Θ民 /唤醒方法以及终端。 背景技术
通用串行总线 （ Universal Serial Bus , USB ) 端口的无线广域网络 ( Wireless Wide Area Network, WWAN )调制解调装置 （ MOdulator and DEModulator, MODEM )是通过个人计算机 ( Personal Computer, PC )的 USB端口供电的。 当 PC进入待机或休眠状态时， PC的 USB端口有些是 继续供电的。 发明人在实现本发明的过程中， 发现现有技术至少存在以下 缺点： 1 ) USB端口的无线 MODEM无法关闭， 导致在 PC待机或休眠时 仍然耗电。 2 ) USB WWAN Modem关闭后， 如果 PC重新从休眠中恢复， USB WWAN Modem无法自动启动， 需要重新插拔后才能启动。
一种情况是， 当 PC进入待机或休眠状态， 而 PC的 USB端口仍然继 续供电时， 通过 USB通信的无线 MODEM无法关闭。 这样会导致 PC无 法进入真正的待机或休眠状态， 无线 MODEM仍然在消耗 PC的电能。 这 样会影响 PC的待机或休眠的功能的使用， 并且减少 PC的使用寿命。
另一种情况是， 当 PC进入待机或休眠状态， 而 PC的 USB端口仍然 继续供电时， 通过 USB通信的无线 MODEM关机。 此时， 当 PC重新从 待机或休眠状态中恢复过来时， 因为一直处于供电状态的 USB 端口并没 有经过先断电再重新上电的过程， 通过 USB通信的无线 MODEM无法获 取到 PC的开机信号， 则无法重新打开。 用户必须先拔掉与 PC连接的无 线 MODEM, 然后重新***该无线 MODEM进行开机； 尤其是通过内置 PCI-e mini卡接口的 USB通信的无线 MODEM, 用户无法重新拔插无线 MODEM, 只能重新启动 PC。 发明内容
