Description

  The present invention relates to a portable terminal device, a method, and a system that perform short-range communication.

  2. Description of the Related Art Conventionally, in a communication technique for transmitting / receiving data between a plurality of devices, there is a short-range communication in which data is transmitted / received by wireless communication within a short range. In recent years, short-range communication has been standardized in mobile terminal devices such as mobile phones as a result of the reduction in size and power consumption of devices.

  So-called passing communication is performed between portable game machines and the like using the short-range communication installed in the standard. Passing communication is a communication that is automatically performed in a short time when software corresponding to a portable game machine is operated in a specific mode and one game machine recognizes the other game machine in the same state within the communication range. That means. For example, while the compatible software of each game machine is set to the passing communication mode, radio waves are alternately transmitted without performing a special operation, and one game machine has the same function operating. Detect game machines. Therefore, when two players approach while holding the game machine in this state, communication is established between the game machines even if the players are not aware of each other.

  In addition, the invention of Patent Document 1 is known in which wireless communication that is preferentially transmitted and received in such near field communication is prevented from becoming difficult. Japanese Patent Application Laid-Open No. 2004-151561 discloses a technique for short-range transmission of priority control data indicating that the priority of short-range transmission of service data by itself is higher than short-range communication between portable game devices. According to this invention, when the portable game device transmits / receives a communication request and sets another portable game device as a communication partner for short-range communication, attempts to receive priority control data, and receives priority control data, Prohibit short-range communication with other portable game devices.

It is a figure which shows an example of the display of the portable terminal device 10 which concerns on one Embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a functional block diagram illustrating operation functions of the mobile terminal device 10 and the mobile terminal device 20 and the message management server 30 according to an embodiment of the present invention.

  The mobile terminal device 10 performing near field communication includes a position specifying unit 11 as a position specifying unit, a one time ID acquiring unit 12 as a one time ID acquiring unit, a short range transmitting unit 13 as a short range transmitting unit, and a message as a message receiving unit. A short distance receiving unit 15; a passing determination unit 16 as a passing determination unit; and a message transmission enabling unit 17 as a message transmission enabling unit. Then, the mobile terminal device 10 transmits the one-time ID and the position specifying data of the mobile terminal device 10 together with a message at a short distance. Further, the message is received at a short distance together with the one-time ID and the position specifying data transmitted by another device, and the predetermined position is determined based on the received position specifying data and the position specifying data of the mobile terminal device 10 specified when the message is received When it is determined that the message has been received from a short distance within the range, the message of the mobile terminal device 10 can be transmitted to the message management server using the received one-time ID. The mobile terminal device 20 has the same configuration as the mobile terminal device 10.

  In short-range communication, information is transmitted and received between adjacent devices (for example, tens of centimeters to several tens of meters) using radio waves in a specific frequency band.

  The position specifying unit 11 acquires position specifying data specifying the position of the mobile terminal device 10. For example, the position specifying unit 11 specifies the position (latitude and longitude) of the mobile terminal device based on GPS data received from a GPS satellite.

  The one-time ID acquisition unit 12 acquires a one-time ID temporarily issued by the message management server 30 that manages message communication. That is, the one-time ID acquisition unit 12 requests the message management server 30 to issue a one-time ID, and acquires the one-time ID issued by the message management server 30 in response to the request.

  The one-time ID is identification information for performing communication and is identification information that can be used only once. The message management server 30 issues a one-time ID to the mobile terminal device 10 that has requested the issuance of a one-time ID, and stores the identification information of the mobile terminal device 10 and the issued one-time ID in association with each other. . Therefore, the apparatus which acquired one-time ID can communicate with the portable terminal device 10 only once via the message management server 30 by acquired one-time ID. That is, the user who has acquired the one-time ID can send a message to the user who sent the one-time ID without knowing the personal information of the user who sent the one-time ID.

