Japanese Patent Laid-Open No. 2002-73611

The conventional information distribution system searches for a predetermined area covering the current position of the mobile phone. However, depending on the location, the user may desire information only about the current position and the vicinity of the current position, so that it is not easy for the user to use.

In order to solve the above-described problems in the prior art, the present invention includes a mobile communication terminal that includes a position information detection unit, wirelessly transmits acquired position information, includes an input unit, and wirelessly transmits an input search condition, and a map In an information distribution system comprising a database and a server device, searching the map database based on the position information and the search condition and distributing information, the search condition includes distance information or area information, and the position information and the The information in the area set by using the distance information or the area information as a factor is distributed.

  Further, in the server device that searches the map database based on the location information and search conditions of the information distribution request source wirelessly transmitted by the information distribution request source and distributes the information, the search condition includes distance information or area information, The information in the area set based on the position information and the distance information or the area information is distributed.

  Further, in a mobile communication terminal comprising position information detection means and input means, position information detected by the position information detection means in a server device, and a search condition including distance information or area information input by the input means Wireless transmission.

According to the present invention, by distributing the information in the area set by using the position information and the distance information or area information included in the search condition as a factor, the user can select a desired search area including the current position. It can be easily set by distance information or area information. Therefore, for example, in information-rich areas such as downtowns, the search area can be easily set to a small area by setting the distance information to a short distance or the area information to a small area, for example, a nearby restaurant, etc. It is possible to accurately obtain information that is most convenient for the user located in the immediate vicinity. Also, for example, the input operation is very simple, such as “100” m or area “large”, area “medium”, and area “small”, so that it is very easy to use.

Next, an embodiment of the present invention will be described. FIG. 1 is a diagram for explaining a system configuration example in which the present invention is applied to a mobile phone system. The mobile phone system includes a base station BS, a mobile device (mobile phone terminal) MS1, and a control device CS. The information source is an information distribution WEB site on the Internet, and is a data communication server (corresponding to a “server device”) SB, a map database MDB, a terminal designation information database (“search”, etc.) for identifying terminals and IDs. Condition registration database ”) TDB.

  FIG. 2 shows a block diagram of the mobile device MS1, which includes an antenna AT1, a duplexer DP, a receiving unit RX1, a transmitting unit TX, a data processing unit DSP1 such as encoding / decoding, a control unit DSP2 that controls the entire terminal, and voice Codec CODEC, speaker SP, microphone MIC, memory MEMORY, display LCD, operation unit for inputting search conditions (corresponding to “operation input unit”) KEY, and antenna AT2 and GPS receiving unit for receiving GPS satellite signals RX2 is provided. The reception information output from the GPS reception unit RX2 is obtained by the data processing unit DSP1 calculating the position information of the mobile device MS1 by calculating this, that is, calculating the current latitude and longitude. In addition, although it has a battery, a power supply circuit, etc., they are abbreviate | omitted.

  FIG. 3 is a flowchart of the mobile device MS1. In the present embodiment, the mobile station MS1 connects to the information distribution WEB site, and after the ID and password are entered and the matching with the one registered in the terminal designation information database TDB is confirmed.

  First, the user sets search conditions on the WEB using the mobile device MS1 (S101). There are two types of search conditions: information type and distance. Types of information include, for example, “restaurant information”, “sightseeing spot information”, and the like, which are displayed as menus on the display unit LCD. The user selects one or more desired types from the menu, checks the checkboxes of the selected items, and presses the send key. Thereby, the checked one is transmitted by radio and registered as a search condition in the terminal designation information database TDB together with the terminal identification information ID of the mobile device MS1. The type of the checked information is also registered in the memory MEMORY of the mobile device MS1.

  Subsequently, a distance setting screen is displayed on the display unit LCD. This distance is “the length of one side of the square serving as the search area”. For the setting, a desired number is input to the predetermined writing space in the displayed screen using the operation unit KEY. The unit of distance is “m”. For example, when a numeric part such as “100” m is entered and the transmission key is pressed, the distance specified by the entered number is transmitted as another search condition, and is transmitted to the terminal designation information database TDB. It is registered together with the terminal identification information ID. Similarly input distance information is also registered in the memory MEMORY of the mobile device MS1.

