Description

ONLINE SITE MANAGEMENT SERVER AND CONTROL METHOD THEREOF}

The present invention relates to an online site management server and a control method thereof, and more particularly, to an online site management server for registering and managing a non-site member in a predetermined group included in a site and a control method thereof.

In recent years, with the construction of networks and the development of electronic communication technology, the Internet has been activated, and many people have used functions provided by the servers by joining as members on servers on the Internet.

In addition to a web server providing a web page, a server on the Internet includes a server that enables communication such as a messenger, for example.

By the way, each server on the Internet manages a predetermined site to receive members, and generates a predetermined group at the request of the subscribed members so that exchange (message transmission and reception, etc.) between members belonging to each group is performed.

For example, a plurality of groups may be created in one site, and members who join the site may further register with the created group and receive a message transmitted in each group.

One such type is a cafe run by naver.com of NHN. That is, members of naver.com may create a cafe corresponding to a new group, or join a pre-created cafe to be active in the cafe.

As such, groups can be created on any one site, and in the related art, members of the site need to visit the group first to join a specific group.

In addition, each group may include only members who have joined the site, for example, people who do not join the site for personal reasons are not able to join the group.

Furthermore, a certain group member belonging to each group may want to send an announcement to all group members or some group members belonging to the group. For example, e-mail or text message, etc.) was unified, which was disadvantageous.

The present invention has been made to solve the above-mentioned disadvantages, the purpose is to allow non-site members to register as members of the group of the site, and to determine the optimal notification method according to the status of each group member In addition, the present invention provides an online site management server and a control method thereof so that each site member can easily check the group to which the member is joined.

In order to achieve the above object, a method of controlling an online site management server for performing an online site operation according to the present invention includes creating a group at the request of a predetermined user who has subscribed to the site, and joining the site. Registering at least one of a site member and a non-site member not joined to the site as a member of the created group ("Group Member"); Selecting at least some of the group members as notification targets for transmitting predetermined notification contents according to a request of a predetermined member of the created group; Determining whether there is a group member currently logged in to the site among the selected notification targets; As a result of the determination, if there is a logged-in group member, the logged-in group member transmits the notification contents through a communication channel connected by log-in, and the group which has subscribed to the site but is not currently logged in among the selected notification targets. For the member and the non-site member not currently subscribed to the site, the notification content is transmitted through at least one of a text message transmission and an electronic mail transmission scheme.

In addition, an online site management server for performing an online site operation according to the present invention in order to achieve the above object, the request receiving unit for receiving a request of a predetermined user subscribed to the site; A group generator for generating a group according to the group creation request received by the request receiver; A group which registers at least one of a site member who has joined the site and a non-member who has not joined the site as a member of the created group (hereinafter referred to as a "group member") according to a group member registration request received by the request receiving unit. A member register; A notification target selection unit for selecting at least some of the group members as notification targets for transmission of predetermined notification contents according to the notification contents transmission request received from the request receiving section; A member access determination unit that determines whether there is a group member currently logged in to the site among the notification targets selected by the notification target selection unit; As a result of the determination of the member access determination unit, if there is a logged-in group member, the logged-in group member transmits the notification contents through a communication channel connected by login, and although the subscription is made to the site among the selected notification targets, Group members who are not logged in and non-site members who are not currently subscribed to the site may include a notification unit for transmitting the notification contents through at least one of a text message transmission and an electronic mail transmission scheme.

As described above, according to the present invention, a non-site member can also be joined as a group member to a group of the site, thereby solving the problem of forcing the group members to join the site, and the status of the group members, for example, whether or not to log in. By varying the notification method according to the can increase the efficiency in the cost and speed, and furthermore, site members can easily check the group to which they are registered at the time of member registration or login.

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

An example of an overall communication system including an online site management server 300 according to an embodiment of the present invention is shown in FIG. 1.

As shown in the figure, the entire communication system according to an embodiment of the present invention includes a wired communication terminal 100, an online site management server 300, and a wireless communication terminal 200. In describing the present embodiment, the online site management server 300 functions as a kind of messenger communication management server that enables messenger communication between users as an example.

The wired communication terminal 100 corresponds to a terminal operated by members subscribed to the site to log in, or operated by a non-subscribed member who has not yet joined the site to subscribe to the site.

That is, when the online site management server 300 functions as a predetermined messenger communication management server as described above, a messenger client is installed in the wired communication terminal 100 so that each user subscribed to the site uses a messenger client. Messenger communication can be performed with other users who have subscribed to.

