TECHNIQUE FOR CONTROLLING CODEC SELECTION ALONG A COMPLEX CALL PATH |
摘要 |
<p>The invention relates to a technique of operating a call control node (MSC1, TSC2 - TSC4, MSC5) controlling at least one section of a call path. The call path includes between two opposite edge nodes (MSC1, MSC5) a multi-section harmonization path along which codec selection is to be harmonized. A method embodiment of the technique, wherein the call control node is a transfer node (TSC2 - TSC4) in the harmonization path between the edge nodes, comprises the steps of determining if the call control node is a transfer node of the harmonization path; determining if a codec used for the at least one section controlled by the call control node fulfils a predefined harmonization criterion; and providing, in case the used codec does not fulfil the harmonization criterion, a harmonization trigger indication to at least one of the edge nodes of the harmonization path for initiating harmonization.</p> |
