Embodiment Construction

[0058] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0059] figure 2 A flow chart showing a processing method according to a first embodiment of the present invention, the method includes the following steps:

[0060] Step 201, receiving the user status subscription request SUBSCRIBE sent by the subscriber, and querying whether the third-party registration of the user fails;

[0061] Step 202, if the user's third-party registration fails, send a failure response to the subscriber;

[0062] Step 203, the subscriber logs out the user according to the failure response.

[0063] After receiving the subscription request from the subscriber, this embodiment inquires whether the third-party registration of the user corresponding to the request fails. If it fails, the subscriber is notified to logout the user through a failure response. Since the failure response does not need to be initia...

Abstract

The invention provides third party registration failure processing method and device used for an IMS (IP Multimedia Subsystem). The method comprises the following steps of: receiving a user state subscription request sent by a subscriber, and inquiring whether the third party registration of a user fails or not; if the third party registration of the user fails, sending a failure response to the subscriber; and logging out the user by the subscriber according to the failure response. In the invention, the consistency of user data among equipment is effectively ensured, and the user data synchronism among equipment is realized, therefore, the problem of inconsistent user data among equipment, which is caused by incapability of establishing a subscription session because the third party registration of the user fails and incapability of informing the subscriber of logging out the user in the third party registration failure processing method in the related technology is prevented.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a third-party registration failure processing method and device for IMS (IP Multimedia Subsystem, IP Multimedia Subsystem). Background technique [0002] As a high-level component of the next-generation network, the IMS system establishes an open SIP (Session Initiation Protocol, Session Initiation Protocol) / IP-based and manageable and controllable platform to realize rich services. It is realized and provided by various application servers AS (Application Server). In the IMS communication network, if the user wants to use the multimedia service provided by the network, the PUI (Public User Identities) associated with the user UE (User Equipment, user equipment) must be registered in the IMS core network and the AS in advance. The registration of the PUI on the AS is a third-party registration. [0003] According to the description of the 3GPP 24.229 technical specification, ...
