Abstract: A location movement method for a self-mobile node, and a related device are provided. A self-mobile node can move to a corresponding initial to-be-assisted location range according to initial to-be-assisted location information determined by the self-mobile node or determined by a control device; and after moving to the initial to-be-assisted location range, can move to a final finely adjusted to-be-assisted location range according to finely adjusted to-be-assisted location information determined by the self-mobile node or determined by the control device, and provide an assistance service for another to-be-assisted node within the final to-be-assisted location range. Therefore, a currently existing problem is resolved: Because a precise indoor map cannot be obtained, a self-mobile node cannot move to an accurate to-be-assisted area based on an indoor map. As a result, accuracy and applicability of on-demand movement of the self-mobile node are improved.
