COMMUNICATION CONTROL SYSTEM AND METHOD FOR CONTROLLING COMMUNAL ENTRANCE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication control technology for entrance control of a common entrance, and more particularly, to a communication control method and system for entrance control using a communication network corresponding to a user's incoming call.

Recently, apartments or apartment buildings have been used a lot. Such apartments include, for example, apartments, officetels, villas and townhouses. In general, these apartments share a common entrance by unit, and for the sake of security, an interphone system is constructed to open and close the common entrance individually in each household or office.

Such an interphone system is part of a home automation system such as a home automation (HA) system or a home network (HN) system, and provides a voice or video call between a visitor and a user using a common door phone, a HA generation device, or an HN generation device. do. When a visitor enters a household identification code such as Dong Ho Lake into the common entrance phone or lobby phone, communication is connected with the household device, and the user opens and closes the common entrance door after checking the visitor.

However, the existing common hall phone or lobby phone has a problem in applying a dedicated communication method for each manufacturer that can communicate only with the HN generation device in the generation home automation system or home network system. For example, if a householder breaks down, the call between the visitor or guard room and householder becomes impossible. In addition, in the event of a failure, users are inevitably forced to purchase expensive home automation systems or home-network-only generation devices of the same manufacturer. In addition, if the generation device manufacturer discontinued the corresponding generation device or the manufacturer disappears, the user is in a very difficult situation in which the user cannot use the network system because standardization is not performed.

In addition, the main building, which was built before the application of the existing automatic doors and common entrance telephones, is usually composed of only a voice call BUS wiring (CPEV CABLE), not a video phone. In this case, in order to construct a new automatic door and home network system, it is too expensive to apply the existing technology. This is because a new video line is constructed.

As another conventional technology, a method of connecting a PSTN common entrance telephone to a PSTN network has been developed by including a PSTN telephone function in a common entrance telephone. This is a PSTN telephone access control system in which a visitor makes a voice call by making a call from a PSTN public entrance telephone to a home telephone and controls an automatic door using a telephone DTMF signal. However, the method of applying PSTN phone to the common door phone is not only impossible for video call but also expensive communication cost compared to the data communication through packet communication because of the PSTN common door phone device for voice communication using only analog circuit switching method. There is a problem.

Hereinafter, with reference to the accompanying drawings will be described embodiments of the present invention;

The present invention provides a communication control method and system for entrance control. The present invention can be suitably applied to the so-called common buildings using a common entrance, such as apartments, officetels, townhouses, villas. The present invention includes a switch that is connected to a plurality of communication networks and performs a communication connection according to the setting of a common entrance telephone and a user telephone of each generation. In particular, the exchange of the present invention operates to use the same communication network as the communication network to which the user telephone belongs, in the communication connection from the common entrance telephone to the user telephone. This enables very low communication costs and even free calls.

Such a communication system provides various advantages in addition to the communication fee. For example, the system of the present invention can be built at a relatively low price, which is that it can be applied casually to the existing base building. The system of the present invention thus constructed provides a voice call as well as a video call according to a communication network and a communication device, and in some cases, a user can identify a visitor using a mobile phone such as a mobile phone.

Referring to the drawings, the communication control system for access control of the common entrance according to the preferred embodiment of the present invention is connected to the common entrance telephone 10, the common entrance telephone 10 and the switch 20 connected to a plurality of communication networks Include.

The exchange 20 stores a plurality of household identification codes and at least one telephone number of a user corresponding to each household identification code. Here, at least one telephone number of the user is a telephone of the user registered by the user, and includes an internet video terminal 41, an internet voice / video terminal 42, a trunk line telephone 43, a mobile phone 44, and the like. . The telephones of these users are connected to a plurality of communication networks 30.

The plurality of communication networks 30 includes a VoIP communication network 31, a trunk line telephone network 32, and a mobile communication network 33 of at least one internet network. The trunk line telephone network may be a public switched telephone network (PSTN) that includes both so-called analog and digital switching. In addition, a router 51 and a hub 52 may be employed for shared connection of multiple devices.

