Whether or not the music selection reservation is permitted is determined based on two conditions.

  The first music selection reservation permission condition is that the time when the music selection reservation information is received from the personal mobile terminal having the mobile terminal identification information included in the pairing permission information is the pairing permission information associated with the mobile terminal identification information. It is within a first predetermined time (for example, 2 hours) from the included pairing instruction time. Further, the second music selection reservation permission condition is that the time when the music selection reservation information is received is within a second predetermined time (for example, a variable time with 10 minutes as a default) from the music selection reservation time included in the pairing permission information. It is to be. Note that the second predetermined time is shorter than the first predetermined time. Further, the second predetermined time is increased or decreased according to the number of mobile terminal information (number of users) that is paired in the pairing permission information related to the karaoke performance terminal paired with the personal mobile terminal.

  When both the first music selection reservation permission condition and the second music selection reservation permission condition are satisfied, the music selection reservation based on the music selection reservation information is permitted. On the other hand, if either or both of the first music selection reservation permission condition and the second music selection reservation permission condition are not satisfied, the music selection reservation based on the music selection reservation information is not permitted.

  Further, the pairing permission information update unit deletes the pairing permission information that has passed a first predetermined time (for example, two hours) from the pairing instruction time from the pairing management database. That is, with the pairing instruction time as the beginning, there is a limit on the longest time during which pairing is permitted.

  Further, when the next music selection reservation information is received within the second predetermined time from the time when the previous music selection reservation information was received, the music selection of the pairing permission information associated with the mobile terminal information included in the music selection reservation information The reservation time is updated to the time when the next music selection reservation information is received. That is, each time a music selection reservation is made, the music selection reservation time in the pairing permission information constituting the pairing management database is updated.

  On the other hand, when the next music selection reservation information is not received within the second predetermined time from the time when the previous music selection reservation information is received, the pairing permission information associated with the mobile terminal information included in the music selection reservation information is paired. Delete from the ring management database. In other words, if the music selection reservation is not made within the second predetermined time, the pairing is terminated even if the first predetermined time has not elapsed.

  In the relay server, by the function of the music selection reservation information transfer means, at least the performance terminal identification paired with the mobile terminal identification information included in the music selection reservation information, the music ID included in the music selection reservation information permitted to be reserved for music selection The information is transferred to a karaoke performance terminal having information. In the karaoke performance terminal that has received the music selection reservation information, a reservation queue is created by the function of the reservation management means, and the music selection reservation information including the received music ID is managed. In addition, when music selection information (user ID) etc. are contained in music selection reservation information, music reservation information (user ID) etc. can be included and managed in a reservation queue.

  In the karaoke music selection system using the personal portable terminal of the present invention, not only can the personal portable terminal be used as a remote controller for music selection reservation, but also when the user makes a music selection reservation, the karaoke performance terminal and the personal portable terminal. When a predetermined time or more has elapsed since the pairing start and no music selection reservation is made at every predetermined time interval, music selection reservation using the personal portable terminal cannot be performed. And the predetermined time interval which must perform music selection reservation is increased / decreased according to the number of users who perform music selection reservation using a personal portable terminal in the same karaoke performance terminal.

  For example, a personal portable terminal can be used as a music selection reservation remote control device at any karaoke performance terminal for a maximum of two hours, and a user who makes a music selection reservation using the personal portable terminal at the karaoke performance terminal. If the number is large, the predetermined time interval at which the music selection reservation must be made becomes long, and conversely, if the number of users who make a music selection reservation using the personal portable terminal at the karaoke performance terminal is small, the music selection reservation must be made. The predetermined time interval that should not be shortened.

  As described above, according to the karaoke music selection system using the personal portable terminal of the present invention, there is a limit to the time during which the personal portable terminal can be used as a music selection reservation remote control device in any karaoke performance terminal. If you exceed the limit, you will have to pair the karaoke performance terminal with your personal mobile device again. Is possible.

