Description

本発明は、通信距離がほぼ等しく、待機時消費電力の大きさが異なる２つの近接無線通信手段を備えた通信装置、及び、コンピュータを通信装置として機能させるプログラムに関するものである。   The present invention relates to a communication apparatus including two close proximity wireless communication units having substantially the same communication distance and different standby power consumption, and a program for causing a computer to function as a communication apparatus.

近年、決済や認証を行うため、近接無線通信手段であるＩＳＯ１４４４３方式に準拠した通信手段(以下、低速近接無線通信手段)を搭載した機器が普及してきている。ＩＳＯ１４４４３方式に代表される低速近接無線通信手段は、通信レートが低く、一方で通信待機時の消費電力が非常に小さい特徴を持つ。よって、ユーザがいつでも低速近接無線通信手段を使用したサービスを利用できることを目的とし、無線通信部に対し常時電力を供給して待機させる待ち受け方法が一般的に採用されている。   In recent years, in order to perform settlement and authentication, devices equipped with communication means (hereinafter referred to as low-speed proximity wireless communication means) compliant with the ISO 14443 method, which is a proximity wireless communication means, have become widespread. The low-speed proximity wireless communication means represented by the ISO 14443 system has a feature that the communication rate is low, while the power consumption during communication standby is very small. Therefore, a standby method is generally employed in which a user always uses the low-speed proximity wireless communication means to use a service and always waits by supplying power to the wireless communication unit.

また、音楽や写真データなど様々なデータを高速にやり取りするため、ＩＥＥＥ８０２．１５．１規格に代表される近接無線通信手段(以下、高速近接無線通信手段)に対応した機器も普及してきている。高速近接無線通信手段は、上述の低速近接無線通信手段に比べて、通信待機時の消費電力が大きな反面、大容量のデータを高速にやり取りできる特徴がある。最近では、従来の無線技術の課題であった複雑な接続設定を不要にし、データ転送したいファイルを選択して２台の機器を所定の距離内に接近させるだけで大容量のデータを高速にやり取りできる高速近接無線通信手段も開発されている(例えば、非特許文献１参照)。携帯電話では、様々なサービスアプリケーションに対応するため、上記低速近接無線通信手段と高速近接無線通信手段の２つを備えたものも製品化されている。   In addition, in order to exchange various data such as music and photo data at high speed, devices compatible with close proximity wireless communication means (hereinafter referred to as high speed close proximity wireless communication means) typified by the IEEE 802.15.1 standard have become widespread. The high-speed proximity wireless communication means has a feature that it can exchange high-capacity data at a high speed, while it consumes more power during communication standby than the low-speed proximity wireless communication means described above. Recently, complicated connection setup, which was a problem with conventional wireless technology, is no longer required, and a large amount of data can be exchanged at high speed simply by selecting a file to be transferred and bringing two devices within a specified distance. High-speed proximity wireless communication means that can be used have also been developed (see, for example, Non-Patent Document 1). In order to cope with various service applications, mobile phones including two low-speed proximity wireless communication means and high-speed proximity wireless communication means have been commercialized.

しかしながら、携帯電話のようなバッテリ駆動のモバイル機器に対して、待機時消費電力の大きいＩＥＥＥ８０２．１５．１規格等の高速近接無線通信が搭載される場合、ＩＳＯ１４４４３方式と同じように無線通信部に対して常時電力を供給して起動させておくとバッテリを激しく消耗してしまい、モバイル機器を使用できる時間が短くなってしまう問題がある。   However, when battery-powered mobile devices such as mobile phones are equipped with high-speed proximity wireless communication such as the IEEE 802.15.1 standard, which consumes a large amount of power during standby, the wireless communication unit is connected to the wireless communication unit in the same way as the ISO 14443 method. On the other hand, if power is constantly supplied and started up, the battery is consumed violently, and there is a problem that the time for which the mobile device can be used is shortened.

そこで、特許文献１には、データ通信を実施していない場合は無線通信部への電力供給を行わずに待機させることで無線通信部の電力消費を無くし、上記無線通信部を使用したアプリケーション起動に連動させて無線通信部への電力供給を開始することで、データ通信を実施している時にのみ上記無線通信部へ電力供給し、省電力化を図る方法が開示されている。   Therefore, in Patent Document 1, when data communication is not performed, the power consumption of the wireless communication unit is eliminated by waiting without supplying power to the wireless communication unit, and application activation using the wireless communication unit is performed. A method is disclosed in which power is supplied to the wireless communication unit only when data communication is performed by starting power supply to the wireless communication unit in conjunction with the wireless communication unit to save power.

例えば、携帯電話で普及している赤外線通信によるファイル交換アプリケーションでは上記の技術を使用しており、２台の携帯電話間でファイル交換を行う前に、ファイル送信を行う機器側ではファイル送信用途のアプリケーションを立ち上げ、ファイル受信を行う機器側ではファイル受信用途のアプリケーションを立ち上げるユーザ操作が必要であった。   For example, a file exchange application using infrared communication that is widely used in mobile phones uses the above-described technology. Before exchanging a file between two mobile phones, the device that transmits the file uses a file transmission application. On the device side that starts an application and receives a file, a user operation for starting an application for receiving a file is required.

しかし、高速近接無線通信部の待機方法として特許文献１に記載の技術を用いた場合、ユーザは、高速近接無線通信を使用したデータ通信を実行する前に、送信側／受信側どちらの端末においてもアプリケーションを起動しなければならないことから、片方の機器のみ操作してデータを送受信するといった簡単な使用方法ができず、ユーザの使い勝手が悪いという問題があった。   However, when the technique described in Patent Document 1 is used as a standby method of the high-speed proximity wireless communication unit, the user can execute data communication using the high-speed proximity wireless communication at either the transmission side or the reception side terminal. However, since the application has to be started, there is a problem that it is not easy to use, such as operating only one device to send and receive data, and user convenience is poor.

本発明は、上記問題に鑑みてなされたものであり、通信待機時の消費電力が大きな近接無線通信手段の省電力化を図りつつ、煩雑な操作無しで近接無線通信を使用したデータの送受信が実行可能なユーザ利便性の高い通信装置等を提供することを目的とする。   The present invention has been made in view of the above problems, and can transmit and receive data using proximity wireless communication without complicated operations while saving power of the proximity wireless communication means that consumes a large amount of power during communication standby. An object of the present invention is to provide a communication device and the like that can be executed with high user convenience.

A device for minimizing standby power consumption of the two close proximity wireless communication means in the communication device including the close proximity wireless communication means capable of transmitting and receiving will be described.
In this embodiment, the proximity wireless communication means (hereinafter referred to as the first proximity wireless communication means) with low power consumption such as ISO 14443 method is always supplied with power to stand by, and the proximity power consumption such as IEEE 802.15.1 is large. The standby power consumption of the two close proximity wireless communication means is minimized by performing standby without supplying power to the wireless communication means (hereinafter referred to as second close proximity wireless communication means), and such An activation method of the second proximity wireless communication unit when two devices that employ the communication standby method perform data transmission / reception using the second proximity wireless communication unit will be described.

