Air interface converting method, data transmitting method, communication system and relevant equipment

Abstract

The embodiment of the invention discloses an air interface converting method, a data transmitting method, a communication system and relevant equipment, which are used for improving user experience. The air interface converting method comprises the following steps: receiving conversion preparation indication sent by a source base station by a user device; searching a target base station accordingto a gap of the conversion preparation indication for transmitting and receiving user data at an air interface, and synchronizing with the searched target base station; and entering the conversion interruption interval to executing the air interface conversion when meeting the preset condition. The embodiment of the invention also provides a data transmitting method, a communication system and relevant equipment.

Description

Technical field [0001] The invention relates to the field of communication, and in particular to an air interface switching method, a data transmission method, a communication system and related equipment. Background technique [0002] The handover scheme of Long Term Evolution (LTE) in the prior art includes three steps: handover preparation, handover execution, and source-side resource release. In order to prevent data loss during the handover, a forward forwarding link needs to be established. [0003] The forward forward link means that in the handover process of LTE, after the source base station (NB, NodeB) sends the Handover Command command, the source base station may still buffer data that needs to be sent to the user equipment (UE, User Equipment); in order to achieve Data is not lost during the handover, and a bearer link needs to be established between the source base station and the target base station so that the data buffered by the source base station can be forwar...

Problems solved by technology

[0011] Since the UE cannot send and receive user data during the handover interruption time, it will affect user experience. Therefore, it is necessary to shorten the handover interruption time as much as possible. However, the process of the UE collecting relevant information of the target base station and synchronizing with the target base station in the above-mentioned prior art will be difficult. It takes a lot of time, so the switching interruption time is too long and affects the user experience;

[0012] Secondly, in the above-mentioned prior art, it is necessary to establish a forward forwarding link between the source base station and the target base station during the handover preparation stage, so the system bearer will be occupied, thereby increasing the implementation complexity and wasting system resources
