Method for Operating Application Providing Group Call Service Using Mobile Voice Over Internet Protocol

The following embodiments relate to how an application that provides a group call service using the Mobile Voice Over Internet Protocol (mVoIP) operates.

In recent years, mobile voice over Internet protocol (mVoIP) networks have been constructed using the interlocking of mobile Internet (for example, Wybro, Mobile Wymax, 3GPP LTE, 4G LTE, etc.) and IMS (IP Multimedia Subsystem) networks. , Technologies for providing mVoIP-based call services (for example, voice call services, video call services, etc.) to mobile Internet subscribers as additional services have been developed.

mVoIP is a technology that provides voice over Internet Protocol (Voice over IP) services at the voice telephone level using data services of the mobile Internet network. VoIP services may be classified into fixed VoIP services and mVoIP services according to the degree of mobility. That is, a mobile Internet-based VoIP service such as a mobile communication network may be classified as an mVoIP service.

On the other hand, the instant message service is a service that supports real-time text communication between two or more people using a network such as the Internet. Instant messenger is a client that relays real-time messages. Instant messaging services differ from email services in that they interact in real time. A transmission is made each time the interacting people type one line at a time, so this is more like a telephone dialogue than exchanging letters.

In addition, the group call service may include, for example, a conference call as a service that enables voice calls of three or more participants at a time.

Hereinafter, the description will be described in detail with reference to the drawings to which the embodiments are attached.

1A to 1B are diagrams for explaining a group call receiving method of an application that provides a group call service by using the mobile voice over Internet protocol (mVoIP) according to the embodiment.

Referring to FIG. 1A, the application according to one embodiment receives a request signal for a group call (110).

Here, the group call includes a voice call made by using mVoIP between three or more members. That is, the request signal for a group call contains request originator information and request recipient information, the request originator information includes information about one request originator, and the request recipient information includes at least two request recipients. May include information about.

However, in some cases, the group call may include a voice call made between two members using mVoIP. For example , a group call is required only if it contains three or more members, but the group call is retained even if only two members remain in the group call after the group call is started. Will be done.

The application also receives meta information from the server for group call chat rooms that support group calls, regardless of whether or not they participated in the group call (120). That is, the application may receive the meta information of the group call chat room from the server not only when the user participates in the group chat but also when the user does not participate in the group chat.

Hereinafter, the server may include, for example, an instant message server or an mVoIP server as a device that supports a group call service using mVoIP in conjunction with an application.

Here, the meta information received from the server may include at least the group call connection status of each member of the group call chat room. The application according to the other embodiment may receive meta information from the server including the group call connection status of each of the remaining members other than itself among the members of the group call chat room.

The group call connection state may include a state in which each of the plurality of members is connected to the group call, for example, a connected state, a connected state, an terminated state, and a connectable state. Here, the server may change the group call connection state to the end state if the connection state is maintained for a predetermined time (for example, 1 minute).

The application also provides an interface in which whether or not to join a group call is entered in response to the reception of the request signal (130). Here, the user inputs at least one of the input of "join now" in the group call and the input of "join later" in the group call using the interface (140).

The application also automatically enters a group call chat room that supports group calls by receiving an input to "join now" in a group call (150). Here, the group call chat room includes a chat room that performs functions similar to those of a normal instant message group chat room, but additionally provides additional functions for group calls. For example, a group call chat room may include multiple members and provide an instant messenger function that allows instant messages to be exchanged between multiple members, further providing voice call function using mVoIP among multiple members. it can.

The application also provides information about group calls using indicators provided in group call chat rooms (160). Here, the information about the group call may include the group call connection state of each member of the group call chat room. Here, the indicator provided in the group call chat room may be located in a predetermined area of the group call chat room interface (eg, the upper part of the group call chat room interface). In addition, the indicator according to another embodiment may be located in a part of the area corresponding to the group call chat room in the chat room list.

On the other hand, the application does not have to automatically enter the group call chat room corresponding to the group call by receiving the input of "join later" in the group call (170).

In this case, the user may later manually enter the group call chat room. For example, a group call chat room may be automatically added to the chat room list. More specifically, the application determines if a group call chat room is already in the chat room list, and if it determines that the group call chat room is not in the chat room list, then the group call chat. You may add the room to the chat room list. Therefore, the user may manually enter the group call chat room by selecting the group call chat room in the chat room list.

The application also provides an interface that allows you to join a group call when entering a group call chat room without having to re-receive the request signal for the group call (180). For example, the application may provide a rejoin button (or reconnect button) with an indicator provided in a group call chat room. If the user selects the rejoin button, the application may exchange the necessary information with the server to join an ongoing group call.

More specifically, the application may receive meta information about the group call chat room from the server without the user joining the group call. Here, the meta information about the group call chat room may include the request sender information and the request receiver information included in the request signal for the group call.

Therefore, if the application receives a request signal for a group call and the group call is started for the time being, the application allows the user to freely participate in the group call until before receiving the end signal of the group call from the server. Can be provided. As a reference, the server may send a group call termination signal based on the number of members participating in the group call. For example, the server may send a group call termination signal to all members of the group call chat room if the number of members participating in the group call is one.

