Patent number: 9461772Abstract: A packet interval (a time difference between sequentially received packets) in a certain previous time is calculated and a cumulative distribution function of the calculated packet interval is obtained. Meanwhile, a function value-corresponding to-flow end that is a boundary value of the cumulative distribution function to be considered as a flow end (timeout) in the range of a cumulative distribution function value is stored. From the cumulative distribution function obtained as described above, a value of a packet interval mapped to a cumulative distribution function value that matches the function value-corresponding to-flow end is set as a threshold. That is, the threshold is dynamically set based on a previous packet interval. Therefore, a packet stop period from a last packet reception time to a current time is measured, and it is detected as a flow timeout at a timing when the measured value is equal to or greater than the threshold.Type: GrantFiled: July 24, 2012Date of Patent: October 4, 2016Assignee: NEC Communication Systems, Ltd.Inventors: Hiroyuki Iizuka, Toshiyasu Tanaka, Koichi Yoshimura, Masahito Iwai, Tetsuya Ito

Patent number: 9374784Abstract: A terminal device 2 transmits a wireless frame having a frame length or amplitude that represents the ID of a wireless base station 1 to be woken up to the wireless base station 1. The wireless base station 1 detects the wakeup ID from the frame length or amplitude of the wireless frame from the terminal device 2, and, if the detected wakeup ID is identical with its own ID, transitions from a sleep mode to an operating mode. In this case, the wireless frame is the same wireless frame as that transmitted and received by the wireless communication module of the terminal device 2 to and from the wireless base station 1.Type: GrantFiled: February 16, 2012Date of Patent: June 21, 2016Assignees: ADVANCED TELECOMMUNICATIONS RESEARCH INSTITUTE INTERNATIONAL, NEC COMMUNICATION SYSTEMS, LTD.Inventors: Yoshihisa Kondo, Hiroyuki Yomo, Suhua Tang, Sadao Obana, Tetsuya Ito, Koichi Yoshimura, Masahito Iwai, Toshiyasu Tanaka, Hiroyuki Iizuka
