Description

  The present invention relates to an information communication device such as a personal computer (PC) that transmits / receives information to / from a terminal device such as a digital camera or a mobile phone.

  In recent years, there are some devices that do not require the trouble of attaching / detaching a memory card or connecting a USB cable by performing short-range wireless communication for transmitting / receiving information between a terminal device such as a digital camera and an information communication device (for example, , See Patent Document 1). In this case, the user's intention to transfer data is determined based on whether or not the terminal device is installed in a predetermined wireless communication area, and the terminal device is installed in a predetermined wireless communication area. There is a problem such as requiring a large-scale detection means for detecting the occurrence.

  On the other hand, a proximity wireless communication technology that eliminates such problems and establishes a communication path simply by bringing devices that want to communicate with each other close to each other and can communicate a large amount of data at high speed is called “TransferJet”. Proposed. According to such close proximity wireless communication, since the transmission power is weak, it does not interfere with other wireless systems, and it is 1 by making it close to a close range within several centimeters with respect to a counterpart device to communicate with. Since the one-to-one communication is established, it is easy to specify the counterpart device and clearly reflect the user's intention of data transfer.

  In order to perform such close proximity wireless communication using electromagnetic waves, each device needs to have a communication means equipped with a dedicated antenna component. Here, for example, in order to make it possible to retrofit close proximity wireless communication between a PC and a terminal device such as a digital camera and to improve convenience, on the PC side, an antenna dedicated to close proximity wireless communication is disposed and the terminal device is disposed. There is a communication stage (hereinafter referred to as a stage) referred to as a cradle or the like that can be connected to the PC body with a USB cable or the like. According to this, the user can perform close proximity wireless communication with the PC side simply by placing a terminal device including a communication unit equipped with a dedicated antenna component on the stage.

  On the other hand, the PC 100 according to the first embodiment includes a general-purpose PC main body 101 and a stage 160 connected to the PC main body 101 with a USB cable 150, and an antenna component dedicated to close proximity wireless communication is mounted on the stage 160. Thus, close proximity wireless communication with such a wireless communication terminal 200 is possible.

  FIG. 3 is a perspective view schematically showing a configuration example of the stage 160, and FIG. 4 is a cross-sectional view schematically showing a configuration example of the stage 160. As shown in FIGS. 1, 3, etc., the stage 160 according to the first embodiment is formed in a size that allows a plurality of, for example, a maximum of four wireless communication terminals 200 to be arranged. The shape of the stage 160 is not particularly limited. For example, the stage 160 is formed in a circular shape.

  In such a stage 160, an antenna 161 for close proximity wireless communication is arranged. Here, for the sake of convenience, the antenna 161 is shown in the central portion of the stage 160 in FIG. 1, but as shown in FIGS. 3 and 4, the antenna 161 is provided over almost the entire area. Regardless of the position of the wireless communication terminal 200 placed on the stage 160, a substantially equivalent communication state is established with the wireless communication terminal 200. Further, a proximity wireless communication unit 162 as a communication means is provided in the stage 160 (see FIG. 5). The proximity wireless communication unit 162 uses the antenna 161 dedicated for proximity wireless communication to perform proximity wireless communication using radio waves on a single channel that has a one-to-one relationship with the counterpart device. Is. Basically, one-to-one communication is established when a partner device enters a close range within a few centimeters of close proximity wireless communication and responds to a connection request at regular or predetermined timing from the partner device. Send and receive information.

  In addition, on the surface of the stage 160, four placement indexes 163 that serve as a guide for the position where the wireless communication terminal 200 should be placed are written in a circular shape, for example. Further, in each placement index 163, a priority index 164 indicating a communication priority set in advance according to the position on the stage 160 is represented by numbers 1 to 4, for example, so that the user can understand. Further, on the surface side of the stage 160, in addition to the antenna 161, four position detection sensors 165 (S1, S2, S3, S3, S3, S3, S3, Are arranged corresponding to the positions in each arrangement index 163. The detection outputs of these position detection sensors 165 are used to detect that the wireless communication terminal 200 is placed on the stage 160 and to specify the position on the stage 160. The same priority as the corresponding priority index 164 is assigned to the sensor 165 in advance. That is, the priority is set as S1> S2> S3> S4.

  Here, as the position detection sensor 165, for example, an infrared sensor, a pressure sensor, a touch sensor, or an illuminance sensor can be used. The infrared sensor is a sensor that receives light having a wavelength in the infrared region with a light receiving element and photoelectrically converts the light to extract necessary information. When applied to the first embodiment, the wireless communication terminal 200 irradiates infrared rays. What is necessary is just to comprise so that reflected light may be received if it has been arrange | positioned and reflected light will not be received if it is not arrange | positioned. The pressure sensor is a sensor that measures the pressure from the outside with a pressure-sensitive element through a diaphragm (such as a stainless diaphragm or a silicon diaphragm), converts the pressure into an electric signal, and outputs the electric signal. In the case of a semiconductor piezoresistive diffusion pressure sensor, a semiconductor strain gauge is formed on the surface of the diaphragm, and the electric due to the piezoresistive effect generated by deformation of the diaphragm due to external pressure due to the wireless communication terminal 200 being disposed. A change in resistance may be converted into an electrical signal and output.

