A Prepaid Data Hub for maintaining pre-payment information for roaming subscribers. The Hub interacts with two or more wireless telecommunication systems that implement two different wireless protocols and which may be operated by different wireless service providers. The Hub retrieves pre-payment information using two or more different protocols, with a first protocol being native to the home network, but a second protocol being an external prepaid portal protocol. The Hub also monitors subscriber data traffic to limit the amount of access consumed in a subscriber session, notify subscribers of a low balance, and the like. The Hub eliminates the need for network gateway devices to themselves provide control over and/or maintain pre-payment information. |
