Description

  The present invention uses a PoC (Push-to-talk over Cellular) possessed by a mobile communication terminal to explain a browsing object and provide a communication system using the PoC applicable to providing information on the browsing object and the communication thereof. The present invention relates to a method and a parent device terminal.

  Conventionally, in an exhibition facility such as a museum, an explanation panel and an audio guide device are provided in the vicinity of the exhibit to explain the exhibit. Therefore, if a visitor wants to ask a question about an exhibit, an instructor can be called depending on the facility.

  However, when the floor is crowded, it is often difficult to call an accountant residing on that floor.

  Even if an intercom is provided near the exhibit, it takes time for the instructor to move and is inefficient.

  Therefore, as a case of individually responding to a question, an exhibit data providing system using a non-contact IC tag and a portable terminal that can be used in a venue where the exhibit is installed is disclosed (Patent Document 1). : Japanese Patent Laid-Open No. 2002-259611).

  In this method, a non-contact IC tag is issued in advance to a viewer who enters the venue, and a portable terminal that can be used in the venue is lent.

  When the detailed data of the exhibit in the venue is desired, the reader holds the non-contact IC tag over the non-contact IC reader / writer installed near the exhibit.

  As a result, the contactless IC reader / writer receives the identification information of the contactless IC tag and simultaneously transmits detailed data to the portable terminal held by the viewer holding the contactless IC tag.

  Thereby, the viewer can acquire detailed data.

  Also, there is an explanation support method in which a server manages information on a portable terminal owned by a user who requests explanation of a specific product or service, and a mobile terminal possessed by an instructor who can explain the product or the service. It is disclosed (see Patent Document 2: Japanese Patent Laid-Open No. 2003-11150).

  For example, a user who enters the store can request an explanation of the product in the store using a wireless communication terminal lent by a salesperson.

  First, when a user requests a specific product description from a server via a wireless communication terminal, the server learns for each explainer the explainer information registered in the HDD (Hard Disk Drive) in the server. The most appropriate explainer is selected using the information of the product knowledge.

  Next, the server establishes voice communication and video communication between the user's wireless communication terminal and an optimal presenter.

  Accordingly, the user can use the mobile communication terminal to ask a question about a specific product to the best explainer of the product.

  In this way, the user can receive explanations individually from the explanation staff, but as a service to receive explanations in the same way, users can ask questions using PoC in order to obtain specific information An information guidance providing apparatus and an information guidance service method used therefor are disclosed (see Japanese Patent Application Laid-Open No. 2006-17749).

  Here, PoC is like a walkie-talkie using IP (Internet Protocol), and the call is one-way. In addition, PoC is capable of grouping speaking parties as in IM (Instant Messaging), and can view the state of the other party.

  Therefore, in PoC, a call can be made by selecting a partner (one person or a group) who is in a call ready state and pressing the call button.

  In other words, PoC is a cellular phone transceiver mode, and it is not necessary to dial the number of the called party, and the time until connection is short, so that a call can be made simultaneously with a plurality of called parties.

  First, the user terminal in this patent document 3 communicates with the information guidance providing device by PoC by connecting to the PoC server. This information guidance providing device provides train terminal time information and transfer information guidance to a user terminal. Furthermore, it has a voice recognition unit for recognizing voice information received from the user terminal and a synthesized voice function for creating answer information by voice.

  The user asks a question for requesting information via the user terminal.

  Here, the information guidance providing apparatus analyzes the voice uttered by the user by the voice recognition apparatus, creates answer information for the question information based on the analysis result, and uses PoC for the user terminal. Reply. This is characterized in that a question and an answer are obtained in real time about the train transfer route.

  However, in the configuration shown in Patent Document 1 and Patent Document 3, predetermined information is transmitted to the questioner according to the question content of the questioner by registering predetermined information. .

  For this reason, when a questioner has various questions, it is difficult to completely eliminate the question with only mechanical answer information.

  Furthermore, in Patent Document 2 described above, the user can receive explanations from the best presenter. However, the number of instructors is insufficient in situations where a large number of questioners can occur, such as an exhibition hall. there's a possibility that.

