Laws of individual nations and regional institutions (e.g. European Union), and sometimes licensing and operating conditions define a need to intercept telecommunications traffic and related information in modern telecommunications systems. It has to be noted that lawful interception shall always be done in accordance with the applicable national or regional laws and technical regulations.

This TS describes the service requirements from a Law Enforcement point of view only. The aim of this document is to define an interception system for 3GPP networks that supports a number of regional interception regulations, but these regulations are not repeated here as they vary. Regional interception requirements shall rely on this specification to derive such information as they require.

These interception requirements shall be used to derive specific network requirements.
