A convergent service is defined as a service that exploits the convergence of communication networks and at the same time takes advantage of features of the Web. Nowadays, building up a convergent service is not trivial, because although there are significant approaches that aim to automate the service composition at different levels in the Web and Telecom domains, selecting the most appropriate approach for specific case studies is complex due to the big amount of involved information and the lack of technical considerations. Thus, in this paper, we identify the relevant phases for convergent service composition and explore the existing approaches and their associated technologies for automating each phase. For each technology, the maturity and results are analysed, as well as the elements that must be considered prior to their application in real scenarios. Furthermore, we provide research directions related to the convergent service composition phases.

“…Por últi-mo, IMS también ofrece características como la seguridad y calidad de servicio por lo que es una plataforma de servicio perfecto y completo de las NGN. [6]. Existen varios componentes claves del núcleo central de IMS que está basado en la sesión de llamadas con las funciones de control (CSCF, es decir, P-CSCF, S-CSCF y I-CSCF) y de un HSS, como se muestra en la Figura 1.…”

“…El cual extrae el paquete original del paquete MIPV6 recibido y se lo envía al CN (5). Si el CN tiene soporte IPV6, entonces IPV6 en el momento de estar en la red visitada es la CoA y no la HoA, de tal forma que el CN envía los paquetes de datos directamente a la CoA del nodo móvil (6). A todo este proceso se le denomina Route Optimization y es una mejora en el camino seguido por los paquetes puesto que no tienen que pasar por el HA, lo cual introduce retardos innecesarios.…”

Abstract-With the merging of IP and TelCo networks, Mobile-to-Mobile (M2M) social networks are to be unfolded as an ultimate telecom business in the near future. By M2M, both service provider and service client are aimed to be mobile based. Hence considering mobile devices to be resource constrained and mobile networks as low-bandwidth networks, provisioning high-profile multimedia services is not somewhat straight forward. The Quality of Service (QoS) has always been a great concern in this scenario. Additionally in M2M service networks, the direct IP accessibility of mobile devices is a bottleneck in seamless communication. The cellular operators typically block every incoming http access to subscribers devices inside and outside the network due to huge traffic load and security reasons.The paper addresses the issues faced in M2M service networks and presents a solution based on the IP Multimedia Subsystem (IMS). Similar to SIP Application Servers (AS) in the IMS network, the concept of Mobile Application Servers (Mob-AS) is introduced in order to host and execute multimedia services from a mobile device. A comprehensive design of Mob-AS is presented based on the existing REST interfaced synchronous and asynchronous mobile server framework.Index Terms-M2M social networks, mobile application server, quality of service, synchronous, asynchronous.