  The hardware configuration of the PC main body 101 is not particularly limited and may be a known general-purpose PC, and the description thereof is omitted. The PC main body 101 includes a control unit 110 mainly including a CPU. FIG. 5 is a schematic block diagram mainly showing a functional configuration example of the control unit 110 in the PC 100. The control unit 110 according to the first embodiment includes a session management unit 111, an arrangement detection / position specifying unit 112, a priority determination unit 113, a communication control unit 114, and a sensor control unit 115 that are executed by the CPU based on a control program. A functional part is provided.

  The session management unit 111 is used to generate a session and start communication when close proximity wireless communication with the counterpart device is established, and to perform session management associated with suspension and restart of close proximity wireless communication. Known techniques such as session management are used. The arrangement detection / position specifying unit 112 arranges the wireless communication terminal 200 on the stage 160 using the detection output of the position detection sensors 165 (S1 to S4) whose priority is set according to the position on the stage 160. In addition, a process of specifying the position on the stage 160 of the wireless communication terminal 200 that has been detected to be newly placed on the stage 160 is executed. The priority determination unit 113 determines the proximity by the proximity wireless communication unit 162 of the plurality of wireless terminal devices 200 arranged on the stage 160 according to the position on the stage 160 specified by the arrangement detection / position specifying unit 112. A process of determining the priority of wireless communication is executed. The sensor control unit 115 controls the operation timing of the position detection sensor 165.

  Further, the communication control unit 114 performs close proximity wireless communication so as to sequentially perform close proximity wireless communication with a plurality of wireless communication terminals 200 arranged on the stage 160 according to the communication priority determined by the priority determination unit 113. The process which controls 162 is performed. More characteristically, when the arrangement detection / position identification unit 112 detects that the first wireless communication terminal 200 is newly arranged on the stage 160 and identifies the position on the stage 160, communication is performed. The control unit 114 determines that the priority of the first wireless communication terminal 200 determined by the priority determination unit 113 according to the position on the stage 160 is the second wireless communication terminal currently communicating with the proximity wireless communication unit 162. When the priority is higher than 200, the proximity wireless communication unit 162 interrupts the proximity wireless communication with the second wireless communication terminal 200 and interrupts and starts the proximity wireless communication with the first wireless communication terminal 200. To control.

  An example of communication control executed by the control unit 110 when a plurality of wireless communication terminals 200 are arranged on the stage 160 in such a configuration will be described. FIG. 6 is a schematic flowchart illustrating an example of communication control executed by the control unit 110. First, a connection request is issued from the antenna 161 of the close proximity wireless transfer unit 162 arranged on the stage 160 to an unspecified partner device (step S100), and it is determined whether there is a response from the partner device (step S101). . This connection request is issued periodically unless data transfer is in progress. Here, when the wireless communication terminal 200 is arranged on the stage 160 so as to be a close distance to the antenna 161, there is a response that an “OK” signal is returned (step S101; Yes), but there is no response. (Step S101; No), it returns to Step S100 on the assumption that there is no counterpart device within a communicable close range.

  When the wireless communication terminal 200 is arranged on the stage 160 and there is a response to the connection request (step S101; Yes), at this time, the position detection sensor is provided via the sensor control unit 115. 165 is turned on to enable the detection operation (step S102). The placement detection / position specifying unit 112 detects that the wireless communication terminal 200 is placed on the stage 160 based on the detection output of any of the position detection sensors 165 (S1 to S4), and the position where the detection output is present. Based on the position of the detection sensor 165 (S1 to S4), the position of the wireless communication terminal 200 on the stage 160 is specified.

  Further, it is determined whether there is an interrupted session (step S103). Here, the interrupted session is a session generated by interrupting close proximity wireless communication with the currently communicating wireless communication terminal 200 when there is a wireless communication terminal 200 with high priority. If there is no suspended session (step S103; No), the communication control unit 114 establishes a one-to-one close proximity wireless communication between the wireless communication terminal 200 that has responded and the close proximity wireless communication unit 162 and performs wireless communication. Data transfer is executed from the communication terminal 200 side to the PC 100 side (step S104). When the data transfer is completed (step S105; Yes), the process returns to step S100 and a new connection request is issued.

