Virtual CPE Tunneling via Authentication Server

The patent introduces an authentication server as an intermediary between the terminal and the network. The authentication server manages terminal registration and provides authentication information to virtual CPEs, eliminating the need for complex VPN settings at the terminal side. The virtual CPE uses the authentication information from the server to establish connections, simplifying the overall system while maintaining outside-home access capability.

The authentication server acts as a trusted intermediary that enables terminals to access services outside the home through a controlled authentication mechanism rather than requiring VPN tunneling. This approach maintains communication quality by using the communication service provider's own authentication infrastructure, ensuring reliable and high-quality connections while providing outside-home access.

The system implements self-service functionality where the authentication server automatically manages terminal registration and generates authentication information. When a terminal connects to a virtual CPE, the server automatically provides the necessary authentication credentials, eliminating the need for manual VPN configuration. This automated approach significantly improves ease of operation while maintaining external service connectivity.

The authentication server performs multiple functions: it registers terminal information, generates authentication information, and enables tunnel connection establishment. By consolidating these functions into a single multi-functional component, the system achieves simple connection establishment without requiring separate complex authentication infrastructure, as the same server handles all authentication and registration tasks.
