(Embodiment)
[1. Communication control processing]
First, an example of the communication control process according to the embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of communication control processing according to the embodiment. FIG. 1 shows an example in which processing is performed by the communication control device 1 in the communication system S to control communication performed by users (related user U1 and non-related user U2).

  Here, the communication includes transmission and reception of data with a server apparatus (not shown) that provides various Internet services, and transmission and reception of data performed between user terminals via a predetermined network. Also, the Internet service includes, for example, shopping service, browsing of a website of a home page created by a user or an organization, and the like.

  As shown in FIG. 1, a communication system S according to the embodiment includes a communication control device 1 and user terminals 100-1 and 100-2. The communication control device 1 and the user terminals 100-1 and 100-2 are communicably connected by wire or wireless via a predetermined network N (see FIG. 9) not shown.

  The configuration of the communication system S shown in FIG. 1 is an example, and the present invention is not limited to this. For example, in the communication system S, a server apparatus that provides various Internet services to the communication control apparatus 1 may be connected. Also, in the following, the plurality of user terminals 100-1 and 100-2 may be described as the user terminal 100.

  The user terminals 100-1 and 100-2 are information processing apparatuses used by users (related user U1 and non-related user U2). The user terminal 100 is realized by, for example, a smartphone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, a mobile phone, a PDA (Personal Digital Assistant), or the like.

  Further, in the example shown in FIG. 1, the user terminal 100-1 is used by the related user U1 associated with the disaster area and the user terminal 100-2 is used by the non-related user U2 other than the related user. Indicates Also, in the following, when it is not necessary to distinguish and express in particular, the user terminals 100-1 and 100-2 are described as the user terminal 100, and the related user U1 and the non-related user U2 are described as the user U.

  The communication control device 1 performs processing for controlling communication from the user U to the Internet service, as well as providing Internet services such as a shopping service, an auction service, and a website.

  Here, a conventional communication control device will be described. In the conventional communication control apparatus, for example, when a natural disaster or the like occurs, communication from users other than the disaster area to users in the disaster area is restricted. However, for example, even if the user is a user other than the afflicted area, for example, when the home is a stricken area, there is a risk that communication can not be performed due to the communication restriction even when trying to communicate with the family of the home.

  Therefore, the communication control device 1 according to the embodiment performs communication control processing so that the user U other than the disaster area can also communicate. Specifically, the communication control device 1 first acquires user information which is information related to the user U (step S1). The user information includes, for example, information such as the address of the user U and the address of a home, but the details of the user information will be described later with reference to FIG.

  Subsequently, the communication control device 1 detects the occurrence of a disaster (step S2). The disasters referred to here include natural disasters such as storms, heavy rains, heavy snowfalls, floods, storm surges, earthquakes, tsunamis, and eruptions, and human-made disasters such as traffic accidents such as vehicles, ships, trains and planes.

  Subsequently, when the occurrence of a disaster is detected, the communication control device 1 determines whether or not the user U is a related user U1 associated with a stricken area associated with the disaster based on the user information (step S3). When it is not determined that the user is the related user U1, the user is a non-related user U2.

  The related user U1 is, for example, a user whose present location is a disaster area, a user whose communication access source is a disaster area, a user whose home is in a disaster area, a user who has visited the disaster area in the past, It includes users who have searched information on the afflicted area and have purchased products sold in the afflicted area.

  Subsequently, when the communication control device 1 determines that the user U is the related user U1, the communication control device 1 prioritizes and communicates the related user U1 over the non-related user U2 (step S4). That is, the communication control device 1 makes the communication priority of the related user U1 higher than that of the non-related user U2.

  For example, as control for prioritizing communication, a band used for communication (hereinafter, used band) is divided into two, a first band and a second band, and the first band is a band rather than the second band. Make it wider. And, the communication of the related user U1 uses the first wide band, and the communication of the non related user U2 uses the second narrow band.

  Further, as control for prioritizing communication, the processing order of requests received from the related user U1 and the non-related user U2 may be rearranged so as to preferentially process the requests of the related user U1.

  As described above, by giving priority to the communication of the related user U1 associated with the afflicted area, even the user U other than the afflicted area can perform communication. In addition, for example, by limiting the bandwidth, the communication of the unrelated user U2 can be limited, so that network congestion can be prevented.

As shown in FIG. 3, in the mode information 41, there are two control modes, a normal mode st1 and an emergency mode st2.

