A service signal processing method includes obtaining signal strength information of a current service antenna, and obtaining signal strength information of another service antenna; selecting a working antenna according to the signal strength information of the current service antenna and the signal strength information of the another service antenna; and controlling the working antenna to process a service signal of a current service using a radio frequency channel of the current service antenna. The working antenna determined according to the signal strength information of the current service antenna and the signal strength information of the another service antenna may be the current service antenna or may be the another service antenna. When multiple working antennas are determined, the working antennas may process a same service or may process different services.
