The provision of lawful interception is a requirement of national law, which is usually mandatory. Fromtime to time, a NWO and/or SvP and/or AP will be required, according to a lawful authorization, to make availableresults of interception, relating to specific identities, to a specific Law Enforcement Agency (LEA).The general approach of the HI described in the present document is to be applied for every network technique, presentor future, as long as the intercept requirements can be satisfied.