まず、図１に本発明の実施形態１に係るデータを送信する側の通信装置１の構成を示し、図２に本発明の実施形態１に係るデータを受信する側の通信装置２の構成を示す。   First, FIG. 1 shows the configuration of the communication device 1 on the data transmission side according to Embodiment 1 of the present invention, and FIG. 2 shows the configuration of the communication device 2 on the data reception side according to Embodiment 1 of the present invention.

アンテナ１１１ａ及びアンテナ１１２ａは、近接無線通信システムの無線信号を、通信装置１が送受信するための装置である。   The antenna 111a and the antenna 112a are devices for the communication device 1 to transmit and receive a radio signal of the close proximity wireless communication system.

通信部１１は、複数の近接無線通信に利用する変復調回路や通信プロトコルを実装し、第１近接無線通信部１１１及び第２近接無線通信部１１２を備える。第１近接無線通信部１１１は、アンテナ１１１ａを介して送受信した信号に関する処理を行う変復調回路や通信プロトコルを実装する。第２近接無線通信部１１２は、アンテナ１１２ａを介して送受信した信号に関する処理を行う変復調回路や通信プロトコルを実装する。   The communication unit 11 includes a first proximity wireless communication unit 111 and a second proximity wireless communication unit 112, which are equipped with a modulation / demodulation circuit and a communication protocol used for a plurality of proximity wireless communication. The first proximity wireless communication unit 111 implements a modulation / demodulation circuit and a communication protocol that perform processing related to signals transmitted and received via the antenna 111a. The second proximity wireless communication unit 112 implements a modulation / demodulation circuit and a communication protocol that perform processing related to signals transmitted and received via the antenna 112a.

第１近接無線通信部１１１は、通信レートは低いが、待機時消費電力が非常に小さい特徴を持つ無線通信方式に対応したものであり、例えばＩＳＯ１４４４３方式に準拠した近接無線通信やＲＦＩＤ（Radio Frequency IDentification）等に相当する。   The first proximity wireless communication unit 111 is compatible with a wireless communication method having a low communication rate but a very low standby power consumption. For example, the first proximity wireless communication unit 111 is compatible with a wireless communication method or RFID (Radio Frequency) based on the ISO 14443 method, for example. IDentification).

また、携帯電話などデータの送受信どちらの機能も持つような通信装置に関しては、省電力制御部１３２と省電力制御部２３２の両方の処理部を併せ持つようにしても良い。   For a communication apparatus having both functions of transmitting and receiving data such as a cellular phone, both the power saving control unit 132 and the power saving control unit 232 may be included.

続いて、図３の処理シーケンスを参照して、本発明の実施形態１における通信装置１と通信装置２の２台の通信装置が、近接無線通信を使用してデータ送受信を開始する前の、それぞれの通信装置における内部処理、及びデータ通信開始までの処理について説明する。   Subsequently, with reference to the processing sequence of FIG. 3, before the two communication devices of the communication device 1 and the communication device 2 according to the first embodiment of the present invention start data transmission / reception using close proximity wireless communication, The internal processing in each communication device and processing up to the start of data communication will be described.

図３の処理シーケンスは、ユーザが通信装置１に対して通信装置２へのデータ送信要求を指示してから、両装置が第２近接無線通信を使用したデータ通信を開始するまでの通信装置１の省電力制御部１３２、及び通信装置２の省電力制御部２３２の動作について説明したものである。   In the processing sequence of FIG. 3, the communication device 1 from when the user instructs the communication device 1 to send a data transmission request to the communication device 2 until both devices start data communication using the second proximity wireless communication. The operations of the power saving control unit 132 and the power saving control unit 232 of the communication device 2 are described.

本処理シーケンスは、データ送信側の通信装置１に対して電源が投入されることによって開始される。なお、データ受信側の通信装置２に関しては通信装置１に対して少なくとも電源が投入されたときには既に電源が投入されていることが前提とする。更に通信装置１及び通信装置２の起動後、通信装置１の第２近接無線通信部１１２及び通信装置２の第２近接無線通信部２１２に対しては電源を供給せずに待機させる。   This processing sequence is started when the communication apparatus 1 on the data transmission side is turned on. It is assumed that the communication device 2 on the data receiving side is already turned on at least when the communication device 1 is turned on. Furthermore, after the communication device 1 and the communication device 2 are activated, the second close proximity wireless communication unit 112 of the communication device 1 and the second close proximity wireless communication unit 212 of the communication device 2 are made to stand by without supplying power.

なお、上記以外にも、通信実行時よりも低いクロックを供給して動作させるスリープ動作や、クロックの供給を停止するディープスリープ動作、のいずれかの動作状態で待機させるようにしても良い。このような動作状態にすることで第２近接無線通信部１１２及び第２近接無線通信部２１２の省電力化を図ることが可能となり、電源供給を停止する方法とほぼ同様の効果を得ることが可能である。   In addition to the above, it is also possible to wait in one of the operation states of a sleep operation in which a clock lower than that at the time of communication execution is operated and a deep sleep operation in which the clock supply is stopped. By making such an operating state, it is possible to save power in the second proximity wireless communication unit 112 and the second proximity wireless communication unit 212, and it is possible to obtain substantially the same effect as the method of stopping power supply. Is possible.

まず、データ送信側の通信装置１の第２近接通信開始要求監視部１３２１は、自通信装置１が備える第２近接通信アプリ１４１を起動後、データ送信開始時に発行される第２近接無線通信部１１１を使用した通信の開始要求があるかどうかを判定する（ステップＳ３００）。   First, the second close proximity communication start request monitoring unit 1321 of the communication device 1 on the data transmission side starts the second close proximity communication application 141 included in the self communication device 1 and then is issued when starting data transmission. It is determined whether there is a request to start communication using 111 (step S300).

ステップＳ３００において、第２近接無線通信部１１１を使用した通信の開始要求がないと判定された場合(ステップＳ３００；Ｎｏ)は、ステップＳ３００に遷移する。第２近接通信開始要求監視部１３２１は、第２近接無線通信部１１１を使用した通信の開始要求があるかどうかの判定を再び行う（ステップＳ３００）。   In Step S300, when it is determined that there is no request for starting communication using the second proximity wireless communication unit 111 (Step S300; No), the process proceeds to Step S300. The second proximity communication start request monitoring unit 1321 determines again whether there is a request to start communication using the second proximity wireless communication unit 111 (step S300).

