| 摘 要： | 在对蜂窝网络中切换算法研究的基础上,提出了TD-SCDMA系统中基于预留信道的自适应门限优先排队算法,并进行了系统仿真。仿真结果表明,该算法实现了VIP和快速移动用户的优先接入,在系统切换呼叫到达率较高时,能有效地降低用户接力切换呼叫的掉线率,高效地利用信道资源,提高了系统的QoS。本文提出的算法与优先级算法相比,切换失败率降低了50%。尤其是在高速移动台环境下,这种改进更加明显。

| Abstract: | After the investigation of the existing Baton Handover(BH) algorithms in cellular networks,a new BH algorithm in the Time Division Synchronous Code Division Multiple Access(TD-SCDMA) system is developed,which is called resource reservation based preferential queuing scheme with self-adaptive threshold.Simulation results show that this algorithm improves the PRI of VIP and high rate users.When the call rate of handover is higher,the division of users can improve the QoS of the system and the efficiency of th... |
