context: and P2P with DCMF/enhanced MRF case of application data channel (application data channel between UE and UE in remote IMS as showed in the figure 6.4.2.1-1), the DCMF/enhanced MRF is proposed to terminate DTLS protecting with UE. In the P2P without DCMF/enhanced MRF case, the IMS-AGW is responsible for terminate DTLS protecting with UE. The protection between DCMF/enhanced MRF and DCSF can be TLS or DTLS which depends on the underlying protocols, i.e., UDP or TCP. Figure 6.4.2.1-1: IMS supporting DC usage with DCMF (see TS 23.700-87 [2], clause 6.20.1.2) NOTE: The protocols between DCMF/DCSF and DC application server are out of scope of this study. The DTLS between UE and the IMS is established based on the certificate fingerprints exchanged over SDP. To ensure the integrity of the certificate fingerprint the signalling path is assumed to be protected. In case the DTLS is between UE and DCMF/enhanced MRF, the P-CSCF should include the certificate fingerprint of the DCMF/enhanced MRF
description: The Media Resource Function (MRF) is a network function responsible for managing and controlling media resources within the IMS (IP Multimedia Subsystem). It plays a crucial role in peer-to-peer (P2P) communications, particularly in scenarios involving DTLS (Datagram Transport Layer Security) protection between UEs (User Equipment) and the MRF itself. The MRF is also involved in terminating DTLS connections with UEs and ensuring the integrity of certificate fingerprints exchanged over SDP (Session Description Protocol).
explanation: The context describes the MRF's role in managing media resources, handling P2P communications, and ensuring security through DTLS protection. These functions are characteristic of a Network Function, which is a component responsible for controlling and managing network operations.
