Embodiment Construction

[0042] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0043] see figure 1 , the data processing method of the PDCP layer provided by the embodiment of the present invention can be applied to such as figure 1 in the application environment shown. understandably, figure 1 Only the corresponding layers directly related to the PDCP layer are shown in the base station, and other layers may also be included in the base station. The base station may be an LTE base station eNB, a 5G base station gNB, or other base stations including corresponding layers. After the PDCP layer receives the downlink data of the GTP layer, it wil...

Abstract

The present application relates to a data processing method of the PDCP layer, including: generating the latest PDCP PDU according to new data received from the GTP layer; judging whether the latest PDCP PDU is duplicated with the PDCP PDU currently sent to the RLC layer; if the latest The PDCP PDU is duplicated with the PDCP PDU currently sent to the RLC layer, and before the PDCP PDU currently sent to the RLC layer times out, the PDCP PDU currently sent to the RLC layer is immediately Perform timeout discard. By judging the data duplication between the latest PDCP PDU and the PDCP PDU currently sent to the RLC layer, the timeout discarding process is performed immediately on the PDCP PDU currently sent to the RLC layer that is duplicated with the latest PDCP PDU, which can effectively avoid discarding the latest duplicated data. When the PDCP PDU is sent to the RLC layer, the current PDCP PDU sent to the RLC layer is discarded due to timeout, resulting in the loss of the old and new PDCP PDUs at the same time, which effectively improves the reliability of data transmission and processing at the PDCP layer.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a data processing method, apparatus and base station of the PDCP layer. Background technique [0002] With the development of mobile communication technology, in the process of service data transmission in the mobile communication system, the user plane data from the network side is first parsed by the GTP (GPRS Tunnelling Protocol) layer of the packet wireless service tunneling protocol. Converged at the Packet Data Convergence Protocol (PDCP) layer, processed by the PDCP layer, and sent to the Radio Link Control layer (Radio Link Control, RLC) for transmission to the User Equipment (UE). In addition, according to the type of bearer service, data transmission is divided into Acknowledged Mode (AM) and Unacknowledged Mode (UM) transmission. AM mode has the function of Automatic Repeat Request (ARQ), which can guarantee Data is not lost during normal busin...