  The normal mode st1 is a control mode that allows all users U to communicate equally. The emergency mode st2 is a control mode in which the communication of the related user U1 is prioritized over the non-related user U2.

  Of these two control modes, the communication control unit 35 reads and executes the normal mode st1 during normal operation, and the normal operation is performed when the occurrence of a disaster is detected by the detection unit 33 described later. The mode is switched from the mode st1 to the emergency mode st2.

(3-2-2. User information 42)
The user information 42 is information on the user U who communicates via the network N. FIG. 4 is a diagram showing the user information 42. As shown in FIG. As shown in FIG. 4, the user information 42 includes items such as “user ID”, “user name”, “address”, and “home address”.

  The “user ID” is identification information for identifying the user U. The “user name” is information indicating the name of the user U. The “address” is information indicating the current address of the user U. The “home address” is information indicating the address of the user U's home.

  In the example illustrated in FIG. 4, the user ID “1” indicates that the user name is “AA”, the current address is “FF”, and the address of the parent's house is “FF”. That is, the user “AA” indicates that the current address and the address of the parent's house are the same, and thus live in the parent's house.

  The user ID "2" indicates that the user name is "BB", the current address is "HH", and the address of the parent's house is "GG". That is, the user “BB” indicates that the current address and the address of the parent's house are different, and therefore, does not live in the parent's house.

(3-2-3. Behavior information 43)
The action information 43 is information indicating the action of the user U on the network N. FIG. 5 is a diagram showing the action information 43. As shown in FIG. As shown in FIG. 5, the action information 43 includes items such as “user ID”, “action ID”, “date and time”, “type”, and “content”.

  The “user ID” is identification information for identifying the user U. “Action ID” is identification information for identifying the action of the user U. The "date and time" is information indicating the date and time when the user U acted. "Type" is information indicating the type of action on the network. The “content” is information indicating the content of the action of the user U.

  In the example shown in FIG. 5, the user U of the user ID "1" performs the action of the action ID "AC1" to "2017/8/24", the type is "search", and the query specified in the search is Show that it is "A prefecture sightseeing".

  In addition, user U of user ID “1” performs the action of action ID “AC2” on “2017/8/23”, the type is “browse”, the content of the brow is “HP of A city B city (Homepage) Indicates that it is "browse".

  In addition, user U of user ID “1” performs the action of action ID “AC3” on “2017/8/19”, the type is “purchase”, and the content of the purchase is “purchase from A prefecture melon” To indicate that

  The action information 43 is not limited to the above, and various information may be included according to the purpose. For example, the action information 43 may also include “time” as “date and time”. Further, for example, the action information 43 may include information such as the number of searches for the same query, the number of browsing HP, and the number of purchases of a product.

  Returning to the description of FIG. 2, the control unit 3 is a controller, and is stored in a storage device in the communication control device 1 by, for example, a central processing unit (CPU) or a micro processing unit (MPU). The various programs (corresponding to an example of the communication control program) are implemented by executing the RAM as a work area. The control unit 3 is a controller, and is realized by an integrated circuit such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA).

  As shown in FIG. 2, the control unit 3 includes an acquisition unit 31, a reception unit 32, a detection unit 33, a determination unit 34, and a communication control unit 35, and functions of communication control processing described below. Realize or perform the action.

(3-3. Acquisition unit 31)
The acquisition unit 31 acquires various information. For example, the acquisition unit 31 acquires user information 42 which is information on the user U who communicates via the network N. For example, the acquisition unit 31 acquires the user information 42 by an input operation on the user terminal 100 of the user U.

  In addition, the acquisition unit 31 further acquires SNS information on the network constructed by the user U in social networking. The SNS information includes, for example, information (current position, past position history, and the like) regarding other users connected to the network constructed by the user U.

(3-4. Reception unit 32)
The receiving unit 32 receives various information. For example, the reception unit 32 receives a request of the user U in communication. The request referred to here is a search request including a search query such as a website search or a product search for a shopping site, or information on purchase of a product (for example, payment method, delivery destination, number of products, etc.) at the shopping site. Includes purchase requests.

(3-5. Detection unit 33)
The detection unit 33 detects the occurrence of a disaster. For example, the detection unit 33 may use natural disasters such as storms, heavy rains, heavy snowfalls, floods, high tides, earthquakes, tsunamis, and eruptions as human disasters and human-made disasters such as traffic accidents such as vehicles, ships, trains, and planes. To detect.

