Then, as in (7A), an invitation message from the mobile phone 200A as the master is displayed on the display 210 of the mobile phone 200B, and selectable “YES” and “NO” are also displayed. When “YES” is selected by the operator, Bluetooth communication with the mobile phone 200A is performed and a “connection response” is performed. And you can enter the chat as a slave. In the case of “NO”, the mobile phone 200A is notified to that effect and does not enter the chat.

(8) When the chat is started, a display area 212 for chat and a display 214 for chat are displayed on the display 210 of the mobile phone 200A or the mobile phone 200B, and the contents of the conversation are displayed on the display 210 of all participants. The Of course, a plurality of slaves are possible, and chat participation by three or more people is possible. There is only one master.
Master mobile phone 200A relays all conversation contents to each slave mobile phone 200B. That is, the network configuration at the time of chatting is a star type centering on the master mobile phone 200A. Accordingly, the mobile phone 200A as the master can control all communication contents. Further, even if the slaves are separated from the Bluetooth communicable distance, chatting is possible if the distance between the master and the slave (between the mobile phone 200A and the mobile phone 200B) is within the Bluetooth communicable distance.
(9) Since this chat uses a mobile phone terminal, chat participants can move freely. Therefore, the distance between the master and the slave may be longer than the Bluetooth communication possible distance. In that case, it is regarded as having left the chat. That is, in the mobile phone 200B that has left, the chat application 35B automatically ends. The mobile phone 200A, which is the master, detects that Bluetooth communication has become impossible, and the chat application 35A performs an exit process. The leaving process is to delete the device that has left the member and send a message to the other chat participants that the person has left the chat. Other participants will see a pop-up to that effect. Even if some chat participants leave, other members can continue chatting.
Further, when all the slaves have left the chat (when they go out of service or when the chat application 35B is terminated), the chat ends.
When the master ends the chat application 35A, the chat is ended even if there is a slave participant. Then, the chat participant automatically ends the chat.

Next, the chat application 35 </ b> A controls the Bluetooth communication module 302 to perform Bluetooth communication with another mobile phone 200 </ b> B via the Bluetooth antenna 301 and perform chat processing with reference to FIGS. 4 and 5. explain.
First, using FIG. 4, a protocol for Bluetooth communication performed between the mobile phone 200A and the mobile phone 200B will be described. As shown in the figure, the transmitting side (master, mobile phone 200A) is shown on the left side, and the receiving side (slave, mobile phone 200B) is shown on the right side. Each software has a two-layer structure. On the transmission side, there is a “Java (registered trademark) application” and “Bluetooth Master” in the lower layer. On the receiving side, there are “Java application” and “Bluetooth Slave” in the lower layer. In the initial state, the receiving Java application is not activated.
First, the Bluetooth application is activated on the mobile phone 200A (step S501). As a result, an instruction for service record registration (step S502) and device search (step S503) is issued from “Java application” to “Bluetooth Master”.
A device search is performed by the “Bluetooth Master” from the mobile phone 200A side (step S504).
In response to this, a response is made from the mobile phone 200B side (step S505).

When receiving this response, Name Request is performed from the mobile phone 200A side (step S506). This asks the device name of the mobile phone 200B that has responded.
In response to this, a device name is returned from the mobile phone 200B side (step S507).
The mobile phone 200A receives this device name and passes it to the “Java application” (step S508).
The “Java application” issues a service search instruction necessary for Bluetooth communication to “Bluetooth Master” (step S509). “Service search” is an inquiry about whether or not the partner (that is, the mobile phone 200B on the receiving side) has a chat application.
The “Bluetooth Master” starts an ACL link connection to the mobile phone 200B (step S511) and requests a service record (step S512).
In response to this, the mobile phone 200B returns a service record (step S513).
The mobile phone 200A receives this service record and passes it to the “Java application” (step S514).

