发明名称 Wide area paging system having automatic service area log-in
摘要 A combination pager and cordless telephone (40) has a receiver (414) for receiving paging signals including a location identifier associated with a geographic location (202) of a paging controller transmitting the paging signals. A decoder (416) coupled to the receiver (414) decodes the paging signals to recover a page and the location identifier. A memory (422, 423) stores the page and the location identifier identifying the geographic location (202) of the transceiver (40). A message processor (606), coupled to the memory (423), determines when a new location identifier is received; and a controller (420) couples to a home paging controller (10) in response to the message processor (606) determining that the new location identifier has been received. A transmitter (440), coupled to the controller (420, 430), transmits the new location identifier to the home paging controller (10) for informing the home paging controller (10) that the transceiver (40) is located in the new geographic location (210) indicated by the location identifier.
