Abstract

Contraposing the poor coverage of 4 G, the mobile jitters, large network delay and the characteristics of LTE system resource scheduling in the subway station, this paper proposes an improved resource scheduling algorithm – improved algorithm of PF utility function based on distance game (hereinafter referred to as M-DG PF/UF algorithm). Then construct optimization model of M-DG PF/UF algorithm, take the distance game on the concurrency user which requests the communication, and take priority scheduling, using the priority as the base parameter, to carry the relevant scheduling out on the subway dynamic resources. Finally, made analysis for the performance of PF, EXP/PF, M-LWDF and M-DG PF/UF algorithm, the simulation results show that the improved algorithm is better than the traditional resource scheduling algorithm, makes the limited system resources of TD-LTE cover more effective users and achieves the optimization goals of subway station radio resource scheduling.
