Subscription Switching Logic for Fallback Network Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunication terminals face issues with suboptimal Quality of Service, higher costs, and battery drain when operating on fallback subscriptions due to frequent network searches and lack of knowledge about optimal operational networks.
Innovation Solution
A telecommunication arrangement with a Profile Selection Agent (PSA) and Configuration Agent (PSCA) automatically switches the terminal to the best operational connectivity upon re-entering network coverage, minimizing battery consumption and remote communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the telecommunication terminal uses fallback subscription to maintain global coverage, then network availability is improved, but Quality of Service deteriorates and costs increase
Solution Approach 1:
The terminal performs preliminary actions by storing a list of operational networks with priority order before switching to fallback subscription. When fallback is activated, the terminal can quickly revert to operational networks by consulting this pre-stored list, avoiding the need to search for networks while on fallback, thus maintaining QoS without sacrificing availability.
2Adaptability or versatility
If the telecommunication terminal frequently searches for operational network coverage, then network selection capability is improved, but battery consumption increases
Solution Approach 1:
The terminal performs preliminary action by storing the list of operational networks with priority ordering before entering fallback mode. This pre-stored information eliminates the need for frequent network searching while on fallback subscription, significantly reducing battery consumption while maintaining the ability to quickly switch back to operational networks when available.
3Area of stationary object
If the telecommunication terminal operates on fallback subscription, then global coverage is maintained, but operational costs increase
Solution Approach 1:
The terminal performs preliminary action by storing the prioritized list of operational networks before switching to fallback. This enables the terminal to minimize fallback usage by quickly detecting when operational networks become available and switching back, thereby reducing expensive roaming charges while maintaining global coverage capability.
4Manufacturing precision
If the telecommunication terminal continuously attempts to select operational connectivity, then network optimization is improved, but service continuity deteriorates
Solution Approach 1:
Instead of continuous attempts to select operational connectivity, the terminal implements periodic checking based on stored operational network information. The terminal checks for operational network availability at intervals rather than continuously, reducing service disruption while still achieving network optimization when operational networks are available.

AI summary
Provided is a telecommunication arrangement for switching from a fallback subscription to an operational subscription, the telecommunication arrangement comprising a first agent, PSA, having a list of operational profiles available for the telecommunication arrangement, each operational profile corresponding to a subscription from a MNO, and which of the operational profiles can be used when a telecommunication terminal comprising the telecommunication arrangement enters under the coverage of an operational network, the telecommunication arrangement also comprising a second agent, PSCA, able to configure the fallback subscription in order for the first agent to switch from the fallback subscription to the operational network under which the telecommunication terminal enters under coverage.
