JP6760894B2 - Restart instruction notification device and restart instruction notification method - Google Patents

Description

The present invention relates to a restart instruction notification device and a restart instruction notification method.

Conventionally, an edge router connected to a home gateway has a filter function for a security function. The filter function is a function that dynamically stores the IP address of the subordinate home gateway and blocks communication with a source other than the stored IP address.

When such an edge router is restarted for reasons such as failure recovery, the filter settings may be lost. In this case, unless the home gateway is restarted, the edge router does not have a chance to relearn the IP address of the home gateway, and the communication remains blocked.

Several methods have been proposed so that the edge router does not lose the filter settings in this way. For example, a method of holding information in the non-volatile memory of an edge router and reading the setting contents at the time of restart, and a network device such as a router or an operating system restarts the edge router by TRAP information such as IF UP. A method has been proposed in which information is automatically flowed in by recognizing.

"Boot Options", [online], [Search on July 4, 2017], Internet <https://infoproducts.alcatel-lucent.com/html/0_add-hf/93-0070-10-01/7750_SR_OS_System_Basics_Guide/ bof.html ＞

However, with the conventional technology, there is a problem that the communication of the home gateway may not be restored easily and quickly. For example, the method of holding information in the non-volatile memory of an edge router and reading the setting contents at the time of restart is not always applicable because edge routers that do not have such a function in the first place are commercially available. Further, even if the edge router has such a function, the setting may not be correctly maintained depending on the state at the time of restart.

Also, for example, in the method of recognizing the restart of the edge router and automatically flowing the information, the edge router does not need to hold the setting information, but the operating system needs to know the setting status of each router. , It becomes a complicated mechanism.

In order to solve the above-mentioned problems and achieve the object, the restart instruction notification device of the present invention identifies a user under the edge router when the restart of the edge router is detected, and relates to the user. Using the acquisition unit for acquiring information and the information about the user acquired by the acquisition unit, the terminal to the terminal owned by the user or the home gateway installed in the user's home is described via a mobile network. It is characterized by having an instruction unit for instructing the restart of the home gateway.

Further, the restart instruction notification method of the present invention is a restart instruction notification method executed by the restart instruction notification device, and when the restart of the edge router is detected, the user under the edge router is notified. With respect to the terminal owned by the user or the home gateway installed in the user's home by using the acquisition step of identifying and acquiring the information about the user and the information about the user acquired by the acquisition step. It is characterized by including an instruction step of instructing the restart of the home gateway via a mobile network.

According to the present invention, there is an effect that the communication of the home gateway can be easily and quickly restored.

Hereinafter, embodiments of the restart instruction notification device and the restart instruction notification method according to the present application will be described in detail with reference to the drawings. It should be noted that this embodiment does not limit the restart instruction notification device and the restart instruction notification method according to the present application.

[First Embodiment]
In the following embodiments, the configuration of the communication system, the configuration of the restart instruction notification device, the communication system, and the processing flow in the restart instruction notification device according to the first embodiment will be described in order, and finally, the first The effect of the embodiment will be described.

[Communication system configuration]
First, the communication system according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram showing an example of a configuration of a communication system according to the first embodiment. The communication system according to the first embodiment includes a restart instruction notification device 10, an ER (Edge Router) 20, an SNMP (Simple Network Management Protocol) server 30, a customer information DB (Data Base) 40, and a notification destination information DB 50. It has a mail server 60, a user mobile terminal 70, an HGW (Home Gateway) 80, and a DHCP server 90. The configuration shown in FIG. 1 is only an example, and the specific configuration and the number of each device are not particularly limited.

Here, it is assumed that the restart instruction notification device 10, the notification destination information DB 50, the mail server 60, and the user mobile terminal 70 are mainly devices on the mobile operator side that communicate via the mobile network. Further, it is assumed that the ER20, the SNMP server 30, the customer information DB 40, the HGW 80, and the DHCP server 90 are devices on the fixed network operator side that mainly perform communication via the fixed network.

When the restart instruction notification device 10 receives the information of the restarted ER20 from the SNMP server 30, it acquires the user identification information under the restarted ER20 from the customer information DB 40, and moves the user that matches the acquired user identification information. Information on the terminal 70 (for example, an e-mail address, etc.) is acquired from the notification destination information DB 50. Then, the restart instruction notification device 10 transmits a message instructing the restart of the HGW 80 to the e-mail address included in the acquired information of the user mobile terminal 70.

