  In addition, the communication terminal can request participation from other members (users) after acquiring the second information. Moreover, when selecting the member, the person who can come to the meeting point within a predetermined time is searched based on the position information of the person registered in the address book stored in advance in the communication terminal. Is displayed on the display. When any of the seasonal information displayed on the display unit is selected, the communication terminal transmits information requesting the start of group communication to the personal communication terminal via the management device. When a positive response is transmitted from the personal communication device to the management device, the personal communication terminal is newly enabled for group communication.

  According to the present invention, it is possible to reduce the load on the communication terminal during group communication by a technique called PTT or PoC, and when the meeting place is not specified between users, the optimum candidate place considering the position of each user. Can be presented and convenience can be improved. That is, it is possible to set a meeting place (waiting) with a higher degree of freedom and convenience. By providing meeting place candidates, it is possible to differentiate from communications by e-mail, etc., and when providing meeting place candidates, increase the added value of group communication services, such as displaying advertisements that are difficult for users to smoke Is possible.

  Before describing the principle of the present invention in detail, a group communication technique will be described using a mobile communication system as an example. A communication service has been realized that allows multiple communication terminals (members) connected to enable half-duplex communication through a server to exchange text, voice, images, etc. (PTM <Push To Multimedia>: Hello) Messenger service (KDDI au). Taking the Hello Messenger service as an example, the organizer (mobile body calling for a pseudo-meeting) can call other communication terminals to join the meeting, and the participating members can send and receive text, audio, images, etc. This is a group communication service.

  Specifically, one communication terminal that is permitted to transmit by the group communication management device among a plurality of communication terminals can transmit data (text, voice, image, etc.) to other communication terminals. The communication terminal desiring data transmission transmits a communication permission request to the group communication management apparatus. Each communication terminal has a display unit capable of displaying various information provided from the group communication management device. When the communication terminal requests the above-described communication permission from the group communication management apparatus, information regarding the communication terminal currently waiting for communication permission in the communication system is transmitted from the group communication management apparatus to the communication terminal. The communication terminal receives information from the group communication management device and displays it on the display unit.

  Here, the group communication management device is a device that manages group communication by a plurality of communication terminals. Upon receiving a group communication start notification from one communication terminal, the group communication management device calls the counterpart communication terminal in response to the request and establishes a communication session. After establishing the communication session, the group communication management device relays data transmitted from one communication terminal to a plurality of communication terminals. In other words, data transmitted from the transmitting communication terminal to the receiving communication terminal is temporarily received and transferred to the receiving communication terminal. Also, the group communication management device receives the transmission permission request of each communication terminal, lists the transmission request of each terminal in the order received, and the next terminal on the list every time transmission of the currently transmitting terminal ends Are allowed sequentially.

  In addition, navigation devices that search for and display routes for mobiles to reach their destinations using location information detection and map information using GPS satellites, mobile phone base stations, etc. are also used for car navigation, mobile phones, etc. Widely used. An application form of such a navigation function, in particular, a service in which users of a plurality of communication terminals meet (meeting) is considered to be meaningful in improving user convenience in the future.

  Then, according to the present invention, it is possible to provide a mobile communication terminal and a communication system that allow an optimum meeting place to be set in a mobile communication terminal and further invite members by the meeting place. It becomes. In order to help understanding of the present invention, the most basic configuration of the present invention is shown below.

  In a mobile communication terminal having a pseudo meeting function, the server collects position information of each member participating in the pseudo meeting being connected. The server has a function of searching for a meeting place candidate in accordance with the meeting purpose derived from the collected location information of each member and the communication content (text / voice) in the pseudo-meeting and the mood of the user layer user. The mobile communication terminal receives and displays the meeting place family assistant from the server for the pseudo-meeting (assuming that this display is accompanied by an advertisement and enables each member to perform a unique display). In addition, the mobile communication terminal has a new location information that has been recorded in each member's phone book or server from the candidate location (or the determined location) that meets conditions such as proximity or traffic convenience. Has the ability to search for members. The mobile communication terminal displays the searched member (preferably only displayed on the terminal when searching from the terminal phonebook), invites this member to pseudo-mating (requests participation), and It has an additional function of adding meeting place information to this new member participation request message (email etc.).