一方、ステップＳ３００において、第２近接無線通信部１１１を使用した通信の開始要求があると判定された場合(ステップＳ３００；Ｙｅｓ)は、ステップＳ３０１に遷移する。ターゲット第２近接通信起動要求送信部１３２２は、対向する通信装置２が備える第２近接無線通信部２１２の起動要求を、第１近接無線通信部１１１を介して送信する（ステップＳ３０１）。ここで、ターゲット第２近接通信起動要求送信部１３２２は、第２近接無線通信部２１２の起動要求を所定の間隔毎に複数回送信しても良い。そのようにすることで、対向する通信装置２において本起動要求を取りこぼしたとしても、そのことに起因する通信接続のエラーを回避することが可能となる。   On the other hand, when it is determined in step S300 that there is a request to start communication using the second close proximity wireless transfer unit 111 (step S300; Yes), the process proceeds to step S301. The target second proximity communication activation request transmission unit 1322 transmits an activation request for the second proximity wireless communication unit 212 included in the opposing communication device 2 via the first proximity wireless communication unit 111 (step S301). Here, the target second proximity communication activation request transmission unit 1322 may transmit the activation request of the second proximity wireless communication unit 212 a plurality of times at predetermined intervals. By doing so, even if the main activation request is missed in the opposing communication device 2, it is possible to avoid a communication connection error caused by that.

一方、データ受信側の通信装置２では、第２近接通信起動要求監視部２３２１が、対向する通信装置１から送信された第２近接無線通信部２１２の起動要求を、第１近接無線通信部２１１を介して受信したかどうかを判定する（ステップＳ３０２）。   On the other hand, in the communication device 2 on the data reception side, the second proximity communication activation request monitoring unit 2321 sends the activation request for the second proximity wireless communication unit 212 transmitted from the opposite communication device 1 to the first proximity wireless communication unit 211. It is determined whether it is received via (step S302).

ステップＳ３０２において、第２近接無線通信部２１２の起動要求を受信していないと判定された場合(ステップＳ３０２；Ｎｏ)、ステップＳ３０２に遷移する。第２近接通信起動要求監視部２３２１は、第１近接無線通信部２１１を介して、第２近接無線通信部２１２の起動要求を受信したかどうかの判定を再び行う（ステップＳ３０２）。   If it is determined in step S302 that the activation request for the second close proximity wireless communication unit 212 has not been received (step S302; No), the process proceeds to step S302. The second proximity communication activation request monitoring unit 2321 determines again whether or not the activation request for the second proximity wireless communication unit 212 has been received via the first proximity wireless communication unit 211 (step S302).

一方、ステップＳ３０２において、第２近接無線通信部２１２の起動要求を受信したと判定された場合(ステップＳ３０２；Ｙｅｓ)、ステップＳ３０３に遷移する。第２近接通信起動制御部２３２２は、電源コントローラ１２１を介して第２近接無線通信部２１２に電源供給を開始して、第２近接無線通信部２１２に対して起動要求を行う（ステップＳ３０３）。   On the other hand, when it determines with having received the starting request | requirement of the 2nd close proximity wireless transfer part 212 in step S302 (step S302; Yes), it changes to step S303. The second proximity communication activation control unit 2322 starts power supply to the second proximity wireless communication unit 212 via the power controller 121 and makes an activation request to the second proximity wireless communication unit 212 (step S303).

そして、第２近接無線通信部２１２は、第２近接通信起動制御部２３２２からの起動要求を受けて起動する（ステップＳ３０４）。ステップＳ３０４において、通信装置２の第２近接無線通信部２１２が起動した後、第２近接通信起動要求応答送信部２３２３は、第２近接無線通信部２１２の起動要求に対する応答を、第１近接無線通信部２１１を介して通信装置１に送信する（ステップＳ３０５）。ここで、第２近接通信起動要求応答送信部２３２３は、第２近接無線通信部２１２の起動要求に対する応答を、所定の間隔毎に複数回送信しても良い。そのようにすることで、対向する通信装置１で本起動要求に対する応答を取りこぼしたとしても、そのことに起因するエラーを回避することが可能となる。   Then, the second proximity wireless communication unit 212 is activated in response to the activation request from the second proximity communication activation control unit 2322 (step S304). In step S304, after the second proximity wireless communication unit 212 of the communication device 2 is activated, the second proximity communication activation request response transmission unit 2323 transmits a response to the activation request of the second proximity wireless communication unit 212 as the first proximity wireless communication unit 212. It transmits to the communication apparatus 1 via the communication part 211 (step S305). Here, the second proximity communication activation request response transmission unit 2323 may transmit a response to the activation request of the second proximity wireless communication unit 212 a plurality of times at predetermined intervals. By doing so, even if the response to the activation request is missed by the opposing communication device 1, it is possible to avoid an error caused by that.

通信装置１では、ステップＳ３０１の後、ターゲット第２近接通信起動判定部１３２３は、第２近接無線通信部２１２の起動要求に対する応答を、第１近接無線通信部１１１を介して受信したかどうかの判定を行う（ステップＳ３０６）。   In communication device 1, after step S <b> 301, target second proximity communication activation determination unit 1323 determines whether a response to the activation request of second proximity wireless communication unit 212 has been received via first proximity wireless communication unit 111. A determination is made (step S306).

ステップＳ３０６において、第２近接無線通信部２１２の起動要求に対する応答を対向する通信装置２から受信していないと判定された場合(ステップＳ３０６；Ｎｏ)、ステップＳ３０６に遷移する。ターゲット第２近接通信起動判定部１３２３は、第２近接無線通信部２１２の起動要求に対する応答を対向する通信装置２から受信したかどうかの判定を再び行う（ステップＳ３０６）。   If it is determined in step S306 that a response to the activation request of the second close proximity wireless transfer unit 212 has not been received from the opposing communication device 2 (step S306; No), the process proceeds to step S306. The target second proximity communication activation determining unit 1323 determines again whether or not a response to the activation request of the second proximity wireless communication unit 212 has been received from the facing communication device 2 (step S306).

一方、ステップＳ３０６において、第２近接無線通信部２１２の起動要求に対する応答を対向する通信装置２から受信したと判定された場合(ステップＳ３０６；Ｙｅｓ)、ステップＳ３０７に遷移する。第２近接通信部起動制御部１３２４は、電源コントローラ１２１を介して第２近接無線通信部１１１に対して電源供給を開始して、第２近接無線通信部１１２に対して起動要求を行う（ステップＳ３０７）。   On the other hand, when it determines with having received the response with respect to the starting request | requirement of the 2nd near field communication part 212 from the communication device 2 which opposes in step S306 (step S306; Yes), it changes to step S307. The second proximity communication unit activation control unit 1324 starts power supply to the second proximity wireless communication unit 111 via the power controller 121 and makes an activation request to the second proximity wireless communication unit 112 (step). S307).

そして、第２近接無線通信部１１２は、第２近接通信部起動制御部１３２４からの起動要求を受けて起動する（ステップＳ３０８）。ステップＳ３０８において、通信装置１の第２近接無線通信部１１１が起動した後、第２近接通信確立要求送信部１３２５は、第２近接無線通信における通信路の確立要求を、第２近接無線通信部１１２を介して通信装置２に対し送信する（ステップＳ３０９）。   Then, the second proximity wireless communication unit 112 is activated in response to an activation request from the second proximity communication unit activation control unit 1324 (step S308). In step S308, after the second proximity wireless communication unit 111 of the communication device 1 is activated, the second proximity communication establishment request transmission unit 1325 sends a communication path establishment request in the second proximity wireless communication to the second proximity wireless communication unit. It transmits to the communication apparatus 2 via 112 (step S309).

