Therefore, a unique identification code such as “P0001” or “P0002” is assigned to each of these stores 3 and restaurants 4 as a place ID. When the store 3 includes a plurality of rooms 30 in which peripheral devices are installed, a location ID is assigned to each room 30.

  The wireless access information is information necessary when the information terminal 100 connects to a peripheral device wirelessly. The wireless access information of this embodiment includes a wireless identification ID and an authentication code of peripheral devices. The wireless identification ID and the authentication code are stored in the installed device DB 217 as wireless access information in a format connected with “=”. The information terminal 100 can generate a wireless session with a peripheral device by acquiring the wireless access information. In addition, even if there are a plurality of rooms 30 in which the same peripheral device is installed as in the present embodiment, the same periphery installed in another room 30 can be managed by distinguishing and managing the wireless access information for each room 30 It is possible to prevent the device from malfunctioning.

  The billing amount is a billing amount to the user corresponding to the usage per unit time (for example, one minute) of each peripheral device. In this embodiment, the charge amount is determined according to the attributes of the peripheral devices. The attribute of the peripheral device is, for example, superiority or inferiority of the type or performance of the peripheral device. Depending on the type of peripheral device, the price of the device itself is high or low. For example, since the audio device 71 is a device that is more expensive than the microphone 72, the charge amount per unit is set to be higher for the audio device 71. Further, for example, the sound effect performance such as mixing is different depending on the model of the acoustic device 71, and the quality of the acquired image is different depending on the model of the camera 74. Therefore, in the present embodiment, the billing amount is set so that the higher the performance model, the higher the price compared to the same type of peripheral device.

  FIG. 4 shows an example in which a plurality of devices are installed at each location. However, the place ID only needs to be associated with the device ID of at least one peripheral device installed at the place indicated by the place ID.

  Hereinafter, processing executed by the CPU 101 (see FIG. 2) of the information terminal 100 when using the karaoke service in the present embodiment will be described with reference to FIG. The process shown in FIG. 5 is started when the user of the information terminal 100 inputs an instruction to download a basic application (hereinafter referred to as a basic application) necessary for executing the karaoke service from the operation unit 107 (see FIG. 2). .

  First, the CPU 101 controls the wireless communication unit 105 to connect to the application distribution server 220 via the network 10 via the wireless AP 13 or the wireless base station 5. Then, a transmission request including identification information of the information terminal 100 and information requesting transmission of the basic application is transmitted to the application distribution server 220. In response to the transmission request, the CPU 221 of the application distribution server 220 acquires a basic application from the application DB 226 (see FIG. 2) and transmits it to the information terminal 100. The CPU 101 of the information terminal 100 receives the basic application and stores it in a predetermined storage area of the nonvolatile memory 104 (S1). This completes downloading the basic app.

  Following the basic application, data necessary to determine a peripheral device (hereinafter referred to as a connection destination device) that establishes a connection state with the information terminal 100 is downloaded. Specifically, after the transmission request for the used device DB 216 and the installed device DB 217 is transmitted from the information terminal 100 to the device management server 210 in the same manner as in step S1, the used device DB 216 and the installed device DB 217 are Downloaded from the management server 210 (S2 and S3).

  When downloading of the necessary application and DB is completed in this way, the basic application stored in the nonvolatile memory 104 in step S1 is read and activated (S4). Then, for example, a message “Please read the position information from the IC tag in the room” is displayed on the display unit 106 (see FIG. 2). The user who is prompted by the message specifies the position of each room 30 from the IC tag 80 (see FIG. 1) pasted on the wall of the room 30 to the information reading unit 108 (see FIG. 2) of the information terminal 100. Read information. In the present embodiment, the IC tag 80 stores the above-mentioned place ID, that is, a unique identification code assigned to each room 30 and restaurant 4 of the store 3 as information for specifying the position of the room 30. Yes. The read place ID is stored in the RAM 103 as terminal position information indicating the position of the information terminal 100 (S5).

  Subsequently, a list of a plurality of karaoke services available on the information terminal 100 is displayed on the display unit 106. Therefore, the user can designate the karaoke service (hereinafter also simply referred to as service) that the user wants to use by operating the operation unit 107 from the list. In this embodiment, for each service, an application necessary for executing the service is determined. The correspondence relationship is stored in a predetermined storage area of the nonvolatile memory 104 when the basic application is downloaded. When the designation is accepted, the CPU 101 of the information terminal 100 identifies an application corresponding to the designated service. Hereinafter, an application that is activated on the information terminal 100 specified here is referred to as an activation application. The CPU 101 performs a process of downloading a startup application from the application distribution server 220 (S6).

