Communication Device Authorization Notifications for Roaming Data Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In roaming scenarios, there is a need to efficiently manage and update user data processing authorization between different network devices within a Visited Public Land Mobile Network (VPLMN) and a Home Public Land Mobile Network (HPLMN) when user equipment (UE) authorization changes.
Innovation Solution
A method and apparatus that involve sending a notification message from a first network device to a second network device when user data processing authorization changes, allowing the second network device to update user data processing accordingly, and including modules for sending, receiving, and updating user data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user data processing authorization is updated in real-time across network devices, then data processing reliability is improved, but network communication overhead increases
Solution Approach 1:
The system performs preliminary actions by establishing authorization change notification mechanisms in advance. When authorization status changes at the first network device, the system proactively sends notifications to the second network device before the second device attempts data processing, ensuring authorization consistency without continuous polling or real-time synchronization overhead.
2Measurement precision
If authorization changes are promptly notified between network devices, then data processing accuracy is improved, but network signaling overhead increases
Solution Approach 1:
The system extracts and isolates only the essential authorization status information that needs to be communicated between network devices. Instead of transmitting complete data processing contexts or continuous status streams, the invention sends targeted notification messages containing only the critical authorization change indicators, thereby maintaining accuracy while minimizing signaling overhead.
3Adaptability or versatility
If user data processing is updated across roaming networks, then service adaptability is improved, but network device complexity increases
Solution Approach 1:
The system introduces an intermediary notification mechanism between the first network device (home network) and the second network device (visited network). This intermediary authorization notification system simplifies the complexity by providing a standardized interface for authorization status communication, allowing roaming services to adapt to different network configurations without increasing individual device complexity.

AI summary
Information processing methods and apparatuses, a communication device and a storage medium. An information processing method executed by a first network device comprises: when a second network device requests a data processing service of a user equipment (UE) and user data processing authorization of the UE is changed, sending a notification message to the second network device, the notification message being used for notifying the second network device to update user data processing of the UE.
