Description

  The present invention relates to a communication method, an information processing apparatus, and a program.

  In recent years, information processing apparatuses capable of wireless communication using a frequency hopping spread spectrum, such as IEEE 802.15.1 (sometimes referred to as “Bluetooth” (registered trademark)), are becoming widespread. For example, when using a communication technology based on a frequency hopping method such as IEEE802.15.1, even if there is an obstacle between the devices, communication can be performed as long as the radio wave reaches. Thus, for example, IEEE 802.15.1 is a communication between a mobile phone (an example of an information processing device) and a headset (an example of an information processing device) for realizing hands-free calling, or a PC (Personal Computer. Information). It is used for communication between an example of a processing device and an operation device such as a keyboard. For example, when using a communication technology based on a frequency hopping method such as IEEE802.15.1, it is possible to reduce power consumption related to communication in the information processing apparatus more than when using another communication technology. Therefore, an information processing apparatus capable of wireless communication using a communication technique based on a frequency hopping method such as IEEE802.15.1 has been widely used.

Communication takes place. Here, the master device is an information processing device that plays a role of determining a frequency hopping pattern related to communication in a wireless communication network, for example. A slave device refers to an information processing device that performs communication in synchronization with a frequency hopping pattern determined by a master device in a wireless communication network, for example. As described above, one information processing device among the plurality of information processing devices functions as a master device, and the other information processing devices function as slave devices. A star-type wireless communication network N10 is realized by the processing device. Here, FIG. 1 is an explanatory diagram illustrating an example of a star-type wireless communication network, and an example of a wireless communication network in which the information processing device 10A functions as a master device and the information processing devices 10B to 10D function as slave devices. Is shown.

  Under such circumstances, a technique for adding a new information processing apparatus to the wireless communication network as an information processing apparatus constituting the wireless communication network has been developed. As a technology for selectively adding an information processing apparatus newly connected using a multi-hop technique as an information processing apparatus constituting a wireless communication network, for example, Patent Document 1 is disclosed. Can be mentioned.

  In recent years, information processing apparatuses capable of wireless communication using a communication technique based on a frequency hopping method such as IEEE802.15.1 have become more and more multifunctional. Among the information processing apparatuses, those having an entertainment function such as correspondence to a game using wireless communication have appeared in addition to the original functions of the information processing apparatus. Examples of the information processing apparatus include a mobile phone corresponding to a game using wireless communication in addition to the original functions such as a call and mail.

  Here, as shown in FIG. 1, a plurality of information processing apparatuses 10 </ b> A to 10 </ b> D (hereinafter sometimes collectively referred to as “information processing apparatus 10”) has one star-type wireless communication network (hereinafter “ Sometimes referred to as a “star network” or “network.”) In the case of being configured by N10, each information processing apparatus 10 can communicate via the master apparatus 10A.

  Also, communication between information processing apparatuses belonging to different networks can be realized by constructing a network in which a plurality of networks are connected (hereinafter, referred to as “scatternet”). FIG. 2 is an explanatory diagram illustrating an example of a scatternet. Here, FIG. 2 shows a network N11 composed of the information processing device 10A and the information processing device 10D, and a network N12 composed of the information processing device 10B and the information processing device 10C, and the information processing device 10A and the information processing device 10C. An example of connection by a network N12 consisting of 2 shows an example in which the information processing apparatus 10A serves as a master apparatus in the network N11 and the network N13, and the information processing apparatus 10C serves as a master apparatus in the network N12. By constructing a scatternet as shown in FIG. 2, for example, communication between the information processing apparatus 10B and the information processing apparatus 10D shown in FIG. 2, that is, communication between information processing apparatuses belonging to different networks is realized. be able to.

  However, when communication between information processing apparatuses is realized by a scatternet, information processing that requires processing related to communication in each of a plurality of networks, such as the information processing apparatuses 10A and 10C shown in FIG. A device is required. Therefore, when communication between information processing devices belonging to different networks is realized by a scatternet, an excessive load is applied to some information processing devices constituting the scatternet, resulting in a decrease in throughput or overload. There is a risk of unintentional communication failure such as interruption of communication due to.

  Further, in the case where communication between information processing apparatuses is realized by a scatternet, when a packet is transmitted from one information processing apparatus in the scatternet to an arbitrary information processing apparatus, the transfer path of the packet is a scatternet. The complexity increases as the number of networks in the net increases. More specifically, the number of combinations of transfer paths increases exponentially as the number of networks in the scatternet increases. Therefore, processing related to communication in each information processing device in the scatternet becomes more complex as the number of networks increases, which may cause unintentional communication failures such as a decrease in throughput or communication interruption due to overload. is there.

  As described above, when communication between information processing apparatuses is realized by a scatternet, there is a possibility that an unintended communication failure may occur. Therefore, stabilization of communication cannot be expected. Further, in view of the complexity of processing related to the communication, application software using communication between information processing apparatuses such as a game using wireless communication, which functions on a scatternet (hereinafter referred to as “application”). .) Is difficult to achieve. Therefore, a new communication method capable of performing more stable communication between information processing apparatuses belonging to different star-type networks without constructing a scatternet, and an information processing apparatus for realizing the communication method Was sought after.

  Here, in the conventional technique of adding a new information processing apparatus to the network as an information processing apparatus constituting the network (hereinafter referred to as “conventional technique”), the information processing apparatus to be connected to the network is connected to the network. It communicates with the proxy authentication device which comprises. In the conventional technique, the proxy authentication device authenticates the information processing device to be connected to the network by performing authentication with the master authentication device in the network. Therefore, there is a possibility that a new information processing apparatus can be selectively added to the network by using the conventional technique.

  However, the conventional technique is a technique for performing authentication of an information processing apparatus to be connected as described above between a proxy apparatus and a master authentication apparatus configuring a network. Therefore, even if the information processing device that is to be connected to the network is an information processing device that constitutes another network other than the network, the information processing device that is to be connected is simply added to the network to be connected. It is only done. That is, even if the conventional technique is used, only a plurality of networks are connected via the information processing apparatus to be connected, and the same result as that of the scatternet shown in FIG. 2 is obtained.

  Therefore, even if the conventional technique is used, an unintended communication failure may occur as in the case of the scatternet, and stabilization of communication cannot be expected. In addition, even in the case of using the conventional technology, as in the case of a scatternet, a game using wireless communication between information processing devices that function on a network and configure different networks, for example, a game using wireless communication, etc. There is no way to realize this application.

  Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

In the following, description will be given in the following order.
1. 1. Communication method according to an embodiment of the present invention 2. Information processing apparatus according to an embodiment of the present invention Program according to the embodiment of the present invention

(Communication method according to an embodiment of the present invention)
Before describing the configuration of an information processing apparatus according to an embodiment of the present invention, a communication method according to an embodiment of the present invention will be described.

[Communication Stabilization Approach According to Embodiment of the Present Invention]
As described above, communication between information processing apparatuses belonging to different networks can be realized by a scatternet connecting a plurality of star-type networks, but an unintended communication failure may occur. There is a risk that processing related to communication may become complicated. Even if the conventional technique is used, an unintended communication failure may occur as in the case of a scatternet, and the processing related to communication may be complicated.

  Therefore, in the embodiment of the present invention, a plurality of star networks are integrated into one star network. Here, by integrating a plurality of star-type networks into one star-type network, communication between information processing apparatuses belonging to different networks before the integration is equivalent to the state shown in FIG. . The embodiment of the present invention focuses on the above, and integrates a plurality of star networks into a single star network, thereby including communication between information processing apparatuses belonging to different star networks. The communication between any information processing apparatuses constituting the connected network is stabilized.

  Here, as the star network according to the embodiment of the present invention, for example, a star network in which a plurality of information processing apparatuses are connected using a communication technique based on a frequency hopping method such as IEEE802.15.1. It is done. In the following, a case where communication between information processing apparatuses in a star network according to an embodiment of the present invention is communication using IEEE 802.15.1 will be described as an example. Communication between information processing apparatuses in such a network is not limited to the above. For example, in the star network according to the embodiment of the present invention, communication between information processing apparatuses can be realized by any communication that can form a star network by a frequency hopping method. In the following, IEEE 802.15.1 may be expressed as “BT”.

  By integrating a plurality of star-type networks into one star-type network, communication between arbitrary information processing apparatuses constituting the integrated network is performed via, for example, a master apparatus as shown in FIG. Done. In other words, for an integrated network, an information processing apparatus that must perform processing related to communication in each of a plurality of networks, as in the case of a scatternet as shown in FIG. not exist. Therefore, in the integrated network according to the embodiment of the present invention, it is possible to further reduce the possibility of an unintended communication failure than in the case of a scatternet.

  In the embodiment of the present invention, since a plurality of star networks are integrated into one star network, the combination of packet transfer paths increases exponentially as in the case of a scatternet. There is nothing. Therefore, in the integrated network according to the embodiment of the present invention, the complexity of processing related to communication is reduced as compared with the case of the scatternet, so that an unintended communication failure may occur than in the case of the scatternet. Can be further reduced. Furthermore, by reducing the complexity of processing related to communication, it becomes easier to implement an application that uses communication between information processing apparatuses that function on the network, such as a game using wireless communication.