Not only that, the meta information about the group call chat room may further include the group call connection status of each group call chat room member. Therefore, the application can provide a group call connection state for each member of the group call chat room regardless of whether or not they are participating in the group call.

That is, the application provides information as to whether each member of a group call is currently participating in the group call, not only when participating in the group call but also when not participating in the group call. To do.

Therefore, the user is provided with information about the members of the group call chat room to which he / she belongs and is currently making a group call, and can join or make a group call as long as the group call is in progress. You may quit.

Here, ending a group call is a concept that is distinguished from receiving a group call end signal from a server. For example, when ending a group call, the user can later rejoin the group call using the rejoin button, but when receiving a group call termination signal from the server, the user can rejoin the group call any further. It disappears.

The application may deactivate the group call related features provided in the group call chat room in response to receiving the termination signal. In this case as well, the group call chat room operates in the same manner as a normal instant message group chat room. That is, the user can start a new group call and join the newly started group call by transmitting a request signal for a new group call to the same member.

Also, a group call and a group call chat room are distinguished. For example, the application may provide group calls based on a group call chat room.

Not only that, joining a group call or ending a group call is distinguished from entering or leaving the group call chat room.

Entering a group call chat room literally involves entering a group call chat room that supports group call services. On the other hand, participating in a group call includes an operation of participating in a voice call (for example, a conference call) using mVoIP among a plurality of members.

Similarly, leaving a group call chat room literally involves leaving the group call chat room that supports the group call service. For example, when leaving a group call chat room, the application may switch from the group call chat room screen to the chat room list screen. On the other hand, ending a group call includes an operation of ending a voice call (for example, a conference call) using mVoIP between a plurality of members. As described above, when terminating a group call, any user whose group call is in progress by two or more members can rejoin the group call using the rejoin button.

Therefore, the user does not have to participate in the group call while entering the group call chat room.

Referring to FIG. 1B, a user who intends to start a group call according to an embodiment (hereinafter referred to as a request caller) uses a request signal for a group call by using an interface for transmitting a request signal for the group call. Is sent (191). In this case, the requesting caller's application displays a screen indicating that it is waiting to connect to at least one of the requested users of the group call (hereinafter referred to as the requesting receiver) (192). ..

The request receiver application provides an interface by receiving the request signal transmitted from the request originator to indicate whether or not to join the group call now (193). When the request recipient enters the input "Join now" in the group call using the interface, the request recipient's application automatically enters the group call chat room corresponding to the group call and enters the group call chat room. It receives the group call connection status of each member from the server and provides information about the group call using the indicator provided in the group call chat room (194).

On the other hand, when the request recipient inputs the input of "join later" in the group call using the interface, the request recipient application does not have to automatically enter the group call chat room. If the request recipient later manually enters the group call chat room, the request recipient's application can join the group call without having to rereceive the request signal for the group call (eg, rejoin). A button or reconnect button) is provided (195).

Here, the request recipient application displays who is currently participating in a group call using an indicator provided in the group call chat room, even when not participating in the group call.

If the request recipient selects the rejoin button, the request recipient's application may take action to join the group call. If the request occasional application successfully joins a group call, it provides information about the group call using the indicators provided in the group call chat room (195 194).

Also, if the user (request sender or request receiver) joins the group call and then ends the group call by selecting the end button, the application will request the request recipient's application to request for the group call. It provides an interface (eg, rejoin or reconnect button) that allows a group call to be joined without the need to rereceive the signal (194 195).

Therefore, in the application according to one embodiment, when a group call is started by using the above-described operation, the user can freely participate in the group call or make a group call before receiving the end signal of the group call from the server. Can provide technology that allows the termination of.

2A to 2C are diagrams for explaining an interface in which whether or not to participate in a group call is input in response to the reception of the request signal according to the embodiment.

Referring to FIG. 2A, the interface for inputting whether or not to join the group call according to the embodiment is the input button 220 for "join now" for the group call and "join later" for the group call. Includes input button 210.

Also, the interface in which whether or not to join the group call is input may further include information 230 about the member who transmitted the request signal for the group call. For example, an interface in which whether or not to join a group call is input may display the ID of the member who sent the request signal for the group call.

Further, the interface in which whether or not to join the group call is input may further include a predetermined message 240 corresponding to the request signal for the group call. For example, a predetermined message corresponding to a request signal for a group call may include "Let's make a group call ~".

Referring to FIG. 2B, the interface in which whether or not to join the group call according to another embodiment is input may further include a profile picture 250 of the member who transmitted the request signal for the group call. Therefore, the request receiver can more intuitively recognize the request sender.

Referring to FIG. 2C, the interface in which whether or not to participate in the group call according to the further embodiment is input may further include information 270 regarding the member to which the request signal for the group call is transmitted. Here, if the member to whom the request signal for the group call is transmitted has not yet joined the group call, the application may process the profile picture of the member thinly.

In addition, the interface in which whether or not to join the group call is input may further include the own group call connection state 280. For example, the application may display its group call connection status while waiting for a connection while waiting for the user to enter whether or not to join the group call.

