The Extensible Messaging and Presence Protocol (XMPP) is one of the most popular Instant Messaging (IM) protocols which uses a client-server working mode. This protocol uses different connection primitives for both client-to-server (c2s) and server-to-server (s2s) connections. It is actively used in mission-critical operations where the reliability and security of communication systems is always imperative...
User connectivity patterns in network applications are known to be heterogeneous and to follow periodic (daily and weekly) patterns. In many cases, the regularity and the correlation of those patterns is problematic: For network applications, many connected users create peaks of demand; in contrast, in peer-to-peer scenarios, having few users online results in a scarcity of available resources. On...
WebRTC, browser-to-browser communication technology, has on short term a desktop strategy, which will unleash its potential in 2013/2014. It is a great opportunity for Telco's to achieve a promise of service continuity for the RCS standard. But general disintermediation patterns and WebRTC going mobile and being an API of its own, are a serious mid-term challenge for operators.
In Recent years, the development of smart home applications based on OSGi framework has attracted increasing attention on the delivery of services on heterogeneous devices or platforms. In OSGi framework, bundles communicate with each other through service layer. However, the communication across OSGi frameworks for sharing services or exchanging information is rather limited and has no standard definition...
The paper investigates the capabilities for third party control on instant messaging functions in all IP-based managed networks. The open access to network functions is provided through Open Service Access (OSA) interfaces. A mapping of OSA User Interaction interfaces onto Session Initiation Protocol and Message Session Relay Protocol is proposed. A formal approach to functional verification of OSA...
The campus management service system uses the Visual C++6.0 to design graphical interface, and encapsulate the products to ensure the confidentiality of technology. As the time of student to school and leave school is more focused, the instant messaging of the SMS is very large, so to use a variety of technologies to enhance the generation, processing, sending and receiving speed of the SMS, this...
With mobile terminals and wireless network environment constantly being improved, people are using mobile instant messaging (IM) products more frequently. We provide a novel design based on Jabber and FCAPS model to meet the rapidly growing and changing needs. Jabber provides an open, secure, real-time communication technology. Network management has always been a key aspect of communication networks...
With the rapid advancement of wireless network technologies, Mobile Instant Messaging (IM) has become a major application in the telecommunications industry. Firstly, this paper introduces recent research and development efforts in constructing mobile IM systems. Secondly, it advances a new service model and implementation mechanism based on Jabber/XMPP. The communication protocol of our system provides...
