Description

  The present invention relates to an information communication terminal used for an introduction service or the like.

  There is a service for registering members in a group having a common hobby or purpose through the Internet, or introducing members in a group by searching. The number of users of such services has increased rapidly due to the improvement of the Internet connection environment, especially the spread of mobile communication terminals such as mobile phones, and in recent years crimes by malicious users have become a social problem. While this service allows you to make acquaintances in the virtual world, there are currently some sites where the credibility of registered people is poor and it is difficult to use easily. Therefore, for example, when performing a member search within a group with a specific hobby as a search condition, the search range of members is limited to the acquaintance of the search performer, etc. A safe introduction system has been proposed (for example, see Patent Document 1).

On the other hand, for example, when a member search within a group is performed with a specific hobby as a search condition and information is to be sent to all the relevant persons, a friend created in the information communication terminal owned by the user A search is performed in a list (for example, an e-mail address list), and an e-mail broadcast transmission function is used to send e-mail to all the members in the list.
Japanese Patent Laid-Open No. 2002-169918 (page 4-8, FIG. 1)

  However, in the above-mentioned conventional introduction system, for example, if a malicious user can know a third party's telephone number or e-mail address without any acquaintance and register as if he / she was an acquaintance, There was a problem with the safety of important personal information, such as the possibility that the information of the three parties was unintentionally introduced to another person. In addition, since the reliability of registered persons (for example, whether or not they are really acquainted) is not ensured as described above, the range of introductions and searches is narrowed and effective when trying to improve safety. There was a problem that friend introduction and friend search could not be performed.

  The present invention has been made in view of the above-described conventional circumstances, and an object thereof is to provide an information communication terminal capable of ensuring the reliability of user identification information registered in a list.

  The information communication terminal of the present invention is an information communication terminal that communicates with the other terminal based on the identification information of the user of the other terminal registered in the local terminal side list, and the identification information is Transmitting means for transmitting a registration request for registration to a list to the other terminal, receiving means for receiving a response to the registration request, and registration means for registering the identification information included in the response to the list .

  According to the above configuration, by providing means for registering the identification information included in the response in the list, only reliable identification information that has been approved by the user of the other terminal is registered in the list. The reliability of the user identification information registered in the list can be secured.

  In addition, the information communication terminal of the present invention includes display control means for displaying only publicly available information that identifies the user among the identification information. According to the said structure, since only the information which can be disclosed which identifies a user is displayed among identification information, since information other than the information which can be disclosed can be concealed, the personal information of the registered user can be protected.

  According to the information communication terminal of the present invention, by providing means for registering the identification information included in the response in the self-terminal side list, only reliable identification information that has been approved by the user of the other terminal is included in the list. Since it is registered, the reliability of the user identification information registered in the list can be secured.

  Hereinafter, an introduction system for explaining embodiments of the present invention will be described in detail with reference to the drawings. In the following embodiment, an example of an introduction system using a mobile phone terminal as an information communication terminal will be described.

  FIG. 1 is a diagram showing an internal configuration of an information communication terminal for explaining an embodiment of the present invention, and FIG. 2 shows a system configuration example of an introduction system for explaining the embodiment of the present invention. FIG. The introduction system is composed of a plurality of information communication terminals that can communicate with each other. The information communication terminal mainly includes a control unit 10, a communication unit 20, a personal information registration unit 30, a personal information data area 40, a friend list data area 50, and the like.

  The control unit 10 includes a CPU, a ROM, a RAM (all not shown), and the like, and comprehensively controls the operation of each unit of the information communication terminal. The control unit 10 further includes a friend list registration unit 11, a friend list registration response unit 12, a friend introduction request unit 13, a friend introduction unit 14, a friend introduction response unit 15, an information transmission unit 16, and an information transmission response unit 17. .

