19、ion Gathering System (FIGS) feature which provides the means for the HPLMN to monitor the activities of its subscribers in a VPLMN. Three levels of FIGS service are defiied, levels 1 to 3. Level 1 will use the facilities provided by Transferred Account Procedure (TAP). Levels 2 and 3 will use facili
20、ties provided by Customised Applications for Mobile network Enhanced Logic (CAMEL), in particular, the information flows between the GSM Service Switching Function (gsmSSF) and GSM Service Control Function (gsmSCF). Phase 1 and Phase 2 CAMEL facilities will be used. Connection-orientated services on

B subscriber: The mobile sub
26、scriber originally called by the A subscriber. C subscriber: The subscriber to whom the B subscriber has requested that calls be forwarded. The C subscriber may be fixed or mobile. call: connection-oriented service/event. ETSI 3GPP TS 43.031 version 5.0.0 Release 5 6 ETSI TS 143 031 V5.0.0 (2002-06)
27、 GSM Service Control Function (gsmSCF): A functional entity that contains the CAMEL service logic to implement OSS. It interfaces with the gsmSSF and the HLR. GSM Service Switching Function (gsmSSF): A functional entity that interfaces the MSC/GMSC to the gsmSCF. The concept of the gsmSSF is derived
28、 from the IN gsmSSF, but uses different triggering mechanisms because of the nature of the mobile network. Originating CAMEL Subscription Information (O-CSI): The O-CSI identifies the subscriber as having originating CAMEL services. Supplementary Service Notification CAMEL Subscription Information (
29、SS-CSI): The SS-CSI identifies the subscriber as having supplementary service invocation notification CAMEL services. Terminating CAMEL Subscription Information (T-CSI): The T-CSI identifies the subscriber as having terminating CAMEL services. VMSC: The serving MSC in the VPLMN. 3.2 Abbreviations Ab

32、There are three levels of monitoring of subscriber activities using FIGS. Level 1 an accelerated TAP procedure associated with a mechanism such as Hot Billing is implemented in the MSC of the VPLMN. Level 2 Level 3 CAMEL is used to gather information, but only at the beginning and the end of the cal
33、l. CAMEL provides full information on subscriber activities, as defined in 3GPP TS 42.031, i.e. call start and end times, and partial call records. Notification of the invocation of Explicit Call Transfer, Call Deflection, Call Forwarding, Call Hold and Multi Party Service is also given. ETSI 3GPP T
34、S 43.031 version 5.0.0 Release 5 7 ETSI TS 143 031 V5.0.0 (2002-06) 5 FIGS Level 1: Accelerated TAP Records 5.1 Method of FIGS Setting A PLMN shall request that a VPLMN monitor a designated subscriber using FIGS level 1 by setting a Hot Billing flag in the subscriber data stored in the HLR of the HP
35、LMN. This data is drawn down by the VPLMN when the subscriber first registers in the VPLMN. If the HPLMN wishes to begin monitoring of a subscriber using FIGS Level 1 when the subscriber is already registered in the VPLMN, it resets the subscriber data in the VPLMN using command Insert Subscriber Da
36、ta. 5.2 Information Flows If a subscriber in a VPLMN is set in the subscriber categories to be monitored using FIGS Level 1 the VMSC shall process and return the TAP records for that subscriber in accordance with the guidelines given in current and future version of TAP. 6 FIGS and CAMEL Architectur
37、e for FIGS Levels 2 and 3 FIGS provides the following information flows to the HPLMN, with respect to roaming subscribers monitored by FIGS Levels 2 and 3. FIGS Level 2: call start and end times (both MO, MT and forwarded calls). (At CAMEL Phase 1 the gsmSSF will not put a timestamp on messages. The
38、 arrival times of messages at the gsinSCF will be used for call start and end times.) FIGS Level 3: As for level 2 with the addition of partial call information (accumulated duration of call still in progress) (CAMEL Phase only); notification of the invocation of ECT, CD and MPTY, CF and call hold (
39、CAMEL Phase 2 only). Further phases of CAMEL will provide the functionality to check the IMEI of the ME used by a CAMEL subscriber. Other information required by 3GPP TS 42.03 1, annex A, that is not provided by CAMEL Phase 1 and CAMEL Phase 2, may also be provided by further phases of CAMEL. The ar
40、chitecture of the services provided by FIGS Levels 2 and 3 is given in the diagrams below. Thick lines indicate possible CAMEL monitoring/control relationships.

42、al Call Forward or the HLR has determined, before the call is extended to VPLMN B, that the B subscriber is not reachable. In all other cases the call must be extended to the VMSC. The information flows required by FIGS levels 2 and 3 can be provided by the information flows on the CAP interfaces be
43、tween the gsmSCF and the gsmSSF in the interrogating and visiting networks. The interface between the gsmSCF and the Fraud Detection System (FDS) is non-standard. 7 7.1 FIGS Levels 2 and 3 Method of FIGS Setting A PLMN shall request that a VPLMN monitor a designated subscriber using FIGS levels 2 or
44、 3 by setting the O-CSI, T- CSI and SS-CSI (level 3 only) flags in the subscriber data stored in the HLR of the HPLMN. This data is drawn down by the VPLMN when the subscriber first registers in the VPLMN. If the HPLMN wishes to begin monitoring of a subscriber using FIGS Level 2 or 3 when the subsc
45、riber is already registered in the VPLMN, it resets the subscriber data in the VPLMN using command Insert Subscriber Data. 7.2 Information Flows FIGS Levels 2 and 3 will be treated together in this section but it should be remembered that partial call records and SS notification invocation is not av
46、ailable with FIGS Level 2. Each item of call data required by FIGS will be considered in turn and the information flows within CAMEL which provide this data given. Text applies to the implementation of FIGS functionality using both Phases 1 and 2, unless otherwise stated. MO and MT calls will be tre
47、ated together. If a message or DP is named as O/T-Answer, for instance, this means that if the call is MO, the relevant DP is O-answer, and that if the call is MT, the relevant DP is T-answer. Diagrams showing the information flows for FIGS levels 2 and 3 are given in Annex A. 7.2.1 Mobile Originate
48、d and Mobile Terminated Calls 7.2.1.1 Call Start Time Information regarding a call attempt can be obtained from the InitiaZDP message sent from the gsmSSF to the gsmSCF. This message is sent after a control relationship for the call has been set up between the gsmSSF and gsmSCF. This message will pr
49、ovide notification to the FDS that a FIGS monitored subscriber has made a call attempt, or that an attempt is being made to call a FIGS monitored subscriber. CAMEL Phase 1 The call, however, has not been connected at the time of the InitiaZDP message. The gsmSCF must therefore arm DP O/T-answer, so that the gsmSSF will inform the gsmSCF when the called party answers/connects. The gsmSCF arms the DP with message Request-Report-BCSM-Event sent to the gsmSSF. If the called party answers, the gsmSSF sends Event-Report-BCSM (Notify and Continue) to gsmSCF. This message provides n