  On the other hand, when the data transfer is not completed (step S105; No), it is determined at any time whether there is a sensor input from the position detection sensor 165 (S1 to S4) provided on the stage 160 (step S106). ). This is to detect whether a new wireless communication terminal 200 is placed on the stage 160 during communication. If there is no sensor input (step S106; No), the data transfer in step S104 is continued. When there is a sensor input (step S106; Yes), the arrangement detection / position specifying unit 112 detects that the radio communication terminal 200 (first terminal device) is newly arranged on the stage 160. Based on the position of the position detection sensor 165 that has received the sensor input, the position of the newly placed wireless communication terminal 200 on the stage 160 is specified (step S107). And the priority determination part 113 determines the priority of the communication regarding the radio | wireless communication terminal 200 newly arrange | positioned according to the specified position (step S108). This priority is determined according to the priority assigned in advance to each position detection sensor 165 (S1 to S4) according to the position of the sensor.

  Thereafter, the communication control unit 114 determines whether or not the priority of the newly placed wireless communication terminal 200 is higher than the priority of the wireless communication terminal 200 (second terminal device) that is currently communicating ( Step S109). If the priority is not high (step S109; No), the process returns to step S104, and the data transfer with the wireless communication terminal 200 currently communicating is continued.

  On the other hand, when the priority of the newly arranged wireless communication terminal 200 is higher (step S109; Yes), the communication control unit 114 does not cause the currently communicating wireless communication terminal 200 to respond to the connection request. The sleep time (T_sleep) is set to the maximum (step S110), and an interruption request is issued to the currently communicating wireless communication terminal 200 (step S111). In response to this, the wireless communication terminal 200 that is currently communicating responds “OK” to the interruption request, and starts the operation of the sleep timer, thereby communicating with the close proximity wireless communication unit 162 on the PC 100 side. Interrupt.

  Further, the communication control unit 114 issues a connection request to an unspecified partner device from the antenna 161 of the close proximity wireless communication unit 162 (step S112), and determines whether there is a response from the partner device (step S113). . At this time, since the wireless communication terminal 200 that is currently communicating is in a sleep state and cannot respond to the connection request, the wireless communication terminal 200 with a high priority newly placed on the stage 160 becomes a connection request. It becomes possible to respond to it.

  If there is a response (step S113; Yes), it is determined whether the session is being interrupted (step S114). In consideration of the fact that there may be a wireless communication terminal 200 in which three or more wireless communication terminals 200 are simultaneously arranged on the stage 160 and communication has already been interrupted. This is because it is possible to establish communication with the wireless communication terminal 200 newly arranged on the stage 160 regardless of the existence. Therefore, if the session is interrupted (step S114; Yes), the process returns to step S110, and the wireless communication terminal 200 is again set to the maximum sleep time to interrupt communication. Therefore, the maximum sleep time (T_sleep) is set as a time during which a maximum of three wireless communication terminals 200 minutes can not respond to a connection request even when looped.

  Then, when there is a response (step S113; Yes), the communication control unit 114 is not a suspended session (step S114; No), and the new wireless communication terminal 200 and the proximity wireless communication unit 162 that have responded. One-to-one proximity wireless communication is established between the wireless communication terminal 200 and the wireless communication terminal 200 to perform data transfer from the wireless communication terminal 200 side to the PC 100 side (step S104). When the data transfer is completed (step S105; Yes), the process returns to step S100 and a new connection request is issued.

  When there is a response to this connection request (step S101; Yes), if it is a suspended session (step S103; Yes), whether or not the priority is the highest among the suspended sessions. Determination is made (step S115). If the priority is not the maximum (step S115; No), the sleep time is set to the maximum again for the wireless communication terminal 200 (step S116), the process returns to step S100, and the higher priority wireless communication terminal Communication with 200 is made possible. When the priority is the highest (step S115; Yes), the one-to-one proximity wireless communication is established again with the suspended wireless communication terminal 200 that has responded, and the wireless communication terminal 200 side to the PC 100 side. Data transfer is executed (step S104).

  Next, a sequence example of the system according to the communication control example shown in FIG. 6 will be described. FIG. 7 shows that after the wireless communication terminal 200 (second terminal device) indicated by MS1 is arranged at the second position on the stage 160, as shown in FIG. FIG. 6 is a schematic sequence diagram showing a sequence example when the terminal device is placed at the first position on the stage 160.

  First, in a situation where a connection request is periodically issued from the antenna 161, when the MS1 is arranged at the second position on the stage 160, the proximity of the MS1 and the PC 100 by the “OK” response to the subsequent connection request. One-to-one close proximity wireless communication is established with the wireless communication unit 162, and data transmission by data transmission from the MS1 side and data reception by the PC100 side is executed. Prior to this, on the PC 100 side, the position detection sensor 165 of the stage 160 is turned on to enable the detection operation. Thereby, it is specified that MS1 is arranged on stage 160 and that the position is the detection output of position detection sensor 165 indicated by S2, so that MS1 is arranged at the second position.

  While the data transfer is being executed, the sensor is waiting for sensor input from the position detection sensor 165, and the position detection indicated by S1 indicates that MS2 is placed at the first position on the stage 160 while the data transfer is not completed. When detected by the sensor 165, sensor interrupt processing is executed based on the output of the position detection sensor 165. In this sensor interrupt processing, it is specified that the MS 2 is arranged on the stage 160 and that the arrangement position is the first position on the stage 160. As a result, it is also determined that the communication priority of MS2 is the first.

