, when the P-CSCF or S-CSCF in the IMS network performs management operations, such as performing upgrade operations, or shutting down for maintenance operations, it is necessary to suspend services, which leads to When the P-CSCF or S-CSCF performs management operations, the services it provides will be interrupted, causing temporary paralysis of the network and affecting the normal use of user equipment
