[RRC Protocol ]

25.331/7.1

The RRC connection is defined as a point-to-point bi-directional connection between RRC peer entities in the UE and the UTRAN characterised by the allocation of a U-RNTI. A UE has either zero or one RRC connection.

-- RRC connection UE( ) UTRAN( )

-- RRC connection U-RNTI
