Layered view of QoS issues in IP-based mobile wireless networks

The concept of 3G networks is based on an all-IP architecture supporting voice, video and data, and is driven by the needs for more bandwidth, more network capacity, and new radio spectrum. This gives rise to the need for performance enhancements and QoS guarantees in wireless networks. Internet Engineering Task Force (IETF) has defined QoS as a service agreement (or a guarantee) to provide a set of measurable networking service attributes, including end-to-end delay, delay variation (jitter), and available bandwidth.

Data Technologies in 3G Access Networks

Service providers are moving toward a model where anything that can be performed on a current IP network today, can be performed on a 3G wireless network. Mobile operators, specifically, are moving away from running packet-switched services over TDM networks, and running data over an efficient and cost effective data-focused infrastructure. This paper outlines the evolution of wireless technology, standards and networks with a focus on the data access network infrastructure as carriers migrate from 2G to 3G. It also details how Ciena's DN 7000 Series cost-effectively supports these access networks and helps facilitate the overall network migration from ATM to IP/MPLS.

High Speed Packet Access Solution

The volume of IP (Internet Protocol) traffic has already exceeded that for circuit-switched traffic in most fixed networks. The same change will happen in mobile networks as new IP-based mobile services, such as video news bulletins, downloading music or checking bus arrivals, become available and are used by more people in their daily communications.
