Abstract

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 of a customer premises multimedia equipment and having a user identification. 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 access line, the steps of: predefining in a storing means for each one of a plurality of fixed access lines that comprises this first fixed access line, an association between the one fixed access 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 access 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, that comprises the user identification U3, via the first fixed access line; and determining with a processor, for the service request, the user identification and the first fixed access line; and controlling with the processor the plurality of associations, upon the presence of an association between the first fixed access line and an Internet Protocol Multimedia Subsystem Profile that is related to the user identification; and providing by the processor authentication for the user identification for at least one Internet Protocol Multimedia Subsystem service.

Authentication method for use in a telecommunication system for providing Internet Protocol Multimedia services to a user using a terminal (T3) of a customer premises multimedia equipment (EQUIP) and having a user identification (U3), characterized in that in the event when said user identification being one of a first plurality of user identifications (U1, U2, U3, U4) sharing a first fixed access line (L1), said authentication method comprises the steps of:

predefining in a storing means (MEM) for each one of a plurality of fixed access lines (L1, L2, . . . , L16) that comprises said first fixed access line (L1), an association between said one fixed access line and a plurality of Internet Protocol Multimedia Subsystem profiles and providing thereby a plurality of associations, each one of said plurality of Internet Protocol Multimedia Subsystem profiles being related to one of a plurality of user identifications sharing said one fixed access line;
said plurality of associations comprising hereby a first plurality of associations between said first fixed access line (L1) and a first plurality of Internet Protocol Multimedia Subsystem Profiles (P13) each being related to one of said first plurality of user identifications (U1, U2, U3, U4);
and
transmitting by said terminal (T3) a service request (REQ) via said first fixed access line (L1), said service request (REQ) comprising said user identification (U3);
and
determining with a processor (P), for said service request (REQ), said user identification (U3) and said first fixed access line (L1);
and
controlling with said processor (P), said plurality of associations, upon the presence of an association between said first fixed access line (L1) and an Internet Protocol Multimedia Subsystem Profile (P13) being related to said user identification (U3);
and
providing by said processor (P) authentication (OK;
P13) for said user identification (U3) for at least one Internet Protocol Multimedia Subsystem service.

Authentication unit (AU) for use in a telecommunication system for providing. Internet Protocol Multimedia subsystems services to a user using a terminal (T3) of a customer premises multimedia equipment (EQUIP) and having a user identification (U3), characterized in that in the event when said user identification being one of a first plurality of user identifications (U1, U2, U3, U4) sharing a first fixed access line (L1) via which said authentication unit (AU) is coupled to said customer premises multimedia equipment (EQUIP) said authentication unit (AU) comprises:

a storing means (MEM) to predefine for each one of a plurality of fixed access lines (L1, L2, . . . , L16) that comprises said first fixed access line (L1), an association between said one fixed access line and a plurality of Internet Protocol Multimedia Subsystem Profiles and to provide thereby a plurality of associations, each one of said plurality of Internet Protocol Multimedia Subsystem Profiles being related to one of a plurality of user identifications sharing said one fixed access line, said storing means (MEM) comprises hereby a first plurality of associations between said first fixed access line (L1) and a first plurality of Internet Protocol Multimedia Subsystem Profiles (P13) each being related to one of said first plurality of user identifications (U1, U2, U3, U4);
and
a processor (P) to determine, for a service request (REQ) that comprises said user identification (U3) and being transmitted by said terminal (T3) via said first fixed access line (L1), said user identification (U3) and said first fixed access line (L1);
and to control said plurality of associations upon the presence of an association between said first fixed access line (L1) and an Internet Protocol Multimedia Subsystem Profile (P13) being related to said user identification (U3);
and to provide thereby authentication (OK;
P13) for said user identification (U3) for at least one Internet Protocol Multimedia Subsystem service.
