A method and system of transferring data rate and state information of
mobile nodes between access and home networks is provided. A mobile node
may register with a foreign agent on a foreign network, by sending mobile
node information, such as a data rate at which the mobile node operates
and a dormancy status of the mobile node, to a radio access network,
which forwards the information to the foreign agent. The foreign agent
may then contact a home agent on the mobile node's home network to setup
a call. The foreign agent may send the mobile node information, such as
the data rate or the dormancy state, to the home agent during call-setup
or during the call as well.
