Description

  The present invention relates to a gateway device capable of extending a public wireless LAN service using a bundle on a Java virtual machine.

  The traffic of network services centering on the Internet has been increasing with the development of video distribution services and rich smartphone games. The fixed line is responding to the spread of the optical fiber network. On the other hand, as long as there is a restriction on the frequency range in the mobile line, there are many cases where the amount of communication and the communication speed are restricted, and if there is no restriction, a huge communication fee is required. In order to counter this, not only mobile phone communication but also access points (APs) provided in various places are released, thereby reducing the load on the mobile phone and reducing the charge to the user. Has been done.

  For example, in Patent Document 1, the SSID information of a mobile AP connected to a mobile line is read by an indoor AP physically connected to the mobile AP, and the mobile terminal communicating with the mobile AP can connect to the Internet through the indoor AP. The technique to make is presented.

  As such APs, there are cases where a gateway device having a Wi-Fi function that leads to a fixed line such as an optical line that a user has contracted at home is used for own use, and public spaces such as coffee shops, stations, and convenience stores. In some cases, a large number of users share a gateway device having a Wi-Fi function that leads to a fixed line drawn by the user. Many current gateway devices have multi-SSID functions. For example, in the case of a home gateway device for home use, a guest who can connect to the Internet but cannot communicate with a wireless LAN based on the SSID separately from the SSID of the wireless LAN environment having the Internet connection environment that the owner normally uses. Products that can construct a wireless LAN in which an SSID is set are sold (for example, Non-Patent Document 1).

  On the other hand, a gateway device used for a so-called public wireless LAN service placed in a public space defines a plurality of SSIDs so as to be able to support a plurality of public wireless LAN services independently, and depends on each SSID. Those that can construct public wireless LANs are increasing. For example, when a mobile line operator constructs a public wireless LAN environment in order to reduce the amount of communication to his / her own mobile line, the gateway device having the above multi-SSID is developed by each mobile line operator. Wireless LAN is deployed with SSID corresponding to public wireless LAN service. When a user uses a dedicated public wireless LAN service provided by such a mobile line carrier or the like, access is automatically guided to a dedicated authentication page prepared by each carrier at the first connection. . Through authentication by SIM and password on this authentication page, the user not only provides the gateway device but also other gateway devices that provide a public wireless LAN provided by the same mobile network operator set up with the same SSID. A mechanism to make it available is being developed.

  On the other hand, in recent years, a communication device such as a home gateway (HGW) is also equipped 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, in Non-Patent Documents 2 and 3, Java is installed in the HGW installed in each home connected to a provider network (Next Generation Network: NGN) configured with IPv6 under the name FLET'S JOINT (registered trademark). 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.

  However, when a new public wireless LAN service is to be developed, it is necessary to previously embed necessary setting information such as commonly used SSID and authentication page address in the gateway device. For this reason, whenever such setting information is added or changed, a new gateway device must be developed or reconfigured, and a service is provided by newly deploying the corresponding gateway device. It took a period to do.

  For the same reason, even if an attempt is made to open an AP that leads to a fixed line set by the owner of a general home to a guest using a multi-SSID, the AP is operated with a common SSID with a public wireless LAN service operated by an existing service provider. If it tries to do so, the detailed setting which is optimal for that will have to be performed by each owner, and it was not possible to easily introduce it.

  On the other hand, the indoor AP described in Patent Document 1 only reads the information of the physically connected mobile AP and temporarily serves as a substitute for it, and it is assumed that a plurality of SSIDs are set together. It wasn't.

  Accordingly, an object of the present invention is to enable public wireless LAN services to be deployed by adding and changing settings such as SSID by remote control even after an AP is installed once. As a result, it is an object of the present invention to enable service providers who intend to provide public wireless LAN services to increase the number of APs that can easily provide public wireless LAN services later.

This invention
A gateway device having a Wi-Fi function,
An OSGi framework that can execute bundles installed on the Java Virtual Machine (JVM) and receive bundles from remote servers on an external network;
On the above OSGi framework,
When the SSID information management bundle having the setting information including the SSID used when the wireless LAN is constructed by executing the Wi-Fi function is received from the remote server, the setting information is extracted, and the gateway device itself Has an information delivery bundle that delivers information to the Native function unit
As the above Native function part,
A wireless function unit that actually executes the Wi-Fi function of the gateway device;
A configuration information function unit configured to receive the setting information from the information delivery bundle and set wireless LAN information transmitted by the wireless function unit according to the setting information.
The gateway device with Wi-Fi function has solved the above problems.

