ETSI TS 129 010 V15.1.0:2019-04

The scope of the present document is: i) to provide a detailed specification for the interworking between information elements contained in layer 3 messages sent on the MS-MSC interface (Call Control and Mobility Management parts of 3GPP TS 24.008 [4]) and parameters contained in MAP services sent over the MSC-VLR interface (3GPP TS 29.002 [9]) where the MSC acts as a transparent relay of information; ii) to provide a detailed specification for the interworking between information elements contained in BSSMAP messages sent on the BSC-MSC interface (3GPP TS 48.008 [12]) and parameters contained in MAP services sent over the MSC-VLR interface (3GPP TS 29.002 [9]) where the MSC acts as a transparent relay of information; iii) to provide a detailed specification for the interworking between information elements contained in BSSMAP messages (3GPP TS 48.008 [12]) and RANAP ((3GPP TS 25.413 [7]); iv) to provide a detailed specification for the interworking as in i) and ii) above when the MSC also processes the information; v) to provide a detailed specification for the interworking between information elements contained in layer 3 messages sent on the MS-SGSN interface (GPRS mobility part of 3GPP TS 24.008 [4]) and parameters contained in MAP services sent over the SGSN-HLR interface (3GPP TS 29.002 [9]); vi) to provide a detailed specification for the interworking between information elements contained in RANAP messages sent on the SGSN-RNC interface (3GPP TS 25.413 [7]) and parameters contained in S1AP messages sent on the MME-eNodeB interface (3GPP TS 36.413 [21]); vii) to provide a detailed specification for the interworking between information elements contained in BSSMAP messages (3GPP TS 48.008 [12]) or RANAP messages (3GPP TS 25.413 [7]) during SRVCC handovers.
