Description

The mobile communication terminal which supports the function of simple navigation system and the control method.

The present invention overcomes the disadvantages and constraints of the existing navigation apparatuses and methods, which are variously performed, and a mobile communication terminal supporting a simple navigation function to implement an effective navigation function at a minimum cost, and a control method thereof. It is about.

In the conventional navigation system, map information is stored in a storage device such as a CD-ROM, and when a destination address is known, the current navigation system shows a current location and a destination location and displays a route. However, to implement such a function, expensive equipment was needed, and if the address was not known and the information on the map was not accurate, the user could not be effectively guided. In addition, most users go to the destination only by phone number and approximate location information rather than an accurate address or an accurate map.

Further, in the method for setting a destination, even when using a phone number, the existing technology retrieves address information with a phone number, sets a destination using the confirmed address information, and maps relevant map information from the map information storage device. Read and display the optimal route from the current location to the destination on the map because there was a disadvantage inexpensive and easy to use as in the present invention.

In addition, the mobile phone supports the function of identifying the location of the mobile phone user by referring to the location of the base station communicating with the mobile phone. Even when using this function, the surrounding directions must be displayed on a relatively small mobile phone screen. It is difficult to support satisfactory navigation because it has limitations and disadvantages such as communication cost for downloading map (map) data from server.

In addition, in the case of the existing simple navigation terminal which displays only the relative distance and direction between the current location and the destination without using map information by using a separate terminal rather than a mobile phone, GPS location information, that is, longitude and latitude data, is used to set the destination. It has disadvantages such as inconvenience in setting.

In the present invention, the destination can be set only with the phone number, not the address or GPS location information of the destination, and displays only essential basic information such as the distance to the destination and the direction to proceed using the current location and orientation of the mobile phone user. Unlike existing technologies, it does not rely on geodatabases such as CD-ROMs, omits the process of converting addresses to GPS location information, and also requires expensive display devices to display complex map information. The main technical challenge is to implement a simple navigation function through a mobile phone.

In addition, not only fixed destinations such as buildings, but also the location of non-fixed destinations such as mobile phone users, and the ability to easily contact the desired destinations through this, users do not rely on complex map information It is an object of the present invention to provide a method of guiding a person to safely reach a destination without fail.

The present invention provides a simple navigation method for allowing a user of a mobile communication terminal such as a mobile phone to reach a destination simply and safely using his mobile communication terminal, and a terminal for supporting the same. The present invention will be described in the form of adding a description of a simple navigation method based on this configuration while developing a description of the operation.

Hereinafter, the contents of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram according to a first embodiment of the present invention, which is the simplest configuration method using a mobile phone as shown in the drawing. The system level of action is as follows.

That is, a mobile communication terminal 2 user who can be represented by a mobile phone selects a destination to which he / she wants to go through his or her mobile phone, a phone number of another mobile phone user, and the terminal user via wireless communication selects the selected phone number. When transmitting to the subscribed mobile service provider server 1, the mobile service provider server may be connected to the mobile communication terminal from its own database managed by itself or from a database located at a server of a third information provider connected to the service provider's server. 2) GPS user's location information about the phone number selected by the user, that is, longitude and latitude information is automatically searched and the search results are sent back to the mobile communication terminal 2 so that the terminal user can find the GPS of the target he or she wants to go to. You can get location information.

GPS location information is generally difficult to obtain even through atlases, which are printed and distributed. Through the above method, a user of a mobile communication terminal can easily obtain GPS location information about his or her destination. Can be stored and stored in

In this case, the telephone number includes not only a normal landline telephone number but also a telephone number of a mobile communication terminal. The information can be set, so if the location is moved, the corresponding GPS location information needs to be updated.

In addition, in the case of a mobile communication phone that is not wired, its location is not fixed and changes frequently, so the mobile service provider continuously monitors the current location of the subscriber of the phone number and stores its GPS location information management database. It is necessary to continuously update the GPS location information of the terminal.

However, unlike in the case of a landline phone, in the case of a mobile communication terminal, a very frequent update operation is required to provide up-to-date GPS location information, which is not practical in view of the number of subscribers secured by ordinary mobile communication operators. This can be In addition, it may not be a great thing for a user of a mobile communication terminal to be exposed, and there is no possibility of invading an individual's privacy. For this reason, in a database that stores GPS location information, for each phone number, choose whether or not to disclose the GPS location information to a third party other than the subscriber itself. It also needs to be stored and managed together.