  Conventionally, the setting of the part that operates as the Native function part of the gateway device can be changed through the WEB-GUI etc. that the Native function part also has, and the above Config information function part was responsible for this change processing. is there. In addition, there is an information delivery bundle that delivers information from the OSGi framework (ie, JVM) to the Native function unit including the Config information function unit. By using this information delivery bundle, setting information for the Wi-Fi function is passed from the OSGi framework. That is, the bundle on the OSGi framework can be downloaded and installed from a remote server that can distribute the bundle on the external network. On the other hand, the setting information to be added or changed is input to the remote server as an SSID information management bundle so that the SSID information management bundle can be distributed to individual gateway devices.

  In the gateway device according to the present invention, when the information delivery bundle is received, the setting information is extracted from the SSID information management bundle, and then the Config information function unit in the Native function unit is extracted. To communicate. When the Config information function unit receives the setting information derived from the SSID information management bundle, the Config information function unit changes the setting according to the setting information to the wireless function unit. However, security is ensured by setting access right information so as not to accept information via other than the SSID information management bundle.

  Further, when the setting information received by the Config information function unit is the same SSID name as the already registered SSID name, the already set information can be rewritten.

  According to the present invention, for a gateway device having a Wi-Fi function connected to an external network, a wireless LAN based on setting information including a required SSID can be developed by changing the setting from a remote server. As a result, an implementer of the system according to the present invention can remotely communicate with a gateway device permitted to provide a service in accordance with a contract with a service provider that is a company or organization that intends to develop a public wireless LAN service. The setting information necessary for the operation can be transmitted to provide the public wireless LAN service with the setting including a predetermined SSID to the gateway device.

  Hereinafter, the present invention will be described in detail with reference to embodiments. The present invention is a system having a gateway device having a Wi-Fi function capable of constructing a wireless LAN environment and a function of connecting to the Internet, and a remote server communicating with the gateway device. The LAN service is developed.

  FIG. 1 shows the relationship between the functional block of the gateway device 11 and other servers and networks that communicate with it. The gateway device 11 divides the internal network 5 and the external network 6 and relays communication between them. The external network 6 basically communicates with the Internet 8 through a carrier network 7 managed by a communication carrier that provides the gateway device 11 and the remote server 35 and performs an Internet connection service. On the other hand, the internal network 5 may be a home LAN or an open LAN that is originally installed in a public space. As a part of the internal network 5, it is necessary to be able to deploy the wireless network 5a by the wireless antenna 17 controlled by the wireless function unit 25 described later. Moreover, you may have the internal network interface 18 connected with the wired network which comprises home LAN.

  The gateway device 11 includes an arithmetic device (not shown) and a storage unit (not shown), and has a native function unit 13 that is mounted on a NativeOS (not shown) and operates on an actual arithmetic device. . The basic functions are the same as those installed in a general home gateway (HGW) or the like, but constitutes the present invention together with additional elements to be described later. In addition, the gateway device 11 has a JVM (Java Virtual Machine) 14 which is a virtual machine. The JVM 14 has an OSGi framework 15 that can dynamically add software modules called bundles. When the JVM 14 cooperates with the Native function unit 13, data and instructions are mutually exchanged via a JNI (Java Native Interface) 16 which is a set of APIs (Application Programming Interfaces) for using one function from the other. To do.

  The Native function unit 13 includes a wireless function unit 25 that controls the wireless antenna 17 that deploys the wireless network 5 a in the internal network 5. In addition, it has a Config information function unit 26 that can perform settings of the wireless function unit 25, settings of the external network interface 19 that communicates with the external network 6, communication settings when relaying between them, and other settings. That is, the configuration of the wireless network 5a deployed by the wireless antenna 17 can be changed and determined through the Config information function unit 26. Settings such as the SSID of the wireless network 5a, the encryption method, the password, the radio wave intensity, and the URL of the page to be authenticated can be changed. In the case of a general gateway device, these changes are made via a Web-GUI provided for access from a terminal from the internal network 5 side.

