Abstract
【解決手段】LTEシステム80は、UE81、ソースeNB82、ネットワーク制御エンティティ83およびGPS装置84を含む。工程801において、UE81は、ソースeNB82により、局部的MBMSサービスを受信する。工程802において、eNB82は、ネットワーク制御エンティティ83から、MBMSサービス位置情報を獲得する。工程803において、eNB82は位置情報をUE81に送る。位置情報が幾何学的描写を含む場合、工程804において、UE81はその現在の位置(たとえば、GPS84から)を得る。工程805において、UE81が、相関区/領域内にある場合、現在の位置とサービスの位置情報に基づいて、UE81は、サービスの受信を開始または継続する。そうでなければ、UE81が相関区/領域(relevant region/aria)にない場合、UE81はサービス受信を停止する。
