The invention discloses a radio resources scheduling method for dynamically scheduling the radio resources of streaming media services in a multi-carrier radio communication system including multiple sub-carriers, the method comprising steps of: obtaining from a physical layer the information of the quality of radio channel on each sub-carrier for each user. The method further comprises: obtaining from a cache layer the play time information which indicates how long the data remained in the cache of receiving terminal of each user will be played continuously; and selecting in turn the users and sub-carriers corresponding to the maximums of an evaluating function based on the evaluating function obtained by a linear combination of the information of the quality of radio channel and the reciprocal of the play time information of the residual data and allocating the users to the corresponding sub-carriers.
