Description

  The present invention relates to an information processing system capable of setting device information of electronic devices and operating devices from the outside.

  Conventional information processing systems capable of setting device information and operating devices from the outside normally perform the following operations. That is, for example, when making a recording reservation for a home video from an external device such as a portable terminal, the external device holds information for communicating with the video, and the external device is based on the information. The video recording was accessed and the recording reservation information entered by the user was transmitted.

  However, in the above-described conventional technology, for example, when a video is new and information for communicating with the video is changed, it must be set in an external device such as a portable terminal. For security reasons, it is not preferable that the home video can be easily accessed from the outside.

  For example, when communicating with video by TCP / IP from an external device, the IP address, which is information for communicating with video, is not always fixed, but dynamically according to protocols such as PPP and DHCP. The IP address is dynamically changed due to various factors such as server operation from the ISP and temporary communication interruption. Further, even when the IP address is known, the port number further necessary for communicating with the video may be dynamically changed by the Internet address conversion function installed in the ADSL router. Such a conversion function is popularly called a NAPT (Network Address and Port Translation), IP, or masquerading function.

  Therefore, in order to access such a device having a dynamically changing IP address and port from the outside (for example, outside the home), it is necessary to know the current IP address and port by some method. Conventional technologies for such applications include a Dynamic DNS server. The Dynamic DNS server notifies the client terminal of the current IP address of the device using the DNS protocol defined by RFC which is an Internet standard, thereby enabling access from the client terminal to the device in the home. . However, since the DNS protocol is a method for notifying an IP address, it cannot notify the current port number. In addition, because the DynamicDNS server has a cache mechanism in which the nearest server answers the address, when handling the address of a dynamically changing device, old information may be cached and an incorrect address is notified. There was.

In order to solve the above problems, the present invention provides an electronic device connected to a communication control device that manages a port for connecting to the Internet;
An access device including an access device identifier storage unit that stores an access device identifier that is information for identifying itself, an access device identifier that is information for identifying the access device, and a dynamic access to the electronic device A server constituting an information processing system that is an Internet system composed of a server device provided with an access information management unit that manages information associated with a global IP address that changes and information indicating a port position in the communication control device A device,

A transmission instruction receiving unit for receiving the transmission command information for controlling the electronic apparatus having the access device identifier from the previous SL access device server device identifier is registered identifying the server device,
Using the access device identifier of the transmission command received by the transmission command reception unit as a key, the transmission is performed from information including information indicating a global IP address and a port position regarding an electronic device paired with a previously stored access device identifier . An electronic device access information transmitting unit that retrieves electronic device access information corresponding to an access device identifier included in the instruction and transmits the electronic device access information to the access device;
A server device is provided. Such a server device can easily set and operate the device information of the electronic device from the outside without any security problem, and can reliably cope with an IP address and port number that can be dynamically changed.

  According to the present invention, it is possible to easily access a specific electronic device from the outside while ensuring security.

  Embodiments of the present invention will be described below in detail with reference to the drawings. Note that in this embodiment, components using the same reference numerals and steps in the flowcharts perform the same function, and thus description of what has been described once may be omitted.

  FIG. 1 is a system configuration diagram of an information processing system according to the present embodiment. The information processing system includes an electronic device 11, a router 12, a server device 13, and an access device 14. FIG. 2 is a block diagram of the information processing system according to the present embodiment. The electronic device 11 includes an operation screen information storage unit 1101, an operation screen information transmission unit 1102, a device operation information reception unit 1103, a device operation information setting unit 1104, and a device operation unit 1105. The router 12 functions to connect the electronic device 11 to the Internet, and has a route control function, a network address translation function (NAT), and the like. The server device 13 includes an access information management unit 1301, a transmission command reception unit 1302, and an electronic device access information transmission unit 1303. The access device 14 includes an access device identifier storage unit 1401, a server device identifier storage unit 1402, an access request reception unit 1403, a transmission command transmission unit 1404, an electronic device access information reception unit 1405, an electronic device access information display unit 1406, and operation screen information. A transmission command reception unit 1407, an operation screen information reception unit 1408, an operation screen display unit 1409, a device operation information reception unit 1410, and a device operation information transmission unit 1411 are included.

