Connection Admission Control in the UTRAN Transport Network
In this paper we propose a Connection Admission Control (CAC) algorithm to provide Quality of Service (QoS) in UMTS Terrestrial Radio Access Networks (UTRAN). In UTRAN, the main QoS requirement is to ensure low packet delays. The CAC algorithm works with priority scheduling, which is used for QoS differentiation. We give a detailed investigation on the performance implications of applying prior...
متن کاملImpacts of Air Interface Call Admission Control on UTRAN Transport Simulations
This paper investigates the potential impacts caused by Call Admission Control (CAC) mechanism of the air interface on simulations carried out for the transport network domain of UMTS Radio Access Network. Independent from the TNL CAC mechanism of the transport network which is in charge of Iub link bandwidth, the Radio CAC function deals with the highly non-linear resources needed for an attem...
متن کاملPerspective on Connection Admission Control
| We propose a minimum cost method for trafc shaping in the context of QoS-based networks. Given the user's desired QoS and the network's resource availability, our procedure determines the least-cost parameters for a tra c shaper which still guarantees access to the network whilst satisfying the QoS constraints. We illustrate our scheme using on-o sources and formulate the QoS constraints by e...
متن کاملConnection admission control - closing the loop
Absfroct-To date, many Connection Admhsion Contml (CA0 Schemes have been pmpnsed. These scheme can he generally classified into two categories: measurement-based CAC and traffic descriptor-based CAC. Both categories adopt an open-Imp arehitecture where traffic parameten am ohtained fmm either on-lhe measurements or user-speci6cations and then input into a chosen traffic and network model to mak...
متن کاملCapacity Analysis for Connection Admission Control in
In this paper, the capacity analysis for connection admission control is presented for the reverse-link transmission of a packetized indoor multimedia wireless communication system using direct sequence code division multiple access (DS/CDMA). Since CDMA is interference limited, the signal-to-interference-plus-noise ratio criterion is used to check if there is enough system resources (i.e., the...
