EVOLVING MOBILE NETWORKS While the history of mobile communications is long [1–3], and the background of mo bile networks therebyx is also long, in this chapter we focus on the historic evolution in terms of network architecture and services starting with 2nd generation (2G) mobile systems. In particular we consider the development of the architecture of Global Systems for Mobile Communications (GSM), since it is by far the most widespread mobile system in the world today.

SERVICE COMPONENTS IN UMTS BACKGROUND UMTS services will not only offer mobile services supported by 2nd generation systems such as GSM, but will also expand these services to higher rates and greater flexibility. The services evolving in the GSM platform through its Circuit Switched (CS) and Packet Switched (PS) services will continue in UMTS while new services are introduced.

RESOURCE AND NETWORK MANAGEMENT INTRODUCTION Operating a 3G network involves managing resources and Network Elements (NE). This chapter covers these two aspects to complete the deployment issues started in Chapter 7. Resources here refer primarily to the radio resources and NE refers to the 3G building blocks, i.e. elements in the CS, PS and radio access networks.