The ER20 is a router that accommodates users in a fixed network service. Further, the ER20 has a filter function for ensuring security in addition to a basic transfer function such as a DHCP relay function. The ER20 dynamically stores the IP address of the HGW 80 under its control during the DHCP address payout sequence by the filter function, and blocks communication with other sources as the transmission source. Further, when the ER20 is restarted for reasons such as failure recovery, the filter settings are lost.

The SNMP server 30 monitors the state of the ER 20 and detects various abnormalities. When the SNMP server 30 detects the restart of the ER20, it notifies the restart instruction notification device 10 of the information of the restarted ER20.

The customer information DB 40 stores information about a fixed network user who has a contract with a fixed network operator. For example, the customer information DB 40 stores at least the user identification information under the control of the ER 20. The notification destination information DB 50 stores information about a mobile user who has a contract with the mobile operator. For example, the notification destination information DB 50 stores at least an e-mail address as information of the user mobile terminal 70 in association with the user identification information.

When the mail server 60 receives the mail addressed to the user mobile terminal 70, the mail server 60 delivers the mail to the destination user mobile terminal 70. The user mobile terminal 70 is a terminal owned by a user such as a smartphone, a tablet, or a mobile phone. The HGW 80 is a device installed at the user's home when using the fixed network service, and is used for a normal ISP (Internet Services Provider) connection or the like. Here, it is assumed that the user who owns the user mobile terminal 70 is a user of the fixed network, and the HGW 80 is provided at home.

The DHCP server 90 issues an IP address to the user's HGW 80 in response to a request from the HGW 80. Here, the process when the DHCP server 90 issues the IP address of the HGW 80 will be described with reference to FIG. FIG. 2 is a diagram illustrating a process when the DHCP server issues an IP address of the HGW.

As shown in FIG. 2, when the HGW 80 requests the IP address to be issued, when the ER20 receives the DHCP Discover sent by the HGW 80, it unconditionally relays the DHCP Discover message and transmits it to the DHCP server 90 ( (1) to (3) of FIG. 2). Subsequently, when the ER20 receives the DHCP operator including the determined IP setting information candidate from the DHCP server 90, the DHCP server transfers the DHCP operator to the HGW80 (see (4) and (5) in FIG. 2).

Then, the HGW 80 receives the DHCP office and confirms the candidates of the IP setting information included in the DHCP office. Then, if the candidate for the IP setting information can be accepted, the HGW 80 further transmits a DHCP Request to request the DHCP server 90 to secure the IP setting information (see (6) in FIG. 2). ..

Then, when the ER20 receives the DHCP Request, the DHCP Request learns the IP address of the HGW 80, sets a filter to pass the communication with the HGW 80 as the source, and transfers the DHCP Request to the DHCP server 90 (FIG. 2). (7), (8)). Then, the DHCP server 90 notifies the HGW 80 of the ACK signal including the secured IP setting information via the ER20 (see (9) and (10) of FIG. 2). Then, the HGW 80 that has received the ACK signal sets the IP setting information issued by the ACK signal in its own network interface and receives the communication service.

In this way, the ER20 learns the IP address of the HGW80 and sets the filter to pass the communication with the HGW80 as the source. However, if the ER20 is restarted for reasons such as failure recovery, the filter is set. The settings of are lost. In such a case, for example, as illustrated in FIG. 3, since the ER20 loses the filter setting contents after the restart, the packet from the HGW 80 is blocked. When the ER20 receives a packet from the service server 100 that provides a predetermined service to the HGW80, it depends on the implementation of the ER20 whether the downlink communication is possible or blocked in the same manner as the uplink communication. .. FIG. 3 is a diagram illustrating a process when the filter settings are lost in the edge router after restarting.

In this way, when the filter settings are lost, the ER20 does not have a chance to relearn the IP address of the HGW 80 unless the HGW 80 throws the DHCP Discover again, and the communication remains blocked. In addition, in order to suppress the load on the DHCP server 90, the lease period of the IP address issued to the HGW 80 is usually set to be long (for example, several hours), and in such a situation, the user May suffer disadvantages without noticing that the NW is unavailable for a long period of time. Therefore, when the ER20 loses the filter settings, the DHCP 80 wants to transmit the DHCP Discover as soon as possible.

