Problems solved by technology

[0024] From the above analysis, it can be seen that the service behavior of the CS domain needs to be controlled in real time according to the registration status of the IMS centralized service. When the user is in the ICS registered state, the IMS provides the service, and when the user is in the ICS unregistered state, the CS domain provides the service , which can effectively improve the service availability of the IMS centralized service mode; and the existing ICS registration mechanism cannot meet this demand

Embodiment Construction

[0050] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0051] figure 2 The process of user data update for the IMS centralized service of the present invention:

[0052] (1) The HSS receives a user data download trigger event and prepares to download user data to the CS domain.

[0053] The trigger event that makes the HSS prepare to download user data to the CS domain includes one or a combination of the following situations: UE performs CS domain attachment, UE performs CS domain location update, user data corresponding to the current IMS centralized service registration status changes, IMS The centralized control service subscription changes, and the HSS judges that the registration status of the IMS centralized service changes.

[0054] Wherein, the HSS judges that the registration state of the IMS centralized service changes, including: changing from the "registered" state to the "...

Abstract

The invention discloses a method for updating user data in IP multi-media subsystem centralized transaction, which has the characteristics that: an attributive user server receives user data and loads a trigger event; the attributive user server checks registered state in an user IP multi-media subsystem centralized transaction; the attributive user server loads corresponding user data for circuit domain according to the registered state in the user IP multi-media subsystem centralized transaction. The invention achieves that transaction is provided by the IP multi-media subsystem centralized transaction under the condition of the registered sate in the IP multi-media subsystem centralized transaction, and transaction effect is provided by CS domain under the condition of unregistered state, then the transaction demand is meet, availability of IMS centralized transaction is promoted.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a method for updating circuit domain user data of IP multimedia subsystem centralized services. Background technique [0002] IP (Internet Protocol, referred to as IP) multimedia subsystem (IPMultimedia Core Network Subsystem, referred to as IMS) is an IP-based network architecture proposed by the 3rd Generation Partnership Project (3rdGeneration Partnership Project, referred to as 3GPP). It builds an open and flexible business environment, supports multimedia applications, and provides users with rich multimedia services. [0003] IMS is an IP-based telecommunications network architecture and has nothing to do with access technology. In addition to providing services for packet access networks such as GPRS (General Packet Radio Service) and WLAN (Wireless Local Area Network, wireless local area network), it also provides It can provide services for mobile cellu...
