  • Publication number: 20160156549
    Abstract: A method of maintaining a network connection is used between an electronic apparatus and a server. The method includes the following steps: (a) sending an Nth test packet to the server, and the Nth test packet requests that the server reply to the electronic apparatus after waiting for an Nth time interval; (b) determining whether a reply for the Nth test package is received; (c) repeating step (a) if the reply for the Nth test packet is received; and calculating a period from the (N?1)th test packet being sent to the reply from the server being received if the reply for the Nth test packet is not received; and (d) sending a keep-alive packet periodically to the server according to the period for maintaining a connection between the electronic apparatus and the server when the electronic apparatus is switched to a standby/sleep mode.

  • Patent number: 9201663
    Abstract: A computer system and a remote control method for a computer device are provided. The computer system includes a computer device and a remote device. The computer device includes a network communication unit and an ID table. Before the computer device enters into a power-saving state, the computer device reads an ID code of the network communication unit and searches the ID table according to the ID code to obtain a particular packet format type. The computer device sends an agreement packet including a message of the particular packet format type to notify the remote device. The computer device receives a response packet from the remote device for setting a packet receiving procedure and enters into the power-saving state. When the computer device receives a wake-up packet compliant with the packet receiving procedure from the remote device, the computer device returns to a normal operation state.
