[0003] [Patent Document 1] JP 2020-53884 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above conventional system where a mobile terminal can be used instead of the room master unit, when a call is received and the user tries to answer using the mobile terminal, the user may mistakenly end the call. If this happens, the call path is cut off, and the mobile terminal cannot re-establish the call path, making it impossible to answer the call.

[0005] In view of the above problems, the present invention aims to provide an intercom system for an apartment building that can form a call path and respond to a call even if a mobile terminal that receives a call from the apartment entrance unit and attempts to respond is mistakenly operated to end the call. [Means for solving the problem]

[0006] In order to solve the above problem, the invention of claim 1 is an apartment house intercom system comprising a collective entrance unit installed at an entrance so that visitors can call residents and talk to them, a room master unit installed in each dwelling unit of the apartment house to answer calls from the collective entrance unit, and a mobile terminal carried by the resident, and in which calls from the collective entrance unit can be answered by the mobile terminal via an external general-purpose network, and a communication management server is disposed on the general-purpose network, which manages the transmission of call signals from the collective entrance unit to the mobile terminal and the communication between the two, and the collective entrance unit transmits a call signal to the room master unit of the dwelling unit selected in response to a call operation and to the communication management server, and the communication management server has a communication control unit which, upon receiving a call signal from the collective entrance unit, identifies the mobile terminal of the called dwelling unit from the call signal and performs call control on the identified mobile terminal to control the formation of a call path between the collective entrance unit and the mobile terminal, and the communication control unit further recognizes that a communication disconnection operation has been performed on the mobile terminal that has received the call and then performs a reconnection operation, and controls reconnection between the mobile terminal and the collective entrance unit. The collective entrance unit and the room master unit communicate between the devices by IP communication, and the mobile terminal has an application installed thereon for responding to a call from the collective entrance unit, enabling communication with the collective entrance unit via a communication management server. The communication management server has an application information storage unit that stores the application installed on each mobile terminal in association with information on the dwelling unit to which the mobile terminal belongs. The communication control unit that receives a call signal from the collective entrance unit selects an application associated with the dwelling unit from information in the application information storage unit based on the dwelling unit information included in the received call signal, and performs call control. When the called mobile terminal responds, a call path is formed with the collective entrance unit via the communication management server. It is characterized by: With this configuration, even if communication between the mobile device and the collective entrance unit is cut off by an operation on the mobile device, if a reconnection operation is performed on the mobile device, the connection can be re-established under the control of the communication management server. Therefore, even if the call is ended by mistake, the call with the visitor can be resumed, which is convenient.

[0007] In addition, A mobile device can communicate with the collective entrance device by installing an application for communicating with the collective entrance device and registering it in the communication management server, so residents do not need to register the address of the collective entrance device, etc. Also, the collective entrance device only needs to be able to communicate with the communication management server, so there is no need to register the mobile device to be called. Therefore, communication between the collective entrance device and the mobile device can be achieved with simple operations.

[0008] Claim 2 The invention is as follows: 1In the configuration described above, the communication management server has a timer unit for limiting the time during which a mobile terminal can reconnect to the collective entrance unit to a certain period of time, and the communication control unit is characterized in that it disables the mobile terminal from performing the reconnection operation after the certain period of time has elapsed. According to this configuration, reconnection is not possible after a certain period of time has passed, so reconnection operations can be prohibited when a visitor you wish to talk to has left and a different person is in front of the collective entrance unit, preventing privacy issues from occurring. Effect of the Invention

[0009] According to the present invention, even if communication between a mobile terminal and a collective entrance unit is cut off by an operation on the mobile terminal side, if a reconnection operation is performed on the mobile terminal side, the communication can be reconnected under the control of the communication management server. Therefore, even if a call is ended by mistake, the call with the visitor can be resumed, which is convenient. [Brief description of the drawings]

[0010] [Figure 1] 1 is a configuration diagram showing an example of an apartment building intercom system according to the present invention; [Diagram 2] FIG. 2 is a functional block diagram of the communication management server. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is a block diagram showing an example of an apartment house intercom system according to the present invention. The apartment house intercom system includes an apartment entrance unit 1 installed at the entrance of the apartment house for visitors to call residents, a room master unit 2 installed in each dwelling unit for responding to calls from the apartment entrance unit 1, a master unit 3 installed at the entrance of each dwelling unit for calling residents, a management master unit 4 installed in the manager's room for calling residents, a mobile terminal 5 carried by the resident, and a communication management server 6 installed outside.