Switch 20 according to a preferred embodiment of the present invention is a kind of intelligent private branch eXchange (PBX), preferably stores the necessary information connected to the VoIP network and establishes a communication connection in a manner set by the built-in alias program. To perform the operation.

For example, the exchange 20 of the present invention stores at least a household identification code such as a house number and a user telephone number corresponding to each household identification code. The user's telephone number may be at least one registered by the user, and a plurality of telephone numbers stored by each user are ranked.

When the visitor makes a household call by inputting a household identification code into the common door phone 10, the switch 20 receives the household identification code and performs a communication connection in a set manner. The communication connection first performs the communication connection by selecting the highest priority according to the set phone number priority among the user's phone numbers corresponding to the received household identification code.

As an example of the communication connection, the switch 20 determines the telephone number type from the telephone number of the telecommunications company mapped with each generation telephone number, searches for the telephone number waiting for communication among the plurality of telephone numbers, and the telephone number (eg By selecting Powercom video1), a VoIP video call path can be formed from the telephone number using a soft switch and a mobile communication video exchange.

In this case, the exchange preferably performs a communication connection through the same communication network as the selected highest priority telephone number of the user. For example, in the case of a VoIP phone of a specific telecommunication company of a receiver, an outgoing call using the same telecommunication company is established by setting up an outgoing call using the same telecommunication company. As such, detection and selection of the same communication network and the same communication company are determined from the user's incoming telephone number as shown in FIGS. 2 to 4.

In addition, if the communication connection to the selected highest priority telephone number is not possible or is not connected for a predetermined time, the communication connection may be sequentially performed to the next priority telephone number according to the set priority. For example, when the telephone of the user selected as the top priority is busy, the caller generates a call back to the next registered phone number.

It may further include a common door automatic switchgear which operates according to a predetermined signal from the user phone during a call between the common door phone 10 and the user phone of the selected phone number. This can be integrated or separately configured in the common door phone 10 and DTMF receiver for detecting the DTMF signal specified for automatic door opening use in the common door phone (10). Therefore, when the user transmits the DTMF signal by pressing the button key assigned to the automatic door opening, the DTMF receiver detects this and the automatic problem communication unit transmits the open signal to the automatic door to open the common entrance. This can be done by assigning a key for generating an automatic door opening DTMF signal to any button key among ten keys of the user's telephone.

In addition, as described above, a communication connection that may be made in a preferred embodiment of the present invention may include a voice call and a video call. Accordingly, the common entrance telephone 10 may be provided with elements for a video call, such as a video camera.

Preferably, as can be seen in Figure 1, the common entrance telephone 10 and the switch 20 may be connected to the guard room telephone 60 and the internal network. Accordingly, when the guard room call button assigned to the common entrance phone 10 is pressed, the switch 20 connects the common entrance phone 10 and the guard room phone 60 to make an internal call through the internal network.

In addition, the common door phone 10 is assigned a button key for emergency call so that when there is an emergency call input, the emergency call signal can be transmitted to the guard room, management room, and the like.

With reference to Figures 1 to 7 will be described in detail the operational flow of the communication control method and system for access control of the entrance hall according to an embodiment of the present invention. Here, the description will focus on the communication connection between the common hall phone 10 and the user phone for the visitor confirmation.

First, referring to FIGS. 1 and 6, when the visitor inputs the household identification code through the ten key button of the common door phone 10, the switch 20 receives this (step 10 (S10)).

In step 20 (S20), the switch 20 selects the highest priority telephone number according to the telephone number ranking among the stored user telephone numbers corresponding to the received household identification code.

If the phone number is selected, the process proceeds to step 30 (S30), and performs a communication connection. The communication connection is performed by selecting from a plurality of communication networks 30 according to the station number of the selected telephone number. For example, as shown in Figure 7 it can be made in a way to find and connect to the communication network corresponding to the station number.

