Paging Response Delay for Terminal Power Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication systems, terminal devices consume excessive power when responding to paging messages due to poor link quality, leading to increased power consumption.
Innovation Solution
A paging method that allows terminal devices to delay responding to paging messages until link quality improves, using indication information in the paging message to determine an appropriate delay time, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the terminal device immediately responds to the paging message, then the response time is reduced, but the power consumption increases due to higher transmission power needed for poor link quality
Solution Approach 1:
The terminal device dynamically adjusts the response timing based on real-time link quality assessment. When link quality is poor, the device delays the paging response transmission until link quality improves, thereby reducing the required transmission power while still maintaining acceptable response times. This dynamic adaptation resolves the contradiction between fast response and low power consumption.
Solution Approach 2:
The invention changes the timing parameter of the paging response based on link quality conditions. By introducing a delay mechanism that adjusts the response time parameter according to channel conditions, the system achieves lower transmission power requirements without completely sacrificing response speed, thus resolving the contradiction between response time and power consumption.
2Reliability
If the terminal device uses higher power to respond to paging messages, then the communication reliability is improved, but the power consumption increases
Solution Approach 1:
The terminal device dynamically adapts its transmission strategy by monitoring link quality and adjusting the response timing accordingly. When link quality is poor, the device waits for conditions to improve before transmitting the paging response, thereby achieving reliable communication at lower power levels. This dynamic approach maintains communication reliability while reducing power consumption compared to always using high power.
Solution Approach 2:
The invention converts the harmful effect of poor link quality (which would normally require high power for reliable transmission) into a beneficial delay opportunity. By waiting for link quality to improve naturally, the system achieves reliable communication without the need for high power transmission, thus converting the harmful condition into a power-saving opportunity.
3Use of energy by moving object
If the terminal device delays the paging response, then the power consumption is reduced, but the response time increases
Solution Approach 1:
The invention changes the response time parameter dynamically based on link quality conditions. Instead of using a fixed immediate response or a long fixed delay, the system adjusts the response timing parameter adaptively - using short delays when link quality is already acceptable and longer delays only when necessary to achieve power savings, thus balancing response time and power consumption.
Solution Approach 2:
The terminal device applies a partial delay action rather than immediate response only when link quality conditions warrant it. The delay is applied selectively and partially - not always, and not indefinitely - but only to the extent necessary to improve power efficiency while keeping the additional response time acceptable. This partial action resolves the contradiction by avoiding excessive delay while still achieving power savings.

AI summary
Disclosed are a paging method and device. The method includes that: a terminal device receives a paging message transmitted by an access network device, wherein the paging message includes first indication information, and the first indication information is used to indicate that delay in return of a paging response message is allowed; and the terminal device determines whether to delay returning the paging response message according to a current link status.
