In FIG. 11, the transmitting-side mobile terminal A 100-1 is fixed to the base via a spring, and the user holds the other-side receiving-side mobile terminal B 100-2 in his / her hand to fix the transmitting side. The case where it contacts with portable terminal A 100-1 is shown. As a result, the vibration measurement is performed, for example, at a rate of several times / second or more, and it is more likely to generate a highly similar vibration (for example, vibration data) instantaneously in a non-contact state. As a result, the communication partner can be reliably confirmed, and the information data to be communicated can be correctly transmitted only to the other parties who want each other, thereby improving the security.

  Although not shown in the drawing, this short-range communication system is a flexible system in which users can easily hold a mobile terminal by hand and easily receive vibrations without fixing the mobile terminal to a base via a spring as shown in FIG. The state may be realized. In this case, the communication may be realized by bringing the hands into contact with each other indirectly with the hand held in the hand, without touching the handheld terminal directly.

  In addition, although not shown, this short-range communication system has a sheet (for example, a signboard decoration that indicates a contact angle, a contact position, etc.) between a portable terminal of a partner who desires communication and his / her portable terminal (for example, , Laminated paper or the like) may be included. Thereby, the portable terminals can be brought into contact with each other by the method instructed on the sheet, and the user can easily perform data communication between the portable terminals. This is the end of the description of the configuration of the near field communication system.

[Processing of short-range communication system]
Next, an example of processing of the short-range communication system according to the present embodiment configured as described above will be described in detail below with reference to FIGS. In FIG. 12 and FIG. 13, for convenience of explanation, the step on the transmission side is “ST−” and the step on the reception side is “SR−”.

[Determination Processing in Receiving-side Mobile Terminals 100-2 to 3]
Details of the determination process in the reception-side portable terminals 100-2 to 3 will be described with reference to FIG. FIG. 12 is a diagram illustrating an example of determination processing in the reception-side mobile terminals 100-2 to 3 in the short-range communication system according to the present embodiment.

  First, the user places the receiving portable terminal B 100-2 within the radio wave range of the transmitting portable terminal A 100-1, so that the transmitting portable terminal A 100-1 and the receiving portable terminal B 100-2 Communication with each other occurs (step ST-1a and step SR-1a). At this time, there is a possibility that the radio waves of the transmitting-side mobile terminal A 100-1 reach the receiving-side mobile terminal C 100-3 that does not wish to communicate, and a communicable state may occur.

  That is, the transmission side displacement detection unit 102a and the reception side displacement detection unit 102d are activated by the processing of the activation unit 102k of the transmission side portable terminal A 100-1 and the reception side portable terminal B 100-2.

  And the transmission side portable terminal A 100-1 which received the electromagnetic wave and became in the communicable state was generated when the user brought the reception side portable terminal B 100-2 into contact with the transmission side portable terminal A 100-1. It measures its own shaking for a certain period, adds its characteristic amplitude to the normal message, and transmits it (step ST-2a).

  That is, the transmission side including at least vibration data and inclination data generated in the transmission side portable terminal A 100-1 due to the contact between the portable terminals by the processing of the transmission side displacement detection unit 102a of the transmission side portable terminal A 100-1 The displacement detection unit 10 of the transmission-side portable terminal A 100-1 is controlled to detect the displacement data. And the communication which incorporated the transmission side displacement data detected by the process of the transmission side displacement detection part 102a in at least one part of the data transmitted by the process of the communication data generation part 102b of the transmission side portable terminal A 100-1. Data is generated. And the communication data produced | generated by the process of the communication data production | generation part 102b are transmitted by the process of the transmission part 102c of the transmission side portable terminal A 100-1.

  Then, the receiving-side mobile terminal B 100-2 decodes the received electronic message, separates the data and shaking, measures its own shaking, obtains its characteristics, and receives the shaking characteristics and its own shaking. The time characteristics of the features are measured and compared, and when similarity is recognized with a certain probability, it is recognized as contact communication (step SR-2a).

