Description

情報処理装置および情報処理装置と通信端末との自動接続方法Information processing apparatus and method for automatically connecting information processing apparatus and communication terminal
　本発明は、通信端末と連携可能な情報処理装置に関し、特に、情報処理装置と通信端末とを自動接続する技術に関する。 The present invention relates to an information processing apparatus capable of cooperating with a communication terminal, and particularly to a technology for automatically connecting the information processing apparatus and the communication terminal.

　例えば、通信端末と連携可能なカーナビゲーション装置には、起動時に、予め登録された通信端末（以下「登録端末」という）に自動接続する機能が搭載されている。一般的なカーナビゲーション装置は、起動時に、登録端末が周囲（車内）に存在するかどうかを確認することなく優先度の最も高い登録端末との接続を試み、接続を確立できずにタイムアウトになると、その登録端末が周囲に存在しないと判断して、その次に優先度の高い別の登録端末との接続を試みる、という動作を繰り返す。そのため、カーナビゲーション装置の周囲に優先度の高い登録端末が存在しない場合には、接続可能な通信端末が見つかるまでの待ち時間が長くなり、その結果、通信端末との接続が確立するまでの時間が長くなる。 For example, a car navigation device that can work with a communication terminal is equipped with a function that automatically connects to a pre-registered communication terminal (hereinafter referred to as "registered terminal") when it is started. When a general car navigation device starts up, it tries to connect to the registration terminal with the highest priority without checking whether the registration terminal exists in the surroundings (inside the car), and if the connection cannot be established and it times out. The operation of determining that the registered terminal does not exist in the surroundings and attempting to connect with another registered terminal having the next highest priority is repeated. Therefore, if there is no registered terminal with high priority around the car navigation device, the waiting time until a connectable communication terminal is found becomes long, and as a result, the time until the connection with the communication terminal is established. Becomes longer.
　本発明は以上のような課題を解決するためになされたものであり、通信端末と連携可能な情報処理装置において、通信端末との自動接続により接続が確立するまでの時間を短くすることを目的とする。 The present invention has been made to solve the above problems, and an object of the present invention is to shorten the time until the connection is established by the automatic connection with the communication terminal in the information processing apparatus capable of cooperating with the communication terminal. And
　本発明に係る情報処理装置は、通信端末と連携可能な情報処理装置であって、第１の通信方式の通信を用いて、通信端末との連携のための接続を確立する接続処理部と、連携が許可される通信端末およびその通信端末の優先度が登録された登録端末リストを記憶する登録端末記憶部と、一定間隔でブロードキャスト送信が行われる第２の通信方式の通信を用いて、情報処理装置の周囲に存在する通信端末を検出する通信端末検出部と、登録端末リストに登録された通信端末のうち、通信端末検出部により検出された通信端末の優先度を上げる優先度管理部と、接続処理部に、登録端末リストに登録された通信端末との接続を、優先度の高い通信端末から順に試みさせる自動接続制御部と、を備える。 An information processing apparatus according to the present invention is an information processing apparatus capable of cooperating with a communication terminal, and uses a communication of the first communication method, and a connection processing unit that establishes a connection for cooperating with the communication terminal, Information is obtained by using a registered terminal storage unit that stores a registered terminal list in which the communication terminals permitted to cooperate and the priority of the communication terminal are registered, and communication of the second communication method in which broadcast transmission is performed at regular intervals. A communication terminal detection unit that detects a communication terminal existing around the processing device, and a priority management unit that raises the priority of the communication terminal detected by the communication terminal detection unit among the communication terminals registered in the registered terminal list. The connection processing unit is provided with an automatic connection control unit that causes the communication terminals registered in the registered terminal list to be tried in order from the communication terminal having the highest priority.
　本発明によれば、登録端末リストに登録された通信端末のうち、情報処理装置の周囲に存在する通信端末の優先度が高くなるため、周囲に存在しない通信端末との接続が試みられることが防止され、通信端末との接続が確立するまでの時間が短縮化される。 According to the present invention, among the communication terminals registered in the registered terminal list, the communication terminals existing in the vicinity of the information processing apparatus have higher priority, so that connection with a communication terminal not existing in the vicinity may be attempted. It is prevented, and the time until the connection with the communication terminal is established is shortened.
　本発明の目的、特徴、態様、および利点は、以下の詳細な説明と添付図面とによって、より明白となる。 The objects, features, aspects and advantages of the present invention will become more apparent by the following detailed description and the accompanying drawings.

