Abstract: Embodiments of this application disclose an incoming call alert method and a terminal. The incoming call alert method includes: receiving an incoming call request; and invoking an audio/video player of a system to play audio/video corresponding to the incoming call request. The audio/video player is disposed in a system of the terminal in the embodiments of this application, so that when the terminal receives the incoming call request, the system of the terminal can play the audio/video used for incoming call alert. In this way, the terminal can alert a user by playing the audio/video without occupying additional system resources. In addition, an animation of the video and a caller ID display interface that are displayed by the terminal are integrated in terms of a visual effect, thereby improving use experience of the user.

Abstract: The present invention relates to the communications field, and in particular, to an antenna system. The antenna system includes: a transmit antenna, a receive antenna, a radome above the transmit antenna and the receive antenna, and a reflector within the radome, where a signal received by the receive antenna after a transmitted signal of the transmit antenna is reflected by the reflector offsets an intra-frequency interference signal generated because the transmitted signal of the transmit antenna is directly received by the receive antenna. As a result, according to the embodiments of the present invention, the intra-frequency interference signal of the transmit antenna to the receive antenna may be eliminated without increasing the number of antennas and a distance between antennas.