In the restart instruction notification device 10 according to the first embodiment, when the restart of the ER 20 is detected, the user under the ER 20 is specified, the information about the user is acquired, and the information about the user is used. Then, the user mobile terminal 70 owned by the user is instructed to restart the HGW 80 via the mobile network. As a result, in the restart instruction notification device 10 according to the first embodiment, the user can be notified in a timely manner that the IP address of the HGW 80 needs to be issued again, and as a result, the DHCP Discover is promptly sent to the HGW 80. It is possible to make a call to prevent the NW from being unavailable for a long time, and to easily and quickly restore the communication of the DHCP80.

[Configuration of restart instruction notification device]
Next, the configuration of the restart instruction notification device 10 shown in FIG. 1 will be described with reference to FIG. FIG. 4 is a block diagram showing a configuration of a restart instruction notification device according to the first embodiment. As shown in FIG. 4, the restart instruction notification device 10 includes a communication processing unit 11, a control unit 12, and a storage unit 13. The processing of each of these parts will be described below.

The communication processing unit 11 controls communication related to various information exchanged with the SNMP server 30, the mail server 60, and the like. For example, the communication processing unit 11 receives the information of the ER20 restarted from the SNMP server 30. In addition, the communication processing unit 11 transmits an instruction to send a message prompting the user mobile terminal 70 to restart the HGW 80 to the mail server 60.

In addition, the storage unit 13 stores data and programs required for various processes by the control unit 12. For example, the storage unit 13 is a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory (Flash Memory), or a storage device such as a hard disk or an optical disk.

The control unit 12 has an internal memory for storing a program that defines various processing procedures and the like and required data, and executes various processing by these. However, the control unit 12 is particularly closely related to the present invention. It has an acquisition unit 12a and an instruction unit 12b.

When the restart of the ER 20 is detected, the acquisition unit 12a identifies a user under the ER 20 and acquires information about the user. For example, when the acquisition unit 12a receives the identification information of the restarted ER20 from the SNMP server 30, the acquisition unit 12a acquires the user identification information under the restarted ER20 from the customer information DB 40.

For example, the customer information DB 40 stores at least the "ER identification information" that identifies the ER 20 and the "user identification information" that identifies the user under the ER 20 in association with each other, as illustrated in FIG. To explain with reference to the example of FIG. 5, for example, the customer information DB 40 stores the ER identification information “ER1” and the user identification information “user A” in association with each other. This means that "User A" exists under ER20 identified by "ER1".

Then, the acquisition unit 12a acquires information (for example, an e-mail address) of the user mobile terminal 70 that matches the user identification information acquired from the customer information DB 40 from the notification destination information DB 50.

For example, the notification destination information DB 50 stores at least the "user identification information" and the "email address" of the user mobile terminal 70 owned by the user in association with each other, as illustrated in FIG. To explain with reference to the example of FIG. 6, for example, the notification destination information DB 50 stores the user identification information “user A” and the e-mail address “XXX” in association with each other. This means that the e-mail address of the user mobile terminal 70 owned by "user A" is "XXX".

The instruction unit 12b instructs the user mobile terminal 70 owned by the user to restart the HGW 80 via the mobile network by using the information about the user acquired by the acquisition unit 12a. For example, the instruction unit 12b sends a message instructing the restart of the HGW 80 to the user mobile terminal 70 via the mail server 60 by using the e-mail address acquired by the acquisition unit 12a.

Here, the entire processing flow in the communication system will be described with reference to FIG. 7. FIG. 7 is a diagram illustrating an overall processing flow in the communication system according to the first embodiment. As an initial state in FIG. 7, it is assumed that the ER20 has been restarted and the filter setting contents have been lost, so that the communication from the HGW 80 is blocked by the filter function.

First, when the SNMP server 30 detects the restart of the ER20, it notifies the restart instruction notification device 10 of the information of the restarted ER20 (see (1) and (2) of FIG. 7). Then, when the restart instruction notification device 10 receives the information of the restarted ER20 from the SNMP server 30, it acquires the user identification information under the restarted ER20 from the customer information DB 40 and matches the acquired user identification information. Information (for example, an e-mail address) of the user mobile terminal 70 is acquired from the notification destination information DB 50 (see (3) and (4) in FIG. 7).

