Description

  The present invention relates to a communication technique, and more particularly to a technique for realizing wireless communication between a master and a slave.

  In general, a game machine and a controller for a game machine operated by a user are connected by a cable. Recently, however, a system for wirelessly connecting a game machine and a controller has been proposed. By adopting the wireless controller, the user can enjoy the game in a free posture.

  In the proposed system, it is assumed that the game machine and the wireless controller make a one-to-one wireless connection and the connection partner is uniquely determined. Therefore, when a plurality of users use a wireless controller, it is necessary to attach a dedicated transceiver assigned to each wireless controller to the game machine. Therefore, the user must always prepare a wireless controller and a transceiver for attaching to the game machine as a set, and the use of the wireless controller is troublesome.

  An object of the present invention is to provide a communication technique for realizing a wireless connection between a master and one or more slaves.

  One embodiment of the present invention relates to a communication apparatus capable of wireless connection with a plurality of slaves. This communication apparatus registers identification information of a slave that does not satisfy a predetermined condition, and does not establish a connection with a slave having the registered identification information at the time of wireless connection. A slave that does not satisfy a predetermined condition means a slave that does not support a communication device that functions as a master. For example, when the data format to be used is not regular, that is, when the data format condition is not satisfied, the slave is treated as a slave that does not satisfy the predetermined condition. By eliminating the connection establishment with such a slave, it becomes possible to establish a connection only with an appropriate slave, and it is possible to shorten the time required for connection establishment.

  Another aspect of the present invention relates to a game machine that can be wirelessly connected to a controller for a plurality of game machines.

A connection setting unit for establishing a connection with a controller other than the terminal device having the identification information.

  Still another aspect of the present invention provides a communication apparatus that, after wirelessly connecting with a slave, registers slave identification information and then calls the slave using the registered identification information and does not make an inquiry for connection. To do. According to this communication apparatus, after registering the identification information of the slave, since the inquiry for connection is omitted, it is possible to shorten the time required for establishing the connection.

  Still another embodiment of the present invention relates to a game machine that can be wirelessly connected to a controller for a plurality of game machines. The game machine includes a first receiving unit that receives controller identification information, a control unit that registers the received identification information in a storage unit, and a calling unit that calls the controller based on the identification information. An inquiry unit that makes a connection inquiry to the periphery of the game machine before establishing a connection is further provided, and the first reception unit receives the identification information transmitted in response to the connection inquiry by a controller located in the vicinity, and the control unit However, if it is registered in the storage unit, the inquiry unit may not perform the connection inquiry at the time of the next connection establishment. In addition, when the first reception unit receives the identification information transmitted in response to the connection inquiry by the controller located in the vicinity, and the control unit registers it in the storage unit, the inquiry unit is in charge of the next connection establishment. The connection inquiry may be performed only for a predetermined time, and the connection inquiry may be stopped when the predetermined time is exceeded.

  Still another aspect of the present invention provides a communication method in which, in a wireless connection with a slave, once the identification information of the slave is registered, the slave is called using the registered identification information and no inquiry is made for connection To do.

  Still another aspect of the present invention provides a function of registering slave identification information in a wireless connection with a slave to a master computer, and once registering the slave identification information, the registered identification information is used. A program for calling a slave and executing a function that does not perform an inquiry for connection is provided.

  ADVANTAGE OF THE INVENTION According to this invention, the communication technique which can shorten a connection establishment time can be provided.

  FIG. 1 shows an overall configuration of a game system 1 according to an embodiment of the present invention. The game system 1 according to the present embodiment includes wireless controllers 10a and 10b (hereinafter, collectively referred to as “wireless controller 10”) that perform wireless communication with the game machine 20 as an input interface by the user. . The game machine 20 has a wireless communication function. The output device 30 is configured to include a display 32 and a speaker 34, receives AV (Audio Visual) data of the game from the game machine 20 via the network 40, displays a game image on the display 32, and outputs sound from the speaker 34. Output.

