Can be provided.

以下、図面を参照して本発明の実施の形態を説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は、本発明の第１の実施形態に係る通信方式選択装置１の構成を表すブロック図である。同図に示す通信方式選択装置１は、加入者回線である加入電話回線３に接続されており、この加入電話回線３が利用可能かどうかを常時監視している通信手段１１と、通信方式の識別および選択を行う通信方式選択手段１３とを少なくとも有する。   FIG. 1 is a block diagram showing a configuration of a communication method selection apparatus 1 according to the first embodiment of the present invention. A communication system selection device 1 shown in the figure is connected to a subscriber telephone line 3 as a subscriber line, and a communication means 11 that constantly monitors whether the subscriber telephone line 3 is available, It has at least communication system selection means 13 for performing identification and selection.

図１に示した通信方式選択装置１は、前述した各手段に加えて、さらに加入電話回線３を介してアナログ音声通話、VoIP（Voice over IP）等の複数の通信方式からの信号を受信する場合、この受信した信号を識別する識別情報を通信方式選択手段１３に送信して、その信号を送信する通信方式の識別および選択を要求する監視手段１２と、予め設定された利用可能な通信方式を記憶する通信方式記憶手段１４と、予め設定された通信方式の使用優先順位を記憶する優先順位記憶手段１５とを有する。   1 receives signals from a plurality of communication systems such as analog voice call and VoIP (Voice over IP) via the subscriber telephone line 3 in addition to the above-described means. In this case, the identification information for identifying the received signal is transmitted to the communication method selection means 13, and the monitoring means 12 for requesting identification and selection of the communication method for transmitting the signal, and a preset available communication method. Communication system storage means 14 for storing the priority, and priority order storage means 15 for storing the use priority order of the communication system set in advance.

なお、通信方式選択装置１は中央処理装置やメインメモリを備えたコンピュータから構成されており、以下説明する各種処理を実行する上で必要なプログラムが保存されている。このプログラムは、例えばＣＤ−ＲＯＭ等のコンピュータ読み取り可能な記録媒体に記録されている。   The communication method selection device 1 is composed of a central processing unit and a computer having a main memory, and stores programs necessary for executing various processes described below. This program is recorded on a computer-readable recording medium such as a CD-ROM.

また、通信方式選択装置１の形態としては、前述した構成を有する単一の専用装置から成り、電話機等の端末に接続される場合と、その構成を電話機内に具備した場合とがあるが、いずれの場合にも同様の効果を得ることができるのは勿論である。   In addition, as a form of the communication method selection device 1, there are a case where it is composed of a single dedicated device having the above-described configuration and is connected to a terminal such as a telephone, and a case where the configuration is provided in the telephone. Of course, the same effect can be obtained in either case.

以上の構成を有する通信方式選択装置１について、まず着信時の通信方式選択装置１の動作を説明する。   Regarding the communication method selection apparatus 1 having the above configuration, the operation of the communication method selection apparatus 1 at the time of incoming will be described first.

通信手段１１が着信信号を受信すると、監視手段１２が受話器を上げることにより生じるオフフック信号を感知し、着信した通信方式の識別を通信方式選択手段１３に要求する。   When the communication means 11 receives the incoming signal, the monitoring means 12 senses an off-hook signal generated by raising the handset, and requests the communication method selection means 13 to identify the incoming communication method.

着信した通信方式を識別するための識別情報として監視手段１２が通信方式識別手段１３に送信するものとしては、通信方式固有の情報を与えることのできるものであればよい。例えば、通信方式によって使用される信号ごとに周波数帯域を決めておき、着信時にどの周波数帯域の信号を受信したかを識別情報として用いることができる。   As the identification information for identifying the incoming communication system, the monitoring unit 12 may transmit information specific to the communication system to the communication system identification unit 13 as long as the information can be given to the communication system. For example, it is possible to determine a frequency band for each signal used according to the communication method and use as identification information which frequency band the signal is received at the time of incoming call.

この他にも、各通信方式に対応するプロトコルを決めておき、着信した信号に係るプロトコルの情報（ヘッダ情報等）を用いてもよいし、ISDN（Integrated Services Digital Network）の基本インタフェースにおけるパケットデータ用チャネル（Ｄチャネル）のように、通信方式別に送信される固有の制御信号を識別情報として用いることもできる。   In addition to this, a protocol corresponding to each communication method may be determined, and protocol information (header information, etc.) relating to an incoming signal may be used, or packet data in the basic interface of ISDN (Integrated Services Digital Network) A unique control signal transmitted for each communication method, such as a communication channel (D channel), can also be used as identification information.

