中文摘要
通訊科技的發達使得現今人與人之間的通訊有愈來愈多的選擇,目前市面上最常見的除了電信電話外即為日趨普及的通訊軟體、IP電話等等網路電話,然而不論是經由PSTN(Public Switched Telephone Network, 公共交換電話網)電話線路通訊的一般電話,或是藉由網路封包傳遞的VoIP(Voice over IP, 網際協議通話技術)網路電話,都仰賴著實體線路以及網路的穩定性,當電話線路故障、基地台故障,甚至是無法使用網際網路服務時,我們所習慣的通訊模式全部都無法運作。
有鑑於此,我們提出一套基於小型細胞基地台運作的通訊系統,我們設計一套通訊軟體,配合將EPC(Evolved Packet Core Networks)軟體化安裝的All-in-one模式小型細胞基地台,以及透過安裝在小型細胞基地台內與使用者裝置端的MQTT(Message Queuing Telemetry Transport)系統,讓使用者在無論是否能使用網際網路服務的情況下都能進行通訊。最後會對本論文提出的系統架構以及軟體進行實作與驗證,證明所提出的系統以及軟體在有無網際網路服務下的情況皆能進行通訊。
Abstract
Because of the great advancement of communication technologies, people have more choices to contact with each other. The common communication modes nowadays include telecommunications service, IP telephone, and communication apps. However, most of the communication systems are based on PSTN(Public Switched Telephone Network) that means the stability depending on the whole network. Even though VoIP(Voice over IP) is a packet-switching technology, its stability also depends on the Internet. However, in case the telephone system has broken down, or the Internet is unavailable, none of the above common communications could work.
To solve the problem, we proposed an independent communication system based on a proprietary small cell that has been installed light EPC(Evolved Packet Core Networks) software and MQTT(Message Queuing Telemetry Transport) system. Then we design a communication app which can contact with small cell via MQTT. By using proprietary small cell and developing the app, we can set up an independent communication system which can work with or without Internet.