Then, the restart instruction notification device 10 transmits an instruction to send a notification prompting the restart of the HGW 80 to the mail address included in the acquired information of the user mobile terminal 70 (see (5) in FIG. 7). .. When the mail server 60 receives the instruction to send the notification prompting the restart of the HGW 80 from the restart instruction notification device 10, the mail server 60 notifies the user mobile terminal 70 of the notification prompting the restart of the HGW 80 (see (6) in FIG. 7). ..

After that, the user 110 of the user mobile terminal 70 recognizes the notification prompting the restart of the HGW 80 and executes an operation for restarting the HGW 80 (see (7) in FIG. 7). Then, when the restart is executed, the HGW 80 transmits the DHCP Discover to the DHCP server 90 and pays a series of IP addresses until the DHCP Ac is received from the DHCP server 90, as described in FIG. 2 described above. The process of issuing is performed, and the filter function of the ER20 is made to relearn the IP address of the DHCP80 (see (8) in FIG. 7).

As described above, in the restart instruction notification device 10 according to the first embodiment, the user can be notified in a timely manner that the IP address of the HGW 80 needs to be issued again, and as a result, the DHCP Discover is promptly notified to the HGW 80. Is transmitted to prevent the NW from being unavailable for a long time, and it is possible to easily and quickly restore the communication of the DHCP80. In addition, by linking customer information that the mobile network and the fixed network have separately, the mobile network side notifies the user who is affecting the fixed network service, and the fixed network service interruption time. Can be shortened.

[Process flow of restart instruction notification device]
Next, the flow of processing of the restart instruction notification device 10 according to the first embodiment will be described with reference to FIG. FIG. 8 is a flowchart illustrating processing by the restart instruction notification device according to the first embodiment.

As shown in FIG. 8, the acquisition unit 12a of the restart instruction notification device 10 acquires the information of the restarted ER20 from the SNMP server 30 (step S101), and the user identification information under the restarted ER20 is stored in the customer information DB 40. (Step S102).

Then, the acquisition unit 12a acquires the e-mail address of the user mobile terminal 70 that matches the user identification information acquired from the customer information DB 40 from the notification destination information DB 50 (step S103). After that, the instruction unit 12b instructs the user to restart the HGW 80 by using the e-mail address acquired by the acquisition unit 12a (step S104). Specifically, the instruction unit 12b uses the e-mail address to send a message instructing the restart of the HGW 80 to the user mobile terminal 70 via the mail server 60.

[Effect of the first embodiment]
As described above, in the restart instruction notification device 10, when the restart of the ER 20 is detected, the user under the ER 20 is specified, the information about the user is acquired, and the user uses the information about the user. Instructs the owned user mobile terminal 70 to restart the HGW 80 via the mobile network. As a result, the restart instruction notification device 10 according to the first embodiment can notify the user in a timely manner that the IP address of the HGW 80 needs to be issued again, and as a result, promptly notifies the DHCP 80 of the DHCP Discover. By making a call, it is possible to prevent the NW from being unavailable for a long time, and to easily and quickly restore the communication of the DHCP80.

Further, the restart instruction notification device 10 acquires the e-mail address of the user mobile terminal 70 as information about the user, and transmits a message instructing the user mobile terminal 70 to restart the HGW 80 using the e-mail address. Therefore, it is possible to urge the user to restart the HGW 80 by using a contact means that can contact the user instead of the fixed network side where the abnormality is occurring.

[Second Embodiment]
In the first embodiment described above, the case of transmitting a message instructing the restart of the HGW 80 to the user mobile terminal 70 by using the e-mail address has been described, but the present invention is not limited to this. For example, a signal instructing the HGW 80 to restart may be directly transmitted, and the HGW 80 may be instructed to restart automatically.

Therefore, in the following, the case where the restart instruction notification device 10A according to the second embodiment directly transmits a signal instructing the HGW 80 to restart and instructs the HGW 80 to restart automatically. explain. The same configuration and processing as the communication system according to the first embodiment will not be described.

FIG. 9 is a diagram illustrating an overall processing flow in the communication system according to the second embodiment. As shown in FIG. 9, the restart instruction notification device 10A has an acquisition unit 12a and an instruction unit 12b.

The acquisition unit 12a acquires the notification destination information of the HGW 80 installed in the user's home as information about the user. In addition, the instruction unit 12b transmits a signal instructing the HGW 80 to restart using the notification destination information of the HGW 80 acquired by the acquisition unit 12a.

