Description

  The present invention relates to a gateway device that can control home appliances and the like under a command from a remote place.

  In recent years, with the widespread use of multifunctional devices such as smartphones, there has been a rapid increase in the need to remotely control electrical appliances such as home air conditioners and recorders using such multifunctional devices. For example, there is a need to turn on the cooling in advance or start to boil the bath when returning home. Currently, in some electric appliances such as air conditioners, remote control has begun to be realized by using dedicated applications (programs) that operate on multifunction devices and personal computers.

  Currently implemented remote control of home appliances is basically realized by data communication via the Internet. At this time, an instruction code for controlling the appliance is flowing through an open network, and there is a risk of eavesdropping or modification, which presents a security problem.

  Standardization of such appliance control as an energy management system represented by HEMS (Home Energy Management System) for home use, BEMS (Building Energy Management System) for commercial buildings, and FEMS (Factory Energy Management System) for factories Activities are progressing. For example, in HEMS, a standard called ECHONETLite (registered trademark) is in progress. However, at present, there is a need for one app that corresponds to each type of appliance, control machine product, and the like. In the future, although it is expected that products from the same manufacturer will be improved so that multiple products can be controlled with one application, the manufacturers of all products installed in houses and offices will be unified. Is difficult in practice. For this reason, as the number of products that can be controlled increases and the need for management increases, there is a concern that the management of apps for the control becomes complicated. In addition, it will be difficult for manufacturers to link different products.

  Furthermore, the use of users who are not high in information literacy becomes a problem in that multi-function devices are assumed in the first place. Furthermore, if application management for each individual manufacturer is required, it will be a big barrier to use.

  Furthermore, the control depending on the application depends on the state of the multi-function device that executes the application. Current multi-function devices always have a problem of running out of battery. If only multi-function devices are assumed, remote control cannot be performed in an emergency.

  On the other hand, as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2012-124567), a method using communication using a telephone network has been proposed. A home gateway (HGW) device connected to the public telephone network receives a predetermined control number as a subaddress included in the SIP message header transmitted from the public telephone network. Each control number corresponds to a device connected to the home gateway device and a command to those devices (Patent Document 1, FIG. 8, etc.), and the home gateway sets a set value such as a device power supply or a sensor on / off according to an instruction by a subaddress. Make changes. Since communication is performed via a public telephone network, it is difficult to be modified and security is high compared to conventional application-based processing that is exchanged using the standard HTTP protocol of the Internet.

  On the other hand, a communication device such as a home gateway is provided with a Java (registered trademark) virtual machine (JVM) function. In the communication apparatus having this JVM, in addition to the native function that is inherent to the communication apparatus, various functions are added by a bundle that is application software executed in the Java area, and the functions are further updated. be able to. That is, new functions corresponding to the advancement of network technology and the addition of services can be added by being distributed and updated as bundles. As a result, it is often possible to cope with the development of a bundle, which is software, without re-developing the communication device from hardware having a necessary Native function. HGW reduces the number of cases where devices need to be replaced, and makes it easier for users in individual households to use them continuously. In addition, the latest functions can be quickly spread for a service provider. Furthermore, development costs can be reduced. Furthermore, it is easy to fix errors and update for security.

  If you try to run the bundle on the JVM, the required specifications such as CPU and memory will be higher than if you implement the same function with the Native function. For this reason, only some functions such as GUI functions and UPnP functions were initially provided as bundles. However, as the processing power of devices improves with the times, more functions can be provided as bundles on the JVM.

  For example, Non-Patent Documents 1 and 2 include the name of FLET'S JOINT (registered trademark) and Java in the HGW installed in each home connected to the next generation network (NGN) configured with IPv6. A method to provide and add functionality is presented.

  Here, a technology called the Open Services Gateway Initiative (OSGi) is used. A bundle called a center system installed on the network is registered so that the bundle can be distributed. Gateways, routers, AV equipment, automobiles, mobile phones, and other communication devices that use this bundle have a function unit called OSGi framework on the JVM. The OSGi framework provides basic functions such as downloading, starting and stopping of each bundle, inter-bundle service, security mechanism, event processing, etc., and each bundle runs on this OSGi framework that functions on the JVM. To do. Functions commonly used in the bundle are standardized as a basic service bundle, and a bundle developed according to the use of the device is separately called an application bundle. Both bundles can be provided from the center system.

