A method for managing transmitted messages in a messenger server and a computer-readable recording medium

An embodiment of the present invention relates to a method for managing a transmitted message in a messenger server for managing a message transmitted from a messenger service connected to multiple devices, and a computer-readable recording medium.

Recently, users who need various kinds of communication communicate through homepage, e-mail, and phone. There is this.

On the other hand, as a useful method for real-time transmission of information using the Internet, there is an instant messenger (Instant Messenger). The purpose of instant messengers is to deliver simple messages between users in real time. The instant messenger can talk in real time through a text message transmitted as if two users were directly communicating. This is because the instant messenger itself places importance on the real-time nature of the messenger and immediately delivers the inputted information.

As the messenger service expands from the existing PC-based messenger and SMS (Short Message Service) service to the IP (Internet Protocol)-based mobile messenger, various mobile messengers are being offered competitively. In addition, a user terminal (eg, a mobile device) is personalized, and as the number of cases where a user uses several devices at the same time increases, services for multiple devices are also provided.

For example, when one user simultaneously uses two or more user terminals, one messenger service may be simultaneously used through several user terminals. In this case, although the same user is recognized by the chatting partner of the messenger service, the messenger service may be actually provided to the same user through a plurality of user terminals.

When using a mobile messenger in such a multi-device environment, when a conversation partner sends a message, the message is delivered to all user terminals it owns, and alarms, vibrations, and pop-ups are provided accordingly. In the above situation, the user tries to transmit and receive a message in one user terminal, but since the message is continuously received in the other user terminals, an alarm or vibration may sound or a pop-up message may be generated, which may cause inconvenience. In addition, battery consumption is additionally generated due to the unsolicited message reception notification, thereby affecting the basic performance of the user terminal.

In addition, when a message is transmitted from a user terminal currently in use, synchronization is not performed in real time with another user terminal connected to a multi-device, so there is an inconvenience of periodically performing a polling procedure.

In order to solve this problem, an embodiment of the present invention distinguishes a user terminal currently being used by a user from a user terminal not in use, thereby providing a message reception notification only to the user terminal being used. A management method and a computer-readable recording medium may be provided.

In addition, another embodiment of the present invention distinguishes a user terminal currently used by a user from a user terminal not in use in a messenger server that can provide real-time synchronization for message confirmation processing for a plurality of user terminals. It is possible to provide a transmission message management method and a computer-readable recording medium.

According to an embodiment of the present invention, a method for managing a transmission message in a messenger server includes: receiving a transmission message from a first user terminal from among a plurality of user terminals connected to a first user account; identifying at least one other user terminal excluding the first user terminal from among a plurality of user terminals connected to the first user account; and transmitting the received transmission message to the confirmed at least one other user terminal.

Further, according to another embodiment of the present invention, a method for managing a message transmitted in a messenger server is a method for transmitting a message between a plurality of user terminals connected to a first user account and a user terminal connected to a second user account, the method comprising: receiving a transmission message from a second user terminal connected to a second user account to the first user account; adding information indicating an inactive state to the received transmission message; and transmitting a transmission message to which information indicating the inactive state is added to a user terminal set to the inactive state from among a plurality of user terminals connected to the first user account.

Further, according to another embodiment of the present invention, a method for managing a message transmitted in a messenger server is a method for transmitting a message between a plurality of user terminals connected to a first user account and a user terminal connected to a second user account, the method comprising: receiving a transmission message from a second user terminal connected to a second user account to the first user account; transmitting the received transmission message to a plurality of user terminals connected to the first user account; receiving information indicating confirmation of the transmission message from a first user terminal among a plurality of user terminals connected to the first user account; and transmitting information indicating confirmation of a transmission message to at least one other user terminal other than the first user terminal among a plurality of user terminals connected to the first user account.