  Specifically, the CPU 101 transmits to the application distribution server 220 a transmission request including a terminal ID that is identification information of the information terminal 100 and an application ID of the activated application that is information identifying the activated application. In response to the transmission request, the CPU 221 of the application distribution server 220 acquires a startup application from the application DB 226 (see FIG. 2) based on the application ID included in the transmission request, and transmits it to the information terminal 100. The CPU 101 of the information terminal 100 activates the received activation application once stored in a predetermined storage area of the nonvolatile memory 104. The subsequent processing is performed according to the activation application.

  The CPU 101 refers to the used device DB 216 (see FIG. 3) downloaded from the device management server 210 in step S2 and stored in the nonvolatile memory 104, and uses peripheral devices (hereinafter referred to as “service execution”) that are used when the service is executed by the activation application. Used device) (S7). Specifically, referring to the used device DB 216, the device ID associated with the application ID of the activated application is specified and stored in the RAM 103.

  Further, the CPU 101 refers to the installed device DB 217 (see FIG. 4) downloaded from the device management server 210 in step S3 and stored in the nonvolatile memory 104, and the location ID acquired as the terminal location information in step S5. A peripheral device (hereinafter referred to as an installed device) installed at the location indicated by is identified (S8). Specifically, with reference to the installed device DB 217, the device ID associated with the location ID acquired in step S5 is specified.

  The CPU 101 determines whether or not all the installed devices that match the used device are prepared based on the device IDs of the used device and the installed device specified in steps S7 and S8, respectively (S9). More specifically, if all the device IDs of the used devices are included in the device ID of the installed device, it is determined that all installed devices that match the used device are available (S9: YES).

  On the other hand, for example, when the location ID acquired as the terminal location information is “P0002”, the device IDs of the installed devices are “D0012”, “D0012”, and “D1203”. Not included. That is, it is determined that there are devices in use that are insufficient for the installed devices (S9: NO). Therefore, the CPU 101 displays a message indicating that the service designated by the user cannot be executed on the display unit 106 and notifies the user (S10), and ends the process shown in FIG.

  When the CPU 101 determines that all the installed devices that match the used device are available (S9: YES), the CPU 101 determines the installed device that matches the used device as the connection destination device (S11). Subsequently, the CPU 101 determines whether or not connection states have been established with all connection destination devices (S12). When there is a connection destination device that has not established a connection state (S12: NO), the CPU 101 controls the wireless communication unit 105 to generate a wireless session with the connection destination device (S13). Specifically, the CPU 101 acquires wireless access information corresponding to the device ID of the connection destination device from the installation device DB 217 (see FIG. 4). Then, a wireless session with the connection destination device is generated peer-to-peer using the wireless identification ID and authentication code of the connection destination device included in the wireless access information. Thereby, the connection state between the information terminal 100 and the connection destination device is established. The CPU 101 repeats the processes of steps S12 to S13 until the connection state can be established with all the connection destination devices.

  When connection states with all connection destination devices are established (S12: YES), the CPU 101 displays a message indicating that the connection is completed on the display unit 106 and notifies the user (S14). In addition, measurement of a connection time (session holding time) with a connection destination device is started by a timer (not shown) built in the information terminal 100.

  CPU101 performs a karaoke service according to a starting application (S15). For example, if the service provided by the activation application is “music playback service”, the CPU 101 executes the following processing. At this stage, the acoustic device 71, the microphone 72, and the display 73 (see FIG. 1) installed in the room 30 are determined as connection destination devices (S11), and the information terminal 100 and each device have already been determined. A wireless session has been generated (S12 to S14).

  First, the CPU 101 is connected to the network 10 via the wireless AP 13 or the wireless base station 5, and from the router 11 or the music distribution server 230 on the network 10, the music specified by the user by operating the operation unit 107. Download music data. Then, the connection destination device is operated by transmitting / receiving data and instructions to / from each connection destination device through a wireless session. Specifically, the CPU 101 causes the acoustic device 71 to output an accompaniment sound of the music based on the music data, and causes the display 73 to output a lyrics telop and a background image. In addition, the audio data of the singer acquired from the microphone 72 is output to the acoustic device 71. In this way, the user can enjoy karaoke using the audio equipment 71, the microphone 72, and the display 73.

  For example, if the service provided by the activation application is “moving image shooting service”, the CPU 101 uses the image data acquired from the camera 74 (see FIG. 1) and the voice data of the singer acquired from the microphone 72. A process of generating moving image data and transmitting it to the SNS server 240 via the network 10 is performed. As described above, in step S15, various services are provided to the user through the wireless session with the connection destination device determined in step S11 according to the activated application.

  While executing the service, the CPU 101 determines whether an end timing of the currently executing service has occurred (S16). In the present embodiment, when an instruction to end a service currently being executed is input via the operation unit 107 or when an instruction to execute another service is input, it is determined that an end trigger has occurred. The If such an instruction has not been input (S16: NO), the CPU 101 determines whether or not a device addition instruction has been input (S17). The device addition instruction is an instruction to add another peripheral device as a connection destination device to the connection destination device currently in the wireless session. Hereinafter, a peripheral device added as a connection destination device during service execution is referred to as an additional device.

