name: LI
full_form: Lawful Interception
context: (e.g. LI function's software image) prior to instantiation, see e.g. ETSI NFV-SEC 011 [10] or equivalent. - When required, providing keys to newly instantiated LI functions to enable decryption of LI specific software. - LI functions physical location policy control ensuring LI functions are within the legal location policy of the warrant. - LI Certificate Authority (LI CA, sub-CA of the CSP root CA) for issuing certificates to LI functions as part of their LI provisioning via LI_X0 interface, see clause 5.6.3.2. - Provisioning of all required and valid LI functions instantiated by the CSP network. - Maintaining the master list of all authorised and provisioned LI functions. - Managing the termination of LI instances across all impacted LI functions when the warrant expires or the LEA specifically requests termination of a LI instance. - Certificate revoking when the LI function is terminated or the LI function is de-instantiated. - Maintaining the status of the warrant execution
description: Lawful Interception (LI) refers to the process by which law enforcement agencies can request and obtain access to telecommunications data, such as call records or internet activity, under specific legal conditions. In the context of 3GPP specifications, LI is a critical function that enables authorized interception of communications for legitimate purposes.
explanation: The provided context from 3GPP TS 33.127 highlights the role of Lawful Interception in telecommunications networks, specifically focusing on its functionality and management within the network infrastructure. Given this specific focus on a process rather than a protocol, interface, or network function, it is classified under Miscellaneous.