Meanwhile, information on a method of managing a transmission message in the messenger service may be stored in a computer-readable recording medium. These recording media include all kinds of recording media in which programs and data are stored so that they can be read by a computer system. Examples include ROM (Read Only Memory), RAM (Random Access Memory), CD (Compact Disk), DVD (Digital Video Disk)-ROM, magnetic tape, floppy disk, optical data storage device, embedded multimedia card (eMMC) and the like, and also includes those implemented in the form of a carrier wave (eg, transmission through the Internet). In addition, such a recording medium is distributed in a computer system connected to a network, so that computer-readable codes can be stored and executed in a distributed manner.

According to an embodiment of the present invention, efficiency of messenger service use can be improved by dynamically managing connections of user terminals currently used by a user in a multi-device messenger service environment in which the same user uses a messenger service through a plurality of user terminals. increase and reduce battery consumption.

In addition, according to an embodiment of the present invention, it is possible to provide real-time message synchronization for a plurality of user terminals while optimizing battery consumption for messages sent by the user from a plurality of user terminals used by the user.

In addition, according to an embodiment of the present invention, it is possible to increase usability in a multi-device messenger service environment by minimizing notification of message reception except for the user terminal currently used by the user among a plurality of user terminals used by the same user. .

In addition, according to an embodiment of the present invention, message reception notification may not be unnecessarily notified to a plurality of user terminals used by the same user, and message confirmation processing may be synchronized in real time.

According to embodiments of the present invention, in a multi-device messenger service environment in which one user uses a messenger service through a plurality of user terminals, the currently used user Disclosed are an apparatus and method for managing transmitted messages in a messenger service capable of providing a message reception notification only to a terminal.

In addition, other embodiments of the present invention distinguish a user terminal currently used by a user from a user terminal not in use in a messenger service that can provide real-time synchronization for message confirmation processing for a plurality of user terminals. Disclosed are an apparatus and method for managing transmitted messages.

Meanwhile, in embodiments of the present invention to be described later, 'active connection' and 'inactive connection' in order to distinguish between a terminal currently used by a user and a user terminal not in use among a plurality of user terminals. )' is used. However, embodiments of the present invention are not limited to the specific terms, and the terms are used to help understanding of the embodiments of the present invention.

In addition, the active connection can be managed in a chat room (or chat room) unit, and may mean the connection state of the server/client that most recently communicated with the server while the user terminal (client) and the messenger server are TCP-connected. .

Accordingly, according to an embodiment of the present invention, the messenger server may include the flags (Active, Inactive) indicating 'active' or 'inactive' in the message to be transmitted. In this case, the method of transmitting the flag may be transmitted by being included in a message of an existing protocol or transmitted by being included in a new message.

The 'active' state may mean that it operates in the same manner as a general message transmission method, and it may be implemented to transmit a message only to a user terminal in an active connection state among a plurality of connected user terminals according to the state information. Also, when there is no user terminal in an active state among a plurality of user terminals being accessed, all user terminals being accessed may be regarded as an active connection state and message transmission may be processed.

The 'inactive' state is not an 'active' state but user terminals, and may perform a separate message transmission process according to an embodiment of the present invention. For example, when a message is transmitted to a user terminal in an 'inactive' state, the message reception notification function may not operate according to an embodiment of the present invention.

Meanwhile, when a messenger application in all user terminals among a plurality of user terminals being accessed by a specific user is not connected to a messenger server, a message may be transmitted in an 'active' state to all user terminals. In this case, when all user terminals receive a message including the 'active' status flag, a message reception notification such as alarm/vibration/pop-up may occur.

In addition, according to an embodiment of the present invention, the transition condition to the 'active' state may be implemented in various ways. For example, when a user views the entire content of a received message or sends a message to a conversation partner in one device, the 'active' state may be determined to start from this point because it is connected to the messenger server. In this case, the remaining user terminals may transmit messages by setting them to an 'inactive' state. In addition, the user is not viewing the chat room in the 'active' state. That is, when the screen is turned OFF or moved to another screen, a timer for a preset time (eg, 5 minutes) is generated for the user terminal and automatically switches to the 'inactive' state when the set time elapses It can be handled as much as possible. Also, the user terminal may process to switch to the 'inactive' state when it receives a 'disconnect request message' from the messenger server or when there is no response from the user terminal. The 'connection termination request message' transmitted from the messenger server may be transmitted to the corresponding user terminal when there is no transmission message for a preset time in the active state.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to enable those of ordinary skill in the art to easily practice the present invention.

