Wireless DNN Corruption Detection and Session Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corrupted Data Network Names (DNNs) in wireless communication networks lead to issues with wireless user devices' ability to properly use communication services, causing resource wastage and inefficiencies due to incorrect associations with network slices and user policies.
Innovation Solution
A wireless communication network system that detects and corrects corrupt DNNs by transferring reattach messages and establishing new data sessions, allowing user devices to maintain communication services without disrupting other data sessions, using Access and Mobility Management Function (AMF), Session Management Function (SMF), and Unified Data Management (UDM) to manage DNNs effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wireless network core uses DNNs to select network functions and manage data sessions, then service delivery and resource management are improved, but corrupt DNNs cause service failures and resource wastage
Solution Approach 1:
The system implements a feedback mechanism where the wireless network core monitors DNN usage and detects corruption. When corrupt DNNs are identified, the system triggers corrective actions including notifying the wireless access node to terminate affected data sessions and preventing further usage of corrupt DNNs. This closed-loop feedback ensures service reliability while maintaining efficient resource management.
Solution Approach 2:
The patent introduces an intermediary detection and management mechanism between the wireless access node and the wireless network core. This intermediary layer monitors DNN associations, detects corruption, and coordinates corrective actions across multiple network functions (AMF, SMF, UPF) to resolve service failures caused by corrupt DNNs without disrupting overall network operations.
2Reliability
If the system terminates data sessions to correct corrupt DNNs, then service reliability is improved, but other data sessions may be disrupted
Solution Approach 1:
The system segments the correction process to affect only specific corrupted data sessions rather than all sessions. When corrupt DNNs are detected, the wireless access node selectively terminates only the data sessions associated with those specific corrupt DNNs, while leaving other healthy data sessions uninterrupted. This segmented approach maintains service reliability for affected sessions while preserving productivity for unaffected sessions.
3Loss of energy
If the wireless access node monitors and corrects corrupt DNNs, then resource wastage is reduced, but device complexity increases
Solution Approach 1:
The wireless access node performs self-service monitoring of DNN associations and automatically detects corruption without requiring external intervention. When corrupt DNNs are identified, the system autonomously triggers correction procedures including terminating affected data sessions and updating local DNN configurations. This self-service capability reduces resource wastage from corrupt DNN usage while avoiding the need for additional external monitoring infrastructure.
Data Source
AI summary
A wireless communication network serves a wireless User Equipment (UE). The wireless UE exchanges user data over a data session of a Dynamic Network Name (DNN) while exchanging other user data over other data sessions of other DNNs. An Access and Mobility Management Function (AMF) receives a DNN message for the wireless UE and the DNN and responsively transfers a reattach message for the data session of the DNN to the wireless UE. The wireless UE receives the reattach message and responsively terminates the data session of the DNN and transfers a session message for the DNN to the AMF. The AMF receives the session message for the DNN and the wireless UE and responsively establishes a new data session for the DNN. The wireless UE exchanges new user data over the new data session of the DNN while exchanging additional user data over the other data sessions of the other DNNs.