  Therefore, when the priority of the currently communicating MS1 is compared with the priority of the newly allocated MS2, the priority of the newly allocated MS2 is higher, so that an interruption request with the sleep time set to the maximum is issued. Issued to the MS 1 currently in communication. The MS 1 that has received the interruption request responds with an “OK” signal and starts a sleep timer to interrupt communication. The session at this time is managed as a suspended session.

  On the other hand, in response to the response of the “OK” signal from the MS 1 side, the PC 100 issues a connection request from the antenna 161. At this time, the MS 1 side is in a sleep state and cannot respond to the connection request, whereas the newly arranged MS 2 with high priority can respond to the connection request with an “OK” signal. With this “OK” response from the MS2 side, one-to-one close proximity wireless communication is established between the MS2 and the close proximity wireless communication unit 162 of the PC 100, data transmission from the MS2 side, and data transfer by data reception on the PC 100 side Is executed. Thereafter, the transmission completion end process is executed in the MS 2, whereby the communication between the MS 2 and the PC 100 ends.

  When the PC 100 completes the reception with the transmission completion processing in the MS 2, it issues a connection request from the antenna 161. As a result, the sleep timer is timed up, and the MS 1 that has interrupted communication can respond. Due to the “OK” response from the MS 1 side, the one-to-one close proximity wireless communication is established again between the MS 1 and the close proximity wireless communication unit 162 of the PC 100, the data transmission from the MS 1 side is resumed, and the data reception on the PC 100 side is performed. Data transfer is executed. When this transmission is resumed, the session of the MS 1 is managed by the session management unit 111. Thereafter, the transmission completion end process is executed in the MS 1, whereby the communication between the MS 1 and the PC 100 ends. On the PC 100 side, the reception is completed along with the transmission completion processing in the MS 1, and thereafter, the connection request is repeated in the same manner and a new communication is established.

  On the other hand, FIG. 8 shows that after the wireless communication terminal 200 (second terminal device) indicated by MS1 is arranged at the second position on the stage 160, the wireless communication terminal 200 (first terminal device) indicated by MS2 is FIG. 6 is a schematic sequence diagram showing an example of a sequence when it is arranged at a third position on the stage 160.

  First, in a situation where a connection request is periodically issued from the antenna 161, when the MS1 is arranged at the second position on the stage 160, the proximity of the MS1 and the PC 100 by the “OK” response to the subsequent connection request. One-to-one close proximity wireless communication is established with the wireless communication unit 162, and data transmission by data transmission from the MS1 side and data reception by the PC100 side is executed. Prior to this, on the PC 100 side, the position detection sensor 165 of the stage 160 is turned on to enable the detection operation. Thereby, it is specified that MS1 is arranged on stage 160 and that the position is the detection output of position detection sensor 165 indicated by S2, so that MS1 is arranged at the second position.

  While the data transfer is being executed, the sensor is waiting for sensor input from the position detection sensor 165, and the position detection indicated by S3 indicates that MS2 is arranged at the third position on the stage 160 while the data transfer is not completed. When detected by the sensor 165, sensor interrupt processing is executed based on the output of the position detection sensor 165. In this sensor interrupt processing, it is specified that the MS 2 is arranged on the stage 160 and that the arrangement position is the third position on the stage 160. As a result, it is also determined that the communication priority of MS2 is No. 3.

  Therefore, comparing the priority of the currently communicated MS1 with the priority of the newly placed MS2, the priority of the newly placed MS2 is lower, so unlike the case of FIG. Data transfer between the MS 1 in the middle and the PC 100 is continued. Thereafter, the transmission completion end process is executed in the MS 1, whereby the communication between the MS 1 and the PC 100 ends.

  When the PC 100 side completes the reception with the transmission completion processing in the MS 1, it issues a connection request from the antenna 161. As a result, the MS 2 waiting on the stage 160 can respond. With this “OK” response from the MS2 side, one-to-one close proximity wireless communication is established between the MS2 and the close proximity wireless communication unit 162 of the PC 100, data transmission from the MS2 side, and data transfer by data reception on the PC 100 side Is executed. Thereafter, the transmission completion end process is executed in the MS 2, whereby the communication between the MS 2 and the PC 100 ends. On the PC 100 side, the reception is completed with the transmission completion processing in the MS 2, and thereafter, the connection request is repeated in the same manner and a new communication is established.

  As described above, according to the first embodiment, communication priority is set in advance according to the position on the stage 160, and a plurality of wireless communication terminals 200 are arranged on the stage 160 on which the antenna 161 is arranged. When arranged at the same time, the communication priority is determined according to the position on the arranged stage 160, and a plurality of wireless communication terminals 200 are sequentially communicated according to the determined priority. Even when there are a plurality of wireless communication terminals 200 that wish to perform close proximity wireless communication while simultaneously using the close proximity wireless communication method of 1, it is possible to respond appropriately.

