Central European mobile subscribers are to get enhanced protection against SMS fraud thanks to a major upgrade at the core of the Telekom network by text and voice vendor Telsis.

An enhanced anti-fraud system will give increased capacity for spotting and trapping SMS spoof* attempts, as well as provide added insurance for Telekom against pre-pay revenue leakage.

Telekom Deutschland already provides anti-spoof services to sister operators in Austria and the Czech Republic, having extended its original Telsis solution in 2006 to cover its two neighbours just a year after installation.

The Telsis system carries out multiple real-time checks on inbound text messages Telekom receives over an international interconnect. It rejects any messages that come from spoofed origination addresses, protecting legitimate subscribers from spam and inflated bills – and the network itself from revenue loss and overload caused by serial fraud attempts.

Now the system is being upgraded to the latest Telsis software release, as well as being migrated to commercial off-the-shelf blade servers. The increased capacity and processing speed will enable Telekom to continue to provide protection as subscriber numbers grow, as well as turn off a further source of revenue leakage by moving to instantaneous debiting of pre-pay balances.

Telsis products and services are in use with major mobile and fixed network operators worldwide. Telsis is the global pioneer of architectural innovations for messaging networks that enable mobile operators to offer their customers a range of value added protection, personalisation and archive services. The company delivers high value mobile innovation in the service layer, providing text-based services that are easy to use, compelling, virally promoted, and available to all handsets and all users.

Telsis solutions also include SMS Routing and IN voice platforms, as well as NGN media gateways.

*Note to editors –

SMS spoof is a fraud in the Mobile Originated (MO) SMS message path. Fraudsters gain access to an unprotected SS7 interconnect in a foreign network and inject spam messages with false originating addresses that appear to come from roaming home network subscribers. Phone numbers used will be from number ranges held by target operators and may be live, or unallocated. Targeted networks see network load increase but are unable to collect any revenue for these messages. At the same time, their subscribers can be annoyed by spam – and sometimes erroneously billed for it. Both outcomes damage customer relations and brand reputation. The Telsis SMS fraud solution prevents spoof SMS reaching the network.
