ETSI ETSI TS 122 032 V15.0.0 (2018-06)53GPP TS 22.032 version 15.0.0 Release 151 Scope This Technical Specification specifies the stage 1 description of the Immedia
22、te Service Termination (IST) service which provides the means for the HPLMN to terminate all the activities of an HPLMN subscriber in a VPLMN. The purpose of this network feature is to enable the HPLMN to control the activities of its subscribers, particularly while they are roaming. If the HPLMN de
23、cides (based upon information received via Fraud Information Gathering System (FIGS) or other systems) that a roaming subscriber is behaving in a fraudulent or suspicious manner, the HPLMN can terminate all activities of the subscriber, including calls (including transferred and diverted calls) that
24、 are in progress. This procedure can also be used to terminate all the activities of a subscriber when the subscription has ended. The primary aim is to enable service providers/network operators to use IST to reduce the amount of money that they lose because of roaming fraud. 2 Normative references

In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TR 21.905: “3rd
27、 Generation Partnership Project; Technical Specification Group Services and System Aspects; Vocabulary for 3GPP Specifications“. 3 Definitions and abbreviations 3.1 Definitions For the purposes of this specification the following definitions apply: subscriber activities: subscriber activities that m
28、ust be terminated. 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.g. Call Hold, Call Waiting, Call Transfer, Call Forwarding, Unstructured Supplementary Service Data (USSD). 3.2 Abbreviations For
29、the purposes of the present document, the abbreviations given in TR 21.905 1 and the following abbreviations apply: IST Immediate Service Termination FIGS Fraud Information Gathering System 4 Immediate Service Termination (IST) 4.1 Description It shall be possible for the Home Public Land Mobile Net
30、work (HPLMN) to instruct any PLMN to terminate immediately all the activities of a specified HPLMN subscriber. ETSI ETSI TS 122 032 V15.0.0 (2018-06)63GPP TS 22.032 version 15.0.0 Release 15Immediate Service Termination (IST) is controlled by the HPLMN and can be triggered by the HPLMN only. A subsc
31、riber shall be specified by the International Mobile Subscriber Identity (IMSI). For subscribers that are marked as subscribed to a CAMEL-based service, IST shall be possible using Customised Application for Mobile network Enhanced Logic (CAMEL). IST shall also be possible for subscribers who are no
32、t marked as subscribed to any CAMEL-based service (see Annex A). 4.2 Applicability This network feature applies to all subscribed Bearer Services and Teleservices of the subscriber, except for emergency calls. 4.3 Normal procedure The HPLMN will normally direct a request for IST for a particular sub
33、scriber to the current Visited PLMN (VPLMN) of that subscriber and the PLMN visited by the subscriber immediately prior to visiting the current VPLMN NOTE: In practice, the IST command will be sent to individual Mobile-services Switching Centres (MSCs), and not to “VPLMNs“ as a whole (but such detai
34、l is for Stage 2 and not Stage 1). IST will therefore be sent to all MSCs in which the subscriber has (or may have) an active call, as logged by the HPLMN. These MSCs may be confined to the current VPLMN or may include MSC(s) in the PLMN visited by the subscriber immediately prior to visiting the cu
35、rrent VPLMN (or PLMNs visited even earlier). The VPLMN shall confirm receipt of the IST command. The VPLMN shall then terminate all activities of that subscriber in the VPLMN including ongoing calls and forwarded, deflected and transferred calls. The call records of calls terminated by the operation
36、 of IST shall contain a field indicating that the call terminated because of the operation of IST. The VPLMN shall then confirm to the HPLMN that all subscriber activities in that VPLMN have been terminated. If the specified subscriber has no activities in the VPLMN then the VPLMN shall inform the H
37、PLMN of this. 4.4 Exception procedures If after sending an IST command to a VPLMN, the HPLMN does not receive a positive acknowledgement from the VPLMN indicating receipt and comprehension of the IST command, the HPLMN should assume that the VPLMN does not support IST. 5 Security requirements betwee
38、n HPLMN and VPLMN It is expected that there will be a need for authentication and confidentiality of the communication made between PLMNs. These issues are for study under other work items within the SMG10 work programme. ETSI ETSI TS 122 032 V15.0.0 (2018-06)73GPP TS 22.032 version 15.0.0 Release 1
39、5Annex A (Informative): Normal procedure IST has been defined to work in co-ordination with existing GSM facilities. 1) The HPLMN changes the subscribers entry in the HLR to prevent the resumption of activity in the HPLMN and VPLMN after IST has terminated all subscriber activity. 2) The HPLMN sends
40、 a MAP “Cancel Location“ command to the VLR to prevent the resumption of activity by the subscriber within the VPLMN without reference to the HPLMN. 3) The HPLMN sends an IST command to the VPLMN, (possibly a specific MAP message). 4) The VPLMN confirms receipt and comprehension of the command. 5) T
41、he VPLMN terminates all activities of the subscriber indicated by the command. 6) The VPLMN confirms to the HPLMN that all subscriber activities have been terminated.