  The operation screen information storage unit 1101 stores operation screen information that is information constituting a screen for operating the electronic device 11 or another electronic device. The operation screen information is information constituting a user interface (such as a menu or a panel) for making a recording reservation for the video when the electronic device to be operated is a video, for example. This information is described in, for example, C-HTML (Compact HMT) or HTML. For example, when the electronic device to be operated is a computer and the user wants to call up an image album in the computer, the operation information is information constituting a menu screen or panel for displaying or searching for the image album. This information is described in, for example, C-HTML or HTML. The operation screen information storage unit 1101 is preferably realized by a nonvolatile recording medium, but may be realized by a volatile recording medium.

In response to a request from the access device 14, the operation screen information transmission unit 1102 acquires the operation screen information stored in the operation screen information storage unit 1101 and transmits it to the access device 14 via the router 12. Acquiring operation screen information in response to a request from the access device 14 usually means selecting one operation screen information from two or more operation screen information. However, it is needless to say that selection is not necessary when there is only one operation screen information. The operation screen information transmission unit 1102 can be usually realized by a wireless or wired communication means (for example, a network card and its driver software), but may be realized by a broadcasting means.

  The device operation information receiving unit 1103 receives device operation information from the access device 14 via the router 12. The device operation information receiving unit 1103 can usually be realized by wireless or wired communication means (for example, a modem and its driver software), but can also be realized by means of receiving a broadcast (for example, a tuner and its driver software). It is. When the device operation information receiving unit 1103 is realized by a communication unit, the device operation information receiving unit 1103 and the operation screen information transmitting unit 1102 are usually realized by one physically unit.

  The device operation information setting unit 1104 stores the device operation information received by the device operation information receiving unit 1103. Accumulation usually refers to storage in a non-volatile recording medium, but may be temporary storage in a volatile recording medium. The recording medium may be a recording medium built in the electronic device or an external recording medium. Further, the device operation information may be used when the electronic device 11 performs some operation, or is read (or received) by another electronic device connected to the electronic device 11 and used. May be. When the electronic device 11 is a so-called home server in the home and other electronic devices can be connected to the home server, such as a video or a computer, the other electronic devices connected to the electronic device 11 use the device information. An embodiment is conceivable. The device operation information setting unit 1104 is normally realized by software, but may be realized by hardware.

  The device operation unit 1105 performs an operation based on the device operation information received by the device operation information reception unit 1103. The device operation unit 1105 operates based on the device operation information when the device operation information setting unit 1104 stores the device operation information. This operation differs depending on the device operation information. When the device operation information is information for making a video recording reservation, the operation is recording.

The access information management unit 1301 stores one or more records having an access device identifier that is information for identifying the access device 14 and electronic device address information that is information for accessing the electronic device 11. A table having one or more records is called an access information management table. The access device identifier is, for example, a mobile phone number when the access device 14 is a mobile phone. The access device identifier is, for example, a global IP address when the access device 14 is a computer connected to the Internet. The access device identifier may be a user identifier that identifies a user who holds the access device, for example. The user identifier is a so-called login identifier and password. The user identifier is, for example, information input by the user using the input unit of the access device. The electronic device address information is, for example, a global IP address for communicating with the electronic device 11. This global IP address is, for example, a global IP address assigned to the router 12. However, when the electronic device 11 is directly connected to the Internet without the router 12, the electronic device address information is, for example, a global IP address assigned to the electronic device 11. The electronic device address information is, for example, a set of a global IP address and a port number. The electronic device address information is updated to the latest address information by the electronic device 11 appropriately registering with the server device. The access information management unit 1301 is preferably realized by a nonvolatile recording medium, but may be realized by a volatile recording medium.

  The transmission command receiving unit 1302 receives a transmission command having an access device identifier from the access device 14. The transmission command is a command that prompts transmission of electronic device access information that is information for accessing the electronic device 11. The transmission command receiving unit 1302 is usually realized by wireless or wired communication means (for example, a modem and its driver software, a network card and its driver software, etc.), but can also be realized by means of receiving a broadcast.

