Description

  The present invention relates to a registration device that registers a plurality of wireless communication terminals in a group, and a wireless communication terminal that is a target of group registration by the registration device.

In recent years, ETC has come to be used to automatically pay toll road charges, but the current ETC system does not provide a service that allows passengers to make payments on a split basis. Not as a system, there is a function to transfer ETC in-vehicle device information to the car navigation (Satellite navigation system) and perform split calculation in the car navigation). Therefore, in order to provide a service in which the passengers make a split payment, it is necessary to manage the passengers in groups.
As the “terminal recognition technology for grouping” proposed in recent years, the following prior art 1 to prior art 4 can be cited.

[Prior art 1]
In order for the vehicle-mounted device to recognize a terminal with a short-range wireless function in the vehicle, a plurality of antennas with a narrow directivity in the vehicle (for example, directivity that covers the vicinity of the seats on the left and right of the front row and the left and right sides of the rear row) This is a method (see Patent Document 1 and Patent Document 2) of arranging a short-distance wireless function-equipped terminal (mobile phone) by arranging an antenna having an antenna.
[Prior Art 2]
In order for the vehicle-mounted device to recognize the device with short-range wireless function in the vehicle, the device with short-range wireless function (mobile) with the highest electric field strength of the radio wave received by the vehicle-mounted device from the terminal with short-range wireless function (mobile phone) This is a method of selecting (telephone) (see Patent Document 3).
[Prior Art 3]
In order for the vehicle-mounted device to recognize a terminal with a short-range wireless function in the vehicle, the terminal with a short-range wireless function in which the electric field intensity of the radio wave received by the vehicle-mounted device from the terminal with the short-range wireless function (mobile phone) This is a method for selecting (mobile phone) (see Patent Document 4 and Patent Document 5).
[Prior Art 4]
In order for the in-vehicle device (Bluetooth device) to communicate with the in-vehicle device in order to recognize the device with the near-field wireless function in the vehicle, there are multiple connected near-field wireless function devices (Bluetooth devices), and When the vehicle speed of the vehicle equipped with the in-vehicle device (Bluetooth device) is higher than the specified value, the in-vehicle device (Bluetooth device) that was installed in the vehicle again communicated and was able to communicate in either situation from the two communication results. This is a method of determining a terminal with a short-range wireless function (Bluetooth device) as a terminal with a short-range wireless function (Bluetooth device) in a vehicle (see Patent Document 6).

JP-A-2005-328116 JP-A-2005-354122 JP-A-2005-260450 JP 2004-112257 A JP 2001-156704 A JP 2003-174669 A

Since the prior art 1 needs to provide a plurality (at least four) of antennas corresponding to each seat of the vehicle, there is a problem that the cost for hardware is high.
Prior art 2 and prior art 3 select a terminal with a short-range wireless function (mobile phone) having the highest electric field strength of radio waves received by the vehicle-mounted device. For example, when vehicles are running side by side in a traffic jam When a state in which a terminal with a short-range wireless function outside the vehicle is constantly approaching the vehicle occurs, the terminal with a short-range wireless function outside the vehicle is erroneously recognized as if it is in the vehicle. There is.
Prior art 4 performs, for example, the first communication (measurement) when the vehicle-mounted device (Bluetooth device) is turned on, and the second communication (measurement) when the vehicle starts and the vehicle speed exceeds a predetermined value. ) And the terminal with the short-range wireless function in the vehicle is specified from the result of the two communication (measurement), for example, the vehicle is temporarily stopped after the second communication (measurement) and a new short-range wireless function When a terminal with a short-range wireless function is turned on when the terminal with a short-range wireless function is turned on while the vehicle is running or when a terminal with a short-range wireless function is turned on while the vehicle is running There's a problem.
Therefore, when registering a plurality of terminals with short-range wireless functions using the prior art 1 to the conventional technique 4, a large amount of hardware is required, or the terminals with short-range wireless functions are erroneously registered in the above cases. Or a terminal with a short-range wireless function cannot be registered.

  An object of the present invention is to provide a technique (a registration device and a wireless communication terminal) that reliably registers a plurality of wireless communication terminals with a short-range wireless function while being low-cost.

  In order to achieve the above object, a registration device according to claim 1 of the present invention is a registration device for registering a plurality of wireless communication terminals in a group, and forms a group with a storage unit for storing identification information of the registration device. A registration unit that registers a wireless communication terminal that is a main of the plurality of wireless communication terminals using identification information of the wireless communication terminal, a message that prompts registration to the group when a predetermined condition is satisfied, and the main A transmission unit that transmits a request signal including identification information of a wireless communication terminal to be, a reception unit that receives a response signal including identification information of a registration device and identification information of a new wireless communication terminal, and the reception unit If the identification information of the registered device included in the response signal received by the above matches the registered device identification information stored in the storage unit, the new wireless communication terminal is registered to the group. And a control unit which is characterized by comprising comprises a.

