Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user-plane positioning connection is implemented without defined message transmission methods, then positioning functionality is enabled, but communication performance deteriorates due to uncertainty in message transmission
Solution Approach 1:
The patent applies universality by enabling the user-plane positioning connection to utilize existing NAS message transmission mechanisms (service request messages and uplink/downlink non-access stratum transmission messages) that are already part of the 5G system. This allows the positioning functionality to leverage the established, reliable message transmission infrastructure rather than creating a separate protocol, thereby improving communication performance while avoiding additional complexity
Solution Approach 2:
The patent uses the NAS (Non-Access Stratum) message transmission mechanism as an intermediary to carry positioning-related information. By embedding positioning connection messages within existing NAS message structures (service request messages for uplink and downlink non-access stratum transmission messages for downlink), the system achieves reliable transmission without requiring a new dedicated message protocol
2Ease of operation
If existing NAS message structures are used for positioning connection messages, then message transmission becomes standardized, but message format complexity increases
Solution Approach 1:
The patent applies nesting by embedding positioning connection messages within existing NAS message structures. Specifically, positioning-related information is nested inside service request messages for uplink transmission and inside downlink non-access stratum transmission messages for downlink transmission. This nested structure allows the positioning functionality to utilize the already-standardized NAS message formats, making transmission easier while managing complexity through hierarchical organization
