COMMUNICATIONS OPERATING SYSTEM AND METHOD THEREFOR

摘要

A common communications system (119) provides information regarding the availability of other local communication systems (111-117) within the common communications system coverage area to a generic, programmable subscriber unit (120). Geographical location information is then supplied to the common communications system (119) indicating position of the subscriber unit (120). The geographic information is used by either the common communication system (119) or subscriber unit (120) to provide information pertinent only to one or more local communications systems (111-117) that the subscriber unit (120) may select. The common communication system (119) or the subscriber unit (120) can also be used to selectively filter or extract information such that the information presented to the user is related to the geographical location. The subscriber unit (120) then selects one of the local communications systems (111-117) and receives enabling programming from that local communication system. The enabling programming permits the subscriber unit (120) to configure itself to operate on the selected communication system.
