Description

  The present invention relates to a communication control device, a communication setting method, a communication setting program, and a communication system for controlling communication by a communication device.

  In recent years, vehicles that can communicate by providing a communication device have been sold. A vehicle may be manufactured in one country and then transported to a different country for sale. In this case, a profile (communication profile) is set in the communication device provided in the vehicle so that communication is possible using a communication service provided by a carrier in the destination country. Setting processing for remotely providing a profile to a communication device and enabling it is called remote provisioning.

  In Patent Documents 1 and 2, when a terminal moves from a region where a certain provider provides a communication service to a region where a different provider provides the communication service, a new one corresponding to the destination operator with respect to the terminal is disclosed. A technique for remotely setting a simple profile is described.

US Patent No. 9585000 Specification US Patent Application Publication No. 2016/0192312

  By the way, it is known that it takes several minutes to 10 minutes to remotely set a profile for a communication device. The vehicle may be turned on when it reaches the destination country, turned off again before the profile setting is completed, and stored in a place where communication is impossible, such as underground.

  The techniques described in Patent Documents 1 and 2 do not assume that profile setting is interrupted for a long period of time.

(First embodiment)
[Outline of Communication System S]
FIG. 1 is a schematic diagram of a communication system S according to the present embodiment. The communication system S includes a communication control device 100, a vehicle V, and a base station B. The number of vehicles V and base stations B included in the communication system S is not limited. The communication system S may include devices such as other servers and terminals.

  The base station B is a radio base station apparatus capable of performing radio communication (mobile communication) such as LTE (Long Term Evolution). The base station B includes equipment necessary for wireless communication, such as an antenna, a processor, and an electric circuit, and is wirelessly connected to a communication device within a range (that is, a cell) in which the base station B can communicate. The base station B relays communication between the communication device and the network N such as the Internet.

  The vehicle V is a vehicle such as an automobile, a motorcycle, or a self-propelled construction machine. The vehicle V includes a communication device, and is configured to be able to wirelessly communicate with the network N via the base station B. The vehicle V can receive various information services by communicating with the network N.

  The communication control device 100 is a computer that controls communication of the vehicle V. The communication control device 100 can set a profile for the communication device of the vehicle V via the network N (that is, remote provisioning). The communication control apparatus 100 is connected to the network N by wire or wireless. In FIG. 1, the communication control device 100 is described as one device, but may be configured by a plurality of devices.

  FIG. 2 is a schematic diagram of profile setting performed by the communication control device 100 for the communication device 10 of the vehicle V. The vehicle V includes a communication device 10 for performing communication. The communication device 10 includes equipment necessary for wireless communication, such as an antenna, a processor, and an electric circuit. Furthermore, the communication device 10 includes an eSIM 11 (Embedded Subscriber Identity Module). The eSIM 11 is a storage medium that stores at least one profile. The eSIM 11 may be fixed to the communication device 10 or may be detachably provided.

  A profile is information (data) necessary for communication using a communication service provided by a provider. For example, the profile includes an IMSI (International Mobile Subscriber Identity), and the IMSI includes an MCC (Mobile Country Code) that is region identification information for identifying a region (country or the like) in which a communication service is provided. The MCC is a three-digit number assigned to each region. The eSIM 11 may store the profile in advance, or may receive and store the profile from the communication control apparatus 100 via the network N.

  Further, the eSIM 11 stores a valid or invalid state for each profile stored therein. Each profile stored in the eSIM 11 is validated or invalidated by the communication control device 100 via the network N (that is, remotely). The communication device 10 performs communication based on the profile validated in the eSIM 11. When the communication control device 100 validates a profile stored in advance in the eSIM 11 or when the communication control device 100 sends a profile to the eSIM 11 and validates it is called profile setting.

  When an operator with a vehicle V moves from an area where a communication service is provided to an area where a different operator provides a communication service, the communication device 10 of the vehicle V makes a profile setting request to the communication control device 100. Upon receiving a profile setting request from the communication device 10, the communication control device 100 remotely sets a profile for the communication device 10 (eSIM 11). When the profile setting is completed, the communication device 10 can perform communication in the area after movement.

