Abstract: Methods and systems are presented for filtering spam MAP SMS messages in an SS7 network, including mobile originated and mobile terminated MAP SMS messaging to mitigate spam-related traffic in the SS7 network. The system includes an anti-spam application (42) running on one or more network servers (40) that receives the MAP messages before routing to any SMSC or MSC, and classify these as spam or good. The good MAP SMS messages are then provided to the corresponding destinations by appropriate SMSC or MSC in the SS7 network, while the spam MAP SMS messages are not delivered to the SMSC.

Abstract: Spam filtering methods and systems are provided for filtering spam SMS SMPP messages from an ESME to an SMSC associated with a wireless network, in which an anti-spam application receives SMPP SMS messages from the ESME and performs spam filtering prior to providing SMPP messages to the wireless network, with good messages being forwarded to the SMSC of the network and spam messages being discarded or persisted.

Abstract: A method and apparatus for implementing short message service (SMS) SPAM filtering is provided. The embodiments described herein integrate policy management into spam message filtering rules to enhance an SMS anti-spam mechanism.

Abstract: This invention relates to methods and apparatus for storing short message service (SMS) and e-mail messages for detecting sources of spam messages and especially spam messages for fraud or pornographic purposes. Since storage of critical messages may be required for longer intervals and since the amount of spam message traffic is large, it is impractical to store all suspected spam messages for the maximum interval required for anti-fraud purposes. Accordingly, under the control of an anti-spam bureau, different classes of actual spam, suspected spam, and non-spam messages are stored in different subfiles; each subfile can have a different retention period and percentage of suspected spam messages to be stored; the amount of storage for ones of the subfiles and the retention period can also be modified under the control of the anti-spam bureau.
