Description

  The present invention relates to a remote setting system for setting a subscriber network terminator, which is a telecommunications line facility, from a remote location, in order to manage line-specific information and setting information of the subscriber network terminator for each subscriber line. The present invention relates to a remote setting system, a line management method, and a computer program.

  In recent years, Internet access using broadband lines has become widespread in office buildings, condominiums, and ordinary homes. A subscriber network terminator is installed in the home of a subscriber who is provided with telecommunication services from a telecommunication carrier for Internet access via this broadband line. A subscriber network termination device is installed in a subscriber's home, one for each subscriber line that connects the facilities of the telecommunications carrier and the subscriber's home, and terminates the network managed by the subscriber to provide the telecommunications business. Is a telecommunications line facility interconnected with a person's network. A subscriber network terminator is a telecommunications line facility installed by a telecommunications carrier to provide telecommunications services, and is installed in a subscriber's home, but the subscriber himself / herself is a subscriber network terminator directly. Since setting is not possible, ask the telecommunications carrier for remote setting.

  The remote setting of the subscriber network terminating device is performed as a response to a setting information request transmitted from the subscriber network terminating device from a remote setting system on the network accessible from the subscriber network terminating device. Subscriber line information is registered in the database held by the remote setting system, and the setting information of the subscriber network terminator connected to the subscriber line is associated with the subscriber line information. Is also registered. The operation of the subscriber line information is performed by the service order. For example, when a subscriber contracts with a telecommunications carrier to receive provision of telecommunications services, the service order “new line” is entered in the database server, so that a record of the new subscriber line is entered in the database. Is generated and the contract between the subscriber and the telecommunications carrier is terminated, the service order for “line abandonment” is entered and the record of the subscriber line to be abolished is deleted, or “ A value indicating the state of “invalid” is stored and the line is logically deleted.

On the other hand, there is a technique for inheriting original subscriber data as new subscriber data (see, for example, Patent Document 1). This technology takes over the subscriber data held in the electronic exchange on-line and in real time when the system program is changed in the electronic exchange.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a connection configuration between a remote setting system 1 and peripheral devices according to an embodiment of the present invention.
In the figure, a remote setting system 1 and a service order generation system 5 are connected to a network N which is a network such as the Internet. The subscriber network termination device 6 is connected to the network N via an edge router 7 by a subscriber line. The remote setting system 1 includes a center system 2, a plurality of subsystems 3, and a service order input interface server 4. In the present embodiment, the remote setting system 1 is described as including two subsystems 3, that is, the subsystem 3 a and the subsystem 3 b, but the number of subsystems 3 may be three or more. Hereinafter, “subscriber line” is also simply referred to as “line”.

  The remote setting system 1 manages setting information and the like of the subscriber network terminator 6 that is connected to one subscriber line. The remote setting is performed as a response to the setting information request transmitted by the subscriber network terminating device 6, and the subscriber network terminating device 6 periodically transmits a setting information request to the remote setting system 1, and the setting information request , The remote setting system 1 searches for setting information to be transmitted and returns it to the subscriber network terminating device 6. Therefore, as the number of subscriber network termination devices 6 increases, the remote setting request also increases. Therefore, the remote setting system 1 is assigned to the center system 2 that centrally manages the state of all subscriber lines (valid, invalid, being transferred, etc.) and itself so that response time delay due to high load does not occur. The load is distributed in a configuration including a plurality of subsystems 3 that manage only setting information of the subscriber network termination device 6 connected to the subscriber line.

  The service order input interface server 4 has an FTP (File Transfer Protocol) server function. By periodically performing batch processing, the service order input interface server 4 reads the service order file uploaded by FTP from the service order generation system 5 and performs processing. And data operations such as addition, registration, and deletion are performed on each table stored in the center system database server 21 and the subsystem database server 31.

The service order generation system 5 generates a service order from the input application contents, and uploads the generated service order file to the service order input interface server 4 by FTP.
The subscriber network termination device 6 is a device for connecting a terminal device in a subscriber premises to a network (for example, IPv6 network) in an optical fiber subscriber communication network, and has an HTTP client function and an HTTP server function. The subscriber network termination device 6 transmits a setting information request to the subsystem 3 that holds its own setting information, stores the setting information received in response to the request in its own non-volatile memory, and The operation according to the setting information is executed.

