Cellular operators are investing heavily in the development of so-called AntiFraud systems. With their help it is possible to monitor the GSM termination using gateways. When the suspiciously high activity is detected, the systems block SIM-cards, which are used to terminate calls.
AntiFraud analytical and calling systems
Any AntiFraud system includes 2 components - the analytic and calling. The analytic component works by means of the following principle: analyzing the various parameters of the subscriber behavior in a network, it identifies terminated GSM traffic, whereupon the SIM-lock mechanism is activated. The antifraud calling system calls numbers, which fall under the suspicions, by VoIP. If the call takes place, it signals the cellular operator about GSM termination.
There are special "humanity parameters" to determine terminated SIM-cards. AntiFraud systems allow for certain statistics about the behavior of a real person on the network and compare them with the "behavior" of the SIM-card. It is known that mobile operators are beginning to follow the subscriber number from the activation date.
GoAntiFraud will allow you to minimize the risks of the SIM-lock in the GSM termination. Reduce business costs on the purchase of new SIM-cards by buying the service license and you will get more profit!
Assessing the SIM-card, the system takes the following parameters into account:
Both the parameters and their numerical values change depending on the mobile operator and country in which the calls are terminated.
To work around Antifraud systems, terminators use different methods to simulate the behavior of a real user on the network. GoAntiFraud will help you build an efficient GSM termination logic. We offer proven masking tools for SIM-cards and use software for the computerized control of the voip gsm gateway. Our service also helps circumvent the calling by the operator, thanks to the "white" and "black" lists function.
