The present invention relates to a mobile communication terminal and a service method using the same, and more particularly, to a multi-party call system and a service method of the mobile communication terminal.

Recently, wired and wireless communication technology is rapidly developing. In addition, various services based on wired / wireless communication technologies provide convenience to users' lives. A representative example of this is a multi-party call service that allows several people to talk simultaneously. It is not easy for many modern people to talk together in one place. Therefore, the multi-party call service that can overcome the time or space constraints using wired / wireless communication and allow multiple people to send and receive a message together is more useful than any other service.

The method of connecting a multi-party call in the multi-party call service currently provided by wire / wireless communication companies is divided into two types as follows. A person participating in the conference call is A, B, C, and D, and it is assumed that A is a case where B, C, and D call B, C, and D as parties to the conference.

The first method is to make one call to the other party participating in the conference. That is, A makes a call to B and secures a call through predetermined call processing. With C on hold, C is called to obtain a call for A, B, and C to talk together. In the same way, while waiting for B and C, D is dialed to secure a call for A, B, C, and D to talk together, and A, B, C, and D participate in the conference.

The second method is to classify the parties who want to have a conference call into a group and store the phone number information in the conference server. That is, A stores the telephone numbers of B, C, and D as a group, for example, in the conference server that provides the conference. Similar to the case of listening to a voice message, a specific number (for example, * 89, etc.) is input to access the server providing the conference call, and the group is selected to make a conference call.

However, the conventional multi-party call connection method described above has the following problems.

In the first method, as more people participate in a call, a problem arises that the number of phone numbers inputted by the first caller increases, and the number of numbers to remember also increases. Therefore, the error is likely to occur when entering the phone number, it takes a lot of time for everyone to join the call. In addition, a problem arises that call participants have to wait boringly while listening to a telephone number button input sound or a call waiting sound until the connection of the last call participant is completed.

In the second method, the time required for entering the phone number is shorter than the first method, but it can be used only when the phone numbers are stored in the conference server in advance by grouping the called parties. The burden arises. In addition, once a group has been assigned, it is not easy to select only some of the group members and connect the phone. In other words, since the phone numbers are stored in advance for each group, when one group is selected, all the members of the group are connected to the phone. You have to go through the work of constructing. Therefore, it is difficult to select the desired counterpart rooms easily.

On the other hand, in a multi-party call, the first caller attempts to talk to a plurality of parties, but the call is attempted according to the circumstances of the other party (for example, the mobile terminal is turned off or absent). Some of the plurality of parties may not be able to participate in the conference call. Therefore, even if there was a consensus or information transmission to the call participants before the multi-party call, it was not possible to receive information about the person who could not participate in the call due to sudden circumstances. That is, the people who participated in the multi-party call were inconvenient because there was no way to find out who is currently participating in the call until a mutual name was established.

An object of the present invention for solving the above problems, by transferring the list of the other party's phone number to the multi-party call server to connect the multi-party call call to each party in the multi-party call server, the movement that can shorten the multi-party call connection time The present invention provides a multi-party call system and a service method of a communication terminal.

According to another embodiment of the present invention, since the call parties can be selected from the list of phone numbers stored in the mobile communication terminal, the desired call parties can be easily selected, and the mobile communication terminal does not need to separately store the phone numbers or storage groups of the other parties. To provide a multi-party call system and service method.

According to another embodiment of the present invention, a multi-party call system and a service method of a mobile communication terminal capable of quickly transmitting data and reducing data transmission costs by delivering the counterpart phone number list by SMS are provided. .

According to another embodiment of the present invention, by providing a list of the other party's telephone number by using the wireless Internet to deliver the list of the other party's telephone number to provide a multi-party call system and service method of the mobile communication terminal have.

According to another embodiment of the present invention, a multi-party call system and a service method of a mobile communication terminal that can provide convenience for multi-party call by adding the other party even when the user of the mobile communication terminal is talking to a third party. To provide.

According to another embodiment of the present invention, the multi-party call server lists the information of the people who participated in the multi-party call and the information of the person who terminated the call during the multi-party call list and provides each participant to participate in the multi-party call. The present invention provides a multi-party call system and a service method of a mobile communication terminal that allow each person to easily find out the status of people who are currently participating in the multi-party call.

According to another embodiment of the present invention, the multi-party call server terminates only the conference call formed between the person who terminated the call even when some of the people who participated in the multi-party call terminated the call, and others continue the conference call. The present invention provides a multi-party call system and a service method of a mobile communication terminal, which can be used to terminate a multi-party call by terminating the entire multi-party call formed only when the power ends the call.

