Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
FIG. 2 shows an apparatus for diagnosing the state of a wireless communication service according to the first embodiment of the invention. The device 200 is a device for diagnosing the state of communication services provided by a business operator having a communication infrastructure 220 connected to a communication infrastructure 210 of an MNO. Communication is performed on an IP network such as. In addition, the device 200 communicates with a user terminal 230 used by a user associated with one or more SIMs to be diagnosed over an IP network such as the Internet in order to view the diagnosis results. In FIG. 2, one IoT device 240 having a SIM associated with the user is shown as an example.

In FIG. 2, the communication infrastructure 220 is shown as the communication infrastructure of the MVNO, but it may be the communication infrastructure of the MVNE, or any communication infrastructure that is connected to the communication infrastructure 210 of the MNO. Although the communication infrastructure 220 may be referred to as the communication infrastructure of the MVNO below, it should be added that this does not mean that the communication infrastructure 220 is limited to that of the MVNO only.

The device 200 includes a communication unit 201 such as a communication interface, a processing unit 202 such as a processor and a CPU, and a storage unit 203 including a storage device or storage medium such as a memory or hard disk. It can be configured by running Device 200 may include one or more devices, computers or servers. Also, the program may include one or more programs, and may be recorded on a computer-readable storage medium to be a non-transitory program product. The program can be stored in a storage device or storage medium such as the database 204 accessible from the storage unit 203 or the device 200 via the IP network, and can be executed by the processing unit 202 . Data described below as being stored in storage 203 may be stored in database 204, and vice versa. Device 200 may be one or more instances on the cloud.

Here, in this specification, the term "cloud" refers to a system that can dynamically provision and provide computing resources such as CPU, memory, storage, and network bandwidth on a network according to demand. For example, a cloud can be used by AWS or the like. In this specification, the term "public cloud" refers to a cloud that can be used by multiple tenants.

The communication infrastructure 220 includes a gateway that communicates with the communication infrastructure 210 of the MNO using the GTP protocol, and one or more facilities for operating the gateway to operate the wireless communication service and storing its history. Each of these can be one or more instances on the cloud or public cloud, and communication infrastructure 220 has multiple instances on the cloud or public cloud.

The MVNO communication infrastructure 220 stores a history of wireless communication services used by the IoT device 240 using its SIM. For example, session creation time, session deletion time, device identifier such as IMEI, etc. are stored in association with the SIM identifier. Alternatively, the interval from the creation time of the session to the deletion time may be calculated as the duration of the session and stored in association with the SIM identifier. Below, the information about the session for each SIM is also referred to as "session information". Session information can include information about one or more session events, examples of which include session creation, deletion, and the like.

In the MVNO communication infrastructure 220, communication occurrence time, communication volume, etc. are stored in association with the SIM identifier. Hereinafter, information related to communication after connection for each SIM is also referred to as "communication information", and may partially overlap with session information.

In addition, the MVNO communication infrastructure 220 includes SIMs such as ready, active, inactive, standby, suspended, and terminated. usage status can be stored in association with the SIM identifier. The usage status of the SIM may also include a device restriction setting that limits devices that can use the SIM to devices identified by a predetermined device identifier. This is the so-called IMEI lock.

In the communication infrastructure 210 of the MNO, for example, contract details such as SIM communication quality issued by the MNO or a contract plan representing the contract details are stored in association with the SIM identifier. Also, SIM location information may be stored in the MNO's communication infrastructure 210 in association with the SIM identifier. Information that indirectly indicates the location of the SIM, such as an identifier that identifies the base station to which it is connected, can be used as the location information. At least one of cell ID such as area code, CID, ECID, etc. is included. When a subscriber management database such as HLR/HSS is included in the communication infrastructure 220, it is possible for a business operator having the communication infrastructure 220 to issue a SIM. The data described as being stored in is stored in the MVNO's communication infrastructure 220 . In the following, the information about the SIM is also referred to as "SIM information", including the SIM usage status, contract details, location information, and the like.

The IoT device 240 may store SIM location information in addition to the SIM identifier. The location information can be the same information as at least part of the SIM location information stored in the MNO communication infrastructure 210 or the MVNO communication infrastructure 220 described above. In addition, the IoT device 240 may store a device identifier, remaining battery level, radio wave intensity, base station identifier for identifying a connectable base station, or the like, or acquire such information upon request. may be memorized. Information related to IoT devices that use SIMs and that does not depend on the relevant SIMs is hereinafter also referred to as "IoT device information". Here, "radio wave intensity" represents the strength of radio waves received by an antenna of a device such as RSSI from a base station. The "base station identifier" includes, for example, a country code such as MCC that identifies one or more connectable base stations, a network code such as MNC, an area code such as LAC and TAC, and CID and ECID. A combination of one or more cell IDs such as

FIG. 3 shows the flow of a method for diagnosing the state of wireless communication service according to the first embodiment of the present invention. First, the device 200 receives a diagnosis request for at least one of the one or a plurality of SIMs from the user terminal 230 of the user who uses the one or a plurality of SIMs provided by the business operator having the communication infrastructure 220. (S301). The diagnosis request, in one example, includes one or more SIM identifiers identifying one or more SIMs to be diagnosed and a diagnosis period. When the specific SIM identifier is not included, the device 200 may determine one or more SIMs associated with the user to be diagnosed. Similarly, even when the specific diagnostic period is not included , the device 200 may determine some diagnostic period.

