MGCOMM SMS Firewall Capabilities

  • Advanced Message Filtering

Operator revenues suffer when unwanted messages are sent to its subscribers. Customer satisfaction decreases, and the operator itself is often left without compensation for the delivery of a message. MGCOMM SMS Firewall provides the ability to control incoming traffic with its extensive and highly configurable filtering capabilities. Messages are examined using a versatile rule-based logic to determine whether they will be delivered to a subscriber or not. An array of parameters can be inspected by MGCOMM SMS Firewall, including the message content itself, to block messages from certain sources and messages containing suspicious links and telephone numbers. It can also be used to block A2P and M2M traffic from operators that do not pay termination fees while allowing regular subscriber traffic from the very same operators.

  • Active Prevention of Faking

Due to the popularity of SMS, many senders use subversive methods to avoid paying for the messages they send. This leads to revenue loss for the receiving operator. Illicit senders of SMS sometimes use a method called SMSC faking to be able to send messages free of charge. With this method, the sending SMSC uses a fake address when transmitting messages to avoid being charged termination fees by the receiving network. MGCOMM SMS Firewall detects and intercepts messages sent from SMSCs that fake their addresses. Detection takes place before the delivery so that no messages from such SMSCs reach their destination.

  • Message Quota Control

Message flooding is another challenge facing operators. Excessive amounts of incoming messages can cause customer dissatisfaction and network overload. To prevent message floods from foreign network, MGCOMM SMS Firewall can be configured to enforce quota controls. The quota control feature keeps track of the number of incoming messages and automatically blocks traffic if there are too many messages arriving from a certain MSISDN. Repetitive content from a single origin can also be filtered to effectively prevent spam.

  • Virtual SMS Firewall Functionality

MGCOMM SMS Firewall allows operators to consolidate their SMS operations for multiple countries in one messaging node. To support consolidation, a single hardware cluster can operate several virtual firewall nodes, each with its own configuration, including global title and routing profiles. This allows for services to be separated by territory, service, type, volume or service level.

  • SIM Farm Filter

Another threat to the business of operators is SIM farms, that use bundles with large or unlimited numbers of text messages to distribute enterprise messages. MGCOMM SMS Firewall can efficiently block traffic from such players through traffic analysis.
