Abstract

A communication system and a comparison method for securing a communication path for a legitimate user via a terminal apparatus (“TA”). A vehicle-mounted communication device (“VMCD”) transmits a device ID identifying the VMCD to a TA, acquires a terminal ID from the TA, and transmits the device ID and the terminal ID acquired from the TA to a central apparatus. The TA transmits a terminal ID identifying the TA to the VMCD, acquires a device ID from the VMCD, and transmits the terminal ID and the device ID acquired from the VMCD to the central apparatus. The central apparatus receives a device ID and a terminal ID transmitted from the VMCD and a device ID and a terminal ID transmitted from the TA, and compares the device ID and the terminal ID received from the VMCD with the device ID and the terminal ID received from the TA.

Claims12

Dependent claims

A communication system including a vehicle-mounted communication device connected to a communication network in a vehicle, a terminal apparatus detachably connected to the vehicle-mounted communication device, and a central apparatus that is connected to a communication network outside the vehicle and that can communicate with the terminal apparatus,

wherein the vehicle-mounted communication device includes:
a means for storing a device ID for identifying the vehicle-mounted communication device;
a means for transmitting the device ID to the terminal apparatus;
a means for acquiring, from the connected terminal apparatus, a terminal ID for identifying the terminal apparatus;
and
a means for transmitting the device ID and a terminal ID that was acquired from the terminal apparatus to the central apparatus via the terminal apparatus,
the terminal apparatus includes:
a means for storing a terminal ID for identifying the terminal apparatus;
a means for transmitting the terminal ID to the vehicle-mounted communication device;
a means for acquiring a device ID transmitted from the vehicle-mounted communication device;
and
a means for transmitting the terminal ID and a device ID that was acquired from the vehicle-mounted communication device to the central apparatus, and
the central apparatus includes:
a means for receiving a device ID and a terminal ID that were transmitted from the vehicle-mounted communication device and a device ID and a terminal ID that were transmitted from the terminal apparatus;
and
a comparison means for comparing the device ID and the terminal ID that were received from the vehicle-mounted communication device with the device ID and the terminal ID that were received from the terminal apparatus.

13 more elements

A comparison method of comparing a vehicle-mounted communication device connected to a communication network in a vehicle with a terminal apparatus detachably connected to the vehicle-mounted communication device using a central apparatus that is connected to a communication network outside the vehicle and that can communicate with the terminal apparatus,

wherein the vehicle-mounted communication device is configured to:
transmit a device ID for identifying the vehicle-mounted communication device to the terminal apparatus,
acquire, from the connected terminal apparatus, a terminal ID for identifying the terminal apparatus, and
transmit the device ID and a terminal ID that was acquired from the terminal apparatus to the central apparatus via the terminal apparatus,
the terminal apparatus is configured to:
transmit a terminal ID for identifying the terminal apparatus to the vehicle-mounted communication device,
acquire a device ID transmitted from the vehicle-mounted communication device, and
transmit the terminal ID and a device ID that was acquired from the vehicle-mounted communication device to the central apparatus, and
the central apparatus is configured to:
receive a device ID and a terminal ID that were transmitted from the vehicle-mounted communication device and a device ID and a terminal ID that were transmitted from the terminal apparatus, and
compare the device ID and the terminal ID that were received from the vehicle-mounted communication device with the device ID and the terminal ID that were received from the terminal apparatus.