As shown in FIG. 7, it may be performed through the sequential detection of the station number as in steps 311 (S311) to 316 (S316), and alternatively, a table for the communication network corresponding to the station number is directly stored in the switch 20. Afterwards, a direct connection can be made to the communication network corresponding to the station number. Either way, the tables shown in Figs. 3 to 5 can be used for the connection of the preferred communication network according to the station number. FIG. 3 is a block diagram of an IP, domain, and port configuration of each telecommunication company to register with each telecommunication company according to an exemplary embodiment of the present invention, and an outbound network ID for tying each outbound name and each outbound name of each telecommunication company. 4 is a configuration diagram of mapping each telephone number registered in the switch 20 and the outbound communication network ID according to the preferred embodiment of the present invention. 5 is a configuration diagram of mapping a household identification code (generation number) and an ID of an outbound communication network used when making a call to a selected user telephone number and a user telephone number according to an exemplary embodiment of the present invention.

6, it is determined that the highest priority telephone number of the selected user cannot communicate with the user and proceeds to the next step. In this case, there may be a case where the number is not received, busy, or a normal call is established but there is no reception for the number. At this time, for example, when a call cannot be made (outgoing call establishment) or a call is made, a decision may be made immediately. In addition, when a call is made but there is no reception for the corresponding number, a decision can be made after a set time (for example, 10 seconds) (step 40 (S40)).

If it is determined in step 40 (S40) that the connection is not possible, proceed to step 50 (S50) to check whether there is a stored next-order phone number.

If there is a stored next-order phone number, the process proceeds to step 60 (S60) to perform a communication connection to the number. In the above-described communication connection, a connection is selected from a plurality of communication networks 30 as in step 30 (S30) according to the station number of the selected telephone number. In this case as well, the flow shown in FIG. 7 searches for the same communication network as the corresponding phone number and performs a communication connection.

Although not shown in the flowcharts of FIGS. 6 and 7, when the user generates a corresponding DTMF signal by pressing a button key corresponding to the common door opening signal during a call, the DTMF receiver installed on the common entrance telephone 10 receives the same. The automatic door communication unit transmits an open signal to open the door. In addition, when calling the guard room from the common entrance telephone 10, communication is connected through the internal network. In addition, when pressing the emergency call button key provided in the common door phone 10, the emergency call signal is transmitted to the connected guard room or management room.

Preferably, both the public hall telephone 10 and the user's selected telephone number use a VoIP communication network. In this case, the communication cost will be free or near free, and both voice and video calls will be available.

However, there may be a case where the connection of the same communication network is not established or another communication network must be used. For example, if the selected user telephone number is a trunk line or a mobile communication network, use of the cheapest communication network should be considered. Even in this case, operations such as opening of the common entrance door or emergency call may be applied in the same manner as described above.

8 and 9 show an example of applying the system of the present invention to a home network system or a home automation system as another embodiment of the present invention. 10 is an exemplary view showing a network connection of user telephones that can be applied to the present invention.

For example, as shown in FIG. 8, the user's generation device 70 is connected to the switch 20, the common entrance telephone 10, the security office telephone, and the like through a network. In this case, communication is connected between the common hall phone 10 and the household device 70 of the user, but when the user attempts an external outgoing call through the household device 70, the switch 20 receives the incoming telephone number. The communication number can be performed through the same communication network by using the station number of. In this case, it may be more effective when the generation device 70 is a VoIP phone.

In addition, FIG. 9 illustrates a case in which a generation device 80 including the configuration of FIG. 1 is connected to the switch 20, the common entrance telephone 10, and the security office telephone through a home network. In the example of Figure 9 can be used in combination with the configuration of Figure 1 and 8, there is an advantage that can be additionally applied to the existing building.

Application example

The following describes an example of the use of the present invention. It should be noted that other terms may apply to the same or similar elements in the following detailed description. For example, a common entrance telephone may be described or illustrated as a lobby phone. In addition, the user phone may be represented by a generation unit or a generation communication device. The trunk line telephone network may be used as a term such as a PSTN network, and the trunk line telephone is a PSTN telephone. In addition, the household identification code can be expressed as the same number. A guard room telephone can also be expressed as a guard machine.