  Further, it is preferable that the wireless function unit 25 and the wireless antenna 17 have a so-called multi-SSID function capable of developing a plurality of wireless networks 5a having different SSIDs in parallel. When the installer of the gateway device 11 is an individual of a general household, the wireless network 5a used by other users connected as a public wireless LAN service and the wireless network 5b for the individual to receive a connection service to the Internet 8 This is because a security problem will occur if these are not separated. In this case, the wireless network 5a deployed as a public wireless LAN service denies access to the Web-GUI for changing the setting of the gateway device 11, thereby ensuring the security of the individual.

  As the multi-SSID function, it is preferable that the wireless networks 5a, 5a, 5a,... With different SSIDs can be further deployed in the wireless network 5a deployed as a public wireless LAN service. A plurality of service providers of public wireless LAN services can deploy a wireless LAN with a common SSID managed by each service provider, and the coverage area can be improved.

  On the OSGi framework 15, bundles (22, 23,...) That provide individual functions to be described later operate. These bundles are managed in a remote server 35 to be described later which bundle is installed for management or contract. As a general function of the OSGi framework 15, the remote server 35 is inquired at a predetermined interval to inquire about the bundle installed in the gateway device 11 or the bundle of the setting to be installed. Can be downloaded, updated or additionally installed. Also, if there are bundles that are no longer needed for other reasons, such as contract termination, they are uninstalled from themselves.

  The gateway device 11 has an information delivery bundle 22 that can deliver data and commands from the OSGi framework 15 to the Native function unit 13 as the bundle. Data or commands passed in a predetermined format can be delivered to any functional unit on the Native functional unit 13 side in accordance with an instruction held by the data or command. The information delivery bundle 22 of the gateway device 11 according to the present invention reads setting information (SSID) included in at least an OSGi framework 15 when an SSID information management bundle 23 described later is added or updated and installed. The data is transferred to the Config information function unit 26.

  The gateway device 11 according to the present invention includes, as the above-described bundle, an SSID information management bundle 23 (23a, 23b, which includes setting information for each service provider that provides a public wireless LAN service using the wireless network 5a in an extractable format. 23c ...). Here, the setting information refers to SSID information, encryption method and password, frequency range to be used, address of the page to be authenticated, etc. required by the service provider who intends to provide public wireless LAN service. is there. Separate bundles 23a, 23b, 23c,... Are individually installed for each SSID of the wireless network to be deployed or for each service provider that provides a public wireless LAN service.

  An example in which this SSID information management bundle 23 is set for each service provider is shown in FIG. These are text generated according to a predetermined format. “RadiusAddress” is an address of an authentication server 37 of a service provider who intends to provide a public wireless LAN service. The gateway device 11 authenticates this address using the “RadiusKey” by the “chap” method, thereby serving as a part of the public wireless LAN service provided by the service provider. Although a single SSID may be used for each service provider, a plurality of SSIDs may be set as shown in the figure in order to individually deploy networks having different frequency ranges and communication methods. In addition to this, it may be possible to set more detailed information about the wireless LAN, such as wireless encryption methods such as WEP, WPA, and WPA2, passwords, and frequency ranges to be used. Further, although not shown in the drawing, when there is an access from a general user terminal 1 trying to access the wireless network 5a of the SSID, the general user terminal 1 is qualified to receive provision of the public wireless LAN service. An ID for authentication and a password for confirmation may be input and an address of a WEB page where authentication can be performed may be included.

  The remote server 35 is a server that distributes and redistributes a bundle in response to a request. The remote server 35 is installed in the carrier network 7 managed by a communication carrier that can take charge of the operation of the gateway device 11 according to the present invention in the external network 6. The bundle is delivered to the gateway device 11 in a highly secure environment without going through the Internet 8. Each gateway device 11 periodically connects to the remote server 35, inquires whether there is an update for the bundle installed in the OSGi framework 15, and if there is an update, downloads a new version bundle. ,install. Alternatively, if there is a bundle that is no longer necessary, the fact is notified to the OSGi framework 15 of the gateway device 11. In FIG. 1, an arrow is drawn so that the remote server 35 and the bundle on the OSGi framework 15 are virtually communicating with each other, but actually, the external network interface 19 controlled by the Native function unit 13 , And communicate with JNI 16.

