Solution Overview

Problem

Multi-mode mobile terminals continuously consume unnecessary power due to frequent scanning and maintenance of connections with local networks, even when not in use or outside defined service zones, leading to increased power consumption and average AP scan time.

Innovation Solution

Implementing a hibernation mode that turns on/off the communication module for accessing a local network based on previously defined location information, allowing the module to be activated only at user-defined locations and deactivated elsewhere, thereby reducing power consumption and AP scan time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the multi-mode mobile terminal continuously performs scan operations for local network and maintains connection with mobile communication network, then the terminal can access wireless services through AP and prevent breaking from local network, but the terminal consumes unnecessary power continuously

Engineering Contradiction:
Improveconnection stabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the communication module's operational state changeable between active and hibernation modes based on location conditions. The controller dynamically adjusts the module's state according to whether the terminal is in a defined service zone, transforming a static continuous operation into a dynamic conditional operation that adapts to environmental changes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameter of the communication module from continuous operation to conditional operation based on location parameters. By monitoring location information and comparing it with stored service zone data, the system changes the module's state parameter between active and hibernation, optimizing power consumption while maintaining connection reliability when needed.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the multi-mode mobile terminal performs periodic scan operations to scan local network with highest preference, then the terminal can maintain access capability, but the scan operation takes unnecessary time when AP does not exist

Engineering Contradiction:
Improveaccess capabilityVSAvoidscan time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by checking location information before performing scan operations. The controller first determines whether the terminal is in a defined service zone using stored location data, and only if the condition is met does it proceed with scanning and connection operations. This preliminary check prevents unnecessary scan operations and associated time loss when no AP is available in the current location.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the multi-mode mobile terminal maintains connection with mobile communication network while connected to local network, then the terminal can prevent breaking from local network, but the terminal performs unnecessary connection and scan operations when using only one network

Engineering Contradiction:
Improveconnection stabilityVSAvoidconnection management
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the unnecessary dual-network connection maintenance function by implementing location-based conditional control. When the terminal is determined to be outside a defined service zone or in hibernation conditions, the controller stops maintaining the mobile network connection, extracting only the essential local network connection function. This reduces connection management complexity while preserving reliability when actually needed.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A method and apparatus minimize current consumption related to accessing a local network in a multi-mode mobile terminal. Current location information of the multi-mode mobile terminal is checked through a first communication module. A second communication module for a local network is turned-on when the current location information of the multi-mode mobile terminal corresponds to stored location information. The second communication module is turned-off when a connection to the local network is interrupted and the current location information of the multi-mode mobile terminal does not correspond to the stored location information.
