Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] In this embodiment of the present invention, when the S-CSCF successfully registers the user's first application server and fails to perform the third registration on the second application server, the S-CSCF sets the user's registration status as unregistered, and Delete the user data related to the user in the S-CSCF. Afterwards, when the S-CSCF receives the user registration status subscription request from the registration status subscription entity, if the registration status of the user in the S-CSCF is unregistered, then S - The CSCF sends a message to the registration status subscrib...

Abstract

This invention discloses a process method for subscribed registration state including: when a S-CSCF entity receives a subscribing request of user registration state of a subscribing entity, if the registration state of said user in the S-CSCF is un-registered, then the S-CSCF sends information of deleting related data of said user to the registration state subscribing entity and informs the entity to set the registration state of said user un-registered and deletes related data of said user, at the same time, this invention also discloses a communication system and a device for realizing it. When S-CSCF registers to the first applied server successfully and fails in the third registration to the second applied server, it can timely delete the registration state and related user data kept in a node device.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method, system and device for processing subscription registration status. Background technique [0002] IP Multimedia Subsystem (IMS) is a multimedia service subsystem introduced in the R5 version of the third generation mobile communication standardization partnership project (3GPPR5, 3rd Generation Partnership Project). The initial goal is to access mobile packet terminals. Based on the ideas of separation, control and service separation, the IMS core network can access various types of Session Initiation Protocol (Session Initial Protocol, SIP) terminals, including early IMS terminals and fixed terminals, such as IAD terminals. IMS is composed of network entities that control multimedia sessions. In UMTS, IMS is the core for providing IP multimedia services. [0003] In the IMS domain, when the user registers successfully, the Serving-CSCF (Serving-CSCF, S...
