Abstract: A folder management method and device. The method includes: displaying a folder icon comprising a set of icons of at least two applications, and the set of icons is displayed as a thumbnail icon, and, in the thumbnail icon, each of the icons of the at least two applications is displayed in a shrunk size, and the folder icon further comprising an enlarged first icon associated with a first application, wherein the enlarged first icon is displayed adjacent to the thumbnail icon without the first icon, and wherein a size of the enlarged first icon is a same size as the thumbnail icon. The first application is determined according to a use time sequence or other factors. In this way, icons, of some applications, in the folder icon can be enlarged for display, which facilitates management of applications in the folder.

Abstract: The present invention is applicable to the communications field and provides a processing method for an orthogonal frequency division multiplexing (OFDM) signal and a network device. The processing method includes: obtaining an orthogonal frequency division multiplexing OFDM signal; multiplying, in a digital domain, the obtained OFDM signal by a simple harmonic wave whose frequency is fs to obtain a frequency shifted signal; and outputting and loading the frequency shifted signal by using a digital-to-analog conversion (DAC) to a driver and a modulator to send the frequency shifted OFDM signal.

Abstract: A VRRP fault detection method is applied to a VRRP group including one primary router and one or more secondary routers. The method includes: sending, by the primary router and the secondary router, link detection packets having an echo response function, where a destination address of the link detection packet is a virtual address of the VRRP group. The method also includes determining, by the primary router and the secondary router, whether response packets corresponding to the link detection packets sent by the primary router and the secondary router are received within a predetermined time, and if the primary router and/or the secondary router does not receive the response packet within the predetermined time, determining that the primary router is faulty.
