Abstract
A private multiplexing cellular network for facilitating cellular communication for private mobile stations (MS's), public MS's, and hybrid MS's. The private multiplexing cellular network includes a multiplexing circuit coupled to its radio subsystem. The multiplexing circuit is in turn coupled to two A-interfaces: a private A-interface for coupling the private radio subsystem with the private Mobile Switching Center (MSC), and a public A-interface for coupling the private radio subsystem with the public MSC. Intelligence is also provided with the multiplexing circuit to decide, based on a number of parameters, whether the public MSC or the private MSC should handle a given service request.
Claims21
A private cellular communication system having a private mobile services switching center and a base station controller, said base station controller being configured to facilitate cellular communication for a plurality of private mobile stations and a plurality of public mobile stations associated with a public network having a public mobile services switching center, comprising:
- a multiplexing circuit coupled to said base station controller, said multiplexing circuit including a first interface circuit for coupling to said private mobile services switching center and a second interface circuit for coupling to said public mobile services switching center, said multiplexing circuit being configured to multiplex incoming and outgoing calls between said base station controller and one of said private mobile services switching center and said public mobile services switching center, wherein a call from one of said public mobile stations is handled through said public mobile services switching center and said base station controller via said multiplexing circuit when said one of said public mobile station is within a location area controlled by said base station controller, a call to one of said private mobile stations is handled through said private mobile services switching center and said base station controller via said multiplexing circuit when said one of said private mobile station is within a location area controlled by said base station controller.
A private cellular communication system having a private mobile services switching center and a base station controller, said base station controller being configured to facilitate cellular communication for a hybrid mobile station having a pubic telephone number and a private telephone number, said public telephone number being known to a public mobile services switching center in a public network, said private telephone number being known to said private mobile services switching center, comprising:
- a multiplexing circuit coupled to said base station controller, said multiplexing circuit including a first interface circuit for coupling to said private mobile services switching center and a second interface circuit for coupling to said public mobile services switching center,
- said multiplexing circuit being configured to multiplex incoming and outgoing calls between said base station controller and one of said private mobile services switching center and said public mobile services switching center,
- wherein a call from said hybrid mobile station, when made from within said location area controlled by said base station controller, is handled by said private mobile services switching center through said multiplexing circuit.
A multiplexing circuit configured for use in a private cellular communication system having a private mobile services switching center and a base station controller, said base station controller being configured to facilitate cellular communication for a hybrid mobile station having a pubic telephone number and a private telephone number, said public telephone number being known to a public mobile services switching center in a public network, said private telephone number being known to said private mobile services switching center, comprising:
- a first interface circuit configured for coupling to said private mobile services switching center;
- and
- a second interface circuit configured for coupling to said public mobile services switching center, said multiplexing circuit being configured to multiplex incoming and outgoing calls between said base station controller and one of said private mobile services switching center and said public mobile services switching center,
- wherein a call from said hybrid mobile station, when made from within said location area controlled by said base station controller, is multiplexed by said multiplexing circuit through said first interface circuit to said private mobile services switching center.
