Meanwhile, a UE can attach to a specific cell, from which it receives a service. In case of an uplink (UL), the MAC layer sends the dedicated control information to the physical layer as part of the user data stream. The MAC layer is responsible for multiplexing the user data stream through flow control and scrambling for modulation and coding. In case of a downlink (DL), the MAC layer controls the physical layer to provide transmission services to UEs. The control of the MAC and PHY is carried out by a radio network controller (RNC) through layer-3 information.
A RNC controls its associated Node Bs by controlling its MAC and physical layer (PHY) to provide a service to UEs by allocating radio resources and controlling handover. The present invention relates to a mobile communication system and a method of performing handover, and more particularly, to a mobile communication system and a method of performing handover from a cell in which a signal from a user equipment (UE) cannot be received to another cell in which the signal from the UE can be received.Ī Universal Mobile Telecommunication Service (UMTS) Terrestrial Radio Access Network (UTRAN) mainly includes a plurality of radio network controllers (RNCs), Node Bs, and user equipments (UEs).
