Abstract
A system and method of providing a prepaid subscriber service to a mobile subscriber in an integrated wireless telecommunications network having a circuit-switched portion and a General Packet Radio Service (GPRS) packet-switched portion. A prepaid subscriber class (PPSC) is stored in a home location register (HLR), and the PPSC is sent from the HLR to a serving mobile switching center (MSC) when the subscriber registers in the circuit-switched portion of the network. The PPSC is sent from the HLR to a serving GPRS support node (SGSN) when the subscriber registers in the packet-switched portion of the network. Also, the PPSC may be sent from the SGSN to a Gateway GPRS Support Node (GGSN) in order to indicate that the subscriber is a prepaid subscriber. When the mobile subscriber begins a packet-switched data session, the SGSN, GGSN, or both periodically send partial call data records (CDRs) to a prepaid center (PPC). When the mobile subscriber begins a circuit-switched call, the MSC periodically sends partial CDRs to the PPC. The PPC calculates in near real time, a new account balance for the prepaid subscriber. The current call is disconnected, and prepaid services are stopped when the account balance is reduced to zero.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
