Abstract: A filtering and application triggering platform may be implemented on a signaling message routing node to decode signaling messages and increase efficiency in subsequent processing of the signaling message. A communications link module on a signaling message routing node receives a signaling message. A first filtering and application triggering module associated with the communication link module extracts predetermined parameters from the signaling message and generates a decode key based on the parameters. The first filtering and application triggering module applies a first triggering rule to the decode key and determines whether to forward or drop the message. If the first filtering and application triggering module determines that the message should be forwarded, the first filtering and application triggering module forwards the message to another processing module within the signaling message routing node. The decode key is forwarded along with the message.

Abstract: Methods, systems, and computer program products are disclosed for preventing the delivery of unwanted SMS messages, such as those containing unsolicited commercial messages or spam, in a communications network. More particularly, SMS messages are intercepted prior to delivery and at least a portion of the SMS message content is encapsulated within an electronic mail (e-mail) message. The e-mail message is communicated to an e-mail spam filtering resource in a data network, where spam screening/filtering algorithms are applied. The e-mail message is discarded at the e-mail spam filtering resource if the message fails spam screening. Alternatively, or in addition, the results of the spam screening may be returned with the original message for another network node to process accordingly. In any case, if the message passes spam screening, the original SMS message that is associated with the e-mail message may be delivered to/toward the intended message recipient.
