- the BSS / OSS 10 allocates the service to the existing slice. Therefore, the BSS / OSS 10 is used in comparison with the case where a new slice is generated each time a new service request is received. Services can be allocated to slices without wasting useable nodes and their resources.
- the assignment determination unit 13 satisfies the predetermined condition when the attribute of the existing slice satisfies the service requirement, and the comparison result between the cost when the service is assigned to the existing slice and the cost when the service is assigned to the new slice If so, assign the service to an existing slice.