This is the case that VoIP network network is composed of VoIP public hall telephone, VoIP guard room telephone and exchange.

When the VoIP security room telephone call button is operated in the VoIP common door phone, the switch receives the button signal and the built-in Alias program converts the VoIP security room telephone call button signal into the extension number. In other words, the call is made from the VoIP guarded room telephone connected to the VoIP network to form an internal VoIP video call or an VoIP voice call.

In addition, when the security door needs to be opened, the Ten Door Button for Automatic Door Opening of the VoIP Security Office Phone is generated during the video call or voice call with the VoIP Common Door Phone and the VoIP Security Room Phone. It transmits automatic door opening digital control signal to VoIP common entrance telephone through VoIP network of public switching center, and VoIP public entrance telephone opens the automatic door.

In particular, in the case of using DTMF signals, when a tenkey button designated for automatic door opening of a VoIP guard room telephone is operated during a video call or a voice call with a VoIP common door telephone, a DTMF signal is generated using the VoIP guard room telephone to generate a DTMF signal. Automatic door opening DTMF control signal is transmitted to the phone, and VoIP common door phone recognizes the DTMF signal and opens the automatic door.

In addition, the call and automatic door control between the VoIP common entrance telephone and the generation VoIP communication device can be provided to the switch. Voice phone 1, K voice phone 2, B voice phone 1, B voice phone 2, etc.) are selectively installed and used according to the user's characteristics. At this time, the exchange stores the household identification code, such as the Dong Ho, in association with the telephone numbers of the home communication device. The exchange is able to check the communication usage status of a plurality of telephone numbers of users stored in the formation of a call path according to a program set when performing a call connection, and select and connect a telephone number that is waiting for communication. In addition, by designating a telephone number of a flat rate, it is also possible to select a connection according to a charge according to a fee, for example, using an S flat-rate video phone 1 or an S flat-rate video phone 2. In this case, since it is also possible to form a call path using the telephone number of the VoIP communication company, such as the VoIP communication company to which each generation communication device belongs, at the exchange, a free call service in the same VoIP communication network can be used.

Therefore, if the user's phone is a VoIP video communication device (VoIP video phone, VoIP HN generation device) connected to the VoIP communication network of the Internet network, when the user enters the number of the call in the VoIP common phone, the switch receives the button signal and Convert number to phone number. Followed by an exchanger The phone number of the user designated as the top priority and the telecommunications company mapped to it are determined and connected. In this case, a method of searching for a telephone number waiting for communication rather than a telephone number ranking may be applied.

In addition, when the user telephone is a VoIP telephone connected to the VoIP communication network, the voice call connection may be performed through the soft switch.

In addition, if you operate the Ten Door Button for automatic door opening during a call with a user VoIP communication device connected to a VoIP common door phone and a VoIP communication network, an automatic door opening digital control signal is generated, and the automatic door opening digital control signal is transmitted to the VoIP common door phone. The common entrance telephone receives the digital control signal and opens the automatic door.

In addition, if you operate a ten key button specified for automatic door opening of a user's VoIP communication device during a call with a user's VoIP communication device connected to a VoIP common door phone and a VoIP communication network, a DTMF signal is generated and an automatic door opening DTMF control signal to the VoIP common door phone. The VoIP public hall phone recognizes the DTMF signal and opens the automatic door.

When the user's telephone is a PSTN telephone connected to the PSTN communication network, when the user enters the call number into the VoIP public entrance telephone, the switch receives the button signal and converts the call number into a telephone number in the alias program. Subsequently, at the exchange, a VoIP video call path is formed using a soft switch and a PSTN exchange. Therefore, the voice call is performed.

In addition, if you operate the TenKey button designated for automatic door opening during a call with a VoIP common door phone and a generation PSTN phone, a DTMF signal is generated to transmit the automatic door opening DTMF control signal to the VoIP common door phone, and the VoIP common door phone sends a DTMF signal. Recognize and open the automatic door.

