1. A method by a base station in a communication system, the method comprising:
- transmitting a paging message to a terminal, the paging message including information indicating a change of extended access barring (EAB) information;
transmitting first system information including scheduling information related to second system information having changed EAB information without waiting until a next system information modification period; and
transmitting the second system information including the changed EAB information based on the scheduling information,wherein the second system information includes category information indicating a category of terminals for which the changed EAB information is applied.

Abstract
A method for controlling delay tolerant access of a Machine-Type Communication (MTC) device based on a backoff mechanism is provided. The method includes receiving, at a terminal, a paging message including an access barring information update indicator from a base station, and receiving a System Information Block (SIB) including updated access barring information, the SIB being received regardless of modification periods. The terminal receives the SIB including the updated access barring information immediately without waiting for the arrival of next modification period, resulting in improvement of access barring efficiency.
