Case Study IP RAN and Mobile Backhaul QOS

This chapter presents a quality of service (QoS) case study for IP‐based radio access networks (RANs) as part of a mobile backhaul network. It discusses the components of second‐generation (2G) and third‐generation (3G) networks, and how traffic is carried on these networks. The chapter provides a brief introduction of 3G network evolution to fourth‐generation (4G) and long‐term evolution (LTE) that is necessary to describe the fundamental changes that occur with LTE and the packet transport for this service. It also discusses some basic mobile functions and features before explaining the QOS scenario for IP RAN and mobile backhaul. This discussion touches on the packet‐handling services in 3G and 4G networks. Global system for mobile communications (GSM), code division multiple access (CDMA), and any other pure mobile voice and signaling architectures are described briefly. Also, the 3rd generation partnership project (3GPP) evolution is covered only in generic terms.
