LAWFUL INTERCEPTION FOR 2G/3G EQUIPMENT INTERWORKING WITH EVOLVED PACKET SYSTEM

摘要

A method, system, and a computer program product for reducing consumption of resources for lawful interception or retention data related to traffic concerning a 2G/3G target mobile connected to a telecommunications network interworking with Evolved Packet System is provided. A first parameter value in traffic for which lawful interception or data retention has been activated is detected at a first node. Based on at least the first parameter value, whether the traffic will be intercepted or retained at a second node crossed by the traffic is evaluated. If the second node will intercept or retain the traffic, the first node foregoes a lawful interception request or retention of intercepted data.

1. A method for reducing consumption of resources for lawful interception or retention data related to traffic concerning a 2G/3G target mobile connected to a telecommunications network interworking with Evolved Packet System, comprising the steps of:
at a first node, detecting a parameter value in traffic for which lawful interception or data retention has been activated; based at least partially on said parameter value, evaluating whether said traffic will cross a second node on which lawful interception or data retention has been activated; and if said traffic will cross the second node on which lawful interception or data retention has been activated, foregoing lawful interception or data retention for the traffic at the first node.
