Lawful Interception (LI); Handover Interface and Service-Specific Details (SSD) for IP delivery; Part 1: Handover specification for IP delivery
|Publication Date:||1 March 2021|
The present document specifies the general aspects of HI2 and HI3 interfaces for handover via IP based networks.
The present document:
• specifies the modular approach used for specifying IP based handover interfaces;
• specifies the header(s) to be added to IRI and CC sent over the HI2 and HI3 interfaces respectively;
• specifies protocols for the transfer of IRI and CC across the handover interfaces;
• specifies protocol profiles for the handover interface.
The present document is designed to be used where appropriate in conjunction with other deliverables that define the service-specific IRI data formats (including ETSI TS 102 227 [i.1], ETSI TS 101 909-20-1 , ETSI TS 101 909-20-2 , ETSI TS 102 232-2 , ETSI TS 102 232-3 , ETSI TS 102 232-4 , ETSI TS 102 232-5 , ETSI TS 102 232-6  and ETSI TS 102 232-7 ). Where possible, the present document aligns with 3GPP TS 33.108  and ETSI TS 101 671  and supports the requirements and capabilities defined in ETSI TS 101 331 [i.9] and ETSI TR 101 944 [i.4].
For the handover of intercepted data within GSM/UMTS PS and CS domains, the present document does not override or supersede any specifications or requirements in 3GPP TS 33.108  and ETSI TS 101 671 .
For the handover of services defined in 3GPP TS 33.128 , in the event of conflict between the present document and 3GPP TS 33.128 , the terms of 3GPP TS 33.128  apply.