  As a preferred example of the registration apparatus according to claim 1 of the present invention, the predetermined condition is that the moving speed of the registration apparatus exceeds a predetermined speed.

  In order to achieve the above object, a wireless communication terminal according to claim 3 of the present invention includes a storage unit that stores identification information of a predetermined wireless communication terminal, a message that prompts registration to the formed group, and the group A reception unit that receives a request signal including identification information of a main wireless communication terminal and identification information of a registration device that registers the group, and main wireless communication included in the request signal received by the reception unit When the identification information of the terminal matches the identification information of the wireless communication terminal stored in the storage unit, a response signal including information indicating registration to the group and the identification information of the registration device is transmitted. And a control unit for controlling.

  According to the present invention, when the identification information of the registration device included in the response signal received by the reception unit of the registration device matches the identification information of the registration device stored in the storage unit, the new wireless communication terminal is grouped. Therefore, it is not necessary to use a plurality of antennas with narrow directivity as in the prior art 1, and the terminal registration error or the terminal inability to register as in the prior art 2 to the prior art 4 Does not occur. Therefore, it is possible to provide a technique (registration apparatus and wireless communication terminal) for reliably registering a plurality of wireless communication terminals with a short-range wireless function in a group at a low cost.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing a schematic configuration of a communication system including an in-vehicle device and a wireless communication terminal which are registration devices of the present invention. This communication system is a registration device for registering a plurality of wireless communication terminals as a group, and has an in-vehicle device 100 equipped with a short-range wireless function (for example, Bluetooth) and a short distance of a plurality (in the case of FIG. 1, a total of five). And a wireless communication terminal (mobile phone) 200 with a wireless function (for example, Bluetooth). When a plurality of short-range wireless function-equipped wireless communication terminals (mobile phones) 200 are mounted on a vehicle on which the vehicle-mounted device 100 is mounted, a plurality of short-range wireless function-equipped wireless communication terminals (mobile phones) 200 are connected. A group can be registered as a group managed by the vehicle-mounted device. At that time, one of the plurality of short-range wireless function-equipped wireless communication terminals (cell phones) 200 registers the telephone number of the terminal in the in-vehicle device 100 as information for creating a group. “Terminal” is set, and the remaining wireless communication terminals are set as “sub-terminal candidates”. In the following, the plurality of short-range wireless function-equipped wireless communication terminals (mobile phones) are referred to as a main terminal 200M and sub-terminal candidates 200S1 to 200S4.

  As the vehicle-mounted device 100, an ETC vehicle-mounted device is used, but a vehicle navigation (Satellite navigation system) equipped with the function of the vehicle-mounted device of the present invention may be used. As shown in the functional block diagram of FIG. 2, the in-vehicle device 100 includes a storage unit 110, a registration unit 120, a transmission unit 130, a reception unit 140, a control unit 150, a short-range wireless unit 160, and speed measurement. Part 170 and a display part 180.

The storage unit 110 stores an in-vehicle device unique number 115 that is identification information of the in-vehicle device, a telephone number 230 of a main terminal described later, and the like.
The registration unit 120 uses a main terminal 200M that is a main wireless communication terminal of a plurality of short-range wireless function-equipped wireless communication terminals (mobile phones) 200 forming a group as a main terminal that is identification information of the main terminal. The phone number is used for registration.
When a predetermined condition is satisfied, the transmission unit 130 is a request signal including a message for prompting registration to the group and the telephone number of the main terminal. “Request: Enter in-vehicle device group” illustrated in FIG. And a message 220 including “telephone number of main terminal” and “vehicle equipment unique number” are transmitted to sub-terminal candidates 200S1 to 200S4 using short-range radio.
As will be described later, the predetermined condition is “when the moving speed of the in-vehicle device 100 (the same as the speed of the vehicle on which the in-vehicle device 100 is mounted) exceeds a predetermined speed (for example, 20 km / h)”. Note that a femtocell base station can also be used as the registration apparatus of the present invention. In this case, the predetermined condition is “when a sub-terminal is detected” and “from turning on (turning on) a femtocell base station” “When a predetermined time has elapsed”.

