Method and apparatus for paging terminal in a light connection state in wireless communication system

A user equipment (UE) in a light connection state in a wireless communication system, the UE comprising:

• a memory;
• a transceiver;
• and
• a processor, operably coupled to the memory and the transceiver, that:
• while being in a first state, controls the transceiver to receive a cell radio network temporary identity (C-RNTI) from a first cell,
• enters from the first state to a second state,
• while being in the second state, moves to a second cell,
• during a random access procedure, controls the transceiver to receive a random access response including a temporary C-RNTI from the second cell, and
• controls the transceiver to replace the C-RNTI received from the first cell with the temporary C-RNTI included in the random access response,
• wherein the first state is a RRC_CONNECTED state,
• wherein the second state is the light connection state, which is either a substate of the RRC_CONNECTED state or a different state than the RRC_CONNECTED state, and
• wherein, in the second state, the UE is allowed to move autonomously across a plurality of cells without a handover procedure controlled by a network.
