Abstract

A method and system for private wireless network communications is provided. A private wireless network controller is coupled to a Private Branch Exchange (PBX), a private base transceiver station, and a Public Switched Telephone Network (PSTN). The private base transceiver station is coupled to a wireless macro network. The private wireless network controller and private base transceiver station allow connection of interconnect and dispatch wireless calls, which originate on the private wireless network, to other mobile stations on the private wireless network, to terminals connected to the PBX, to mobile stations on wireless macro networks, and to terminals coupled to the PSTN.

Claims

1. A private communication network, comprising:

a private base transceiver station coupled to a plurality of antennas; and

a private network wireless controller coupled to a private branch exchange, a wireless macro network and the private base transceiver station, the private wireless network controller comprising

a dispatch call processor; and

an interconnect call processor.

2. The network of claim 1, wherein the private base transceiver station comprises a plurality of wireless radios coupled to the plurality of antennas.

3. The network of claim 2, wherein at least two of the plurality of wireless radios operate using different air interface protocols which are selected from the group consisting of integrated dispatch enhanced network (iDEN), code division multiple access (CDMA), time division multiple access (TDMA), global system for mobile communications (GSM), digital advanced mobile telephone service (D-AMPS), and Voice over Wireless Internet Protocol air interface protocols.

4. The network of claim 1, wherein the private wireless network controller receives a registration message from one of the plurality of antennas and determines whether a mobile station associated with the registration message is authorized to register with the private wireless network controller.

5. The network of claim 4, wherein the private wireless network controller comprises a location database, and wherein a mobile station is authorized to register with the private wireless network controller when an identification associated with the mobile station in the registration message is stored in the location database.

6. The network of claim 4, wherein the private wireless network controller comprises a location database, and wherein when an identification in the registration message is not stored in the location database, the private wireless network controller determines whether the mobile station is authorized to register using information from the wireless macro network.

7. The network of claim 1, wherein the private wireless network controller is coupled to a digital access cross-connect switch (DACS) in the wireless macro network.

8. The network of claim 1, wherein the private wireless network controller is coupled to a base site controller (BSC) in the wireless macro network.

9. The network of claim 1, further comprising:

a private network manager, wherein the private network manager provisions subscribers in the private network.

10. The network of claim 1, wherein the private wireless network is assigned its own location area.

11. A private wireless network comprising:

a private wireless network controller coupled to a private branch exchange and a wireless macro network; and

private base transceiver station coupled to the private wireless network controller, wherein the private wireless network controller is coupled to the wireless macro network as a base station of the wireless macro network.

12. The private wireless network of claim 11, wherein the private wireless network controller is coupled to a digital access cross-connect switch (DACS) of the wireless macro network.

13. The private wireless network of claim 12, wherein the private wireless network controller initiates and terminates dispatch calls between mobile stations in the wireless macro network and private wireless network using the connection to the DACS.

14. The private wireless network of claim 11, wherein the private wireless network controller is coupled to a base site controller (BSC) of the wireless macro network.

15. The private wireless network of claim 11, wherein the private wireless network controller comprises:

a transcoder for converting coding of voice communications originating in the private wireless network to coding compatible with a network associated with the private branch exchange.

16. The private wireless network of claim 11, comprising:

a location database including information regarding mobile stations associated with the private wireless network.

17. A method for registering a mobile station, the method comprising the acts of:

receiving, by a private wireless network, a registration request from a mobile station;

determining whether the mobile station is authorized to operate on the private wireless network;

forwarding the registration request to a wireless macro network; and

transmitting a registration response to the mobile station based on a response received from the wireless macro network.

18. The method of claim 17, wherein when the wireless macro network registration response rejects the mobile station'"'"'s registration request, the private wireless network modifies the wireless macro network registration response and transmits the modified registration response to the mobile station.

19. The method of claim 17, wherein when the wireless macro network registration response authorizes the mobile station'"'"'s registration request, the wireless macro network registration response is forwarded to the mobile station.

20. The method of claim 17, wherein when it is determined that the mobile station is not authorized to operate on the private wireless network, the method comprises the acts of:

determining that non-authorized mobile stations are allowed to operate on the private wireless network;

forwarding the registration request to the wireless macro network; and

forwarding, by the private wireless network, a registration response from the wireless macro network to the mobile station.