Accordingly, when a conversation channel between the first user terminal 100a and the second user terminal 100b is created, a message transmitted from each user terminal is transmitted to the corresponding user terminal through the messenger server 102 .

In this case, according to an embodiment of the present invention, user A may use a messenger service using a _{plurality of user terminals, for example, user terminal A1 ( 100a 1} ) and user terminal A2 ( 100a _{2 ).} Accordingly, when the user A _{transmits a message to the user terminal B 100b of the user B through the user terminal A1 100a 1} , the transmitted message is transmitted to the messenger server 102 through the communication network 101 . and the messenger server 102 transmits the message back to the user terminal B 100b through the communication network 101 . On the other hand, when the user terminal B 100b is not connected to the messenger server (eg, TCP (Transmission Control Protocol) connection), the message is pushed to the user terminal B 100b through the push server 103 . It can be sent as a message.

In addition, since the user terminal A1 ( 100a ₁ ) and the user terminal A2 ( 100a ₂ ) are simultaneously connected as a multi-device _{as shown in FIG. 1 , the user terminal A1 ( 100a 1} ) in the user terminal B ( The message transmitted to 100b) may also be transmitted to the user terminal A2 ( 100a ₂ ). As described above, a message for transmitting a transmission message of the same user to another user terminal of the same user will be referred to as a mirror message in embodiments of the present invention.

At this time, according to an embodiment of the present invention, when the user terminal A2 ( 100a ₂ ) is in an unused state (eg, in the embodiments of the present invention, it is referred to as an 'Inactive' state), in the user terminal A2 ( 100a ₂ ) Message reception notification (eg, alarm, vibration, pop-up message, etc.) may be implemented so as not to be notified. For example, an identifier indicating an 'Inactive' state is added to a message transmitted to the user terminal A2 (100a ₂ ), and when a message to which the identifier is added is received, the message reception notification mode is 'off' and received It can be implemented to disable the notification function for messages.

Meanwhile, according to another embodiment of the present invention, when the user B transmits a message to the user A through the user terminal B 100b, the transmitted message is transmitted to the messenger server 102 through the communication network 101, The messenger server 102 transmits the message back to the user terminal A 100a through the communication network 101 . In this case, when the user A is in a multi-device situation in which the messenger service is simultaneously accessed through a plurality of user terminals, the transmitted message may be transmitted to the user terminal A1 ( 100a ₁ ) and the user terminal A2 ( 100a ₂ ) at the same time. .

Meanwhile, according to an embodiment of the present invention, the user terminal A1 ( 100a ₁ ) is in a state used by the user (eg, in the 'Active' state in the embodiments of the present invention), and the user terminal A2 ( 100a ₂ ) is used by the user. When it is not in a state (eg, in the 'Inactive' state in the embodiments of the present invention _{), a message is transmitted to the user terminal A1 ( 100a 1} ) through the messenger server 102 , and the user terminal A2 ( 100a ₂ ) Rho may allow a message to be transmitted in the form of a push message through the push server 103 . At this time, not to so present in accordance with an embodiment of the invention that is not used by the user terminal A2 (100a ₂₎ state, the user terminal A2 (100a _2), the message reception notification (e.g., an alarm, a vibration, a pop-up message, etc.) can also be implemented. For example, an identifier indicating an 'Inactive' state is added to a message transmitted to the user terminal A2 (100a ₂ ), and when a message to which the identifier is added is received, the message reception notification mode is 'off' and received It can be implemented to disable the notification function for messages.

