Roaming Error Message Encryption via Entity-Specific Keys
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for error message generation and processing in network deployments enabling roaming between connected networks are not well specified, leading to inefficiencies and security concerns in error handling.
Innovation Solution
The proposed solution involves methods and apparatuses for generating and processing error messages in network entities associated with roaming services. These include receiving and deciding on the handling of error messages based on error cause information, as well as encrypting and transmitting error messages to ensure secure and efficient error notification handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If error messages are transmitted in plaintext for easy processing, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent introduces an intermediary encryption mechanism where error cause information is encrypted using receiving entity identifiers as keys before transmission. The receiving entity then decrypts and processes the information. This mediator (encryption/decryption process) enables secure transmission while maintaining ease of processing, as the receiving entity can still efficiently access and handle the error information through automated decryption based on its identifier.
2Measurement precision
If detailed error cause information is included in error messages, then measurement precision is improved, but loss of information is worsened due to security constraints
Solution Approach 1:
The patent applies local quality by encrypting error cause information specifically for each receiving entity using that entity's identifier as the encryption key. This allows different levels of information accessibility - each entity receives encrypted information tailored to its security context, enabling detailed error diagnosis for authorized entities while maintaining security constraints. The encryption is localized to each receiving entity rather than applying a uniform security measure to all error messages.

AI summary
There are provided measures for error message generation and processing. Such measures exemplarily comprise, at a first network entity associated with a first network roaming interconnected with a second network, receiving a message indicative of a roaming service related error, wherein said message includes first error cause information related to said roaming service related error and addressed to said first network entity, and deciding on further handling of said message based on said first error cause information.