  The game machine 20 and the output device 30 may be connected by wire or may be connected wirelessly. The network 40 connecting the game machine 20 and the output device 30 may take the form of a home network constructed by, for example, a network (LAN) cable or a wireless LAN. When the game machine 20 and the output device 30 are wirelessly connected, the game machine 20 and the output device 30 can be installed relatively freely as compared with the case where the game machine 20 and the output device 30 are wired with a cable or the like. You can enjoy the game at

  The wireless controller 10 and the game machine 20 may establish a wireless connection using Bluetooth (registered trademark). The game machine 20 enables wireless connection with a plurality of wireless controllers 10, that is, in the game system 1, a 1-to-N connection between the game machine 20 and the wireless controller 10 can be realized. Note that the game machine 20 functions as a master, that is, a master, and the wireless controller 10 functions as a slave. Thereby, a plurality of wireless controllers 10 can be used simultaneously without attaching a dedicated transceiver to the wireless controller 10 to the game machine 20. Hereinafter, a case where Bluetooth is adopted as a wireless communication protocol and the wireless controller 10 is a Bluetooth terminal will be taken as an example.

  FIG. 2 shows a Bluetooth state transition diagram. As shown in the figure, the state of the Bluetooth terminal can be divided into a standby phase, a synchronization establishment phase, a communication connection phase, and a low power consumption mode.

  When the wireless controller 10 is turned on immediately or when the communication link is disconnected, the wireless controller 10 enters a “standby” state. In the “standby” state, data transmission / reception is not performed.

  In the synchronization establishment phase, the game machine 20 makes a connection inquiry, that is, “inquiry” to the terminal device including the peripheral wireless controller 10, and the game machine 20 recognizes the wireless controller 10 and performs “calling”. There is a state. In the “inquiry” state, the game machine 20 broadcasts an IQ (inquiry) packet to nearby terminal devices. The wireless controller 10 that has received the IQ packet returns an FHS (Frequency Hop Synchronization) packet including the Bluetooth address and clock information to the game machine 20. In the transmission / reception at this time, since the consent regarding the frequency hopping pattern has not been established between the game machine 20 and the wireless controller 10, a fixed hopping pattern defined exclusively for inquiry is used.

  FIG. 3 shows the FHS packet structure. In the packet, LAP (Lower Address Part), UAP (Upper Address Part), and NAP (Non-significant Address Part) constitute Bluetooth_ADDR which is an address unique to the Bluetooth terminal.

  FIG. 4 shows the configuration of the Bluetooth address (Bluetooth_ADDR). A state in which the Bluetooth address is composed of a total of 48 bits is indicated by a 24-bit LAP, an 8-bit UAP, and a 16-bit NAP.

  Returning to FIG. 2, in the “calling” state, the game machine 20 receives the FHS packet from the wireless controller 10, grasps what kind of wireless controller 10 exists, and then transmits an ID packet to a specific wireless controller 10. Send. When a response to the ID packet is returned from the specific wireless controller 10, the game machine 20 transmits an FHS packet to the wireless controller 10 and notifies the wireless controller 10 of its own address and clock. Thereby, the game machine 20 and the wireless controller 10 can share the same hopping pattern.

  When “calling” is performed, a piconet is formed between the wireless controller 10 and the game machine 20 and enters a “connected” state. A piconet means a network that is temporarily formed between terminals when the Bluetooth terminals are brought close to each other, and a maximum of eight Bluetooth terminals can participate in one piconet. In one piconet, the game machine 20 functions as a parent machine and can be connected to a maximum of seven wireless controllers 10. In the “connected” state, a control packet for setting a communication link is transmitted and received, thereby enabling “data transfer”. When the data transfer is completed and the communication link is disconnected, the wireless controller 10 returns to the standby state.

  The wireless controller 10 that is a slave can shift from the connected state to three types of low power consumption modes of “park mode”, “hold mode”, and “sniff mode”. In addition, the master game machine 20 can shift from the connected state to the “hold mode”.