  In such a case, if an individual instructor tries to respond to a plurality of questioners, the explanation of the instructor and the questions of the visitors may be made at the same time by using a simultaneous call between multiple people of a normal mobile communication terminal. , Which can lead to confusion.

  The present invention has been made in view of the above circumstances, and an object of the present invention is, for example, communication that enables connection between a visitor who wants to ask a question and a terminal of an explanatory staff by PoC communication without confusion. It is to provide a system, its communication method, and a master terminal.

  FIG. 9 is a sequence diagram illustrating processing for performing PoC communication in the communication system according to the embodiment of this invention.

  In the PoC phone book 26 of the parent device 70 of FIG. 4, the establishment information of the second child device 60 that is a terminal carried by the instructor and the first child device 40 (child device) received from the reception terminal 50 In the state where the establishment information such as the phone number of 40a) is registered, the control unit 101 of the base unit 70 displays the PoC phone in the display operation unit 72 in the “PoC phonebook mode” shown in FIG. The book 26 is displayed.

  In addition, when the registration name is included in the establishment information 16 of each first handset 40, the registration name is preferentially displayed. In addition, the “PoC phone book mode” in FIG. 8A and the “PoC communication status mode” in FIG. 8B are displayed as shown in FIG. 8 so that the display contents can be switched by visitors at any time. A display switching button may be provided, or both contents may be simultaneously displayed on one screen.

  First, for example, when the visitor A wants to perform PoC communication in order to receive an explanation about the exhibit B, from the display content of the “PoC phone book mode” of the display operation unit 72 of the master unit 70b for the exhibit B, The registered name corresponding to the visitor A is selected, and the PoC button 115 (FIG. 4) called “call” in FIG. 8A is pressed (step 91).

  The session management unit 112 (FIG. 4) of the control unit 101 of the main unit 70b for exhibit B searches the PoC telephone directory 26 in the memory 105, and the first slave unit 40a corresponding to the registered name, and this exhibit The second slave unit 60b in which the subscription information 15 is registered in the PoC telephone directory 26 is designated as an explanation for B, and a session establishment is requested to the PoC server 10 (step 92).

  The PoC server 10 generates a session ID to be assigned to the designated first child device 40a and second child device 60b (step 93).

  The PoC server 10 transmits a session ID to each of the exhibit B master device 70b, the second slave device 60b, and the first slave device 40a, and requests session establishment (step 94, step 97, step 100). ).

  Receiving the session ID information, each first handset 40a stores the session ID (step 95, step 98, step 101) and returns a session establishment response signal (step 96, step 99, step 102). ).

  As a result, a talk session is established between the exhibit B master device 70b, the second slave device 60b, and the first slave device 40a (step 103).

  In this way, when a talk session is established between the first slave unit 40a and the second slave unit 60b, the terminal holders of the first slave unit 40a and the second slave unit 60b are mutually connected. When a person who has acquired the right to speak by pressing the PoC button 115 speaks, the visitor A can start a call with the instructor B for the exhibit B using the first handset 40a. .

  When a talk session is established between the visitor A and the instructor B, the control unit 101 of the exhibit B master unit 70b displays a display indicating that the “PoC communication status mode” is displayed on the display operation unit 72. Do.

  In the “PoC communication status mode” in FIG. 8B, the current speaker (in this case, Uchida), the current participants in the PoC communication related to the exhibit A, and the participation status are displayed.

  For example, the instructor (the instructor portable terminal) registers the first slave unit 40 that has requested establishment of PoC communication, but each parent unit 70 (which is a parent unit of PoC communication) by executing the flow shown in FIG. 70a, 70b, and 70c), all the registration data of the first handset 40 possessed by the visitors (for example, Uchida, Kawashima, Sugimoto in the drawing) is registered. The display operation unit 72 in the “PoC communication status mode” of each parent device 70 displays the PoC communication status as shown in FIG.

