Title (EN) WIRELESS COMMUNICATION TERMINAL AND ROAMING METHOD FOR SAME
(FR) TERMINAL DE COMMUNICATIONS SANS FIL ET PROCÉDÉ D'ITINÉRANCE POUR CELUI-CI
(JA) 無線通信端末、及び無線通信端末のローミング方法
Abstract:
(EN) The present invention is provided with: a scanning unit that, when roaming in which connections to access points are switched while moving is performed, scans the access points in sequence beginning with scan regions having high priority rankings; and a roaming execution unit for making a connection, according to the results of the scan using the scanning unit, when an access point for the roaming destination exists. If the results of the scan performed in scan regions having a priority ranking of one indicate that no access point exists for the roaming destination, the scan unit performs a scan in scan regions having priority rankings lower than one.
(FR) La présente invention comporte: une unité de balayage qui, lors d'une itinérance pendant laquelle des connexions à des points d'accès sont changées en cours de déplacement, balaie successivement les points d'accès en commençant par des régions de balayage dotées de rangs de priorité élevés; et une unité d'exécution d'itinérance servant à établir une connexion, en fonction des résultats du balayage effectué par l'unité de balayage, lorsqu'il existe un point d'accès pour la destination d'itinérance. Si les résultats du balayage effectué dans les régions de balayage dotées d'un rang de priorité de un à indiquent qu'il n'existe aucun point d'accès pour la destination d'itinérance, l'unité de balayage effectue un balayage dans des régions de balayage dotées de rangs de priorité inférieurs à un.
(JA)  移動中にアクセスポイントの接続を切り替えるローミングを行う場合に、優先順位の高いスキャン帯域から順にアクセスポイントのスキャンを実行するスキャン部と、スキャン部によるスキャンの結果により、ローミング先のアクセスポイントがある場合に接続を行うローミング実行部と、を備え、一の優先順位のスキャン帯域でのスキャンによるスキャン結果で、ローミング先のアクセスポイントがない場合に、スキャン部は一の優先順位よりも低い優先順位のスキャン帯域でスキャンを行う。