　図１は、本発明の実施の形態に係る情報処理装置１０の構成を示すブロック図である。情報処理装置１０は、通信端末１との通信を行うことによって、通信端末１と連携した動作が可能な機器である。情報処理装置１０の種類には制約はなく、情報処理装置１０としては、例えば、パーソナルコンピュータ、カーナビゲーション装置などが考えられる。通信端末１の種類にも制約はないが、ここでは、通信端末１は、携帯電話やスマートフォン、タブレット端末など、携帯型の通信機器であるものとする。 FIG. 1 is a block diagram showing the configuration of the information processing device 10 according to the embodiment of the present invention. The information processing device 10 is a device that can operate in cooperation with the communication terminal 1 by communicating with the communication terminal 1. There are no restrictions on the type of the information processing device 10, and examples of the information processing device 10 include a personal computer and a car navigation device. Although there is no restriction on the type of the communication terminal 1, it is assumed here that the communication terminal 1 is a portable communication device such as a mobile phone, a smartphone, or a tablet terminal.
　通信端末１および情報処理装置１０は、近距離無線通信として、第１の通信方式による通信と、第２の通信方式による通信とを行う機能を有している。第１の通信方式の種類には制約はなく、例えばBluetooth、無線ＬＡＮ（Local Area Network）などを用いることができる。第２の通信方式は、一定間隔でブロードキャスト送信が行われるものであり、その具体例としては、Bluetooth Low Energy（ＢＬＥ）などがある。本実施の形態では、第１の通信方式は、Bluetoothの通信方式であり、第２の通信方式は、Bluetooth Low Energyの通信方式であるものとする。以下、Bluetoothを「ＢＴ」、Bluetooth Low Energyを「ＢＬＥ」と略称する。 The communication terminal 1 and the information processing device 10 have a function of performing communication by the first communication method and communication by the second communication method as short-range wireless communication. There is no restriction on the type of the first communication method, and for example, Bluetooth, wireless LAN (Local Area Network), or the like can be used. The second communication method is that broadcast transmission is performed at regular intervals, and a specific example thereof is Bluetooth Low Energy (BLE). In the present embodiment, the first communication method is the Bluetooth communication method, and the second communication method is the Bluetooth Low Energy communication method. Hereinafter, Bluetooth is abbreviated as “BT” and Bluetooth Low Energy is abbreviated as “BLE”.
　ＢＬＥは、ＢＴの拡張規格の一つであり、一定間隔で任意の情報をブロードキャスト送信する「ビーコン」と呼ばれる機能を備えている。ビーコン機能で送信された信号（以下「ビーコン信号」という）は、ブロードキャスト送信されるため、事前のペアリング無しに、周辺の機器が受信することができる。また、ＢＬＥ通信は通常のＢＴ通信よりも消費電力が低いという利点もある。ＢＬＥのビーコン信号には、その送信元の通信端末１を識別するための識別子として、送信元の通信端末１のＭＡＣアドレス（Media Access Control address）の情報が含まれている。 BLE is an extended standard of BT, and has a function called "beacon" that broadcasts arbitrary information at regular intervals. Since the signal transmitted by the beacon function (hereinafter referred to as “beacon signal”) is broadcast-transmitted, peripheral devices can receive the signal without prior pairing. In addition, BLE communication has an advantage that it consumes less power than normal BT communication. The BLE beacon signal includes information on the MAC address (Media Access Control address) of the communication terminal 1 of the transmission source as an identifier for identifying the communication terminal 1 of the transmission source.
　図１に示すように、情報処理装置１０は、接続処理部１１、登録端末記憶部１２、通信端末検出部１３、優先度管理部１４および自動接続制御部１５を備えている。 As shown in FIG. 1, the information processing device 10 includes a connection processing unit 11, a registration terminal storage unit 12, a communication terminal detection unit 13, a priority management unit 14, and an automatic connection control unit 15.
　接続処理部１１は、第１の通信方式の通信（ＢＴ通信）を用いて、通信端末１との連携のための接続を確立する処理を行う。情報処理装置１０は複数の通信端末１との連携が可能であるが、セキュリティの観点から、連携が許可される通信端末１は予め情報処理装置１０に登録されたものに制限される。 The connection processing unit 11 performs processing for establishing a connection for cooperation with the communication terminal 1 by using the communication of the first communication method (BT communication). The information processing device 10 can cooperate with a plurality of communication terminals 1, but from the viewpoint of security, the communication terminals 1 that are permitted to cooperate are limited to those registered in the information processing device 10 in advance.