  When a device addition instruction is given via the operation unit 107 during service execution (S17: YES), the CPU 101 controls the wireless communication unit 105 to establish a connection state with the additional device and generates a wireless session ( S18). Specifically, for example, the following processing is performed. First, a screen for inputting the wireless access information of the additional device is displayed on the display unit 106. The user operates the operation unit 107 to input the wireless identification ID and authentication code of the connection destination device of the peripheral device to be added. Based on the input information, the CPU 101 generates a new wireless session with an additional device on a peer-to-peer basis. After creating a session with the additional device, the CPU 101 returns to the process of step S15 and continues to execute the service.

  In addition, as a case where a device addition instruction | indication is made in the karaoke system 1, the following cases are assumed. For example, an application having a musical instrument function may be incorporated in a terminal device such as the information terminal 100 carried by the user. In such a case, if the terminal device is an additional device, it is possible to perform karaoke while collaborating with peripheral devices installed in the room 30 using the musical instrument function. In other words, free collaboration that is not possible with conventional karaoke systems can be realized. Therefore, in the present embodiment, if the peripheral device is wirelessly connectable, the processing is constructed so that the peripheral device desired by the user can be freely added by the device addition instruction. For example, when an additional device having a musical instrument function is connected, during the subsequent service execution, when the additional device is operated, the information terminal 100 outputs a specific sound of the musical instrument from the acoustic device 71 based on the operation information. Let

  If the above-described termination trigger occurs during service execution (S16: YES), the CPU 101 sequentially terminates the wireless session held with the connection destination device and releases the connection state with the connection destination device. (S19). Further, the measurement of the connection time (session holding time) by a timer (not shown) is terminated.

  Subsequently, the CPU 101 calculates a charging amount for the user for each connection destination device according to the connection time (session holding time) (S20). As described above, the installed device DB 217 (see FIG. 4) stores a charge amount per unit time for the use of peripheral devices. Therefore, the charge amount for use of all the connection destination devices is calculated based on the charge amount per unit time of each connection destination device and the connection time. Note that the billing amount per unit time of the peripheral device is set according to the type and performance of the peripheral device. Therefore, the information terminal 100 can determine an appropriate charge amount according to the type and performance of the connection destination device used in the used service (startup application). The calculated charge amount and the terminal ID of the information terminal 100 are transmitted via the network 10 or another network to a charge server (not shown) that performs processing for charging the user for the usage fee of the information terminal 100 (S21). ). The process shown in FIG.

  As described above, in the karaoke system 1 according to the first embodiment, the information terminal 100 uses the information reading unit 108 to locate the location where the user uses the karaoke service (the room 30 of the store 3 or the restaurant 4). Information is acquired as terminal location information. Then, the used device DB 216 is referred to, and a used device necessary for the activation application that provides the service designated by the user is determined. Furthermore, with reference to the installed device DB 217, when the installed device installed at the location indicated by the terminal position information matches the device used, the installed device is determined as the connection destination device. Then, a wireless connection state is established with the connection destination device, and the service is executed through a wireless session.

  Therefore, the information terminal 100 can dynamically establish a connection state with an appropriate peripheral device installed at a place (position) where the information terminal 100 exists, according to the activation application. For example, when a large number of people divide into a plurality of rooms 30 and perform karaoke, the user may go around the room 30 while carrying his / her information terminal 100. In this case, each time the user enters another room 30, the user can acquire position information of the room 30 and reestablish a connection state with the peripheral device. Accordingly, it is possible to avoid a malfunction that causes the peripheral devices in the room 30 other than the room 30 where the information terminal 100 is located to malfunction while ensuring freedom of movement of the user. When the user wants to change the service to be used, the user simply acquires the location information and specifies a new service (startup application) on the information terminal 100, and establishes a connection state with peripheral devices necessary for the service. be able to.

  In this way, the user downloads a desired application from the server to the information terminal 100 on demand at various locations, and connects the information terminal 100 functioning as a hub device to an appropriate peripheral device according to the application. Various services can be used. Thus, according to the information terminal 100, it is possible to realize the karaoke system 1 that is dynamic and has a higher degree of freedom than a conventional system in which a commander permanently installed in the room 30 or the like operates peripheral devices.

