Call Blocking Probability and Effective Throughput for Call Admission Control of CoMP Joint Transmission

IEEE Transactions on Vehicular Technology, 2016
Coordinated multipoint transmission (CoMP) with the joint transmission (JT) scheme is employed in cellular networks to improve data rate and cell-edge throughput and/or to increase system throughput. In CoMP-JT, since the user equipment (UE) is capable of receiving the desired signal from an adjacent cell, as well as from its serving cell, it can ...

A unified approach for evaluating call blocking and burst blocking in high speed networks

Proceedings 1995 Canadian Conference on Electrical and Computer Engineering, 2002
We resent a network dimensioning method for supporting multimedia services in high speed ATM networks with the required guarantee on the QOS at the call level and burst level simultaneously. The different multimedia traffic calls arrive according to a Poisson process and their holding time is exponentially distributed.

On Call Blocking Probabilities and Resource Utilization in OFDM Wireless Networks

2018 11th International Symposium on Communication Systems, Networks & Digital Signal Processing (CSNDSP), 2018
In this paper we consider the downlink of an Orthogonal Frequency Division Multiplexing (OFDM) based cell that accommodates Poisson arriving calls generated from different service-classes and having different traffic description parameters. The system is modelled as a multirate loss model.

Connection splitting: an efficient way of reducing call blocking in ATM

IEEE/ACM Transactions on Networking, 2000
In this paper, we propose a technique for reducing asynchronous transfer mode (ATM) call blocking which is achieved by splitting wide-band connections into multiple low-bandwidth subconnections and routing them independently through the network. The essence of the mechanism is to use fragmented network bandwidth for supporting calls which are otherwise

Reducing handoff call blocking probability by hybrid channel allocation

Proceedings of the 2011 International Conference on Communication, Computing & Security - ICCCS '11, 2011
In cellular networks, handoff is the mechanism that transfers an on going call from the current cell to the next cell as the Mobile Unit (MU) moves through the coverage area of the cellular system. A handoff procedure results in a call termination in the current cell along with a call arrival in the destination cell.

A new handoff scheme for decreasing both dropped calls and blocked calls in CDMA system

EUROCON'2001. International Conference on Trends in Communications. Technical Program, Proceedings (Cat. No.01EX439), 2002
Soft handoff in the CDMA cellular system is analyzed. To improve performance degradation due to channel resource shortage during soft handoff, we propose a new scheme which converts channels occupied by some pseudo-handoff calls to new handoff calls. Stochastic reward net (SRN) models for our scheme are constructed and solved by SPNP (Stochastic Petri ...

Resource allocation and call blocking in mobility network architectures

1999 IEEE 49th Vehicular Technology Conference (Cat. No.99CH36363), 2003
This paper investigates the effects of mobility on the resource allocation and call blocking in mobility network architectures. On the basis of a stochastic analytical framework, we determine the probability distribution of the number of radio links used within the cell as a function of all the mobility related parameters (viz.

THE NATURE OF SO-CALLED SINO-AURICULAR BLOCK

Archives of Internal Medicine, 1925
Sino-auricular block is a term applied to a relatively uncommon arrhythmia in which, in an otherwise regular rhythm, dropped beats occur, both auricular and ventricular beats participating in the intermittence. This definition is not strictly true because sino-auricular block is frequently associated with sinus arrhythmia.

Call Blocking in Spectrally Constrained FDMA/DAMA SATCOM Systems

IEEE Transactions on Communications, 1979
A problem in the use of satellite Demand-Assigned Multiple Access (DAMA) results from spectrum limitations at each ground terminal due to avoiding frequency interference to nearby terrestrial microwave radio relay. Frequency Division Multiple Access (FDMA/DAMA) can operate with a terminal-by-terminal assignment of frequency channels out of the total ...