  In order to remotely set a profile for the communication device 10, it takes about several to ten minutes. If the vehicle V moves to a place where communication is impossible, such as underground, before the profile setting is completed, the profile setting is interrupted. Since the vehicle V may be stored in a place where communication is not possible for a long time (for example, several months or more), if the profile setting is retried infinitely, waste of communication cost and management cost increases. Further, if the number of retries for profile setting is limited, the profile setting cannot be resumed even if the vehicle V becomes communicable after the number of retries expires.

  On the other hand, the communication control apparatus 100 according to the present embodiment can resume the profile setting even when the profile setting is interrupted for a long time by performing the communication setting method described later.

[Configuration of Communication Control Device 100]
FIG. 3 is a block diagram of the communication control apparatus 100 according to the present embodiment. In FIG. 3, arrows indicate main data flows, and there may be data flows not shown in FIG. In FIG. 3, each block shows a functional unit configuration, not a hardware (device) unit configuration. Therefore, the blocks shown in FIG. 3 may be implemented in a single device, or may be separately implemented in a plurality of devices. Data exchange between the blocks may be performed via any means such as a data bus, a network, a portable storage medium, or the like.

  The communication control apparatus 100 includes a control unit 110, a communication unit 120, and a storage unit 130. The control unit 110 includes a reception unit 111, a trigger setting unit 112, and a profile setting unit 113. The communication control apparatus 100 according to the present embodiment is not limited to the specific configuration illustrated in FIG.

  The communication unit 120 is a communication interface for communicating with the communication device 10 of the vehicle V via the base station B. The communication unit 120 includes an antenna, a processor, an electric circuit, and the like for performing wireless communication. The communication unit 120 performs predetermined processing on a communication signal received from the outside to acquire data, and inputs the acquired data to the control unit 110. In addition, the communication unit 120 performs predetermined processing on the data input from the control unit 110 to generate a communication signal, and transmits the generated communication signal to the outside.

  The storage unit 130 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive, and the like. The storage unit 130 stores a program executed by the control unit 110 in advance. In addition, the storage unit 130 stores trigger information indicating conditions for setting a profile for the communication device 10 and profile information indicating a profile to be set for the communication device 10.

  The control unit 110 is a processor such as a CPU (Central Processing Unit), for example, and functions as the reception unit 111, the trigger setting unit 112, and the profile setting unit 113 by executing a program stored in the storage unit 130. The functions of the receiving unit 111, the trigger setting unit 112, and the profile setting unit 113 will be described later. At least a part of the function of the control unit 110 may be executed by an electric circuit. Further, at least part of the functions of the control unit 110 may be executed by a program executed via a network.

[Description of communication setting method]
FIG. 4 is a schematic diagram of a communication setting method executed by the communication control apparatus 100 according to the present embodiment. FIG. 4 shows a situation where a vehicle V that can communicate in the first region (for example, the first country) moves to a second region (for example, the second country) different from the first region. In the first region, profile setting is performed in advance on the eSIM 11 of the vehicle V by remote provisioning or directly (for example, by contacting a terminal for profile setting).

  In a state where the power of the vehicle V is turned on in the first area, the communication device 10 of the vehicle V obtains SIM identification information for identifying the eSIM 11, area identification information for the first area, and a communication operator for the first area The included device information is transmitted to the communication control device 100 via the base station B in the first region (that is, the region before movement) (a). Thereafter, the power supply of the vehicle V is turned off. The receiving unit 111 of the communication control device 100 receives device information transmitted from the communication device 10 of the vehicle V.

  The trigger setting unit 112 (condition setting unit) of the communication control device 100 stores trigger information indicating a trigger (condition) for performing profile setting in the storage unit 130 based on the device information received from the vehicle V. Then, a profile setting trigger is set (b).

  For example, the trigger information includes SIM identification information for identifying the eSIM 11 and area identification information (MCC) corresponding to the profile used in the destination area (second area here). The trigger information may be input to the communication control device 100 by an administrator, or may be automatically determined according to a predetermined rule based on the device information. Further, the trigger setting unit 112 associates profile information indicating a profile to be set when the trigger is satisfied on the storage unit 130 with the trigger information.

