SLPP Session Identifier for Accurate Sidelink Initiator Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sidelink positioning protocols struggle to accurately identify the initiator of a session when multiple user equipment (UE) participants are involved, leading to ambiguity and reduced positioning accuracy.
Innovation Solution
The implementation of a sidelink positioning protocol (SLPP) message that includes a first session identifier to uniquely identify the session initiator, allowing for clear distinction among participants, thereby enhancing the accuracy of information interaction and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple user equipment participants are involved in a sidelink positioning session, then the positioning capability is enhanced, but the ability to accurately identify the session initiator deteriorates due to ambiguity
Solution Approach 1:
The session identifier is segmented into multiple components: a session management portion for managing the positioning session and an initiator identification portion for identifying the session initiator. This segmentation allows the system to maintain both multi-participant positioning capability and accurate initiator identification by assigning different functional segments to different purposes within the same message structure.
2Reliability
If a session identifier is included in SLPP messages, then the session management is improved, but the message complexity increases
Solution Approach 1:
The session identifier is designed with multi-functionality to serve both session management and initiator identification purposes simultaneously. By embedding multiple pieces of information within a single session identifier field, the patent reduces the need for separate message elements, thereby improving session management reliability while minimizing the increase in message complexity.
