Disclosed are a power-saving method for a user terminal and a device, for resolving a problem in the prior art in which changing a resident cell of a user terminal leads to relatively large power consumption. The method comprises: in the process of changing the resident cell of a user terminal from a first cell to a second cell, the user terminal, when in the first cell, receiving first acquisition information from a first base station corresponding to a first cell for acquiring network location information, and when in the second cell, receiving network location information issued by a second base station corresponding to a second cell; the user terminal determining whether a network location identifier for the second cell in the network location information issued by the second base station is included in a list of network location identifiers of the user terminal; and if so, the user terminal receiving, based on second acquisition information received while in the first cell from the first base station for acquiring a wake-up signal, a wake-up signal issued by the second base station, so as to return to an operating state based on the wake-up signal and to receive a paging message.