Lastly, according to another embodiment of the present invention, when the one of the people who participated in the multi-party call requests a secret call, the multi-party call server transmits the contents of the call between the person requesting the call and the other party to the other person. The present invention provides a multi-party call system and a service method of a mobile communication terminal to control the transmission so that a secret call service can be provided during a multi-party call.

In order to achieve the above object, a multi-party call system of a mobile communication terminal according to the present invention uses a phone book to input a plurality of counterpart phone numbers from a user. Data communication unit for transmitting to the call server; And a multi-party call setting unit configured to set a call between the multi-party call server and the mobile communication terminal when a user calls for a multi-party call.

Other objects and advantages of the present invention other than the above objects will become apparent from the detailed description of the embodiments with reference to the accompanying drawings.

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

1 is a block diagram of a multi-party call system of a mobile communication terminal according to the present invention.

2A and 2B illustrate an example of inputting a conference call counterpart in a mobile communication terminal.

3A and 3B are diagrams illustrating an example of delivering participant information to people who have participated in a conference call.

In the multi-party call system of the mobile communication terminal according to the present invention, a mobile communication terminal 100 requesting a multi-party call and a terminal of a user of the mobile communication terminal 100 and a plurality of counterparts in response to a request of the mobile communication terminal 100. It includes a multi-party call server 200 that provides a multi-party call between 300a, 300b, and 300c. The counterpart terminals 300a, 300b, and 300c may be, for example, various types of devices capable of communicating, such as a mobile communication terminal such as a mobile phone and a personal digital assistant (PDA) and a wired telephone.

The mobile communication terminal 100 includes a phone book 102, a data communication unit 104, and a conference call setting unit 106.

The phone book 102 stores various phone numbers stored by the user of the mobile communication terminal 100. The user of the mobile communication terminal 100 may select a plurality of counterparts who wish to have a multi-party call among various phone numbers stored in the phone number list 106.

In order to facilitate selection of a plurality of counterparts who wish to have a multi-party call, as shown in FIG. 2A, a check box 111 may be added in front of the list of phone numbers to select a counterpart who wants to make a call. In this case, it is preferable to include an additional input button 113 in case the phone number of the counterpart who wants the multi-party call is not stored in the phone book 102.

If you want to have a multi-party call with the other party not stored in the phone book 102, press the additional input button 113, and directly input the unstored phone number as shown in FIG.

That is, the user of the mobile communication terminal can easily select the other party's phone number through the phone book 106, and enters a manual phone number only for the phone number not stored in the phone book 106 to select the other party of the conference call. .

The data communication unit 104 generates a list of phone numbers input by the user (selected from the phone book or by a direct input method) for the multi-party call, and transmits the list to the multi-party call server 200. In this case, the other party's telephone number list may be generated and transmitted by SMS, or may use the wireless Internet.

In the case of transmitting the other party's phone number list by SMS, the data transmission cost is low, and in the case of using the wireless Internet, there is an advantage in that more data can be transmitted at once than SMS.

The multi-party call setting unit 106 enters a plurality of counterpart phone numbers and attempts to make a call, that is, when a user of the mobile communication terminal 100 presses a call button, between the user of the mobile communication terminal 100 and a plurality of counterparts. Set up a conference call for the conference. That is, the multi-party call is connected between the mobile communication terminal 100 and the multi-party call server 200 for the multi-party call.

The conference server 200 receives a counterpart phone number list from the data communication unit 104 and requests a conference call from a plurality of counterparts. When there is a response to the multi-call call request from the plurality of counterparts, the multi-party call set up between the mobile communication terminal 100 and the multi-party call server 200 is the counterpart terminal 300a or 300b having the response. , Up to 300c).

In this case, when the counterpart terminal is the mobile communication terminals 300a and 300b, the location information of the mobile communication terminals 300a and 300b is searched through a home location register 154. The calls for the multi-party call are connected through the Mobile Switching Center (150). In addition, in the case of the wired terminal 300c, a call may be connected through the public exchange 152.

In some cases, the user of the mobile communication terminal 100 may want to add a call to another party while talking to a third party.

If the user of the mobile communication terminal 100 requests a multi-party call during a phone call with a third party, the user sets a preset call call to the multi-party call. The multi-way call is requested using the input phone numbers, and if there is a response, the multi-way call is connected. In order to facilitate such a change, it is preferable to configure the multi-party call server 200 in an integrated manner with the mobile switching center 150 having a function of controlling an incoming / outgoing signal.

When the user of the mobile communication terminal 100 or some of the counterparts terminates the call, the multi-party call server 200 ends only a call formed between the other party who terminated the call and the multi-party call between other participants. Should be provided continuously. Then, the entire conference call formed only when all the conference participants have terminated the call.

