まず、本発明の実施形態にかかる通信システムについて説明する。本実施形態にかかる通信システムは、通信システムを構成する通信装置および情報管理装置が特筆すべき特徴を有する。具体的には、通信装置は、自装置の位置を示す位置情報を取得して情報管理装置に送信する機能、検知した基地局の識別情報を取得して情報管理装置に送信する機能を有する。また、情報管理装置は、通信装置から送信された位置情報と基地局識別情報とを対応付けて登録する機能を有する。以下、図1~図14を用いて説明する。
図2は、本実施形態にかかる通信装置40の機能構成を示したブロック図である。通信装置40は、通信部410と、測位部421と、基地局検知部422と、履歴情報登録部430と、履歴情報記憶部440と、送信制御部450とを備えるものである。また、通信装置40は、さらに、移動手段識別情報取得部445、制御部460、表示部470、情報更新部480、基地局情報記憶部490等を備えることとしてもよい。移動手段識別情報取得部445が有する機能については[11. 履歴情報に移動手段識別情報を含める場合についての説明]以降にて説明する。
図3は、本実施形態にかかる情報管理装置20の機能構成を示したブロック図である。情報管理装置20は、通信部210と、記憶部220と、基地局情報登録部240と、履歴情報登録部260とを備えるものである。また、情報管理装置20は、さらに、登録判断部230、送信制御部250等を備えることとしてもよい。登録判断部230については、図4を参照して後述する。
図4は、履歴情報に時刻情報を含める場合について説明する図である。上述したように、基地局情報登録部240は、記憶部220に登録されている位置情報取得履歴情報に含まれる位置情報と記憶部220に登録されている基地局ID取得履歴情報に含まれる基地局IDとを対応付けてなる基地局情報を記憶部220に登録する。しかし、基地局情報登録部240は、記憶部220に登録されている位置情報取得履歴情報に含まれる位置情報と記憶部220に登録されている基地局ID取得履歴情報に含まれる基地局IDとを必要に応じて対応付けて記憶部220に登録することとしてもよい。例えば、基地局IDを取得した時刻と位置情報を取得した時刻との時間差が大きいほど、基地局IDを取得した位置と位置情報を取得した位置との誤差が大きくなることが想定される。そこで、基地局IDと対応付けるべき位置情報としては、基地局IDを取得した時刻との時間差の小さい時刻に取得したものであることが好ましい。
図5は、位置情報取得履歴情報のデータ構造(その1)の一例を示す図である。図5に示したように、位置情報取得履歴情報は、複数の時点における通信装置40の位置情報が、該通信装置40の位置情報が得られた時刻を示す時刻情報と対応付けられて構成される。具体的に、図5に示した例では、位置情報取得履歴情報は、時刻t1、t2、t3、t4およびt5とその各時刻情報に得られた位置情報とが対応付けられて構成されている。なお、位置情報取得履歴情報は、必ずしも時刻情報を含むものである必要はない。
図6は、基地局ID取得履歴情報のデータ構造の一例を示す図である。図6に示したように、基地局ID取得履歴情報は、複数の時点における通信装置40が取得した基地局IDが、該基地局IDを取得した時刻を示す時刻情報と対応付けられて構成される。具体的に、図6に示した例では、基地局ID取得履歴情報は、時刻T1、T2およびT3とその各時刻情報に得られた基地局IDとが対応付けられて構成されている。なお、基地局ID取得履歴情報は、必ずしも時刻情報を含むものである必要はない。

以上に説明した例では、通信装置40を携帯しているユーザが一定の速度で移動すると仮定した。そのために、情報管理装置20の記憶部220は、ユーザの移動速度に依存しない閾値を記憶していれば足りていた。しかしながら、ユーザの移動速度は時々刻々変化しているのが通常であり、移動速度の変化を反映させて基地局情報を記憶部220に登録するには、情報管理装置20の記憶部220が記憶する閾値をユーザの速度に応じて変更するのが好ましい。
図11は、位置情報取得履歴情報のデータ構造(その2)の一例を示す図である。図11に示したように、位置情報取得履歴情報は、複数の時点における通信装置40の位置情報だけでなく、通信装置40の移動手段識別情報も該通信装置40の位置情報が得られた時刻を示す時刻情報に対応付けられて構成される。具体的に、図11に示した例では、位置情報取得履歴情報は、時刻t1、t2、t3、t4およびt5とその各時刻情報に得られた位置情報とその各時刻情報における移動手段識別情報(電車、電車、徒歩、徒歩および電車)とが対応付けられて構成されている。なお、位置情報取得履歴情報は、必ずしも移動手段識別情報を含むものである必要はない。また、移動手段識別情報として示した電車や徒歩については、移動手段識別情報の一例にすぎず、移動手段識別情報はこれらに限定されるものではない。
図12は、移動手段情報のデータ構造の一例を示す図である。図12に示したように、移動情報は、通信装置40の移動手段を識別するための移動手段識別情報と閾値とが対応付けられて構成される。具体的に、図12に示した例では、移動情報は、移動手段識別情報(電車、乗用車、自転車および徒歩)とその移動手段識別情報で識別される移動手段における閾値(2秒、3秒、4秒および5秒)とが対応付けられて構成されている。なお、移動情報は、必ずしも存在する必要はない。また、閾値として示した時間については、閾値の一例にすぎず、閾値はこれらに限定されるものではない。

以上説明したように、本発明の実施形態にかかる通信システム10によれば、基地局の設置位置を示す位置情報を情報管理装置20の記憶部220が記憶する基地局情報に自動的に反映させることができる。すなわち、情報管理装置20に基地局情報をユーザが設定する手間を抑制することができる。
なお、添付図面を参照しながら本発明の好適な実施形態について説明したが、本発明は係る例に限定されないことは言うまでもない。当業者であれば、特許請求の範囲に記載された範疇内において、各種の変更例または修正例に想到し得ることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。