  Therefore, by using the communication stabilization approach according to the embodiment of the present invention, it is possible to reduce the possibility of the occurrence of the unintended communication failure. Therefore, between information processing apparatuses belonging to different star networks Communication between arbitrary information processing apparatuses including communication in the above can be performed more stably.

[Outline of processing related to communication stabilization approach]
Next, an overview of processing according to the communication stabilization approach of the embodiment of the present invention will be described. In the following, an outline of processing according to the communication stabilization approach of the embodiment of the present invention will be described by taking as an example a case where two star networks are integrated into one star network. Note that the number of star networks that can be integrated using the communication stabilization approach according to the embodiment of the present invention is not limited to two. For example, it is possible to integrate three or more star networks into one star network by repeating the process of integrating the following two star networks into one star network.

  3A to 3D are explanatory diagrams for describing an overview of processing according to the communication stabilization approach of the embodiment of the present invention. Here, FIG. 3A shows a state before network integration, and FIGS. 3B and 3C show states after network integration is started. FIG. 3D shows a state where the networks are integrated. In FIG. 3A to FIG. 3D, an information processing device that serves as a master device in the network is represented by “Mm” (m is a natural number), and an information processing device that serves as a slave device is represented by “Sn”. Hereinafter, the information processing apparatus 100 may be represented as “master apparatus Mm” or “slave apparatus Sn”.

(A) State before integration (FIG. 3A)
FIG. 3A shows a network N1 composed of information processing apparatuses 100A, 100B, and 100C and a network N2 composed of information processing apparatuses 100D, 100E, 100F, and 100G, respectively. Here, in the network N1, the information processing device 100A serves as a master device, and the information processing devices 100B and 100C serve as slave devices. In the network N2, the information processing apparatus 100D serves as a master apparatus, and the information processing apparatuses 100E, 100F, and 100G serve as slave apparatuses. Hereinafter, one of the networks N1 and N2 may be referred to as a “first network” and the other network may be referred to as a “second network”.

  Each of the information processing apparatuses 100A to 100F (hereinafter sometimes collectively referred to as “information processing apparatus 100”) configuring the networks N1 and N2 is different from other information processing apparatuses 100 using two different communication paths. Have a function of performing communication between them. Here, the significance of the information processing apparatus 100 having a function of performing communication with another information processing apparatus 100 using two different communication paths will be described.

<Significance of having a function of performing communication with another information processing apparatus 100 using two different communication paths of the information processing apparatus 100>
When a network is configured by communication between information processing apparatuses 100, generally, a faster and more secure communication method is required. Therefore, even when the information processing apparatuses 100 are connected by communication using IEEE802.15.1 to form a network, for example, IEEE802.15.1 communication settings (for example, address information, passcode, etc.), etc. It is necessary to make various connection settings. Here, when the user is forced to perform predetermined connection setting work for performing various connection settings as described above so that the information processing apparatuses 100 can communicate with each other, the convenience of the user is significantly reduced. End up.

  Therefore, in the embodiment of the present invention, setting information for enabling communication in the second communication path (described later) in the first communication path (described later) and the configuration of the network to which the own apparatus belongs. Is transmitted and received between the information processing apparatuses 100. An example of the setting information and network configuration information according to the embodiment of the present invention is shown in FIGS. 4 and 5 to be described later.

  Here, the first communication path is a communication that allows one-to-one communication between one information processing apparatus 100 and another information processing apparatus 100 without requiring special connection settings by the user. A communication path formed by the method. Examples of the first communication path according to the embodiment of the present invention include a communication path formed by NFC (Near Field Communication) using a magnetic field (carrier wave) of a predetermined frequency such as 13.56 MHz for communication. It is not limited to the above. For example, in the embodiment of the present invention, a communication path formed by infrared communication using infrared light for communication can be used as the first communication path.

  When the first communication path is a communication path formed by NFC, one information processing apparatus 100 plays a role as a reader / writer that mainly transmits a carrier wave. In the above case, the other information processing apparatus 100 receives the signal transmitted by the carrier wave from the one information processing apparatus 100 and performs load modulation according to the received signal, thereby performing the one information processing apparatus. A reply is sent to the device 100. One information processing apparatus 100 and another information processing apparatus 100 can perform communication through the first communication path by transmitting and receiving signals as described above, for example.

  In addition, the second communication path requires a predetermined connection setting for one-to-one communication between one information processing apparatus 100 and another information processing apparatus 100, but higher-speed communication is possible. This is a communication path formed by various communication methods. The second communication path corresponds to a communication path used for communication for configuring a star-type network using the frequency hopping method. Here, examples of the second communication path according to the embodiment of the present invention include wireless communication using IEEE 802.15.1, but are not limited thereto.

  In the embodiment of the present invention, each information processing apparatus 100 configuring a network has a function of communicating with another information processing apparatus 100 using two different communication paths, thereby improving user convenience. However, the information processing apparatuses 100 can be in a communicable state.

(B) First state related to network integration (FIG. 3B)
(B-1) Communication processing by first communication path When network integration is started, the first information processing apparatus 100 belonging to the network N1 and the other information processing apparatus 100 belonging to the network N2 Communication via the communication path is performed.

  FIG. 3B shows a first state where processing related to the integration of the network N1 and the network N2 is started, and the first communication is performed between the master device M1 of the network N1 and the master device M2 of the network N2. The state where the communication by the road is started is shown. Setting information and network configuration information are mutually transmitted and received between the master device M1 and the master device M2. Here, FIG. 3B shows an example in which the master device M1 (information processing device 100A) of the network N1 and the master device M2 (information processing device 100D) of the network N2 communicate via the first communication path. However, it is not limited to the above. In the following, the processing related to the communication stabilization approach of the embodiment of the present invention will be described by taking as an example the case where the master device M1 of the network N1 and the master device M2 of the network N2 communicate via the first communication path. To do. Other examples will be described later.

[Example of information transmitted / received through the first communication path]
FIG. 4 is an explanatory diagram illustrating a first example of information transmitted and received through the first communication path according to the embodiment of the present invention.

  The information according to the first example transmitted / received through the first communication path includes, for example, request information 180 for requesting communication according to the second communication path, setting information 182 and network configuration information 184.

  In the request information 180, for example, a RecordType for handover (for example, “Hr” or “Hs”) indicating that the message is for handover is stored. Here, handover refers to an act of switching from communication via the first communication path, which is the first communication means, to communication via the second communication path via the second communication means (second carrier). The information processing apparatus 100 receives the request information 180 on the first communication path, thereby grasping that the target of communication on the first communication path desires communication on the second communication path. Can do.

  The setting information 182 is information for connecting an external device via the second communication path, and includes a header 186 (BT setting) indicating the type of information, and a payload 188. In the payload 188, for example, address information (BD address) used for an external device to connect via the second communication path, and a passcode (authentication information; for example, random number) used for authentication to improve security. And a hash value are included, but are not limited to the above.

  When the information processing apparatus 100 transmits a passcode to another information processing apparatus 100 that performs communication through the second communication path, the same passcode is shared between the information processing apparatuses 100 belonging to different networks. . Therefore, the information processing apparatus 100 performs authentication using a passcode when communication is started on the second communication path, and selectively performs communication on the second communication path based on the authentication result. Therefore, security can be further improved. Here, the passcode can be a temporary passcode (temporary passcode) that can be normally authenticated for a certain period of time, but is not limited thereto. If authentication for improving security is not performed, passcode information (authentication information) may not be included in the setting information.

  The network configuration information 184 is information indicating the configuration of the network to which the information processing apparatus 100 that transmits the network configuration information 184 belongs, and includes a header 190 (network configuration information identifier) indicating the type of information, a payload 192, and the like. Consists of. The payload 190 includes, for example, designated role information (BT role information) and an external connection list, but is not limited to the above.

  Here, the designated role information according to the embodiment of the present invention is information (data) indicating a desired role (for example, other than master / master) in communication via the second communication path. For example, the information processing apparatus 100 uses, as the specified role information included in the network configuration information, information indicating the role played in the communication through the second communication path in the network to which the own apparatus belongs, but is not limited thereto. For example, the information processing apparatus 100 may set information indicating a role different from the role in the network to which the apparatus belongs to designated role information included in the network configuration information based on a user operation of the user of the information processing apparatus 100 or the like. it can. The designated role information transmitted by the information processing apparatus 100 is used for a role determination process (described later) in another information processing apparatus 100.

  The external connection list is setting information for the external device to communicate with other information processing devices 100 that configure the network to which the information processing device 100 belongs, other than the information processing device 100 that transmits the network configuration information. Information (data) including When the information processing apparatus 100 transmits the external connection list to another information processing apparatus 100 that communicates via the second communication path, the other information processing apparatus 100 belongs to another network. It is possible to communicate with the second communication path.

