Embodiment Construction

[0038] The following describes an HSS for each IMS subscriber maintaining a flexible data structure, a method of performing an implicit registration of an IRS sharing a given IMPU with another IRS, and serving an IMS subscriber and providing basic information to the HSS to derive access conditions Some preferred embodiments of the S-CSCF servers, which all cooperate to provide a more flexible data structure, where any IMPU (even a SIP URI type IMPU) can be shared by more than one IRS.

[0039] image 3The situation is shown where an IMS user can access the IMS 8 through a so-called fixed-mobile converged network, as already commented above when discussing the drawbacks addressed by the present invention. A fixed-mobile converged network (ie FMC network) may be understood as a network in which a user 91 may be connected with other users 92 via fixed or wired networks 61 - 62 or via a mobile, cellular or wireless network 63 . In the case of a wired connection by the user 91, fo...

Abstract

The present invention is aimed to provide a more flexible data structure where any IMPU, even those of the SIP URI type, may be shared by more than one IRS in order to simplify the registration of an IMPU for users of a Fixed-Mobile Convergent network. To this end, there is provided a flexible data structure wherein a number n of IMPUs of a user may be distributed in a number m of Implicit Registration Sets, wherein a given IMPU may be shared by more than one IRS, each IRS is associated with an access condition, and the explicit registration of said given IMPU under a given access condition triggers the implicit registration of those IMPUs in the IRS associated with said access condition, whilst the registration status of IMPUs in any other IRS remain unchanged.

Description

technical field [0001] The present invention generally relates to the implicit registration of the public user identity in the IP multimedia subsystem, and specifically relates to the case of application in fixed-mobile convergence. Background technique [0002] According to the 3GPP technical specification (ie 3GPP TS 23.228), the home network operator assigns one or more IMS private user identities to each user subscription of the IP Multimedia Subsystem (hereinafter referred to as IMS). Each IMS private user identity (hereinafter referred to as IMPI) is used for user registration in the IMS, and can be associated with one or more IMS public user identities. Each IMS public user identity (hereinafter referred to as IMPU) is used by a user to communicate with other users, and may be associated with a unique IMS service profile (hereinafter referred to as SP) and one or more IMPIs. In this regard, any SP may be associated with more than one IMPU, while each IMPU may only b...
