Description

通信システム、通信回線選択方法、及びプログラムCommunication system, communication line selection method, and program
　本発明は、通信システム、通信回線選択方法、及びプログラムに関する。 The present invention relates to a communication system, a communication line selection method, and a program.
　通常、携帯電話などの通信装置では、同一国内の通話と、国を跨る通話とでは、通信料が異なる。一方、複数の通信回線（キャリア）に接続可能な携帯電話が存在する。例えば、発信先がローミングにより、発信元と発信先で異なる通信キャリアとなった場合に、発信元だけでなく発信先でも通信料の請求が発生する場合がある。このように、一般的に、発信元と発信先の位置関係により、携帯電話間の電話通信費や、通信品質、通信速度などが異なる。このように、携帯電話などの通信装置では、現在、利用可能な回線のうち、そのときに利用した場合により利便性の高い（例えば、通信費が安くなる、通信品質が高い、通信速度が速いなど）回線が存在する。 Usually, in communication devices such as mobile phones, communication charges differ between calls within the same country and calls across countries. On the other hand, there are mobile phones that can be connected to a plurality of communication lines (carriers). For example, when the destination is a communication carrier that differs between the source and the destination due to roaming, a communication fee may be charged not only at the source but also at the destination. As described above, generally, the telephone communication cost between mobile phones, communication quality, communication speed, and the like differ depending on the positional relationship between the transmission source and the transmission destination. As described above, in a communication device such as a mobile phone, among the currently available lines, it is more convenient when used at that time (for example, the communication cost is reduced, the communication quality is high, and the communication speed is high). Etc.) A circuit exists.
　例えば、特許文献１には、発呼者が一つの電話番号を使用して複数モード対応の通信端末を呼び出す時、交換局は、各通信方式または事業者の共通のデータベースにアクセスし、位置情報やサービスなどの情報、システム上の条件、発呼者の要求、着呼者の設定などの条件と見比べて、どの通信方式または事業者と接続するかを決定し、選択した通信方式または事業者を使用して通信端末と回線を接続する技術が提案されている。 For example, in Patent Document 1, when a caller calls a communication terminal compatible with a plurality of modes using a single telephone number, the switching center accesses a common database of each communication method or carrier, and location information Information and service information, system conditions, caller request, caller settings, and other conditions to determine which communication method or operator to connect to, and the selected communication method or operator A technique for connecting a communication terminal and a line using a network has been proposed.
　例えば、特許文献２には、サービス会社サーバに経路情報テーブルに接続可能な全ての通信経路を記憶しておき、アクセスポイントやゲートウェイに備えたクライアント装置で、経路選択部により、経路情報テーブルから接続する経路情報を選択し、回線接続部により、選択した経路情報に基づいて通信回線を接続する技術が提案されている。 For example, Patent Document 2 stores all communication paths that can be connected to a path information table in a service company server, and is connected from the path information table by a path selection unit in a client device provided in an access point or gateway. A technology has been proposed in which route information to be selected is selected and a communication line is connected by a line connection unit based on the selected route information.
　例えば、特許文献３には、サービス制御装置が、通話料金に応じて、加入者が契約している複数の通信事業者の中から１つを選択し、この選択された通信事業者の回線を介して、発信者を加入者に接続する処理を行なう技術が提案されている。 For example, in Patent Document 3, the service control device selects one of a plurality of communication carriers with which the subscriber has a contract according to the call charge, and sets the line of the selected communication carrier. Thus, a technique for performing processing for connecting a caller to a subscriber has been proposed.
　例えば、特許文献４には、携帯端末が、ユーザにより設定された選択モード（料金優先、レート優先、品質優先など）に基づいて、受信した報知情報から選択すべき通信網の判定を行うことにより、ユーザの指定した条件を満たすように各エリアでの最適な通信網を選択し、通信中の移動の場合でも、予め設定された選択モードに基づいて、最適な通信網の選択及び切り替えを可能とする技術が提案されている。 For example, in Patent Document 4, a mobile terminal determines a communication network to be selected from received broadcast information based on a selection mode (charge priority, rate priority, quality priority, etc.) set by a user. Select the optimal communication network in each area to meet the conditions specified by the user, and select and switch the optimal communication network based on the preset selection mode even when moving during communication A technology has been proposed.
