a sleep/wake-up circuit unit connected to the USB port and configured to send a notification signal to a central processing unit (CPU) of the wireless modem device according to the received action signal to enable the wireless modem device to sleep or wake up.

2. The wireless modem device according to claim 1, wherein the action signal is a standby/sleep signal or a wake-up signal of the terminal or a suspend signal or a resume signal of a USB, and the suspend signal and the resume signal are respectively obtained by converting the standby/sleep signal and the wake-up signal.

3. The wireless modem device according to claim 2, wherein the sleep/wake-up circuit unit comprises:

a selection circuit module connected to the USB port and configured to recognize and select the standby/sleep signal or the suspend signal or the wake-up signal or the resume signal input from the USB port;

a sleep circuit module selected to be triggered when the selection circuit module recognizes a received signal as the standby/sleep signal or the suspend signal, wherein the sleep circuit module is configured to send a first notification signal to the CPU so that the wireless modem device enters a sleep state or a suspend state; and

a wake-up circuit module selected to be triggered when the selection circuit module recognizes a received signal as the wake-up signal or the resume signal, wherein the wake-up circuit module is configured to send a second notification signal to the CPU to wake up or resume the wireless modem device.

4. The wireless modem device according to claim 1, further comprising:

a power supply circuit connected to the USB port and configured to output a power supply signal to supply power to the sleep/wake-up circuit unit and the CPU.

5. A terminal, comprising:

a universal serial bus (USB) port configured to connect to a wireless modem device through a serial bus and provide an action signal to the wireless modem device; and

a modem drive unit connected to the USB port and an operating system of the terminal, and configured to receive a sleep signal, a standby signal or a resume signal of the terminal sent by the operating system and convert the received signal into an action signal for driving the wireless modem device to output the action signal to the wireless modem device through the USB port, wherein the action signal is a standby/sleep signal or a wake-up signal of the terminal or a suspend signal or a resume signal of a USB.

6. The terminal according to claim 5, wherein the modem drive unit comprises:

a receiving subunit configured to receive the sleep signal, the standby signal or the resume signal of the terminal sent by the operating system;

a first conversion subunit configured to convert the sleep signal or the standby signal of the terminal into the standby/sleep signal of the terminal or convert the resume signal of the terminal into the wake-up signal of the terminal; and

a second conversion subunit configured to convert the standby/sleep signal of the terminal into the suspend signal of the USB or convert the wake-up signal of the terminal into the resume signal of the USB.

7. A wireless modem device sleep/wake-up method, comprising:

receiving an action signal obtained from a terminal through a serial bus; and

sending a notification signal to a central processing unit (CPU) of a wireless modem device according to the received action signal to enable the wireless modem device to sleep or wake up.

8. The wireless modem device sleep/wake-up method according to claim 7, wherein the receiving the action signal obtained from the terminal through the serial bus comprises:

receiving a standby/sleep signal of the terminal or a suspend signal of a universal serial bus (USB) through the serial bus; and

the sending the notification signal to the CPU of the wireless modem device according to the received action signal to enable the wireless modem device to sleep or wake up comprises;

converting the standby/sleep signal of the terminal or the suspend signal of the USB into a first notification signal, and sending the first notification signal to the CPU of the wireless modem device to instruct the wireless modem device to enter a sleep state or a suspend state.

9. The wireless modem device sleep/wake-up method according to claim 7, wherein the receiving the action signal obtained from the terminal through the serial bus comprises:

receiving a wake-up signal of the terminal or a resume signal of a USB through the serial bus; and
