Abstract: A small cell resource configuration method and device for a wireless mobile network. The method comprises: receiving an access request initiated by a terminal and a measurement result of a small cell reported by the terminal, wherein the measurement result is obtained by measuring the small cell before the terminal initiates the access request; determining the small cell which serves the terminal according to the measurement result of the small cell; and configuring a transmission resource on the determined small cell for the terminal, or receiving an access request initiated by a terminal on a frequency point of a small cell, and configuring a transmission resource on the small cell for the terminal. Since small cell information is broadcast in a macro cell, a terminal can measure a small cell according to the received small cell information before initiating an access request, instead of performing measurement during an access process. Therefore, signalling interaction of configuring a transmission resource of a small cell for a terminal during an access process is reduced, thereby achieving the purpose of enabling the terminal to use the transmission resource of the small cell as soon as possible.

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.
