Patent ID: 7738858

Claim:
A wireless messaging system comprising: a cellular radio communications network including a plurality of cellsites for routing cellular calls addressed to one or more subscriber numbers within a geographic area of coverage of said cellsites, wherein presence and location of individual active cellular 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; said network being configured such that calls placed to a subset of said cellular telephone numbers are routed through a preselected one or more of said cellsites without first verifying presence or location of a cellular handset assigned a telephone number within said subset; and a plurality of cellular radio communications receivers distributed within said geographic area of coverage each configured to accept cellular calls addressed by said cellsites to the 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, thereby enabling a cellular telephone call to be sent to multiple cellular receivers by originating a single cellular call.