　例えば、特許文献５では、経路選択サービス制御装置が、着信側端末装置の現在位置と発信側端末装置の位置との距離を算出し、発信側端末種別、着信側端末種別、及び距離に応じた単位通話料金を着信側端末装置毎に抽出し、それらのうちで最低の値を示している着信側端末装置を選択し、発信側通信網に通知する技術が提案されている。 For example, in Patent Document 5, the route selection service control device calculates the distance between the current position of the receiving terminal device and the position of the calling terminal device, and responds to the calling terminal type, the receiving terminal type, and the distance. A technique has been proposed in which a unit call charge is extracted for each terminal device on the receiving side, and the terminal device on the receiving side showing the lowest value is selected and notified to the communication network on the calling side.
　例えば、特許文献６では、複数の移動通信網による通信可能な移動端末装置において、ハンドオーバーする際に、接続品質以外に、価格、容量、伝送速度、及び使用可能度に応じて最も適当なあるいは最も有利なものを選択する技術が提案されている。 For example, in Patent Document 6, in a mobile terminal apparatus capable of communication using a plurality of mobile communication networks, when performing handover, in addition to connection quality, the most appropriate or according to the price, capacity, transmission speed, and availability, or A technique for selecting the most advantageous one has been proposed.

　しかしながら、上述した特許文献１～６では、携帯電話において通信方式や通信回線を選択制御している点で共通しているが、複数の通信回線の組み合わせを考慮した通信ルートの選択とはいえず、また、発信先で発生する通信費用が通信回線選択時の判断基準に含まれていないため、発信元と発信先とが利用可能な回線の組合せで定まる通信ルート毎のトータルの通信費、通信品質、通信速度に応じて回線を選択していないため、発信元と発信先の双方にとって最適な通信回線を選択することができないという問題があった。 However, although the above-described Patent Documents 1 to 6 are common in that the communication method and the communication line are selected and controlled in the cellular phone, it cannot be said that the communication route is selected in consideration of a combination of a plurality of communication lines. In addition, since the communication cost incurred at the destination is not included in the criteria for selecting the communication line, the total communication cost and communication for each communication route determined by the combination of the lines where the source and destination can be used. Since the line is not selected according to the quality and the communication speed, there is a problem that it is not possible to select the optimum communication line for both the transmission source and the transmission destination.
　そこで本発明は、発信元、発信先の通信装置における利用可能な回線に変化があった場合でも、その都度、発信元、発信先の双方にとって最適な通信回線で通信することができる通信システム、通信回線選択方法、及びプログラムを提供することを目的とする。 Therefore, the present invention provides a communication system capable of communicating on a communication line that is optimal for both the transmission source and the transmission destination, even when there is a change in the available line in the communication device of the transmission source and the transmission destination. It is an object to provide a communication line selection method and program.

The communication device that wants to acquire information sends an output request for the currently available line to the other communication device in a predetermined format using mail, SMS (short message), various commands, etc. When receiving the request, the communication device outputs the used line information to the request source in a predetermined format.
　第２の方法では、情報を取得しようとする通信装置は、現在接続中の回線を用いて、通信回線網にアクセスし、通信回線網上の通信キャリア等の回線提供社のデータベースにアクセスして、提供されているサービス（ＬＴＥ、ＷＣＤＭＡ、ＧＳＭ（登録商標）、無線ＬＡＮなど）、及びそのサービス範囲と自身の位置情報、及び自身が対応しているサービスを比較して、利用可能なサービスを判定する。 In the second method, a communication device to acquire information accesses a communication line network using a currently connected line, and accesses a database of a line provider such as a communication carrier on the communication line network. Compare available services (LTE, WCDMA, GSM (registered trademark), wireless LAN, etc.), their service range with their location information, and the services they support judge.