  In addition, the personal portable terminal and the pairing information are included only when the pairing information is received before a predetermined time (for example, 5 minutes) elapses from the pairing instruction time included in the pairing information. In the case of a configuration that allows pairing with a karaoke performance terminal having performance terminal identification information, even if the user logs in to the karaoke system to make a music selection reservation using a personal portable terminal, within a predetermined time If the music selection reservation using the personal portable terminal is not performed, the pairing between the karaoke performance terminal and the personal portable terminal is not performed, so that it is possible to reduce the burden of the pairing management process in the relay server.

The pairing permission determination may be performed in the management server.

<Pairing permission information creation means>
When the pairing permission information creating unit 21 receives the pairing information from any personal portable terminal 50, the pairing permission information corresponding to the combination of the performance terminal identification information and the portable terminal identification information included in the pairing information is obtained. If there is pairing permission information corresponding to only the performance terminal identification information, the performance terminal identification information included in the pairing information and the mobile terminal identification are searched. The pairing management database 25 creates pairing permission information in which the information, the pairing instruction time of the pairing permission information, and the music selection reservation time that is the same as the pairing instruction time included in the pairing information are associated with each other. If there is no pairing permission information corresponding to the performance terminal identification information, the pairing permission information The pairing management database 25 includes pairing permission information in which the performance terminal identification information, the portable terminal identification information, the pairing instruction time, and the music selection reservation time that is the same as the pairing instruction time are associated with each other. It consists of a program for creating.

  That is, when pairing information is received from an arbitrary personal portable terminal 50, a pair corresponding to the combination of the performance terminal identification information and the portable terminal identification information included in the pairing information by the function of the pairing permission information creating means 21. Whether or not the ring permission information exists in the pairing management database 25 is searched. Thereby, it is determined whether the karaoke performance terminal 30 having the performance terminal identification information included in the pairing information and the personal portable terminal 50 having the mobile terminal identification information are already paired.

  Here, when there is pairing permission information corresponding only to the performance terminal identification information included in the received pairing information, that is, in the karaoke performance terminal 30 having the performance terminal identification information included in the received pairing information, already. When pairing with another personal portable terminal 50 is performed, pairing of performance terminal identification information, portable terminal identification information, and already existing pairing permission information included in the received pairing information Pairing permission information in which the instruction time is associated with the music selection reservation time that is the same as the pairing instruction time included in the pairing information is created in the pairing management database 25.

  That is, at any karaoke performance terminal 30, the user performs an operation for pairing the personal portable terminal 50, and the pairing operation by the user is the second or subsequent pairing from the start of use of the karaoke performance terminal 30. If there is, pairing permission information is created using the pairing instruction time included in the pairing permission information regarding the performance terminal identification information that already exists. Thereby, when the pairing is performed after the start of use of the karaoke performance terminal 30 that has not been paired, the pairing instruction time when the pairing is first performed is set. Since the pairing permission information is created by using the same karaoke performance terminal 30, the same time management can be performed for users who use the same karaoke performance terminal 30 at the same time.

  On the other hand, when the performance terminal identification information included in the received pairing information does not exist in the pairing management database 25, the performance terminal identification information, the mobile terminal identification information, and the pairing instruction included in the received pairing information Pairing permission information in which the time is associated with the music selection reservation time that is the same as the pairing instruction time is created. That is, when the user performs an operation for pairing the personal portable terminal 50 in any karaoke performance terminal 30 that is not yet paired with any personal portable terminal 50, the karaoke performance terminal Create new pairing permission information for.

Only when information is received, it may function to create pairing permission information. When such a function is provided, the user logs into the karaoke system in order to make a music selection reservation using the personal portable terminal 50, and acquires the performance terminal identification information and the pairing instruction time. If pairing is not performed within a predetermined time, pairing using the acquired performance terminal identification information and the pairing instruction time cannot be performed. By providing such a function, unnecessary pairing between the karaoke performance terminal 30 and the personal portable terminal 50 is not performed. Therefore, pairing can be performed without wasting resources necessary for pairing management in the relay server 20. The burden of management processing can be reduced.