  In addition, a similar screen can be displayed on the display unit 108 of each first handset 40 participating in the PoC communication. However, in order to display on the limited display unit 108, the number of visitors can be increased or decreased. You may adjust the number of people displayed so that the displayed content matches. Here, the case where the external device 71 is connected to the parent device 70 has been described. However, in FIG. 4, when the external device 71 is not connected, the control unit 101 of the parent device 70 is not connected to the display operation unit 72. Instead, the display content described above can be displayed on the display unit 108.

  In FIG. 9 again, in the PoC communication status column of the display operation unit 72 of the main unit 70b for exhibit B in the “PoC communication status mode”, as shown in FIG. The other visitors who are viewing and viewing the exhibit B can check the current question status on the display operation unit 72 of the master unit 70b for the exhibit B.

  Further, at this time, as another visitor, if the visitor B having the terminal 100 (first child device 40b) wants to ask a question regarding the exhibit B, the visitor B establishes the communication establishment described above. Similarly to the processing, the registered name of the visitor B in the PoC telephone directory displayed on the display operation unit 72 of the exhibit B master device 70b is selected and pressed (step 104).

  Thereafter, by pressing the PoC button 115 (call button), the session management unit 112 of the control unit 101 of the main unit 70b for exhibit B requests the PoC server 10 to establish a session for the first slave unit 40b. (Step 105). The PoC server 10 generates a session ID to be assigned to the first child device 40b (step 106) and transmits this session ID to the first child device 40b (step 107).

  Upon receiving the session ID information, the first handset 40b stores the session ID (step 108) and returns a session establishment response signal to the PoC server 10 (step 109).

  This establishes PoC communication among the second slave unit 60b, the exhibit B master unit 70b, the first slave unit 40a, and the first slave unit 40b (step 110).

  Thereafter, when the questions and answers by the instructor and the visitors are completed, the exhibit B master device 70b disconnects the PoC communication.

  In addition, even after the PoC communication is completed, since the used session ID, the call history, and the call partner information remain in the first slave unit 40 (40a, 40b), by pressing the PoC button 115, It is possible to start a call with the second slave device 60b, the exhibit B master device 70b, the first slave device 40a, and the first slave device 40b.

  As described above, with the communication system, the communication method, and the master terminal according to the first embodiment of the present invention, it is possible to ask a specific inquirer about a specific exhibit while there are many visitors. It becomes.

  In addition, other visitors can participate, and explanation staff can give explanations to multiple visitors at the same time, preventing confusion when multiple people ask questions at the same time. .

  Next, a modification of the communication system according to the embodiment of the present invention will be described with reference to FIG.

  The receiving terminal 50, the first handset 40, and the second handset 60 used in the communication system of the modification are all the same as each terminal used in the embodiment of the present invention.

  However, the parent device 70 is characterized in that it is possible to arbitrarily select the explanation staff and the first child device.

  FIG. 10 is an image diagram illustrating an example of a screen displayed on the display operation unit 72 of the parent device 70 in the modified example. FIG. 10A shows “PoC phonebook mode”, and FIG. 10B shows “PoC”. "Communication status mode".

  In the first embodiment of the present invention, when performing PoC communication, a visitor selects only his / her terminal as a terminal used for PoC communication. However, in the communication system according to the modified example, a visitor performs PoC communication. When starting, it is possible to select not only the terminal itself but also the other first handset from the beginning.

  Also, as shown in FIG. 10 (a), a plurality of instructors are also waiting, and a transmission button 16 for selecting a desired instructor from the plurality of instructors and transmitting the information is provided in the master unit 70. Are displayed on the display operation unit 72.

  As a result, the attendee selects a desired explanation staff, selects a registered name indicating the visitor to be called, and presses a “send” button 115 corresponding to each of the registered names. Can be set. As in the first embodiment, the “PoC phonebook mode” in FIG. 10A and the “PoC communication status mode” in FIG. 10B are displayed by the visitors as needed. As shown in FIG. 10, a display switching button may be provided so as to be switched, or both contents may be simultaneously displayed on one screen.

  Therefore, it is possible for visitors to set up an optimal group of multiple participants, and to increase the chances of receiving more detailed explanations according to various situations such as when visiting in groups. . Next, a communication system according to the second embodiment of this invention will be described with reference to FIG.