Of course, technically, it is not practical to prevent it from being disclosed to the database manager, but at least it can be controlled to be disclosed to a third party including an unspecified number of persons, not directly managing the database. will be. For this purpose, it may be said that the present invention is provided with a separate flag that can set whether or not to be disclosed.

In addition, in particular, the mobile communication terminal has a flag for determining whether to continuously update the GPS location information or to leave it without updating, so that the loss and burden of unnecessary updates can be eliminated. It will be a suitable embodiment.

Of course, such flags could be set by the database administrator, but would be more useful in many ways if the subscriber could change the settings from time to time, and the burden on the administrator would be greatly reduced. Therefore, it will be a very useful embodiment for the mobile communication terminal to support a setting menu for allowing a user to change a setting for managing his or her own GPS information through the mobile communication terminal.

In this case, the flags may need to be set by the corresponding database manager, not the subscriber itself, in the information management level. At this time, if necessary, the subscriber and the manager may manage dually, and the embodiment may be a more useful method such as releasing information when both settings match.

In addition, in the case of a database storing GPS location information, it is possible to be located in a server of a mobile communication service provider or a server of a third information provider according to the component thereof. It will be possible. That is, it may be more efficient that information about the landline telephone is distributed and stored in the server of the landline telephone operator and in the case of a mobile communication telephone.

Of course, these servers must be connected to a server of a mobile communication provider subscribed to by a mobile terminal user requesting GPS location information through a dedicated line or an internet network.

In the case of the database, one GPS location information may be input for several telephone numbers. This many-to-one situation can occur when multiple phones exist in the same room, such as an office.

In addition, since the position of the mobile communication terminal changes from time to time when the mobile communication terminal holder wants to visit, it is a fact that it is a considerable burden to continuously update and manage it on the database. Therefore, in some cases, it may be an effective embodiment to exclude a database and to exchange GPS positions with each other through data transmission and reception between mobile communication terminals.

That is, if someone wants to know the location of a particular person and requests the GPS location of the terminal while designating the specific person's phone number through his terminal, the mobile service provider responds to the request of the terminal possessed by the specific person. It is possible to determine the location and send it to the terminal of the person who requested it, or to send someone's own GPS location information to another person, for example, the GPS of his terminal for the person B who is looking for him. If the user wants to deliver the location information, his or her GPS location information can be transmitted to the B terminal using a short message service. Of course, it is not necessary to use a short message service, but merely a means for transmitting data corresponding to GPS location information.

Now, a more detailed navigation method and configuration will be described with reference to FIG. 2.

As mentioned above, an input means 11 for inputting a destination or searcher's mobile phone number using a mobile communication terminal, a wireless communication unit 10 which a normal mobile communication terminal basically has, and mobile communication A memory device 13 for storing GPS location information received from a database stored in a server of an operator, an electronic compass module 14 for identifying a direction in which a mobile communication terminal holder is facing, and a mobile terminal user's current A GPS receiving module 15 for determining a position, a display unit 16 for displaying a relative position of the destination and a direction of the destination as viewed by the user based on the current position and the current position of the user of the mobile communication terminal, and How you can deliver sound information, such as voice alerts or alarms, that are particularly useful when you are driving. Through a mobile communication terminal composed of a speaker 17 to be desired, and a control unit 12 for controlling the components and for calculating relative distances and directions with GPS information of the current location and the destination location. It is possible to support a simple navigation method that can lead a user to a destination without using map information.

Of course, some of these physical components may also be implemented through expansion devices (modules) designed in a separate mobile communication terminal (optional) device concept designed to be connected to a general mobile communication terminal rather than embedded directly in the mobile communication terminal itself. It can be.

Hereinafter, the components of FIG. 2 and the navigation method associated with the components will be described in more detail.

First, in the case of the input means 11, the keypad may be the first input means. However, some mobile communication terminals and the like already have a voice recognition function, so that the phone number can be set by decrypting the voice information input through the microphone. And if you use the keypad or voice recognition module, you can directly enter the phone number itself, but it is very important to set the phone number by selecting a destination or destination phone number from a pre-stored phone book or recent call log. This can be a useful method.

