Abstract
【解決手段】方法は、UE(ユーザー端末)が専用H−RNTI(HS−DSCH無線ネットワーク一時指示子)を含み、かつアップリンクデータ伝送の実行によりCELL_PCH(セルページングチャネル)状態からCELL_FACH(セルフォワードアクセスチャネル)状態に移行するときに、タイマーを停止する段階を含む。前記タイマーはUEがCELL_PCH状態に入るときに起動するタイマーで、第一DRXサイクルの使用時間を決めるために用いられる。

Description
ステップ302:UEが専用H−RNTIを含み、かつアップリンクデータ伝送の実行によりCELL_PCH状態からCELL_FACH状態に移行するときに、タイマーを停止する。前記タイマーはUEがCELL_PCH状態に入るときに起動するタイマーで、第一DRXサイクルの使用時間を決めるために用いられる。
ステップ304:終了。
まとめていえば、本発明の実施例では、UEがCELL_PCH状態から離れた後にUEのタイマー319を停止することで、システムエラーを防止してダウンリンクDRX機能を改善する。
