At present time it is broadly recognized the existence of three generations of mobile telephone systems. In this work it is analysed the evolution of the three generations systems in terms of the services provided in each generation, focusing in the entity known as CAMEL (Customized Applications for Mobile Networks Enhanced Logics), which is an important platform influencing the evolution of 2G and 3G and beyond mobile telephony systems. This work starts with a general overview of mobile telephone systems, their architectures and services platforms, going further into the evolution of CAMEL that occurs together with the evolution of third generation system UMTS (Universal Mobile Telecommunications System) and would play an important role when the “all-IP” network and multimedia applications become part of everyday use by million of subscribers part of the mass market. CAMEL evolution is important as it is the evolution of 3G into 4G networks such as Ambient Networks, where CAMEL will be a fundamental element in order to make it easy the creation, control, and establishment of advanced and personalized services to subscribers, wherever they would be, and whenever they require the services, with full mobility and service portability, independently of the radio-access technology, the networks and the operators.
