ETSI 3GPP TS 29.010 version 5.2.0 Release 5 7 ETSI TS 129 010 V5.2.0 (2002-12) 1 Scope 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 (25.413) iv) to provide a detailed specification for the interworking as in i) and ii) above when the MSC also processes the information. 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. 1.1 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.

Throughout this specification the term GSM refers to GERAN A/Gb mode. Iu mode: mode of operation of the MS when connected to the Core Network via GERAN or UTRAN and the Iu interface. Throughout this specification the term UMTS refers to UTRAN or GERAN Iu mode. 2 Classification of interworking cases 2.1 Transparent procedures The following MSC procedures require transparent mapping of access protocol information elements into MAP parameters and vice versa (see 3GPP TS 29.002 for definitions and the use of the procedures): - location update; - forward new TMSI; - provide IMSI; - obtain IMEI; - check IMEI; - authenticate; - trace subscriber activity. ETSI 3GPP TS 29.010 version 5.2.0 Release 5 9 ETSI TS 129 010 V5.2.0 (2002-12) 2.2 Non-transparent procedures Procedures in this class require processing in the MSC and information element mapping. These procedures include those related to: - outgoing call set-up; - incoming call set-up; - handover; - cipher mode setting; - location services. 3 Interworking in the MSC, Transparent case 3.1 General When the MSC receives a forward message from the BSS (possibly forwarded transparently from the MS), it will invoke the desired MAP service and establish a cross reference between the BSSAP procedure and the MAP procedure in order to return the result of the operation to the BSS (which may forward it transparently to the MS. The cross reference is deleted when the MSC terminates the MAP procedure. Positive or negative results of the MAP procedure are returned in the appropriate BSSAP message. The parameters of the forward BSSAP message are mapped by a one-to-one mapping into the parameters of the MAP service. However, in some cases parameters received on the radio path may be suppressed at the MSC because they are related to another protocol entity, e.g. information related to RR-management may be included in MM-management messages. Similarly, parameters received in the (positive) MAP service response are mapped one-to-one into parameters of the corresponding backward BSSAP message. A negative outcome, as carried in various MAP services (MAP specific service response, MAP_U_ABORT, MAP_P_ABORT, MAP_NOTICE and premature MAP_CLOSE, see 3GPP TS 29.002 for definitions) is mapped into a cause value in the required backward BSSAP message. In this case several negative results of MAP may be mapped into the same BSSAP cause value, i.e. without discrimination between these negative results. NOTE: For O & M purposes, the MAP procedure entity in the MSC may require a more detailed overview of negative results than the MS. ETSI
