example 1

[0112] example 1 : Default SRI_SMS ruleset

[0113] Separate rules executed in sequence

[0114] Network address consistency rule (SUSPECT (suspect))

[0115] Prohibited / Trusted Network Rules (SPAM / GOOD (SPAM / GOOD))

[0116] Volume Threshold Rules - Per Sent Network (SUSPECT)

[0117] Volume Threshold Rules - Across All Networks (SUSPECT)

[0118] Called Party Address Proximity Rule (SUSPECT)

[0119] If any of the above rules are violated, the message is marked as indicated above and no further rules are evaluated. If there is an application error in evaluating a rule, the error will be logged, but the rule will be ignored for spam filtering purposes. Execution continues in the above order for the next rule. If none of these rules are violated, the message is marked as GOOD. It should be noted that it is also possible to mark a message as GOOD when it comes from a trusted source.

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.

Description

Background of the invention [0001] The present invention relates to a method and apparatus for implementing short message service (SMS) spam (SPAM) filtering. Embodiments described herein integrate policy management into spam filtering rules in order to enhance SMS anti-spam mechanisms. [0002] While the present invention is, and will therefore be described with particular reference to, the field of SMS spam filtering, it will be appreciated that the invention may find use in other fields and applications as well. For example, the teachings of the presently described embodiments can be applied to other types of spam filtering. [0003] By way of background, with the increasing use of the Internet, it is relatively easy for senders to send messages to a large number of destinations at little or no cost. The same is true for messages sent via Short Message Service (SMS) in wireless network systems. In many cases, when the sender is a third-party solicitor or marketer, these ...
