Patent number: 8780708Abstract: A control server 4, receives the number of user terminals U which have transited to the individual Web pages from a monitoring server 3 in Step S41. In Step S42, based on the received number of transitions U of the individual Web pages, application of control is decided by the control server 4. Here, based on the assumption that the number of transitions Uc to a Web page C including a transaction access or hyper link to the end server 2 accurately represents the number of executed transactions, the number of transitions Uc to Web page C is compared with an upper limit value Cmax. When Uc<Cmax, the process proceeds to Step S43 and a control information is sent from the control server 4 to the user terminals 1 to cancel the application of control.Type: GrantFiled: March 30, 2009Date of Patent: July 15, 2014Assignee: KDDI CorporationInventors: Hideyuki Koto, Yasuhiko Hiehata, Satoshi Uemura, Hajime Nakamura

Patent number: 8582435Abstract: A module transmits a request for line connection to a module at a communication time notified from a module. The module proceeds to line connection processing in response to the request for line connection and notifies the module of success or failure of line connection. The module notifies a log database of the notified success or failure of line connection. The log database records success or failure of line connection in a database as log data and notifies the module of the log data at predetermined time intervals. The module revises a communication time based on the log data and notifies the module of the revised communication time.Type: GrantFiled: March 16, 2011Date of Patent: November 12, 2013Assignee: KDDI CorporationInventors: Hajime Nakamura, Yasuhiko Hiehata, Hideyuki Koto

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
