Description

[0001] The present invention relates to a position information providing method and a navigation terminal,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method and a navigation terminal for providing fine position information using a position correction function, and more particularly, And to a navigation terminal.

In recent years, as the mobile terminal and communication technology have developed, there has been an increasing need to utilize their own position on the move. For example, it is necessary to check their position in a navigation system for a car, Identifying and sharing with others is a prime example.

The technique used to identify a specific position is basically based on a GPS (Global Positioning System), and displays the present position information corresponding to the absolute position on the coordinate axis on the earth surface detected by the GPS receiver on the map In addition, apart from this, a method in which a user displays pre-specified absolute position information on a map through searching is often implemented.

For example, when a user wants to check a specific destination on a map rather than a current location, or when he or she searches for a detailed area that the user is interested in and shares the location with others on the map, It is possible to share the fine position information by confirming the corresponding position on the map through direct search and sharing the coordinate information with others.

For this purpose, in searching for a location on a map, a method of searching for a specific location such as a name or a building name or selecting an administrative address book from a list and directly typing the remaining location information is utilized. In this case, There is a disadvantage in that a wrong place can be searched due to a large number of selection operations and inconvenience, and there is a disadvantage that it is impossible to utilize the map information itself when searching for a search name or an administrative address not registered in the map information.

In addition, since the searched location information only informs the specific location or the central location of the administrative address, it is impossible to provide accurate location information.

For example, if a surrogate driver is informed of a specific place where a vehicle is located for a substitute driving service, it may be necessary to set a finely accurate position, such as an administrative address where the vehicle is parked, There is a need to provide information.

Referring to FIG. 1, the overall system includes a navigation terminal 10, a communication network 20, and a map providing web server 30.

The communication network 20 is a communication network that is a high-speed period network of a large communication network capable of a large-capacity, long-distance voice and data service, and may be a next generation wired and wireless network for providing Internet or high-speed multimedia service. When the communication network 20 is a mobile communication network, it may be a synchronous mobile communication network or an asynchronous mobile communication network. As an embodiment of the asynchronous mobile communication network, a WCDMA (Wideband Code Division Multiple Access) communication network is exemplified. In this case, although not shown in the drawing, the mobile communication network 20 may include a Radio Network Controller (RNC). Meanwhile, although the WCDMA network is exemplified, it may be a next generation communication network such as a 3G LTE network or a 4G network, or an IP network based on other IP.

Meanwhile, the storage unit 14 of the present invention is a non-volatile memory (NVM) that does not lose power even if power is not supplied and keeps stored data. The storage unit 14 includes a flash memory, an MRAM Access memory), a phase-change random access memory (PRAM), and a ferroelectric RAM (FRAM). Referring now to FIG. 3, in FIG. 3-a1, in the default address selection method, the default address selection method is selected by selecting the address list of the administrative address and the 'direct address input search'. On the other hand, in FIG. 3-a2, an input process is shown for inputting a sphere unit, a unit input in FIG. 3-a3, and a minimum unit address information for inputting a building unit in FIG. On the other hand, FIG. 3-b1 shows the initial screen of the text direct input method, FIG. 3-b2 shows the address and building name input, and FIG. 3-b3 shows the corresponding output.

The correction means 13c implements the map UI screen to the input / output unit 11 for correcting the minimum unit address information collected by the address information collection means 13b to a more accurate position.
