A communications traffic acceptance control methods and a Protocol Data Unit (PDU) filtering gateway are presented. The PDU filtering gateway operates in accordance with a group of sentry filtering rules and on accepting PDU traffic. The enhanced PDU filtering gateway selectively generates at run-time additional dynamic filtering rules. Dynamic PDU acceptance control may be enforced on communications traffic in the same and/or the opposite conveyance direction as the first sentry filtering rule triggering PDU. Dynamic PDU acceptance control may also provide time constraint enforcement on traffic acceptance. Advantages are derived from a dynamic PDU acceptance control over connection establishment utilizing reduced resources. New data services may be accommodated via sentry filtering rule specifications providing resilience to equipment obsolescence and minimizing code maintenance overheads.
