UE Warning Message Configuration in Non-Public Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user equipment (UE) devices are not adequately configured to handle warning messages in non-public networks, such as stand-alone non-public networks (SNPNs), leading to potential misuse or failure in receiving and processing public warning messages.
Innovation Solution
A configuration mechanism is provided within the UE to manage warning message reception, allowing the UE to accept or ignore messages based on specific settings for non-public networks, even when the Universal Subscriber Identity Module (USIM) data is absent or empty, ensuring proper handling of warning messages in both public and non-public networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE accepts all warning messages in non-public networks by default, then warning message reception coverage is improved, but susceptibility to fraudulent alerts increases
Solution Approach 1:
The patent applies local quality by differentiating warning message reception behavior between public and non-public networks. The UE is configured to accept warning messages in public networks by default, while requiring explicit configuration for non-public networks. This localized differentiation allows the system to maintain high reception coverage in trusted public networks while applying stricter controls in non-public networks to prevent fraudulent alerts.
Solution Approach 2:
The patent implements preliminary action by configuring warning message reception parameters before the UE actually receives warning messages in non-public networks. The network provides configuration information (such as PLMN IDs or network identifiers) in advance, allowing the UE to pre-establish acceptance criteria. This ensures that when warning messages arrive, the UE can quickly determine whether to accept them based on pre-configured trust relationships, rather than making decisions in real-time.
2Object-affected harmful factors
If UE requires configuration for warning message reception in non-public networks, then security against fraudulent alerts is improved, but device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the network to automatically provide configuration information to the UE for warning message reception in non-public networks. Instead of requiring manual user configuration or complex device-side security policies, the network autonomously delivers relevant configuration parameters (such as acceptable PLMN IDs or network identifiers). This reduces device complexity while maintaining security, as the configuration management burden is shifted to the network side which can centrally control security parameters.
3Object-affected harmful factors
If UE ignores warning messages in non-public networks, then protection from fraudulent alerts is improved, but ability to receive legitimate warnings deteriorates
Solution Approach 1:
The patent implements dynamics by making warning message acceptance in non-public networks configurable rather than static. The UE can dynamically switch between ignoring and accepting warning messages based on network-provided configuration information. This allows the system to adapt to different non-public network contexts - ignoring messages from untrusted networks while accepting messages from trusted networks that have been properly configured. The dynamic configuration approach resolves the contradiction by allowing both protection from fraudulent alerts and reception of legitimate warnings under different conditions.

AI summary
User equipment and method for receiving warning messages in a non-public mobile communications network. The user equipment accepts or ignores warning messages received in the non-public mobile communications network based on a warning messages reception configuration stored in a memory of the user equipment such as a memory of the mobile equipment part of the user equipment.
