Embodiment Construction

[0089] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[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), through SN addition (Secondary Nodeaddition, secondary node addition ) process to migrate the default service bearer from 4G to 5G, and the downlink service is sent from the service server to the PDCP (Packet Data Convergence Protocol) of the 5G base station through the NG link. After receiving the downlink data, the PDCP passes through the 4G Two links, 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 op...

Abstract

The embodiment of the invention provides a downlink data processing method. The method comprises the steps: if a 4G base station receives preset information, acquiring the configuration information and sending the configuration information to a terminal; enabling the terminal to receive and store the configuration information, then carrying out downlink signal measurement to obtain an SINR value and sending the SINR value to the 4G base station; enabling the 4G base station to transmit the SINR value to a 5G base station in a transparent mode, and enabling the 5G base station to determine the distribution data volume according to the SINR value obtaining the shunting data packet corresponding to the shunting data volume from the downlink data, and sending the shunting data packet to the 4G base station; and enabling the 4G base station to send the shunting data packet to the terminal, so that the 5G base station obtains the downlink SINR signal intensity of the terminal under the coverage of the 4G network in real time, so as to judge the shunting data volume supported by the 4G base station; therefore, the 5G base station can distribute the shunt data to the 4G base station more reasonably and accurately, the phenomenon of data accumulation at the 4G base station side is avoided, and the maximum utilization of 4G network resources is ensured.

Description

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