The receiving unit 140 is a response signal including the identification information of the registration device and the identification information of the new wireless communication terminal, as illustrated in FIG. 9, “response: enter in-vehicle device group” and “sub-terminal candidate” A message 240 including “phone number of (sub-terminal candidate 1)” and “vehicle equipment unique number” is received from sub-terminal candidate 200S1 to sub-terminal candidate 200S4 using short-range radio.
When the vehicle unit unique number included in the message 240 received by the reception unit 140 matches the vehicle unit unique number stored in the storage unit 110, the control unit 150 registers the new wireless communication terminal in the group. Is to control.
The short-range wireless unit 160 provides a short-range wireless function used when the transmission unit 130 and the reception unit 140 transmit and receive information such as messages between the main terminal 200M and the sub-terminal candidates 200S1 to 200S4. It is.
The speed measuring unit 170 is the same as the moving speed of the in-vehicle device 100 (the speed of the vehicle on which the on-vehicle device 100 is mounted, and the moving speed of the main terminal 200M and the sub terminal candidates 200S1 to 200S4 when mounted on the same vehicle). Is). Note that the speed measurement unit 170 can be provided outside the in-vehicle device 100, or a speed sensor mounted on the vehicle can be used.
The display unit 180 displays various information including main terminal registration screen information.

As shown in the functional block diagram of FIG. 3, the main terminal 200M and the sub terminal candidates 200S1 to 200S4 include a CPU 210, a voice control unit 211, a mobile phone baseband unit 212, a mobile phone radio unit 213, In addition to the storage device 215 storing the telephone book 214 and the short-range wireless unit 216, a speed measuring unit 217 that measures the moving speed of the terminal (which is the same as the vehicle speed), and a display unit that displays various information The speed measurement unit 217 is configured by, for example, a GPS device and software.
The storage device 215 functions as a storage unit that stores identification information of a predetermined wireless communication terminal (for example, the telephone number of the main terminal or the telephone number of the sub terminal).
The CPU 210 and the short-range wireless unit 216 function as a receiving unit that receives the message 220 that is a request signal transmitted from the in-vehicle device 100, and the telephone number of the main terminal included in the message 220 is stored in the storage device 215. If it matches the telephone number of the main terminal, it functions as a control unit that controls to transmit a message 240 that is a response signal including information indicating registration to the group and an in-vehicle device unique number.

  In order to function as the main terminal, the main terminal 200M needs to register the telephone number 230 of the main terminal 200M in the in-vehicle device 100 as illustrated in FIG. The telephone number 230 of the main terminal 200M is registered by wireless input from a wireless communication terminal (mobile phone) with a short-range wireless function using a short-range wireless function such as Felica technology or Bluetooth, or key input on the in-vehicle device 100. Can be performed. Note that the wireless communication terminal with short-range wireless function (mobile phone) set in the main terminal 200M is not always fixed to one wireless communication terminal with short-range wireless function (mobile phone). When the main terminal 200M no longer exists in the vehicle because the 200M user has left the vehicle, any one of the sub-terminals 200S1 to 200S4 is promoted to the main terminal 200M as described later. Further, the sub terminal candidates 200S1 to 200S4 are promoted to “sub terminals” when they are group-registered in the in-vehicle device 100, as will be described later.

[First Embodiment]
FIG. 5 is a flowchart showing the terminal recognition control according to the first embodiment performed by the in-vehicle device in the communication system according to the present invention. FIG. 6 shows the first embodiment performed by the sub terminal candidate in the communication system according to the present invention. It is a flowchart which shows terminal recognition control.

  First, in step S101 in FIG. 5, the vehicle-mounted device 100 is turned on (turned on) simultaneously with the vehicle accessory (ACC) power turned on (turned on). Thereafter, when the telephone number of the main terminal is input to the in-vehicle device 100 in order to register the telephone number of the main terminal, main terminal registration (registration of the main terminal telephone number) is performed in step S102.

  When inputting the telephone number of the main terminal wirelessly from a terminal with a short-distance wireless function (cell phone) using a short-distance wireless function such as Felica technology or Bluetooth, first, FIG. 7A or FIG. When “main terminal registration” is selected on the external connection setting screen illustrated in FIG. 7B, a confirmation screen illustrated in FIG. When “Yes” is selected on the confirmation screen, the telephone number of the terminal with short-range wireless function (mobile phone) is input to the in-vehicle device 100 using short-range wireless. Further, when the telephone number of a terminal with short-range wireless function (mobile phone) as a main terminal is directly input (key input) to the in-vehicle device 100, the display unit 180 of the in-vehicle device 100 is illustrated in FIG. Since the main terminal registration screen is displayed, a desired telephone number is entered using the numeric keypad in the telephone number frame of the main terminal registration screen.

