33.1083G Security3GPPHandover interface for Lawful Interception (LI)Release 17TS

A.3.1 General

Functions having an HI2 interface may support the use of ETSI TS 102 232-1 [104] and ETSI TS 102 232-7 [105] to realise the interface.

In the event of a conflict between either specification and the present document, the terms of the present document shall apply.

A.3.2 Usage for realising HI2

The IRI messages sent over HI2 are structured as a header and a payload. The header contains general information like LIID, timestamp, correlation information (as for example defined in ETSI TS 102 232-1 [104]). The payload contains intercept related information based on information that the MF has received from sources in the network. Messages defined as passing over the HI2 interface shall be passed as described in ETSI TS 102 232-7 [105] clauses 5 and 6.
