Abstract: The present invention relates to a method and apparatus for efficiently controlling access for system load adjustment in mobile communication systems. In a wireless communication system according to one embodiment, the method for transmitting and receiving data by a terminal including a user equipment (UE) non access stratum (NAS) and a UE access stratum (AS) includes the steps of: receiving by the UE AE, information including emergency call-related information which includes barring information by type for the emergency call, from a base station; transmitting, by the UE NAS, a service request for the emergency call to the UE AS; and determining, by the UE AS, whether to bar the service request on the basis of emergency call-related information. According to one embodiment, during the emergency call transmission, network congestion can be easily controlled by enabling various types of emergency calls to be transmitted, and enabling access to be barred information according to the situation of a communication network and types of emergency calls. Also, even when a specific type of emergency call is barred from access, the terminal can change to another type of emergency call and try for access. Therefore, it is effective in that an emergency call can be transmitted in various schemes even in a state where the network is congested.

Abstract: A method for transmitting a channel state by a terminal in a communication system, according to one embodiment, comprises the steps of: receiving discontinuous reception (DRX) configuration information from a base station; determining whether the terminal is set to transmit channel state information only in onDuration according to a DRX operation; determining whether an arbitrary subframe to be received is a subframe included in onDuration if the terminal is set to transmit the channel state information only in onDuration according to the configuration; and not transmitting the channel state information on the arbitrary subframe if the arbitrary subframe is not a subframe included in onDuration. According to the embodiment, the terminal can efficiently report channel state information.

Abstract: The present invention relates to a method and an apparatus for logging a radio resource control (RRC) failure of user equipment (UE) and receiving the log. According to one embodiment of the present invention, a method for logging an RRC failure of UE may comprise the steps of: attempting random access; if the failure of random access is sensed, logging information on the failure; and if the success of random access is sensed, transmitting information on the failure logged before the success to a connected base station. According to one embodiment of the present invention, an apparatus and a method which effectively log a channel state or a connection failure can be provided.
