scope:

The present document defines an architecture for the lawful interception of dynamically-allocated flows in a secondary communications domain, triggered by the activity of permanent identities in a primary domain.

Dynamic triggering as defined in the present document is intended to be able to handle a service that is handled by more than one CSP or network (for example one CSP handling the communication set up and another CSP handling the content exchange).

The present document is applicable only where national legal frameworks permit it. Issues concerning national legal frameworks are out of scope.
