TS 06.92 (SA4)
Comfort noise aspects for Adaptive Multi-Rate speech traffic channels

ToC   3GPP‑Page   ETSI‑search   Help    
(P) GSM Rel-98 v7.1.1  1999/12  13 p.


Rapporteur:  BRUHN, Stefan
Descendant:  TS 26.092

This TS gives the detailed requirements for the correct operation of the background acoustic noise evaluation, noise parameter encoding/decoding and comfort noise generation in Mobile Stations (MSs) and Base Station Systems (BSSs) during Discontinuous Transmission (DTX) on adaptive multi-rate full rate and half rate speech traffic channels.

The requirements described in this TS are mandatory for implementation in all GSM MSs capable of supporting the adaptive multi-rate full rate and half tate speech traffic channels.

The receiver requirements are mandatory for implementation in all GSM BSSs capable of supporting the adaptive multi rate full rate and half rate speech traffic channels, the transmitter requirements only for those where downlink DTX will be used.

In case of discrepancy between the requirements described in this TS and the fixed point computational description of these requirements contained in TS 06.73, the description in TS 06.73 will prevail.