  In the first embodiment, the information terminal 100 corresponds to the information terminal of the present invention. The CPU 101 that acquires the location ID read by the information reading unit 108 in step S5 in FIG. 5 corresponds to the position information acquisition unit. The CPU 101 that performs the used device determination process in step S7 corresponds to a device determination unit. The nonvolatile memory 104 in which the installation device DB 217 is stored corresponds to the first storage unit. The CPU 101 that performs connection destination device determination processing in step S11 corresponds to first connection destination determination means. In step S13, the CPU 101 that controls the wireless communication unit 105 to generate a session corresponds to a connection establishment unit. Further, the CPU 101 that performs the process of determining the application corresponding to the service designated in step S6 in FIG. 5 as the start-up application corresponds to the application determining unit. The nonvolatile memory 104 in which the used device DB 216 is stored corresponds to the second storage unit. The CPU 101 that performs processing for outputting sound and images to the connection destination device in step S15 in FIG. 5 corresponds to an output control unit. The CPU 101 that performs the charge amount determination process in step S20 corresponds to the charge determination means. Each of the information terminal 100 and the device management server 210 corresponds to an information processing apparatus.

<Second embodiment>
Below, 2nd embodiment is described with reference to FIGS. The overall configuration of the karaoke system 1 shown in FIG. 1 and the configurations of the server group 200 and the information terminal 100 shown in FIG. 2 are basically the same in the second embodiment. Therefore, the description of the system and apparatus configuration is omitted (the same applies to third and fourth embodiments described later). On the other hand, in the first embodiment, almost all the processes related to the execution of the karaoke service are performed by the information terminal 100, whereas in the second embodiment, the server group 200 and the information terminal 100 are shared. More specifically, in the second embodiment, the device management server 210 performs a process for determining a device to be used corresponding to the activated app and a process for determining a connection destination device based on the used device and terminal location information. It is a feature. Below, the description of the process similar to 1st embodiment is abbreviate | omitted, and the detail of the process in 2nd embodiment is demonstrated.

  With reference to FIG. 6 and FIG. 8, the process performed by CPU101 of the information terminal 100 at the time of karaoke service utilization is demonstrated. Since the process of step S101-S104 after a process start is the same as the process of step S1, S4-S6 (refer FIG. 5) of 1st embodiment, detailed description is abbreviate | omitted.

  The CPU 101 transmits a ticket request to the device management server 210 (S105). The ticket request of the second embodiment is information for requesting the wireless access information of the connection destination device, and includes the terminal ID of the information terminal 100, the location ID that is terminal location information, and the application ID of the activation application. Although details will be described later, in the device management server 210 that has received the ticket request, if there is an appropriate peripheral device, a connection destination device is determined, and a ticket including wireless access information of the connection destination device is transmitted to the information terminal 100. . On the other hand, when there is no appropriate peripheral device, the connection destination device is not determined, and an error notification is transmitted to the information terminal 100. That is, the information terminal 100 cannot acquire a ticket (S106: NO). In this case, the CPU 101 displays a message indicating that the service designated by the user cannot be executed on the display unit 106 and notifies the user (S107), and ends the process shown in FIG.

  When the ticket transmitted from the device management server 210 is acquired (S106: YES), the CPU 101 reads information included in the ticket (S108). Although details will be described later, the ticket is signed in the device management server 210 by using the private key of the public key encryption algorithm (the private key of the device management server 210) in order to prevent tampering by a third party ( The data obtained by encrypting the hash value of the main data of the ticket with the secret key is attached). The CPU 101 of the information terminal 100 that has received the ticket confirms the authenticity of the ticket by verifying the signature with the public key of the device management server 210 distributed in advance according to the basic application. The ticket has a data structure as shown in FIG. 8, for example, and includes a location ID that is terminal location information, an application ID of a startup application, the number of connected devices, and wireless access information (that is, a wireless identification ID and an ID of each connected device). Authentication code) and ticket signature. By verifying the authenticity of the ticket and confirming that the ticket has not been tampered with, the wireless device can be correctly connected by specifying the connection destination device.

  The CPU 101 executes the karaoke service (S112) after establishing connection states with all connection destination devices (S109 to S111) in the same manner as steps S12 to S12 (see FIG. 5) of the first embodiment. The CPU 101 determines whether a device addition instruction has been input (S113). When a device addition instruction is given (S113: YES), the CPU 101 accepts designation of an additional device (S114). The receiving method is the same as the method of the first embodiment. The CPU 101 transmits a device addition request to the device management server 210 (S115). The device addition request is information requesting to reissue a ticket added with an additional device as a connection destination device, and includes the terminal ID of the information terminal 100 and the wireless access information of the additional device.

  Although details will be described later, in the device management server 210 that has received the device addition request, the ticket in which the information on the additional device is added to the previously issued ticket information is reissued and transmitted to the information terminal 100. Thereafter, the CPU 101 receives the ticket reissued by the device management server 210 (S106: YES). As with the first ticket, the CPU 101 verifies the signature of the ticket and reads information (S108). Since the information of the additional device is added to the information of the connection destination device of the ticket, the CPU 101 determines that there is a connection destination device for which the connection state has not been established (S109: NO), and wireless access of the additional device Based on the information, a wireless session is generated with the additional device (S110). Thereafter, the processing after returning to step S109 is as described above.

