Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Diameter protocol is dynamically customized and adjusted by using Vendor Specific Attribute Value Pairs (AVP's), then flexibility is improved, but interoperability and security issues worsen
Solution Approach 1:
The patent introduces a gateway server as an intermediary component between Diameter signaling peers from different service providers. This gateway implements protocol mediation functionality that normalizes Vendor Specific AVP's into standardized formats, enabling flexible customization at each provider's end while ensuring interoperability and security through centralized mediation and validation of signaling messages.
2Adaptability or versatility
If home network receives Diameter commands from other networks with varying messages structure, content types and content values, then roaming capability is improved, but security and interoperability problems worsen
Solution Approach 1:
The gateway server acts as a mediator that receives Diameter commands from external networks with varying message structures and content types. It implements normalization functions that convert these diverse formats into standardized internal representations, applies security validation rules, and ensures interoperability before forwarding messages to the home network, thereby enabling roaming while maintaining security and reliability.
Solution Approach 2:
The patent applies parameter changes by transforming varying message structures, content types, and content values into standardized formats. The gateway server dynamically adjusts message parameters including AVP encoding, data types, and structural organization according to predefined normalization rules specific to each equipment type and vendor, enabling seamless roaming while maintaining consistent security and interoperability standards.
3Adaptability or versatility
If gateway servers require customization for configuring the gateway for adapting between different protocols, then protocol adaptability is improved, but device complexity worsens
Solution Approach 1:
The patent reduces gateway configuration complexity by implementing automated parameter change mechanisms. The system maintains equipment type-specific profiles containing predefined normalization rules for message structures, AVP formats, and protocol adaptations. When a new equipment type or vendor is detected, the gateway automatically retrieves and applies the corresponding profile, eliminating manual customization while maintaining comprehensive protocol adaptability across different service providers.

AI summary
The present invention disclose a system and method for mediating between signaling network peers of diameter type, where each peer is associated with different telecommunication service providers network or different application vendors. The method comprise the steps of: identifying equipment application type and release version of each provider based on pre-defined automatic identification classification rules and profile, classifying the vendor of the implemented diameter application in each signaling peer, retrieving a first set of rules adapted for the identified source equipment type, intercepting messages of communication session between signaling peers of different providers, applying steering rules on outgoing requests for selecting the destination route of target peers, retrieving a second set of conversion rules adapted for the identified destination equipment type vendor application relating to messages structure, content types and content values and applying all conversion rules on intercepted messages for translating between messages formats of the different signaling peers.