Here, the messenger communication corresponds to a communication performed using, for example, Windows Live Messenger (MSN) or Nate-on Messenger, and since the communication method is only known, a detailed description thereof will be omitted. Any communication that communicates through predetermined data communication corresponds to messenger communication in the present embodiment.

The wireless communication terminal 200 is a terminal configured for site members and non-site members to receive a predetermined message from the online site management server 300. Preferably, the wireless communication terminal 200 is not subscribed to the online site management server 300. Corresponds to a terminal for sending a message to invite members to join the site or a notice in a predetermined group.

Here, the division of the wired communication terminal 100 or the wireless communication terminal 200 is merely divided for convenience of description and the present invention is not limited thereto.

As shown in FIG. 2, the online site management server 300 may include a request receiving unit 310, a notification unit 320, a site member registration unit 330, a group generation unit 340, a group member registration unit 350, and a notification target. The selection unit 360, a member connection determination unit 370, a login processing execution unit 380, and a storage unit 390 are configured to be included.

The storage unit 390 stores a site member database 391, a group information database 392, and a group member database 393, where the site member database 391 includes information about members who have joined the site. The group information database 392 includes information on groups created on the site, and the group member database 393 includes information on members registered in the groups created on the site.

In this case, the creation of a group on the site means that a predetermined group is created at the request of the users in the online site management server 300. For example, the users are newly added to the site for the meeting of people or alumni with the same hobby. Groups can be established.

In the present invention, the group member may be included in the site member but may not be included.

That is, when a group called A is created on a site as shown in FIG. 7, members of the group A may include a1, a2, a3, and a4. Among them, a1 and a2 are members who join the site, but a3 and a4 is a non-site non-site member.

As such groups are created as site sub-organizations (also known as 'subgroups'), the group members who join and register with each group need not necessarily be site members. A more detailed description thereof will be described later.

The request receiving unit 310 performs a function of receiving a request of a predetermined user who wants to join or subscribe to the site as a member, and forms a communication channel with a terminal operated by the user (ie, a wired communication terminal 100). Receive various requests of the user and related information.

That is, the request receiving unit 310 performs a function for receiving various requests and various data related to the request from the terminal operated by the site member from the user. For example, the request receiving unit 310 is a member from the terminal operated by the member. Various requests such as a subscription request, a group creation request, a login request, a predetermined notification content transmission request, and predetermined data or files such as group member information can be received.

When the site member registration unit 330 receives a site subscription request from the request receiving unit 310, the site member registration unit 330 performs a function of newly registering a site member by processing the request. At this time, the site member registration unit 330 registers various kinds of information included in the site subscription request in the site member database 391 of the storage unit 390 to perform a member registration process.

An example of various fields included in site member database 391 is shown in FIG. 8A. Among them, the 'connection status' field is a field for storing information depending on whether the corresponding site member logs in to the site later.

The group generating unit 340 performs a function of creating a group at a site when a request for generating a group is received by the request receiving unit 310.

As described above, a group is created for each site member who joins the site to gather people who have common interests such as reunions, company meetings, social gatherings, and hobbies. The group generator 340 may store information about a group created in the group information database 392 of the storage unit 390 when a group is created. An example of various fields included in the group information database 392 is illustrated in 8b. Has been shown.

According to the group member registration request received by the request receiving unit 310, the group member registration unit 350 converts site members who have joined the site and non-members who have not joined the site as members of a group previously created (hereinafter referred to as "group members"). To register. In this case, the group member registerer 350 may store the group member information in the group member database 393 of the storage unit 390. An example of various fields included in the group member database 393 is illustrated in FIG. 8C.

The notification destination selecting unit 360 performs a function of selecting at least some of the group members as notification destinations for transmitting the predetermined notification contents when the request receiving unit 310 receives the predetermined notification contents transmission request.

That is, the notification target selection unit 360 performs a function of specifying (selecting) at least some of the group members based on a user's request, wherein the selected group member provides predetermined notification contents such as a notice as described below. It is a destination to transfer.

The member access determination unit 370 performs a function of determining whether there is a group member currently logged in to the site among the notification targets selected by the notification target selection unit 360.

For example, the member access determination unit 370 may determine whether a predetermined group member is currently logged in by checking the 'connection status' field of the site member database 391 of the storage unit 390. Here, being logged in includes, for example, logging in via a messenger client.

