Abstract
In one embodiment, a private cellular system provides private cellular service and public cellular service using licensed frequency spectrum associated with a public land mobile network (PLMN). The system is configured to have a predetermined phone number that a subscriber who is using the public cellular service via the private cellular system and who is not registered to use the private cellular service provided by the system can call in order to register to use the private cellular service provided by the system and, in response thereto, the system captures a subscriber identity number associated with the subscriber and assigns a private telephone number to the subscriber that is used in connection with providing private cellular service. Another embodiment is directed to a method of enabling a prepaid hybrid subscriber to make a call using a private cellular system while outside of a coverage area associated with the private cellular system. Another embodiment is directed to a private cellular network comprising a plurality of private cellular systems to provide private cellular service and public cellular service using licensed frequency spectrum associated with a public land mobile network (PLMN). In that embodiment, a gateway function in each of the plurality of private cellular systems is configured to make the private cellular network appear, to the PLMN, as though it is implemented using only a single private cellular system.
