Topology verification process for controlling a personal communication services system

A topology verification process for a Personal Communication Services (PCS) system which includes a plurality of Cordless Fixed Parts (CFP)s each for transmitting and receiving signals therefrom, comprising the steps of:

• a) transmitting a test signal from a selected one of the plurality of CFPs;
• b) measuring the Received Signal Strength Indication (RSSI) of the transmitted test signal received by each of the other CFPs to provide a RSSI vector for each CFP;
• c) selecting other ones of the plurality of CFPs and repeating steps a) and b);
• d) mapping the spatial relationships of the CFPs relative to each other from the RSSI vector measurements;
• e) repeating steps a) to d) in response to selected criteria;
• and
• f) comparing the most recent mapped spatial relationships with the initial mapped spatial relationships, to detect changes in the topology of the CFPs in the system, which is highly indicative of a change in geographic area of operation of the PCS system.
