Sip Message Compression Technique For Efficient Multimedia Services In 3g Wireless Communications, Valerie Kenneally Jan 2003

Sip Message Compression Technique For Efficient Multimedia Services In 3g Wireless Communications, Valerie Kenneally

Theses

The direction of the global cellular industry is primarily determined by two standardisation bodies, the 3rd Generation Partnership Project (3GPP) (in Europe and Asia) and 3GPP2 (in North America). Both of these standardisation bodies are currently specifying a core network to deliver IP based multimedia services over 3G wireless networks. One of the fundamental building blocks of this IP based multimedia core network is the use of SIP (Session Initiation Protocol) as the control protocol. The radio resource, that is the available frequency spectrum, in wireless communication systems remains a limiting factor in terms of the bandwidth available to an …


Interactive Multimedia In The Teaching Of The Irish Language In Primary School : Design, Implementation And Development., Máire Lynch Jan 2003

Interactive Multimedia In The Teaching Of The Irish Language In Primary School : Design, Implementation And Development., Máire Lynch

Theses

This thesis focuses on interactive multimedia use specifically in the area of vocabulary acquisition in a second language. It addresses the language learning requirements of third class (nine year olds) language learners, in Primary school. The study is based on existing second language acquisition research, computer - assisted language learning and the design and development of educational multimedia and it delivers an interactive application based on them. The study is firmly rooted in the foundations of the Revised Curriculum for Irish Primary Schools most especially in the language teaching methods it recommends and its emphasis on the use of information …


Measuring Software Size For Continuous Process Improvement, Claire O'Sullivan Jan 2003

Measuring Software Size For Continuous Process Improvement, Claire O'Sullivan

Theses

This thesis looks at how the size of a software product can be measured. It looks at current software sizing methods (LOC and FPA) and shows that they are not sufficient in today’s rapidly changing environment. The COSMIC-FFP method is introduced and an overview of how it works is given. The hypothesis to be tested in this thesis is whether COSMIC-FFP is an accurate, repeatable sizing method that when applied to any type of software project produces a size measure that can be used to predict the effort required to complete the project.

This thesis investigates the use of the …


Heterogenous Network Management, Kenneth Carey Jan 2003

Heterogenous Network Management, Kenneth Carey

Theses

Enterprise level system development, integrating a broad range of arctures and legacy systems, has received significant attention over the last few yentegrated chain management, which allows companies to see their full manufactu inventory and sales channels, has driven much of this work. Delivering quality IP 1 wireless access is forcing similar integration in 2.5G and 3G telecom archires. Such integration has resulted in the emergence of multi-protocol heterogeneietworks, combining IP core backbones, legacy databases and switchinghnology. Heterogeneous networks, due to their diversity of equipment and suppoDrotocols, introduce challenges for today's network administrators, particularly ii areas of device configuration and alarm …