  After the trigger setting unit 112 sets a trigger, the vehicle V moves from the first region to the second region by being transported by, for example, a ship or the like with the power turned off (c). When the power source of the vehicle V is turned on in the second region (that is, the vehicle V is energized), the communication device 10 of the vehicle V issues an attach request to the communication control device 100 via the base station B in the second region. Transmit (d). The attach request is a signal for the communication device 10 to start communication, SIM identification information for identifying the eSIM 11, and region identification information (MCC) corresponding to the region (second region here) where communication is to be started. Including. The transmission of the attach request from the communication device 10 to the base station B in the second area is performed outside the service area of the contracting business operator (here, the business operator in the first region) due to the partnership between the business operators. This is performed by a service (roaming or the like) that enables communication if it is within the service area of the partner business operator (the business operator in the second region in this case).

  In the communication control apparatus 100, the profile setting unit 113 determines whether or not the attach request received from the vehicle V satisfies the trigger stored in the storage unit 130 (e). Specifically, the profile setting unit 113 triggers a trigger when the SIM identification information and the region identification information indicated by the trigger information stored in the storage unit 130 match the SIM identification information and the region identification information indicated by the attach request. It is determined that it satisfies. Otherwise, the profile setting unit 113 determines that the trigger is not satisfied. The trigger determination method shown here is merely an example, and other methods that can determine whether or not the profile setting is necessary using a trigger based on an area in which the vehicle V communicates may be used.

  When the attach request does not satisfy the trigger, the profile setting unit 113 does not perform profile setting, and the trigger setting unit 112 maintains the trigger stored in the storage unit 130. When the attach request satisfies the trigger, the trigger setting unit 112 invalidates the trigger stored in the storage unit 130 (f). At this time, the trigger setting unit 112 may invalidate the trigger by setting an invalidation flag in the trigger information stored in the storage unit 130, and the trigger setting unit 112 deletes the trigger information stored in the storage unit 130. It may be invalidated.

  Then, the profile setting unit 113 starts profile setting after the trigger is invalidated (g). The profile setting unit 113 remotely sets a profile for the communication device 10 (eSIM 11) of the vehicle V. The profile setting unit 113 may validate the profile associated with the trigger after transmitting it to the communication device 10 or may validate the profile stored in advance in the communication device 10.

  Until the profile setting is completed, the profile setting unit 113 repeats the profile setting a predetermined number of times (for example, three times). It is desirable that the profile setting unit 113 repeats the profile setting for a time during which dark current flows through the vehicle V after the power of the vehicle V is turned off. Since the communication control device 100 retries the profile setting several times in this way, the profile setting can be continued even when the profile setting is interrupted due to a temporary factor.

  When the communication apparatus 10 transmits an attach request to the communication control apparatus 100 when the power of the vehicle V is turned on again while the profile setting section 113 repeats the profile setting a predetermined number of times, the profile setting section 113 The profile setting is repeated from the beginning (that is, the repeat count is returned to the initial value). As a result, the communication control apparatus 100 can retry the profile setting more frequently, so that the profile setting is likely to succeed.

  If the profile setting is not completed even after the number of repetitions has expired (that is, failed), the profile setting unit 113 stops the profile setting, and the trigger setting unit 112 resets (enables) the trigger in the storage unit 130. (H). The trigger setting unit 112 may validate the trigger by deleting the invalidation flag set in the trigger information in the storage unit 130, or may validate the trigger by storing the trigger information in the storage unit 130 again. Good. When the attach request is transmitted from the vehicle V after the trigger setting unit 112 resets the trigger, the profile setting unit 113 starts profile setting again for the reset trigger. Thus, the communication control apparatus 100 needs to manage the state of the trigger for each communication apparatus 10 of the vehicle V so that the profile setting can be resumed only by re-enabling the trigger when the profile setting fails. Absent.

  When the profile setting is completed (that is, succeeded), the communication device 10 of the vehicle V transmits completion information indicating completion to the communication control device 100. For example, the communication device 10 transmits completion information using SMS (short message service). When the reception unit 111 receives completion information from the vehicle V, the communication control device 100 ends the communication setting method. The communication device 10 may transmit completion information to the communication control device 100 at each of the timing of completion of reception of the profile from the communication control device 100 and the timing of completion of activation of the profile in the profile setting.

