The invention discloses a method for maintaining the connection of a terminal and a network server. The terminal comprises a first processing unit comprising a first state and a second state, wherein the power consumption of the second state is smaller than the power consumption of the first state. When the first processing unit is in the second state, the terminal or the network server is used for periodically transmitting a heartbeat data packet to maintain the connection of the terminal and the network server. According to the invention, when the terminal or the network server is used for periodically transmitting the heartbeat data packet, a main processor of the terminal can not be waked up, thereby the terminal which is in a dormancy state can maintain connection with the network server and can not be waked up for the heartbeat data packet transmitted by the network server, and therefore, the power consumption of the terminal can be reduced.
