22、llowed in ETSI deliverables except when used in direct citation. Introduction Originally ETSI ETR 331 i.1 was intended to incorporate into ETSI standards the EU Council Resolution of 1995 1 on International User Requirements. In consequence, the original ETSI ETR 331 i.1 concentrated on telephony ne

23、tworks such as PSTN, ISDN and GSM because these were the main telecommunications networks. The introduction of TETRA, GPRS, UMTS and the increased usage of the Internet forced a change so that ETSI ETR 331 i.1 has been replaced by the present document which focuses on the interpretation of ETSI ETR

24、331 i.1 on specific technologies in the different annexes. According to rules set by the laws of individual nations as well as decisions of the European Union, there is a need to lawfully intercept telecommunications traffic and intercept related information in modern telecommunications systems. Wit

25、h the aim of harmonising the interception policy in the member states, the Council of the European Union adopted a set of requirements in EU Council Resolution of 1995 1, with the aim of feeding them into national legislation. The LEA requirements have to be taken into account in defining the abstra

26、ct handover interface. The definition of a handover interface for the delivery of the results of lawful interception should allow the technical facilities to be provided: - with reliability; - with accuracy; - at low cost; - with minimum disruption; - most speedily; - in a secure manner; - using sta

27、ndard procedures. ETSI ETSI TS 101 331 V1.5.1 (2017-03)6 1 Scope The present document gives guidance for lawful interception of telecommunications in the area of co-operation by network operators, access providers, and service providers. It provides a set of requirements relating to handover interfa

28、ces for the interception by law enforcement and state security agencies. Requirements with regard to telecommunications services provided from areas outside national boundaries are not fully developed yet and therefore only some preliminary requirements have been annexed for information. The present

29、 document describes the requirements from a Law Enforcement Agencys (LEAs) point of view. Not all requirements necessarily apply in one individual nation. These requirements need to be used to derive specific network requirements and furthermore to standardize handover interfaces. 2 References 2.1 N
