<p>The present invention describes an authentication method for use in a telecommunication system for providing Internet Protocol Multimedia services to a user using a terminal (Tl, T2, T3) of a customer premises multimedia equipment (EQUIP) and having a user identification (Ul, U2, U3, U4). The method comprises, in the event when the user identification is one of a first plurality of user identifications that are sharing a first fixed acces line, the steps of : - predefining in a storing means (MEM) for each one of a plurality of fixed acces lines (Ll, ..., L16) that comprises this first fixed acces line, an association between the one fixed acces line and a plurality of Internet Protocol Multimedia Subsystem profiles and providing thereby a plurality of associations, each one of the plurality of Internet Protocol Multimedia Subsystem profiles is related to one of a plurality of user identifications that are sharing the one fixed acces line. The plurality of associations comprises hereby a first plurality of associations between the first fixed access line and a first plurality of Internet Protocol Multimedia Subsystem Profiles, each being related to one of the first plurality of user identifications; and - transmitting by the terminal a service request (REQ) , that comprises the user identification U3, via the first fixed acces line,- and - determining with a processor (P), for the service request, the user identification and the first fixed access line; and - controlling with processor the plurality of associations, upon the presence of an association between the first fixed access line and an Internet Protocol Multimedia Subsystem Profile (P13) that is related to the user identification; and providing by the processor authentication (OK) for the user identification for at least one Internet Protocol Multimedia Subsystem service.</p> |
