the goal of this paper is to compile strategies for a chinese international telecommunication vendor which entered into iran telecom market in the year 2000. since zte is involved with business in more than 135 countries and it is out of our power to collect huge data from all over the world, we have limited our strategies to iranian market and we will compile strategies for iran business unit...

While the notion of a Distributed DBMS has been familiar to the IT industry for several decades, within telecom networks the subscriber data management based on DDBMS technology is a novel addition to a service provider's infrastructure. Service providers are used to telecom networks that are efficient, reliable and easy to maintain and operate, in part thanks to the node model used in designin...

An extension of the non local (NL) means is proposed for images damaged by Poisson noise. The proposed method is guided by the noisy image and a pre-filtered image and is adapted to the statistics of Poisson noise. The influence of both images can be tuned using two filtering parameters. We propose an automatic setting to select these parameters based on estimated mean square error (MSE) minimi...

Website www.icra.in The Indian telecom industry has witnessed significant growth in subscriber base over the last decade, with increasing network coverage and a competition-induced decline in tariffs playing facilitators. The growth story and the potential have also served to attract newer players in the industry, with the result that the intensity of competition has kept increasing, forcing th...

for effective crisis management, appropriate telecommunications, which are required to fast response, are crucial. therefore, lack of existing proper telecommunications detract senior managers’ awareness about crisis conditions and also disturb rescuers in relief, causing increasing attendance time to the injured and fatalities. transfer point location problem is one of the new issues in the li...

With the rapid growth of telecom sector heading towards 5G and 6G emergence high-bandwidth time-sensitive applications, mobile network operators (MNOs) are driven to plan their networks meet these new requirements in a cost-effective manner. The cloud radio access (CRAN) has been presented as promising architecture that can decrease capital expenditures (Capex) operating (Opex) improve performa...

In current market scenarios, telecom companies are quite competitive and look forward to have lion’s share in the market by winning new and withholding existing customers. Customers who are lost to competitor are known as Churned customers and can be retain by adopting Churn prevention model. For a given dataset, this model predicts the list of customers to be churned in future enabling the res...

High-bit-rate nanocavity-based single photon sources in the 1,550-nm telecom band are challenges facing the development of fibre-based long-haul quantum communication networks. Here we report a very fast single photon source in the 1,550-nm telecom band, which is achieved by a large Purcell enhancement that results from the coupling of a single InAs quantum dot and an InP photonic crystal nanoc...