  The profile setting unit 113 of the communication control apparatus 100 receives profile completion information and completes profile validation without sending a profile when profile validation completion information is not received. May be performed. Thereby, for example, when only the reception of the profile is completed in the communication apparatus 10 while the profile setting is repeated, the communication control apparatus 100 can restart the process from the activation of the profile, which is efficient.

  As described above, the communication control apparatus 100 according to the present embodiment invalidates the profile setting trigger (condition) at the start of profile setting, and re-enables the trigger when the profile setting fails, so that the communication apparatus 10 performs communication. Profile settings can be resumed as many times as possible.

[Example of communication sequence for communication setting method]
FIG. 5 is a diagram showing a communication sequence in the communication setting method executed by the communication control apparatus 100 according to the present embodiment. First, the communication apparatus 10 transmits SIM identification information for identifying the eSIM 11, area identification information for the area before movement, and apparatus information including a communication carrier for the area before movement to the communication control apparatus 100 (S <b> 11). The receiving unit 111 of the communication control device 100 receives device information from the vehicle V.

  The trigger setting unit 112 of the communication control device 100 stores trigger information indicating a trigger (condition) for performing profile setting in the storage unit 130 based on the device information received by the receiving unit 111 from the vehicle V. A profile setting trigger is set (S12).

  After the trigger is set, the vehicle V moves to another area and the power is turned on. At this time, the communication device 10 of the vehicle V transmits an attach request including SIM identification information for identifying the eSIM 11 and region identification information of the destination region to the communication control device 100 (S13). The receiving unit 111 of the communication control device 100 receives an attach request from the vehicle V.

  In the communication control apparatus 100, the profile setting unit 113 determines whether or not the attach request received by the receiving unit 111 from the vehicle V satisfies the trigger stored in the storage unit 130 (S14). When the attach request satisfies the trigger, the trigger setting unit 112 invalidates the trigger stored in the storage unit 130, and the profile setting unit 113 starts profile setting (S15).

  Until the profile setting is completed, the profile setting unit 113 repeats the profile setting a predetermined number of times (S16). In the example of FIG. 5, since the vehicle V has transitioned to a state where communication is not possible after the profile setting is started, the profile setting is not completed even if the profile setting is repeated a predetermined number of times. At this time, the profile setting unit 113 stops the profile setting (S17). Then, the trigger setting unit 112 resets (validates) the trigger in the storage unit 130 (S18).

  When the vehicle V transitions to a communicable state after the trigger is reset, the communication device 10 and the communication control device 100 perform steps S13 to S16 again for the reset trigger. When the profile setting is completed, the communication device 10 transmits completion information indicating completion to the communication control device 100 (S19), and the communication control device 100 ends the communication setting method.

[Effect of this embodiment]
The communication control apparatus 100 according to the present embodiment invalidates a profile setting trigger (condition) at the start of profile setting, and re-enables the trigger when the profile setting fails. Thereby, even if the profile setting with respect to the communication apparatus 10 of the vehicle V is interrupted for a long period of time, the communication control apparatus 100 can restart profile setting as many times as the communication apparatus 10 becomes in a communicable state. Furthermore, since the communication control device 100 invalidates the trigger at the start of profile setting, it is not necessary to permanently manage the trigger related to the vehicle for which profile setting has not been completed until profile setting is completed.

(Second Embodiment)
The communication control apparatus 100 according to the first embodiment disables the profile setting trigger at the start of profile setting, whereas the communication control apparatus 100 disables the profile setting trigger at the completion of profile setting. Also in this embodiment, the communication control apparatus 100 can resume profile setting even when the profile setting is interrupted for a long time.

  FIG. 6 is a schematic diagram of a communication setting method executed by the communication control apparatus 100 according to the present embodiment. Compared to FIG. 4, in this embodiment, the trigger invalidation (f) at the start of profile setting and the trigger resetting (h) at the time of profile setting failure are omitted. (I) has been added. Other configurations and processes of the communication control apparatus 100 are the same as those in the first embodiment.

