Method for realizing bearer switching, terminal and eNB

Abstract

The invention discloses a method for realizing bearer switching, a terminal and an eNB. The method comprises the following step: when at least one data wireless bearer of the terminal needs to be switched from a source eNB to a target eNB, keeping data transmission between the terminal and the source eNB for the data wireless bearer needing to be switched in a bearer switching process till the terminal accesses the target eNB successfully. Through the technical scheme for realizing bearer switching provided by the invention, uplink data of a user plane data bearer needing to be switched in the terminal are always transmitted to the source eNB before the terminal succeeds in random access to the target eNB, and the terminal immediately starts working of a new wireless protocol stack while deleting an original wireless protocol stack of a switched bearer after the terminal succeeds in random access to the target eNB, thereby preventing long-time significant decrease in data throughput during execution of a bearer switching program, and improving the user experience.

Description

technical field [0001] The present invention relates to but not limited to wireless access network technology, especially a method for realizing bearer switching, a terminal and a base station. Background technique [0002] With the increasing demand of users for large data volume services and communication performance, communication systems have maintained rapid development. Today, as the fourth generation (4G, the fourth Generation) network is increasingly widely deployed, research on the fifth generation (5G, the fifth Generation) network technology has also been put on the agenda. 5G network strives to achieve an order of magnitude increase in data capacity, transmission speed and other aspects compared with 4G network, and can be applied to various scenarios at a lower cost, support various architectures, and be compatible with various terminals. [0003] In an increasingly complex communication system, a typical user plane architecture is: a user equipment (UE) with m...

Problems solved by technology

That is to say, during the execution of the bearer switching procedure, the S-GW cannot receive the uploaded data packets, which will cause large fluctuations in data throughput, which in turn will lead to large user plane performance degradation

It also caused a long-term and substantial drop in data throughput on the switched bearer and during the execution of the bearer switching program, which reduced user experience.