FIG. 2 is a functional block diagram of the center system 2 and the subsystem 3 according to the present embodiment.
The center system 2 includes a center system database server 21 and a subscriber network termination device interface server 22. The center system database server 21 stores a line state table T1 indicating the state of each subscriber line and a correspondence table T2 indicating information on which subsystem the setting information of the subscriber network terminating device 6 is registered. . The subscriber network termination device interface server 22 includes an HTTP server function unit 23 that realizes an HTTP (Hypertext Transfer Protocol) server function and an HTTP client function unit 24 that realizes an HTTP client function. Both the subscriber network terminator interface server 22 and the subscriber network terminator 6 are connected by a subscriber line via an edge router 7 (not shown) and have a TCP (Transmission Control Protocol) / IPv6 / HTTP protocol stack. Communicate using the interface used.

The subsystem 3 includes a subsystem database server 31 and a subscriber network termination device interface server 32. The subsystem database server 31 includes a setting information table T3 that holds setting information of the subscriber network termination device 6 connected to each subscriber line. The subscriber network terminator interface server 32 has the same functions as the subscriber network terminator interface server 22, and includes an HTTP server function unit 33 that realizes an HTTP server function and an HTTP client function unit 34 that realizes an HTTP client function. Prepare.
If the subsystem 3 is the subsystem 3a, the subsystem database server 31, the subscriber network termination device interface server 32, the HTTP server function unit 33, the HTTP client function unit 34, and the setting information table T3 are followed by a In the case of the subsystem 3b, a symbol b is added for description. For example, the subsystem 3a includes a subsystem database server 31a, a subscriber network termination device interface server 32a, an HTTP server function unit 33a, and an HTTP client function unit 34a, and the subsystem database server 31a stores a setting information table T3a. The same applies to the subsystem 3b.

Next, operation | movement of the remote setting system 1 of this Embodiment is demonstrated using FIGS.
FIG. 3 is a diagram illustrating an initial state of the remote setting system 1 before the subscriber network termination device 6 moves.
The line state table T1 held by the center system database server 21 of the center system 2 is a line state record composed of columns of subscriber ID, line ID, line state, line changing flag, line specific information, and change specific information. Thus, the subscriber ID and the line ID are used as the main keys. The subscriber ID is an identifier that uniquely identifies the subscriber, and the line ID is an identifier that uniquely identifies the subscriber line.
The status flag indicates the status of the subscriber line specified by the subscriber ID and the line ID. The status flag takes the values “invalid” and “valid”. When the line status record has the status flag “invalid”, the line having the line ID of the line status record is in an invalid state, and the setting value is input. And remote setting is not possible. The line change flag indicates a state in which a line change without changing the line ID is performed on the subscriber line specified by the subscriber ID and the line ID.
The line-specific information indicates information specific to the subscriber line, and one or more items can be set. The line change in progress flag takes values of “subsystem change (old line valid)” and “subsystem change (new line valid)”, and in the case of null, the line is not changed. Note that the line-specific information handles only one item for simplicity, and here, an IPv6 prefix uniquely assigned to the subscriber line is stored.
The change unique information is the line unique information of the subscriber line that becomes valid after the line change. Here, the IPv6 prefix applied after the line change is stored.

  In the correspondence table T2 held by the center system database server 21, the line specific information and the subsystem position information are registered in association with each other. The position information of the subsystem indicates the position of the subsystem 3 in which setting information about the subscriber network termination device 6 connected to the subscriber line for which the corresponding line specific information is used is registered. Note that the location information may indicate an address such as a URI (Universal Resource Identifier) of the subsystem 3, and the subscriber network termination device 6 is stored in an external device or an internal storage means. Information serving as a search key for reading an address may be used.

  The setting information table T3 held by the subsystem database server 31 of the subsystem 3 includes setting information records including columns of subscriber ID, line ID, line unique information, and setting information. The setting information is setting information of the subscriber network terminating device 6 connected to the subscriber line specified by the subscriber ID and the line ID, and one or more setting information can be set. Only deal with. The setting information stores, for example, ON / OFF of a DHCP (Dynamic Host Configuration Protocol) server function in the subscriber network terminating device 6.

