Abstract: Embodiments of the present application relate to the field of wireless communications, and in particular, to a method and an apparatus for cell search in a sensor system, used for solving the problem in the prior art that an operation time delay is long in cell selection and cell residence. The method of the embodiments of the present application comprises: a terminal determining different types of frequency points in frequency points supported by the sensor system, the frequency points of the sensor system being divided, in a diminishing sequence of priorities, into a first type of authorization frequency point, a first type of non-authorization frequency point, a second type of authorization frequency point and a second type of non-authorization frequency point; and performing, in a diminishing sequence of priorities, cell search and cell residence on the frequency points supported by the sensor system. With the present application, a suitable cell can be selected fast and accurately to perform residence, thereby reducing the operation time delay in cell selection and cell residence after a terminal is started, and improving user experience.
