Channel assigning scheme study in LEO constellation communication system combining handover reserving strategy and new call queuing

open access: yesTongxin xuebao, 2006
A channel assigning scheme which was adapted to LEO constellation communication system was proposed. The scheme provided reserved channel for handover call to reduce blocking probability of handoff call.Meanwhile, new call queuing strategy was adopted to

Approximate analysis of non-stationary loss queues and networks of loss queues with general service time distributions [PDF]

open access: yes, 2011
A Fixed Point Approximation (FPA) method has recently been suggested for non-stationary analysis of loss queues and networks of loss queues with Exponential service times.

Approximations for Call-Blocking Probabilities in Multirouting Multicasting Multirate Loss Networks [PDF]

open access: yes, 2000
For the end-to-end call blocking probability computation in multi-rate loss networks the so called reduced load approximation under link independence assumption is often used, because it allows derivation of analytical results. However, its accuracy and extendibility to multirouting or multicasting networks (like the B-ISDN) is seldom studied.

An Erlang multirate loss model supporting elastic traffic under the threshold policy

open access: yes, 2015
In this paper, we propose a multirate teletraffic loss model of a single link with certain bandwidth capacity that accommodates Poisson arriving calls, which can tolerate bandwidth compression (elastic traffic), under the threshold policy.

A New Proposed Algorithm for the Priority of the Cellular Calls [PDF]

open access: yesEngineering and Technology Journal, 2012
There are many criteria for managing the priority in calling queues. The purpose of our work is to make a balance between two conflicting requirements: maximize the resource utilization and minimize the forced handover call dropping rate.

Modeling and simulation of call centers.

open access: yes, 2006
In this review, we introduce key notions and describe the decision problems commonly encountered in call center management. Main themes are the central role of uncertainty throughout the decision hierarchy and the many operational complexities and ...

Analysis of loss probabilities on the call level and packet level in a multi-rate system

open access: yesTongxin xuebao, 2007
A systematic research on the performance analysis on the call level and the packet level in a system with multi-rate VBR services was made.According to the global balance condition of a multi-dimensional Markov chain,an algorithm of accurately evaluating

Performance analysis of a handoff scheme for two-tier cellular CDMA networks

open access: yesEgyptian Informatics Journal, 2011
A two-tier model is used in cellular networks to improve the Quality of Service (QoS), namely to reduce the blocking probability of new calls and the forced termination probability of ongoing calls.

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

open access: yesMolecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Traffic savings through a cac procedure incorporating a fair bandwidth allocation policy for elastic services

open access: yesCommunications, 2004
We apply the max-min fairness policy (MMF) for elastic services with min and max bandwidth requirements (approximated MMF) not to a single link but to a whole connection-oriented network.
