The present invention is a resource request and a packet scheduling method and an apparatus for the uplink traffic of the mobile communication system relates . For efficient scheduling, the ; uplink traffic , the base station and the terminal is set to a predetermined scheduling scheme according to the characteristics of the traffic when negotiating . Traffic may be one of the traffic caused by the packet of the variable size traffic , and the random time interval for generating a packet of a variable size with traffic , a predetermined time interval to generate a packet of a fixed size at a predetermined time interval . ; Thus, the terminal in a manner that reflects the traffic characteristics requested resources, the base station also by performing a scheduling based on the traffic characteristics , is made the optimal UL scheduling .
