Abstract
A method and system for performing admission control in a packet-based telecommunication network includes a backbone network coupled between at least two access networks. When a first user on a first access network wants to communicate with a second user located on a different access network, a request is made to a quality server whether network resources are available. The quality server separately monitors both access networks and the backbone network and determines whether network resources are available to satisfy the request. In one embodiment, a two-tier approach is used wherein a coordinator module interacts with an admission control subsystem including a plurality of subsystem modules. Each admission control subsystem module is responsible for monitoring a part of the network, such as, one access network or a backbone network. The coordinator module determines which subsystem modules are associated with the user request and interrogates such subsystem modules as to resource availability.

22. A method of performing admission control in a packet-based telecommunication network comprising a backbone network and at least a first and a second access networks connected to the backbone network, each of said backbone and access networks having associated therewith a respective admission control module, comprising the steps of:
-
receiving a request from a first user of the first access network to connect with a second user of the second access network; determining, after the step of receiving, the admission control modules associated with the first and second access networks; and requesting, after the step of determining, the admission control modules associated with the first and second access networks and, if the first and second access networks are separate access networks, the admission control module associated with the backbone network, to check the availability of connection resources for establishing a connection between the first and the second user. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A system for performing admission control in a packet-based telecommunication network comprising a backbone network coupled between at least first and second access networks and a backbone network coupled between the first and second access networks, comprising:
-
an admission control coordinator module configured to receive a request from a first user on the first access network to connect to a second user on the second access network; and at least three admission control subsystem modules coupled to the admission control coordinator module, a first of the admission control subsystem modules configured to monitor the first access network, a second of the admission control subsystem modules configured to monitor the second access network, and a third of the admission control subsystem modules configured to monitor the backbone network. - View Dependent Claims (38, 39, 40, 41, 42)