なお、通信装置１では、ステップＳ３０１の実行後、ステップＳ３０６の判定を実行せずにステップＳ３０７に遷移して、第２近接無線通信部１１１の電源供給を開始するようにしても良い。その際、通信装置２では、ステップＳ３０４の後、ステップＳ３０５における第２近接無線通信部２１２の起動要求に対する応答を送信しないこととなる。   Note that, after the execution of step S301, the communication device 1 may transition to step S307 without executing the determination of step S306 and start the power supply of the second proximity wireless communication unit 111. At that time, in step S304, the communication device 2 does not transmit a response to the activation request for the second close proximity wireless transfer unit 212 in step S305.

そのようにすることで、通信装置２の第２近接無線通信部２１２が正常に起動できたかどうかの判定を、通信装置１ができないというデメリットがあるが、第２近接無線通信の開始までの時間を短縮できる効果がある。なお、上記デメリットに関しては、第２近接無線通信の通信確立が一定時間できなければ、通信装置２の第２近接無線通信部２１２が正常に起動していないと判定することで、同等の効果を得られるため解消することが可能である。   By doing so, there is a demerit that the communication device 1 cannot determine whether or not the second proximity wireless communication unit 212 of the communication device 2 has been normally activated, but the time until the start of the second proximity wireless communication There is an effect that can be shortened. In addition, regarding the above disadvantages, if the second close proximity wireless communication cannot be established for a certain period of time, it is determined that the second close proximity wireless communication unit 212 of the communication device 2 is not normally activated, thereby obtaining an equivalent effect. Since it is obtained, it can be solved.

なお、ステップＳ３０４とステップＳ３０８において、通信装置１及び通信装置２の起動後、それぞれの第２近接無線通信部１１２と第２近接無線通信部２１２とが、スリープ動作またはディープスリープ動作で待機している場合は、電源供給ではなく、通信実行時に使用すべき通常のクロックを供給することとする。   In step S304 and step S308, after the communication device 1 and the communication device 2 are activated, the second proximity wireless communication unit 112 and the second proximity wireless communication unit 212 wait in a sleep operation or a deep sleep operation. If there is a power supply, a normal clock to be used at the time of communication execution is supplied instead of power supply.

通信装置２では、ステップＳ３０５の後、第２近接通信確立要求監視部２３２４は、対向する通信装置１から送信された第２近接無線通信の接続要求を、第２近接無線通信部２１２を介して受信したかどうかを判定する（ステップＳ３１０）。   In the communication device 2, after step S <b> 305, the second proximity communication establishment request monitoring unit 2324 sends the connection request for the second proximity wireless communication transmitted from the facing communication device 1 via the second proximity wireless communication unit 212. It is determined whether it has been received (step S310).

ステップＳ３１０において、第２近接無線通信の接続要求を対向する通信装置１から受信していないと判定された場合(ステップＳ３１０；Ｎｏ)、ステップＳ３１０に遷移する。第２近接通信確立要求監視部２３２４は、対向する通信装置１から第２近接無線通信の接続要求を受信したかどうかの判定を再び行う（ステップＳ３１０）。   If it is determined in step S310 that the connection request for the second close proximity wireless communication is not received from the facing communication device 1 (step S310; No), the process proceeds to step S310. The second close proximity communication establishment request monitoring unit 2324 determines again whether or not a connection request for the second close proximity wireless communication has been received from the opposing communication device 1 (step S310).

一方、ステップＳ３１０において、第２近接無線通信の接続要求を対向する通信装置１から受信したと判定された場合(ステップＳ３１０；Ｙｅｓ)、ステップＳ３１１に遷移する。第２近接通信確立要求応答送信部２３２５は、対向する通信装置１から送信された第２近接無線通信の接続要求に対する応答を、第２近接無線通信部１１２を介して通信装置１に送信する（ステップＳ３１１）。   On the other hand, when it is determined in step S310 that the connection request for the second close proximity wireless communication is received from the facing communication device 1 (step S310; Yes), the process proceeds to step S311. The second proximity communication establishment request response transmission unit 2325 transmits a response to the connection request for the second proximity wireless communication transmitted from the opposing communication device 1 to the communication device 1 via the second proximity wireless communication unit 112 ( Step S311).

その後、第２近接無線通信の接続が完了し（ステップＳ３１２）、通信装置１における第２近接通信ネゴ処理制御部１３２７と通信装置２における第２近接通信ネゴ処理制御部２３２６とは、第２近接無線通信を行うために必要な情報の交換を行う（ステップＳ３１３）。その後、第２近接通信アプリ起動制御部２３２７は、ステップＳ３１３において通信装置１とやり取りした情報を使用して、第２近接無線通信を実行するためのアプリケーションを起動する（ステップＳ３１４）。   Thereafter, the connection of the second proximity wireless communication is completed (step S312), and the second proximity communication negotiation processing control unit 1327 in the communication device 1 and the second proximity communication negotiation processing control unit 2326 in the communication device 2 are in the second proximity. Information necessary for performing wireless communication is exchanged (step S313). Thereafter, the second proximity communication application activation control unit 2327 activates an application for executing the second proximity wireless communication by using the information exchanged with the communication device 1 in step S313 (step S314).

そして、第２近接無線通信を使用し、通信装置１と通信装置２とはデータの送受信を行う（ステップＳ３１５）。   Then, using the second proximity wireless communication, the communication device 1 and the communication device 2 perform data transmission / reception (step S315).

なお、本実施形態では、ステップＳ３１１とステップＳ３１２においてデータ送信側の通信装置１から接続要求を送出し、データ受信側の通信装置２は通信装置１からの接続要求を待機するように記載したが、通信装置２から接続要求を送出し、通信装置１は通信装置２からの接続要求を待機するようなシーケンスでも良い。また、通信装置１と通信装置２との両装置から接続要求を送出し、どちらか一方の通信装置が対向する通信装置からの接続要求を受信して接続待機側に回るというシーケンスでも良い。   In the present embodiment, the connection request is transmitted from the communication device 1 on the data transmission side in steps S311 and S312 and the communication device 2 on the data reception side waits for the connection request from the communication device 1. The communication apparatus 2 may send a connection request, and the communication apparatus 1 may wait for the connection request from the communication apparatus 2. Alternatively, a sequence in which a connection request is transmitted from both the communication device 1 and the communication device 2 and one of the communication devices receives a connection request from the opposite communication device and turns to the connection standby side may be used.

以上のように、データ送信側、受信側どちらの通信装置も、第２近接無線通信部への電力供給を停止して待機し、第２近接無線通信を使用したデータ通信を実行する場合のみ第２近接無線通信部への電力供給をすることができるため、第２近接無線通信部の省電力化を図ることが可能となる。   As described above, the communication device on both the data transmission side and the reception side stops only when the power supply to the second proximity wireless communication unit is stopped and waits, and performs data communication using the second proximity wireless communication. Since power can be supplied to the two close proximity wireless communication units, it is possible to save power in the second close proximity wireless communication unit.

