The main requirement for a mobile IP is that the mobile IP has to be compatible with all lower layer used for standard, non mobile, IP. Mobile IP should remain invisible to higher layers and applications. The end systems enhanced by the implementation of mobile IP must be able to communicate with the fixed systems since in current situation fixed systems are in huge amount and working in all over the world. The effects of mobility include higher delay and low bandwidth so there is also a requirement for bandwidth aware applications. The mobility could cause huge routing advertisements that could possibly flood the whole network so special care regarding efficiency is required.
FCC.gov has a guide over what this it and how it works. Also they got information about what you will need for it and much more that you might need to know about Voice Over IP.