  That is, the reception side including at least vibration data and inclination data generated in the reception-side portable terminal B 100-2 due to contact between the portable terminals by the processing of the reception-side displacement detection unit 102d of the reception-side portable terminal B 100-2. The displacement detection unit 10 of the reception-side mobile terminal B 100-2 is controlled so as to detect the displacement data. And the communication data transmitted by the process of the transmission part 102c from the transmission side portable terminal A 100-1 are received by the process of the reception part 102e of the reception side portable terminal B 100-2. And the communication data received by the process of the receiving part 102e are isolate | separated into transmission side displacement data and data by the process of the data separation part 102f of receiving side portable terminal B 100-2. The transmission side displacement data separated by the processing of the data separation unit 102f and the reception side displacement detected by the processing of the reception side displacement detection unit 102d by the processing of the similarity comparison unit 102g of the reception side portable terminal B 100-2. Compare similarity to data. And when the similarity compared by the process of the similarity comparison part 102g is within a predetermined range by the process of the approval part 102h of the reception side portable terminal B 100-2, the reception side portable terminal A 100-1 and the reception side The communication with the side portable terminal B 100-2 is approved. In addition, even if the receiving mobile terminal C 100-3 that does not wish to communicate is in the radio wave range of the transmitting mobile terminal A 100-1 and communication is possible, there is no contact action between the mobile terminals. Since the shaking of the receiving mobile terminal C 100-3 does not fall within the predetermined range of the shaking of the transmitting mobile terminal A 100-1, the receiving mobile terminal C 100-3 and the transmitting mobile phone Communication with terminal A 100-1 is not authorized.

  And the receiving side portable terminal B 100-2 notifies establishment of contact communication to the transmitting side portable terminal A 100-1 (step SR-3a).

  That is, after the communication is approved by the process of the approval unit 102h, the control unit 102-2 of the reception-side portable terminal B 100-2 stores the data separated from the communication data by the process of the data separation unit 102f. 2 and a communication success notification for notifying that the communication has been successful is transmitted.

  And the transmission side portable terminal A 100-1 confirms the communication success transmitted from the reception side portable terminal B 100-2, and stops communication (step ST-3a). Note that the transmission-side portable terminal A 100-1 may include a telegram activation after communication is established. In this case, the first transmission action is for searching.

  That is, the control unit 102-1 of the transmission-side portable terminal A 100-1 receives the communication success notification transmitted by the processing of the control unit 102-2 of the reception-side portable terminal B 100-2, and then transmits the communication data. Stop.

  Although not shown in FIG. 12, when the mobile terminals are brought into contact with each other in Step ST-2a and Step SR-2a, the process of the intersection angle estimation unit 102i is based on the transmission side displacement data and the reception side displacement data. You may estimate the crossing angle in the case of contact between portable terminals, and the contact position in the case of contact between portable terminals based on transmission side displacement data and reception side displacement data by the process of the contact position estimation part 102j You may guess.

[Determining process in transmitting portable terminal 100-1]
Next, details of the determination process in the transmission-side portable terminal 100-1 will be described with reference to FIG. FIG. 13 is a diagram illustrating an example of determination processing in the transmission-side portable terminal 100-1 of the short-range communication system according to the present embodiment. In FIG. 12, the mobile terminal A is a transmission-side mobile terminal A 100-1 that transmits communication data, and the mobile terminal B and the mobile terminal C are reception-side mobile terminals B 100-2 that receive communication data. Although described as the reception-side mobile terminal C 100-3, in FIG. 13, the mobile terminal A is the reception side, and the mobile terminal B and the mobile terminal C are the transmission side. Details are shown below.

  Note that step ST-1b and step SR-1b in FIG. 13 correspond to step ST-1a and step SR-1a in FIG.

  First, the mobile terminal B 100-2 that has received a radio wave and is in a communicable state has constant shaking of the mobile terminal B 100-2 generated by the user contacting the mobile terminal A 100-1 with the mobile terminal B 100-2. The mobile terminal C 100-3, which measures the period, adds the characteristic amplitude to the normal message, transmits it, and receives the radio wave and becomes in a communicable state, keeps its own shaking generated in a non-contact state constant. The period is measured, and the characteristic amplitude is added to the normal message and transmitted (step SR-2b).

