Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the terminal uses internal circuit design optimization to reduce power consumption, then power consumption is reduced, but communication behaviors controlled by the network side continue to cause energy waste

Engineering Contradiction:
Improveterminal power consumptionVSAvoidcommunication behavior adaptability
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent makes the terminal's communication behavior dynamic by allowing it to adaptively adjust its communication activities based on network conditions and power state. The terminal can dynamically control paging reception, scheduling request transmission, and data transmission timing, transforming from a passive network-controlled device to an active power-managing entity that balances communication needs with power consumption requirements

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes key communication parameters including paging cycle length, scheduling request interval, and data transmission timing. By adjusting these parameters based on power consumption requests and network conditions, the system optimizes the balance between communication effectiveness and power consumption, allowing terminals to extend battery life while maintaining essential connectivity

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the terminal frequently communicates with the network side, then communication performance is improved, but power consumption increases

Engineering Contradiction:
Improvecommunication performanceVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic communication actions where the terminal receives pages at configured intervals, transmits scheduling requests periodically when needed, and sends data at scheduled times. This periodic structure allows the terminal to enter low-power states between communication events while maintaining network connectivity, reducing average power consumption while preserving communication performance

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The terminal autonomously manages its own power consumption by selecting power saving modes, configuring communication parameters, and controlling its own transmission/reception activities based on buffer status and power requirements. This self-service capability eliminates the need for continuous network control signals, reducing overhead and power consumption

Inventive Principle:
Principle #25Self-service

3Device complexity

If the network side controls communication behaviors, then network management is simplified, but terminal power consumption cannot be optimized

Engineering Contradiction:
Improvenetwork management complexityVSAvoidterminal power consumption
Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

The terminal sends power saving mode requests and buffer status information to the network in advance, allowing the network to pre-configure appropriate communication parameters before actual data transmission is needed. This preliminary action enables the network to prepare scheduling decisions and paging configurations that optimize power consumption without requiring complex real-time control mechanisms

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The terminal provides feedback to the network about its power consumption status, buffer conditions, and communication needs. The network uses this feedback to adjust paging cycles, scheduling intervals, and transmission parameters, creating a closed-loop system that continuously optimizes power consumption while maintaining network management simplicity

Inventive Principle:
Principle #23Feedback

AI summary

A method and a device for providing low power consumption services and a communication system are provided in the embodiments of the present invention. The method includes: receiving a low power consumption request sent by a terminal; when determining that the low power consumption request is supported, sending a first configuration parameter indicating that the low power consumption request is supported to a base station, so that the base station performs low power consumption communication with the terminal according to the first configuration parameter; and sending acknowledgement information indicating that the low power consumption request is supported to the terminal, in which the acknowledgement information carries a second configuration parameter, so that the terminal performs low power consumption communication with the base station according to the second configuration parameter. In this way, a network side provides services with different power consumption for different terminals according to requirements of terminals.
