The contents of the present document may be subject to continuing work within SMG and may change following formal SMG approval. Should SMG modi6 the contents of the present document it will the

ETSI GSM 02.32 version 8.0.1 Release 1999 5 ETSI TS 101 749 V8.0.1 (2001-06) 1 Scope The present document specifies the stage 1 description of the Immediate Service Termination (IST

15、) 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 decides (based upon informati

16、on 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 are in progress. This proc

17、edure can also be used to terminate all the activities of a subscriber when the subscription has ended. The primary aim is to enable service providershetwork operators to use IST to reduce the amount of money that they lose because of roaming fraud. 2 Re fe re nces The following documents contain pr

22、GSM 02.32 version 8.0.1 Release 1999 6 ETSI TS 101 749 V8.0.1 (2001-06) 4 Immediate Service Termination (IST) 4.1 Description It shall be possible for the Home Public Lands Mobile Network (HPLMN) to instruct any PLMN to terminate immediately all the activities of a specified HPLMN subscriber. Immedi

23、ate Service Termination (IST) is controlled by the HPLMN and can be triggered by the HPLMN only. A subscriber 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 Appl

24、ications for Mobile network Enhanced Logic (CAMEL). IST shall also be possible for subscribers who are not marked as subscribed to any CAMEL-based service (see annex A). 4.2 Appl ica bi I i ty This network feature applies to all subscribed Bearer Services and Teleservices of the subscriber, except f

25、or emergency calls. 4.3 Normal procedure The HPLMN will normally direct a request for IST for a particular subscriber 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

26、 be sent to individual Mobile-services Switching Centres (MSCs), and not to “VPLMNs“ as a whole (but such detail 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

27、 current VPLMN or may include MSC(s) in the PLMN visited by the subscriber immediately prior to visiting the current 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 ongo

28、ing calls and forwarded, deflected and transferred calls. The call records of calls terminated by the operation 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 hav

29、e been terminated. If the specified subscriber has no activities in the VPLMN then the VPLMN shall inform the HPLMN 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

30、of the IST command, the HPLMN should assume that the VPLMN does not support IST. 5 Security requirements between 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

31、within the SMG10 work programme. ETSI GSM 02.32 version 8.0.1 Release 1999 7 ETSI TS 101 749 V8.0.1 (2001-06) Annex 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 resum

32、ption of activity in the HPLMN and VPLMN after IST has terminated all subscriber activity. 2) The HPLMN sends 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 V

33、PLMN, (possibly a specific MAP message). 4) The VPLMN confirms receipt and comprehension of the command. 5) The 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.