  When a device addition instruction is not input during service execution (S113: NO), the CPU 101 performs processing up to disconnection (S116 to S117) as in the first embodiment (S16 and S19 in FIG. 5). The connection time is transmitted to the device management server 210 together with the terminal ID (S118). The process shown in FIG.

  Processing executed by the CPU 211 of the device management server 210 will be described with reference to FIGS. The process illustrated in FIG. 7 is started when the power of the device management server 210 is turned on. First, the CPU 211 of the device management server 210 determines whether a ticket request has been received from any of the information terminals 100 connected via the network 10 (S201). When the ticket request is received (S201: YES), the CPU 211 extracts the location ID and the application ID included in the ticket request (S202). The place ID is the terminal location information of the information terminal (hereinafter referred to as the request terminal) 100 that is the transmission source of the ticket request, and the application ID is the application ID of the activation application corresponding to the service specified by the user at the request terminal 100. is there.

  The CPU 211 refers to the used device DB 216 (see FIG. 3) stored in the HDD 215 and determines a used device corresponding to the extracted application ID of the activated application (S203). Further, the CPU 211 refers to the installed device DB 217 (see FIG. 4) stored in the HDD 215 to identify the installed device installed at the location indicated by the extracted location ID (S204). The used device determination method and the installation device identification method in steps S203 to S204 are the same as steps S7 to S8 (see FIG. 5) of the first embodiment.

  The CPU 101 determines whether or not all the installed devices that match the used device are available based on the specified used device and the device ID of the installed device (S205). The determination method in step S205 is the same as that in step S9 (see FIG. 5) in the first embodiment. When there is an in-use device that is insufficient for the installed devices (S205: NO), the CPU 211 transmits to the requesting terminal 100 a service unavailability notification including information indicating that the connection destination device could not be determined (S206). The process returns to step S201.

  If the CPU 211 determines that all the installed devices that match the used device are available (S205: YES), the CPU 211 determines the installed device that matches the used device as the connection destination device (S207). Then, the request terminal 100 issues a ticket (see FIG. 8) including wireless access information necessary for establishing a connection state with the connection destination device (S208). As described above, the ticket is signed with the secret key of the public key encryption algorithm. The CPU 211 adds the terminal ID of the requesting terminal 100 and information related to the issued ticket to the issued ticket list 218 (see FIG. 9) prepared in a predetermined storage area of the RAM 213. As shown in FIG. 9, in the issued ticket list 218, the terminal ID of the requesting terminal 100, the application ID of the activation application, the device ID of the connection destination device, and the wireless access information of the connection destination device correspond to each other. Stored with. The CPU 211 transmits a ticket to the request terminal 100 (S209), and returns to the process of step S201.

  When the ticket request has not been received (S201: NO), the CPU 211 determines whether or not the connection time has been received from any of the information terminals 100 connected via the network 10 (S210). When the connection time is received (S210: YES), the CPU 211 refers to the issued ticket list 218 (see FIG. 9) and the installation device DB 217 (see FIG. 4) in the RAM 103, and the information terminal 100 that is the transmission source of the connection time. The charge amount for the user is calculated (S211). The billing amount calculation method is the same as that in step S20 in the first embodiment. Then, the CPU 211 transmits the terminal ID of the information terminal 100 that has transmitted the calculated charging amount and connection time to a charging server (not shown) (S212). Further, the information related to the information terminal 100 that is the transmission source of the connection time is deleted from the issued ticket list 218, and the process returns to step S201.

  When the connection time is not received (S210: NO), the CPU 211 determines whether a device addition request is received from any of the information terminals 100 connected via the network 10 (S213). When the device addition request is received (S213: YES), the CPU 211 reissues the ticket based on the issued ticket list 218 (see FIG. 9) in the RAM 103 and information included in the device addition request (S214). Specifically, information on the issued ticket specified by the terminal ID included in the device addition request is read from the issued ticket list 218, and the wireless access information of the additional device included in the device addition request is added. And reissue the ticket. The reissued ticket is also signed with the private key, just like a normal ticket. The CPU 211 transmits the reissued ticket to the information terminal 100 that is the transmission source of the device addition request (S215), and returns to the process of step S201.

  When the device addition request has not been received (S213: NO), the CPU 211 determines whether or not a process end instruction has been input (S216). If an end instruction has not been input (S216: NO), the CPU 211 returns to the process of step S201. If an end instruction is input (S216: YES), the CPU 211 ends the process shown in FIG.

