第三单元
Please translate the following paage.A communication loop step by step:
通信循环的具体步骤：
VTS is started and it starts TCP listener at the specified IP and Port, and loads all VT IMEI from database;
车辆跟踪系统启动后将在指定的IP地址和端口号启动一个TCP监听程序，并从数据库中载入所有车辆跟踪器的IMEI；
The VT is powered on and comes into GPRS coverage areas, and then the VT attaches to the GPRS network and creates an active GPRS connection;
车辆跟踪器在电源启动后，如果进入GPRS覆盖范围，它就能接入GPRS网络并且激活GPRS连接；The VT creates a TCP connection to the fixed IP and Port, and VTS gets the connection request at the listener and accepts the connection;
车辆跟踪器创建一个TCP连接到固定的IP地址和端口，车辆跟踪系统在监听端收到连接请求并接受该连接；
The VT sends login meage, when the IMEI of the VT is sent as the id, VTS verifies IMEI and decides to accept or reject this connection;
车辆跟踪器发送登录消息，以IMEI作为身份码，车辆跟踪系统验证IMEI并决定接受还是拒绝该连接；
Connection is set up, and VT sends Location Record in T-TCP protocol to the VTS;
连接建立后，车辆跟踪器通过T-TCP协议向车辆跟踪系统发送位置记录；
The VTS gets Location Record, sends location to G-Tech Server by GTHttpRequest cla, and gets return in XML format;
车辆跟踪系统收到位置记录并将其通过GTHttpRequest类发送给G-Tech服务器，再接收XML格式的返回信息；
The VTS procees the returned addre info from G-Tech Server and sends addre info to the LCS;车辆跟踪系统处理G-Tech服务器返回的地址信息，并将其发送给位置信息收集系统；
If the LCS needs to send command to the VTS, the VTS will encode command and send encoded command to the particular VT.如果位置信息收集系统需要向车辆跟踪系统发出命令，车辆跟踪系统会对命令进行编码，然后将编码后的命令发送给特定的车辆跟踪器。