  The friend list registration unit 11 has a function of transmitting a registration request for registering identification information to the list to the other terminal, receiving a response to the registration request, and registering the identification information included in the response in the list. Have. The friend list registration means 11 transmits identification information to be described later to the partner information communication terminal, and is transmitted from the partner information communication terminal only when registration of the identification information in the friend list managed by the partner information communication terminal is detected. The registered identification information of the other party is registered in a friend list managed by him / herself. The friend list registration response means 12 responds to a registration request from the partner information communication terminal. The friend list registration response means 12 detects that the other party's identification information has been transmitted from the other party information communication terminal, and only registers his / her identification information in the other party's information communication when registering the identification information in the friend list that he manages. Send to the terminal.

  The friend introduction requesting means 13 requests another friend introduction to the partner information communication terminal registered in its own friend list. The friend introduction requesting means 13 registers the identification information of the introduction target acquired from the information communication terminal of the introduction target in the friend list managed by the friend only when the information communication terminal of the introduction target approves the registration to the friend list, At the same time, it transmits its own identification information to the information communication terminal to be introduced. The friend introduction means 14 can detect a friend introduction request from the partner information communication terminal registered in its friend list and can temporarily communicate with the information communication terminal of the friend introduction request source to the introduction information communication terminal. Is sent to the information communication terminal of the friend introduction request source.

  The friend introduction response means 15 permits introduction to an intermediary terminal that has received an introduction request from a friend introduction request source (introduction request terminal). The friend introduction response means 15 detects the communication information transmitted from the partner information communication terminal registered in the friend list of his / her friend and is temporarily communicable with the information communication terminal of the friend introduction request source, and requests friend introduction Only when the friend registration of the original information communication terminal is accepted, the communication information is acquired, and the identification information of the user is transmitted to the information communication terminal of the friend introduction request source.

  The information transmission means 16 transmits arbitrary information to the partner information communication terminal registered in its friend list. The information transmission response means 17 relays information transmitted from the transmission source terminal, refers to a friend list, identifies a relay destination of received information, and transmits information to the identified relay destination. The information transmission response means 17 receives arbitrary information from the partner information communication terminal registered in its own friend list, compares the received information with personal information described later, and satisfies a predetermined condition (comparison results match). A response to the source terminal is made only when it is determined. Even if the received information matches the personal information, the information communication terminal includes means for restricting a response to the caller terminal when the comparison result is the same by the user's input. , The user can refuse to respond to the originating terminal. Also, the information transmission response means 17 is preset based on the limit information that limits the number of relay stages to transmit the received arbitrary information to another partner information communication terminal registered in its friend list. Repeat as many times as you like.

  The functions of the friend registration list means 11, the friend list registration response means 12, the friend introduction request means 13, the friend introduction means 14, the friend introduction response means 15, the information transmission means 16, and the information transmission response means 17 are controlled. This is realized by the CPU (not shown) of the unit 10 executing a program related to each means. That is, each of the above means is stored in a ROM (not shown) in the control unit 10 in the form of a program.

  The communication means 20 is configured by a communication device for an information communication terminal to communicate with other information communication terminals to perform a call and data transmission / reception. Specifically, the communication means 20 performs wireless communication with a ground base station via a wireless telephone network, and thereafter connects to another information communication terminal via a public telephone network or the Internet network.

  The personal information registration means 30 includes an input unit (not shown) of the information communication terminal, and registers identification information relating to the information communication terminal and identification information relating to the user in a personal information data area 40 described later. Registration is performed according to the input operation of the user of the information communication terminal.

  The personal information data area 40 is a memory area for storing identification information related to the information communication terminal and identification information related to the user. Here, the identification information will be specifically described. The identification information related to the information communication terminal is a telephone number unique to the information communication terminal, an e-mail address, terminal data capable of performing infrared communication or temporary communication, and the identification information related to the user refers to the information communication terminal. The name, age, gender, nickname, and hobby of the user to use. The identification information related to the information communication terminal uniquely corresponds to the identification information related to the user.

  FIG. 3 is a diagram conceptually illustrating a data configuration example of identification information stored in the personal information data area. When transmitting personal information to a partner information communication terminal to be registered as a friend, the friend list registration means 11 selects and transmits only three items: a nickname, a telephone number, and an e-mail address. As shown in the figure, each item is distinguished from disclosure or secrecy. This is because a tag indicating disclosure or concealment is assigned to each data, and this information is retained even when it is registered in a friend list of another information communication terminal. The stored data may be encrypted. Whether or not each item of identification information can be disclosed is set in advance, but for example, whether or not an item with low importance such as gender and age can be disclosed may be arbitrarily set by the user.

