Abstract
A system for servicing call establishment requests in a cellular telephone system on a priority basis is described. In this system, a base station receives a call establishment request either via an external MTSO (mobile telephone switch office) or PSTN (public telephone switch network), or internally from a call establishment request, broadcasted by a mobile unit associated with a first subscriber within the cell of interest. Both the base station and the mobile unit are located in a cell (i.e., the cell of interest) of the cellular telephone system. The base station determines whether it has a free channel to service the call establishment request. If the base station does not have a free channel to service the call establishment request, then a call processor determines a service priority level of the first subscriber. This service priority level is communicated to the base station. The base station processes the call establishment request in accordance with the service priority level of the first subscriber and service priority levels of second subscribers that are involved in telephone calls active in the cell.