  The electronic device access information transmitting unit 1303 obtains electronic device address information that is paired with the access device identifier included in the transmission command received by the transmission command receiving unit 1302 from the access information management unit 1301, and the electronic device access information having the electronic device address information is acquired. The device access information is configured, and the electronic device access information is transmitted to the access device 14. Note that the electronic device access information may consist only of electronic device address information. In such a case, the electronic device access information transmission unit 1303 does not perform an operation of configuring the electronic device access information. The electronic device access information transmission unit 1303 is usually realized by a wireless or wired communication means (for example, a network card and its driver software), but can also be realized by a broadcasting means. When the electronic device access information transmission unit 1303 is realized by a communication unit, the electronic device access information transmission unit 1303 and the transmission command reception unit 1302 are usually realized by a single physical means.

  The access device identifier storage unit 1401 stores an access device identifier that identifies the access device 14. The access device identifier storage unit 1401 is preferably realized by a nonvolatile recording medium, but may be realized by a volatile recording medium. When the access device identifier is information input by the user (for example, a login identifier and a password), the access device identifier storage unit 1401 is preferably a non-volatile recording medium.

  The server device identifier storage unit 1402 stores a server device identifier that is information for identifying the server device 13. The server device identifier storage unit 1402 is preferably realized by a non-volatile recording medium, but may be realized by a volatile recording medium.

  The access request receiving unit 1403 receives an access request to the server device 13. For example, the access request receiving unit 1403 receives an access request to the server device 13 from a user of the access device 14. When the access device 14 is a mobile phone, the access request is usually an input from a numeric keypad. When the access device 14 is a computer, the access request is an input from a keyboard or mouse. Accordingly, the access request receiving unit 1403 is software that drives keys, or driver software such as a keyboard. However, the access request receiving unit 1403 may receive a command indicating access to the server device 13 from another device.

  When the access request reception unit 1403 receives an access request, the transmission command transmission unit 1404 accesses the electronic device 11 to the server device identified by the server device identifier stored in the server device identifier storage unit 1402. A transmission command, which is a command for prompting transmission of electronic device access information, which is information on the device, is transmitted. The transmission command has an access device identifier. The transmission command transmission unit 1404 is normally realized by a wireless or wired communication means (for example, a network card and its driver software), but can also be realized by a broadcasting means.

  The electronic device access information receiving unit 1405 receives the electronic device access information transmitted from the server device 13 in response to the transmission of the transmission command. The electronic device access information receiving unit 1405 is usually realized by a wireless or wired communication means (for example, a network card and its driver software), but can also be realized by a means for receiving a broadcast.

  The electronic device access information display unit 1406 displays part or all of the electronic device access information received by the electronic device access information reception unit 1405. The electronic device access information display unit 1406 can be realized by, for example, a display and software for controlling display of data.

  The operation screen information transmission command reception unit 1407 receives an input for the electronic device access information displayed by the electronic device access information display unit 1406. The operation screen information transmission command receiving unit 1407 is normally realized by the same means as the access request receiving unit 1403.

  When the operation screen information transmission command receiving unit 1407 receives an input, the operation screen information receiving unit 1408 urges the electronic device 11 to transmit the operation screen information based on the input, and receives the operation screen information. The operation screen information receiving unit 1408 is usually realized by a wireless or wired communication means (for example, a network card and its driver software), but can also be realized by a broadcast means and a means for receiving a broadcast.

  The operation screen display unit 1409 displays an operation screen based on the operation screen information received by the operation screen information reception unit 1408. The operation screen information display unit 1409 can be realized by, for example, software that displays and controls display and data.

  The device operation information receiving unit 1410 receives device operation information input based on the operation screen displayed on the operation screen information display unit 1409. The device operation information receiving unit 1410 normally receives an input from the user of the access device 14. The input of the device operation information may be a menu selection or may be data input using a keyboard or the like. The device operation information receiving unit 1410 is usually realized by the same means as the access request receiving unit 1403 and the operation screen information transmission command receiving unit 1407.