  The information shown in FIG. 4 is transmitted and received between the information processing apparatus 100A and the information processing apparatus 100D, whereby each of the information processing apparatuses 100A and 100D performs a second communication with the information processing apparatus 100 belonging to another network. It will be in the state which can communicate by this communication path. A specific process in the case of transmitting / receiving information according to the first example transmitted / received via the first communication path illustrated in FIG. 4 between the information processing apparatuses 100 will be described later.

  In addition, the information transmitted / received in the 1st communication path which concerns on embodiment of this invention is not restricted to the example shown in FIG. FIG. 5 is an explanatory diagram illustrating a second example of information transmitted / received through the first communication path according to the embodiment of the present invention.

  The information according to the second example transmitted / received through the first communication path includes, for example, request information 180, setting information 182 and network configuration information 194. Here, the request information 180 and the setting information 182 shown in FIG. 5 are the same information as the request information 180 and the setting information 182 according to the first example shown in FIG. 4, respectively.

  The network configuration information 184 includes a header 190 (network configuration information identifier) and a payload 196. The payload 196 includes, for example, designated role information and a subsequent list flag, but is not limited to the above. Here, the subsequent list flag according to the embodiment of the present invention is information (notification information) for notifying whether or not the external connection list is transmitted in the subsequent communication. As the subsequent list flag, for example, 1-bit data (for example, “0” indicates that the external connection list is not transmitted in the subsequent communication, and “1” indicates that the external connection list is transmitted in the subsequent communication. However, it is not limited to the above.

  When the information illustrated in FIG. 5 is transmitted and received between the information processing apparatus 100A and the information processing apparatus 100D through the first communication path, for example, the connection is enabled using the setting information illustrated in FIG. The external connection list is transmitted and received through the two communication paths. In addition, specific processing in the case of transmitting / receiving information according to the second example transmitted / received via the first communication path illustrated in FIG. 5 between the information processing apparatuses 100 will be described later.

  For example, the information illustrated in FIGS. 4 and 5 is transmitted and received between the information processing apparatus 100A and the information processing apparatus 100D by communication through the first communication path. Here, the process (B-1) can also be regarded as, for example, “a process related to the exchange of addresses and certificates” between the information processing apparatus 100A and the information processing apparatus 100D.

(B-2) Role Determination Process When the information shown in FIGS. 4 and 5 is transmitted and received through the first communication path by the process (B-1), for example, the information processing apparatus 100A and the information processing apparatus 100D A role determination process is performed to determine a role to be played in the communication via the second communication path in each network after integration. Here, the role determination process corresponds to a process in which the information processing apparatus 100 determines whether or not the own apparatus functions as a master apparatus in communication via the second communication path in the network after integration.

  More specifically, the information processing apparatus 100 performs a role determination process based on designated role information corresponding to the own apparatus, network configuration information received through the first communication path, and role arbitration information.

  Here, the information processing apparatus 100, for example, designates information indicating the role played in the communication via the second communication path in the network to which the own apparatus belongs (for example, information indicating the master / slave) corresponding to the own apparatus. The role information is not limited to the above. For example, the information processing apparatus 100 may set information indicating a role different from the role in the network to which the information processing apparatus 100 belongs to designated role information corresponding to the information processing apparatus 100 based on a user operation of the user of the information processing apparatus 100. it can.

  FIG. 6 is an explanatory diagram illustrating an example of role mediation information used in the role determination process by the information processing apparatus 100 according to the embodiment of the present invention. Here, FIG. 6 shows an example in which the role mediation information is represented in a table format, but the present invention is not limited to the above.

  Based on the designated role information (for example, the BT roll information shown in FIGS. 4 and 5) corresponding to the external device included in the network configuration information received on the first communication path, the information processing apparatus 100 The communication target information processing apparatus 100 (corresponding to the target apparatus in FIG. 6) that performs communication on the communication path grasps a desired role. Then, the information processing apparatus 100 applies the role of the target device grasped and the role desired by the own device grasped by the designated role information corresponding to the own device, for example, to the role arbitration information shown in FIG. The role played by the own device in the second communication path is determined.

  Here, for example, when the role desired by the own device matches the role desired by the target device, the information processing device 100 determines the number of connected external devices (“the number of information processing devices constituting the network”). -1 ″)) to determine the role. The information processing apparatus 100 uses the external connection list (in the case of FIG. 4) included in the network configuration information received in the first communication path, or the external connection list (in FIG. 5) received in the second communication path. The number of external devices connected to the target device can be determined. Note that when the external connection list is received through the second communication path (in the case of FIG. 5), for example, the target device temporarily serves as the master device, so that the information processing device 100 The external connection list can be acquired from the target device, but is not limited to the above.

  The information processing apparatus 100 can determine the role played in the communication through the second communication path in the network after integration by using, for example, the role arbitration information shown in FIG. Note that the role mediation information according to the embodiment of the present invention is not limited to the example shown in FIG. For example, the role mediation information according to the embodiment of the present invention includes information on conditions related to determining a role when the number of external devices connected to the own device matches the number of external devices connected to the target device. Further can be included. As the above condition, for example, “the information processing apparatus 100 serving as the reader / writer in communication related to the first communication path becomes the master apparatus” (when the first communication path is NFC communication) However, it is not limited to the above.

  The information processing apparatus 100A and the information processing apparatus 100D perform the role determination process as described above, so that one of the information processing apparatuses 100D and 100D performs the role of the master apparatus in the communication via the second communication path in the network after integration. It will serve as a slave device.

(C) Second state related to network integration (FIG. 3C)
When the roles of the information processing apparatus 100A and the information processing apparatus 100D in the communication via the second communication path are determined by the process (B-2), the information processing apparatus 100A and the information are determined based on the determined roles. Communication with the processing device 100D via the second communication path is started. Here, FIG. 3C illustrates a case where it is determined that the information processing apparatus 100A plays a role as a slave apparatus and the information processing apparatus 100D also plays a role as a master apparatus by the process (B-2). An example is shown. As communication via the second communication path is started between the information processing device 100A and the information processing device 100D, the information processing device 100A (slave device S6) is integrated into the network N2, as shown in FIG. 3C. A new network N3 will be formed. More specifically, the state shown in FIG. 3C is realized by the following processing (C-1) and processing (C-2).

(C-1) Network integration preparation process based on the determined role The information processing apparatus 100A that has been determined to serve as a slave apparatus by the process (B-2) described above is a slave apparatus that configures the network N1. The communication through the second communication path with the information processing apparatuses 100B and 100C is disconnected (disconnection processing).

  In addition, the information processing apparatus 100A, for example, the pass code (for example, the random number included in the payload 188 illustrated in FIG. 4) transmitted in the process (B-1) before disconnecting the communication through the second communication path. The information is transmitted to the information processing apparatuses 100B and 100C. As described above, the information processing apparatuses 100B and 100C that function as slave apparatuses in the network N1 and the information processing apparatus 100D that functions as a master apparatus in the network N2 can share the same passcode. Therefore, in the process (D-1) described later, the information processing apparatus 100D and the information processing apparatus 100B and the information processing apparatus 100D and the information processing apparatus 100C can perform authentication using the passcode. . Therefore, the integration of the network N1 and the network N2 can be realized while maintaining security.

  In the above, the information processing apparatus 100A transmits the passcode transmitted in the process (B-1) to the information processing apparatuses 100B and 100C (an example in which a common passcode is set in the network N1). However, the present invention is not limited to the above. For example, the information processing apparatus 100A can generate an individual passcode for each of the other information processing apparatuses 100 configuring the network N1 and transmit it to the corresponding information processing apparatus 100.

  Here, the information processing apparatus 100A can transmit an external connection list including passcode information to the information processing apparatus 100D by the process (B-1). Therefore, even when the information processing apparatus 100A generates individual passcodes as in the above example, the information processing apparatus 100D and the information processing apparatus 100B and the information processing apparatus 100D and the information processing apparatus 100C are respectively The same passcode can be shared. Even when the information processing apparatus 100A sets a common passcode in the network N1, the information processing apparatus 100A uses the information processing apparatus (B-1) to process the external connection list including the passcode information. Needless to say, it can be transmitted to 100D. When authentication is not performed, the information processing apparatus 100A does not include passcode information (authentication information) in the external connection list.

  By the disconnection process, each of the information processing apparatuses 100B and 100C configuring the network N1 cannot communicate with the other information processing apparatuses 100 configuring the network N1 through the second communication path. That is, the network N1 does not function as a star network by the disconnection process.

  Further, the information processing apparatus 100D determined to play the role of the master apparatus by the process (B-2) performs the second communication with the slave apparatuses (information processing apparatuses 100E, 100F, 100G) configuring the network N2. Maintain communication over the road.

(C-2) Pairing processing in the second communication path The information processing apparatus 100D serving as the master apparatus and the information processing apparatus 100A serving as the slave apparatus are paired by communication through the second communication path. Perform ring processing. Here, a pairing process is implement | achieved by performing the following process, for example by communication by a 2nd communication path. Here, communication through the second communication path between the information processing apparatus 100A and the information processing apparatus 100D is performed by a frequency hopping pattern determined by the information processing apparatus 100D that plays the role of a master device.

