The position tracking correction base station 10 sets the GPS correction value based on the coordinate set as the absolute measurement value, and compares and corrects the error of the position data of each terminal 90 received at the center center 20 to correct the correct position information. Provided to the central center 20.

The position tracking correction base station 10 is composed of a GPS antenna unit, a DGPS receiver, DGPS correction software, and the like.

The central center 20 transmits the location and status report request data to each terminal 90 through a communication means, and only the location information of the location and status data received from each terminal 90 to the location tracking correction base station 10. After transmitting and correcting the position, the exact position and situation of the terminal 90 are analyzed, and appropriate data is retrieved from the database, and then transmitted to each terminal 90 again through a communication means.

The central center 20 includes a basic geographic information system (GIS) unit on a Windows Network Terminal Server (NT) server, a database unit that manages shape information, customer information, and attribute information. And a data processing unit for analyzing and providing information, and a network unit connecting the single-specialty center 40.

The terminal 90 is composed of a central processing unit (CPU) including a GPS linked to the mobile station 80, and centralizes the location information, the situation, and the request information through a communication means at a desired time using a specialized service protocol. By receiving and transmitting with the center 20, location tracking and related additional services are provided.

The terminal 90 is composed of a GPS engine, a control unit, a switch unit, a power supply rectifying unit, and a supply unit. The terminal 90 is mounted in a mobile station 80 or a hands-free set.

The communication means transmits the GPS and the status report data from each terminal 90 interworking with the mobile station 80 to the central center 20 using a single professional service through a code division multiple access (CDMA) network. Sending and receiving, the function of each component constituting the communication means is as follows.

The mobile station (MS) 80 interworks with the terminal 90 to communicate with the base station 70 through a public network to transmit and receive call connection and traffic messages, and to connect the user to the base station 70 to perform voice conversion and incoming / outgoing calls. Performs a signal processing function for

The base station (BTS) 70 communicates with the mobile station 80 through a public network to perform call control functions such as call connection and transmission and reception of traffic data, and is connected to the control station 60 by wire and transmitted by the mobile station 80. The call connection or traffic message is transmitted to the control station 60, or the message transmitted by the control station 60 to the mobile station 80 is transmitted to the mobile station 80 through the public network. It also handles signal processing for communication with the control station 60 and maintenance with communication with the operating station.

If the central center 20 transmits the location and status report request data for requesting the current location and status report of the terminal 90 attached to each vehicle to the vehicle where each terminal 90 is located through the CDMA network, Each terminal 90 transmits the request information required by the user to the central center 20 through the CDMA network along with its location information. In addition, each terminal 90 may transmit the request information required by the user to the central center 20 together with its own location information without a request from the central center 20. In this case, the data processing flow from the terminal 90 to the central center 20 is as follows.

First, when the terminal 90 transmits a data request message (Data Request) indicating its location and situation to the mobile station 80, the mobile station 80 displays a data request response indicating a result of the data request message (Data Request). A message (Data Req Resp) is transmitted to the terminal 90, and access / traffic channel selection data is transmitted to the base station 70.

Thereafter, when the base station 70 transmits a short message transmission message SM_Send_Msg indicating transmission of a short message to the switching center 50, the switching center 50 transmits a short message point-to-point delivery message (SMDPP: Short Message Deliver). Point to Point) protocol is transmitted to the single center 40.

Next, the single professional center 40 transmits a single professional delivery message (deliver_sm) to the single professional service server 30 so that the single professional service server 30 requests from each terminal 90 to the central center 20. Send information and location information. That is, when the single expert service server 30 transmits a data request message (Data Request) indicating the location and situation of the terminal 90 to the central center 20, the central center 20 receives the received data request message (Data). A data request response message (Data Req Resp) indicating a result of the request is transmitted to the single expert service server 30.

Meanwhile, when the central center 20 extracts only the location information from the data received from the terminal 90 and transmits the location information to the location tracking correction base station 10, the location tracking correction base station 10 is corrected after the location tracking data is corrected. Announce the contents to the central center (20).

The central center 20 retrieves the information on the request from each terminal 90 and transmits the information required by the user to the position of the corrected terminal 90 through the CDMA network. Looking at the data processing flow to the terminal 90 as follows.

First, when the central center 20 transmits a data request message (Data Request) for the information requested from each terminal 90 to the single-service server 30, the single-service server 30 is a data request message ( The data request response message (Data Req Resp) indicating the result of the data request is transmitted to the central center 20, and the short message submission message (submit_sm) is transmitted to the short specialized center 40.

Thereafter, when the specialty center 40 transmits a short message point-to-point message (SMDPP) protocol to the switching center 50, the switching center 50 transmits the short-single transmission message (SM_Send_Msg) to the base station. send.

Next, when the base station 70 transmits the paging / traffic channel selection data to the mobile station 80, the mobile station 80 sends a data request message (Data Request) indicating the inquiry information from the central center 20. ), The terminal 90 transmits a data request response message (Data Req Resp) indicating a result of the data request message (Data Request) to the mobile station (80).