  In the system according to the present invention, SSID information management bundles 23a, 23b, and 23c are included as bundles distributed from the remote server 35 described above. These SSID information management bundles 23 are distributed from the remote server 35 in accordance with the contract contents that the installer of the gateway device 11 contracts with the service provider that operates the remote server 35. For example, the content of the contract includes selection such as “provide for the service of company A but not for the service of company B”, or selection such as “provide on the condition of service β instead of service α of company A”. Make it possible. A customer information database 36 that can be referred to when providing by the remote server 35 exists in the operator network of the external network 6 so that these provided services can be managed. The remote server 35 that has received the inquiry from the gateway device 11 refers to this customer information database 36 to determine whether or not there is a necessary SSID information management bundle 23 or whether there is an update or the like, If there is a necessary SSID information management bundle 23, it is downloaded.

  An example of a table included in the customer information database 36 is shown in FIG. “User information” is an ID that can identify each gateway device 11 of a user who provides the gateway device 11 to the public wireless LAN service. Specifically, a communication carrier that manages the carrier network and provides a connection service to the Internet needs to be able to identify the gateway device 11 that is individual hardware. For example, an ID that separately has a table associated with a telephone number of a fixed telephone can be used. The “provided bundle” indicates the type of the SSID information management bundle 23 provided to the gateway device 11 in accordance with a contract with the contractor of the gateway device 11. That is, it represents the type of public wireless LAN service provided by the gateway device 11. The gateway device 11 in which the “A bundle” is installed expands the public wireless LAN service of the company A according to the setting information such as the SSID, and the “B bundle”, “C bundle”, “D bundle”, and “E bundle” are respectively The SSID information management bundle 23 which provides another public wireless LAN service is shown. As shown in the figure, one gateway device 11 may include a plurality of SSID information management bundles 23 and serve as a plurality of public wireless LAN service providing terminals.

  In the table above, “contract abolition plan presence / absence” means that there is a period limitation on the contract between the user of the gateway device 11 and the provider of the remote server 35, and the SSID by the gateway device 11 on the designated date. It means a flag indicating whether or not there is a procedure for terminating the provision of the public wireless LAN service corresponding to the information management bundle 23. This may be the end date of a one-month contract or one-year contract, or a stop date due to an application for active contract termination by the user of the gateway device 11 described above. When the “contract abolition schedule presence / absence” is “present”, the remote server 35 reaches or expires the “contract abolition date” for the gateway device 11 of the record, and the SSID information management bundle 23 (for example, the first row of the table) Is instructed to be deleted.

  When preparing the SSID information management bundle 23 so that it can be distributed by the remote server 35, the information delivery bundle 22 can read the setting information from the SSID information management bundle 23 and transmit it to the Config information function unit 26. According to the predetermined format. However, it is troublesome to manually form text that conforms to this format. For this reason, a telecommunications carrier that provides a system according to the present invention inputs necessary items to a service provider who intends to develop a public wireless LAN service by the gateway device 11, and then enters the text in a predetermined format. It is preferable to provide an output tool that can output the formed SSID information management bundle 23.

  On the other hand, the Config information function unit 26 of the gateway device 11 according to the present invention has allowed access from the outside in the past in order to allow the setting information of the wireless function unit 25 including the SSID from the OSGi framework 15 to be changed. There is a risk that a part of the security kept by refusing everything may be weakened. Therefore, when accepting a change from the OSGi framework 15, the Config information function unit 26 accepts only a change from the information delivery bundle 22 and does not accept any other change instruction from the JVM 14. It is desirable to set rights.

  Until a practitioner who operates the system and the remote server 35 according to the present invention provides a public wireless LAN service in response to a request from a service provider who intends to develop a public wireless LAN service using the existing gateway device 11 The procedure will be described using the flow of FIG. First, a practitioner (communication carrier) who implements the present invention as a pre-invention preparation installs the gateway device 11 at home or a sales office and provides an Internet connection service via the carrier network 7 of the carrier. Accepting a contract permitting the receiving user to open the wireless LAN by the gateway device 11 as a public service limitedly. The contract may not be limited to service providers, or may be a contract that limits service providers and other conditions. If the conditions are limited, a registration item is added to the customer information database 36 including that fact, or a separate table is prepared and recorded.