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a configuration diagram showing a configuration of a group communication system according to the present invention. The mobile phone 10 which is a component of the group communication system includes a main control unit 11 composed of arithmetic means such as a CPU, a storage unit 12 such as a memory, a presentation unit such as an LCD (display means) and a speaker (voice output means). 13. Buttons, microphones, input unit 14 such as touch panel provided on LCD, wireless unit 15 connected to network such as public network via antenna ANT1, GPS unit communicating with GPS satellite via antenna ANT2 It consists of 16 mags. The mobile phone 10 is connected to a network 20 such as a public network via an antenna ANT1, and can make a call and transmit / receive data. In addition, it is possible to communicate (pseudo-meeting) with one or more other mobile phones using text, voice, photo data, etc. by connecting to the pseudo-meeting server 21 that functions as a group communication management device via the network 20 or the like. It is. Further, the mobile phone 10 can acquire the position information of the own terminal based on a GPS signal from a GPS satellite or a signal (cell information) from a mobile phone base station or the like. The mobile phone 10 can also be connected to a navigation server 22 that provides navigation information to a destination by map information, route setting, etc. via the network 20 or the like, and can appropriately obtain navigation information. In the following, an LCD is taken as an example of the presentation unit 13 of the mobile phone 10. In accordance with the screen transition, a meeting place between members is determined during the pseudo meeting, and additional members are invited to the pseudo meeting based on the meeting place. A series of flow will be described.

  4 and 5 are screen transition diagrams of the mobile phone according to the present invention. As shown in FIG. 4, the screen D1 includes areas such as a member list ML, a message column C1, and an advertisement column AD1 in the pseudo meeting. In the message column C1, posted text (chat) of each member and information from the pseudo meeting server are displayed in a timely manner. In addition, a member list ML being displayed is displayed as a member list ML, an advertisement column AD1 is displayed as a banner advertisement, and touch panel soft keys SK1, SK2, SK3, and the like which are operation guide displays for assisting a user operation. In this example, three members are participating in a simulated meeting. When the user presses the [Navi] soft key SK1, the screen changes to a screen D2. In the screen D1, the user (user of the mobile phone 10) is “tallow” on the screen.

  Screen D2 is a diagram in which “waiting search” is selected from the menu presented in menu display MN1. When “Waiting search” is selected, the screen changes to screen D3. The screen D3 is a screen for selecting a member to wait for in order to determine a meeting place. On screen D3, all three users are selected in member selection field MS. When a member is determined, the screen changes to screen D4. On the screen D4, a genre selection field JS for selecting a genre of the meeting place is popped up in the center of the screen for determining the meeting place. “Shopping” is selected from among the genre options presented in the genre selection field JS of the screen D4. At this time, it is desirable to determine and configure the genre from the posted contents of past members by morphological analysis in “analysis from chat”. When the genre is determined, the screen transitions to screen D5.

  From speech information other than text, a speech composed of a plurality of parts of speech / words is first generated by a speech recognition unit (not shown). Morphological analysis is performed on the generated text or chat text information, and a word (part of speech) is extracted. As morphological analysis software (system), for example, there is a teacup etc. After such software is installed in a mobile phone, or a sentence file is sent to an external server etc. and words are cut out by the morphological analysis system The number of occurrences (frequency) is counted for each word, and the following table is created.

  Such a table may be created from information (characters, voice, etc.) exchanged in a group call of the group communication session, but each user who participated in the pseudo meeting (session) has communicated in the past. Past information (email, chat, voice call, etc.) may be added. When past information is added, it is possible to provide a gathering place candidate that takes into account not only the atmosphere of the group call session and the development of the talk but also the hobby, taste, personality, etc. of the participant. In the example of this table, a genre selection dictionary or the like is referred to, and words are searched in order from the word having the highest appearance frequency except for the names of participants. In this case, the genre “meal” corresponding to the word “Japanese food” having the highest frequency is automatically selected. The corresponding genre may be a large classification such as “meal” or a small classification such as more detailed “Japanese cuisine”. For example, the following genre selection dictionary is prepared.

  Returning to the explanation of FIG. 4, the screen D5 is a screen that displays a result of searching for an optimum meeting place for the participating user from the input content. The user can transmit (post) the search result to the pseudo meeting or redo the search. When the search result is selected and the [Send] soft key SK2 is selected, the screen changes to a screen D6 (FIG. 5).

  As shown in FIG. 5, the screen D6 is a diagram in which the search result is posted and displayed on the pseudo meeting screen. The search result is displayed as hyperlink text, and when the search result is selected (the screen with the cursor placed on the search result is not shown), a map display or a new member search function from a menu can be executed. When the map display is selected, the screen transitions to the screen D7 displaying the map MP, and when the menu key is pressed, the screen transitions to the screen D8. In addition, after receiving the search result, it is desirable to configure the banner advertisement so that information at a position close to the search result is received from the pseudo meeting server and displayed. On the screen D6, an advertisement of “Karaoke ABC” located in “xx station square” is displayed in the advertisement column AD2 corresponding to “xx station square” displayed in the message column C6 as a selection result.

