And the solutions of the three problems above are discussed:The solution to the simulcast interfering which is caused by the simulcast delay spread and the zero-beating is given in chapter four.Based on the well understanding of the principle of MS-I/H/0 in IPNP, the examples are given in chapter five on how to solve the problem of communication interruption between paging zones.Through the analyse of signal switching between Chengdu and Deyang, the synchronization error between FLEX frames, and the bug in the multi-frequency roaming principle are pointed out. And solutions are also recommended.

通过以上分析，文章探讨了对上述三个问题的解决：·对同播干扰问题，分别分析了时延差和零拍频所造成同播干扰的客观存在，探讨了系统设计和网络优化的基本方法；·对IPNP联网障碍，提出了在掌握IPNP对各PNCC作为输入局／归属局╱输出局的灵活定义、以及相关参数配置原理的基础上，分析联网障碍的思路；·对信号切换障碍，以成都和德阳两地的局部广域覆盖为例，分析了FLEX帧失步和FLEX多频漫游原理设计缺陷的客观存在，并探讨了相关的解决方法和建议。
