Description

How to set username and system for it {METHOD AND SYSTEM FOR DETERMINING USER NAME}

The present invention relates to a method for setting a user name and a system therefor, and more particularly, to form a human network using friend information registered in a phone book of a mobile communication terminal of users, and to name each of the users included in the formed network. The present invention relates to a method for setting a user name based on an alias registered in a phone book of other users, displaying and using the same for searching, and a system for the same.

Sending a message to another person using an information processing terminal such as a mobile communication terminal or a computer is a common technique. In particular, by using a messenger program, a user can send a message in real time to a user registered in his or her address book, phone book or friend list.

In particular, recently, by using the application of the mobile communication terminal such as Kakao Talk of Kakao Co., Ltd. and My People of Daum Co., Ltd. Services that form a network based on the phone book registered in the network, and make a free message, voice call, video call with various users in the network formed using the wireless Internet is becoming popular. Within such services, users can view information such as personal information registered by other users in their network. However, in the past, only a friend registered in his or her address book or phone book can send a message, so it was difficult to expand the network.

In addition, in the social network service based on the address book or the phone book, it is inconvenient to register a new user's contact in the address book or the phone book before expanding the network. There was a problem that it is difficult to find and find a friend who is not.

In addition, since the human network is partially disconnected by the members who do not subscribe to the social network service, it is difficult to fully reflect the offline real network in the system.

Accordingly, an object of the present invention is to provide a user name setting method and system for allowing a user to expand his / her network by searching for another user and registering as a friend without changing the contents of the phone book of the mobile communication terminal.

Another object of the present invention is to provide a method for setting a user name and a system for automatically setting a user name based on an alias registered by different users for different users.

It is still another object of the present invention to provide a user name setting method and a system therefor which enables a more reliable user search by using a user name automatically set based on aliases of users.

It is still another object of the present invention to provide a user name setting method and a system for allowing a user who does not subscribe to a service to act as a node in a network of other users.

The present invention having such an object is performed by the system in a user name setting system that provides a service using a network between users, and is assigned to the first mobile communication terminal from the first mobile communication terminal of the first user. Receiving the first mobile communication number and the phone book data stored in the first mobile communication terminal; If a user account corresponding to the first mobile communication number is not registered, generating a user account of the first user using the first mobile communication number as an identifier; Updating an alias list of the user account of the third user corresponding to the mobile communication number of the third user included in the phonebook data, based on the received phonebook data; And when a plurality of aliases are registered in the alias list of the updated user account of the third user, selecting one of the plurality of aliases and setting the name as the representative name of the third user.

At this time, if the user account of the third user corresponding to the mobile communication number of the third user included in the phone book data is not registered, creating a user account of the third user corresponding to the mobile communication number of the third user It may further include.

The setting of the representative name may include: setting the registered nickname as the representative name the most times when there is the same nickname registered two or more times among the nicknames registered in the nickname list of the third user; If there is no identical nickname registered two or more times, and there are two or more nicknames in which the character string included in the nickname is common among the different nicknames, setting the common character string registered the most times as the representative name; If there is no identical nickname registered two or more times, and there is no nickname including a common character string, the method may include extracting one nickname according to the registered order or randomly and setting it as the representative name.

In the common string, a string including only a preset common name may be excluded.

The method may further include updating a friend list of the user account of the first user based on the received phonebook data.

In this case, when a search word for friend search is input from the second mobile communication terminal of the second user, the representative name including the search word is searched for from the friend list of other users connected within a certain range in the network, centering on the second user. The method may further include providing user information corresponding to a name to the second mobile communication terminal.

On the other hand, the present invention is a network service server for providing a social network service by using a friend relationship between the user by communicating through a plurality of mobile communication terminals and a wireless network, and a database in which information necessary for providing the social network service is stored And a server, wherein the network service server receives a mobile communication number and a phone book data from an arbitrary mobile communication terminal, and stores a user account corresponding to the mobile communication number of another user included in the received phone book data. A user information manager for updating the alias list based on alias information included in the received phone book; And it may include a name setting unit for setting a representative name of each user by selecting any one of the aliases included in the alias list of each user account.

Here, the name setting unit, if there is the same nickname registered more than two times among the nicknames registered in the nickname list, set the registered nickname as many times as the representative name, if there is no same nickname registered more than two times, If there are two or more aliases in which the string included in the alias is common among other aliases, the common string registered the most times is set as the representative name, and there is no identical alias registered more than once, and the alias including the common string is also included. If not, one alias may be extracted and set as the representative name in the order of registration or at random.

