适用范围

The present document gives a description of the general baseband operation of full rate speech traffic channels in the transmitter and in the receiver of GSM Mobile Stations (MS)s and Base Station Systems (BSS)s during Discontinuous Transmission (DTX). For clarity@ the description is structured according the block diagrams in figures 1 and 4. Except in the case described next@ this structure of distributing the various functions between system entities is not mandatory for implementation@ as long as the operation on the air interface and on the speech decoder output remains the same. In the case of BSSs where the speech transcoder is located remotely in the Base Station Controller (BSC)@ the implementation of the interfaces between the DTX Handlers and the Radio Subsystem (RSS) as described in the present document together with all their flags is mandatory@ being a part of the A-bis- interface as described in GSM 08.60. In this case the various flags also serve to avoid additional delays. The DTX functions described in the present document are mandatory for implementation in all GSM MSs. The receiver requirements are mandatory for implementation in all GSM BSSs@ the transmitter requirements only for those where downlink DTX will be used. DTX shall be in operation in GSM MSs if commanded so by the network@ see GSM 04.08.
