Broadcasting Mobile Multimedia Using WiMAX-Network Architectures
Published in Amitabh Kumar, Mobile Broadcasting with WiMAX: Principles, Technology, and Applications, 2014
The origin of IMS lay in the need for integrating the general packet radio services (GPRS) networks, which were packet-based to the internet, and in general provide support for voice and multimedia services in the cellular domain. The IMS was unveiled in Release 5 of the 3GPP with Release 6 adding support for wireless networks and Release 7 for fixed networks. The interface functions of IMS include signaling and media format conversions, among others. The IMS is today characterized by a range of services which are fully defined at the application level. The examples of such services are push-to-talk over cellular, instant messaging and VoIP; additional services such as video calls, streaming, etc., can be defined at the application level. IMS makes the applications operate across multiple networks seamlessly, irrespective of the media formats and signaling systems or addressing architectures which are used on these networks by performing appropriate conversions.
10 Videoconferencing Over Ip
Published in Wes Simpson, Video Over IP, 2013
Work is under way to extend SIP to offer two features not found in basic H.323: support for instant messaging and presence. Instant messaging (IM) supports real-time, text-based communication between two or more users and has become very popular for both desktop and mobile users. Presence involves informing users about the current status of other users in whom they are interested. One popular use of presence is the buddy list feature of some IM systems that lets users know whether other people with whom they want to communicate are online or off-line. This concept is being extended to let users know if, for example, one of their buddies is available for a full videoconference or just for text-based messaging. SIMPLE, the SIP Instant Messaging Presence Leveraging Extensions working group of the IETF, is responsible for this work.
Writing as a Fundamental Mode of Communication
Published in Anne-Laure Fayard, Anca Metiu, The Power of Writing in Organizations, 2012
Drawing on communication and literacy theories (Bolter, 2001; Goody, 1987; Havelock, 1963; Ong, 1982/2002) as well as research in cognitive psychology (Wolf, 2008), we suggest that it is productive to think about current communicative practices by accounting for their essential nature as written communication and to analyze them not only in terms of technology (e.g., quill pen, pencil, typewriter), media (e.g., telephone, e-mail, slide presentations, instant messaging), and devices (e.g., laptop, desktop, smart phone) but also in terms of modes of communication, whether oral or written. Even the latest communication media rely on these two fundamental modes of communication. In fact, new technologies tend to include a mix of audio, text, and writing-based forms of communication, sometimes including video. Skype, for example, offers voice calls on the Internet but also video, as well as instant messaging. Increasingly, people use their mobile phones not only to make calls but also to send text messages and even check their e-mail. While each mode of communication can be performed with various media—each of which possesses its own affordances and uses—distinguishing between modes of communication and media is productive because it offers a framework for analyzing today’s communication practices, with their mix of oral and written components and with their ever-evolving features and capabilities.
Communicability of traditional interfaces VS chatbots in healthcare and smart home domains

As previously mentioned, the second reason that ensured the success of chatbot is the development of technology and the spread of smartphones. Smartphones are today used for several needs and consulted many times during the day. The instant messaging mechanism is familiar to most of those who own smartphones, thanks to the huge success of apps, such as Whatsapp, Telegram and Facebook Messenger. Through the chatbot interface, companies can create easy and pleasant conversations, leading to a more positive and engaging UX (Nocera et al. 2015; Brandtzaeg and Følstad 2017). Compared to traditional channels of communication, such as telephone calls and emails, chatbots are faster and always available, ensuring quick and easy answers related to different problems. Given the possibility to manage unlimited data and users, chatbots can also replace assistance service operators, who are not always available. As a recent report by My Clever Agency demonstrates (M. C. Agency, Chatbots: a consumer research study, 2016), chatbot is preferred by 84.6% of interviewed people as consumer channel to get answers, second only to face-to-face interactions, but still preferred to email or online form, chat with operators, phone, and social media.
