Engineering Contradiction Analysis
1Use of energy by moving object
If all terminal devices in a cell use LP-WUS paging mode, then energy saving for terminal devices is improved, but network load and spectrum utilization efficiency deteriorate
Solution Approach 1:
The patent applies local quality by allowing different terminal devices within the same cell to use different paging modes based on their specific conditions. The network device determines a first condition for terminal devices to meet in order to use LP-WUS paging mode, enabling only eligible devices to use this energy-saving mode while others continue with traditional paging, thus balancing energy saving with network load management
Solution Approach 2:
The patent implements dynamics by making the paging mode selection flexible and adaptive rather than fixed. The network device can dynamically determine which terminal devices meet the first condition for LP-WUS paging mode based on current network status and device characteristics, allowing the system to adapt to changing conditions and optimize both energy saving and network performance
2Productivity
If traditional paging mode is used for all terminal devices, then spectrum utilization efficiency is maintained, but energy consumption of terminal devices increases
Solution Approach 1:
The patent enables selective application of LP-WUS paging mode to specific terminal devices that meet certain conditions, rather than universally applying one paging mode. This allows the network to maintain traditional paging for devices where it ensures optimal spectrum utilization while enabling energy-saving mode for eligible devices
3Use of energy by moving object
If LP-WUS paging mode is configured for the entire cell, then terminal device energy saving is improved, but device complexity and configuration flexibility worsen
Solution Approach 1:
The patent applies preliminary action by having the network device pre-determine and notify terminal devices of the first condition required for LP-WUS paging mode usage. This advance notification allows terminal devices to understand the requirements before attempting to use the energy-saving mode, reducing configuration complexity and improving flexibility

AI summary
This application provides a communication method, apparatus, and system, and is applied to the field of communication technologies. The communication method provided in this application includes: determining a first condition that a terminal device supporting a low power wake-up receiver LP-WUS paging mode in a first cell needs to meet to perform the LP-WUS paging mode; and sending first indication information to the terminal device, where the first indication information indicates the first condition. Based on the communication method provided in this application, a network device may indicate, to the terminal device, the first condition that the terminal device supporting the LP-WUS paging mode in the first cell needs to meet to perform the LP-WUS paging mode, to avoid that all terminal devices supporting the LP-WUS paging mode in the first cell perform the LP-WUS paging mode or none of the terminal devices performs the LP-WUS paging mode, thereby meeting a requirement of the terminal device for low power consumption as far as possible without reducing performance of a network side.
