  11. 5. summary Summary 5. 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 services can be offered to the mobile subscribers roaming in HPLMN or VPLMN