<Example of pairing process>
・ Public key exchange (shared key sharing)
The information processing apparatus 100 uses a public key (for example, a 192-bit elliptic code) that is packetized based on address information (for example, the BD address shown in FIG. 4) included in the received packet received by the first communication path. ) Information is transmitted to the connection destination through communication using the second communication path. The information processing apparatus 100 calculates a common key based on the public key information transmitted by the connection information processing apparatus 100 in the same manner as described above (DiffieHellman key exchange method).

Authentication processing The information processing apparatus 100 exchanges certificates with the information processing apparatus 100 that is the connection destination through the second communication path, and proves that the communication target is appropriate.

-Generation of link key The information processing apparatus 100 generates a link key, which is information used for authentication in the second and subsequent communications.

  By performing the pairing by the process (C-2), the information processing apparatus 100A and the information processing apparatus 100D are in a state in which data transmission and reception through the second communication path can be arbitrarily performed. Note that the pairing between the information processing apparatus 100A and the information processing apparatus 100D is a series of processes (B-1) and (C-2) related to communication via the first communication path. It can also be taken as. When considered as described above, the pairing by the above processing can be regarded as a pairing method corresponding to an OOB (OutOfBand) method which is one of SSP (Secure Simple Pairing) authentication methods. Needless to say, the pairing method according to the embodiment of the present invention is not limited to the method corresponding to the OOB method.

  The information processing 100A and the information processing apparatus 100D perform, for example, the process (C-1) and the process (C-2), thereby realizing the state illustrated in FIG. 3C.

(D) Integrated state (FIG. 3D)
Through the process (C), a new star network N3 in which the information processing apparatus 100A constituting the network N1 is integrated with the network N2 is formed (FIG. 3C). However, as shown in FIG. 3C, since the information processing apparatuses 100B and 100C that constitute the network N1 do not constitute the network N3, the state of FIG. 3C is a state in which the network N1 and the network N2 are integrated. There is no such thing.

  Therefore, the information processing apparatus 100D serving as a master apparatus in the network N3 performs, for example, the following process (D-1) in order to realize integration of the network N1 and the network N2.

(D-1) Connection Process Using Second Communication Channel Information processing apparatus 100D determines that each of information processing apparatuses 100B and 100C is based on the network configuration information acquired from information processing apparatus 100A in the process (B-1). On the other hand, connection is established using communication via the second communication path. More specifically, the information processing apparatus 100D is configured to perform communication using the second communication path with each of the information processing apparatuses 100B and 100C from the external connection list included in the network configuration information acquired from the information processing apparatus 100A. Retrieve information. Then, the information processing apparatus 100D performs communication through the second communication path with each of the information processing apparatuses 100B and 100C based on the extracted setting information. Here, the setting information included in the external connection list includes, for example, address information (BD address) or address information (BD address) and passcode (random number), but is not limited thereto.

  By the process (D-1), data transmission / reception through the second communication path can be arbitrarily performed between the information processing 100D and the information processing apparatus 100B and between the information processing 100D and the information processing apparatus 100C. It becomes possible. Here, the information processing apparatus 100D and the information processing apparatus 100B and the information processing apparatus 100D and the information processing apparatus 100C have the same path by the process (B-1) and the process (C-1). Sharing code. Therefore, the information processing apparatus 100D can be in a state in which data transmission / reception can be arbitrarily performed after authentication with the information processing apparatuses 100B and 100C using the passcode.

  Further, by the process of (D-1), a new star-type network N4 in which the information processing apparatuses 100B and 100C constituting the network N1 are integrated with the network N3 is formed (FIG. 3D).

  As illustrated in FIG. 3D, the network N4 corresponds to a star network in which the network N1 and the network N2 illustrated in FIG. 3A are integrated. That is, the processes shown in the processes (B-1) to (D-1) are performed between the information processing apparatus 100 configuring the first network and the information processing apparatus 100 configuring the second network. By doing so, the integration of the star network is realized.

  Therefore, by the process related to the communication stabilization approach according to the embodiment of the present invention, it is possible to further reduce the possibility of an unintended communication failure than in the case of a scatternet or the case of using a conventional technique. In addition, since the processing related to the communication stabilization approach according to the embodiment of the present invention reduces the complexity of processing related to communication compared to the case of a scatternet, for example, a game using communication via the second communication path It is easier to implement an application that uses communication via the second communication path between the information processing apparatuses.

  Therefore, between the information processing apparatuses constituting the integrated network including communication between the information processing apparatuses belonging to different star type networks by the processing related to the communication stabilization approach according to the embodiment of the present invention. Communication can be performed more stably.

[Specific example of processing related to communication stabilization approach]
Next, the process related to the communication stabilization approach according to the embodiment of the present invention described above will be described more specifically. In the following, a process in the case where the network N1 and the network N2 illustrated in FIG. 3A are integrated into one star network will be described as an example. In the following description, it is assumed that the communication other than the step clearly indicating that the communication is based on the “first communication path” is the communication based on the “second communication path”. In the following description, it is assumed that the network N1 is a “first network” and the network N2 is a “second network”, but the network N1 is a “second network” and the network N2 Needless to say, may be the “first network”.

[1] First Example of Processing Related to Communication Stabilization Approach FIG. 7 is an explanatory diagram showing a first example of processing (communication method) related to the communication stabilization approach according to the embodiment of the present invention. Here, FIG. 7 shows a case where the master device M1 (information processing device 100A) of the network N1 shown in FIG. 3A performs communication via the first communication path to the master device M2 (information processing device 100D) of the network N2. 2 shows an example of processing (processing related to a communication stabilization approach).

  8A to 8C are explanatory diagrams for supplementing an example of the processing illustrated in FIG. Hereinafter, a first example of processing related to the communication stabilization approach will be described with reference to FIGS. 8A to 8C as appropriate.

  In the first example of processing related to the communication stabilization approach described below with reference to FIG. 7, the master device of the network N1 is represented as “master device (100A)”, and the slave device of the network N1 is represented as “slave device ( 100B, 100C) ”. In the first example of the process related to the communication stabilization approach described with reference to FIG. 7, the master device of the network N2 is represented as “master device (100D)”, and the slave device of the network N1 is represented by “slave device ( 100E-100G) ".

  The master device (100A) generates an external connection list related to the first network (S100; external connection list creation process).

  9A and 9B are explanatory diagrams illustrating an example of the external connection list according to the embodiment of the present invention. Here, FIG. 9A shows an example of setting information for connecting an external device to each of the information processing devices 100B and 100C constituting the network N1 via the second communication path, and the setting information is a BD address. Is shown. FIG. 9B shows an example of a passcode used for authentication when communication is performed with each of the information processing apparatuses 100B and 100C configuring the network N1 through the second communication path.

  Since the master device (100A) is a master device in the network N1, the master device (100A) stores information for communicating with the information processing devices 100B and 100C, which are slave devices, on the communication path through the second communication path. Therefore, the master device (100A) can generate setting information as shown in FIG. 9A by using the stored information, for example. When the master device (100A) already stores setting information as shown in FIG. 9A, the master device (100A) can also include the stored setting information itself in the external connection list.

  Further, the master device (100A) generates a passcode as shown in FIG. 9B by generating a random number, for example. Here, the master device (100A) generates a passcode by generating a random number under predetermined random number generation conditions such as setting a maximum number of bits, but is not limited to the above. FIG. 9B shows an example in which the master device (100A) generates a passcode common to the information processing devices 100B and 100C, but is not limited to the above. For example, the master device (100A) can generate a unique pass code (a unique pass code for each address shown in FIG. 9A) for each slave device belonging to the network N1.

  The master device (100A) can generate, for example, the setting information shown in FIG. 9A or the external connection list including the setting information shown in FIG. 9A and the passcode shown in FIG. 9B by the processing as described above.

  With reference to FIG. 7 again, a first example of processing related to the communication stabilization approach will be described. When the external connection list generation process is performed in step S100, the master device (100A) transmits information such as the first setting information and the first network configuration information to the master device (100D) via the first communication path. (S102).

  Here, the information transmitted in step S102 corresponds to the information shown in FIG. 4, for example. The first setting information transmitted in step S102 corresponds to the setting information 182 shown in FIG. In addition, the first network configuration information transmitted in step S102 corresponds to the setting information 184 shown in FIG. 4, and the external connection list generated in step S100 is included in the first network configuration information.

  In step S102, the master device (100D) that has received the information transmitted from the master device (100A) through the first communication path generates an external connection list (S104; external connection list creation processing).

  10A and 10B are explanatory diagrams showing an example of the external connection list according to the embodiment of the present invention. Here, FIG. 10A shows an example of setting information for connecting an external device to each of the information processing devices 100E, 100F, and 100G configuring the network N2 via the second communication path, and the setting information is a BD address. Shows the case. FIG. 10B illustrates an example of a passcode used for authentication when communication is performed with each of the information processing apparatuses 100E, 100F, and 100G configuring the network N2 through the second communication path.

