  By the way, in addition to a mobile phone line, a wireless LAN (for example, IEEE 802.11) can be used as a communication means in a recent user portable terminal (for example, a smartphone). In addition, a karaoke store where a network of karaoke systems (hereinafter referred to as a network) in which a large number of karaoke apparatuses are installed is often used with a wireless LAN. Therefore, it is conceivable that the user portable terminal logs in to the karaoke system using the wireless LAN of the karaoke store.

  At this time, karaoke apparatuses composed of a plurality of different models may be mixed in the LAN in the karaoke store. In such an environment, an operation may be performed in which communication between karaoke apparatuses of different models is restricted by constructing subnets with a plurality of address spaces for each model of karaoke apparatus in one LAN.

  For example, in a network (IP network) environment using the Internet protocol, a different subnet is assigned to each model of karaoke apparatus by setting a network address. Therefore, when a plurality of subnets different for each model of the karaoke apparatus are constructed in the network that is a communication connection destination from the user portable terminal via the wireless LAN, a unique IP address corresponding to each of the plurality of subnets is assigned to the user. It is necessary to prepare for mobile terminals. However, the conventional address lease server can only assign IP addresses to user portable terminals in a uniform address range.

  The present invention has been made to solve the above problems. An object of the present invention is to dynamically assign an address according to the subnet to which the karaoke device belongs to a user portable terminal that selectively remote-operates a karaoke device that belongs to a plurality of different subnets in the network.

The first transmission means identifies the terminal to the karaoke device corresponding to the acquired specific information based on the terminal identification information and specific information acquired by the first acquisition means and the specific information stored in the first storage means. Send information from the management server.

  A 2nd acquisition means acquires the terminal identification information which the karaoke apparatus received from the management server, and the address of the karaoke apparatus which received the terminal identification information. The association information recording means records the terminal identification information of the user portable terminal acquired by the second acquisition means and the address of the karaoke device in association with each other and records them in the second storage means. The allocating means determines the address of the user portable terminal that can communicate with the address of the karaoke apparatus based on the terminal identification information of the user portable terminal stored in association with the second storage means and the address of the karaoke apparatus, The determined address is assigned to the user portable terminal corresponding to the terminal identification information.

  In this way, in a network in which a plurality of subnets are constructed, the karaoke device associated as a specific communication partner and the user portable terminal can communicate with each other according to the address on the karaoke device side. Thus, the address on the user portable terminal side can be dynamically assigned. Therefore, it is not necessary to prepare a plurality of unique addresses corresponding to a plurality of subnets in advance for the user portable terminal, and the addresses can be used efficiently.

  In addition, as an address given to the user portable terminal associated with the karaoke device, an address belonging to the same subnet as the address of the karaoke device is assigned to the user portable terminal corresponding to the terminal identification information as described in claim 2. It is conceivable that the address is assigned. For example, in an IP network environment, a subnet is defined by a network address portion of an IP address. Therefore, by assigning an IP address having a network address common to the IP address of the associated karaoke apparatus to the user portable terminal, the karaoke apparatus and the user portable terminal can be made communicable.
