TECHNICAL FOR TRANSMITTING AND RECEIVING DATA BETWEEN MOBILE STATION AND INFORMATION CENTER IN NAVIGATION SYSTEM}
[7] The present invention relates to a navigation system, and more particularly, to a method for transmitting and receiving between a mobile terminal and an information center.
[8] In general, a navigation system displays a current position of a moving object calculated by using information received from a global positioning system (GPS) on a map displayed on a display screen. In addition, the navigation system displays various information necessary for driving such as displaying the moving direction of the moving object, the distance to the destination to be traveled, the current moving speed of the moving object, the path set before the driver, the optimum path to the destination, and the like. To provide. Such a navigation system (or GPS positioning device) is currently mounted on various kinds of moving objects such as ships, aircrafts, automobiles, etc., and is widely used to check the current position and moving speed of moving objects or determine a moving path.
[9] Recently, a navigation system for providing a navigation function through a mobile terminal has been developed, and FIG. 1 shows a schematic configuration of such a navigation system.
[10] Referring to FIG. 1, the navigation system includes an information center 100, a wireless network 200, a mobile terminal 300, and an intelligent transportation systems (ITS) terminal 400. The information center 100 stores map data and real-time traffic information. When a navigation function is requested from the mobile terminal 300, the information center 100 generates a corresponding navigation information by referring to the map data and real-time traffic information and moves through the wireless network 200. Provided to the terminal 300. The wireless network 200 is a path for information transmission between the information center 100 and the mobile terminal 300. The mobile terminal 300 typically operates as a mode for providing a voice call service to a user, as well as a navigation mode for supporting a navigation function. The mobile terminal 300 is connected to the wireless network 200 in the navigation mode, receives various navigation information provided from the information center 100, and provides the user with navigation information received in association with the ITS terminal 400.
[11] In the navigation mode, the user may set the current location and the destination of the vehicle on the mobile terminal 300 and request the optimal driving route guidance to the information center 100. According to the setting, the user may optimize the current location and the destination, which are typical navigation functions from the information center 100. You can be guided by the driving route. In the navigation mode, the user can also access the information center 100 through the mobile terminal 300 to access surrounding facilities (e.g. gas station, rest area, maintenance center, bank, hospital / pharmacy, lodging, tourist attraction, restaurant / café, theater / performance hall, etc.). ).
[12] As described above, the navigation system is mounted as a separate device in a moving body such as a vehicle to provide a convenient function such as route guidance to the driver. To this end, the mobile terminal 300 should access the information center 100 through a wireless network, set a destination desired by the user, and download the route guidance data generated in the information center using the wireless network.
[13] However, due to the limitation of data communication using a wireless network, a connection may be disconnected in the middle of setting a destination or receiving route guidance data. For example, the mobile terminal 300 may lose the connection between the mobile terminal 300 and the information center 100 due to a problem in the wireless network through a tunnel while setting a destination or receiving route guidance data. In such a case, the mobile terminal 300 had to download destination setting and route guidance data from the beginning again.
[14] As described above, when the connection between the mobile terminal 300 and the information center 100 is disconnected during destination setting or in the middle of receiving route data, there is a need to download destination setting and route guidance data again. In addition, there is a problem that the burden on the communication cost of the user is greatly increased by receiving the same data again. In addition, during this reconnection, the car enters a different route and the current position is different. Therefore, there is a problem that other route guidance data from the changed current position to the destination must be downloaded again from the beginning.
[15] Accordingly, an object of the present invention is to provide a method for transmitting and receiving data between a mobile terminal and an information center in a navigation system.
[16] Another object of the present invention is to provide a method for automatically reconnecting data when a mobile terminal is disconnected from an information center while setting a destination or receiving route guidance data in a navigation system.

It is characterized by consisting of seven processes.
[18] According to an aspect of the present invention, there is provided a method for transmitting and receiving route guidance data of a mobile terminal in a navigation system including an information center for providing navigation information and a mobile terminal connected to the information center through a wireless network. A first step of storing information on the data received up to that time when the connection is lost while receiving route guidance data; a second step of transmitting a reconnection request message and a message corresponding to the size of the received data to the information center; When the remaining path guidance data is transmitted from the information center is characterized in that the third step of receiving it.
[19] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.
[20] 2 is a view showing the configuration of a mobile communication terminal to which the present invention can be applied.
