Study on Lawful Interception (LI) service in 5G
The present document is a study based on the output (both studies and normative specifications) from other 3GPP groups such as those for 5G Phase 1 as well as issues which arise out of regulatory LI requirements as well LI service specific issues such as those arising from national regulations. Potential solutions will be examined along with considerations of the trade-offs between the solutions will be described. These solutions can include changes to the LI service, architecture and/or stage 3 along.
It is expected that this TR will address stage 1, 2 & 3 aspects, and the completion of each stage’s section will correspond at least to the overall Release 15 schedule with the corresponding start of SA 3 LI stage normative work.
