ICSA allows easy access to all system parameters, logs, and alarms. Adding Subscribers to the Service ICSA gives the cellular operator a wide range of ways to add new subscribers to the service. Subscribers can call customer care that performs the registration online using the ICSA Web Administrator, or the subscribers can register themselves. This new mailbox is then ready for immediate use. A mobile Internet system should be fully integrated with existing billing systems, particularly when the nature of services being introduced is taken into account.
Differential billing is supported for enhanced service development.
The modular design of the ICSA server platform provides flexibility and scalability. Expansion of the platform has been carefully studied to accommodate vertical expansion on the same service node and horizontal expansion on multiple platforms for traffic-sharing and resilience. In many ways, ICSA brings more functionality to cellular subscribers than fixed networks. Mobile e-mail services also generate responsive voice traffic. In an increasingly competitive communications marketplace, the innovative and successful applications of ICSA enable network operators to attract subscribers that are requesting value-added services and are willing to pay for them.
