Title:
DATA TRANSMISSION METHOD, TERMINAL AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/063465
Kind Code:
A1
Abstract:
Provided by the embodiments of the present application are a data transmission method, a terminal and a storage medium, the method comprising: a first terminal acquires the identifier of a quality of service (QoS) flow of the first terminal and a QoS parameter of the QoS flow which have a corresponding relationship and determines a logical channel used by the QoS flow on a PC5 interface according to the QoS parameter; and the first terminal maps the QoS flow to the determined logical channel, and sends the QoS flow to a second terminal. Since QoS mechanisms on a Uu interface and the PC5 interface are unified QoS mechanisms, when any one of the Uu interface and the PC5 interface cannot continue to transmit data, the first terminal may switch the QoS flow to the other interface for transmission, so as to flexibly switch data transmission between different interfaces, and ensure no packet loss during interface switching.
