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.
