CLIENT AND OPERATING METHOD OF CLIENT [0002]

The following embodiments relate to a method of operation of a client and a client.

BACKGROUND ART [0002] In recent years, a wireless computing environment has emerged due to the development of technologies for terminals and wireless networks. As a result, the user of the terminal can communicate with the other party using the call application. Such a call application can not forward the other party's call request to a third party to a third party.

Embodiments may allow a third party to communicate with a counterpart client by processing a communication request of the counterpart client when the counterpart client has a communication request to communicate with the third party while the client and counterpart client are communicating with each other .

A method of operating a client according to a party comprises: communicating with a partner client; Acquiring location information of the other client through a predetermined process when there is a request from the other client for communication targeting another client; Setting a communication path with the another client based on the obtained location information; And transmitting the location information of the other client to the other client through the set communication path, wherein the other client establishes a communication path with the other client based on the location information of the other client.

The step of acquiring the location information of the other client through a predetermined process includes: transmitting a query for location information of the other client to the server; And receiving location information of the other client from the server.

The server may further receive the request from the client, and may transmit the location information of the client and the request to the other client.

When receiving the request, the other client may respond to the request based on the selection input of the user of the other client.

The server may send a rejection message for the request to the client if there is no response to the request within a predetermined time from the other client.

The method of operation of a client may include receiving a message indicating that a communication path is established between the other client and the other client from at least one of the other client and the other client, And releasing the communication path.

The communication path established between the client and the counterpart client and the communication path established between the client and the other client may correspond to a peer to peer (P2P) communication path.

A client according to one side for storing one or more commands; And communicating with a relative client based on the command; Acquiring location information of the other client through a predetermined process when there is a request from the other client for communication targeting another client; Setting a communication path with the another client based on the obtained location information; And transmitting the location information of the other client to the other client through the set communication path, wherein the other client sets a communication path with the relative client based on the location information of the other client do.

The step of acquiring the location information of the other client through a predetermined process includes: transmitting a query for location information of the other client to the server; And receiving location information of the other client from the server.

The server may further receive the request from the client, and may transmit the location information of the client and the request to the other client.

When receiving the request, the other client may respond to the request based on the selection input of the user of the other client.

The server may send a rejection message for the request to the client if there is no response to the request within a predetermined time from the other client.

Wherein when the controller receives a message indicating that a communication path has been established between the other client and the counterpart client from at least one of the other client and the counterpart client, Further releasing the path may be performed.

The communication path established between the client and the counterpart client and the communication path established between the client and the other client may correspond to a peer to peer (P2P) communication path.

Embodiments may allow a third party to communicate with a partner client by processing a communication request of the partner client when the client has a communication request to communicate with the third party while the client and the partner client are communicating with each other.

In the following description of the embodiments, a detailed description of related arts will be omitted if it is determined that the gist of the embodiments may be unnecessarily blurred.

1 is a diagram for explaining a call forwarding system according to an embodiment.

Referring to FIG. 1, the call forwarding system includes a server, a client A, a client B, and a client C.

Client A and Client B can communicate with each other. For example, client A and client B can send and receive data (e.g., voice packets and / or video packets) through a Peer To Peer (P2P) communication path. In other words, the user of client A and the user of client B can talk to each other.

Assume now that client A and client B are communicating with each other.

Client A requests Client B to communicate with Client C. In this case, the client B receives (110) a request for communication from the client A to the client C as the target (or the other party). In other words, the client B can receive a communication request, i.e., a communication request (target = client C) from the client A, indicating that the client A wants to communicate with the client C.

When the client B receives the communication request (target = client C) of the client A, it sends a query to the server about the location information of the client C (for example, the network address information of the client C) C (111).

When the server receives the query about the location information of the client C from the client B, it transmits the location information of the client C to the client B (112).

When the server receives a communication request (target = client C) of the client A from the client B, the server transmits the communication request (target = client C) and the location information of the client B to the client C (113). In other words, the server can inform client C that client A wants to communicate with client C. In addition, the server can transmit the location information of the client B to the client C so that the client C establishes the P2P communication path with the client B.

Client C sends an acknowledgment to client A's communication request (target = client C) to the server (114). In other words, the client C can respond to the client A's communication request. Depending on the implementation, the server may send an acknowledgment of client C to client B. That is, the client B can receive the acknowledgment of the client C from the server. In other words, client B knows by receiving an acknowledgment that client C desires to communicate with client A. Further, according to the implementation, if the server does not acknowledge the communication request (target = client C) of the client A within a predetermined time from the client C, the server transmits a reject message (target = client C) To the client B. < RTI ID = 0.0 > Client B may send a reject message to Client A.

Since the client B has received the location information of the client C from the server, the client B can establish a P2P communication path with the client C (115). For example, the client B can transmit a P2P communication connection request to the client C using the location information of the client C. The client C can determine that the client that transmitted the P2P communication connection request is the client B by comparing the location information received from the server with the sender location information included in the P2P communication connection request. Client C may send an acknowledgment for the P2P communication connection request to Client B. Thus, the client B can establish a P2P communication path with the client C.

