STOCKHOLM, Sweden-L.M. Ericsson said it launched a network function called PrePaid Calling Service for wireless networks that use Advanced Mobile Phone Service and digital-AMPS standards.
Ericsson’s new service allows for prepayment of value-added features like fax, voice mail and short message service, whereas operators previously could not account and charge for those services on a prepaid basis.
By paying in advance for mobile phone services, users build up airtime credits that are automatically deducted in real time, every time the phone is used and they are told how much credit remains at the start of each call. Subscribers can continue to use up their prepaid airtime even when they are roaming into other networks.
Prepaid subscription also offers benefits to operators, like improved cash flow and reduced exposure to fraud. Wireless operators can reach new market segments, including communities that don’t have access to financial credit and individual users who don’t have good credit.