　第３の方法では、現在接続している回線の通信回線サーバから、適宜、利用可能な回線の情報を通信装置に報知するようにすることで、通信装置は、通信回線サーバから報知される情報を参照する。 In the third method, the communication apparatus notifies the communication apparatus of information on available lines as appropriate from the communication line server of the currently connected line, so that the communication apparatus can receive information notified from the communication line server.

(Route) is searched and communication route information 105 is created. Based on the available line information between the communication device 10a and the communication device 10b, the communication route detailed information generation unit 113 determines the communication cost, communication quality, and communication in each route from the communication cost, communication quality, and communication speed in each line. Detailed communication route information 106 associated with the speed is generated.
　通信ルート比較部１１４は、通信装置１０ａと通信装置１０ｂとの間におけるルート毎の通信費、通信品質、通信速度を比較する。通信ルート選択部１１５は、上記比較結果に基づいて、予め設定されている選択条件（最も安価なルート、最も通信品質の高いルート、最も通信速度が速いルートなど）に従って、例えば、最も安価なルート、あるいは最も通信品質の高いルート、あるいは最も通信速度が速いルートなど、最適な通信ルートを選択する。 The communication route comparison unit 114 compares the communication cost, communication quality, and communication speed for each route between the communication device 10a and the communication device 10b. Based on the comparison result, the communication route selection unit 115 performs, for example, the cheapest route according to the preset selection conditions (the cheapest route, the route with the highest communication quality, the route with the fastest communication speed, etc.). Alternatively, an optimal communication route such as a route having the highest communication quality or a route having the highest communication speed is selected.
　通信回線切替要求出力部１１６は、選択した最適な通信ルートを構成する回線が現在の回線と異なる場合に、最適な通信ルートを構成する回線となるように、通信回線サーバや発信先の通信装置１０ｂに回線の切替を要求する。通信回線切替部１１７は、選択した最適な通信ルートを構成する回線が現在の回線と異なる場合に、最適な通信ルートを構成する回線となるように回線を切り替える。通信回線確立部１１８は、切り替えた回線で発信先の通信端末１０ｂとの通信を確立する。なお、図２において、通信回線切替要求出力部１１６、通信回線切替部１１７、及び通信回線確立部１１８は、通信制御部１００に設けるようにしてもよい。 The communication line switching request output unit 116, when the line constituting the selected optimum communication route is different from the current line, the communication line server and the destination communication device so as to become the line constituting the optimum communication route. Request line switching to 10b. The communication line switching unit 117 switches the line so as to be the line constituting the optimum communication route when the line constituting the selected optimum communication route is different from the current line. The communication line establishment unit 118 establishes communication with the communication terminal 10b as the transmission destination via the switched line. In FIG. 2, the communication line switching request output unit 116, the communication line switching unit 117, and the communication line establishment unit 118 may be provided in the communication control unit 100.
　図３は、本第１実施形態による通信ルート情報１０５の一例を示す概念図である。図１に示すように、発信元の通信装置１０ａが利用可能な回線Ａ、Ｂ、Ｃがあり、発信先の通信装置１０ｂが利用可能な回線ａ、ｂ、ｃがある場合、利用可能な回線の全ての組み合わせ（ルート）は、ルートＲ１（Ａ－ａ）、Ｒ２（Ａ－ｂ）、Ｒ３（Ａ－ｃ）、Ｒ４（Ｂ－ａ）、Ｒ５（Ｂ－ｂ）、Ｒ６（Ｂ－ｃ）、Ｒ７（Ｃ－ａ）、Ｒ８（Ｃ－ｂ）、Ｒ９（Ｃ－ｃ）となる。通信ルート情報１０５には、これら利用可能な回線の全ての組み合わせルートＲ１～Ｒ９が保持されている。 FIG. 3 is a conceptual diagram showing an example of the communication route information 105 according to the first embodiment.

The communication route information 105 holds all the combined routes R1 to R9 of these available lines.
