Abstract:
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 at least a parameter value in data for which lawful interception or data retention has been activated; based on said at least one parameter value, evaluating whether said traffic is going to be intercepted or retained at a second node crossed by said traffic, the second node being in the same network as and downstream from the first node; and filtering out lawful interception requests or intercepted data when said traffic is going to be intercepted or retained at the second node; and fulfilling the lawful interception requests when said traffic is not going to be intercepted or retained at the second node.
