Third party registration failure processing method and device for IMS (IP Multimedia Subsystem)

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 field of communications, and in particular, to a third-party registration failure processing method and device for IMS (IP Multimedia Subsystem, IP Multimedia Subsystem). Background technique [0002] As the high-level component of the next-generation network, the IMS system establishes a platform independent of the underlying bearer network, based on open SIP (Session Initiation Protocol) / IP, and a manageable and controllable platform for rich services. Its rich services are It is realized and provided by various application servers AS (Application Server). In the IMS communication network, the user wants to use the multimedia service provided by the network. The PU (Public User Identities) associated with the user UE (User Equipment) must be registered on the IMS core network and AS in advance, and The registration of the PUI on the AS is the third-party registration. In order to know the status change of the registe...
