Description

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

In recent years, vehicles capable of communicating by being equipped with a communication device have been sold. Vehicles may be manufactured in one country and then shipped to another country for sale. In this case, a profile (communication profile) is set in the communication device provided in the vehicle so that communication can be performed using the communication service provided by the business operator in the destination country. The setting process that remotely provides a profile to a communication device and activates it is called remote provisioning.

Patent Documents 1 and 2 describe a new method in which when a terminal moves from an area where one operator provides a communication service to an area where a different operator provides a communication service, the terminal corresponds to the destination operator. The technology to set a different profile remotely is described.

U.S. Pat. No. 985,5000 U.S. Patent Application Publication No. 2016/01/92312

By the way, it is known that it takes about several minutes to 10 minutes to set a profile remotely 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 for a long time in a non-communicable place such as underground.

The techniques described in Patent Documents 1 and 2 do not assume that the profile setting is interrupted for a long period of time. It is inefficient to infinitely retry the profile setting in the techniques described in Patent Documents 1 and 2 when the vehicle is stored for a long period of time (for example, several months or more). On the other hand, if the retry of the profile setting is limited to a predetermined number of times, the profile setting cannot be restarted even if the vehicle becomes communicable after the number of retries has expired.

The present invention has been made in view of these points, and even if the remote profile setting for the communication device is interrupted for a long period of time, the setting is made when the communication device becomes communicable.

The storage unit stores the condition indicating the area corresponding to the profile, the receiving unit receives the signal indicating the area with which the communication device communicates, and the profile setting unit indicates the signal. The setting of the profile may be started on the condition that the area and the area indicated by the condition match.

The profile setting unit may repeat the setting of the profile a predetermined number of times, and if the setting of the profile is not successful even after the predetermined number of times expires, it may be determined that the setting of the profile has failed.

If the receiving unit receives the signal before the predetermined number of times expires, the profile setting unit may return the number of times of repeating the setting of the profile to the initial value.

The profile setting unit sets the profile by transmitting the profile to the communication device and then activating the profile on the communication device, and the receiving unit receives the profile from the communication device. Information indicating the completion and information indicating the completion of activation of the profile may be received.

(First Embodiment)
[Overview 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 vehicle V and base station B included in the communication system S is not limited. The communication system S may include other devices such as servers and terminals.

The base station B is a wireless base station device capable of performing wireless communication (mobile communication) such as LTE (Long Term Evolution). The base station B is provided with 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 it can communicate. The base station B relays the communication between the communication device and the network N such as the Internet.

Vehicle V is a vehicle such as an automobile, a motorcycle, or a self-propelled construction machine. The vehicle V is provided with a communication device, and is configured to be capable of wireless communication 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 the 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 device 100 is connected to the network N by wire or wirelessly. Although the communication control device 100 is described as one device in FIG. 1, it may be composed of a plurality of devices.

FIG. 2 is a schematic diagram of profile setting performed by the communication control device 100 with respect to the communication device 10 of the vehicle V. The vehicle V has 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. Further, 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 communicating using a communication service provided by a business operator. For example, the profile includes the IMSI (International Mobile Subscriber Identity), and the IMSI includes the MCC (Mobile Country Code) which is the area identification information for identifying the area (country, etc.) to which the communication service is provided. 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 device 100 via the network N.

Further, the eSIM 11 stores the enabled or disabled state for each profile stored internally. Each profile stored inside the eSIM 11 is enabled or disabled by the communication control device 100 via the network N (ie, remotely). The communication device 10 communicates based on the profile activated in the eSIM 11. The fact that the communication control device 100 activates the profile stored in advance in the eSIM 11 or that the communication control device 100 transmits the profile to the eSIM 11 and activates the profile is called profile setting.

When a business operator of the vehicle V moves from an area where a business operator provides a communication service to an area where a different business operator provides a communication service, the communication device 10 of the vehicle V makes a profile setting request to the communication control device 100. When the communication control device 100 receives a profile setting request from the communication device 10, the communication control device 100 remotely sets a profile for the communication device 10 (eSIM11). When the profile setting is completed, the communication device 10 can communicate in the area after the movement.

