Abstract

Selon des modes de réalisation, la présente invention concerne un procédé et un dispositif de positionnement d'équipement utilisateur (UE), de mesure et de traitement. Le procédé comprend les opérations suivantes: une seconde station de base reçoit une requête de commutation envoyée par une première station de base, la requête de commutation comprenant un identificateur d'association de mesure E-CID et un identificateur d'UE; après réception d'un message d'achèvement de commutation d'un UE, la seconde station de base envoie un message de requête de commutation de chemin à une MME, le message de requête de commutation de chemin comprenant l'identificateur d'UE et une instruction servant à déclencher immédiatement une requête de positionnement, et l'instruction servant à déclencher immédiatement une requête de positionnement étant utilisée pour donner à la MME l'instruction d'envoyer immédiatement un second message de requête de positionnement à un E-SMLC; et la seconde station de base reçoit une seconde requête de démarrage de mesure E-CID envoyée par l'E-SMLC et effectue une mesure E-CID sur l'UE sur la base de la seconde requête de démarrage de mesure E-CID. Un délai de positionnement E-CID causé par re-déclenchement d'une mesure de positionnement durant un processus de commutation d'UE est donc réduit.
