Title (EN) WIRELESS TERMINAL AND WIRELESS TERMINAL HANDOVER METHOD
(FR) TERMINAL SANS FIL ET PROCÉDÉ DE TRANSFERT DU TERMINAL SANS FIL
(JA) 無線端末および無線端末のハンドオーバー方法
Abstract: front page image
(EN)A wireless terminal comprises a data transmitting/receiving function and a handover control part. The handover control part uses all of available wireless channels to scan the presence or absence of the existence of a handover destination. By scanning the presence or absence of the existence of the handover destination before executing the handover, the handover control part acquires candidates of the handover destination and executes a checking scan to check if any one of the candidates is located within a range communicatable from the terminal. The handover control part then executes the handover based on the result of executing the checking scan.
(FR)La présente invention concerne un terminal sans fil qui comprend une fonction de transmission/réception de données et une partie de commande de transfert. La partie de commande de transfert utilise tous les canaux sans fil disponibles pour scanner l'existence ou l'inexistence d'une destination de transfert. En scannant l'existence ou l'inexistence de la destination de transfert avant d'exécuter le transfert, la partie de commande de transfert obtient des candidats de la destination de transfert et exécute un balayage de vérification pour vérifier si un quelconque des candidats est situé à l'intérieur d'une plage communicable depuis le terminal. La partie de commande de transfert exécute ensuite le transfert en fonction du résultat de l'exécution du balayage de vérification.
(JA) データ送受信機能とハンドオーバー制御部とを備えた無線端末を構成する。ハンドオーバー制御部は、利用可能なすべての無線チャネルでハンドオーバー先の存在の有無をスキャンする。ハンドオーバー制御部は、ハンドオーバー実行前に事前にハンドオーバー先の存在の有無をスキャンすることにより、ハンドオーバー先の候補を取得し、その候補が、端末から通信可能範囲内にあるか調べるために検証スキャンを実行する。そして、検証スキャンの実行結果に基づいて、ハンドオーバーを行う。