また、データ受信側の通信装置に関しては、データ通信実行前のアプリ起動といった、ユーザ操作が一切不要なため、ユーザ利便性を向上することも可能である。   Further, regarding the communication device on the data receiving side, user operation such as application activation before executing data communication is not required at all, and user convenience can be improved.

(実施形態２)
実施形態１では、データ送信側、受信側のどちらの通信装置においても、２つの近接無線通信部を搭載している場合の工夫について記載したが、本実施形態ではデータ受信側の通信装置が第１の近接無線通信部を備えておらず第２の近接無線通信部のみを搭載している場合について述べる。 (Embodiment 2)
In the first embodiment, the idea of mounting two close proximity wireless communication units in both the data transmission side and the reception side communication devices has been described. However, in this embodiment, the data reception side communication device is the first communication device. A case will be described in which the first proximity wireless communication unit is not provided and only the second proximity wireless communication unit is mounted.

上記のようにデータ受信側の通信装置が第２の近接無線通信部のみを搭載している場合、図３に示した処理シーケンスでは、データ送信側の通信装置１は、第２近接無線通信部起動完了コマンド（ステップＳ３０５）をデータ受信側の通信装置２から受信できず、通信装置２に対して第２近接無線通信部起動要求（ステップＳ３０７）を送信できない。   As described above, when the communication device on the data receiving side includes only the second proximity wireless communication unit, in the processing sequence illustrated in FIG. 3, the communication device 1 on the data transmission side is the second proximity wireless communication unit. The activation completion command (step S305) cannot be received from the communication device 2 on the data receiving side, and the second proximity wireless communication unit activation request (step S307) cannot be transmitted to the communication device 2.

そこで、通信装置１では第２近接無線通信部起動要求を送信後(ステップＳ３０１)、タイマーを使用して一定時間Ｔ１内に第２近接通信部起動完了コマンド（ステップＳ３０５）を通信装置２から受信できない場合は、通信装置２に対して第２近接無線通信部起動要求（ステップＳ３０７）を送信するなどの解決方法が考えられる。   Therefore, after transmitting the second proximity wireless communication unit activation request (step S301), the communication device 1 receives a second proximity communication unit activation completion command (step S305) from the communication device 2 within a predetermined time T1 using a timer. If this is not possible, a solution such as transmitting a second proximity wireless communication unit activation request (step S307) to the communication device 2 is conceivable.

しかし、上記解決方法では、通信装置２が第１の近接無線通信手段を搭載していない場合、タイマーＴ１の期間、第２近接無線通信の通信開始が遅延することとなり、ユーザ利便性を損なう可能性がある。   However, in the above solution, if the communication device 2 is not equipped with the first proximity wireless communication means, the start of communication of the second proximity wireless communication is delayed during the period of the timer T1, which may impair user convenience. There is sex.

本実施形態では、データ受信側の通信装置における第１の近接無線通信手段の搭載有無に関わらず、第２近接無線通信の迅速な開始を可能とするための、第２の近接無線通信手段の通信開始時における起動方法について説明する。   In this embodiment, the second proximity wireless communication means for enabling the rapid start of the second proximity wireless communication regardless of whether or not the first proximity wireless communication means is installed in the communication device on the data receiving side. A starting method at the start of communication will be described.

まず、通信装置の構成について述べる。データを送信する側の通信装置１の構成は図１と同等であるため、説明を省略する。   First, the configuration of the communication device will be described. The configuration of the communication device 1 on the data transmission side is the same as that in FIG.

データを受信する側の通信装置の構成を図４に示す。図４に示す通信装置４の構成は、図２に示す通信装置２と比べ、第１近接無線通信部２１１とそれに関連する処理部を取り除いたものであり、新規に追加された処理部はない。よって、図２と同等の部分には同じ符号を付し、説明は省略する。なお、図２と異なる符号を付している通信部４１は、図２で説明したものと同等の機能を持つ処理部を搭載しているが、今後説明を行う上で図２の処理部との違いを明確にするため、異なる番号を付すこととする。   FIG. 4 shows the configuration of the communication device on the data receiving side. The configuration of the communication device 4 illustrated in FIG. 4 is obtained by removing the first proximity wireless communication unit 211 and the processing unit related thereto as compared with the communication device 2 illustrated in FIG. 2, and there is no newly added processing unit. . Therefore, the same parts as those in FIG. In addition, although the communication part 41 which attached | subjected the code | symbol different from FIG. 2 is mounted with the process part which has a function equivalent to what was demonstrated in FIG. 2, in the future description, the process part of FIG. In order to clarify the difference, a different number is assigned.

続いて、図５のフローチャートを参照して、本発明の実施形態２における２台の通信装置が近接無線通信を使用してデータ送受信を開始する前の、データ送信側の通信装置１における省電力制御部１３２の動作について説明する。   Next, with reference to the flowchart of FIG. 5, power saving in the communication device 1 on the data transmission side before the two communication devices in the second embodiment of the present invention start data transmission / reception using close proximity wireless communication. The operation of the control unit 132 will be described.

本フローチャートはデータ送信側の通信装置１に対して電源が投入されることによって開始される。なお、通信装置１の起動後、通信装置１の第２近接無線通信部１１２は電源を供給せずに待機させる。上記以外に、通信実行時よりも低いクロックを供給して動作させるスリープ動作や、クロックの供給を停止するディープスリープ動作、のいずれかの動作状態で待機させるようにしても良い。このような動作状態にすることで第２近接無線通信部１１２の省電力化を図ることが可能となり、電源供給を停止する方法とほぼ同様の効果を得ることが可能である。   This flowchart is started when the communication apparatus 1 on the data transmission side is turned on. Note that after the communication device 1 is activated, the second close proximity wireless transfer unit 112 of the communication device 1 waits without supplying power. In addition to the above, the operation may be waited in any one of a sleep operation in which a clock lower than that at the time of communication execution is operated and a deep sleep operation in which the clock supply is stopped. By making such an operating state, it is possible to save power in the second close proximity wireless transfer unit 112, and it is possible to obtain substantially the same effect as the method of stopping power supply.

まず、第２近接通信開始要求監視部１３２１は、自通信装置１が備える第２近接通信アプリ１４１の起動後の、第２近接無線通信部１１２を使用した通信の開始要求があるかどうかを判定する（ステップＳ５００）。   First, the second proximity communication start request monitoring unit 1321 determines whether there is a request to start communication using the second proximity wireless communication unit 112 after the activation of the second proximity communication application 141 included in the communication device 1. (Step S500).

ステップＳ５００において、第２近接無線通信部１１２を使用した通信の開始要求がないと判定された場合(ステップＳ５００；Ｎｏ)は、ステップＳ５００に遷移する。第２近接無線通信開始要求監視部１３２１は、第２近接無線通信部１１２を使用した通信の開始要求があるかどうかの判定を再び行う（ステップＳ５００）。   When it is determined in step S500 that there is no request for starting communication using the second close proximity wireless transfer unit 112 (step S500; No), the process proceeds to step S500. The second close proximity wireless transfer start request monitoring unit 1321 determines again whether there is a start request for communication using the second close proximity wireless transfer unit 112 (step S500).

