Original Abstract Submitted

A network mediation device () in a communication network () receives application-layer control messages () intercepted in the communication network () as part of a lawful interception service. Each of the application-layer control messages () received is configurable to include (i) a session identity field () indicating an identity of an application-layer control session () to which the application-layer control message belongs: and (ii) one or more linking fields () that link the identified application-layer control session () with another application-layer control session (). The network mediation device () sends. over a handover interface () from the network mediation device () towards a law enforcement device (), the application-layer control messages () and signaling () indicating which application-layer control messages () belong to application-layer control sessions () that are linked to one another.
