COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION CONTROL METHOD

摘要

An interface accesses a server for managing usage of a plurality of frequency resources allocated to a first wireless system and acquires information indicating the usage. Based on the acquired information, a control unit selects, amongst the frequency resources, a frequency resource to be used by a second wireless system. The control unit determines whether, after the information is acquired at a first time point, reacquisition of the information at a second time point is successful, which second time point is scheduled to reacquire the information from the server. If the reacquisition is unsuccessful, the control unit allows a frequency resource for the second wireless system to be selected based on the information acquired at the first time point even from the second time point onward.

主权项

1. A communication apparatus comprising:
an interface configured to access a server for managing usage of a plurality of frequency resources by a first wireless system, which frequency resources have been allocated to the first wireless system, and acquire usage information indicating the usage from the server; a storing unit configured to store the acquired usage information; and a control unit configured to select, based on the usage information, a frequency resource to be used by a second wireless system amongst the frequency resources, wherein the control unit determines whether, after the usage information is acquired at a first time point, reacquisition of the usage information at a second time point is successful, the second time point being scheduled to reacquire the usage information from the server, and when the reacquisition is unsuccessful, the control unit allows the selecting to be made based on the usage information acquired at the first time point and stored in the storing unit even from the second time point onward.
