Method for maintaining connection between terminal and network server, terminal and network server

摘要

A method for maintaining the connection between a terminal and a network server is described. The terminal has a first processing unit with a first state and a second state, wherein the power consumption of the second state is less than the power consumption of the first state. When the first processing unit is in the second state, the terminal or the network server sends heartbeat data packets periodically in order to maintain the connection between said terminal and said network server. During the period that the terminal or the network server sends a periodic heartbeat data packet, a main processor of the terminal will not be woken up Thus, the terminal in a sleep state can maintain connection with the network server, and not be woken up due to the heartbeat data packets sent by the network server, which reduces the power consumption of the terminal.

1. A method for maintaining a connection between a terminal and a network server, said terminal having a first processing unit and a second processing unit, said first processing unit being a main processing unit that has a first state and a second state, a power consumption of said first processing unit in said second state being less than a power consumption of said first processing unit in said first state, said second processing unit being a communication functional unit, wherein a power consumption of said second processing unit is less than said power consumption of said first processing unit in said first state said method comprising:
said second processing unit of said terminal periodically transmitting a heartbeat data packet to said network server to maintain the connection between said terminal and said network server when said first processing unit of said terminal is in said second state, wherein said heartbeat data packet is generated and transmitted to said second processing unit by said first processing unit before said first processing unit enters said second state, and said network server determines not to transmit a feedback data packet to said terminal after said network server receives said heartbeat data packet or said network server periodically transmitting another heartbeat data packet to said second processing unit of said terminal, to maintain the connection between said terminal and said network server when said first processing unit of said terminal is in said second state.
