Embodiment 1

[0094] figure 2 A schematic structural diagram of a data transmission system provided by an embodiment of the present invention, the data transmission system includes a source sender SDAP entity 201, a target sender SDAP entity 202, and a target sender PDCP entity 203; wherein,

[0095] The source sending end SDAP entity 201 is configured to determine the first SDAP PDU that has not been sent in the current Qos Flow when receiving a re-establishment indication, wherein the re-establishment indication is used to indicate switching from the source sending end SDAP entity to The target sending end SDAP entity; determine the first SDAP SDU corresponding to the first SDAP PDU, and send the first SDAP SDU to the target sending end SDAP entity 202;

[0096] The SDAP entity 202 at the target sending end is used to receive the first SDAP SDU, and determine the Qos Flow to which the first SDAP SDU belongs; The mapping relationship includes adding an SDAP header to the first SDAP SDU t...

Embodiment 2

[0111] On the basis of the above embodiments, in the embodiments of the present invention, the SDAP entity at the source sending end is specifically configured to send the first SDAP SDU to the target sender according to the order in which the first SDAP SDU is received. end SDAP entity.

[0112] The target sending end SDAP entity is specifically configured to send the fourth SDAP PDU corresponding to the first SDAP SDU to the target sending end PDCP entity corresponding to the target SDAP entity in accordance with the order in which the first SDAP SDU is received .

[0113] In order to avoid discontinuous data sending caused by the SDAP entity during the re-establishment process, the SDAP entity may send data in the order in which the data is received when sending data.

[0114] When the SDAP entity at the source sending end sends the first SDAP SDU to the SDAP entity at the target sending end, it may send the first SDAP SDUs to the SDAP entity at the target sending end sequ...

Embodiment 3

[0118] On the basis of the above-mentioned embodiments, in the embodiments of the present invention, the SDAP entity at the source sending end is further configured to, according to the service type of the current Qos Flow, if it is determined that the current Qos Flow needs to be confirmed, the The SDAP PDU that fails to pass the confirmation is determined as the first SDAP PDU that has not been sent.

[0119] In the actual data transmission process, some data involves business data, and the accuracy of the data analysis results is highly required. Therefore, the SDAP SDU corresponding to this type of data can be reprocessed by the SDAP entity of the target sender.

[0120] For the current Qos Flow, the SDAP entity at the source sender can identify the service type of the current Qos Flow. When the SDAP entity at the source sender identifies the service type of the current Qos Flow, it can save the service type corresponding to different Qos Flow, which can be the current Qos ...

Abstract

The invention discloses a data transmission method, device and system, an SDAP entity and a storage medium, and the method comprises the steps: an SDAP PDU which is not transmitted in the current QosFlow is determined when a source transmitting end SDAP entity receives a reestablishment instruction; an SDAP SDU corresponding to the SDAP PDU is determined, and the SDAP SDU is sent to a target sending end SDAP entity, so that the target sending end SDAP entity adds an SDAP header to the SDAP SDU according to the Qos Flow to which the SDAP SDU belongs and a mapping relationship between the Qos Flow stored by the target sending end SDAP entity and a data resource bearer DRB. According to the invention, a result obtained by analysis can be consistent with an analysis result which should be obtained, and the accuracy of the determined Reflective Qos can be ensured.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a data transmission method, device, system, SDAP entity and storage medium. Background technique [0002] In the 5G NR system, the SDAP (Service Data Adaptation Protocol) layer is introduced. The function of the SDAP layer is to transmit data on the user plane and realize the mapping from the Qos Flow (Qos Flow) of the uplink and downlink data to the DRB. Add a Qos Flow ID (Qos Flow ID) to the upstream and downstream data flows, and complete the reflective Qos mapping. [0003] The overall functional diagram of the SDAP layer is as follows figure 1 As shown, for the sending end, the SDAP layer maps the data on the Qos Flow to the DRB (Data Resource Bearer, data resource bearer) that satisfies the mapping relationship according to the saved mapping relationship between the Qos Flow and the DRB. The DRB is specifically used for terminals and DRBs. For data bearer betwee...