The multi-party call server 200 mixes voices transmitted through a multi-party call. At this time, since the configuration of mixing the voice in the conference call is a commonly used technology, detailed description thereof will be avoided.

If one of the call participants requests a secret call with some of the other participants, the multi-party call server 200 provides a secret call function so that the contents of the call are not transferred to other people among those who have requested the secret call. can do.

The multi-party call server 200 also transmits information on the mobile communication terminal user and its counterparts to the mobile communication terminal user and each counterpart when the multi-party call is made. Examples of specific transmissions are shown in FIGS. 3A and 3B.

Immediately after the conference is connected, as shown in FIG. 3A, a list of the participants who are currently engaged is sent, such as "Currently ..... is joining the call." Make sure you know what's going on. In this case, the user name of the first mobile communication terminal 100 that has been dialed may be prominently displayed by a method of displaying a different color or font size or by adding a picture to the side.

If there is a person who ends the call in the middle, as shown in FIG. 3B, the other participant can be quickly informed of who is the person who terminated the call. .

4 is a flowchart illustrating a multi-party call service method of a mobile communication terminal according to the present invention.

FIG. 5 is a flowchart illustrating the service method illustrated in FIG. 4 as a relationship between participants in a multi-party call service.

First, the user of the mobile communication terminal 100 attempts to make a multi-party call by inputting the phone numbers of the counterparts who wish to make the multi-party call (S11). At this time, the phone number of the counterpart may select a phone number stored in the phone book 102 of the mobile communication terminal 100. In this case, in the case of the phone number not entered in the phone book 102, a method of directly inputting a phone number using the additional input button 113 during the selection of the counterpart phone number from the phone book 102 may be used.

Next, the data communication unit 104 generates the counterpart phone number as a list and transmits it to the multi-party call server 200 (S13).

Next, the conference call setting unit 106 connects a conference call between the mobile communication terminal 100 and the conference server 200 (S15). At this time, if the user of the mobile communication terminal 100 is talking to the third party, the call call formed for the call with the third party is set as the conference call.

Next, the multi-party call server 200 requests a multi-party call call to each of the counterpart phone numbers included in the counterpart phone number list (S17).

Next, the multiparty call server 200 determines whether there is a response from the counterpart terminals 300a and 300b (S19), and if there is no response, between the mobile communication terminal 100 and the multiparty call server 200. Ends the conference call formed at.

When there is a response from the counterpart terminals 300a and 300b, the multiparty call server 200 connects the multiparty call call to the counterpart terminals 300a and 300b (S21).

Next, the conference server 200 provides a conference call by mixing the voices transmitted through the conference call (S23). In this case, when any one of the multi-party call participants requests a secret call, the call content of the person requesting the secret call and its counterpart, that is, the secret call parties, may be controlled so as not to be transmitted to other participants.

Next, the conference server 200 creates a list of participants currently participating in the conference and transmits them to each participant (S25).

Finally, the conference server 200 determines whether all of the participants end the call, and if some part ends the call, terminates only the conference call formed between the person who terminates the call and continues between other participants. To provide a multi-party call. Then, the list of people who terminate the call is transmitted to another participant so that it is easy to determine who is currently in the call and who is in the middle of the call. If the power supply ends the call, the conference call service is terminated by ending the conference call.

According to the multi-party call system and service method of the present invention as described above, by passing the list of the other party's phone number to the multi-party call server to connect the multi-party call call to each party in the multi-party call server, multi-party call connection time Can be shortened. In this case, even when the user of the mobile communication terminal is talking with the third party, the other party may be added to provide a convenience for the multi-party call.

In particular, since the call counterparts can be selected from a list of phone numbers stored in the mobile communication terminal, desired call counterparts can be easily selected, and there is no need to separately store phone numbers or storage groups of the counterparts.

When transmitting the list of the other party's phone number by SMS, data can be delivered quickly and the data delivery cost can be reduced, and when using the wireless Internet, a large amount of the other party's phone number list can also be delivered quickly.

In addition, the information on the people who participated in the conference and the information of the person who terminated the call during the conference are listed and provided to each participant, so that each of the people who have participated in the conference is currently participating in the conference. Make it easy to recognize. In addition, even if some of the people who participated in the conference ends the call, only the conference call formed between the person who terminated the call is terminated, so that other people can continue to use the conference, and the power ends the call. The multi-party call can be selectively terminated by terminating the entire multi-party call.

Lastly, when one of the people participating in the conference requests a secret call, it controls the communication between the person requesting the call and the other party so that it is not delivered to the other person, thereby providing a secret call service during the conference. Can be.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