  The friend list data area 50 is a memory area for storing identification information acquired from the partner information communication terminal. This memory area is secured in a system area that cannot be accessed by the user of the information communication terminal. When the users of the information communication terminal agree with each other and perform the friend registration operation, the identification information transmitted by the other party is stored in this memory area. FIG. 4 is a diagram conceptually illustrating a data configuration example of identification information stored in the friend list data area. As shown in the figure, the identification information stored in the friend list includes three items: a nickname, a telephone number, and an e-mail address. Even if the friend list is referred to, only items that can be disclosed (for example, nicknames in the example of FIG. 4) are displayed, so that the user cannot grasp and misuse other important personal information. On the other hand, when the user performs an operation such as selecting the displayed nickname when referring to the list, the control unit 10 moves to the information communication terminal corresponding to the nickname based on the identification information stored in a secret manner. Orders the sending of e-mails and e-mails. In other words, important personal information such as phone numbers and e-mail addresses are kept secret, and both parties can make telephone conversations and exchange e-mails based only on nicknames. You can introduce friends and send information. As will be described later, if detailed information about friends (for example, gender, hobbies, etc.) can be stored separately in association with this friend list, the friend list is searched for a specific item, and the friend who matches the condition Can also be extracted.

  Next, the operation of the information communication terminal configured as described above will be described.

  First, a friend registration operation in a case where friend registration is performed between information communication terminals (that is, a user of the information communication terminal A and a user of the information communication terminal B register each other as friends) will be described.

  FIG. 5 is a timing chart showing the flow of the friend registration operation. If the user of the information communication terminal A and the user of the information communication terminal B are acquainted with each other (or are acquaintances with each other), the other party registers with the other party as a “friend” upon consent. To do. First, when the user of the information communication terminal A performs a predetermined operation for registering a friend, the control unit 10a acquires nickname, telephone number, and e-mail address identification information from the personal information data area 40a. Then, the nickname, telephone number, and e-mail address are transmitted to the information communication terminal B via the communication means 20a as identification data for friend registration (step S101).

  The control unit 10b of the information communication terminal B detects the identification information transmitted from the information communication terminal A via the communication unit 20b (step S102), and the user of the information communication terminal B performs the information communication on the received identification information. When an operation of registering in the terminal B, that is, an operation of permitting friend registration is performed, the control unit 10b causes the friend list registration response unit 12b to store the received identification information in the friend list data area 50b. Further, the friend list registration response unit 12b transmits the identification information for friend registration acquired from the personal information data area 40b by the same procedure as described above to the information communication terminal A through the communication unit 20b (step S103).

  The control unit 10a that has received the identification information for friend registration transmitted from the information communication terminal B via the communication means 20a determines that the information communication terminal B has registered the information communication terminal A in the friend list, and the list The registration unit 11a stores the received identification information in the friend list data area 50a (step S104). By the above procedure, friend registration is completed between the information communication terminal A and the information communication terminal B. The friend registration is completed between the information communication terminal A and the information communication terminal C by the same procedure from step S105 to step S108. This creates a friend list as shown in FIG. 4. For example, for a partner who became friends by telephone or e-mail exchange after registering a friend and determined that more detailed personal information may be disclosed. By manually exchanging information on items similar to personal information (see FIG. 3) such as personal information and hobbies, another list including detailed information can be created in association with the friend list.

  FIG. 6 is a diagram illustrating a screen display example of both information communication terminals in each procedure of the friend registration operation. In step S101, the display unit (not shown) of the mobile communication terminal A displays that the other party to register as a friend is the mobile communication terminal B (FIG. 6A). In step S102, identification information is transmitted from the information communication terminal A to the display unit of the information communication terminal B, and it is displayed that the information communication terminal A is waiting for friend registration (FIG. 6 (b)). In step S103, when the user of the information communication terminal B accepts the friend registration on the selection screen (FIG. 6C) displayed on the display unit, the identification information of the information communication terminal A is added to the friend list of the information communication terminal B. The addition is displayed (FIG. 6D). On the other hand, in step S104, the display unit of the information communication terminal A displays that the identification information received from the information communication terminal B has been added to the friend list of the information communication terminal A (FIG. 6 (e)).

