Electronic Device Big-Data Neighbor Cell Scanning for RAN Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices do not effectively utilize network-provided neighbor cell information for radio access network operations, limiting their ability to perform efficient cell reselection and handover processes.
Innovation Solution
The electronic device transmits information about a first cell to a server, receives neighbor cell information based on this data, identifies stored cell information, and performs scans using both sets of data to enhance RAN operations, including cell reselection and handover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic devices perform comprehensive cell scans to ensure reliable network connectivity, then network reliability is improved, but scanning time and energy consumption increase
Solution Approach 1:
The server performs preliminary processing of measurement results from multiple electronic devices to generate neighbor cell information in advance. This pre-computed information is then provided to electronic devices, allowing them to perform scans more efficiently without needing to conduct comprehensive scans from scratch, thus reducing scan time while maintaining reliability.
Solution Approach 2:
A server acts as an intermediary between electronic devices and the network. The server collects measurement results from multiple devices, processes this big data, and generates neighbor cell information that is then shared with electronic devices. This intermediary approach enables devices to leverage collective intelligence without each device performing redundant comprehensive scans.
2Productivity
If electronic devices collect and process comprehensive neighbor cell information from multiple sources, then cell reselection and handover operations are improved, but device complexity increases
Solution Approach 1:
The server serves as an intermediary that handles the complex collection, aggregation, and processing of measurement results from multiple electronic devices. It generates standardized neighbor cell information that is then provided to individual devices, reducing the complexity burden on each device while maintaining high productivity in cell reselection and handover operations.
Solution Approach 2:
The system segments the information processing task between the server (which handles big data collection and processing) and electronic devices (which handle local application of the information). This segmentation allows devices to benefit from comprehensive neighbor cell information without needing to implement complex processing capabilities themselves.
3Productivity
If electronic devices use conventional network information for RAN operations, then device simplicity is maintained, but RAN operation efficiency is limited
Solution Approach 1:
The server acts as an intermediary that processes big data from multiple electronic devices and generates optimized neighbor cell information. This pre-processed information is then provided to electronic devices, enabling them to perform RAN operations more efficiently without needing to implement complex data processing capabilities themselves.
Solution Approach 2:
Instead of each electronic device independently collecting and processing comprehensive measurement data, the system creates a copy of the processed neighbor cell information from the server. This allows devices to access optimized information without duplicating the complex processing functions, thereby improving RAN operation efficiency while maintaining device simplicity.
