Abstract

A Lawful Intercept (LI) system and a method in a LI system comprising at least one Intercept Access Point (IAP) for intercepting communication traffic using User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) packets in one or more communications networks. The IAP delivers the communication traffic as Communication Content (CC) to a Law Enforcement Agency (LEA) via a mediation functionality controlled by an administration functionality. The method comprises receiving CC as UDP and TCP; storing UDP and TCP CC in a buffer arrangement; and forwarding TCP CC or UDP CC via a first CC handover interface or via a second CC handover interface, separated from the first CC handover interface, to the LEA. A synchronization mechanism is provided in order to retransmit all IP packets lost over the new interface and a buffer capacity process.
