UE Warning Message Configuration in Private Mobile Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular systems, particularly in non-public networks like stand-alone non-public networks (SNPNs), lack a standardized mechanism for managing the reception of warning messages, leading to potential misuse or failure in configuring appropriate responses to such messages.
Innovation Solution
Implementing a user equipment (UE) with a warning messages reception configuration that allows accepting or ignoring warning messages based on a configuration provided in the mobile equipment (ME) or universal subscriber identity module (USIM) data, depending on the network access mode, ensuring deterministic operation in both public and non-public networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If warning messages reception is permanently activated in mobile terminal for public networks, then warning messages can be received, but device complexity increases and energy consumption increases
Solution Approach 1:
The patent applies dynamics by making the warning messages reception configuration dynamic rather than permanent. The UE can activate or deactivate reception based on current network context and configuration parameters, allowing the system to adapt between always-on (for reliability) and selective reception (for reduced complexity and energy consumption).
Solution Approach 2:
The patent implements local quality by applying different reception configurations to different network types (public vs. non-public). Instead of a uniform always-activated approach, the system applies specific configuration rules locally to each network context, reducing unnecessary complexity in non-public networks where warning messages may not be needed.
2Reliability
If warning messages reception is permanently activated in mobile terminal, then warning messages can be received, but energy consumption increases
Solution Approach 1:
The patent makes the warning messages reception dynamic by allowing the UE to switch between activated and deactivated states based on configuration parameters and network type. This eliminates the need for permanent activation, reducing energy consumption while maintaining reliability when needed.
Solution Approach 2:
The system implements periodic evaluation of warning messages reception configuration based on network selection and registration events. Instead of continuous permanent activation, the UE periodically assesses whether reception should be active based on current network context, reducing energy consumption while maintaining reliability.
3Device complexity
If UE accepts all warning messages in non-public networks without configuration, then no configuration complexity is needed, but security risk increases due to potential fraudulent alerts
Solution Approach 1:
The patent applies preliminary action by configuring warning messages reception parameters in advance during network selection or registration procedures. The UE obtains and stores configuration parameters from the non-public network before actually receiving warning messages, allowing the system to prepare appropriate security settings and filtering rules beforehand, thus reducing security risks without adding operational complexity.
Solution Approach 2:
The system implements feedback by having the UE receive configuration parameters from the non-public network that indicate whether warning messages should be accepted or ignored. This feedback mechanism allows the network to control security settings dynamically, reducing security risks while keeping device complexity low through automated configuration management.
4Object-affected harmful factors
If UE is configured to ignore warning messages in non-public networks, then security is improved, but reliability of legitimate warning messages decreases
Solution Approach 1:
The patent applies dynamics by making the warning messages reception configuration adaptive rather than static. The UE can switch between accepting and ignoring warning messages based on network-specific configuration parameters received during registration. This allows the system to improve security by ignoring suspicious messages while maintaining reliability for legitimate warnings when the configuration indicates acceptance.
Solution Approach 2:
The patent implements local quality by applying different reception policies to different non-public networks based on their specific configuration parameters. Instead of a blanket ignore-or-accept rule, the system locally adapts the reception behavior to each network's security requirements and legitimacy indicators, thus improving security without sacrificing reliability for legitimate messages.
5Adaptability or versatility
If UE processes warning messages configuration during network selection procedure, then configuration is optimized, but processing time increases
Solution Approach 1:
The patent applies preliminary action by processing warning messages configuration during the network selection and registration procedures, which occur before normal operation. This allows the system to optimize configuration settings in advance without adding processing time to critical operations, as the configuration is prepared beforehand when the UE is already establishing network connectivity.
