Communication control device, communication control method and recording medium

A communication control device comprising:

• a transmission unit transmitting, to each of a plurality of communication devices performing communication by use of a previously allocated communication resource, an allocation information indicating allocation of a communication resource used by each of the plurality of communication devices when performing communication;
• an intermediate state generation unit generating, when changing allocation of the communication resource to each of the plurality of communication devices from a first allocation state to a second allocation state, an intermediate state indicating allocation of the communication resource, based on the first allocation state and the second allocation state, and
• a communication monitoring unit configured to monitor a first communication performed by a first communication device of the plurality of communication devices,
• wherein the transmission unit transmits the allocation information to each of the plurality of communication devices in such a way that the first allocation state changes to the second allocation state via the intermediate state generated by the intermediate state generation unit, so that each resource assignment of the intermediate state is greater than or equal to a lower limit of the communication resource,
• wherein the intermediate state is a first intermediate state, and the first intermediate state changes a resource assignment of the first communication device,
• wherein the intermediate state generation unit generates a second intermediate state, based on a monitoring result by the communication monitoring unit, and
• wherein the monitoring result indicates whether a monitored transmission of the first communication device matches the first intermediate state.