Proximity wireless communication is possible.

  FIG. 10 is a perspective view schematically showing a configuration example of the stage 170, and FIG. 11 is a cross-sectional view schematically showing a configuration example of the stage 170. As shown in FIGS. 9, 10, and the like, the stage 170 according to the second embodiment is formed in a size that allows a plurality of, for example, a maximum of four wireless communication terminals 200 to be arranged. The shape of the stage 170 is not particularly limited. For example, the stage 170 is formed in a circular shape.

  An antenna 171 for close proximity wireless communication is arranged on the surface side in such a stage 170. Here, for example, five antennas 171 are arranged dispersedly as indicated by A1 to A5 in FIG. These five antennas 171 (A1 to A5) are in communication with at least one of the antennas 171 regardless of the position of the radio communication terminal 200 disposed on the stage 170. It is configured so that it can be established. In addition, a proximity wireless communication unit 172 as a communication unit is provided in the stage 170 (see FIG. 12). The close proximity wireless communication unit 172 uses any one of the close proximity wireless communication dedicated antennas 171 (A1 to A5), thereby allowing radio waves to be transmitted on a single channel having a one-to-one relationship with the counterpart device. Is used for close proximity wireless communication. Basically, a partner device enters a close range within a few centimeters at which close proximity wireless communication is possible, and a one-to-one communication is established by receiving a response from the partner device in response to a connection request at a predetermined timing, thereby transmitting / receiving information. Execute. Any one of the five antennas 171 indicated by A1 to A5 can be selected by an antenna changeover switch 173 (see FIG. 12) provided in the close proximity wireless transfer unit 172.

  In addition, on the surface of the stage 170, four placement indexes 163 serving as a guide for the position where the wireless communication terminal 200 should be placed are written in a circular shape, for example. Further, in each placement index 163, a priority index 164 indicating a communication priority set in advance according to the position on the stage 170 is expressed by numbers 1 to 4, for example, so that the user can understand. Here, among the five antennas 171, the four antennas 171 indicated by A <b> 1 to A <b> 4 are also used for position detection of the wireless communication terminal 200, and are arranged corresponding to the positions of the respective arrangement indexes 163. Yes. The same priority as the corresponding priority index 164 is assigned in advance to the antennas 171 indicated by A1 to A4. Further, the antenna 171 indicated by A5 is disposed at the center position on the stage 170 so as to be common to the respective placement indexes 163, and is dedicated to close proximity wireless communication.

  The hardware configuration of the PC main body 101 is not particularly limited and may be a known general-purpose PC, and the description thereof is omitted. The PC main body 101 includes a control unit 120 mainly composed of a CPU. FIG. 12 is a schematic block diagram mainly showing the functional configuration of the control unit 120 in the PC 100. The control unit 120 according to the second embodiment includes a session management unit 121, an arrangement detection / position specifying unit 122, a priority determination unit 123, a communication control unit 124, a transmission rate detection unit 125, and the like that are executed by the CPU based on a control program. Each function part of the communication antenna determination part 126 is provided.

  The session management unit 121 is the same as the session management unit 111 described above. The communication antenna determination unit 126 serving as an antenna selection unit selects one of the antennas used for communication by sequentially selecting and switching the five antennas 171 (A1 to A5) arranged on the stage 170 via the antenna switching switch 173. As will be described later, different processes are executed between the polling process and the actual communication.

  The transmission rate detecting unit 125 as a communication speed measuring unit determines the communication speed when communicating with the wireless communication terminal 200 via one antenna 171 selected by the antenna changeover switch 173 under the control of the communication antenna determining unit 126. A process for detecting the transmission rate is executed. The detection result of the transmission rate for each antenna 171 by the transmission rate detection unit 125 is the detection of the arrangement of the wireless communication terminal 200 with respect to the stage 170 and the position thereof, and the antenna 171 used for actual communication. Used for selection.

  The placement detection / position specifying unit 122 performs wireless communication terminal 200 via any one of antennas A1 to A5 that are sequentially switched by the antenna switching switch 173 under the control of the communication antenna determination unit 126 during the polling process. And detecting that the wireless communication terminal 200 is placed on the stage 170 based on the result of the communication connection, and specifying the position of the wireless communication terminal 200 placed on the stage 170 on the stage 170 . Here, the detection result of the transmission rate detected by the transmission rate detection unit 125 is used as a result of the communication connection. That is, when communication is established with the wireless communication terminal 200 by sequentially switching the antennas 171 of A1 to A5 and issuing a connection request, it is detected that the wireless communication terminal 200 is disposed at least on the stage 170. Is done. In addition, when communication is established, the transmission rate by the antenna 171 closest to the arranged wireless communication terminal 200 is maximized, and therefore the antenna 171 having the maximum transmission rate among A1 to A4 is obtained. An arrangement position can be specified in the position.

