If it is determined that the area to be set by the user is specified. At this time, the control unit 200 is the configuration information (e.g., the area designation start position, the region designation, such as the coordinates of all the sections (all sections of the region specified through the touch input) so that the above-described region is designated The actual latitude and longitude, the ratio of the map, the coordinates of the area touched by the user to designate the area, etc.) are checked and stored.

Thereafter, the control unit 200 generates area information including the setting information stored as described above, and transmits the generated area information to another portable terminal as necessary. Processing may be performed through the generation unit 202.

The counterpart portable terminal which has received the above configuration information processes the area designated by the user to be displayed on the actual map data using the received configuration information to display the corresponding area.

The area information generation unit 202 collects and stores setting information such as coordinates according to the touch of the map data by the user under the control of the controller 200, and generates area information by using the stored setting information. do.

The area information is generated in the form of a message to be transmitted to another portable terminal. The area information may be generated by configuring a header, a field including message content, and a field including setting information.

The field including the setting information may include a start coordinate of an area designated by a user, latitude, longitude information, aspect ratio information, and coordinates of areas touched by the user in the map data. Also, the set area can be confirmed. That is, the portable terminal receiving the area information checks the corresponding area by comparing the setting information with the actual map data, which will be described with reference to FIG. 4.

The setting information collecting unit 204 of the area information generating unit 202 checks and stores the coordinates of the position according to the touch by the user under the control of the area information generating unit 200, and then touches the user. If it is overlapped with the touch start position, it is determined that an area to be set by the user is designated.

Thereafter, the setting information collecting unit 204 sets setting information such as coordinates of all sections touched so that the above-mentioned region is designated (for example, a position at which the region designation starts, actual latitude and longitude at which the region designation starts, and a map). , The coordinates of the area touched by the user to designate the area, and the like. In this case, the setting information collecting unit may check the touch of the user by using the data provided from the touch managing unit 208.

The memory unit 206 includes a read only memory (ROM), a random access memory (RAM), and a flash ROM. The ROM stores microcode and various reference data of a program for processing and controlling the controller 200 and the region information generator 202.

The RAM is a working memory of the controller 200, and stores temporary data generated during execution of various programs. In addition, the flash ROM stores various updatable storage data such as a phone book, an outgoing message, and an incoming message.

The touch manager 208 detects a user's touch input under the instruction of the controller 200 to perform an operation according to the touch input. That is, when the user's touch input occurs, the touch manager 208 provides the controller 200 with the location of the corresponding point where the touch input occurred, or the data corresponding to the location of the point by the touch manager 208.
