the aim of this research is to prioritize the key factors for implementation of idea virtual bank (ivb) in telecommunication industry. the current applied and descriptive research was conducted based on a survey. the population of this research consisted of all users of ivb and idea submitters to suggestion system of telecommunication industry in province of razavi-khorasan that 70 of them were...

The Intelligent Network (IN) concept, proposed by the International Telecommunication Union (ITU), represents an approach to deal with the growing demand for complex services in communication networks. Major advantages of this concept are easy service creation, independence of vendor-speciic equipment, and an economical distribution of service functionality within the network. Dedicated signall...

In the field of telecommunication, to deliver high quality and low cost multimedia services to users is indeed a milestone. Next Generation Network (NGN) is an IP network which facilitates researcher to achieve this milestone. IP Multimedia Sub-system (IMS) makes possible to deliver IP multimedia services to users. IMS uses Session Initiation Protocol (SIP) as a signalling protocol. Since IMS i...

User position information is an important factor for achieving efficient operation of global wireless networks. It reduces the signalling load generated as a normal consequence of service provision. The basic constellation parameters that should be optimised in the design of the satellite segment of third generation wireless telecommunication networks (i.e., S-UMTS) to provide fast and accurate...

The Internet of Things (IoT) is a new concept for telecommunication development. The IoT and things determinations are considering in accordance the ITU-T recommendations. The Ubiquitous sensor Network (USN) is one of the general IoT components. The traffic models for such network should be studied well. The USN traffic models study results for image applications are considered in this paper. T...

Due to the increase in traffic volume and service diversity in telecommunication networks, efficient processing of calls and signalling functions in digital exchanges is becoming crucial to the operation of such networks. This paper describes a hierarchical model of the control system in an exchange. The model is represented as an M/G/1 queueing network and it is used for investigation of syste...

A new protocol which could be used for the transport of telecommunication signalling messages over an IPbased network is currently being discussed within the IETF. The protocol is called Stream Control Transmission Protocol (SCTP). In this paper we shortly describe SCTP and an implementation of SCTP. Furthermore, we evaluate how the protocol performs in an wide area network, especially when com...

background: echinococcus multilocularis is a tiny tapeworm, responsible for 0.3~0.5 million alveolar echinococcosis in humans. methods: we searched relevant papers published between 1981 and 2013 based on the database sources such as pubmed and google scholar, and collected and integrated the data for analysis. results: the parasite is able to use host-originated molecules to modulate its devel...

The beginning of the 1990s brought new technologies in the telecommunication networks. Asynchronous Transfer Mode (ATM) has been chosen as the transmission technology of broadband networks. The standardisation of ATM is practically finished today, the implementations are ready and the ATM equipment is largely introduced by users and service providers. At the end of the 1990s the Internet Protoc...
