Hybrid Mobile Terminal HDR Power Save Mode Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hybrid mobile communication terminals experience delays in data call connections when operating in HDR power save mode due to inability to acquire the EVDO system, leading to inefficient service provision and battery consumption.
Innovation Solution
Implementing a method where the terminal sets an HDR power save mode indicator and alternates between attempting to acquire the 1x and EVDO systems based on the indicator's status, attempting to reacquire the EVDO system at regular intervals, and releasing the power save mode once EVDO is acquired, thereby preventing unnecessary attempts and reducing delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the hybrid terminal attempts to acquire the EVDO system when in HDR power save mode, then the terminal can potentially access high-speed data service, but it causes delay in data call connection when EVDO is unavailable
Solution Approach 1:
The patent applies dynamics by making the system acquisition behavior adaptive rather than static. The terminal dynamically adjusts its acquisition strategy based on the HDR power save mode indicator: when the indicator is set (EVDO unavailable), it directly acquires 1x system; when not set, it attempts EVDO first. This dynamic adjustment eliminates unnecessary delays while maintaining the ability to access high-speed data when available.
Solution Approach 2:
The patent changes the operational parameter of system acquisition priority based on the HDR power save mode indicator state. By detecting the indicator parameter, the terminal switches between two acquisition modes: EVDO-priority mode (when indicator is not set) and 1x-direct mode (when indicator is set). This parameter-based control resolves the contradiction by adapting behavior to current system conditions.
2Productivity
If the hybrid terminal continuously attempts to acquire the EVDO system, then it can ensure high-speed data service availability, but it increases battery consumption
Solution Approach 1:
The patent implements periodic action by having the terminal check the HDR power save mode indicator before initiating EVDO system acquisition attempts. Instead of continuous monitoring and attempting, the terminal performs acquisition attempts only when the indicator shows EVDO is available. This periodic checking approach maintains high-speed data service availability while significantly reducing unnecessary battery consumption during EVDO outages.
Solution Approach 2:
The patent extracts the decision-making logic from continuous operation by using the HDR power save mode indicator to determine when EVDO acquisition attempts should occur. The indicator acts as a gate that extracts unnecessary acquisition attempts when EVDO is unavailable, allowing the terminal to skip battery-consuming operations while maintaining service availability when conditions permit.
3Use of energy by moving object
If the hybrid terminal operates in 1x_Only mode by setting HDR power save mode, then it reduces battery consumption, but it loses access to high-speed data service when available
Solution Approach 1:
The patent resolves this contradiction through dynamic mode switching based on the HDR power save mode indicator. Rather than statically operating in 1x_Only mode, the terminal dynamically transitions between 1x-direct mode (when indicator is set, saving battery) and EVDO-priority mode (when indicator is not set, enabling high-speed data). This dynamic behavior allows the terminal to optimize battery consumption while capturing high-speed data opportunities when available.

AI summary
Disclosed are a hybrid mobile communication terminal and a method of acquiring a system for data service in the hybrid terminal. The hybrid terminal includes a mode setting unit which sets an HDR power save mode and an indicator indicating the HDR power save mode when data service cannot be provided through the EVDO system; and a data communication unit which attempts to acquire the 1x system or the EVDO system according to whether the indicator has been set by the mode setting unit. The method includes: setting an HDR power save mode and an indicator indicating the HDR power save mode when the data service cannot be provided through the EVDO system; determining whether the indicator has been set upon acquiring a system for the data service; and attempting to acquire the 1x system or the EVDO system according to whether the indicator has been set.