If there is a logged-in group member among the selected notification targets, the notification unit 320 transmits the notification content to the logged-in group member using a communication channel connected by the login.

For example, the notification unit 320, if the group member corresponding to the selected notification target remains logged in to the site through the messenger client, the messenger client side (that is, the user terminal on which the messenger client is driven). Send the notification. In this case, transmitting the notification contents to the messenger client means transmitting the notification contents through the messenger communication.

In addition, the notification unit 320 is a text message transmission method and electronic message for the group members who have subscribed to the site of the notification target selected by the notification target selection unit 360 but are not currently logged in, and the non-members who do not currently subscribe to the site. The notification content is transmitted through at least one of the mail transmission methods. For example, the notification unit 320 may transmit the notification contents to the wireless communication terminal 200 for non-site members.

That is, as shown in FIG. 8C, the group member information includes a mobile phone number and an e-mail address, and the notification unit 320 checks the group member database 393 of the storage unit 390 to log in among the selected notification targets. Notifications are sent by text message or e-mail to group members who do not, and non-members who are not currently members of the site.

As such, different notification methods are provided depending on whether or not the group members log in to the site, thereby achieving cost reduction and delivering notifications more quickly.

That is, the member who is logged in can be notified of an unnecessary notice through messenger communication, so the cost can be reduced, and a member who does not have a mobile terminal can receive an e-mail. Rather than transmitting through a logged in state, the logged-in communication channel, that is, notifications, etc. can be notified through messenger communication, so that faster notification is possible.

Meanwhile, the notification unit 320 may notify the group member registered by the group member registration unit 350 to one of the mobile communication terminal and the electronic mail by referring to the group member information of each group member. . Of course, the notification unit 320 may notify the logged-in member through messenger communication. Such a notice may be called an invitation and may be configured to register as a normal group member only with the approval of the group member.

To this end, the 'member status' field of FIG. 8C may include information about the current status of each group member, that is, whether it is a non-member or being invited or declined to invite, and other status information of each group member.

Notifying that a member of a site has been registered / registered may be notified at the time of group membership registration as described above, but may be notified when a non-site member registers as a member of the site or when a site member logs in to the site. .

For example, the group member register 350 described above may store at least one of a group member's name, a mobile phone number, an e-mail address, and a social security number as group member information when registering a group member. If the request receiving unit 310 receives a request for membership, the non-site requesting member 310 compares the information of the site nonmember who requested the membership with the group member information stored in the group member database 393 of the storage unit 390. The controller 320 may determine whether there is a group that is previously registered as a group member, and if the corresponding group exists, the notification unit 320 may be notified by using the communication channel requested to join the member. .

In response to this, as the login request by the site member is received by the request receiving unit 310, the log-in processing unit 380 compares the member information of the site member who requested the login with the previously stored group member information to the site member who requested the login. The notification unit 320 determines whether there is a group newly registered as a group member, and if there is a corresponding group, notifies the site member requesting the login using the communication channel requested to log in. To control.

Hereinafter, a control flow of the entire communication system including the online site management server 300 according to an embodiment of the present invention will be described with reference to FIGS. 3A to 6.

First, membership in the site is made as shown in Fig. 3A.

That is, the online site management server 300 that receives a site membership request from a site nonmember who has not yet subscribed to the site (step S1) stores the information input by the site nonmember in the site member database 391 and processes the membership. (Step S2).

Hereinafter, a process of creating a group on the site and registering group members will be described with reference to FIG. 3B.

After the site membership is processed, the online site management server 300 receives the group creation request from the site member (step S11), and stores the group information that the site member inputs and transmits about the group in the group information database 392. (Step S12), a new group is registered.

At this time, the online site management server 300 may notify the member requesting registration of the group to the group registration completion message (step S13).

On the other hand, the site member who created the group can register the information of the people belonging to the created group, that is, the group member information to the online site management server 300. For example, the group member information file including the group member information. It may be transmitted to the online site management server 300. Since a technology related to file transfer or upload on a network is well known, a detailed description thereof will be omitted.

Upon receiving the group member information file (step S14), the online site management server 300 extracts the group member information from the group member information file, and stores and registers the extracted group member information in the group member database 393 ( Step S15).

At this time, the online site management server 300 determines whether the group member registered in the group member database 393 is a member who has already subscribed to the site (step S16).

That is, as described above, the group members may include members who have already subscribed to the site, but may also include non-site members who have not joined the site. It is determined whether the group member is a site member who has already subscribed to the site.