It takes about several minutes to 10 minutes to set a profile remotely for the communication device 10. If the vehicle V moves to a place where communication is not possible, 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 period of time (for example, several months or more), infinitely retrying the profile setting results in a large waste of communication cost and management cost. Further, if the number of retries of the profile setting is limited, the profile setting cannot be restarted even if the vehicle V becomes communicable after the number of retries has expired.

On the other hand, the communication control device 100 according to the present embodiment can restart the profile setting even if the profile setting is interrupted for a long period of 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 device 100 according to the present embodiment. In FIG. 3, the arrows indicate the main data flows, and there may be data flows not shown in FIG. In FIG. 3, each block shows not a hardware (device) unit configuration but a functional unit configuration. Therefore, the block shown in FIG. 3 may be mounted in a single device, or may be mounted separately in a plurality of devices. Data can be exchanged between blocks via any means such as a data bus, a network, or a portable storage medium.

The communication control device 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 device 100 according to the present embodiment is not limited to the specific configuration shown 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 executing wireless communication. The communication unit 120 performs predetermined processing on the communication signal received from the outside to acquire data, and inputs the acquired data to the control unit 110. Further, the communication unit 120 performs a predetermined process 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 in advance a program executed by the control unit 110. Further, the storage unit 130 stores the trigger information indicating the conditions for setting the profile for the communication device 10 and the profile information indicating the profile to be set for the communication device 10.

The control unit 110 is, for example, a processor such as a CPU (Central Processing Unit), and functions as a reception unit 111, a trigger setting unit 112, and a 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 some of the functions of the control unit 110 may be performed by an electric circuit. Further, at least a part of the functions of the control unit 110 may be executed by a program executed via the network.

[Explanation of communication setting method]
FIG. 4 is a schematic diagram of a communication setting method executed by the communication control device 100 according to the present embodiment. FIG. 4 shows a situation in which a vehicle V communicable in a first region (for example, a first country) moves to a second region (for example, a second country) different from the first region. In the first region, the eSIM11 of the vehicle V is profiled in advance by remote provisioning or directly (for example, by contacting a terminal for profile setting).

With the power of the vehicle V turned on in the first area, the communication device 10 of the vehicle V provides SIM identification information for identifying the eSIM 11, area identification information for the first area, a telecommunications carrier in the first area, and the like. The device information including the device information is transmitted to the communication control device 100 via the base station B in the first area (that is, the area before the movement) (a). After that, the power of the vehicle V is turned off. The receiving unit 111 of the communication control device 100 receives the 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 the trigger information indicating the trigger (condition) for setting the profile in the storage unit 130 based on the device information received from the vehicle V. , Set the trigger for profile setting (b).

For example, the trigger information includes SIM identification information that identifies the eSIM 11 and area identification information (MCC) that corresponds to the profile used in the destination area (here, the second area). The trigger information may be input to the communication control device 100 by the administrator, or may be automatically determined according to a predetermined rule based on the device information. Further, the trigger setting unit 112 associates the profile information indicating the 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 the trigger, the vehicle V moves from the first area to the second area by being transported by a ship or the like in a state where the power is turned off (c). When the power of the vehicle V is turned on (that is, the vehicle V is energized) in the second region, the communication device 10 of the vehicle V sends an attach request to the communication control device 100 via the base station B in the second region. Send (d). The attach request is a signal for the communication device 10 to start communication, and the SIM identification information that identifies the eSIM 11 and the area identification information (MCC) corresponding to the area (here, the second area) where the communication is to be started. And include. The transmission of the attach request from the communication device 10 to the base station B in the second area can be performed even outside the service area of the contracted business operator (here, the business operator in the first region) due to the alliance between the business operators. , It is performed by a service (roaming, etc.) that enables communication if it is within the service area of the partner company (here, the company in the second region).

