In this paper a practical architecture for creation of OSA ParlayX Gateway in service layer of an integrated networks, according to IMS architecture will be presented. OSA ParlayX Gateway is a suitable platform for third party operators participation to provide integrated services in NGN. Third parties without any knowledge of network technologies, by using standard ParlayX APIs on top of Web Services...
A technical prerequisite for a converged network is a common service delivery platform that is independent from the access networks below. The 3GPP SIP-based IP multimedia subsystem (IMS) is defined for this purpose. By specification, IMS is the first implementation towards reaching converged communications which allows users to communicate with video, audio and multimedia content, via any fixed,...
In this paper a structure for providing and offering service in NGN network is proposed. This structure, which is named application server, is a specified unit and it is not a tool. Actually, an application server is a set of different parameters providing connection between various parts, which are dealing to network problems, such as third parties, developers and etc. This structure is designed...
Nowadays using Presence and IM (Instance Messaging) services in communication (voice, video and text) especially in real time communication is so popular and has a great position in telecommunication world; so many people use Messengers. In this paper, we will revise the functionality of these services; meanwhile, we will study the protocols which are used in implementing IMP services in Yahoo Messenger...
Next generation networks with the intention of different Access network Convergence in Control and Service Layer, Introduce an integrated network. At Convergence point, various IT and telecom Services are offered to different network users by these networks. In this convergence, a suitable infrastructure should also be prepared so that new services can be created and provided by telecom and IT service...
Next generation networks with the idea of convergence of service and control layer in existing networks (fixed, mobile and data) and with the intention of providing services in an integrated network, has opened new horizon for telecom operators. On the other hand, economic problems has caused operators to look for new source of income including consider new services, subscription of more users and...
In this work, domino logic with a latched keeper technique is proposed. The circuit, which is used to implement the technique, utilizes a latch with standard domino. By using the simple structure, we can obtain better performance, noise immunity, and lower power consumption. The simulation results for a 65 nm CMOS technology show an improvement between 5% and 55.7% in delay and 8% and 15% in power...
