the ties that bind the role of migrants in the uneven geography of international Telephone Traffic
Global Networks-a Journal of Transnational Affairs, 2013Co-Authors: Richard Perkins, Eric NeumayerAbstract:Recent work suggests that migrants have been a major driving force in the dramatic growth of international telephony over recent decades, accounting for large rises in Telephone calls between countries with strong immigrant/emigrant connections. Yet, the existing literature has done a poor job of evaluating the substantive importance of migrants in explaining large disparities in levels of bilateral voice Traffic observed between different countries. It has also failed to go very far in examining how domestic and relational factors moderate (namely amplify or attenuate) the influence of migrant stocks on international calling. Our contribution addresses these gaps in the literature. For a sample, which includes a far larger number of countries than previous studies, we show that, together with shorter-term visitors, bilateral migrant stocks emerge as the relational variable with one of the substantively largest influences over cross-national patterns of Telephone calls. We also find that the effect of bilateral migrant stocks on inter-country Telephone Traffic is greater where the country pairs are richer and more spatially distant from one another.

the ties that bind the role of migrants in the uneven geography of international Telephone Traffic
Social Science Research Network, 2010Co-Authors: Richard Perkins, Eric NeumayerAbstract:Recent work has suggested that migrants have been a major driving force in the dramatic growth of international telephony over recent decades, accounting for large rises in Telephone calls between countries with strong immigrant/emigrant connections. Yet the existing literature has not done a good job of evaluating the substantive importance of migrants in explaining large disparities in levels of bilateral voice Traffic observed between different countries. Nor has it gone very far in examining how the influence of migrant stocks on international calling is moderated (i.e. amplified or attenuated) by domestic and relational factors. Our contribution in the present article addresses these gaps in the literature.

Cheap Calls: The Social Glue of Migrant Transnationalism
Global Networks, 2004Co-Authors: Steven VertovecAbstract:Abstract Although globalization has usually been associated with advanced communications technology, arguably nothing has facilitated global linkage more than the boom in ordinary, cheap international Telephone calls. Low-cost calls serve as a kind of social glue connecting small-scale social formations across the globe. In this article I present recent data on the rapid growth and diffusion of Telephone Traffic and describe the proliferation of prepaid phonecards. Second, I outline the commercial, social and geographical ramifications of this explosion in transnational communication.

an empirical study on time correlation of gsm Telephone Traffic
IEEE Transactions on Wireless Communications, 2008Co-Authors: Stefano Bregni, R Cioffi, Maurizio DecinaAbstract:In this paper, we investigate possible time correlation of answered call arrivals in sets of real GSM Telephone Traffic data. Instead of attempting to model the empirical distribution of the call interarrival time, as done in several previous works in literature, we emphasize results obtained by the modified Allan variance (MAVAR), a widely used time-domain quantity with excellent capability of discriminating power-law noise types. The call arrival rate exhibits a diurnal trend, with peak hours in the morning and late afternoon. Besides this diurnal rate change, the number of call arrivals in a second is found perfectly uncorrelated to the number of arrivals in other seconds and Poisson distributed, with good consistency by X/sup 2/- test evaluation. Uniform and accurate whiteness of call arrivals per second is verified in all hours, regardless the time of the day. In all series analyzed, the empirical statistics of both originated and terminated call arrivals proves excellent consistency with the ideal Poisson model with diurnal variable rate lambda(t). This study may be valuable to researchers concerned about realistic Traffic modelling in planning and performance evaluation of cellular networks.

separable routing a scheme for state dependent routing of circuit switched Telephone Traffic
Annals of Operations Research, 1992Co-Authors: Teunis J Ott, K R KrishnanAbstract:Separable routing is the first of a number of routing schemes for circuit switched Telephone Traffic invented at Bellcore. These routing schemes are state dependent, in the sense that, for each call attempt, a routing decision is made on the basis of the state of the network (defined in terms of the numbers of busy and idle trunks in the various trunk groups at the moment of the call attempt). In this paper, we describe separable routing and its mathematical background. Simulation results we have presented elsewhere show that the family of state-dependent routing schemes, of which separable routing is a member, is very attractive in terms of blocking rate, built-in network management features, and behavior in the presence of Traffic forecast error.