When the P2P communication path with the client C is established, the client B transmits the location information of the client A to the client C (117). In addition, the client B transmits the location information of the client C to the client A (116).

Since the client A has received the location information of the client C from the client B, it can establish the P2P communication path with the client C (118). For example, the client A can transmit a P2P communication connection request to the client C using the location information of the client C. The client C can determine that the client that transmitted the P2P communication connection request is the client A by comparing the location information received from the client B with the sender location information included in the P2P communication connection request. Client C may send an acknowledgment for the P2P communication connection request to Client A. As a result, the client A can establish a P2P communication path with the client C.

Client A and client C can send and receive data (e.g., voice packets and / or video packets) over the P2P communication path. In other words, the user of client A and the user of client C can talk.

Although not shown in FIG. 1, when the P2P communication path is established between the client A and the client C, the client B releases the communication path between the client B itself and the client A and the communication path between the client B itself and the client C )can do. According to the implementation, the client B can maintain the communication path between the client B itself and the client A and the communication path between the client B itself and the client C. In this case, the client C participates in the communication between the client A and the client B, so that multi-party communication or a conference call can be performed.

2 is a flowchart for explaining an example of the operation of the call forwarding system according to one embodiment.

Referring to FIG. 2, the client A transmits a communication request (target = client B) to the server (210). In other words, the client A can request the server to communicate with the client B as a target.

The server transmits the communication request (target = client B) of the client A and the location information of the client A to the client B (211). In addition, the server transmits the location information of the client B to the client A (212).

The client B transmits an acknowledgment to the communication request (target = client B) of the client A to the server (213). In other words, client B responds to client A's communication request (target = client B). Depending on the implementation, the server may send an acknowledgment of client B to client A.

Client A establishes a communication path (e. G., P2P communication path) with client B (214).

Client A and client B send and receive data through a communication path.

When an event occurs for the communication request (target = client C), client A sends a communication request (target = client C) to client B (215). For example, when the user Paul of the client A wants to talk to the user Alex of the client C while talking with the user Tadd of the client B, the user Paul can select the partner adding button exposed on the call screen of the client A, You can select Alex from the list displayed by selection. By selecting Alex in the list, an event for the communication request (target = client C) can occur at client A, and client A can request client B to communicate with client C as a target.

If there is a communication request (target = client C) of the client A, the client B requests the location information of the client C to the server (216). Also, although not shown in FIG. 2, the client B can transmit a communication request (target = client C) of the client A to the server.

The server transmits the location information of the client C to the client B according to the request for the location information of the client C (217). In addition, the server transmits the location information of the client B and the communication request (target = client C) of the client A to the client C (218).

Client C sends an acknowledgment to client A's communication request (target = client C) to the server (219). In other words, the client C can respond to the communication request (target = client C) of the client A to the server. Although not shown in FIG. 2, the server may send an acknowledgment of the client C to the client B. In this case, the client B can know that the client C has accepted the communication request of the client A (target = client C).

If the communication request of client A (target = client C) has been accepted by client C, client B and client C establish a communication path (e.g., P2P communication path) (220).

The client B transmits the location information of the client C to the client A through the communication path (221). In addition, the client B transmits the location information of the client A to the client C (222).

When the client A receives the location information of the client C, the client A establishes a communication path (for example, P2P communication path) with the client C (223).

The client B can release the communication path established between the client B itself and the client C (224) and release the communication path established between the client B itself and the client A (225). For example, when the client B receives a message indicating that the communication path is established between the client A and the client C from at least one of the client A and the client C, the communication path set between the client B and the client C and the client B And the client A can be released.

3 is a view for explaining another example of the operation of the call forwarding system according to the embodiment.

Referring to FIG. 3, client A and client B communicate through a communication path (310). At this time, a request event for communication targeting Client C in Client B may occur (311). Unlike the example described with reference to FIGS. 1 and 2, an event for a communication request (target = client C) may occur in the client B. For example, user Paul at client A may request Tadd to talk to user Alex at client C while talking with user Tadd at client B. [ In this case, Tadd can select the partner addition button exposed on the call screen of the client B and select Alex from the list displayed by the selection of the partner addition button. By selecting Alex in the list, an event for the communication request (target = client C) in client B can occur.

When an event for the communication request (target = client C) occurs, the client B requests the location information of the client C to the server (312). Although not shown in FIG. 3, client B may send a communication request (target = client C) to the server.

The server transmits the location information of the client C to the client B (313). In addition, the server transmits the location information of the client B and the communication request (target = client C) to the client C (314).

Client C sends an acknowledgment to client A's communication request (target = client C) to the server (315).

The client B sets a communication path (for example, a P2P communication path) with the client C using the location information of the client C (316).