一方、ステップＳ５００において、第２近接無線通信部１１２を介した通信の開始要求があると判定された場合(ステップＳ５００；Ｙｅｓ)は、ステップＳ５０１に遷移する。ターゲット第２近接通信起動要求送信部１３２２は、対向する通信装置４が備える第２近接無線通信部４１２の起動要求を、第１近接無線通信部１１１を介して、通信装置４に対し送信する（ステップＳ５０１）。   On the other hand, if it is determined in step S500 that there is a request to start communication via the second close proximity wireless transfer unit 112 (step S500; Yes), the process proceeds to step S501. The target second proximity communication activation request transmission unit 1322 transmits an activation request for the second proximity wireless communication unit 412 included in the facing communication device 4 to the communication device 4 via the first proximity wireless communication unit 111 ( Step S501).

そして、第２近接通信起動制御部２３２２は、電源コントローラ１２１を介して第２近接無線通信部４１２に対して電源供給を開始して、第２近接無線通信部４１２を起動する（ステップＳ５０２）。なお、通信装置１が備える第２近接無線通信部１１２が、スリープ動作またはディープスリープ動作で待機している場合は、電源供給ではなく、通信実行時に使用すべき通常のクロックを供給することとする。   Then, the second close proximity communication activation control unit 2322 starts supplying power to the second close proximity wireless communication unit 412 via the power supply controller 121 and activates the second close proximity wireless communication unit 412 (step S502). When the second proximity wireless communication unit 112 included in the communication device 1 is on standby in a sleep operation or a deep sleep operation, a normal clock to be used when executing communication is supplied instead of supplying power. .

そして、第２近接無線通信部４１２の起動後、第２近接通信確立要求送信部１３２５は、第２近接無線通信の接続要求を、第２近接無線通信部１１２を介して通信装置４に対し送信する（ステップ５０３）。   After the activation of the second proximity wireless communication unit 412, the second proximity communication establishment request transmission unit 1325 transmits a connection request for the second proximity wireless communication to the communication device 4 via the second proximity wireless communication unit 112. (Step 503).

その後、ターゲット第２近接通信起動判定部１３２３は、第２近接無線通信部４１２の起動要求に対する応答を、通信装置４から第１近接無線通信部１１１を介して受信したかどうかの判定を行う（ステップＳ５０４）。   Thereafter, the target second near field communication activation determining unit 1323 determines whether a response to the activation request from the second near field wireless communication unit 412 has been received from the communication device 4 via the first near field communication unit 111 ( Step S504).

ステップＳ５０４において、第２近接無線通信部４１２の起動要求に対する応答を受信していないと判定された場合(ステップＳ５０４；Ｎｏ)、ステップＳ５０６に遷移する。第２近接通信確立要求応答監視部１３２６は、ステップＳ５０３にて送信された第２近接無線通信における通信路の接続要求に対する応答を、第２近接無線通信部１１２によって通信装置４から受信したかどうかを判定する（ステップＳ５０６）。   If it is determined in step S504 that a response to the activation request of the second close proximity wireless transfer unit 412 has not been received (step S504; No), the process proceeds to step S506. Whether the second close proximity communication establishment request response monitoring unit 1326 has received the response to the communication path connection request in the second close proximity wireless communication transmitted in step S503 from the communication device 4 by the second close proximity wireless communication unit 112. Is determined (step S506).

一方、ステップＳ５０４において、第２近接無線通信部４１２の起動要求に対する応答を受信したと判定された場合(ステップＳ５０４；Ｙｅｓ)、ステップＳ５０５に遷移する。第２近接通信確立要求送信部１３２５は、第２近接無線通信の接続要求を、第２近接無線通信部１１２を介して通信装置４に対し送信する（ステップＳ５０５）。その後、ステップＳ５０６に遷移して前述した判定処理を行う。   On the other hand, when it determines with having received the response with respect to the starting request | requirement of the 2nd proximity wireless communication part 412 in step S504 (step S504; Yes), it changes to step S505. The second proximity communication establishment request transmission unit 1325 transmits a connection request for the second proximity wireless communication to the communication device 4 via the second proximity wireless communication unit 112 (step S505). Thereafter, the process proceeds to step S506 and the above-described determination process is performed.

ステップＳ５０６において、第２近接無線通信の接続開始に対する応答を受信していないと判定された場合(ステップＳ５０６；Ｎｏ)、ステップＳ５０４に遷移する。ターゲット第２近接通信起動判定部１３２３は、通信装置４の第２近接無線通信部４１２の起動要求に対する応答を受信したかどうかの判定処理を再び行う（ステップＳ５０４）。   If it is determined in step S506 that a response to the connection start of the second close proximity wireless communication is not received (step S506; No), the process proceeds to step S504. The target second near field communication activation determination unit 1323 performs the determination process again to determine whether a response to the activation request for the second near field communication unit 412 of the communication device 4 has been received (step S504).

一方、ステップＳ５０６において、第２近接無線通信の通信路の確立要求に対する応答を受信したと判定された場合(ステップＳ５０６；Ｙｅｓ)、第２近接無線通信の通信路が確立される（ステップＳ５０７）。両通信装置１及び４は、第２近接無線通信を行うために必要な情報の交換後、データの送受信を行う。   On the other hand, when it is determined in step S506 that a response to the request for establishment of the communication path for the second proximity wireless communication has been received (step S506; Yes), the communication path for the second proximity wireless communication is established (step S507). . Both communication apparatuses 1 and 4 exchange data after exchanging information necessary for performing the second proximity wireless communication.

以上、本実施形態２に示したように、第２近接無線通信を開始する際、データ受信側の通信装置が備える第２近接無線通信部の起動要求と、第２近接無線通信の接続開始要求との、２つの要求を同時に対向するデータ受信側の通信装置へ送出するようにすることで、対向のデータ受信側の通信装置における第１の近接無線通信手段の搭載有無に関わらず、通信待機時の第２近接無線通信部の省電力化を図りながら、第２近接無線通信の迅速な開始が可能となるためユーザ利便性を向上することができる。   As described above, as shown in the second embodiment, when starting the second proximity wireless communication, the activation request for the second proximity wireless communication unit included in the communication device on the data reception side and the connection start request for the second proximity wireless communication are provided. The two requests are simultaneously sent to the opposite data receiving communication device, so that the communication standby can be performed regardless of whether the first proximity wireless communication means is installed in the opposite data receiving communication device. At the same time, the second proximity wireless communication unit can be started quickly and the second proximity wireless communication can be started quickly, so that the user convenience can be improved.

