Abstract
A method and apparatus for reducing voice latency in a voice-over-data wireless communication system. In a transmitter, audio information to be transmitted is first encoded using a voice encoder operating in a first mode of operation. At least one operating parameter in the transmitter is measured by a processor, the least one operating parameter proportional to a latency between the transmitter and receiver. If the at least one operational parameter exceeds a predetermined threshold, the voice encoder is instructed to operate in a second mode of operation. When the at least one operational parameter falls below a second predetermined threshold, the voice encoder is instructed to operate in the first mode of operation.
Claims18
A method for reducing voice latency in a voice-over-data wireless communication system, comprising the steps of:
- operating a voice encoder in a first mode of operation in a transmitter;
- measuring an operating parameter of said transmitter, said operating parameter proportional to a latency between said transmitter and a receiver;
- operating said voice encoder in a second mode of operation if said operating parameter exceeds a first predetermined threshold.
An apparatus for reducing voice latency in a voice-over-data wireless communication system, comprising:
- a voice encoder for encoding audio information into data frames at a transmitter;
- a processor for determining the value of an operating parameter within said transmitter, said operating parameter proportional to a latency between said transmitter and a receiver, said processor further for comparing said operating parameter to a predetermined threshold, said processor further for controlling said voice encoder to operate in a first mode of operation if said operating parameter is less than said predetermined threshold and for controlling said voice encoder to operate in a second mode of operation if said operating parameter is greater than said predetermined threshold.