  As described above, since both friends cannot be registered without the consent of the other party, high reliability is ensured for the registered friend information. Moreover, since important personal information is not disclosed when the inquiry of friend information is performed, high safety is ensured.

  Next, in response to a request from an information communication terminal that is registering a friend, another information communication terminal that is also registering a friend is introduced (that is, information communication that is a friend of the user of the information communication terminal A) The user of the terminal C is requested to introduce a friend, and after obtaining the consent of the user of the information communication terminal B who is a friend of the user of the information communication terminal A, the information communication terminal B that is the introduction requester The friend introduction operation in the case of transmitting the identification information of C) will be described.

  FIG. 7 is a timing chart showing the flow of the friend introduction operation. Here, an example in which the user of the information communication terminal A tries to introduce the user of the information communication terminal B who is registered as a friend to the user of the information communication terminal C will be described.

  When the user of the information communication terminal C who is registering a friend with the information communication terminal A wants the user of the information communication terminal A to introduce a new friend, the user of the information communication terminal A requests a friend introduction. . First, when the user of the information communication terminal C performs a predetermined operation for requesting friend introduction, the control unit 10c sends a request for friend introduction to the information communication terminal A via the communication means 20 to the friend introduction request means 13c. Transmit (step S201).

  First, the friend introduction request unit 13c acquires identification information of a nickname, a telephone number, and a mail address. Then, “terminal data capable of temporary communication” generated by adding the number of times the data can be used and the conditions for the usable time to the data of the telephone number and the mail address (hereinafter referred to as a temporary terminal ID). Are transmitted as identification data for requesting friend registration via the communication means 20c.

  The identification data for requesting friend registration includes optional identification information such as other identification information (for example, gender and hobbies) stored in the personal information data area 40c, and search conditions for friends to be introduced. Can be sent. Also, if the user of the information communication terminal C does not want to disclose his nickname to the user of the information communication terminal introduced by the information communication terminal A, the “temporary nickname” information (temporary nickname or Corresponding symbols and numbers) may be added as optional information. When using a temporary nickname, the normal nickname is kept secret.

  Upon receiving the friend introduction request from the information communication terminal C (step S202), the control unit 10a of the information communication terminal A causes the friend introduction means 14a to search the friend list 50a (the identification transmitted from the information communication terminal C). When search conditions are added to the information as optional information, only the nickname, telephone number, and e-mail address are stored in the friend list 50. As described above, depending on the list, detailed information such as sex and hobbies is stored. Since there is also friend data stored in association with each other, it is also possible to search using the search condition transmitted from the information communication terminal C as a key). The user selects an appropriate information communication terminal as an introduction destination information communication terminal from among them, and the information communication terminal as the introduction destination may be directly designated manually by the user of the information communication terminal A.

  In the example of FIG. 7, since the information communication terminal B is selected as the introduction destination information communication terminal, the friend introduction means 14a transmits a friend introduction inquiry to the information communication terminal B via the communication means 20a (step S203). . At this time, the friend introduction means 14a transmits the nickname (or temporary nickname) transmitted from the information communication terminal C and the identification information of the temporary terminal ID to the information communication terminal B as they are, and the information communication terminal The information related to the information communication terminal C held by A is not disclosed to the information communication terminal B. That is, the information communication terminal that introduces the friend does not disclose the information of other information communication terminals that the information communication terminal holds.

  The control unit 10b of the information communication terminal B that has received the friend introduction inquiry from the information communication terminal A via the communication means 20b (step S204) waits for a user input indicating whether introduction is possible or not, and the user of the information communication terminal B introduces it. When the acceptance operation is performed, the friend introduction response means 15b is caused to transmit an introduction acceptance response via the communication means 20b (step S205).

