The integration of the telephone network and the internet enables convergence of voice and data services. The explosion of information appliances also provides new service opportunities. Object-oriented systems show great promise for building new classes of services that dynamically adapt to changing networks and appliances. This paper describes how we use migratory objects to build new classes...

the hierarchical hub location problem is encountered three-level network that is applied in production-distribution system, education system, emergency medical services, telecommunication network, etc. this paper addresses the hierarchical hub covering problem with single assignment accounting for mandatory dispersion of central hubs restriction as a special case. this formulation with incorpor...

Network is the bearer of services and services are the soul of network. The convergent network extends the original communications service type and gradually forms new convergent services which integrate the traditional telecommunication services and a large number of value-added services or contents on Internet (Kolberg et al., 2010). The integrated service is essentially to handle the data an...

This paper describes the tools and techniques being applied in the TINA Open Service Creation Architecture (TOSCA) project to develop object-oriented models of distributed telecommunication services in SDL. The paper also describes the way in which Tree and Tabular Combined Notation (TTCN) test cases are derived from these models and subsequently executed against the CORBA-based implementations...

Abstract Value-Added Services at a Mobile Telecommunication company provide customers with variety of services. Value-added services generate significant revenue annually for telecommunication companies. Providing solutions that can relevant and engaging has become major challenge in this field. Numerous methods have been proposed so far to analyze customer basket related Although these many ap...

Meshing up telecommunication and IT resources seems to be the real challenge for supporting the evolution towards the next generation of Web Services. In telecom world, JAIN-SLEE (JAIN Service Logic Execution Environment) is an emerging standard specification for Java service platforms targeted to host value added services, composed of telecom and IT services.In this paper we describe StarSLEE ...

During the past decade, the telecommunication environment has evolved from single operator featuring voice services to multi-operator featuring a range of different types of services. Services are being provided today in a distributed manner in a connectionless environment requiring cooperation of several components and actors. This paper focuses on the incremental means to ensure access to ser...