  Patent Document 2 discloses that a server application program and a client application program are collectively delivered to a server device that distributes an application program, and the client application program stored in the storage unit by the server device is stored in the client. It describes that the step of transmitting to the terminal is executed. This is the disclosure of the bundle distribution mechanism itself.

  However, there are a wide variety of home appliances, and if it is attempted to deal with devices of various manufacturers using only the Native function as in Patent Document 1, it is necessary to update the firmware repeatedly, which is difficult in terms of device management. It will no longer be for users with low information literacy.

  Accordingly, an object of the present invention is to provide a remote operation environment that allows a user to easily cope with the diversification and complexity of home appliances.

This invention
At least one gateway device having an OSGi framework and connected to at least one control target terminal via a subordinate local area network;
A system having a bundle distribution server that distributes a bundle that operates on the OSGi framework to the gateway device,
The gateway device is
An accommodation device database that associates the designation of the device included in the control signal designated as the subaddress of the incoming call from the control execution terminal connected to the external network and the address of the control target terminal;
A control signal database associating the designation of control included in the control signal with the control content for the control target terminal;
Have
As a native function of the device itself,
A SIP function unit that accepts call processing and delivers the subaddress as a control signal when the incoming call includes a subaddress;
In accordance with the control signal delivered from the SIP function unit, the address of the control target terminal designated in the control signal is called with reference to the accommodated device database, and the control signal is referred to the control signal database. A storage device control unit that calls the control content to the control target terminal specified in the above, and passes the address and the control content to the OSGi framework;
Have
As a bundle function implemented on the OSGi framework,
Having a terminal control bundle that transmits a control command corresponding to the control content, with the address passed from the accommodation device control unit as a destination,
The bundle distribution server
Command bundle distribution means for transmitting the terminal control bundle to the gateway device;
The above-described problem has been solved by the home appliance control method providing system.

  The signal system itself can be made common, and the contents designated with reference to the control signal database can be sent to the terminal control bundle, thereby supporting various control target terminals. By sharing such signals, matters that the user must remember can be suppressed. For this reason, it is not limited to multi-function devices. From a general push-type phone, you can enter “*” after the phone number of your home or office, and then send a signal with the same specifications. Is possible.

  Another element that makes this possible is a terminal control bundle that is implemented as a bundle on the OSGi framework. Even if the control signal database is used to turn the power on and off and translate it into other actual operations, it cannot be converted by itself unless the specifications of each manufacturer are completely unified. However, the terminal control bundle whose contents can be updated from the bundle distribution server is responsible for sending the final signal to each control target terminal, so that a variety of OSGi framework technologies can be used from the bundle distribution server. Expansion to new products and expansion to products that will be released later can be updated sequentially.

  According to the present invention, when a user with low information literacy is used, it is possible to perform control by a sub-address that can use the public telephone network while ensuring flexibility to cope with an increasing number of electric appliances.

  Hereinafter, the present invention will be described in detail with reference to embodiments. The present invention includes a gateway device such as a home gateway that handles communication such as call processing and Internet connection, and a bundle distribution server that can add or modify functions by transmitting a bundle to the gateway device. It is.

The relationship of the system including the gateway apparatus 11 and the bundle distribution server 39 for implementing the present invention is shown in FIG.
The gateway device 11 has a Native function 13 that is mounted on a NativeOS (not shown) and operates on an actual CPU. In addition, the gateway device 11 has a JVM (Java Virtual Machine) 14 which is a virtual machine. The JVM 14 is provided with an OSGi framework 15 to which a software module called a bundle (17, 18,...) Can be dynamically added. When the JVM 14 cooperates with the Native function 13, data and instructions are mutually exchanged via JNI (Java Native Interface) 16 which is a set of API (Application Programming Interface) for using the other function from one. . Furthermore, each functional unit and a storage unit (not shown) accessed by the JVM 14 are included.

  The gateway device 11 is distributed with bundles (17, 18,...) From a bundle distribution server 39 provided in the provider network 32 described later. Of these bundles, as a terminal control bundle 17 to be described later or a data group attached thereto, an instruction conforming to the standard of the control target terminal 41 to be described later is recorded and executed.

  The gateway device 11 operates as a gateway that relays communication between an internal network 30 such as a home network or a business office network and other external networks 31. Although omitted in the figure, the native function 13 or bundle has basic functions such as a DHCP server function and a router function for operating as a router.

