ETSI - TS 103 462
Lawful Interception (LI); Inter LEMF Handover Interface
|Publication Date:||1 December 2019|
The present document specifies the LEMF to LEMF interface to support (as a minimum) European Investigation Orders (EIOs) related to LI and/or RD. The present document aims to be capable of securely handling real-time and stored data transfer between LEMFs in accordance with ETSI TS 102 232 parts 1  to 7  and the related ETSI TS 133 108  for LI.
In the present document RD is for further study.
Local LI handover interfaces frequently use dedicated networks for delivery with local specific security features. With the EIO Directive in place, there is a need to have a common Handover Interface to allow real-time exchange between LEMFs that can be located in different countries, under different jurisdictions.
