First connection establishment means for establishing a connection with the first portable terminal, and call request information for recruiting other users who share the use of the room after the first connection detection means detects a connection. A second SSID transmission means for broadcast transmission of the second SSID in a non-security state; A second display means for receiving and displaying the second SSID broadcasted by the second SSID transmission means and a connection from the second portable terminal receiving the second SSID broadcasted by the second SSID transmission means are detected. A second connection detecting unit configured to establish a connection with the second portable terminal that further receives the common SSID broadcast-transmitted by the common SSID transmitting unit after the second connection detecting unit detects a connection. 2 connection establishment means.

  The karaoke store has, for example, a POS terminal or a karaoke device installed in each room at a reception counter in the karaoke store. Further, the POS terminal of the karaoke store and the karaoke apparatus installed in each room are connected by wired LAN by wired communication, and the POS terminal or the karaoke apparatus installed in each room can be connected by wireless communication to a portable terminal such as a smartphone via wireless LAN. It has become.

  In addition, the karaoke apparatus includes performance means for outputting karaoke music, login means for reserving music after user login, and idle state detection means for detecting an idle state in which the karaoke apparatus is not performing and is not logged in.

  In this wireless LAN, the idle state detection means is in an idle state, that is, a karaoke device is installed for a plurality of portable terminals including one first portable terminal and at least one second portable terminal using the first transmission means. The first SSID including vacancy information that can specify that the room is vacant is broadcasted in a non-security state.

  Thereby, the first SSID including the vacancy information is displayed on the display means such as the display screen of the portable terminal that has received the first SSID. Here, when a vacant room is reserved based on the vacancy information among a plurality of portable terminals that have received the first SSID, it becomes the first portable terminal on the condition that the reservation is completed. Note that a (fixed) common SSID used for providing services is transmitted to the first portable terminal in a non-security state, and a connection with the first portable terminal is established by the common SSID.

  On the other hand, the user who has completed the reservation and received the service as described above and who owns the first mobile terminal can, for example, after the reservation is completed and before entering the reserved room via the second transmission means. At the time of reservation or during use (in use) after entering the room, the second SSID including call request information for recruiting other users who share the use of the room can be broadcasted in a non-security state.

  As a result, the user and other users can receive the broadcast-transmitted second SSID and display it on the display screen or the like, and use it separately from the first SSID including the vacancy information on the store side in the karaoke store. It is possible to display the call-in request information on the subscriber side. At this time, a mobile terminal owned by a user other than the user who owns the first mobile terminal becomes the second mobile terminal.

  Therefore, the user of the second portable terminal can share (share) and use the same room as the room reserved or used by the user using the second SSID including the call request information. Similarly to the above, the common SSID used for service provision is also transmitted to the second portable terminal in a non-security state, and a connection with the second portable terminal is established by this common SSID. That is, both the first mobile terminal and the second mobile terminal establish a connection using the same common SSID.

  As described above, for example, the number of people designated by the number of people designation information included in the second SSID or the number of people called in the range of the maximum number of people can be shared and the room where the karaoke apparatus is installed can be shared. As a result, convenience on the user side can be improved.

  According to the present invention, convenience on the user side can be improved.

  Furthermore, a conversion circuit 39 for receiving information by infrared communication with the remote control device 60 is connected to the CPU 21 via a light receiving unit 38 provided in the device housing 11 of the main body device 10.

  In the example of the present embodiment, the remote control device 60 is configured as a dedicated device in the karaoke service system 1, but a mobile terminal 51 (52) such as a smartphone or a tablet terminal having an equivalent functional configuration is used. Also good. In this case, it is necessary to install in advance an application program that realizes a function equivalent to that of the remote control device 60 in the portable terminal 51 (52). The application program may be downloaded through the Internet line, or may be downloaded from the POS terminal 70 or the main device 10 after visiting the store. In particular, when an application program stored in the ROM 23 or the HDD 27 of the main unit 10 is installed, it is possible to easily download the application program with an identification code so that communication with the main unit 10 in another room is not established. it can.

  Thus, the karaoke store is provided with the POS terminal 70 in the reception counter etc. in a karaoke store, for example. Also, the main device 10 of the karaoke apparatus installed in each room R1, R2 of the karaoke store performs wired LAN communication with the wireless LAN control unit 33 that performs wireless LAN communication with the mobile terminal 51 (52) such as a smartphone and the POS terminal 70. Two systems of communication means with the wired LAN control unit 26 are provided.

  Further, the main unit 10 of the karaoke apparatus is composed of a performance means such as a monitor 16 and a speaker 20 for outputting karaoke music, a remote control device 60 as a log-in means for reserving music after user login, and the main apparatus 10 of the karaoke apparatus are not performing And a POS terminal 70 (or CPU 21) as an idle state detecting means for detecting an idle state where the user is not logged in.

