PHD SCHEDULING SYSTEM AND METHOD FOR PHD NETWORK

摘要

The present invention relates to a scheduling system and method for a PHD network, and more particularly, to classifying messages measured in each PHD into a real-time transmission message or a delay-allowed message, and transmitting the classified message to the network manager 200 When the message received from the message classification module 100 is a real-time transmission message, the message classification module 100 transmits the message in real time, and if the message received from the message classification module 100 is a delay permission message The network manager 200 for transmitting the message to the scheduling module 300 and the transmission time of the delay grant message transmitted from the network manager 200, And a scheduling module (300) for delivering the message to the manager (200) The scheduler module 200 transmits a delay grant message to the scheduling module 300 at a transmission time determined by the scheduling module 300.According to the scheduling system and method for the PHD network proposed in the present invention, priority is given to messages measured in the PHD according to characteristics of messages, and a message measured in the PHD is transmitted in real time In the case of a delay permission message in which the measured message does not require an urgent transmission, a delay time is determined by determining the transmission time to avoid the time at which the real time transmission message is transmitted, The bottleneck phenomenon can be prevented from occurring.In addition, the present invention determines whether or not a delay grant message has been transmitted at the determined transmission time and reflects the result in the scheduling for determining the next transmission time so that the delay grant message can avoid the time at which the real-As shown in FIG.;
