Abstract

Abstract: In view of the hybrid system of eHRPD in 3G and TD-LTE in 4G, the cell will overload with the increase of users. The vertical handover between the different standards can be applied besides the traditional handover of the neighboring cells. This paper studies the load balancing in the hybrid network of eHRPD and TD-LTE. The proposed algorithm refers to the network resource utilization when the users are handed off. Therefore, the load in the hybrid network can be balanced. Through the simulation of the integrated system, our scheme can enhance the average throughput while the radio link failure is unaffected. Moreover, the best handover thresholds can be obtained with the largest throughput.

Key words: load balancing, handover, overlapping, throughput, scheduling
