Abstract:
1. A base transceiver station comprising: a radio quality calculating section that obtains radio quality between a radio access network and a mobile terminal apparatus; a channel quality calculating section that obtains channel quality between the base transceiver station and a radio network controller; a CPU utilization measuring section that measures CPU utilization of the base transceiver station; a memory that stores a table including a plurality of CPU utilization thresholds and a data rate reduction amount corresponding to each of the plurality of CPU utilization thresholds; and a permissible data amount calculating section that calculates permissible data amount based on the radio quality, the channel quality, the CPU utilization, and the data rate reduction amounts corresponding to the CPU utilization thresholds stored in the memory, wherein the base transceiver station is a small-size base transceiver station where the number of carriers is 1 or less, and is limited in a number of maximum concurrent connections.
