摘要

针对LTE-Advanced中继系统提出了一种基于资源共享的呼叫接纳控制方法。如果目标站点内新用户和切换用户共享资源已经被使用完，切换用户可以使用目标站点为切换用户预留的资源接入系统，而新用户则可以通过目标站点所在小区内的站点间资源共享接入系统。仿真结果表明，与LTE-Advanced系统固定带宽预留方案和LTE-Advanced中继系统固定带宽预留方案相比较，提出的算法能有效降低小区内新用户阻塞率和切换用户的掉话率，并且能够提高系统的资源利用率。

Abstract

A call admission control based on resource sharing in LTE-Advanced relay system was proposed.If the shared resources of the target site for new users and handover users are used up，handover users can use the reserved r esources of the target site for handover users to access system，while new users can access system by resource sharing between the sites in the cell which the target site inside.Simulation results show that compared the proposed algorithm with LTE-Advanced system on fixed bandwidth reservation scheme and LTE-Advanced relay system on fixed bandwidth reservation scheme，the proposed algorithm can effectively reduce the blocking probability of new users and dropping probability of handover users in the cell，and can improve the system resource utilization.
