Insert in Section 5.5 following the last paragraph

The messaging exchanges between peer MIH Function instances, in particular the type of transport that they use, are sensitive to several factors, such as the nature of the network nodes that contain the peer MIH Function instances (whether or not one of the two is a Mobile Node or a PoA), the nature of the access network (whether IEEE 802 or 3G cellular), and the availability of MIH capabilities at the PoA.

Figure 5 presents a summary of the types of relationship that may exist between the MIH Function and other functional components in the same network node, and between the MIH Function and a peer MIH Function instance residing in a different network node.

Figure 5 Types of MIH Function relationship (option 1)

The General MIH Reference Model in Figure 4 enables a simple representation of the broad variety of MIH Function relationships shown in Figure 5. In the Model, a mobility-management protocol stack is logically identified within each network node that includes an MIH Function instance. The abstraction provided makes it easy to isolate and represent the MIH relationships with all pre-existing functional entities within the same network node. Such relationships are both internal (with functional entities that share with the MIH function the logical inclusion in the mobility-management protocol) and external (with functional entities that belong to other planes).
