Method and system for maintenance of a Transcoder-Free-Operation-Mode for an end-to-end-connection in a mobile communication network

摘要

The method involves comparing information in a transmission protocol regarding the codec mode to be used in the connections in a switching device (MSC) for at least two connection parts of an end-to-end connection to a media gateway. If the information is different then signaling to Trans Break Equipment (TBE) is carried out. Matching codec mode information for the connection parts is determined by the Trans Break Equipment. An independent claim is also included for the following: (a) an arrangement for maintaining a transcoder-free operation mode for an end-to-end connection in a mobile communications network.
