行動通訊發展至今已是人類生活中不可或缺的一環,在發展先進的國家,行動通訊更是司空見慣、習以為常,然而在第三世界因為經濟落後無法購買昂貴的通訊設備,無法享有行動通訊所帶來的便利,還有嚴重的天然災發生後,基地台坍塌、故障,使得通訊中斷[7],災民受困於災區,而無法利用行動裝置向外界求救,以上的狀況都是迫切需要通訊,但現在仍然沒有解決的問題,主要的原因在於基地台太昂貴,且難以隨身攜帶。
OpenBTS[2]是GNU Radio[1]所發展軟體定義無線電(Software Define Radio, SDR)相較於傳統通訊系統的硬體成本低、重量輕的優點,但是通訊範圍受限於一個OpenBTS,且使用OpenBTS需要具備的無線通訊和計算機的知識背景,一般人無法容易的使用軟體定義無線電。
為了解決OpenBTS不容易被使用的問題,本論文提出基於OpenBTS之自我組織網路,讓OpenBTS擁有自我配置和自我修復的能力,使用者啟動OpenBTS後即刻自動運行,提供OpenBTS間的通訊;在未來第三世界使用本系統,輕易地架設OpenBTS,提供行動通訊;重大災害導致無法通訊的情況下,救難人員可攜帶重量輕的OpenBTS前進災區,建立救難人員與災民間的通訊。


Mobile communication is something indispensable to human life. It is a common need in developed countries. However, in other hand, third world countries are also in urgent need of communication system, but the price of base station equipment is very expensive. Serious natural disasters collapse the base station and communication system. Trapped victims need help in the disaster area. The mentioned above problems need urgent and special communication system. Most of these problems, which related to expensive equipment price and difficult to carry, were not solved properly.
OpenBTS is SDR(Software Define Radio) developed by the GNU[1]. It has low cost and easy carry than traditional hardware. However, the implementation of SDR communication system needs communication knowledge and computer science background, so most people difficult to use it.
In order to solve the problem for OpenBTS mentioned above, then this paper proposes “An OpenBTS Base Self-organizing Emergency Communication System”. This scheme will provide self-configuration, self-optimization, and self-healing ability. User can simply turn the OpenBTS on, then it will automatically operated, and provide inter-cell communication. In the future, OpenBTS system using this scheme will easy to be implemented, provide portability, and establish communication in the disaster area.
