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 (402, 404, 406) 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 if intrasystem capacity is not available. Mobiles are paged throughout the networked coverage area (111-113) starting in the coverage area (111-113) in which the mobile last registered. Mobiles automatically register in response to receipt of the overhead message train when moving between coverage areas (111-113).
