Temporary Block Flow

A Temporary Block Flow is a physical connection used by the two RR (Radio Resource) entities to support the unidirectional transfer of LLC (Logical Link Control) PDU (Protocol Data Unit) on packet data physical channels. A TBF is temporary and is maintained only for the duration of the data transfer, i.e. until there are no more RLC (Radio Link Control) / MAC (Medium Access Control) blocks to be transmitted.
