Lawful Interception for Mobile

As with all communications networks, mobile network operators may be required to provide Lawful Interception capabilities for authorized law enforcement agencies. The fact that mobile users may be anywhere in the world means that, in addition to technical considerations, region and international interception regulations have also to be respected.

The work of the 3rd Generation Partnership Project (3GPP™) and the complementary work of ETSI on Lawful Interception is confined to technical matters.

3GPPTM Technical Specification TS 33.106 on the 3GPP website defines the interception requirements for 3rd Generation mobile network based on 3GPPTM specifications, and GSMTM 01.33 on the 3GPP website provides the corresponding information for GSM networks.
