  • Patent number: 6112097
    Abstract: The present invention relates to a flexible location area management scheme and arrangement for the reducing of signaling in a cordless communications network, which network comprises central control fixed parts (CCFP), each interconnected to radio fixed parts (RFP), particularly in a DECT based PSTN/CTM network. The invention comprises the steps of associating each of the radio fixed parts (RFP) with a radio fixed part identity (RFPI) in such a way that at least to a certain degree neighboring radio fixed parts (RFP) will have radio fixed part identities (RFPI) with consecutive numbers (x . . . x00, x . . . x01, x . . . x10, x . . . x11), defining the location area configuration of the cordless communications network by assigning a location area level (LAL) to each radio fixed part (RFP), and redefining the location area configuration of the cordless communications network by changing the location area level (LAL) to a different level in at least two radio fixed parts (RFP).