  Since the master device (100D) is a master device in the network N2, like the master device (100A), setting information as shown in FIG. 10A can be generated by using the stored information. When the master device (100D) already stores setting information as shown in FIG. 10A, the master device (100D) can also include the stored setting information itself in the external connection list.

  Also, the master device (100D) generates a pass code as shown in FIG. 10B by generating a random number, for example, as in the master device (100A). FIG. 10B shows an example in which the master device (100D) generates a passcode common to the information processing devices 100E, 100F, and 100G, but is not limited thereto. For example, the master device (100D) can also generate a unique pass code (a unique pass code for each address shown in FIG. 10A) for each slave device belonging to the network N2.

  The master device (100D) can generate, for example, the external connection list including the setting information illustrated in FIG. 10A or the setting information illustrated in FIG. 10A and the passcode illustrated in FIG.

  With reference to FIG. 7 again, a first example of processing related to the communication stabilization approach will be described. In step S102, the master device (100D) that has received the information transmitted from the master device (100A) through the first communication path performs a role determination process based on the received information (S106). Here, the master device (100D) determines the role in communication through the second communication path with the master device (100A), for example, by performing the process (B-2).

  More specifically, for example, the master device (100D) grasps the role desired by the own device based on the designated role information corresponding to the own device, and the designated role included in the received first network configuration information. Based on the information, the master device (100A) grasps the desired role. Then, the master device (100D) determines a role in communication through the second communication path with the master device (100A) based on the role arbitration information (for example, FIG. 6). For example, when the master device (100D) desires the role of the master and the master device (100A) desires the role of the master, the master device (100D) is more connected than the master device (100A). Because there are a lot of external devices, decide to play the role of master. Hereinafter, a case will be described as an example where the master device (100D) determines to play the role of the master in communication with the master device (100A) in the second communication path in step S106.

  FIG. 7 illustrates an example in which the master device (100D) performs the process of step S106 after the process of step S104, but is not limited thereto. For example, the master device (100D) can perform the process of step S104 and the process of step S106 independently. In the above case, the master device (100D) can perform the process of step S104 after the process of step S106, and can also perform the process of step S106 in synchronization with the start of the process of step S104. .

  When the processing of steps S104 and S106 is performed, the master device (100D) transmits information such as second setting information and second network configuration information to the master device (100A) via the first communication path (S108). ).

  Here, the information transmitted in step S108 corresponds to the information shown in FIG. 4, for example. The second setting information transmitted in step S108 corresponds to the setting information 182 shown in FIG. Further, the second network configuration information transmitted in step S108 corresponds to the setting information 184 shown in FIG. 4, and the external connection list generated in step S104 is included in the second network configuration information.

  FIG. 7 illustrates an example in which the master device (100D) performs the process of step S108 after the process of step S106, but is not limited thereto. For example, the master device (100D) can perform the process of step S106 and the process of step S108 independently. In the above case, the master device (100D) can perform the process of step S106 after the process of step S108, and can also perform the process of step S108 in synchronization with the start of the process of step S106. .

  In addition, the master device (100D) can further transmit information indicating the role determined by the master device (100D) as a result of the process in step S106 in step S108. Further, the master device (100D) may include the result of the process of step S106 (that is, the determined role information indicating the determined role) in the second network configuration information instead of the designated role information. In the above case, the master device (100A) that has received the information indicating the role determined by the master device (100D) on the first communication path is to grasp the role determined by the master device (100D) from the received information. Is possible. Therefore, the master device (100A) simplifies the role determination process in step S110, which will be described later, for example, “when the master device (100D) determines to play the role of the master, it determines to play the role of the slave”. It can also be converted. Here, simplification of the above-described role determination process means that the information processing apparatus 100 can determine a role that uses role arbitration information (for example, FIG. 6).

  In step S108, the master device (100A) that has received the information transmitted from the master device (100D) through the first communication path performs a role determination process based on the received information (S110). Here, the master device (100A) performs, for example, the second processing with the master device (100D) by performing the process (B-2) in the same manner as the process of step S106 in the master device (100D). Although the role in communication via a communication path is determined, it is not limited to the above.

  Hereinafter, a case will be described as an example where the master device (100A) has determined to play the role of a slave in communication via the second communication path with the master device (100D) by the process of step S110.

  The master device (100A) determined to play the role of a slave in step S110 transmits a temporary passcode to the slave devices (100B, 100C) of the network N1 (S112). Here, the temporary passcode transmitted by the master device (100A) in step S112 corresponds to the passcode (for example, FIG. 9B) included in the external connection list of the first network configuration information transmitted in step S102. Therefore, the master device (100D) and the slave devices (100B, 100C) share the same passcode by the process of step S112. Although FIG. 7 illustrates an example in which the passcode is a temporary passcode (for example, a temporary passcode that can be normally authenticated for a certain period), the present invention is not limited to the above.

  When the temporary passcode is transmitted in step S112, the master device (100A) disconnects the communication with the slave device (100B, 100C) through the second communication path (S114; second communication path disconnection process).

  The master device (100D) determined to play the role of the master in step S106 starts communication with the master device (100A) via the second communication path (S116; second communication path connection process). Here, in order for the master apparatus (100D) to secure the time for performing the processes of Steps S110 to S114 in the communication target master apparatus (100A), for example, after a predetermined time has elapsed after the process of Step S108 is completed, Although the process of step S116 is performed, it is not limited to the above.

  The state shown in FIG. 3A (the state before the integration of the network N1 and the network N2) is changed to the state shown in FIG. 8A by the process of step S114 in the master device (100A) and the process of step S116 in the master device (100D). And change. Here, the location indicated by the broken line in FIG. 8A represents the communication related to the processing in step S114 and the processing in step S116. The same applies to FIGS. 8B and 8C described below and FIGS. 12A to 12C, 14B, and 14C described later.

  When communication via the second communication path with the master device (100A) is started in step S116, the master device (100D) starts communication via the second communication path with the slave devices (100B, 100C). (S118; second communication path connection process).

  Here, the master device (100D) acquires setting information (for example, FIG. 9A) for communicating with the slave devices (100B, 100C) through the second communication path from the master device (100A) in step S102. Yes. Therefore, the master device (100D) can connect to the slave devices (100B, 100C) through the second communication path by using the setting information.

  Further, the master device (100D) and the slave devices (100B, 100C) store the same temporary passcode by the process of step S102 and the process of step S112. Therefore, the master device (100D) and the slave devices (100B, 100C) can start communication using the second communication path with improved security by authentication using the temporary passcode.

  By the process of step S118 by the master device (100D), the state shown in FIG. 8A changes to the state shown in FIG. 8B, that is, the state where the network N1 and the network N2 are integrated into one star network.

  FIG. 7 illustrates an example in which the master device (100D) performs the process of step S118 after the process of step S116, but is not limited thereto. For example, the master device (100D) can perform the process of step S116 and the process of step S118 independently. In the above case, the master device (100D) can perform the process of step S116 after the process of step S118, and can also perform the process of step S118 in synchronization with the start of the process of step S116. . Even in the above case, the state where the network N1 and the network N2 shown in FIG. 8B are integrated into one star network is realized.

  Therefore, the two star types are performed by performing the processing from step S100 to step S118 described above between the information processing apparatus 100 configuring the first network and the information processing apparatus 100 configuring the second network. Are integrated into a single star network.

  In addition, the master device (100D) that functions as a master device in the integrated network and any information processing device 100 that functions as a slave device in the network can arbitrarily perform communication through the second communication path. . In addition, one information processing apparatus 100 that functions as a slave apparatus in the integrated network and another information processing apparatus 100 that functions as a slave apparatus are connected via a second communication path via the master apparatus (100D). Communication can be performed arbitrarily.

  Therefore, communication by the second communication path is realized between any of the master device (100A), the slave devices (100B, 100C), the master device (100D), and the slave devices (100E to 100G). (S120). Here, the communication using the second communication path in step S120 is, for example, for executing an application using communication using the second communication path between information processing apparatuses, such as a game using communication using the second communication path. Such communication is mentioned, but not limited to the above. For example, the communication using the second communication path in step S120 may be communication related to transmission / reception of various data such as image data representing moving / still images and audio data.

  In addition, for example, when the application using the communication via the second communication path between the information processing apparatuses is terminated, it is possible to cancel the network integration. Hereinafter, an example of processing for canceling network integration will be described.

  The master device (100D) functioning as the master device in the integrated network disconnects communication through the second communication path with the master device (100A) belonging to the different network N1 (S122; second communication). Road cutting process). Further, the master device (100D) disconnects communication through the second communication path with the slave devices (100B, 100C) belonging to different networks N1 (S124; second communication path disconnection process).

  FIG. 7 illustrates an example in which the master device (100D) performs the process of step S124 after the process of step S122, but is not limited thereto. For example, the master device (100D) can perform the process of step S122 and the process of step S124 independently. In the above case, the master device (100D) can perform the process of step S122 after the process of step S124, and can also perform the process of step S124 in synchronization with the start of the process of step S122. .

  The state in which the network N1 and the network N2 shown in FIG. 8B are integrated into one star network by the processing in step S122 and the processing in step S124 by the master apparatus (100D) changes to the state shown in FIG. 8C. To do.