  When the user of the information communication terminal B performs an introduction rejection operation, the control unit 10b of the information communication terminal B identifies the nickname (or temporary nickname) of the information communication terminal C and the temporary terminal ID identification information. Do not save. Therefore, the identification information related to the information communication terminal C that is the friend introduction request source is not inadvertently stored in the information communication terminal B, and the safety and reliability of the identification information registered in the friend list is ensured. Can do.

  The control unit 10a of the information communication terminal A that has received the introduction approval response transmitted from the information communication terminal B (step S206) sends an introduction approval response to the friend introduction means 14a via the communication means 20a. (Step S207). Note that since the response is also sent to the information communication terminal C when the response is an introduction refusal, the control unit 10c of the information communication terminal C can receive a response to the friend introduction request via the communication means 20c (step S208). ).

  In step S205, when the friend introduction response means 15b transmits an introduction approval response to the information communication terminal A, the control unit 10b determines that the information communication terminal B registers with the information communication terminal C, and registers the friend list. The means 11b transmits the identification information for friend registration of the information communication terminal B to the information communication terminal C via the communication means 20b (step S209). At this time, communication with the information communication terminal C is enabled because the temporary terminal ID of the identification data for friend registration request transmitted by the information communication terminal C in step S201 is temporarily effective information communication. This is because the mail address of terminal C is included.

  Here, the temporary terminal ID will be described with reference to the example of FIG. The temporary terminal ID generated by the information communication terminal C in step S201 is an ID for allowing other information communication terminals such as the information communication terminal B to temporarily communicate with the information communication terminal C. Generated based on email address. For example, in the case of a mail address, the number of times that the address is used or the usable time is set in the mail address data of the information communication terminal C. For example, when the number of uses is set to once, when an electronic mail is transmitted from the information communication terminal B to the information communication terminal C once, the mail address data is deleted at that time. Therefore, misuse of important personal information of the information communication terminal C can be prevented. Note that users of other information communication terminals such as the information communication terminal B cannot grasp information such as the mail address and the telephone number from the received temporary terminal ID. Since the user of the information communication terminal B uniquely corresponds to the temporary terminal ID with the nickname, only by designating the nickname, the user of the information communication terminal B makes a call or sends an e-mail to the information communication terminal owned by the user of the nickname. Can do.

  The procedure from step S209 to step S212 is the same as the procedure from step S101 to step S104 in the timing chart of FIG. 5 showing the procedure of the friend registration operation described above (that is, the friend list of the information communication terminal B). Since the registration unit 11b and the friend list registration response unit 12c of the information communication terminal C operate to register friends), the description is omitted. With the above procedure, the friend introduction for introducing the information communication terminal B to the information communication terminal C from which the information communication terminal A has requested the friend introduction is completed.

  FIG. 8 is a diagram illustrating a screen display example of each information communication terminal in each procedure of the friend introduction operation. In step S201, the display unit (not shown) of the mobile communication terminal C displays that the other party requesting the friend introduction is the mobile communication terminal A (FIG. 8A). In step S202, the display unit of the information communication terminal A displays that the friend introduction request has been received from the information communication terminal C (FIG. 8B). When a search condition or the like is added as option information from the information communication terminal C and transmitted, the friend introduction means 14a of the information communication terminal A performs a search based on the search condition and extracts an introduction partner (FIG. 8). (C) In step S203, when the user of the information communication terminal A selects the information communication terminal B as an appropriate introduction partner terminal and transmits a friend introduction permission inquiry to the information communication terminal B, the information communication terminal B displays on the display unit. Is displayed that the inquiry has been received (FIG. 8 (d)) At the same time, the display unit of the information communication terminal B displays the nickname (or temporary nickname) of the user of the information communication terminal C that is the introduction request source. ) Is displayed, and when option information is added and transmitted, information on the gender and hobby of the user is also displayed (FIG. 8E).

  The friend introduction permission response (step S205) transmitted from the information communication terminal B is received by the information communication terminal A (step S206) and is transferred as it is to the information communication terminal C as the introduction request source (step S207). At this time, no image is displayed on the display unit of the information communication terminal A (FIG. 8F). On the other hand, when the information communication terminal B responds to the introduction approval, in step S208, a display indicating that the information communication terminal A has succeeded in introducing the friend is displayed on the display unit of the information communication terminal C (FIG. 8). (G) In addition, when the user of the information communication terminal B responds to the introduction approval in response to the display shown in Fig. 8E, communication from the information communication terminal B to the information communication terminal C is started. The communication connection is established based on the temporary terminal ID of the information communication terminal C.