　登録端末記憶部１２は、情報処理装置１０との連携が許可される通信端末１が登録されたリストを記憶する記憶媒体である。当該リストには、情報処理装置１０との連携が許可される通信端末１の識別子と、その通信端末１の優先度とが登録される。本実施の形態では、当該リストに登録される通信端末１の識別子として、ＭＡＣアドレスを用いる。以下、当該リストに登録されている通信端末１を「登録端末」といい、当該リストを「登録端末リスト」という。 The registration terminal storage unit 12 is a storage medium that stores a list in which the communication terminals 1 that are permitted to cooperate with the information processing apparatus 10 are registered. The identifier of the communication terminal 1 permitted to cooperate with the information processing apparatus 10 and the priority of the communication terminal 1 are registered in the list. In this embodiment, the MAC address is used as the identifier of the communication terminal 1 registered in the list. Hereinafter, the communication terminal 1 registered in the list is referred to as a “registered terminal”, and the list is referred to as a “registered terminal list”.
　登録端末リストに通信端末１を登録する方法としては、ユーザの操作によって情報処理装置１０とペアリングされた通信端末１のＭＡＣアドレスが自動的に登録端末リストに登録されるようにする方法や、登録したい通信端末１のＭＡＣアドレスをユーザが手入力する方法などが考えられる。また、登録端末の優先度の設定方法としては、接続履歴が新しい登録端末から順に優先度を高くする方法などが考えられるが、例えば、ユーザが「お気に入り端末」として指定した登録端末の優先度を常に最上位（１位）としてもよい。 As a method of registering the communication terminal 1 in the registration terminal list, a method of automatically registering the MAC address of the communication terminal 1 paired with the information processing device 10 by a user operation in the registration terminal list, A method in which the user manually inputs the MAC address of the communication terminal 1 to be registered can be considered. Further, as a method of setting the priority of the registered terminal, a method of increasing the priority in order from the registered terminal having the newest connection history can be considered. For example, the priority of the registered terminal designated by the user as a “favorite terminal” can be set. It may be always at the top (1st).
　通信端末検出部１３は、一定間隔でブロードキャスト送信が行われる第２の通信方式の通信（ＢＬＥ通信）を用いて、情報処理装置１０の周囲に存在する通信端末１を検出する。具体的には、通信端末検出部１３は、通信端末１から送信されるビーコン信号を受信することで、その送信元である通信端末１が情報処理装置１０の周囲に存在すると判断する。ここでいう「情報処理装置１０の周囲」は、情報処理装置１０とのＢＴ通信が可能な範囲と同等、あるいはそれよりも狭い範囲であることが好ましい。よって、情報処理装置１０とのＢＬＥ通信が可能な範囲は、情報処理装置１０とのＢＴ通信が可能な範囲と同等、あるいはそれよりも狭い範囲に設定されることが好ましい。 The communication terminal detection unit 13 detects the communication terminals 1 existing around the information processing apparatus 10 by using the second communication method communication (BLE communication) in which broadcast transmission is performed at regular intervals. Specifically, the communication terminal detection unit 13 receives the beacon signal transmitted from the communication terminal 1, and determines that the communication terminal 1 that is the transmission source exists around the information processing device 10. The “surroundings of the information processing device 10” here are preferably equal to or narrower than the range in which BT communication with the information processing device 10 is possible. Therefore, it is preferable that the range in which the BLE communication with the information processing device 10 is possible is set to be equal to or narrower than the range in which the BT communication with the information processing device 10 is possible.
　また、通信端末検出部１３は、受信したビーコン信号に含まれるＭＡＣアドレスと、登録端末記憶部１２に記憶された登録端末リストに登録されている通信端末１（登録端末）のＭＡＣアドレスとを照合することで、情報処理装置１０の周囲に存在する通信端末１が登録端末であるか否かを判断することができる。 In addition, the communication terminal detection unit 13 collates the MAC address included in the received beacon signal with the MAC address of the communication terminal 1 (registered terminal) registered in the registered terminal list stored in the registered terminal storage unit 12. By doing so, it is possible to determine whether or not the communication terminal 1 existing around the information processing device 10 is a registered terminal.
