Broadcast replenishment of account parameters for groups of wireless devices
View Patent ↗A system and method are provided for the broadcast replenishment of account parameters for select groups of wireless devices, where select groups of wireless devices have their internally-stored account parameters (e.g., prepaid amount of usage authorization) simultaneously updated as a group by a single broadcast message, such as an encrypted SMS message. An account update message is generated based on the account parameters to be updated and encrypted using an encryption key uniquely associated with the select group of wireless devices. The encrypted account update message is broadcast for receipt by the select group of wireless devices, such only those wireless devices previously provided with a key for decryption can receive and decrypt the broadcast account update message. The wireless devices use information and/or instructions in the broadcast message in order to update their internally stored account parameters accordingly.

5. The method of claim 1 , further comprising broadcasting the Short Message Service (SMS) message over a predetermined SMS cell broadcast channel subscribed to by the group the wireless devices.
6. The method of claim 1 , further comprising providing the group of wireless devices with a decryption key capable of decrypting the broadcast encrypted account update message.
7. The method of claim 1 , further comprising including an identification within the encrypted account update message such that each broadcast encrypted account update message is capable of being separately identified and acted upon by the wireless devices.
8. A system for replenishing internally stored account parameters on a select group of wireless devices, comprising:
means for determining a need for a required change in at least one internally stored account parameter associated with a prepaid amount of authorization for wireless usage of the wireless device in the select group of wireless devices;
means for obtaining an encryption key uniquely associated with the group of wireless devices;
means for generating an encrypted account update message using the encryption key and the selected at least one account parameter to be changed that includes the amount of authorization for wireless usage of the wireless device; and
means for broadcasting the encrypted account update message for receipt by the group of wireless devices in order to update the internally stored account parameters within the group of wireless devices to replenish their internally stored prepaid amount of authorization for wireless usage of the wireless device, wherein the broadcast encrypted account update message is only able to be received and decrypted by those wireless devices within the group of wireless devices.
9. The system of claim 8 , further comprising means for automatically replenishing the internally stored prepaid amount of authorization for usage of the wireless devices on a periodic basis based on internally stored rules regardless of whether the broadcast encrypted account update message is received by any of the wireless devices.
10. The system of claim 8 , wherein the broadcast encrypted account update message provides the same prepaid amount of authorization for usage of the wireless device to be replenished on each wireless device in the group of wireless devices.
11. The system of claim 8 , wherein the encrypted account update message is a Short Message Service (SMS) message.
12. The system of claim 8 , wherein the means for broadcasting is further configured for broadcasting the Short Message Service (SMS) message over a predetermined SMS cell broadcast channel subscribed to by the group the wireless devices.
13. The system of claim 8 , further comprising means for providing the group of wireless devices with a decryption key capable of decrypting the broadcast encrypted account update message.
14. The system of claim 8 , wherein the means for generating an encrypted account update message is further configured for including an identification within the encrypted account update message such that each broadcast encrypted account update message is capable of being separately identified and acted upon by the wireless devices.
15. A system for replenishing internally stored account parameters on a select group of wireless devices, comprising:
a database containing an encryption key uniquely associated with the group of wireless devices;
a provisioning server comprising a processor and a readable storage media coupled to the processor for tangibly storing thereon instructions executable by the processor to perform operations comprising:
determining a need for a required change in at least one internally stored account parameter associated with a prepaid amount of authorization for wireless usage of the wireless device in the select group of wireless devices;
obtaining the encryption key from the database associated with the group of wireless devices;
generating an encrypted account update message using the encryption key and the selected at least one account parameter to be changed that includes the amount of authorization for wireless usage of the wireless device; and
broadcasting the encrypted account update message for receipt by the group of wireless devices in order to update the internally stored account parameters within the group of wireless devices to replenish their internally stored prepaid amount of wireless authorization for usage of the wireless device, wherein the broadcast encrypted account update message is only able to be received and decrypted by those wireless devices within the group of wireless devices.
16. The system of claim 15 , further comprising means for automatically replenishing the internally stored prepaid amount of authorization for usage of the wireless devices on a periodic basis based on internally stored rules regardless of whether the broadcast encrypted account update message is received by any of the wireless devices.
17. The system of claim 15 , wherein the broadcast encrypted account update message provides the same prepaid amount of authorization for usage of the wireless device to be replenished on each wireless device in the group of wireless devices.
18. The system of claim 15 , wherein the encrypted account update message is a Short Message Service (SMS) message.
19. The system of claim 15 , further comprising stored instructions executable by the server processor for broadcasting the Short Message Service (SMS) message over a predetermined SMS cell broadcast channel subscribed to by the group the wireless devices.
20. The system of claim 15 , further comprising stored instructions executable by the server processor for including an identification within the encrypted account update message such that each broadcast encrypted account update message is capable of being separately identified and acted upon by the wireless devices.
21. A method for updating internally stored account parameters on a select group of wireless devices, the method comprising:
