Abstract

A system and method for providing a communication between public safety officials is disclosed. In a system of the invention, a communications network architecture includes a base transceiver station hub where the base transceiver station hub includes public safety network communications equipment and non-public safety network communications equipment. The architecture also includes a plurality of distributed antenna system (DAS) nodes and the base transceiver station hub is operatively coupled to the plurality of DAS nodes. In a method of the present invention, the method includes providing the public safety communication from the base transceiver station hub to one of a plurality of distributed antenna system (DAS) nodes by public safety network communications equipment included in the base transceiver station hub.

Claims

1. A cellular communications network architecture, comprising:

a first base transceiver station;

wherein the first base transceiver station includes public safety network communications equipment and non-public safety network communications equipment;

a plurality of distributed antenna system (DAS) nodes;

wherein the first base transceiver station is operatively coupled to the plurality of DAS nodes;

a second base transceiver station, wherein the second base transceiver station includes public safety network communications equipment and non-public safety network communications equipment;

wherein the public safety network communications equipment included in the first and second base transceiver stations provides communications over a frequency that is not available for use by commercial subscribers using the cellular communications network architecture;

wherein the first base transceiver station includes a first optical switch and wherein the second base transceiver station includes a second optical switch; and

a fiber optic communications link coupled between the first optical switch and the second optical switch, wherein the first base transceiver station is in communication with the second base transceiver station via the fiber optic communications link.

2. The cellular communications network architecture of claim 1, wherein the public safety network communications equipment supports communications between public safety officials and wherein the non-public safety network communications equipment supports communications between the commercial subscribers.

3. The cellular communications network architecture of claim 2, wherein the public safety officials are associated with an emergency response team.

4. The cellular communications network architecture of claim 2, further comprising a fiber optic link disposed between the first base transceiver station and the plurality of DAS nodes, and wherein the communications between the public safety officials and the communications between the commercial subscribers are both carried over the fiber optic link.

5. The cellular communications network architecture of claim 1, wherein the plurality of DAS nodes are optical repeaters.

6. The cellular communications network architecture of claim 1, further comprising:

a mobile switching office;

wherein the first base transceiver station is in communication with the mobile switching office via a first communications link;

and wherein the second base transceiver station is in communication with the mobile switching office via a second communications link.

7. The cellular communications network architecture of claim 1, wherein the first optical switch is physically located separate from the first base transceiver station and wherein the second optical switch is physically located separate from the second base transceiver station.

8. The cellular communications network architecture of claim 7, wherein the first optical switch is housed in a first enclosure and the first base transceiver station is housed in a second enclosure, and wherein the second optical switch is housed in a third enclosure and the second base transceiver station is housed in a fourth enclosure.

9. A method of providing a communication between public safety officials, comprising the steps of:

providing a first public safety communication from a first base transceiver station to one of a first plurality of distributed antenna system (DAS) nodes by public safety network communications equipment included in the first base transceiver station, wherein the first base transceiver station also includes non-public safety network communications equipment for supporting communications between subscribers to a commercial service provider network;

providing a second public safety communication from a second base transceiver station to one of a second plurality of distributed antenna system (DAS) nodes by public safety network communications equipment included in the second base transceiver station, wherein the second base transceiver station also includes non-public safety network communications equipment for supporting communications between subscribers to the commercial service provider network;

wherein the public safety network communications equipment included in the first and second base transceiver stations provides communications over a frequency that is not available for use by the subscribers to the commercial service provider network;

wherein the first base transceiver station includes a first optical switch and wherein the second base transceiver station includes a second optical switch; and

providing a communication from the first base transceiver station to the second base transceiver station via a fiber optic communications link coupled between the first optical switch and the second optical switch.

10. The method of claim 9, further comprising the step of providing the public safety communication from the one of the first plurality of DAS nodes to a mobile communications unit of a public safety official that is associated with an emergency response team.

11. The method of claim 9, wherein a fiber optic link is disposed between the first base transceiver station and the first plurality of DAS nodes, and wherein the first public safety communication and a communication between the subscribers to the commercial service provider network are both carried over the fiber optic link.

12. The method of claim 9, wherein the first optical switch is physically located separate from the first base transceiver station and wherein the second optical switch is physically located separate from the second base transceiver station.

13. The method of claim 9, wherein the first and second pluralities of DAS nodes are optical repeaters.

14. The method of claim 9, further comprising the step of providing a communication from the non-public safety network communications equipment included in the first base transceiver station to one of the first plurality of distributed antenna system (DAS) nodes.

15. The method of claim 12, wherein the first optical switch is housed in a first enclosure and the first base transceiver station is housed in a second enclosure, and wherein the second optical switch is housed in a third enclosure and the second base transceiver station is housed in a fourth enclosure.
