Mobility State Reporting for Wireless User Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in heterogeneous networks, lack an effective mechanism to account for and report mobility information when a user device is out of service coverage, leading to inefficiencies in signaling overhead and UE power consumption, especially in scenarios with irregular traffic patterns.
Innovation Solution
The method involves a user device reporting mobility information to a network by indicating specific time periods or accumulated time spent out of service coverage, using identifiers within the mobility information to enhance reporting accuracy and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If mobility information is reported continuously without indicating out-of-coverage periods, then the network has complete mobility data, but signaling overhead increases and UE power consumption increases
Solution Approach 1:
The patent extracts and separates the out-of-coverage period indication from the continuous mobility information reporting. By identifying and removing the redundant reporting during out-of-coverage periods, the solution reduces signaling overhead and UE power consumption while preserving essential mobility data through selective reporting of only in-coverage periods.
Solution Approach 2:
Instead of reporting mobility information continuously (excessive action), the patent applies partial action by reporting only during in-coverage periods. This selective reporting provides sufficient mobility information for network decisions while significantly reducing the frequency and volume of reports, thereby lowering energy consumption and signaling overhead.
2Measurement precision
If mobility information is reported frequently, then connection management decisions are more accurate, but signaling overhead increases
Solution Approach 1:
The patent extracts the out-of-coverage indication from the mobility reporting process, allowing the network to identify periods where reporting should be suspended. This separation enables more accurate mobility reporting during relevant periods while eliminating redundant signaling during out-of-coverage periods.
Solution Approach 2:
The patent implements partial reporting by transmitting mobility information only during in-coverage periods rather than continuously. This provides sufficiently accurate mobility data for connection management decisions while proportionally reducing the total quantity of signaling messages.
3Loss of information
If the UE reports all mobility periods including out-of-coverage time, then the network has complete mobility history, but the processing complexity increases
Solution Approach 1:
The patent extracts out-of-coverage period indications from the mobility history data, allowing the network to separately identify and handle relevant reporting periods. This simplifies network processing by automatically filtering out periods where the UE was not available for communication, reducing the complexity of mobility history analysis.
Solution Approach 2:
The patent applies partial reporting by providing mobility history for only in-coverage periods rather than all periods. This gives the network sufficient mobility information for decision-making while reducing the total volume of data that requires processing and analysis.

AI summary
Methods, apparatuses, and computer program product for an optimized procedure, signaling, and configuration for the reporting of a mobility state estimate (MSE) and/or mobility history information are provided. One method may include reporting, by a user device, mobility information to an associated network, and indicating one or more time periods during which the user device has been out of service coverage of the network.
