Embodiment Construction

[0021] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the accompanying drawings required in the embodiments of the present invention. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For Those of ordinary skill in the art can also obtain other drawings based on these drawings without any creative effort.

[0022] In order to facilitate the understanding of the present invention, the conditional switching process of the embodiment of the present invention is described first. Optionally, the conditional switching process in this embodiment of the present invention mainly includes the following steps:

[0023] S1: The source node sends a handover request (handover request) message to no less than one (ie at least one) potential target node.

[0024] S2: Optionally, the potential target node performs access control on ...

Abstract

The invention provides a random access method and a terminal, and the method comprises the steps: obtaining a beam measurement result of at least one potential target cell; selecting a target cell from the at least one potential target cell according to the beam measurement result and a first condition switching triggering condition; and initiating a random access process on the target cell. According to the scheme of the invention, the beam measurement result can be introduced into the condition switching triggering condition, thereby achieving the condition switching process based on the beam measurement result, improving the switching success rate, and guaranteeing the communication efficiency.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a random access method and a terminal. Background technique [0002] In order to prevent the terminal from being unable to receive handover command-related messages from the source node after the channel condition of the source cell deteriorates, resulting in handover failure, a Conditional Handover (CHO) process is currently introduced. In the current CHO process, the terminal can judge whether the conditional handover trigger condition is met according to the cell measurement results of the source cell and / or the target cell, and when it is judged that the conditional handover trigger condition is met, the terminal performs the handover process and initiates a random call to the target node. Access process. [0003] However, since current network nodes can be configured with multiple Transmission Reference Points (TRP), terminals can initiate random access pro...
