Communication management device, communication management method, and storage medium for communication management

A communication management method performed by a processor for managing communication between a vehicle and an outside of the vehicle, the communication management method comprising:

• acquiring a requested bandwidth, which is a communication bandwidth requested for execution of a specific process in the vehicle, and includes a desired bandwidth and a required bandwidth that are different level bandwidths;
• identifying a frequency band to which the requested bandwidth is allocated, in accordance with a communication capacity of the vehicle;
• and
• transmitting, to the vehicle, an allocation result of allocating the requested bandwidth with respect to the identified frequency band, wherein the allocation result includes whether at least one of the desired bandwidth or/and the required bandwidth is available;
• wherein:
• the vehicle is one of a plurality of vehicles, which includes a first vehicle having a first supported frequency band, and a second vehicle having a second supported frequency band that is narrower than the first supported frequency band;
• and
• the method further comprises identifying a frequency band that is outside the second supported frequency band and within the first supported frequency band, as the frequency band to be allocated to the first vehicle.

A non-transitory, tangible storage medium storing a communication control program including instructions configured to, when executed by a processor, cause the processor to:

• acquire a requested bandwidth, which is a communication bandwidth requested for execution of a specific process, and includes a desired bandwidth and a required bandwidth that are different level bandwidths;
• identify a frequency band to which the requested bandwidth is allocated, according to a communication capacity of a device with the specific process;
• and
• transmit to a vehicle, an allocation result of allocating the requested bandwidth with respect to the identified frequency band, wherein the allocation result includes whether at least one of the desired bandwidth or/and the required bandwidth is available;
• wherein:
• the vehicle is one of a plurality of vehicles, which includes a first vehicle having a first supported frequency band, and a second vehicle having a second supported frequency band that is narrower than the first supported frequency band;
• and
• the instructions are further configured to, when executed by the processor, cause the processor to identify a frequency band that is outside the second supported frequency band and within the first supported frequency band, as the frequency band to be allocated to the first vehicle.
