Abstract: An architecture for resource management of an IP-based cellular radio access network is presented. A measurement-based admission control scheme is used to monitor the load for each path in the network and QoS (quality of service) class and resource decisions are made based upon that information. A bandwidth broker is introduced in the cellular radio access network (RAN). The bandwidth broker processes the on-demand admission requests for IP resources by using the results of load control measurements. Since the requests can be processed very quickly using a simple table look-up, response times are fast, and the architecture is thus suitable for the cellular environment.

Abstract: A method and network subsystem for providing on demand end to end Quality of Service (QoS) in a dynamic manner, use a combination of Resource Reservation Protocol (RSVP), load control protocol (and its successors) and Bandwidth Brokers (BBs) which communicate using a predetermined protocol. The predetermined protocol may be one of Common Open Policy Service Protocol (COPS) and Simple Network Management Protocol (SNMP) for direct communication by the BBs. The network subsystem might also include differentiated services architecture (Diffserv) which might comprise a Diffserv domain including Border Routers (BRs) and Core Routers (CRs). The BBs may obtain resource availability information by communicating only with the BRs to the exclusion of CRs. The BBs may optionally have the capability of using an RSVP aggregation protocol and may have the ability to store and manage RSVP aggregation status.