  Further, when the communication through the second communication path between the master device (100D) and the slave devices (100B, 100C) is disconnected by the process in step S124, the master device (100D) performs the temporary passcode in the process in step S118. The link key generated by using it is deleted (S126). Further, the slave devices (100B, 100C) whose communication with the master device (100D) through the second communication path has been disconnected are generated using the temporary passcode received from the master device (100A) in the process of step S112. The key is deleted (S128).

  Here, the link key is automatically generated by the master device (100D) and the slave devices (100B, 100C) using the temporary passcode. Therefore, for example, it may be desirable to use a link key to allow temporary connection between the master device (100D) and the slave devices (100B, 100C) from the viewpoint of improving security. That is, the process in step S126 in the master device (100D) and the process in step S128 in the slave devices (100B, 100C) shown in FIG. 7 are performed to improve security.

  For example, when a permanent connection between the master device (100D) and the slave devices (100B, 100C) is allowed by a user operation or the like, the processing in step S126 and the processing in step S128 are not performed. Also good.

  As described above, the processing shown in FIG. 7 is performed between the information processing apparatus 100 that configures the first network and the information processing apparatus 100 that configures the second network. The network can be integrated into a single star network. Therefore, the processing according to the first example of the communication stabilization approach shown in FIG. 7 can further reduce the possibility of an unintended communication failure than in the case of a scatternet or the case of using a conventional technique. . In addition, the process according to the first example of the communication stabilization approach reduces the complexity of the process related to communication as compared to the case of the scatternet. For example, a game using communication via the second communication path, etc. Realization of an application using communication via the second communication path between the information processing apparatuses becomes easier.

  Therefore, the processing according to the first example of the communication stabilization approach according to the embodiment of the present invention allows an arbitrary network constituting an integrated network including communication between information processing apparatuses belonging to different star type networks. Communication between information processing apparatuses can be performed more stably.

[2] Second Example of Processing Related to Communication Stabilization Approach In the processing related to the first example of the above communication stabilization approach, master device M1 (information processing device 100A) of network N1 shown in FIG. The example of the process in the case of performing communication via the first communication path to the master device M2 (information processing device 100D) is shown. However, the process related to the communication stabilization approach according to the embodiment of the present invention is a process when the master device of the first network performs communication using the first communication path to the master device of the second network. Not limited. Therefore, next, as processing according to the second example of the communication stabilization approach according to the embodiment of the present invention, the slave device of the first network transmits the first communication path to the master device of the second network. An example of processing when performing communication according to will be described.

  FIG. 11 is an explanatory diagram illustrating a second example of processing (communication method) related to the communication stabilization approach according to the embodiment of the present invention. Here, FIG. 11 shows a case where the slave device S1 (information processing device 100B) of the network N1 shown in FIG. 3A performs communication via the first communication path to the master device M2 (information processing device 100D) of the network N2. 2 shows an example of a part of the processing (processing related to the communication stabilization approach).

  12A to 12D are explanatory diagrams for supplementing an example of the processing illustrated in FIG. Hereinafter, a second example of processing related to the communication stabilization approach will be described with reference to FIGS. 12A to 12D as appropriate.

  In the second example of processing related to the communication stabilization approach described below with reference to FIG. 11, the master device of the network N1 is represented as “master device (100A)”, and the master device of the network N2 is represented by “master device ( 100D) ”. In the second example of the process related to the communication stabilization approach described with reference to FIG. 11, the slave device S1 of the network N1 is represented as “slave device (100B)”, and the slave device S2 of the network N1 is represented by “slave”. Device (100C) ”.

  The slave device (100B) transmits an external connection list acquisition request (acquisition request) for requesting transmission of the external connection list to the master device (100A) (S200). Here, the generation of the external connection list corresponding to the network N1 is a process that can be performed by the master device (100A) that functions as a master in the network N1, and the slave device (100B) that functions as a slave stores the external connection list. It cannot be created (directly). This is because the slave device (100B) cannot directly communicate with the slave device (100C), which is another slave device of the network N1, through the second communication path. Therefore, the slave device (100B) acquires an external connection list corresponding to the network N1 by transmitting an external connection list acquisition request for requesting transmission of the external connection list to the master device (100A) in step S200. .

  The master device (100A) that has received the external connection list acquisition request transmitted from the slave device (100B) in step S200 generates an external connection list according to the external connection list acquisition request (S202; external connection list generation processing). ).

  Here, the master device (100A) generates setting information in which the information of the information processing device 100B in the setting information illustrated in FIG. 9A is replaced with the information of the information processing device 100A, and the generated setting information is the external connection information. Include in In addition, the master device (100A) can generate a passcode as shown in FIG. 9B and further include the generated passcode in the external connection list. Hereinafter, a case where the master device (100A) generates a passcode in response to the received external connection list acquisition request and includes the generated passcode in the external connection list will be described as an example. Hereinafter, a case where the passcode generated by the master device (100A) is a temporary passcode will be described as an example. Note that the pass code in the processing according to the second example of the communication stabilization approach may be a pass code unique to the network N1, or may be a unique pass code for each information processing apparatus 100 configuring the network N1. May be.

  The master device (100A) that generated the external connection list in step S202 transmits the external connection list to the slave device (100B) (S204). In addition, the master device (100A) transmits the temporary passcode generated in step S202 to the slave device (100C) (S206).

  FIG. 11 illustrates an example in which the master device (100A) performs the process of step S206 after the process of step S204, but is not limited thereto. For example, the master device (100A) can perform the process of step S204 and the process of step S206 independently. In the above case, the master device (100A) can perform the process of step S204 after the process of step S206, and can also perform the process of step S206 in synchronization with the start of the process of step S204. .

  When the temporary passcode is transmitted to the slave device (100C) in step S206, the master device (100A) disconnects communication with the slave device (100C) through the second communication path (S206; second communication path). Cutting process).

  Then, the master device (100A) performs a role switching process for switching the role played in the network N1 with the slave device (100B) (S210). By performing the process of step S210, the slave device (100B) becomes a new master device that plays the role of the master in the network N1, and the master device (100A) becomes a new slave device that plays the role of the slave.

  Moreover, the state (initial state) of the network N1 illustrated in FIG. 12A changes to the state illustrated in FIG. 12B by the processing of steps S200 to S210 described above.

  In step S210, the slave device (100B) that newly functions as the master in the network N1 starts communication with the slave device (100C) through the second communication path (S212; second communication path). Connection process). Here, the slave device (100B) can perform the process of step S212 by using the external connection list acquired in step S204.

  By the processing in step S212, the state shown in FIG. 12B is changed to the state shown in FIG. 12C, that is, a state where a new star network N1 ′ is formed in which the information processing apparatus 100 functioning as the master is switched from the network N1. Change.

  Here, “when the information processing apparatus 100B performs communication through the first communication path to the master apparatus (100D) of the network N2 through the first communication path after forming the new network N1 ′” ( FIG. 12D) corresponds to “a case where the master device of the first network communicates with the master device of the second network through the first communication path” (FIG. 3B).

  Therefore, after performing the processing of steps S200 to S212, for example, by performing the processing according to the first example of the communication stabilization approach similar to FIG. 7, two star networks are converted into one star network. Can be integrated. In FIG. 11, processing corresponding to the processing according to the first example of the communication stabilization approach is omitted.

  As described above, in the processing according to the second example of the communication stabilization approach according to the embodiment of the present invention, the slave device of the first network is switched to a new master device. In the process according to the second example of the communication stabilization approach, the new master device switched in the first network communicates with the master device in the second network through the first communication path. That is, in the processing according to the second example of the communication stabilization approach, the communication stabilization approach is performed between the information processing apparatus 100 configuring the first network and the information processing apparatus 100 configuring the second network. Processing similar to the processing according to the first example is performed. Therefore, the processing according to the second example of the communication stabilization approach is similar to the processing according to the first example of the communication stabilization approach, and communication that is not intended compared to the case of using the scatternet or the conventional technique. The possibility of occurrence of a failure can be further reduced. Further, the processing according to the second example of the communication stabilization approach reduces the complexity of the processing related to communication compared to the case of the scatternet. Realization of the used application becomes easier.

  Therefore, by the processing according to the second example of the communication stabilization approach according to the embodiment of the present invention, an arbitrary network constituting an integrated network including communication between information processing apparatuses belonging to different star networks Communication between information processing apparatuses can be performed more stably.

[3] Third Example of Processing Related to Communication Stabilization Approach In the first and second examples of processing related to the above communication stabilization approach, the master device in the first network (the master device after roll switching is Shows an example of processing in the case of performing communication through the first communication path to the master device in the second network. However, the process related to the communication stabilization approach according to the embodiment of the present invention is a process when the master device of the first network performs communication using the first communication path to the master device of the second network. Not limited. Therefore, next, as processing according to the third example of the communication stabilization approach according to the embodiment of the present invention, the master device of the first network transmits the first communication path to the slave device of the second network. An example of processing when performing communication according to will be described.