　図４は、本第１実施形態による通信ルート詳細情報１０６の一例を示す概念図である。通信ルート詳細情報１０６は、各ルートＲ１～Ｒ９を利用した場合にかかる単位時間当たりの通信費、通信品質（Ｂａｄ＜Ｍｉｄｉｕｍ＜Ｇｏｏｄ）、通信速度が保持されている。該通信ルート詳細情報１０６の内容に基づいて、どのルートが最適であるかが判定され、最適なルートが選択（自動、手動）されることになる。なお、通信費は、使用する回線によっては、発信元と発信先とで異なる場合がある。そこで、本第１実施形態では、発信元でかかる通信費と発信先でかかる通信費との合計としている。 FIG. 4 is a conceptual diagram showing an example of the communication route detailed information 106 according to the first embodiment. The communication route detailed information 106 holds the communication cost per unit time, the communication quality (Bad <Midium <Good), and the communication speed when each of the routes R1 to R9 is used. Based on the contents of the communication route detailed information 106, it is determined which route is optimum, and the optimum route is selected (automatic or manual). Note that the communication cost may differ between the transmission source and the transmission destination depending on the line used. Therefore, in the first embodiment, the total of the communication cost for the transmission source and the communication cost for the transmission destination is used.
　図５は、本第１実施形態による通信装置１０ａの動作を説明するためのフローチャートである。通信装置１０ａにおいて、ユーザにより発信（発呼）操作があると、まず、利用可能回線情報取得部１１１ｇ、上述した方法により、発信元の通信装置１０ａの利用可能回線情報と、発信先の通信装置１０ｂの利用可能回線情報を取得する（ステップＳ１０）。次に、通信ルート探索部１１２は、利用可能回線情報取得部１１１により取得された、通信装置１０ａと通信装置１０ｂとの利用可能回線情報を参照し、利用可能な回線の全ての組み合わせであるルートＲ１～Ｒ９を探索し、通信ルート情報１０５としてＲＡＭ１０４に保存する（ステップＳ１２；図３参照）。次に、通信ルート詳細情報生成部１１３は、通信装置１０ａと通信装置１０ｂとの利用可能な回線情報に基づき、各回線における通信費、通信品質、及び通信速度から、各ルートにおける通信費、通信品質、通信速度を紐付た通信ルート詳細情報１０６を生成し、ＲＡＭ１０４に保存する（ステップＳ１４；図４）。 FIG. 5 is a flowchart for explaining the operation of the communication device 10a according to the first embodiment.

Next, based on the comparison result, the communication route selection unit 115, for example, according to the preset selection conditions (the cheapest route, the route with the highest communication quality, the route with the highest communication speed, etc.) An optimal communication route such as an inexpensive route, a route with the highest communication quality, or a route with the highest communication speed is selected (step S18).
　なお、通信ルートの選択は、通信装置１０ａが予め設定されている選択条件（最も安価なルート、最も通信品質の高いルート、最も通信速度が速いルートなど）に従って自動的に選択するのではなく、上記通信ルート比較部１１４による比較結果を表示部１０１に表示し、ユーザにより選択させるようにしてもよい。このとき、ユーザは、所望する条件で、例えば、通信費が安価なルート順、あるいは通信品質が高いルート順、あるいは通信速度が速いルート順に並べ替えて選択するようにしてもよい。 Note that the communication route is not automatically selected according to the selection conditions (the cheapest route, the route with the highest communication quality, the route with the fastest communication speed, etc.) preset by the communication device 10a. The comparison result by the communication route comparison unit 114 may be displayed on the display unit 101 and selected by the user. At this time, the user may rearrange and select, for example, in order of a route with a low communication cost, a route with a high communication quality, or a route with a high communication speed under desired conditions.

When the line switching is necessary (YES in step S40). Then, a switching request is sent to the source communication device 10a and the destination communication device 10b so as to switch the current line to the line of the selected communication route (step S42).

