Core Network Delay Signaling for Terminal-Side Measurement Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies fail to accurately determine the delay information between a terminal device and an access network device due to the lack of support for terminal-side delay measurement in some devices, leading to incomplete understanding by core networks.
Innovation Solution
An information transmission method where an access network device receives delay measurement information from a core network device, determines if the terminal device supports terminal-side delay measurement, and sends indication information to the core network, allowing for accurate determination of terminal-side delay inclusion or support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the access network device provides delay information to the core network device, then the core network can obtain delay information, but the core network cannot determine the specific meaning of the delay information without indication information
Solution Approach 1:
The patent introduces indication information as an intermediary element that mediates between the delay information and the core network device. This indication information carries metadata about the delay information (such as whether it includes terminal-side delay or air interface delay), enabling the core network to correctly interpret the delay information without requiring complex negotiation or additional signaling protocols.
2Measurement precision
If the terminal device supports terminal-side delay measurement, then accurate delay information can be obtained, but not all terminal devices support this measurement capability
Solution Approach 1:
The patent applies local quality by differentiating the delay measurement capability at the terminal device level. The system accepts that different terminals have different measurement capabilities (some support terminal-side delay measurement, others don't) and designs the indication information to reflect these local differences. This allows the core network to adapt its interpretation of delay information based on the specific terminal's capabilities rather than requiring uniform capability across all devices.
3Loss of information
If the access network device always includes terminal-side delay in delay information, then comprehensive delay data is provided, but devices without measurement capability cannot provide accurate terminal-side delay
Solution Approach 1:
The patent implements dynamics by making the delay information structure adaptive rather than fixed. The indication information dynamically indicates what types of delay are included in each delay information report (terminal-side delay, air interface delay, or neither). This allows the content of delay information to change based on the terminal's actual measurement capabilities, ensuring that the system always requests and provides the most accurate delay data available for each specific terminal device.
