  • Publication number: 20040203416
    Abstract: A mobile wireless communications system includes mobile terminals and a base station for wireless communications. A base station sends a pilot signal to the mobile terminals. The pilot signal received by the mobile terminal is correlated to a data rate according to predetermined rules. The correlated data rate is further correlated to a display symbol. The mobile terminal specifies the data rate correlated to the pilot signal received and causes a display device of the mobile terminal to display the display symbol correlated to the specified data rate for its user to view.

  • Patent number: 6718396
    Abstract: In the Internet having a plurality of autonomous systems interconnected, fast routing can be made. The autonomous systems constituting the Internet or the like are divided into groups. The border routers of one group share routing information of the group, and the border routers of another group share routing information of the group. Each border router has a unit for separating a desired one from the autonomous systems of a corresponding group or consolidating an autonomous system of another group into the corresponding group, so that the amount of the routing information held can be adapted to the processing ability of the border routers within that group.
