An IP Multimedia Subsystem Services Proxy Gateway Based on a JAVA Dynamic Module System

Abstract

By virtue of the rapid development of the Information and Communication Technology (ICT), people have owned various devices connected to the Internet to enjoy various emerging application services, such as multimedia related services. IP Multimedia Subsystem (IMS) is the integration platform for multimedia application services and provides a rich feature set of converged services in the Next Generation Network (NGN). IMS services are accessed by a user anytime and anywhere through his/her personal self IMS device, e.g., mobile device, equipped with a Universal Subscriber Identity Module (USIM) card. People have owned various devices connected to the Internet at homes or offices. However, some devices can not access IMS services without USIM cards embedded, which is called non-IMS devices. People wish that more devices without USIM cards embedded should be connected to the Internet on which IMS services are accessed in addition to the mobile devices equipped with USIM cards. Accordingly, we propose an Open Service Gateway Initiative (OSGi)-based IMS service gateway, in which OSGi technology is the dynamic module system for JAVA. The proposed gateway is authorized by a personal self IMS device such that IMS services are accessed by non-IMS devices, in this paper. Moreover, these non-IMS devices rely on different networks to access technologies and network protocols and the IMS service gateway proposed here adopts the OSGi framework for no problem of integration.

Environmental Constraints for Intelligent Internet of Deep-Sea/Underwater Things Relying on Enterprise Architecture Approach

“…Therefore, because of the earlier validation procedure at the design phase, mistakes that may arise during the deployment phase are decreased if we ensure that these UECs are well respected throughout the design phase. Thus, there is a requirement for seamless integration between the MO information system and the communication system (e.g., IMS) [ 15 ].…”
