Virtual Roaming Systems for GSM, GPRS and UMTS Open Connectivity in Practice

Virtual Roaming Systems for GSM, GPRS and UMTS: Open Connectivity in Practice focuses on the implementation of virtual roaming systems. It discusses previous SMS Hubs architecture used for SMS interworking as well as voice and data, GPRS, and 3G virtual roaming. In addition, the author extends the discussion of virtual roaming to include location based services and optimal routing. This is one of the first books on the subject of virtual roaming, and provides a thorough and detailed technical explanation of the topic. It also covers side subjects such as 'Over the Air' (OTA) provisioning and geo-localisation in a virtual roaming environment. Lastly, the author explores the application of MAP, CAMEL, TCAP, SCCP, and GTP. Provides a thorough and detailed technical coverage of virtual and optimised roaming systems for mobile networks Explores the application of MAP, CAMEL, TCAP, SCCP, and GTP Discusses previous SMS Hubs architecture used for SMS interworking such as voice, data, and 3G virtual roaming Includes material on pre-paid case with CAMEL parameter transformations, the SMS, the Supplementary Services and USSD implementation Focuses on roaming hubs (including a brief introduction to Sigtran configuration)