  In the above procedure, the information communication terminal B that has received the inquiry for introducing the friend starts the friend registration procedure before the information communication terminal C of the introduction request source. It is also possible to start the friend registration procedure from the terminal C.

  FIG. 9 is another timing chart showing the flow of the friend introduction operation. Similarly to FIG. 7, this is an example in which the user of the information communication terminal A tries to introduce the user of the information communication terminal B registered as a friend to the user of the information communication terminal C. Compared to FIG. 7, the procedure after step S204 (from step S220 to step S227 in FIG. 9) is different. Since steps S201 to S204 are the same procedure, the description thereof is omitted.

  In step S204, the control unit 10b of the information communication terminal B that has received the friend introduction inquiry adds the temporary terminal ID of the information communication terminal B to the friend introduction response means 15b when the user performs an introduction acceptance operation. Then, a response of acceptance of introduction is transmitted (step S220).

  The control unit 10a of the information communication terminal A that has received the temporary terminal ID of the information communication terminal B and the introduction approval response transmitted from the information communication terminal B (step S221) sends the communication means 20a to the friend introduction means 14a. The temporary communication terminal ID of the information communication terminal B and the introduction approval response are transmitted to the information communication terminal C (step S222). The control unit 10c of the information communication terminal C receives the temporary terminal ID of the information communication terminal B and the introduction approval response via the communication unit 20c (step S223).

  The friend list registering means of the information communication terminal C that has received the response of the introduction acceptance and the temporary terminal ID of the information communication terminal B uses this temporary terminal ID to start a friend registration operation (step S224). . The procedure from step S224 to step S227 is the same as the procedure from step S101 to step S104 in the timing chart of FIG. 5 showing the procedure of the friend registration operation described above (that is, the friend list of the information communication terminal C). Since the registration means 11c and the friend list registration response means 12b of the information communication terminal B operate to register friends), the description is omitted. According to the above procedure, since the information communication terminal C that is the introduction request source starts friend registration, the terminal that requested the introduction does not need to access the request source first. It is also preferable from the viewpoint of not inadvertently transmitting the identification information to the outside.

  The request for friend introduction can be made only to the information communication terminal registered as a friend in the friend list data area 50 of the terminal itself. That is, the friend introduction function can only be used by friends.

  As mentioned above, since the referral to the friend referral requester is not completed without the consent of the referral partner, the new friend introduced is trusted to be a friend introduced by a reliable friend. Sex is secured. Moreover, since important personal information is not disclosed when the inquiry of friend information is performed, high safety is ensured.

  Next, when sending arbitrary information from an information communication terminal to an arbitrary information communication terminal that has registered a friend, the transmitted information is all registered in the friend list of the information communication terminal that is the transmission destination. When transmitted to the information communication terminal (that is, when the user of the information communication terminal A transmits an e-mail to the user of the information communication terminal B who is registered as a friend, the e-mail uses the information communication terminal B as a relay point, The information transmission operation in the case of transmission to the user of the information communication terminal C who is a friend of the user of the information communication terminal B) will be described.

  FIG. 10 is a timing chart showing the flow of information transmission operation. In this example, the user of the information communication terminal A registers only the user of the information communication terminal B as a friend, and the user of the information communication terminal B registers only the user of the information communication terminal C as a friend. explain.

  If the user of the information communication terminal A who has registered friends with the information communication terminal B wants to send information by e-mail to all users registered in his / her friend list and further to the friend, the operation of the information communication terminal A The person sets the number of times that the destination information communication terminal becomes a relay point of the electronic mail (restriction information for limiting the number of relay stages), and then transmits the electronic mail to the user of the information communication terminal B registered as a friend. First, when the user of the information communication terminal A performs a predetermined operation of creating an e-mail and transmitting it to all the information communication terminals registered as friends, the control unit 10a causes the information sending means 16a to send a friend list data area 50. In this case, an e-mail is transmitted to the information communication terminal B via the communication means 20a (step S301). Here, it is assumed that the user of the information communication terminal A presets the number of times the information communication terminal is used as an e-mail relay point as one (relay stage number: 2).

