Mobile Device Channel Prediction for Seamless Cell Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in spectrum usage due to the need for frequent channel availability queries by mobile devices as they move between cells, leading to increased power consumption, bandwidth usage, and interruptions in service.
Innovation Solution
An apparatus that receives predicted geographic path signaling from a mobile device and determines available radio channels along the path, providing an advance indication of channel availability to minimize channel switches and optimize power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mobile devices frequently query channel availability when moving between cells, then channel selection accuracy is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary channel availability queries before the mobile device actually moves into new cells. By predicting the geographic path and querying channels in advance for upcoming cells, the device can prepare channel switching without urgent queries during movement, reducing the frequency and power consumption of queries while maintaining accurate channel selection.
2Reliability
If mobile devices frequently query channel availability when moving between cells, then channel availability is ensured, but service interruptions increase
Solution Approach 1:
The system performs preliminary channel availability queries and determines suitable channels before the mobile device enters new cells. This advance preparation allows the device to switch channels seamlessly without service interruptions during cell transitions, as the target channel is already identified and ready for immediate use.
Solution Approach 2:
The system dynamically adjusts the channel querying strategy based on the predicted geographic path and actual device movement. By continuously updating the predicted path and adjusting which cells to query in advance, the system optimizes the balance between ensuring channel availability and minimizing service interruptions.
3Measurement precision
If mobile devices frequently query channel availability when moving between cells, then channel selection accuracy is improved, but bandwidth usage increases
Solution Approach 1:
The system performs preliminary channel availability queries for predicted geographic paths before the device actually needs to move into those cells. This batching of queries in advance reduces the total number of frequent queries during movement, thereby reducing bandwidth consumption while still maintaining accurate channel selection through pre-obtained channel availability information.

AI summary
This document describes an apparatus for providing an advance indication of channels available for use by a mobile device travelling along a geographic path. The path extends across two or more cells, with each cell defining a particular set of radio channels available for use by the mobile device in that cell. The apparatus is configured to receive predicted geographic path signalling associated with prediction of the geographic path to be taken by the mobile device. The apparatus is also configured to determine radio channels available for use by the mobile device along that path. The apparatus is also configured to provide, in advance, an indication of the radio channels available for use by the mobile device along the geographic path in each respective cell along the path.
