Abstract

This disclosure generally relates to mobile subscriber identities for mobile devices, and more particularly, to dynamic assignment of International Mobile Subscriber Identities (IMSIs) to reduce roaming and overuse charges. Instead of using a reprogrammable embedded Subscriber Identity Module (SIM) card for remote activation of a device, mobile carrier charges, such as roaming and over limit usage fees, can be significantly reduced by reprogramming SIM cards dynamically from a pool of available mobile accounts. A smaller pool can be utilized to meet the needs of a large group, rather than a one-to-one association implemented within today's phones. Resource usage can be tracked and as one account reaches its maximum, a new account can be assigned to the mobile device to prevent overuse charges. Existing FMC concepts can insure single number inbound or outbound caller identification regardless of the name or number associated with the SIM card for the mobile device.

Claims (38)

1. A method of dynamically assigning a mobile subscriber identity to a device comprising:

receiving a user identification and a request for a mobile subscriber identity from a device;

authenticating said user identification received from said device;

assigning a mobile subscriber identity to said device in response to said request;

associating said mobile subscriber identity with said user identification; and providing said mobile subscriber identity to said device, wherein assigning said mobile subscriber identity to said device comprises comparing the level of usage of said device with subscriber information, and selecting a mobile subscriber identity in dependence upon the result of the comparison.

2. The method of claim 1 , wherein authenticating said user identification comprises determining whether a user associated with said user identification has access to a pool of mobile subscriber identities.

3. The method of claim 1 , wherein the level of usage represents the available minutes or data of said device.

4. The method of claim 1 , comprising:

disassociating said mobile subscriber identity with said user identification when said mobile subscriber identity provided to said device reaches a defined threshold;

assigning a new mobile subscriber identity to said device;

associating said new mobile subscriber identity with said user identification; and

providing said new mobile subscriber identity to said device

5. The method of claim 4 , comprising returning said mobile subscriber identity to a pool of mobile subscriber identities.

6. The method of claim 1 , comprising receiving monitoring messages from said device and keeping said mobile subscriber identity active.

7. The method of claim 6 , comprising disassociating said mobile subscriber identity with said user identification when failing to receive said monitoring messages and returning said mobile subscriber identity to a pool of mobile subscriber identities.

8. The method of claim 1 , comprising receiving a current location of said device and wherein assigning said mobile subscriber identity to said device comprises selecting said mobile subscriber identity based on said current location of said device.

9. A system comprising:

a server managing a pool of unique identifications;

wherein said server receives a request for a unique identification from said pool of unique identifications by a mobile device, determines an availability of a unique identification and provides said unique identification and a private encryption key to said mobile device when said unique identification is available, said unique identification and private encryption key programmed into a subscriber identity module card of said mobile device for establishing communications,

wherein determination of the availability of a unique identification comprises the server comparing the level of usage of the mobile device with subscriber information, and selecting a mobile subscriber identity in dependence upon the result of the comparison.

10. The system of claim 9 , wherein determining the level of usage represents the useable minutes or data of the device.

11. The system of claim 9 , comprising a plurality of pools for maintaining unique identifications.

12. The system of claim 9 , wherein said unique identification is returned to said pool when said unique identification is inactive on said mobile device.

13. The system of claim 9 , wherein a new unique identification is assigned to said mobile device when said unique identification reaches a threshold of minutes or data usage.

14. The system of claim 9 , wherein said pool of unique identifications is updated periodically based on usage.

15. A mobile device comprising:

a subscriber identity module card;

at least one processor; and

a memory operatively coupled to said processor, said memory storing program instructions that when executed by said processor, causes said processor to:

provide subscriber information;

request for a mobile subscriber identity;

receive a mobile subscriber identity and an encryption key in accordance with a comparison between the level of usage of the device and the provided subscriber information;

program said subscriber identity module card with said mobile subscriber identity and encryption key; and establish communications through said subscriber identity module card.

16. The mobile device of claim 15 , wherein requesting for said mobile subscriber identity comprises detecting a presence of a WiFi™ network and sending a request to a pool manager having a plurality of mobile subscriber identities through said WiFi™ network.

17. The mobile device of claim 15 , wherein requesting for said mobile subscriber identity comprises sending a registration mobile subscriber identity to a pool manager having a plurality of mobile subscriber identities through a carrier network.

18. The mobile device of claim 17 , wherein said registration mobile subscriber identity is embedded into said mobile device or synchronized within said mobile device when a WiFi™ network is available.

19. The mobile device of claim 17 , wherein said registration mobile subscriber identity is shared among a plurality of devices.

20. The mobile device of claim 15 , wherein requesting for said mobile subscriber identity comprises sending a personal mobile subscriber identity to a pool manager having a plurality of mobile subscriber identities and replacing said personal mobile subscriber identity with said mobile subscriber identity.