In addition, in the case of using speech recognition, it is preferable to include a procedure for displaying the recognized contents and allowing the user to confirm the errors in order to prevent errors due to recognition errors.

Furthermore, a user may use a data port (also referred to as a serial data port, etc.) that mobile communication terminals typically have a telephone number designated by a separate terminal device such as a PDA connected to the mobile communication terminal. It is also preferable to perform a database search operation through the data received from the port).

In addition, another embodiment of the present invention accesses a desired website using a wireless Internet function supported by recent mobile communication terminals and selects a destination or a destination existing on the website, and through the selection, selects the web. It is also a very useful embodiment to obtain the phone number information that is not known in advance by automatically downloading the destination or target phone number from the site.

Once the phone number of the destination is set as described above, a database search operation using the same is to be performed through the wireless communication unit 10. In this case, the user may set the phone number through various input methods described above, and then perform an automatic search operation on the database by pressing a navigation button separately allocated on the mobile communication terminal.

Of course, in some cases, it is also possible to enter a phone number with the simple navigation function selected first. In this case, as shown in FIG. 8, the server or the wireless Internet site is accessed through a key combination of the mobile communication terminal. For example, the automatic search operation may be performed by designating a destination telephone number and giving the destination telephone number.

As described above, when a phone number is designated, a database search operation for the designated phone number is started, and the GPS location information corresponding to the phone number is transmitted to the requesting mobile communication terminal, the control unit 12 receives the destination. GPS location information is stored in the memory device 13.

Since it does not make sense to continuously download GPS location information unless the destination or destination changes, the downloaded destination GPS location information is saved.

As mentioned above, once the GPS location information of the destination is downloaded, the distance from the current location to the destination and the current GPS location information obtained through the GPS receiving module 15 and the GPS location information of the destination are determined. The direction to reach can be obtained through the calculation in the control unit 12.

However, if the user possessing the mobile communication terminal cannot know the direction in which the user is heading, it is impossible to properly indicate the direction of the destination. Therefore, it is required to determine which direction the terminal holder is facing in the north, south, east, west, and north, and the orientation information can be obtained from the electronic compass module 14 including a geomagnetic sensor.

As shown in FIG. 4, the directions E, W, S, N (30), that is, the direction toward the north, south, west, and north, and at the same time, the destination position display 32 are also changed to correspond to the change of the orientation information.

For example, in the case of FIG. 4, when the user rotates the body slightly to the right and the N 30 moves to the left by 30 degrees than shown in the figure, the destination position display 32 also moves to the left by 30 degrees. As a result, the angle of the destination is changed from 45 degrees to 15 degrees with respect to the user's facing front.

Of course, it is possible to display the navigation information without having the electronic compass 14 or the like, but it is very difficult to point the direction of the destination properly in a situation in which the terminal user changes the direction to be in place without moving. It can be seen that having an electronic compass can provide more convenience. However, the additional costs that follow are inevitable.

However, such distance and direction calculation may be performed not only on the microprocessor in the terminal but also on the base station or the server of the mobile communication provider to which the mobile communication terminal is connected. In this case, the calculated result is transmitted to the mobile communication terminal through the wireless communication unit 10. In some cases, it may be made through a processor embedded in the simple navigation device connected to the mobile communication terminal. Of course, when processed by a separate simple navigation device, it can be said that the indicators of the distance and direction information are also made through the display device on the simple navigation device.

In addition, the GPS receiving module 15 and the electronic compass module 14 may also be operated by being connected to the mobile communication terminal in a separate external module form connected to the terminal instead of being embedded in the mobile communication terminal itself. The reason is that these two components are not embedded in the existing mobile communication terminal, so it is impossible to support the simple navigation method provided by the present invention. Of course, recently released mobile phones are supported by the location tracking function to determine their location by using a base station without using GPS satellites, but these functions are mainly used as a means of identifying their location and used as an effective navigation means. It's not happening.

