Abstract

La présente invention concerne un procédé et un appareil de commutation de port, et un procédé et un appareil d'indication de commutation de port. Le procédé de commutation de port consiste à : selon des informations d'indication envoyées par un dispositif de réseau, déterminer, parmi une pluralité de configurations de signal de référence de sondage (SRS), une configuration cible pour une commutation de port ; et effectuer une commutation de port selon la configuration cible. Selon la présente invention, un dispositif de réseau peut envoyer dynamiquement des informations d'indication à un terminal, et indiquer, parmi une pluralité de configurations de SRS, une configuration cible pour une commutation de port. En utilisant les informations d'indication, le dispositif de réseau peut indiquer dynamiquement la configuration de SRS pour une commutation de port au terminal, pour ainsi envoyer une configuration de SRS appropriée au terminal d'une manière relativement opportune, de façon à s'adapter à un port qui doit être utilisé par le terminal pour envoyer un SRS. Le terminal peut recevoir dynamiquement la configuration de SRS, et effectuer une commutation de port en utilisant la configuration de SRS reçue, de façon à commuter vers un port approprié pour envoyer le SRS.
