Patent ID: 8422995

Claim:
A cellular wireless messaging system adapted for addressing multiple cellular receivers by originating a single cellular call to a preassigned group broadcast number, comprising: a cellular radio communications network including a plurality of cellsites for routing cellular calls addressed to one or more subscriber cellular telephone numbers within a geographic area of coverage of said cellsites, wherein presence and location of individual active cellular telephone handsets is monitored relative to different ones of said cellsites such that a call directed to a particular cellular telephone number can be routed through an appropriate one of said cellsites within range of a handset corresponding to said particular cellular telephone number; a subset of said subscriber cellular telephone numbers reserved for assignment to broadcast subscribers of said network; and a plurality of cellular radio communications receivers distributed within said geographic area of coverage, each configured to automatically accept cellular calls addressed by said cellsites to a same one of said cellular telephone numbers within said subset such that multiple of said cellular radio receivers may each receive a particular cellular call addressed to a single cellular telephone number within said subset, each of said cellular radio communications receivers being associated with a two-way cellular telephone set thereby enabling a cellular telephone call to be sent to multiple said cellular receivers by originating a single cellular call while also tracking the presence of said cellular radio communications receivers present for census or billing purposes by way of said two way cellular telephone set such that each cellular receiver is capable of registering its presence with one or more of said cellsites.