Here, as an example of a method of determining whether a group member is a site member, the online site management server 300 may include a member's name, social security number, and mobile communication stored in the site member database 391 and the group member database 393. At least one of the terminal phone number and the e-mail address may be compared.

As a result of the determination, when the group member is a site member who has previously subscribed to the site, the online site management server 300 includes the group member information by including reference information (for example, a reference number) for referencing the site member database 391. The database 393 performs an update process (step S17).

That is, by referring to the site member database 391 without storing separate group member information in the group member database 393, it is not necessary to manage the information of the corresponding member for each group when the site member is registered in the group. In addition to saving storage space by referring to the site member database 391, if a site member modifies his or her information, updating the site member's information only in the site member database 391 will result in all updated groups. Member database 393 may be reflected.

In the present exemplary embodiment, the online site management server 300 updates the group member information to the site member database 391 after registering the group member information in the group member database 393, but the group member is added to the group member database 393. Of course, it is possible to determine whether the group member is a member of the site in advance before saving the registration.

Hereinafter, a process of controlling the online site management server 300 when a predetermined group member wants to send a predetermined announcement to other group members will be described with reference to FIG. 4.

When the online site management server 300 is requested to transmit a predetermined notification content, for example, a notification from a group member (step S21), the online site management server 300 extracts the notification target group member information based on the information included in the request. (Step S22).

That is, when the notification transmission request includes the IDs of three group members, 'A', 'B', and 'bottle', the online site management server 300 compares the corresponding IDs and displays the information of the three group members. To confirm.

The extracted information may include a mobile phone terminal number or an email address of the group member.

The online site management server 300 determines whether the notification target member is currently logged in (step S23). In this case, whether or not the user is currently logged in may be checked by referring to the 'connection status' field of the site member database 391 of FIG. 8A.

As a result of the determination, if the target group member of the notification group is currently logged in to the site, the online site management server 300 transmits the logged in member to the logged-in communication channel through the logged-in communication channel (for example, the messenger communication when logging in through the messenger client). The notification is notified (step S24).

In addition, the online site management server 300 determines that the group member to be notified is not a site currently logged in to the site or a non-site member who has not yet joined the site. (Step S25). This process is shown schematically in FIG.

As described above, in notifying the notice, by changing the notification method according to whether or not the group member is logged in, it is possible to prevent unnecessary costs and notify the notice more quickly.

Hereinafter, a process of notifying the status of joining a new group when a site member logs in will be described with reference to FIG. 5.

Upon receiving the login request (step S31), the online site management server 300 first determines whether the login requestor is a site member (step S32), and if it is a site member, determines whether a newly registered group exists for the login requestor. (Step S33).

That is, as described above, the group member may be registered and stored by the site member who created the group irrespective of the will of each group member, and in this case, the online site management server 300 may request the site member to log in. It is to determine whether there is a group newly registered as a member of the site member who requested the login.

If it is determined that the newly registered group exists, the online site management server 300 notifies the site member who requested the login that there is a newly registered site group as a group member (step S34) and performs login processing (step S35). . In this case, the notification and the login process may be performed at the same time or may be reversed.

Thereafter, the online site management server 300 asks the site member whether to approve joining the group registered as a group member irrespective of his / her will, and then takes a predetermined action (maintaining group membership or leaving the group). Etc.) may be performed.

This allows the site member to know each group information automatically stored as a group member each time they log in and easily select whether or not to approve it. Accordingly, it is possible to reduce the hassle of site members to visit and request to join a group of sites.

Hereinafter, a process of notifying that a non-site member is already registered in a group when a non-site member joins a site will be described with reference to FIG. 6.

When the online site management server 300 receives a membership request from a non-site member (step S41), it determines whether there is a site group in which the member requester is registered as a group member (step S42).

In this case, whether a member requestor is registered as a group member in a predetermined group is determined by comparing the member information (eg, name, mobile phone number, etc.) input at the time of membership registration with information stored in the group member database 393. can do.

As a result of the determination, if there is a pre-registered site group, the online site management server 300 notifies the requester of membership, indicating that the user is already subscribed to a predetermined group of sites (steps S43 and S44).

Here, the online site management server 300 may process the membership first and then notify that the user is already subscribed to the predetermined group.

Accordingly, site members newly subscribed to the site can easily check the group in which they are registered as group members, thereby increasing user convenience.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
