Mobile Terminal Power Management for Priority Applications

The patent segments the power management approach by dividing applications into different priority levels (important applications versus other applications). The power management component selectively manages power allocation to different segments (applications) based on their priority, ensuring that important applications receive sufficient power while less critical applications may be restricted or shut down during low power states.

The patent implements preliminary action by having the power management component obtain power consumption information and reserving conditions of important applications in advance. Based on this pre-obtained information, the system calculates and reserves the necessary power for important applications before power depletion occurs, ensuring their continued functionality even when the terminal enters a low power state.

The patent applies local quality by implementing differentiated power management for different applications. Instead of a uniform shutdown approach, the system provides specialized power reservation and protection for important applications (such as phone call functions) while allowing other applications to be restricted or shut down. This localized quality assurance ensures that critical functions maintain operational capability even when the overall system is in a low power state.
