ETSI - ES 201 671

Telecommunications Security; Lawful Interception (LI); Handover Interface for the Lawful Interception of Telecommunications Traffic

inactive
Organization: ETSI
Publication Date: 1 May 1999
Status: inactive
Page Count: 105
scope:

The present document is step 3 of a three step approach to describe a generic handover interface for the provision of lawful interception from a Network Operator, an Access Provider or a Service Provider (NWO/AP/SvP) to the Law Enforcement Agencies (LEAs). The provision of lawful interception is a requirement of national law, which is usually mandatory for the operation of any telecommunication service. The aim of the present document is also to fulfil the user requirements for a future mutual assistance between the LEAs of different countries.

Interworking with other countries than those following the present document is for further study.

Step 1 contains the requirements for lawful interception from a users (LEAs) point of view and is published as ETR 331 [1].

The derived network functions and the general architecture (or functional model) is described in the step 2 document, ES 201 158 [2].

The present document specifies the generic flow of information as well as the procedures and information elements, which are applicable to any future telecommunication network or service.

The standard specifies in detail network/service specific protocols relating to the provision of lawful interception at the handover interface, for the following networks/services:

  • speech;
  • circuit and packet switched data;
  • UMTS and similar services.

NOTE: As there are several types of new networks and/or services currently being developed, the present document will subsequently be expanded as soon as the relevant standards will be available as stable drafts. The revisions of the present document, containing these amendments in additional sections, will be published.

Version 1.1.1 will be limited to 64 kbit/s for circuit switched content of communication and certain packetized services.

Where applicable, the present document bases on other ETSI standards or ITU-T Recommendations in the area of telecommunication services. The reader should be familiar with the referenced standards/recommendations, including the ITU Recommendations, which are endorsed by many of the referenced ETSI standards.
