Determining control of an internet communication between a sender and receiver
First Claim
1. 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.

Abstract
The present invention provides a new communication mechanism between the UE and the GGSN pertaining to Resource Reservation Protocol (RSVP) signaling, and coordinates and assigns responsibility for RSVP messaging. This ensures proper RSVP messaging, prevents unnecessary consumption of radio resources and reduces chances of collisions within the network. Also, the invention prevents the possibility that neither the UE nor GGSN respond appropriately to the RSVP requirements by halting transmission of any RSVP path/refreshment messages to the IP network in order to refresh/maintain the reservation states due to lack of clear assignment of responsibility. This lack of clear understanding between the UE and the GGSN may result in the expiration of the IP network resource reservations made earlier for media streams.