  The “park mode” wireless controller 10 maintains synchronization with the piconet, that is, synchronization with the hopping pattern and the master clock. However, it is not possible to exchange packets with the game machine 20. The wireless controller 10 in this state receives data from the game machine 20 at a constant time interval (beacon cycle), and can immediately join the piconet if necessary. In the park mode, the slave identifier assigned from the game machine 20, that is, the 3-bit address (1-7) given to the connected wireless controller 10 is once returned to the game machine 20. Therefore, even if the wireless controller 10 desires to rejoin the piconet, it cannot join immediately if there is no free slave identifier. Conversely, the game machine 20 gives an 8-bit park slave identifier to the wireless controller 10 that enters the park mode. The game machine 20 can manage up to 255 terminal devices in the park, and only the necessary wireless controller 10 can participate in the piconet at any time.

  The wireless controller 10 and the game machine 20 in the “hold mode” do not transmit / receive during the set fixed time (hold time) while being synchronized with the piconet, and resume communication after the hold time.

  The wireless controller 10 in the “sniff mode” performs transmission and reception at regular time intervals (sniff intervals), and can suppress power consumption during other times.

  In the present embodiment, when the wireless controller 10 that has entered the standby state communicates again after the communication is once completed, it is possible to skip the inquiry and transition to the calling state. The meeting is performed when the game machine 20 does not know what kind of terminal device exists around it, and a broadcast is issued from the game machine 20 to all slaves, and each terminal device answers it. In the calling state, since the game machine 20 already knows the presence of the wireless controller 10, the game machine 20 talks to each slave one-to-one to establish intra-piconet synchronization. Once synchronization within the piconet is established, it is not necessary to execute broadcast when communication is resumed, even if communication is completed and wireless controller 10 is in a standby state. When broadcast is executed, for example, it may take 10 seconds or more, so in this embodiment, the inquiry is omitted and the time required for establishing a connection is shortened. “Establishing intra-piconet synchronization” means that the Bluetooth address and clock information are exchanged between the game machine 20 and the wireless controller 10 to synchronize the hopping pattern.

  Further, in the present embodiment, when the game machine 20 establishes a connection, it makes a connection inquiry, that is, an inquiry to the periphery, and the identification information transmitted in response to the peripheral terminal device is recorded. The terminal device identification information is used at the next and subsequent connection establishments in order to shorten the time required for connection establishment.

  FIG. 5 shows a configuration of the game machine 20 according to the present embodiment. The game machine 20 includes a receiving unit 100, a control unit 110, a list storage unit 112, a connection setting unit 114, an inquiry unit 116, a calling unit 118, a transmission unit 120, a media drive 130, a reading unit 132, a data storage unit 134, and a processing unit. 136, a graphics engine 138, and a DA converter 140. The receiving unit 100 includes a response receiving unit 102, a deletion instruction receiving unit 104, and an operation instruction receiving unit 106. Each function of the game machine 20 is realized by a CPU, a memory, a program loaded in the memory, and the like, but here, functional blocks realized by their cooperation are depicted. The program may be built in the game machine 20 or supplied from the outside in a form stored in a recording medium. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  A medium 50 in which game data is recorded is inserted into the media drive 130. The medium 50 is, for example, a CD-ROM or DVD, and records game data such as AV data of game scenes and game programs. The game program recorded on the medium 50 may be executed directly by the processing unit 136 or may be executed by the processing unit 136 by decoding. The media drive 130 drives the medium 50, and the reading unit 132 reads game data recorded on the medium 50 into the data storage unit 134. The processing unit 136 executes the read game data.

  When the wireless connection is established between the game machine 20 and the wireless controller 10, the operation instruction receiving unit 106 receives a game operation instruction from the wireless controller 10 and sends it to the processing unit 136. The processing unit 136 processes the game data based on an operation instruction from the user, and the graphics engine 138 generates AV data of the game based on the game data processed by the processing unit 136. The AV data of the game is generated as digital data, and the DA converter 140 converts it into an analog signal and supplies it to the output device 30. As a result, video and audio reflecting the user's game operation are output from the display 32 and the speaker 34.

  The above is based on the premise that a wireless connection has been established between the game machine 20 and the wireless controller 10, but an embodiment for establishing a wireless connection will be described below.

