ABSTRACT:
An arrangement for providing mobility in a communications system comprising a number of private branch exchanges to which a number of radio exchanges are connected over an interface and wherein a number of cordless extensions are connected to each private branch exchange over the radio exchanges. Between each private branch exchange and at least one radio exchange mobility serving means are arranged which in interworking with the private branch exchange emulate a radio exchange, thus providing cordless mobility between a number of radio exchanges.
