Patent ID: 8254376

Claim:
A method at a network node comprising an adaptive jitter buffer of dynamically adjusting the buffer delay of said adaptive jitter buffer when receiving media stream packets of a media stream from a packet switched network, wherein said method comprises the following steps: inserting packets arriving to the network node into the jitter buffer, iteratively adapting the jitter buffer at an interval, Trep in , when said media stream is in a media or talk spurt, such that a jitter protection time, T jit , is being updated on the basis of the variation, N max −N min of the number of packets, N, pending in the jitter buffer, T jit being a current target value for the maximum buffering delay for said jitter buffer, each iteration being executed by: updating a smallest value, N min , and a largest value, N max , of N, N being monitored over an adaptation interval, ADAPT_INT, ADAPT_INT, defining a predetermined number of iterations, calculating a new target value, T j , on the basis of the variation of N, T j being an indicator of the required adaptation of T jit , such that: T j =( N max −N min )*Trep in and adjusting T jit with the value of T j in case the number of iterations since the last adjustment of T jit equals ADAPT_INT.