3A to 3B are diagrams for explaining an indicator that provides information regarding a group call according to an embodiment.

Referring to FIG. 3A, the information about the group call according to one embodiment includes a group call connection state 310 for each member of the group call chat room and a profile picture 320 for each member of the group call chat room.

Here, the application adjusts the dimness of the profile picture according to the group call connection status. For example, the application may thin the profile picture of a member who is in a closed or connected state. In this case, the application may sharply process the profile picture of the member participating in the group call.

The information about the group call according to the other embodiment may further include at least one of the participation time 330 that participated in the group call, the network connection state 340 for the group call, or the member who requested the group call. .. The application may generate information about group calls based on the meta information received from the server.

Here, the participation time 330 of participating in the group call counts the time after oneself participates in the group call. When the group call is terminated and rejoined, the participation time 330 of participating in the group call may count the time after rejoining.

Also, the network connection status 340 for group calls may be displayed as a weather icon such as sun, clouds, or rain. For example, the application may display a sun icon when the network connection is good, a cloud icon when the network connection is normal, and a rain icon when the network connection is poor. In addition, the application may change the icon to play a notification sound to notify that the network connection status has changed if the network connection status changes during a group call.

In addition, the application may display the member who requested the group call by adding a predetermined graphic effect (for example, a crown icon) to the profile picture of the member.

An application according to a further embodiment uses an indicator provided in a group call chat room to activate at least one of a voice modulation function, a sound erasing function, or a speakerphone function, an interface 350, a group call. Further provided may be at least one of interface 360, or interface 370, which folds the indicator.

When the voice modulation function is activated, the application may modulate the user's voice by the activated voice modulation function and transmit it. In addition, when the sound erasing function is activated, the application prevents the user's voice from being transmitted to the other party. When the speakerphone function is activated, the other party's dialogue content can be heard by everyone around. The voice may be reproduced through the speaker.

The application may also provide an interface that allows the group call to be terminated and rejoined when receiving an input to terminate the group call.

The application may also reduce the indicator to display only information about group calls when receiving input that folds the indicator.

For example, referring to Figure 3B, the application participated in a group call connection status of each member of the group call chat room, profile picture of each member of the group call chat room, and group call by receiving the input to fold the indicator. An interface or group that displays only the participation time, network connection status for a group call, and the member who requested the group call, and activates at least one of the voice modulation function, the sound erasing function, or the speakerphone function. It is not necessary to display the interface for terminating the call and the interface for folding the indicator.

Here, the application may further provide an interface 380 that opens an indicator. When the application receives an input that opens the indicator, it again activates at least one of the voice modulation function, sound elimination function, or speakerphone function, an interface that ends a group call, and an interface that folds the indicator. Etc. may be displayed.

4A to 4B are diagrams for explaining an interface capable of participating in a group call without having to re-receive the request signal according to the embodiment.

Referring to FIG. 4A, an interface capable of joining a group call without having to re-receive the request signal according to one embodiment includes a rejoin button or a reconnect button 410.

In this case, the application may also provide information 420 about the group call, including the group call connection status, using the indicators provided in the group call chat room.

Referring to FIG. 4B, applications according to other embodiments further provide their own connection state 430 with indicators provided in a group call chat room.

FIG. 5 is a diagram for explaining an interface in which the presence / absence of confirmation of the request signal is input in response to the reception of the request signal according to the embodiment.

Referring to FIG. 5, the application according to one embodiment provides an interface in which the presence or absence of confirmation of a request signal is input in response to the reception of a request signal for a group call (510).

In this case, the application enters the group call chat room corresponding to the group call by receiving the input confirming the request signal. The application uses an indicator provided in the group call chat room to provide an interface for entering whether or not to join the group call now (520).

Since the items described with reference to FIGS. 1 to 4B are applied as they are to the subsequent operations of the application, a more detailed description will be omitted. That is, when receiving an input of "join now" in a group call, the application displays information about the group call, etc. (530). On the other hand, when receiving an input to "join later" in a group call, the application provides an interface that allows the group call to be joined without having to re-receive the request signal (540).

FIG. 6 is a diagram for explaining a predetermined message regarding the group call according to the embodiment.

Referring to FIG. 6, the application according to the embodiment inputs a predetermined message into the group call chat room corresponding to the group call by performing the operation related to the group call. Here, the application may display each message in the same or similar form (for example, balloon form) as when the user directly inputs the message.

For example, the application may enter the "Let's make a group call ~" message 610 into the group call chat room when sending a request signal for a group call. The application may also enter the "no response" message 620 into the group call chat room if there is no response from the request recipient.

If the application sends a request signal for a group call and then receives an input to cancel the group call before the group call begins, it may enter the message 630 "Cancel" into the group call chat room. .. In addition, the application may enter the "end" message 640 into the group call chat room if it receives input to end the group call after the group call has started. Here, the application may enter a message 650 in the group call chat room indicating the time of participation in the group call.

On the other hand, although not shown in the drawings, applications according to other embodiments may reproduce predetermined notifications corresponding to various cases that occur with respect to the group call. Here, the predetermined notification may include at least one of sound effects, bell sounds, vibrations, LED lamps, or graphic effects of the display.
