Method and apparatus for providing interswitch handover in personal communication services systems

THE SYSTEM OF THE INVENTION PROVIDES A METHOD FOR HANDLING INTERCOMMUNTATION TRANSFERS IN A PERSONAL COMMUNICATION SERVICES SYSTEM (PCS); THE METHOD OF THE INVENTION DESIGNATES THE ORIGINAL SWITCHING SYSTEM (2A) WHICH HOUSES THE RADIO PORT CONTROL UNIT (RPCU) (26A) THAT PROVIDES THE CALL FIRST AS ANCHORAGE SWITCH. THE ANCHOR SWITCH MAINTAINS THIS STATUS DURING THE DURATION OF THE CALL AND IS ALWAYS AT ITS DISPOSAL TO ADJUST THE THREE-WAY CONNECTION TO CARRY OUT THE TRANSFER OF THE INTER-SWITCH WITHOUT TAKING INTO ACCOUNT ANY NEW 2-SWITCH SYSTEMS (2) 26B, 26C) THAT SERVE THE CALL AS THE MOBILE STATION (34) MOVES THROUGH THE SYSTEM. THE NEW ADDITIONAL SWITCHING SYSTEMS THAT LODG THE NEW RPCUS ALWAYS COMMUNICATE WITH THE ANCHOR SWITCH (2A) AND THE CALL IS ALWAYS ROADED FROM THE ANCHOR SWITCH TO THE RETURN SWITCH TO THE SWITCHING SYSTEM. THE INTERMEDIATE SWITCHES (FOR EX. 2B) FALL FROM THE CONNECTION WHEN THE MOBILE STATION LEAVES THE AREAS (FOR EX. 36B) TO WHICH THEY PROVIDE SERVICE, ELIMINATING IN THIS WAY THE NEED TO MAINTAIN CONNECTIONS THROUGH PREVIOUS SWITCHING SYSTEMS.