In addition, when the user information manager receives the mobile communication number and the phone book data from any mobile communication terminal, a user account corresponding to the mobile communication number of another user included in the received phone book data is registered in the database server. If not, a new user account corresponding to the mobile communication number of the other user may be created.

The user information management unit may update a friend list of a user account corresponding to the received mobile communication number based on the received phone book data when receiving the mobile communication number and the phone book data from an arbitrary mobile communication terminal. .

The present invention has the following effects.

That is, by allowing a user to search for another user and register as a friend without changing the contents of the phone book of the mobile communication terminal, there is an advantage in that the user's network can be easily expanded.

In addition, according to the present invention, the user name is automatically set based on an alias registered by different users for each user, even if the user does not necessarily set his or her basic name. In addition, the user name of non-members who do not register their own default name is automatically set so that the user name is given to users of all nodes located in the network. There is an advantage that it can.

In addition, the present invention has an advantage that a more reliable user search is possible by automatically setting an alias registered jointly by other users based on the aliases of the users as the user name and using the search.

Furthermore, according to the present invention, the user who does not subscribe to the service also acts as a node in the network of other users, so that the actual network relationship is reflected in the system and the network is disconnected by users who do not subscribe to the service. The advantage is that you can build a larger, more realistic social network.

It is a block diagram.

As illustrated in FIG. 1, the user name setting system 100 according to an embodiment of the present invention communicates data with a plurality of mobile communication terminals 300 through a network 200. Wherein the mobile communication terminal 300 is given a unique mobile communication number, each of the personal support to support the wireless communication system that is given the mobility to communicate with other terminals regardless of place, voice, video, text data, etc. It is a portable terminal.

The user name setting system 100 includes a network service server 110 for providing various services based on a human network between users of the mobile communication terminal 300 according to the user name setting method according to an embodiment of the present invention; It includes a database server 130 for receiving and storing a variety of data necessary to reflect the human network between the user of the mobile communication terminal 300 in the service.

The mobile communication terminal 300 downloads a network service program that operates in conjunction with the network service server 110 in an application store where various application programs executable in the mobile communication terminals are traded, or directly the network. By accessing the service server 110, a service is provided while exchanging data with the network service server 110.

In this case, the service provided by the network service server 110 forms a connection relationship between the users of the mobile communication terminal 300 based on the phone books stored in the respective mobile communication terminals 300, thereby allowing each mobile communication. The user of the terminal 300 exchanges messages with other users who are connected to each other, or views or shares each user's contents (text, image, video, and audio) with each other, and further, has no direct connection. It means a social network service that enables a network of contacts.

The network service server 110 reads the phone book from the mobile communication terminal 300 and transmits the phone book data to the network service server 110 as shown in FIG. 2, and uses the transferred phone book data. The user information management unit 111 creates a friend list of the user by using the mobile communication number registered in the user's phone book and updates the alias list of the mobile communication number users registered in the user's phone book. In addition, the network service server 110 includes a name setting unit 113 that selects one alias from the alias list managed by the user information management unit 111 and sets it as a default name of the user. A service provider that manages a network between users by identifying a connection relationship of each user using a friend list of and provides a social network service such as message exchange, social networking, and friend search between users based on the network ( 115). In this case, the user information manager 111 may extract only some information including a mobile communication number and nickname information from contact information of each friend included in the phone book.

Defines a term used to describe a friend search method using the user name setting system 100 according to an embodiment of the present invention having the above configuration.

First, 'user' refers to a subject of use of the mobile communication terminal 300, and indicates each subject used by the mobile communication number of the mobile communication terminal 300. 'User' is a person who can enjoy the service provided by the user name setting system 100 using the mobile communication terminal 300, and only a service subscriber (member) provided by the user name setting system 100. It is also used as a comprehensive concept that includes nonmembers.

In addition, the 'mobile communication number' means a unique number assigned to each of the mobile communication terminals 300, and is a total of 10 digits or 11 starting with 010, 011, 016, 017, 018, 019, etc. based on the present Korea. It becomes a string of digits. However, this is not necessarily the case. Any identification string used with a specific rule as a unique identifier of the mobile communication terminal 300 and a unique identifier for distinguishing each user may be the mobile communication number.

The phone book is a data set of contact information of one or more users stored in the mobile communication terminal 300 and managed as a list. The contact information of each user included in the phone book identifies a plurality of friends. In order to include a friend's nickname information, a mobile communication number, an address, an e-mail address, a home phone number, etc. input by the user of the mobile communication terminal.