The client B transmits the location information of the client C to the client A (317). In addition, the client B transmits the location information of the client A to the client C (318).

When receiving the location information of the client C from the client B, the client A sets a communication path with the client B (319). Thereby, the user Paul of the client A can talk with the user Alex of the client C. Also, the user Paul of the client A can talk to Alex by asking the user Tadd of the client B not to know the telephone number of the user Alex of the client C but wants to talk with Alex.

When a communication path is established between the client A and the client C, the client B can release the communication path established between the client B itself and the client C (320) and release the communication path established between the client B itself and the client A (321).

4 is a view for explaining the operation of the client A of the call forwarding system according to the embodiment.

Referring to the call screen 410 of FIG. 4, the user Paul of the client A is currently in communication with the user Tadd of the client B. In other words, the calling party on the call screen 410 is Tadd.

Paul may want to talk to user Alex on client C during a call with Tadd. In this case, Paul can select the counterpart add button 411 exposed on the call screen. The list can be displayed by Paul selecting the counterpart add button 411, and Paul can select Alex from the list. If Alex is selected in the list, client A can send a call request (target = client C) to client B. At this time, the call connection screen 420 may be displayed on the display of the client A. For example, a message 420 "Calling Alex" may be displayed on the client A's display.

Client B can process the call request (target = client C) of client A instead of client A. The operation of the client B has been described with reference to FIG. 1 to FIG. 3, and a detailed description thereof will be omitted.

Client A can establish a communication path with client C. This allows Paul to speak with Alex. A call screen 430 of client A is shown. On the call screen 430, the current communication party is Alex.

If a communication path is established between client A and client C, the communication path between client A and client B can be released.

5 is a view for explaining the operation of the client B of the call forwarding system according to the embodiment.

Referring to the call screen 510 of FIG. 5, the user Tadd of the client B is currently in communication with the user Paul of the client A. In other words, the calling party on the call screen 510 is Paul.

Paul may want to talk to Alex during a call with Tadd. In this case, the client B can receive the call request (target = client C) from the client A.

Upon receiving the call request (target = client C), the client B transmits a query and a call request (target = client C) for the location information of the client C to the server, and receives the location information of the client C from the server. At this time, the call forwarding screen 520 may be displayed on the display of the client B. For example, a message 521 of "Paul's phone is being delivered to Alex" may be displayed on the client B's display.

The client B establishes a communication path with the client C using the location information of the client C. The client B transmits the location information of the client A to the client C. In addition, the client B transmits the location information of the client C to the client A.

When a communication path is established between the client A and the client C, the client B can release the communication path between itself and the client A and the communication path between itself and the client C. At this time, a call end screen 530 may be displayed on the display of the client B. For example, a message 531 of "End all calls" may be displayed on the display of client B.

6 to 7 are views for explaining the operation of the client C of the call forwarding system according to the embodiment.

The client C receives the call request (target = client C) of the client A and the location information of the client B from the server. At this time, a call request screen 610 for a call request (target = client C) of the client A may be displayed on the display of the client C. For example, as in the example shown in Figure 6, the message "611" tells Paul that Paul is calling instead of talking to Tadd if he / she wants to answer Paul's call. May be displayed.

Let the user Alex of client C choose "Yes". At this time, client C sends an acknowledgment to client A's call request (target = client C) to the server.

After sending an acknowledgment to the server, client C can establish a communication path with client B. At this time, the call connection screen 620 may be displayed on the display of the client C. The user Alex of the client C can talk to the user Tadd of the client B by selecting the "Yes" button (not shown) displayed on the call connection screen 620. At this time, the client C can display the call screen 710 and can receive the location information of the client A from the client B via the communication path.

When receiving the location information of the client A, the client C can output a message "Would you like to talk with Paul?" To the call screen 710.

If the user Alex of the client C selects "YES ", the client C can establish a communication path with the client A. At this time, the call connection screen 720 may be displayed on the display of the client C.

When a communication path is established between the client A and the client C, the user Paul of the client A can talk with the user Alex of the client C.

8 is a flowchart illustrating a method of operating a client according to an embodiment.

Referring to FIG. 8, a client communicates with a relative client (810). For example, a client can send and receive data through a peer-to-peer communication path with a peer client. Here, the client may correspond to the client B described with reference to FIGS. 1 to 7, and the other client may correspond to the client A described with reference to FIG. 1 to FIG.

If there is a request for communication targeting another client from the other client, the client obtains the location information of the other client through a predetermined process (820). For example, if there is a request for communication targeting another client, the client may send a query to the server about location information of another client and may receive location information of another client from the server. Here, the other client may correspond to the client C described with reference to FIG. 1 through FIG.

The client sets a communication path with another client based on the acquired location information (830).

The client transmits the location information of the other client to the other client through the established communication path (840). In addition, the client transmits location information of another client to the other client. Thus, another client can know the location information of the other client, and the other client can know the location information of the other client. Accordingly, the other client and the relative client can set the communication path.
