Description
本発明は、携帯端末によって実行されるコンピュータプログラムに関する。 The present invention relates to a computer program executed by a mobile terminal.
特許文献１には、移動通信端末、測位システム、測位方法およびプログラムが開示されている。特許文献１の図７を参照すると、特許文献１に記載の発明では、常時位置を把握するために一定の時間間隔で測位を実行する。そして、図８に示されるように、ハンドオーバの頻度が高い場合はＧＰＳ測位をオフにしてセクタ測位をオンにし、低い場合はＧＰＳ測位をオンにしてセクタ測位をオフにする。 Patent Document 1 discloses a mobile communication terminal, a positioning system, a positioning method, and a program. Referring to FIG. 7 of Patent Document 1, in the invention described in Patent Document 1, positioning is performed at regular time intervals in order to grasp the position at all times. As shown in FIG. 8, when the frequency of handover is high, the GPS positioning is turned off and the sector positioning is turned on, and when the frequency is low, the GPS positioning is turned on and the sector positioning is turned off.
しかしながら、特許文献１に記載の技術では一定の時間間隔で測位を実行するので、場合によってはユーザの位置がほとんど変わっていないのに連続して測位が実行されるなど無駄に測位が実行される可能性がある。 However, in the technique described in Patent Document 1, since positioning is performed at regular time intervals, positioning is performed wastefully, for example, positioning is continuously performed even though the position of the user has hardly changed. there is a possibility.
本発明はこうした課題に鑑みてなされたものであり、その目的は、無駄な測位処理の発生を抑制できるコンピュータプログラムの提供にある。 The present invention has been made in view of these problems, and an object thereof is to provide a computer program capable of suppressing the occurrence of useless positioning processing.
本発明のある態様はコンピュータプログラムに関する。このコンピュータプログラムは、ハンドオーバが発生するたびに測位システムを使用した測位処理を実行する機能を携帯端末に実現させる。 One embodiment of the present invention relates to a computer program. This computer program causes a mobile terminal to realize a function of executing a positioning process using a positioning system every time a handover occurs.
なお、以上の構成要素の任意の組み合わせや、本発明の構成要素や表現を方法、システム、コンピュータプログラム、コンピュータプログラムを格納した記録媒体などの間で相互に置換したものもまた、本発明の態様として有効である。 It should be noted that any combination of the above-described constituent elements, or the constituent elements and expressions of the present invention replaced with each other among methods, systems, computer programs, recording media storing computer programs, etc. are also aspects of the present invention. It is effective as
以下、各図面に示される同一または同等の構成要素、部材、処理には、同一の符号を付するものとし、適宜重複した説明は省略する。 Hereinafter, the same or equivalent components, members, and processes shown in the drawings are denoted by the same reference numerals, and repeated description is appropriately omitted.
実施の形態に係るコンピュータプログラムは、サーバからインターネットなどのネットワークを介して携帯端末すなわち携帯電話にダウンロードされ、その携帯電話によって実行されるコンピュータプログラムである。携帯電話はいわゆるスマートホンなどであってもよく、タッチパネル、通話機能およびＷｅｂ通信機能を有し、ウェブブラウザを有していてもよい。携帯電話にはiPhone（登録商標）OS4などのマルチタスク対応のオペレーティングシステムが導入されている。 The computer program according to the embodiment is a computer program that is downloaded from a server to a mobile terminal, that is, a mobile phone via a network such as the Internet and executed by the mobile phone. The mobile phone may be a so-called smart phone or the like, and may have a touch panel, a call function, a web communication function, and a web browser. A multitasking operating system such as iPhone (registered trademark) OS4 has been introduced to mobile phones.
本実施の形態に係るコンピュータプログラムは、例えばインターネット上のスマートホン用アプリケーションダウンロードサイトからダウンロードされるスマートホン用のアプリケーションプログラムであってもよく、あるいはまた、サーバから携帯電話のウェブブラウザにネットワークを介して送信され、そのウェブブラウザによって実行される、ＨＴＭＬ（HyperText Markup Language）などのプログラミング言語により記述されたコンピュータプログラムであってもよい。 The computer program according to the present embodiment may be, for example, a smartphone application program downloaded from a smartphone application download site on the Internet, or alternatively, from a server to a mobile phone web browser via a network. Or a computer program written in a programming language such as HTML (HyperText Markup Language) that is transmitted by the web browser and executed by the web browser.
