Abstract

The present invention provides a mobile computation device and a data packet reception method thereof. The mobile computation device comprising a network communication module and a mobile computation unit, wherein the mobile computation device has a power supply for supplying power to the network communication module when the mobile computation device is in a power-off status, so that the network communication module receives a data packet from a network when the mobile computation device is in a power-off status. The method comprises sending an instruction of initiating downloading of communication content upon the reception of the data packet from the network, powering on relevant hardware necessary for the downloading of the communication content, initializing the relevant hardware and starting software corresponding to the downloading of the communication content, and downloading communication content needed to be downloaded from the network to a local harddisk. The present invention enables real time reception of communication service, fast power-on and automatic power-off of the device and reduction in power consumption.