　優先度管理部１４は、登録端末リストに登録された通信端末１（登録端末）の優先度を管理する。具体的には、優先度管理部１４は、通信端末検出部１３によって情報処理装置１０の周囲に存在する登録端末が検出された場合に、その登録端末の優先度を上げて、登録端末リストを更新する。また、優先度管理部１４は、優先度を上げた登録端末が、通信端末検出部１３により検出されなくなった場合に、その登録端末の優先度を元の優先度（通信端末検出部１３に検出される前の優先度）に戻し、登録端末リストを更新する。 The priority management unit 14 manages the priority of the communication terminal 1 (registered terminal) registered in the registered terminal list. Specifically, when the communication terminal detection unit 13 detects a registered terminal existing around the information processing device 10, the priority management unit 14 raises the priority of the registered terminal and displays the registered terminal list. Update. Further, when the communication terminal detecting unit 13 no longer detects the registered terminal whose priority has been raised, the priority managing unit 14 detects the priority of the registered terminal as the original priority (the communication terminal detecting unit 13 detects the priority). (Priority before) is updated and the registered terminal list is updated.
　優先度管理部１４が周囲に存在する登録端末の優先度を上げるとき、当該登録端末の優先度を最上位まで上げることが好ましい。ただし、ユーザが設定した「お気に入り端末」が存在する場合、優先度管理部１４は、周囲に存在する登録端末の優先度を、「お気に入り端末」の次の順位まで上げるようにしてもよい。 When the priority management unit 14 raises the priority of registered terminals existing in the surroundings, it is preferable to raise the priority of the registered terminals to the highest level. However, when there is a “favorite terminal” set by the user, the priority management unit 14 may increase the priority of registered terminals existing in the vicinity to the next rank of the “favorite terminal”.
　また、情報処理装置１０の周囲に複数の登録端末が検出された場合、優先度管理部１４は、検出された複数の登録端末の優先度を上げる。その場合、それら複数の登録端末における優先関係が、優先度を変更する前後で維持されるようにするとよい。つまり、元の優先度が高い登録端末ほど、より高い優先度まで上げられるようにするとよい。 Further, when a plurality of registered terminals are detected around the information processing apparatus 10, the priority management unit 14 raises the priority of the detected plurality of registered terminals. In that case, the priority relationship between the plurality of registered terminals may be maintained before and after the priority is changed. That is, it is preferable that the higher the original priority of the registered terminal, the higher the priority of the registered terminal.
　自動接続制御部１５は、接続処理部１１を制御して、登録端末リストに登録された通信端末１（登録端末）との自動接続を行う。具体的には、自動接続制御部１５は、接続処理部１１に、第１の通信方式を用いた登録端末との接続を、優先度の高い登録端末から順に試みさせる。本実施の形態では、優先度管理部１４が、情報処理装置１０の周囲に存在する登録端末の優先度を高くするため、周囲に存在しない登録端末との接続が試みられることが防止される。従って、自動接続によって通信端末１との接続が確立するまでの時間が短縮化される。 The automatic connection control unit 15 controls the connection processing unit 11 to automatically connect to the communication terminal 1 (registered terminal) registered in the registered terminal list. Specifically, the automatic connection control unit 15 causes the connection processing unit 11 to try to connect with the registered terminal using the first communication method in order from the registered terminal with the highest priority. In the present embodiment, the priority management unit 14 raises the priority of the registered terminals existing around the information processing apparatus 10, so that an attempt to connect with a registered terminal that does not exist around the information processing apparatus 10 is prevented. Therefore, the time until the connection with the communication terminal 1 is established by the automatic connection is shortened.
　なお、自動接続制御部１５が自動接続を行うタイミングは、典型的には情報処理装置１０の起動時であるが、それに限られない。例えば、情報処理装置１０と接続中の登録端末が情報処理装置１０から遠ざかったり、情報処理装置１０と接続中の登録端末の電源がオフになったりして、情報処理装置１０と登録端末との接続が途絶えた場合にも自動接続が行われてもよい。 The timing at which the automatic connection control unit 15 performs the automatic connection is typically when the information processing apparatus 10 is started, but is not limited thereto. For example, when the registration terminal connected to the information processing apparatus 10 moves away from the information processing apparatus 10 or the registration terminal connected to the information processing apparatus 10 is turned off, the information processing apparatus 10 and the registration terminal are not connected to each other. Automatic connection may be performed even when the connection is lost.
　図２および図３は、本実施の形態に係る情報処理装置１０の動作を示すフローチャートである。図２は、情報処理装置１０が周囲に存在する通信端末１を検出する処理（通信端末検出処理）を示しており、図３は情報処理装置１０が通信端末１との自動接続を行う処理（自動接続処理）を示している。 2 and 3 are flowcharts showing the operation of the information processing device 10 according to the present embodiment. FIG. 2 shows a process (communication terminal detection process) in which the information processing device 10 detects a communication terminal 1 existing around, and FIG. 3 shows a process in which the information processing device 10 automatically connects to the communication terminal 1 ( Automatic connection processing).
