Hybrid public/private wireless network with seamless roaming
First Claim
1. A communications system connecting mobile subscriber devices to at least one of a PSTN and PBX network comprising:
- a plurality of network interface units (NIU) respectively communicatively coupled to one of a PSTN and a PBX having a predetermined coverage area;
at least one mobile subscriber device assigned to one of said network interface units designated a home network interface unit, said one mobile subscriber device receiving a port assignment through the home NIU from the PSTN or the PBX coupled thereto;
a plurality of wireless access subsystems (WAS) coupled respectively to the corresponding NIU and providing wireless connection between the corresponding NIU and a mobile subscriber device operating within the coverage area of the corresponding NIU; and
a programmable cross-connect device (ATC) connecting the plurality of network interface units and dynamically cross connecting calls between the home network interface unit of a mobile subscriber device and another network interface unit the coverage area of which is visited by said mobile subscriber device, said dynamic cross-connection being accomplished as part of a call origination and termination process.