  As described above, in the karaoke system 1 of the second embodiment, the information terminal 100 acquires terminal position information by the information reading unit 108. Then, a request for a ticket including terminal location information (location ID) and an application ID of an activation application that provides a service specified by the user of the information terminal 100 is transmitted to the device management server 210. The device management server 210 refers to the used device DB 216 to determine a used device necessary for the activation application. The device management server 210 further refers to the installed device DB 217 and determines that the installed device is the connection destination device when the installed device installed at the location indicated by the terminal location information matches the device used. Then, a ticket including wireless access information necessary for establishing a wireless connection state with the connection destination device is transmitted to the information terminal 100. The information terminal 100 establishes a wireless connection state with the connection destination device based on the ticket information, and executes the service through a wireless session.

  As described above, in the second embodiment, as in the first embodiment, the information terminal 100 is connected to an appropriate peripheral device installed in a place (position) where the information terminal 100 exists, according to the activation application. The connection state can be established dynamically.

  In the second embodiment, the information terminal 100 corresponds to the information terminal of the present invention, and the device management server 210 corresponds to the server of the present invention. The CPU 211 that acquires the location ID from the information terminal 100 in step S202 in FIG. 7 corresponds to the terminal information acquisition unit. The CPU 211 that performs the used device determination process in step S203 in FIG. 7 corresponds to a device determination unit. The HDD 215 storing the installation device DB 217 corresponds to the first storage unit. The CPU 211 that performs the connection destination device determination process in step S207 corresponds to a fourth connection destination determination unit. The CPU 211 that performs the process of transmitting the ticket to the information terminal 100 in step S209 corresponds to a connection destination notification unit.

<Third embodiment>
Hereinafter, the third embodiment will be described with reference to FIGS. 10 and 11. In the third embodiment, as in the second embodiment, the processing related to the karaoke service execution is performed by the server group 200 and the information terminal 100, but only a part of the shared content is different. Therefore, in the following, details of the processing different from the second embodiment will be described while omitting the description of the same processing as in the second embodiment. In FIG. 10 and FIG. 11, steps in which the same processing as the processing of the second embodiment (see FIG. 6 and FIG. 7) is performed are assigned the same step number.

  First, with reference to FIG. 10, the process performed by CPU101 of the information terminal 100 at the time of karaoke service utilization is demonstrated. In the third embodiment, unlike the second embodiment, the information terminal 100 determines the device used and the connection destination device.

  First, after the basic application is downloaded (S101), the used device DB 216 (see FIG. 3) is downloaded to the information terminal 100 (S131). The method is the same as step S2 of the first embodiment (see FIG. 5). Similar to the second embodiment, the processes of steps S102 to S104 are performed. Subsequently, a use device corresponding to the activated application is determined (S132). The method for determining the device to be used is the same as step S7 (see FIG. 5) of the first embodiment.

  Subsequently, the CPU 101 transmits a ticket request to the device management server 210 (S133). The ticket request according to the third embodiment is information for requesting information on an installed device at a location where the information terminal 100 exists, and includes a terminal ID of the information terminal 100 and a location ID that is terminal location information. Thereafter, when a ticket is acquired from the device management server 210 (S134), the CPU 101 reads the ticket information (S135). Although details will be described later, the ticket includes the device ID of the installed device in the place where the information terminal 100 exists. Therefore, the CPU 101 has all the peripheral devices that match the device in use at the location where the information terminal 100 exists based on the device ID and the device ID of the device used that is determined in step S132 and stored in the RAM 103. It is determined whether or not (S136). The determination method here is the same as step S9 (see FIG. 5) of the first embodiment.

  If all the installed devices that match the devices used are not available (S136: NO), the CPU 101 displays a message indicating that the service cannot be executed on the display unit 106 and notifies the user (S137), and performs the processing shown in FIG. finish. If all the installed devices that match the used device are available (S136: YES), the CPU 101 determines the installed device that matches the used device as the connection destination device (S138). Subsequent connection state establishment processing and karaoke service execution processing (S109 to S112) are the same as in the second embodiment.

  In the second embodiment, if there is an instruction to add a device during service execution, processing for connecting to the additional device is performed (see steps S113 to S115 in FIG. 6), but this processing is performed as in the third embodiment. May be omitted. In the second embodiment, after a service termination trigger occurs (S116: YES), the connection time with the connection destination device is released (S117), and then the connection time is transmitted to the device management server 210 for calculating the billing amount. However, this process may be omitted as in the third embodiment (see step S118 in FIG. 6). In this case, the billing amount may be calculated by another arbitrary method.

  Processing executed by the CPU 211 of the device management server 210 will be described with reference to FIG. When a ticket request is received from any one of the information terminals 100 (S201: YES), the CPU 211 extracts a location ID included in the received ticket request (S231). Then, referring to the installed device DB 217 (see FIG. 4) of the HDD 215, the installed device in the location indicated by the location ID, that is, the location where the information terminal 100 that is the transmission source of the ticket request exists is identified (S232). A ticket including information on the installed device is issued (S233). Although illustration is omitted, the ticket of the third embodiment includes, for example, a location ID, an application ID, the number of installed devices, a device ID of each installed device, and wireless access information. The device ID of each installed device is information necessary for the information terminal 100 to determine a connection destination device.