<Example 1>
In the first embodiment, connection with a terminal device that does not support the game machine 20 is efficiently avoided, and the time required for establishing a connection with the wireless controller 10 is shortened. In a Bluetooth usage environment, even a terminal device that is not compatible with the game machine 20 can respond to an inquiry from the game machine 20 if it is compatible with Bluetooth. Therefore, in the first embodiment, the connection establishment is controlled so that the game machine 20 is not connected to, for example, the wireless controller 10 that is not permitted to be used. By avoiding connection with the non-compliant wireless controller 10, use of impersonation equipment supplied from an unauthorized manufacturer or the like is prevented.

  First, the game machine 20 can filter different types of terminal devices using the device class (Class of Device) of the FHS packet shown in FIG. Class of Device is a field indicating the type of terminal.

  FIG. 6 shows an example of a device class (Class of Device). Using this field, the game machine 20 can filter the function group. When the field takes a value other than the predetermined value, the game machine 20 recognizes that the terminal device that has returned the FHS packet is not a wireless controller.

  Returning to FIG. 5, when the inquiry unit 116 makes an inquiry to peripheral terminal devices, the response receiving unit 102 receives the FHS packet returned from the terminal device, and the control unit 110 receives the Class of the FHS packet. Analyze Device. When recognizing that the terminal device that has returned the FHS packet is not the wireless controller 10, the control unit 110 records the identification information of the terminal device in the list storage unit 112. The recorded identification information is used as a so-called black list, and the calling unit 118 of the game machine 20 does not call a terminal device registered in the black list.

  Returning to FIG. 2, in the connected state, data packets are not transmitted / received, but are transmitted / received to control packets for setting communication links, security-related control packets, low-power consumption mode-related control packets, and the like. Limited. In the connected state, an application for performing authentication between the game machine 20 and the wireless controller 10 can be executed. The response reception unit 102 may receive a response from a peripheral device, and the control unit 110 may record the identification information of the device that has failed in the list storage unit 112 as a black list.

  After transmitting / receiving the control packet in the connected state, the mode shifts to the data transfer mode. In the data transfer mode, the data format is set to be unique to the game machine 20, and data is transmitted and received in this format.

  When the slave returns an unexpected ACK in the data transfer mode, the game machine 20 determines that the slave is not a connection target device, registers the identification information owned by the device in the blacklist, and the device. The connection with is disconnected. Specifically, the response receiving unit 102 receives an ACK from the slave, and the control unit 110 determines whether or not the ACK conforms to a predetermined data format, and if not, identifies the terminal device. Information, here, an address is recorded in the list storage unit 112. This determination is made by an upper application layer. The control unit 110 records addresses of all devices that are not connection target devices as a list, and the connection setting unit 114 disconnects the connection with the device.

  FIG. 7 shows a list of non-connection target devices recorded in the list storage unit 112. The list is generated by associating a 48-bit Bluetooth address (Bluetooth_ADDR) with a device class. In this list, the address of the non-regular wireless controller whose class device is indicated by 0X080588 is recorded, but in reality, it is similarly listed for different types of terminal devices around the game machine 20.

  When the game machine 20 is turned on again and the connection with the wireless controller 10 is established, the slave is filtered by referring to the information obtained from the slave by the inquiry and the black list recorded in the list storage unit 112. It becomes possible to do. That is, when the power is turned on again, the inquiry unit 116 inquires to the peripheral terminal device via the transmission unit 120, and the response reception unit 102 receives the FHS packet from the peripheral terminal device. The connection setting unit 114 refers to the terminal device identification information included in the FHS packet and the list of non-connection target devices recorded in the list storage unit 112 to determine whether or not connection is possible. If the terminal device that has returned the FHS packet is not a connection target device, the calling unit 118 does not call the terminal device. That is, the calling unit 118 calls the wireless controller 10 other than the terminal device having the identification information registered in the list storage unit 112 based on the information obtained from the peripheral terminal device by the inquiry. By referring to the blacklist, it is not necessary to perform data analysis processing in the upper application layer each time, and incompatible terminal devices can be easily excluded from the call candidates, thereby shortening the time required to establish a connection. be able to. This also makes it possible to reduce power consumption. The connection setting unit 114 establishes a connection with the wireless controller 10 other than the terminal device having the identification information registered in the list storage unit 112.