  When the main unit 10 of the karaoke apparatus installed in each of the rooms R1 and R2 detects an idle state under the control of the CPU 21, the room in which the main unit 10 of the karaoke apparatus is installed from the wireless LAN control unit 33 via the antenna 32. Vacancy information that allows the user to specify that R1 and R2 are in a vacant state (for example, room R2 in FIG. 1), such as a temporary number, a store name, a room number, a vacant state, a reservation state, etc. The first dynamic SSID including is broadcasted in a non-security state. In addition, since SSID (Service Set Identifier) has character information limited (32 characters), necessary vacancy information is transmitted as the first dynamic SSID within this range.

  On the other hand, the mobile terminal 51 (52) receives the first dynamic SSID broadcasted and displays it on the display screen 50a, and also indicates that the mobile terminal 51 (52) that received the broadcast transmission is the POS terminal 70 ( Alternatively, the main device 10) of the karaoke device is detected.

  Here, when a reservation is made from the same portable terminal 51 (52), the main device 10 of the karaoke apparatus can identify the first dynamic SSID as a non-vacancy information that can be identified as a non-vacancy state. For example, the broadcast name is changed to a new first dynamic SSID including a store name, a room number, being used, or reserved, and broadcasted.

  Thereby, for example, the portable terminal 51 owned by the user who made the reservation is identified as the first portable terminal 51, receives the first dynamic SSID broadcasted, and displays the reservation status on the display means. You can confirm your reservation.

  Therefore, the main device 10 of the karaoke apparatus broadcasts the first dynamic SSID in units of the rooms R1 and R2, so that the user side does not have access to the POS terminal 70 and is now vacant. A simple SSID can recognize a vacant state, a reservation state in which an available time can be confirmed even if it is currently in use.

  When the reservation is made, the main device 10 of the karaoke device broadcasts a new first dynamic SSID that recognizes that the device is in a non-vacant state. Can confirm the reservation operation, and can make other portable terminals 52 to use from now know that they are in a non-vacant state.

  The POS terminal 70 can be used for customer service after reservation by notifying the main device 10 of the karaoke apparatus via the wired LAN line 12 that the reservation has been made.

  The first portable terminal 51 confirms the store visit with the POS terminal 70 when visiting the store, and acquires identification information for wireless connection with the POS terminal 70 or the main device 10 installed in the reserved room R2. Thus, it is possible to contribute to facilitation (simplification) of the wireless connection with the main body device 10 while the room R2 is being used.

  Next, the user who owns the first portable terminal 51 enters the second motion including the call request information for recruiting other users who share the use of the room using the static SSID after entering the room R2. The second dynamic SSID is broadcasted to the second portable terminal 52 through a process for a procedure for broadcasting the target SSID in a non-security state.

<Features of this embodiment>
Next, a service example of this embodiment will be described based on FIG. In the sequence shown in FIG. 3, the order of the procedure S is indicated by a number in [].

  First, in step S1, since the POS terminal 70 grasps the use state and reservation state of each room in the entire karaoke store, in order to make the main body device 10 recognize that in the idle state that is an empty room. Output the notification. In this notification, a temporary number used when making a reservation is issued, and the temporary number is notified.

  Next, in step S2, the main unit 10 provides the wireless LAN control unit 33, which is an access point (wireless communication means / first transmission means), in addition to a temporary number, for example, store name, room number, vacant state, etc. The first dynamic SSID creation instruction including vacancy information necessary for the reservation such as the reservation state is notified.

  In step S3, the wireless LAN control unit 33 broadcasts the first dynamic SSID from the antenna 32 in a non-security state (see also FIG. 4A).

  On the other hand, in step S4, the first portable terminal 51 displays the received first dynamic SSID on the display screen 51a by receiving the first dynamic SSID. Thereby, the first dynamic SSID including the vacancy information such as “JOY XXX Rm201 OK” is displayed on the display means 51a. Of the vacancy information “JOY XXX Rm201 OK”, “JOY” represents the store name, “Rm201” represents the room number of the room R2, “OK” represents the vacant room, and “XXX” represents the temporary number. On the contrary, when “OK” is “NG”, this indicates that the room is in use (or reserved) information. Note that the vacancy information and in-use information are part of the first dynamic SSID.

  Here, in step S <b> 5, the first mobile terminal 51 notifies the POS terminal 70 of the received temporary number, thereby accepting the user's mobile terminal that has received the first dynamic SSID as the first mobile terminal 51.

  Thereafter, in step S6, the first portable terminal 51 temporarily connects to the wireless LAN control unit 33 using the reservation number, the temporary number, and the like after the reception at the POS terminal 70 is completed. That is, in this procedure S6, the wireless LAN control unit 33 configures a first connection detection unit that detects a connection from the first portable terminal 51 that has received the broadcast transmission of the first dynamic SSID.

  In step S7, the main device 10 and the first mobile terminal 51 display, for example, a reservation Web page on the display screen 51a of the first mobile terminal 51 to perform reservation processing for the room R2, and at the time of visiting the store, the POS terminal A reservation notice and a reservation number for accepting a store visit between the terminal 70 and the first portable terminal 51 are issued and stored.

  In step S8, the first portable terminal 51 uses, for example, a reservation number (or a member number after reception) for the main body device 10 installed in the room R2 after reception with the POS terminal 70 when visiting the store. To notify the wireless connection information and establish a wireless LAN connection.

