摘要
移动通信设备对无线通信系统的要求是简化切换过程,缩短切换时间,减少切换次数,提高切换成功率。针对这些要求,给出了全球移动通信系统(GSM)路径损耗模型,并分析了信道切换对GSM通信网络的影响。提出了基于规则确定越区切换小区,相邻小区列表的简化和目标小区信道提前激活的混合优化算法。通过数据仿真实验,可以看出越区切换的时间延时得到有效降低,缩短了切换时间,证明了所提算法的有效性。
Simplifying the handoff process, shortening the handoff time, reducing the handoff times, and improving the handoff success rate are the requirement of mobile communication device to wireless communication system. In this paper, the GSM path loss model was given and analysis the influence of channel handoff on GSM communication network. The hybrid optimization algorithm was given, which composed of based the rules determine handoff district, simplified adjacent district list and ahead activate target district channel. Through data simulation experiments, the handoff time delays has been effectively reduced and shorten the handoff time which proved the effectiveness of the proposed algorithm.
