example 1

[0049] In Example 1, the sending end device is a UE, which corresponds to signaling (reflective QoS) that may not carry a flow channel identifier and no reflective QoS information at the PDAP layer. The network side configures that one DRB (such as DRB_1) of the UE corresponds to only one flow ID (such as flow_1), and the network side indicates or agrees that one DRB corresponds to one flow ID, and the UE can ignore the flow ID.

[0050] In this case, the data transmission process of the UE is as follows: First, obtain the uplink data 1; then, according to the configuration information on the network side, that is, the DRB_1 of the UE only corresponds to flow_1, the uplink data 1 is processed at the PDAP layer, and the uplink data 1 is not processed at the PDAP layer. Carry flow_1; then, send uplink data 1 through DRB_1. After receiving the uplink data sent by the UE, the network side device can send the uplink data from DRB_1 through flow_1 on the network side according to th...

example 2

[0053] The above example 1 is for the case of no reflective QoS, but there may also be the case of reflective QoS, such as example 2.

[0054] In the second example, the sending end device is a UE, which corresponds to not carrying the flow channel identifier at the PDAP layer and having reflective QoS. The network side configures that one DRB (such as DRB_1) of the UE corresponds to only one flow ID (such as flow_1), and the network side indicates or agrees that one DRB corresponds to one flow ID, and the UE can ignore the flow ID.

[0055] In this case, the UE’s data transmission process is as follows: First, obtain the uplink data 2, and also receive the downlink reflective QoS in DRB_1, which corresponds to flow_2; then, according to the configuration information on the network side, process the uplink data 2 at the PDAP layer , uplink data 2 does not carry flow_1 at the PDAP layer, but uplink data 3 corresponding to reflective QoS must carry flow_2; then, uplink data 2 an...

example 3

[0057] The above examples 1 and 2 are for the case where the network side configures a certain DRB of the UE to correspond to only one flow ID, but the network side can also configure a certain DRB of the UE to correspond to multiple flow IDs, as in example 3.

[0058] In Example 3, the sending device is a UE, and the network side configures one DRB (such as DRB_1) of the UE to correspond to multiple flowIDs (such as flow_1, flow_2, flow_3), and the network side indicates a negligible flow ID (such as flow_1).

[0059] In this case, the data transmission process of the UE is as follows: first, obtain the uplink data 4 sent by the uplink for flow_1; then, according to the configuration information on the network side, process the uplink data 4 at the PDAP layer, and the uplink data 4 does not carry in the PDAP layer flow_1; then, send uplink data 4 through DRB_1. After the network side device receives the uplink data sent by the UE, if the uplink data from DRB_1 does not carry ...

Abstract

The present invention provides a data transmission method, a sending end device, and a receiving end device, wherein the data transmission method includes: acquiring first data, performing PDAP layer processing on the first data, and the first data is stored in the PDAP The layer does not carry the first data transmission channel identifier corresponding to the first data transmission channel, and sends the first data through the DRB corresponding to the first data transmission channel. The solution of the present invention can reduce the additional attribute information related to the data in the sent data, thereby saving signaling overhead.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method, a sending end device and a receiving end device. Background technique [0002] Currently, the fifth generation (5Generation, referred to as 5G) mobile communication system has introduced a Quality-of-Service (QoS) network-side indication mechanism. Therefore, it is necessary to add QoS indication information of the IP data flow of the terminal (such as flow channel identifier flow ID). Wherein, the flow ID is usually the information carried in the packet header of the newly added protocol layer, that is, the Packet Data Adaptation Protocol (PDAP for short) layer. For example, when the terminal UE sends uplink data, it needs to carry the flow ID in the PDAP layer header of the uplink data to indicate to the network side which data flow the uplink data belongs to on the network side of the UE; while the network side is receiving After re...
