Lowering customer’s switching cost using B2B services for telecommunication companies

A B2B transaction is a transaction between organizations. However, the ripple effects of a B2B transaction can reach the members of the organization and generate additional economic impact. Enterprise LTE (Long term evolution) is a newly introduced B2B service in the South Korean telecommunications market. While it provides secure and fast telecommunications services to businesses, it can also affect the employees’ utility in the business, since the service provider can provide a variety of additional services to employees who use the same telecommunications provider for their mobile devices. In this study, we empirically analyze how B2B and Enterprise LTE services affect consumer churn-in in the telecommunications market. We estimate consumer benefit based on the additional services provided after the introduction of the B2B service using conjoint analysis. We also estimate consumer switching cost for changing one’s mobile telecommunications service provider using contingent valuation method. By comparing these values, we analyze the switching probability of employees when B2B services are introduced at their workplace. The results show that in order to maximize revenue, considering the revenue gained from new subscribers and from fees for providing additional services, lowering service fees for additional services and maximizing market share are advisable.     

Performance Evaluation of Protocols for Group-Oriented Mobile Services

The emerging mobile services, including m-commerce, have received considerable interest among researchers, developers, service providers, and users. Some of these mobile services require the support for group communications among mobile users for conducting transactions. Therefore, there is a need for protocols that are designed to support transactions for group-oriented mobile services especially under brief dis-connectivity and/or intermittent connectivity. In this paper, we identify the transaction requirements of group-oriented mobile services, present three protocol schemes and several new metrics for transactions, and evaluate the performance of protocol schemes under varying conditions. Our results show that higher levels of transaction completion probabilities and lower levels of transaction delays can be achieved to support the performance requirements of diverse group-oriented mobile services.

Composable Mediation for Security-Aware Mobile Services

This article shows how service mediation can be used to add security features to services in a mobile service platform. This base platform takes care of security, charging, and other basic functions, which are then configured for services at runtime using a pluggable mediator framework. Service providers can focus on content, and thus leverage the signaling and mediation capabilities of the core platform. Mediators add specific functionality to a service, and are a specific form of service composition and selection. We examine how security technologies for authentication and authorization are integrated by mediators into a single policy infrastructure with a homogeneous interface for services. We consider here the Web services SAML and the 3GPP GBA security bootstrapping standard in the context of mobile services. We give an example using a video on demand service, and discuss how and when security concerns of services can be transferred from the services to mediators.

Escrow techniques for mobile sales and inventory applications

We address the design of architectures and protocols for providing mobile users with integrated Personal Information Services and Applications (PISA), such as personalized news and financial information, and mobile database access. We present a system architecture for delivery of PISA based on replicated distributed servers connected to users via a personal communications services (PCS) network. The PISA architecture partitions the geographical coverage area into service areas, analogous to PCS registration areas, each of which is served by a single local server. When a user moves from one service area to another, the service is provided by the new local server. This is accomplished by a service handoff, analogous to a PCS call handoff, which entails some context information transfer from the old to the new server. We focus on the mobile sales and inventory application as an example of a PISA with a well‐defined market segment. We design a database management protocol for supporting both mobile and stationary salespersons. Our design uses the site‐transaction escrow method, thus allowing faster responses to mobile clients, minimizing the amount of context information which must be transferred during a service handoff, and allowing mobile clients to operate in disconnected mode by escrowing items on their local disks. We develop a formal model for reasoning about site‐transaction escrow, and develop a scheme for performing dynamic resource reconfiguration which avoids the need for time‐consuming and costly database synchronization operations (i.e., a two‐phase commit) when the mobile sales transaction completes. A further refinement to the scheme avoids an n‐way two‐phase commit during resource reconfiguration operations, replacing it with several simpler two‐phase commits. This revised version was published online in July 2006 with corrections to the Cover Date.     

