UE Environmental Status Information for Mobility Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face challenges in managing mobility and offloading decisions due to inadequate characterization of UE mobility status, leading to inefficient use of network resources and potential connection interruptions, especially in heterogeneous networks with varying signal power and interference.
Innovation Solution
UEs provide environmental status information (ESI) based on non-RF sensor data, which is used by the network to optimize connection management, including offloading decisions and handover strategies, thereby improving resource allocation and mobility handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional RF-based mobility management is used, then network coverage is maintained, but mobility characterization precision is insufficient leading to inefficient resource allocation
Solution Approach 1:
The patent introduces environmental status information (ESI) from non-RF sensors as an intermediary to bridge the gap between RF-based network management and actual UE mobility status. These sensors (accelerometers, gyroscopes, barometers, GPS) provide independent mobility characterization that complements traditional RF measurements, enabling more accurate handover and offloading decisions without relying solely on signal strength metrics.
Solution Approach 2:
The patent replaces purely RF-based mobility detection with a hybrid approach incorporating mechanical sensors. Instead of relying only on electromagnetic signal variations, the system uses mechanical sensors (accelerometers, gyroscopes) to directly measure physical motion characteristics, providing more reliable mobility status information especially in RF-challenging environments.
2Productivity
If heterogeneous networks with multiple access points are deployed, then network capacity increases, but interference and connection stability issues worsen
Solution Approach 1:
The patent implements feedback mechanisms where UEs continuously report environmental status information to the network, and the network adjusts handover and offloading decisions based on this feedback. The system monitors sensor data trends over time and dynamically adapts connection management parameters, creating a closed-loop control system that maintains connection stability in heterogeneous networks.
Solution Approach 2:
The patent performs preliminary mobility assessment using environmental status information before executing handover or offloading decisions. By analyzing sensor data trends and predicting future mobility patterns, the system prepares appropriate connection management actions in advance, preventing connection interruptions and improving handover success rates in heterogeneous network environments.
Data Source
AI summary
User equipment (UE) connection handling is disclosed in which UE environmental status information is used at a network entity to make informed decisions regarding mobility handling and data offloading. A UE determines its environmental status information based on input from at least one non-RF sensor located in the UE. The UE generates and then transmits a control message comprising the UE environmental status information to a network entity in communication with the UE. The network entity receives the control message and uses the UE environmental status information to manage a connection of the associated UE based at least in part on the UE environmental status information.
