Patent ID: 7450601

Claim:
A method for controlling a jitter buffer in a first node of a communication system, wherein the jitter buffer is adapted to buffer a stream of blocks of compressed speech information generated in a second node in the communication system, transmitted to and received in the first node, the method comprising the steps of: selecting blocks in said stream of blocks of compressed speech information according to a predetermined rule based on the current buffering delay of the jitter buffer and at least one characteristic of said blocks of compressed speech information; applying predetermined actions to the selected blocks aiming at reducing buffering delay in the jitter buffer; wherein said predetermined rule for selecting blocks includes selecting blocks representing speech segments having energy levels below a first energy level threshold if the current delay of the jitter buffer exceeds a first delay threshold value; wherein said predetermined rule for selecting blocks includes selecting blocks representing speech segments having energy levels below a second energy level threshold, which is higher than the first energy level threshold, if the current delay of the jitter buffer exceeds a second delay threshold value greater than the first delay threshold value.
