Abstract

A method includes receiving communication data that is directed to a first Mobile Directory Number (MDN) that is associated with a mobile communication device of a mobile subscriber. The first MDN is a local telephone number in a first country. The method includes determining a location of the mobile communication device. A first International Mobile Subscriber Identity (IMSI) number is active when the mobile communication device is located in the first country, and a second IMSI number is active when the mobile communication device is located in a second country. The method includes routing the communication data to the mobile communication device based on the location of the mobile communication device.

Claims

1. A non-transitory computer readable storage medium, comprising:

a multiple International Mobile Subscriber Identity (IMSI) location register (MILR) module to store;

a first IMSI number and a first Mobile Directory Number (MDN) associated with a mobile communication device of a mobile subscriber, wherein the first IMSI number and the first MDN are associated with a first country, and wherein the first MDN is a local telephone number in the first country;

a second IMSI number and a second MDN associated with the mobile communication device, wherein the second IMSI number and the second MDN number are associated with a second country, and wherein the second MDN is a local telephone number in the second country; and

location information, wherein the first IMSI number is active when the mobile communication device is located in the first country, and wherein the second IMSI number is active when the mobile communication device is located in the second country.

2. The non-transitory computer readable storage medium of claim 1, further comprising instructions that, when executed by a processor, cause the processor to:

determine, based on the location information, a location of the mobile communication device; and

route communication data to the mobile communication device based on the location of the mobile communication device.

3. The non-transitory computer readable storage medium of claim 2, further comprising instructions that, when executed by the processor, cause the processor to route the communication data to the mobile communication device via an Internet Protocol (IP) network when the mobile communication device is located in the second country.

4. The non-transitory computer readable storage medium of claim 2, further comprising instructions that, when executed by the processor, cause the processor to route the communication data to the mobile communication device when the mobile communication device is located in the first country.

5. The non-transitory computer readable storage medium of claim 1, wherein the MILR module further stores:

a third IMSI number and a third MDN associated with the mobile communication device, wherein the third IMSI number and the third MDN are associated with a third country, and wherein the third MDN is a local telephone number in the third country,

wherein the third IMSI number is active when the mobile communication device is located in the third country.

6. The non-transitory computer readable storage medium of claim 5, further comprising instructions that, when executed by the processor, cause the processor to:

determine, based on the location information, a location of the mobile communication device; and

route communication data to the mobile communication device via an Internet Protocol (IP) network when the mobile communication device is located in the third country.

7. A system comprising:

a distributed mobile architecture (DMA) server that is located in a first country, the DMA server comprising;

a processor;

a multiple International Mobile Subscriber Identity (IMSI) location register (MILR) module to store;

a first International Mobile Subscriber Identity (IMSI) number and a first Mobile Directory Number (MDN) associated with a mobile communication device of a mobile subscriber, wherein the first IMSI number and the first MDN are associated with a first country, and wherein the first MDN is a local telephone number in the first country;

a second IMSI number and a second MDN associated with the mobile communication device, wherein the second IMSI number and the second MDN number are associated with a second country, and wherein the second MDN is a local telephone number in the second country; and

location information, wherein the first IMSI number is active when the mobile communication device is located in the first country, and wherein the second IMSI number is active when the mobile communication device is located in the second country; and

instructions that, when executed by the processor, cause the processor to;

determine, based on the location information, a location of the mobile communication device; and

route communication data to the mobile communication device based on the location of the mobile communication device.

8. The system of claim 7, wherein the communication data is routed to the mobile communication device via an Internet Protocol (IP) network when the mobile communication device is located in the second country.

9. The system of claim 8, wherein the communication data is routed to a second DMA server that is located in the second country.

10. The system of claim 8, wherein no international or long distance charges are associated with routing the communication data to the second country via the IP network.

11. The system of claim 8, wherein the communication data is associated with a telephone call to the first MDN of the mobile subscriber.

12. The system of claim 8, wherein the communication data is associated with a short message service (SMS) message to the first MDN of the mobile subscriber.

13. The system of claim 8, wherein the IP network includes a wireless link between the first country and the second country.

14. The system of claim 8, wherein the wireless link includes a satellite link.

15. The system of claim 8, wherein the IP network includes a wired link between the first country and the second country.

16. The system of claim 8, wherein the first DMA server further comprises a base transceiver station (BTS) interface and wherein the communication data is routed to the mobile communication device via the BTS interface when the mobile communication device is located in the first country.

17. A method comprising:

receiving communication data that is directed to a first Mobile Directory Number (MDN) that is associated with a mobile communication device of a mobile subscriber, wherein the first MDN is a local telephone number in a first country, wherein the mobile communication device is associated with a second MDN, and wherein the second MDN is a local telephone number in a second country;

determining a location of the mobile communication device, wherein a first International Mobile Subscriber Identity (IMSI) number associated with the first MDN is active when the mobile communication device is located in the first country, and wherein a second IMSI number associated with the second MDN is active when the mobile communication device is located in the second country; and

routing the communication data to the mobile communication device based on the location of the mobile communication device.

18. The method of claim 17, wherein the communication data is routed to the mobile communication device via an Internet Protocol (IP) network when the second IMSI number is active.

19. The method of claim 18, wherein the mobile communication device is associated with a third MDN, wherein the third MDN is a local telephone number in a third country, and wherein a third IMSI number associated with the third MDN is active when the mobile communication device is located in the third country.

20. The method of claim 19, wherein the communication data is routed to the mobile communication device via an Internet Protocol (IP) network when the third IMSI number is active.
