Multi-standby Mobile Terminal Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual standby mobile terminals consume excessive power by continuously attempting to acquire unavailable communication systems, leading to increased power consumption and reduced standby and communication times.
Innovation Solution
A method and apparatus that detect communication events, acquire communication services, and control the operation of communication modules based on the acquired services, allowing the mobile terminal to adaptively switch between CDMA and GSM modes to reduce unnecessary operations and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the dual standby mobile terminal simultaneously supports both CDMA and GSM systems, then the adaptability and versatility of the terminal is improved, but the power consumption increases due to continuous operation of communication modules for both systems
Solution Approach 1:
The patent implements dynamic mode switching between CDMA and GSM systems based on service availability detection. The terminal transitions from a static dual-standby state to a dynamic state where the active communication mode is adjusted in real-time according to network conditions, thereby reducing power consumption while maintaining multi-system support capability
Solution Approach 2:
The patent changes the operational parameters of communication modules by disabling one system's communication module when its service is unavailable, while keeping the other system active. This parameter change (from both modules active to selective module activation) directly reduces power consumption while preserving the ability to switch modes when needed
2Reliability
If the dual standby mobile terminal periodically attempts to acquire unavailable systems, then the reliability of service acquisition is improved, but the power consumption increases and standby time decreases
Solution Approach 1:
The patent implements a periodic detection mechanism that checks for communication service availability at intervals rather than continuously. This periodic action maintains the ability to acquire services reliably while significantly reducing power consumption compared to continuous monitoring, thereby extending standby time
Solution Approach 2:
The patent applies partial action by performing service detection only when necessary (periodically or upon mode switching) rather than continuously. This partial monitoring approach maintains sufficient reliability for service acquisition while avoiding the excessive power consumption that would result from constant detection attempts

AI summary
A method and apparatus for saving power of a multi standby mobile terminal are provided that can reduce power consumption by limiting an unnecessary operation in a communication mode that does not perform a communication service in the multi standby mobile terminal. The method of saving power of a multi standby mobile terminal includes detecting whether a communication event is generated; acquiring, if a communication event is generated, a communication service; and operating the multi standby mobile terminal in a communication mode of the acquired communication service.