  The flow from the input of search conditions (members and genres) to the search result display / pseudo meeting display will be described with reference to the flowchart of FIG. As shown in FIG. 2, when the pseudo-meeting server receives a waiting search instruction, the pseudo-meeting server searches the pseudo-meeting for user location information that has already been registered (step P1). Is acquired (step P2). If it is determined in step P1 that the data is not in the server, the user 1 is requested to transmit the position information to the pseudo meeting server (step P3), and if the position information request is permitted, the position information is transmitted to the user 1 (Step P2).

  A series of processes (steps P5 to P8) are performed for the number of selected users n. When these processes are completed, it is determined whether or not position information has been acquired even for one user (step P9). If it is determined that the position information has not been acquired, text such as “cannot be searched” is transmitted to the user for display, and the process ends (step P10). If it is determined that the information has been acquired, the positional information is transmitted to the navigation server to search for an intermediate point (more precisely, a point where each user can access at as even time as possible) (step P11). After the search in step P11, when the intermediate position search result (or search end signal) is received from the navigation server, the pseudo meeting server further transmits the genre information transmitted from the user to the navigation server, and changes the genre near the intermediate position. Search for information on suitable facilities and places (step P12). When the search result is received from the navigation server, the pseudo meeting server transmits the search result to the mobile phone that transmitted the search instruction, and the mobile phone displays the search result on the display (step P14, screen D5). Furthermore, when the user performs a search result transmission operation from the mobile phone, the pseudo meeting server posts the search result (URL) to the pseudo meeting (step P15, screen D6).

  Returning to the explanation of FIG. 5, the screen D7 is a map display screen that is displayed by selecting a search result (hyperlink text) and connected to the navigation server. From this screen, navigation (direction guidance) is started. Is possible. The screen D8 is a selection screen for selecting how to use the search result. In addition to soliciting additional members, it is desirable to be able to save search results in the address book, send e-mails, etc. When “Additional member search” (solicitation of additional members) is selected, the screen changes to screen D9. Screen D9 is a selection screen for searching for additional members to invite. Select "From Address Book" to search for registered data close to the search result from the location information in the address book information recorded on the mobile phone, and select "From Server" to share address book information on the pseudo meeting server. Search the registered data close to the search result from the location information in the list, and select “From connected” to search the registered data close to the search result from the user who is currently connected to the virtual meeting server or other virtual community. It is possible to find additional members. In addition, it is desirable to divide the information so that information close to the search result can be specified by time or the like (within 30 minutes in the screen example).

  When “From Address Book” is selected, the screen changes to screen D10. The address book is illustrated below. As shown in the table, a registered name (user name, nickname, etc.), some communication identifier (mobile phone number in this example) associated therewith, and location information of this user are associated with the address book.

  FIG. 6 is a diagram showing map information that conveys a range that can arrive at A station within 30 minutes when the meeting place candidate is A station. This map information is obtained by requesting the navigation server from the communication terminal. As shown in the figure, reach station A (exemplified by train, but may be a bus or other transportation) within 30 minutes on foot RA, walk to station B, then use train from station B A range RB that is a peripheral region of B station that can be reached in 30 minutes on foot / train in total, and a range RC that is a peripheral region of C station are displayed. As shown in the figure, since the time required for the train is long at a station (referred to as a relay station) that is far from the meeting place candidate, it is necessary to set a short walk time to the relay station. That is, as the relay station moves away from the meeting place candidate station, the range centered on the relay station must be set smaller. In this figure, the relationship of radius r1> radius r2> radius r3 is established. The navigation server may provide such map information, or geographical information such as latitude, longitude, geographical information such as a radius of Km from the point, or an address display such as A town 1-chome to 5-chome. Information may be provided. The navigation server usually has detailed route information and a function for calculating the required time between multiple points. By using these functions, instead of a simple circular area, the required time to the station is specified. It is also possible to set the range as a range. A mobile terminal (or a navigation server or a pseudo meeting server) can easily and automatically search and extract users to be invited by matching such geographical information with the address book. In this example, the user “Ken” having the location K1 (A town 5 chome) within the range RA as location information is extracted.

  Returning to the description of FIG. 5 again, the screen D10 displays a search result screen for additional members. It is possible to select desired data from the retrieved data and send an invitation message to the pseudo meeting. The user who has received the message can participate in this pseudo meeting.