　まず、図２を参照し、通信端末検出処理について説明する。情報処理装置１０が起動すると、通信端末検出部１３は、第２の通信方式の通信（ＢＬＥ通信）を用いて、情報処理装置１０の周囲に存在する通信端末１から送信されるビーコン信号を受信する（ステップＳ１０１）。そして、通信端末検出部１３は、受信したビーコン信号に含まれるＭＡＣアドレスと、登録端末記憶部１２に記憶された登録端末リストに登録されている通信端末１（登録端末）のＭＡＣアドレスとを照合することで、情報処理装置１０の周囲に存在する登録端末を検出する（ステップＳ１０２）。 First, the communication terminal detection process will be described with reference to FIG. When the information processing device 10 is activated, the communication terminal detection unit 13 receives the beacon signal transmitted from the communication terminals 1 existing around the information processing device 10 by using the communication (BLE communication) of the second communication method. Yes (step S101). Then, the communication terminal detection unit 13 collates the MAC address included in the received beacon signal with the MAC address of the communication terminal 1 (registration terminal) registered in the registration terminal list stored in the registration terminal storage unit 12. By doing so, the registered terminals existing around the information processing device 10 are detected (step S102).
　続いて、優先度管理部１４は、ステップＳ１０２において情報処理装置１０の周囲に存在する登録端末が新たに検出されたか否かを確認する（ステップＳ１０３）。情報処理装置１０の周囲に存在する登録端末が新たに検出されていれば（ステップＳ１０３でＹＥＳ）、優先度管理部１４は、その登録端末の優先度を高くして、登録端末リストを更新する（ステップＳ１０４）。情報処理装置１０の周囲に存在する登録端末が新たに検出されていなければ（ステップＳ１０３でＮＯ）、ステップＳ１０４はスキップされる。 Subsequently, the priority management unit 14 confirms whether or not a registered terminal existing around the information processing device 10 is newly detected in step S102 (step S103). If a registered terminal existing around the information processing device 10 is newly detected (YES in step S103), the priority management unit 14 increases the priority of the registered terminal and updates the registered terminal list. (Step S104). If a registered terminal existing around the information processing device 10 is not newly detected (NO in step S103), step S104 is skipped.
　さらに、優先度管理部１４は、ステップＳ１０２の検出結果に基づき、情報処理装置１０の周囲から無くなった登録端末が生じたか否かを確認する（ステップＳ１０５）。情報処理装置１０の周囲から無くなった登録端末が生じていれば（ステップＳ１０５でＹＥＳ）、優先度管理部１４は、その登録端末の優先度を元に戻して、登録端末リストを更新する（ステップＳ１０６）。情報処理装置１０の周囲から無くなった登録端末が生じていなければ（ステップＳ１０５でＮＯ）、ステップＳ１０６はスキップされる。 Further, the priority management unit 14 confirms whether or not there is a lost registration terminal from the surroundings of the information processing device 10 based on the detection result of step S102 (step S105). If there is a registration terminal that has disappeared from the surroundings of the information processing device 10 (YES in step S105), the priority management unit 14 restores the priority of the registration terminal and updates the registration terminal list (step S105). S106). If there is no registration terminal lost from the surroundings of the information processing device 10 (NO in step S105), step S106 is skipped.
　情報処理装置１０は、以上の通信端末検出処理を繰り返し実行する。ただし、通信端末検出処理は、情報処理装置１０が通信端末１との自動接続を行うときに実行されればよいため、情報処理装置１０と通信端末１との接続が確立している間は実行されなくてもよい。 The information processing device 10 repeatedly executes the above communication terminal detection processing. However, since the communication terminal detection process may be executed when the information processing apparatus 10 automatically connects to the communication terminal 1, it is executed while the connection between the information processing apparatus 10 and the communication terminal 1 is established. It does not have to be done.
　次に、図３を参照しつつ、自動接続処理について説明する。情報処理装置１０が起動すると、自動接続制御部１５は、変数ｉを１に設定する（ステップＳ２０１）。そして、自動接続制御部１５は、登録端末記憶部１２に記憶されている登録端末リストを参照し、接続処理部１１に、第１の通信方式の通信（ＢＴ通信）を用いて、優先度ｉ位の登録端末との接続（ＢＴ接続）を試みさせる（ステップＳ２０２）。 Next, the automatic connection process will be described with reference to FIG. When the information processing device 10 is activated, the automatic connection control unit 15 sets the variable i to 1 (step S201). Then, the automatic connection control unit 15 refers to the registered terminal list stored in the registered terminal storage unit 12, uses the communication of the first communication method (BT communication) for the connection processing unit 11, and uses the priority i. Access to the registered terminal (BT connection) is tried (step S202).