In addition, the user 'friend' is another user including contact information in the phone book registered in the user's mobile terminal 300, the data of the phone book registered in the user's mobile terminal 300 is the user By registering in the name setting system 100 means the other user registered in the friend list of the user account managed for each user in the user name setting system 100, the friend also the mobile terminal 300 Because it is a user of, it is identified by a mobile communication number.

And the 'member' is a user of the mobile communication terminal 300, has a user account in the user name setting system 100, the user account is a friend list based on the phone book stored in the mobile communication terminal 300 Refers to a registered user. On the other hand, 'non-member' is a user of the mobile communication terminal 300, the non-member account identified using the mobile communication number of the mobile communication terminal 300 is generated in the user name setting system 100, but generated An account refers to a user having an account not only registered with a friend list but also no information actively input by the user. That is, the non-member means a user who functions as one node in a network between users formed in the user name setting system 100 to serve as a stepping bridge between other members.

A friend list is a user list registered to each member account in the database server 130. The friend list is an identifier of a friend of each member, and a member's mobile communication number and a member for each friend. Alias information registered in the mobile communication terminal 300 is included.

In addition, "nickname" is a character string set by the user in correspondence with each of the mobile communication numbers registered in the phone book of the mobile communication terminal 300, and moves to identify the users corresponding to the respective mobile communication numbers. It may be a name, nickname, abbreviation, etc. of another user arbitrarily determined by the user of the communication terminal 300.

In addition, the 'alias list' is a list of user's nicknames registered in each user account (including both member accounts and non-member accounts), and includes nicknames given to each user by other users who are friends. Furthermore, the alias list may be included in association with each alias and the mobile communication number of another user assigned the alias.

In addition, the 'representative name' refers to a basic name of a user registered in each user's account. If the user is a member, the name may be selectively set directly or automatically set by the name setting unit 112. The representative name is a name provided by default when the user is displayed to other users, and used as data to be compared with a search word when searching for a user.

Furthermore, in the following description, the term 'third user account' is used to describe a user account of another mobile communication terminal user based on a specific user.

Hereinafter, a user name setting method using the user name setting system 100 having the above configuration will be described in detail. 3 is a flowchart illustrating a network formation step by step in the user name setting method according to an embodiment of the present invention, Figure 4 is a step by step user search process using a network in the user name setting method according to an embodiment of the present invention It is a flowchart shown. 5 is an exemplary diagram of a human network for explaining a user name setting method according to an embodiment of the present invention, Figure 6 is an exemplary diagram showing each user information management state in the human network shown in FIG.

First, in the user name setting method according to an embodiment of the present invention, the process of forming a network between the users of each mobile communication terminal 300 is performed by any user ('first user') as shown in FIG. 3. By using the mobile communication terminal 300 of the first user's mobile communication terminal 300, the user name setting system 100 of the first user's mobile communication terminal 300 (hereinafter, Receiving the mobile communication number of the first mobile communication terminal 300 (hereinafter referred to as 'first mobile communication number') and the phone book data stored in the first mobile communication terminal 300 It is performed (S100). Here, the phone book data received by the user name setting system 100 may include all data included in the phone book, but some of them, particularly the mobile communication numbers of the friends of the first user included in the phone book. It may also include only nickname information assigned to each friend by the first user.

The user information management unit 111 determines whether a first member account corresponding to the received first mobile communication number is registered in the database server 130 (S110). If there is no first member account corresponding to the first mobile communication number, a first member account having the first mobile communication number as an identifier is registered (S120).

In addition, when a first member account corresponding to the first mobile communication number is already registered in the database server 130, the user information management unit 111 receives a phone book received from the first mobile communication terminal 300. Based on the data, the friend list of the first member account is updated (S130). As described above, the friend list may store mobile communication numbers of users included in the phone book data and nickname information registered by the first user in the phone book corresponding to each other.

In addition, the user information management unit 111 has a third user account corresponding to each of the mobile communication numbers included in the phone book data received from the mobile communication terminal of the first user in step 100 (S100). It is checked whether or not it is registered in advance (130) (S140). In this case, the phone book data includes mobile communication numbers of at least one other person registered by the first user in his / her phone book and alias information corresponding thereto, and a third user account corresponding to each of the mobile communication numbers of the other users is included. It may be checked whether or not it is registered in the database server 130. Here, only when the third user account is registered in the database server 130, the user information manager 111 displays the alias information included in the phonebook data by the third mobile communication number corresponding thereto. It is registered in the alias list of the user account (S160).

