ABSTRACT:
In the UMTS, resource reservation is provided by using unidirectional RSVP messages to set up a bi-directional PDP context. The MT30and a support node24can be arranged to compare incoming RSVP messages with any existing secondary PDP context, and if a match is found, no action is taken on the incoming message. The match is made by determining whether a flag is set. This eliminates “racing” when each end of an RSVP session sends an RSVP message.