First, when the SNMP server 30 detects the restart of the ER20, it notifies the restart instruction notification device 10A of the information of the restarted ER20 (see (1) and (2) of FIG. 9). Then, when the acquisition unit 12a of the restart instruction notification device 10A receives the information of the restarted ER20 from the SNMP server 30, it acquires the user identification information under the restarted ER20 from the customer information DB 40, and acquires the acquired user identification. User information that matches the information (for example, identification information of the HGW 80 installed in the user's home) is acquired from the notification destination information DB 50 (see (3) and (4) of FIG. 9).

Here, an example of the table stored in the notification destination information DB 50 will be described with reference to FIG. FIG. 10 is a diagram showing an example of a table stored in the notification destination information DB. As illustrated in FIG. 10, for example, the notification destination information DB 50 stores at least "user identification information" and "HGW identification information" that identifies the HGW 80 in association with each other. To explain with reference to the example of FIG. 10, for example, the notification destination information DB 50 stores the user identification information “user A” and the HGW identification information “HGW1” in association with each other. This means that the identification information of the HGW 80 installed in the home of the "user A" is "HGW1".

Then, the acquisition unit 12a acquires the notification destination information of the HGW 80 based on the acquired identification information of the HGW 80. For example, the acquisition unit 12a may further acquire the notification destination information of the HGW 80 from the notification destination information DB 50 based on the acquired identification information of the HGW 80. Further, the acquisition unit 12a may store, for example, the notification destination information of each HGW 80 in the storage unit 13 in the restart instruction notification device 10A in association with the identification information of the HGW 80, and read it from the storage unit 13. Further, the acquisition unit 12a acquires, for example, an IP address, a port number, or the like for LTE (Long Term Evolution) of the HGW 80 as notification destination information.

Then, the acquisition unit 12a issues a signal transmission instruction to the instruction unit 12b to urge the HGW 80 included in the acquired user information to restart (see (5) in FIG. 9). Subsequently, the instruction unit 12b notifies the HGW 80 of a signal prompting the HGW 80 to restart by a mobile communication radio wave (for example, LTE or the like) (see (6) in FIG. 9).

After that, the HGW 80 receives a signal prompting the restart, and when the restart is automatically executed, a series of IP addresses from the transmission of the DHCP Discover to the DHCP server 90 to the reception of the DHCP Ac from the DHCP server 90. Is performed, and the filter function of the ER20 is made to relearn the IP address of the DHCP80 (see (7) in FIG. 9).

In this way, the restart instruction notification device 10A according to the second embodiment acquires the notification destination information of the HGW 80 installed in the user's home, and uses the notification destination information of the HGW to the HGW 80. And sends a signal instructing to restart. Therefore, it is possible to directly transmit a signal instructing the HGW 80 to restart and instruct the HGW 80 to restart automatically.

[Third Embodiment]
In the second embodiment described above, a case has been described in which a signal instructing the HGW 80 to restart is directly transmitted and the HGW 80 is instructed to restart automatically, but the present invention is not limited to this. Absent. For example, the user mobile terminal 70 may be relayed to send a signal instructing the HGW 80 to restart, and the HGW 80 may be instructed to restart automatically.

Therefore, in the following, the restart instruction notification device 10B according to the third embodiment relays the user mobile terminal 70 to transmit a signal instructing the HGW 80 to restart, and automatically restarts the HGW 80. The case of instructing to start will be described. The same configuration and processing as those of the communication system according to the first and second embodiments will not be described.

FIG. 11 is a diagram illustrating an overall processing flow in the communication system according to the third embodiment. As shown in FIG. 11, the restart instruction notification device 10B has an acquisition unit 12a and an instruction unit 12b.

The acquisition unit 12a acquires the notification destination information of the user mobile terminal 70 as information about the user. Further, the instruction unit 12b transmits a signal instructing the HGW 80 to restart the HGW 80 via the user mobile terminal 70 by using the notification destination information of the user mobile terminal 70 acquired by the acquisition unit 12a.

First, when the SNMP server 30 detects the restart of the ER20, it notifies the restart instruction notification device 10B of the information of the restarted ER20 (see (1) and (2) of FIG. 11). Then, when the acquisition unit 12a of the restart instruction notification device 10B receives the information of the restarted ER20 from the SNMP server 30, it acquires the user identification information under the restarted ER20 from the customer information DB 40, and acquires the acquired user identification. Information on the user mobile terminal 70 of the user that matches the information (for example, identification information of the user mobile terminal 70) is acquired from the notification destination information DB 50 (see (3) and (4) in FIG. 11).

