  • Patent number: 10602345
    Abstract: Aspects of the subject disclosure may include, for example, communication device, including a universal integrated circuit card that stores a provisioned, shared international mobile subscriber identity (IMSI), having a processing system that accesses the universal integrated circuit card to determine the shared IMSI using a secret key, wherein the secret key is uniquely associated with the universal integrated circuit card. A second IMSI is received via an over-the-air interface responsive to a first registration request that includes the shared IMSI and identification information obtained by an identity function of the network. The second IMSI is stored in the universal integrated circuit card, wherein the second IMSI facilitates a registration process that registers the communication device with the network, and wherein registration of the communication device facilitates access to subscriber services for the communication device. Other embodiments are disclosed.

  • Publication number: 20190274029
    Abstract: Aspects of the subject disclosure may include, for example, a system that receives a notification, from an identity proxy function, indicating an identity mobile subscriber identity (IMSI) is being registered. That is, a communication device sends a registration request that includes the IMSI to a first registration function. Further, the identity proxy function intercepts the registration request and sends the first notification to the device. Also, the system, sends a first registration message to the first registration function. The first registration function includes a first registry. Further, the first registration message indicates to the first registration function to add the IMSI to the first registry. The system also sends a second registration message to a second registration function. The second registration function includes a second registry. Further, the second registration message indicates to the second registration function to remove the IMSI to the first registry.
