name: MRB
full_form: Media Resource Broker
context: UE test loop mode C is mandatory for NR UEs supporting MBS. UE test loop mode C provides counting of successfully received MBS Packets on one MRB (Multicast MRB or Broadcast MRB) while UE is operating in NR/5GC. - For Multicast MRB configuration: - Multicast MRB with DL only RLC-UM or bidirectional RLC-UM configuration for PTP transmission; - Multicast MRB with RLC-AM entity configuration for PTP transmission; - Multicast MRB with DL only RLC-UM entity for PTM transmission; - Multicast MRB with two RLC-UM entities, one DL only RLC-UM entity for PTP transmission and the other DL only RLC-UM entity for PTM transmission; - Multicast MRB with three RLC-UM entities, one DL RLC-UM entity and one UL RLC-UM entity for PTP transmission and the other DL only RLC-UM entity for PTM transmission; - Multicast MRB with two RLC entities, one RLC-AM entity for PTP transmission and the other DL only RLC-UM entity for PTM transmission. - For Broadcast MRB configuration: - Broadcast MRB with one DL only
description: The Media Resource Broker (MRB) is a network function responsible for managing and controlling media resources within the network, including multicast and broadcast transmissions. It plays a crucial role in ensuring efficient use of network resources and providing quality of service for various types of transmissions.
explanation: MRB is classified as a Network Function because it manages and controls media resources within a network, directly impacting how data flows and is delivered.
