The present invention relates to an AV system for guiding the movement of a moving object using an AV (Audio and Video) system installed in the mobile communication terminal and a mobile body integrated with a navigation system and a mobile navigation system for a mobile communication terminal.

With the development of the position acquisition technology using the Global Positioning System (GPS) and the field of telematics, a multimedia system used in a moving object such as a vehicle, the need for a low-cost navigation system is steadily being raised.

The navigation system includes a position acquisition module for acquiring current position information of a predetermined moving object, a path calculating module for calculating a moving path of the moving object, and a route guidance module for guiding the calculated moving path. In addition, in order to provide additional services, a broadcast wave such as DMB (Digital Multimedia Broadcasting) or FM (Frequency Modulation) broadcasting or a mobile communication means such as CDMA (Code Division Multiple Access) or GSM (Global System for Mobile communication) may be used. .

However, since the broadcast waves cannot communicate with each other, a mobile communication means such as CDMA or GSM that can communicate with each other is basically required, and the cost of the CDMA modem or GSM modem generated by the broadcast waves is difficult to develop a low-cost navigation system. Is giving.

In order to solve this problem, a navigation system capable of autonomous navigation is integrally incorporated into a mobile communication terminal, which is being carried by many users, and a navigation system built in the mobile communication terminal is used when a user moves a moving object, for example. Many efforts have been made to be able to be guided by the movement path from the current position of the moving object to the destination.

However, the mobile communication terminal basically has to limit the screen size of the display unit as a user should be able to easily carry and make a phone call. Therefore, the mobile communication terminal cannot manufacture a large screen size of the display unit, and thus, the navigation system provided in the mobile communication terminal is limited to display the surrounding map on the display unit based on the current position of the mobile unit. . That is, when guiding the movement of the moving object while displaying a high-scale map on the screen of the display unit, there is a limit in transferring information of adjacent neighbors based on the current position of the moving object. In addition, when guiding the movement of the moving object while displaying a map of a low scale on the screen of the display unit, the surrounding information adjacent to the moving object can be accurately transmitted to the user, but the surrounding information that can be transferred is too limited.
In addition, the mobile terminal preferably uses power charged in a battery to minimize power consumption. In order to reduce the power consumption of the battery, the mobile communication terminal limits the level of the guide voice signal output to the built-in speaker. Therefore, when the level of the guide voice signal output to the speaker is low and there is a lot of noise in the surroundings, the user does not correctly hear the guide voice signal output from the speaker, which causes the user not to be guided correctly by the movement of the moving object. There were three problems.
