In recent years, with the rapid development of mobile communication technology, mobile communication terminals are more and more widely used, their functions are becoming more and more powerful, and their power consumption is also increasing. For portable mobile terminals, most of them are small in size and rely on batteries for power supply, and are often required to have a long standby and use time, which puts forward higher requirements on the system power consumption of the terminal in order to maximize the The purpose of power saving.

The terminal usually includes a communication processor and an application processor. The communication processor is responsible for the baseband communication, and the application processor is responsible for the application software processing of the terminal. However, this requires high hardware and the utilization rate of the communication processor is low. Increased costs.

Since the power-saving processing system in the mobile terminal includes a baseband module and an application module, and the baseband module and the application module share a processing unit, the baseband module includes a monitoring unit and a first judging unit, and the application module includes an external device, the monitoring unit first The task monitoring of the baseband module is carried out, and the task processing of the baseband module is carried out by the processor, which ensures that the tasks in the baseband module with high real-time requirements are processed in time, and the status of the application module is checked after the tasks in the baseband module are processed. Detect, and when the application module is in the working state, the processor performs the task processing of the application module. When the application module is in the dormant state, the baseband module queries its own sleep type. When the sleep condition is met, the baseband module enters the sleep state , reduces power consumption, prolongs the use time of the mobile terminal, and due to the introduction of the virtual operating system, the communication between the baseband module and the application module is enabled, so that only one processor can realize the tasks of the baseband module and the application module at the same time scheduling.

Therefore, the power-saving processing system enables the mobile terminal to enter the sleep time as much as possible and extend the sleep time as much as possible, so that the power consumption of the mobile terminal is reduced, and the cost is reduced at the same time.

At the same time, in the above embodiments, the descriptions of each embodiment have their own emphases, and for the parts not described in detail in a certain embodiment, refer to the relevant descriptions of other embodiments.

A power-saving processing method, system, and mobile terminal for a mobile terminal provided by the embodiments of the present invention have been described above in detail. In this paper, specific examples are used to illustrate the principle and implementation of the present invention. The description of the above embodiments It is only used to help understand the method of the present invention and its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation and scope of application. In summary, The contents of this description should not be construed as limiting the present invention.
