Abstract

Un procédé de rapport d'informations de positionnement et un appareil de communication sont divulgués. Le procédé comprend les étapes suivantes : un dispositif de réseau reçoit un premier message envoyé par un terminal et envoie un deuxième message à un dispositif de gestion de positionnement, à la fois le premier message et le deuxième message comprenant des premières informations de positionnement, et les premières informations de positionnement comprenant un premier résultat de mesure obtenu par le terminal mesurant un premier signal de référence, le premier message étant transporté dans une signalisation RRC, et le deuxième message étant transporté dans la signalisation NRPPa. Étant que les premières informations de positionnement échangées entre le terminal et le dispositif de gestion de positionnement sont transportées par la signalisation RRC et la signalisation NRPPa successivement, et étant donné qu'une période de rapport autorisée par la signalisation RRC est inférieure à une période de rapport autorisée par la signalisation LPP, et la signalisation NRPPa ne restreint pas une période de rapport, par conséquent, la période pour rapporter les informations de positionnement du terminal peut être raccourcie, et la plage d'application est plus large.
