Embodiment Construction

[0062] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0063] figure 2 A flow chart showing a processing method according to a first embodiment of the present invention, the method includes the following steps:

[0064] Step 201, I-CSCF receives the user status subscription request SUBSCRIBE sent by the subscriber, and forwards the user status subscription request when the user's third-party registration fails through query;

[0065] Step 202, the S-CSCF establishes a subscription session with the subscriber according to the user status subscription request, and sends a logout notification request to the subscriber when the user's third-party registration fails;

[0066] Step 203, the subscriber requests to log out the user according to the logout notification.

[0067] The I-CSCF in this embodiment first receives the user status subscription request sent by the subscriber, and even i...

Abstract

The invention provides third party registration failure processing method and device for an IMS (IP Multimedia Subsystem). The method comprises the following steps of: receiving a user state subscription request transmitted by a subscribing party and establishing subscription conversation with the subscribing party when the third party registration failure of a user is obtained by inquiring; transmitting a cancellation notice request to the subscribing party; and canceling the user by the subscribing party according to the cancellation notice request. The method and the device ensure that a relevant network element establishes the subscription conversation with the subscribing party according to the normal subscription process when the third party registration of the user fails so as to transmit the cancellation notice request for indicating cancellation to the subscribing party, thereby effectively guaranteeing the consistency of user data among equipment and solving the problem of inconformity existing in the user data among the equipment caused by that the third party registration failure processing method in the relevant technology can not inform the subscribing party of canceling the user due to unavailable establishment of the subscription conversation by the third party registration failure of the user.

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. In order to know the status change of the registered user in time, both the UE and...