  The device operation information transmission unit 1411 transmits the device operation information received by the device operation information reception unit 1410 to the electronic device 11. The device operation information transmitted by the device operation information transmitting unit 1411 is not necessarily the same as the device information received by the device operation information receiving unit 1410. The data formats of both may be different. The device operation information transmission unit 1411 is usually realized by a wireless or wired communication means (for example, a network card and its driver software), but can also be realized by a broadcasting means. When the device operation information transmission unit 1411 is realized by a communication means, the device operation information transmission unit 1411, the transmission command transmission unit 1404, the electronic device access information reception unit 1405, and the operation screen information reception unit 1408 are usually one physical unit. Realized by means.

Hereinafter, the operation of the information processing system will be described. First, the operation of the electronic device 11 will be described using the flowchart of FIG.
(Step S301) The operation screen information transmission unit 1102 determines whether or not there is a request for transmitting operation screen information from the access device 14. If there is a request, the process goes to step S302, and if there is no request, the process returns to step S301.

  (Step S302) The operation screen information transmission unit 1102 acquires operation screen information from the operation screen information storage unit 1101.

  (Step S303) The operation screen information transmission unit 1102 transmits the operation screen information acquired in step S302.

(Step S <b> 304) The device operation information receiving unit 1103 determines whether device operation information has been received from the access device 14. If device operation information is received, go to step S305,
If no device operation information is received, the process returns to step S304.

  (Step S305) The device operation information setting unit 1104 stores the device operation information received in step S304. Various uses of the stored device operation information are conceivable. In some cases, the electronic device 11 operates using the device operation information accumulated. In addition, a device connected to the electronic device 11 via a network may operate using device operation information. Furthermore, the device operation information setting unit 1104 may temporarily store device operation information in a memory and perform an operation immediately based on the device operation information. In some cases, the device operation information setting unit 1104 does not function, and the device operation information receiving unit 1103 performs an operation immediately based on the device operation information received. These operations are performed by the device operation unit 1105.

Next, operation | movement of the server apparatus 13 is demonstrated using the flowchart of FIG.
(Step S401) The transmission command receiving unit 1302 determines whether a transmission command having an access device identifier has been received from the access device 14. If a transmission command is received, it will go to step S402, and if a transmission command is not received, it will return to step S401.

  (Step S402) The electronic device access information transmission unit 1303 extracts the access device identifier from the transmission command received in step S401.

  (Step S403) The electronic device access information transmission unit 1303 searches the access information management unit 1301 using the access device identifier as a key. If the electronic device address information corresponding to the access device identifier is acquired as a result of the search, the process goes to step S404, and if the electronic device address information cannot be acquired, the process jumps to step S405.

  (Step S404) The electronic device access information transmitting unit 1303 configures electronic device access information including the electronic device address information acquired in step S403. Note that the electronic device access information and the electronic device address information may be the same information. In such a case, this step does nothing. That is, this step is nop.

  (Step S405) The electronic device access information transmission unit 1303 configures electronic device access information including an error message. This error message is a message indicating that there is no electronic device 11 accessible from the access device 14.

  (Step S406) The electronic device access information transmitting unit 1303 transmits the electronic device access information configured in step S404 or step S405 to the access device 14.

Next, the operation of the access device 14 will be described using the flowchart of FIG.
(Step S501) The access request reception unit 1403 determines whether an access request to the server device 13 has been received. If an access request is accepted, the process goes to step S502, and if no access request is accepted, the process returns to step S501.

  (Step S502) The transmission command transmission unit 1404 acquires an access device identifier from the access device identifier storage unit 1401.

  (Step S503) The transmission command transmission unit 1404 acquires the server device identifier from the server device identifier storage unit 1402.

(Step S504) The transmission command transmission unit 1404 configures a transmission command using the access device identifier acquired in step S502. If the transmission command consists only of the access device identifier, nothing is done in step S504. That is, step S504 is nop.

  (Step S505) The transmission command transmission unit 1404 transmits the transmission command configured in step S504 to the server device 13 identified by the server device identifier acquired in step S503.