  FIG. 11 is a block diagram showing an overall configuration of a communication system according to the second embodiment of this invention. In the communication system of the second embodiment, the web server unit 24 included in the PoC server group 20 includes an HTML-format network phone book 25 and a network phone book management means (not shown). Updates the information registered in the network telephone directory 25 based on the subscription information 15 transmitted from the reception terminal 50 as needed.

  The web server unit 24 can obtain information necessary for PoC communication in an HTML format by allowing the terminal 100 that performs PoC communication to access the web server unit 24 via the network 30.

  Here, the base unit 70 acquires the update information of the network phone book 25 by accessing the web server 24 at any time and inquiring about the update status. The PoC phone book 26 of the parent device 70 obtains this update information and updates it as needed, so that it can support a large number of terminals 100 that use PoC communication. For this reason, first, the flow of the first handset 40 joining the communication system will be described with reference to FIGS.

  The network phone book 25 is obtained by storing the establishment data 16 of the terminal 100 using the PoC communication in the HTML format on the web server 24, and can be accessed only by a terminal that has authenticated and authorized the terminal 100 to be used. It is a lot of data.

  In the communication system according to the second embodiment of the present invention, only the parent device 70 can be accessed by making an inquiry to the web server unit 24.

  FIG. 12 is a flowchart showing a process of registering the visitor A in the PoC phone book 26 of the parent devices 70a, 70b, 70c.

  First, in order to use the communication system according to the second embodiment of the present invention, the first handset 40a held by the visitor A notifies the reception terminal 50 including the subscription information 15 by e-mail (step). 121).

  Upon receiving the subscription information 15 from the first handset 40a, the reception terminal 50 creates the establishment information 16 necessary for PoC communication (step 122) and transmits it to the web server unit 24 by e-mail (step 123).

  The web server unit 24 that has received the establishment information 16 registers the first slave unit 40a in the network telephone directory 25 in the web server unit 24 (step 124).

  In addition, the control unit 101 (inquiry means) of the base unit 70 uses a timer (not shown) to check the presence or absence of the first handset 40a that has joined or withdrawn from the communication system at regular intervals. Update information confirmation information for confirming the update status of the network telephone directory 25 in the unit 24 is generated and transmitted from the wireless communication unit 103 to the web server unit 24 via the network 30 (step 125).

  Upon receiving the update status confirmation information, the network telephone directory management means (not shown) of the web server unit 24 notifies the inquired base unit 70 as the update information of the current update status (step 126). Subsequently, the reception terminal 50 is notified that the registration of the first slave unit 40a has been completed (step 127).

  Here, the PoC phone book management means (not shown) included in the control unit 101 of the parent device 70 updates the update information. 11), each parent device 70 (parent devices 70a, 70b, 70c) that has received the update information adds the first child device 40a to each PoC phone book 26. (Step 128).

  After that, by selecting the registered name of the first handset 40a in the PoC phone book 26 displayed on the display operation unit 72 of the external device 71 of the base unit 70, the base unit 70 is previously set in the base unit 70. A session is established with the second handset 60 registered in the. Since this flow is the same as the processing for performing PoC communication according to the first embodiment of the present invention, a description thereof will be omitted.

  As described above, the communication system, communication method, and parent device terminal according to the second embodiment of the present invention can cope with an increase in the number of first child devices by using the network telephone directory 25. .

  That is, it is possible to reduce the load on the memory due to the increase in the data amount of the memory 105 of the terminal 100 in which the PoC phone book 26 is registered.

  Next, a communication system according to the third embodiment of this invention will be described.

  In the communication system according to the third embodiment, by creating various categories from the subscription information 15 of the first slave unit 40 received by the reception terminal 50, a plurality of first slave units 40 are sorted and grouped. I do. The communication system services are differentiated according to the group type.

  For example, here, the base unit 70 performs grouping for each time zone visited based on the information on the date and time of arrival included in the subscription information 15 of the first handset 40, and the communication system of the communication system according to the time zone. A case where the provision is limited will be described with reference to FIGS.

