Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a conceptual diagram illustrating a communication method in a WLAN ad hoc mode using a mobile wireless terminal device according to an embodiment of the present invention.

The embodiment schematically illustrates a state in which a plurality of mobile terminal devices are connected and communicated through an ad hoc network.

Referring to FIG. 1, each mobile terminal device is connected to a WLAN ad hoc network network, and is connected to each other using the WLAN ad hoc network network to enable individual communication or multi-group electronic meeting.

2 is a flowchart illustrating a one-to-one voice call method according to an embodiment of the present invention.

The embodiment schematically illustrates a process in which two mobile terminal devices are connected in an ad hoc mode to make a voice call.

Referring to Figure 2, the overall operation will be described in detail as follows.

Step 201 is a process of setting up a WLAN ad hoc in the mobile terminal device.

WLANs basically have two transport modes: infrastructure networking and ad-hoc networking. In some cases, building-to-building networking can also be configured. Among the above transmission modes, the mode is set to a mode capable of ad hoc networking.

Step 202 is a process of checking whether the other party is connected to the WLAN ad hoc mode.

Ad-hoc mode is configured only with a terminal equipped with a wireless LAN and is not connected to an external network. In the ad hoc mode, communication is performed only between wireless LANs connected to the inside of the ad hoc mode. Therefore, in this step, it is checked whether the other party is connected to the WLAN in the ad hoc mode.

In the above step, if the counterpart mobile terminal device to be connected is not connected to the WLAN in the ad hoc mode, the call is terminated.

Step 203 is a process of checking whether the other party's mobile terminal device has a voice call program through the VoIP function.

The VoIP (Voice over Internet Protocol) is to use the data communication packet network that has been used for the Internet phone. Voice data is transformed into Internet Protocol data packets to enable calls over the public telephone network.

The protocol includes H.323, SIP, MGCP, and MEGACO. Among them, it is preferable to use H.323, which is generally used in Korea.

Detailed description of the VoIP protocol is already apparent to those skilled in the art, so the description thereof will be omitted.

In step 203, the call is terminated if the voice call program using the VoIP function does not exist in the counterpart mobile terminal device to which the call is to be connected.

Step 204 is a process of calling a counterpart mobile terminal device using an IP number.

Since the present invention uses the ad hoc network mode, the IP can be determined independently without following the guidelines of the International Internet Address Management Organization.

Steps 206 to 207 determine whether the counterpart mobile terminal device has received the call, and if so, perform a call with the counterpart.

The above embodiment schematically illustrates a process of building an electronic conference system using a plurality of mobile terminal devices connected in a WLAN ad hoc mode.

Referring to Figure 3, the process of building the electronic conference system in detail as follows.

Step 301 is a process of setting up a WLAN ad hoc in the mobile terminal device.

Step 301 is the same as step 201.

Step 302 is a process of running the conference call system program.

The conference system also preferably uses the VoIP protocol.

Step 303 is a process of informing the mobile terminal of the WLAN ad hoc network that a conference call has been established.

The method of notifying that the conference call is established to the mobile terminal device of the WLAN ad hoc network is to send a signal to all connected mobile terminal devices and to select only those who need to participate in the electronic conference, and the conference call is established at the IP address. It is possible to inform.

Step 304 is a process of waiting for a user connection.

After notifying that the electronic conference has been established in step 303, the personal mobile terminal device receiving the notification that the electronic conference has been established waits for access to the electronic conference.

Step 305 is a process of determining whether the passwords transmitted by the mobile terminal apparatus which attempted the connection match.

In step 303, if a specific number of people is notified that the electronic conference has been established, a password input is required so that only a specific number of persons who have received a signal indicating that the conference call has been established can be accessed, and the password has already been determined. Check if it matches Preferably, the password is input by the user inputting the password into the mobile terminal device and transmitting the password to the conference system program.

If a signal indicating that an electronic conference has been established in step 303 is sent to an unspecified number of people, this step may be omitted.

If the password does not match in the step, the step 304 is repeated.

Step 306 is a process in which the electronic conference takes place.

When the people needed for the e-meeting are finished, the e-meeting takes place.

As described above, it has been described with reference to the preferred embodiment of the present invention, but those skilled in the art various modifications and changes of the present invention without departing from the spirit and scope of the present invention described in the claims below I can understand that you can.

As described above, according to the present invention, if there is only a terminal with a built-in wireless LAN, the present invention can be easily implemented in a building office, a temporary event site, a warehouse of a distribution company, and the like where people move frequently. To make communication between people more convenient.
