  • Patent number: 10986484
    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.

  • Patent number: 10939403
    Abstract: Aspects of the subject disclosure may include, for example, a system that provides a first message to a communication device that includes a temporary international mobile subscriber identity (IMSI) to be provisioned onto the device. A first registration message is sent to a registration function server, wherein the server includes a registry, wherein the first registration message indicates to the server to add the temporary IMSI to the registry. A second registration message is sent to the server in response to detecting expiration of a limited time period, wherein the second registration message indicates to the server to remove the temporary IMSI from the registry. A second message is provided to the wireless communication device that indicates to the wireless communication device the expiration of the limited time period, and that the temporary IMSI is removed from the registry of the registration function server. Other embodiments are disclosed.
