Data processing method and related equipment

Abstract

The embodiment of the invention discloses a data processing method and related equipment, which are used for increasing the network throughput rate in a dual-connection scene. In the embodiment of the invention, after the target base station determines that the network element of the core network has completed the bearer change of inter-station switching, the target base station sends the first message to the network element of the core network, so that the core network establishes the user plane bearer of the terminal accessing the target base station between the auxiliary base station and the network element of the core network according to the first message. That is, the user plane bearer of the terminal accessing the target base station between the auxiliary base station and the network element of the core network. Once the target base station and the network element of the core network complete the bearer change, the process of adding the auxiliary base station is initiated through the first message, thereby avoiding the failure of adding the auxiliary base station as the auxiliary carrier by the target base station due to the fact that the core network cannot process the bearer change of the terminal between the target base station and the auxiliary base station at the same time in the process of processing the bearer change of inter-station switching. The auxiliary carrier adding success rate is increased, and the switching data off-channel delay is reduced, so that the network throughput rate of the base station after inter-station switching is increased, and the user experience is improved.

Description

technical field [0001] The present application relates to the communication field, and in particular to a data processing method and related equipment. Background technique [0002] Non-independent networking (NSA, non-standalone) and independent networking (SA, standalone) are two networking configuration forms of 5G air interface (NR, new radio) in the actual network development process. NSA is a networking solution that quickly provides 5G capabilities and enables large-scale deployment. Generally speaking, NSA can use dual connectivity (DC, dual connectivity), multi-radio technology dual connectivity (MR-DC, multi-radio dual connectivity), evolved terrestrial radio access (E-UTRA, evolved-UMTS terrestrial radio access ) and NR dual connectivity (EN-DC, E-UTRA-NR dualconnectivity) are realized. [0003] In the prior art, under the NSA architecture, taking EN-DC as an example, the core network is an evolved packet core network (EPC, evolved packet core) based on a 4G net...

Problems solved by technology

[0004] However, when a terminal accessing an eNB triggers an inter-site handover due to changes in signal quality, adjustment of wireless transmission service load, activation operation and maintenance, and equipment failure lights, etc., carrier transfer will occur, and the inter-eNB handover process and gNB addition There may be conflicts in the process. After the eNB is handed over between stations, the user throughput rate will decrease significantly. Similarly, the core network will also have the same problem when adding secondary carriers to other types under the NSA structure, making the user experience worse. Difference
