Description

The present invention relates to communication systems, control devices, vehicles, communication methods and programs.

With the development of wireless communication technology, terminal devices having various functions such as mobile phones have become widespread. In-vehicle systems installed in vehicles that are equipped with a communication function are also widespread. In general, a terminal device has a shorter product life cycle than an in-vehicle system, and the communication function of the terminal device may be superior. Therefore, conventionally, a communication system has been proposed in which a communication device installed in a vehicle and a terminal device owned by a user cooperate with each other.

For example, in Patent Document 1, each telephone in which a mobile phone telephone number is stored in a SIM (Subscriber Identity Module) card and a telephone number included in a mobile information read response signal transmitted from the mobile phone is stored in the SIM card. When any of the numbers is matched, the telephone function of the mobile phone corresponding to the telephone number included in the mobile information read response signal is stopped, and the telephone function is enabled by the telephone number of the compatible mobile phone. Have been described. This car phone device starts the cooperation operation with the user's mobile phone at the timing when the accessory switch of the vehicle is turned on, and cancels the cooperation operation at the timing when the accessory switch is turned off.

Japanese Unexamined Patent Publication No. 2004-193641

Wireless communication is performed between the terminal device brought in with the boarding of the user and the communication device installed in the vehicle using a short-range wireless communication method (for example, IEEE802.5.1, IEEE802.11). It is assumed that they work together. In this case, the communication device performs operations such as standby for cooperative operation and scanning. Therefore, if the cooperative operation is not performed only when necessary, the communication device wastes power for those operations. If the same control as that of the car phone device described in Patent Document 1 is performed, the cooperative operation can be performed only when necessary. However, in this method, the accessory switch is turned on even when the user gets on the vehicle. It is not possible to start the cooperative operation until.

A terminal device that can be connected using the second network is detected in the unit, and when a terminal device that can be connected using the second network exists, communication between the terminal device and the second network is started. When the communication function of the terminal device is used, when the terminal device is made to access the first network using the communication profile of the own system and there is no terminal device that can be connected using the second network. The communication unit is a communication system that allows the communication function of the communication unit to be used, and the communication unit accesses the first network using the communication profile of the own system .

(First Embodiment)
First, the first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic block diagram showing a configuration example of the communication system 1 according to the present embodiment.
The communication system 1 includes an in-vehicle system 10, a mobile phone 20, and a server device 30.

The in-vehicle system 10 is a group of devices installed in a vehicle, and includes a communication module 13 that provides a communication function using a predetermined public wireless communication system (for example, LTE (Long Term Evolution)). The in-vehicle system 10 functions as a communication system that mainly provides functions such as information provision and communication to a user who gets on a vehicle. "In-vehicle" of the in-vehicle system 10 means that it is suitable for use when it is installed in a vehicle, and it means that all or a part of the components of the in-vehicle system 10 are implemented when it is installed in a vehicle. It does not mean to limit. The vehicle on which the in-vehicle system 10 is installed is, for example, a four-wheeled vehicle, which has a space (vehicle compartment) on which a person can board, and has a door (doorway) that opens or closes the space with respect to the surroundings. The power source of the in-vehicle system 10 is electric power generated by an electric motor installed in the vehicle, electric power discharged from a secondary battery, or the like.

The in-vehicle system 10 detects the state of the door of the vehicle and determines whether or not the user is in the vehicle. Further, when it is determined that the user is in the vehicle, an operation of searching for a communication partner by a short-range wireless communication method (so-called scanning operation) is performed, and the short distance between the mobile phone 20 owned by the user and the in-vehicle system 10 is performed. Start communication by distance wireless communication method or the like. When it is determined that the in-vehicle system 10 and the mobile phone 20 are in a state of being able to communicate with each other, the in-vehicle system 10 starts a cooperative operation with the mobile phone 20. More specifically, the public wireless communication function of the vehicle-mounted system 10 is stopped, and the mobile phone 20 is used to transmit and receive information between the vehicle-mounted system 10 and other devices by using the communication between the vehicle-mounted system 10 and the mobile phone 20. Control to do through. When it is determined that the in-vehicle system 10 and the mobile phone 20 cannot communicate with each other, the in-vehicle system 10 ends the cooperation operation with the mobile phone 20. More specifically, the public wireless communication function of the in-vehicle system 10 that has been stopped is restarted, and information is transmitted / received between the in-vehicle system 10 and other devices by using the public wireless communication function of the in-vehicle system 10. Control. When the in-vehicle system 10 changes the operation state of the communication function of its own system, the in-vehicle system 10 may transmit the cooperation operation state information indicating whether or not the cooperation operation is performed to the server device 30. Hereinafter, the state in which this cooperation operation is performed is referred to as "coordination in progress", and the state in which this cooperation operation is not performed is referred to as "non-cooperation in progress".

