Design of LTE-M Interface Monitoring System of Signal and Signaling Interface

The design of a Long Term Evolution for Metro (LTE-M) monitoring system of the CBTC signal and signaling interface is introduced in this paper. The network structure of the LTE-M system was introduced, and the necessity of monitoring the CBTC interface and LTE-M signaling interface was analyzed. The monitoring function of the signal interface was given, and the protocol stacks of the S1, S5, S10, and S6a interfaces were described. Then, the entire structure and implementation methods were described in detail. Finally, the interfaces of the monitoring system were shown. The accomplishment and application of the LTE-M monitoring system will aid in building and maintaining the LTE-M system.
