Abstract:
1. A method of scheduling data packets in a data packet scheduling apparatus containing a scheduler in a communication system, comprising: determining by the scheduler a number of real-time data packets to be transmitted with priority according to an allowed transmission delay time from among a total of real-time data packets; scheduling by the scheduler the determined number of the real-time data packets and non-real time data packets so as to transmit the determined number of the real-time data packets and then transmit the non-real time data packets; and scheduling remaining real-time data packets other than the determined number of the real-time data packets after the scheduling of the non-real time data packets, so as to transmit the remaining real-time data packets after the non-real time data packets, wherein, when a data packet scheduling period is a frame, the number determination comprises determining a number of the real-time data packets to be transmitted with priority among the real-time data packets according, to the allowed transmission delay time, a frame length, and an allocation ratio being a weight for real-time data packet transmission.
