Prepaid accounts are replenished during multimedia sessions using the prepaid
accounts without interruption of the multimedia sessions. A prepay server monitors
and adjusts prepaid account balances based on usage of communications resources
as reported by elements of the communications network (100). If a processor
determines that an account balance is low, then a user terminal (102) is
notified and a new session is intiated to permit the user to increase the account
balance without interrupting the ongoing communications session.
