Description

The present invention relates to an intercom system, and more particularly to an intercom system capable of answering a call from a front door slave unit with a mobile phone.

There is an intercom system that can answer calls from the entrance slave unit with a mobile phone. In such an intercom system, the mobile phone is configured to communicate with the room master unit using the Internet. In this case, the IP address of the mobile phone is assigned a global IP address that is frequently changed, and the call / answer is performed by SIP communication.
Therefore, the room master unit needs to be aware of the latest IP address of the mobile phone. This can be solved by periodically notifying the master unit of the room from the mobile phone of its own IP address, but since there is a problem that the power consumption of the mobile phone becomes large, for example, as disclosed in Patent Document 1. Applying the technology solved this problem.
In Patent Document 1, when a call is generated, an e-mail for obtaining a global IP address is first sent from a living room master unit to a mobile phone, and the latest IP address is obtained from the reply to enable SIP communication.

Japanese Unexamined Patent Publication No. 2013-176005

The technique of Patent Document 1 can suppress the power consumption of the mobile phone because it is not necessary to frequently activate the communication function of the mobile phone with the living room master unit. However, since the mail is first sent and received in response to the call from the entrance slave unit, the time until the mobile phone calls and operates is not smooth, and a certain time delay occurs.

Therefore, in view of such a problem, the present invention provides an intercom system capable of performing a smooth answer while suppressing power consumption even if the mobile phone is set as a device capable of answering a call from a front door slave unit. It is an object.

A so-called smartphone is applied to the mobile phone 2, and a call / answer is performed by SIP communication with the intercom device. It also has a GPS reception function, and has a function of receiving a GPS signal and grasping its own position.
Further, the area information storage unit 21 that stores a specific area including the position of the living room master unit 5, the position determination unit 22 that determines whether the current position is inside or outside the specific area, and the determination that the current position is inside the specific area. Then, it has a register processing unit 23 that periodically performs registration processing (IP address registration processing) on the living room master unit 5. The area information storage unit 21, the position determination unit 22, and the register processing unit 23 are set by installing predetermined application software on the mobile phone 2.

FIG. 3 shows a block diagram of the communication adapter 3. The communication adapter 3 includes a first communication interface (first communication IF) 31 that communicates with the room master unit 5, a second communication interface (second communication IF) 32 that connects to the network N, and the room master unit 5 and the mobile phone 2. It includes a memory 33 for storing information, a communication adapter CPU 34 for controlling the communication adapter 3, and the like.
The communication adapter CPU 34 has a function of issuing a push request to periodically execute a process (connection maintenance process) for maintaining a connection with the room master unit 5 to the mobile phone 2.
still. The connection maintenance process is a register process in which the mobile phone 2 notifies the room master unit 5 of the IP address.

The management server 6 manages the communication of the mobile phone 2, and when the push request is output from the communication adapter 3, recognizes the push request and requests the mobile phone 2 to perform register processing. Specifically, a VoIP PUSH request is issued from the communication adapter 3, and the management server 6 recognizing this request performs VoIP PUSH to the mobile phone 2. In response to this VoIP PUSH, the mobile phone 2 performs register processing via the living room master unit 5. As a result, the living room master unit 5 is maintained as the SIP client of the mobile phone 2.

The intercom system configured as described above operates as follows. Since the call / answer operation of the intercom device 1 including the entrance slave unit 4 and the living room master unit 5, the imaging operation of the camera 42, the display operation of the living room master unit 5, etc. are the same as before, the description is omitted here. The operation of maintaining the connection to the living room master unit 5 of the mobile phone 2 will be mainly described.
In order to perform the operation of notifying the mobile phone 2 from the living room master unit 5 of the call occurrence from the entrance slave unit 4 and making a call by SIP communication, the IP address of the mobile phone 2 that is frequently changed is used as the living room parent. It is necessary to register in the machine 5, and the registration of the living room master machine 5 as a SIP client is maintained by carrying out the registration on a regular basis.

