Description

TECHNICAL FIELD

The present invention relates to the field of communication technologies, and in particular, to a wireless modem device, a wireless modem system, a wireless modem device sleep/wake-up method, and a terminal.

BACKGROUND

A Wireless Wide Area Network (Wireless Wide Area Network, WWAN) MOdulator and DEModulator (MOdulator and DEModulator, MODEM) device of a Universal Serial Bus (Universal Serial Bus, USB) port is powered by a USB port of a Personal Computer (Personal Computer, PC). When the PC enters a Standby or Sleep state, some USB ports of the PC stay powered. During implementation of the present invention, the inventor finds that the prior art has at least the following disadvantages: 1) The wireless MODEM of the USB port cannot be turned off, which still consumes power when the PC is in a Standby or Sleep state; 2) after the USB WWAN Modem is turned off, if the PC resumes from the Sleep state, the USB WWAN Modem cannot be started automatically and can only be started through unplugging and plugging.

In one situation, when the PC enters the Standby or Sleep state and the USB port of the PC still stays powered, the wireless MODEM communicating through the USB cannot be turned off. In this case, the PC cannot really enter the Standby or Sleep state, and the wireless modem still consumes the electrical energy of the PC. Therefore, the Standby or Sleep function of the PC is affected, and the use life of the PC is reduced.

In another situation, when the PC enters the Standby or Sleep state and the USB port of the PC still stays powered, the wireless modem communicating through the USB is turned off. At this time, when the PC resumes from the Standby or Sleep state, since the USB port that stays powered does not go through a process of being powered off and then powered on, the wireless MODEM communicating through the USB cannot obtain a startup signal of the PC, so the wireless MODEM cannot be turned on again. A user has to unplug the wireless MODEM connected to the PC first and then plug the wireless modem again to turn on the wireless MODEM. Especially, for the wireless MODEM communicating through the USB of a built-in Peripheral Component Interconnect Express (PCI-e) mini card interface, the user cannot unplug and plug the wireless modem again, so the PC has to be restarted.
