Abstract: A method, a system, and a network element for service processing after data of a network element is invalid or a network element fails are provided. When the service network element (1) receives the service request message from the network and initiated to a called end and the user data is invalid, the service network element (1) returns a data invalid message of the called end to the network. When a network element containing registration data of a user is abnormal and the registration data of the user is invalid, by using the present invention, the service unavailable time is shortened, and user services can be recovered rapidly.

Abstract: The present invention discloses a method for realizing user identity association, the method comprising: setting an equivalent behavior user identifier in a Home Subscription Server (HSS); associating IMS Public User Identities (IMPUs) with the equivalent behavior through the set equivalent behavior user identifier. The present invention also discloses a system and a device realizing user identity association. According to the embodiments of the present invention, the association of the IMPUs with the set equivalent behavior is realized, which improves the user experiences.

Abstract: The present disclosure discloses a method, an apparatus and a system for managing user access to a network. The method includes: carrying, by a mobile management apparatus, in a location update request a radio access type currently used by a user; and determining, by an access restriction management apparatus in accordance with the received radio access type currently used by the user and access restriction subscription data of the user stored therein, whether the user is allowed to get access to the network through the currently used access type, and, when it is determined the access is not allowed, directly returning a location update failure response to the mobile management apparatus, thereby avoiding unnecessary signaling load between the mobile management apparatus and one of an HLR and an HSS.
