实时数据库在移动通信网中的并发控制研究

Research on Concurrency Control of Real-time Database System in Mobile Communication Network

针对传统的关系型数据库管理系统无法满足具有事务限时响应的实时性应用的问题 ,以及为了提供移动通信网本地位置寄存器HLR中的高可靠和高可用的访问服务 ,提出了一种实时数据库与商用数据库相结合的实现模式 ,用以提供大容量大事务处理能力和电信级高实时性响应的服务 ;分析了系统基于事务响应时间限制优先级要求的并发控制原理及利用主动触发机制解决数据竞争的实现方式 .

In order to provide a high reliable and practical data access, a mode which is the combination of real time database and commercial database is presented, and can provide large transaction service and high real time response. The concurrency control theory based on its transaction response time priority and the realization of initiative trigger is analyzed.
