Preface
    Mobility is the key to the success of wireless networks. Roaming has extended the definition of mobility beyond the technology, network, and country boundaries. Is not it fascinating to make or receive calls anywhere in the world using the same phone and identity? International roaming is already proven to be one of the most popular features of today’s wireless network. With the advent and widespread deployment
of GSM technology, the mobile users have flexibility to use services in more than 500 networks. Inter-standard roaming has also made significant progress in recent years. Roaming capability in GPRS and 3G
networks is progressively being implemented. The convergence of wireless mobility with Wi-Fi/WiMax is on card. The day is not far when a mobile user will be able to seamlessly roam anywhere regardless of the
network, location, and device.
    Interworking technology and operation and the business processes that enable roaming are complex. The main purpose of this book is to provide readers a comprehensive overview of roaming implementation,
architecture, and protocols and its evolution from voice roaming in GSM to data roaming in GPRS and 3G networks. It can also be used as a guidebook to those who are responsible for roaming testing,  aintenance,
and management.
Chapter 1 introduces the key flavors of the roaming services to the readers.
Chapter 2 provides an  verview of Common Channel Signalling System number 7 (CCS7 or SS7).
The CCS7 is the basis for the inter network communication between two wireless networks and it plays a key role in enabling roaming between two partner networks. Understanding of CCS7 is must to grasp the concept of roaming.
Chapters 3, 4, and 5 provide an overview of GSM, GPRS and 3G networks, and the protocols. Understanding of radio and core network protocols is required to appreciate the inter network roaming transactions and call procedures.
Chapter 6 focuses on the inter PLMN network infrastructure requirements for roaming and procedures for voice roaming in GSM network.
Chapter 7 describes the additional requirements to enable data roaming in GPRS and 3G networks and the associated protocols.
Chapter 8 discusses the issues related to implementation of roaming for the prepaid
subscribers. It also describes the available alternatives to implement roaming
for the prepaid subscribers.
Chapter 9 focuses on the inter PLMN roaming tests, which are performed before launching roaming services in collaboration with a partner network.
Chapter 10 discusses the issues and challenges to manage roaming services. It also describes the best
practices to isolate and diagnose common roaming faults. The billing and settlement procedures for roaming services are quite different from the retail and wholesale billing for other services.
Chapter 11 discusses the billing process and the format specified for the usage of services in foreign networks. To enhance the customer experience while roaming, the wireless service providers are constantly introducing new value-added services.
Chapter 12 discusses few of the popular services and implementation. New radio access technologies such as WLAN and WiMAX offer new potential and opportunities.
Chapter 13 discusses WLAN and PLMN convergence and possible roaming scenarios.
