Abstract

Methods and systems for indicating an audio forwarding failure at a Radio-over-Internet-Protocol (RoIP) gateway device of a RoIP system is disclosed. In one step, audio communication is detected from a radio handset communicatively coupled with the RoIP gateway device and is buffered. When an error in forwarding the audio communication to at least a portion of devices connected to the RoIP system, an audio notification indicative of the error is sent to the radio handset after determining the audio communication from the radio handset has ended.

Claims (37)

1. A method of indicating an audio forwarding failure at a Radio-over-Internet-Protocol (RoIP) gateway device of a RoIP system, the method comprising:

detecting audio communication from a radio handset communicatively coupled with the RoIP gateway device;

responsive to the detecting, buffering at least a portion of the audio communication wherein the buffering has a time limit; determining an error in forwarding the audio communication to at least a portion of devices connected to the RoIP system where audio forwarding conditions are not met, wherein the error determination continues up to the time limit of the buffering; and

sending an audio notification indicative of the error to the radio handset after determining the audio communication from the radio handset has ended, wherein:

the audio notification corresponds to a carrier operated relay (COR) signal,

the audio notification is transmitted when a valid audio communication is detected from the radio handset, and

a type of the audio notification is further indicative of an error type of the error in forwarding the audio communication.

2. The method of claim 1 , wherein the radio handset comprises a half-duplex radio handset.

3. The method of claim 1 , wherein the audio notification comprises a recorded message or audio tone.

4. The method of claim 1 , further determining the audio forwarding conditions are not met prior to a threshold amount of buffering has occurred.

5. The method of claim 1 , wherein determining the error comprises determining, after forwarding the audio, that the audio has failed to be successfully forwarded to at least one receiving device of the RoIP system.

6. The method of claim 1 , wherein a size or the time limit for the buffering is determined based on user input.

7. A RoIP system for indicating an audio forwarding failure at a Radio-over-Internet-Protocol (RoIP) gateway device, the RoIP system comprising:

a radio handset;

the RoIP gateway device, wherein the RoIP gateway device:

detects audio communication from the radio handset communicatively coupled with the RoIP gateway device,

buffers at least a portion of the audio communication upon the detection of audio communication, wherein the buffering has a time limit;

determines an error in forwarding the audio communication to at least a portion of devices connected to the RoIP system where audio forwarding conditions are not met, wherein the error determination continues up to the time limit of the buffering; and

sends an audio notification indicative of the error to the radio handset after determining the audio communication from the radio handset has ended, wherein:

the audio notification corresponds to a carrier operated relay (COR) signal,

the audio notification is transmitted when a valid audio communication is detected from the radio handset, and

a type of the audio notification is further indicative of an error type of the error in forwarding the audio communication.

8. The RoIP system for indicating the audio forwarding failure at the RoIP gateway device of claim 7 , wherein the radio handset comprises a half-duplex radio handset.

9. The RoIP system for indicating the audio forwarding failure at the RoIP gateway device of claim 7 , wherein the audio notification comprises a recorded message, Morse code, or audio tone.

10. The RoIP system for indicating the audio forwarding failure at the RoIP gateway device of claim 7 , wherein a size or the time limit for the buffering is determined based on user input.

11. A RoIP system for indicating an audio forwarding failure at a Radio-over-Internet-Protocol (RoIP) gateway device, the RoIP system comprising one or more processors and one or more memories with code for:

detecting audio communication from a radio handset communicatively coupled with the RoIP gateway device;

responsive to the detecting, buffering at least a portion of the audio communication wherein the buffering has a time limit;

determining an error in forwarding the audio communication to at least a portion of devices connected to the RoIP system where audio forwarding conditions are not met, wherein the error determination continues up to the time limit of the buffering; and

sending an audio notification indicative of the error to the radio handset after determining the audio communication from the radio handset has ended, wherein:

the audio notification corresponds to a carrier operated relay (COR) signal,

the audio notification is transmitted when a valid audio communication is detected from the radio handset, and

a type of the audio notification is further indicative of an error type of the error in forwarding the audio communication.

12. The RoIP system for indicating the audio forwarding failure at the RoIP gateway device of claim 11 , wherein the radio handset comprises a half-duplex radio handset.

13. The RoIP system for indicating the audio forwarding failure at the RoIP gateway device of claim 11 , wherein the audio notification comprises a recorded message or audio tone.

14. The RoIP system for indicating the audio forwarding failure at the RoIP gateway device of claim 11 , further determining the audio forwarding conditions are not met prior to a threshold amount of buffering has occurred.

15. The RoIP system for indicating the audio forwarding failure at the RoIP gateway device of claim 11 , wherein determining the error comprises determining, after forwarding the audio communication, that the audio communication has failed to be successfully forwarded to at least one receiving device of the RoIP system.
