This TS describes the architecture and functional requirements within a Third Generation Mobile
Communication System (3GMS) and the Evolved Packet System (EPS).
This document describes in general the architecture and functions for lawful interception.
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.
The specification shows the service requirements from a Law Enforcement point of view only. The aim of this
document is to define a 3GMS and EPS interception system that supports a number of regional interception regulations, but these regulations are not repeated here as they vary. Regional interception requirements shall be met in using specific (regional) mediation functions allowing only required information to be transported.
