摘要： A system and method control a setup of a connection in a communication network including a set of nodes, such as Mobile Switching Centers (MSCs) and Media Gateways (MGWs). In one example, a speech connection is established between MGWs subject to the control of the MSCs, which can selectively activate or deactivate codecs along the connection. The codecs potentially affect connection quality by differing amounts. A Total Accumulated Impairment (TAI) element is forwarded between the MSCs and updated by the MSCs that include individual partially accumulated impairment values corresponding to the supported codec candidates. Each individual indicator value provides information representative of the expected accumulated impairment along a candidate connection path leading up to, and including, the corresponding codec. By providing information pertaining to the expected accumulated impairment along each candidate connection path, the MSCs can determine an optimum sequence of codecs to minimize the overall connection impairment.

摘要： The invention relates to the setting up of a connection between an originating terminal and a terminating terminal. Both terminals may connect via the same access network. The access network accesses a core network through an access gateway. The access gateway transmits and/or receives connection set-up signalling transmitted along a signalling path through at least the core network. Using an information element in the connection set-up signalling, information on media plane access needs of nodes in the signalling path is collected and provided for determining whether a local shortcut of a media path can be established in the access network.

摘要： A method and a device for initiating the bypassing of a pair of transcoding operations that are performed in series by a first transcoder arranged together with a first communication terminal on a local side of a communication network and by a second transcoder arranged together with a second communication terminal on a distant side of the communication network are described. The method includes receiving from the distant side information about an encoding format currently in use on the distant side and about encoding capabilities of the distant side and transmitting to the distant side information about an encoding format currently in use on the local side and about encoding capabilities of the local side to enable on one or on both sides a change of the encoding format currently in use prior to initiating the bypassing of the transcoding operations.

The detected tone signal is coded into bits of a TFO or TRAU-like frame for sending through the GCME link, including setting bits to mark the frame as a containing tone signalling information and setting bits to identify the detected tone signal, whereby the tone signalling information is transported in-band through the GCME link as a marked TFO or TRAU-like frame. At the remote exit from the GCME link, the marked frame is detected and the tone signal regenerated in dependence upon the bits of the marked frame.