FIG. 4 shows an example of an input screen for diagnostic request information according to the first embodiment of the present invention. The ICCID "89811000055804625842" is entered as the SIM identifier, and the diagnosis period is from 12:00 on May 3, 2021 to 12:00 on May 9, 2021.

The device 200 transmits to the user terminal 230 an acceptance notification notifying that the diagnosis request has been accepted (S302). Depending on the content of the diagnosis, it may take 10 seconds or more to complete the diagnosis, so it is preferable to notify the user that the diagnosis request has been received. , it is conceivable to directly return display information for displaying the diagnosis result as described later. Although the above diagnostic request was not described, various diagnostics are possible as described later, and the diagnostic content may be included in the diagnostic request. When a problem occurs that desired communication cannot be performed, the waiting time can be shortened by allowing the user to specify necessary diagnostic content. The acceptance notification is sent by communication on the IP network, and more specifically, it can be sent as an HTTP response as a response to the HTTP request from the user terminal 230 .

Next, in response to the diagnosis request, the device 200 requests one or more instances included in the communication infrastructure 220 to obtain state information regarding the state of the wireless communication service related to one or more SIMs to be diagnosed. Send (S303). As an example, the acquisition request may be directly or indirectly transmitted from the device 200 to each instance. The acquisition request is sent by communication over an IP network, and more specifically can be sent as an HTTP request.

Each instance that has received the acquisition request acquires predetermined state information for one or more SIMs to be diagnosed (S304) and transmits it to the device 200 (S305). State information includes session information, communication information, SIM information, and the like. If the state information is already stored, the instance that received the acquisition request can promptly transmit the state information to the device 200 . It may take several seconds to several tens of seconds to obtain the latest IoT device information such as radio wave intensity and base station identifiers that can be requested and acquired. Such requests to the IoT device 240 can use, for example, AT commands for modem control.

Depending on the type of status information, status information may not be acquired for the specified diagnosis period. In such a case, the instance that received the acquisition request may acquire information outside the diagnosis period, such as current information, for the type of state information.

The operation information of the wireless communication service provided using the communication infrastructure 220 may be stored by equipment included in the communication infrastructure 220 so that it can be obtained as status information. It is preferable to store the information in a server (not shown) outside the communication infrastructure 220 in order to be able to provide the information to the user. The device 200 may obtain operating information of the wireless communication service from such a server as status information.

The device 200 performs diagnostic processing based on the received status information (S306). As an example, the diagnosis process may detect, as a problem related to the usage status, that there was a period during which the SIM usage status was in a situation other than a predetermined status within the diagnosis period. Another example is the detection of problems with connection or communication status during diagnostics. More specifically, the problem of connection status is that sessions are not created or deleted more than a predetermined number of times within the diagnosis period, and sessions that deviate from the average value of the session duration distribution within the diagnosis period by more than a predetermined value. exist. The value of the predetermined number of times can be determined for each session event, and can be set to once for each session event, for example. The predetermined value may be the standard deviation of the distribution or a value obtained by multiplying it by a constant. Also, the distribution of session durations is not limited to sessions in the diagnosis period, and may be based on sessions within a predetermined period using SIMs to be diagnosed. For example, if the session duration is short, it means that the session was created and deleted repeatedly, which makes it possible to guess that the radio wave condition was bad during that period. In addition to session information, it is conceivable to use at least part of IoT device information such as radio wave intensity to perform diagnostic processing. Problems related to the communication status include, more specifically, data communication not exceeding a predetermined value within a specified period, communication volume exceeding a predetermined value, and the like.

Here, it is described that the presence or absence of problems related to the usage status, the connection status, and the communication status is diagnosed, but the presence or absence of problems related to other situations may be diagnosed. Diagnosis for each situation can be performed by storing diagnostic criteria in the storage unit 203 and referring to the diagnostic criteria based on the acquired state information. The diagnostic criteria can be code that defines a diagnostic algorithm, and includes, for example, code generated by machine learning.

