首先介绍了Mobitex无线网络所采用的技术、遵循的协议及其与Internet接入的研究意义,目的在于使Mobitex在Intemet的接入中实现高速、可靠的通信,分析比较了采用TCP协议与UDP协议各自的优缺点,设计并实现了一个基于可靠用户数据报协议(RUDP)技术的数据传输机制,RUDP的设计基于UDP的通信机制,特点是数据的通讯不需要建立像TCP协议那样的三次握手的机制,而是通过同步交互消息完成了这个过程,避免占用较多资源,同时又使用了重传机制,克服了UDP协议的不可靠、数据无序到达的缺点.最后,实验结果表明了该设计的有效性.

At first,Mobitex wireless network is introduced,including its related technology and protocols.To achieve high speed and robust transmission between Mobitex and Intemet,after analysis and comparison the advantages and disadvantages of using TCP with those of using UDP,a data transfer mechanism based on RUDP (reliable user datagram protocol) technology is designed and implemented.The benefit is that the establishment of data communication relies on synchronous interaction messages,rather than three times handshake like TCP protocol,thus it avoids resource waste.At the same time,it uses retransmission mechanism and overcomes the weakness of data unreliability and disorder with UDP.The effectiveness of the design is verified by the experimental results at last.
