Abstract

PROBLEM TO BE SOLVED: To provide a karaoke system which, even when connection is interrupted between a karaoke remote controller and a radio access point, is capable of speedily establishing connection with another radio access point.SOLUTION: The karaoke system comprises: ESSID setting means 40a which sets the same ESSID for plural radio access points 40 connected to the same segment in a network; and roaming means 22c which, when the connection with an arbitrary radio access point 40 for which the ESSID is set and with which a karaoke remote controller 22 performs radio communication is interrupted, performs roaming on one of the other radio access points 40 given the same ESSID.

Description

  The present invention relates to a karaoke system having a roaming function, and more specifically, includes a plurality of access points that can communicate with a karaoke remote control device, and when communication between the karaoke remote control device and the access point is interrupted, The present invention relates to a karaoke system that can quickly roam to another access point.

  Currently popular karaoke systems perform various operations on karaoke performance terminals such as music selection reservation using a karaoke remote control device having a wireless communication function. In a general karaoke box store, a karaoke performance terminal is installed in each of a plurality of rooms, and each karaoke performance terminal is LAN-connected via a router. In addition, a plurality of access points are connected to the same segment of the network to which the karaoke performance terminal is LAN-connected, and data transmission / reception is performed between the karaoke remote control device and the access point, thereby the karaoke remote control device. In the karaoke performance terminal associated with, operations such as music selection reservation can be performed.

  In a network having a plurality of access points as described above, in order to avoid radio communication interference, an ESSID (Extended Service Set Identifier) is set for each access point, and the access point that permits communication to the karaoke remote control device. By setting the same ESSID, the karaoke remote controller can connect to an access point that is permitted to communicate.

  Conventionally, various techniques for establishing an appropriate connection state between an access point and a terminal device have been proposed (see, for example, Patent Document 1). In the technique described in Patent Document 1, the server establishes a connection between the server and the access point, and determines whether there is an appropriate connection between the server and the access point. And reconfiguring the access point connection options when it is determined that there is an inappropriate connection between the server and the access point. It is a technology that can establish a simple connection state.

  By the way, when the connection between the karaoke remote control device and the access point is lost, the connection with the access point must be attempted again by the communication application installed in the karaoke remote control device. The reconnection process by this communication application requires a plurality of connection establishment steps, and there is a problem that it takes time to reconnect.

  That is, if the connection between the karaoke remote control device and the access point is interrupted, an operation such as music selection reservation using the karaoke remote control device cannot be performed, which causes trouble for karaoke users. Therefore, it has been desired to develop a technique capable of quickly recovering the connection with the access point when the connection between the karaoke remote control device and the access point is interrupted.

  The present invention has been proposed in view of the above-described circumstances, and even if the connection between the karaoke remote control device and the access point is interrupted, the connection between the other access points can be quickly established. An object of the present invention is to provide a karaoke system having a roaming function.

  The karaoke system provided with the roaming function of the present invention has been proposed to achieve the above-described object, and has the following features. That is, a karaoke system having a roaming function according to the present invention includes a plurality of wireless access points connected to the same segment in a network and at least one karaoke performance terminal, and a karaoke remote controller having a wireless communication function. The apparatus is a karaoke system capable of performing operations such as music selection reservation at a karaoke performance terminal associated with the karaoke remote control device by performing wireless communication with any one of the wireless access points, An ESSID setting unit and a roaming unit are provided.

  The ESSID setting means is a means for setting the same ESSID for a plurality of wireless access points. The roaming means is one of the other wireless access points to which the same ESSID is assigned when the connection with the arbitrary wireless access point with which the arbitrary karaoke remote control device set with the ESSID is performing wireless communication is interrupted. One is a means for performing roaming.

  In the configuration described above, the ESSID setting unit can automatically generate an ESSID based on an IP address assigned by the DHCP function in the network.

  According to the karaoke system provided with the roaming function of the present invention, since the same ESSID is set for a plurality of wireless access points connected to the same network, any karaoke remote control device set with the ESSID is wireless. Even if the connection with an arbitrary wireless access point performing communication is interrupted, it is possible to immediately reconnect to any one of the other wireless access points to which the same ESSID is assigned.

  Therefore, even if the connection between the karaoke remote control device and the access point is lost, the connection with the access point is quickly restored, so that operations such as music selection reservation using the karaoke remote control device can be performed. The period during which it cannot be performed can be minimized, and the karaoke user is not frustrated or uncomfortable.

  In addition, when the configuration is such that the ESSID is automatically generated based on the IP address given by the DHCP function, it is possible to save time and labor for generating and setting the ESSID by hand, making it easy to generate and set the ESSID. It can be carried out.