　図１３は、本第４実施形態による通信装置１０ａ、通信回線サーバ３０Ａの動作を説明するためのフローチャートである。ユーザにより発信（発呼）操作があると、通信装置１０ａでは、利用可能回線情報の取得要求を、通信回線サーバ３０Ａに送信する（ステップＳ７０）。これに対して、通信回線サーバ３０Ａでは、利用可能回線情報取得部２０７が、上述した方法により、発信元の通信装置１０ａの利用可能回線情報と、発信先の通信装置１０ｂの利用可能回線情報を取得し、通信装置１０ａに送信する（ステップＳ９０）。 FIG. 13 is a flowchart for explaining the operation of the communication device 10a and the communication line server 30A according to the fourth embodiment. When the user performs a calling (calling) operation, the communication device 10a transmits an acquisition request for available line information to the communication line server 30A (step S70). On the other hand, in the communication line server 30A, the available line information acquisition unit 207 obtains the available line information of the source communication device 10a and the available line information of the destination communication device 10b by the method described above. It is acquired and transmitted to the communication device 10a (step S90).
　通信装置１０ａでは、通信回線サーバ３０Ａから利用可能回線情報を受け取ると、
通信ルート探索部１１２が、通信装置１０ａと通信装置１０ｂとの利用可能回線情報を参照し、利用可能な回線の全ての組み合わせであるルートＲ１～Ｒ９を探索し、通信ルート情報１０５としてＲＡＭ１０４に保存する（ステップＳ７２）。次に、通信ルート詳細情報生成部１１３は、通信装置１０ａと通信装置１０ｂとの利用可能な回線情報に基づき、各回線における通信費、通信品質、及び通信速度から、各ルートにおける通信費、通信品質、通信速度を紐付た通信ルート詳細情報１０６を生成し、ＲＡＭ１０４に保存するとともに、通信回線サーバ３０Ａに送信する（ステップＳ７４）。 When the communication device 10a receives the available line information from the communication line server 30A,
The communication route search unit 112 refers to the available line information between the communication device 10 a and the communication device 10 b, searches for the routes R 1 to R 9 that are all combinations of available lines, and stores them in the RAM 104 as the communication route information 105. (Step S72). Next, the communication route detailed information generating unit 113, based on the available line information between the communication device 10a and the communication device 10b, determines the communication cost and communication in each route from the communication cost, communication quality, and communication speed in each line. Detailed communication route information 106 associated with quality and communication speed is generated, stored in the RAM 104, and transmitted to the communication line server 30A (step S74).
　通信回線サーバ３０Ａでは、通信ルート比較部２１０が、通信装置１０ａと通信装置１０ｂとの間におけるルートＲ１～Ｒ９の通信費、通信品質、通信速度を比較する（ステップＳ９２）。次に、通信ルート選択部２１１は、上記比較結果に基づいて、予め設定されている選択条件（最も安価なルート、最も通信品質の高いルート、最も通信速度が速いルートなど）に従って、例えば、最も安価なルート、あるいは最も通信品質の高いルート、あるいは最も通信速度が速いルートなど、最適な通信ルートを選択し、通信装置１０ａに送信する（ステップＳ９４）。 In the communication line server 30A, the communication route comparison unit 210 compares the communication costs, communication quality, and communication speed of the routes R1 to R9 between the communication device 10a and the communication device 10b (step S92). Next, based on the comparison result, the communication route selection unit 211, for example, according to the preset selection conditions (the cheapest route, the route with the highest communication quality, the route with the fastest communication speed, etc.) An optimum communication route such as an inexpensive route, a route with the highest communication quality, or a route with the highest communication speed is selected and transmitted to the communication device 10a (step S94).
　通信装置１０ａでは、通信回線切替部１１７が、自身の回線を切り替える必要があるか判定し（ステップＳ７６）、回線切替が必要である場合には（ステップＳ７６のＹＥＳ）、通信回線サーバ３０Ａに対して、現在の回線を選択された通信ルートの回線に切り替えるように切替要求を送出し（ステップＳ７８）、現在の回線を、選択された通信ルートの回線に切り替える（ステップＳ２４）。このとき、必要に応じて切替が完了したことを相手装置に通知するようにしてもよい。 In the communication device 10a, the communication line switching unit 117 determines whether it is necessary to switch its own line (step S76), and when line switching is required (YES in step S76), the communication line server 30A Then, a switching request is sent to switch the current line to the line of the selected communication route (step S78), and the current line is switched to the line of the selected communication route (step S24). At this time, you may make it notify a partner apparatus that switching was completed as needed.