  In the next step S103, speed measurement is performed. This speed measurement is repeated until the vehicle speed exceeds a predetermined speed (for example, 20 km / h) and Step S104 becomes Yes. When the vehicle speed exceeds the predetermined speed (for example, 20 km / h), the process proceeds to Step S105. In step S105, as shown in FIG. 1, a message (request signal) 220 composed of “request: enter in-vehicle device group”, “phone number of main terminal”, and “number unique to in-vehicle device” is displayed in a short distance. It transmits to sub terminal candidate 200S1 to sub terminal candidate 200S4 using radio.

  In response to the transmission of the message 220, the sub-terminal candidates (sub-terminal candidates 200S1 to 200S4; the sub-terminal candidate 1 in FIG. 6 are waiting for receiving the message in step S401 in FIG. 6). When the message 220 is received by the sub-terminal candidate 200S1), in the next step S402, it is confirmed whether or not the “phone number of the main terminal” is registered in the phone book of the own terminal. Here, if registered, the process proceeds to step S403 to perform speed measurement. If not registered, the process proceeds to step S406, and a response message is not returned to the in-vehicle device 100 as illustrated in FIG. Then, it ends as it is. If no response message is returned, the sub terminal candidate does not become a sub terminal. At that time, if the “phone number of the main terminal” is not registered in the phonebook of all the sub terminal candidates, no sub terminal candidate can be promoted to a sub terminal, and the group is composed only of main terminals. become. The speed measurement in step S403 is repeated until the vehicle speed exceeds a predetermined speed (for example, 20 km / h) and step S404 becomes Yes. When the vehicle speed exceeds the predetermined speed (for example, 20 km / h), the process proceeds to step S405. move on. In step S405, as shown in FIG. 9, a message (response) consisting of “response: enter in-vehicle device group”, “sub-terminal candidate (sub-terminal candidate 1) telephone number” and “in-vehicle device unique number”. Signal) 240 is returned to the vehicle-mounted device 100 using the short-range radio.

  When the message 240 is returned, a sub-terminal registration screen of candidate sub-terminals illustrated in FIG. 10 is displayed. The sub-terminal registration screen displays the vehicle-equipment unique number and the main terminal user name (main terminal User name corresponding to the telephone number) and Yes / No are displayed. When the user of the sub terminal confirms that “the desired main terminal belongs to the party to which the user belongs” and selects “Yes”, the sub terminal A message 240 including a telephone number is returned to the in-vehicle device 100 using short-range radio.

  The in-vehicle device 100 that has transmitted the message 220 in step S105 waits to receive a message from the sub terminal candidate in the next step S106, and therefore when the message 240 is returned to the in-vehicle device 100 in step S405. The message 240 is received in step S106. In the next step S107, it is confirmed whether or not the “vehicle equipment unique number” in the received message 240 matches the vehicle equipment unique number assigned to the vehicle equipment 100. Here, if the “vehicle equipment unique number” in the received message 240 matches the vehicle equipment unique number assigned to the vehicle equipment 100, “response: enter group of vehicle equipment” in the received message 240. The in-vehicle device 100 proceeds to step S108 and performs sub-terminal registration for adding the sub-terminal candidate as a sub-terminal to the group, and then, in step S109, “response” as illustrated in FIG. : A message 250 consisting of “permit to enter in-vehicle device group” is returned to the sub-terminal candidate (sub-terminal candidate 1) using the short-range radio. On the other hand, in step S107, if the “vehicle equipment unique number” in the received message 240 does not match the vehicle equipment unique number assigned to the vehicle equipment 100, “response: group of vehicle equipment” is received in the received message 240. After determining that “enter” is invalid and proceeding to step S110, the in-vehicle device 100 performs a process of refusing to add the sub-terminal candidate to the group, and then in step S111, as illustrated in FIG. A message 260 consisting of “response: not allowed to enter in-vehicle device group” is returned to the sub-terminal candidate (sub-terminal candidate 1) using the short-range radio.

  Since the sub terminal candidate (sub terminal candidate 1) that has transmitted the message 240 in step S405 is waiting to receive a message from the vehicle-mounted device in the next step S407, the message 250 is transmitted in step S109. When the message is returned to the terminal candidate (subterminal candidate 1) or the message 260 is returned to the subterminal candidate (subterminal candidate 1) in step S111, the message 250 or message 260 is received in step S407. In the next step S408, it is confirmed whether the received message is “response: permission to enter in-vehicle device group” or “response: not permitted to enter in-vehicle device group”, and “response: If “permit to enter in-vehicle device group” is received, the process proceeds to step S409 to promote the sub-terminal candidate (sub-terminal candidate 1) to a sub-terminal, but “response: enter in-vehicle device group”. When “not allowed” is received, the process ends as it is, so that the sub terminal candidate (sub terminal candidate 1) does not become a sub terminal.

