Abstract

A communication system and method is provided for handling emergencies wherein public safety radios are used to directly communicate with normally incompatible radios used by organizations such as schools. The system includes a radio communication bridge that is selectively activated by emergency personnel to contact an organization undergoing an emergency. The bridge is activated via a TCP/IP command over an IP network or alternatively sent by a pre-programmed digital radio. Computer software or firmware at communication endpoints, emergency responder locations, and at an emergency call center facilitates functionality of the system to include emergency notifications, dissemination of information associated with a particular emergency, and the status of the system to include activation and deactivation of the radio bridge.

Claims

1. A communication system especially adapted for facilitating emergency communications between communication endpoints having incompatible radios operating on distinct frequencies, the endpoints including at least one public safety radio associated with a communication endpoint and at least one local radio associated with another communication endpoint, said system comprising:

at least one pre-programmed digital radio operating on a different channel or frequency than said at least one public safety radio and said at least one local radio;

a radio bridge for facilitating direct radio communications between said at least one public safety radio and said local radio, said radio bridge including hardware enabling connection between the radios, said bridge communicating with a communications server to receive activation and deactivation instructions sent from an authorized user, said instructions being sent as Internet Protocol (IP) packets over an IP communications network;

a digital radio module incorporated with said radio bridge, said module providing a capability to control said radio bridge by a radio frequency (RF) signal received from said at least one pre-programmed digital radio;

computer coded instructions associated with a computer processor of the system to selectively control and monitor the system to include (i) activation and deactivation of said radio bridge to prevent activation and deactivation control at said communication endpoint associated with the at least one local radio, and (ii) production of visual displays for a user that include an indication of whether a radio bridge has been activated or deactivated by said at least one pre-programmed digital radio.

2. The communication system, as claimed in claim 1, wherein:

said visual displays further include an activation or status screen showing a status of one or more selected communication endpoints and whether said endpoints have a radio bridge activated by the IP communications network, an RF network associated with said pre-programmed digital radio, or both said IP communication network or said RF network.

3. A method of communicating radio transmissions between communicants having respective radios, said method comprising:

providing a radio bridge for facilitating radio communications between at least one public safety radio and a local radio, said radio bridge including hardware enabling connection between the radios, said bridge communicating with a communications server to receive activation and deactivation instructions sent from an authorized user, said instructions being sent as Internet Protocol (IP) packets over a communications network of which said public safety radio and local radio are incorporated in;

providing a digital radio module incorporated with said radio bridge, said module providing a capability to alternatively control said radio bridge by a radio frequency (RF) signal received from at least one pre-programmed digital radio that operates on a different channel or frequency than said at least one local radio;

providing computer coded instructions to selectively control and monitor communications including activation and deactivation of said radio bridge and to prevent activation and deactivation control at a location associated with said local radio or said at least one pre-programmed digital radio; and

generating an indication on a user interface showing activation or deactivation of said radio bridge by said local radio or said at least one pre-programmed digital radio as associated with one or more communication endpoints.

4. A method, as claimed in claim 3, wherein:

said indication of activation or deactivation by said at least one pre-programmed digital radio includes an indication of whether the radio is a public safety digital radio or a private digital radio.

5. A method, as claimed in claim 3, wherein:

said indication of activation or deactivation by said at least one pre-programmed digital radio includes an indication of which communication endpoint is connected by said bridge or disconnected from said bridge.
