Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a GPS (Global P
ositioning System: A mobile phone with a built-in receiver makes it possible to easily obtain detailed map information up to the destination and seamlessly use it anywhere on the ground or underground or in a building structure. The present invention relates to a navigation system using a mobile phone with a GPS function that can be used. The above-mentioned mobile phone includes all mobile terminal devices such as PHS and PDA.

2. Description of the Related Art Conventionally, when visiting a destination on a strange land, the destination has been reached while checking roads, landmarks, and addresses drawn on the map by relying on a map book or the like. Further, in a car equipped with a car navigation system (hereinafter simply referred to as a car navigation system), the user arrives while obtaining navigation information by displaying a monitor screen or voice guidance by inputting a destination in the car navigation system.

The operating principle of the car navigation system is based on GPS, and GPS signals transmitted from a plurality of GPS satellites flying on the earth are received by a GPS antenna,
The position of the satellite is specified by analyzing the satellite position, the inter-satellite receiver distance information and the clock information included in the PS signal. The number of the plurality of GPS satellites must be at least 4 or more. Although the single positioning accuracy of GPS is generally a little over 10 m, it can be improved to 5 m or less by adopting DGPS (Differential GPS).

[0004]

However, the method of reaching the destination by relying on the above-mentioned atlas and the like has a drawback that the scale is too coarse for a commercially available atlas and the detailed portion is difficult to understand. The map drawn by the above has a drawback that the amount of information is insufficient or the judgment is incorrect due to incorrect information. A more serious problem is that even if the north, south, east, and west cannot be accurately grasped on a strange land, it cannot even be compared with a map.

Further, in the method of reaching a destination by a car equipped with a car navigation system, the car navigation system has all the map information stored in a CD-ROM or a DVD and has many functions, and the price is very high. However, there was a problem that it has not spread enough. Further, since the monitor screen is relatively large, there is a problem in size and weight even in a model that can be detached and used as a portable device.

The present invention has been made in order to solve the above problems, and it is possible to easily obtain detailed map information up to the destination, as well as above ground and underground or inside a building structure, etc. It is an object of the present invention to provide a navigation system using a mobile phone with a GPS function that can be used seamlessly in any place.

[0007]

In order to solve the above problems, in a navigation system using a mobile phone with a GPS function according to the present invention, a mobile phone with a GPS function in which a GPS receiver, a GPS controller and a GPS antenna are built in the mobile phone. GPS transmitted from multiple GPS satellites by phone
Means for receiving signals, position information obtained by analyzing satellite position, satellite inter-receiver distance information, clock information, etc. included in the plurality of GPS signals, telephone number and search information of the GPS function-equipped mobile phone. And a means for transmitting data such as a packet, and detecting the position of the mobile phone with GPS function and the destination by receiving the data to obtain map data of appropriate scale, route information, and map data such as distance with the mobile phone with GPS function. A map service center having means for transmitting to a telephone is provided and configured.

The GPS signals # 1, # 2, # 3, and # 4 are sent to the GPS receiving section 1 in the mobile phone 5 with the GPS function on one side.
3 and GPS control unit 14 concerned GPS signals # 1, #
The position information of the mobile phone 5 with the GPS function is obtained by analyzing the satellite position, the inter-satellite receiver distance information, the clock information, etc. included in Nos. 2, # 3 and # 4. Similarly, GPS signals # 1 and #
2, # 3 and # 4 are connected to the G by the GPS receiving unit 13 and the GPS control unit 14 inside the other mobile phone 5'having a GPS function.
GPS information is analyzed by analyzing the satellite position, satellite inter-distance distance information, clock information, etc. included in the PS signals # 1, # 2, # 3, # 4.
The position information of the mobile phone 5'with a function is obtained.

Then, data such as the position information and the telephone number of the mobile phone 5 with GPS function and the telephone number of the other mobile phone 5'with GPS function as search information is transmitted from the mobile antenna 7 through a packet network (not shown). The packet is transmitted to the packet base station 9. On the contrary, data such as the location information and the telephone number of the mobile phone 5'with GPS function and the telephone number of the mobile phone 5 with GPS function of the other party as the search information are packetized from the mobile antenna 7'through a packet network (not shown). The packet is transmitted to the base station 9.

The above data is transmitted to the WEB server, the firewall server, the map database server 12 and the like in the map service center 11 via the Internet 10. Then, the map database server 12 detects the positions of the other parties and creates map data such as map information and route information and distance on an appropriate scale, and the mobile phone 5 with GPS function and the GPS on the reverse route.
Send to mobile phone with function 5 '. Since a series of these operations are processed at high speed in real time, the display of the monitor screen 8 of the mobile phone 5 with GPS function and the monitor screen 8'of the mobile phone 5'with GPS function is smooth.

FIG. 4 is an example of a monitor screen in the second embodiment of the navigation system using the GPS function-equipped mobile phone according to the present invention. The GPS function-equipped mobile phone 5 owned by himself is displayed on the monitor display 8 of the GPS function-equipped mobile phone 5. The position of is marked with A, and the position of the mobile phone with GPS function 5'owned by the other party is marked with B.

When the distance to the other party's position B is relatively long at the beginning of the position search, coarse map data is displayed like the monitor display 8c, and as the other party's position B is approached, the monitor display 8d is displayed. The map data has a fine scale. At this time, for example, road traffic restrictions, construction information, etc. are stored in the map database server 1 of the map service center 11.
When the number is input to 2, it is preferable that the passable route is displayed as the arrow of the monitor display 8d by reflecting the information. Furthermore, it is suitable for the visually impaired and the like to output the soundable route through a speaker.

In the description of the first and second embodiments, GPS signals # 1, # 2, # 3, and # 4 are GPS satellites 1, 2, 3, and 4 that are flying on the earth. Although it is drawn to be received directly from the applicant, Japanese Patent Application No. 2 by the applicant of the present application
