Description

Local service guarantee method, device, base station and medium based on base station offload

technical field

The invention belongs to the technical field of communication, and in particular relates to a local service guarantee method, device, base station and storage medium based on base station offloading.

Background technique

Vertical industries have strong demands for 5G private networks, and the reliability and security requirements for private networks are higher than those of public networks. At this stage, data localization and unloading of vertical industries such as factories can be realized through base station shunting, ensuring that the data in the physical space out of the factory. After the wireless transformation of the factory's manufacturing production line is completed, if the entire production line is paralyzed due to transmission or core network failures, resulting in huge losses to the factory, a core network can be deployed locally as a backup. After the network service is interrupted, the local terminal reconnects to the local core network and continues to work normally to ensure the development of production services.

The existing solution of locally deploying a set of core networks as a backup requires re-laying a transmission network from the base station to the local core network. The local core network performs hot backup to keep the data of the public network core network and the local core network synchronized. Faults will lead to interruption of local services. If industry terminal equipment is reconnected to the local core network and restarts services, the original services may be interrupted and the production line business will be lost.
