摘要
现有3G/4G蜂窝组网系统对于数据链路的建立、配置和释放都采用握手交互机制,存在问题:1流程繁琐且伴随大量异常处理;2当链路管理同步失败后数据将无法恢复。针对此问题,提出一种基于数据驱动的无线链路管理策略,一旦数据传输模块通过数据感知到工作状态不同步的时候,会主动向主控模块发起查询进行同步,恢复正常的数据传输。最后通过数学分析模式,验证本策略在数据链路管理上的有效性和可靠性。
The existed 3G/4G cellular network system,the establishment,configuration and release of data link are based on handshake mechanism,there are following problems： 1 The process is tedious and accompanied by a large number of exception handling; 2 When the synchronization of data link failed,the process of data transmission will interrupt. To solve the problem,this paper proposes a wireless link management policy bases on data driven,once the data transmission module sensed the working state out of sync,it will take initiative to query the main control module to synchronize,recover the normal data transmission. At the end,we build mathematics analysis module to verify the effectiveness and reliability of our data link management policy.