　ステップＳ２０２の結果、接続処理部１１と登録端末との接続が確立しなければ（ステップＳ２０３でＮＯ）、自動接続制御部１５は、登録端末リストが更新されたか否かを確認する（ステップＳ２０４）。登録端末リストが更新されていなければ（ステップＳ２０４でＮＯ）、変数ｉをインクリメントして（ステップＳ２０５）、ステップＳ２０２へ戻る。登録端末リストが更新されていれば（ステップＳ２０４でＹＥＳ）、変数ｉを１にリセットして（ステップＳ２０６）、ステップＳ２０２へ戻る。 As a result of step S202, if the connection between the connection processing unit 11 and the registered terminal is not established (NO in step S203), the automatic connection control unit 15 confirms whether the registered terminal list has been updated (step S204). .. If the registered terminal list has not been updated (NO in step S204), the variable i is incremented (step S205) and the process returns to step S202. If the registered terminal list has been updated (YES in step S204), the variable i is reset to 1 (step S206), and the process returns to step S202.
　一方、ステップＳ２０２の結果、接続処理部１１と登録端末との接続が確立した場合には（ステップＳ２０３でＹＥＳ）、自動接続制御部１５は、その接続が途絶えるまで待機する（ステップＳ２０７）。例えば、情報処理装置１０との接続が確立した登録端末が情報処理装置１０から遠ざかったり、当該登録端末の電源がオフになったりして、情報処理装置１０と登録端末との接続が途絶えると（ステップＳ２０７でＹＥＳ）、ステップＳ２０１へ戻り、再度、自動接続処理が開始される。 On the other hand, as a result of step S202, when the connection between the connection processing unit 11 and the registered terminal is established (YES in step S203), the automatic connection control unit 15 waits until the connection is broken (step S207). For example, the connection between the information processing device 10 and the registration terminal is lost due to the registration terminal that has established a connection with the information processing device 10 moving away from the information processing device 10 or the power of the registration terminal is turned off ( If YES in step S207), the process returns to step S201, and the automatic connection process is started again.
　なお、ステップＳ２０２においては、接続処理部１１が優先度ｉ位の登録端末に対し、接続を複数回試みること、すなわち接続のリトライを行ってもよい。 Note that in step S202, the connection processing unit 11 may try to make a connection with the registered terminal having the i-th priority a plurality of times, that is, retry the connection.
　また、接続処理部１１が、通信端末１との間で複数の種別の接続を確立することが可能な場合がある。例えば第１の通信方式がBluetoothの場合、情報処理装置１０と通信端末１との間で、ＨＦＰ（Hands-Free Profile）接続と、ＡＶＰ（Audio/Video Profile）接続とが確立されることが想定される。 In some cases, the connection processing unit 11 can establish multiple types of connection with the communication terminal 1. For example, when the first communication method is Bluetooth, it is assumed that an HFP (Hands-Free Profile) connection and an AVP (Audio/Video Profile) connection are established between the information processing device 10 and the communication terminal 1. To be done.
