Embodiment Construction

[0089] In order to make the above objects, features 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 specific embodiments.

[0090] In the implementation scheme of EN-DC (E-UTRA-NRDual Connectivity, 4G-5G dual connection) based on NSA's option3X (3X option of 5G network deployment mode architecture) architecture, through SN addition (Secondary Nodeaddition, secondary node addition ) process to migrate the default service bearer from 4G to 5G side, and downlink services are sent from the service server to the PDCP (Packet Data Convergence Protocol, Packet Data Convergence Protocol) of the 5G base station through the NG link. The two links of RLC (Radio Link Control, Radio Link Control Protocol) and 5G RLC are delivered to the terminal side.

[0091] Among them, refer to figure 1 , shows a schematic diagram of the option3X architecture. The option3...

Abstract

An embodiment of the present application provides a method for processing downlink data. The method includes: if the 4G base station receives the preset information, then acquire and send the configuration information to the terminal, after receiving and saving the configuration information, the terminal performs downlink signal measurement to obtain the SINR value, and sends the SINR value to the 4G base station, and the 4G base station will The SINR value is transparently transmitted to the 5G base station. The 5G base station determines the amount of offloaded data according to the SINR value, and obtains the offloaded data packet corresponding to the amount of offloaded data from the downlink data and sends it to the 4G base station. The 4G base station sends the offloaded data packet to the terminal, thereby Realized that the 5G base station obtains the downlink SINR signal strength of the terminal under the coverage of the 4G network in real time, so as to judge the amount of offload data that the 4G base station can support, so that the 5G base station can allocate offload data for the 4G base station more reasonably and accurately, without causing While the data is piled up on the side of the 4G base station, it is guaranteed to maximize the use of 4G network resources.

Description

technical field [0001] The present application relates to the technical field of downlink data processing, and in particular, to a downlink data processing method and a downlink data processing device. Background technique [0002] At present, in the construction of 5G (The 5th Generation mobile communication technology, fifth generation communication technology) network, the NSA scenario (Non-Standalone, non-independent networking) is the main means in the network construction. The NSA scenario refers to the networking method of using the existing 4G (The 4th Generation mobile communication technology, fourth-generation communication technology) infrastructure to deploy 5G networks. [0003] The option3X in the NSA scenario is the current priority network construction method. The option3X architecture migrates the service bearer to the 5G side through EN-DC (E-UTRA-NR DualConnectivity, 4G-5G dual connectivity). When performing downlink data transmission, the 5G side base s...