From the received information, the “Java application” displays the communication partner on the display 210 of the mobile phone 200A, selects the communication partner, and issues a Java activation request (step S510).
Meanwhile, the mobile phone 200B side requests the mobile phone 200A for a service record (step S515). The mobile phone 200A returns its service record to the mobile phone 200B (step S516). Next, Name Request is performed from the mobile phone 200B side (step S517). In response to this, a device name is returned from the mobile phone 200A side (step S518). When these series of communications are performed, the ACL link is disconnected from the mobile phone 200B side (step S519). Then, in the mobile phone 200B, the Java application that is not started is started (step S521).
Next, a service request is made from the “Java application” on the mobile phone 200A side (step S520), and a service record request is made on the mobile phone 200B side (step S522).

In response to this, a service record is returned from the mobile phone 200B side (step S523).
The service record is transferred to the “Java application” on the mobile phone 200A side (step S524).
The “Java application” on the mobile phone 200A side makes a connection request (step S525), and transmits a Connect Open process to the mobile phone 200B (step S526).
On the mobile phone 200B side, the connection is thereby started (step S527).
Thereafter, both the mobile phone 200A and the mobile phone 200B are notified of the completion of connection to the “Java application” (step S528).
With this series of processing, chatting by Bluetooth communication between the transmission side and the reception side becomes possible.

An example of a communication procedure between the transmission side and the reception side will be described with reference to FIG. As shown in the figure, the software has a three-layer structure of “Java application”, “extended function”, and “VM or less” on both the transmission side (master) and the reception side (slave). The “Java application” is a chat program using Bluetooth communication described in Java. The “extended function” is an extension of Java so that processing suitable for the mobile phone 200 can be performed. “VM or less” is a Java virtual machine.
The sending side and the receiving side are already capable of chatting via Bluetooth communication according to the procedure described in FIG.
“Java application” performs listener registration (steps S601 and S602) on both the transmission side and the reception side. Listener registration is to confirm whether a chat message has been sent. The result that the character was sent to the other party can be acquired. A message is the content of a conversation in chat.
On the transmission side, the “Java application” subsequently transmits a message, which is the content of the conversation, to the “extended function” (step S603). Then, the “extended function” returns an identifier of the message to the “Java application” (step S604). Further, a message is output for “VM or less” (step S605), and the message is transmitted to the receiving side (step S607). Then, the transmission side waits for input (step S608).
On the other hand, on the receiving side, after step S601, the “extended function” waits for input to “VM or less” (step S606), and waits for transmission from the transmitting side. When a message from the transmission side (step S607) is received, a return is returned to the “extended function” (step S609). The “extended function” outputs an Ack indicating that it has been received (step S610), and returns it to the transmission side (step S611).
On the transmitting side, Ack from the receiving side is received and returned to the “extended function” (step S612).
By repeating this, a conversation of chat processing is performed.
This makes it possible to easily communicate with other people by chat.

FIG. 6 shows that when the chat application 35A is activated in the mobile phone 200A on the master side, it is detected whether or not Bluetooth setting is permitted, and if it is not permitted, the permission can be set. Is.
In step S420, activation of a chat program that is a Bluetooth application is selected according to an instruction from the operator of the mobile phone 200A.
In step S430, “Bluetooth on / off setting” is detected. As a result, if “ON”, the process proceeds to step S480, and if “OFF”, the process proceeds to step S440.
In step S440, since the Bluetooth setting is not permitted, first, a Bluetooth setting screen is displayed on the display 210 of the mobile phone 200A.
In step S450, an instruction to set Bluetooth on / off is given by the operation of the operator on the screen displayed in step S440. If it is “ON”, the process proceeds to step S470, and if it is “OFF”, the process proceeds to step S460.
In step S460, the operator remains off (not permitted) with the Bluetooth setting, so the screen returns to the initial screen and the Bluetooth application is not activated.
In step S470, since the operator has set the Bluetooth setting to ON (permitted), the “Bluetooth ON / OFF setting” is set to “ON”.
Step S480 is a case where “Bluetooth on / off setting” is “ON” from the beginning, or is set to “ON” in Step S470, and the chat program which is a Bluetooth application is started.
