Abstract

A method and apparatus are provided, for accessing a data-capture device in a different domain, by public safety wireless communications equipment, for the purpose of obtaining information at an incident. A dispatch controller of a public safety wireless communications system receives an access token from a server of a non-public-safety network, when an incident occurs. The token allows access to a data-capture device, and is associated with the incident. The dispatch controller sends the token to the data-capture device, receives a data stream, and forwards the data stream to a public safety wireless communication device. The public safety wireless communication device may itself discover and access the data-capture device, and may receive the data stream directly from the data-capture device. The public safety wireless communication device may forward the data stream and/or the access token to other public safety wireless communication devices.

Claims

1. A method of accessing a data-capture device by public safety wireless communications equipment during an incident, the method comprising:

a public safety wireless communication device, at a time of an incident;

receiving, from a dispatch controller of a public safety wireless communications system, an incident identification;

identifying a non-public safety data-capture device at a location of an incident, the non-public safety data-capture device belonging to a domain;

sending an access request including the incident identification to a server of a non-public safety network, the server of the non-public safety network belonging to the domain;

authenticating to the server of the non-public safety network via an identification management server;

receiving, directly from the server of the non-public-safety network, a token generated by the server of the non-public safety network, the token including the incident identification and allowing secure access to the non-public-safety data-capture device at the location of the incident;

sending the token to the non-public-safety data-capture device;

receiving a data stream directly from the non-public-safety data-capture device and/or from the server of the non-public safety network; and

sending the token and/or streaming the data stream to one or more other public safety wireless communication devices of a communication group, the public safety wireless communication device being a member of the communication group.

2. The method of claim 1, further comprising:

when the public safety wireless communication device sends the token to the one or more other public safety wireless communication devices of the communication group, at least one of the other public safety wireless communication devices of the communication group;

sending the token to the non-public-safety data-capture device; and

receiving a data stream directly from the data-capture device and/or the server of the of the non-public safety network.

3. The method of claim 1, further comprising:

the one or more other public safety wireless communication devices of the communication group authenticating with the public safety wireless communication device based on the incident identification of the token, prior to the public safety wireless communication device streaming the data stream to the one or more other public safety wireless communication devices of the communication group.

4. The method of claim 1, further comprising:

one or more wireless communication devices that do not form part of the communication group;

authenticating with the public safety wireless communication device; and

receiving the data stream from the public safety wireless communication device.

5. A method of accessing a data-capture device by public safety wireless communications equipment during an incident, the method comprising:

a public safety wireless communication device, at a time of an incident;

receiving, from a dispatch controller of a public safety wireless communications system, an incident identification;

identifying a non-public-safety data-capture device at a location of the incident;

receiving, directly from a server of a non-public-safety network, a token generated by the server of the non-public safety network, the token including the incident identification and allowing secure access to the non-public-safety data-capture device;

sending the token to the dispatch controller of a public safety wireless communications system;

the dispatch controller of the public safety wireless communications system;

forwarding the token to one or more other public safety wireless communication devices that are public safety wireless communication devices of assigned first responders, or based on the incident identification of the token;

or

sending the token to the server of the non-public-safety network, receiving a data stream directly from the server of the non-public-safety network, and forwarding the data stream to the one or more other public safety wireless communication devices.

6. An apparatus for of accessing a data-capture device during an incident, the apparatus comprising:

a public safety wireless communication device comprising;

a processor that is configured to;

receive, from a dispatch controller of a public safety wireless communications system, an incident identification;

identify a non-public safety data-capture device at a location of an incident, the non-public safety data-capture device belonging to a domain;

send an access request including an incident identification to a server of a non-public safety network, the server of the non-public safety network belonging to the domain;

authenticating to the server of the non-public safety network via an identification management server;

receive, directly from the server of the non-public-safety network, a token generated by the server of the non-public safety network, the token including the incident identification and allowing secure access to the non-public-safety data-capture device at the location of the incident;

send the token to the non-public-safety data-capture device;

receive a data stream directly from the non-public-safety data-capture device and/or from the server of the non-public safety network; and

send the token and/or streaming the data stream to one or more other public safety wireless communication devices of a communication group, the public safety wireless communication device being a member of the communication group.

7. The apparatus of claim 6, wherein the processor further is configured to:

when the public safety wireless communication device sends the token to the one or more other public safety wireless communication devices of the communication group, at least one of the other public safety wireless communication devices of the communication group;

send the token to the non-public-safety data-capture device; and

receive a data stream directly from the data-capture device and/or the server of the of the non-public safety network.

8. The apparatus of claim 6, wherein the processor further is configured to:

authenticate the one or more other public safety wireless communication devices of the communication group, prior to the public safety wireless communication device streaming the data stream to the one or more other public safety wireless communication devices of the communication group.

9. The apparatus of claim 6, wherein the processor further is configured to:

authenticate one or more wireless communication devices that do not form part of the communication group; and

convey the data stream to the one or more wireless communication devices that do not form part of the communication group.