  After transmitting the ticket (S209), the CPU 211 returns to the process of step S201, and when an end instruction is input (S216: YES), the process of FIG. 11 ends. In the present embodiment, as described above, the device addition and billing amount calculation processing is omitted, and therefore the processing shown in FIG. 11 does not include the processing in steps S210 to S215 of the second embodiment. .

  As described above, in the karaoke system 1 of the third embodiment, the information terminal 100 acquires terminal position information by the information reading unit 108. Further, the used device corresponding to the activated application is determined with reference to the used device DB 216. Then, a ticket request including terminal location information (location ID) is transmitted to the device management server 210. The device management server 210 refers to the installed device DB 217 and identifies the installed device installed at the location indicated by the terminal position information. Then, a ticket including information regarding the specified installed device is transmitted to the information terminal 100. The information terminal 100 determines a connection destination device based on information on the device used and the installed device included in the received ticket. Then, a wireless connection state is established with the connection destination device, and the service is executed through a wireless session.

  As described above, in the third embodiment, as in the first embodiment, the information terminal 100 is connected to an appropriate peripheral device installed in a place (position) where the information terminal 100 exists, according to the activation application. The connection state can be established dynamically.

  In the third embodiment, the information terminal 100 corresponds to the information terminal of the present invention. The CPU 101 that acquires the location ID read by the information reading unit 108 in step S103 in FIG. 10 corresponds to the position information acquisition unit. The CPU 101 that performs the used device determination process in step S132 corresponds to a device determination unit. The CPU 101 that transmits the ticket request by controlling the wireless communication unit 105 in step S133 corresponds to the first transmission unit. The CPU 101 that obtains the ticket in step S134 corresponds to the first receiving unit. The CPU 101 that performs connection destination device determination processing in step S138 corresponds to second connection destination determination means. In step S110, the CPU 101 that controls the wireless communication unit 105 to generate a session corresponds to a connection establishment unit.

<Fourth embodiment>
Hereinafter, a fourth embodiment will be described with reference to FIGS. 12 and 13. In the fourth embodiment as well, as in the second embodiment, the processing related to the karaoke service execution is performed by the server group 200 and the information terminal 100, but only a part of the shared content is different. Therefore, in the following, details of the processing different from the second embodiment will be described while omitting the description of the same processing as in the second embodiment. In FIG. 12 and FIG. 13, the same step number is assigned to the step in which the same process as the process of the second embodiment (see FIG. 6 and FIG. 7) is performed.

  First, a process executed by the CPU 101 of the information terminal 100 when using the karaoke service will be described with reference to FIG. In the fourth embodiment, unlike the second embodiment, the connection destination device is determined by the information terminal 100.

  First, after the basic application is downloaded (S101), the installation device DB 217 (see FIG. 4) is downloaded to the information terminal 100 (S151). The method is the same as step S3 (refer FIG. 5) of 1st embodiment. Similar to the second embodiment, the processes of steps S102 to S104 are performed.

  Subsequently, the CPU 101 transmits a ticket request to the device management server 210 (S152). The ticket request of the fourth embodiment is information for requesting information on a device used corresponding to the activation application, and includes the terminal ID of the information terminal 100 and the application ID of the activation application. Thereafter, when a ticket is acquired from the device management server 210 (S153), the CPU 101 reads ticket information (S154). Although details will be described later, the ticket includes the device ID of the device used corresponding to the activation application. Therefore, the CPU 101 refers to the installed device DB 217 to determine whether or not all peripheral devices that match the device in use are available at the location where the information terminal 100 exists (S155). The determination method here is the same as step S9 (see FIG. 5) of the first embodiment.

  If all the installed devices that match the devices used are not available (S155: NO), the CPU 101 displays a message indicating that the service cannot be executed on the display unit 106 and notifies the user (S156), and performs the processing shown in FIG. finish. If all the installed devices that match the used device are available (S155: YES), the CPU 101 determines the installed device that matches the used device as the connection destination device (S157). Subsequent connection state establishment processing, karaoke service execution processing (S109 to S112), and processing end processing (S116 to S117) are the same as in the second embodiment.

  Processing executed by the CPU 211 of the device management server 210 will be described with reference to FIG. When the ticket request is received from any one of the information terminals 100 (S201: YES), the CPU 211 extracts the application ID of the activation application included in the received ticket request (S251). Then, referring to the used device DB 216 (see FIG. 3) of the HDD 215, the used device used by the activation application indicated by the application ID is determined (S252), and a ticket including information on the used device is issued (S253). . Although illustration is omitted, the ticket of the fourth embodiment includes, for example, an application ID and a device ID of the device used. After transmitting the ticket (S254), the CPU 211 returns to the process of step S201, and when an end instruction is input (S216: YES), the process of FIG. 13 ends.

