Wireless Positioning Energy Savings via Priority-Based Resource Allocation

The patent changes the parameters of location service requests by introducing priority levels (high, medium, low) and service types (mandatory, optional, provisional). This allows the network to differentiate between critical positioning needs and non-critical ones, enabling selective activation of base stations based on request characteristics rather than uniformly serving all requests, thus reducing overall energy consumption while maintaining service availability for essential cases.

The patent implements dynamic base station activation where base stations transition between low-energy and active states based on incoming location service requests. The network dynamically decides which base stations to wake up based on request priority and current network conditions, creating a flexible system that adapts energy consumption to actual service needs rather than maintaining all base stations in active state continuously.

The patent applies different service quality levels to different location requests based on their priority and requirements. High-priority mandatory requests receive full positioning accuracy with all necessary base stations activated, while medium-priority optional requests receive reduced accuracy with fewer base stations, and low-priority provisional requests receive minimal service. This local differentiation ensures energy is not wasted on high-accuracy positioning when only low-accuracy is needed.

The patent implements partial action by activating only the necessary subset of base stations required to meet the positioning accuracy requirements of each request. Instead of activating all base stations to ensure maximum accuracy, the system calculates the minimum required base station activation based on request priority and accuracy requirements, avoiding excessive energy consumption while still achieving adequate positioning accuracy for each specific case.
