  • 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.

  • Patent number: 10892948
    Abstract: Concepts and technologies are disclosed herein for creating and using service control functions. The service control functions can detect a message via an adapter function. The message can relate to a service controlled by the service control functions. Service policies can be accessed. The service policies can include message handling policies and can be accessed to determine if a policy relating to the message exists. If a determination is made that the policy exists, the message and the policy can be analyzed to determine an action to take with respect to the message, and the action can be initiated.

  • Publication number: 20200403970
    Abstract: Concepts and technologies are disclosed herein for providing network address translation in a software defined networking environment. A control system can detect a request to create a network address translation function. The control system can analyze a recipe to identify a network address translation switch and a network address translation virtual function that are to provide functionality of the network address translation function, trigger instantiation of the network address translation switch via a network control function, and trigger instantiation of the network address translation virtual function via a service control function. The control system can validate the network address translation function and chain the network address translation function to a host. The network address translation function can provide address translation for the host using the network address translation switch.

  • Patent number: 10834576
    Abstract: A system is described that can perform a method for providing a first mobile network operator system with information relating to configuration data. The configuration data enables management of content and memory allocation for security domain containers of a universal integrated circuit card of a communication device. Security management of the universal integrated circuit card is delegated by providing the configuration data to a second mobile network operator system to enable management of the content and the memory allocation for the security domain containers. The memory allocation is adjusted by the second network mobile operator system according to a second group of services provided to the communication device.

  • Publication number: 20200329375
    Abstract: A system that incorporates the subject disclosure may include, for example, instructions which when executed cause a device processor to perform operations comprising sending a service request to a remote management server; receiving from the management server an authentication management function and an encryption key generator for execution by a secure element and an encryption engine for execution by a secure device processor, sending a request to establish a communication session with a remote device; and communicating with the remote device via a channel established using an application server. The secure element and the secure device processor authenticate each other using a mutual authentication keyset. The secure element, the secure device processor and the device processor each have a security level associated therewith; the security level associated with the secure device processor is intermediate between that of the secure element and that of the device processor.