In addition, when the check result in step 140 (S140), there is no third user account registered in advance for a specific mobile communication number of the mobile communication numbers included in the phone book data received from the mobile communication terminal of the first user After registering a new third user account in the database server 130 for the mobile communication number that does not have a corresponding third user account (S150), an alias list is created in the newly registered third user account to generate the first user. It is also possible to register the alias information extracted from the telephone directory data of.

That is, the user information management unit 111 may create a member account of the user when the user directly accesses the network service server 110, and has never accessed the network service server 110. It is also possible to create a non-member account corresponding to the mobile communication number of the terminal. In this case, only non-member mobile communication numbers and aliases assigned by other users who registered the non-member mobile communication numbers in the phone book are registered in the non-member account.

Before explaining the steps described above with reference to FIGS. 5 and 6 in detail, the human network shown in FIG. 5 will be described briefly. A user shown in solid line is connected to the user name setting system 100. Users who have provided their phonebook data, i.e. members, and users indicated by dotted lines have never connected to the username setting system 100, and their friend list is registered in the username setting system 100. Users are not, that is, nonmembers.

The arrows indicated by solid and dashed lines respectively indicate that the user who sent the arrow registered the user who received the arrow as a friend. In other words, the user of the point where the arrow ends in the phone book of the user's mobile terminal at the point where the arrow starts Indicates that the mobile communication number of is registered.

In addition, the string in the box on the arrow indicates the nickname assigned by the user who sent the arrow to the user who received the arrow. Indicates information stored under an alias corresponding to the number. For example, in the phone book of Lee Hyo-jun's mobile communication terminal, Noh Hyo-min's mobile communication number "010-2222-2222" and the corresponding nickname "cute little brother" and Choi Yun-jeong's mobile communication number "010-5555-5555" And the corresponding nickname "My friend" are registered. On the other hand, Song Ji-young, Noh Hyo-min and Choi Yun-jeong register Lee Hyo-jun's mobile communication number "010-1004-1004" in the phonebook of his mobile communication terminal, and renamed Hyo-jun's nicknames "Hyo-joon", "Hyo-jun brother", It was registered as "Hyojun Lee".

If such a human network is reflected in the system, it is as shown in FIG. In the member account of Lee Hyo-jun in the database server 130, the mobile communication numbers of Noh Hyo-min and Choi Yun-jung, which Lee Hyo-jun has registered as friends, and nickname information corresponding thereto are registered as friend lists. In addition, Lee Hyo-jun's member account stores a list of nicknames registered with other users (Song Ji-young, Roh Hyo-min and Choi Yun-jung) who registered Lee Hyo-joon to Lee Hyo-joon. As shown in FIG. 6, the alias list and the mobile communication number of the user who assigned the alias may be registered together.

On the other hand, a non-member account of Kim Ji-eun, a non-member, can also be created in the user name setting system 100. The user information received from the mobile phone terminal of Noh Hyo-min, Song Ji-young, and Choi Yun-jeong, who registered Kim Ji-eun as a friend. After the management unit 111 creates a non-member account using the mobile communication number "010-3333-3333" of Kim Ji-eun included in the phonebook data of Noh Hyo-min, Song Ji-young, and Choi Yun-jeong, the nicknames registered by Noh Hyo-min, Song Ji-young, and Choi Yun-jeong respectively. It is made by registering "Kim Ji-eun", "Ji-eun" and "Kim Ji-eun" in the alias list of the non-member account corresponding to the mobile communication number "010-3333-3333".

Here, the database server 130 may include a member database 130a and a non-member database 130b, respectively, as shown in FIG.

When the alias list of each user is generated in the user name setting system 100 as described above, the representative name of each user can be set using the alias information registered in the alias list.

That is, when a new alias is registered in an alias list of an account of an arbitrary user (S200), and if a plurality of aliases are registered in an alias list of the corresponding user account, the name setting unit 112 is mutually registered among the aliases registered in the alias list. It is determined whether there is a matching alias (S210).

If some of the nicknames registered in the nickname list of any user's account match each other, the nickname with the largest number of nicknames matching each other is registered as the representative name (S220). For example, if two aliases 1 and three aliases 2 are registered in the alias list of user A, alias 2 is registered as the representative name. In FIG. 6, in the case of non-member Kim Ji-eun, "Kim Ji-eun" registered twice among three registered nicknames is registered as the representative name.

However, if there is no alias matching each other, it is determined whether there is an alias including a string matching each other in the plurality of aliases (S230).