Capacity optimizing channel allocation schemes for multi‐service cellular systems with mobile users

In this paper, we study the blocking and dropping probability of mobile users in the multi‐service cellular systems with mobile users. Based on the idea that different services may require different signal‐to‐interference ratios and different reuse factors, we proposed a channel allocation scheme called channel partitioning to support different services using different reuse factors. Under channel partitioning scheme, the channels in each cell are divided into two or more sets of channels and each set of the channels supports certain service, depending on the required reuse factor of the service. We first apply this channel partitioning with fixed channel allocation scheme called fixed channel partitioning (FCP), where a three‐dimensional Markov chain is developed to analyze the impact of the mobile user. After that a simpler model, which can estimate the numeric result from the closed‐form solution, is presented to make the analysis easier. In order to cater for the traffic variation between services and between cells, a dynamic channel partitioning with flexible channel combination scheme, called FDCP, is proposed to support multiple services. This FDCP tries to minimize the effect of assigned channels on the availability of channels for use in the interfering cells. The analysis and the simulation results show that for equal arrival rate of two services, the proposed FCP and FDCP scheme can provide about 32% and 54% improvement, respectively, in terms of grade of service as compared with conventional FCA scheme using a single reuse factor to support two services for the mobile users.

Mobile services put in context: A Q-sort analysis

Purpose

Objective of this paper to evaluate mobile services on a limited set of characteristics, e.g. usage context, the Innovativeness of the service, efforts required of users for using the service, the usefulness of the service and the likelihood with which it will be used, in order to show that distinction between services is highly relevant for adoption and acceptance research.

Design/method/approach

In this research the mobile services are object of study and therefore an exploratory approach making use of Q-sort methodology is used.

Findings

The characteristics of the 48 services under study play an important role when judged on the five dimensions. Advanced services, explicitly exploiting the mobile nature of the services like navigation and localization, embedded in all kind of task and process related activities, stood out as the most innovative services, however these are the least likely to be used because they are expected to fit day-to-day routines and usage context the least. Easy to use services and services that fit most contexts are most likely to be used.

Practical implications

Designers of mobile services and applications have to be aware of the subtle interplay between usage context, the service or application to be designed, the ease of use. Only when all these factors are taken into account the services may have value to users.

Original value

This is one of the very few studies focused on mobile services, instead of user perception and behavior. In most research on mobile service adoption and acceptance the characteristics of services are threatened as a black box. This paper shows how relevant it is to look into characteristics of mobile services themselves.     

Content and Service Protection for the Ubiquitous TV Based on Network Convergence

Today, the ubiquitous multimedia services are becoming more and more popular. However, the secure solutions that confirm the content and service security in these services are still open issues because of various network convergences and device interconnections. This paper investigates an ubiquitous multimedia service architecture and proposes a secure solution for it. In this service architecture, the multimedia content is encoded with scalable video coding and broadcasted via digital video broadcasting for handheld terminals (DVB-H) to mobile terminals, the access right is transmitted by global system for mobile (GSM/GPRS) channel, and the media content and access right can also be transferred from mobile terminals to home TV through WiFi based Wireless Local Area Network. The proposed secure solution supports three kinds of business models by using various content encryption modes and secure transmission protocols. The solution’s security is evaluated and discussed. Since few work has been done to solve this problem, the work proposed in this paper is expected to attract more researchers. Additionally, the solution is also potential for other ubiquitous services.     

Building a Platform to Bridge Low End Mobile Phones and Cloud Computing Services

Two waves of technology are dramatically changing daily life: cloud computing and mobile phones. New cloud computing services such as webmail and content rich data search have emerged. However, in order to use these services, a mobile phone must be able to run new applications and handle high network bandwidth. Worldwide, about 3.45 billion mobile phones are low end phones;they have low bandwidth and cannot run new applications. Because of this technology gap, most mobile users are unable to experience cloud computing services with their thumbs. In this paper, a novel platform, Thumb-in-Cloud, is proposed to bridge this gap.Thumb-in-Cloud consists of two subsystems: Thumb-Machine and Thumb-Gateways. Thumb-Machine is a virtual machine built into a low end phone to enable it to run new applications. Thumb-Gateways can tailor cloud computing services by reformatting and compressing the service to fit the phone' s profile.
