Examples of Use Cases

SS7 Integration for Billing Systems

The IN Gateway enables real-time control of calls, SMS and data based on the CAMEL ( in UMTS networks) or WIN (in CDMA networks) protocols, which is essential for integration of 3rd party billing services to SS7 networks.

Value-Added Services Integration

A unique RESTful HTTP API enables service providers to develop and integrate vendor-independent Value-Added Services (VAS) without the need to have a deep understanding of the SS7 protocol stack.


Many networks around the world with 4G LTE deployed still rely on their 3G infrastructure for voice and SMS services. In order to integrate billing between the 3G and 4G networks, an interworking function is needed.

Cross-technology Interworking Function

Modulo’s Intelligent Network Gateway performs various non-standard conversions between GSM, CDMA and LTE network elements. Such conversions are usually utilized in prepaid billing and real-time charging scenarios which require bridging between 2G/3G and 4G networks. The IN-GW performs the following conversions:

  • CAMEL (CAP) to Diameter (Ro interface)
  • Diameter (Ro interface) to CAMEL (CAP)
  • WIN (CDMA) to Diameter
  • Diameter to WIN (CDMA)

Conversions between CAMEL (UMTS) and WIN (CDMA) (and vice-versa) are essential for Inter-standard roaming. Some mobile operators around the world utilize both UMTS and CDMA infrastructures in the same network, and require a solution such as our Intelligent CAMEL gateway in case the operators want to use a single network-wide billing server.
