Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In heterogeneous mobile communication networks, mobile terminals face challenges in efficiently selecting the best radio access while minimizing energy and processing resource consumption, especially when dealing with multiple radio access technologies and standards, leading to increased time and energy costs during scanning and handover processes.
Innovation Solution
A network entity is configured to obtain and correlate coverage and configuration information from multiple nodes, generating correlation information to determine overlap areas and assist mobile terminals in selecting the optimal radio access, using a coverage information database and inventory database to provide real-time updates and reduce scanning efforts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile terminals scan for all available radio accesses in heterogeneous networks, then the terminal can discover all potential radio access options, but the time and energy consumption increases drastically
Solution Approach 1:
The network entity performs preliminary actions by determining coverage areas for multiple nodes and identifying overlap areas before the mobile terminal needs to select a radio access. This pre-computed information is made available to the terminal, eliminating the need for exhaustive scanning and significantly reducing terminal energy consumption while maintaining comprehensive radio access discovery capability
Solution Approach 2:
A network entity acts as an intermediary between the network nodes and mobile terminals. This intermediary determines coverage areas, identifies overlap regions, and provides this processed information to terminals, thereby reducing the scanning burden on terminals while ensuring they can discover all available radio access options in heterogeneous networks
2Reliability
If mobile terminals perform inter-frequency measurements to find better radio access, then the terminal can improve service quality, but ongoing services are suspended for short periods
Solution Approach 1:
The network entity performs preliminary determination of coverage areas and overlap regions before the mobile terminal needs to handover. By providing this pre-computed information to the terminal, the terminal can make faster handover decisions without performing lengthy inter-frequency measurements, thus improving service quality while minimizing service interruption time
3Adaptability or versatility
If radio discovery process is performed in certain radio access technologies, then the terminal can discover available radio accesses, but random access resources of the network are consumed
Solution Approach 1:
The network entity serves as an intermediary that determines coverage areas and identifies overlap areas for multiple nodes. By providing this pre-computed information to mobile terminals, the network reduces the need for terminals to perform resource-intensive radio discovery processes, thereby maintaining comprehensive radio access discovery capability while significantly reducing consumption of random access resources
Solution Approach 2:
The network entity performs the resource-intensive coverage determination and overlap identification in advance, before terminals need to discover radio accesses. This pre-computed information is provided to terminals, eliminating the need for terminals to consume network random access resources during their own discovery processes
