An unlicensed-radio access network is connected to a core network portion of a licensed cellular mobile network and includes a broadband network (302) with a plurality of access points (301) each defining a mini-cell and adapted to communicate with mobile stations located within a mini-cell over an unlicensed-radio interface. An access controller (303) is connected to the core network portion and to the broadband network. In accordance with the invention, the access controller (303) is associated with its own location area or areas in the licensed radio mobile network and comprises a database for storing the identification of mobile stations in association with at least one specific access point or broadband network address. This arrangement permits a mobile station to be locating within the access network in response to a paging signal from the core network without undue signalling load.
An unlicensed-radio access network connected to a core network portion (20) of a licensed mobile network, said unlicensed-radio access network (30) including an access controller (303) connected to said core network portion, a fixed broadband network (302) connected to said access controller and having a plurality of access points (301), each said access point defining a mini-cell coverage area (304) and supporting an unlicensed-radio interface permitting communication between mobile stations (1) located within a respective mini-cell and said access controller (303), characterised in that said access controller (303) is associated with one or more location areas in said licensed radio mobile network and comprises a database (3031) for storing the identification of mobile stations in association with address information of said mobile station on said fixed broadband network.
An access network as claimed in any previous claim, characterised in that said access network controller (303) is adapted to receive from a mobile station (1) a message registering identification data for said mobile station and to store said new identification data in said database in association with address information for said mobile station on said fixed broadband network (302).
An access network as claimed in any previous claim, characterised in that said mobile station identification data is the international mobile subscriber identity (IMSI).
An access network as claimed in any previous claim, characterised in that said address information is a network address of said access points (301) on said fixed broadband network (302).
An access network as claimed in any previous claim, characterised in that said access controller (303) is adapted to delete said identification data on receipt of a message from said access point (301) that said mobile station (1) is no longer communicating with said access point.
A method in an unlicensed-radio access network comprising a plurality of access points (301) adapted to communicate with mobile stations (1) over an unlicensed-radio interface and an access controller (303) connected to said access points and to a core network portion of a licensed-radio cellular network, said method including the steps of:
A method in an unlicensed-radio access network comprising a fixed broadband network with plurality of access points (301) and an access controller (303) connected to said fixed broadband network and to a core network portion of a licensed-radio cellular network and adapted to communicate with mobile stations (1) over an unlicensed-radio interface via said access points, said method including the steps of:
