Introduction to Mobile Telephony

2002
What follows is concerned with the evolution of, and prospects for, so-called third-generation or 3G services provided using mobile devices. It is particularly concerned with developments in Western Europe because that is where most progress has so far been made in terms of the number of countries involved, but full account is also taken of ...

Improving mobile video telephony

2014 Eleventh Annual IEEE International Conference on Sensing, Communication, and Networking (SECON), 2014
Video telephony is becoming popular over smart-phones and tablets. Unlike the Desktop era, smartphone users are often ‘mobile’ and this impacts how the video is processed and transmitted over the network. The significant increase in the motion content in such videos change the composition of video frames.

Mobile IP telephony: mobility support of SIP

Proceedings Eight International Conference on Computer Communications and Networks (Cat. No.99EX370), 2003
The Internet has recently become the most important, most popular way of communication. A significant new feature of the Internet is the support of telephony. Two main competing signaling protocol standards have been developed for this purpose: H.323, proposed by the ITU, and SIP, proposed by the IETF.

Off the hook [Mobile telephony]

Engineering & Technology, 2007
Things are about to change for mobile network operators, although they don't yet know whether it will be for better or worse. What the operators do know is that, unless they find a way to adjust their business models, they risk becoming nothing more than providers of low-cost mobile data connections that carry other people's money- making services ...

Mobile telephony in the next decade

37th IEEE Vehicular Technology Conference, 1987
The main purpose of this paper is to analyse the technical future of cellular radio. It is shown that the best technical solution for the end of the century is a new concept based on digital TDMA technology. It is also concluded that the growth potential for current analog systems is enough to take care of the demand up to a time when the new ...

Context Information in Mobile Telephony

2003
Most research in context-aware computing offers definitions of context that consist solely of measurable information. Using mobile telephony as an example of a computing area, we provide a set of context information relevant to the area drawn from a qualitative case study: identity, location, time and present activity.

The Case of Cellular Mobile Telephony [PDF]

, 2001
Since their invention in the 1920s, mobile telephone services have evolved only gradually over time as a niche market unnoticed by most businesses and consumers. Yet, mobile telephony has revolutionised telecommunications in the 1990s. The international diffusion of mobile telephony took off in the 1990s when new digital technology was introduced and ...

Mobile IPv6 and cellular telephony

WCC 2000 - ICCT 2000. 2000 International Conference on Communication Technology Proceedings (Cat. No.00EX420), 2002
We emphasize the need for IPv6 addressability for handling the billion-plus wireless IP devices that are expected to be sold within the next three years. Since these devices are wireless and therefore mobile, they will derive great benefit from Mobile IPv6.

m-security (security and mobile telephony)

Proceedings IEEE 35th Annual 2001 International Carnahan Conference on Security Technology (Cat. No.01CH37186), 2002
This paper shows a view of the relationship, now closer than ever, between mobile telephony and security. The paper focuses on this relationship as it stands at the moment with regard to its functional nature and the technology involved, and how the relationship will vary in the very near future, when forthcoming technologies will improve and refine ...