This connection maintenance operation differs inside and outside a specific area including the position of the living room master unit 5, and is specifically performed as follows.
First, a specific area is set as follows. A GPS signal is received with the mobile phone 2 placed near the room master unit 5, and the received position information of the mobile phone 2 is registered as the position information of the room master unit 5. An area that is a certain distance (for example, 20 meters) or less with respect to this registered position, or a specific area including the registered position (for example, an area that matches the shape of the site of the home) is registered in the area information storage unit 21. , This area is a specific area.

The mobile phone 2 grasps its own position from a GPS signal that is constantly being received, and the position determination unit 22 determines whether this position is inside or outside a specific area. As a result of the determination in this way, if it is determined that the area is within a specific area, for example, the register processing unit 23 performs register processing at intervals of 10 seconds (first time interval) and performs IP address registration processing. The registration signal is transmitted to the living room master unit 5 via the network N and the communication adapter 3, and the latest IP address of the mobile phone 2 is registered in the living room master unit 5. The first time interval for register processing at this time does not have to be 10 seconds, and may be as long as about 30 seconds.

On the other hand, if it is determined that the area is outside the specific area, the mobile phone 2 does not perform the installation maintenance process under its own control. Instead, the connection maintenance process is performed under the control of the communication adapter 3.
The communication adapter 3 constantly outputs a signal requesting connection maintenance processing to the mobile phone 2 at intervals of 10 minutes (second time interval), that is, a VoIP PUSH request, and the management server 6 recognizes this request. Then, VoIP PUSH is formed from the management server 6 to the mobile phone 2.
When the mobile phone 2 is outside the specific area, the register processing unit 23 receives the VoIP PUSH, performs the connection maintenance process, and notifies the living room master unit 5 of the IP address. The second time interval required by the communication adapter 3 for VoIP is not limited to 10 minutes and may be, for example, 5 minutes, but a longer interval is preferable because it can reduce the power consumption of the mobile phone 2.

In this way, the connection between the mobile phone 2 and the room master unit 5 is maintained, and when a call is received, the ringing tone is sounded by the room master unit 5, and the room master unit 5 via the communication adapter 3 and the network N. The call is notified to the mobile phone 2. When the mobile phone 2 that receives this notification is operated to make a call, a call path is formed between the living room master unit 5 and the mobile phone 2, that is, between the mobile phone 2 and the entrance slave unit 4, and the mobile phone 2 is formed. It is possible to make a call between the resident who owns the mobile phone and the visitor.
Further, in response to the call operation of the mobile phone 2, the captured image of the camera 42 is transmitted to the mobile phone 2 by the same route as the notification of the call, and the resident can confirm the visitor by the image.

In this way, when the mobile phone 2 is in a specific area including the installation position of the room master unit 5, a person carrying the mobile phone 2 in order to carry out the connection maintenance process with the room master unit 5 relatively frequently. When the user is at or near his / her home, he / she can smoothly communicate with the room master unit 5 and can smoothly answer a visitor's call or the like. On the other hand, when the mobile phone 2 leaves the specific area due to going out or the like, the mobile phone 2 does not perform the connection maintenance process under its own control, so that the power consumption of the mobile phone 2 can be suppressed.
Further, when the mobile phone 2 is located outside the specific area, the connection maintenance process is periodically performed under the control of the communication adapter 3, so that the connection with the living room master unit 5 is continued. In addition, at that time, power consumption can be reduced because the connection is maintained by starting with a signal from the outside.
Further, since the living room master unit 5 communicates with the mobile phone 2 via the communication adapter 3, it is sufficient if it can communicate with the communication adapter 3 and does not directly communicate with the mobile phone 2, so that the communication interface can be simply configured.

In the above embodiment, the specific area is set based on the position of the living room master unit 5, but the specific area may be set based on the position of the entrance slave unit 4 or the intermediate position between the two. You may set it.
Further, although the living room master unit 5 communicates with the mobile phone 2 via the communication adapter 3, it may communicate directly with the network N via a wireless router or the like without going through the communication adapter 3.
Further, although the area information storage unit 21 and the position determination unit 22 are provided in the mobile phone 2, the management server 6 may be provided and the mobile phone 2 may be allowed to perform only register processing.