  Specifically, the detection unit 33 detects the occurrence of a disaster by receiving an emergency signal (for example, a signal indicating an early earthquake early warning) emitted by an organization such as the Japan Meteorological Agency. In addition, the detection unit 33 is, for example, a disaster based on a shake (such as a shake caused by an earthquake or an eruption) occurring around the user U based on values of a gyro sensor or the like mounted on the user terminal 100 of the user U. To detect the occurrence of

  Moreover, the detection part 33 may detect by receiving generation | occurrence | production of a disaster by input operation to the user terminal 100 of the user U. FIG. Further, in the case of a disaster that moves like, for example, a typhoon, the detection unit 33 may identify the occurrence of the disaster and the stricken area based on the information indicating the predicted course of the typhoon.

  In addition, the detection unit 33 detects the magnitude of the disaster. For example, the detection unit 33 detects information such as the seismic intensity of an earthquake, the maximum instantaneous wind speed of a typhoon, the amount of precipitation, the height of waves, and the like as the scale of disaster based on disaster information transmitted from the Japan Meteorological Agency.

(3-6. Determination unit 34)
When the occurrence of a disaster is detected by the detection unit 33, the determination unit 34 determines, based on the user information 42 acquired by the acquisition unit 31, whether or not the user U is the related user U1 associated with the disaster area associated with the disaster. judge.

  For example, when the access source in the communication of the user U is the disaster area, the determination unit 34 determines that the user U is the related user U1. The access source can be identified, for example, by referring to the access source IP address. On the other hand, when the access source in the communication of the user U is not a disaster area, the determination unit 34 determines that the user U is a non-related user U2 other than the related user U1.

  Further, when the address of the user U's home is the disaster area, the determination unit 34 determines that the user U is the related user U1. In the determination unit 34, the current address of the user U may be the same as or different from the address of the parent's house.

  On the other hand, when the home address of the user U is not a disaster area, the determination unit 34 determines that the user U is not the related user U1, that is, determines that the user U is the non-related user U2. The determination unit 34 determines that the related user U1 is the related user U1 if the current address of the user U is a disaster area, even if the address of the parent's house is not a disaster area.

  Further, based on the action information 43 acquired by the acquisition unit 31, the determination unit 34 determines that the user U is the related user U1 when the user U performs an action related to the disaster area. Specifically, when the user U searches for information related to a disaster area before the occurrence of a disaster, the determination unit 34 determines that the user U is a related user U1. The information on the afflicted area includes, for example, information on a touristic area in the afflicted area, a residence of the afflicted area (e.g., rental and sale of houses), and a company in the afflicted area.

  In addition, the determination unit 34 may determine that the related user U1 is not limited to simply searching, and may be the case of purchasing a product, browsing a website, or the like. For example, if the determination unit 34 has purchased the related product (for example, fruits and the like from the afflicted area) of the afflicted area through the network based on the action information 43, the user U is related before the occurrence of the disaster. It is determined that the user U1.

  Further, the determination unit 34 determines that the user U is the related user U1, for example, when the user U has visited the afflicted area once or a plurality of times in the past based on the schedule information on the schedule of the user U. You may Further, the determination unit 34 may determine whether or not the disaster area has been visited based on history information of the position of the user U, not limited to the schedule information.

  The schedule information is, for example, information on a schedule registered by the user U in the user terminal 100, and includes a schedule scheduled to be performed in the future and a schedule performed in the past. Further, the schedule information may include not only the place visited, but also the action performed at the place visited.

  Further, for example, when the user U plans to visit the disaster area based on the above-described schedule information, the determination unit 34 may determine the user U as the related user U1. Further, the determination unit 34 may estimate the schedule of the user U by analyzing not only the schedule information but also the sentences of the mail of the user U and the like.

  In addition, the determination unit 34 determines that the user U is the related user U1, for example, when the current location of another user connected to the network constructed by the user U based on the SNS information acquired by the acquisition unit 31 is a disaster area judge.

(3-7. Communication control unit 35)
When the determination unit 34 determines that the user is the related user U1, the communication control unit 35 prioritizes and communicates the related user U1 over the non-related user U2. The communication control unit 35 controls communication by band control, for example. This point will be described with reference to FIG.

