Fig. 3 shows the schematic block diagram of the method 100 for being used for transmission data of the embodiment of the present application.As shown in figure 3, this method 100 includes following part or all of content:

S110, terminal device is successfully received at least one downlink data packet for belonging to first service quality data stream of network equipment transmission being carried in the first Data Radio Bearer DRB, and each downlink data packet at least one downlink data packet carries the mark QFI for identifying the first service quality data stream.

S 120, the terminal device indicate that the network equipment stops subsequent carrying the QFI in the downlink data packet for belonging to the first service quality data stream according at least one downlink data packet.

Specifically, above-mentioned mark (the QoS flow ID for referring to the network equipment and carrying affiliated quality of service data stream in each downlink data packet, QFI), in the embodiment of the present application, the network equipment carries the QFI of the QoS flow until terminal device sends instruction information to the network equipment in the downlink data packet for belonging to same QoS flow, and the network equipment just stops at and carries QFI in downlink data packet.Terminal device can be successfully received one or more downlink data packet and then send information to the network equipment.

Therefore, the method for being used for transmission data of the embodiment of the present application, by carrying QFI in the rear downlink data packet for stopping at the subsequent same QoS flow to network equipment instruction for being successfully received the downlink data packet for belonging to the same QoS flow, network overhead is advantageously reduced.

Optionally, in the embodiment of the present application, which is a downlink data packet.Specifically, terminal device just can indicate stop carrying QFI in the subsequent downlink data packet for belonging to the QoS flow in first downlink data packet for being successfully received some QoS flow that the network equipment issues to the network equipment.

Optionally, in the embodiment of the present application, which is multiple downlink data packets. Specifically, terminal device can before being successfully received some QoS flow that the network equipment issues several downlink data packets, just indicate can to stop in the subsequent downlink data packet for belonging to the QoS flow to the network equipment to carry QFI.Terminal device is indicated after several downlink data packets to the network equipment before being successfully received on earth, can be decided in its sole discretion by terminal device.
