Design And Implementation Of Super Base Station Monitoring System

The super base station is a centralized access network device based on resource pooling,which can realize resource sharing and on-demand allocation.It not only improves the utilization of resources,but also can effectively solve the problem of large operation and maintenance expenses,large energy consumption and tidal effects caused by the large-scale deployment of traditional base stations.The super base station monitoring system is a solution for real-time monitoring of the super base station.The real-time monitoring of the super base station can not only timely detect and locate the problem of the super base station to improve the operation and maintenance efficiency,the service capability of the super base station,but also the monitoring data of the acquisition can be used to control the efficient and stable operation of the super base station.In this paper,through the in-depth analysis of the architecture and characteristics of the super base station,the super base station monitoring system is designed and implemented.The main contributions are as follows:1.The connectivity of the network between the super base station nodes is the basis of the resource pooling of the super base station,and the heartbeat mechanism is currently a widely used method for monitoring network connectivity.However,the existing heartbeat mechanism considers the network delay only for the factors that may cause misjudgment,cannot adapt to the scenario where the super base station node is restarted or powered off normally.In addition,the small heartbeat interval setting causes a large network traffic overhead.In this paper,by using the dichotomy method to obtain the optimal heartbeat interval,the network node instant working status flag is added to the heartbeat packet and combined with the designed heartbeat monitoring decision mechanism to optimize and improve the existing heartbeat mechanism.the test results show that the improved heartbeat mechanism can accurately determine the heartbeat loss caused by network delay,node restart or power-off,and reduce network overhead compared with the existing heartbeat mechanism.2.The processing of concurrent monitoring data is the core of the monitoring system.At present,for the super base station monitoring data concurrent processing,thread pool technology is mostly used.However,at least how many threads are needed to process the monitoring data of a certain amount of nodes under the processing time requirement is still inconclusive.For this issue,by testing the relationship between processing time and the number of nodes and the number of threads,the thread pool size calculation model under the processing time requirement of one second is obtained,and can support process monitoring data of 3000 nodes.Then,the thread pool control strategy is designed with this model,the test results show that the thread pool control strategy can effectively control the size of the thread pool.3.By analyzing the super base station layers of architecture,the functional requirements of the super base station monitoring system are divided into two parts: the node and the monitoring server.The node side mainly implements the collection of monitoring data,software monitoring,software and firmware update;the server mainly implements monitoring data collection and active/standby server switching.Finally,the monitoring system is tested and analyzed.The results of the test analysis show that the designed monitoring system can realize the monitoring of the super base station and the concurrent processing of the monitoring data.