The mobile phone 20 is a terminal device that provides a communication function using a predetermined public wireless communication method. The mobile phone 20 is, for example, a multifunctional mobile phone (including a so-called smartphone). When performing a cooperative operation with the in-vehicle system 10, the mobile phone 20 may switch the communication profile of its own unit to the communication profile of the in-vehicle system 10. When canceling the cooperation operation with the in-vehicle system 10, the mobile phone 20 may switch the communication profile of the in-vehicle system 10 to the communication profile of its own device. The communication profile is data used by the subscriber's terminal device for communication via a public wireless network. In the following description, the communication profile is simply referred to as a profile. The public wireless communication system used by the mobile phone 20 may be different from the public wireless communication system used by the communication module 13 of the in-vehicle system 10. For example, when the mobile phone 20 uses the method specified by LTE, the communication module 13 may use the method specified by IMT2000 (International Mobile Telecommunication 2000).

The server device 30 is a server device installed to support the functions of the in-vehicle system 10. The server device 30 is used, for example, for complementing the functions of the in-vehicle system 10, updating (version upgrade), maintenance (maintenance), user management, and the like. The user list is stored in the server device 30 in advance. The user list is data including system identification information and terminal identification information, and is configured by associating the system identification information with the terminal identification information. The terminal identification information is identification information indicating each mobile phone 20. The system identification information is identification information indicating each in-vehicle system 10. As the identification information, a network address such as an IP (Internet Protocol) address may be used, or a physical address such as a device-specific MAC (Media Access Control) address may be used. For example, the server device 30 acquires a set of system identification information and terminal identification information in the user registration process of the in-vehicle system 10. When the server device 30 actively tries to transmit (push) information to the vehicle-mounted system 10, if the vehicle-mounted system 10 and the mobile phone 20 are not linked, the server device 30 is added to the user list. The information is directly transmitted to the in-vehicle system 10 with reference to the included system identification information. When the in-vehicle system 10 and the mobile phone 20 are in cooperation with each other, the server device 30 refers to the terminal identification information and transmits the information to the mobile phone 20. In the latter case, the mobile phone 20 transfers the received information to the in-vehicle system 10 by using the function of the cooperative operation.

The server device 30 controls the communication function of the vehicle-mounted system 10 and the communication function of the mobile phone 20 associated with the vehicle-mounted system 10 in response to the reception of the cooperative operation state information from the vehicle-mounted system 10. The server device 30 refers to the user list stored in advance and selects the terminal identification information associated with the system identification information added to the cooperation operation state information. Therefore, the mobile phone 20 is specified as the switching destination of the communication function of the in-vehicle system 10. When the cooperation operation status information indicates that the cooperation is in progress, the server device 30 transmits a communication function stop request (communication module OFF request) indicating the stop of the communication function to the in-vehicle system 10. The in-vehicle system 10 stops the communication function of its own system in response to the reception of the communication function stop request from the server device 30.

Further, the server device 30 may transmit a profile switching request indicating switching to the profile of the in-vehicle system 10 to the mobile phone 20. Identification information for specifying the profile of the in-vehicle system 10 or the switching destination thereof, such as terminal identification information, may be added to the profile switching request. When the mobile phone 20 receives the profile switching request from the server device 30, the mobile phone 20 invalidates the preset profile of the own device and switches the valid profile to the profile of the in-vehicle system 10. Here, the mobile phone 20 specifies the in-vehicle system 10 indicated by the terminal identification information added to the profile switching request or the profile indicated by the profile identification information as the switching destination.

When the server device 30 receives the cooperation operation status information indicating that the in-vehicle system is not linked from the in-vehicle system 10 via the mobile phone 20, the server device 30 issues a communication function start request (communication module ON request) indicating the start of the communication function. It may be transmitted to 10 via the mobile phone 20. The in-vehicle system 10 cancels the use of the communication function of the mobile phone 20 and starts the public wireless communication function of its own system in response to the reception of the communication function start request from the server device 30. At this time, the server device 30 may send a profile switching request indicating switching to the profile of the mobile phone 20 to the mobile phone 20. When the mobile phone 20 receives the profile switching request from the server device 30, the mobile phone 20 invalidates the profile of the vehicle-mounted system 10 and switches the valid profile to the profile of the mobile phone 20.
The server device 30 may transmit map information indicating the positions of roads, buildings, etc., topographical distribution, and the like to the in-vehicle system 10. Map information is used, for example, for route guidance.

