Network Access Failure Cause Value Transmission for M2M Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile networks do not record or notify failure causes for user equipment attachment or access failures in M2M communication services, preventing applications from diagnosing terminal network access failures and performing appropriate processing.
Innovation Solution
The proposed solution involves sending a message to user equipment to request data, receiving a message with a network access failure indication, and sending the failure cause value to a home subscriber server or failure cause processing entity when a network access failure is determined, allowing for failure diagnosis and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the mobile network does not record failure cause values, then the network operation is simple, but applications cannot diagnose terminal network access failures
Solution Approach 1:
The network side proactively sends a notification message to the application server before the application needs to diagnose failures, containing the failure cause value. This preliminary action ensures that failure information is already available when needed, eliminating the need for complex on-demand querying mechanisms.
Solution Approach 2:
The patent introduces an intermediary notification mechanism where the network side (MME/SGSN) acts as a mediator between the access failure event and the application server. This intermediary automatically transmits failure cause information without requiring direct complex interactions between all network elements and applications.
2Reliability
If the network records and notifies failure causes, then applications can perform failure diagnosis, but the network complexity increases
Solution Approach 1:
The network pre-configures and sends notification indicators to application servers, enabling them to receive failure cause information proactively. This preliminary setup allows reliable failure diagnosis without requiring complex real-time processing mechanisms during actual failure events.
Solution Approach 2:
The patent establishes a feedback loop where the network side monitors access failures and automatically notifies application servers with cause values. This feedback mechanism ensures reliable failure diagnosis while maintaining manageable network complexity through automated, rule-based notification processes.
3Adaptability or versatility
If the application server can acquire failure cause values, then appropriate processing can be performed, but additional network elements and protocols are required
Solution Approach 1:
The notification message structure is designed to be universal, carrying failure cause values that can be used by various application servers for different processing needs. This multi-functional approach allows diverse applications to benefit from the same notification mechanism without requiring application-specific network elements.
Solution Approach 2:
The patent uses a standardized intermediary notification mechanism that bridges the network and diverse applications. This universal intermediary translates various failure types into a common notification format, enabling versatile application processing without requiring complex application-specific protocols for each failure type.
