In the migration to all-IP LTE Networks, the expectation is that Diameter will replace CAMEL/WIN. Without support for the CAMEL/WIN signaling Protocol in LTE, and lack of capabilities to link the two technologies, Operators end up having to support multiple, silo-based charging environments.
Introduction of a Protocol Interworking Gateway between the new Diameter based billing domain and existing legacy CAMEL billing. This Gateway will act as a Diameter host to the new Diameter based billing domain and will convert all CAMEL/WIN related billing messaging to Diameter. The Interworking Function will be capable of converting all proprietary CAMEL information to correct Diameter AVP's.
Lifetime extension of the existing CAP based assets and services
Because we will convert CAMEL messaging from legacy services (as Voice and SMS) into Diameter we will extend the lifetime of those CAP based assets.
Immediate availability of a complete CAMEL/WIN Interworking solution
A tested and accepted solution is available that enables CAMEL/WIN Interworking for the integration of legacy pre-paid systems for Voice, SMS and Data with Diameter based systems.
Providing the required business logic and stateful processing that applies to the IN-services involved
Flexibility to convert messages into customer specific format
On-the-fly adaptations to any (proprietary) Diameter or SS7 variant are possible through built-in flexibility to quickly adjust and customize interfaces to specific customer environments, new use cases and future system updates. There is no more dependency on the R&D availability of vendors.
Single-Diameter based billing system for both 4G/LTE and legacy domains
Lifetime extension of CAP based assets and services
