OBU(On Board unit, board units) network element, finish the transmitting-receiving of custom end intelligent traffic system business datum, the carrying of the various functions of client.
When specific implementation, can provide human-computer interaction interface by operating platform, monitor, visit each network element.Can also make things convenient for remote access and control by increasing web server.
The embodiment of the invention is taked flat networking mode, is intended to communicate by letter between one-hop realization network element, makes that the entire system reaction is quicker.For this reason, the logic interfacing that designs between each network element of the present invention comprises: RSU and OME control port, RSU and SCG control port, RSU and RME control port, RSU and aaa server control port, OME and SCG control port, RME and OME control port, RSU and RSU control port, OBU and OME control port, OBU and aaa server control port, OBU and SCG control port, OBU and RSU control port, SCG and RME control port, OME and aaa server control port, RME and aaa server control port.
Simultaneously, be the unique port numbers of the configuration of the control port between said network element.By corresponding port, can adopt TCP or udp protocol to communicate between each network element.Wherein, point-to-point communication can adopt TCP or UDP mode, needs the message of broadcasting to adopt UDP multicast mode.
Embodiment of the invention design message transmitted between each network element comprises message header and message body at least.For some message, message body can be sky.
Preferably, described message can also comprise check code, is used for whole message is carried out verification.In a concrete application example, check code refers to and can with back one byte XOR, up to the previous byte of check code, take a byte from message header.
Preferably, described message can also comprise message-length, the total length of described message-length indication overall message.For example, when described message comprised message header, message body and check code, described message-length was indicated this total length.
Preferably, carry message identifier in the embodiment of the invention design message header, described message identifier comprises interface type sign (ID) and type of message sign (ID), thereby it is more specific to make that interface more enriches.
Wherein, described interface type sign is used to indicate the interface that message is sent out transmission
For example, in the present invention's one application example, can the design interface type as follows:
OBU and RSU interface ID:1