  It should be noted that priorities may be set for unconnected devices that are hit each time an inquiry is made. Specifically, it may be determined whether a terminal device registered in the black list is a device that is accidentally registered in the black list or a device that is resident in the environment. Thereby, a non-connection target device having a low hit rate can be deleted from the list, and the data amount of the list can be reduced. Therefore, it is possible to reduce the reference time of the list and further reduce the time required for establishing a connection. Note that the user can issue a registration deletion instruction for the terminal device registered in the list storage unit 112. The registration deletion instruction is received by the deletion instruction receiving unit 104, and the control unit 110 deletes the corresponding identification information from the list storage unit 112 based on the registration deletion instruction. As a result, as described above, the data amount of the list can be reduced, and the list reference time can be shortened.

  In the above example, the game machine 20 performs filtering of the terminal device using the device class, but the terminal device may be filtered using the Bluetooth address shown in FIG. At this time, the game machine 20 may perform filtering of the terminal device using both the device class and the Bluetooth address. In any case, by using the identification information for specifying the terminal device, it is possible to list the terminal devices that should not be connected, that is, to create a black list.

<Example 2>
In the second embodiment, the connection with the wireless controller 10 corresponding to the game machine 20 is efficiently realized, and the time required for establishing the connection with the wireless controller 10 is shortened. In the first embodiment, the addresses of terminal devices that are not compatible with the game machine 20 are stored as a blacklist. However, in the second embodiment, the address of the wireless controller 10 that is compatible with the game machine 20 is previously called as a call candidate. Register as a list. Thereby, the game machine 20 can be called without making an inquiry and can establish a connection in a short time.

  In the second embodiment, the game machine 20 needs to know the identification information of the wireless controller 10 in advance, that is, Bluetooth_ADDR, which is an address unique to the Bluetooth terminal. When the game machine 20 and the wireless controller 10 are sold as a set, the identification information of the wireless controller 10 may be registered in the list storage unit 112 of the game machine 20 in advance.

  When the game machine 20 is powered on, the game machine 20 calls the Bluetooth_ADDR registered in the list storage unit 112. If the registered wireless controller 10 exists around the game machine 20, the wireless controller 10 responds to the call, so that the connection is established in a short time.

  When the power to the game machine 20 is turned on and the identification information of the wireless controller 10 is not registered in the list storage unit 112 of the game machine 20, the inquiry unit 116 makes a connection inquiry, that is, an inquiry through the transmission unit 120. Nearby terminal devices send back responses. In the first embodiment, the identification information of the terminal device that has returned an unexpected ACK is recorded as a blacklist. However, in the second embodiment, the control unit 110 returns a ACK in accordance with a predetermined data format. The device identification information is recorded in the list storage unit 112 as a call candidate list. For this reason, the list storage unit 112 holds the identification information of the wireless controller 10 sold by, for example, an authorized manufacturer.

  When the control unit 110 registers the identification information of the legitimate wireless controller 10 in the list storage unit 112, the inquiry unit 116 does not make a connection inquiry when the next connection is established, for example, at the next power-on. . When the calling unit 118 directly calls the wireless controller 10 registered in the call candidate list, the connection inquiry, that is, the inquiry can be omitted, and the time required for establishing the connection can be shortened. For example, the connection inquiry may be performed when the power is turned on for the first time, and when the power is turned on thereafter, the connection inquiry is not performed and the call is made directly. For example, a button for operating the inquiry unit 116 may be provided on the game machine 20 main body, and when the user presses this button, the inquiry unit 116 may be controlled to make a connection inquiry, that is, an inquiry.

  Further, the inquiry unit 116 may make a connection inquiry for a predetermined time when the next connection is established, and stop the connection inquiry when the predetermined time is exceeded. By setting a certain limit on the search time of the peripheral wireless controller 10, it is possible to avoid a situation in which a long time is spent on connection inquiry. When the predetermined time is exceeded, the connection inquiry is stopped, and the calling unit 118 calls the wireless controller 10 registered in the call candidate list.

