SYSTEM AND METHOD FOR APPLYING EXTENDED ACCESSING BARRING IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. An access control method of a Machine Type Communication (MTC) device in a wireless communication system, the method comprising:
- determining whether a Radio Resource Control (RRC) connection establishment corresponds to a Cause 1 or a Cause 2;
establishing, if the RRC connection establishment corresponds to the Cause 1, the RRC connection so that the RRC connection is not subject to an Extended Access Baring (EAB) procedure; and
determining, if the RRC connection establishment corresponds to the Cause 2, whether to employ the EAB procedure according to an establishment of a System Information Block (SIB) transmitted from an evolved Node B (eNB), and employing the EAB procedure according to the determination.

Abstract
A system and a method that employs Extended Access Barring (EAB) when a Machine Type Communication (MTC) device performs an attempt to access an evolved Node B (eNB) in a wireless communication system are provided. When User Equipment (UE) supporting MTC, an MTC device, performs an attempt to access a network, the system and method determines whether it can access the network and performs the access procedure. The system and method can control the operations of UE that performs an attempt to access a network, thereby preventing excessive access.

7. A Machine Type Communication (MTC) device for controlling access to an evolved Node B (eNB) in a wire communication system, the MTC device comprising:
-
a transceiver for transmitting and receiving signals to and from the eNB; and a controller, wherein the controller; determines whether a Radio Resource Control (RRC) connection establishment corresponds to a Cause 1 or a Cause 2; controls to establish, if the RRC connection establishment corresponds to the Cause 1, the RRC connection so that the RRC connection is not subject to an Extended Access Baring (EAB) procedure; and determines, if the RRC connection establishment corresponds to the Cause 2, whether to employ the EAB procedure according to an establishment of a System Information Block (SIB) transmitted from the eNB, and employing the EAB procedure according to the determination. - View Dependent Claims (8, 9, 10, 11, 12)
