An Architecture for a Next Generation Voip Transmission Systems
An Architecture for a Next Generation VoIP Transmission Systems Christian Hoene1, Kai Clüver2, Jan Weil2 1Wilhelm-Schickard-Institute, University of Tübingen, Germany 2Fachgebiet Nachrichtenübertragung, Technical University of Berlin, Germany 1.1 Abstract Packetized speech transmission systems implemented with Voice over IP are gaining momentum against the traditional circuit switched systems despite the fact that packet switched VoIP is two to three times less efficient then its circuit switched counter part. At the time same time it is supporting just a rather bad “toll” quality. We believe that it is time to for a new architecture developed from the scratch. An architecture that includes an Internet enabled speech codec and its transport system. This architecture manages the perceptual service quality while using the available transmission resources to its best. The transmission of speech is managed and controlled in respect to its speech quality, month-to-ear delay, bit-rate, frame-rate, and loss robustness. Beside the architecture, we describe the requirements for the Internet speech codec and its transport protocol and present the description of an interface between speech codec and transport protocol. 2 Introduction Internet Telephony is a mature technology that has gained increasing popularity against the traditional PSTN systems. Voice over IP (VoIP) is replacing the PSTN service on broadband access networks such as cable modems and DSL, as it is more cost efficient to use IP broadband access also for Internet telephony. In addition, future wireless broadband access networks such as the 3GPP’s Long Term Evaluation (LTE) radio technology will support telephone services only via VoIP [1]. -

1 Smartphones and Symbian OS
1 Smartphones and Symbian OS Symbian OS is a full-featured, open, mobile operating system that powers many of today’s smartphones. As these smartphones become more pow- erful and popular, the demand for smartphone software has grown. Symbian smartphones are shipped with a variety of useful pre-loaded and targeted applications, which are selected by each phone’s manu- facturer. Today, the average Symbian smartphone ships with over 30 pieces of third-party software pre-installed. However, the exciting aspect of Symbian smartphones is that they are ‘open’, meaning that users can further customize their phone experience by downloading, installing, and uninstalling applications written by third-party developers (or by the users themselves). Users can download applications from a PC to the smartphone through a link such as USB, or Bluetooth technology, or over-the-air via the Internet. With the largest installed base of smartphones worldwide, Symbian OS offers a great opportunity for software developers to establish them- selves in the mobile market by creating novel and exciting software for the growing mass of smartphone users around the world. There is a growing list of Symbian applications available as freeware or as paid downloads on numerous Internet sites (http://www.handango.com and http://www.epocware.com are good examples). They range from pro- ductivity, entertainment, navigation, multimedia, and communications software to programs that can count fast food calories, improve your golfCOPYRIGHTED swing, keep diaries, and calculate MATERIAL foreign currency exchange. And business opportunities aside, sometimes it’s just plain fun writing your own code to run on your own smartphone. -