In addition, the communication network 101 may be a well-known World Wide Web (WWW), and may use a wireless transmission technology used for short-range communication such as Infrared Data Association (IrDA) or Bluetooth (Bluetooth). may be

2 is a block diagram illustrating a detailed structure of a messenger server according to an embodiment of the present invention. Referring to FIG. 2 , the messenger server 102 according to an embodiment of the present invention may include a message transmission processing unit 210 , a user connection management unit 220 , and a terminal state determining unit 230 . Also, the messenger server 102 may further include at least one database such as a message information database 240 and a connection information database 250 . Meanwhile, each of the databases may be constructed by being included in the messenger server 102 or may be constructed as a separate database server.

The message transmission processing unit 210 may perform a function of receiving a message requested to be transmitted from each user terminal 100 to the conversation partner, and transmitting the message to the corresponding conversation partner's user terminal 100 . In this case, the message transmitted between the user terminals 100 may be stored in the message information database 240 .

The user connection management unit 220 may check the user's messenger service connection state and perform a function of managing the message transmission processing unit 210 to transmit different messages according to the user's connection state. In this case, information on the connection state may be confirmed through the connection information database 250 .

Meanwhile, according to an embodiment of the present invention, when a single user accesses a messenger service using a plurality of user terminals in a multi-device situation, the messenger transmission processing unit 210 transmits a message to be transmitted to a plurality of users as described above. The transmission may be processed to a terminal (eg, to a user terminal of the receiver and another user terminal of the sender, or to a plurality of user terminals of the receiver).

At this time, the user access management unit 220 checks the connection state (eg, 'active' state or 'inactive' state) to other user terminals of the sender or the plurality of user terminals of the receiver, and the present invention According to an embodiment of , a message may be transmitted and processed differently for each connection state.

For example, when the user terminal to receive the message is in an active state, the message transmission processing unit 210 may transmit the message including the active state information or transmit the message without additional additional state information. Also, when the user terminal to receive the message is in the inactive state, the message transmission processing unit 210 may transmit the message including the inactive state information.

On the other hand, each user terminal 100 that has received the message including the status information according to an embodiment of the present invention checks the status information included in the received message, and when the status information is inactive, the embodiment of the present invention The message reception notification function can be turned off according to the Accordingly, when the user receives a message from the user terminal 100 that is not currently being used, the message reception notification function is turned off according to the inactive state information, and a separate message reception notification is not performed, thereby providing unnecessary message notification. It does not, and it can optimize battery consumption.

When the same user accesses using a plurality of user terminals, the terminal state determination unit 230 determines whether the user is currently using the corresponding user terminal and obtains the access state information of the corresponding user terminal stored in the access information database 250 . Perform the update function. For example, in FIG. 1 , in a state in which user A accesses the messenger service through a plurality of user terminals (eg, user terminal A1 ( 100a ₁ ) and user terminal A2 ( 100a _{2 )), using user terminal A1 ( 100a 1} ) When the message is transmitted, the terminal state determination unit 230 may determine the user terminal A1 ( 100a ₁ ) as an 'active' state, and determine the user terminal A2 ( 100a ₂ ) as an 'inactive' state. . Accordingly, in the connection information database 250, as shown in FIG. 3 , _{the connection states of the user terminal A1 ( 100a 1} ) and the user terminal A2 ( 100a ₂ ) may be stored as 'active' and 'inactive', respectively. have.

Meanwhile, in an embodiment of the present invention, each functional unit and module may mean a functional and structural combination of hardware for performing the technical idea of the embodiment of the present invention and software for driving the hardware. For example, each functional unit may mean a predetermined code and a logical unit of a hardware resource for executing the predetermined code, and does not necessarily mean physically connected code or one type of hardware. It can be easily inferred to an average expert in the technical field of the embodiment of the invention.

3 is a diagram illustrating a connection state management table for a multi-device according to an embodiment of the present invention. Referring to FIG. 3 , the access information database 250 may store access state information of user terminals accessed by each user. In addition, the access information database 250 may further include and store recent message transmission time information.

