| Abstract: | To cope with the situation that multiple networks coexist in the metro wireless private network, and a single network cannot be comprehensively carried, this paper analyzed the communication requirements of the metro application system and the current situation of the comprehensive carrying of the metro private network, put forward the comprehensive carrying scheme of the 5G New Radio (5G NR) metro private network, and focused on the service adaptation and network isolation scheme based on 5G NR network slice. For meeting the complex application requirements and security isolation requirements of metro, the paper proposed an extended method of 5G NR network slicing, that was, two-layer network slicing method. |