　通信回線サーバ３０Ａでは、回線の切替要求を受信すると、発信先の通信装置１０ｂに対して、現在の回線を選択された通信ルートの回線に切り替えるように切替要求を送出する（ステップＳ９６）。その後、次の処理へ進む。 When the communication line server 30A receives the line switching request, the communication line server 30A sends a switching request to the destination communication device 10b so as to switch the current line to the line of the selected communication route (step S96). Thereafter, the process proceeds to the next process.
　また、通信装置１０ａでは、回線切替が完了すると、通信回線確立部１１８は、選択された通信ルート（回線）を用いて、通信先の通信装置１０ｂと通信を確立して通信を開始する（ステップＳ８２）。一方、回線切替が必要でない場合には（ステップＳ７６のＮＯ）、回線切替することなく、選択された通信ルート（回線）を用いて、通信先の通信装置１０ｂと通信を確立して通信を開始する（ステップＳ８２）。 In the communication device 10a, when the line switching is completed, the communication line establishment unit 118 establishes communication with the communication device 10b as the communication destination using the selected communication route (line) and starts communication (step). S82). On the other hand, when line switching is not necessary (NO in step S76), communication is established with the communication apparatus 10b as the communication destination using the selected communication route (line) without switching the line and communication is started. (Step S82).
　上述した第４実施形態によれば、発信元の通信装置１０ａ、または／及び発信先の通信装置１０ｂにおける利用可能な回線に変化があった場合でも、その都度、双方にとって最適な通信回線で通信することができる。 According to the above-described fourth embodiment, even when there is a change in the available line in the transmission source communication device 10a and / or the transmission destination communication device 10b, communication is performed on the communication line that is optimal for both. can do.
　また、上述した第４実施形態によれば、発信元の通信装置１０ａとしては、端末情報、位置情報等の必要情報だけを通知すれば、現在利用可能な回線の情報を入手できるため、端末ユーザにとっての利便性を高くすることができる。 Further, according to the above-described fourth embodiment, since only the necessary information such as terminal information and location information can be notified as the source communication device 10a, information on the currently available line can be obtained. The convenience for the user can be increased.
　また、上述した第４実施形態によれば、発信元の通信装置１０ａが、複数の回線の組み合わせからなる通信ルートを探索する機能や通信ルートの比較機能を持つことで、既存のシステム（ネットワーク）に変更を加えることなしに、通信相手側の回線を含めた最適な通信路を確認することができる。 Further, according to the above-described fourth embodiment, the source communication device 10a has a function of searching for a communication route composed of a combination of a plurality of lines and a function of comparing communication routes, so that an existing system (network) It is possible to confirm the optimum communication path including the communication partner side line without making any changes to.
　なお、上述した第１乃至第４実施形態では、利用可能回線情報を取得する際の１つの方法として、メール、ＳＭＳ(ショートメッセージ)、各種コマンメール、ＳＭＳ(ショートメッセージ)、各種コマンド等を用い所定のフォーマットで送受信する方法を説明したが、この手法は、利用可能回線情報の取得だけに限らず、通信回線の設定（切替を含む）が完了した旨を通知する際に用いていもよい。通信装置１０ａ、１０ｂは、該通信回線の設定（切替を含む）が完了した旨の通知を受け取ると、通信相手へ電話をかければよい（通常の電話番号発信処理をすればよい）。 In the first to fourth embodiments described above, mail, SMS (short message), various command emails, SMS (short message), various commands, etc. are used as one method for acquiring usable line information. Although the method of transmitting and receiving in a predetermined format has been described, this method is not limited to the acquisition of usable line information, but may be used when notifying that the setting (including switching) of the communication line has been completed. When the communication devices 10a and 10b receive notification that the setting (including switching) of the communication line is completed, the communication devices 10a and 10b may make a call to the communication partner (a normal telephone number transmission process may be performed).
