随着通信事业的发展，各大单位的无线通信专网日益完善，系统要求也越来越高，各项性能更接近实际应用，操作也更简便。而目前上海消防部队使用的无线通信，是在一九九六年，根据公安部，国家无委重新划定的警用频率，设备主要采用ＭＯＴＯＲＯＬＡ公司ＧＭ３００和ＧＰ３００，用常规组网方式运行。由于时间仓促，只是根据以往的模式，着重于提高系统稳定性，没有对新系统的各项功能加以综合开发利用，加上总体频点的缺乏和实际使用中分配的不合理，使无线网络时常产生阻塞的现象，消防通信的局限性日益显现。因此，如何在频点短缺的情况下，合理分配资源，满足“平”战结合的需要和实现无线通信的及时性，就成为当前重组数字无线通信网络的实际需求……
With the development of communication, the wireless communication private network of major units is increasingly perfect, the system requirements are getting higher and higher, the performance is closer to the practical application and the operation is more convenient. At present, the wireless communications used by the Shanghai Fire Brigade are based on the police frequency of the Ministry of Public Security and the State that have not been redefined in 1996. The equipment mainly uses GM300 and GP300 from MOTOROLA Company and operates in a conventional networking mode. Due to time constraints, only based on the previous model, focusing on improving the stability of the system, without comprehensive development and utilization of the various functions of the new system, coupled with the lack of overall frequency and the actual use of the distribution of unreasonable, so that wireless networks often Blocking phenomenon, the limitations of fire communications increasingly apparent. Therefore, how to rationally allocate resources, meet the needs of “flat” warfare and ensure the timeliness of wireless communications under the circumstance of shortage of frequency points has become the actual demand of the current reorganization of digital wireless communication networks.
