Maintaining audio communication in a congested communication channel
First Claim
1. A method of maintaining audio communication in a communication channel for transmission of speech in the audio communication between a sender side and a receiver side, the communication channel comprising at least a first channel and a second channel, the first channel being utilizable for transmission of speech, the method comprising:
- monitoring a quality of service of the first channel;
upon determining that the quality of service of the first channel is below a pre-selected threshold;
interrupting the sending of speech data of the speech from the sender side over the first channel while retaining the second channel of the communication channel, andindicating that the first channel is inactive and that the retained second channel is to be used for continuing the audio communication via the retained second channel;
converting speech to text at the sender side for transmitting the text to the receiver side via the retained second channel; and
transmitting the text over the retained second channel of the communication channel for conversion of the text to speech at the receiver side.

Abstract
The invention relates to a communication system and a method of maintaining audio communication in a congested communication channel currently bearing the transmission of speech in audio communication between a sender side and a receiver side, the communication channel having at least one signaling channel and at least one payload channel having a quality of service. During the audio communication the quality of service of the payload channel is monitored. If the quality of service of the payload channel is below a threshold the speech at the respective sender side is converted to text; and transmitted over the retained communication channel to the respective receiver side. The text may be converted back to speech at the receiver side.

13. A non-transitory computer readable medium having an application stored thereon, the application defining instructions executable by a processor of a communication device for carrying out a method when the application is run by the processor, the method comprising:
-
monitoring a quality of service of a first channel of a communication channel between a sender side and a receiver side; upon determining that the quality of service of the first channel is below a pre-selected threshold; interrupting the sending of speech data of the speech from the sender side over the first channel while retaining a second channel of the communication channel, and indicating that the first channel is inactive and that the retained second channel is to be used for continuing the audio communication via the retained second channel; converting speech to text for transmitting the text to the receiver side via the retained second channel; and transmitting the text over the retained second channel of the communication channel for conversion of the text to speech at the receiver side. - View Dependent Claims (14, 15)

16. A communication apparatus, comprising:
-
a processor configured to control communication between a first communication device and a second communication device, the processor configured to carry out a method comprising; monitoring a quality of service of a first channel of a communication connection between the first and second communication devices; upon determining that the quality of service of the first channel is below a pre-selected threshold; interrupting the sending of speech data of the speech from the first communication device over the first channel while retaining a second channel of the communication channel, and indicating that the first channel is inactive and that the retained second channel is to be used for continuing the audio communication via the retained second channel; converting speech to text at the first communication device for transmitting the text to the second communication device via the retained second channel; and transmitting the text over the retained second channel of the communication channel for conversion of the text to speech at the second communication device. - View Dependent Claims (17, 18, 19, 20)