  The control unit 10b that has received the e-mail transmitted from the information communication terminal A via the communication unit 20b causes the information transmission response unit 17b to display the received mail information (step S302). The information communication terminal registered as a friend is extracted from the friend list data area 50b, the relay destination is specified, and an e-mail is transmitted to all the specified information communication terminals. In this case, since the information communication terminal registered as the friend is only the information communication terminal C, the received electronic mail is transmitted to the information communication terminal C (step S303). The control unit 10c that has received the e-mail transmitted from the information communication terminal B via the communication unit 20c displays the received mail information on the display unit (step S304).

  In the above description, the case where the number of times of using the information communication terminal of the e-mail transmission destination as a relay point is set in advance as 1 is described. An e-mail is transmitted to all information communication terminals registered as friends. The identification information stored in the personal information data area 40 can be set as to whether or not to receive an e-mail from a friend, and whether or not an e-mail can be received by the number of times the information communication terminal has been relayed. (For example, an e-mail sent by relaying an information communication terminal twice is sent from a friend of a friend of the mail recipient, and is rejected because it is an e-mail from a distant friend.) Etc.)

  FIG. 11 is a diagram illustrating a screen display example of each information communication terminal in each procedure of the information transmission operation. First, the display unit (not shown) of the mobile communication terminal A displays that the information communication terminal registered as a friend is the mobile communication terminal B (FIG. 11 (a)). (FIG. 11B), an e-mail input screen is displayed (FIG. 11C). When the e-mail created in step S301 is transmitted, in step S302, the information transmission response means 17b of the information communication terminal B notifies the e-mail reception (FIG. 11 (d)) and the contents display (FIG. 11 (e)). )I do. Further, in step S304, the information transmission response means 17c of the information communication terminal C performs notification of reception of electronic mail (FIG. 11 (f)) and content display (FIG. 11 (g)).

  As described above, based on the restriction information specified by the user, information can be sent to the information communication terminal registered as a friend in the friend list of the information communication terminal of the transmission destination. In addition, information can be transmitted to a large number of terminals having a specific relationship such as a friend related to the friend and even a friend related to the friend. On the other hand, since it is possible to refuse the reception of information according to a predetermined condition, it is possible to transmit information that meets the needs of the sender and the receiver.

  Next, another example of the information transmission operation will be described. Here, when searching for a friend using the transmitted information as a search condition (that is, a search for an information communication terminal satisfying a predetermined search condition set by a user of the information communication terminal A is performed first. An information communication terminal that is registered as a friend in the friend list, an information communication terminal that is registered as a friend in the friend list of the information communication terminal registered in the friend list of the information communication terminal A, and the information communication terminal relay the search range. Next, the friend search operation in the case of enlarging the image will be described.

  FIG. 12 is a timing chart showing the flow of the friend search operation. In this example, the user of the information communication terminal A registers only the user of the information communication terminal B as a friend, and the user of the information communication terminal B registers only the user of the information communication terminal C as a friend. explain. The user of the information communication terminal A performs a friend search by setting the hobby information “tennis” from the identification information registered as a friend as a search condition. First, when the user of the information communication terminal A performs a predetermined operation for setting a search condition and a keyword and executing a search, the control unit 10a of the information communication terminal A sends the friend list data area 50a to the information transmission means 16a. The search condition information is transmitted to all the information communication terminals registered as friends (step S401). In this case, the information communication terminal B receives the search condition information via the communication unit 20b (step S402). The information transmission response means 17b of the information communication terminal B searches for the identification information stored in the personal information data area 40b with the search condition information, but the hobby information registered in the personal information data area 40b of the information communication terminal B is “ Because it is “boat”, the target information communication terminal cannot be searched. Here, since whether or not to respond to the transmitted information is set to match the search condition information and the hobby information, the information transmission response means 17b of the information communication terminal B does not respond to the information communication terminal A ( Step S403).

