Solution Overview

Problem

Existing mobile stations require user intervention or coordination with a base station to reactivate inactive communication interfaces, leading to inefficiencies in power management and service level optimization.

Innovation Solution

A method is implemented in a mobile station to assess and compare the communication service levels of multiple communication interfaces, activating and deactivating them between active and inactive power modes based on predetermined thresholds and geographic conditions to optimize power consumption and service quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If communication interfaces are deactivated to save power, then power consumption is reduced, but reactivation requires user intervention or base station coordination which increases complexity and time delay

Engineering Contradiction:

Improvepower consumptionVSAvoidreactivation complexity

Core Design Contradiction:

Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The mobile station autonomously determines when to activate or deactivate communication interfaces by assessing communication service levels and comparing them against thresholds, eliminating the need for user intervention or base station coordination for reactivation decisions

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system pre-assesses communication service levels and prepares activation decisions before actual activation is needed, allowing interfaces to be reactivated quickly by simply switching power states rather than requiring complex reconfiguration procedures

Inventive Principle:

Principle #10Preliminary action

2Reliability

If communication interfaces remain active to ensure service availability, then service quality is maintained, but power consumption increases

Engineering Contradiction:

Improveservice availabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the power state of communication interfaces based on real-time assessment of communication service levels, transitioning interfaces between active and inactive states to match actual service requirements rather than maintaining a fixed state

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of communication interfaces by switching between active and inactive power modes based on assessed communication service levels, allowing the interface to adapt its power consumption to the actual service quality requirements

Inventive Principle:

Principle #35Parameter changes

3Reliability

If multiple communication interfaces are activated simultaneously, then service level redundancy is improved, but power consumption and device complexity increase

Engineering Contradiction:

Improveservice level redundancyVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system activates communication interfaces selectively based on whether the assessed service level meets predetermined thresholds, activating only the necessary number of interfaces rather than all available interfaces, thus achieving adequate service redundancy without excessive power consumption

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A method of providing communication services for a mobile station having a plurality of communication interfaces is disclosed. Each communication interface has an active power mode and an inactive power mode. In the method, a communication service level is assessed for an active first communication interface. A second communication interface is activated and a communication service level is assessed for the activated second communication interface. A comparison is performed of the communication service levels of the first and second communication interfaces. If the second communication interface can provide a greater communication service level, then the first communication interface is deactivated by changing the first communication interface from the active power mode to the inactive power mode, and a communication service is provided through the second communication interface. Otherwise, a communication service is continued through the first communication interface.
