    Abstract: A terminal for transmitting a signal in a wireless communication system is provided. The terminal includes a transceiver, and at least one processor configured to start a timer when a Radio Resource Control (RRC) connection establishment procedure or an RRC connection resume procedure is initiated, identify that the timer is expired or that, while the timer is running, an integrity check failure indication is received from a lower layer, determine whether at least one of a first condition or a second condition is met, the first condition including a condition that the terminal has connection failure information available in an information container and a registered Public Land Mobile Network (PLMN) does not correspond to a PLMN identity included in the information container, and the second condition including a condition that a first cell identity of a current cell is not equal to a second cell identity stored in measurement result information about a cell where connection failure happened, in response to determining that at least one of the first condition or the second condition is met, set a count number about connection failure included in the information container to 0, and after determining whether at least one of the first condition or the second condition is met, clear contents included in the information container except for the count number about the connection failure.

    Abstract: The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, health care, digital education, retail business, a security and security-related service, etc.) on the basis of 5G communication technology and IoT-related technology. The present disclosure discloses a method and a device for controlling the RRC state mismatch issue of a terminal, and also discloses a method and a device for providing access control configuration information of a terminal.
