An access control method of a terminal in a wireless communication system, the method comprising: receiving a request for a radio resource control, RRC, connection establishment from an upper layer; determining whether to apply an extended access barring, EAB, to the request for the RRC connection establishment by: applying, if the RRC connection establishment corresponds to an access attempt to receive a call, an access class barring, ACB, to the request for the RRC connection establishment without applying the EAB, wherein ACB information is received via a system information block from an evolved Node B, eNB; and applying (417, 419), if the RRC connection establishment corresponds to a Cause, the EAB first to the request for the RRC connection establishment, and then applying the ACB when the access is not barred due to EAB, wherein ACB and EAB information is received via system information blocks from the eNB; wherein the Cause comprises at least one of: a case where the terminal performs an access attempt to make a call to transmit data; a case where the terminal performs an access attempt to make a call to transmit a control message; and a case where the terminal performs an access attempt to make a call irrespective of a transmission delay. receiving a request for a radio resource control, RRC, connection establishment from an upper layer; determining whether to apply an extended access barring, EAB, to the request for the RRC connection establishment by: applying, if the RRC connection establishment corresponds to an access attempt to receive a call, an access class barring, ACB, to the request for the RRC connection establishment without applying the EAB, wherein ACB information is received via a system information block from an evolved Node B, eNB; and applying (417, 419), if the RRC connection establishment corresponds to a Cause, the EAB first to the request for the RRC connection establishment, and then applying the ACB when the access is not barred due to EAB, wherein ACB and EAB information is received via system information blocks from the eNB; wherein the Cause comprises at least one of: a case where the terminal performs an access attempt to make a call to transmit data; a case where the terminal performs an access attempt to make a call to transmit a control message; and a case where the terminal performs an access attempt to make a call irrespective of a transmission delay. applying, if the RRC connection establishment corresponds to an access attempt to receive a call, an access class barring, ACB, to the request for the RRC connection establishment without applying the EAB, wherein ACB information is received via a system information block from an evolved Node B, eNB; and applying (417, 419), if the RRC connection establishment corresponds to a Cause, the EAB first to the request for the RRC connection establishment, and then applying the ACB when the access is not barred due to EAB, wherein ACB and EAB information is received via system information blocks from the eNB; wherein the Cause comprises at least one of: a case where the terminal performs an access attempt to make a call to transmit data; a case where the terminal performs an access attempt to make a call to transmit a control message; and a case where the terminal performs an access attempt to make a call irrespective of a transmission delay. a case where the terminal performs an access attempt to make a call to transmit data; a case where the terminal performs an access attempt to make a call to transmit a control message; and a case where the terminal performs an access attempt to make a call irrespective of a transmission delay.
