Abstract
【解決手段】第1の通信パラメータのセットを用いる第1のアクセスポイント(AP)から第2の通信パラメータのセットを用いる第2のアクセスポイント(AP)にワイヤレス送/受信ユニット(WTRU)が移動する方法。当該方法は、第2のアクセスポイントの識別子、第2の通信パラメータのセット及び第2のアクセスポイントへの移動が行われる時間を含む移動要求メッセージを、第1の通信パラメータのセットを用いる第1のアクセスポイントから受信するステップと、移動要求メッセージに基づいて第2のアクセスポイントへの移動をするかどうかを判定するステップと、第2のアクセスポイントへの移動をするという判定に応答して、第2の通信パラメータのセットを用いる第2のアクセスポイントと通信することを再設定するステップとを含む。
【選択図】図3
Description
1.元のAPがWTRUに要求して、目的のAPにハンドオフさせる。WTRUはその後ハンドオフするか否かを決定し、その決定を元のAPに伝える。WTRUがハンドオフを進めることを決定する場合、WTRUはそのチャネル、BSSID等を目的のAPに対して再構成し、目的のAPに再関連付け完了を示す確認メッセージを送信する。
2.元のAPがWTRUにコマンドして、目的のAPにハンドオフさせる。WTRUはその後、そのチャネル、BSSID等を目的のAPに対して再構成し、目的のAPに再関連付け完了を示す確認メッセージを送信する。
3.目的のAPがWTRUにコマンドして、目的のAPにハンドオフさせる。WTRUはその後、自身が通信中の元のAPに対し目前のハンドオフを通知し、そのチャネル、BSSID等を目的のAPに対して再構成し、目的のAPに再関連付け完了を示す確認メッセージを送信する。
4.目的のAPがWTRUに要求して、目的のAPにハンドオフさせる。WTRUはその後ハンドオフするか否かを決定し、その決定を目的のAPに伝える。WTRUがハンドオフを進めることを決定する場合、自身が通信中の元のAPに対し目前のハンドオフを通知し、そのチャネル、BSSID等を目的のAPに対して再構成し、目的のAPに再関連付け完了を示す確認メッセージを送信する。
1.送受信機とプロセッサとを備えるアクセスポイント(AP)。
Claims (3)
- 第1の通信パラメータのセットを用いる第1のアクセスポイント(AP)から第2の通信パラメータのセットを用いる第2のアクセスポイント(AP)にワイヤレス送/受信ユニット(WTRU)が移動する方法であって、
前記方法は、
第2のアクセスポイントの識別子、第2の通信パラメータのセット及び第2のアクセスポイントへの移動が行われる時間を含む移動要求メッセージを、第1の通信パラメータのセットを用いる第1のアクセスポイントから受信するステップと、
前記移動要求メッセージに基づいて前記第2のアクセスポイントへの移動をするかどうかを判定するステップと、
前記第2のアクセスポイントへの移動をするという判定に応答して、第2の通信パラメータのセットを用いる第2のアクセスポイントと通信することを再設定するステップと
を含むことを特徴とする方法。 - 前記第2のアクセスポイントへの移動に関する判定結果を示す移動応答メッセージを、第1の通信パラメータのセットを用いる第1のアクセスポイントに送信するステップをさらに含むことを特徴とする請求項1に記載の方法。
- 前記移動要求メッセージは、ワイヤレス送/受信ユニットが前記第1のアクセスポイントから直ちに接続解除されることを示すフラグを含むことを特徴とする請求項1に記載の方法。
