Abstract
In a telecommunications network, method and apparatus for blocking unwanted messages (spam). Messages are first examined by a fast process which uses rules and data tables to determine whether a message can be passed or is potentially a spam message. If the message is potentially a spam message, the message content is analyzed by a deep process. Advantageously, most messages can be passed or blocked quickly and extensive data processing is required only for the few messages which cannot be categorized by the fast process.
