CAMEL Adaptation System for Roaming Test Complexity

The patent introduces a CAMEL Adaptation System (CAS) as an intermediary component that sits between the home network and visited network elements. The CAS performs message adaptation, phase conversion, and protocol translation, thereby enabling roaming services without requiring complex bilateral testing between every operator pair. The CAS mediates the interaction between different CAMEL implementations, reducing testing complexity while maintaining reliability.

The patent creates virtual copies of CAMEL subscription information and service profiles that can be replicated and distributed to multiple visited networks. Instead of conducting extensive testing with each individual network, the adapted CAMEL profiles are copied and deployed across the CAS infrastructure, allowing consistent roaming service verification without repeated complex testing scenarios.

The patent segments the CAMEL adaptation functionality into distinct modules within the CAS, each handling specific CAMEL phases (Phase 1, Phase 2, Phase 3, Phase 4). Each module processes messages according to its specific phase requirements, allowing the system to support multiple CAMEL phases without creating a monolithic complex system. The segmentation enables independent configuration and maintenance of each phase adapter.

The patent implements dynamic CAMEL phase adaptation where the CAS can automatically detect the CAMEL phase being used by a visited network and dynamically switch between different adaptation modes. The system dynamically configures message routing, adaptation rules, and protocol handlers based on the detected CAMEL phase, providing versatility without requiring manual reconfiguration or static complex architecture.
