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.

A mobile terminal and an operation mode switching method for a mobile terminal communication system are provided, the mobile terminal comprising at least a communication processor, wherein an operation mode in which the communication processor performs only a communication function is defined as a communication mode and an operation mode in which the communication processor performs both the communication function and an application function is defined as an application mode, the method comprising the following steps of acquiring, in the application mode, switching trigger information; and controlling the communication processor to switch from the application mode to the communication mode based on the switching trigger information. Also, in the communication mode, the system can also acquire switching information and switch from the communication mode to the application mode. The switching approach according to the present invention enables the communication processor to operate in the communication mode for performing the communication function only. Thus, the application function of the communication processor is not required to be started at all times, such that the occupation for the system resources as well as the system power consumption can be reduced.