  According to the communication system of this embodiment, the vehicle unit unique number included in the message 240 that is a response signal from the sub terminal candidate received by the reception unit 140 of the vehicle unit 100 is stored in the storage unit 110. If it matches the number 115, the sub-terminal candidate is controlled to be registered in the group, so that it is not necessary to use a plurality of antennas with narrow directivity as in the prior art 1, and the cost of the communication system can be reduced. In addition, using the short-range wireless function of the wireless communication terminal with short-range wireless function (mobile phone) and the short-range wireless function of the in-vehicle device 100, a plurality of wireless communication terminals with short-range wireless function (main terminal and sub-terminal candidates) ) Can be registered as a group. Furthermore, by forming this group, for example, “distribution (split account) calculation of highway toll payment” can be performed by the in-vehicle device 100.

  Further, according to the communication system of the present embodiment, only when the telephone number of the main terminal is registered in the sub terminal candidate's phone book, the sub terminal candidate can be promoted to the sub terminal and can form a group. Even if the in-vehicle device receives a message issued from an in-vehicle device in another group outside the vehicle or a message issued from a sub-terminal candidate in another group outside the vehicle, It is possible to recognize and register only the main terminal and sub terminal candidates that are registered in the phone book in the vehicle without misrecognizing the sub terminal candidates of the group. become.

[Second Embodiment]
FIG. 12 is a flowchart showing the terminal recognition control of the second embodiment performed by the in-vehicle device in the communication system of the present invention, and FIG. 13 shows the second embodiment of the second embodiment performed by the sub-terminal candidates in the communication system of the present invention. FIG. 14 is a flowchart showing terminal recognition control according to the second embodiment performed by another sub-terminal candidate that is already a sub-terminal in the communication system of the present invention.

  First, in step S121 of FIG. 12, the vehicle-mounted device 100 is turned on (turned on) simultaneously with the vehicle accessory (ACC) power turned on (turned on). Thereafter, in order to register the telephone number of the main terminal, when the telephone number of the main terminal is input to the in-vehicle device 100, main terminal registration (registration of the main terminal telephone number) is performed in step S122. In the next step S123, speed measurement is performed. This speed measurement is repeated until the vehicle speed exceeds a predetermined speed (for example, 20 km / h) and Step S124 becomes Yes. When the vehicle speed exceeds the predetermined speed (for example, 20 km / h), the process proceeds to Step S125. In step S125, as shown in FIG. 1, a message 220 composed of “request: enter in-vehicle device group”, “main terminal phone number”, and “in-vehicle device unique number” is used using short-range radio. To the sub terminal candidates 200S1 to 200S4.

  In response to the transmission of the message 220, the sub-terminal candidates (sub-terminal candidates 200S1 to 200S4; the sub-terminal candidate 1 in FIG. When the message 220 is received by the sub-terminal candidate 200S1), in the next step S412, it is confirmed whether or not “the telephone number of the main terminal” is registered in the telephone book of the own terminal. If registered, the process proceeds to step S413 to perform speed measurement, and if not registered, the process proceeds to step S416 to perform speed measurement. The speed measurement in step S413 is repeated until the vehicle speed exceeds a predetermined speed (for example, 20 km / h) and step S414 becomes Yes. When the vehicle speed exceeds the predetermined speed (for example, 20 km / h), the process proceeds to step S415. move on. In step S415, as shown in FIG. 15, a message 240 composed of “response: enter in-vehicle device group”, “sub-terminal candidate (sub-terminal candidate 1) telephone number”, and “in-vehicle device unique number” is displayed. A reply is sent to the vehicle-mounted device 100 using short-range radio. On the other hand, the speed measurement in step S416 is repeated until the vehicle speed exceeds a predetermined speed (for example, 20 km / h) and step S417 becomes Yes. When the vehicle speed exceeds the predetermined speed (for example, 20 km / h), the step is repeated. The process proceeds to S418. In step S418, from “response: phone number of main terminal candidate not registered in sub terminal phone book” and “phone number of sub terminal candidate (sub terminal candidate 1)” as illustrated in FIG. The message 270 is returned to the in-vehicle device 100 using the short-range radio.

