Abstract: A traffic statistics collection method and device applied to an in-vehicle service interaction system includes, when an in-vehicle infotainment (IVI) system performs a first service, communicating, by a telematics box (T-box), with the IVI using a first private Internet Protocol (IP) address, and communicating, by the T-box, with a telematics service provider (TSP) using a first access point name (APN) and a first external IP address corresponding to the first private IP, and when the IVI performs a second service, communicating, by the T-box, with the IVI using a second private IP address, and communicating, by the T-box, with the TSP using a second APN and a second external IP address corresponding to the second private IP address.
