Enhanced Subscriber Identity Module (ESIM) Remote Provisioning Based Solution to Provide IMS Services to a User of a Private Network (NPN) - A simplified explanation of the abstract

This abstract first appeared for US patent application 17917161 titled 'Enhanced Subscriber Identity Module (ESIM) Remote Provisioning Based Solution to Provide IMS Services to a User of a Private Network (NPN)

Simplified Explanation

The patent application describes a system where User Equipment (UEs) connected to a Standalone Non-Public Network (SNPN) can receive Internet Protocol Multimedia Subsystem (IMS) and emergency services. This is achieved by using an Enhanced Subscriber Identity Module (eSIM) to onboard access IMS credentials needed by the UEs to access those services. The network nodes in the SNPN, such as a Session Management Function (SMF) and a Unified Data Management (UDM) function, are also configured to support the onboarding of the credentials to the UEs. The process involves the UE receiving remote provisioning information from a SMF, initiating a remote provisioning procedure, and receiving Internet access IMS subscription data needed to establish a Packet Data Unit (PDU) session with an IMS network.

  • UEs connected to a Standalone Non-Public Network (SNPN) can receive IMS and emergency services.
  • Enhanced Subscriber Identity Module (eSIM) is used to onboard access IMS credentials.
  • Network nodes in the SNPN, such as Session Management Function (SMF) and Unified Data Management (UDM) function, support the onboarding process.
  • UE receives remote provisioning information from SMF.
  • UE initiates a remote provisioning procedure to establish a PDU session with an IMS network.

Potential Applications

  • This technology can be used in private networks, such as industrial or enterprise networks, to provide IMS and emergency services to connected devices.
  • It can be applied in critical infrastructure systems, where reliable and secure access to IMS services is essential.
  • The system can be used in smart cities, enabling connected devices to access IMS and emergency services seamlessly.

Problems Solved

  • The technology solves the problem of enabling UEs in a Standalone Non-Public Network to access IMS and emergency services.
  • It addresses the challenge of securely onboarding access IMS credentials to UEs using an Enhanced Subscriber Identity Module (eSIM).
  • The system solves the issue of establishing a Packet Data Unit (PDU) session with an IMS network in a remote provisioning procedure.

Benefits

  • The technology provides UEs in a Standalone Non-Public Network with access to IMS and emergency services, enhancing their functionality and connectivity.
  • The use of an Enhanced Subscriber Identity Module (eSIM) simplifies the onboarding process for accessing IMS credentials.
  • The system enables remote provisioning, allowing UEs to establish a PDU session with an IMS network without physical interaction.
  • It improves the reliability and security of accessing IMS services in private networks.


Original Abstract Submitted

User Equipment (UEs) () connected to a Standalone Non-Public Network (SNPN) () receive Internet Protocol Multimedia Subsystem (IMS) and emergency services by using an Enhanced Subscriber Identity Module (e SIM) to onboard access IMS credentials needed by the UEs to access those services. Network nodes in the SNPN, such as a Session Management Function (SMF) () and a Unified Data Management (UDM) function () are also configured to support the onboarding of the credentials to the UEs. In particular, a UE receives remote provisioning information from a SMF. Upon receipt, the UE initiates a remote provisioning procedure and receives Internet access IMS subscription data needed to establish a Packet Data Unit (PDU) session with an IMS network.