In the communication control device 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 when the SIM identification information and the area identification information indicated by the trigger information stored in the storage unit 130 match the SIM identification information and the area identification information indicated by the attach request. Determined to meet. If not, the profile setting unit 113 determines that the trigger is not satisfied. The trigger determination method shown here is an example, and another method capable of determining the necessity of profile setting by using a trigger based on the area with which the vehicle V communicates may be used.

When the attach request does not satisfy the trigger, the profile setting unit 113 does not set the profile, 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 the invalidation flag in the trigger information stored in the storage unit 130, and deletes the trigger information stored in the storage unit 130 to cause the trigger. 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 (eSIM11) of the vehicle V. The profile setting unit 113 may transmit the profile associated with the trigger to the communication device 10 and then activate the profile, or may activate the profile stored in advance in the communication device 10.

The profile setting unit 113 repeats the profile setting a predetermined number of times (for example, three times) until the profile setting is completed. It is desirable that the profile setting unit 113 repeats the profile setting during the time when the 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 if the profile setting is interrupted due to a temporary factor.

When the communication device 10 transmits an attach request to the communication control device 100 by turning on the power of the vehicle V again while the profile setting unit 113 repeats the profile setting a predetermined number of times, the profile setting unit 113 , Repeat the profile setting from the beginning (that is, return the number of repetitions to the initial value). As a result, the communication control device 100 can retry the profile setting more, which makes it easier for the profile setting to succeed.

If the profile setting is not completed (that is, fails) even after the number of repetitions has expired, the profile setting unit 113 cancels 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 enable the trigger by deleting the invalidation flag set in the trigger information in the storage unit 130, or may enable the trigger by storing the trigger information in the storage unit 130 again. Good. If an 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. In this way, the communication control device 100 needs to manage the trigger state for each communication device 10 of the vehicle V so that the profile setting can be restarted only by re-enabling the trigger when the profile setting fails. Absent.

When the profile setting is completed (that is, successful), the communication device 10 of the vehicle V transmits the completion information indicating the completion to the communication control device 100. For example, the communication device 10 transmits completion information using SMS (Short Message Service). The communication control device 100 ends the communication setting method when the receiving unit 111 receives the completion information from the vehicle V. The communication device 10 may transmit completion information to the communication control device 100 at each of the timing of completion of receiving the profile from the communication control device 100 and the timing of completion of activation of the profile in the profile setting.

When the profile setting unit 113 of the communication control device 100 receives the completion information of the completion of receiving the profile and has not received the completion information of the completion of activation of the profile, the profile is activated without transmitting the profile. May be done. As a result, for example, when only the reception of the profile is completed in the communication device 10 during the repetition of the profile setting, the communication control device 100 can restart the process from the activation of the profile, which is efficient.

As described above, in the communication control device 100 according to the present embodiment, the trigger (condition) of the profile setting is invalidated at the start of the profile setting, and the trigger is re-enabled when the profile setting fails, so that the communication device 10 communicates. You can resume profile settings as many times as you can.

[Example of communication sequence of communication setting method]
FIG. 5 is a diagram showing a communication sequence in the communication setting method executed by the communication control device 100 according to the present embodiment. First, the communication device 10 transmits the SIM identification information that identifies the eSIM 11, the area identification information of the area before the movement, and the device information including the communication carrier in the area before the movement to the communication control device 100 (S11). The receiving unit 111 of the communication control device 100 receives the device information from the vehicle V.

The trigger setting unit 112 of the communication control device 100 stores the trigger information indicating the trigger (condition) for setting the profile in the storage unit 130 based on the device information received from the vehicle V by the reception unit 111. A trigger for profile setting 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 the SIM identification information for identifying the eSIM 11 and the area identification information of the destination area to the communication control device 100 (S13). The receiving unit 111 of the communication control device 100 receives the attach request from the vehicle V.

In the communication control device 100, the profile setting unit 113 determines whether or not the attach request received from the vehicle V by the reception unit 111 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 the profile setting (S15).

