Patent ID: 7586907

Claim:
One or more circuits for use in a handheld wireless communication device, the one or more circuits comprising: at least one processor operably coupled to at least one memory and to radio frequency circuitry for communicating voice signals over a radio frequency network, the at least one processor operable to, at least, store first voice data representative of a first voice signal in a queue in the at least one memory, convert the first voice data from the queue to a first analog representation of the first voice signal, convert to second voice data a second analog representation of a second voice signal, depacketize received voice packets into the first voice data and packetize the second voice data into transmit voice packets, adjust operation of the queue based upon a propagation delay of a communication network; and wherein adjusting operation of the queue comprises adjusting queuing time according to a measurement of propagation delay of the communication network, when variation of propagation delay rises above a certain level.
