Abstract
A heterogeneous wireless communication network includes a home access network with a home network characteristic and a home network policy, and a visiting access network with a visiting network characteristic and a visiting network policy. A packet data node gateway is adapted to communicate with the home access network and the visiting access network over a first communication path. An out-of-band communication path substantially separate from the first communication path is adapted to carry the visiting network policy from the visiting access network to the packet data node gateway. When the terminal is handed off from the home network to the visiting network, the packet data node gateway retrieves the visiting network policy, and the terminal accesses the visiting network over the first communication path using the visiting network policy.
