摘要
从LTE终端小区选择的高层协议入手,从适合小区和可接受小区驻留条件出发,分析了小区选择正常过程,并对条件不满足的后续小区选择深入研究,设计了解决方案,给出了相应的设计流程,并利用SDL(规范说明与描述语言)和TTCN(树表结合表示法)协议仿真,产生MSC(消息顺序图)。仿真结果表明,该方案有效地完成了协议所要求的小区选择功能。
According to LTE high layer protocol of terminal cell selection and a suitable and acceptable cell condition, the normal process of cell selection is analyzed with focus on the subsequent cell selection process when the above condition is not satisfied. The corresponding design flow is given. And the MSC (Message Sequence Charts) is produced using SDL (Specification and Description Language) and TI'CN (Tree and Tabular Com- bined Notation) co - simulation. The simulation result shows that the design can effectively complete the required cell options by specification.