For example, when the user A _{accesses the messenger service through the user terminal A1 ( 100a 1} ) and the user terminal A2 ( 100a ₂ ), according to an embodiment of the present invention, the user A currently used by the user A is determined and each user terminal can store connection status information of For example, as shown in FIG. 3 , the user terminal A1 100a ₁ may be stored in an 'active' state, and the user terminal A2 100a ₂ may be stored in an 'inactive' state.

In this way, by storing and managing the connection state information according to whether each user terminal is currently used, when a specific user accesses a plurality of user terminals, the message reception notification function can be implemented so that the currently unused user terminal does not operate.

In addition, as shown in FIG. 3, by storing the latest message transmission time for each user terminal, when a specific user terminal does not transmit a message for more than a preset time (T) in the 'active' state, it automatically returns to the 'inactive' state. It can also be implemented to be converted.

Meanwhile, according to another embodiment of the present invention, the determination of the 'active' state and the 'inactive' state as described above may be determined as the current connection state between the messenger server and the user terminal without using information stored in the database. . For example, when the user's message is transmitted, the messenger server may determine the state of the corresponding user terminal as 'active' or 'inactive' based on whether each user terminal and the messenger server are connected (eg, whether there is a TCP connection).

4 is a diagram illustrating a transmission message management procedure in a messenger service according to an embodiment of the present invention. Referring to FIG. 4 , a user A may _{access the messenger server 102 through a user terminal A1 ( 100a 1} ) and a user terminal A2 ( 100a ₂ ) to transmit/receive a message to/from the user terminal B ( 100b ). In this way, unnecessary message reception notification can be prevented by managing the status information of each user terminal according to an embodiment of the present invention in a multi-device situation.

More specifically, as shown in FIG. 4 , the user A has a conversation with the user terminal B 100b while connected to the messenger server 102 _{through the user terminal A1 ( 100a 1} ) and the user terminal A2 ( 100a _{2 ).} In this case, the message transmitted from the user terminal B ( 100b ) to the user A may be transmitted to the user terminal A1 ( 100a ₁ ) and the user terminal A2 ( 100a ₂ ), respectively.

For example, when the user terminal B 100b inputs the message “Hello” through the message input window of the messenger application and requests transmission of the message from user A, the message “Hello” requested to be transmitted is transmitted to the messenger server 102 and the push server. It may be transmitted (402, 404, 406, 408) to the user terminal A1 (100a ₁ ) and the user terminal A2 (100a _{2) through (103).} Upon receiving a message from the user terminal B 100b, the user A may transmit the message to the user terminal B 100b through the user terminal _{A1 100a 1 .} For example, when the user terminal A1 ( 100a ₁ ) inputs the message “Hi” through the message input window of the messenger application to request transmission from the user B, the message “Hi” requested to be transmitted is transmitted through the messenger server 102 . It may be transmitted (410, 412) to the user terminal B (100b).

In this case, the messenger server 102 may transmit ( 414 , 416 ) _{a message requested to be transmitted from the user terminal A1 ( 100a 1} ) to the user terminal A2 ( 100a _{2 ) in order to synchronize the transmitted and received messages.} As described above, a message transmitted to another user terminal of the same user may be referred to as a mirror message. On the other hand, the mirror message transmitted to the user terminal A2 (100a ₂₎ may be sent on the push server 103 to the user terminal A2 (100a _2). In this case, the user terminal A2 ( 100a ₂ ) may not notify the reception of the message in response to the reception of the mirror message according to an embodiment of the present invention. For example, the user terminal A2 ( 100a ₂ ) can confirm that the message is transmitted from another user terminal (ie, user terminal A1 ( 100a ₁ )) of the same user by checking the sender of the received message “Hi”. According to the confirmation, in the case of a message transmitted from the same user (ie, a mirror message), according to an embodiment of the present invention, the currently set message reception notification function is turned off, or the message reception notification function is temporarily not operated. By doing so, you can prevent unnecessary message reception notifications from occurring.

