  • Mobile communication system, location registration method, relay node and control method thereof, and storage medium of control program
    Patent number: 8983463
    Abstract: A communication processing system includes a user equipment, a base station and a relay node for relaying the user equipment and the base station. The relay node includes a timer unit which measures a prescribed time after detecting movement between tracking areas and a user equipment registration unit which registers the user equipment, which is a transmission source of a location registration request signal to a location information management unit, which manages location information, received by the relay node during the prescribed period, as a subordinate of the relay node.
    Type: Grant
    Filed: June 4, 2012
    Date of Patent: March 17, 2015
    Assignee: NEC Corporation
    Inventors: Yozo Yoshimura, Sadafuku Hayashi

  • Network administration system and method of re-arranging network resources
    Patent number: 6941347
    Abstract: A network administration system includes a network administrator which performs re-arrangement of network resources. The network administrator includes functions of estimating a probability at which failures would occur in a cell in which network resources have been re-arranged, and repeating rearrangement of network resources for minimizing the probability, calculating a probability at which failures would occur, based on data about past cells, and indicating a probability at which failures would occur in each of cells in which network resources have been re-arranged.