Accordingly, the name setting unit 112 selects and registers the string registered most often in the alias list among the strings matching each other as the user's name (S240). In FIG. 6, in the case of the user Lee Hyo-jun, there are no aliases that match each other in the alias list, but all three aliases include the string "Hyo-jun", and "Hyo-jun" is selected and registered as the representative name.

However, if it is determined that the registered nicknames are different from each other and there is no common string, one of the registered nicknames may be selected at random or in order to be registered as the representative name.

 In this case, in steps 220 and 240, common nouns or exaggerations representing relationships between people, such as "mother", "mother", "dad", in extracting aliases or strings matching each other, Aliases or strings containing only common nouns representing only a person's position, such as "manager" and "representative," may be preset to be excluded from the extraction target. However, when such a common noun is combined with another string before it, when the combined other string and common noun are included in a plurality of registered aliases as a whole, they may be set as the representative name in the combined form.

Registering the most frequently repeated character string as the user's name means that the repeatedly registered string among the aliases registered by the user's friends on his mobile terminal is likely to be the actual name of the user. Since it is high, the representative name is extracted based on the alias list and registered as the name to be displayed by default.

As such, when the name of each user is set, various other social network services are provided based on the name of each user. The service providing unit 113 is based on the representative name of each user account managed by the user information management unit 111 and the name setting unit 112, other friend list, etc. Providing lists allows users to exchange messages or share content, form friendships, or search for other users who want to make friends. When a specific user is displayed in another user's friend list or when the user browses his friend's friend list, the representative name automatically set by the name setting unit 112 is displayed for each user included in the friend list. Can be displayed. Furthermore, even when users search for other users, each user may be searched based on the representative name set as described above. For example, if any user searches for a user using "Ji" as a search word in FIG. 6, Kim Ji-eun registered with the representative name "Kim Ji-eun" may be searched. Non-members are therefore searchable. Particularly, if members have their own representative name, they can register the name they want as the representative name, but for non-members, each member name is set in this way.

In the case of friend search, all users having the same or similar representative name as the search word may be searched. However, the service provider 113 inputs the search word in the network formed through the friend list of each user. You can limit the range around the user so that only users within the limited range are searched. For example, as shown in FIG. 5, when each user is a node and the friend relationship is indicated by an arrow, the distance is not more than two arrows, not more than three distance ranges, etc. around the first user. May be limited. When the non-member account is also managed in the database server 130, each user including the non-member as a node, it is possible to determine the scope of the search. For example, when A is a friend of B, B is a friend of C and D, and C is a friend of D, the relationship between A and D may be expressed as a relationship in which ABDs are sequentially connected. ABCD may be expressed as a sequential connection, where the number of each connection relationship between A and D (the number of arrows in FIG. 5) is the distance between the two, and A and D are 2 or 3, respectively. Have distance. Therefore, in the present invention, the distance between users means the shortest distance between two users.

In particular, when expressing such a connection relationship, each user exists as a node between the connection relationships, and even if any one of them is a non-member, the shortest distance can be found by being recognized as a node between each connection relationship. . For example, A, B, C, and D are all members, and ABCD is connected in sequence, while A is a nonmember (E) as a friend, and D is also a nonmember (E). In the case of a friend, a connection relationship is formed between A- (E) -D so that the distance between A and D can be expressed as distance 2 instead of distance 3. For example, if the friend search range is limited to distance 2, D may be excluded from the search result if A does not recognize (E) as a node even though A searches for friend by inputting the name or nickname of D as a search word. . However, by recognizing (E) as a node, the result of searching for D can be obtained. As a result, A and D who know E together offline can be friends with each other online.

When the searched user is displayed, the representative name set by the name setting unit 112 may be displayed together, and the network between the user and me may be displayed using the representative names of other users connected between the user and me. have. For example, if A searches for D, and the shortest distance network is ABCD, this connection relationship is displayed as the terminal of A, but the user name of B and C is displayed together, so that A connects to D through some path. It can be displayed.

In this case, for example, if the other user searched by the first user is not a friend registered in the first user's phone book, the search result may not expose the mobile communication number of the searched other user, and the searched other user may be a non-member. In this case, the social network service may send an invitation message inviting a non-member to a network service provided by the network service server 110 in a short message (SMS) format. In this case, the invitation message may be provided with URL information for accessing the user name setting system 110 or an address for downloading an application operated by the network service server 110.

In addition, each user can register their own personal information, photos, and other data according to the service provided by the service provider 113 in their account to enable others to view or share them with others. .

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