  In step S <b> 9, the main device 10 notifies the wireless LAN control unit 33 of a static SSID creation instruction. The static SSID is used to identify the first mobile terminal 51 between the main device 10 and the first mobile terminal 51 and to eliminate connection with other mobile terminals, that is, the room R2 and its use. Wireless LAN connection in association with a person.

  However, in step S10, the wireless LAN control unit 33 broadcasts the static SSID from the antenna 32 in a non-security state, not only to the first portable terminal 51. As will be described later, this static SSID is also transmitted to the subsequent second mobile terminal 52 (that is, shared by the first mobile terminal 51 and the second mobile terminal 52).

  In step S11, the first mobile terminal 51 establishes the main connection with the wireless LAN control unit 33 using the wireless connection information in step S8 and the received static SSID (see FIG. 4B). . Here, the static SSID includes a character string that allows the first mobile terminal 51 to call the room device R2 in a shared (shared) manner with the main body device 10.

  In step S <b> 12, the first mobile terminal 51 notifies the main body device 10 of the number of people who call to use the room R <b> 2 jointly (shared).

  In step S13, the main device 10 calls the call request information corresponding to the number of callers who recruit other users who share the use of the room R2, with respect to the wireless LAN control unit 33 which is an access point (second transmission means). An instruction to create a second dynamic SSID including is notified.

  In step S14, the wireless LAN control unit 33 broadcasts in a non-security state a second dynamic SSID including call request information corresponding to the number of callers seeking other users who share the use of the room R2 ( (Refer FIG.4 (b)).

  In step S15, when the second mobile terminal 52, which is a mobile terminal different from the first mobile terminal 51, receives the second dynamic SSID, the received second dynamic SSID is displayed on the display screen 52a. The second dynamic SSID may be exactly the same as the first dynamic SSID, or for example, a unique second dynamic SSID including call request information such as “JOY XXX Rm2012” is displayed. Of the “JOY XXX Rm2012”, which is the call request information, “JOY” is the store name, “Rm201” is the room number of the room R2, “2” is the number of people to call, and “XXX” is the temporary number. . If “2” is “NG”, this indicates that the room is call completion information.

  In step S <b> 16, the second portable terminal 52 temporarily connects to the wireless LAN control unit 33. That is, in this procedure S16, the wireless LAN control unit 33 configures a second connection detecting unit that detects a connection from the second portable terminal 52 that has received the broadcast transmission of the second dynamic SSID.

  In step S17, the main device 10 and the second mobile terminal 52 display, for example, a reservation Web page on the display screen 52a of the second mobile terminal 52, perform a request process for calling the room R2, and at the time of visiting the store, A reservation notice (or the number of people who want to be called) and a reservation number for accepting a store visit between the terminal 70 and the second portable terminal 52 are issued and stored.

  In step S18, the second portable terminal 52 uses, for example, a reservation number (or a member number after reception) for the main body device 10 installed in the room R2 after reception with the POS terminal 70 at the time of visiting the store. To notify the wireless connection information and establish a wireless LAN connection.

  In step S19, the main device 10 notifies the wireless LAN control unit 33 of a static SSID creation instruction again. This static SSID is the same SSID as that transmitted in the procedure 10 (that is, the SSID shared with the first mobile terminal), and the main device 10 and the first mobile terminal 51 and further the second mobile terminal 52 are connected. It is for associating and making a wireless LAN connection.

  In step S20, the wireless LAN control unit 33 broadcasts the shared static SSID from the antenna 32 again in a non-security state.

  In step S21, the second mobile terminal 52 establishes the main connection with the wireless LAN control unit 33 using the wireless connection information in step S18 and the received shared static SSID (FIG. 4C). reference).

  Thereafter, the same method as described above is repeated, and new mobile terminals (third mobile terminal, fourth mobile terminal,...) Using new dynamic SSIDs (third dynamic SSID, fourth dynamic SSID,...).・) Invite users sequentially. Then, for the user's mobile terminal after the call, a connection is sequentially established using the shared static SSID common to the first and second mobile terminals 51 and 52 (FIG. 4 (d). )reference).

  It should be noted that in the above-mentioned notification of the number of people calling in step S12, when the number of people called is limited (for example, “limited to two people”), or when the maximum number of people is called (for example, “two people at maximum” )).

  At this time, in both cases of “limited to two people” and “maximum (total) of two people”, a plurality of groups (or individuals) including the third mobile terminal can be used.

  As a result, the user who owns the first mobile terminal 51 obtains the vacancy information and makes a reservation, and in the desired period from the completion of the reservation to leaving the room, the user who owns the second mobile terminal 52 Invite users. As a result, convenience on the user side can be improved.

  In addition to those already described above, the methods according to the above embodiments may be used in appropriate combination.

  For the reservation number, for example, information for identifying a portable terminal such as an IP address or a MAC address may be used.

  That is, as a result of using smartphones for the first mobile terminal 51 and the second mobile terminal 52, the user who enters the room R2 of the main body device 10 has the smartphone, so the first dynamic SSID and the second As long as the user notified to the dynamic SSID and the number of people notified by the user, a user who does not have a smartphone can enter the room R2.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
