Dynamic Location Update Period Adjustment in M2M Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current M2M systems lack a detailed procedure for flexibly using and identifying device location information and face inefficiencies due to fixed location update periods, leading to increased data loads and power consumption, especially in environments with variable device speeds and mobility.
Innovation Solution
A method and apparatus that dynamically change the location update period based on received location information and device state information, allowing the common service entity to adjust the update period without user intervention, using location policy resources and network service entities to optimize location information acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a fixed location update period is used in M2M systems, then the system provides consistent location information acquisition, but unnecessary data loads and power consumption increase
Solution Approach 1:
The patent implements dynamic adjustment of the location update period based on device mobility states. The common service entity monitors device movement characteristics and automatically modifies the update period parameter, transitioning from a static fixed period to a dynamic adaptive period that responds to real-time device conditions, thereby reducing unnecessary updates for stationary or slow-moving devices
Solution Approach 2:
The patent changes the location update period parameter according to device state information. By analyzing device mobility patterns and adjusting the update period parameter accordingly (shorter period for moving devices, longer period for stationary devices), the system optimizes power consumption and data load while maintaining appropriate location information freshness
2Measurement precision
If location information is updated frequently, then location accuracy is improved, but data load increases
Solution Approach 1:
The patent applies partial action by updating location information only when necessary based on device mobility state. Instead of continuous frequent updates for all devices, the system selectively updates location information at appropriate intervals, performing exactly the amount of action needed to maintain location accuracy without excessive updates that would increase data load
3Adaptability or versatility
If a fixed update period is used, then system complexity is reduced, but the system cannot adapt to variable device speeds and mobility
Solution Approach 1:
The patent implements self-service through automatic mobility-based update period adjustment. The common service entity autonomously monitors device state information, determines mobility patterns, and adjusts the location update period without requiring manual configuration or complex external control systems, thereby achieving adaptability while keeping the control mechanism relatively simple