<Music selection reservation permission judging means>
The music selection reservation permission determination means 22 is composed of a program for determining whether or not to permit music selection reservation using the personal portable terminal 50 based on the pairing permission information stored in the pairing management database 25.

  In other words, the music selection reservation permission determination means 22 performs the pairing permission in which the time when the music selection reservation information is received from the personal mobile terminal 50 having the mobile terminal identification information included in the pairing permission information is associated with the mobile terminal identification information. The first music selection reservation permission condition is that the time is within the first predetermined time from the pairing instruction time included in the information. The second music selection reservation permission condition is that the time when the music selection reservation information is received is within a second predetermined time shorter than the first predetermined time from the music selection reservation time included in the pairing permission information. .

  When both the first music selection reservation permission condition and the second music selection reservation permission condition are satisfied, the music selection reservation based on the music selection reservation information is permitted. On the other hand, if either or both of the first music selection reservation permission condition and the second music selection reservation permission condition are not satisfied, the music selection reservation based on the music selection reservation information is not permitted.

  Here, the second predetermined time is increased or decreased according to the number of portable terminal information that is paired in the pairing permission information having the same performance terminal identification information. For example, the second predetermined time is 10 minutes as a default when the number of users who make a music selection reservation using the personal portable terminal 50 in the same karaoke performance terminal 30 is one. The number of users increases, such as 13 minutes when there are two users, 16 minutes when there are three users, 19 minutes when there are four users, and 22 minutes when there are five users. According to, the judgment time is set to be increased by 3 minutes. On the other hand, if the number of users who make a music selection reservation using the personal portable terminal 50 in the same karaoke performance terminal 30 decreases, the second predetermined time is also shortened accordingly.

  As described above, the second predetermined time is set according to the number of users because the waiting time for reservation for music selection increases as the number of users who make a reservation for music selection using the personal portable terminal 50 in the same karaoke performance terminal 30 increases. This is because, on the contrary, if the number of users is small, it is considered that the waiting time for music selection reservation is shortened.

<Pairing management database>
As shown in FIG. 4, the pairing management database 25 is configured by associating performance terminal identification information, portable terminal identification information, pairing instruction time, and music selection reservation time that is the time at which music selection reservation information is received. In this embodiment, the database includes the number of mobile terminal identification information (number of users) paired in pairing permission information having the same performance terminal identification information. The data constituting the pairing management database 25 is not limited to that shown in FIG. 4 and may include other data.

<Pairing permission information update means>
The pairing permission information update unit 23 deletes the pairing permission information that has passed the first predetermined time from the pairing instruction time from the pairing management database 25, and the second predetermined time from the time when the previous music selection reservation information was received. When the next music selection reservation information is received within the time, the music selection reservation time in the pairing permission information associated with the mobile terminal information included in the music selection reservation information is updated to the time when the next music selection reservation information is received. When the next music selection reservation information is not received within the second predetermined time from the time when the previous music selection reservation information is received, the pairing permission information associated with the mobile terminal information included in the music selection reservation information is paired. It consists of a program for deleting from the management database 25.

  In other words, the pairing permission information update unit 23 deletes the pairing permission information from the pairing management database 25 after the first predetermined time (for example, 2 hours) has elapsed from the pairing instruction time, whereby the pairing instruction time As a starting point, there is a limit on the maximum time allowed for pairing.

  Further, when the next music selection reservation information is received within the second predetermined time from the time when the previous music selection reservation information was received, the music selection of the pairing permission information associated with the mobile terminal information included in the music selection reservation information By updating the reservation time to the time when the next music selection reservation information is received, the music selection reservation time of the pairing permission information constituting the pairing management database 25 is updated.

  On the other hand, when the next music selection reservation information is not received within the second predetermined time from the time when the previous music selection reservation information is received, the pairing permission information associated with the mobile terminal information included in the music selection reservation information is paired.
