Intermediary Gateway Error Reporting for SEPP Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks face challenges in detecting and reporting error conditions in traffic handling by intermediary gateways, such as connectivity issues, authorization problems, and interface-specific issues, which can lead to communication disruptions and unauthorized data exchange.
Innovation Solution
Implementing intermediary gateways with error detection and reporting capabilities, which analyze traffic against predefined parameters and policies, identify error conditions, and communicate these issues to Security Edge Protection Proxies (SEPPs) or other network functions, enabling remedial actions and improved network reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If intermediary gateways are deployed to manage traffic routing and forwarding between SEPPs, then network traffic management and policy enforcement are improved, but undetected error conditions can lead to communication disruptions and security vulnerabilities
Solution Approach 1:
The intermediary gateway implements error detection and reporting functionality that continuously monitors traffic handling operations and provides feedback about error conditions to the SEPPs. This feedback mechanism enables the network to detect and respond to errors in real-time, resolving the contradiction by maintaining both ease of operation and communication reliability.
Solution Approach 2:
The intermediary gateway acts as a mediator between SEPPs, not only for traffic routing but also for error detection and reporting. This intermediary role allows the gateway to monitor traffic handling operations and communicate error conditions to the appropriate SEPPs, thereby improving reliability while maintaining operational simplicity.
2Reliability
If error detection and reporting functionality is implemented in intermediary gateways, then network reliability and security are improved, but device complexity increases
Solution Approach 1:
The intermediary gateway leverages its existing mediating role in traffic routing to also perform error detection and reporting functions. By utilizing its position as an intermediary between SEPPs, the gateway can monitor traffic handling operations and report errors without requiring substantial additional complexity, thus improving reliability while minimizing the increase in device complexity.
3Difficulty of detecting and measuring
If traffic is monitored and analyzed against predefined parameters and policies, then error detection capability is improved, but processing time and computational resources increase
Solution Approach 1:
The intermediary gateway uses predefined parameters and policies for error detection, which are established in advance. This preliminary configuration allows the gateway to quickly compare traffic handling operations against known error conditions without requiring complex real-time analysis, thereby improving error detection capability while minimizing processing time and computational resource requirements.
Data Source
AI summary
A device described herein may establish a communication session with a first Security Edge Protection Proxy (“SEPP”) of a first network, and further with a second SEPP of a second network. The device may be or may implement an intermediary gateway between the SEPPs. The communication session may be associated with an N32-F interface that includes the SEPPs, the intermediary gateway, and one or more other intermediary gateways. The device may receive traffic from the first SEPP, and may determine that the traffic satisfies one or more error conditions. The device may identify an error reporting policy associated with the identified error condition, and may output, to the first SEPP and/or to the second SEPP (e.g., in accordance with the error reporting policy), an indication that the traffic satisfies the one or more error conditions.