[0012] At least one room master unit 2 and one management master unit 4 are installed in each dwelling unit or manager's room, but here, two of each are shown. Reference numeral 8 denotes a HUB, and each device is connected to a LAN via a communication line L1. Communication between the devices is carried out by IP (Internet Protocol). Furthermore, a communication management server 6 is placed on an external general-purpose network N, and the collective entrance device 1 is connected to the general-purpose network N via a GW (Gateway) adapter 7, enabling communication with the communication management server 6.

[0013] The collective entrance device 1 is equipped with a camera 11 for capturing images of visitors, an operation unit 12 for selecting or inputting the residence to be called, a display unit 13 for displaying the call destination, etc., a microphone 14 and speaker 15 for making calls, a call button 16, etc.

[0014] The room master unit 2 is equipped with a call button 21 for answering a call, a microphone and speaker for making a call, a monitor 23 for displaying an image captured by a camera, an operation unit 24 for performing various operations, and the like.

[0015] The mobile terminal 5 can be, for example, a smartphone, and application software (hereinafter referred to as an "intercom app") for communicating with the collective entrance unit 1 is downloaded and installed from the communication management server 6 via the general-purpose network N. At that time, dwelling unit information such as the dwelling unit number of the resident who is the operator is sent from the mobile terminal 5 to the communication management server 6, and is registered in association with the intercom app. The intercom app installed on the mobile terminal 5 is an app for communicating between the collective entrance unit 1 and the mobile terminal 5, and is application software that enables communication using VoIP technology. By using VoIP technology, the mobile terminal 5 communicates with the collective entrance unit 1 without relying on a telephone number.

[0016] Fig. 2 shows a functional block diagram of the communication management server 6. As shown in Fig. 2, the communication management server 6 includes an application information storage unit 61, a timer unit 62 that manages the time when reconnection is possible, a server CPU 63 that controls communication between the collective entrance unit 1 and the mobile terminal 5 and also controls the communication management server 6, a server communication IF 64 that communicates with the collective entrance unit 1 and the mobile terminal 5 via the general-purpose network N, and the like. In the application information storage unit 61, an intercom application for each mobile terminal 5 is registered in association with a dwelling unit number (a dwelling unit master ID). When a call signal is received, a call is made to the intercom application associated with the called dwelling unit, and the mobile terminal 5 performs a call operation according to this call control. That is, a call signal is transmitted to the mobile terminal 5.

[0017] On the other hand, the called mobile terminal 5 can recognize from the ring tone and call display that the call is from the collective entrance device 1. The called mobile terminal 5 is registered in a call history storage unit (not shown), and connection operations can be performed from the mobile terminal 5 based on the registered history information.

[0018] The operation of the apartment complex intercom system configured as described above is as follows: The operation of operating the apartment complex entrance unit 1 to call a resident, causing the room master unit 2 of the called residence to sound a ring tone, the operation of establishing a call path when the room master unit 2 responds to the call, the operation of transmitting the image captured by the camera 11 in response to the call and displaying it on the monitor 23 of the room master unit 2, and other operations are the same as those of the conventional system, so a description thereof will be omitted. Here, an operation of answering a call from the collective entrance device 1 at the mobile terminal 5, and an operation of reconnecting (retrying the call) after ending the call at the mobile terminal 5 will be described.

[0019] When the collective entrance unit 1 is operated, an apartment is selected and a call is made, the call signal and the image captured by the camera 11 are transmitted to the room master unit 2 of the selected apartment, and at the same time, are also transmitted to the communication management server 6 via the GW adapter 7 and the general-purpose network N. The communication management server 6 that has received the call signal reads the intercom app associated with the dwelling unit information from the app information storage unit 61 based on the called dwelling unit information included in the call signal, and makes a call using the read intercom app. This call calls the mobile terminal 5 associated with the called room master unit 2 via the general-purpose network N. Also, the captured image of the camera 11 is transmitted.

