Abstract:
1. A radio base station comprising: a call process controller configured to accept a normal call to call a communication destination and a priority call to be handled in preference to the normal call; and a baseband processor configured to allocate a baseband resource to the normal call or the priority call based on the normal call or the priority call accepted by the call process controller, the baseband resource being a traffic processing capability in a baseband, wherein the call process controller updates a status of the baseband resource based on a status of the baseband resource reported from the baseband processor and determines whether or not to accept a call based on the status of the updated baseband resource, the call process controller notifies the baseband processor of an offset of the baseband resource when accepting the priority call, and the baseband processor changes the baseband resource to be allocated to the normal call in a predetermined cycle, such that the normal call remains active while the baseband processor changes the baseband resource, and applies a resource use restriction based on the offset notified from the call process controller, the resource use restriction restricting the baseband resource to be allocated to the normal call within a range defined by subtracting the offset from a total baseband resource.
