That is, when the position information confirmation unit 13 acquires the position information immediately after the determination in S22, it may not be possible to detect that the user has left the home. Therefore, after the determination of S22 is completed, the process of S23 may be performed after a certain time (for example, 5 minutes) has elapsed, or after the mobile terminal 100 is confirmed to be moving, the process of S23 may be performed. Processing may be performed. Whether or not the mobile terminal 100 is moving can be confirmed using sensor information such as an acceleration sensor (not shown) or a geomagnetic sensor (not shown) provided in the mobile terminal 100, for example.

There is a possibility that it cannot be correctly determined that the vehicle is outside (in a predetermined range) outside the departure detection point (here, home). Therefore, the position information is acquired in order to correctly determine whether or not the mobile terminal 100 has left the departure detection point. However, in order to reduce power consumption, it is desirable to reduce the number of times the position information is acquired.
- the mobile terminal 100 when the mobile terminal 100 leaves the range where wireless communication via the access point 50 registered in advance is possible, the mobile terminal 100 acquires the current position information of the mobile terminal 100 and the mobile terminal 100 It is determined whether or not it exists outside the home. As a result, it is possible to acquire location information only when the mobile terminal 100 detects that it has left the range where wireless communication via the access point 50 is possible, and to specify that it is currently outside the home. it can.

Abstract
Description
以下、本発明の実施の形態について、ここでは、本発明に係る携帯端末として、GPS機能などの測位機能を備え、現在の位置を測位することが可能であり、かつ、Wi-Fi(登録商標)やBluetooth(登録商標)などのアクセスポイント(AP)50(機器)の無線通信圏において、該アクセスポイント50と無線通信が可能な携帯端末100を例に挙げて説明する。なお、携帯端末100は、ユーザとともに移動するスマートフォン、携帯電話、およびタブレット端末などの移動体装置であってもよいが、自機の位置情報の取得機能を備えており、かつ、アクセスポイント50との無線通信が可能であれば、如何なる通信端末であってもよい。また、ここでは携帯端末100がアクセスポイント50との接続を契機にして、現在の位置を測位する例を説明するが、アクセスポイント50との接続に限定されない。携帯端末100との無線通信が可能な任意の機器との接続を本発明に適用することができる。
携帯端末100は、到達を検知したい地点(以下、「到達検知地点」と記載する)で使用されているアクセスポイント50への接続を契機として、GPS機能による測位(位置測位)を行い、当該到達検知地点(所定の範囲内)に到達したか否かを判定する。なお、到達検知地点は、ある程度の広がりを持った範囲(所定の範囲)を占め、携帯端末100がこの範囲内に入ったときに、携帯端末100のユーザが到達検知地点に到達したと判定する。また、到達検知地点の付近には、アクセスポイント50が存在している。このため、アクセスポイント50を介した無線通信が可能な範囲(無線通信圏)に存在する携帯端末100は、到達検知地点に到達しているか、または到達検知地点の近くに存在していると言える。
続いて、制御部10の構成について、以下に説明する。制御部10は、接続制御部11、アクセスポイント照合部12(検出部)、位置情報確認部13(位置特定部)、および処理実行部14を備えている。
次に、アクセスポイント識別情報21について、図2を用いて説明する。図2は、アクセスポイント識別情報21のデータ構造の一例を示す図である。
次に、記憶部20の登録位置情報22について、図3を用いて説明する。図3は、登録位置情報22のデータ構造の一例を示す図である。登録位置情報22は、図3に示すように、到達検知地点毎の位置情報と各到達検知地点にて実行する処理との対応関係を規定するテーブルであってもよい。
到達検知地点がユーザの自宅である場合を例に挙げて、自宅のアクセスポイント(AP)50、およびMACアドレスを携帯端末100に登録する処理の流れについて図4を用いて説明する。図4は、自宅で、Wi-Fiのアクセスポイント50を携帯端末100に登録する処理の流れの一例を説明するフローチャートである。この処理により、アクセスポイント識別情報21が記録される。なお、到達検知地点が自宅以外(例えば、商業施設、観光施設、勤務先など)であっても、図4に示す処理と同様にして、アクセスポイント50、およびMACアドレスを登録することが可能である。
続いて、到達検知地点のアクセスポイント50との接続を契機にして、現在の位置を測位する処理の流れについて、図5を用いて説明する。図5は、登録済の到達検知地点のWi-Fiのアクセスポイント50との接続を契機にして、現在の位置を測位する処理の流れの一例を説明するフローチャートである。なお、ここでは、到達検知地点が自宅である例を説明する。
上述の実施形態に係る携帯端末100は、到達検知地点のアクセスポイント50との接続を契機にして現在の位置を測位して、ユーザが到達検知地点に到達したか否かを判定し、所定の処理を実行する場合について説明したが、これに限定されない。例えば、離脱を検知したい地点(以下、「離脱検知地点」と記載する)のアクセスポイント50との接続を切断したことを契機にして現在の位置を測位して、ユーザが離脱検知地点と異なる場所(所定の範囲)に存在しているか否かを判定し、所定の処理を実行してもよい。このような実施形態について、図6に基づいて説明すれば、以下のとおりである。なお、説明の便宜上、前記実施形態にて説明した部材と同じ機能を有する部材については、同じ符号を付記し、その説明を省略する。
ここでは、離脱検知地点のアクセスポイント50との接続の切断を契機にして、現在の位置を測位する処理の流れについて、図6を用いて説明する。図6は、登録済の自宅のWi-Fiのアクセスポイント50との接続を切断したことを契機にして、現在の位置を測位する処理の流れの一例を説明するフローチャートである。なお、ここでは、離脱検知地点が自宅である例を説明する。
例えば、ユーザが携帯端末100の無線通信機能の有効化/無効化を切り替える操作を受け付けたり、携帯端末100の電源のON/OFFを切り替える操作を受け付けたりした場合、ユーザが到達検知地点に到達したり、離脱検知地点から離れたりすることなく、携帯端末100とアクセスポイント50との無線通信が接続したり、切断したりする場合がある。また、携帯端末100がスリープ状態へ遷移したり、スリープ状態から復帰して動作状態になったりした場合も同様に、携帯端末100とアクセスポイント50との無線通信が接続したり、切断したりする。ユーザの移動を伴わないこのような場合に測位を行うことは、無駄である場合がある。
携帯端末100の制御ブロック(特に接続制御部11、アクセスポイント照合部12、位置情報確認部13、および処理実行部14)および位置情報取得部40は、集積回路(ICチップ)等に形成された論理回路(ハードウェア)によって実現してもよいし、CPU(Central Processing Unit)を用いてソフトウェアによって実現してもよい。
