Paging Group Determination for Inactive Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, there is a challenge in accurately determining the paging group information for terminal devices in inactive states, leading to potential paging failures and increased power consumption, as access network devices may mistakenly use idle state paging group information when the terminal device is inactive.
Innovation Solution
The method involves the access network device receiving paging assistance information from the core network device to determine the appropriate first paging group information for terminal devices in inactive states, ensuring consistent understanding and reducing the likelihood of paging failures and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the access network device uses idle state paging group information for inactive state terminal devices, then the device complexity is reduced, but the reliability of paging deteriorates due to potential paging failures
Solution Approach 1:
The patent segments the paging group information into two distinct types: idle state paging group information and inactive state paging group information. The access network device is configured to use different paging group information based on the terminal device's state, ensuring that inactive state terminals receive paging messages from the correct group, thereby resolving the reliability issue without requiring complex state detection mechanisms.
Solution Approach 2:
The access network device receives and stores inactive state paging group information in advance from the core network device. This preliminary configuration ensures that when a terminal device transitions to inactive state, the access network device can immediately use the pre-configured correct paging group information without needing to perform complex real-time state determination, thus improving reliability while maintaining simplicity.
2Productivity
If the access network device determines paging group information independently without core network assistance, then the communication efficiency is improved, but the measurement precision of terminal state deteriorates leading to incorrect paging group selection
Solution Approach 1:
The core network device acts as an intermediary that provides the access network device with accurate inactive state paging group information. This intermediary mechanism ensures that the access network device uses precisely determined paging group information corresponding to the terminal's actual state, eliminating measurement precision errors while maintaining communication efficiency through streamlined paging procedures.
3Ease of operation
If the access network device uses incorrect paging group information for inactive state terminals, then the ease of operation is maintained, but the loss of information increases due to paging failures
Solution Approach 1:
The access network device receives and stores inactive state paging group information in advance from the core network device. This preliminary configuration ensures that when a terminal device transitions to inactive state, the access network device can immediately use the pre-configured correct paging group information without needing to perform complex real-time state determination, thus improving reliability while maintaining simplicity.
