Abstract
A signaling message processing and routing node transmits and receives short message service (SMS) data packets via a communications network. The routing node includes an SMS message discrimination module that determines whether an unwanted or spam SMS message is being sent to a receiving or called party. Unwanted SMS messages are discarded and consequently not delivered to their intended recipient. As a result, mobile subscribers and network nodes are shielded from unwanted SMS traffic. The SMS message discrimination module also includes a provisioning interface that allows end users and network operators to control SMS message discrimination criteria.
