Solution Overview
Problem
Some terminals are unable to perform GNSS measurements in a connected state, leading to challenges in accurately sending GNSS measurement time information to the network.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal sends GNSS measurement time information to the network, then the network can configure suitable measurement gaps, but the terminal must support GNSS measurement in connected state which increases device complexity
Solution Approach 1:
The patent introduces a capability indication parameter that changes the operational mode of the terminal. By indicating whether the terminal supports GNSS measurement in connected state, the system dynamically adjusts the measurement configuration parameters, allowing the network to send appropriate configuration information only when the terminal capability matches, thus resolving the contradiction between measurement accuracy and device complexity
Solution Approach 2:
The patent segments the GNSS measurement process into two distinct paths: one for terminals that support connected-state measurement and another for those that don't. This segmentation allows the system to handle different terminal capabilities separately, providing accurate measurement configuration to capable terminals while avoiding unnecessary complexity for incapable terminals
2Measurement precision
If the network sends configuration information to support GNSS measurement in connected state, then measurement accuracy improves, but power consumption increases
Solution Approach 1:
The patent implements a dynamic capability indication mechanism where the terminal's GNSS measurement capability status is explicitly signaled to the network. This dynamic approach allows the system to activate power-intensive connected-state measurement configurations only when the terminal indicates support for such mode, thereby improving measurement accuracy only when necessary and avoiding unnecessary power consumption
3Adaptability or versatility
If the terminal indicates capability to perform GNSS measurement in connected state, then the network can adapt configurations, but communication overhead increases
Solution Approach 1:
The patent extracts the essential capability indication from the complex GNSS measurement configuration process. By separating the capability indication step from the detailed configuration exchange, the system enables network adaptability through a minimal overhead signal, avoiding the need for extensive communication while still allowing the network to adjust configurations appropriately
