Abstract
A cellular radio access network and a location updating in a cordless communications system, in a cellular radio access network (1), which is connected to one or more core networks (2, 3, 4, 5) or services (SP2 to SP5), 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 (2, 3, 4, 5) or services (SP2 to SP5) 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 (1) 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.
