TRANSPARENT SMS FILTER

With relative ease, spammers can abuse the signaling network with SMS traffic by fabricating and modifying messages. SMS spam, SMS flooding and denial of service (DoS) attacks can cause serious network outages and customer dissatisfaction, which ultimately results in churn.  

The Sevis TSF allows carriers to filter this type of traffic out of their network, before it becomes a problem. It provides comprehensive, granular control of both mobile-terminated (MT) and mobile-originated (MO) SMS traffic. Using a rules-based filtering engine, the TSF determines whether to permit, deny, or modify SMS messages based on both message syntax (formatting) and content (parameters and parameter values). Carriers can now create and deploy customized policies to enforce network-wide rules as well as site-specific rules to protect both customers and the SMS network.  

The Sevis TSF resides on a unique, in-line, network transparent platform--it does not require a point code. This eliminates network re-engineering allowing for rapid system deployment on any ANSI or ITU SS7 link. Scalability is achieved by adding additional TSFs at each site. In-depth failsafe features automatically forward traffic unhindered to the core signaling network even in the unlikely event of a device failure.

CENTRALIZED MANAGEMENT

Centralized provisioning and management of the TSF is provided via an advanced element management system (EMS) enabling carriers to achieve operational efficiencies and lower costs.  Its distributed client/server architecture allows a single graphical user interface to manage all TSFs deployed in the network. The object-oriented methodology of the EMS provides the user with an intuitive way to provision, update and review rules.
