Abstract

Aspects of the subject disclosure may include, for example, a system that manages utilization of mobile subscriber identity information including enabling use of such information by different communication devices. The use of the same mobile subscriber identity information by multiple devices can be based on locations and other mobile subscriber identity information can be assigned to devices based on the locations. Other embodiments are disclosed.

First claim

What is claimed is:

1. A method comprising:
receiving, by an identity proxy function executed by a processing system including a processor, a first international mobile subscriber identity associated with a registration request by a first communication device, wherein the first international mobile subscriber identity is associated with the first communication device;
determining whether the first international mobile subscriber identity is included in a group of international mobile subscriber identities that are shared with other communication devices;
responsive to a first determination that the first international mobile subscriber identity is included in the group of international mobile subscriber identities, simulating, by the identity proxy function, a registration of the first communication device resulting in a simulated registration;
determining, by the identity proxy function from the simulated registration, whether the first communication device is associated with a particular location; and
responsive to a second determination that the particular location is a first location, transmitting, by the identity proxy function, an authentication request to a first registration function, wherein the first registration function stores first subscriber information including the first international mobile subscriber identity that is indexed to the first communication device, wherein a second registration function stores second subscriber information including the first international mobile subscriber identity that is indexed to a second communication device that shares the first international mobile subscriber identity, wherein the second registration function is associated with a second location and does not store the first subscriber information, wherein the first registration function is associated with the first location and does not store the second subscriber information, and wherein the transmitting of the authentication request to the first registration function enables the first communication device to complete a registration process.

2. The method of claim 1 , wherein the processing system is selected from a group of processing systems based on the first location, wherein the first and second communication devices have different secret keys, and wherein a first secret key of the first communication device is utilized in the registration process.

3. The method of claim 2 , wherein the first communication device is a non-mobile device.

4. The method of claim 3 , wherein the non-mobile device is a machine-to-machine communication device.

5. The method of claim 1 ,
wherein the transmitting of the authentication request to the first registration function is performed without the simulating of the registration responsive to a third determination that the first international mobile subscriber identity is not included in the group of international mobile subscriber identities.

6. The method of claim 1 , wherein the processing system operates as a visitor location register, wherein the visitor location register is selected from a group of visitor location registers based on a registration service area of the visitor location register, wherein the first registration function comprises a home location register, and wherein the authentication request comprises a first request to verify the first international mobile subscriber identity and a second request for authentication triplets.

7. The method of claim 6 , further comprising:
responsive to a third determination that the particular location is not the first location, reassigning a second international mobile subscriber identity to the first communication device.

8. The method of claim 7 , wherein the reassigning of the second international mobile subscriber identity to the first communication device is via an over-the-air interface.

9. The method of claim 8 , wherein the over-the-air interface utilizes a transport key that is stored by the first communication device and is not stored by the second communication device.

10. The method of claim 1 , wherein the processing system operates as a mobility management entity, wherein the mobility management entity is selected from a group of mobility management entities based on a registration service area of the mobility management entity, wherein the first registration function comprises a home subscriber server, and wherein the authentication request comprises a first request to verify the first international mobile subscriber identity and a second request for authentication vectors.

11. The method of claim 10 , further comprising:
responsive to a third determination that the particular location is not the first location, reassigning a second international mobile subscriber identity to the first communication device.

12. The method of claim 11 , wherein the reassigning of the second international mobile subscriber identity to the first communication device is via an over-the-air interface.

13. The method of claim 12 , wherein the over-the-air interface utilizes a transport key that is stored by the first communication device and is not stored by the second communication device.

14. A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processing system of a first communication device that includes a processor, facilitate performance of operations, comprising:
providing a first international mobile subscriber identity to an identity proxy function being executed by a network server, wherein the first international mobile subscriber identity is associated with a registration request by the first communication device, wherein the first international mobile subscriber identity is associated with the first communication device;
receiving a simulated request from the identity proxy function, wherein the simulated request is generated during a simulated registration, wherein the simulated registration is initiated responsive to a first determination that the first international mobile subscriber identity is included in a group of international mobile subscriber identities that are shared with other communication devices;
responsive to the simulated request, providing an authentication response to the identity proxy function, wherein the providing the authentication response enables the identity proxy function to perform a second determination that the first communication device is associated with a first location, wherein the providing the authentication response enables the identity proxy function to transmit an authentication request to a first registration function, wherein the first registration function stores first subscriber information including the first international mobile subscriber identity that is indexed to the first communication device, wherein a second registration function stores second subscriber information including the first international mobile subscriber identity that is indexed to a second communication device that shares the first international mobile subscriber identity, wherein the second registration function is associated with a second location and does not store the first subscriber information, wherein the first registration function is associated with the first location and does not store the second subscriber information; and
facilitating a registration process that enables the first communication device to access communication services.

15. The non-transitory machine-readable storage medium of claim 14 , wherein the first and second communication devices have different secret keys, and wherein a first secret key of the first communicatio
