摘　　要：介绍了移动分布式实时事务的工作模式,在此基础上提出了应用于移动分布式实时事务的实时原子交换协议:两层实时原子提交协议。通过引入改进的TCP三次握手协议,完成移动终端与固定数据库系统的交互。对协议的正确性进行了证明。两层实时原子提交协议能够有效避免由于网络故障或者移动终端故障引起的通信堵塞。Mobile distributed real-time transaction working mode is introduced, and based on which, the two-layer real-time atomic commit protocol applied to mobile distributed real-time transaction system is presented. Through the exercise of modified TCP three times shaking hand protocol, interactions between the mobile terminals and the fixed database systems are realized, and the legitimacy of the protocol is prooved. Two-layer real-time atomic commit protocol can effectively avoid the correspondence jams caused by network troubles or mobile terminal troubles.