  The priority determination unit 123 prioritizes proximity wireless communication by the proximity wireless communication units 172 of the plurality of wireless terminal devices 200 arranged on the stage 170 according to the position specified by the arrangement detection / position specifying unit 122. Execute the process to determine. Further, as in the case of the communication control unit 114 described above, the communication control unit 124 and the plurality of wireless communication terminals 200 arranged on the stage 170 sequentially in accordance with the priority determined by the priority determination unit 123. A process of controlling the close proximity wireless transfer unit 172 so as to perform communication is executed. When the near field communication unit 172 actually communicates with the wireless communication terminal 200 under the control of the communication control unit 124, the communication antenna determination unit 126 performs polling among the five antennas 171 indicated by A1 to A5. The antenna changeover switch 173 is controlled so as to select the antenna 171 having the maximum transmission rate (the communication speed is the fastest) measured by the transmission rate detection unit 125 during processing. That is, the antenna 171 indicated by A5 in the center is not used for priority determination, but when the maximum transmission rate is obtained by using this antenna A5, control is performed so that communication is performed using this antenna A5. Is done.

An example of communication control executed by the control unit 120 when a plurality of wireless communication terminals 200 are arranged on the stage 170 in such a configuration will be described. FIG. 13 is a schematic flowchart illustrating an example of communication control executed by the control unit 120. First, the wireless communication terminal 200 is placed on the stage 170, the position thereof is specified, and further, polling processing for detecting the transmission rate by each antenna is executed (step S200).

  FIG. 14 is a subroutine showing a control example of the polling process in step S200. First, the communication antenna determination unit 126 sets n = 1 as a variable n related to the antenna 171 (step S210). Then, the antenna selector switch 173 selects the antenna to be used by switching to the antenna An (n = 1 to 5) corresponding to the variable n (step S211). Therefore, a connection request is issued from this antenna An to an unspecified partner device (step S212), and it is determined whether or not there is a response from the partner device (step S213). Here, when the wireless communication terminal 200 is arranged on the stage 170 so as to be close to the antenna An, an “OK” signal is returned (step S213; Yes), but there is no response. (Step S213; No), the process proceeds to Step S217.

  If there is a response (step S213; Yes), it is determined whether the session is being interrupted (step S214). Here, the interrupted session is a session generated by interrupting close proximity wireless communication between the antenna An and the currently communicating wireless communication terminal 200 when there is a high priority wireless communication terminal 200. . If it is a suspended session for the antenna An (step S214; Yes), the sleep time (T_sleep) for preventing the antenna An from responding to the connection request is set to the maximum (step S215), The process returns to step S211. That is, in the case of a suspended session, the response to the connection request is canceled.

  If there is a response to the connection request from the antenna An (step S213; Yes), and if it is not a suspended session (step S214; No), between the selected antenna An and the wireless communication terminal 200 that has responded Then, one-to-one close proximity wireless communication is established, and the transmission rate is detected by the transmission rate detector 125 by executing the data transfer process, and the detected transmission rate is stored in a memory (not shown) (step S216).

  After this, if the variable n for the antenna 171 does not reach the maximum value N (N = 5) (step S217; No), the variable n is incremented by +1 (step S218), and the process returns to step S211. The same process is repeated for the next incremented antenna An. That is, with respect to the five antennas A1 to A5, processing for detecting whether or not to connect to the wireless communication terminal 200 and the transmission rate at the time of connection are sequentially performed one by one.

  When the variable n for the antenna 171 reaches the maximum value N (step S217; Yes), it is determined whether or not there is a response from the wireless communication terminal 200 other than the suspended session (step S219). Step S219; No), the process proceeds to step S221. On the other hand, when there is a response from the wireless communication terminal 200 other than the suspended session (step S219; Yes), session processing is performed (step S220).

  FIG. 15 is a schematic subroutine showing an example of session processing in step S220. First, the detection result of the transmission rate at each of the antennas A1 to A5 is acquired (step S230), and the antenna having the maximum transmission rate other than the middle antenna A5 (A1 to A4) is determined (step S231). Thereby, the arrangement detection / position specifying unit 122 specifies the position of the determined antenna (any one of A1 to A4) as the position where the wireless communication terminal 200 is arranged (step S232). Further, the priority determination unit 123 determines the communication priority of the wireless communication terminal 200 according to the specified position of the wireless communication terminal 200, that is, according to the priority assigned to the determined antenna. (Step S233). And while producing | generating the session used for communication, the priority determined to the session is set (step S234).

  In step S219, if there is a response for a plurality of antennas in the session processing in step S220, the communication antenna determination unit 126 determines the transmission rate used in the session from the transmission rates of the antennas A1 to A5. Decide to choose the largest antenna. Then, the session for which the maximum priority is set is selected (step S221).