Once the distance and direction to the destination is calculated, it can be displayed in various forms as shown in FIGS. 4 to 6. First, the present position display 31 is located at the center of the screen, and the destination position display 32 is located at the periphery thereof. Alternatively, the destination position display 32 may be placed at the center of the screen. In addition, as shown in Figure 6 may be displayed through the destination location indicator arrow 34, in this case, the length of the arrow can be changed together according to the distance to the destination so that the distance can be easily estimated, or the length of the arrow is fixed The distance indication information may be used to obtain information about the distance to the destination.

Furthermore, as shown in FIG. 5, a method of recording a route traveled by a user in a predetermined area and displaying the same through a continuous line may provide a method of easily finding a destination. Of course, the stored route data may be stored separately, and may provide data for future reference when the user leaves the destination and moves to another location.

6, 7 or 8, it is also a useful embodiment to display the time and the distance direction numerically in addition to the graphic information.

In addition, it is a very useful embodiment for a driving user to deliver voice and alarm information to a user through the speaker 17 separately from the display methods performed through the display unit 16. The speaker 17 may be replaced by a buzzer or an earphone in some cases. Like the display unit 16, the speaker 17 is not embedded in the mobile communication terminal itself, but is connected to a terminal. The LCD may be replaced by a built-in navigation device or a speaker or a buzzer. In this case, there is an advantage of overcoming limitations such as screen size of a mobile communication terminal such as a mobile phone.

When providing information through the LCD screen of the terminal is meaningless while driving, it may be sufficient to provide distance and direction information to the destination through voice information using the hands-free function. At this point, for example, the destination is 300 meters ahead at 2 o'clock. This can be supported by various alarm sounds along with voice information such as

In addition, when the information is to be delivered through a voice or an alarm, there are the following embodiments.

First, when a destination is located within a certain distance according to a terminal manufacturing step or a user's setting, the alarm may be notified through an alarm or the like, and the user may be notified that the user is passing the destination by notifying the user when the user is away from the destination. .

In general, in view of the intersection of roads at right angles, if there is an intersection near the point where the destination direction is 90 degrees or 270 degrees, the right direction or the left direction is a very effective movement method, and thus the direction of the destination is 90 degrees. Alternatively, an alarm for recognizing when 270 or near is a very useful embodiment.

In addition, the mobile communication terminal supporting the simple navigation method described above has a setting menu for setting the various flags supported on the database, that is, the GPS location information disclosure flag. In particular, regardless of the flag setting on the database, the terminal may disable the terminal's own location calculation function, or may refuse to transfer its location information to the server of the mobile operator through the base station. It is also desirable to have a function to protect the privacy of individuals by applying.

For reference, FIG. 7 briefly summarizes the above-described simple navigation method in a flow chart form, and description thereof will be omitted by overlapping with the previous detailed description. As shown in FIG. 7, the current location is set in the simplified navigation function. It can be seen that the steps from the information checking step to the screen display step are continued at regular time intervals.

Of course, when the GPS location information of the destination is changed, it is necessary to download the changed destination GPS location information again.

Figure 3 is a simple schematic representation that the GPS receiver module and the electronic compass module are separately provided outside the mobile communication terminal and are connected through the data port of the mobile communication terminal. In this way, it is possible to configure a mobile communication terminal (apparatus) supporting the simple navigation function of the present invention by using a GPS receiving module and an electronic compass supported in the form of an option module of the mobile communication terminal.

As described above, the user of the mobile communication terminal has a simple and inexpensive navigation function that enables the user to easily navigate to the destination using only the phone number of the destination using his mobile communication terminal that supports the simple navigation method. It offers the advantage of being supported without having.

That is, even without the correct address, the GPS location information of the destination can be known using the wireless access function of the mobile phone and the destination's phone number, so there is no need for a separate CD-ROM device and no software for providing a map. .

Such a simple navigation method can provide a very effective guide function for a walking mobile terminal user by moving away from the conventional vehicle driver-centered navigation concept, and can be fixed like a third mobile terminal holder as well as a fixed destination or target. It provides a method of targeting an untargeted target and a useful means of finding the target target.

In addition, the simple navigation method supported by the mobile communication terminal and the database of the present invention is more effective in the situation where the map information is not properly input or the map information cannot be obtained because it does not depend on the map information. can do.

For users on the move, such as driving a car, they can get to their destination through simple voice and video information rather than relying on complex map information that requires a lot of attention. This is another advantage of not using map information because it provides a safe navigation.
