<p>A correspondent host (108) that needs to begin a real-time packet-data session with a mobile node (102) sends a mobile IP binding request message (602) to a home agent (106) of the mobile node (102). The correspondent host (108) does not send any further messages until it has received a binding update message (308) in response to the binding request message (602). Upon receipt of the binding update message (308), the correspondent host (108) knows a care-of address of the mobile node (102). A binding to the care-of address is created responsive to receipt of the binding update message (308). An RSVP PATH message (302) is sent by the correspondent host (108) responsive to receipt of the binding update message (308). The RSVP PATH message (302) explicitly binds a data path of a packet flow to the mobile node (102). The correspondent host (108) perceives a RSVP RESV message (310) in response to the RSVP PATH message (302).</p> |