図１は、本実施の形態に係るコンピュータプログラムを実行するスマートホンにおける一連の処理の一例を示すフローチャートである。スマートホンは、ハンドオーバが発生するたびに、ＧＰＳ（Global Positioning System）などの測位システムを使用した測位処理を実行する。 FIG. 1 is a flowchart showing an example of a series of processes in a smartphone that executes a computer program according to the present embodiment. Each time a handover occurs, the smart phone performs a positioning process using a positioning system such as GPS (Global Positioning System).
スマートホンは、ハンドオーバが発生したか否かを判定する（Ｓ２０２）。ハンドオーバが発生していないと判定された場合（Ｓ２０２のＮ）、スマートホンは所定期間待機し（Ｓ２０６）、処理はステップＳ２０２に戻る。 The smart phone determines whether a handover has occurred (S202). If it is determined that a handover has not occurred (N in S202), the smartphone waits for a predetermined period (S206), and the process returns to step S202.
ハンドオーバが発生したと判定された場合（Ｓ２０２のＹ）、スマートホンはＧＰＳを使用した測位処理を実行する（Ｓ２０４）。その後、処理はステップＳ２０２に戻る。 If it is determined that a handover has occurred (Y in S202), the smart phone executes a positioning process using GPS (S204). Thereafter, the process returns to step S202.
本実施の形態に係るコンピュータプログラムによると、ハンドオーバを契機としてＧＰＳ測位が実行される。言い換えると、スマートホンに対応する基地局が変わらないとＧＰＳ自動測位は実行されない。したがって、例えば所定の時間間隔でＧＰＳ測位が実行される場合と比較して、スマートホンの位置があまり変わっていない状況でのＧＰＳ測位の発生が抑制される。その結果、無駄なＧＰＳ測位を抑制して消費電力を低減し、スマートホンの電池の持ちを改善できる。 According to the computer program according to the present embodiment, GPS positioning is executed in response to a handover. In other words, GPS automatic positioning is not executed unless the base station corresponding to the smart phone changes. Therefore, for example, compared with the case where GPS positioning is executed at predetermined time intervals, the occurrence of GPS positioning in a situation where the position of the smart phone has not changed much is suppressed. As a result, useless GPS positioning can be suppressed, power consumption can be reduced, and the battery life of the smartphone can be improved.
また、ハンドオーバが発生する状況では通常、スマートホンの位置もある程度は変わっているので、本実施の形態におけるＧＰＳ自動測位はそれぞれ有益な位置情報すなわち前回の測位結果とは異なる測位結果を提供できる。
以上より、スマートホンにおける消費電力を低減しつつ、スマートホンの現在位置をより的確に自動更新できるコンピュータプログラムが提供される。
Further, since the position of the smart phone is usually changed to some extent in a situation where a handover occurs, the GPS automatic positioning in the present embodiment can provide useful position information, that is, a positioning result different from the previous positioning result.
As described above, a computer program that can automatically update the current position of the smartphone more accurately while reducing the power consumption of the smartphone is provided.
なお、ステップＳ２０４において、ＧＰＳ測位処理の実行中にハンドオーバが発生した場合でも、スマートホンは、実行中のＧＰＳ測位処理を中断ないし停止することなく完了する。例えば新幹線で移動中などユーザが高速で移動中の場合、ハンドオーバーが頻繁に発生し、その発生頻度がＧＰＳ測位にかかる時間よりも短くなることもある。本実施の形態では、そのような場合でもＧＰＳ測位要求同士の干渉を解決することができる。 In step S204, even when a handover occurs during execution of the GPS positioning process, the smartphone completes without interrupting or stopping the GPS positioning process being executed. For example, when the user is moving at a high speed such as moving on the Shinkansen, handovers frequently occur and the frequency of occurrence may be shorter than the time required for GPS positioning. In this embodiment, interference between GPS positioning requests can be solved even in such a case.
以上、実施の形態に係るコンピュータプログラムについて説明した。これらの実施の形態は例示であり、それらの各構成要素や各処理の組み合わせにいろいろな変形例が可能なこと、またそうした変形例も本発明の範囲にあることは当業者に理解されるところである。 The computer program according to the embodiment has been described above. These embodiments are exemplifications, and it is understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements and processes, and such modifications are also within the scope of the present invention. is there.