  Specifically, first, the communication device 10 and the communication control device 100 of the vehicle V perform the same (a) to (e) as in FIG. When the attach request satisfies the trigger, the trigger setting unit 112 maintains the trigger stored in the storage unit 130 without invalidating, and the profile setting unit 113 starts profile setting (g). Until profile setting is completed, the profile setting unit 113 repeats profile setting a predetermined number of times.

  If the profile setting is not completed (that is, failed) even after the number of repetitions expires, the profile setting unit 113 stops the profile setting. At this time, since the trigger stored in the storage unit 130 is not invalidated, the trigger setting unit 112 does not reset the trigger. Thereafter, when an attach request is transmitted from the vehicle V again, the profile setting unit 113 starts profile setting again for the trigger maintained in the storage unit 130.

  When the profile setting is completed (that is, succeeded) within a predetermined number of times, the trigger setting unit 112 invalidates the trigger stored in the storage unit 130 (i). The trigger setting unit 112 may invalidate the trigger by setting an invalidation flag in the trigger information stored in the storage unit 130, or invalidate the trigger by deleting the trigger information stored in the storage unit 130. May be.

[Example of communication sequence for communication setting method]
FIG. 7 is a diagram showing a communication sequence in the communication setting method executed by the communication control apparatus 100 according to the present embodiment. First, the communication apparatus 10 transmits SIM identification information for identifying the eSIM 11, area identification information for the area before movement, and apparatus information including a communication carrier for the area before movement to the communication control apparatus 100 (S <b> 11). The receiving unit 111 of the communication control device 100 receives device information from the vehicle V.

  The trigger setting unit 112 of the communication control device 100 stores trigger information indicating a trigger (condition) for performing profile setting in the storage unit 130 based on the device information received by the receiving unit 111 from the vehicle V. A profile setting trigger is set (S12).

  After the trigger is set, the vehicle V moves to another area and the power is turned on. At this time, the communication device 10 of the vehicle V transmits an attach request including SIM identification information for identifying the eSIM 11 and region identification information of the destination region to the communication control device 100 (S13). The receiving unit 111 of the communication control device 100 receives an attach request from the vehicle V.

  In the communication control apparatus 100, the profile setting unit 113 determines whether or not the attach request received by the receiving unit 111 from the vehicle V satisfies the trigger stored in the storage unit 130 (S14). When the attach request satisfies the trigger, the trigger setting unit 112 maintains the trigger stored in the storage unit 130, and the profile setting unit 113 starts profile setting (S15 ').

  Until the profile setting is completed, the profile setting unit 113 repeats the profile setting a predetermined number of times (S16). In the example of FIG. 7, since the vehicle V has transitioned to a state incapable of communication after the profile setting is started, the profile setting is not completed even if the profile setting is repeated a predetermined number of times. At this time, the profile setting unit 113 stops the profile setting (S17). The trigger setting unit 112 does not reset the trigger.

  When the vehicle V transitions to a communicable state after the trigger is reset, the communication device 10 and the communication control device 100 perform steps S13 to S16 again for the reset trigger. When the profile setting is completed, the communication device 10 transmits completion information indicating completion to the communication control device 100 (S19). When the receiving unit 111 of the communication control device 100 receives the completion information from the communication device 10, the trigger setting unit 112 invalidates the trigger stored in the storage unit 130 (S20).

[Effect of this embodiment]
Thus, the communication control apparatus 100 according to the present embodiment maintains a profile setting trigger (condition) at the start of profile setting, and invalidates the trigger when the profile setting is completed. Thereby, even if the profile setting with respect to the communication apparatus 10 of the vehicle V is interrupted for a long period of time, the communication control apparatus 100 can restart profile setting as many times as the communication apparatus 10 becomes in a communicable state. Furthermore, the trigger setting and invalidation processing required for one profile setting need only be performed once. Therefore, it is possible to reduce the load applied to the communication control apparatus 100 by profile setting (remote provisioning).

  In the above-described embodiments, the communication device 10 mounted on the vehicle V has been described. However, the application destination of the communication control device 100 is not limited to this.