  The short-range transmission unit 13 performs short-range communication with another mobile terminal device 20, the one-time ID acquired by the one-time ID acquisition unit 12, and the location specification data of the mobile terminal device 10 acquired by the location specification unit 11 , Is sent with the message.

  For example, the short-range transmission unit 13 automatically detects that the other mobile terminal device 20 can be received by short-range communication, and performs so-called passing communication.

  The message receiver 14 receives a message transmitted from the message management server 30 by another mobile terminal device 20.

  The short-range receiving unit 15 performs short-range communication with another mobile terminal device 20 and receives a message together with the one-time ID and the position specifying data transmitted by the other mobile terminal device 20.

  The passing determination unit 16 is based on the position specifying data received by the short distance receiving unit 15 and the position specifying data of the mobile terminal device 10 acquired by the position specifying unit 11 when the short distance receiving unit 15 receives the short distance. It is determined whether the receiving unit 15 has received from within a predetermined range. Here, the position specifying data (for example, latitude and longitude) received by the short distance receiving unit 15 is the position of the other party who has transmitted, and the mobile phone acquired by the position specifying unit 11 when the short distance receiving unit 15 receives it. The position specifying data (for example, latitude and longitude) of the terminal device 10 is the position of the terminal device 10 that has received it. In other words, the passing determination unit 16 determines that the position (for example, latitude and longitude) of the partner at the time of communication is within a predetermined range (for example, the calculated distance is a predetermined distance). It is determined whether it is within the range. Then, the passing determination unit 16 determines that the passing communication is within the predetermined range, and determines that the passing communication is not within the predetermined range. Further, when the passing determination unit 16 determines that the passing communication is not performed, the passing determination unit 16 discards the message received by the short-range communication. Even a message received by short-range communication is not passing communication, so by discarding the message, it is possible to receive a message only from a person who has actually passed.

  For example, the passing determination unit 16 stores the determination of passing communication in the passing history storage unit (see the passing history table in FIG. 3 described later). As a result, even if the user later notices that they have passed each other, messages can be exchanged using the one-time ID as long as the one-time ID is valid.

  The position specifying data may be acquired periodically (for example, every 3 seconds) during the passing communication. That is, the position specifying unit 11 may receive GPS data from GPS satellites periodically (for example, every 3 seconds) and acquire its own position specifying data calculated based on the received GPS data. When the short-range receiving unit 15 receives, it is possible to use the immediately preceding position specifying data that has already been calculated, so it is easier to get compared to the case where the position specifying data cannot be acquired or it takes time to acquire. Communication determination can be made more accurate.

  When the passing determination unit 16 determines that the short-range receiving unit 15 has received from within a predetermined range, the message transmission enabling unit 17 receives a message input, and the received message is sent to the short-range receiving unit. 15 enables transmission to the message management server 30 by the one-time ID received. If the passing determination unit 16 does not determine that the short distance receiving unit 15 has received from within a predetermined range, the received message is discarded. That is, when the passing determination unit 16 determines that the passing communication is the passing communication, the message transmission enabling unit 17 receives a message to be transmitted to the passing partner, and receives the received message through the passing communication. The message can be transmitted to the message management server 30 based on the ID, and when it is determined that the communication is not passing, the received message is discarded.

  The message management server 30 includes a one-time ID issuing unit 31 as a one-time ID issuing unit, a one-time ID destination managing unit 32 as a one-time ID destination managing unit, a message transferring unit 33 as a message transferring unit, and a one-time ID destination. One-time DB 34 (database) is provided as storage means.

  The one-time ID issuing unit 31 issues a temporary one-time ID in response to a request from the mobile terminal device 10.

  The one-time ID destination management unit 32 stores the issued one-time ID and address information as identification information of the mobile terminal device 10 in association with each other in the one-time DB 34 (see FIG. 4 described later).

  The message transfer unit 33 acquires address information associated with the received one-time ID based on the one-time DB 34 in response to receiving a message together with the one-time ID from another device, and acquires the acquired address information. The received message is transferred based on

  FIG. 2 is a block diagram illustrating an example of a hardware configuration of the mobile terminal device 10 according to an embodiment of the present invention.

