TONEX’s CAMEL Training, Customized Applications for Mobile Enhanced Logic Training Course
CAMEL training (Customized Applications for Mobile Network enhanced Logic) provides a comprehensive, up-to-date, and easy to understand treatment of business, technical and operational aspects of CAMEL (Customized Applications for Mobile Enhanced Logic) applied to 3GPP networks.

CAMEL is a network feature and not a supplementary service and a value added tool for the mobile operators to provide the subscribers with the operator specific services even when roaming in the another network.

CAMEL is evolved with several phases to provide mobile operators with CAMEL functionality applied to different features.  The CAMEL application protocol (CAP) was built on the top of Intelligent Networks (IN) and ETSI’s INAP.

TONEX CAMEL training is a is a technical course covering IN and CAMEL key concepts, architecture, phases, features, service logic design, Operations & Parameters, signaling procedures,  call flows, and future trends for CAMEL evolving of SIP and Diameter protocols as alternative solutions based on PCRF and On line and Offline Charging System (OCS/OFCS).