上記以外にも、各信号に対応して通信回線に供給される電圧の値や、信号ごとに定められた周波数合成信号、あるいは信号の一定時間における極性反転数などを識別情報として用いることも可能である。   In addition to the above, it is also possible to use the value of the voltage supplied to the communication line corresponding to each signal, the frequency synthesized signal determined for each signal, or the number of polarity inversions of the signal for a certain time as identification information It is.

本実施形態においては、上述したいずれの識別情報を用いたとしても同様の効果が得られるのはいうまでもない。   In the present embodiment, it goes without saying that the same effect can be obtained even if any of the identification information described above is used.

識別情報を受信した通信方式選択手段１３は、予め使用可能な通信方式を記憶した通信方式記憶手段１４の情報と、予め設定された各通信方式の使用優先順位を記憶した優先順位記憶手段１５の情報とに基づいて着信した通信方式の識別を行い、その結果を監視手段１２に送信する。   The communication method selection unit 13 that has received the identification information stores information on the communication method storage unit 14 that stores a communication method that can be used in advance, and a priority order storage unit 15 that stores a preset use priority of each communication method. The incoming communication method is identified based on the information, and the result is transmitted to the monitoring means 12.

この結果を受信した監視手段１２は、着信した通信方式に基づいて通信を行うよう通信手段１１に要求し、通信手段１１が着信した通信方式に従って通信を行う。   Upon receiving this result, the monitoring unit 12 requests the communication unit 11 to perform communication based on the incoming communication method, and performs communication according to the communication method that the communication unit 11 has received.

次に、使用している通信方式での通信が困難になったときに通信方式の変更を行う場合の通信方式選択装置１の動作について説明する。   Next, the operation of the communication method selection apparatus 1 when the communication method is changed when communication using the communication method being used becomes difficult will be described.

この場合、通信回線自身が利用可能かどうかを常時監視している通信手段１１が、監視手段１２に対して現在使用中の通信回線以外の通信方式を依頼し、監視手段１２はこの依頼を受けて、どの通信方式に変更するかの選択を通信方式選択手段１３に要求する。   In this case, the communication means 11 constantly monitoring whether the communication line itself is available requests the monitoring means 12 for a communication method other than the communication line currently in use, and the monitoring means 12 receives this request. Thus, the communication method selection unit 13 is requested to select which communication method to change to.

通信方式選択手段１３は、通信方式記憶手段１４の情報と優先順位記憶手段１５の情報とに基づいて変更する通信方式を決定する。   The communication method selection unit 13 determines the communication method to be changed based on the information in the communication method storage unit 14 and the information in the priority order storage unit 15.

この決定結果を受信した監視手段１２は、通信方式変更通知が相手端末に着信し、接続が成立したことを確認するまでは現状の通信方式を維持し、接続成立後新通信方式に通信を変更し、それまで使用していた通信方式については切断するよう通信手段１１へ通知する。   The monitoring unit 12 that has received the determination result maintains the current communication method until the communication method change notification arrives at the partner terminal and confirms that the connection has been established, and changes the communication to the new communication method after the connection is established. Then, the communication unit 11 is notified to disconnect the communication method used so far.

以上説明した本発明の第１の実施形態によれば、使用可能な通信方式をその優先順位とともに記憶しておくことにより、通信状況の変化に即して最適な通信方式を自動的に選択することが可能になる。   According to the first embodiment of the present invention described above, the optimum communication method is automatically selected according to the change in the communication status by storing the usable communication methods together with the priority order. It becomes possible.

図２は、本発明の第２の実施形態に係る通信方式選択装置２の構成を表すブロック図である。同図に示す通信方式選択装置２は、図１に示した通信方式選択装置１に具備された各手段に加え、外部から通信方式を任意に設定することのできる通信方式入力手段２６を有するものである。   FIG. 2 is a block diagram showing the configuration of the communication method selection apparatus 2 according to the second embodiment of the present invention. The communication system selection device 2 shown in the figure has a communication system input means 26 that can arbitrarily set a communication system from the outside in addition to each means provided in the communication system selection device 1 shown in FIG. It is.

なお、通信方式選択装置１と同じ名称の各手段の機能については通信方式選択装置１と同じであり、それらについては図２で示す各手段の符号の下１桁が、図１で対応する手段を示す符号の下１桁と揃うように表示してある。   Note that the function of each means having the same name as that of the communication method selection apparatus 1 is the same as that of the communication method selection apparatus 1, and for these, the last one digit of each means shown in FIG. It is displayed so as to be aligned with the last digit of the sign indicating.

以上の構成を有する通信方式選択装置２の動作において、上記通信方式選択装置１の動作と異なる点は、通信方式選択手段２３がどの通信方式に変更するかの決定を行う際、通信方式入力手段２６により外部から入力されて設定された通信方式がある場合には、この情報と通信方式記憶手段２４に記憶された通信方式に関する情報とに基づいて最適な通信方式を決定する点である。   The operation of the communication method selection device 2 having the above configuration is different from the operation of the communication method selection device 1 in that when the communication method selection unit 23 determines which communication method to change, the communication method input unit In the case where there is a communication system that is input and set from the outside by H.26, the optimum communication system is determined based on this information and information related to the communication system stored in the communication system storage means 24.

