Embodiment Construction

[0053] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. Non-conflicting ones in the following embodiments can be combined with each other.

[0054] The execution subject of the first embodiment of the communication handover method of the present invention is a base station, and the base station serves as a source base station during the handover process, that is, a base station to which a user equipment (User Equipment, UE) is currently connected. The base station is connected to the core network and communicates wirelessly with the user equipment to provide communication coverage for the corresponding geographical area. The base station may be a macro base station, a micro (micro) base station, a pico (pico) base station or a home base station (femtocell). In some embodiments, a base station may also be called a wireless base station, an access point, a Node B, an evolved Node B (eNodeB, eNB), a gNB or oth...

Abstract

The invention discloses a communication switching method. The method includes steps: a source base station receives a measuring report reported by user equipment; the source base station selects a candidate base station for the user equipment according to the measuring report; the source base station transmits an automatic switching instruction to the user equipment, wherein the automatic switching instruction comprises information of the candidate base station and a switching condition; the source base station monitors whether a first switching confirmation message reported by the user equipment is received; and if the first switching confirmation message is received, the ongoing transmission is stopped, and a subsequent switching process is executed. The invention also discloses a communication switching apparatus. According to the method and apparatus, the resource waste can be reduced, and the switching interruption time is shortened.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication switching method and device. Background technique [0002] Handover is the most basic and important process in mobility management. In LTE / LTE-A, handover of user equipment is controlled by the base station. In NR, due to the use of high-frequency carrier and beamforming technology, the channel state changes rapidly, which may cause the source base station, that is, the base station to which the user equipment is currently connected, to fail to send a handover command to the user equipment. Once this happens, the control signaling between the user equipment and the base station disappears, and the user equipment will enter Radio Link Failure (RLF) and perform RRC re-establishment, resulting in a longer delay. [0003] In order to solve this problem, an autonomous handover is proposed, that is, the source base station sends an early handover command to the user ...
