The terminals 1b and 1c have the same configuration, and can be called by transmitting the other party's IP address during a call.
FIG. 4 is a diagram showing the operation of the embodiment, and the operation will be described according to the step indicated by S in this figure.
As described above, the wireless ID transmitter 4 periodically transmits its own ID (transmitter ID). When a terminal enters the communication area, the terminals 1a to 1c are connected to the wireless ID transmitter 4. The transmitter ID is received, and here, the user of the terminal 1a is described as a sender, and the users of the terminals 1b and 1c are described as receivers.

  For example, when the terminal 1a is within the communication range of the wireless ID transmitter 4 shown in FIG. 1, the sender carrying the terminal 1a operates the function button 12, the cross button 13, and the execution button 14. When the communication partner group (terminals 1a and 1b) is determined (S1) and then the call button 15 is pressed (S2), the control unit 18 transmits the transmitter ID from the wireless ID transmitter 4 via the communication unit 19. Is acquired (S3).

Subsequently, the control unit makes a call to the receiver's terminals 1b and 1c via the wireless communication device 3 and the communication network 2 by the communication unit 19 for calling, and transmits the transmitter ID and its own to the management server 5. A terminal ID given in advance to the terminal is transmitted (S4).
When the management server 5 receives the transmitter ID and the terminal ID from the terminal 1a (S5), the management server 5 searches the database information (not shown) based on the received terminal ID to identify the communication partner group of the terminal 1a ( S6) Transmits the transmitter ID received from the terminal 1a to the terminals 1b and 1c of the specified group via the communication network 2 and the wireless communication device 3 (S7).

As a technique for specifying the wireless communication device 3 with which the management server 5 can communicate with the terminals 1a and 1b, a technique normally used in mobile phone or PHS communication is used.
When the control unit 18 of the terminals 1b and 1c receives the transmitter ID from the management server 5 by the communication unit 19 (S8), the received transmitter ID is stored in the storage unit 20 as a sender location specifying table. The position name corresponding to the received transmitter ID is specified, and the position name is displayed on the display unit 11 as information indicating the current position of the sender as shown in FIG. 2 (S10). ).

Thus, since the current position of the sender is displayed in characters on the display unit 11 of the receiver's terminals 1b and 1c, the user on the receiving side can easily know the position of the sender, and the sender in this state. Will be able to talk to the recipient.
That is, when the sender speaks a word to be communicated to the receiver while holding down the call button 15 of the terminal 1a, the voice is input from the microphone 16, and the communication unit 19 transmits the voice signal as a voice signal. It is transmitted to the recipient's terminals 1b and 1c via the device 3. In the terminals 1b and 1c, the voice signal received by the communication unit 19 is converted into voice and output from the speaker 17 as the voice of the sender.

When the sender releases his / her finger from the call button 15 of the terminal 1 a and releases the press, the control unit 18 of the terminal 1 a notifies the transmission end via the wireless communication device 3, the communication network 2, and the wireless device 3 via the communication unit 19. To the receiver's terminals 1b and 1c, whereby the terminals 1b and 1c end the information indicating the current location of the sender.
Similarly, when the user of the terminal 1b or the terminal 1c is a sender, the current position can be displayed in characters on the display unit of the communication partner terminal.

The sender's terminal ID is sent from the management server together with the transmitter ID, and the user's attribute information (terminal name, terminal ID, user's name, user's name is associated with the user's terminal ID. If the table corresponding to the image etc.) is stored in the storage unit 20 together with the sender position specifying table, the attribute information can be displayed together with the current position of the sender.
According to the embodiment described above, the transmitter ID acquired from the wireless ID transmitter by pressing the call button of the terminal carried by the sender is sent to the management server via the communication network, and the transmitter ID is transmitted. When the management server transmits to the receiver's terminal via the communication network, the receiver's terminal compares the received transmitter ID storage table stored in the transmitter ID storage unit with the location name corresponding to the transmitter ID. Since the location name is specified and the sender is displayed as text on the display of the receiver's terminal, the sender does not have to bother explaining the current location to the receiver. The user can easily know the precise current position of the sender and can obtain an effect of pressing the button.

  In the above-described embodiment, the transmitter ID is transmitted from the sender terminal (for example, 1a) to the receiver terminal (for example, 1b, 1c) via the management server 5, and stored in the receiver's terminal. The sender's position is displayed on the display unit 11 using the sender location specification table stored in the unit 20, but from the sender's terminal (for example, 1 a) without using the management server 5. Since it is also possible to send the transmitter ID directly to the receiver terminals (for example, 1b, 1c) by the communication network 2 and the wireless communication device 3, the management server 5 can be omitted as a system. In the case of a large button system, it is desirable to intervene the management server 5.

  In the above-described embodiment, the storage unit of each of the terminals 1a to 1c has been described as having the table 19 for comparison. However, the management server 5 has the table for verification and the terminal of the sender (for example, When the transmitter ID is sent from 1a) to the management server 5, the management server 5 compares the transmitter ID with the table for specifying the sender location based on the transmitter ID, and sets the location name corresponding to the received transmitter ID. The position name may be specified and transmitted to the receiver's terminal (for example, 1b, 1c) as character information indicating the sender's current position, and displayed on the display unit of the receiver's terminal. .

  Furthermore, the terminal on the receiver side is not limited to a portable terminal, and may be a general PC.
