Cellular communication system
First Claim
1. A cellular private branch exchange network for facilitating cellular communication for a first plurality of mobile station units, comprising:
- a first base station subsystem for communicating with a first and a second mobile station unit of said first plurality of mobile station units on respectively a first and a second cellular bearer data channel, wherein the first base station subsystem is configured to provide a first cross-connect node capable of cross-connecting said first cellular bearer data channel with said second cellular bearer data channel for calls between said first and second mobile station units; and
a cellular private branch exchange subsystem coupled to said first base station subsystem and to a public network, said cellular private branch exchange subsystem comprising;
a private mobile-services switching center for providing mobility management for said first plurality of mobile station units, said private mobile-services switching center configured to provide a second cross-connect node capable of cross-connecting said first cellular bearer data channel with said second cellular bearer data channel for calls between said first and said second mobile station units;
a private registry coupled to said private mobile-services switching center, said private registry storing subscriber information pertaining to said first plurality of mobile station units; and
a private branch exchange block coupled to the private mobile-services switching center and private registry, the private branch exchange block configured determine whether to cross-connect the first cellular bearer data channel with the second cellular bearer data channel for calls between the first and second mobile stations at the first node in the base station subsystem, the second node in the private mobile service switching center, or in a public switching center in the public network.
