摘要： In a mobile communications system each radio unit (14,16) is associated with a respective base station (12) as its `home` base station; any radio unit can communicate with any base station in whose service area it is located. Each base station has a radio interface (20) for communication with radio units, a telephone interface (24) for connection to a telephone line, for example via a PABX (44), and a LAN interface (28) for connection to a local area network (40) to which all the base stations are coupled. Voice communications for a handset are always routed through the home base station for that handset, e.g. to another handset or to the PABX, irrespective of the identity of the base station in whose service area the handset is currently located.
