Claim 18:
19. A multi-link device, comprising:
a target network access device selection unit configured to select a network access device that meets a condition as a target network access device;
a first logical entity corresponding to a primary link of an original network access device, and configured to send a link disconnection request message to the original network access device to request a disconnection of a second logical entity from the original network access device and send, after a connection of the second logical entity with the target network access device has been established, 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; and
the second logical entity corresponding to a first secondary link of the original network access device, and configured to send a link disconnection request message to the original network access device to request the disconnection of the second logical entity from the original network access device, send an association request message to the target network access device after the disconnection from the original network access device, receive an association response message sent by the target network access device, and establish the connection with the target network access device,
wherein the second logical entity is configured to:
set, 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 set a corresponding network access device address as an address of the target network access device.
