Aggregated signaling methods and apparatus which can be used to support the aggregation of Mobile IP binding registration information corresponding to multiple forwarding tunnels are described. Aggregated binding update message are used to enable multiple home addresses from one or more home agents
Aggregated signaling methods and apparatus which can be used to support the aggregation of Mobile IP binding registration information corresponding to multiple forwarding tunnels are described. Aggregated binding update message are used to enable multiple home addresses from one or more home agents to be installed, refreshed and deleted using a single MIP signaling phase. The single MIP signaling phase may correspond to a single MIP binding update message. Aggregated message techniques can also be used to retrieve multiple home address specific policy profiles via AAA signaling thereby reducing the number of AAA messages required to retrieve AAA information, e.g., profiles, corresponding to multiple home addresses.
