Description
他の実施の形態及び利点が以下の詳細な説明に述べられる。この概要は、本発明を定めるものではない。本発明は、請求項によって定められる。
図1は、一新規態様による無線通信システム100とUE101のブロック図120を示す図である。図1は、ある本発明の態様をサポートするUE101のブロック図120である。アンテナ134は、RF信号を送受信する。アンテナ134に結合されるトランシーバモジュール133は、アンテナ134からRF信号を受信し、それらをベースバンド信号に転換し、プロセッサ132に伝送する。トランシーバ133は、プロセッサ132から、受信したベースバンド信号も受信し、それらをRF信号に転換し、アンテナ134に伝送する。プロセッサ132は受信したベースバンド信号を処理し、異なる機能モジュールを起動して、UE101中の特徴を実行する。メモリ131は、プログラム命令とデータを保存し、UE101の操作を制御する。
図1に示されるように、LTEシステム100は、複数のeNB102、103、104、105および106を含む。UE101はeNB102と接続され、設定情報をUE101に伝送して、UE101から、問題イベント報告を受信する。ネットワーク110と通信中のeNBは、UE問題イベント報告を、ネットワーク110に伝送または転送することができる。本発明の一態様において、関連時間情報は問題イベント報告に用いられる。この方法は図1に示される。問題イベントに関連する相対時間を使用し、これにより、UE101に、正確な参照時間を知ることを要求しない。代わりに、ネットワーク構成要素、たとえば、eNB102またはネットワーク110は、UE101により設定される関連時間情報および一般に知られているリファレンスイベントに基づいて、問題イベントの絶対時間Bを推定することができる。
時間情報と問題イベントまたはMDT報告の効果的な関連付けは、ネットワーク最適化を改善する重要な態様である。MDTが3GPP規格で発展して、サービスエリアおよび別のネットワーク計画情報を入手するのを助ける時、どのようにして、MDTのバッテリー状態を効果的に処理するかが重要になっている。MDTは高いエネルギー消耗なので、MDTのバッテリーハンドリングの改善が必要とされる。