  Returning to FIG. 13, when the polling process is executed in this way and the session with the highest priority is selected, the session with the highest priority is generated using one antenna 171 selected from A1 to A5. One-to-one close proximity wireless communication is established with the wireless communication terminal 200, and communication is started or restarted (step S201). Thereafter, when the data transfer is completed (step S202; Yes), the process returns to step S200, polling processing is executed, and the next communication is determined.

  On the other hand, when the search time (T_search) for periodically executing the detection process of the newly placed wireless communication terminal 200 is set and the data transfer is not completed (step S202; No) Then, it is determined whether the search time from the start of communication has timed out (step S203). When the search time has timed out (step S203; Yes), the sleep time (T_sleep) for preventing the currently communicating wireless communication terminal 200 from responding to the connection request is set to the maximum (step S204). ) An interruption request is issued to the wireless communication terminal 200 currently in communication (step S205), and the process returns to step S200. By this polling process, the detection process regarding the wireless communication terminal 200 newly arranged on the stage 170 can be performed.

  Next, a sequence example of the system according to the communication control examples shown in FIGS. 13 to 15 will be described. FIG. 16 shows a wireless communication terminal 200 (second terminal apparatus) indicated by MS1 after being placed at the second position (position of antenna A2) on stage 170, and then wirelessly indicated by MS2 as shown in FIG. FIG. 11 is a schematic sequence diagram showing a sequence example when communication terminal 200 (first terminal device) is arranged at the first position (position of antenna A1) on stage 170.

  First, polling processing is executed in a state where the wireless communication terminal 200 indicated by MS1 is placed at the second position on the stage 170, and it is detected that the MS1 is placed on the stage 170, and the antenna A2 It is specified that it is arranged at the position. Therefore, the antenna A2 having the maximum transmission rate is selected and a connection request is issued from the antenna A2. In response to an “OK” response from MS1 to this connection request, one-to-one close proximity wireless communication is established between MS1 and antenna A2 of close proximity wireless communication section 172 of PC 100, and search timer T_search is started, and MS1 side Data transmission from the PC 100 and data transfer by data reception on the PC 100 side are executed.

  It is assumed that the wireless communication terminal 200 indicated by MS2 is arranged at the first position on the stage 170 at an appropriate time during such communication. Here, when the search timer T_search times out during data transfer, the control unit 120 issues an interruption request with the sleep time set to the maximum to the currently communicating MS1. The MS 1 that has received the interruption request responds with an “OK” signal and starts a sleep timer to interrupt communication. The session at this time is managed as a suspended session. Then, the polling process is executed again.

  In this polling process, it is detected that MS2 is newly arranged on stage 170, and it is specified that MS2 is arranged at the position of antenna A1 having a higher priority than antenna A2. As a result, it is also determined that the communication priority of MS2 is the first.

  Then, with the end of the polling process, the antenna A1 with the maximum transmission rate is selected, and a connection request is issued from this antenna A1. At this time, the MS1 side is in a sleep state and cannot respond to the connection request even at a close distance, but the newly arranged MS2 responds to the connection request with an “OK” signal. It becomes possible. With this “OK” response from the MS2 side, a one-to-one proximity wireless communication is established between the MS2 and the antenna A1 of the proximity wireless communication unit 172 of the PC 100, and a search timer T_search is started. Data transmission by data transmission and data reception on the PC 100 side is executed. Thereafter, the transmission completion end process is executed in the MS 2, whereby the communication between the MS 2 and the PC 100 ends.

  When reception of the PC 100 is completed along with the transmission completion processing in the MS 2, the antenna A2 that has interrupted communication is selected, and a connection request is issued from the antenna A2. As a result, the sleep timer is timed up, and the MS 1 that has interrupted communication can respond. With this “OK” response from the MS 1 side, the one-to-one close proximity wireless communication is established again between the MS 1 and the antenna A 2 of the close proximity wireless communication unit 172 of the PC 100, the search timer T_search is started, and from the MS 1 side Data transmission is resumed, and data transfer is performed by receiving data on the PC 100 side. When the transmission is resumed, the session of the MS1 is managed by the session management unit 121. Thereafter, the transmission completion end process is executed in the MS 1, whereby the communication between the MS 1 and the PC 100 ends. On the PC 100 side, the reception is completed along with the transmission completion processing in MS1, and thereafter, the polling process is repeated in the same manner and a new communication is established.

  On the other hand, FIG. 17 shows a case where the wireless communication terminal 200 (second terminal apparatus) indicated by MS1 is arranged at the second position (position of the antenna A2) on the stage 170, and then the wireless communication terminal 200 (second terminal) indicated by MS2. 1 is a schematic sequence diagram showing a sequence example when the terminal device 1 is arranged at the third position (the position of the antenna A3) on the stage 170. FIG.

