Patent ID: 7287070

Claim:
A method for a general packet radio service gateway (GGSN) to dynamically assign responsibility for controlling resource reservation protocol (RSVP) in order to support multimedia communications between a user equipment (UE) in a wireless communication network and a user of an external network, the method comprising: determining whether the GGSN or the UE will perform the RSVP signaling; if the GGSN determines the UE will perform the RSVP signaling; the GGSN, sends the UE a message indicating that the UE will control the RSVP function; and the UE signals the external network in order to reserve a path through the external network; if the GGSN determines the GGSN will perform the RSVP signaling; the GGSN sends the UE a message indicating that the GGSN will control the RSVP function; and the GGSN signals the external network in order to reserve a path through the external network; and dynamically reallocating control of the RSVP function to either the GGSN or the UE.
