Solution Overview

Problem

Conventional techniques for controlling modem operation modes in mobile terminals require dedicated signaling, leading to increased network loads and limited versatility in power management, especially when applications continue to operate in the background, reducing battery life without significant user benefit.

Innovation Solution

Implementing event-triggered mode switching for mobile terminals, which selects from a plurality of modes based on static or network-configured constraints, allowing the wireless network to control mode changes without dedicated signaling, thereby reducing power consumption and network loads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dedicated signaling is used to control modem operation modes, then network control over mode switching is improved, but network load increases

Engineering Contradiction:

Improvenetwork controlVSAvoidnetwork load

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The mobile terminal autonomously selects and switches between modem operation modes based on pre-configured constraints and current operational conditions, without requiring real-time dedicated signaling from the network. The terminal serves itself by making mode selection decisions locally, reducing network control overhead while maintaining acceptable network oversight through constraint configuration.

Inventive Principle:

Principle #25Self-service

2Device complexity

If pre-defined fixed transitions between operating states are used, then device complexity is reduced, but adaptability to different conditions is limited

Engineering Contradiction:

Improvecontrol mechanismVSAvoidmode selection flexibility

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The mode selection mechanism transitions from static pre-defined transitions to dynamic event-triggered switching. The terminal evaluates current operational conditions (such as data activity, screen state, application background operations) and dynamically selects appropriate modem modes based on pre-configured constraints, enabling flexible adaptation to varying conditions while maintaining manageable complexity through constraint-based decision logic.

Inventive Principle:

Principle #15Dynamics

3Reliability

If the modem remains in high-power modes to support continuous application operation, then application functionality is maintained, but power consumption increases

Engineering Contradiction:

Improveapplication continuityVSAvoidbattery consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system changes the operational parameters of the modem by switching between different power modes (high-power and low-power states) based on actual application needs and trigger events. When applications are running in the background without user interaction, the modem transitions to lower power modes, dynamically adjusting power consumption parameters while maintaining application functionality through event-triggered wake-up capabilities.

AI summary

A mobile terminal comprises a modem for communication with a wireless network. The modem is configured for operating in a plurality of different modes. The mobile terminal comprises a processing device operative to, in response to detecting a trigger event, perform a mode selection to select a mode from the plurality of modes in accordance with at least one constraint, and control the modem to start operating in the selected mode.