  The in-vehicle device 100 that has transmitted the message 220 in step S125 waits to receive a message from the sub-terminal candidate in the next step S126, and therefore the message 240 is returned to the in-vehicle device 100 in step S415. When the message 270 is returned to the vehicle-mounted device 100 in step S418, the message 240 or message 270 is received in step S126. In the next step S127, the content of the received message is confirmed. If the received message is the message 240, the process proceeds to step S128. If the received message is the message 270, the process proceeds to step S133.

  In step S128, it is confirmed whether or not the “vehicle equipment unique number” in the received message 240 matches the vehicle equipment unique number assigned to the vehicle equipment 100. Here, if the “vehicle equipment unique number” in the received message 240 matches the vehicle equipment unique number assigned to the vehicle equipment 100, “response: enter group of vehicle equipment” in the received message 240. The in-vehicle device 100 performs sub-terminal registration to add the sub-terminal candidate as a sub-terminal to the group, and then performs “response” as illustrated in FIG. 11 in step S130. : A message 250 consisting of “permit to enter in-vehicle device group” is returned to the sub-terminal candidate (sub-terminal candidate 1) using the short-range radio. On the other hand, in step S128, if the “vehicle equipment unique number” in the received message 240 does not match the vehicle equipment unique number assigned to the vehicle equipment 100, “response: group of vehicle equipment” is received in the received message 240. After determining that “enter” is invalid and proceeding to step S131, the in-vehicle device 100 performs processing for refusing to add the sub-terminal candidate to the group, and then in step S132, as illustrated in FIG. A message 260 consisting of “response: not allowed to enter in-vehicle device group” is returned to the sub-terminal candidate (sub-terminal candidate 1) using the short-range radio.

  Since the sub terminal candidate (sub terminal candidate 1) that has transmitted the message 240 in step S415 is waiting to receive a message from the in-vehicle device in the next step S419, the message 250 is displayed in step S130. When the message is returned to the terminal candidate (subterminal candidate 1) or the message 260 is returned to the subterminal candidate (subterminal candidate 1) in step S132, the message 250 or message 260 is received in step S419. In the next step S420, it is confirmed whether the received message is “response: permission to enter in-vehicle device group” or “response: not allowed to enter in-vehicle device group”, and “response: If “permit to enter in-vehicle device group” is received, the process proceeds to step S421 to promote the sub-terminal candidate (sub-terminal candidate 1) to a sub-terminal, but “response: enter in-vehicle device group”. When “not allowed” is received, the process ends as it is, so that the sub terminal candidate (sub terminal candidate 1) does not become a sub terminal.

  In step S133, which proceeds from step S127 when the message 270 is received, "request: sub-terminal candidate telephone number inquiry" and "sub-terminal candidate (sub-terminal candidate 1) telephone number" as illustrated in FIG. Is transmitted to the sub-terminal using the short-range radio, and an inquiry is made as to whether or not the sub-terminal candidate is registered in the telephone book of the own terminal. In FIG. 16, all of sub-terminal candidate 2, sub-terminal candidate 3, and sub-terminal candidate 4 that are sub-terminal candidates other than the sub-terminal candidate that transmitted message 270 are already sub-terminals, and are added to the group Shows the case.

  In response to the transmission of this message 280, in step S431 of FIG. 14, the sub-terminals waiting to receive the message (sub-terminal 2 in which sub-terminal candidate 2 is promoted, sub-terminal 3 in which sub-terminal candidate 3 is promoted, When each of the sub-terminals 4) to which the sub-terminal candidate 4 has been promoted receives the message 280, in the next step S432, “the telephone number of the sub-terminal candidate (sub-terminal candidate 1)” is registered in the own phone book. Check if it exists. Here, if “the telephone number of the sub terminal candidate (sub terminal candidate 1)” is registered in the phone book of the own terminal, the process proceeds to step S433, and “response: already existing” as illustrated in FIG. If the message 290 consisting of “registration” is returned to the vehicle-mounted device 100 using short-range wireless communication, and the “phone number of the sub terminal candidate (sub terminal candidate 1)” is not registered in the phone book of the own terminal, Proceeding to step S434, a message 300 consisting of “response: unregistered” as illustrated in FIG. 17 is returned to the in-vehicle device 100 using the short-range radio.

