Abstract

A system, method, and computer readable medium comprising instructions for handling insufficient account balance of subscribers in a mobile communications network is disclosed. A request for communication is received from a mobile station. A determination is made as to whether a subscriber of the mobile station has an insufficient account balance. If the subscriber has an insufficient account balance, the request is withheld and the mobile station is notified by a short message.

Claims

1. A method, comprising:

receiving a request for communication from a mobile station;

determining if a subscriber of a destination mobile station has an insufficient account balance;

withholding the request for communication;

notifying the destination mobile station if the subscriber has an insufficient account balance; and

notifying the mobile station of the insufficient account balance, regardless of whether a voice call or a short messaging service via the mobile station is in progress, wherein the notification comprises instructions regarding how to recover the withheld request for communication.

2. The method of claim 1, comprising determining if a subscriber of the mobile station has an insufficient account balance, wherein the determining comprises:

sending a query for an account balance of the subscriber to a server;

receiving the account balance from the server; and

determining if the account balance is below a predetermined threshold amount.

3. The method of claim 2, wherein the query is sent to the server periodically.

4. The method of claim 2, comprising notifying the mobile station automatically if the account balance is above the predetermined threshold amount.

5. The method of claim 4, wherein the notifying comprises sending a short message indicating an insufficient account balance to the mobile station and wherein the short message comprises time and date of the request.

6. The method of claim 5, wherein the short message is sent to the mobile station periodically.

7. The method of claim 3, wherein the short message comprises instructions on how to replenish funds.

8. The method of claim 1, further comprising forwarding the request to the destination mobile station if the subscriber has a sufficient account balance.

9. A non-transitory computer readable medium comprising instructions that when read by a processor cause the processor to perform:

receiving a request for communication from a mobile station;

determining if a subscriber of a destination mobile station has an insufficient account balance;

withholding the request for communication;

notifying the destination mobile station if the subscriber has an insufficient account balance; and

notifying the mobile station of the insufficient account balance, regardless of whether a voice call or a short messaging service via the mobile station is in progress, wherein the notification comprises instructions regarding how to recover the withheld request for communication.

10. The non-transitory computer readable medium of claim 9, comprising determining if a subscriber of the mobile station has an insufficient account balance, wherein the determining comprises:

sending a query for an account balance of the subscriber to a server;

receiving the account balance from the server; and

determining if the account balance is below a predetermined threshold amount.

11. The non-transitory computer readable medium of claim 10, wherein the query is sent to the server periodically.

12. The non-transitory computer readable medium of claim 10, comprising notifying the mobile station automatically if the account balance is above the predetermined threshold amount.

13. The non-transitory computer readable medium of claim 12, wherein the notifying comprises sending a short message indicating an insufficient account balance to the mobile station and wherein the short message comprises time and date of the request.

14. The non-transitory computer readable medium of claim 13, wherein the short message is sent to the mobile station periodically.

15. The non-transitory computer readable medium of claim 11, wherein the short message comprises instructions on how to replenish funds.

16. The non-transitory computer readable medium of claim 9, further comprising forwarding the request to the destination mobile station if the subscriber has a sufficient account balance.

17. A system, comprising:

at least one mobile station;

at least one mobile switching center communicably connected to the at least one mobile station and at least one short message service center;

at least one short message service center communicably connected to at least one mobile switching center; and

a server communicably connected to the at least one short message service center,

wherein the at least one short message service center;

receives a request for communication from a mobile station;

determines if a subscriber of a destination mobile station has an insufficient account balance;

withholds the request for communication;

notifies the destination mobile station if the subscriber has an insufficient account balance; and

notifies the mobile station of the insufficient account balance, regardless of whether a voice call or a short messaging service via the mobile station is in progress, wherein the notification comprises instructions regarding how to recover the withheld request for communication.