　従来の情報処理装置では、図４のように、情報処理装置から優先度ｉ位の通信端末へＨＦＰ接続を要求して失敗した場合（図４では１回のリトライが行われている）、その後に、同じ通信端末へＡＶＰ接続も要求していた。しかし、ＨＦＰ接続に失敗した通信端末は、ＡＶＰ接続を試みても失敗する可能性が高く、ＡＶＰ接続の試行は、情報処理装置と通信端末との接続が確立するまでの時間が長くなる要因になることが多かった。 In the conventional information processing apparatus, as shown in FIG. 4, when an HFP connection is requested from the information processing apparatus to the communication terminal having the i-th priority and it fails (one retry is performed in FIG. 4), In addition, the same communication terminal was also requested to make an AVP connection. However, a communication terminal that fails in HFP connection is likely to fail even when trying to make an AVP connection, and an attempt to make an AVP connection is a factor in that it takes a long time until the connection between the information processing device and the communication terminal is established. It was often
　そこで、本実施の形態では、自動接続制御部１５は、接続処理部１１に、通信端末１との１つの種別の接続を試みさせて失敗すると、他の種別の接続を試みさせずに、その次に優先度の高い通信端末１との接続を試みさせる。例えば、情報処理装置１０と通信端末１との間で、ＨＦＰ接続とＡＶＰ接続とを確立できる場合、図５のように、情報処理装置１０から優先度ｉ位の通信端末１へＨＦＰ接続を要求して失敗すれば（図５では１回のリトライが行われている）、優先度ｉ位の通信端末１とのＡＶＰ接続を試みることなく、優先度ｉ＋１位の通信端末１とのＨＦＰ接続を試みさせる。失敗する可能性が高い優先度ｉ位の通信端末１とのＡＶＰ接続を試みないことで、接続が確立するまでの時間を短縮化できる。 Therefore, in the present embodiment, the automatic connection control unit 15 causes the connection processing unit 11 to try a connection of one type with the communication terminal 1 and if the connection fails, the automatic connection control unit 15 does not try another type of connection and Next, a connection with the communication terminal 1 having the highest priority is tried. For example, when the HFP connection and the AVP connection can be established between the information processing apparatus 10 and the communication terminal 1, the information processing apparatus 10 requests the HFP connection from the communication terminal 1 having the priority i as shown in FIG. If it fails (one retry is performed in FIG. 5), the HFP connection with the communication terminal 1 having the priority i+1 is made without attempting the AVP connection with the communication terminal 1 having the priority i. Let me try. By not attempting an AVP connection with the communication terminal 1 having the i-th priority, which is highly likely to fail, the time until the connection is established can be shortened.
　図６および図７は、それぞれ情報処理装置１０のハードウェア構成の例を示す図である。図１に示した情報処理装置１０の構成要素の各機能は、例えば図６に示す処理回路５０により実現される。すなわち、情報処理装置１０は、連携が許可される通信端末およびその通信端末の優先度が登録された登録端末リストを記憶し、一定間隔でブロードキャスト送信が行われる第２の通信方式の通信を用いて、情報処理装置の周囲に存在する通信端末を検出し、登録端末リストに登録された通信端末のうち、検出された通信端末の優先度を上げ、第１の通信方式の通信を用いて、登録端末リストに登録された通信端末との接続を、優先度の高い通信端末から順に試みる、ための処理回路５０を備える。処理回路５０は、専用のハードウェアであってもよいし、メモリに格納されたプログラムを実行するプロセッサ（中央処理装置（ＣＰＵ：Central Processing Unit）、処理装置、演算装置、マイクロプロセッサ、マイクロコンピュータ、ＤＳＰ（Digital Signal Processor）とも呼ばれる）を用いて構成されていてもよい。 6 and 7 are diagrams each showing an example of the hardware configuration of the information processing apparatus 10. The functions of the components of the information processing apparatus 10 shown in FIG. 1 are realized by the processing circuit 50 shown in FIG. 6, for example. That is, the information processing apparatus 10 stores a communication terminal permitted to cooperate and a registered terminal list in which the priority of the communication terminal is registered, and uses the communication of the second communication method in which broadcast transmission is performed at regular intervals. Then, the communication terminals existing around the information processing device are detected, the priority of the detected communication terminals among the communication terminals registered in the registered terminal list is increased, and the communication of the first communication method is used. A processing circuit 50 is provided for attempting connection with the communication terminals registered in the registered terminal list in order from the communication terminal having the highest priority. The processing circuit 50 may be dedicated hardware, or may be a processor that executes a program stored in a memory (Central Processing Unit (CPU), processing device, arithmetic device, microprocessor, microcomputer, It may be configured by using a DSP (also called Digital Signal Processor)).
　処理回路５０が専用のハードウェアである場合、処理回路５０は、例えば、単一回路、複合回路、プログラム化したプロセッサ、並列プログラム化したプロセッサ、ＡＳＩＣ（Application Specific Integrated Circuit）、ＦＰＧＡ（Field-Programmable Gate Array）、またはこれらを組み合わせたものなどが該当する。情報処理装置１０の構成要素の各々の機能が個別の処理回路で実現されてもよいし、それらの機能がまとめて一つの処理回路で実現されてもよい。 When the processing circuit 50 is dedicated hardware, the processing circuit 50 includes, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), and an FPGA (Field-Programmable). Gate Array), or a combination of these. Each function of the components of the information processing device 10 may be realized by an individual processing circuit, or those functions may be collectively realized by one processing circuit.