  As described above, in the karaoke system 1 of the fourth embodiment, the information terminal 100 acquires terminal position information by the information reading unit 108. After downloading the installed device DB 217 and the startup application, a ticket request including the application ID of the startup application is transmitted to the device management server 210. The device management server 210 refers to the used device DB 216 and determines a used device corresponding to the activated application. And the ticket containing the information regarding a use device is transmitted with respect to the information terminal 100. FIG. The information terminal 100 determines a connection destination device based on the information on the used device included in the received ticket and the information on the downloaded installed device DB. Then, a wireless connection state is established with the connection destination device, and the service is executed through a wireless session.

  As described above, in the fourth embodiment as well, as in the first embodiment, the information terminal 100 is connected to an appropriate peripheral device installed at a location (position) where the information terminal 100 exists, according to the activation application. The connection state can be established dynamically.

  In the fourth embodiment, the information terminal 100 corresponds to the information terminal of the present invention. The CPU 101 that acquires the location ID read by the information reading unit 108 in step S103 in FIG. 12 corresponds to a position information acquisition unit. The CPU 101 that transmits the ticket request by controlling the wireless communication unit 105 in step S153 corresponds to a second transmission unit. The CPU 101 that obtains the ticket in step S153 corresponds to the second receiving unit. The CPU 101 that performs the connection destination device determination process in step S157 corresponds to a third connection destination determination unit. The nonvolatile memory 104 that stores the installation device DB 217 corresponds to the first storage unit. In step S110, the CPU 101 that controls the wireless communication unit 105 to generate a session corresponds to a connection establishment unit.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the embodiment, the processing of the information terminal 100 has been described by taking the case where the karaoke service is used as an example, but the present invention is also applicable to other systems. For example, the process described in the embodiment is a process in which the information terminal establishes a connection state with a microphone, an audio device, and a projector installed in the vicinity of the position when the startup application is an application that executes a presentation. Applicable.

  As shown in FIG. 2, in the above-described embodiment, the server group 200 includes four servers 210 to 240. However, in the cloud system, the server group 200 is regarded as one computer. Therefore, the processes performed in any of the servers 210 to 240 can be collectively regarded as a process in one server. Note that the server group 200 may actually be configured as one server, all the databases such as the used device DB 216 and the installed device DB 217 are stored in the storage device of the server, and the CPU of the server may perform all the processing. Needless to say.

  In the embodiment, the example in which the same peripheral device is installed in the room 30 illustrated in FIG. 1 has been described, but different types of peripheral devices may be installed in each room 30. In addition, as an example of a method for the information terminal 100 to acquire terminal position information, an IC tag 80 storing a place ID is installed in a karaoke facility, and the information reading unit 108 (non-contact IC reader) removes the place from the IC tag 80. An example of reading the ID is given. However, any other method may be adopted. For example, a method of reading bar code or two-dimensional code information or visible light communication may be used. Further, when the information terminal 100 enters the room 30, a process of automatically acquiring GPS information (latitude, longitude, altitude) may be performed. In this case, the installation device DB 217 (see FIG. 4) stores specific ranges of latitude, longitude, and altitude in association with the location ID. Then, the information terminal 100 or the device management server 210 may specify the installed device based on the location ID corresponding to the range to which the latitude, longitude, and altitude of the information terminal 100 belong.

  In the processing in the information terminal 100 shown in FIG. 5 and the like, the basic application, the used device DB 216, and the installed device DB 217 are not necessarily downloaded at this timing. The basic application, the used device DB 216, and the installed device DB 217 may be downloaded in advance and stored in the nonvolatile memory 104. In this case, the process shown in FIG. 5 and the like may be started when the basic application stored in the nonvolatile memory 104 is activated.

  When the used device is determined, the used device DB 216 that stores a plurality of karaoke service applications and the used devices in association with each other is not necessarily used. In this case, for example, the minimum peripheral devices (for example, the audio equipment 71, the microphone 72, and the display 73) that are used in karaoke may be determined uniformly as the devices to be used without particularly distinguishing services. Further, when the use device DB 216 or the installation device DB 217 is used in the information terminal 100, the database does not necessarily need to be stored in the built-in nonvolatile memory 104. For example, processing may be performed using what is stored in an external memory such as a memory card.

  In the processing of the first and second embodiments, as in the third and fourth embodiments, at least one of the device addition processing and the processing related to the calculation of the charge amount may be omitted. On the contrary, in the processes of the third and fourth embodiments, as in the first and second embodiments, at least one of a device addition process and a process related to calculation of a charge amount may be added. Further, the billing amount may be calculated based only on the attribute of the connection destination device regardless of the connection time.
