Abstract: The invention provides a method and system for intercepting at least one session involving at least a first and a second network of different types. For interception both signalling information of the at least one session, and session content related to the same session provided in another of the first and second networks are monitored. An indication to start interception is delivered from one of the first and second networks to the other one of the first and second networks. The first network can be an IP Multimedia Subsystem, IMS, network, and the second network a General Packet Radio Service, GPRS, network.

Abstract: A method for intercepting sessions is provided. The method includes the steps of identifying a packet of a session to be intercepted based on media component information of the session, and, if the packet to be intercepted is identified, providing duplicated packets of the session to an interception management element.