The profile setting unit 113 repeats the profile setting a predetermined number of times until the profile setting is completed (S16). In the example of FIG. 5, since the vehicle V has transitioned to a state in which communication is not possible after the profile setting is started, it is assumed that 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 cancels the profile setting (S17). Then, the trigger setting unit 112 resets (enables) 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 the completion information indicating the 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 device 100 according to the present embodiment invalidates the profile setting trigger (condition) at the start of the profile setting, and re-enables the trigger when the profile setting fails. As a result, even if the profile setting for the communication device 10 of the vehicle V is interrupted for a long period of time, the communication control device 100 can resume the profile setting as many times as the communication device 10 becomes communicable. Further, since the communication control device 100 invalidates the trigger at the start of the profile setting, it is not necessary to permanently manage the trigger related to the vehicle for which the profile setting has not been completed until the profile setting is completed.

(Second Embodiment)
The communication control device 100 according to the first embodiment invalidates the profile setting trigger at the start of the profile setting, whereas the communication control device 100 invalidates the profile setting trigger at the completion of the profile setting. Also in this embodiment, the communication control device 100 can restart the profile setting even if the profile setting is interrupted for a long period of time.

FIG. 6 is a schematic diagram of a communication setting method executed by the communication control device 100 according to the present embodiment. In the present embodiment, as compared with FIG. 4, invalidation of the trigger at the start of profile setting (f) and resetting of the trigger at the time of failure of profile setting (h) are omitted, and instead, invalidation of the trigger at the completion of profile setting is performed. (I) has been added. Other than that, the configuration and processing of the communication control device 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 steps (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 it, and the profile setting unit 113 starts the profile setting (g). The profile setting unit 113 repeats the profile setting a predetermined number of times until the profile setting is completed.

If the profile setting is not completed (that is, fails) even after the number of repetitions has expired, the profile setting unit 113 cancels 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. After that, when the 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 the invalidation flag in the trigger information stored in the storage unit 130, or invalidates the trigger by deleting the trigger information stored in the storage unit 130. You may.

[Example of communication sequence of communication setting method]
FIG. 7 is a diagram showing a communication sequence in the communication setting method executed by the communication control device 100 according to the present embodiment. First, the communication device 10 transmits the SIM identification information that identifies the eSIM 11, the area identification information of the area before the movement, and the device information including the communication carrier in the area before the movement to the communication control device 100 (S11). The receiving unit 111 of the communication control device 100 receives the device information from the vehicle V.

The trigger setting unit 112 of the communication control device 100 stores the trigger information indicating the trigger (condition) for setting the profile in the storage unit 130 based on the device information received from the vehicle V by the reception unit 111. A trigger for profile setting 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 the SIM identification information for identifying the eSIM 11 and the area identification information of the destination area to the communication control device 100 (S13). The receiving unit 111 of the communication control device 100 receives the attach request from the vehicle V.

In the communication control device 100, the profile setting unit 113 determines whether or not the attach request received from the vehicle V by the reception unit 111 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 the profile setting (S15').

The profile setting unit 113 repeats the profile setting a predetermined number of times until the profile setting is completed (S16). In the example of FIG. 7, since the vehicle V has transitioned to a state in which communication is not possible after the profile setting is started, it is assumed that 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 cancels 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 the completion information indicating the 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]
As described above, the communication control device 100 according to the present embodiment maintains the trigger (condition) of the profile setting at the start of the profile setting, and invalidates the trigger when the profile setting is completed. As a result, even if the profile setting for the communication device 10 of the vehicle V is interrupted for a long period of time, the communication control device 100 can resume the profile setting as many times as the communication device 10 becomes communicable. Further, the trigger setting and invalidation processing required for one profile setting need to be performed only once. Therefore, the load on the communication control device 100 can be reduced by profile setting (remote provisioning).

In each of the above-described embodiments, the communication device 10 mounted on the vehicle V has been described, but the application destination of the communication control device 100 is not limited to this. For example, the communication control device 100 can also be applied to communication settings for communication devices mounted on ships, IoT devices, and the like. In particular, since the battery capacity of the vehicle V is limited, the power-on time is often short when moving or storing.