  (Step S506) The electronic device access information receiving unit 1405 determines whether or not electronic device access information has been received. If the electronic device access information is received, the process proceeds to step S507. If the electronic device access information is not received, the process returns to step S506.

  (Step S507) The electronic device access information display unit 1406 configures information (for example, menu information) to be displayed using the electronic device access information received in step S506.

  (Step S508) The electronic device access information display unit 1406 displays the information configured in step S507. As a result, for example, an operation menu is displayed on the display.

  (Step S509) The operation screen information transmission command reception unit 1407 determines whether an appropriate input for the information displayed in step S508 has been received. If an input is accepted, the process goes to step S510, and if no input is accepted, the process returns to step S509.

  (Step S510) The operation screen information receiving unit 1408 prompts the electronic device 11 to transmit the operation screen information. “Prompt transmission” usually means transmitting a command to instruct to transmit operation screen information. However, the transmission of the operation screen information may be prompted by other means.

  (Step S511) The operation screen information receiving unit 1408 determines whether or not operation screen information has been received. If the operation screen information is received, the process goes to step S512. If the operation screen information is not received, the process returns to step S511.

  (Step S512) The operation screen display unit 1409 configures information to be displayed from the operation screen information received in step S511. This information is, for example, menu information that prompts a user operation.

  (Step S513) The operation screen display unit 1409 displays the information configured in step S512.

  (Step S514) The device operation information receiving unit 1410 receives the device operation information input based on the information displayed in step S513. The input of the device operation information may be simply a menu item selection. Also, the input of the device operation information may be input of setting information (time, recording reservation information, etc.) for the device using a keyboard or the like.

  (Step S515) The device operation information transmitting unit 1411 configures device operation information to be transmitted from the input received in step S514.

  (Step S516) The device operation information transmission unit 1411 transmits the device operation information configured in step S515.

Note that steps S507 to S509 are not essential in the flowchart of FIG. That is, it is not necessary to display all or part of the electronic device address information on the access device 14 and prompt the transmission of the operation screen information based on the user instruction. For example, by sending a URL whose electronic device address information includes the IP address of the electronic device 11 to the access device 14 and automatically jumping to a page (data described in HTML) indicated by the URL after a predetermined time, the user 's You may move to the next step (operation that prompts the electronic device to transmit operation screen information) without an instruction.

Hereinafter, a specific operation of the information processing system in the present embodiment will be described. A system configuration diagram of a specific information processing system is shown in FIG. The information processing system includes an electronic device 11, a router 12, a server device 13, an access device 14, a video 61, and a personal computer 62. The electronic device 11 is a server device (so-called home server) in the home. Then, the home server 11, Ru communicable der the device connected to the Internet via a router 12. Also, the server device 13, the service providers connected to the Internet (hereinafter, appropriately referred to as "ISP".) Which is an information processing apparatus. Further, the access device 14 is a mobile phone that can be moved. In this information processing system, the home server 11 can be accessed from the mobile phone 14 while ensuring the security of the home server 11. The specific operation and data example will be described below.

  Now, the server device 13 holds an access information management table as shown in FIG. The access information management table stores one or more records having “page name”, “global IP address”, “electronic device name”, “password”, and “mobile phone number”. However, the access information management table may be a non-normal table or a normal table as shown in FIG. The “page name” is the name of a page in a unit displayed on the mobile phone 14. When a page is displayed on the mobile phone 14, the “page name” is displayed on the screen of the mobile phone 14. . The “global IP address” is information for communicating with the electronic device 11. In place of the “global IP address”, communication with the electronic device 11 may be performed using a combination of a “global IP address” and a “port number”. The “electronic device name” is a name that identifies the electronic device 11 and is a name that can be understood by the user. The “password” is a number that should be input when establishing communication connection with the electronic device 11 that can communicate with the “global IP address”. The “mobile phone number” is a phone number that identifies the mobile phone 14.

