A method for lawful interception of communication related information is disclosed. In the preferred embodiment, the method includes detecting the occurrence of an event in a packet data network. The method also includes collecting communication related information of a communication in the packet data network in response to the detection of the event based at least in part on the detected event and providing the collected communication related information to one or more law enforcement agencies.

System and method for reporting communication related information in a packet mode communication

A method and apparatus are provided for extracting and reporting communication associated information of communications between a subject and an associate. This is achieved by populating an application identifier in the Network Layer 3, which the access networks examine in order to route the packets appropriately, and, thereby, allowing the access networks to isolate and extract the communication associated information. The access networks extract the call associated information and report the same to the Law Enforcement Agencies. Delivery to the LEAs of communication associated information may also be optimized.

Lawful communication interception&#x2014;intercepting communication associated information

An apparatus, system and method for call forwarding when roaming from a first type network, such as an ANSI-41 cellular network, to a second type network, such as a GSM cellular network. According to one embodiment of the present invention, a signaling message converter signals an originating MSC in a local communication system to redirect a call when a terminating foreign MSC cannot terminate the call due to predetermined circumstances.
