Claim 7:
8. A user equipment (UE) in wireless communication system, the UE comprising:
a transceiver; and
a controller configured to:
transmit, to a base station, a radio resource control (RRC) connection resume request message for a current cell, while the UE is in an RRC inactive state,
start a T319 timer, upon the transmission of the RRC connection resume request message, and
based on an expiration of the T319 timer:
identify whether a cell ID of the current cell is equal to a cell ID of a cell associated with stored connection resume failure information,
in case that the cell ID of the current cell is not equal to the cell ID of the cell associated with the stored connection resume failure information, reset a number of consecutive failures to an initial value, and
store connection resume failure information associated with the current cell,

wherein the number of consecutive failures indicates a number of consecutive failed RRC resume procedures in a same cell.
