Railway communication bearer network slice division method and system oriented to comprehensive bearer

The invention belongs to the technical field of bearer network slice division, and particularly relates to a comprehensive bearer-oriented railway communication bearer network slice division method and system. The dividing method comprises the following steps: determining a service scene and dividing slices according to the service scene; distinguishing services of the slices and dividing sub-slices according to the services; and carrying out service level agreement index distribution on the sub-slices. According to the method, the comprehensive bearing of the service can be realized, the unified model can be divided and managed by combining the slicing technology and the SLA characteristics of the service, the later implementation and maintenance are facilitated, the comprehensive bearing is realized, the isolation is carried out at the same time, and the flexibility and customization capability of the network are improved at the same time of ensuring the service reliability. 本发明属于承载网切片划分技术领域，特别涉及一种面向综合承载的铁路
