Power supply control in a mobile portable device

A method for waking up a mobile portable device, said method comprises

• supplying power to the network communication module of the mobile portable device constantly, when the mobile portable device is in a power-off/sleep state, and
• activating the switching power supply to supply power to the mobile portable device and thus put the mobile portable device into an operating state, when detecting that the network communication module has received information from a network,
• wherein said network communication module comprises a wireless network module or a wired network adapter,
• and wherein when detecting the insertion of a subscriber identity identification card, activates the switching power supply and supplies power to the wireless network module by using an external AC power supply of the system power supply and the external battery or power of the battery, the wireless network module is connected to the power-on circuit via a first IO port.

A mobile portable device comprising a network communication module, a power-on circuit, a switching power supply, a system power supply and external battery and a calculation unit, wherein

• the system power supply and external battery constantly supplies power to the network communication module by using an external AC power supply or a power of the battery, when the mobile portable device is in a power-off/sleep state, and
• when the power-on circuit detects that the network communication module has received information from a network, it activates the switching power supply to supply power to the mobile portable device and thus put the mobile portable device into an operating state;
• wherein the network communication module comprises a wireless network module which is connected to the power-on circuit,
• when detecting the insertion of a subscriber identification card, the power-on circuit activates the switching power supply and supplies power to the wireless network module by using an external AC power supply of the system power supply and the external battery or the power of the battery.
