US 2006/0142017 A1 · Mobile terminal and wireless communication system

Abstract

A wireless communication system for high-speed motion use, capable of shortening the frequency channel search time and increasing the communication time available for service. The system includes an access point communicating on a designated one frequency channel and a mobile terminal communicating on the same received channel by receiving radio waves transmitted by the same access point. As for mobile terminal, in a storage, priority data is stored for a channel search in which arbitrary priorities can be set respectively for the channels. Frequency channel search sequence data, set up so that the number of times of appearance becomes greater for channels for which the priority data are set higher, are generated on the basis of the relative data, and a search of communication-capable channels is carried out in accordance with the same channel search sequence data.

Dependent claims

A mobile terminal for a wireless communication system including an access point communicating on a designated one of a plurality of frequency channels, wherein the mobile terminal communicates with said access point on the same received frequency channel by receiving radio waves transmitted by said access point and comprises storage means storing relative priority data for a frequency channel search which is set respectively for said plurality of frequency channels;

wherein the mobile terminal generates, on the basis of the relative priority data stored in said storage means, frequency channel search sequence data set up so that the number of times of appearance becomes greater for frequency channels for which the relative priority data are set higher;
and
wherein the mobile terminal carries out a search of the frequency channels with which communication is possible, following the frequency channel order of the same generated frequency channel search sequence data.
