name: SRB
full_form: Signalling Radio Bearer
context: The UE releases the MBMS RB by using one of the following mechanisms: - Explicit MBMS RB Release - Implicit MBMS RB Release The Explicit MBMS RB Release mechanism allows UTRAN to explicitly indicate to MBMS UEs that an MBMS Radio Bearer should be released. For p-t-m transmissions the Explicit MBMS RB Release indication is contained within the MBMS SERVICE INFORMATION signalling flow. For p-t-p transmission the release of MBMS radio bearers is completed in the same way as for a non-MBMS radio bearer. If the Explicit MBMS RB Release indication is received, the UE releases the MBMS RB. The Implicit MBMS RB Release mechanism applies only to p-t-m transmission and enables a UE to release the MBMS Radio Bearer without receiving the Explicit MBMS RB Release. The UE identifies Implicit MBMS RB release if it detects that the RB is not present in the MBMS SERVICE INFORMATION signalling flow.
description: Signalling Radio Bearer (SRB) is a specific channel within the radio access network dedicated to transmitting control plane information like RRC PDUs. It plays a crucial role in supporting split SRB configurations across various Multi-RAT Dual Connectivity (MR-DC) scenarios and its setup is managed through Mobility Node (MN) during Secondary Node Addition and/or Modification procedures.
explanation: SRB is categorized as a Channel because it represents a dedicated communication pathway for signalling information between the User Equipment (UE) and the network. The context explicitly mentions SRB's function in transmitting control plane data, such as RRC PDUs, further solidifying its classification as a channel.
