Abstract

La présente invention concerne un dispositif et un procédé de détection d'un effet ping-pong. Le procédé consiste : lorsqu'un terminal accède à une cellule de desserte, à obtenir un ID de cellule de desserte actuelle, un temps d'accès, un temps de commutation de cellule de desserte et une durée de desserte au niveau d'une cellule de desserte actuelle ; à extraire, de liaisons respectives commutées vers une cellule de desserte, une liaison de sous-commutateur de cellule de desserte accédant de manière répétée à la cellule de desserte ; à calculer, conformément à des durées de desserte de diverses cellules de desserte, une durée de desserte moyenne des diverses cellules de desserte dans la liaison de sous-commutateur de cellule de desserte ; lorsque la durée de desserte moyenne est inférieure à une durée de desserte pré-configurée, à déterminer qu'un effet ping-pong est présent au niveau de la liaison de sous-commutateur de cellule de desserte, de façon à régler un paramètre utilisé entre des cellules de desserte adjacentes dans la liaison de sous-commutateur de cellule de desserte.
