A method for broadcasting system information to a terminal (104a, 104b, 104c) performing machine-type-communication 'MTC', the method comprising: repeatedly transmitting, by a base station, a plurality of system-information blocks 'SIBs' (403, 404, 405) and content associated with each of the plurality of SIBs (403, 404, 405) with a periodicity capable of accumulatively detecting the plurality of SIBs (403, 404, 405) and the content associated with each of the plurality of SIBs (403, 404, 405) by the terminal (104a, 104b, 104c) 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 (104a, 104b, 104c), the plurality of SIBs (403, 404, 405) and the content associated with each of the plurality of SIBs (403, 404, 405); storing, by the terminal (104a, 104b, 104c), the content associated with each of the plurality of SIBs (403, 404, 405) as stored content; detecting, by the terminal (104a, 104b, 104c), from the downlink channel in the radio access system, a transmission including a plurality of change flags associated with the plurality of SIBs (403, 404, 405), each of the plurality of change flags associated with one of the plurality of SIBs (403, 404, 405); in response to detecting a change flag of the plurality of change flags having a first change flag value, reusing, by the terminal (104a, 104b, 104c), 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 (104a, 104b, 104c), 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 (104a, 104b, 104c), 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' (403, 404, 405) and content associated with each of the plurality of SIBs (403, 404, 405) with a periodicity capable of accumulatively detecting the plurality of SIBs (403, 404, 405) and the content associated with each of the plurality of SIBs (403, 404, 405) by the terminal (104a, 104b, 104c) 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 (104a, 104b, 104c), the plurality of SIBs (403, 404, 405) and the content associated with each of the plurality of SIBs (403, 404, 405); storing, by the terminal (104a, 104b, 104c), the content associated with each of the plurality of SIBs (403, 404, 405) as stored content; detecting, by the terminal (104a, 104b, 104c), from the downlink channel in the radio access system, a transmission including a plurality of change flags associated with the plurality of SIBs (403, 404, 405), each of the plurality of change flags associated with one of the plurality of SIBs (403, 404, 405); in response to detecting a change flag of the plurality of change flags having a first change flag value, reusing, by the terminal (104a, 104b, 104c), 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 (104a, 104b, 104c), 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 (104a, 104b, 104c), SIBs having changed content based on the change flag values of the plurality of change flags.
