Abstract
Method and arrangement in a network node for adapting a property of source coding to the quality of a communication link in packet switched conversational services in a communication system. The method comprises obtaining (404) information related to the quality of a communication link. The method further comprises selecting (406) a source coding mode with an associated source coding delay, based on the obtained information and the associated source coding delay. The selected source coding mode is selected from a set of at least two source coding modes associated with different source coding delays, and is to be used when source coding voice data to be transmitted over the communication link.

A method in a network node, for adapting a property of source coding to the quality of a communication link in packet switched conversational services in a communication system, the method comprising:
- obtaining information related to the quality of said communication link,
- selecting a source coding mode with an associated source coding delay, based on the obtained information and the associated source coding delay,
- wherein the selected source coding mode is to be used when source coding voice data to be transmitted over the communication link, and
- wherein the source coding mode is selected from a set of source coding modes associated with different source coding delays.
An arrangement in a network node, adapted to adapt a property of source coding to the quality of a communication link in packet switched conversational services in a communication system, the arrangement comprising:
- a quality unit, adapted to obtain information related to the quality of a communication link,
- a selecting unit, adapted to select a source coding mode with an associated source coding delay, based on the obtained information and the associated source coding delay,
- wherein the selected source coding mode is to be used when source coding voice data to be transmitted over the communication link, and
- wherein the source coding mode is selected from a set of source coding modes associated with different source coding delays.
