Abstract
A cellular radio access network and a location updating in a cordless communications system, in a cellular radio access network ( ), which is connected to one or more core networks ( ) or services (SP to SP ), each of them having a dedicated mobility management. In a cell, identities of all those location areas are broadcast to which said cell belongs. A subscriber terminal (MS) sends to the radio access network only one location updating message irrespective of how many core networks ( ) or services (SP to SP ) have a simultaneously changing location area at a handover from one cell to another. On the basis of the information contained in the location updating message, the network ( ) defines the core networks or services and location areas to which the location updating applies and sends a location updating message informing the new location of the subscriber or the subscriber terminal separately to each defined core network or service.
