Abstract

Adjacent cellular systems (101-103) are interconnected to form a network providing telephone coverage to mobiles located throughout their combined coverage areas (111-113). Each networked cellular system (101-103) includes base sites (412, 414, 416) located in cells (402, 404, 406) and a control terminal (420) coupled by data and voice lines to the base sites, a telephone central office (422) and the other cellular systems. Each base site (412, 414, 416) includes a base site controller 950, a scanning receiver 910, signalling transceiver 912 and up to eight voice channel transceivers (901-908). As mobiles move about the networked coverage area (111-113), intrasystem handoffs are provided between cells of the same cellular system, and intersystem handoffs are provided between border cells of adjacent cellular systems. Mobiles are paged throughout the networked coverage area (111-113) in the paging area (121-136) in which the mobile last registered. Registration parameters are updated by the control terminal (420) and base sites (412, 414, 416) and sent to mobiles in the overhead message train. Mobiles automatically register in response to receipt of the overhead message train when moving between paging areas (121-136) according to the flow charts of FIGS. 5 and 6.
