Modem Traffic-Based CDRX Cycle Adjustment

Solution Overview

Problem

Existing power consumption control methods for user equipment in connected mode are inefficient, as they either require synchronous upgrades with base stations, leading to high costs and potential personal information leakage, or rely on inaccurate application traffic information for CDRX cycle parameter generation, resulting in poor power consumption control.

Innovation Solution

A method where the baseband processor in user equipment obtains modem traffic information to send indication signals to the base station, allowing it to adjust the CDRX cycle, thereby reducing power consumption and ensuring better communication performance without needing the application processor to be awake.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the AP detects service status information and transmits it to the modem and base station for CDRX cycle parameter generation, then power consumption control is implemented, but personal information leakage risk increases and system complexity increases

Engineering Contradiction:

Improvepower consumptionVSAvoidpersonal information leakage

Core Design Contradiction:

Use of energy by moving objectVSLoss of information

Solution Approach 1:

The patent segments the power consumption control function by having the modem independently detect service status information and generate CDRX cycle parameters without requiring the AP to process or transmit personal information. This segmentation isolates the sensitive information handling to the modem only, reducing information leakage risk while maintaining power consumption control capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The modem performs self-service by independently detecting service status information and generating CDRX cycle parameters without external intervention from the AP or base station. This self-service approach eliminates the need for the AP to handle sensitive information, thereby reducing personal information leakage risk while achieving power consumption control.

Inventive Principle:

Principle #25Self-service

2Use of energy by moving object

If the AP generates the new CDRX cycle parameter based on application traffic information, then power consumption control is implemented, but accuracy of the CDRX cycle parameter decreases

Engineering Contradiction:
