Description
2. SRB1:専用制御チャネル(DCCH)を通して上位層NAS(ノンアクセスストラタム)の制御メッセージとRRCメッセージを交換・伝送する。アップリンク・ダウンリンクともRLC層のアクノレッジモード(AM)を利用する。
3. SRB2:DCCHを通して上位層NASの制御メッセージを交換・伝送する。アップリンク・ダウンリンクともRLC層のAMモードを利用する。
前記2種類のRRC接続プロセスでは、UEのRRC層は接続リクエストメッセージ(または接続再確立メッセージ)を生成し、更に下位層(MAC(媒体アクセス制御)層)でランダムアクセスプロセスを起動し、CCCHを通して接続リクエストメッセージ(または接続再確立メッセージ)をネットワークに送信する。同時に、UEはセルの無線信号を継続的に測定し、測定結果がセル再選択の基準に達した場合にセル再選択(cell reselection)を行い、より良い無線信号を提供できるセルと接続を確立する。前記RRC接続プロセスの動作について詳しくは仕様を参照すればよく、ここで説明を省略する。
ステップ402:RRC接続プロセスを実行する。
ステップ404:セル再選択の発生時にSRBに対応する下位層プロトコルエンティティーをリセットか再確立する。
ステップ406:終了。