[21] Referring to FIG. 2, the mobile communication terminal 300 includes an antenna (ANT), a controller 200, a transceiver 210, a memory 220, a key input 230, a display 240, a voice processor 250, a microphone (MIC) and a speaker (SPK). : Speaker). The antenna ANT transmits a transmission signal from the transceiver 210 to the information center 100 through a wireless network, and receives a signal from the information center 100 through a wireless network. The controller 200 performs overall operations of the mobile communication terminal. In particular, according to the present invention, when the connection with the information center 100 is lost while transmitting and receiving the navigation data, the controller 200 automatically controls the operations of subsequent data operation. Here, the navigation data is data transmitted and received between the mobile terminal 300 and the information center 100 in a navigation system such as data required for setting a destination and route guidance data.
[22] The transceiver 210 outputs a signal to be transmitted to the information center 100 and receives a signal from the information center 100 through the antenna ANT. The memory 220 stores a navigation program for performing an operation according to an embodiment of the present invention and data processed according to the operation. Particularly, in the present invention, when selecting a destination setting item, the memory 220 stores upper destination related information until the information center receives information about lower items.
[23] The key input unit 230 is for an interface between the mobile communication terminal 300 and the user. The user may set a navigation mode through the key input unit 230 and request various navigation information according to a navigation service. The display unit 240 displays a screen for displaying during operation processing according to an exemplary embodiment of the present invention. For example, the screen for display during the processing may refer to the drawings shown in FIGS. 6A to 6E below.
[24] The voice processor 250 processes a voice signal input through the microphone MIC, and also processes a voice signal to be output to the speaker SPK. The microphone MIC inputs a voice from the user, converts the input voice into an electrical signal, and outputs the converted voice. The speaker SPK converts an electrical signal to be output to the user into voice. As described above, it should be noted that the operation according to the embodiment of the present invention is assumed to be performed in the mobile communication terminal 300.
[25] 3 is a flowchart illustrating a process of transmitting and receiving data between a mobile terminal and an information center according to an exemplary embodiment of the present invention.
[26] 4 is a signal flowchart between a mobile terminal and an information center when setting a destination according to an embodiment of the present invention, and FIG. 5 is a signal flowchart between a mobile terminal and an information center when receiving route guidance data according to an embodiment of the present invention.
[27] In the present invention, when data for requesting destination setting is input through the user interface, the mobile terminal 300 transmits a message requesting a destination setting item to the information center. In addition, when a destination is selected from the information center and a destination is selected for the destination setting item, the destination setting data is transmitted to the information center 100 and the destination setting data is stored in the memory 220. In addition, after setting the final destination, information is transmitted to the information center 100 to receive route guidance data from the information center 100. At this time, if the connection is disconnected during destination setting or receiving route guidance data, a message requesting reconnection to the information center 100 is transmitted.
[28] In addition, when the information center 100 receives a message requesting the destination setting from the mobile terminal 300, the information center 100 transmits a lower item of the destination setting data to the mobile terminal 300, and finally generates the path guidance data necessary for the guidance of the requested destination. Send to the terminal 300. In addition, when the connection is disconnected during the path guidance data transmission, if a reconnection request message is received from the mobile terminal 300, the communication is resumed and transmitted again from the item requested by the mobile terminal 300. Therefore, even if the connection is lost, it is not necessary to receive the item for setting the destination or the route guidance data for the last requested destination from the beginning.
[29] First, referring to FIGS. 3 and 4, a process of reconnecting when a connection is lost during destination setting will be described. The controller 200 checks whether there is a destination setting request, and if there is a destination setting request, transmits a destination setting request message to the information center 100 in step 500. In operation 502, the information center 100 transmits a lower item for the destination setting request to the mobile terminal 300. Here, the lower item means a destination setting item which selects a destination setting and sets the next step.
[30] In general, the way to set the destination is to narrow down from a large area to a narrow area. For example, the “Gyeonggi-do” of the widest area is included in order to visit “Maetan-dong Samsung Electronics, Paldal-gu, Suwon-si, Gyeonggi-do”. From the sub-item, which is the destination setting item, the destination of the narrow area to which "Samsung Electronics" belongs is set. Therefore, five destinations must be set in order to set the final destination.