この結果、通信方式選択装置２においては、通信方式選択装置１と同様の効果が得られることに加え、通信時の状況に応じて利用者が変更を希望する通信方式を通信方式入力手段により適宜選択することが可能になる。   As a result, in the communication method selection device 2, in addition to obtaining the same effect as the communication method selection device 1, the communication method that the user desires to change according to the situation at the time of communication is appropriately selected by the communication method input means. It becomes possible to select.

図３は、上述した通信方式選択装置２同士が通信を行っている場合の構成を表すブロック図である。以下では通信網７を介して通信を行う二つの通信方式選択装置２を区別するために、それぞれＡ、Ｂを符号に付与して通信方式選択装置２Ａ、２Ｂと称する。なお、各装置を構成する通信手段２１を始めとした各手段についてもこれに準じ、手段を表記する符号にそれぞれＡ、Ｂを付け加えることとする。   FIG. 3 is a block diagram showing a configuration when the above-described communication method selection devices 2 are communicating with each other. Below, in order to distinguish the two communication system selection apparatuses 2 which communicate via the communication network 7, A and B are attached | subjected to a code | symbol and are called communication system selection apparatuses 2A and 2B, respectively. It should be noted that each means including the communication means 21 constituting each device is similarly added with A and B added to the reference numerals representing the means.

図４は、図３に示した二つの通信方式選択装置２Ａおよび２Ｂが、通信中に通信方式を変更するときの信号の流れを表すシーケンス図である。   FIG. 4 is a sequence diagram showing a signal flow when the two communication method selection devices 2A and 2B shown in FIG. 3 change the communication method during communication.

この場合、通信の開始時、または途中で通信方式変更通知を相手側の通信方式選択装置に送信することにより随時通信方式を変更することが可能となる。   In this case, it is possible to change the communication method at any time by transmitting a communication method change notification to the communication method selection device on the other side at the start of communication or during the communication.

以後、便宜上通信方式の変更を最初に通知する側の通信方式選択装置を２Ｂ、この通信方式選択装置２Ｂから通信方式の変更通知を受信する側の通信方式選択装置を２Ａと称する。   Hereinafter, for convenience, the communication method selection device that first notifies the communication method change is referred to as 2B, and the communication method selection device that receives the communication method change notification from the communication method selection device 2B is referred to as 2A.

通信選択装置２Ｂは、通信中の通信選択装置２Ａに対して通信手段２１Ｂによって通信方式変更依頼通知を送信する（ステップｄ１）。   The communication selection device 2B transmits a communication method change request notification by the communication means 21B to the communication selection device 2A in communication (step d1).

通信方式選択装置２Ｂから通信方式変更通知を受信した通信手段２１Ａは、監視手段２２Ａに対して、現在使用している通信方式（以後、通信方式１と称する）以外で使用可能な通信方式の選択を依頼し、監視手段２２Ａはどの通信方式で通信を行うことが可能か選択するよう通信方式選択手段２３Ａに要求する。   The communication unit 21A that has received the communication mode change notification from the communication mode selection device 2B selects a communication mode that can be used for a monitoring unit 22A other than the currently used communication mode (hereinafter referred to as communication mode 1). The monitoring unit 22A requests the communication method selection unit 23A to select which communication method is used for communication.

通信方式選択手段２３Ａは、通信方式記憶手段２４Ａおよび優先順位記憶手段２５Ａの情報と、受信した通信方式変更通知とに基づいて利用可能な通信方式を選択し、その結果を監視手段２２Ａに送信する。   The communication method selection unit 23A selects an available communication method based on the information in the communication method storage unit 24A and the priority order storage unit 25A and the received communication method change notification, and transmits the result to the monitoring unit 22A. .

選択された通信方式は、その後監視手段２２Ａから通信手段２１Ａを介して通信方式選択装置２３Ｂに送信される（ステップｄ３）。   The selected communication method is then transmitted from the monitoring unit 22A to the communication method selection device 23B via the communication unit 21A (step d3).

通信方式選択装置２Ｂは、通信方式選択装置２Ａから受信した利用可能な通信方式の情報に基づいて、通信方式記憶手段２４Ｂおよび優先順位記憶手段２５Ｂを用いて変更する通信方式を決定し、決定した通信方式（以後、通信方式２と称する）を通信方式選択装置２Ａに通知することにより、通信方式変更予約を行う（ステップｄ５）。   The communication method selection device 2B determines the communication method to be changed using the communication method storage unit 24B and the priority order storage unit 25B based on the information on the available communication method received from the communication method selection device 2A. A communication system change reservation is made by notifying the communication system selection device 2A of the communication system (hereinafter referred to as communication system 2) (step d5).

