It is a figure which shows the structure of the intercom system which concerns on modification 4.

Before giving a concrete description of the present disclosure, an outline will be given. An embodiment relates to an intercom system installed in a condominium, an apartment, or other collective facility. A plurality of facilities such as residences are gathered in the collective facility, and people can enter and exit at at least one common entrance. When a visitor operates an entrance device such as a lobby intercom installed at the common entrance, the housing information board installed at the facility of the visitor is called up. In response to the call, the resident of the facility confirms the visitor by operating the housing information board. When the resident operates the housing information board to answer the call, a visitor call between the entrance device and the housing information board is executed.

In addition, in the facility, the auxiliary device may be installed in a room different from the room in which the housing information panel is installed. By communicating with the housing information board, the sub-device executes a visitor call with the entrance device via the housing information board. Further, in the facility, a mobile terminal device such as a smart phone, a tablet, or a PC may be connected to a housing information panel. The connection between the mobile terminal device and the housing information panel may be made via a router. The mobile terminal device executes a visitor call with the entrance device via the housing information board.

In order to execute a visitor call on any of the housing information board, the sub device, and the mobile terminal device, the call request from the entrance device is transmitted to the housing information board and from the housing information board to the sub device and the mobile terminal device. Is also sent. In addition to the call request, the audio signal and the video signal acquired at the entrance device are also transmitted to the housing information board, the sub device, and the mobile terminal device. Further, when there are a plurality of sub-devices or mobile terminal devices, the call request, audio signal, and video signal are transmitted to all of the plurality of sub-devices or mobile terminal devices. When the resident responds to such a call request with any of the housing information panel, the sub-device, and the mobile terminal device, for example, one sub-device, a visitor call is made between the one sub-device and the entrance device. Is done.

Generally, the entrance device and the housing information board are connected via a control device for controlling a visitor call, and a cable such as a trunk line is used for these connections. As the scale of the collective facility increases, the number of dwelling units increases, and as a result, the number of devices such as housing information boards used in the intercom system increases. As a result, the man-hours for cable connection work increase. In order to suppress such an increase in man-hours, it is effective to connect the entrance device, the housing information panel, etc. by a wireless communication system.

When a wireless LAN (Local Area Network) is used as the wireless communication system, since the wireless LAN is self-employed, an increase in the operating cost of the interphone system can be suppressed. However, the wireless LAN is often used in each dwelling unit, and the communication speed may decrease due to interference or the like. When the communication speed decreases, the quality of the visitor call deteriorates. Further, considering the size of the communicable area of the wireless LAN access point, relaying by a large number of access points is required, which may complicate the processing. On the other hand, when a public mobile communication system (4G, 5G, etc.) is used as the wireless communication system, deterioration of the quality of the visitor call is suppressed. Further, since the entrance device, the housing information board, etc. may be directly connected to the base station device of the public mobile communication system, the complexity of the processing by the relay is suppressed. However, since a communication fee is required to use a public mobile communication system, the operating cost of the intercom system increases.

In the intercom system according to this embodiment, a self-employed mobile communication system is used as the wireless communication system. A self-employed mobile communication system is a technology that uses a mobile communication system only in a specific place, and is also called "private LTE (Long Term Evolution)" or "local 5G". In a self-employed mobile communication system, 4G, 5G, etc. are used in the same manner as in a public mobile communication system, so that deterioration of the quality of visitor calls is suppressed, and complication of processing by relay is suppressed. In addition, unlike public mobile communication systems, self-employed mobile communication systems are not operated and managed by telecommunications carriers, so an increase in operating costs for intercom systems is suppressed.
