–continuation of communication after interruption of link possible
–point of connection to the fixed network can be changed
nCompatibility
–support of the same layer 2 protocols as IP
–no changes to current end-systems and routers required
–mobile end-systems can communicate with fixed systems
nSecurity
–authentication of all registration messages
nEfficiency and scalability
–only little additional messages to the mobile system required (connection typically via a low bandwidth radio link)
–world-wide support of a large number of mobile systems in the whole Internet
