Evaluation of call blocking probabilities in LEO satellite networks
International Journal of Satellite Communications and Networking, 2009 AbstractIn this paper, we present a new method for calculating call blocking probabilities (CBPs) in a low Earth orbit satellite network that carries voice calls. The calculation of the CBPs uses the Erlang‐B formula, but the traffic intensity has been modified to take into the time and location in which the calls are made. Copyright © 2009 John Wiley &

Computing call-blocking probabilities in leo satellite constellations
IEEE Transactions on Vehicular Technology, 2003 We present an analytical model for computing call-blocking probabilities in a low Earth orbit (LEO) satellite network that carries voice calls. Both satellite-fixed and Earth-fixed constellations with interorbit links and handoffs are considered. We assume a single beam per satellite.

Analysis of call blocking probability in TDM/WDM networks with transparency constraint
IEEE Communications Letters, 2000 In this letter we devise and validate by simulation an analytical model to study the performance of TDM/WDM networks using a three-stage switching architecture as an abstract model. We consider the transparency property as a constraint: a new incoming call can be accepted only without modifying the routing of previously accepted calls.

Call–burst blocking and call admission control in a broadband network with bursty sources
Performance Evaluation, 1999Summary: In this paper we consider call-burst blocking and call admission control in a broadband network with bursty sources. We assume a multiple-link network with several classes of calls, each class following a fixed path in the network and requiring a fixed number of channels from the links on its path.

Proportional fairness of call blocking probability
Proceedings of the 2nd International Conference on Interaction Sciences: Information Technology, Culture and Human, 2009To guarantee proportional fairness (PF) is an important way to realize predictable and controllable service differentiation. In this paper, a proportional differentiation call admission control (CAC) algorithm, named PBS-PF, is proposed to guarantee the network services' PF in terms of call blocking probability (CBP).

New call blocking versus handoff blocking in cellular networks
Wireless Networks, 1997In cellular networks, blocking occurs when a base station has no free channel to allocate to a mobile user. One distinguishes between two kinds of blocking, the first is called new call blocking and refers to blocking of new calls, the second is called handoff blocking and refers to blocking of ongoing calls due to the mobility of the users.
