Wake-Up Message Carrying Terminal ID for Power Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for waking up terminal devices from deep sleep using low power waking up radio (LP-WUR) are inefficient, as the wake-up message is primarily used to wake up the primary circuit without fully utilizing its potential for information transmission.
Innovation Solution
A method that involves receiving a wake-up message and determining first identification information, which is all or part of the terminal identification information, to effectively utilize the wake-up message for information transmission, thereby optimizing power consumption and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the wake-up message is used only to wake up the primary circuit, then the standby power consumption is reduced effectively, but the information transmission efficiency is insufficient
Solution Approach 1:
The wake-up message is designed to serve dual functions: it not only wakes up the terminal device from deep sleep but also carries identification information for paging determination. This multi-functionality allows the single message to replace what would traditionally require separate signaling messages, thereby improving information transmission efficiency without increasing power consumption.
Solution Approach 2:
The patent combines the wake-up function and the paging indication function into a single wake-up message. The message structure integrates both the wake-up trigger and the terminal identification information, merging two previously separate communication purposes into one unified message format, which resolves the contradiction between power efficiency and information transmission efficiency.
2Productivity
If the wake-up message carries terminal identification information, then the information transmission efficiency is improved, but the message complexity increases
Solution Approach 1:
The terminal identification information is pre-configured and stored in the terminal device. When the wake-up message is received, the terminal device compares the identification information in the message with its pre-stored information to determine whether to wake up. This preliminary configuration approach simplifies the message structure while maintaining the ability to carry identification information, resolving the contradiction between information transmission efficiency and message complexity.
