Problems solved by technology

[0022] In practical application, the above scheme has the following problems: HSS cannot realize the download of multiple public identities in different implicit registration groups of users through one registration
[0025] That is to say, a user can only receive a public ID in one implicit registration group through one registration. Similarly, if the implicit registration group changes, such as splitting and merging, HSS can only transfer the implicit registration group that contains the corresponding public ID. All groups log out, and wait for the user to initiate a new registration. CSCF can refresh the information when it downloads user data from HSS. During this logout process, the user call will be interrupted.

Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0050] UML model of the present invention such as Figure 4 shown, with figure 1 compared to figure 1 Add one more item to the structure: the implicit registration group number (Implict Group ID). The so-called implicit registration group number is a unique group identifier pre-allocated in the HSS for each implicit registration group.

[0051] When the implicit registration group is split or merged, the HSS only sends a modification message containing at least one piece of implicit registration group information to the CSCF through the Extensible Markup Language (XML) text, where each implicit The registration group information includes a group identifier and at least one public identifier.

[0052] When the CSCF receives the modification message, according t...

Abstract

The method comprises: the HSS adds a group ID for each anonymous registration group, and sends CSCF a message comprising either a group ID of anonymous registration group or a public ID of anonymous registration group; in term of received group ID and public ID the CSCF renews the public ID in local anonymous registration group having same group ID; the user data downloaded by CSCF from HSS can either include all public IDs of a anonymous registration group, or only includes the public ID required to modified and its modification way.

Description

technical field [0001] The invention relates to communication technology, in particular to a method for splitting or merging implicit registration groups in IMS sessions. Background technique [0002] At present, all countries in the world attach great importance to the development of the third generation mobile communication (The Third Generation, referred to as "3G") business, and invest a lot of manpower and material resources in research and development of related technologies and equipment. Among them, one of the three mainstream wireless interface standards of 3G is Wideband Code Division Multiple Access (WCDMA for short). [0003] An Internet Protocol (IP) multimedia subsystem in a WCDMA network defined according to the 3rd Generation Partnership Project (3GPP) R5 / R6 standard is an Internet protocol multimedia subsystem (IP Multimedia Subsystem, referred to as "IMS"). [0004] IMS is the target network for 3G mobile networks to realize packet voice and packet data, ...