If the user's phone is a mobile phone of mobile communication network, if the user enters the call number into the VoIP public entrance telephone, the switch receives the button signal, the alias program converts the call number to the phone number, and the switch is mapped to each generation phone number. The phone number of the carrier determines the type of phone number, searches for the waiting phone number among a plurality of phone numbers, selects the phone number (e.g. Skype mobile communication service) from the exchange, and selects the soft switch and mobile communication from the phone number. Using the exchange, a VoIP voice call path is formed.

In addition, if you operate the Ten Key button designated for automatic door opening during a call with a VoIP common door phone and a mobile communication network mobile phone, DTMF signal is generated, and the automatic door opening DTMF control signal is transmitted to the VoIP common door phone, and the VoIP common door phone sends the DTMF signal. Recognize and open the automatic door.

If the user's phone is a mobile video network mobile phone, when the user enters the call number into the VoIP public entrance telephone, the switch receives the button signal and converts the call number to the phone number in the alias program, and the switch maps the phone number to each household number. The phone number of the telecommunication company determines the type of phone number, searches for the waiting phone number among a plurality of phone numbers, selects a phone number (eg, PowerCom Video 1) on the exchange, and selects the soft switch and the mobile communication video from the phone number. A VoIP video call path is formed using an exchange.

In addition, if you operate the Ten Key button designated for automatic door opening during a call with a VoIP common door phone and a mobile communication network mobile phone, DTMF signal is generated, and the automatic door opening DTMF control signal is transmitted to the VoIP common door phone, and the VoIP common door phone sends the DTMF signal. Recognize and open the automatic door.

Alternatively, the telephone number may be directly connected to the mobile communication switchboard of the mobile communication base station using the Internet.

In addition, other applications include the HN generation and VoIP common telephones, video calls, and automatic door opening. In general, the HN generation unit can communicate with the VoIP common entrance telephone.

Therefore, when the call number is input to the VoIP common door phone, the caller receives a button signal and the alias program converts the call number to an extension number. To determine the type of number, search for the waiting phone number among multiple phone numbers, select the phone number (ex: Powercom Video 1) from the exchange, and use the soft switch and the mobile communication video exchange from the phone number to make VoIP video. It will form a currency path.

In addition, if you operate a button designated for automatic door opening during a call with a VoIP common door phone and a generation HN generation device, it generates a DTMF signal, transmits an automatic door opening DTMF control signal to a VoIP common door phone, and the VoIP common door phone recognizes a DTMF signal. Open the automatic door.

In addition, by connecting an internal communication device such as an HN generation device to the extension communication network of the exchange, it is possible to make a call with an external communication device, and it is also possible to use a switch to reduce the communication cost. That is, in each generation HN generation unit and an external communication device and a call path, a plurality of telephone numbers for wired telephones (e.g., Skype fixed amount first, Skype fixed amount two) and a plurality of mobile numbers for mobile communication (e.g. Skype) Add mobile telecommunications stipulation 1, skype mobile telecommunications stipulation 2) and a number of country-specific telephone numbers (e.g., Skype America 1, Skype America 2, Skype Japan 1, Skype Japan 2, Skype Taiwan 1, Skype Taiwan 2, etc.) Connect to VoIP network of Internet network. The exchanger connects an extension communication device, such as each generation HN generation device, to the VoIP extension network, and uses the number of the front end number of the telephone number input from the communication device for the extension (wired telephone or mobile communication or The US telephone or Japanese telephone is judged, and the type of telephone number to be used is determined using the determined communication device information (wired telephone or mobile telephone or American telephone or Japanese telephone). Subsequently, the exchange checks the use of the determined number of telephone numbers, and it is also possible to select a telephone number which is not in use among the checked multiple telephone numbers and use it as an outgoing telephone number. Fare reduction is possible using the operator's country-specific gateway.

