Description
"Frequency dispersion after MBMS reception" NTT DoCoMo R2-041616 3GPP TSG-RAN WG2 meeting #43 16-20.08.2004 Prague, Czech Republic, ppl-2には、MBMSサービスの受信が終了した後に周波数層にとどまるUEに起因するトラフィックの輻輳を低減するための複数のオプションが記載されている。これらのオプションはそのUEの先行の層を再選択すること、層をランダムに再選択すること、UTRANによってセットされたパーセンテージ割り当てに関連して層を再選択することである。
図1は本発明による方法が実施されるシステムのブロック図を示し、
図2は本発明の方法に含まれるステップのフローチャートを示す。
Claims (3)
- 単一周波数層での移動端末のためのセル再選択方法において、
前記周波数層におけるマルチキャストブロードキャスト・マルチメディアサービス(MBMS)セッションの終了を検出し、先行して使用された周波数に関して記憶されている情報の使用可能性を検査し、使用可能である場合には記憶されている情報の妥当性を検査し、妥当性を検査するステップは記憶されている情報がリストにおける周波数に関するかを検査し、使用可能でない場合または妥当でないことが検出された場合には周波数をリストから選択し、適切なセルを前記周波数において選択し、セル選択が失敗した場合には、移動端末が移動すべきセルはどのセルであるかを検出するために移動端末が初期セル選択プロシージャを実行することを特徴とする、単一周波数層での移動端末のためのセル再選択方法。 - 初期セル選択プロシージャは3GPP TS 25.304に従う、請求項1記載の方法。
- リストはシステム情報ブロック11/12リストである、請求項1または2記載の方法。
