The present document specifies the mapping of the AMR generic frame format (3GPP TS 26.101) to the Iu Interface (3GPP TS 25.415 [7]), the Uu Interface and the Nb Interface (3GPP TS 29.415). It further specifies the mapping of Enhanced Full Rate (GSM_EFR) coded speech and of PCM 64 kBit/s (ITU-T G.711 [9]) coded speech to the Nb Interface in a BICC-based circuit switched core network.
The present document also specifies the mapping of Full Rate (GSM_FR) coded speech and of Half Rate (GSM_HR) coded speech to the Nb Interface in a BICC-based circuit switched core network.
The present document also specifies the transport of the AMR Codec Types, the AMR-WB Codec Types, the GSM_EFR Codec, the GSM_FR Codec, the GSM_HR Codec and the ITU-T G.711 Codec over the A-Interface over IP (3GPP TS 48.002 [11]) and the Nb-Interface in a SIP-I -based circuit switched core network (3GPP TS 23.231 [12]).