Here, an example of the table stored in the notification destination information DB 50 will be described with reference to FIG. FIG. 12 is a diagram showing an example of a table stored in the notification destination information DB. As illustrated in FIG. 12, for example, the notification destination information DB 50 stores at least "user identification information" and "mobile terminal information" that identifies the user mobile terminal 70 owned by the user in association with each other. To explain with reference to the example of FIG. 12, for example, the notification destination information DB 50 stores the user identification information "user A" and the mobile terminal information "mobile terminal A" in association with each other. This means that the identification information of the user mobile terminal 70 owned by "user A" is "mobile terminal A".

Then, the acquisition unit 12a acquires the notification destination information of the user mobile terminal 70 based on the acquired identification information of the user mobile terminal 70. For example, the acquisition unit 12a may further acquire the notification destination information of the user mobile terminal 70 from the notification destination information DB 50 based on the acquired identification information of the user mobile terminal 70. Further, for example, the acquisition unit 12a stores the notification destination information of each user mobile terminal 70 in the storage unit 13 in the restart instruction notification device 10B in association with the identification information of the user mobile terminal 70, and stores the storage unit 13 in association with the identification information of the user mobile terminal 70. You may read from. The acquisition unit 12a acquires, for example, the LTE IP address and port number of the user mobile terminal 70 as notification destination information.

Then, the acquisition unit 12a issues a signal transmission instruction to the user mobile terminal 70 included in the information of the user mobile terminal 70 acquired by the acquisition unit 12a to prompt the user mobile terminal 70 to restart the HGW 80 (see (5) in FIG. 11). ). Subsequently, the instruction unit 12b notifies the user mobile terminal 70 of a signal prompting the restart of the HGW 80 by a mobile communication radio wave (for example, LTE or the like) (see (6) in FIG. 11).

After that, the user mobile terminal 70 notifies the HGW 80 of the received signal prompting the restart of the HGW 80 by Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like (see (7) in FIG. 11). It is assumed that the HGW 80 has a function of receiving radio such as Wi-Fi and Bluetooth, and the user mobile terminal 70 has a signal relay function.

When the HGW 80 receives the signal prompting the restart and automatically executes the restart, the HGW 80 pays a series of IP addresses from the transmission of the DHCP Discover to the DHCP server 90 to the reception of the DHCP Ac from the DHCP server 90. The process of issuing is performed, and the filter function of the ER20 is made to relearn the IP address of the DHCP80 (see (8) in FIG. 11).

As described above, in the restart instruction notification device 10B according to the third embodiment, the notification destination information of the user mobile terminal 70 is acquired, and the acquired notification destination information of the user mobile terminal 70 is used to use the user mobile terminal 70. A signal instructing the HGW80 to restart the HGW80 is transmitted to the HGW80 via the above. Therefore, it is possible to transmit a signal instructing the HGW 80 to restart and instruct the HGW 80 to automatically restart. For example, the HGW 80 itself also has the function of a wireless LAN router in the home, and when the user mobile terminal 70 is a smartphone, it can be realized only by installing a dedicated application on the smartphone.

[Fourth Embodiment]
In the first to third embodiments described above, the case where the restart instruction notification device 10B on the mobile operator side notifies the user mobile terminal 70 and the HGW 80 of the restart instruction of the HGW 80 has been described. It is not limited to. For example, the staff of a care service operator other than the mobile operator who has permission to handle the user information may be notified of the instruction to restart the HGW 80.

Therefore, in the following, the restart instruction notification device 10C according to the fourth embodiment notifies the staff of the care service provider and the like of the restart instruction of the HGW 80, and the staff notifies the user for home-visit care. A case where the restart operation of the HGW 80 is executed when visiting the home will be described. The description of the same configuration and processing as those of the communication system according to the first to third embodiments will be omitted.

FIG. 13 is a diagram illustrating an overall processing flow in the communication system according to the fourth embodiment. As shown in FIG. 13, when the SNMP server 30 detects the restart of the ER20, it notifies the restart instruction notification device 10C of the information of the restarted ER20 (see (1) and (2) of FIG. 13). Then, when the restart instruction notification device 10C receives the information of the restarted ER20 from the SNMP server 30, it acquires the user identification information under the restarted ER20 from the customer information DB 40 and matches the acquired user identification information. Information such as the user's residence is acquired from the notification destination information DB 50 (see (3) and (4) in FIG. 13).

