Core Network Mediation for Cross-Vendor Zero-Power Communication

The patent introduces a core network element as an intermediary to enable non-direct communication between terminal devices. Instead of requiring devices to establish direct private interfaces, the core network element mediates the communication by receiving information from one terminal device and forwarding it to another terminal device through the user plane. This resolves the contradiction by enabling intercommunication between devices from different manufacturers while avoiding the complexity of private interfaces.

The patent makes the core network element universal by enabling it to handle non-direct communication for terminal devices from different manufacturers. The core network element performs multiple functions: receiving first information from a first terminal device, determining a second core network element, receiving second information from the second core network element, and forwarding it to the second terminal device. This multi-functionality eliminates the need for manufacturer-specific private interfaces.

The core network element acts as a mediator that eliminates the need for terminal devices to implement complex private interfaces. The intermediary handles the communication routing and information forwarding, simplifying the terminal device design and reducing manufacturing costs. Deployment costs are reduced because the solution leverages existing core network infrastructure rather than requiring new private interface implementations at every terminal.

The patent enables terminal devices to perform self-service by allowing them to send information about themselves through the user plane without requiring special private interface configurations. The core network element automatically determines the appropriate second core network element and forwards the information, eliminating the need for manual configuration and reducing deployment complexity and cost.
