Mobile Agents For Supporting Ubiquity In Telecommunication Services
Lanoms 2001 - 2nd Latin American Network Operations And Management Symposium, Proceedings. Universidade Federal Do Rio De Janeiro, v. , n. , p. 50 - 61, 2001.
Telecommunications have had a strong impact on the society in the last decades. Nowadays, this role is ever increasing and pushing the technological and economic evolution of our society. The evolution of telecommunications creates new services that exploit the convergence between data communication, computation and entertainment. In this context, we are interested in service portability and adaptability as a result of personal mobility a concept known as VHK (Virtual Home Knvironment). In the specification and development of this new generation of services, which incorporate VHK in some extent, object orientation, component reuse, open distributed systems, and service architectures are words of order. Among these specifications we can emphasize TINA (Telecommunication Information Network Architecture). Moreover, architectures based on mobile and intelligent agents may open new, efficient, and flexible ways to distribute control and management for this new generation of telecommunication systems. In this article, we propose a service architecture that preserves the positive aspects of TINA and relies on de facto open standards (e.g., the Internet) and mobile agents for supporting service and personal mobility. In order to evaluate the proposed architecture with respect to personal and service mobility, a prototype of a multimedia service was implemented.5061Clark, D., Pasquale, J., Strategic Direction In Networks and Telecommunications (1996) ACM Computing Surveys, 28 (4). , DecemberService Creation on a TINA Platform: An Experience Report (1997) TINA'97 Conference, pp. 78-86. , Lorenz Lehmann, Mauro Cadorin e Claude Eric Wurgler, Santiago, Chile, NovemberBerndt, H., The TINA Book (1999) Prentice Hall Europe(1999) Service Aspects: Virtual Home Environment, , UMTS, UMTS Forum Report 22.70 Version 3.0, Universal Mobile Telecommunications SystemPinto, A.S., Oliveira, E.J., Faina, L.F., Cardozo, E., A TINA- based Environment for Mobile Multimedia Services (1999) TINA '99 Conference, pp. 54-65. , Oahu, Hawaii, USA, April(1999) The Common Object Request Broker: Architecture and Specification Version 2.3.1, , http://www.omg.org, OMG, Document formal/99-10-07, Object, Management Group, October(2000) JamrM 2 Software Development Kit, , http://www.java.sun.com/products/, Sun Microsystems(1997) Voyager Core Technology, , http://www.objectspace.com, Object Space., Technical Overview Version 1.0, Object Space, Inc., December(2000), http://www.omg.org, OMG.
