摘要
目前地铁建设出现了采用多个LTE-M系统综合承载以及实际运营使用基站共享(Radio Access Network Sharing,RAN Sharing)的最新复杂组网形式,急需理论验证。从可靠性理论入手,建立可靠性框图数学模型,将设备硬故障与无线通信传输软故障合理地进行系统综合,建立了多LTE-M系统应用RAN Sharing技术组网时系统可用性解析表达,验证了RAN Sharing组网方案的可行性,支撑了国内同类型重大工程建设。
At present,LTE-M system has been widely used in subway construction,and the latest complex networking forms of RAN Sharing(Radio Access Network Sharing) has been used in actual operation,which need theoretical verification urgently.Starting from the reliability theory,this paper establishes the mathematical model by reliability block diagram,reasonably integrates the hardware fault of equipment with the soft fault of wireless communication transmission,establishes the analytic expression of system availability when multi lte-m system is networking by using RAN Sharing technology,verifies the feasibility of Ran sharing networking scheme,and supports the construction of the same type of major projects in China.
