Robust Compatibility Mode for Legacy UE Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compatibility issues between user equipment (UE) and networks can hinder new feature rollouts and user experience, particularly due to legacy UE incompatibilities, inconsistent implementations, and outdated software versions, which existing solutions like over-the-air upgrades may not fully address, especially in scenarios where UE vendors no longer support software updates or when issues are specific to local operators.
Innovation Solution
The implementation of a robust compatibility mode (RCM) using robust communication resources (RCR) allows UE and networks to resolve compatibility issues through software upgrades or other mechanisms, ensuring feature set compatibility across varying market requirements without impacting key performance indicators (KPIs) by establishing a safe communication mechanism for problematic UEs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If over-the-air software upgrades are used to address compatibility issues, then UE compatibility can be improved, but device complexity and user control are reduced
Solution Approach 1:
The system dynamically switches between normal operation mode and robust compatibility mode based on detected compatibility issues. The RCM configuration can be activated or deactivated depending on the situation, allowing the system to adapt its behavior without permanent structural changes or complex update mechanisms.
Solution Approach 2:
The invention changes operational parameters by introducing a specific RCM configuration that modifies how the UE communicates with the network. This configuration includes specific message structures and protocols that enable compatibility without requiring software updates, thus maintaining device simplicity.
2Reliability
If robust compatibility mode is implemented to resolve compatibility issues, then UE network access reliability is improved, but communication protocol complexity increases
Solution Approach 1:
The invention extracts and isolates the compatibility handling into a separate, dedicated mode (RCM) that is only activated when needed. This separates the complex compatibility resolution logic from the normal communication protocol, keeping the standard protocol simple while providing a specialized solution for compatibility issues.
Solution Approach 2:
The RCM configuration acts as an intermediary layer between the UE and the network when compatibility issues arise. It provides a standardized mediation mechanism that simplifies the interaction by establishing predetermined message structures and procedures, reducing the need for complex ad-hoc solutions.
3Adaptability or versatility
If RCM configuration is provided through system information blocks, then compatibility issue resolution is enabled, but network signaling overhead increases
Solution Approach 1:
The RCM configuration is integrated into existing system information blocks that serve multiple purposes in network communication. By utilizing already-established signaling structures for broadcast information, the invention avoids creating separate dedicated signaling channels, thus minimizing additional overhead while providing universal compatibility support.

AI summary
The present disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for robust compatibility mode communication. A user equipment may determine whether a robust compatibility mode (RCM) is supported between the UE and the base station. The UE also may establish a RCM connection with the base station when the RCM is supported between the UE and the base station. The UE also may receive, from the base station, through the RCM connection, a configuration associated with the RCM. The UE also may update a behavior of the UE for a current situation of the UE based on the configuration. The UE also may transmit, to the base station, a request to access a wireless network with the updated behavior of the UE.
