It is located above the Radio Link Control (RLC), a layer 2 responsible for mapping logical channels. It is similar to 802.11's LLC layer which supports multimode operations and it works in three different modes: a) Transparent b) Unacknowledged data transfer c) Acknowledged data transfer. Its main function is to deliver \"Cell Broadcast\" messages to its upper layer such as NAS. Other functions specified in [3GPP TS 25.301] are: \n* Storage of Cell Broadcast Messages. \n* Traffic volume monitoring and radio resource request for CBS. \n* Scheduling of BMC messages. \n* Transmission of BMC messages to UE. \n* Delivery of Cell Broadcast messages to upper layer (NAS). Except for broadcast/multicast it operates in transparent mode as per [BMC-STD]. On the uplink BMC it requires Unacknowledged mode of data transfer from RLC."@en . . .
