ABSTRACT:
A method and apparatus for providing fixed telephony service in a mobile cellular telecommunications system is disclosed. In the invention a fixed subscriber is assigned a fixed area within a cellular system and may not move beyond the fixed area. The restriction on movement is accomplished by monitoring a location area identity (LAI), a timing advance (TA) value and a handover candidate cell list for the fixed subscriber. Monitored parameters are then compared with a fixed LAI, a fixed TA and a fixed handover candidate cell list to determine if the fixed subscriber has moved beyond the fixed area. If the comparison indicates movement has occurred, a violation signal is generated.
