1. An electronic device, comprising processing circuitry configured to:
determine a topological position of an integrated access and backhaul (IAB) node in an IAB network at a next time instant according to a historical geographical position and a historical topological position of the IAB node, the topological position comprising a parent node and a donor node of the IAB node;
send a switching request to the donor node of the IAB node at the next time instant, to request that the IAB node is switched at the next time instant to the parent node and the donor node at the next time instant; and
send a switching notification to a donor node of the IAB node at a current time instant, the switching notification comprising the topological position of the IAB node at the next time instant, so that the IAB node is connected to both the donor node at the current time instant and the donor node at the next time instant on a control plane.