[0020] Upon receiving the call, the mobile terminal 5 performs a calling operation, and a message is displayed on the display unit 51 indicating that the call is from the collective entrance device 1. Furthermore, the image captured by the camera 11 is displayed on the display unit 51. When the mobile terminal 5 is operated to answer, a response signal is sent to the communication management server 6, and the communication management server 6, which receives the response signal, establishes a call path between the collective entrance unit 1 and the mobile terminal 5 via itself. The collective entrance unit 1 stops sending the call signal to the room master unit 2 upon receiving the call path establishment.

[0021] The above is an explanation of the operation when using the mobile terminal 5 instead of the room master unit 2 to answer a call from the collective entrance unit 1, but when trying to answer a call from the collective entrance unit 1 with the mobile terminal 5, there are cases where the call is ended by mistake, or the call is ended by mistake while answering. In such cases, the call can be re-attempted by the following operation. The user operates the mobile terminal 5 to open the incoming call history, selects the collective entrance unit 1 as the call destination, and performs a connection operation. This operation causes the mobile terminal 5 to transmit a reconnection signal to the communication management server 6 in order to reconnect with the collective entrance unit 1.

[0022] Meanwhile, in the communication management server 6, upon receiving the call end operation from the mobile terminal 5, the server CPU 63 controls the communication path between the collective entrance unit 1 and the mobile terminal 5 to disconnect the call path, but at the same time starts the timer unit 62 to begin counting a fixed period of time, such as 60 seconds. Thereafter, when a reconnection signal is received from mobile terminal 5, it recognizes that the signal is from mobile terminal 5 that made the call using the intercom app, and if the count of timer unit 62 has not elapsed a set period of time, it performs reconnection control and transmits a connection signal to collective entrance unit 1. When collective entrance unit 1 receives the connection signal, if it is in standby mode, it starts up camera 11 and begins transmitting captured video. Incidentally, the control by which the collective entrance unit 1 receives this connection signal and outputs the image captured by the camera 11 is a control that has conventionally been possible by operating the room master unit 2.

[0023] The output captured image is transmitted to and displayed on the mobile terminal 5 via the communication management server 6. If the resident who is the operator of the mobile terminal 5 checks the image and confirms the presence of a visitor, the resident can then perform a predetermined call operation to re-establish a call path with the collective entrance unit 1, making it possible to resume the call.

[0024] However, if the collective entrance unit 1 that received the connection signal is being operated by another visitor and is in use, the image is sent to the mobile terminal 5. Then, a signal that connection is not possible is returned, and a message to that effect is displayed on the mobile terminal 5. This message allows the resident operating the mobile terminal 5 to recognize from the displayed image and the message indicating that connection is not possible that a call cannot be made, and causes the resident to end the call.

[0025] In this way, even if the communication between the mobile terminal 5 and the collective entrance device 1 is cut off by an operation on the mobile terminal 5 side, if a reconnection operation is performed on the mobile terminal 5 side, the communication can be reconnected under the control of the communication management server 6. Therefore, even if the call is ended by mistake, the call with the visitor can be resumed, which is convenient. Furthermore, since the mobile terminal 5 can communicate with the collective entrance unit 1 by installing an application for communicating with the collective entrance unit 1 and registering it in the communication management server 6, the resident does not need to register the address of the collective entrance unit 1, etc. Furthermore, the collective entrance unit 1 only needs to be able to communicate with the communication management server 6, and does not need to register the called mobile terminal 5. Therefore, communication between the collective entrance unit 1 and the mobile terminal 5 can be achieved with a simple operation. Furthermore, since reconnection is not possible after a certain time has passed, reconnection operations can be prohibited when a visitor you wish to talk to has left and a different person is in front of the collective entrance unit 1, thereby preventing privacy issues from occurring.
