Cellular mobile networks can include unlicensed-radio access networks, which comprise access point controllers (303) connected via a fixed broadband network (302) to access points (301) that communicate with mobile stations (1) via unlicensed radio. The access points are connected to the broadband network from any location by the subscriber. In order to alleviate the configuration required to enable handover, each access point controller is assigned to a location area defined in the conventional cellular network. A mobile station entering the mini-cell of an access point uses an indication of the location area for the last cell of a conventional network it communicated with to query a lookup table (which may be a DNS server) for the address of an access controller assigned to this location area. The mobile station then establishes a connection with the access controller to enable communication with a core network portion of the conventional network.