  The internal network 30 is connected by wire or wirelessly, and one or more control target terminals 41 (41a, 41b, 41c, 41d...) That are targets for realizing remote control according to the present invention can communicate with the gateway device 11. It is connected to the. The control target terminal 41 is an electrical appliance having a wired or wireless communication interface. Here, the air conditioner 41a, the refrigerator 41b, the microwave oven 41c, and the water heater 41d are cited as examples, but the invention is not limited thereto. Any electrical appliance that is in demand, such as a component, a radio server, a personal computer, or a tablet, that performs power on / off, setting change, or operation setting from a remote location can be used as the object of the present invention.

  On the other hand, the external network 31 is connected to a carrier network 32 managed by a telecommunications carrier. Furthermore, a mobile communication network 33 provided by a mobile phone company, a legacy telephone network 34, which is a conventional fixed telephone network, and an IP using technology based on VoIP (Voice over Internet Protocol) via the operator network 32. It is connected to the telephone network 35 and the like. Examples of the control execution terminal 37 that is connected to the external network 31 and from which a user transmits a control instruction include the following media. For the mobile communication network 33, a multi-function device 37a such as a smartphone, a tablet, or a fablet that can be connected by a mobile communication system is exemplified. For the legacy telephone network 34, there are public telephones and fixed telephones 37b such as wired subscriber telephones installed at homes and offices. For the IP telephone network 35, a terminal similar to the above-described multi-function device 37a connected by data communication via a mobile communication system, an IP telephone 37c such as a VoIP telephone adapter for connecting a fixed telephone to an optical fiber network, etc. Is mentioned. Note that these may overlap.

  The gateway device 11 constituting the present invention transmits a command to the control target terminal 41 in accordance with the subaddress included in the incoming call from the control execution terminal 37 connected to the external network 31 in the above environment. A sub-address is a number that is designated following the input of the “*” key after a telephone number that designates a normal destination, and a plurality of incoming calls that are connected to a terminating device in ISDN (Integrated Services Digital Network). It is used as a number that identifies the device. In a line with a telephone number of “06-6600-0000”, when a sub-address “01”, “02”, “03” is assigned to a device such as a telephone, FAX, or modem connected to the terminating device, If the user dials "06-6600-0000 * 02" from the device, the FAX device can receive a call. In the present invention, the control target terminal 41 (41a, 41b, 41c...) In the internal network 30 connected to the gateway device 11 is designated by the sub address, and the command and setting to be instructed to the control target terminal 41 respectively. The value is transmitted from the control execution terminal 37 of the external network 31.

  The gateway device 11 includes the following functional units and database as shown in FIG. 1 as software or hardware for designating and controlling the subordinate control target terminal 41 in accordance with the instruction given by the subaddress.

  First, an example of the accommodation device database 24 is shown in FIG. The “registration number” is, for example, a number designated as the first digit from the top of the subaddress, and the control target terminal 41 that is the control target is individually assigned. When defining with one digit of the sub-address, it can be defined for up to 10 terminals. When collectively controlling more terminals, two or more digits are assigned to terminal identification. Which registration number is assigned to which accommodation device as the control target terminal 41 may be designated by the user via the Web-GUI 25 described later, or the control target terminal 41 existing in the internal network 30 is scanned. It may be possible to execute an automatic registration means for automatically registering the type, name, and address of the accommodated device.

  Among the items of the accommodation device database 24, “accommodation device type” is a classification of products such as an air conditioner and a refrigerator, and “accommodation device name” indicates a model number. When there are a plurality of control target terminals 41 of the same classification, such as when there are a plurality of air conditioners, a different registration number is assigned to each. In that case, for example, in order to make it possible to determine which room the air conditioner will be in, the user may separately assign a unique name to each control target terminal 41 in the database. Next, the “accommodating device name” is a manufacturer name, a model number, or the like, and is desirably recorded so that the format of a control command to be finally transmitted can be identified. For example, even if the power is turned on and off, the format of the code that is actually transmitted differs depending on the manufacturer and type of the control target terminal 41, and the terminal control bundle 17 to be described later has to send a command statement suitable for each. It is.

  Among the items of the accommodation device database 24, the “accommodation device IP address” may be fixed, or may be assigned by the gateway device 11 itself by the DHCP server function of the gateway device 11. Good. By passing this IP address to the terminal control bundle 17 as the final destination of the control signal indicated by the sub-address, the command reaches each control target terminal 41. The “accommodating device MAC address” is automatically recognized by the gateway device 11 through communication within the internal network 30. In the case of the gateway device 11 having the DHCP server function, the assigned IP address is registered in the accommodated device database 24 after recognizing the MAC address in the same manner as a normal home router. At this time, if each control target terminal 41 can respond with its model number, manufacturer name, etc. in response to a request from each external interface, the data is automatically “accommodated device name” “accommodated device type”. It is particularly easy to use when the accommodation device automatic recognition means input in the item "is executed.

