摘要:
Method and apparatus for conducting surveillance in a SS7 Intelligent Network (IN) or Advanced Intelligent Network (AIN) provides in the case of AIN that an Info Analyzed trigger is armed in an end office switch and notifies a delivery function when a call is processed. The delivery function instructs the end office switch to forward the call to the delivery function, where it is accessed for monitoring forwarded back to the end office switch. A similar method is used to process calls received by the SUS. In the case of IN, the identity of a line card assigned to a subscriber under surveillance (SUS) is changed to a number dedicated to surveillance subjects. Calls originated by the SUS are forwarded to a delivery function, which identifies the SUS based on the dedicated number of the calling party, intercepts call content, and forwards the call back to the end office switch with the called party id aid the original number and id of the SUS. The end office switch then completes the call. A similar method is used to process calls received by the SUS.
摘要:
A system, method, and apparatus for intercepting data streams such as packets on a network. In one embodiment, the method includes: receiving at a network surveillance system (NSS), a target to be intercepted on the network; creating a target identification (target ID) for the target, wherein the target ID is unique to the NSS in order to track data streams of the target during subsequent processing, such as extraction of content and metadata, in the NSS; intercepting the data streams of the target on the network; tagging the data streams of the target that are intercepted from the network with a respective target ID; transmitting the data streams of the target to the NSS for subsequent analysis; and distributing the data streams across a scalable quantity of data processing engines in the NSS.

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.
