COMMUNICATION METHOD AND COMMUNICATION DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240223548 titled 'COMMUNICATION METHOD AND COMMUNICATION DEVICE

The communication method and device described in this patent application enable a terminal device to perform authentication even when the second authentication device is not deployed in the second network.

Mobility management device obtains first information of a terminal device, including a home network identifier and/or a routing indicator.
First information prompts the mobility management device to select a second authentication device of a second network for authentication.
Credential of the terminal device belongs to the second network, and the second authentication device is not deployed in the second network.
Mobility management device selects a first authentication device based on the first information, both belonging to a first network.

Potential Applications: - Secure authentication processes in networks with limited authentication devices. - Enhancing network security by enabling authentication even when specific authentication devices are not available.

Problems Solved: - Overcoming limitations in network authentication when specific authentication devices are not deployed. - Providing a reliable authentication method for terminal devices in various network environments.

Benefits: - Improved network security and authentication processes. - Enhanced flexibility for terminal devices to authenticate in different network scenarios.

Commercial Applications: Title: Enhanced Network Authentication Method for Terminal Devices This technology can be applied in telecommunications, IoT devices, and network security industries to enhance authentication processes and improve overall network security.

Questions about the technology: 1. How does this technology improve network security in diverse network environments? 2. What are the potential implications of this innovation on the telecommunications industry?

Original Abstract Submitted

embodiments of this application provide a communication method and a communication device. the communication method includes: a mobility management device obtains first information of a terminal device, where the first information includes a home network identifier and/or a routing indicator that are/is of the terminal device, the first information indicates the mobility management device to select a second authentication device of a second network, a credential of the terminal device belongs to the second network, and the second authentication device is not deployed in the second network. the mobility management device selects a first authentication device based on the first information, where the first authentication device and the mobility management device belong to a first network. according to the method, in this application, the terminal device can be enabled to perform authentication when the second authentication device is not deployed in the second network.