  FIG. 4 shows a registration table of the search condition registration database of the terminal designation information database TDB registered in this way. In the registration table of FIG. 4, up to three types of information can be registered.

  In FIG. 3, when the registration of the search condition in S101 is completed, the mobile device MS1 then starts transmitting position information (S102). While connected to the information distribution WEB site, the mobile device MS1 measures the position information with a GPS reception signal at a predetermined time interval (for example, every three minutes), and the position information (latitude, longitude) and its own terminal identification every time the position is measured. The information ID is transmitted to the information distribution WEB site.

  As will be described later, the data communication server SB receives the terminal identification information ID and the position information, and sets a search area based on this and the search conditions of the mobile device MS1 registered in the terminal designation information database TDB. Search the map database and distribute information.

  In FIG. 3, when the transmission of the location information in S102 is started, the mobile station MS1 waits for reception of distribution information (S103). When receiving the information, the mobile station MS1 displays the information on the display LCD (S104). The distribution information is text information including an information source name, address, and the like. When there are a plurality of search results, distribution is performed in order from the closest to the current position. FIG. 5 shows received information display example 1 and display example 2.

  Note that the data communication server SB may distribute image information in which the position and name of the information source are written in the map image corresponding to the set search area.

  When a predetermined time elapses during connection to the information distribution WEB site after receiving the information distribution, the process returns to S102 to measure and transmit the position information, and the above-described processing steps S102 to S104 are repeated.

  Next, FIG. 6 is a flowchart of the data communication server SB. In the present embodiment, the mobile device MS1 connects to the information distribution WEB site, inputs the ID and password, confirms the match with the one registered in the terminal designation information database TDB, and further searches the terminal designation information database TDB. It is a flowchart after conditions are registered.

  The data communication server SB waits for reception of position information in step S201. When the position information is received together with the terminal identification information ID, the terminal designation information database TDB is searched with the terminal identification information ID, and the search condition registered in the corresponding ID is read (S202).

  Subsequently, the map database is searched (S203). In the search, based on the position information received first and the distance information that is one of the read search conditions, the position information (latitude and longitude) is the center and one side is the length of the distance information, and A square in which four sides are combined in the direction of is set as a search area. The search area to be set, that is, position information (latitude and longitude) corresponding to the four corners of the square is derived, and the inside of the line connecting these four points is the search area.

  In the map database, information type, information source name (for example, “restaurant name”), location information and address (for example, “restaurant” longitude, latitude and address) are registered. And the information whose address is inside the search area is extracted.

  When the search is completed in this way, the searched information is distributed to the mobile device MS1 (S204). When distribution is performed, the process returns to step S201 again.

  As described above, the user can easily set the search area simply by operating the distance information from the portable terminal with a position detection function such as a portable telephone terminal with a GPS receiver.

  In the embodiment, “longitude” information and “latitude” information are used as position information. However, in addition to these, “altitude” information is used, and the search area can be a three-dimensional space.

  In addition, the distribution information is displayed as text information on the display unit LCD of the mobile device MS1, but the present invention is not limited to this. For example, the distribution information is voice information. The search area that is set using the position information and the distance information as factors is not limited to the above-described embodiment. For example, the distance information is centered on the position information. It is also possible to set the search area as a search area.

  Furthermore, although distance information is used in the embodiment, area information may be used as a factor for setting a search area instead of distance information. This can be easily realized by replacing the above-described distance setting screen for setting search conditions from the mobile communication terminal with an area setting screen. Preferably, three types of selection menus such as “large”, “medium”, and “small” are displayed on the display LCD on the setting screen of the mobile phone so that the user selects one of them. To do. Specific areas such as “large”, “medium”, and “small” are pre-defined in the server device by the Internet provider, and are specific to the user, for example, “100 m × 100 m”. There is no need to enter. By pressing a transmission key following selection, the selected area information is transmitted to the server device as one of the search conditions. The server device sets the search area using the position information and the selected area information as a factor, and the setting may be performed by setting the area of the selected area based on the position information by a predetermined setting method, for example, When the definition of the area is distance information × distance information, such as 100 m × 100 m, the setting can be performed in the same manner as in the case where the distance information is a factor.

  As described above, distance information and area information as search conditions, how to input them, how to set a search area in the server device, and other matters have been described. Is not limited to the above embodiment.
