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 …

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 …
