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 without waiting until a next system information modification period; and
transmitting second system information including the changed EAB information to the terminal, if the first system information includes scheduling information related to the second system information,wherein the second system information includes first information indicating a category of terminals for which the changed access barring information is applied, andwherein the category comprises one of a first category indicating all terminals, a second category indicating terminals with the exception of terminals served by a home public land mobile network (HPLMN) and an equivalent PLMN, and a third category indicating terminals with exception of the terminals served by the HPLMN and the equivalent PLMN, and terminals related to roaming.

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.

6. A base station in a communication system, the base station comprising:
-
a transceiver configured to transmit and receive a signal; and a controller configured to; transmit a paging message to a terminal, the paging message including information indicating a change of extended access barring (EAB) information, transmit first system information without waiting until a next system information modification period, and transmit second system information including the changed EAB information to the terminal, if the first system information includes scheduling information related to the second system information, wherein the second system information includes first information indicating a category of terminals for which the changed access barring information is applied, and wherein the category comprises one of a first category indicating all terminals, a second category indicating terminals with the exception of terminals served by a home public land mobile network (HPLMN) and an equivalent PLMN, and a third category indicating terminals with exception of the terminals served by the HPLMN and the equivalent PLMN, and terminals related to roaming. - View Dependent Claims (7, 8, 9, 10)
