- LTE Linkを備え、VoLTE、PSVT、Normal PSサービスを、小型セルに接続された端末に提供するFAPデバイスの駆動方法において、
LTE FAPのサービスが開始する段階(S1000);に続き、
LTE FAPのコントローラが新規端末の接続ないし他のFAPからのHand inによる端末の変動があるか否かをモニタする段階(S1100)を実行し、変動がない場合には引き続きモニタする段階(S1100);
前記端末の変動があるか否かをモニタする段階(S1100)で変動があった場合、新規端末に対するVoLTE、PSVT、Normal PSのサービス種類を抽出して区分する段階(S1200);を実行し、
次に、前記コントローラは、抽出されたサービス種類をセル内に提供する場合にシステムの負荷量を計算する段階(S1300);を実行し、
前記段階(S1300)で計算されたシステムの負荷量と全体システムの負荷量とを比較して全体システムの負荷量を超えるか否かを判断する段階(S1400);を実行し、
前記段階(S1400)で計算されたシステムの負荷量が全体システムの負荷量を超えないと判断された場合、前記コントローラはLTE FAPに新規端末を接続してサービスを提供(S2000);し、端末の変動があるか否かをモニタする段階(S1100);を実行し、
前記段階(S1400)で計算されたシステムの負荷量が全体システムの負荷量を超えると判断された場合、前記コントローラは前記新規接続する端末のサービスタイプよりも低い優先順位のサービスを受けている端末を検索し(S1600)、前記低い優先順位のサービスを受けている端末がある場合、前記低い優先順位のサービスを遮断し(S1700)、前記低い優先順位のサービスを受けている端末がない場合、前記新規接続する端末の接続を遮断する(S1700)段階を繰り返すものの、
システム負荷率が減少する方向に対してはいつもサービス切替を許容し、
VoLTE、PSVTサービスからNormal PSに切り替える場合、音声あるいは映像呼終了時点にRRC connection releaseを実行した後、Normal PS開始時点に再びLTE FAPに接続されるようにし、
VoLTEからPSVTに切り替える場合、サービス種類の切替時の予想負荷を計算し、予想負荷が最大負荷よりも大きい場合、Normal PS端末を1つリリースした後に切り替えを許容し、Normal PS端末がない場合には切り替えを許可せず、端末がリリースするように駆動されることを特徴とする小型セルの流動的接続制御FAPデバイスの駆動方法。 - 前記サービスの前記優先順位は、VoLTE、PSVT、Normal PSの順序であることを特徴とする請求項1に記載の小型セルの流動的接続制御FAPデバイスの駆動方法。
- 現在接続された端末がNormal PSのサービス提供を受けている場合、
E−RAB SetupメッセージとしてQCI1が伝送されると、現在接続された端末をVoLTEに切り替え、
E−RAB SetupメッセージとしてQCI1とQCI2が伝送されると、PSVTサービスに切り替え、
現在接続された端末がPSVTサービスの提供を受けている場合、
E−RAB ReleaseメッセージとしてQCI2が伝送されると、現在接続された端末をVoLTEに切り替え、
E−RAB ReleaseメッセージとしてQCI1とQCI2が伝送されるとNormal PSサービスに切り替え、
現在接続された端末がVoLTEサービスの提供を受けている場合、
E−RAB SetupメッセージとしてQCI2が伝送されると、現在接続された端末をPSVTに切り替え、
E−RAB ReleaseメッセージとしてQCI1が伝送されると、Normal PSサービスに切り替えるように構成されたことを特徴とする、請求項1または2に記載の小型セルの流動的接続制御FAPデバイスの駆動方法。 - 前記FAPデバイスの駆動方法は、
FAPデバイスのセルでサービス中の周波数帯域に対して他の帯域としてLTEのサービスが供給された場合、該当LTEのサービス中の周波数にリリースする端末をリダイレクションし、
FAPデバイスのセルでサービス中の周波数帯域に対して他の帯域として、RAT(Radio Access Technology)サービスが供給される場合には、該当RATのサービス中の周波数にリダイレクションし、
このときのリダイレクション処理は、端末リリース時に端末に伝送されるRRC connection releaseメッセージにRedirected Carrier Infoフィールドを追加して達成されるように構成されたことを特徴とする請求項3に記載の小型セルの流動的接続制御FAPデバイスの駆動方法。
