ETSI ETSI TS 122 031 V13.0.0 (2016-02)53GPP TS 22.031 version 13.0.0 Release 131 Scope This Technical Specification specifies the stage 1 description of the Fraud Information Gathering System (FIGS) feature which provides the means for the HPLMN to monitor the activities of its
22、subscribers in a VPLMN. The purpose of this network feature is to enable the HPLMN to monitor the activities of its subscribers while they are roaming. The VPLMN collects information about a defined set of activities on monitored subscribers and sends this information back to the HPLMN. This enables
23、 the HPLMN to clear certain types of calls and so stop fraudulent use of the GSM system. This specification enables service providers/ network operators to use FIGS, and service limitation controls such as Operator Determined Barring (ODB) and Immediate Service Termination (IST), to limit their fina
24、ncial exposure to subscribers producing large unpaid bills. HPLMNs may also choose to monitor the activities of its subscribers within the HPLMN. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of the present document. Re

For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GS

B subscriber: The mobile subscriber originally called by the A subscriber. C subscriber: Th

The C subscriber may be fixed or mobile. call: both connection-oriented and connectionless services/events. call information: information about a call. call reference: a reference number for a call that shall remain constan

These can be call related events (e.g. call-set-up, call termination) or the invocation of call related and call independent supplementary services (e.
31、g. Call Hold, Call Waiting, Call Transfer, Call Forwarding, Unstructured Supplementary Service Data). 3.2 Abbreviations Abbreviations used in this specification are also listed in GSM 01.04. For the purposes of this specification the following abbreviations apply: FIGS Fraud Information Gathering Sy

33、ut a subscriber from the time the subscriber registers in that VPLMN to the time the last of the monitored activities is finished in that VPLMN, which can be after the subscriber“s de-registration from the VPLMN. The information received by the HPLMN shall be passed to the relevant network or servic
34、e providers and used to instruct the VPLMN to act in an appropriate way. Fraud information gathering is controlled by the HPLMN and can be activated and deactivated by the HPLMN only. The information is received in the HPLMN and is forwarded to fraud detection and control systems. Such systems are o
35、ut of the scope of this standard. The subscriber is specified by the IMSI or MSISDN. 4.2 Applicability This network feature applies to all subscribed Bearer Services and Teleservices and supplementary services of the subscriber. It is not possible to apply FIGS independently to individual Services.
36、The HPLMN shall be able to specify whether it would like call information on MO calls, MT calls, or both. 4.3 Normal Procedure The HPLMN shall be able to request a VPLMN to monitor a subscriber. See Annex A for the definition of the information to be sent for each call event. If the VPLMN cannot mon
37、itor the subscriber, it shall indicate this as a response to the FIGS request. The FDS will process this information and may then limit the activities of the subscriber using ODB or terminate the subscriber activities using IST, or may allow the subscriber to proceed. When the home network no longer
38、 wishes the subscriber to be monitored by the VPLMN it requests the VPLMN to stop monitoring the activities of the subscriber. Figure B.1 shows the sequence of FIGS messages passed during a normal case. ETSI ETSI TS 122 031 V13.0.0 (2016-02)73GPP TS 22.031 version 13.0.0 Release 135 Service conditio
39、ns 5.1 Control of monitoring of subscriber activities The HPLMN can request a VPLMN to begin monitoring the activities of a subscriber when the subscriber has registers on that VPLMN or at any time after registration. If the VPLMN is able to monitor a subscriber as requested it shall send a confirma
40、tion of monitoring message to the HPLMN. The HPLMN does not need to know the status of the target subscriber before initiation or subsequent termination of fraud information gathering. Fraud information cannot be switched on or off by the subscriber or other (unauthorised) party. Subscribers upon wh
41、ich fraud information gathering has been set shall not be able by interrogating the network to determine that they are subject to fraud information gathering. Subscribers upon which fraud information gathering has been set shall not be able, for example by significant changes to normal call set up t
42、imes, speech quality or general transmission characteristics, to determine that they are subject to fraud information gathering. If the VPLMN receives a request to monitor the activities of a subscriber and an activity to be monitored is already ongoing it is not necessary for the VPLMN to send info
43、rmation on this particular activity to the HPLMN. If the VPLMN receives a request to cease monitoring the activities of a subscriber and an activity is already ongoing and being monitored, the VPLMN shall immediately cease sending information on this activity to the HPLMN. 5.2 Number of calls monito
44、red by a VPLMN If the VPLMN has to monitor the activities of a large number of subscribers for FIGS this may degrade the performance of the VPLMN. Each VPLMN (in reality, each network entity involved in FIGS monitoring) will therefore have a maximum number of subscribers that it can monitor. If the
45、number of monitored subscribers has reached this upper limit the VPLMN shall reject requests for monitoring of subscribers from HPLMNs until the number of monitored subscribers decreases below the limit. Each VPLMN may have a limit per HPLMN on the number of subscribers from that HPLMN that it will
46、monitor. When an HPLMN has requested a VPLMN to monitor a number of subscribers equal to the limit for that HPLMN, the VPLMN can refuse any subsequent requests for FIGS monitoring from that PLMN, until the number of monitored subscribers drops below the limit. The principles behind the setting of th
47、ese limits are outside the scope of this specification. In order to minimise the number of subscribers that a VPLMN has to monitor, the HPLMN should ideally limit itself to requesting information about subscribers monitored activities in: - the current VPLMN; - the last previously served VPLMN. 5.3
48、Interworking with non-supporting networks If the HPLMN does not receive a positive acknowledgement to the request for FIGS monitoring sent to a VPLMN, it shall assume that the VPLMN does not support FIGS. The HPLMN may then act as appropriate (e.g. put appropriate ODB categories in place). ETSI ETSI
49、 TS 122 031 V13.0.0 (2016-02)83GPP TS 22.031 version 13.0.0 Release 135.4 Information Delivery Time The need for up to date information is a critical part of any fraud information system. The sooner data is transferred to the HPLMN, the sooner fraud can be stopped. Therefore the prescribed information shall be transferred from the VPLMN network to the HPLMN within two minutes of the occurrence of a FIGS-monitored event, if real time implementations of FIGS are used. The information should be transferred from the VPLMN to the HPLMN over appropriate communication lin