  The in-vehicle device 100 that has transmitted the message 280 in step S133 waits to receive a message from the sub-terminal in the next step S134. Therefore, in step S433, the message 290 is returned to the in-vehicle device 100, or When the message 300 is returned to the in-vehicle device 100 in step S434, the message 290 or the message 300 is received in step S134. In the next step S135, it is confirmed whether or not the message 290 consisting of “response: already registered” has been received. Here, when at least one message 290 consisting of “response: registered” is received, the in-vehicle device 100 determines that the relevant sub terminal candidate is suitable for promotion to a sub terminal, and proceeds to step S136. After performing sub-terminal registration for adding the sub-terminal candidate to the group, in step S137, a message 250 consisting of “response: permission to enter in-vehicle device group” as illustrated in FIG. 18 is sent to the sub-terminal. A reply is sent to the candidate (sub-terminal candidate 1) using short-range radio. On the other hand, if no message 290 consisting of “response: already registered” is received in step S135, the in-vehicle device 100 determines that the sub-terminal candidate is not suitable for being promoted to a sub-terminal. After proceeding to step S138 and refusing to add the sub-terminal candidate to the group, in step S139, as shown in FIG. 18, “response: not allowed to enter in-vehicle device group”. Message 260 is sent back to the sub-terminal candidate (sub-terminal candidate 1) using near field radio.

  Since the sub terminal candidate (sub terminal candidate 1) that has transmitted the message 270 in step S418 is waiting to receive a message from the vehicle-mounted device in the next step S422, the message 250 is transmitted in step S137. When the message is returned to the terminal candidate (sub-terminal candidate 1) or the message 260 is returned to the sub-terminal candidate (sub-terminal candidate 1) in step S139, the message 250 or message 260 is received in step S422. In the next step S423, it is confirmed whether the received message is “response: permission to enter in-vehicle device group” or “response: not permitted to enter in-vehicle device group”, and “response: If the “permit to enter in-vehicle device group” is received, the process proceeds to step S424 to promote the sub-terminal candidate (sub-terminal candidate 1) to a sub-terminal, but “response: enter in-vehicle device group”. When “not allowed” is received, the process ends as it is, so that the sub terminal candidate (sub terminal candidate 1) does not become a sub terminal.

  According to the communication system of the present embodiment, the same operational effects as those of the communication system of the first embodiment can be obtained.

[Third Embodiment]
FIG. 19 is a flowchart showing the terminal recognition control of the third embodiment implemented by the vehicle-mounted device in the communication system of the present invention, and FIG. 20 shows the third embodiment implemented by the sub-terminal candidates in the communication system of the present invention. It is a flowchart which shows terminal recognition control. In addition, although the case where the link of the short-distance wireless function of the main terminal is disconnected is described below, the same terminal recognition control is performed even when the registration of the main terminal is artificially cancelled.

  In the vehicle-mounted device 100 that is powered on and continues the terminal recognition control of the first embodiment and the terminal recognition control of the second embodiment, the main terminal is a short-range wireless in step S141 of FIG. Is linked, and if linked, the process proceeds to step S142, and if not linked, the process proceeds to step S146. In step S142, it is monitored whether or not the sub-terminal is linked to the in-vehicle device 100 by short-range wireless communication. If linked, the process proceeds to step S143, and if not linked, the process proceeds to step S144 to be described later. The process proceeds to “Processing for Sub-Terminal with Short-range Wireless Link Broken” in the embodiment. In step S143, it is confirmed whether or not the new short-range wireless function terminal (mobile phone) is in the short-range wireless area, and the new short-range wireless function terminal (mobile phone) is in the short-range wireless area. In step S145, the process proceeds to "processing in step S103 and subsequent steps in FIG. 5", and if a new short-range wireless function-equipped terminal (mobile phone) is not in the short-range wireless area, the process ends (step S141). To return).

  In step S146, speed monitoring is started. In the next step S147, elapsed time monitoring is started. In the next step S148, it is monitored whether or not the main terminal is linked to the vehicle-mounted device 100 by short-range wireless. If linked, the process proceeds to step S149, and if not linked, the process proceeds to step S150. In step S149, which is performed when the link of the main terminal once broken is restored, the elapsed time is reset to zero. In step S150, it is confirmed whether or not the vehicle speed exceeds a predetermined speed (for example, 20 km / h). If the vehicle speed is less than the predetermined speed (for example, 20 km / h), the process proceeds to step S151 and the elapsed time is set to zero. After resetting, the process returns to step S148, and when the vehicle speed exceeds a predetermined speed (for example, 20 km / h), the process proceeds to step S152. In step S152, it is confirmed whether or not the elapsed time exceeds a predetermined time (for example, 10 seconds), and the process returns to step S148 until the elapsed time reaches the predetermined time (for example, 10 seconds). If it exceeds 10 seconds), the process proceeds to step S153. In step S153 that proceeds when the short-distance wireless link between the in-vehicle device 100 and the main terminal remains disconnected and the vehicle speed of 20 km / h or more continues for 10 seconds or more, the in-vehicle device 100 has the main terminal outside the vehicle. Alternatively, it is determined that the main terminal is turned off, and the main terminal is deleted from the group. In the next step S154, a message 310 consisting of “request: main terminal registration” as illustrated in FIG. 21 is transmitted to the sub-terminals (sub-terminal 1 to sub-terminal 4) using short-range radio.

