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

First, referring to FIG. 8.

FIG. 8 is a block diagram illustrating a system environment in which a navigation method of the present invention is performed. The personal navigation method of the present invention includes a personal portable terminal 1 (hereinafter referred to as a 'terminal') and a hotspot server 2 (hereinafter referred to as a 'terminal'). The server is performed through the hotspot wireless network 2).

Referring to FIG. 8, the terminal 1 entering the hot spot requests the terminal registration to the hot spot server 103 through the hot spot wireless network 2, and the hot spot server 3 that has approved the terminal registration receives the hot spot wireless network ( Provides event information requested by the terminal 1 through 2).

Device configurations of the terminal 1 and the hot spot server 3 of the present invention will be described in detail with reference to FIG. 9.

1 is a flowchart illustrating a personal navigation method according to an embodiment of the present invention.

First, the terminal enters a hot spot (S100). The terminal may be a mobile phone, a personal digital assistant (PDA), a notebook computer equipped with a wireless LAN access device, or the like.

After step S100, the terminal continuously determines whether an information collection event has occurred (S102). For example, when the user inputs destination information into the terminal, it may be determined that an information collection event has occurred. Alternatively, the event may be selected according to the service menu provided through the hotspot wireless network at the hotspot in step S100.

If it is determined that the information collection event has occurred, the terminal determines whether the destination route search event (S104).

If it is determined that the generated event is a destination path search event, the terminal requests destination path search information from the server, and receives the destination path search information from the server to navigate (S106).

If it is determined that the generated event is not the destination route search event, the terminal receives information on a hot spot provided by the server according to the generated event (S108). In the case where the hot spot is, for example, Yonsei University, if the generated event is a building guide event, the server may provide a building detail guide service existing near a path through which the terminal moves. If the hot spot is, for example, Yonsei University, if the generated event is an event guide event, the server may provide a detailed guide service such as an event or a meeting held near a path through which the terminal moves. If the hot spot is, for example, a tourist destination, if the generated event is a tourist guide event, the server may provide a detailed guide service of the tourist spot that exists near the path to which the terminal moves.

FIG. 2 is a flowchart for explaining a preferred embodiment of the step S100 shown in FIG.

First, the terminal continuously determines whether it has entered a hot spot (S200).

In step S200, whether the terminal enters the hot spot may be determined according to, for example, the strength of a signal received from the hot spot wireless network. In addition, whether or not the terminal enters the hot spot may be determined by acquiring the current location information of the terminal and comparing the obtained current location information with coordinate information on the range of the hot spot previously stored in the terminal.

If it is determined that the terminal has entered the hot spot, the terminal requests the terminal to register the terminal (S202). At this time, the terminal first measures the current location, and transmits the current location information to the server to request registration. The registration request may be performed by transmitting information in the form of identification number (ID), mobile phone number, and the like.

The server receiving the request registers the terminal (S204). At this time, the server may notify the terminal that the terminal is registered.

3 is an exemplary embodiment further comprising the step (S206) of terminating the mobile terminal data communication with the outside of the hot spot after the step S204 of FIG. At this time, the terminal may terminate the mobile terminal data communication with the outside of the hot spot after being notified from the server that the terminal is registered. The step S206 may be further provided when the terminal is a device capable of data communication through an external wireless network such as a mobile phone or a telematics terminal. In step S206, for example, assuming that a mobile phone or a telematics terminal is provided with a navigation service for visiting Yonsei University through an external wireless network, after the terminal enters Yonsei University, which is a hot spot, the mobile terminal performs data communication with the outside of the hot spot. It is a step provided to terminate and to provide a navigation service in the hot spot.

4 is a flowchart for explaining another preferred embodiment of the step S100 shown in FIG. First, the terminal continuously determines whether it has entered a hot spot (S200). If it is determined that the terminal enters the hot spot, the terminal terminates mobile terminal data communication with the outside of the hot spot (S206). This is an embodiment where the terminal is provided from the hotspot server regardless of whether the terminal enters the hotspot itself.

FIG. 5 is a flowchart for explaining a preferred embodiment of step S106 shown in FIG.

The terminal measures the current position (S300).

The terminal inputs destination information (S302).

The terminal transmits the current location information and the destination information to the server (S304).

The server searches for a path connecting the current location and the destination (S306), and transmits the searched destination path information to the terminal (S308).

The terminal stores the route search information and performs personal navigation by using the same (S310). Personal navigation may be provided to the user as a voice information or map information service.

Measuring the current position (S300) may be performed after the next step S302. If the current position measurement is performed at the time of terminal registration in step S100 of FIG. 2, step S300 may not be performed. The measurement of the current position may be performed by a global positioning system (GPS) method, a differential global positioning system (DGPS) method, or the like.

If it is determined in step S102 of FIG. 1 whether information collection event has occurred, if it is determined that destination information is input, step S302 may not be performed. Here, the destination information may be input as various methods such as an identification number of a building or a search word related to the destination. The identification number of the building may be a building name such as building number, library, engineering building, etc., if the hot spot is Yonsei University. Also, a search term related to a destination may be the content of data stored in a database of a hotspot server, such as a seminar title, an opened course name, and a professor's name.

6 is a flowchart for explaining a preferred embodiment of the step S310 shown in FIG.

The terminal performs navigation by the route search information provided from the server (S400).

The terminal continuously or periodically determines whether a new event request of the user has occurred while performing navigation (S402). This may be performed by interrupt processing when an event request is generated by a user's operation or by detecting whether an event request is periodically generated.

If a new event occurs, the terminal requests the event generated in the server, and accordingly receives the information on the hot spot provided by the server to inform the user (S406).

If it is determined in step S402 that a new event does not occur, it is determined whether the destination has been reached (S404). If the destination has not been reached, the process proceeds to step S400 to continue navigation and when the destination is reached. Step S310 ends.

FIG. 7 is an embodiment in which step S110 is added after step S106 or step S108 of FIG. 1. In step S110, it is determined whether the terminal has left the hot spot.

Whether or not the hot spot is separated may be determined according to the strength of the signal received from the hot spot wireless network to the terminal, similarly to determining whether to enter the hot spot. In addition, whether the terminal has left the hot spot may be determined by acquiring the current position information of the terminal and comparing the obtained current position information with coordinate information about the range of the hot spot previously stored in the terminal.

Determination of whether or not to leave the hot spot may be performed even after the desired event is completed as shown in FIG. 7, but may be periodically performed even if a service according to the event is in progress.

After step S106 or step S108, the terminal determines whether it has left the hot spot, and if it is determined that the hot spot has not left, proceeds to step S102, and if it is determined that the hot spot has left the embodiment of the navigation method (S110).

In addition, step S110 may be implemented to terminate the present navigation method after connecting the mobile terminal data communication with the outside, if it is determined that the terminal has left the hot spot.

7 is an embodiment of determining whether the hot spot is left after the event is finished, the determination of whether the hot spot is left may be performed periodically after entering the hot spot in step S100. In this case, when the terminal leaves the hot spot regardless of the end of the event, the navigation method ends.

The event processing request unit 108 converts the event 105 generated according to the control signal 101 into a modulated request signal REQ1 for transmission. The request signal REQ1 is transmitted to the hotspot server through a hotspot wireless network (not shown). The event processing request unit 108 may request to process an event generated by a user input through the user's manipulation unit 106, but may be triggered by the determination information 101 that the hot spot has been entered and request event processing. In this case, the event processing request REQ1 may be, for example, a request for providing information about a list of services provided by the hotspot server or the contents thereof. In this case, the user who referred to the information provided from the server may be implemented to operate the operation unit 106 again to select an event.
