Problems solved by technology

[0004] However, in the fifth-generation mobile communication system (5-Generation, 5G), the base station and the terminal equipment have a data packet preprocessing function, that is, before the air interface has no transmission resources, the PDCP entity sends the PDCP PDU to the RLC entity, so that The RLC entity generates an RLC PDU. After PDCP re-establishment occurs, if the data sent by the PDCP entity to the RLC entity and the MAC entity is not sent through the air interface, and the RLC entity and the MAC entity will not retransmit the preprocessed data, resulting in data lost

Abstract

The invention provides a data processing method and device and a computer storage mediumWhen the PDCP entity of the UM DRB is reconstructed, the PDCP entity of the UM DRB is reconstructed. Alternatively, when a cell handover occurs and the PDCP entity of the UM DRB uses the key before the handover, the PDCP entity of the UM DRB uses the key before the handover. The PDCP entity determines a first SDU, where the first SDU is an SDU associated with a serial number by the PDCP entity and corresponding data is not transmitted through an air interface, and submits a PDU corresponding to the first SDU to the RLC entity. Through the re-submission of the data corresponding to the first SDU, the problem of data packet loss caused by the preprocessing of the PDCP entity is avoided.

Description

technical field [0001] The present application relates to communication technology, and in particular to a data processing method, device and computer storage medium. Background technique [0002] The wireless interface protocol stack is divided into three layers: physical layer, link layer and network layer. The link layer includes packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, radio link control (Radio Link Control, RLC) and media interface layer. Incoming control (Media Access Control, MAC) layer, PDCP layer is located above the RLC layer, RLC layer is located above the MAC layer. The PDCP layer is used to compress and decompress the packet header of user plane data, encrypt and decrypt user plane data, and protect the integrity of control plane data, etc., and sends the data to the RLC layer in sequence, and the order of data passes through the PDCP layer A sequence number (Sequence Number, SN) guarantee for data association. The RLC l...
