1. A roaming method in a multi-link scenario, comprising:
selecting a network access device that meets a condition as a target network access device;
sending, by a first logical entity corresponding to a primary link of an original network access device or a second logical entity corresponding to a first secondary link of the original network access device, a link disconnection request message to request a disconnection of the second logical entity from the original network access device;
sending, by the second logical entity, an association request message to the target network access device after the disconnection of the second logical entity from the original network access device;
receiving, by the second logical entity, an association response message sent by the target network access device, and establishing a connection with the target network access device; and
sending, by the first logical entity after the second logical entity has established the connection with the target network access device, a disassociation request message to the original network access device to disconnect the first logical entity or disconnect the first logical entity and a logical entity other than the first logical entity and the second logical entity from the original network access device,
wherein the establishing, by the second logical entity, the connection with the target network access device comprises:
setting, upon the second logical entity is connected with target network access device while the first logical entity has not been disconnected from the original network access device, a primary or secondary link identifier corresponding to the second logical entity in a locally stored table of correspondence between logical entities and links as a temporary primary link, and setting a corresponding network access device address as an address of the target network access device.