In addition, in the messenger server 102, in the multi-device state in which the user A is connected to a plurality of user terminals (eg, the user terminal A1 ( 100a ₁ ) and the user terminal A2 ( 100a ₂ )), the user terminal A1 ( 100a ) _Since the message transmission request has been received through _{1 ), the user terminal A1 ( 100a 1} ) may be determined to be in an 'active' state. Also, according to an embodiment of the present invention, the other user terminals of the user A (ie, user terminal A2 100a ₂ ) may be determined to be in an 'inactive' state.

Next, when the user terminal B 100b requests to transmit the message "Please, ..." to the user A, the messenger server 102 sends the user terminal A1 ( 100a ₁ ) and the user terminal A2 which are the access terminals of the user A The message requested to be transmitted may be transmitted to (100a _{2 ).} In this case, the user terminal A1 (100a ₁₎ the "active" state because it is said in the user terminal A1 (100a ₁₎ is normally a message is sent (418, 420), the messenger chat window of the user terminal A1 (100a ₁₎ the The message sent, "Please, ..." may be displayed.

On the other hand, since the user terminal A2 ( 100a ₂ ) is in an 'inactive' state, the messenger server 102 adds 'inactive' state information to the message to be transmitted according to an embodiment of the present invention, thereby adding the user terminal A2 ( 100a _{2 ) to the user terminal A2 ( 100a 2 ).} ) is sent to In this case, the message transmitted to the user terminal A2 ( 100a ₂ ) may be transmitted ( 422 , 424 ) through the push server 103 . The user terminal A2 ( 100a ₂ ) checks 'inactive' status information included in the transmitted message, switches the message reception notification function to an off state, or temporarily disables the message reception notification function. The reception notification of the message "Please, ..." may not be provided _{by the user terminal A2 ( 100a 2 ).}

On the other hand, information on the time when the message is transmitted from the user terminal A1 ( 100a ₁ ) may be stored in the database as shown in FIG. 3 , and a preset time (T) is obtained by operating a timer from the time at which the message is transmitted. When elapsed, the connection state of the user terminal A1 ( 100a ₁ ) may be implemented to automatically switch from an 'active' state to an 'inactive' state.

In this way, the user A who has transmitted the message to the user terminal A1 ( 100a ₁ ) may then transmit the message using the _{user terminal A2 ( 100a 2 ).} For example, when the user A requests 426 to transmit the message “Sorry, I change ...” to the user B 100b using the _{user terminal A2 100a 2 , the messenger server 102 transmits the message} According to the request, the message "Sorry, I change ..." is transmitted (428) to the user terminal B (100b) and processed.

At this time, as described above, the messenger server 102 confirms that the user A is a user who has accessed through a multi-device according to a message transmission request from _{the user terminal A2 ( 100a 2 ), and confirms that the user A is a user connected to another user terminal (eg,} , a mirror message may be transmitted to the user terminal A1 ( 100a _{1 ).} Accordingly, the messenger server 102 may transmit the message "Sorry, I change ..." to the user terminal A1 100a ₁ through the push server 103 (430, 432).

On the other hand, it is possible to change the user terminal A2 (100a ₂₎ to "active" based on the message transmission request from the the messenger server 102, the user terminal A2 (100a _2), in accordance with an embodiment of the present invention. Accordingly, the user terminal A1 ( 100a ₁ ) may change to an 'inactive' state.

Upon receiving the message "Sorry, I change ..." through the push server 103, the user terminal A1 (100a ₁ ) checks the sender of the transmitted message to confirm that it is a mirror message, and as described above, According to an embodiment of the present invention, it may be implemented so that the message reception notification function does not operate.

Next, when the user terminal B 100b requests to transmit the message "OK" to the user A, the messenger server 102 connects the user terminal A1 (100a ₁ ) and the user terminal A2 (100a ₂ ), which are the access terminals of the user A (100a 2 ). to transmit the message requested to be transmitted.
