System for intercept of wireless communications

Abstract

A system for the intercept of wireless communications provides that a HLR of a wireless communications system includes one or more flags associated with each subscriber, and the HLR notifies an intercept server each time a call event is detected in the HLR for a subscriber under surveillance as indicated by the flags. The intercept server includes a Gateway Delivery Function module and one or more Delivery Function modules, wherein the Gateway Delivery Function module provisions the Delivery Function modules depending on the location of the suscriber, to deliver call content or data from an MSC to a collection function operated by a law enforcement agency. Non-call associated data is also provided to a Delivery Function module for delivery to a Collection Function.

Dependencies are inferred from the claim text.
