摘要
GSM-R网络的数据链路层信令可用于协助问题定位,对通信问题的诊断至关重要。但目前只能获得数字形式的信令,无法直接得到其内容,而人工解析过程极其复杂,导致时间和人力成本增加。针对该问题,基于3GPP和ETSI相关标准,提出一种数据链路层信令关键内容自动化解析算法,通过结合控制信道类型动态适配解析规则的方法,实现信令内容自动解析、误码检出和信息化展示。试验结果表明,该算法对京广高铁采集的信令数据解析准确率达100%,误码检测准确率为100%,可支撑6万条信令在21 min完成处理,较人工解析效率提升97%。相较于传统解析方法,该算法保证了信令解析的准确性,并显著提高了时效性。
Signaling at the GSM-R data link layer can be instrumental for problem localization and is crucial for diagnosing communication issues.However,currently,the signaling data is only accessible in a raw digital format,and its content cannot be directly interpreted.The manual parsing process is prohibitively complex,leading to significant increases in both time and labor costs.To address this issue,this paper proposes an automated parsing algorithm for key data link layer signaling content,based on 3GPP and ETSI standards.By dynamically adapting the parsing rules according to the control channel type,the algorithm enables automatic parsing of signaling content,bit error detection,and informational display.The test results show that the algorithm achieved 1oo%accuracy in parsing and bit error detection on signaling data collected from the Beijing-Guangzhou HSR.It efficiently processed 60 Oo0 signaling messages in 21 minutes,which translates to a 97%increase in efficiency compared to manual parsing.This algorithm is superior to conventional parsing approaches in both accuracy and timeliness.
