ETSI TS 122 032 specifies the stage 1 description of the Immediate 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 decides (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 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.