  Next (S101), the telecommunications carrier as the implementer provides the output tool to a service provider who intends to develop a public wireless LAN service. The carrier receives the output tool and inputs the setting information including the SSID, or directly inputs the setting information to the output tool through the web interface that can access the remote server 35 directly or indirectly. The SSID information management bundle 23 (23a, 23b, 23c...) Is output (S102). The remote server 35 refers to the customer information database 36 so that the SSID information management bundle 23 according to the contract conditions can be distributed to the gateway device 11 of the user who is contracted to provide for the public wireless LAN service. (S103).

  On the other hand, the gateway apparatus 11 having the OSGi framework 15 inquires of the remote server 35 about the presence or absence of a necessary bundle, and if there is a bundle that requires additional installation or update installation, downloads it from the remote server 35 as appropriate. As part of the gateway device 11 according to the present invention, the SSID information management bundle 23 is downloaded. At the initial time, the gateway apparatus 11 does not have the SSID information management bundle 23 installed (S111 → None). At this time, the gateway device 11 downloads from the remote server 35 all the SSID information management bundles 23 of the service providers permitted by the user of the gateway device 11 in a contract (S121). The downloaded SSID information management bundle 23 is checked for items that cannot be set, such as those having a grammatical error and those that include settings that are impossible in the gateway device 11 due to hardware specifications (S122). ). The SSID information management bundle 23 having the impossible items (S122 → Yes) is suspended without being passed to the information delivery bundle 22 (S123). Although the reserved SSID information management bundle 23 is not used, it may be resolved by re-distribution after update at a later date as in the flow described later, and is left as it is. If there is no SSID information management bundle 23 with no other non-configurable items in the downloaded file (S124 → No), the process waits until the next check (S125). If there is another SSID information management bundle 23 having no non-configurable items, the setting information is used for it (S124 → Yes). If there is no item that cannot be set, the setting information is used without any problem (S122 → No).

  For the SSID information management bundle 23 that has no non-configurable items, the information delivery bundle 22 reads the setting information included in the SSID information management bundle 23 (S131). The information delivery bundle 22 delivers the read setting information to the Config information function unit 26 of the Native function unit 13 (S132). In accordance with the access right setting, the Config information function unit 26 is configured to give security permission and permit transfer to the wireless function unit 25 if the setting information is transferred from the information transfer bundle 22. Therefore, the setting information is transferred to the wireless function unit 25 as it is (S133). At this time, it is determined whether or not the wireless LAN already set in the wireless function unit 25 has a setting having the same SSID name as the setting information transferred and using the same frequency range ( S134). If there is no wireless LAN in which they are the same (S134 → No), a public wireless LAN based on the SSID according to the delivered setting information is transmitted (S135). On the other hand, if there is a setting in the wireless LAN already set in the wireless function unit 25 that has the same SSID name as the transferred setting information and uses the same frequency range (S134 → Yes), After the setting is rewritten with the contents of the new setting information, the public wireless LAN is transmitted with the new setting (S136).

  Thereafter (S137 → S141), the gateway apparatus 11 periodically (S142) inquires of the remote server 35 whether or not the SSID information management bundle 23 has been updated. That is, since the SSID information management bundle 23 is installed at this stage (S111 → Yes), the remote server 35 is inquired and the already installed SSID information management bundle 23 is compared with the latest information in the remote server 35. (S112). If there is no difference (S112 → no difference), it is not necessary to download a new SSID information management bundle 23 (S113), and the system waits until the next update confirmation time (S114 → S141). If there is an SSID information management bundle 23 to be updated or added (S112 → with differences), it is downloaded from the remote server 35 (S121).

  Although not shown in the flow, in the process of S112, if the contract termination date has been reached for a part or all of the SSID information management bundle 23 by the customer information database 36 referred to by the remote server 35, the SSID An instruction to uninstall the information management bundle 23 is transmitted from the remote server 35 to the gateway device 11. The information delivery bundle 22 that has received the information transmits an instruction to the wireless function unit 25 to stop the transmission of the public wireless LAN of the SSID corresponding to the SSID information management bundle 23 through the Config information function unit 26. The wireless function unit 25 stops the public wireless LAN of the SSID that has been instructed to stop.
