Abstract
The present invention is to accommodate a large number of users required in a digital radio communication system and to prevent communication quality from deteriorating. The present invention is to prevent the occurrence of a delay by adding a process for restricting packet assignment for a call having low communication quality. When the average DRC value is equal to or smaller than a threshold, assigned slots are thinned out to improve communication quality for radio terminals close to cell boundaries and to increase the number of radio terminals accommodated. As a method for thinning out assigned slots, packets received from an upper level unit of a radio base station are, for example, discarded before transmission as long as the lowest limit sound quality is maintained. With this operation, the lowest limit sound quality is ensured.
