Patent number: 8542594Abstract: A throughput detector 101 detects a throughput R0. A threshold value Rref of the throughput R0 at which a network side can be presumed to be congested is stored in a threshold value storage unit 102. A comparator 103 compares the current throughput R0 with the threshold value Rref. A release request unit 104 requests release of a wireless resource when the throughput R0 falls below the threshold value Rref. In response to the release request, a controller 100 suitably disconnects a physical layer or a logical layer of a wireless section to release the wireless resource. A release term determining unit 105 determines a release term of the wireless resource. A resource request unit 106 makes the released wireless resource be acquired anew after the elapse of the release term to reconnect the wireless communication.Type: GrantFiled: June 28, 2011Date of Patent: September 24, 2013Assignee: KDDI CorporationInventors: Yasuhiko Hiehata, Hideyuki Koto, Hajime Nakamura

Patent number: 8509174Abstract: A communication permitted slot setting section 12a randomly and equally divides one prescribed cycle for each wireless terminal and sets some of them, respectively, as permitted slots “p.” A communication assigning section 12b assigns the total communication “n” per one cycle pre-assigned to each wireless terminal to each permitted slot “p.” A communication timing determining section 12c randomly determines communication timings for each permitted slot “p.” A degree-of-congestion measuring section 12d measures the degree of congestion of wireless resources. A connectivity estimating section 12e estimates the connectivity M for each permitted slot. Each time a communication opportunity is consumed, a communication readjusting section 12f assigns the communication opportunity to an permitted slot with a higher connectivity M at a higher probability in the next cycle.Type: GrantFiled: August 22, 2011Date of Patent: August 13, 2013Assignee: KDDI CorporationInventors: Hideyuki Koto, Hajime Nakamura, Yasuhiko Hiehata