For example, if it is determined that there is a problem with the wireless communication service and there is a problem with the operational status based on the operational information, other conditions will be reported at the time or time period when the problem occurred. Even if it is determined that there is a problem, it is possible to highlight the existence of the problem regarding the operating status and display it. Displaying only problems related to the operating status is also an example of highlighting problems related to the operating status. More generally, diagnostic processing can be performed based on at least one of state information and operating information.

As another example, based on the location information, it is determined that there is a possibility of theft and there is a problem with the location status if the location of the SIM is separated by a predetermined distance or more within a predetermined period of time. be able to. Further, regarding the possibility of theft, it is also possible to determine whether or not the IoT device 240 is a pre-approved device based on the device restriction setting of the SIM.

Then, the device 200 transmits the display information of the diagnosis result display screen based on the state information to the user terminal 230 (S307). FIG. 5 shows an example of a diagnostic result display screen according to the first embodiment of the present invention. In the user terminal 230, the diagnosis result display screen 500 is displayed on the web browser, and the display information may be data in HTML format. In this example, a SIM usage overview 510, a connection status overview 520, and a communication status overview 530 are displayed on the diagnosis result display screen 500 as the diagnosis results. As shown in the figure, by arranging and displaying these conditions on a straight line, you can easily understand where the problem is, and display a summary of the SIM usage status, connection status, and communication status diagnosis results. Although shown in FIG. 5 as an example, a list of diagnosis results or an outline thereof may be displayed for at least two or more situations among a plurality of situations included in the diagnosis results.

The usage status overview 510 is based on the SIM information included in the status information, and in the illustrated example, the overview shows that no particular problem was detected during the diagnosis period and that the current status is in use. there is

FIG. 6 is an example of a diagnostic result display screen when the current usage status is inactive. By displaying each situation in different visual representations such as different colors in accordance with the result of diagnostic processing, it is possible to make it easier to understand where the problem is. This example shows that there is a problem with the current usage, but if no problems were detected during the diagnostic period, you could ignore the current usage and just say that no problems were detected. Conceivable.

When the user selects by clicking or tapping the connection status overview 520 displayed on the user terminal 230, as shown in FIG. 7, the connection status details 700 based on the session information can be displayed. Here, on May 26, an IoT device whose device identifier IMEI is "351855000111122" creates and deletes a session in which an LTE connection is made with an MNO represented by "Operator 1", and then on June 14 A state is shown in which a new session is created after creating and deleting a session for 3G connection with an MNO represented by "Operator 2". Some of the various numbers describe values that differ from the actual numbers. In the example of FIG. 7, no particular problem is detected in the connection status, but if a problem is detected, session events related to the problem may be displayed in different visual representations such as different colors. The connection status summary 520 of FIG. 5 may indicate that the problem has been detected. FIG. 8 is an example of displaying in the connection status summary 520 that a connection status problem was detected due to the absence of session creation and deletion within the diagnostic period.

When the user selects by clicking or tapping the communication status overview 530 displayed on the user terminal 230, as shown in FIG. 9, the communication status details 900 based on the communication information can be displayed. In the example of FIG. 9, no particular problem is detected in the communication status, but if a problem is detected, the time or time slot related to the problem or the traffic volume at that time or time slot can be displayed using different visuals such as different colors. It may be indicated by an expression. The detection of the problem may be displayed in the communication status summary 530 of FIG.

As shown in FIGS. 6 and 8, reference information for solving problems may be displayed. Reference information may include links to web pages that describe content related to the issue. In addition, cause information related to settings or logs that may be the cause when a problem occurs may be displayed.

As described above, in one example of the present embodiment, regarding the state of the communication service provided by the operator having the communication infrastructure on the cloud connected to the communication infrastructure of the MNO, the state information regarding the state is acquired and the diagnostic processing is performed. , SIM usage status, connection status, communication status, etc. Diagnosis results or summaries for each situation are displayed in a list on the terminal used by the user for at least two or more situations, so that the status of the communication service is displayed to the user. can be visualized by

Although an example of displaying the outline and details of the diagnosis result of each situation on separate screens has been described, these may be displayed on the same screen. In addition, when the detail screen and the overview screen are separated, a tab for displaying the detail screen of each situation is provided on the overview screen, and when the tab is clicked or tapped, the A detailed screen may be displayed.

Further, in the above description, the device 200 executes diagnostic processing in response to receiving a diagnostic request. If a problem is detected during execution, notification may be made without a request for diagnosis from the user.

In the above description, the diagnostic result is displayed as the diagnostic result display screen 500 on the web browser of the user terminal 230. However, it is not limited to the HTML format, and the PDF format, the image format, and other browsable files. format display information may be generated. The generated display information is transmitted by the device 200 to the user terminal 230 after generation, or is stored in the storage unit 203 of the device 200 after generation, and is downloaded in response to a download request from the user terminal 230. may be sent as
