The service platform consists of: service network access products, IP infrastructure servers, service enablers consisting of service capability servers, application support servers, and other gateways. It also includes: service network management, which in turn consists of the personal service management, application servers and applications, hardware/service platforms for the servers. Thus, a launch service network will incorporate the VHE concept as a scenario where one can consistently access telecom and datacom services, through personalized user interface, from any network, on any terminal, anywhere. 9.8.2 The SIM Application Toolkit (SAT) The SAT browser on the (U) SIM card and the SIM Application Toolkit Service Capa- bility Server (SAT SCS) allow subscribers to access standard Web applications on the Internet, exploiting the widespread Web technology and the inherent security of smart cards, and opening up a whole new range of applications, such as wireless electronic commerce. A SAT Service Capability Server (SAT-SCS) solution affords service providers or net- work operators, as well as content providers to supply advanced services using standard tools and either HTML or the Wireless Mark-up Language (WML), where the Wireless Application Protocol (WAP) defines the latter. Thus, 3G terminals complying with the SIM application toolkit can co-exist with WAP terminals accessing the same services. The SAT SCS does not depend on the SIM card supplier. The UMTS Network and Radio Access Technology Coupling the SIM's inherent potential to solve security issues and Over-The-Air (OTA) provisioning for devi
