The competition among mobile network operators in the telecommunication supply chain

In the mobile telecommunication sector, the high competitiveness has increased the complexity of strategic interactions among operators. As the vertical integration has become anything but a choice and not a compelling technical solution, the contest takes place at different levels of the components of the operator value chain: the network infrastructure, the service development and supply, and the relationship with consumers.Mobile virtual network operators act as retailers and concentrate on the last segment of the value chain by establishing commercial agreements with hosting network operators, which act as manufacturers, to get access to radio communications infrastructure. Productive processes of mobile services offered by operators are different and this difference is imperceptible to customers. Processes difference mainly consists in the infrastructural diversity of the operators and implies different consequences on each network service element.A model has been defined to analyze the consequences of such diversity in the competition among HNOs, MNOs, and MVNOs by focusing the attention on the characteristics of the call path, in dependence of the types of operators. In fact, many variables interact to define the call path, such as marginal costs and revenues, infrastructural investments, and interconnection charges among operators. The analysis of the results, obtained by the model, gives information on variations of retail prices, market shares, and profit allotment, to adopt the proper strategies. In particular, the model results shed light on how certain MVNOs should enter the markets and adopt a collaborative strategy with HNOs. The model owns the capability of being applied to different contexts, thus representing for the regulator a potential instrument of relevant usefulness.     

大容量GPRS-HLR系统中内存数据库的数据结构组织模式

在移动通信系统中,为了满足HLR系统移动应用部分（MAP）对事务处理的实时需求,需要采用内存数据库供协议处理。同时为了提高HLR系统的容量以及数据的安全与完备性,需要采用高性能商用数据库管理系统。在设计中我们将内存数据库视作商用数据库的缓存以满足HLR系统大容量、高实时性以及高可靠性要求。文中给出了用于大容量HLR系统的内存数据库的数据结构组织模式与设计方案。     

流动人口对城乡移动通信扩散的影响机制研究

本文从微观个体的角度,证实网络效应在我国城乡移动通信扩散过程中的作用,揭示流动人口在城乡之间发挥传导作用并影响城乡移动通信扩散差距的内在机制.研究结果发现,网络效应对城乡移动通信扩散均发挥显著的正向作用,且城市地区的网络效应大于农村地区;城市强网络效应促使移动电话在流动人口群体内加速扩散,使流动人口的网络效应增强;移动电话在流动人口群体内的扩散对农村移动通信扩散具有促进作用,表现为与亲人之间联络产生的直接效应和通过增加农村安装基础产生的间接效应.流动人口在城乡群体之间发挥传导作用,最终使城乡移动通信扩散的差距得以缩小.

Unlocking the promise of mobile value-added services by applying new collaborative business models

Due to the intense voice service competition and subscriber growth saturation, the average revenue per user (ARPU) of mobile communications service providers continues to decline, thereby severely affecting their total revenue and profitability. To counter this challenge, mobile communications service providers are now moving from “tariff competition” to “service competition.” As mobile communications enter the next-generation network (NGN) era, network bandwidth and transmission speed are greatly enhanced. The enhancement enables mobile communications service providers to provide content-rich, multimedia value-added services to create new service value, meet demands of customers, and increase ARPU. To understand how to construct mobile value-added services, this study uses survey forms to collect feedback from 35 industry and research institution experts and scholars and to present systematically the finding on the mobile value-added services strategy. The research employs the analytic network process (ANP) to analyze the strategy of mobile service providers in delivering mobile services in the NGN. The business strategy evaluation framework and evaluation result can be used as guides for players in the mobile communications industry to review, improve, and enhance their service and strategy.     

Idea generation leveraged from value co-creation process enhances new service development performance

This study examines the relationship between value co-creation process, idea generation and new service development performance from the perspective of telecommunication companies. Two dimensions of idea generation tested in this framework are internal and external idea generation, and the probable relationship between these two dimensions is further investigated. The data were collected from 78 marketing managers and were statistically analyzed. The findings show that value co-creation crucially influences both external idea generation and internal idea generation, however, the new service development performance can be enhanced through internal idea generation. Nonetheless, the results show that the external idea generation is vital to influence internal idea generation. This study extends theoretical understanding of how to leverage the value co-creation process for idea generation happenings, while the practical contribution of the research is to realize that new service development performance demands internal idea generation, which is supported with external resources of idea generation.     

Do mobile banner ads increase sales? Yes,in the offline channel

Firms allocate increasingly large budgets to mobile banner advertising. Yet, existing research paid only scant attention to the sales effects of mobile banner ads. In this paper, we fill this gap by determining the offline and online sales impact of a large-scale mobile banner advertising campaign. As part of a geographical field experiment, over 3.5 million mobile banner ads were served to a predetermined geographical area. We determine the offline and online sales effects of the mobile banner ad campaign by analyzing twenty months of sales data for regions covering the entire country of the Netherlands. Relying on a difference-in-difference approach and two matching methods, we demonstrate an offline sales increase of around 2%. The online sales effect is not significant. We conclude that firms can use mobile banner advertising to boost offline sales. We find no evidence for cross-channel sales cannibalization.     

Telephone Penetration and Economic Growth in the APEC Region: A Simultaneous Non-Linear GMM Approach

We examine the contributions of the telecommunications infrastructure to economic growth in the Asia-Pacific Economic Cooperation (APEC) economies during the period from 1982 to 2003 using a modified version of the model developed by Roller and Waverman (2001). Our estimation results show that, consistent with Roller and Waverman (2001), telecommunication infrastructure has a significant effect on economic growth in the APEC region and that the inclusion of country fixed effects is important for obtaining a more reliable estimate of the growth effect. Moreover, the magnitude of the growth effect is inversely related to the level of telecommunications infrastructure in the APEC economies. While the marginal effect of an increase in telecommunications infrastructure in the APEC region is smaller than that in the OECD countries found in Roller and Waverman (2001), the total contribution of telecommunication infrastructure to economic growth is larger in the former than in the latter.