  The user can freely add to or delete from the call candidate list. When the user issues a registration deletion instruction for a wireless controller registered in the list storage unit 112 using the wireless controller 10, the registration deletion instruction is received by the deletion instruction reception unit 104, and the control unit 110 deletes the registration. Based on the instruction, the corresponding identification information is deleted from the list storage unit 112. Regarding addition of the wireless controller 10 to the call candidate list, the control unit 110 can register corresponding identification information in the list storage unit 112 based on an addition instruction from the user. Thereby, the user can actively add or delete the specific wireless controller 10 to the call candidate list without performing the inquiry process by the inquiry unit 116. At this time, if a name or the like can be assigned to Bluetooth_ADDR, management becomes easy for the user. As described above, the connection inquiry by the game machine 20 may be performed at an arbitrary timing by pressing a button for driving the inquiry unit 116 provided in the game machine 20 main body.

  Here, it is assumed that the wireless controller 10 registered in advance and the new wireless controller 10 are simultaneously connected to the game machine 20. When the game machine 20 is turned on, the wireless controller 10 registered in the call candidate list is automatically called to establish a connection. After the connection establishment with the registered wireless controller 10 is completed, a data transfer mode is entered for this wireless controller 10, but a connection inquiry and a call-in period are provided with the new wireless controller 10. This period may be set in accordance with, for example, the time until the game machine 20 main unit completes booting, that is, the time until key input in the game is prompted, the time until the game actually starts, and the like.

  The time until the key input is prompted is sufficient to establish a connection with the new wireless controller 10. Further, the time until the game is started is a sufficiently long time. For example, assuming that there are many new wireless controllers 10, such a time may be secured. A game normally requires the user to set a character or the like at the start, but it is used that the latency of communication between the game machine 20 and the wireless controller 10 is not so severe during this period. When a connection is established with the new wireless controller 10, the control unit 110 registers the identification information of the wireless controller 10 in the list storage unit 112. As a result, when a connection is established from the next time onward, a call is made to the newly added wireless controller 10 using the call candidate list without making an inquiry or making an inquiry for a predetermined short time. It is possible to shorten the connection time.

  For example, in the above-described embodiment, the connection control is performed in the application layer. However, as a modification, the connection control may be performed in the lower link management layer. In the Bluetooth protocol, security is managed by a link key. As a premise for establishing a connection between a master and a slave, each terminal device registers security parameters based on a link key set between two terminals. The terminal device determines connection authentication based on the set parameters. For the terminal device in which an authentication error has occurred as a result of this connection authentication, the identification information is stored in the database blacklist in the link management layer. You may register with. This makes it possible to determine whether or not connection is possible before processing in the upper application layer.

  Further, as a stage before generating a black list in the application layer, a list of terminal device lists (hereinafter referred to as “gray list”) to be registered in the black list may be generated. This gray list may be generated based on the reception intensity or the like in the master. A terminal device whose reception intensity is equal to or less than a predetermined threshold is registered in the gray list, and when the same situation is counted a predetermined number of times in the next connection process, the terminal device is registered in the black list. For the terminal device registered in the black list, the master does not make an inquiry and does not make a connection.

  At this time, even if it is once registered in the gray list, the terminal device may be deleted from the gray list if the reception strength exceeds a predetermined threshold before being registered in the black list. preferable. This is because, when the reception intensity is weak, it is considered that the user voluntarily moves to a position where the reception intensity becomes strong in order to improve the communication failure. In order to be cautious about registration in the black list, the number of times the reception strength is determined before registration in the black list may be set to a relatively large number of times, for example, several tens.

  As a further modification, the master can download and hold the black list from the outside. This download may be performed via a wireless line or may be performed via a wired line. When terminal devices that should not be connected are known in advance, it is possible to omit the process of creating a black list by the master itself by acquiring a list describing these terminal devices from the outside. In this case, it is preferable that the master itself has a function of creating a black list, and as an auxiliary function, the black list can be downloaded from the outside.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements and processing processes, and such modifications are also within the scope of the present invention. is there.
