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) and parameters contained in MAP services sent over the MSC-VLR interface (3GPP TS 29.002) 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) and parameters contained in MAP services sent over the MSC-VLR interface (3GPP TS 29.002) 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) and RANAP ((3GPP TS 25.413) 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) and parameters contained in MAP services sent over the SGSN-HLR interface (3GPP TS 29.00 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) and parameters contained in S1AP messages sent on the MME-eNodeB interface (3GPP TS 36.413). Interworking for supplementary services is given in 3GPP TS 29.011. Interworking for the short message service is given in 3GPP TS 23.040 and 3GPP TS 24.011. Interworking between the call control signalling of 3GPP TS 24.008 and the PSTN/ISDN is given in GSM 09.03@ 3GPP TS 29.007 and 3GPP TS 49.008. Interworking between the 'A' and 'E' interfaces for inter-MSC handover signalling is given in 3GPP TS 29.007 and 3GPP TS 49.008.
