Abstract
Two-way resource reservation techniques for use in UMTS and other telecommunication systems. A determination is made as to whether a user requires resource reservations in both an uplink direction and a downlink direction within the system, and if the user requires such two-way resource reservations, a two-way protocol is implemented to establish the required resource reservations. The two-way protocol integrates resource negotiation procedures for both the uplink direction and the downlink direction so as to ensure that the required resource reservations are provided for both directions. The two-way protocol may be a Packet Data Protocol (PDP) based on a Resource Reservation Protocol (RSVP) resource negotiation procedure. The determination may be based on one or more flag bits which identify whether the user requires resource reservations for both the uplink and downlink directions. The flag bits may be associated with a Quality of Service (QoS) Information Element (IE) of the system, and may be used to permit the user to select between application of the two-way protocol and application of a one-way protocol.
