5G Handover Positioning Capability Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G communication systems face challenges in efficiently managing positioning capability information for handover processes between base stations, leading to suboptimal network performance and user experience.
Innovation Solution
A method where a first base station receives positioning capability information from a second base station and a measurement report from a wireless device, then sends a handover request message to the second base station based on this information, facilitating a seamless handover process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning capability information is exchanged between base stations during handover, then positioning accuracy is improved, but signaling overhead and network complexity increase
Solution Approach 1:
The patent extracts positioning capability information from the target base station and transmits it to the source base station via a message container. This allows the source base station to make informed handover decisions based on the target's positioning capabilities, improving positioning accuracy without requiring complex direct communication between all network elements.
Solution Approach 2:
The patent introduces an intermediary message structure (handover request message containing positioning capability information) that mediates between the target base station and source base station. This intermediary mechanism simplifies the interaction protocol while enabling accurate positioning capability assessment during handover.
2Productivity
If positioning capability information is obtained before handover, then handover performance is improved, but information acquisition time increases
Solution Approach 1:
The patent obtains positioning capability information from the target base station before the actual handover execution. By performing this information acquisition in advance during the handover preparation phase, the system ensures that positioning capabilities are known prior to handover, improving handover performance without adding significant delay since the information is retrieved as part of the existing handover signaling sequence.

AI summary
A first base station receives, from one or more network elements, positioning capability information of a second base station. The first base station receives, from a wireless device, a measurement report. The first base station sends a message for handing over to the second base station. The sending is based on the measurement report. The sending is based on the positioning capability information of the second base station.
