In this paper, we introduced a design and implementation of a SIP signal control framework as a medium between the service logic and SIP stack. It is used to establish different kinds of RTP connections controlled by SIP application server according to the service logic. Through this framework, a new operation can be easily reused and a signal control flow can be easily modified or added by modifying...
We have witnessed the convergence of the telecom technologies and the Internet technologies recent years. Hybrid services combined with Internet service functionalities and telecommunication service functionalities have attracted much more attentions form both academic and industry communities. In this paper, we have proposed novel service creation architecture leverage on the so-called "web...
Multimedia conference is a real-time communication service for multiple parties, which involve audio, video, white board and so on. In this paper, we introduce a layered and component-based multimedia conference model based on JAIN SLEE Specification, and design the couple of subservices, such as create-conference, end-conference, modify-conference, change-chairman, and so forth. Finally, we implement...
This paper proposes an event-driven mechanism to semi-automatically realize the complex service composition using event-condition-action rules. Different from traditional composition methods for determining service operator, message, structure, event and provider orderly, ECA rule-based service composition method executes different actions according to condition when event emerges. Taking user requirement...
The value-added service (VAS) is one of the most important source of revenue for the telecommunication operators. With the convergence of the Internet and telecom network, VAS combined with Internet service functionalities and telecommunication service functionalities have attracted much more attentions from both academic and industrial communities. In this paper, we firstly give a quick survey on...
Gathering and understanding what the user need is one of the most important things in the service creation lifecycle. We firstly discuss the difference between the service requirements and the traditional software requirement. Then we propose the service requirement refinement method by decompose the goal of the users. Once the sub-goals are defined, they can be mapping directly into related service...
Development of services that span over the Internet and telecom networks is driving significant efforts towards the integrated of services offered by telecom operators. In this paper, we design and implementation of enhance state machine for telecom Web service considering the specific characteristics state, asynchronous, events driven communications in telecom domain. We focus on the design and implementation...
With the explosive growth of the Internet resources, Web search engines have become the most popular Web service to help people find relevant information on a given topic on the Web. However, many novice users have difficulty in formulating effective queries for their information needs, in the worst case, users are even not sure what exactly their specific information is. Under this condition, query...
Web Services makes network operators to accelerate the adoption of IT software concepts as service oriented architecture into the telecoms domain, which can reduce the time for value-added services to market. In this paper, we present an overview of the recent development in telecommunication area with a focus on key technologies that can be applied to Web service enablement of communication. In particular,...
Inspired by the success of Web service technologies for the development and deployment of IT services, the telecommunications R&D community starts adapting and developing similar service delivery platforms to catch the dynamic changing in Telecom market. In this paper, we propose a Web services communication model considering the specific features as asynchronous, event-driven communications in...
Various multimedia communication services are increasingly, recent advances of web service and service oriented architecture have made it possible for a Service-Oriented communication, which is a new development to integrate the communication for a business application in the Telecom industry. In this paper, we design and implementation the Service-Oriented multimedia conference process management,...
Inspired by the success of Web Service technologies for the development and deployment of IT services, the telecommunications R&D community starts adapting and developing similar service delivery platforms, making use of existing basic services as building blocks to orchestrate new value-added complex services in a rapid and flexible way to catch the fast and dynamic changing market. In this paper,...
The convergence of the Internet and telecom network changes the way we communicate in the daily life. Telecom operators and network vendors are trying to seek for a lower cost way to meet the constantly evolving market demands. In this paper, we propose a novel hybrid services orchestration framework based on semantic process template. Hybrid services are a set of services that combines the Internet...
Many Internet service developers already rely on the Parlay X to integrate telecom services to Internet applications. As a standard telecom gateway, Parlay X must be real-time, reliable and stable. In this paper, we consider the Parlay X and network elements as one system and a closed-queuing network model is proposed which has several characteristics such as finite-source, multiclass services and...
Business process execution language for Web services (BPEL4WS) has been proposed for composing Web services into a new one. A BPEL4WS description requires the specification of both the normal flow and the possible variations due to exceptional situations that can be anticipate and monitored. Nevertheless, defining exception handling is often in ad hoc way, it is up to the service developers to define...
QoS that defines service quality is an important criterion to differentiate Web services that have similar functions. In this paper, FQoS (feeling of QoS) model is proposed to model the quality of Web services in the view of users. And then the corresponding evaluation mechanism is present to automate measurement of the quality of Web services and maintain this information to provide them. Based on...
