Abstract:
(EN) Disclosed are a data stream transmission method and related devices. In embodiments of the present invention, when a media forwarding device monitors a data stream sent by a user terminal by means of a WIFI network, if it is determined that a data packet in the data stream needs to be retransmitted, the media forwarding device sends a retransmission notification message to the user terminal by means of an LTE network; the notification message carries the serial number of the data packet needing to be transmitted, so that the user terminal retransmits the data packet on the LTE network according to the retransmission notification message. The embodiments can achieve the technical effect of transmitting a data packet of a VoWIFI service by means of two networks, i.e., the LTE network and the WIFI network, so that the smoothness of the VoWIFI service is improved.
(FR) L'invention concerne un procédé de transmission de flux de données et des dispositifs associés. Dans des modes de réalisation de la présente invention, lorsqu'un dispositif de transfert multimédia surveille un flux de données envoyé par un terminal utilisateur au moyen d'un réseau Wi-Fi, s'il est déterminé qu'un paquet de données dans le flux de données doit être retransmis, le dispositif de transfert multimédia envoie un message de notification de retransmission au terminal utilisateur au moyen d'un réseau LTE ; le message de notification transporte le numéro de série du paquet de données devant être transmis, de sorte que le terminal utilisateur retransmet le paquet de données sur le réseau LTE conformément au message de notification de retransmission. Les modes de réalisation permettent de réaliser l'effet technique de la transmission d'un paquet de données d'un service VoWi-Fi au moyen de deux réseaux, c'est-à-dire le réseau LTE et le réseau Wi-Fi, de sorte que la régularité du service VoWi-Fi est améliorée.
(ZH) 本发明公开一种数据流传送方法和相关设备,其中,本发明实施例中的媒体转发设备在监控用户终端通过WIFI网络发送的数据流时,如果确定数据流中的数据包需要重传,则通过LTE网络向用户终端发送重传通知消息,该通知消息中携带需要重传的数据包的序号,以便于用户终端根据该重传通知消息在LTE网络上重传数据包,本实施例可以获得通过LTE网络和WIFI网络两个网络来传输VoWIFI业务的数据包的技术效果,提高了VoWIFI业务的流畅度。
