Mobile Device Network Search via Preprogrammed MCC Indices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network access for mobile devices is inefficient when roaming, as devices are limited to searching within their registered Mobile Country Code (MCC), leading to time-consuming searches and inefficient use of resources, especially when higher preferred networks are available in neighboring countries.
Innovation Solution
A mobile communication device is preprogrammed with intermediate parameters, such as indices linking MCCs of the registered country and neighboring countries, allowing it to search for reachable networks based on geographical contiguity, usage history, or user preference, thereby streamlining the search process and reducing battery drain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the mobile device is restricted to search only within the registered MCC, then the search process is simplified and device complexity is reduced, but the network search time increases and the device cannot access higher preferred networks in neighboring countries
Solution Approach 1:
The mobile device is preprogrammed with intermediate parameters (indices) that link the registered MCC to neighboring countries' MCCs. This preliminary configuration enables the device to efficiently search for reachable networks in neighboring countries without performing exhaustive searches, thus reducing network search time while maintaining a simplified search process.
2Reliability
If the mobile device performs exhaustive network searching across all available networks, then the device can find reachable networks, but over-the-air resources are wasted and battery power is drained
Solution Approach 1:
The invention extracts and utilizes preprogrammed intermediate parameters (indices) from the device's memory to guide the network search process. By extracting only the necessary MCC information linked through indices rather than performing exhaustive searches across all networks, the device achieves reliable network access while minimizing battery power consumption and preserving over-the-air resources.
3Reliability
If the mobile device performs exhaustive network searching, then network access reliability is improved, but over-the-air resources are inefficiently used
Solution Approach 1:
The mobile device is preprogrammed with intermediate parameters (indices) that link the registered MCC to neighboring countries' MCCs. This preliminary configuration enables the device to efficiently search for reachable networks in neighboring countries without performing exhaustive searches, thus reducing network search time while maintaining a simplified search process.

AI summary
A mobile communication device prior to establishing a communication session needs first to connect to a reachable network. To facilitate the search for the reachable network, the mobile communication device is preprogrammed intermediate parameters which lead to a plurality of reachable networks that are preselected based on a predetermined criterion.