(実施形態３)
実施形態１において、通信装置１の第１近接無線通信部１１１及び通信装置２の第１近接無線通信部２１１には常時電力が供給されている場合について説明したが、第１近接無線通信部１１１及び２１１は、例えば決済など他のサービスでも使用されるため、セキュリティの観点よりユーザ設定に応じて、第１近接無線通信部１１１及び２１１の使用を許可しないようにする機能を有している場合がある。 (Embodiment 3)
In Embodiment 1, although the case where electric power was always supplied to the 1st near field communication part 111 of the communication apparatus 1 and the 1st near field communication part 211 of the communication apparatus 2 was demonstrated, the 1st near field communication part 111 And 211 are also used for other services such as payment, for example, and therefore have a function that does not permit the use of the first proximity wireless communication units 111 and 211 according to user settings from the viewpoint of security. There is.

なお、サービスを一時的に使用不可とする方法としては、送信側の通信装置１における第１近接無線通信部１１１への電源供給を停止するか、電源供給は常時行い第２近接無線通信起動要求を表すコマンド以外は全て無視する(全てエラーとして返すか破棄するなど)方法の２つが考えられる。   As a method for temporarily disabling the service, the power supply to the first proximity wireless communication unit 111 in the communication apparatus 1 on the transmission side is stopped or the power supply is always performed and the second proximity wireless communication activation request is made. There are two possible ways of ignoring all but the command that represents (all returned as an error or discarded).

上記２つの方法のうち、データ受信側の通信装置２においてユーザ設定により一時的に第１近接無線通信部２１１への電力供給を停止しているようなケースでは、データ送信側の通信装置１からの第２近接無線通信部２１１の起動要求を、第１近接無線通信部１１１を介して受信することができない。そこで、本実施形態では、第１近接無線通信部への電力供給有無に応じた第２近接無線通信部の省電力化制御方法について説明する。   Of the above two methods, in the case where the power supply to the first proximity wireless communication unit 211 is temporarily stopped by the user setting in the communication device 2 on the data reception side, the communication device 1 on the data transmission side The activation request for the second proximity wireless communication unit 211 cannot be received via the first proximity wireless communication unit 111. Therefore, in the present embodiment, a power saving control method for the second proximity wireless communication unit according to whether power is supplied to the first proximity wireless communication unit will be described.

まず、図６に本実施形態３に係るデータを送信する側の通信装置６の構成を示し、図７に本発明の実施形態３に係るデータを受信する側の通信装置７の構成を示す。   First, FIG. 6 shows the configuration of the communication device 6 on the data transmission side according to the third embodiment, and FIG. 7 shows the configuration of the communication device 7 on the data reception side according to the third embodiment of the present invention.

なお、図６において図１と同等の部分については同じ符号を付し、図７において図２と同等の部分については同じ符号を付し、それぞれ説明を省略する。また、図６において、図１と異なる符号を付している通信部６１は、図１で説明したものと同等の機能を持つ処理部を搭載しているが、今後説明を行う上で図１の処理部との違いを明確にするため、異なる番号を付すこととする。   6, the same reference numerals are given to the same parts as those in FIG. 1, and the same reference numerals are given to the same parts in FIG. 7 as those in FIG. 2, and description thereof will be omitted. In FIG. 6, the communication unit 61 denoted by a reference numeral different from that in FIG. 1 is equipped with a processing unit having the same function as that described in FIG. In order to clarify the difference from the processing unit, a different number is assigned.

さらに、図７において、図２と異なる符号を付している通信部７１は、図２で説明したものと同等の機能を持つ処理部を搭載しているが、今後説明を行う上で図２の処理部との違いを明確にするため、異なる番号を付すこととする。   Further, in FIG. 7, a communication unit 71 denoted by a reference numeral different from that in FIG. 2 is equipped with a processing unit having a function equivalent to that described in FIG. In order to clarify the difference from the processing unit, a different number is assigned.

以下、図１及び図２と同等でない省電力制御部６３１及び７３１において、新たに追加された第１近接通信動作状態読出部６３２１、第１近接通信動作判定部６３２２、第１近接通信動作変更監視部６３２３について説明する。なお、本実施形態の通信部６１及び７１に関する説明は、図６と図７で同等のため、図６を使用して行う。   Hereinafter, in the power saving control units 631 and 731 that are not equivalent to those in FIG. 1 and FIG. 2, newly added first proximity communication operation state reading unit 6321, first proximity communication operation determination unit 6322, first proximity communication operation change monitoring The part 6323 will be described. In addition, since the description regarding the communication parts 61 and 71 of this embodiment is equivalent in FIG. 6 and FIG. 7, it performs using FIG.

第１近接通信動作状態読出部６３２１は、通信装置６への電源投入後に記憶１４に記憶されている第１近接無線通信部６１１の動作状態情報を読み出す。なお、第１近接無線通信部６１１の動作状態情報とは、第１近接無線通信部６１１に対して電源が供給されているかどうかを表す情報である。   The first proximity communication operation state reading unit 6321 reads the operation state information of the first proximity wireless communication unit 611 stored in the storage 14 after the communication device 6 is powered on. The operation state information of the first proximity wireless communication unit 611 is information indicating whether power is supplied to the first proximity wireless communication unit 611.

第１近接通信動作判定部６３２２は、第１近接無線通信部６１１に対して電源が供給されているかどうかを判定する。   The first proximity communication operation determination unit 6322 determines whether power is supplied to the first proximity wireless communication unit 611.

第１近接通信動作変更監視部６３２３は、第１近接無線通信部６１１に対する電源供給の有無が変更されたかどうかを監視する。   The first proximity communication operation change monitoring unit 6323 monitors whether or not the power supply to the first proximity wireless communication unit 611 has been changed.

続いて、図８のフローチャートを参照して、本実施形態における第１近接無線通信部６１１への電力供給の有無に応じた第２近接無線通信部６１２の省電力化制御について説明する。   Next, power saving control of the second proximity wireless communication unit 612 according to the presence or absence of power supply to the first proximity wireless communication unit 611 in the present embodiment will be described with reference to the flowchart of FIG.

本フローチャートは、通信装置６または７に対して電源が投入されたことにより開始される。   This flowchart is started when the communication device 6 or 7 is powered on.

まず、第１近接通信動作状態読出部６３２１は記憶部１４に記憶されている第１近接無線通信部６１１の動作状態情報を読み出す（ステップＳ８００）。   First, the first proximity communication operation state reading unit 6321 reads the operation state information of the first proximity wireless communication unit 611 stored in the storage unit 14 (step S800).

そして、第１近接通信動作判定部６３２２は、第１近接無線通信部６１１に対して電源が供給されているかどうかを判定する（ステップＳ８０１）。   Then, the first proximity communication operation determination unit 6322 determines whether power is supplied to the first proximity wireless communication unit 611 (step S801).

ステップＳ８０１において、第１近接無線通信部６１１に対して電源が供給されていると判定された場合(ステップＳ８０１；Ｙｅｓ)は、ステップＳ８０２に遷移する。第２近接通信起動制御部１３２４は、電源コントローラ１２１を制御して、第２近接無線通信部６１２への電源供給を停止する（ステップＳ８０２）。   If it is determined in step S801 that power is supplied to the first proximity wireless communication unit 611 (step S801; Yes), the process proceeds to step S802. The second proximity communication activation control unit 1324 controls the power supply controller 121 to stop the power supply to the second proximity wireless communication unit 612 (step S802).

