基于IP分布式MSC的CDMA2000系统A接口设计与实现

针对传统集中式移动交换中心(MSC)容量小、安全性低、不易扩展的不足,基于IP技术和软交换技术,提出了一种分布式MSC架构.在此架构下对A接口协议进行了分析并给出了基于IP的实现方案:兼顾TCP的可靠性和UDP的简洁性定义了承载A接口中的信令和业务的一个增强性UDP协议(EUDP).此外,也描述了分布式MSC负荷分担的选择原则:轮选、处理最近和资源最近;最后以8 kbit/s语音业务为例,对基于IP传输语音业务的带宽需求进行了简单分析.实践表明,该方案不仅提高了系统的经济性,也改善了网络容量扩展和新业务提供的灵活性.

Breaking new ground: base-of-pyramid service research

Two-thirds of the world's population lives in poverty, a global problem that researchers from a wide variety of disciplines study. Yet there is a fundamental lack of service research pertaining to this huge segment of society, commonly known as the base of the pyramid. This segment offers a rich source of information that could help break new ground in service research, by exploring services in contexts in which its current concepts, models, theories, and generalizations might not apply the same way. This article starts by exploring key contributions in base of the pyramid literature and identifying the main perspectives from which extant knowledge has developed. By revising existing service research priorities to identify useful intersections with base of the pyramid perspectives, this study offers new grounds deriving five research streams that reflect the integration of base of the pyramid research perspectives with service research priorities. Finally, this article details the emerging area of base of the pyramid service research using one of those research priorities, namely, transformative service research, in an effort to specify the relevant objectives, scopes, differences, and similarities and thereby identify common grounds for future service research at the base of the pyramid.     

Effects of Network Embeddedness on the Relationship Between Environmental Volatility and Interfirm Contracts

Purpose: This study examines the effects of an embedded network on the contractual relationship between exchange parties under conditions reflecting varying levels of environmental volatility and investigates the role of an important network factor—the embedded network—in the contractual relationship between manufacturers and their suppliers.

Methodology: The empirical test was conducted with manufacturing companies in the context of manufacturer–supplier relationships. Construct measures were based on existing measures and previous research. Measurement reliability and validity were established using exploratory and confirmatory factor analysis and an overall measurement model was assessed with structural equation modeling using LISREL.

Findings: The results of a survey of manufacturers indicate that firms in an embedded network preferred “soft” contracts even when they face volatile environments, whereas those facing volatile environments in a less embedded network preferred “hard” contracts with explicitly specified written requirements. Network partners carefully evaluated embedded networks (a critical factor that has not received enough attention) before forming contractual relationships in a network perceiving interfirm relationships differently.

Originality: The study introduces network embeddedness to explain governance mechanisms in volatile environments and shows that the explicit recognition of embedded network may facilitate the development of contracts with specific provisions as the contractual relationship evolves.     

A safe speed guidance model for highways

ABSTRACT

This paper presents a fuzzy logic model to support decisions for the suggested speed limit for sections of highways as they become affected by adverse road conditions, environmental factors and differing traffic levels. The definition of the main factors, and their weight, that reduce safety on highways was conducted by the Delphi method, consulting traffic engineering experts. The survey served as a basis for structuring indicators and indexes in a soft decision tree, structured by a fuzzy logic system. The system can be used to support the decisions of those that manage the roads, indicating to drivers’ speeds, by visual, audible or combined systems.