  FIG. 6 is a diagram showing processing contents of the communication control unit 35. As shown in FIG. In FIG. 6, the bandwidth of the used band in communication is indicated by an index value of "100". Note that the communication speed is faster as the index value is larger. In FIG. 6, it is assumed that the communication control unit 35 performs communication of all users using the use band “100” at normal times other than the time of disaster.

  As shown in FIG. 6, on the first day when a disaster occurs, the communication control unit 35 uses a first band having a first bandwidth "80" and a second band narrower than the first bandwidth. Divide into a second band having a width "20". Then, the communication control unit 35 assigns the related user U1 to the first band, and assigns the non-related user U2 to the second band.

  Subsequently, on the second day when a disaster occurs, the communication control unit 35 uses the first band having the first band width “70” and the second band width “the second band width narrower than the first band”. Change to the second band having “30”. Then, the communication control unit 35 assigns the related user U1 to the first band, and assigns the non-related user U2 to the second band. That is, the communication control unit 35 narrows the bandwidth of the first band and extends the bandwidth of the second band as time passes from the occurrence of a disaster.

  Then, after the predetermined period has elapsed, the communication control unit 35 cancels the state of being divided into the first band and the second band, and returns it to the normal use band “100”. In addition, you may set the recovery period of the disaster analyzed based on the past disaster case, for example as a predetermined period.

  Further, the communication control unit 35 is not limited to the communication control based on the band control shown in FIG. 6, and may perform communication control based on priority control, for example. Specifically, when the receiving unit 32 receives a request from the related user U1 and the non-related user U2, the communication control unit 35 prioritizes and communicates the request of the related user U1.

  The communication control unit 35 may perform communication control by, for example, scoring the degree of association with the afflicted area based on the user information 42. For example, the communication control unit 35 sets the affinity score indicating the degree of association with the afflicted area to S, sets the affinity score between the related user U1 at the moment of occurrence of the disaster to the afflicted area to Sa, and the past related user U1. When the affinity to the disaster area is Sb, m is itself, m is another user, predetermined weighting parameters are α, β, and γ, and the relationship between m and u is d (m−u). Sex scores S, Sa and Sb are as follows.

  That is, S = Sa + γSb. Further, Sa = Sam + αα [d (m−u)] · Sau. Further, Sb = Sbm + βΣ [d (m−u)] · Sbu. In addition, as an example of an element of Sa, for example, there is an IP address, position information and the like. Further, examples of elements of Sb include the number of visits to the afflicted area in the past, the number of times (or the amount of money) the related product has been purchased, and the number of searches for the afflicted area.

  Note that the calculation method of the affinity score S is an example, and any calculation method may be used as long as it indicates the degree of association between the related user U1 and the disaster area. That is, the affinity score S may or may not be based on the user information 42.

  Further, at the time of bandwidth control, the communication control unit 35 changes the threshold for giving priority to the communication of the affinity score S in accordance with the basic performance (so-called spec) of the request acceptance server (for example, a server providing a web page). It is also good. For example, in the case of a server having a relatively low basic performance, for example, prioritizing the communication of the related user U1 of the top 5% of the affinity score, and in the case of a server having a relatively high basic performance, for example, the top 70% Communicate with

[3. Processing procedure]
Next, the procedure of the process performed by the communication control device 1 according to the embodiment will be described with reference to FIG. FIG. 7 is a flowchart showing the procedure of the communication control process performed by the communication control device 1 according to the embodiment.

  As shown in FIG. 7, first, the detection unit 33 detects the occurrence of a disaster (step S101). Subsequently, the acquisition unit 31 acquires user information 42 which is information on the user U who communicates via the network N (step S102).

  Subsequently, the receiving unit 32 determines whether a request for the user U in communication has been received (step S103). When the receiving unit 32 receives the request (Yes at Step S103), the determining unit 34 determines whether the user U is the user U associated with the disaster area associated with the disaster based on the user information 42 acquired by the acquiring unit 31. It is determined (step S104).

  Subsequently, when the determination unit 34 determines that the user is the related user U1 (Yes in step S104), the communication control unit 35 assigns the communication of the related user U1 to the first band (step S105), and ends the process. .

  On the other hand, in step S103, when the receiving unit 32 does not receive the request of the user U (step S103, No), the processing ends.