  In the figure, in the line state table T1 held by the center system database server 21, the subscriber ID is “user_01”, the line ID is “line_01”, the line state is “valid”, and the line specific information is “prefix_01”. A line status record in which the line changing flag and the change unique information are null is registered. Further, the correspondence table T2 held by the center system database server 21 is associated with the line-specific information “prefix_01” and the subsystem position information “sub_01”, so that the line-specific information “prefix_02” and the subsystem position information “sub_02” are associated with each other. "Is registered in association with each other. It is assumed that the position information of the subsystem 3a is “sub_01” and the position information of the subsystem 3b is “sub_02”. In the setting information table T3a held by the subsystem database server 31a of the subsystem 3a, the subscriber ID is “user_01”, the line ID is “line_01”, the line specific information is “prefix_01”, and the setting information is “setting 1”. A setting information record is registered.

  When the subscriber network terminator 6 is connected to a subscriber line whose IPv6 prefix is “prefix_01” in the factory-shipped state, an HTTP request is sent to the specified URI of the subscriber network terminator interface server 22 of the center system 2. To send a setting information request (step S110). When the subscriber network termination device interface server 22 acquires the IPv6 prefix “prefix — 01” from the source IPv6 address of the received HTTP request, the subscriber network termination device interface server 22 accesses the center system database server 21, has the prefix in the line specific information, and A search is made as to whether or not a line state record having a flag “valid” exists in the line state table T1. If the corresponding line status record is found as a result of the search, the subscriber network terminating device interface server 22 searches the correspondence table T2, and the subsystem position corresponding to the line specific information in which the IPv6 prefix “prefix_01” is set. Information “sub — 01” is read (step S120). The subscriber network termination device interface server 22 sets the read location information as an HTTP response and returns it to the subscriber network termination device 6 (step S130).

  The subscriber network termination device 6 acquires the subsystem location information “sub_01” from the HTTP response returned from the subscriber network termination device interface server 22 and writes it in the internal memory. Subsequently, the subscriber network terminating device 6 transmits a setting information request by an HTTP request to the subscriber network terminating device interface server 32a specified by the acquired location information “sub_01” (step S140). When the subscriber network termination device interface server 32a obtains the IPv6 prefix “prefix_01” from the source IPv6 address of the received HTTP request, the subscriber network termination device interface server 32a searches the setting information table T3a using the prefix. When the corresponding setting information record is found, the setting information “setting 1” read from the setting information record is set in the HTTP response and returned (step S150).

  When the subscriber network terminating device 6 receives the HTTP response returned from the subscriber network terminating device interface server 32, the subscriber network terminating device 6 acquires the setting information “setting 1” from the received HTTP response and writes it in the internal memory. As described above, the setting of the subscriber network termination device 6 becomes effective, and the subscriber can connect a personal computer, a set-top box, etc. to the subscriber network termination device 6 and connect to the Internet through the subscriber line. Thereafter, the subscriber network terminating device 6 periodically sends a setting information request to the subsystem 3a using the subsystem location information stored therein, acquires the latest setting information and holds it in the interior. Update the setting information.

FIG. 4 is a diagram showing an operation procedure when the remote setting system 1 receives a service order for line change.
As subscribers move, they will stop using the current line and use the new address. When a subscriber line is changed due to moving or the like, the line ID may or may not change between the line before moving and the line after moving. The case where the line ID is not changed is due to, for example, moving within the same building (moving from room 101 in the apartment to room 403), an interface failure of the edge router 7 in which the subscriber line is accommodated, etc. This is a case of a line change where there is no movement in a very short distance or location, such as a change in accommodation to another interface of the same edge router 7. In such a case, there is a case in which only the line specific information (IPv6 prefix in the present embodiment) is changed without changing the line ID. In these cases, there is no change in the subscriber ID and the line ID, which are the main keys of the management table, before and after the line change. In the following, a case will be described in which moving is performed without changing the line ID and the subsystem 3 holding the setting information of the subscriber network terminating device 6 is changed.

  When the application details regarding the transfer of the target subscriber is input to the service order generation system 5 by the contact person of the telecommunications carrier, the service order generation system 5 generates a service order file from the input information, It is transmitted to the service order input interface server 4. Here, a service order file of a change request in which the subscriber ID “user_01”, the line ID “line_01”, and the changed line specific information “prefix_02” are set is generated and uploaded to the service order input interface server 4 It is assumed (step S210).

