1. Overview

1.1. Scope of This Document

The @Track Air Interface Protocol is a digital communication interface based on printable ASCII characters over SMS or GPRS which is used for all communication between the backend server and the terminal. The backend server sends a command to the terminal and then the terminal confirms with an acknowledgement message. If necessary, the terminal also sends report messages to the backend server.

The purpose of this document is to describe how to build up the backend server based on the

@Track Air Interface Protocol.

+ACK:GTXXX,<parameter1>,<parameter2>,…$

+RESP:GTXXX,<parameter1>,<parameter2>,…$

Message type

Command

Acknowledgement

Report

The entire message string ends with character „$‟.

The characters „XXX‟ identify the deferent message.

The “<parameter1>,<parameter2>,…” carry the message‟s parameters. The number of parameters is different in different messages. The ASCII character „,‟ is used to separate the neighbouring parameter characters. The parameter string may contain the ASCII characters:

„0‟–„9‟, ‟a‟–„z‟, ‟A‟–„Z‟.

Detailed descriptions of each message format are located in the specific message sections.

By sending Commands to the terminal, the backend server can either configure and query the parameters of the terminal or control the terminal to perform specific actions. When the terminal

3.2.2. Backend Server Register Information

The command AT+GTSRI is used to configure where and how to report all the messages, including the server information and the communication method between the backend server and the terminal. When the terminal is configured correctly, it should be able to report data to the backend server.

 AT+GTSRI=

Example:

AT+GTSRI=gmt100,3,,1,116.226.44.17,7011,116.226.45.229,7012,+8613812341234,15,1,,,,,

 <Report Mode>: This defines the communication method between the backend server and the terminal. Supported report modes as following:

TRACGMT100AN001

– 11 –


 0: Stop reporting.

 1: TCP short-connection preferred mode. The connection is based on TCP protocol.

The terminal connects to the backend server every time it needs to send data and will shut down the connection when the terminal finishes sending data. And if it fails to establish TCP connection to the backend server (both Main Server and Backup

Server), it will try to send data via SMS to the SMS gateway.

 2: TCP short-connection forced mode. The connection is based on TCP protocol. The terminal connects to the backend server every time it needs to send data and will shut down the connection when the terminal finishes sending data. And if it fails to establish TCP connection to the backend server (both Main Server and Backup

Server), it will store the data in the memory buffer if buffer report function is enabled.

Otherwise the data is dropped.

 3: TCP long-connection mode. The connection is based on TCP protocol. The terminal connects to the backend server and maintains the connection using the heart beat data. The backend server should respond to the heart beat data from the terminals.

 4. UDP mode. The terminal will send data to the backend server by UDP protocol.

Receiving protocol commands via UDP is supported if the GPRS network allows it. It is recommended to enable heartbeat sending and +RESP:GTPDP report when UDP receiving is the case.

 5: Force on SMS. Only use the SMS for transmitting.

 6: UDP with fixed local port. Like the UDP mode, the terminal will send data using

UDP protocol. The difference is the terminal will use fixed local port rather than

 random port to communicate with the server in this mode. Thus the backend server could use identical port to communicate with all terminals if the backend server and the terminals are all in the same VPN network. The port number the device uses is the

Queclink enabled, if the device goes into areas without GSM/GPRS network covering, it will stores all report locally. When the device goes back to areas with GSM/GPRS network covering, it will then send all the buffered reports through GPRS.

 0: Disable the buffer report function.





Confidential device will send all the buffered messages before sending any normal message except for the SOS message (+RESP:GTSOS).

 <Main Server IP / Domain Name>: The IP address or the domain name of the primary server.

 <Main Server Port>: The port of the primary server.

 <Backup Server IP>: The IP address of the backup server.

 <Backup Server Port>: The port of the backup server.

 <SMS Gateway>: Maximum 20 characters including the optional national code starting with

“+” for SMS messages sending. Short code (for example: 10086) is also supported.

 <Heartbeat Interval>: the interval of sending heartbeat package message (+ACK:GTHBD)

TRACGMT100AN001

– 12 –

GMT00 @Track Air Interface Protocol when report mode is TCP long-connection mode or UDP mode. If set to 0, no heartbeat package message sending.

 <SACK Enable>: This defines whether the backend server should respond to the terminal with SACK message when receiving messages from the terminal.

 0: the backend server does not reply SACK message after receiving message from the terminal.

 1: the backend server replies SACK message when receiving any message from the terminal.

The acknowledgment message of AT+GTSRI command:

 +ACK:GTSRI,

3.2.16. Harsh Behavior Monitoring

The command AT+GTHBM is used to monitor the harsh behavior of drive with GPS. Two harsh behaviors are monitored, the harsh braking and the harsh acceleration. According the speed read from GPS, 3 levels of speed are defined including high speed, medium speed and low speed. For each speed level, 2 thresholds of speed change are defined to determine the harsh braking and harsh acceleration. If the change of speed within 5 seconds are greater than the corresponding threshold, the device will report +RESP:GTHBM message to the backend server to indicate the harsh behavior. The same harsh behavior within 30 seconds only reports once. For this function to work, the <GPS on Need> in AT+GTCFG must set to 0.

3.3. Report

This section defines the formats of the report messages. Due to the max length of SMS message

(160 bytes), it is recommended to carefully set the <Report Composition Mask> in AT+GTCFG to limit the length of the report which contains GPS position information if you choose SMS as the transmit method. Otherwise the report will be truncated to fit the length of SMS message.

3.3.1. Position Related Report

 +RESP:GTTOW,

If the tow alarm is enabled by the command AT+GTTOW, the device will send the message

+RESP:GTTOW to the backend server when the motion sensor detects tow.

 +RESP:GTDIS,

If the status of digital inputs are detected being changed, the device will send the message

+RESP:GTDIS to the backend server.

 +RESP:GTIOB,

If the IO combination is set and the corresponding condition appears, the device will report the message +RESP:GTIOB to the backend server.

 +RESP:GTGEO,

If Geo-Fence is configured and enabled, the device will send the message +RESP:GTGEO to the backend server according to settings when the device enters or exits the Geo-Fence.

3.3.5. Buffer Report

If the buffer report function is enabled by command AT+GTSRI, the terminal will save the report messages in a local buffer when the following occurs.

 GSM network is not available

 Failed to activate GPRS context for the TCP or UDP connection.

 Failed to establish the TCP connection with the backend server.

These messages will be sent to the backend server when connection to the server recovers again.

The buffer reports are saved to the built-in non-volatile memory in case the device is reset. The terminal can buffer up to 3000 messages (160 bytes per message).

Detailed information about buffer report is listed below.

 Only +RESP messages are buffered except that +RESP:GTALL is not buffered

 In the buffer report, the original header string “+RESP” is replaced by “+BUFF” while keeps the other content untouched including the original sending time and count number.

 Buffered messages will be sent only via GPRS by TCP or UDP protocol. They cannot be sent via SMS. If the current report mode is forcing on SMS, the buffered messages will be sent via TCP short connection.

 The buffered messages will be sent after the other normal messages sending if <Buffer

Mode> in AT+GTSRI is set to 1.

 The buffered messages will be sent before the other normal messages sending if <Buffer

Mode> in AT+GTSRI is set to 2. The SOS message has the highest priority and is sent before the buffered messages.