  Next, an example of the control signal database 23 is shown in FIG. “No.” is, for example, a number designated as the second digit from the top of the subaddress, and specific control contents are individually designated. When defining with one digit of the sub-address, a maximum of 10 types of instructions can be defined. However, it is desirable not to use 0 because of the relationship with a service using a general subaddress. In the example of the figure, 1 to 9 can be assigned, and 9 is in an undefined state. “Control content” indicates specific processing, and is to be transmitted as an instruction to the terminal control bundle 17 and an explanatory text to be displayed and played back to the user by the Web-GUI 25 or voice guidance. However, FIG. 3 shows only an interpersonal text sentence as an example. The command sentence may be a machine language, may be defined in a high-level language, or may be a grammar defined uniquely for the terminal control bundle 17.

  In addition, the specified value of the control content may be defined following the digit where “No.” is defined. For example, in “No. 3” in FIG. 3, it is possible to accept a numerical value indicating the passage of time transmitted in “minute” after the third digit from the top. “No. 5” accepts the air temperature and water heater set temperature sent in “Celsius” after the third digit from the top, or sets the channel, recording start time and recording end time to around 10 digits in the reservation of the recorder For example, accepting a numerical value sent. Note that the decimal point cannot be used, so it must be a numeric value that can be specified as an integer.

  In the above example, the control content defined in the control signal database 23 is made common to all the control target terminals 41, thereby eliminating the operation complexity.

  Furthermore, the gateway device 11 has a Web-GUI 25 that can be set for at least one of the databases 23 and 24. This Web-GUI is a database (a database that is received by sending data to a web browser of a terminal such as a personal computer installed on the internal network 30 side, accepts data sent by a form or the like via the web page, and so on. 23, 24,...) Can be changed. Specifically, the setting is changed for data reading means for reading the setting values of the respective databases 23 and 24 and a terminal such as a personal computer installed on the internal network 30 side (which may overlap with the control target terminal 41). Web server means for transmitting a page for use and data update means for writing data transmitted from the terminal into the databases 23 and 24 can be executed.

  Although not shown in the figure, when the accommodated device database 24 is constructed, there is a means for scanning devices connected only within the internal network 30 and automatically registering device names, device types, and the like. Good. In this case, the device side is preliminarily provided with data for supporting the present invention and set so as to be able to respond to the scan, or by bundle delivery or other methods from the external network 31. For example, there is a method in which data about individual devices can be acquired and updated, and device names can be identified by referring to scan results and updated data.

  Furthermore, it is preferable that the gateway device 11 has a password database 26 in which a numeric string that is a password is recorded in the case of designation by an external sub-address. If a digit string that is a password is accurately included between a predetermined digit and a predetermined digit as a sub-address, digits other than the password digit string are accepted as a control signal, otherwise control is performed. If the reception of the signal can be rejected, it is possible to suppress a risk that the control target terminal 41 is controlled without permission by a third party who knows the telephone number. This processing is preferably performed as part of the flow when the SIP function unit 21 described later receives a sub-address. It should be noted that password registration in the password database 26 may be performed via the Web-GUI 25 described above.

  When using the above password, the user using the control execution terminal 37 applies the number string corresponding to the password from the predetermined digit to the predetermined digit together with the designation of the control target terminal 41 and the control content. Then, input is made from the key of the control execution terminal 37.

  The SIP function unit 21 includes a terminal having a telephone function that can be a control execution terminal 37 of the external network 31 according to a SIP server (not shown) installed in the external network 31 according to a SIP (Session Initiation Protocol) protocol. Enable two-way real-time communication. In the present invention, the SIP function unit 21 executes subaddress extracting means for determining whether or not a subaddress is included in the INVITE message when an incoming call is received. In addition, if the sub-address is included in the above determination, the SIP function unit 21 executes a sub-address delivery unit that passes the sub-address as a control signal to the accommodation device control unit 22.