[31] For example, as shown in FIG. 6A, it refers to the widest area including a destination such as Gyeonggi-do, Seoul, and Gyeongsangnam-do. The control unit 200 of the mobile terminal 300 that receives this displays the received lower item on the display unit 240 as shown in FIG. 6A. In operation 40, when a user selects a destination from among lower items displayed through the user interface, the controller 200 stores the selected destination setting information in the internal memory. Hereinafter, the destination setting information is destination setting data. That is, destination setting data is data corresponding to a destination selected through the user interface for the destination setting item.
[32] In operation 502, the mobile terminal 300 receives a selection of a destination through a user interface, and transmits destination setting information to the information center 100 in step 504.
[33] In step 41, it is checked whether the destination sub-item has been received, and if the sub-item has been received as a result of the test, the controller 200 displays the destination sub-item as shown in FIG. 6A and proceeds to step 44. In step 44, the control unit 200 checks whether the destination sub-item received in step 500 is an item for setting the final destination, and if it is not the final destination setting item, the controller 200 proceeds to step 40 to continue the destination setting process.
[34] On the other hand, if it is determined in step 41 that the destination sub-item has not been received and the sub-item is not received, the process proceeds to step 42 and determines that the connection is disconnected as in step 506, so that the control unit 200 performs reconnection with the most recent destination setting information stored. Send the requested message to information center 100. This is the same as step 508 of FIG.
[35] In step 510, the information center 100 that has received the reconnection request and the last destination setting information transmits a lower item, which is a destination setting item, required in the next step of receiving the last destination setting to the mobile terminal 300. On the other hand, in the process of setting the destination in order to visit "Maetan-dong Samsung, Paldal-gu, Suwon-si, Gyeonggi-do," we selected "Gyeonggi-do" and sent it to the information center 100. In this case, the mobile terminal 300 stores "Gyeonggi-do," which is the last destination set data, until the connection is disconnected in step 504. Then, the mobile terminal 300 transmits a reconnection request message to the information center 100 as shown in step 508. It transmits data about "Gyeonggi-do" which is the most recent destination. In step 510, the information center 100 receives the next item for the lower item so that the user can set a destination such as Suwon city, Seongnam city, etc., as shown in FIG. 6B.
[36] Next, referring to FIGS. 3 and 5, a process of reconnecting when a connection is disconnected while receiving route guidance data of a destination set by setting a destination will be described.
[37] In step 43, the control unit 200 displays the received destination setting item, proceeds to step 44 and checks whether the received destination setting item is the final destination setting item, and proceeds to step 45 if it is the final destination setting item. Proceed to perform the destination setting process.
[38] In operation 45, the controller 200 transmits the final destination information and the current location data to the information center 100. This is the same as step 600 of FIG. The information center 100 which receives this transmits route guidance data to the mobile terminal 300. As such, the controller 200 displays the path guidance data while the requested data is received as shown in FIG. 6C.
[39] The controller 200 downloads the transmitted data in step 46. In step 47, the controller 200 checks whether reception of the route guidance data is completed. If reception of the test result is completed, the process proceeds to step 48 and the control unit 200 guides the path through the display or by voice. On the other hand, if the reception is not completed, the process proceeds to step 49 and the controller 200 checks whether the connection is disconnected. The disconnection of the connection detects that the connection is disconnected when data is not continuously received for a predetermined time. If the connection is not disconnected, the process proceeds to step 47 to check whether the reception is completed. If the connection is disconnected in step 604 while receiving the path guidance data, the process proceeds to step 50 to store the received data information. This is the same as step 606 of FIG. 5. By doing this, you can save that the information previously received is not perfect. In operation 51, the controller 200 transmits a message requesting reconnection to the information center 100 and information on the received data stored in operation 50 to the information center 100. At this time, while requesting the reconnection, the controller 200 of the mobile terminal 300 displays a screen indicating that the connection is being reconnected as shown in FIG. 6D. This is the same as step 608 of FIG. 5, and the information center 100 that receives the data subsequently transmits route guidance data after data previously received in step 610. The mobile terminal 300 receives and receives the remaining route guidance data. When the reception is completed, the mobile terminal 300 displays the route guidance message as shown in FIG. 6E or starts the route guidance by voice.
[40] In the foregoing detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.
[41] As described above, the present invention automatically connects the mobile terminal to the information center in the middle of destination setting or receiving route guidance data so that the data can be continuously operated to receive the destination setting and route data for the first time. There is an advantage that does not need to be performed from. In addition, by being able to work as described above, there is an advantage of reducing unnecessary wireless data communication charges.