The GPS receiving unit 2500 performs processing based on the received GPS data and calculates position data.

  FIG. 3 is a diagram illustrating an example of a passing history table of the mobile terminal device 10 according to an embodiment of the present invention.

  The passing history table stores time information that is a passing time, a passing position that is a passing place, a one-time ID that is received by passing communication, and a message that is received by passing communication. If it is determined that the communication is not passing, it is stored that the message has been discarded. By storing that the message has been discarded, the setting of a predetermined range for determining passing communication can be adjusted. The passing position may store not only the latitude and longitude as position specifying data when received at a short distance but also an address obtained based on the latitude and longitude. When the passing history table is displayed, it is possible to directly grasp where the passing is.

  FIG. 4 is a diagram showing an example of the one-time DB 34 of the message management server 30 according to an embodiment of the present invention.

  The one-time DB 34 stores the one-time ID issued by the message management server 30 and the address information of the mobile terminal device 10 that has requested the issuance of the one-time ID in association with each other. Based on the one-time DB 34, the message management server 30 can transfer the received message to the mobile terminal device 10 having the address information associated with the received one-time ID.

  FIG. 5 is a flowchart showing the processing contents of passing communication between the mobile terminal device 10 and the mobile terminal device 20 and the message management server 30 according to an embodiment of the present invention.

  In step S101, the mobile terminal device 10 requests a one-time ID. More specifically, the CPU 1010 transmits a one-time ID query requesting a one-time ID to the message management server 30. Thereafter, the CPU 1010 advances the processing to step S102.

  In step S201, the message management server 30 receives the one-time ID query and issues a one-time ID. More specifically, the message management server 30 issues a one-time ID based on the received one-time ID query and transmits it to the mobile terminal device 10. Then, the message management server 30 associates the issued one-time ID with the address information of the mobile terminal device 10 that has transmitted the one-time ID query, and stores them in the one-time DB 34.

  In step S102, the mobile terminal device 10 receives and stores the one-time ID transmitted by the message management server 30, and then acquires the position specifying data. More specifically, the CPU 1010 acquires the position specifying data specifying the position of the mobile terminal device 10 based on GPS data received from four or more GPS satellites from the GPS receiving unit 2500 and stores it. Thereafter, the CPU 1010 advances the processing to step S103.

  In step S103, the mobile terminal device 10 transmits a message together with the stored one-time ID and position specifying data. More specifically, the CPU 1010 transmits a message (for example, character A!) Together with the stored one-time ID and position specifying data to the mobile terminal device 20 via the short-range communication unit 1500. Thereafter, the CPU 1010 advances the processing to step S104.

  In step S301, the mobile terminal device 10 receives a short distance. More specifically, the CPU 1010 receives a message together with the one-time ID and position specifying data transmitted by the mobile terminal device 20. Thereafter, the CPU 1010 advances the processing to step S302.

  In step S302, the portable terminal device 10 determines passing. More specifically, the CPU 1010 includes the received position specifying data (latitude and longitude of the mobile terminal device 20) and the position specifying data (latitude and longitude of the mobile terminal device 10) acquired from the GPS receiving unit when received. Based on the calculated distance, it is determined whether or not the calculated distance is within a predetermined range (for example, within 5 m). That is, the CPU 1010 determines that the communication is passing communication when the calculated distance is within a predetermined range (for example, within 5 m), and passes when the calculated distance is not within the predetermined range (for example, within 5 m). Judge that it is not communication. Thereafter, the CPU 1010 shifts the processing to step S303.

  The portable terminal device 10 stores a passing history in step S303. More specifically, the CPU 1010 stores a communication record (communication time information, position information, one-time ID, message, etc.) in the passing history table. When the CPU 1010 determines that the communication is not passing communication, the CPU 1010 deletes the received message and stores the deleted flag. Thereafter, the CPU 1010 advances the processing to step S304.
