Abstract
The problem of multiple handover failures occurred several times during the testing and commissioning of Chizhou-Huangshan High-speed Railway are gradually investigated,and it is found that the fault occurred when the service cell initiated handover to the target cell(the cell with BSIC=50).This paper checks the CTCS-3 interface monitoring data of the trains with handover failure and signaling tracking data of the base station,and deeply analyzes the cell handover principle of the GSM-R system,to judge that the fault is determined to be a compatibility problem between the Triorail terminal and the base station,resulting in an abnormal BSIC decoding(in BSIC X0 configuration)and a handover failure.In view of this situation,after temporary measures are taken to either replace the Triorail terminal with the Funkwerk terminal or change the BSIC code,the test results show that the handover failure has not happened.However,it is still necessary to conduct in-depth cause analysis and disposal of abnormal BSIC decoding to avoid the recurrence of handover failure.关键词
