On optimal call admission control in cellular networks
Proceedings of IEEE INFOCOM '96. Conference on Computer Communications, 1997Two important Quality-of-Service (QoS) measures for current cellular networks are the fractions of new and handoff “calls” that are blocked due to unavailability of “channels” (radio and/or computing resources). Based on these QoS measures, we derive optimal admission control policies for three problems: minimizing a linear objective function of the ...

Call admission control in wireless multimedia networks
The 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2003This paper addresses the call admission control problem for the multimedia services that characterize the third generation of wireless networks. In the proposed model each cell has to serve a variety of classes of requests that differ in their traffic parameters, bandwidth requirements and in the priorities while ensuring proper quality of service ...

On optimal call admission control
Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 2002In this paper call admission control of multiple classes to a group of servers without waiting room is considered. For the original model several structural results are derived. Its fluid model is then formulated, and the optimal control is studied.

Impact of Mobility on CDMA Call Admission Control
IEEE Transactions on Vehicular Technology, 2006Interference is the key parameter in a code-division multiple access (CDMA) network. As users move around, the interference will flow with the movement. The objective of this paper is to study the impact of the moving interference (mobility) on systems' performance and design parameters. In this paper, we develop a detailed CDMA interference model with

Unified call admission control in corporate domains
Computer Communications, 2020Abstract Call Admission Control is a central mechanism for assurance of quality of service in telephony. While CAC is integrated into Public Switched Telephony Network (PSTN), its application to voice over IP in a corporate environment is challenging not only due to the heterogeneity of technologies, but also because of the difficulty of ...

CAC-RD: an UMTS call admission control
Telecommunication Systems, 2010The third wireless network generation (3G) aims to provide fast Internet access with quality of service (QoS) guarantees, especially to multimedia applications. UMTS (Universal Mobile Telecommunication System) is a kind of 3G networks. To provide QoS, the network must use an efficient admission control mechanism.

Call Admission Control in Hierarchical Mobile Networks
10th IEEE Symposium on Computers and Communications (ISCC'05), 2005Mobile networks are requested to provide several added value services with different QoS levels. An efficient call admission control (CAC) is one of the strategic components that a network management policy requires, which defines how to allocate network resources to roaming and new users.

Call Admission Control Optimization in WiMAX Networks
IEEE Transactions on Vehicular Technology, 2008Worldwide interoperability for microwave access (WiMAX) is a promising technology for last-mile Internet access, particularly in the areas where wired infrastructures are not available. In a WiMAX network, call admission control (CAC) is deployed to effectively control different traffic loads and prevent the network from being overloaded. In this paper,

Call admission control in DCA wireless network
Ninth IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (Cat. No.98TH8361), 2002A novel call admission control (CAC) scheme based on dynamic channel allocation (DCA) is proposed for cellular networks. The scheme combines the advantage of high channel availability of DCA with quality of service guarantees of CAC. Our scheme uses statistical bandwidth reservation for handoff events.
