In at least one embodiment, when receiving the incoming call signal, the smart call device 3 compares the identification in the incoming call signal with the stored identification of the smart call device 3. When the identification in the incoming call signal is identical with the stored identification of the smart call device 3, the smart call device 3 determines a target face image corresponding to the identification of the incoming call signal from the relationship table, acquires the face images through the image acquisition unit 32, and compares the acquired face images with the target face image. When one acquired face image matches with the target face image, the smart call device 3 sends a first control signal to the first handheld device 2. When the receiving module 12 receives the first control signal, the control module 13 sends text message to call the second handheld device 4 bound with the smart call device 3. When none of the acquired face image matches with the target face image, the smart call device 3 sends a second control signal to the first handheld device 2. When the receiving module 12 receives the second control signal, the control module 13 sends a voice message to the second handheld device 4 bound with the smart call device 3 to prompt the user of the second handheld device 4 as to the incoming call. For example, the text message can be “number XXX called you at . . . time . . . date . . . , please reply.”

In at least one exemplary embodiment, when receiving the incoming call signal, the smart call device compares the identification of the incoming call signal with the stored identification of the smart call device 3. When the identification of the incoming call signal is identical with the stored identification of the smart call device 3, the smart call device 3 acquires the face images through the image acquisition unit 32.
At block 605, the smart call device compares the acquired face images with stored user face of the second handheld device. In at least one exemplary embodiment, the smart call device determines a target face image corresponding to the identification of the incoming call signal from the relationship table, and compares the acquired face images with the target face.
At block 606, the smart call device sends a control signal to the first handheld device according to a comparing result. When the target face image is matched with one acquired face image, the smart call device sends a first control signal to the first handheld device. When none of the acquired face images match the target face image, the smart call device sends a second control signal to the first handheld device.
At block 607, the first handheld device calls the second handheld device bound with the smart call device in response to the control signal.
The method further includes: when receiving the first control signal, the first handheld device sends text message to call the second handheld device bound with the smart call device; or when receiving the second control signal, the first handheld device sends a voice message to the second handheld device bound with the smart call device to prompt the user of the second handheld device.
