Abstract
Description
図1は、第1実施形態における通信システムを示す図である。図1に示すように、通信システムは、複数のUE(User Equipment)100と、E−UTRAN(Evolved−UMTS Terrestrial Radio Access Network)10と、EPC(Evolved Packet Core)20とを有する。
次に、第2実施形態における通信システムを説明する。第2実施形態におけるネットワーク構成や機能ブロックは、図1〜図7に示した第1実施形態におけるネットワーク構成や機能ブロック図と同じである。
次に、第3実施形態における通信システムを説明する。第3実施形態におけるネットワーク構成や機能ブロックは、図1〜図7に示した第1実施形態におけるネットワーク構成や機能ブロック図と同じである。また、第2実施形態では下りリンクデータの送達状況に基づく処理を対象としたのに対して、第3実施形態では上りリンクデータの送達状況に基づく処理を対象とする。
上述した第1実施形態では、PDCPパケットを例に挙げて説明したが、これに限られない。PDCPパケットの代わりに、GTP−Uパケットが用いられてもよい。すなわち、カプセル化エンティティ166及びカプセル化エンティティ244は、GTP−Uエンティティとしての機能を有していてもよい。
