SMPP message processing for SMS spam filtering

摘要

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.
