Summary

IN-concept has existed for some twenty years

IN have now a very powerful set of tools for the provision of new,

advanced and highly customizable services in a modern

telecommunications network

CAMEL is standardized by ETSI/3GPP in four phases; the main CAMEL

standards are 22.078, 23.078 and 29.078

CAMEL is based on a modification of IN INAP protocol, called CAP

(CAMEL Application Part) and Mobile Application Part (MAP) protocol

CAMEL integrates stepwise IN techniques from fixed to mobile network

CAMEL is an IN technology by the help of which value-added servicescan be offered to the mobile subscribers roaming in HPLMN or VPLMN
