  • Patent number: 6104928
    Abstract: The present invention provides geographically fixed receiver functionality for subscriber information which specifies the subscriber's identity in a mobile telecommunications system. This is achieved in accordance with the present invention by associating the Subscriber Identification Information (SII) with a fixed geographical reference point rather than with a particular device. In accordance with one embodiment of the present invention the access point lies outside the radio telecommunications system. In this embodiment, the control signals of the mobile system must be transmitted right up to the subscriber's premises. In a further preferred embodiment the access point lies in the radio telecommunications system. In the latter embodiment, the control signals of the mobile telecommunications system may be terminated in an access node which may be conveniently located in a wired base station.