  In step S104, when the communication control unit 35 determines that the user U is not the related user U1, that is, the non-related user U2 by the determination unit 34 (step S104, No), communication of the non-related user U2 is performed. Allocating to the second band (step S106), the process ends.

[4. Modified example]
In the embodiment described above, the communication control unit 35 divides the use band into two bands of the first band and the second band, but may divide it into three or more bands. This point will be described with reference to FIG.

  FIG. 8 is a diagram showing processing contents of the communication control unit 35 according to the modification. As shown in FIG. 8, the communication control unit 35 may further divide the first band into two. As shown in FIG. 8, for example, the communication control unit 35 sets the bandwidth "80" of the first band to the bandwidth "50" of the first band used for the communication of the first related user and the second related user And the bandwidth "30" of the first band used for the communication of

  The first related user and the second related user may be set, for example, in order of proximity to the center of the disaster area. That is, since it is assumed that the damage is greater as the center of the afflicted area is closer, the first related user near the center of the afflicted area is allocated to the first band of the widest bandwidth “50”.

  In this way, it is possible to give top priority to the communication of the first related user who really needs to communicate among the afflicted areas.

[5. effect〕
As described above, the communication control device 1 according to the embodiment includes the detection unit 33 and the communication control unit 35. The detection unit 33 detects the occurrence of a disaster. When the occurrence of a disaster is detected by the detection unit 33, the communication control unit 35 gives priority to the communication of the related user U1 who is the user U related to the stricken area due to the disaster over the non-related user U2 other than the related user U1. .

  Thus, communication can be performed even for users other than the disaster area (for example, related user U1) while preventing congestion of the network.

  Furthermore, in the communication control device 1 according to the embodiment, the communication control unit 35 has a first band having a first bandwidth and a second band narrower than the first band, which is used in communication. The second band is divided, the related user U1 is allocated to the first band, and the non-related user U2 other than the related user U1 is allocated to the second band.

  As a result, since the related user U1 can use the first band having a wide bandwidth, communication can be performed without lowering the communication speed.

  The communication control device 1 according to the embodiment further includes a receiving unit 32. The receiving unit 32 receives a request of the user U in communication. When the reception unit 32 receives a request from both the related user U1 and the non-related user U2, the communication control unit 35 prioritizes and communicates the request of the related user U1.

  Thereby, since the request in the communication of the related user U1 can be processed with priority, the content corresponding to the request can be transmitted to the related user U1 with priority.

  Further, in the communication control device 1 according to the embodiment, when the access source in the communication of the user U is a disaster area, the determination unit 34 determines that the user U is the related user U1.

  Thereby, the communication of the related user U1 who has accessed from the disaster area can be prioritized.

  In the communication control unit 35 according to the embodiment, when the home of the user U is a disaster area, the determining unit 34 determines that the user U is the related user U1.

  As a result, for example, even if the related user U1 is away from the home, it is possible to prioritize the confirmation of the home's condition (such as safety or the like) even if the home is affected.

  Further, in the communication control device 1 according to the embodiment, when the user U has visited the disaster area in the past, the determination unit 34 determines that the user U is the related user U1.

  Thereby, for example, when the related user U1 has visited the affected area in the past and is enthusiastic, it is possible to quickly confirm the situation of the affected area or the like.

  Further, in the communication control device 1 according to the embodiment, when the user U plans to visit the disaster area, the determination unit 34 determines that the user U is the related user U1.

  Thereby, for example, since the related user U1 can quickly confirm the situation of the afflicted area, it can be easily determined whether or not the afflicted area can be visited as scheduled.

  In addition, in the communication control device 1 according to the embodiment, the acquisition unit 31 further acquires SNS information on the network constructed by the user U in social networking. The determination unit 34 determines that the user is the related user U1 when the current position of the other user connected to the network constructed by the user U is the disaster area based on the SNS information.

  This allows you to quickly confirm the status of friends connected to SNS.

  In addition, in the communication control device 1 according to the embodiment, the acquisition unit 31 further acquires behavior information indicating the behavior of the user U on the network before the occurrence of a disaster. The determination unit 34 determines that the user U is the related user U1 when the user U performs an action related to the disaster area based on the action information.

  As a result, communication can be preferentially performed to the related user U1 who has accessed information on the disaster area on the network.

  In addition, in the communication control device 1 according to the embodiment, the determination unit 34 determines that the user U is the related user U1 when the user U searches for information related to a disaster area before the occurrence of a disaster.