  FIG. 13 is a diagram showing a time zone in which the time from the opening time to the closing time of the exhibition facility is further divided.

  Here, the opening hours from 9 am to 12 noon are referred to as time zone A, from 12 noon to 3 pm as time zone B, and from 3 pm to 6 pm as closing time zone as time zone C. .

  The reception terminal 50 transmits the establishment information 16 created based on the subscription information 15 to the parent device 70 via the network 30. The establishment information 16 is transmitted from the first child device 40a to the first child device 40c. Contains information about each visit date and time. Here, for example, the first slave unit 40a transmits the subscription information 15 to the reception terminal 50 at 9 am, the first slave unit 40b at 13:00 pm, and the first slave unit 40c at 16:00 pm. To do.

  First, when the classification unit (not shown) of the control unit 101 of the parent device 70 creates the PoC phone book 26 based on the establishment information 16 received from the reception terminal 50, based on the visit date information included in the establishment information 16, The first slave unit 40a is classified by time zone A, the first slave unit 40b is classified by time zone B, and the first slave unit c is classified by time zone C, respectively.

  Then, base unit 70 compares the current time zone with the group to which the first handset 40 that permits PoC communication in this time zone belongs.

  In the third embodiment of the communication system of the present invention, the time period in which the first slave unit 40 can perform PoC communication with the second slave unit 60 is limited, and the communication system can be used. The first handset 40 belonging to a group not included in the time zone cannot use the communication system.

  That is, the parent device 70 does not display the registered name corresponding to the first child device 40 that is determined to have exceeded the expiration date for which the communication system can be used, on the display operation unit 72 of the parent device 70.

  For example, it is assumed that a visitor B who came at 13:00 looks at the display operation unit 72 of the base unit 70 to perform PoC communication using the first handset 40b carried at 16:00. However, since the time zone C is a time zone that is different from the time zone B to which the first handset 40b belongs, the display of the own terminal cannot be found.

  For this reason, the communication system according to the third embodiment of the present invention cannot be received.

  The control unit 101 (selecting means) of the parent device 70 performs group selection for each time zone based on the flowchart shown in FIG. 11, for example, and performs display / non-display processing.

  FIG. 14 is a flowchart showing a process for determining whether or not the PoC communication of the first handset 40 grouped by time period is possible.

  First, the control unit 101 of the parent device 70 confirms whether the current time zone is A (step 141).

  In the case of time zone A, the control unit 101 of the base unit 70 displays all registered names in which the visit date and time information is included in the time zone A in the establishment information 16 currently recorded in the memory 105. This is displayed on the unit 72 (step 141).

  If it is not time zone A, it is confirmed whether it is time zone B (step 142). If it is not the time zone B, the control unit 101 determines that the current time zone is C, and displays the registered names of the groups belonging to the time zone C on the display operation unit 72 (step 143).

  If it is time zone B, the registered name of the group belonging to time zone B is displayed on display operation unit 72 (step 145).

  In this way, since the first handset 40 whose registered name is not displayed because it does not belong to the predetermined time zone cannot establish PoC communication, the visitor uses the communication system. It is possible to feel that it is necessary to browse the exhibits within the time limit, and as a result, it is possible to smoothly move the visitors in the hall.

  In addition to restricting the first slave unit 40 displayed on the display operation unit 72 of the master unit 70 by filtering with various information included in the subscription information 15, the subscription information of the first terminal 40 is also included. 15, it is also possible to provide an explanation in line with the characteristics of the visitors.

  For example, by using information such as the date of birth included in the subscription information 15 included in the establishment information 16, it is possible to read the age group of the visitors. As a result, while a plurality of instructors are waiting according to the age of the visitors, the instructors who can explain optimally are extracted, and the second handset 60 (60a) carried by this instructor is extracted. , 60b, 60c).

  As described above, in the communication system according to the third embodiment of the present invention, the service is specialized by grouping the first slave units 40 based on the subscription information 15 or the establishment information 16. Thus, it becomes possible to provide more detailed services such as limitation of the service time zone and allocation of the second handset 60.
