Abstract

Systems and methods wherein the wireless device operates as a service control point (“SCP”) in a wireless service network. The billing system controls the service control point in the wireless device by periodically supplying increments of value from a master account balance. The billing system may also periodically update the service rules and authorizations maintained within the wireless device. Usage information such as call details records may also periodically be uploaded from the wireless device to the billing system. The service control function software in the wireless device and the billing system communicate with each other via administrative messages using over the air data bearer services of the network. The amount and frequency of the additional service authorizations and other communications vary, potentially on a service by service basis, depending upon the credit risks, fraud risks, user preferences, rate plans, available network resources, and other parameters.

Claims

1. A system for managing local control of access to a wireless network, the system comprising:

a wireless device with a processor, memory, and first software code; and

wherein the first software code is configured to receive messages via the wireless network, wherein each message or a set of messages represents an amount of authorized use;

wherein the first software code is configured to modify a locally stored account by each amount of authorized use received, determine a charge for each use of the wireless device, and modify the locally stored account in real time for each charge determined;

wherein the second software code is configured to send the messages via the wireless network representing the amounts of authorized use, and modify a centrally stored account for each amount of authorized use sent;

wherein the frequency of sending amounts of authorized use to the wireless device is based upon at least one of a group comprising credit risk, fraud risk, user preferences, rate plans, and available network resources; and

wherein the first software code restricts access to the wireless network, or restricts use of the wireless device, when the balance in the locally stored account is at or below a predetermined amount and there are no additional amounts of authorized use available from the second software code.

2. The system of claim 1 wherein the second software code is configured to modify the centrally stored account by an amount representing a payment received or a modification in available credit.

3. The system of claim 1 wherein rules and/or data used by the first software code to determine charges for use of the wireless device are different from the rules and/or data used by the second software code to determine charges for use of the wireless device.

4. The system of claim 3 wherein the second software code is configured to send a message, or set of messages, to the first software code to modify the locally stored account balance when the second software code modifies the centrally stored account based on rules and/or data that differ from those used by the first software code.

5. The system of claim 1 wherein the second software code is configured to receive data records from the wireless network with information regarding use of the wireless device, determine charges for use of the wireless device based on the data records, and modify the centrally stored account for each charge determined.

6. The system of claim 5 wherein the second software code is configured to compare the centrally stored account with the locally stored account and, if different, send a message, or set of messages, to the first software code to modify the locally stored account balance to be equal to the centrally stored account balance.

7. The system of claim 1 wherein the first software code is configured to create data records with information regarding use of the wireless device and communicate the data records to the second software code in messages sent via the wireless network.

8. The system of claim 7 wherein the messages sent by the first software code to the second software code are SMS messages.

9. The system of claim 1 wherein the messages sent by the second software code to the first software code are SMS messages.

10. The system of claim 1 wherein the messages sent by the second software code to the first software code are signaling messages.

11. The system of claim 1 wherein the messages sent by the second software code to the first software code are encrypted.

12. The system of claim 1 wherein the messages sent by the second software code to the first software code include at least one of a group comprising changes to the rates used by the first software code to determine a charge for use of the wireless device, changes to barred telephone numbers, changes to barred websites, changes to allowed telephone numbers, changes to allowed websites, and promotional messages.

13. The system of claim 1 wherein the first software code is configured to prevent the wireless device from making any calls except calls to emergency services and calls to a customer service center when the balance in the locally stored account is at or below a predetermined amount and there are no additional amounts of authorized use available from the second software code.

14. The system of claim 13 wherein the first software code is configured to prevent the wireless device from receiving any calls when the balance in the locally stored account is at or below a predetermined amount and there are no additional amounts of authorized use available from the second software code.

15. A method for managing local control of access to a wireless network, the method comprising:

providing a wireless device that includes a processor, memory, and first software code;

providing a central billing system that includes a processor, memory and second software code;

sending messages via the wireless network from the central billing system to the wireless device, wherein the first software code is configured to receive messages via the wireless network, wherein each message or a set of messages represents an amount of authorized use, and wherein the second software code is configured to send the messages via the wireless network representing the amounts of authorized use;

modifying, with the first software code, a locally stored account by each amount of authorized use received;

determining, with the first software code, a charge for each use of the wireless device;

modifying, with the first software code, the locally stored account in real time for each charge determined; and

modifying, with the second software code, a centrally stored account for each amount of authorized use sent;

wherein the frequency of sending amounts of authorized use to the wireless device is based upon at least one of a group comprising credit risk, fraud risk, user preferences, rate plans, and available network resources; and

wherein the first software code restricts further access to the wireless network, or restricts use of the wireless device, when the balance in the locally stored account is at or below a predetermined amount and there are no additional amounts of authorized use available from the second software code.

16. The method of claim 15 wherein the second software code modifies the centrally stored account by an amount representing a payment received or a modification in available credit.

17. The method of claim 15 wherein rules and/or data are used by the first software code to determine charges for use of the wireless device that are different from rules and/or data used by the second software code to determine charges for use of the wireless device.

18. The method of claim 17 further comprising the second software code sending a message, or set of messages, to the first software code to modify the locally stored account balance when the second software code modifies the centrally stored account based on rules and/or data that differ from those used by the first software code.

19.
