Problems solved by technology

[0006] The technical problem mainly solved by the present invention is to provide a communication handover method and device, which can solve the ping-pong problem caused by the user equipment staying in a wireless environment that satisfies the trigger condition but does not meet the handover condition in the prior art, thus bringing a lot of resources and power consumption Problems with waste and signaling overhead

Embodiment Construction

[0028] 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.

[0029] The execution subject of the first embodiment of the communication switching method of the present invention is user equipment (User Equipment, UE), and the user equipment can be fixed or mobile, and can be a cellular phone, a personal digital assistant (PDA), a wireless modem, a tablet Computers, laptops, cordless phones, etc. Such as figure 1 As shown, this embodiment includes:

[0030] S11: The user equipment determines whether the number of times condition switching is initiated or condition switching is not completed within a preset time is greater than a preset threshold.

[0031] Initiating a conditional handover may include sending a measurement report to a source base station, ie, a base station of a cell to which the UE is currently connected. The U...

Abstract

The invention discloses a communication switching method, and the method includes the steps that user equipment / a base station determines whether the number of times that the conditional switching isstarted or the conditional switching is not completed within a preset time period is greater than a preset threshold value or not: if the number of times is greater than the preset threshold value, the user equipment / the base station stops the starting of the conditional switching / configures new conditional switching within a preset time period. The invention also discloses a communication switching device. In the above manner, the method can prevent the user equipment from being in a ping-pong problem when the wireless environment satisfies the trigger condition but does not satisfy the switching condition, thereby reducing resource and power consumption waste and signaling overhead.

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, a conditional handover (i.e. autonomous handover) is proposed. Specifically, the user equipment measures the meas...
