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 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 receiving, by the UE, an extended access barring (EAB) parameter,
- identifying whether an EAB access barring is applied to a request for the RRC connection, based on the received access barring parameter;
- and
- when the access barring is not applied to the 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 backoff information,
- determining a backoff value based on the backoff information and a scaling factor, and
- transmitting a second random access preamble based on one of the first type backoff and the second type backoff the backoff value.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a transceiver configured to transmit and receive signals;
- and
- a at least one processorconfigured to:;
- a memory storing instructions, wherein the instructions, when executed by the at least one processor, cause the at least one processor to control to:
- request, by a first layer of the UE, identify a request for a second layer of the UE to establish a radio resource control (RRC) connection,
- identify, if in case that the UE receives an extended access barring (EAB) parameter, whether an EAB access barring is applied to a request for the RRC connectionexcept, and
- in case that the access barring is not applied to the request for the RRC connection:
- 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 backoff information, and
- determine a backoff value based on the backoff information and a scaling factor, and
- transmit a second random access preamble based on one of the first type backoff and the second type backoff the backoff value.
