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