  FIG. 13 is an explanatory diagram illustrating a third example of processing (communication method) related to the communication stabilization approach according to the embodiment of the present invention. Here, FIG. 13 shows a case where the master device M1 (information processing device 100A) of the network N1 shown in FIG. 3A performs communication via the first communication path to the slave device S3 (information processing device 100E) of the network N2. 2 shows an example of processing (processing related to a communication stabilization approach).

  14A to 14C are explanatory diagrams for supplementing an example of the processing illustrated in FIG. Hereinafter, a third example of processing related to the communication stabilization approach will be described with reference to FIGS. 14A to 14C as appropriate.

  In the third example of the process related to the communication stabilization approach described below with reference to FIG. 13, the master device of the network N1 is represented as “master device (100A)”, and the slave device of the network N1 is represented as “slave device ( 100B, 100C) ”. In the third example of the process related to the communication stabilization approach described with reference to FIG. 13, the master device of the network N2 is represented as “master device (100D)”. In the third example of the process related to the communication stabilization approach described with reference to FIG. 13, the slave device S3 of the network N2 is represented as “slave device (100E)”, and the slave devices S4 and S5 of the network N2 are represented. This is expressed as “slave device (100F, 100G)”.

  The master device (100A) generates an external connection list related to the first network, similarly to step S100 of FIG. 7 (S300; external connection list creation process).

  When the external connection list generation process is performed in step S300, the master device (100A) transmits information such as the first setting information and the first network configuration information on the first communication path, as in step S102 of FIG. The data is transmitted to the slave device (100E) (S302, FIG. 14A).

  In step S302, the slave device (100E) that has received the information transmitted from the master device (100A) on the first communication path sends an external connection list acquisition request to the master device (100D), as in step S200 of FIG. (S304).

  The master device (100D) that has received the external connection list acquisition request transmitted from the slave device (100E) in step S304 generates an external connection list corresponding to the external connection list acquisition request (S306; external connection list generation processing). ).

  15A and 15B are explanatory diagrams illustrating an example of the external connection list according to the embodiment of the present invention. Here, FIG. 15A shows an example of setting information for connecting an external device to each of the information processing devices 100D, 100F, and 100G configuring the network N2 via the second communication path, and the setting information is a BD address. Shows the case. FIG. 15B illustrates an example of a passcode used for authentication when communication is performed with each of the information processing apparatuses 100D, 100F, and 100G configuring the network N2 through the second communication path. FIG. 15B shows an example in which the master device (100D) generates a passcode common to the information processing devices 100D, 100F, and 100G, but is not limited thereto. For example, the master device (100D) can generate a unique passcode for each address shown in FIG. 15A. Hereinafter, a case where the pass code generated by the master device (100D) is a temporary pass code will be described as an example.

  Here, as shown in FIG. 15A, the master device (100D) is an information processing device 100 that configures a network N2 other than the slave device (100E) from which the external device has received the first setting information and the first network configuration information. An external connection list including setting information for performing communication with is generated.

  The master device (100D) that generated the external connection list in step S304 transmits the external connection list to the slave device (100E) (S308).

  The slave device (100E) that has received the external connection list transmitted from the master device (100D) in step S308 performs a role determination process as in step S106 of FIG. 7 (S310). Hereinafter, a case will be described as an example where it is determined in step S310 that the slave device (100E) plays the role of a slave in communication via the second communication path with the master device (100A).

  FIG. 13 illustrates an example in which the slave device (100E) performs the process of step S310 after the process of step S304, but is not limited thereto. For example, the slave device (100E) can perform the process of step S304 and the process of step S310 independently. In the above case, the slave device (100E) can perform the process of step S304 after the process of step S310, and can also perform the process of step S310 in synchronization with the start of the process of step S304. .

  In addition, the slave device (100E) that has received the external connection list transmitted from the master device (100D) in step S308 masters information such as the third setting information and the second network configuration information on the first communication path. The data is transmitted to the device (100A) (S312).

  Here, the information transmitted in step S312 corresponds to the information shown in FIG. 4, for example. The third setting information transmitted in step S312 corresponds to the setting information 182 shown in FIG. Further, the second network configuration information transmitted in step S312 corresponds to the setting information 184 shown in FIG. 4, and the second network configuration information includes the external connection list transmitted from the master device (100D) in step S308. Will be included.

  In step S314, the master device (100A) that has received the information transmitted from the slave device (100E) through the first communication path performs a role determination process based on the received information, similarly to step S110 in FIG. (S314). Hereinafter, a case where the master device (100A) determines in step S314 to play the role of the master in the communication via the second communication path with each information processing device 100 of the network N2 will be described as an example. .

  The master device (100D) having transmitted the external connection list in step S308 transmits the temporary passcode generated in step S306 to the slave devices (100F, 100G) (S316). Then, the master device (100D) disconnects communication with the slave devices (100F, 100G) via the second communication path (S318; second communication path disconnection process). Further, the master device (100D) disconnects communication with the slave device (100E) through the second communication path (S320; second communication path disconnection process). Note that the order in which the master device (100D) performs the processes in steps S318 and S320 is not limited to the example illustrated in FIG.

  The state shown in FIG. 14A changes to the state shown in FIG. 14B by the processing in steps S318 and S320 in the master device (100D).

  The master device (100A) determined to play the role of the master in step S314 communicates with the slave device (100E), the master device (100D), and the slave devices (100F, 100G) via the second communication path. Is started (S322 to S326; second communication path connection processing). Here, the master device (100A) causes the master device (100D) of the network N2 to secure time for performing the processing of steps S316 to S320, for example, after a predetermined time elapses after the processing of step S314 is completed. Although the process of step S322-S326 is performed, it is not restricted above. Note that the order in which the master device (100A) performs the processes of steps S322 to S326 is not limited to the example illustrated in FIG.

  Due to the processing of steps S322 to S326 by the master apparatus (100A), the state shown in FIG. 14B changes to the state shown in FIG. 14C, that is, the state where the network N1 and the network N2 are integrated into one star network. To do.

  Therefore, two star types are obtained by performing the processing from step S300 to step S326 described above between the information processing apparatus 100 configuring the first network and the information processing apparatus 100 configuring the second network. Are integrated into a single star network.

  Therefore, the second communication path between any of the master device (100A), slave device (100B, 100C), master device (100D), slave device (100E), and slave device (100F, 100G) Communication is realized (S328).

  As described above, each of the processes shown in FIG. 13 is performed between the information processing apparatus 100 that configures the first network and the information processing apparatus 100 that configures the second network. The network can be integrated into a single star network. Therefore, the process according to the third example of the communication stabilization approach shown in FIG. 13 is more similar to the process according to the first example of the communication stabilization approach than the case of using the scatternet or the conventional technique. In addition, it is possible to further reduce the possibility of an unintended communication failure. In addition, since the processing related to the third example of the communication stabilization approach reduces the complexity of processing related to communication compared to the case of a scatternet, for example, a game using communication using the second communication path, etc. Realization of an application using communication via the second communication path between the information processing apparatuses becomes easier.

  Therefore, by the process according to the third example of the communication stabilization approach according to the embodiment of the present invention, an arbitrary network constituting an integrated network including communication between information processing apparatuses belonging to different star networks Communication between information processing apparatuses can be performed more stably.

[4] Fourth Example of Processing Related to Communication Stabilization Approach In a third example of processing related to the above communication stabilization approach, a slave device of the second network is connected to a master device of the first network. For example, the network configuration information 184 including the external connection list illustrated in FIG. 4 is transmitted by communication using one communication path. However, the information transmitted by the slave device of the second network to the master device of the first network by communication through the first communication path is not limited to the information including the network configuration information 184 shown in FIG. Therefore, next, as processing according to the fourth example of the communication stabilization approach according to the embodiment of the present invention, the master device of the first network transmits the first communication path to the slave device of the second network. Another example of processing when performing communication according to will be described.

  FIG. 16 is an explanatory diagram illustrating a fourth example of processing (communication method) related to the communication stabilization approach according to the embodiment of the present invention. Here, in FIG. 16, similarly to FIG. 13, the master device M1 (information processing device 100A) of the network N1 shown in FIG. 3A performs the first communication with the slave device S3 (information processing device 100E) of the network N2. An example of processing (processing related to a communication stabilization approach) in the case of performing communication via a path is illustrated.

  In the fourth example of the process related to the communication stabilization approach described below with reference to FIG. 16, the master device of the network N1 is represented as “master device (100A)”, and the slave device of the network N1 is represented by “slave device ( 100B, 100C) ”. In the fourth example of the process related to the communication stabilization approach described with reference to FIG. 16, the master device of the network N2 is represented as “master device (100D)”. In the fourth example of the process related to the communication stabilization approach described with reference to FIG. 16, the slave device S3 of the network N2 is represented as “slave device (100E)”, and the slave devices S4 and S5 of the network N2 are represented. This is expressed as “slave device (100F, 100G)”.

  The master device (100A) generates an external connection list related to the first network, similarly to step S100 of FIG. 7 (S400; external connection list creation process).