  Further, when the gateway apparatus 11 has the password database 26 and the password character string is set and registered, the SIP function unit 21 performs the following processing when receiving an incoming call, for example. First, among the sub-addresses included in the incoming call transmitted from the control execution terminal 37, the predetermined digits to the predetermined digits are recognized as the password input, and the subsequent digit string is recognized as the control signal. Execute password identification means. Here, from the predetermined digit to the predetermined digit, for example, the first digit to the eighth digit from the upper order are a digit string as a password, and the ninth and subsequent digits are recognized as a control signal. In this case, the ninth digit is the designated number of the control target terminal 41, the tenth digit is the instruction content, and the eleventh digit and later are designated values. Next, password confirmation means for comparing the recognized password with the password registered in the password database 26 is executed. If the comparison result does not match, the digit string recognized as the control signal is ignored or discarded, and not accepted as a control signal. Execute means.

  Furthermore, the gateway device 11 can confirm the input result and the control result by voice to the control execution terminal 37 as a part of the SIP function unit 21 or another function unit regardless of the presence or absence of the password. It is preferable to use a voice response means for replying. The user confirms the instructed contents by replying with voice in a call with the control execution terminal 37 what kind of control contents are accepted for which control target terminal by synthesized voice or recorded voice. If it is wrong, the situation can be corrected by transmitting the control signal again by the same procedure.

  The accommodation device control unit 22 calls the address of the control target terminal 41 designated with reference to the accommodation device database 24 as a destination address according to the control signal delivered from the SIP function unit 21, and the control signal database The control target specifying means for calling the code statement of the control content to the control target terminal 41 designated with reference to is executed. Then, a bundle instruction means for passing the called destination address and the control content code statement to the terminal control bundle 17 via the JNI 16 is executed. In addition, a specified value is added to the code sentence as necessary. For example, a content such as “change the set temperature of the air conditioner that is the destination 192.168.1.10. The specified temperature is 28 ° C.” is transmitted so that the bundle can be recognized.

  Of the above functional units, at least the SIP functional unit 21 is desirably implemented as the Native function 13. On the other hand, the accommodation device control unit 22 and the database group may be implemented as the Native function 13 or may be implemented on the OSGi framework 15.

  The terminal control bundle 17 executes command transmission means for transmitting a control command that specifically commands the above control content to the destination address of each control target terminal 41 as a standardized signal. The command statement of the control command may include a specified value. The format of the command statement and the grammar for each maker or terminal may be updated as appropriate by updating the bundle from the bundle distribution server 39.

  Next, a sequence for carrying out the present invention will be described with an example of FIG. First, a call including the telephone number and subaddress of the control destination is placed from the control execution terminal 37 to the SIP server 38 provided in the operator network 32 (S11). The type of the control execution terminal 37 is not particularly limited. In accordance with the SIP protocol, the SIP server 38 transmits the subaddress “21” as the “isub” parameter together with the telephone number to the destination gateway apparatus 11 specified by the telephone number (S12). If a password is included, this sub-address becomes longer. The gateway device 11 receives this call at the SIP function unit 21, and returns "180 Ringing" to the SIP server 38 (S13). In response to this, the SIP server 38 returns a signal that allows the control execution terminal 37 to hear the ringing tone (S14).

  If the gateway apparatus 11 has a password set in the password database 26 and the call includes a password, the password identification means for extracting the password after S12 is compared with the password database 26 for comparison. The password confirmation means is executed. If the comparison results in a coincidence and authentication, the process proceeds as described above. If the authentication is not successful, the authentication rejection means for returning “BYE” to the SIP server 38 is executed.

  Processing of the SIP function unit 21 when a call is accepted will be described with reference to the flow of FIG. 5 (S111). When an incoming call is received from the SIP server 38 of the operator network 32 as in S12 above (S112), the SIP function unit 21 adds an isub parameter to the P-Called-Party-ID in a series of signals accompanying INVITE. It is determined whether or not (S113). The format is not limited to this, and the subaddress may be directly specified as “isub =” in the INVITE statement, and the format is not particularly limited as long as it is specified so that it can be recognized as a subaddress. In any format, if no subaddress is assigned (S113 → No), the process is not related to terminal control but is processed as a normal incoming call (S114). Specifically, a call is made by making an incoming call to a fixed telephone or a FAX machine connected to the gateway device 11 (S114). On the other hand, if the sub address is given, the parameter is read (here, “21”), the sub address extracting means for extracting is executed, and the sub address delivering means for notifying the accommodated device control unit 22 of the extracted sub address is executed. (S21, S115). Here, the processing temporarily moves to the accommodation device control unit 22 (S116).

