Abstract:
1. A radio base station, comprising: a radio resource allocation determination processor configured for determining whether or not to allocate a radio resource to a first mobile communication device; a radio resource control processor configured for allocating the radio resource to the first mobile communication device to which the radio resource allocation determination processor has determined to carry out the allocation of the radio resource; and a backhaul line control processor configured for providing control of outputting data received from the first mobile communication device to a backhaul line for relaying the data to a higher-level network, wherein, when congestion occurs on the backhaul line: the radio resource control processor allocates an amount of the radio resource to be allocated to the first mobile communication device lower than an amount of the radio resource allocated before the occurrence of the congestion, while maintaining a connection between the first mobile communication device and the radio base station; and the radio resource allocation determination processor determines whether or not to allocate the radio resource to a second mobile communication device, which is different from the first mobile communication device and to which the radio resource is to be newly allocated after the occurrence of the congestion on the backhaul line, depending on whether or not the data received from the first mobile communication device satisfies a predetermined service quality.