  First, polling processing is executed in a state where the wireless communication terminal 200 indicated by MS1 is placed at the second position on the stage 170, and it is detected that the MS1 is placed on the stage 170, and the antenna A2 It is specified that it is arranged at the position. Therefore, the antenna A2 having the maximum transmission rate is selected and a connection request is issued from the antenna A2. In response to an “OK” response from MS1 to this connection request, one-to-one close proximity wireless communication is established between MS1 and antenna A2 of close proximity wireless communication section 172 of PC 100, and search timer T_search is started, and MS1 side Data transmission from the PC 100 and data transfer by data reception on the PC 100 side are executed.

  It is assumed that the wireless communication terminal 200 indicated by MS2 is arranged at the third position on the stage 170 at an appropriate time during such communication. Here, when the search timer T_search times out during data transfer, the control unit 120 issues an interruption request with the sleep time set to the maximum to the currently communicating MS1. The MS 1 that has received the interruption request responds with an “OK” signal and starts a sleep timer to interrupt communication. The session at this time is managed as a suspended session. Then, the polling process is executed again.

  In this polling process, it is detected that MS2 is newly arranged on stage 170, and it is specified that MS2 is arranged at the position of antenna A3 having a lower priority than antenna A2. As a result, it is also determined that the communication priority of MS2 is No. 3.

  Therefore, after the time-up of the sleep timer on the MS1 side, a connection request is issued from the currently selected antenna A2. At this time, the MS 1 can respond to the connection request with an “OK” signal. By the “OK” response from the MS 1 side, the one-to-one close proximity wireless communication is established again between the MS 1 and the antenna A 2 of the close proximity wireless communication unit 172 of the PC 100, and the search timer T_search is started. The data transmission is resumed, and the data transfer by the data reception on the PC 100 side is executed again. Thereafter, the transmission completion end process is executed in the MS 1, whereby the communication between the MS 1 and the PC 100 ends.

  When reception of the PC 100 is completed along with the transmission completion processing in the MS 1, the antenna A3 is selected for communication with the MS 2 arranged at the position of the antenna A3 having the priority 3, and a connection request is issued from the antenna A3. Thereby, MS2 arrange | positioned in the position of antenna A3 can respond. By the “OK” response from the MS2 side, the one-to-one close proximity wireless communication is established again between the MS2 and the antenna A3 of the close proximity wireless communication unit 172 of the PC 100, and the search timer T_search is started. Data transmission and data transfer by data reception on the PC 100 side are executed. Thereafter, the transmission completion end process is executed in the MS 2, whereby the communication between the MS 2 and the PC 100 ends. On the PC 100 side, the reception is completed along with the transmission completion processing in the MS 2, and thereafter the polling process is repeated in the same manner and a new communication is established.

  In this way, according to the second embodiment, in addition to the effects of the first embodiment, wirelessly by providing a plurality of antennas 171 in a distributed manner without providing the position detection sensors 165 separately. Since it is possible to detect the position and position of the communication terminal 200 and to select the antenna 171 having the maximum transmission rate to perform communication, the wireless communication terminal 200 is arranged at any position on the stage 170. Even in this case, high-speed communication can be performed by selecting the antenna 171 having the optimum maximum transmission rate.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the PC main body 101 and the stages 160 and 170 are separately configured and connected by the USB cable 150. However, the PC main body 101 and the stages 160 and 170 are configured to include a stage integrally with the PC main body. Also good. FIG. 18 is a schematic perspective view showing an example of a notebook PC 100A integrally provided with a stage. The PC 100 </ b> A includes a keyboard 181 and a liquid crystal display 182 in a PC main body 180, and uses a palm rest portion in front of the keyboard 181 as a stage 183. A plurality of antennas 184 indicated by A1 to A4 are arranged on the stage 183, and an arrangement index 163 and a priority index 164 indicating communication priority are described. Also in this case, according to the first embodiment, one antenna may be arranged over the entire stage 183 and a position detection sensor may be arranged at the position of each arrangement index 163.

  In the above-described embodiment, the arrangement detection / position specifying units 112 and 122 perform both the process of detecting the arrangement of the wireless communication terminal 200 and the process of specifying the position, but the wireless communication terminal 200 for the stages 160 and 170 is used. , And the specification of the arrangement position of the wireless communication terminal 200 on the stages 160 and 170 may be performed separately and independently.

  In the second embodiment, the optimum antenna for communication is determined only when a session is generated. However, the optimum antenna for communication is determined at a predetermined interval or when another session is resumed. In this case, the priority may be updated. Furthermore, as a criterion for determining an antenna used for communication, not only the transmission rate but also a known parameter such as a received electric field strength may be used.

  Further, in the proximity wireless communication technology, as an optional specification, communication connection designating a partner device is possible. Therefore, if the device ID of a wireless communication terminal that can be a communication target is known in advance, an unspecified partner A wireless communication terminal newly placed on the stage may be found by making a connection request to a potential wireless communication terminal without controlling the sleep timer for use.
