Claim:
A mobile telecommunications network including: a plurality of base station systems arranged to communicate with a mobile terminal over a predetermined licensed radio interface and switching centers connected to a plurality of said base station systems wherein each switching center and the base station systems connected thereto share a location area identity, said base station systems being adapted to communicate information indicative of said location area identity to a mobile terminal, wherein said network further includes at least two unlicensed-radio access networks, each comprising an access network controller connected to one of said switching centers, multiple access points adapted to communicate with said mobile terminal via an unlicensed-radio interface and a broadband network connecting said plurality of access points with said access network controllers and a lookup table mapping a location area identity with address information for an access network controller on said broadband network, and wherein each said access point is arranged to connect a mobile terminal with a default access network controller, said default access network controller being adapted to receive a request from said mobile terminal containing information indicative of a last location area received by said mobile terminal, to submit a request to said lookup table containing said location area information, to receive address information from said lookup table for an access network controller mapped to said location area in response to said request, and to transmit said address information to said mobile terminal via said access point, said address information enabling said mobile terminal to establish a connection with said addressed access network controller via said access point and said broadband network.
