Embodiment Construction

[0027] Certain embodiments of the present invention will be described below, by way of example, with reference to an exemplary architecture of a third generation (3G) mobile communication system. However, it should be understood that these embodiments may be applied to any suitable communication system.

[0028] Referring to Figure 1, there is shown an example of a network architecture in which the present invention may be embodied. In FIG. 1, an IP Multimedia Subsystem (IMS) 45 is provided to provide IP multimedia services to IP multimedia network subscribers.

[0029] As mentioned above, mobile communication systems can be relied upon to provide IP Multimedia (IM) functionality. A mobile communication system is generally arranged to serve a plurality of mobile user equipment (UE) via a radio interface between the user equipment and at least one base station of the communication system. A mobile communication system can be logically divided between a Radio Access Network (R...

Abstract

A method of registering users in a mobile communications system, the method comprising the steps of: storing in a user information store primary and secondary identifiers identifying a first serving controller; receiving a request from a serving controller, said request identifying that serving controller using primary and secondary identifiers; comparing the primary identifier in the user information store with the primary identifier in said request and, if there is a mismatch, comparing the secondary identifier in the user information store with the secondary identifier in said request wherein, when there is a mismatch between the secondary identifiers it is determined that the serving controller identified in the request is not the first serving controller; and when there is a match between the secondary identifiers it is determined that the serving controller identified in the request is the first serving controller.

Description

technical field [0001] The present invention relates to user registration in a communication system. Background technique [0002] Various distance communication systems currently in use support communication between two or more entities, such as user equipment and / or other nodes associated with the system. Such systems may include communications of voice, data, and multimedia data, for example. [0003] Communication systems that provide wireless communications to user terminals or other nodes are known. One example of wireless communication is a Public Land Mobile Network (PLMN). A PLMN is typically a cellular network in which a Base Transceiver Station (BTS) or similar access entity serves User Equipment (UE), eg Mobile Stations (MS), via a radio interface. Device operations required for communication are usually controlled by one or more control entities, which themselves may be interconnected. One or more gateway nodes are provided for connecting the PLMN to other n...