  When the external connection list generation process is performed in step S400, the master device (100A) transmits information such as the first setting information and the first network configuration information on the first communication path, as in step S102 of FIG. The data is transmitted to the slave device (100E) (S402).

  In step S402, the slave device (100E) that has received the information transmitted from the master device (100A) through the first communication path performs a role determination process in the same manner as in step S106 of FIG. 7 (S404). Hereinafter, a case will be described as an example where the slave device (100E) determines to play the role of the slave in the communication via the second communication path with the master device (100A) in step S404.

  In addition, when the processing in step S404 is performed, the slave device (100E) transmits information such as third setting information and third network configuration information to the master device (100A) via the first communication path (S406). ).

  Here, the information transmitted in step S406 corresponds to the information shown in FIG. 5, for example. The third setting information transmitted in step S406 corresponds to the setting information 182 shown in FIG. Also, the third network configuration information transmitted in step S406 corresponds to the setting information 194 shown in FIG. That is, the third network configuration information transmitted in step S406 does not include the external connection list corresponding to the network N2, but instead indicates that the external connection list shown in the payload 196 in FIG. 5 is transmitted later. The following list flag is included.

  In step S406, the master device (100A) that has received the information transmitted from the slave device (100E) through the first communication path performs a role determination process based on the received information, similarly to step S110 in FIG. (S408). Hereinafter, an example will be described in which the master device (100A) determines in step S408 to play the role of the master in the communication via the second communication path with each information processing device 100 of the network N2. .

  When information is transmitted to the master device (100A) by communication through the first communication path in step S406, the slave device (100E) issues an external connection list acquisition request to the master device (100D) as in step S200 of FIG. (S410).

  The master device (100D) that has received the external connection list acquisition request transmitted from the slave device (100E) in step S410 generates an external connection list in response to the external connection list acquisition request, as in step S306 of FIG. (S412; external connection list generation process). Hereinafter, a case where the pass code generated by the master device (100D) in step S412 is a temporary pass code will be described as an example.

  The master device (100D) that generated the external connection list in step S412 transmits the external connection list to the slave device (100E) (S414).

  The master device (100D) having transmitted the external connection list in step S414 transmits the temporary passcode generated in step S412 to the slave devices (100F, 100G) (S416). Then, the master device (100D) disconnects communication with the slave devices (100F, 100G) via the second communication path (S418; second communication path disconnection process). Further, the master device (100D) disconnects communication with the slave device (100E) through the second communication path (S418; second communication path disconnection process). Note that the order in which the master device (100D) performs the processes in steps S418 and S420 is not limited to the example illustrated in FIG.

  The master device (100A) determined to play the role of the master in step S408 starts communication with the slave device (100E) via the second communication path (S422; second communication path connection processing). Here, the master device (100A) causes the master device (100D) of the network N2 to secure time for performing the processes of steps S412 to S420, for example, after a predetermined time has elapsed after the process of step S408 is completed, Although the process of step S422 is performed, it is not limited to the above.

  By the process in step S422, the master device (100A) and the slave device (100E) can communicate with each other through the second communication path. In the above state, the slave device (100E) transmits the external connection list acquired from the master device (100D) in step S414 to the master device (100A) (S424).

  Further, the master device (100A) starts communication with the master device (100D) and the slave devices (100F, 100G) via the second communication path (S426, S428; second communication path connection processing). ). Here, the master device (100A) can perform the processes of steps S426 and S428 by using the external connection list transmitted from the slave device (100E) in step S424. Note that the order in which the master device (100A) performs the processes of steps S426 and S428 is not limited to the example illustrated in FIG.

  By the processing of steps S422, S426, and S428 by the master device (100A), the master device (100A) of the network N1 and each information processing device 100 of the network N2 are connected through the second communication path. That is, the network N1 and the network N2 are integrated into one star network as shown in FIG. 14C.

  Therefore, two star types are performed by performing the processing from step S400 to step S428 described above between the information processing apparatus 100 configuring the first network and the information processing apparatus 100 configuring the second network. Are integrated into a single star network.

  Therefore, the second communication path between any of the master device (100A), slave device (100B, 100C), master device (100D), slave device (100E), and slave device (100F, 100G) Communication is realized (S430).

  As described above, each process shown in FIG. 16 is performed between the information processing apparatus 100 that configures the first network and the information processing apparatus 100 that configures the second network. The network can be integrated into a single star network. Therefore, the process according to the fourth example of the communication stabilization approach shown in FIG. 16 is more similar to the process according to the first example of the communication stabilization approach than the case of the scatternet or the case of using the conventional technique. In addition, it is possible to further reduce the possibility of an unintended communication failure. In addition, the process according to the fourth example of the communication stabilization approach reduces the complexity of the process related to communication as compared to the case of the scatternet. For example, a game using communication via the second communication path, etc. Realization of an application using communication via the second communication path between the information processing apparatuses becomes easier.

  Therefore, by the processing according to the fourth example of the communication stabilization approach according to the embodiment of the present invention, an arbitrary network constituting an integrated network including communication between information processing apparatuses belonging to different star networks Communication between information processing apparatuses can be performed more stably.

In the third and fourth examples of processing related to the communication stabilization approach, the master device in the first network communicates with the slave device in the second network through the first communication path. An example of processing in the case is shown. However, the processing related to the communication stabilization approach according to the embodiment of the present invention is not limited to the first to fourth examples. Therefore, next, as processing according to the fifth example of the communication stabilization approach according to the embodiment of the present invention, the slave device of the first network transmits the first communication path to the slave device of the second network. An example of processing when performing communication according to will be described.

  17A to 17C are explanatory diagrams illustrating a fifth example of processing (communication method) according to the communication stabilization approach according to the embodiment of the present invention.

A role switching process is performed so as to function as More specifically, in the network N1, for example, processing according to the second example of the communication stabilization approach illustrated in FIG. 11 is performed. For example, when the processing according to the second example of the communication stabilization approach illustrated in FIG. 11 is performed in the network N1, as illustrated in FIG. 17B, the information processing apparatus 100B is changed to a network N1 ′ that functions as a master.

  Here, the state illustrated in FIG. 17B corresponds to a state in which the master device in the first network communicates with the slave device in the second network through the first communication path. Therefore, the processing according to the third example (or the fourth example) of the communication stabilization approach is performed between the information processing device 100 configuring the network N1 ′ and the information processing device 100 configuring the network N2. Thus, the state shown in FIG. 17C can be realized.

  As described above, when the slave device of the first network performs communication using the first communication path to the slave device of the second network, the processing according to the second example and the third device are performed. A process combining the process according to the example (or the fourth example) is performed. As described above, as shown in FIGS. 17A to 17C, two star networks can be integrated into one star network. Therefore, the processing according to the fifth example of the communication stabilization approach is similar to the processing according to the first example of the communication stabilization approach, and communication that is not intended compared to the case of using the scatternet or the conventional technique. The possibility of occurrence of a failure can be further reduced. In addition, the processing according to the fifth example of the communication stabilization approach reduces the complexity of the processing related to communication compared to the case of the scatternet, so that, for example, a game using communication via the second communication path, etc. Realization of an application using communication via the second communication path between the information processing apparatuses becomes easier.

  For example, when the role control unit 122 determines to play the role of the master in the communication using the second communication path, the communication using the second communication path with the external device is actively performed. Therefore, in the above case, the information processing apparatus 100 functions as a master apparatus in a star network formed by the second communication path. More specifically, the communication control unit 120, based on the setting information received by the first communication path, the external device corresponding to the setting information (other information that transmitted the information through the first communication path) Communication with the processing apparatus 100) through the second communication path is actively performed.

The role control unit 122 performs, for example, the above-described process (B-2) (role determination process) and the role switching process illustrated in FIG. 11, and determines the role that the information processing apparatus 100 plays in communication through the second communication path. However, it is not limited to the above. For example, the role control unit 122 can also determine a role to play in communication through the second communication path based on an operation signal according to a user operation transmitted from the operation unit 110.

  Further, the role control unit 122 causes the information generation unit 124 to generate designated role information (for example, the BT role information in FIG. 4) by, for example, transmitting the determined role to the information generation unit 124. Note that the role control unit 122 is not limited to causing the information generation unit 124 to generate the designated role information. For example, every time a role is determined (or changed), the role control unit 122 plays a role in communication using the second communication path. It is also possible to cause the information generation unit 124 to generate role information (not shown). When the role control unit 122 causes the information generation unit 124 to generate the role information, for example, the communication control unit 120 can perform control based on the role information.

  For example, the information generation unit 124 generates information corresponding to the information generation command based on the information generation command from the communication control unit 120, the role control unit 122, or the like. Examples of information generated by the information generation unit 124 include setting information corresponding to the information processing apparatus 100, network configuration information corresponding to the network to which the information processing apparatus 100 belongs, designated role information, and the like. Not limited.

The control unit 108 includes, for example, the communication control unit 120, the role control unit 122, and the information generation unit 124, thereby leading the role of performing processing related to the communication stabilization approach according to the above-described embodiment of the present invention.
