Problems solved by technology

In this way, there will be a problem. If the PDCP entity receives the PDCP SDU from the upper layer, it immediately composes the PDCP PDU and sends it to the RLC entity, and the RLC entity quickly composes the RLC PDU and sends it out. The set time length is 1500ms. In this way, using the data processing method of the prior art, the PDCP entity will store 1500-50=1450ms more time for the PDCP SDU. In this way, the memory resources of the PDCP entity will be greatly wasted

Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] The data processing method provided by the present invention is applied between PDCP and RLC, and a connection is established between PDCP and RLC, such as figure 2 as shown, figure 2 The basic flowchart of the data processing method provided by the embodiment of the present invention, such as figure 2 As shown, the method mainly includes the following steps:

[0037] Step 201, RLC sends data from PDCP.

[0038] Step 202, the RLC sends a data transmission notification to the PDCP.

[0039] In step 203, the PDCP receives the data transmission notification, searches for corresponding data in its cached data according to the data transmission notification, and deletes the found data.

[0040] The above method provided by the present inv...

Abstract

The invention provides a data processing method, a data processing device, an RLC entity and a PDCP entity. The method comprises that: the radio link control RLC entity transmits data from the packet data convergence protocol PDCP entity and then transmits a data transmission notice to the PDCP entity; and the PDCP entity receives the data transmission notice, searches for the corresponding data from the cached data of the PDCP entity according to the data transmission notice and deletes the searched data. The data processing method is favorable for saving a storage space of the PDCP entity and improving the utilization ratio of the memory resources of the PDCP entity.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a data processing method, device, radio link control (RLC) entity and packet data convergence protocol (PDCP) entity. Background technique [0002] At present, in network communication technology, in order to ensure the validity of data transmission, usually at the PDCP layer, specifically, after the PDCP entity receives the PDCP service data unit (SDU) from the upper layer, the PDCP entity stores the PDCP SDU, wherein, the PDCP SDU In order to correspond to the data transmission block on the transmission channel, the reason why the PDCP entity stores the PDCP SDU is to send the received data according to the instructions of the bottom layer. If the bottom layer sends a required PDCP SDU information (the information carries the required The sequence number of the PDCP SDU) is indicated to the PDCP entity, then the PDCP entity searches for the corresponding PDCP SDU in t...
