With the advancement of Internet technologies and the widespread use of mobile devices, the number of users in conferencing services is increasing quickly. A P2PSIP conferencing system and an IP Multimedia Subsystem (IMS) conferencing system have been designed to provide conferencing services. The IMS conferencing system was developed to adapt to a server-based centralized system, while the P2P network,...
Mobile users' demand for using the best available network connection encourages mobile network operators (MNOs) to construct multi-access networks managed by all-IP based mobile networks. For such an MNO, the IP Multimedia Subsystem (IMS) is a promising service control infrastructure to provide IP-based multimedia services with QoS guarantee in the multi-access network. The service centralization...
The rapid growth of the access technologies provides an opportunity for appropriately equipped user terminals to access the rich communication suite services. And the IP Multimedia Subsystem (IMS) could very well be the best solution for most operators. The more recent releases have included interfaces to non-IP Capable Access Network (IP-CAN) as well as IP-CAN. In addition to, a Mobile VoIP (mVoIP)...
Recently, femtocells, which cover a cell area of several tens of meters, have been attracting considerable attention in mobile communications. When a femtocell is connected through a public network, such as a broadband access network or the Internet, a secure tunnel is established between the femtocell and the security gateway located in the mobile core network and media data are sent and received...
The present paper describes practical experience gained with IMS based fixed mobile convergence (FMC) network deployment at TDC Denmark. The paper also takes a look into the near future, showing trend in technology. This network deployment, including the FMC component, is a joint project between TDC Denmark and Ericsson. The FMC implementation offers advanced services to enterprise users. Enterprise...
Today telecom operators vision is rapidly moving towards next generation networks (NGN) that offer ubiquitous converged services over converged networks. Fixed-mobile convergence (FMC), is the convergence of mobile and fixed (or wire line) telecommunications services, terminal devices, and networks. The convergence of fixed and mobile services is an evolution from both the technological and marketing...
Integrating telecom services to a standard service delivery platform reusing its standard interfaces to communicate with other services makes both deployment and operation cheaper and easier. That makes it necessary to integrate the state of the art technologies like OMA Converged IP Messaging (CPM) with a standard All-IP service delivery platform like IMS. This work focused on the yet to be explored...
The IP multimedia subsystem (IMS) could very well be the best solution for most telecom operators. The more recent releases have included interfaces to fixed line networks and wireless LANs. This has consequences both for the migration of the core network as well as the integration of future mobile services and applications. Also, an interworking between IMS providers is considered to be a major step...
Today's world has been changing drastically over few past years in aspect of telecommunication technology development. World has become a small village, connected via large variety of media and devices. With grow of telecommunication industry popularity a need of Internet-mobile-fixed convergence has grown to be a significant issue to be considered and implemented. The matter is important as combining...
In this paper, the author describes the design and implementation of a LDNA (Digtal Living Network Alliance) Framework for Handheld devices. DLNA has developed guidelines for interoperability among home devices enabling a multitude of usage scenarios for sharing digital content such as A V (Audio Visual), Photo, and Audio. The proposed DLNA (Digital Living Network Alliance) Client Framework handles...
