Abstract
(EN)
A wireless communication system wherein a radio terminal (200A) and a relay node (300A) are connected to a radio base station (100A), and at least one of the radio terminal (200A) and relay node (300A) can move. The radio base station (100A) controls a handover that is an operation of the radio terminal (200A) to change the connection destination thereof. The radio base station (100A) controls the handover from the radio base station (100A) to the relay node (300A) on the basis of whether a predetermined condition, which indicates that the change in relative distance between the radio terminal (200A) and the relay node (300A) is kept null or small, is satisfied or not.
(FR)
L'invention concerne un système de communication sans fil. Dans ce système, un terminal radio (200A) et un noeud relais (300A) sont connectés à une station radio de base (100A), et au moins l'un du terminal radio (200A) et du noeud relais (300A) peut se déplacer. La station radio de base (100A) commande un transfert intercellulaire qui est une opération du terminal radio (200A) pour modifier sa destination de connexion. La station radio de base (100A) commande le transfert intercellulaire de la station radio de base (100A) vers le noeud relais (300A) selon qu'une condition prédéterminée, qui indique que la modification d'une distance relative entre le terminal radio (200A) et le noeud relais (300A) reste nulle ou faible, est satisfaite ou non.
(JA)
 本発明の無線通信システムは、無線基地局100Aに無線端末200A及びリレーノード300Aが接続しており、無線端末200A及びリレーノード300Aの少なくとも一方が移動可能である。無線基地局100Aは、無線端末200Aが接続先を切り替える動作であるハンドオーバを制御する。無線基地局100Aは、無線端末200Aとリレーノード300Aとの間の相対距離の変化が無い又は小さい状態が維持されることを示す所定の条件が満たされたか否かに基づいて、無線基地局100Aからリレーノード300Aへのハンドオーバを制御する。
