Terminal Positioning Offload for Network Server Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face data congestion due to the excessive volume of positioning data generated when a large number of terminal devices connect to the network, overwhelming the location server's processing capacity.
Innovation Solution
Terminal devices participate in the positioning process by receiving information from network devices and performing initial position calculations using a Lagrange operator product algorithm, alleviating the computational burden on the location server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the location server processes all positioning data from a large number of terminal devices, then positioning accuracy can be maintained, but data congestion occurs and the server becomes overwhelmed
Solution Approach 1:
The patent segments the positioning data processing task by dividing terminal devices into multiple groups, where each group is handled by a different network device. This distributes the computational load from a single location server across multiple network devices, preventing data congestion while maintaining positioning accuracy through coordinated processing of all groups.
2Adaptability or versatility
If the location server processes positioning data for all terminal devices, then comprehensive positioning coverage is achieved, but the volume of positioning data exceeds the server's processing threshold
Solution Approach 1:
The patent divides the network into multiple regions with different network devices serving as positioning nodes for different groups of terminal devices. This segmentation allows comprehensive positioning coverage across the entire network while each network device processes only a manageable subset of positioning data, preventing any single server from being overwhelmed by excessive data volume.
3Stability of the object's composition
If centralized positioning processing is used at the location server, then positioning consistency is maintained, but system robustness decreases when the server becomes congested
Solution Approach 1:
The patent creates a distributed positioning architecture where multiple network devices can independently perform positioning calculations for their respective terminal device groups. This segmentation enhances system robustness by eliminating single points of failure, while positioning consistency is maintained through standardized processing procedures and coordination mechanisms across all network devices.
Solution Approach 2:
The patent changes the architectural parameter from centralized to distributed processing, allowing the system to adapt to varying load conditions. When the location server becomes congested, positioning functions can be executed by multiple network devices simultaneously, maintaining system reliability while preserving positioning consistency through coordinated parameter management across the distributed network.
