Abstract

Provided herein is a protocol communication method between a user terminal and the base station of a vehicle network system so as to easily provide a driver with pieces of information provided by an in-vehicle wireless sensor network system via the user terminal. A protocol communication method for a vehicle network system according to a first embodiment includes receiving, by the base station, a command message from the user terminal, receiving, by the base station, information responding to the command message from one or more vehicle wireless sensor nodes and/or an in-vehicle wired network, and sending, by the base station, a state message to the user terminal, based on the received information.

First claim

What is claimed is:

1 . A protocol communication method for a vehicle network system, the method being configured such that a base station installed in a vehicle communicates with a user terminal, comprising:
receiving, by the base station, a command message from the user terminal; receiving, by the base station, information responding to the command message from one or more vehicle wireless sensor nodes and/or an in-vehicle wired network; and sending, by the base station, a state message to the user terminal, based on the received information.

2 . The protocol communication method of claim 1 , wherein:
the command message and the state message include in common a control field and a data field, and the control field includes a message type sub-field and a control type sub-field.

3 . The protocol communication method of claim 2 , wherein the command message is configured such that:
the message type sub-field of the control field is fixed at a first value, and a type of command is determined depending on a value of the control type sub-field.

4 . The protocol communication method of claim 2 , wherein the state message is configured such that:
the message type sub-field of the control field is fixed at a second value, and the data field includes state information of the one or more wireless sensor nodes and/or state information of the wired network.

5 . A protocol communication method for a vehicle network system, the method being configured such that a base station installed in a vehicle communicates with a user terminal, comprising:
receiving, by the base station, a command message from the user terminal; receiving, by the base station, information responding to the command message from one or more vehicle wireless sensor nodes and/or an in-vehicle wired network; and sending, by the base station, a data message to the user terminal, based on the received information.

6 . The protocol communication method of claim 5 , wherein:
the command message and the data message include in common a control field and a data field, and the control field includes a message type sub-field and a control type sub-field.

7 . The protocol communication method of claim 6 , wherein the command message is configured such that:
the message type sub-field of the control field is fixed at a first value, and a type of command is determined depending on a value of the control type sub-field.

8 . The protocol communication method of claim 6 , wherein the data message is configured such that:
the message type sub-field of the control field is fixed at a third value, and the data field includes sensor information of the one or more wireless sensor nodes and/or vehicle information.

9 . A vehicle network system, comprising:
one or more wireless sensor nodes installed inside and/or outside of a vehicle; a wired network installed inside of the vehicle; and a base station configured to receive a command message from a user terminal, receive information responding to the command message from the one or more wireless sensor nodes and/or the wired network, and send a state message or a data message to the user terminal based on the received information.

10 . The vehicle network system of claim 9 , wherein:
the command message, the state message, and the data message include in common a control field and a data field, and the control field includes a message type sub-field and a control type sub-field.

11 . The vehicle network system of claim 10 , wherein the command message is configured such that:
the message type sub-field of the control field is fixed at a first value, and a type of command is determined depending on a value of the control type sub-field.

12 . The vehicle network system of claim 10 , wherein the state message is configured such that:
the message type sub-field of the control field is fixed at a second value, and the data field includes state information of the one or more wireless sensor nodes and/or state information of the wired network.

13 . The vehicle network system of claim 10 , wherein the data message is configured such that:
the message type sub-field of the control field is fixed at a third value, and the data field includes sensor information of the one or more wireless sensor nodes and/or vehicle information.