  The service order input interface server 4 periodically processes the service order file uploaded from the service order generation system 5. When the service order described in the service order file is a change request, the service order input interface server 4 determines from the line status table T1 in the center system database server 21 the subscriber ID “ A line state record having a line state of “valid” with “user_01” and line ID “line_01” as a primary key is searched. If a line status record corresponding to the subscriber ID and the line ID is found as a result of the search, the changed line specific information “prefix_02” set in the service order is added to the change specific information of the found line status record. Is written (step S220).

  Next, the service order input interface server 4 acquires the line specific information “prefix_01” from the found line state record, searches the correspondence table T2 using the line specific information as a key, and the corresponding subsystem position information “sub_01”. Is read. Further, the service order input interface server 4 searches the correspondence table T2 using the changed line specific information “prefix — 02” set in the service order as a key, and reads the corresponding subsystem position information “sub — 02”. The service order input interface server 4 reads the subsystem position information “sub_01” read using the line unique information of the found line state record as a key and the line unique information “prefix_02” set in the service order as a key. The unique information subsystem position information “sub — 02” is compared, and since these are different, it is determined that the line change is made across the subsystems 3 (step S230).

  If the service order input interface server 4 determines that the line change has occurred across the subsystems 3, the service order input interface server 4 sets “change between subsystems (valid old line)” to the line change flag in the line state record found in step S220. The indicated value is written (step S240).

5 and 6 are diagrams showing an operation procedure of the remote setting system 1 when the subscriber network termination device 6 is connected to the moving destination.
In FIG. 5, when the subscriber connects the subscriber network termination device 6 in the factory shipment state to the moving destination subscriber line (step S <b> 310), the subscriber network termination device 6 becomes the subscriber network termination device of the center system 2. A setting information request is transmitted to the specified URI of the interface server 22 by an HTTP request.

  The subscriber network terminating device interface server 22 acquires the IPv6 prefix “prefix — 02” from the source IPv6 address of the received HTTP request. The subscriber network termination device interface server 22 reads the subsystem location information “sub — 02” corresponding to the line-specific information in which the acquired IPv6 prefix “prefix — 02” is set from the correspondence table T2, and sets it in the HTTP response to the subscriber. It returns to the network termination device 6 (step S320).

  Further, the subscriber network terminating device interface server 22 has a line state record having the acquired IPv6 prefix in the line specific information and having a state flag “valid” from the line state table T1 in the center system database server 21. Search for. If the corresponding line status record is not found as a result of the search, the subscriber network terminating device interface server 22 has the IPv6 prefix “prefix — 02” in the changed line specific information and the status flag is “valid”. Whether the status record is in the line status table T1 is searched. When a corresponding line state record is found (hereinafter, the found line state record in the line state table T1 is referred to as “detected line state record”), the line changing flag in the detected line state record is referred to. If “change between subsystems (valid old line valid)” is set in the line changing flag, it is determined that the setting information should be moved across the subsystems 3 (step S330).

  If it is determined that the setting information should be moved across the subsystem 3, the subscriber network terminating device interface server 22 adds the line specific information “prefix_01” and the change specific information “prefix_02” acquired from the detected line state record. Corresponding subsystem position information “sub — 01” and “sub — 02” are read from the correspondence table T2 (step S340). The subscriber network terminating device interface server 22 accesses the subsystem 3a specified by the subsystem position information “sub_01” read in correspondence with the line specific information “prefix_01”, and obtains the subscriber ID obtained from the detected line state record. Using the “user_01” and the line ID “line_01” as primary keys, the setting information record in the setting information table T3a held by the subsystem database server 31a is searched. The search may be performed using the line specific information “prefix — 01” acquired from the detected line state record instead of the subscriber ID and the line ID. The subscriber network terminating device interface server 22 reads the setting information “setting 1” from the setting information record of the setting information table T3a found as a result of the search.

  Subsequently, the subscriber network terminating device interface server 22 accesses the subsystem 3b specified by the subsystem position information “sub_02” read corresponding to the change specific information “perfix_02”, and acquires it from the detected line state record. A setting information record having a subscriber ID “user_01” and a line ID “line_01” as main keys is added. Then, the IPv6 prefix “prefix — 02” acquired from the setting information request received in step S320 is added to the line specific information of the added setting information record, and the setting information “setting 1” read from the setting information record of the setting information table T3a is set as setting information. Is written. Thereafter, the subscriber network terminating device interface server 22 deletes the setting information record having the subscriber ID “user_01” and the line ID “line_01” as the main keys, found as a result of searching the setting information table T3a (step S350). .