  FIG. 3 is a flowchart showing the flow of searching for additional members. As shown in the figure, the cursor is placed on the position information URL (search result hyperlink text on the screen D6) (step P20), the position of the cursor is read, and if the operation is a map display operation, the process proceeds to step P22 ( To screen D7). If the operation is a menu, a menu display operation is performed, and the search condition (position information) is acquired from the position information of the destination and the search range that defines the required time from the destination (step P23). When an additional invitation is selected from the menu, “from address book”, “from server”, and “from connected” are presented as search method choices, and one of these can be selected ( Step P24).

  When “From Address Book” is selected, the search condition (search result position information and search range) is transmitted to the mobile phone (P25), and data matching the search condition is searched from the local address book in the mobile phone ( P26). When “From Server” is selected, the pseudo meeting server searches the shared address book on the server for data that matches the search condition (P27). When “From connected” is selected, data matching the search condition is searched from the connected user data in the pseudo meeting server (P29). In this case, as a search condition, it is preferable to search only user data with a status that the corresponding position may be notified in step P28 before step P29. If there is no relevant data from the search (P30), a message such as “no relevant data” is sent to the mobile phone (P31). If the corresponding data exists, the corresponding data is transmitted to the mobile phone and displayed on the mobile phone display (P32, screen D10).

 When it is selected that the invitation mail transmission operation is performed on the mobile phone with respect to the search result (P33), an invitation message to the pseudo meeting is transmitted with the search result as a destination (P34). The invitation message is added with the content selected as the meeting place (position information selected in P20), and the destination user is notified that the invitation to the pseudo-meeting is related to the meeting. When an operation for posting the search result to the pseudo meeting (chat) is selected for the search result, the search result is posted on the pseudo meeting and displayed on the display of the mobile phone (P35).

  FIG. 7 is a conceptual diagram illustrating candidate point calculation and meeting place candidate generation according to the present invention. As shown in the figure, let us consider generation of a candidate for a meeting place when group communication is performed by three communication terminals (users) T1 to T3. For convenience of explanation, it is assumed that the communication terminals T1 to T3 are located on the circumference of a concentric circle centered on the center point CTR. That is, if the radius r from each terminal to the center point is a road, the communication terminals T1-T3 can arrive at the center point CTR through the road in the same required time. Accordingly, if the state of the route from each user (in this case, the road) can be ignored, the center point CTR is calculated as a candidate point. However, in general, the route situation is complicated, and such an algorithm has a large error, and it is often impossible to calculate a candidate site that can be accessed by each user in as even time as possible. Therefore, when a candidate site that can be accessed in as much time as possible by each user is calculated by calculating the route status (route that each user can access and its connection), it becomes the candidate site M1. Usually, the candidate site calculated in this way is a place that is not suitable as a meeting place, that is, a place where there is no restaurant or facility. Accordingly, in the present invention, a facility / place close to the calculated candidate place is generated as a final gathering place candidate with reference to a gathering place candidate dictionary including facilities / places suitable for the meeting place. In this example, three facilities, a restaurant RES and shopping malls SP1 and SP2, are selected from the meeting place candidate dictionary (not shown) and displayed on the map. Of these three facilities, two facilities “Restaurant RES and Shopping Mall SP1” located within a predetermined distance from the candidate site M1 are selected as candidates for the meeting place. When “shopping” is selected in the genre selection, only “shopping mall SP1” is generated as the final meeting place candidate and presented to each user. Note that the meeting place candidate dictionary preferably uses various facility information (for example, display of convenience store, restaurant, business type, etc.) added to the map information. FIG. 7 is a schematic diagram, and the distance and scale of each route (road) shown in the figure are not accurate. Furthermore, in this figure, the case of gathering on foot has been described, but the candidate generation logic is basically the same for trains, buses, bicycles, cars, and the like. However, in the case of a vehicle such as a train, the moving speed, timetable, waiting time, transit time, and the like are factors of the candidate generation logic.

  Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, functions included in each member, each means, each step, etc. can be rearranged so as not to be logically contradictory, and a plurality of means, steps, etc. can be combined or divided into one. Is possible. In the embodiment, a configuration is shown in which a pseudo-meeting server that provides group communication and a navigation server that provides geographical information services such as map information are provided separately, but this is merely an example, and the function of each of these servers May be configured as a single multipoint communication management server.

It is a block diagram which shows the structure of the group communication system by this invention. It is a flowchart which shows the flow from input of search conditions to search result display and pseudo meeting display. It is a flowchart which shows the flow of a search of an additional member. It is a screen transition diagram of the mobile phone according to the present invention. It is a screen transition diagram of the mobile phone according to the present invention. It is a figure which shows the map information which tells the range which can arrive at A station within 30 minutes when a meeting place candidate is A station.
