Core Network Positioning Message Timing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, the core network device often fails to complete positioning preparation works within a prescribed time due to uncontrolled timing for each stage of the positioning process, leading to positioning delays.
Innovation Solution
A positioning method where the core network device sends a positioning message with time information to indicate when response information should be returned, ensuring that both access network devices and terminal devices respond within the specified time, thereby controlling the timing of each stage in the positioning process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the core network device does not control the timing for each stage of positioning, then the positioning process is simple and flexible, but the positioning preparation work cannot be completed within the prescribed time
Solution Approach 1:
The core network device performs preliminary actions by determining time information for each positioning stage in advance and including it in the positioning message. This allows the access network device and terminal device to know exactly when to complete each task, ensuring positioning preparation is finished within the prescribed time without adding complex real-time control mechanisms.
2Productivity
If the core network device controls the timing of each positioning stage, then the positioning preparation work can be completed within prescribed time, but the positioning process becomes more complex
Solution Approach 1:
The patent uses an intermediary approach by embedding time information within the existing positioning message structure. The core network device includes time information in the positioning message sent to the access network device, which then forwards it to the terminal device. This intermediary message structure allows timing control without requiring complex dedicated control systems, thus improving productivity while limiting complexity increase.
