- 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).

- 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.
- the communication control apparatus 100 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.

- the communication device 10 of the vehicle V transmits completion information indicating completion to the communication control device 100 when profile setting is completed (that is, profile setting is successful). For example, the communication device 10 transmits completion information using SMS (short message service).
- 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.
- the communication control apparatus 100 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.

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.
- the communication control apparatus 100 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.

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 ').
- 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.

図3は、本実施形態に係る通信制御装置100のブロック図である。図3において、矢印は主なデータの流れを示しており、図3に示していないデータの流れがあってよい。図3において、各ブロックはハードウェア(装置)単位の構成ではなく、機能単位の構成を示している。そのため、図3に示すブロックは単一の装置内に実装されてよく、あるいは複数の装置内に別れて実装されてよい。ブロック間のデータの授受は、データバス、ネットワーク、可搬記憶媒体等、任意の手段を介して行われてよい。
図4は、本実施形態に係る通信制御装置100が実行する通信設定方法の模式図である。図4は、第1地域(例えば第1国)において通信可能な車両Vが、第1地域とは異なる第2地域(例えば第2国)に移動する状況を示している。第1地域において、車両VのeSIM11には、リモートプロビジョニングによって、あるいは直接(例えばプロファイル設定用の端末に接触させることによって)、予めプロファイル設定が行われている。
図5は、本実施形態に係る通信制御装置100が実行する通信設定方法における通信シーケンスを示す図である。まず通信装置10は、装置情報を、通信制御装置100に送信する(S11)。この装置情報は、eSIM11を識別するSIM識別情報、移動前の地域の地域識別情報、及び移動前の地域の通信事業者等を含む。通信制御装置100の受信部111は、車両Vからの装置情報を受信する。
本実施形態に係る通信制御装置100は、プロファイル設定の開始時にプロファイル設定のトリガ(条件)を無効化し、プロファイル設定が失敗した場合にトリガを再度有効化する。これにより通信制御装置100は、車両Vの通信装置10に対するプロファイル設定が長期間中断した場合であっても、通信装置10が通信可能な状態になれば何度でもプロファイル設定を再開できる。さらに、通信制御装置100は、プロファイル設定の開始時にトリガを無効化するため、プロファイル設定未完了の車両に係るトリガをプロファイル設定完了まで永続的に管理する必要がない。
第1の実施形態に係る通信制御装置100はプロファイル設定の開始時にプロファイル設定のトリガを無効化するのに対して、通信制御装置100はプロファイル設定の完了時にプロファイル設定のトリガを無効化する。本実施形態においても、通信制御装置100は、プロファイル設定が長期間中断した場合であってもプロファイル設定を再開できる。
図7は、本実施形態に係る通信制御装置100が実行する通信設定方法における通信シーケンスを示す図である。
まず通信装置10は、装置情報を、通信制御装置100に送信する(S11)。この装置情報は、eSIM11を識別するSIM識別情報、移動前の地域の地域識別情報、及び移動前の地域の通信事業者等を含む。通信制御装置100の受信部111は、車両Vからの装置情報を受信する。
プロファイル設定が完了すると、通信装置10は完了を示す完了情報を通信制御装置100に送信する(S19)。通信制御装置100の受信部111が通信装置10から完了情報を受信すると、トリガ設定部112は記憶部130に記憶されたトリガを無効化する(S20)。
このように本実施形態に係る通信制御装置100は、プロファイル設定の開始時にプロファイル設定のトリガ(条件)を維持し、プロファイル設定が完了した場合にトリガを無効化する。これにより通信制御装置100は、車両Vの通信装置10に対するプロファイル設定が長期間中断した場合であっても、通信装置10が通信可能な状態になれば何度でもプロファイル設定を再開できる。さらに、1回のプロファイル設定に必要なトリガの設定及び無効化の処理がそれぞれ1回だけで済む。そのため、プロファイル設定(リモートプロビジョニング)によって通信制御装置100に掛かる負荷を低減できる。
