PRIMARY PATH SWITCHING METHOD AND SYSTEM, ELECTRONIC DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM

摘要

The embodiments of the present application relate to the technical field of wireless communications. Provided are a primary path switching method and system, an electronic device, and a computer-readable storage medium. The primary path switching method is applied to a first node, connected to a terminal, in a dual connectivity scenario or a multi-connectivity scenario, and the first node comprises a packet data convergence protocol layer corresponding to an off-loading bearer. The method comprises: acquiring bottom-layer state information of a node connected to a terminal, wherein the node connected to the terminal comprises a first node and at least one second node that does not comprise a packet data convergence protocol layer corresponding to an off-loading bearer, and the bottom-layer state information is used for indicating a link state between the terminal and the node; determining an optimal path according to the bottom-layer state information of the node connected to the terminal; and determining the optimal path as a primary path.