通信方式選択装置２Ａは通信方式２への変更予約通知を受信して、予約完了通知を通信方式選択装置２Ｂに送信する（ステップｄ７）。   The communication method selection device 2A receives the notification of reservation for changing to the communication method 2, and transmits a reservation completion notification to the communication method selection device 2B (step d7).

通信方式選択装置２Ｂは、通信方式２により通信方式選択装置２Ａへの接続を試みる（ステップｄ９）。   The communication method selection device 2B tries to connect to the communication method selection device 2A by the communication method 2 (step d9).

接続要求を受けた通信方式選択装置２Ａは、通信方式２による接続が成立した時点で接続成立が完了したことを通知する接続完了通知を通信方式選択装置２Ｂに送信する（ステップｄ１１）。   Receiving the connection request, the communication method selection device 2A transmits a connection completion notification notifying that the connection establishment is completed at the time when the connection by the communication method 2 is established to the communication method selection device 2B (step d11).

通信方式選択装置２Ｂは、接続完了通知を受信すると、新たに接続した通信方式２で通信を開始するとともに、それまで用いていた通信方式１の切断要求を通信方式選択装置２Ａへ送信する（ステップｄ１３）。   Upon receiving the connection completion notification, the communication method selection device 2B starts communication with the newly connected communication method 2, and transmits a disconnection request for the communication method 1 used so far to the communication method selection device 2A (step S2). d13).

通信方式選択装置２Ａは、受信した切断要求に基づき、通信方式１を通信手段２１Ａによって切断する。   The communication method selection device 2A disconnects the communication method 1 by the communication means 21A based on the received disconnection request.

以上により、通信方式１から通信方式２への変更が、通信を中断することなく完了する。   As described above, the change from the communication method 1 to the communication method 2 is completed without interrupting the communication.

図４を用いて説明した上記通信方式選択装置同士の通信方式変更処理によれば、新たに選択された通信方式への接続が確認されるまでは現状の通信方式を維持し、接続確認が終了後に新通信方式へ移行するとともに現通信方式を切断することで、利用者が通信時に最適な通信方式を用いた通信を行うことが可能となる。   According to the communication method change process between the communication method selection devices described with reference to FIG. 4, the current communication method is maintained until the connection to the newly selected communication method is confirmed, and the connection confirmation is completed. By switching to the new communication method later and disconnecting the current communication method, the user can perform communication using the optimal communication method during communication.

なお、ここでは通信方式選択装置２を用いた場合につき説明したが、通信方式選択装置１を用いても同様の効果を得ることができるのは言うまでもない。   Although the case where the communication method selection device 2 is used has been described here, it is needless to say that the same effect can be obtained even when the communication method selection device 1 is used.

以上説明した本発明の第２の実施形態によれば、上記第１の実施形態と同様の効果が得られることに加え、通信時の状況に応じて利用者が変更を希望する通信方式を適宜選択することが可能になる。   According to the second embodiment of the present invention described above, in addition to obtaining the same effects as those of the first embodiment, the communication method that the user desires to change according to the communication situation is appropriately selected. It becomes possible to select.

また、本実施形態によれば、特に通信方式選択装置同士の通信中に通信方式を変更する際、新たに選択された通信方式への接続が確認されるまでは現状の通信方式を維持し、接続確認が終了後に新通信方式へ移行するとともに現通信方式を切断することにより、利用者が最適な通信環境を有する通信方式に随時変更することが可能となる。   Further, according to the present embodiment, particularly when changing the communication method during communication between communication method selection devices, the current communication method is maintained until the connection to the newly selected communication method is confirmed, By shifting to the new communication method after the connection confirmation is completed and disconnecting the current communication method, the user can change to a communication method having an optimal communication environment at any time.

以上説明した本発明によれば、加入者回線を介して通信を行う複数の通信方式から最適な通信環境を有する通信方式を随時選択することができる通信方式選択方法、通信方式選択装置、通信方式選択プログラムを提供することができる。   According to the present invention described above, a communication method selection method, a communication method selection device, and a communication method capable of selecting a communication method having an optimal communication environment at any time from a plurality of communication methods performing communication via a subscriber line. A selection program can be provided.

また、本発明によれば、複数の通信方式をサポートした通信方式選択装置を用いることにより、通信コスト、通信品質、および通信時のセキュリティを重視した通信を利用者が選択して利用できるようになる。   In addition, according to the present invention, by using a communication method selection device that supports a plurality of communication methods, a user can select and use communication that emphasizes communication cost, communication quality, and security during communication.
