Abstract: Provided are a communication control method, a communication control device, and a communication system that can appropriately change a device on a network that executes request processing from a terminal. In a node changing device 10, a sequence monitoring unit 12 detects handover of a UE 90. When the handover is detected, a placement calculation unit 14 acquires node information in the vicinity of a destination and activates nodes in the vicinity based on the node information. In this manner, upon detecting movement of a communication terminal, the node changing device 10 activates nodes in the vicinity of the destination of the communication terminal, and it is thereby possible to prevent an increase in communication delay even when the communication terminal is moved.

Abstract: A slice allocating method capable of dynamically changing a service and a slice to be allocated to the service is provided. An OSS/BSS holds allocation service information in which a service to which a slice has been allocated is associated with the slice. Further, a request reception unit of the OSS/BSS receives an SLA-SL which is a requirement of a function. An allocation determination unit determines a slice having an SLA-SL corresponding to a service requirement of the received service. When the service of the slice determined by the allocation determination unit is the same as the service associated with the slice in advance, an allocation request unit reallocates the service to the determined slice.

Abstract: A service allocation determination device and service allocation determination method that can allocate a service to a slice without wasteful use of resources. In a BSS/OSS, a service request receiving unit receives service requirements and information indicating functions for implementing a service. An allocation determination unit, using the service requirements and slice information, determines whether to allocate the service to an existing slice or to a new slice. An allocation request unit makes a request to allocate the service to the slice determined by the allocation determination unit. In this case, because the BSS/OSS 10 determines whether to allocate the service to an existing slice or to a new slice based on the service requirements and the attribute of the existing slice, the service can be allocated to a slice without wasteful use of resources.

A storing unit of a NFVO stores slice utilization status information. In a BSS/OSS, an allocation determination unit determines to create a new slice or extend an existing slice, and when resources for creation of a new slice or extension of an existing slice are insufficient, a resource change determination unit determines a slice for reduction based on the slice utilization status information. A resource request unit of the NFVO reduces resources of the determined slice.