  In FIG. 6, the subscriber network terminating device interface server 22 rewrites the line specific information of the detected line state record to the value of the current change specific information, sets null to the change specific information, and further sets a line changing flag. Is rewritten to a value indicating "change between subsystems (new line valid)" (step S360).

  Thereafter, the subscriber network terminating device 6 acquires the setting information from the subsystem 3b by the same procedure as in FIG. In other words, the subscriber network terminating device 6 reads the subsystem location information “sub — 02” notified from the HTTP response from the subscriber network terminating device interface server 22 from the internal memory, and is specified by the read location information “sub — 02”. A setting information request is transmitted to the subscriber network termination device interface server 32b by an HTTP request. The subscriber network terminator interface server 32b reads the setting information “setting 1” from the setting information table T3a using the IPv6 prefix “prefix — 02” acquired from the source IPv6 address of the HTTP request as a key, and returns it by an HTTP response. The subscriber network terminator 6 acquires the setting information “setting 1” from the HTTP response returned from the subscriber network terminator interface server 32 and writes it in the internal memory.

FIG. 7 shows an operation procedure when receiving a service order for canceling the moving source line.
The service order generation system 5 uploads to the service order input interface server 4 the service order of the line abolition request in which the subscriber ID “user_01”, the line ID “line_01”, and the line specific information “prefix_01” are set (step). S410). When the service order described in the service order file is a line abolition request, the service order input interface server 4 uses the subscriber ID set in the service order from the line state table T1 in the center system database server 21. A line status record having “user_01” and line ID “line_01” as primary keys is searched. As a result of the search, if the line status record corresponding to the subscriber ID and the line ID is found, and “change between subsystems (new line valid)” is set in the line change flag of the line status record, the line A null value is set in the line changing flag in the status record (step S420).

  In the above description, the case where the setting information is taken over across the subsystems 3 has been described. However, the case where the setting information is taken over in the same subsystem 3 can be similarly performed. That is, in step S230 of FIG. 4, the subsystem position information read out using the line-specific information in the setting information record of the setting information table T3 corresponding to the subscriber ID and line ID set in the service order as a main key; If the subsystem position information read using the changed line-specific information set in the service order as the primary key is the same, the line change flag in the setting information record of the detected setting information table T3 indicates “change within the same subsystem”. Set the value indicating (Old line valid). In step S350 in FIG. 5, no new setting information record is added. In step S360 in FIG. 6, the line change flag in the detected line status record is set to “change between same subsystems (new line valid). ) ", The value of the line specific information is rewritten to the value of the current change specific information, and null is set in the change specific information.

  According to the above-described embodiment, when a line change service order is received, whether or not the line change does not change the line identifier. If the line change does not change the line identifier, each line is managed before and after the line change. Determine whether the subsystem will change. When it is detected that the subscriber network terminator 6 is installed on the new line, the setting information of the subscriber network terminator 6 is transferred from the subsystem 3 that manages the old line to the subsystem 3 that manages the new line. By being moved (not copied), it can be assured that only one setting information regarding an arbitrary line identifier exists through all the subsystems 3.

  Conventionally, in a configuration in which setting information of a subscriber network termination device is distributed and held in a plurality of subsystems, when the moving source and the moving destination are managed by different subsystems, the moving source information is changed to the subsystem A. However, there is a situation in which there are two records of valid setting information for the new and old lines, such as subsystem B as the moving destination information. However, since the subscriber is charged for the available line, if the moving source information and moving destination information exist as records in different subsystems, both the old and new lines can be used. It was judged that there was a risk of being charged twice. In addition, since the timing for copying the setting information from the old line to the new line is at the time of service order reception in the past, even if there is a change in the setting information on the old line after duplication, it will not be transferred to the new line There was also a problem.

  The remote setting system 1 of the above embodiment is changed when a line change that does not change the line ID occurs even if the setting information of the subscriber network terminating device 6 is distributed to a plurality of subsystems. It becomes possible to take over the setting information of the line before the change to the subscriber terminating device of the subsequent line. Further, since the record of the unused line is not held in the setting information table T3 of the subsystem 3, there is no possibility that the processing such as charging based on the information in the setting information table T3 is performed twice. Correct billing is possible. Even if the setting information of the old line is changed after receiving the line change service order, the setting can be taken over when the subscriber network terminating device 6 is connected to the new line.