Therefore, it is possible to reduce the communication cost by jointly using the telephone number of the exchange when each household in the apartment complex makes an outgoing call, and it is possible to receive a telephone call in each household using the individual telephone number.

In addition, in the automatic door open control signal, there are VoIP communication devices (VoIP video phone, VoIP HN generation device, VoIP phone) operated by various VoIP operators in the generation, and also analog PSTN communication network PSTN phone. There may be generations that use only mobile phones, not mobile phones. In this case, in various types of communication devices, the VoIP common door phone can receive the automatic door opening digital control signal in accordance with a specific VoIP communication network VoIP communication device. However, there are too many VoIP providers, and there are many difficulties in matching protocols due to differences in hardware and protocols. Therefore, it is good to use the automatic door opening digital signal by matching the protocol of VoIP communication device (VoIP video phone, VoIP phone) to each VoIP communication network operated by various VoIP providers. VoIP communication network operated by VoIP service provider In-band DTMF signal is transmitted from VoIP communication device (VoIP video phone, VoIP phone) to VoIP common phone, and the VoIP door phone DTMF receiver receives In-band DTMF signal to receive automatic door. It is better to control it.

In addition, the PSTN telephone, which is an analog communication device, receives DTMF signals (1 ~ 9, *, #) generated by the analog PSTN telephone from the DTMF receiver of the VoIP common phone. The VoIP shared phone is a digital control signal and an analog DTMF control signal. As a communication device that can receive (1 ~ 9, *, #) at the same time, it has high adaptability, and can act as a communication device that can receive automatic door open control signal from all communication devices in the home.

In addition, automatic door opening is possible in HA generation and HN generation, which include DTMF signals in common, and automatic door opening in HN generation.

In addition, the mobile phone can transmit the in-band DTMF signal to the VoIP common entrance telephone to receive the DTMF signal from the VoIP common entrance telephone DTMF receiver and control the automatic door.

In addition, the DTMF receiver may detect the DTMF signal by receiving the drawing signal of the NETWORK IC of the VoIP common door phone, or may detect the DTMF signal by receiving the analog signal of the speaker.

In addition, in the digital communication, DTMF signal transmission includes an out-band method for separately transmitting a voice signal and a DTMF signal, an RTP-2833 method, and an in-band method for transmitting a voice signal and a DTMF signal together.

Therefore, the DTMF receiver or IP IVR which recognizes the DTMF signal is included in the exchange, so that the receiver monitors the call line of the receiver during the call with the VoIP common phone, the VoIP video phone, or the HN generation device or the VoIP phone or the mobile phone or the PSTN phone. Detects the DTMF sound (eg * or # or * #) specified by the automatic door opening signal generated by operating the button, converts it into a digital signal, and transmits it to the VoIP public hall phone, which opens the automatic door. Also good.

In addition, the DTMF receiver or IP IVR (Interactive Voice Response) function is included in the backbone soft switch to monitor the call line of the receiver, and the DTMF tone (eg * or # or * #) May be detected and converted into a digital signal for transmission to a VoIP public entrance telephone, and the VoIP public entrance telephone may open the automatic door.

In addition, the DTMF receiver may be configured in the form of a physical DTMF chip or DTMF board.

In addition, in the case of configuring a VoIP network of a public-only complex, the VoIP server includes an alias program only in the VoIP server. When the tenant operates a call button or a VoIP security room telephone call button on the VoIP common entrance telephone, the button signal is transmitted. Only the VoIP server transmits the call button signal of the household call number or VoIP security room telephone device to the telephone number or private IP or MAC ADDRESS of each generation communication device or public VoIP device. It is possible.

Alternatively, by including the Alias program in the VoIP public hall phone, if the tenant operates the call button or the VoIP guard room phone call button in the VoIP public hall phone, each generation communication device or public VoIP communication in the VoIP public hall phone It converts the phone number or private IP or MAC address of the device and transmits it to the VoIP server only, the internal call is carried out only in the VoIP server, or each generation communication device and the call can be made by using the soft switch in the VoIP server. It is possible to do so.
