CONNECTION BETWEEN SIM-LESS DEVICE AND CELLULAR NETWORK - A simplified explanation of the abstract

This abstract first appeared for US patent application 18264677 titled 'CONNECTION BETWEEN SIM-LESS DEVICE AND CELLULAR NETWORK

Simplified Explanation

- Systems, methods, and software for directly connecting a SIM-less device with a cellular network. - User Equipment (UE) with a SIM provisioned with multiple subscription profiles for the cellular network. - UE establishes direct communication with a SIM-less device without a subscription. - UE assigns a temporary subscription from the SIM to the SIM-less device. - UE transmits subscription credentials to the SIM-less device for registration with the cellular network. - SIM-less device can then establish a direct connection with the cellular network using the temporary subscription.

Potential Applications

- IoT devices without SIM cards can connect to cellular networks. - Temporary access for devices in emergency situations. - Testing and development of new devices on cellular networks.

Problems Solved

- Allowing SIM-less devices to access cellular networks. - Providing temporary subscriptions for devices without their own SIM cards.

Benefits

- Increased flexibility for connecting devices to cellular networks. - Simplified process for temporary access to cellular networks. - Enhanced capabilities for IoT devices without SIM cards.

Original Abstract Submitted

Systems, methods, and software of directly connecting a SIM-less device with a cellular network. In one embodiment, User Equipment (UE) includes a Subscriber Identity Module 5 (SIM) provisioned with a plurality of subscription profiles for subscriptions to the cellular network. The UE establishes a direct communication with a SIM-less device that does not have a subscription with the cellular network. The UE selects one of the subscriptions provisioned in the SIM as a temporary subscription assigned to the SIM-less device to allow the SIM-less device to establish a direct connection with the cellular network using the 10 temporary subscription, and transmits a message to the SIM-less device via the direct communication containing subscription credentials for the temporary subscription. The SIM-less device may therefore register with the cellular network using the subscription credentials provided by the UE, and establish a direct connection with the cellular network using the temporary subscription.
