In such a globalised world where distances are becoming shorter and shorter while industry and economy broaden and widen, mobility represents definitely a hot topic for network operators. Moreover, network architectures are evolving continuously under the precepts stated by ITU-T Next Generation Networks. However, there are some former widely deployed and accepted network architectures which will have to coexist with the latter. This paper aims to analyse inter-domain handovers involving current (3GPP technologies) and future (pure all-IP technologies) communication platforms based on use-cases, paying special attention to the main challenges that have to be faced in each situation. It aims to figure out how inter-domain handovers could be managed, analysing for this purpose different scenarios involving current and future network architectures.
