Description
Digital Network)等のような他のネットワークへのアクセスのような、様々なサービスを提供する。
Terrestrial Radio Access)、および、E−UTRAN(Evolved Universal Terrestrial Radio Access Network)に関する、複数の技術仕様書、例えば、3GPP TS 36.300が存在する。LTEの規格化作業の目的は、高速データレート、低遅延、およびパケットに最適化された無線アクセス技術に対する、3GPP無線アクセス技術の進化のためのフレームワークを開発することである。特に、LTEは、パケット交換(PS:Packet switched)ドメインから提供されるサービスをサポートすることを目指す。3GPP LTE技術の主たる目標は、約100Mbps以上の高速パケット通信を可能にすることである。
