System and method for applying extended accessing barring in wireless communication system
First Claim
Patent Images
1. A method by a user equipment (UE) in a wireless communication system, the method comprising:
- requesting, by a first layer of the UE, a second layer of the UE to establish a radio resource control (RRC) connection; and
identifying, if the UE receives an extended access barring (EAB) parameter, whether an EAB is applied to a request for the RRC connection,transmitting a first random access preamble to a base station, if the EAB is not applied to the request for the RRC connection;
receiving a random access response including a first type backoff and a second type backoff; and
transmitting a second random access preamble based on one of the first type backoff and the second type backoff.

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.

-
a transceiver configured to transmit and receive signals; and a processor configured to; request, by a first layer of the UE, a second layer of the UE to establish a radio resource control (RRC) connection, identify, if the UE receives an extended access barring (EAB) parameter, whether an EAB is applied to a request for the RRC connection except, transmit a first random access preamble to a base station, if the EAB is not applied to the request for the RRC connection, receive a random access response including a first type backoff and a second type backoff, and transmit a second random access preamble based on one of the first type backoff and the second type backoff. - View Dependent Claims (7, 8, 9, 10)