なお、ここで、通信実行時よりも低いクロックを供給して動作させるスリープ動作や、クロックの供給を停止するディープスリープ動作、のいずれかの動作状態で待機させるようにしても良い。このような動作状態にすることで第２近接無線通信部６１２の省電力化を図ることが可能となり、電源供給を停止する方法とほぼ同様の効果を得ることが可能である。   Here, the operation may be waited in any one of a sleep operation in which a clock lower than that in communication execution is operated and a deep sleep operation in which the clock supply is stopped. By making such an operating state, it is possible to save power in the second close proximity wireless transfer unit 612, and it is possible to obtain substantially the same effect as the method of stopping power supply.

一方、ステップＳ８０１において、第１近接無線通信部６１１に対して電源が供給されていないと判定された場合(ステップＳ８０１；Ｎｏ)は、ステップＳ８０３に遷移する。第２近接通信起動制御部１３２４は、電源コントローラ１２１を制御して、第２近接無線通信部６１２への電源供給を開始する（ステップＳ８０３）。
なお、ここで、通信装置６が備える第２近接無線通信部６１２が、スリープ動作またはディープスリープ動作で待機している場合は、通信実行時に使用すべき通常のクロックを供給することとする。 On the other hand, if it is determined in step S801 that power is not supplied to the first proximity wireless communication unit 611 (step S801; No), the process proceeds to step S803. The second close proximity communication activation control unit 1324 controls the power supply controller 121 to start supplying power to the second close proximity wireless transfer unit 612 (step S803).
Here, when the second proximity wireless communication unit 612 included in the communication device 6 is on standby in the sleep operation or the deep sleep operation, a normal clock to be used during communication execution is supplied.

ステップＳ８０２、及びステップＳ８０３の処理終了後、ステップＳ８０４に遷移する。第１近接通信動作変更監視部６３２３は、第１近接無線通信部６１１に対する電源供給の有無が変更されたかどうかを判定する（ステップＳ８０４）。   After the processing of step S802 and step S803 is completed, the process proceeds to step S804. The first proximity communication operation change monitoring unit 6323 determines whether or not the power supply to the first proximity wireless communication unit 611 has been changed (step S804).

ステップＳ８０４において、第１近接無線通信部６１１に対する電源供給の有無が変更されていないと判定された場合(ステップＳ８０４；Ｎｏ)、第１近接通信動作変更監視部６３２３は、第１近接無線通信部６１１に対する電源供給の有無が変更されたかどうかの判定処理を再び行う（ステップＳ８０４）。   When it is determined in step S804 that the presence or absence of power supply to the first proximity wireless communication unit 611 has not been changed (step S804; No), the first proximity communication operation change monitoring unit 6323 has the first proximity wireless communication unit. The process of determining whether or not the power supply to 611 has been changed is performed again (step S804).

一方、ステップＳ８０４において、第１近接無線通信部６１１に対する電源供給の有無が変更されたと判定された場合(ステップＳ８０４；Ｙｅｓ)、ステップＳ８０１に遷移する。第１近接通信動作判定部６３２２は、第１近接無線通信部６１１に対して電源が供給されているかどうかを判定する（ステップＳ８０１）。ステップＳ８０１以降の処理は上述した通りである。   On the other hand, when it is determined in step S804 that the presence / absence of power supply to the first proximity wireless communication unit 611 has been changed (step S804; Yes), the process proceeds to step S801. The first proximity communication operation determination unit 6322 determines whether power is supplied to the first proximity wireless communication unit 611 (step S801). The processing after step S801 is as described above.

以上、本実施形態に示したように、第１近接無線通信部６１１への電力供給の有無に応じて第２近接無線通信部６１２への電力供給を制御することで、第１近接無線通信部６１１への電力供給をユーザ設定により一時的に停止しているような場合においても、第２近接無線通信部６１２の省電力化を図りつつ、ユーザは対向のデータ受信側の通信装置７における第２近接無線通信部７１２の通電の有無を意識すること無くデータ通信を実行可能なため、ユーザに対して利便性の高いサービスを提供できる。   As described above, as shown in the present embodiment, the first proximity wireless communication unit is controlled by controlling the power supply to the second proximity wireless communication unit 612 according to the presence or absence of the power supply to the first proximity wireless communication unit 611. Even when the power supply to 611 is temporarily stopped by the user setting, the user can save power in the second proximity wireless communication unit 612, and the user can change the power in the communication device 7 on the opposite data reception side. Since data communication can be executed without being aware of whether the 2-proximity wireless communication unit 712 is energized, a highly convenient service can be provided to the user.

なお、本実施形態では、ユーザ設定により一時的に第１近接無線通信部６１１への電力供給を停止するように要求された場合、第２近接無線通信部６１２への電力供給を開始する制御方法を記載したが、表示部１５を通じ、図９に示すような通知をユーザに行うことで、第２近接無線通信部６１２への電力供給を行わないように制御しても良い。   In the present embodiment, when it is requested to temporarily stop the power supply to the first proximity wireless communication unit 611 according to the user setting, the control method of starting the power supply to the second proximity wireless communication unit 612 However, it may be controlled not to supply power to the second close proximity wireless transfer unit 612 by notifying the user through the display unit 15 as shown in FIG.

そうすることで、通信待機時は、第１近接無線通信部６１１への電力供給の有無に関わらず、第２近接無線通信部６１２には電力供給を行わないため、第２近接無線通信部６１２の更なる省電力化を図ることができる。   By doing so, since power is not supplied to the second proximity wireless communication unit 612 regardless of whether power is supplied to the first close proximity wireless communication unit 611 during communication standby, the second close proximity wireless communication unit 612 does not supply power. Further power saving can be achieved.

なお、本発明は上記実施の形態に限定されず、種々の変形及び応用が可能である。   In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible.

通信部１１等が備える第１近接無線通信部１１１及び第２近接無線通信部１１２の２種類に限定されず、第ｎ近接無線通信部まで拡張することができる。その場合、最も通信レートが高い近接無線通信部を介して無線通信を行うこともできる。また、バッテリ１２２の残量に応じて、使用する近接無線通信部を変更することもできる。例えば、バッテリ１２２の残量が多い場合には、消費電力を考慮せずに通信レートが高い近接無線通信部によって無線通信を行うこともでき、バッテリ１２２の残量が少ない場合には、消費電力が少ない近接無線通信部によって無線通信を行うこともできる。   The first proximity wireless communication unit 111 and the second proximity wireless communication unit 112 included in the communication unit 11 and the like are not limited to two types, and can be extended to the nth proximity wireless communication unit. In that case, wireless communication can also be performed via the proximity wireless communication unit having the highest communication rate. Further, the proximity wireless communication unit to be used can be changed according to the remaining amount of the battery 122. For example, when the remaining amount of the battery 122 is large, wireless communication can be performed by the proximity wireless communication unit having a high communication rate without considering the power consumption. When the remaining amount of the battery 122 is small, the power consumption Wireless communication can also be performed by a close proximity wireless communication unit with a small amount.
