Introduction The MIH L3 transport problem can be divided in two parts Discovery Process required for the MIHF at the Mobile Node (MN) to discover the peer MIHF (e.g. IP address) of the Mobility Services (MoS) in the network, e.g. PoS (Point of Service), either during initial attachment or during handover Transport This is the service provided to allow the communication between two MIHFs via MIH protocol once they discover each other Security aspects are considered together with the Transport service Candidate solutions for both aspects have been evaluated Existing standard track IETF-based solutions have been given preference |
