name: MDF
full_form: Mediation and Delivery Function
context: The MDF shall populate the TargetIdentifiers field of the IRIPayload defined in Annex A with all Target Identifiers available at the MDF. For all Identifiers received in the LI_X2 "Matched Target Identifier" conditional attribute (see clause 5.3.2), the MDF shall include the relevant Identifier with the provenance set to "matchedOn". For all Identifiers received in the the LI_X2 "Other Target Identifier" conditional attribute (see clause 5.3.2), the MDF shall include the relevant Identifier with the provenance set to "other". For all Identifiers present in the xIRI payload, the MDF shall include the relevant Identifier with the provenance set to "observed". For all Identifiers present in the provisioning message received over X1, the MDF shall include the relevant Identifier with the provenance set to "lEAProvided". For all Identifiers present in the MDF that are not reported as other TargetIdentifiers, the MDF shall include the relevant Identifier with the provenance set to "other".
description: The Mediation and Delivery Function (MDF) is a network component responsible for mediating and delivering Lawful Interception (LI) information between different network elements. It plays a crucial role in the LI architecture, handling tasks such as populating Target Identifiers fields and managing identifier provenance.
explanation: The MDF is classified as a Network Function based on its role in mediating and delivering LI information within the network, as highlighted by the context from 3GPP TS 33.128.
