System for integrating heterogeneous wireless networks, edge-computing apparatus and method for operating the same

A method for operating integration of heterogeneous wireless networks, comprising:

• in an in-vehicle device, performing a handover process and establishing a second wireless connectivity with a mobile base station for transmitting data generated by one or more peripheral devices installed in a vehicle or a minority of items of the data to a mobile core control plane network;
• in the handover process, switching the second wireless connectivity to a first wireless connectivity with a wireless access point in response to a signal strength indicator indicating that signal strength of the first wireless connectivity is higher than a preset threshold or signal strength of the second wireless connectivity;
• in the in-vehicle device, transmitting the data to an edge-computing device over the first wireless connectivity;
• in the edge-computing device, a switch receiving the first wireless networking data via a first wireless network interface and shifting the second wireless networking data via a shifted connectivity to the edge-computing device from the mobile core control plane network via a second wireless network interface;
• in the switch, performing network convergence on the first wireless networking data and the second wireless networking data so as to obtain a converged data;
• in a streaming proxy of the edge-computing device, performing source switching on the converged data received from the switch without interruption during the handover process by assigning a common IP address to the converged data;
• and
• in the edge-computing device, storing the converged data with the common IP address to a data bank.

An edge-computing device, installed in a vehicle station, comprising:

• a switch being configured to receive a first wireless networking data from an in-vehicle device installed in a vehicle via a first wireless network interface and a second wireless networking data that is transmitted by the in-vehicle device and is shifted via a shifted connectivity from a mobile core control plane network via a second wireless network interface;
• wherein the switch performs network convergence on the first wireless networking data and the second wireless networking data so as to obtain a converged data;
• a streaming proxy coupled with the switch and being configured to perform source switching on the converged data received from the switch without interruption during a handover process performed by the in-vehicle device by assigning a common IP address to the converged data;
• and
• a data bank being configured to store the converged data with the common IP address.