Here, an example of the table stored in the notification destination information DB 50 will be described with reference to FIG. FIG. 14 is a diagram showing an example of a table stored in the notification destination information DB. As illustrated in FIG. 14, for example, the notification destination information DB 50 stores at least "user identification information" and "residential information" indicating a user's home address in association with each other. To explain with reference to the example of FIG. 14, for example, the notification destination information DB 50 stores the user identification information “user A” and the residence information “A-ku, Tokyo” in association with each other. This means that the home address of "User A" is "A-ku, Tokyo".

Then, the restart instruction notification device 10C sends a message instructing the restart of the HGW 80 to the terminal or the like of the staff of the corresponding care service provider 120 based on the acquired information such as the user's residence, and restarts the HGW. Notify that it should be done (see (5) in FIG. 13). For example, the restart instruction notification device 10C transmits the user information, the user's residence information, and the message instructing the restart of the HGW to the terminal of the staff of the care service provider 120. Then, the staff of the care service provider 120 restarts the HGW 80 with the permission of the user at the time of home-visit care (see (6) in FIG. 13).

When the HGW80 is restarted, it performs a process of issuing a series of IP addresses from the transmission of the DHCP Discover to the DHCP server 90 to the reception of the DHCP Ac from the DHCP server 90, and the IP address of the HGW80 is applied to the filter function of the ER20. Is relearned (see (7) in FIG. 13).

As described above, in the restart instruction notification device 10C according to the fourth embodiment, the HGW 80 is re-established for the staff of the care service provider other than the mobile operator who has obtained permission for the handling of user information. Since the start instruction is notified, for example, by sending a notification requesting the restart operation of the HGW 80 to the caregiver who visits the user's home, the communication of the HGW 80 can be restarted without the user himself restarting the HGW 80. It is possible to accelerate.

[System configuration, etc.]

It is also possible to automatically perform all or part of the above by a known method. In addition, the processing procedure, control procedure, specific name, and information including various data and parameters shown in the above document and drawings can be arbitrarily changed unless otherwise specified.

[program]
FIG. 15 is a diagram showing a computer that executes the restart instruction notification program. The computer 1000 has, for example, a memory 1010 and a CPU (Central Processing Unit) 1020. The computer 1000 also has a hard disk drive interface 1030, a disk drive interface 1040, a serial port interface 1050, a video adapter 1060, and a network interface 1070. Each of these parts is connected by a bus 1080.

The memory 1010 includes a ROM (Read Only Memory) 1011 and a RAM 1012. The ROM 1011 stores, for example, a boot program such as a BIOS (Basic Input Output System). The hard disk drive interface 1030 is connected to the hard disk drive 1090. The disk drive interface 1040 is connected to the disk drive 1100. For example, a removable storage medium such as a magnetic disk or an optical disk is inserted into the disk drive 1100. The serial port interface 1050 is connected to, for example, a mouse 1051 and a keyboard 1052. The video adapter 1060 is connected to, for example, the display 1061.

The hard disk drive 1090 stores, for example, the OS 1091, the application program 1092, the program module 1093, and the program data 1094. That is, the program that defines each process of the restart instruction notification device 10 is implemented as a program module 1093 in which a code that can be executed by a computer is described. The program module 1093 is stored in, for example, the hard disk drive 1090. For example, a program module 1093 for executing a process similar to the functional configuration in the device is stored in the hard disk drive 1090. The hard disk drive 1090 may be replaced by an SSD (Solid State Drive).

Further, the data used in the processing of the above-described embodiment is stored as program data 1094 in, for example, a memory 1010 or a hard disk drive 1090. Then, the CPU 1020 reads the program module 1093 and the program data 1094 stored in the memory 1010 and the hard disk drive 1090 into the RAM 1012 and executes them as needed.

The program module 1093 and the program data 1094 are not limited to those stored in the hard disk drive 1090, but may be stored in, for example, a removable storage medium and read by the CPU 1020 via the disk drive 1100 or the like. Alternatively, the program module 1093 and the program data 1094 may be stored in another computer connected via a network or WAN. Then, the program module 1093 and the program data 1094 may be read by the CPU 1020 from another computer via the network interface 1070.
