Application scenarios are also diversified, such as mobile broadband, large-scale internet, mission-critical internet, and the like. The requirements to be met are also diversified, such as mobility, safety, time-lapse, reliability, and the like. Just because different application scenarios have different requirements in the aspects of network function, system performance, security, user experience and the like, if the same network is used for providing services, the network is very complex and heavy, the requirement of the ultimate performance required by the application cannot be met, and meanwhile, the operation and maintenance of the network become quite complex, and the cost of network operation is increased. On the contrary, if a dedicated network is deployed to provide services according to different requirements of different service scenarios, and the network only includes functions required by the application scenario, the efficiency of the services is greatly improved, the network performance required by the application scenario can be guaranteed, the operation and maintenance of the network become simple, and the investment and operation and maintenance costs can be reduced. This is the network slicing technique, which is an example of a network slice.

In summary, slicing is the final characteristic of 5G, and how to automatically perform slice deployment and monitoring is the key technology of 5G slicing. Although the related protocol provides a development direction of the technology of network slicing, no specific scheme is provided for how to automatically deploy the network slicing.

Since 3GPP only defines the general architecture of the slice and only defines the radio network and the core network, and the 5G slice relates to three professional networks, the networking and resources are complex, and it is difficult to abstract the slice into one or several templates to directly match the user requirements, the whole networking situation needs to be found according to the user access area, and the design and deployment of the slice are performed on the basis. In contrast, the method and system provided by the present invention can find the networking resources of "base station-bearer-edge/core" according to the area where the slice user is located, and design the slice resources according to the SLA requirements of the user: and determining resources required by the slice in three subnets of wireless, load bearing and edge/core, and determining whether to reuse the original resources or newly-built resources. After the resources are confirmed, slice deployment and calling capacity, flow, monitoring and strategies are designed.

For a clearer explanation of the above end-to-end slice automation deployment method, the following description is made with reference to specific embodiments.

In an embodiment, in combination with step S101, a slicing user proposes a slicing service requirement, as shown in fig. 2, which is an interface schematic diagram of the slicing service requirement, where the slicing service requirement includes: slice type, SLA (Service Level Agreement), security isolation Level, and coverage area. In which, as seen by way of example with reference to figure 2,
