Abstract

A method and apparatus for interoperability between packet-switched systems is described. The method includes the steps of: establishing (810) a connection with at least one packet-switched apparatus; generating (820) at least one communication frame at a session layer including a payload field for carrying a payload and a signal field for carrying a control signal; and transmitting (830) the at least one communication frame to the at least one packet-switched apparatus.

Claims

1. A method for interoperability between packet-switched apparatus comprising the steps of:

establishing a connection with at least one packet-switched apparatus;

generating at least one communication frame at a session layer comprising a payload field for carrying a payload and a signal field for carrying a control signal; and

transmitting the at least one communication frame to the at least one packet-switched apparatus.

2. The method of claim 1, wherein the at least one communication frame is directly transmitted to the at least one packet-switched apparatus.

3. The method of claim 1, wherein the payload comprises one of audio, video and data.

4. The method of claim 1, wherein the control signal is a radio control signal.

5. The method of claim 4, wherein the radio control signal is a push-to-talk (PTT) signal.

6. The method of claim 1, wherein the connection is establish using a session layer protocol.

7. The method of claim 6, wherein the session layer protocol is a Session Initiation Protocol.

8. The method claim 1, wherein the connection is established by a user of a dispatch apparatus and the connection is between the at least one packet-switched apparatus and one of the dispatch apparatus and a radio apparatus.

9. The method of claim 1 further comprising terminating the connection.

10. A packet-switched apparatus comprising:

a processing device for executing process steps; and

a storage device coupled to the processing device for storing a set process steps executable by the processing device, the process steps comprising;

establishing a connection with at least one other packet-switched apparatus;

generating at least one communication frame comprising a payload field for carrying a payload and a signal field for carrying a control signal; and

causing the at least one communication frame to be transmitted to the at least one other packet-switched apparatus.

11. The packet-switched apparatus of claim 10, wherein the apparatus is a first radio apparatus and the at least one other packet-switched apparatus is at least one of a second radio apparatus and a dispatch apparatus.

12. The packet-switched apparatus of claim 10, wherein the apparatus is a first dispatch apparatus and the at least one other packet-switched apparatus is at least one of a radio apparatus and a second dispatch apparatus.

13. A packet-switched system comprising a plurality of operatively coupled packet-switched apparatus, each of the apparatus comprising:

a processing device for executing process steps; and

a storage device coupled to the processing device for storing a set process steps executable by the processing device, the process steps comprising;

establishing a connection with at least one other packet-switched apparatus;

generating at least one communication frame comprising a payload field for carrying a payload and a signal field for carrying a control signal; and

causing the at least one communication frame to be transmitted to the at least one other packet-switched apparatus.

14. The packet-switched system of claim 13 further comprising a session layer server operatively coupled to the plurality of packet-switched apparatus and used for establishing the connection.

15. The packet-switched system of claim 14, wherein the session layer server is a Session Initiation Protocol server.

16. The packet-switched system of claim 13 further comprising an Operation and Maintenance server operatively coupled to the plurality of packet-switched apparatus.

17. The packet-switched system of claim 13, wherein a first packet-switched apparatus in at least a portion of the plurality of packet-switched apparatus has established a connection with the remaining packet-switched apparatus in the portion, the first packet-switched apparatus being configured for managing communications between all of the packet-switched apparatus in the portion.

18. The method of claim 17, wherein the first packet-switched apparatus is one of a dispatch apparatus and a radio apparatus.

19. The method of claim 17, wherein all of the packet-switched apparatus in the portion are one of dispatch apparatus and radio apparatus.

20. The packet-switched system of claim 13, wherein each packet-switched apparatus in at least a portion of the plurality of packet-switched apparatus has established a connection with the remaining packet-switched apparatus in the portion, each packet-switched apparatus in the portion being configured for managing communications between all of the packet-switched apparatus in the portion.
