A method for broadcasting system information to a terminal performing machine-type-communication 'MTC', the method comprising: repeatedly transmitting, by a base station, a plurality of system-information blocks 'SIBs' and content associated with each of the plurality of SIBs with a periodicity capable of accumulatively detecting the plurality of SIBs and the content associated with each of the plurality of SIBs by the terminal using a resource allocation of a plurality of physical resource blocks 'PRBs' and a downlink channel associated with the base station in a radio access system ; accumulatively detecting, by the terminal , the plurality of SIBs and the content associated with each of the plurality of SIBs ; storing, by the terminal , the content associated with each of the plurality of SIBs as stored content; detecting, by the terminal , from the downlink channel in the radio access system , a transmission including a plurality of change flags associated with the plurality of SIBs , each of the plurality of change flags associated with one of the plurality of SIBs ; in response to detecting a change flag of the plurality of change flags having a first change flag value, reusing, by the terminal , the content of the SIB associated with the change flag, the first change flag value representing an absence of a change to the content of the SIB associated with the change flag; in response to detecting the change flag having a second change flag value, detecting, by the terminal , the SIB associated with the change flag and storing the content of the SIB associated with the change flag, the second change flag value representing a change to the content of the SIB associated with the change flag; and selectively detecting, by the terminal , SIBs having changed content based on the change flag values of the plurality of change flags. repeatedly transmitting, by a base station, a plurality of system-information blocks 'SIBs' and content associated with each of the plurality of SIBs with a periodicity capable of accumulatively detecting the plurality of SIBs and the content associated with each of the plurality of SIBs by the terminal using a resource allocation of a plurality of physical resource blocks 'PRBs' and a downlink channel associated with the base station in a radio access system ; accumulatively detecting, by the terminal , the plurality of SIBs and the content associated with each of the plurality of SIBs ; storing, by the terminal , the content associated with each of the plurality of SIBs as stored content; detecting, by the terminal , from the downlink channel in the radio access system , a transmission including a plurality of change flags associated with the plurality of SIBs , each of the plurality of change flags associated with one of the plurality of SIBs ; in response to detecting a change flag of the plurality of change flags having a first change flag value, reusing, by the terminal , the content of the SIB associated with the change flag, the first change flag value representing an absence of a change to the content of the SIB associated with the change flag; in response to detecting the change flag having a second change flag value, detecting, by the terminal , the SIB associated with the change flag and storing the content of the SIB associated with the change flag, the second change flag value representing a change to the content of the SIB associated with the change flag; and selectively detecting, by the terminal , SIBs having changed content based on the change flag values of the plurality of change flags. <EOS>
