Abstract

The present invention discloses a data stream transmission method and related equipment. According to the embodiments of the present invention, when a media forwarding device monitors that a user terminal sends data streams through a WIFI network, if it is determined that data packets in the data streams need to be retransmitted, the media forwarding device sends a retransmission notification message to the user terminal through an LTE network, wherein the notification message carries the sequence numbers of the data packets to be retransmitted, so that the user terminal retransmits the data packets on the LTE network according to the retransmission notification message. With the data stream transmission method and related equipment provided by the embodiments of the invention adopted, data packets of VoWIFI service can be transmitted through the LTE network and the WIFI network, and the smoothness of the VoWIFI service can be improved.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, and in particular to a data stream transmission method, device and system. Background technique [0002] With the development of network technology, voice over WIFI (Voice over WIFI, VoWIFI) services have begun to be provided for commercial use by operators. VoWIFI mainly carries real-time communication between users, such as voice calls and video calls, to a wireless fidelity (Wireless Fidelity, WIFI) network. [0003] During the VoWIFI service, the user's terminal, such as a mobile phone, accesses the core network of the operator's network through the WIFI network. The user's voice or video data stream is transmitted to the gateway in the operator's network through the WIFI network, and then forwarded by the gateway to the core network, and the core network sends the user's voice or video data stream to the peer user. [0004] In the VoWIFI service provided by the prior art, due ...
