A method, comprising: receiving an enhanced access barring, EAB, configuration from a mobility management entity, MME by a base station in a 3GPP LTE-Advanced mobile communication network, wherein the EAB configuration indicates a percentage of Machine-Type Communications, MTC, traffic to be barred and an EAB category to be barred; determining EAB information by the base station for a plurality of MTC devices, based on the EAB configuration, wherein the EAB information indicates which EAB categories to be barred and which access classes of a number of access classes to be barred, referred to as first access classes, and wherein the percentage of MTC traffic to be barred is matched by the base station to the number of access classes to be barred; broadcasting the EAB information by the base station to the plurality of MTC devices via a system information block, SIB; and transmitting by the base station an indication that the EAB information is being broadcasted to the plurality of MTC devices, indicating that the updated EAB information in the SIB can be read upon receiving the indication; the method further comprising: determining updated EAB information by the base station for a plurality of MTC devices, wherein the updated EAB information indicates which EAB categories to be barred and which second access classes of the same number but different from the first access classes to be barred; broadcasting the updated EAB information by the base station to the plurality of MTC devices via a system information block, SIB; and transmitting by the base station a further indication that updated EAB information is being broadcasted to the plurality of MTC devices, indicating that the updated EAB information in the SIB can be read upon receiving the indication. receiving an enhanced access barring, EAB, configuration from a mobility management entity, MME by a base station in a 3GPP LTE-Advanced mobile communication network, wherein the EAB configuration indicates a percentage of Machine-Type Communications, MTC, traffic to be barred and an EAB category to be barred; determining EAB information by the base station for a plurality of MTC devices, based on the EAB configuration, wherein the EAB information indicates which EAB categories to be barred and which access classes of a number of access classes to be barred, referred to as first access classes, and wherein the percentage of MTC traffic to be barred is matched by the base station to the number of access classes to be barred; broadcasting the EAB information by the base station to the plurality of MTC devices via a system information block, SIB; and transmitting by the base station an indication that the EAB information is being broadcasted to the plurality of MTC devices, indicating that the updated EAB information in the SIB can be read upon receiving the indication; the method further comprising: determining updated EAB information by the base station for a plurality of MTC devices, wherein the updated EAB information indicates which EAB categories to be barred and which second access classes of the same number but different from the first access classes to be barred; broadcasting the updated EAB information by the base station to the plurality of MTC devices via a system information block, SIB; and transmitting by the base station a further indication that updated EAB information is being broadcasted to the plurality of MTC devices, indicating that the updated EAB information in the SIB can be read upon receiving the indication. determining updated EAB information by the base station for a plurality of MTC devices, wherein the updated EAB information indicates which EAB categories to be barred and which second access classes of the same number but different from the first access classes to be barred; broadcasting the updated EAB information by the base station to the plurality of MTC devices via a system information block, SIB; and transmitting by the base station a further indication that updated EAB information is being broadcasted to the plurality of MTC devices, indicating that the updated EAB information in the SIB can be read upon receiving the indication.
