Patent number: 8315807Abstract: There is provided a molecular communication system capable of transmitting an information molecule in which predetermined information is encoded to a target destination under good controllability. The molecular communication system includes a molecular transmitter for transmitting the information molecule with prescribed information encoded, a molecular receiver for receiving the information molecule, and a molecule transmission channel extending between the molecular transmitter and the molecular receiver. The molecule transmission channel defines a transmission path formed of macromolecular (or polymer) materials, along which carrier molecules are circulating in a prescribed direction. The information molecule output from the molecular transmitter is loaded on the carrier molecule and carried to the molecular receiver.Type: GrantFiled: March 3, 2006Date of Patent: November 20, 2012Assignee: NTT DoCoMo, Inc.Inventors: Satoshi Hiyama, Yuki Moritani, Tatsuya Suda

Patent number: 7400601Abstract: It is an object of the present invention to provide a mobile communication system capable of shortening a delay time preceding the reception of a multicast packet at a radio base station which has been reached by a movement of a mobile terminal. The mobile communication system includes a multicast router, a data layer link switch, a radio base station, and a mobile terminal. In cases where the mobile terminal detects switching of the radio base station but does not detect switching of the multicast router, a path establishing request, a withdrawal request, and another path establishing request are sequentially output. When the switching of the radio base station and the switching of the multicast router is detected, a path establishing request is transmitted to the new multicast router, and a withdrawal request is transmitted to the previous multicast router thereafter.Type: GrantFiled: March 26, 2004Date of Patent: July 15, 2008Assignee: NTT DoCoMo, Inc.Inventors: Yuki Moritani, Yukio Atsumi
