Full Description
ETSI TS 103 120 defines an electronic interface between two systems for the exchange of information relating tothe establishment and management of lawful required action, typically Lawful Interception. Typically this interfacewould be used between: on one side, a Communications Service Provider; and, on the other side, a Government or LawEnforcement Agency who is entitled to request a lawful action. The present document is a specific and detailed exampleof one particular Warrantry interface for eWarrants [i.1].The ETSI reference model for LI (ETSI TS 101 671 [1] or ETSI TS 102 232-1 [2]) defines three interfaces between lawenforcement and CSPs, called HI-1, HI-2 and HI-3. The protocol defined in the present document is designed to providea large part of the functionality for HI-1. It is not designed to be used for HI-2 (delivery of intercept related information)or HI-3 (delivery of communications content). The protocol designed in the present document may also be used forinterfaces which require structured exchange of information relating to the establishment and management of LawfulInterception. The general view is that the HI-1 concept can also be used for other legal actions than LI. For that reasonthe present document could, besides LI, also be applied for retained data requests, seized data requests, datapreservation orders and other similar legal requests.
