 1 is a diagram schematically illustrating a system for providing a weakness data using a portable terminal according to a first embodiment of the present invention.

Referring to FIG. 1, a system for providing route data using a portable terminal according to an exemplary embodiment of the present invention includes a first portable terminal 100 and a route data from the first portable terminal 100 for generating route data including a movement route. And a mobile communication network 300 for transmitting and receiving data between the second portable terminal 200 and the first and second portable terminals 200.

The first portable terminal 100 may be equipped with a predetermined positioning program for measuring its position in order to perform a function according to the present invention. Preferably, the positioning program may be mounted in a flash memory embedded in the first portable terminal 100. In the positioning program, a scheduling algorithm that wakes up at regular intervals and searches for a location service request signal is coded.

The first portable terminal 100 according to the present invention can position its own position in various ways. For example, a technique for positioning a terminal using wireless communication includes a handset-based method using GPS, a network-based method using a base station reception signal, and a combination of these two methods. There is a hybrid method to improve the accuracy of the.

Handset-based method using GPS receives GPS signals from GPS satellites using GPS module (including GPS antenna and GPS receiver) installed in the terminal, extracts navigation data included in GPS signals, and uses built-in GPS positioning program. It can be used to position its position from the GPS signal. This positioning method may be implemented through a GPS positioning program by mounting the GPS module to all terminals wirelessly connecting the GPS module to the mobile communication network.

In the network-based method without using GPS, the location of the terminal can be generally determined using communication data between the base station and the terminal. Positioning method of mobile communication terminal using TA (Timing Advance) technology in mobile communication network that does not use GPS, for example, Global System for Mobile communication (GSM) network, Time Difference of Arrival in Wideband Code Division Multiple Access (WCDMA) network ) Positioning methods.

In the positioning method using the TA technology in the GSM network, a TA parameter is transmitted from a base station to a terminal to compensate for a delay of data transmitted and received between the base station and the terminal, and the base station and the terminal are synchronized. Such a TA technique uses timeslot advance information, and TA is applied to corresponding base stations even when handovered to another cell. At this time, if the user handovers the terminal twice twice, three time advances can be known, and the position of the terminal can be located from the three time advances using triangulation.

The TDOA positioning method locates a terminal using time information on three or more base stations without using GPS. The distance between the first base station and the terminal is calculated using the difference between the time T1 at which the first base station transmits a signal to the terminal and the time T1 'responded by the terminal. In this case, the distance is calculated as 'speed / time' and the speed uses the speed of electromagnetic waves. In the same manner, the distance between the second base station and the third base station and the terminal is also calculated. As described above, two hyperbolas are obtained from the positions of the first to third base stations using the three calculated distance values, and the position of the corresponding terminal may be determined by finding an intersection point of the two hyperbolas.

In addition to the above-described positioning method, various positioning methods may exist, and the first portable terminal 100 according to the present invention may know its position in such various positioning methods. Since the positioning methods of the various first portable terminals 100 are well known technologies, detailed descriptions thereof will be omitted.

As described above, the first portable terminal 100 according to the present invention can measure its position in various ways, but preferably includes a GPS module to receive satellite signals from GPS satellites, and The positional coordinates of the first portable terminal 100 are periodically measured from the satellite signal using a positioning program stored in the terminal. The first mobile terminal 100 displays its movement path on the map image by displaying the position coordinates periodically measured on the map image previously stored therein. The first mobile terminal 100 may position its position regardless of whether the first mobile terminal 100 is connected to a mobile communication network such as a synchronous scheme such as CDMA or EV-DO, or an asynchronous scheme such as GSM or WCDMA.

The first portable terminal 100 according to an embodiment of the present invention continuously calculates the position coordinates according to the movement route of the first portable terminal 100 at a predetermined cycle, and maps the continuously calculated position coordinates to the map image. The location data may be generated and transmitted to the second mobile terminal 200 through the mobile communication network 300. In addition, the first portable terminal 100 may also transmit to the weakness data server 400 through the mobile communication network 300.

The route data may not only indicate a movement path of the user of the first portable terminal 100 but also include image, text, audio, and video data according to a user's request. Such map data according to the present invention may include a movement route of the first portable terminal 100 reflecting a shortcut, a road situation, and the like which only the user knows.

In addition, when the first portable terminal 100 receives the direction data request message from the second portable terminal 200, the first portable terminal 100 displays the request message, and the user confirms the request displayed on the first portable terminal 100 to input the user's instruction. When the second mobile terminal 200 checks whether the requested route data is stored. If the route data requested by the second portable terminal 200 is stored, the first portable terminal 100 may transmit the sketch data to the second portable terminal 200 using the mobile communication network 300. For example, the first portable terminal 100 may transmit the map data to the second portable terminal 200 in the form of a multimedia message (MMS).

The second portable terminal 200 can selectively measure its own location. That is, the second portable terminal 200 may mount a predetermined positioning program or measure its own position. However, the second portable terminal 200 according to the present invention may be a terminal that cannot measure its position. For example, when the second portable terminal 200 is equipped with a GPS module, the navigation service is preferably provided. The second portable terminal 200 may position its position regardless of whether the mobile communication network is connected in a synchronous or asynchronous manner like the first portable terminal 100. The second portable terminal 200 may display the sketch data when receiving the sketch data from the first portable terminal 100 through the mobile communication network 300. In another embodiment, the second portable terminal 200 may request the route data from the first portable terminal 100 to receive and display the corresponding route data. Here, when the second mobile terminal 200 includes the GPS module, the GPS data may be displayed by activating the GPS module. In addition, when the second mobile terminal 200 cannot measure its own location, for example, when the second mobile terminal 200 does not have a GPS module, the first mobile terminal 100 converts the weakness data into an image file and performs the second mobile. The second mobile terminal 200 may receive and display the map data in an image.

In this case, when the map data does not correspond to the size of the display unit of the second mobile terminal 100, the second mobile terminal 200 converts at least one of the accumulation, resolution, and size of the map data to correspond to the size of the display unit. It can be displayed on the display unit. However, if the user requests to display the received route data without conversion, the image conversion unit displays the original size of the route data, and the user can browse the route data using the direction key or the site key.

Hereinafter, a detailed description of the first mobile terminal 100 according to the embodiment of the present invention will be described with reference to FIGS. 2A and 2B. Here, since the configuration of the second portable terminal 200 according to the embodiment of the present invention is the same as that of the first portable terminal 100, a detailed description of the configuration of the second portable terminal 200 will be omitted.