  The home server stores menu and panel information shown in FIG. FIG. 8 shows menus and panels for accessing and operating the video 61 and personal computer 62 connected to the home server 11 from the mobile phone 14. The menus and panels in FIG. 8 have a hierarchical structure. Specifically, the top panel has two operation menu items (“recording reservation” and “image album”) and an end button. If the “recording reservation” menu item is selected, the process proceeds to the “recording reservation panel” in FIG. This “recording reservation panel” is a panel for setting a recording reservation for the video 61. When “ch” (channel), “start time” and “end time” are input in this “recording reservation panel” and the enter button is pressed, the data is set in the home server 11 and the video 61 schedules recording. To do. If the “Image Album” menu item is selected, the process moves to the “Image Album Menu” in FIG. Then, “read” or “register” can be selected. When “read” is selected, the selected photograph (image) is read from the personal computer 62 and displayed on the mobile phone 14. If “Register” is selected, a photo can be registered in the personal computer 62 from the mobile phone 14 via the home server 11. If the end button is pressed, the menu display is ended. As described above, when the menu item “image album” is selected, the device immediately operates based on the device operation information received by the device operation information receiving unit of the electronic device (home server). In other words, when the device immediately operates, it means that a photo is called or registered.

Hereinafter, the flow of the above operation will be described in detail. A specific operation of the information processing system will be described with reference to FIG. First, the user of the mobile phone 14 inputs an access request to the server device 13. This access request is made by registering a server device identifier (URL for accessing the server device 13) as a bookmark and selecting the bookmark ((1) in FIG. 9). Next, the cellular phone 14 transmits a transmission command including its own telephone number “090-1111-2222” to the server device 13 and goes to the connection ((2) in FIG. 9). Next, the server device 13 searches the management table of FIG. 7 using the telephone number “090-1111-2222” as a key, and the electronic device having “page name” “global IP address” “electronic device name ” “password”. Device access information ("Yamada-kun" page) is transmitted to the mobile phone 14 ((3) in FIG. 9). At that time, it is assumed that advertisement information (not shown) stored in the server device 13 is also transmitted. Then, the mobile phone 14 receives the electronic device access information and displays a part or all of the electronic device access information. At that time, the mobile phone 14 also displays the received advertisement information. Then, the user selects the electronic device 11 to be accessed ((4) in FIG. 9). In FIG. 9, there is only one electronic device that can be accessed, but it is needless to say that there may be a plurality of accessible electronic devices. Although not shown in FIG. 9, the selection of (4) in FIG. 9 can be made by entering the password “0123”.

  Next, since the home server is selected, the mobile phone 14 connects to the router 12 identified by the global IP address “123.222.0.1” ((5) in FIG. 9), and the NAT of the router 12 is connected. The home server 11 in the home is accessed with the (static FW) function ((6) in FIG. 9). Next, the home server 11 transmits the stored operation screen information via the router 12 ((7) in FIG. 9). The mobile phone 14 receives the operation screen information and displays an operation menu. Then, the user selects “(1) recording reservation” ((8) in FIG. 9). Next, the mobile phone 14 transmits information indicating that “(1) recording reservation” has been selected to the home server 11 via the router 12 ((9) in FIG. 9). Next, the home server 11 transmits the next operation screen information via the router 12 ((10) in FIG. 9). The next operation screen information is information constituting the recording reservation panel of FIG. Next, the mobile phone 14 receives and displays the next operation screen information. Then, the user inputs recording reservation information (“ch”, “start time”, “end time”, etc.) ((11) in FIG. 9). When the user presses (selects) the enter button, device operation information (for example, “ch = 8”, “start time = 19: 00”, “end time = 21: 00”) is sent via the router 12 to the home server 11. ((12) in FIG. 9). Next, the home server 11 accumulates device operation information (for example, “ch = 8”, “start time = 19: 00”, “end time = 21: 00”) ((13) in FIG. 9). Next, the video 61 obtains device information (for example, “ch = 8”, “start time = 19: 00”, “end time = 21: 00”) from the home server 11 and sets it. The video 61 is recorded as instructed ((14) in FIG. 9).

  As described above, according to the present embodiment, it is possible to easily access a specific electronic device from the outside while ensuring security. The specific electronic device is, for example, an electronic device such as a home computer, a video, or a refrigerator.
