Meetings
SA3-LI has several meetings per year. It follows the
overall 3GPP release schema to support new features.
Interaction with the various other 3GPP groups is common.
Delegates in SA3-LI represent
LEAs,
CSPs,
network vendors and lawful interception vendors.
Published specifications
Next generation of TS 33.108, introduces support for LI
on 5G networks. In this new generation, the HI2/HI3
interfaces have been delegated to
ETSI TS 102 232-7.
Additionally, network vendors are now expected to
implement the standardized X1/X2/X3 interfaces as
defined in
ETSI TS 103 221.

3GPP website.
Next generation of TS 33.107. Various new concepts have
been introduced, specifically around the more dynamic and
flexible nature of virtualisation.
Download the latest version from the
3GPP website.
Similar to TS 33.106 and essentially the "next generation"
of LI requirements. Specifically, requirements around
security and virtualisation have a major impact to the
architecture.

3GPP website.
Defines the HI2/HI3 interfaces used for 2G, 3G, 4G mobile
data interception, CS
services, IMS and several other services.

3GPP website.
Note that this specification is becoming less important
since the publication of 3GPP TS 33.128.
3GPP TS 33.107: LI architecture
Defines the overall LI architecture for the services supported
in TS 33.108. Also defines that a (typically proprietary) X2/X3
implementation is mandatory for implementation by the network
vendors.

3GPP website.
3GPP TS 33.106: LI requirements
Defines the overall LI requirements in a 3GPP context.
