1. A self-backhaul network migration method performed by a first integrated access and backhaul (IAB) network node, comprising:
receiving network migration commands, wherein the network migration commands comprise a first network migration command and a second network migration command, the first network migration command is used to instruct the first IAB network node to migrate from a source donor IAB network node to a target donor IAB network node, and the second network migration command is used to instruct other network nodes to migrate from the source donor IAB network node to the target donor IAB network node, the other network nodes being downstream network nodes of the first IAB network node in a migrating IAB network; and
sending, after the first IAB network node migrates to the target donor IAB network node according to the first network migration command, the second network migration command to a second IAB network node or user equipment UE served by the first IAB network node, wherein the second IAB network node is a child IAB network node of the first IAB network node.