  Next, the control unit 10b of the information communication terminal B causes the information transmission response means 17b to transmit search condition information to all the information communication terminals registered as friends in the friend list data area 50b (step S404). In this case, the information communication terminal C receives the search condition information via the communication unit 20c (step S405). The information transmission response means 17c of the information communication terminal C searches for the identification information stored in the personal information data area 40c with the search condition information. In this case, since the hobby information registered in the personal information data area 40c is “tennis”, the search condition information is matched. The control unit 10c of the information communication terminal C waits for a user input indicating whether or not the response to the friend search is possible. When the user of the information communication terminal C performs an operation of accepting the response to the friend search, the control unit 10c sends a friend to the information transmission response unit 17c. A response to the search is made (step S406). The information communication terminal A (step S407) and the information communication terminal C that have received the response to the friend search can register friends in accordance with the aforementioned friend registration procedure.

  Here, a case has been described in which the user of the information communication terminal A presets the number of times that the information communication terminal is used as a relay point of the search condition information as one time. Search condition information is transmitted to all information communication terminals registered as friends in the friend list of terminal C. Further, the restriction information for restricting the number of relay stages may be arbitrarily set by a user who transmits search condition information. In addition, the identification information stored in the personal information data area 40 may be configured to set whether or not to accept friend search and whether or not to accept friend search based on the number of times the information communication terminal is relayed. (For example, the search condition information transmitted by relaying the information communication terminal twice searches the friend of the friend searcher's friend, so it is a friend search from a distant friend, so the friend search is rejected. Etc.)

  FIG. 13 is a diagram illustrating a screen display example of each information communication terminal in each step of the friend search operation. In step S401, when the user of the mobile communication terminal A inputs a search keyword (FIG. 13A) and starts the search, the search condition information is transmitted to the information communication terminal B in step S402, but the search fails. Therefore, no display is performed on the display unit of the information communication terminal B (FIG. 13B), and no response to the information communication terminal A is performed. Next, when the information communication terminal C receives the search condition information in step S405 and succeeds in the search, a display indicating that a friend has been searched is displayed on the display unit of the information communication terminal C (FIG. 13 (c)). . When the user of the information communication terminal C performs an operation of accepting the response to the friend search (FIG. 13D), a response is transmitted to the information communication terminal A in step S406, and the response is received by the information communication terminal A in step S407. Is displayed (FIG. 13E).

  As described above, since the search condition information can be transmitted to the information communication terminal registered as a friend in the friend list of the information communication terminal of the transmission destination based on the restriction information specified by the user, the friend list managed by the user The search can be performed not only within the terminal but also over a large number of terminals having a specific relationship such as a friend related to the friend and even a friend related to the friend. On the other hand, even an information communication terminal that satisfies the search conditions can reject the response to the caller terminal by the user's selection, so a search that matches the needs of the searcher and search target person is possible. .

  In the above embodiment, the identification information may arbitrarily set other items. In particular, the identification information related to the user may be added with items such as birthplace and current location information of the information communication terminal in addition to the hobby so that the search can be performed using this as a search condition.

  In the above embodiment, the friend list data area is secured in the information communication terminal. However, the friend list may be stored in a database provided on a communication network connected to the information communication terminal. Absent.

  FIG. 14 is a diagram conceptually showing the status of friend registration and friend introduction when a friend list is stored in an external database. By storing the friend list outside the information communication terminal in this way, the information communication terminal does not hold important personal information (confidential information) such as the telephone number or mail address of the other party registered as a friend. An introduction system can be constructed.

  In the above embodiment, a mobile phone terminal has been described as an information communication terminal. However, the present invention is not limited to this, and a communication network such as the Internet such as a PHS phone terminal, a personal computer terminal, or a PDA terminal can be used. It goes without saying that any information communication terminal that can be connected can execute the gist of the present invention.

  The information communication terminal of the present invention includes means for registering the identification information included in the response in the self-terminal-side list, so that only the highly reliable identification information approved by the user of the other terminal is registered in the list. Therefore, it has the effect of ensuring the reliability of the user identification information registered in the list, and is useful for information communication terminals used for introduction services and the like.
