Abstract: A method includes selecting N cells waiting to be camped on from a candidate cell list, decoding a Physical Broadcast Channel (PBCH) of each of the selected N cells waiting to be camped on, selecting, from at least one cell whose PBCH is successfully decoded, one cell as a cell continuing waiting to be camped on, and when a remaining minimum system information (RMSI) decoding result of the cell continuing waiting to be camped on indicates that the cell continuing waiting to be camped on meets a camping criterion, determining the cell continuing waiting to be camped on as the cell to be camped on.

Abstract: A terminal is disclosed, wherein a metal back cover of the terminal includes a slot. The slot divides the metal back cover into two parts. One of the two parts is used as an antenna radiator. The antenna radiator includes a signal feed point, a first ground point, and at least one second ground point, so that an antenna of the terminal has four resonance points. The signal feed point is connected to a matching network, the first ground point is grounded by a switch device, and the second ground point is grounded. A distance between the signal feed point and the first ground point is less than a distance between the signal feed point and the second ground point, and none of the signal feed point, the first ground point, and the second ground point is located in an end of the slot.