  Since the sub-terminals (sub-terminal 1 to sub-terminal 4) are waiting to receive a message from the in-vehicle device in step S441 in FIG. 20, the message 310 is sub-terminal (sub-terminal 1 to sub-terminal) in step S154. When transmitted to 4), the message 310 is received in step S441. In the next step S442, the received message 310 including “request: main terminal registration” is notified to the user of each sub-terminal using at least one of “sound”, “light”, and “vibration”. Any one of the users of the sub-terminals having received this notification, in the next step S443, makes the telephone number of the sub-terminal the new “main terminal telephone number” as shown in FIG. Upon registration, the in-vehicle device 100 that has received the registration registers the telephone number of the sub terminal in the in-vehicle device 100 as “the telephone number of the main terminal” in step S155 of FIG. When the registration of the telephone number of the main terminal is completed, the in-vehicle device 100 starts a process for forming a group.

  In addition, when the power of the in-vehicle device 100 that has been performing the terminal recognition control of the first to third embodiments is turned off (off), “group registration immediately before the power is turned off (off)”. "Status" is stored in the in-vehicle device 100, and when the power of the in-vehicle device 100 is turned on (ON) next time, the stored "group registration status immediately before the power is turned off (OFF)" is stored. Referring to the main terminal that is under control immediately before the power of the in-vehicle device 100 is turned off (off), the in-vehicle device 100 can try to connect using the short-range radio, and the previous main terminal can be detected. If the previous main terminal is registered again in the main terminal, and the previous main terminal cannot be detected, steps S154 and S155 in FIG. 19 and steps S441 to S443 in FIG. 20 are performed. For example, if the sub-terminal requests “registration of a new main terminal”, for example, “the user of the main terminal that divides one of the two vehicles has two vehicles when stopping in the service area. It will be possible to deal with the case of “changing to the other side”.

  According to the communication system of the present embodiment, the same operational effects as those of the communication system of the first embodiment can be obtained.

If the link is established, the process proceeds to step S152. If the link is not established, the process proceeds to step S153, and the above-mentioned "Short-range wireless link after step S146 in FIG. The process proceeds to “Process for main terminal”. In step S152, it is monitored whether or not the sub-terminal is linked to the in-vehicle device 100 with the short-range wireless function. If linked, the process proceeds to step S154, and if not linked, the process proceeds to step S155. In step S154, it is confirmed whether or not the new short-range wireless function terminal (mobile phone) is in the short-range wireless area, and the new short-range wireless function terminal (mobile phone) is in the short-range wireless area. In step S156, the process proceeds to “processing in step S103 and subsequent steps in FIG. 5”. If a new short-range wireless function-equipped terminal (cellular phone) is not in the short-range wireless area, the process ends (step S151). To return).

  In step S155, speed monitoring is started. In the next step S157, elapsed time monitoring is started. In the next step S158, it is monitored whether or not the sub terminal is linked to the in-vehicle device 100 with the short-range wireless function. If linked, the process proceeds to step S159, and if not linked, the process proceeds to step S160. In step S159, which is performed when the link of the sub-terminal once disconnected is restored, the elapsed time is reset to zero. In step S160, it is confirmed whether or not the vehicle speed exceeds a predetermined speed (for example, 20 km / h). If the vehicle speed is less than the predetermined speed (for example, 20 km / h), the process proceeds to step S161 and the elapsed time is set to zero. After resetting, the process returns to step S158, and when the vehicle speed exceeds a predetermined speed (for example, 20 km / h), the process proceeds to step S162. In step S162, it is confirmed whether or not the elapsed time exceeds a predetermined time (for example, 10 seconds), and the process returns to step S158 until the elapsed time reaches the predetermined time (for example, 10 seconds). If it exceeds 10 seconds), the process proceeds to step S163. In step S163, which proceeds when the short-distance wireless link between the in-vehicle device 100 and the sub-terminal is disconnected and the vehicle speed of 20 km / h or more continues for 10 seconds or more, as illustrated in FIG. Then, it is determined whether the sub terminal is outside the vehicle or the sub terminal is turned off, and the sub terminal is deleted from the group.
