ETSI ETSI TS 148 060 V13.0.0 (2016-01)63GPP TS 48.060 version 13.0.0 Release 131 Scope When 64 kbit/s traffic channels are used on the Abis interface, the speech shall be coded according to CCITT Recommendation G.711 and the data rate adaptation shall be as specified in 3GPP T

19、S 44.021 and 3GPP TS 48.020. In the case where 16 kbit/s traffic channels are used for full rate speech, enhanced full rate speech, Adaptive Multi-Rate speech, Adaptive Multi-Rate Wideband speech or full rate data service, then the present document shall apply for frame structure and for control of

20、remote transcoders and additional rate adaptors. For Adaptive Multi-Rate speech the present document specifies the 16 kBit/s submultiplexing, both for the full and the half rate traffic channels (TCH/AFS, TCH/AHS, TCH/WFS and O-TCH/WHS). The specification for 8 kBit/s submultiplexing is given in 3GP

21、P TS 48.061, both for the full and the half rate traffic channels (TCH/AFS and TCH/AHS). Additionally, the present document specifies the 32 kBit/s submultiplexing for Adaptive Multi-Rate Wideband speech. However it reuses the frame structure of the 16 kBit/s submultiplexing for Adaptive Multi-Rate

22、speech. The use and general aspects of the Abis interface are given in 3GPP TS 48.051. NOTE: The present document should be considered together with the 3GPP TS 06 series of specifications, 3GPP TS 44.021 (Rate Adaptation on the MS-BSS Interface) and 3GPP TS 48.020 (Rate Adaptation on the BS/MSC Int

39、anscoders/rate adaptors are positioned remote to the BTS, the information between the Channel Codec Unit (CCU) and the remote Transcoder/Rate Adaptor Unit (TRAU) is transferred in frames with a fixed length of 320 bits (20 ms). In the present document, these frames are denoted “TRAU frames“. Within

40、these frames, both the speech/data and the TRAU associated control signals are transferred. The Abis interface should be the same if the transcoder is positioned 1) at the MSC site of the BSS or if it is positioned 2) at the BSC site of the BSS. In case 1), the BSC should be considered as transparen

41、t for 16 kbit/s channels. In case of 4,8 and 9,6 kbit/s channel coding when data is adapted to the 320 bit frames, a conversion function is required in addition to the conversion/rate adaption specified in 3GPP TS 48.020. This function constitutes the RAA. In case of 14,5 kbit/s channel coding, no R

42、AA rate adaption is required because V.110 framing is not used. The TRAU is considered a part of the BSC, and the signalling between the BSC and the TRAU (e.g. detection of call release, handover and transfer of O - “Remote Speech Handler Function“ (RSHF); - The RAA function in case of 4.8 and 9.6 k
