Abstract: The present invention relates to the technical field of communications, and particularly relates to a method for selecting a path and device for addressing a problem in which a backhaul requirement of a small station flexibly deployed in a UDN cannot be satisfied by a method providing a single-hop backhaul path via pre-configuration or an OAM configuration. The path selection method provide in an embodiment of the present application comprises: transmitting, by a first node, a path request message for acquiring a backhaul path from the first node to the target node; and determining, by the first node, at least one backhaul path based on the received path indication message. The embodiment of the present invention enables a flexible and convenient determination of a backhaul path for a plug-and-play access point without needing to configure a single-hop backhaul path for the access point work of a network side. In addition, the embodiment of the present invention can be determine a multi-hop backhaul path for the first node based on actual requirements, thus improving probability for finding a backhaul path satisfying a backhaul requirement of the first node.