  Next, an example of processing of the accommodation device control unit 22 that has received the control signal extracted from the sub-address in S21 and S115 will be described with reference to the flow of FIG. 6 (S121). The accommodated device control unit 22 that has received the control signal (S122 ~) refers to the accommodated device database 24 and the control signal database 23 (S22), and the device name and address of the control target terminal 41, and corresponding thereto A control command is obtained (S23), and the control target specifying means is executed.

  Specifically, first, the most significant digit (corresponding to “2” of “21”) of the control signal extracted from the sub address is read, and an inquiry is made to the accommodation device database 24 (S123). When there is no matched parameter in the accommodated device database 24 (S124 → No), a failure of setting is returned to the SIP function unit 21 as an instruction to the non-existing control target terminal 41 (S125, corresponding to the failure of S24 in FIG. 4) .) On the other hand, if there is a record that matches the corresponding parameter (S124 → Yes), the device information of the control target terminal 41 is recorded in the storage area managed by the accommodated device control unit 22 (S131). The device information includes an IP address and a model number for embodying a command statement.

  Next, the next digit of the most significant digit of the control signal extracted from the subaddress (here, corresponding to “1” of “21”) is read, and an inquiry is made to the control signal database 23 (S132). When there is no matched parameter in the control signal database 23 (S133 → No), a setting failure is returned to the SIP function unit 21 as an instruction to execute an undefined command (S125, similarly, when S24 in FIG. 4 fails). Equivalent.) On the other hand, if there is a record that matches the corresponding parameter (S133 → Yes), the control content information recorded as the record is recorded in the storage area managed by the accommodation device control unit 22 (S134). This control content is a command statement or data according to a protocol that can be recognized by the terminal control bundle 17 regarding power ON / OFF, change of a set value, and the like.

  When the device information and the control content can be confirmed as described above and stored in the storage area, the accommodation device control unit 22 sends the address and the control content to the terminal control bundle 17 on the OSGi framework 15 via the JNI 16. The bundle instruction means for transmitting the above is executed (S31, S135). Here, it is desirable that the format for transmitting to the terminal control bundle 17 is standardized as much as possible for basic operations that can be shared. However, it is often the case that control is difficult to standardize for each manufacturer or product. In this case, the unique control content is transmitted as an optional property, and the terminal control bundle 17 can interpret the optional property.

  On the other hand, the accommodation device control unit 22 executes control content notification means for notifying the SIP function unit 21 that the control is performed on the device name (S24, S136). “21” shown in the example is a format that can be recognized by the SIP function unit 21 with the content of “<Power ON of Air Conditioner>”. Thus, the flow of the accommodated device control unit 22 ends (S137).

  The SIP function unit 21 notified of the device name and the control content returns a “200 OK” according to the SIP protocol to the SIP server 38 (S25), and establishes a call using the SIP protocol. After that, the voice reply means for confirming by voice is executed to the control execution terminal 37 which is the transmission source (S26). Specifically, it returns a voice message such as “Do you want to turn on the air conditioner?”.

  The terminal control bundle 17 that has received the address and the control content executes the command transmission means for transmitting a control command to the control target terminal 41 specified by the address on the internal network 30 side (S32). If the control content is standardized, the terminal control bundle 17 converts it into a control command as a basic function and transmits it. If the property is an option as described above, the terminal control bundle 17 can refer to a command sentence adapted to each original specification as a database that can be referred to. This database is transmitted from the bundle distribution server 39 or a server capable of transmitting in parallel therewith. The control target terminal 41 that has received the control command executes power supply ON / OFF and change of the set value according to the standardized command statement, and executes the command from the control execution terminal 37.

  In parallel with the terminal control bundle 17 issuing a control command, the SIP function unit 21 notifies the SIP server 38 of “BYE” according to the SIP protocol (S41), and calls between the control execution terminal 37 and the control execution terminal 37. Is disconnected, and a series of processing ends (S42).

  The series of operations described above may be executed by directly pressing a telephone number. However, when the control execution terminal 37 is a multi-function device such as a smartphone, an instruction by a sub-address using the telephone number and a control target terminal 41 to be designated are displayed. The above-described call (S11) process may be simplified by an application that can be referred to as a comparison table. Although this is linked with the contents of the control content database and the accommodated device database 24, it is not necessarily differentiated for each manufacturer or product, so that it is not necessary for the user to memorize the manufacturer-specific events and can be used for general purposes. .
