Information converting method and system thereof

An information converting system, which is configured to convert a first information from a first device into a second information and transmit the second information to a second device, and the information converting system comprising:

• the first device generating the first information corresponding to a first communication protocol, wherein the first information comprises a first access layer sub-information and an upper-layer protocol sub-information;
• and
• a converter connected to the first device and receiving the first information, and comprising:
• a storing module configured to access the first information and a converting process;
• and
• a processing module connected to the storing module, wherein the processing module is configured to implement an information converting method comprising:
• performing a first access layer removing step to remove the first access layer sub-information from the first information according to the converting process;
• and
• performing a second access layer adding step to add a second access layer sub-information corresponding to a second communication protocol to the first information and combine the second access layer sub-information with the upper-layer protocol sub-information according to the converting process so as to convert the first information into the second information, wherein the second information corresponds to the second communication protocol;
• wherein the first communication protocol is one of a Dedicated Short Range Communication (DSRC) standard and a Cellular Vehicle-to-Everything (C-V2X) standard, the second communication protocol is the other one of the DSRC standard and the C-V2X standard, and the first communication protocol and the second communication protocol are different from each other;
• wherein the converter is constructed in a field using either the first communication protocol or the second communication protocol and transmits the second information to the second device, and the field refers to a vehicle-road communication or a vehicle-to-vehicle communication;
• wherein one of the first device and the second device is a Roadside Unit (RSU) and the other one of the first device and the second device is an On Board Unit (OBU), or both the first device and the second device are the OBU.
