The method of communicating a currency credit balance to a telecommunications device (10) comprises the steps of registering the device with a node, such as a Mobile Service Center (20), querying a PrePaid Complex (50) by the node, a response (120) thereto to determine the prepaid currency credit balance, responding to the query with the actual prepaid currency credit balance in monetary units, and sending the balance information to the device (10). The method can not only be implemented upon registration of the device, but also during an ongoing call connection according to a preselected time interval, or at the termination of an ongoing call connection. The invention also includes a node (250) which enables communicating the prepaid currency credit balance to the telecommunications device (10), wherein the node includes a program module (260) adapted to query the prepaid complex (50) to determine the balance, receive a response from the complex which includes the balance, and send the balance to the device (10). The query, response, and sending of balance information can occur at the time the device (10) is registered, during an ongoing call connection according to a preselected time interval, or at the termination of an ongoing call connection. |