　図７は、処理回路５０がプログラムを実行するプロセッサ５１を用いて構成されている場合における情報処理装置１０のハードウェア構成の例を示している。この場合、情報処理装置１０の構成要素の機能は、ソフトウェア等（ソフトウェア、ファームウェア、またはソフトウェアとファームウェアとの組み合わせ）により実現される。ソフトウェア等はプログラムとして記述され、メモリ５２に格納される。プロセッサ５１は、メモリ５２に記憶されたプログラムを読み出して実行することにより、各部の機能を実現する。すなわち、情報処理装置１０は、プロセッサ５１により実行されるときに、連携が許可される通信端末およびその通信端末の優先度が登録された登録端末リストを記憶する処理と、一定間隔でブロードキャスト送信が行われる第２の通信方式の通信を用いて、情報処理装置の周囲に存在する通信端末を検出する処理と、登録端末リストに登録された通信端末のうち、検出された通信端末の優先度を上げ、第１の通信方式の通信を用いて、登録端末リストに登録された通信端末との接続を、優先度の高い通信端末から順に試みる処理と、が結果的に実行されることになるプログラムを格納するためのメモリ５２を備える。換言すれば、このプログラムは、情報処理装置１０の構成要素の動作の手順や方法をコンピュータに実行させるものであるともいえる。 FIG. 7 shows an example of the hardware configuration of the information processing device 10 when the processing circuit 50 is configured using the processor 51 that executes a program. In this case, the functions of the components of the information processing device 10 are realized by software or the like (software, firmware, or a combination of software and firmware). The software and the like are written as a program and stored in the memory 52. The processor 51 realizes the function of each unit by reading and executing the program stored in the memory 52. That is, when the information processing apparatus 10 is executed by the processor 51, the information processing apparatus 10 performs a process of storing a communication terminal permitted to cooperate and a registered terminal list in which the priority of the communication terminal is registered, and a broadcast transmission at regular intervals. A process of detecting a communication terminal existing around the information processing device by using the communication of the second communication method performed, and a priority of the detected communication terminal among the communication terminals registered in the registered terminal list are set. And a process for attempting to connect to the communication terminals registered in the registered terminal list in order from the communication terminal having the highest priority by using the communication of the first communication method. A memory 52 for storing In other words, it can be said that this program causes a computer to execute the procedure and method of operation of the components of the information processing device 10.
　ここで、メモリ５２は、例えば、ＲＡＭ（Random Access Memory）、ＲＯＭ（Read Only Memory）、フラッシュメモリー、ＥＰＲＯＭ（Erasable Programmable Read Only Memory）、ＥＥＰＲＯＭ（Electrically Erasable Programmable Read Only Memory）などの、不揮発性または揮発性の半導体メモリ、ＨＤＤ（Hard Disk Drive）、磁気ディスク、フレキシブルディスク、光ディスク、コンパクトディスク、ミニディスク、ＤＶＤ（Digital Versatile Disc）およびそのドライブ装置等、または、今後使用されるあらゆる記憶媒体であってもよい。 Here, the memory 52 is, for example, RAM (RandomAccessMemory), ROM (ReadOnlyMemory), flash memory, EPROM (ErasableProgrammableReadOnlyMemory), EEPROM (ElectricallyErasableProgrammableReadOnlyMemory), or the like. Volatile semiconductor memory, HDD (Hard Disk Drive), magnetic disk, flexible disk, optical disk, compact disk, mini disk, DVD (Digital Versatile Disc) and its drive device, or any storage medium used in the future. May be.
　以上、情報処理装置１０の構成要素の機能が、ハードウェアおよびソフトウェア等のいずれか一方で実現される構成について説明した。しかしこれに限ったものではなく、情報処理装置１０の一部の構成要素を専用のハードウェアで実現し、別の一部の構成要素をソフトウェア等で実現する構成であってもよい。例えば、一部の構成要素については専用のハードウェアとしての処理回路５０でその機能を実現し、他の一部の構成要素についてはプロセッサ５１としての処理回路５０がメモリ５２に格納されたプログラムを読み出して実行することによってその機能を実現することが可能である。 The configuration of the functions of the components of the information processing apparatus 10 is realized by either hardware or software, etc., as described above. However, the configuration is not limited to this, and a configuration in which some of the components of the information processing device 10 are realized by dedicated hardware and another of the other components is realized by software or the like may be used. For example, for some of the constituent elements, the function is realized by the processing circuit 50 as dedicated hardware, and for some of the other constituent elements, the processing circuit 50 as the processor 51 executes the program stored in the memory 52. The function can be realized by reading and executing.
