Research on leveled hybrid multi-service based on delay scheduling algorithm

Following the topic discussion for QoS,the forward wireless packet scheduling in the 1x EV-DO system is analyzed and di-scussed.It focuses on the service which has delay QoS(interacting and streaming class).An urgency/non-urgency determinant rule is introduced to transfer the pre-scheduled packets which have different degree of urgency to urgent or non-urgent queue according to the different delay demand for each packet,and a leveled hybrid multi-service scheme is proposed.It is proven that the sche-duling could guarantee the delay of service more effectively than EXP by simulation using Matlab software.