  That is, the reception side displacement data including at least the vibration data and the tilt data generated in the mobile terminal B 100-2 when the mobile terminals come into contact with each other is detected by the processing of the reception side displacement detection unit 102d of the mobile terminal B 100-2. Thus, the displacement detection unit 10 of the portable terminal B 100-2 is controlled. And the communication data which incorporated the receiving side displacement data detected by the process of the receiving side displacement detection part 102d into at least one part of the data transmitted by the process of the communication data generating part 102b of the portable terminal B 100-2. Generated. And the communication data produced | generated by the process of the communication data generation part 102b are transmitted by the process of the transmission part 102c of portable terminal B 100-2. Note that the mobile terminal C 100-3 performs the same processing as the mobile terminal B 100-2.

  And portable terminal A 100-1 decodes the message | telegram received from portable terminal B 100-2 and portable terminal C 100-3, isolate | separates data and shaking, measures its shaking, acquires the characteristic, Then, the received shake characteristic and the time characteristic of the own shake characteristic are measured and compared, and when similarity is recognized with a certain probability, it is recognized as contact communication (step ST-2b). In FIG. 13, the displacement data (A) of the portable terminal A 100-1 is compared in similarity with the displacement data (B) of the portable terminal B 100-2 and the displacement data (C) of the portable terminal C 100-3. It is determined that the displacement data (A) and the displacement data (B) have close similarity, and the displacement data (A) and the displacement data (C) have distant similarity.

  That is, the processing of the transmission-side displacement detection unit 102a of the mobile terminal A 100-1 detects reception-side displacement data including at least vibration data and inclination data generated in the mobile terminal A 100-1 when the mobile terminals contact each other. Thus, the displacement detection unit 10 of the mobile terminal A 100-1 is controlled. And the communication data transmitted by the process of the transmission part 102c from the portable terminal B 100-2 and the portable terminal C 100-3 are received by the process of the receiving part 102e of the portable terminal A 100-1. And the communication data received by the process of the receiving part 102e by the process of the data separation part 102f of portable terminal A 100-1 are changed into the communication data of portable terminal B 100-2, and the communication data of portable terminal C 100-3. Are separated into transmission side displacement data and data. The transmission side displacement data separated by the processing of the data separation unit 102f and the plurality of reception sides detected by the processing of the reception side displacement detection unit 102d by the processing of the similarity comparison unit 102g of the portable terminal A 100-1 Compare similarity with displacement data. And when the similarity compared by the process of the similarity comparison part 102g is in a predetermined range by the process of the approval part 102h of portable terminal A 100-1 (in FIG. 12, displacement data (A) and displacement data) When (B) has close similarity), communication between the mobile terminal A 100-1 and the mobile terminal B 100-2 is approved. On the other hand, when the similarity compared by the process of the similarity comparison unit 102g is not within the predetermined range (in FIG. 12, when the displacement data (A) and the displacement data (C) have distant similarity), the mobile terminal Communication between A 100-1 and portable terminal C 100-3 is not approved. That is, even when the mobile terminal C 100-3 that does not desire communication is in the radio wave range of the mobile terminal A 100-1 and communication is possible, the mobile terminal C 100 if there is no contact action between the mobile terminals. Since the similarity with the shaking of the mobile terminal A 100-1 does not fall within a predetermined range, the communication between the mobile terminal C 100-3 and the mobile terminal A 100-1 is not approved.

  And portable terminal A 100-1 notifies establishment of contact communication only to portable terminal B 100-2 (step ST-3b).

  That is, after the communication is approved by the process of the approval unit 102h, the control unit 102-1 of the mobile terminal A 100-1 receives the communication data (the communication data received from the mobile terminal B 100-2 by the process of the data separation unit 102f). ) Is stored in the storage unit 106-1, and a communication success notification notifying that the communication is successful is transmitted only to the portable terminal B 100-2. This is the end of the description of the processing of the short-range communication system.
