International Classification:

G06F 15/173
G06F 15/16

US Classification:

709224, 709236, 709230

Abstract:

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.
