摘　　要：为了提高LTE实时业务调度的公平性,首先在M-LWDF资源调度算法的优先级判断机制中引入了平均传输速率和保证比特速率,然后将经济学中的效用思想和效用函数引入到M-LWDF调度算法中,提出了一种基于时延效用函数和速率效用函数的M-LWDF改进算法,以便更好地体现调度算法的时延特性和速率特性。In order to enhance the scheduling fairness of LTE real time service, the average transmission rate and grant bit rate are introduced to priority class iudgment mechanism of M-LWDF resource scheduling algorithm firstly. Then, the utility thought and utility function in economics is introduced to M-LWDF scheduling algorithm and an improved algorithm based on delay and rate utility function is proposed for reflecting the delay and rate character of scheduling algorithm better.