Next, the configuration of the in-vehicle system 10 according to the present embodiment will be described.
The in-vehicle system 10 includes a control unit 11, a sensor 12, a communication module 13, an I / F unit 14, a storage unit 15, and a navigation unit 16. The control unit 11, the sensor 12, the communication module 13, the I / F (interface) unit 14, the storage unit 15, and the navigation unit 16 are connected to each other so that various data can be input and output. For connection, a signal line or radio such as CAN (Control Area Network) is used.

The control unit 11 controls the functions of the in-vehicle system 10. The control unit 11 includes, for example, one or more control devices such as a CPU (Central Processing Unit). The control unit 11 realizes various functions by executing the process instructed by the instruction described in the predetermined program. The control unit 11 can be realized as, for example, a control device (ECU: Electronic Control Unit) that connects to a destination device using a communication module 13 and transmits / receives various data such as voice data to control a communication function.

The control unit 11 executes the boarding state determination process. In the boarding state determination process, the control unit 11 determines the state of each door installed in the vehicle by using the sensing signal input from the sensor 12. The sensing signal is, for example, a signal indicating whether or not the doorway is opened as a state of the doorway installed in the vehicle. Vehicles are generally equipped with multiple doors. When the control unit 11 determines that at least one of the doors has been opened, the control unit 11 determines that the boarding state may have changed, and performs a connection confirmation process in order to start communication with the mobile phone 20 to be linked. I do. Since the connection confirmation process is performed at this timing, the cooperative operation can be started promptly without performing an extra scan operation.

The connection confirmation process is a process for confirming whether or not a terminal device (including a mobile phone 20) that is a candidate for cooperation destination can be connected via a predetermined second network (for example, a short-range wireless network) (hereinafter referred to as a connection confirmation process). , Connection confirmation process), and includes, for example, a process of searching for a communication partner in the IEEE802.5.1 communication method, that is, an operation such as so-called scanning. Therefore, in the storage unit 15, linked terminal data including terminal identification information indicating the linked terminal device is set in advance.
At this time, in the terminal device that is a candidate for the cooperation destination, the predetermined second network is not always in a usable state. Therefore, the control unit 11 is a terminal that is a candidate for a cooperation destination via the first network (for example, a public wireless network) before performing a process of confirming whether or not the connection is possible via the second network. A process may be performed to send a request to enable the second network to the device.

When starting the connection confirmation process, the control unit 11 outputs a connection confirmation request to the I / F unit 14. The connection confirmation request is a signal for instructing confirmation of whether or not the terminal device (including the mobile phone 20) that is a candidate for the cooperation destination can be connected via the second network. The control unit 11 inputs a connection status notification from the I / F unit 14 as a response to the connection confirmation request. The connection status notification is a response signal indicating whether or not the connection with the terminal device of the transmission source is possible.
When the terminal identification information of the terminal device that is the source of the connection status notification matches any of the terminal identification information included in the cooperation terminal data, the control unit 11 determines that cooperation with the terminal device is permitted.

After that, the control unit 11 determines that the cooperative operation state of the mobile phone 20, which is the terminal device determined to be permitted, is being linked. When the terminal device determined to be permitted does not exist, the control unit 11 determines that the cooperative operation state of the terminal device is not linked.

The control unit 11 performs the cooperation start processing when the cooperation operation state of the determined terminal device changes from non-cooperation to during cooperation. In the cooperation start processing, the control unit 11 transmits a cooperation operation state notification indicating the determined cooperation operation state to the server device 30 via the communication module 13. The control unit 11 receives a communication function stop request from the server device 30 via the communication module 13 as a response to the cooperation operation status notification. At this time, the control unit 11 outputs a communication function stop request to the communication module 13 to stop the communication function in the communication module 13. After that, the control unit 11 starts a cooperative operation with the mobile phone 20.

In the cooperative operation, the control unit 11 outputs the transmission data related to the communication function of the in-vehicle system 10 to the mobile phone 20 via the I / F unit 14 and causes the mobile phone 20 to transmit the transmission data. The control unit 11 causes the mobile phone 20 to receive the received data related to the communication function, and inputs the received data from the mobile phone 20 via the I / F unit 14.

When the linked operation state of the terminal device, which is determined according to the input of the sense signal, changes from linked to non-linked, the cooperation end process is performed. In the cooperation end processing, the control unit 11 outputs a communication function start request to the communication module 13, restarts the communication function, and then transmits / receives information to / from other devices in the vehicle instead of the I / F unit 14. It is performed by using the public wireless communication function of the system 10. More specifically, the control unit 11 causes the communication module 13 to transmit the transmission data related to the communication function, and causes the communication module 13 to receive the reception signal. Further, a cooperation operation state notification indicating the determined cooperation operation state is transmitted to the server device 30 via the communication module 13.

The sensor 12 may be configured to include a door sensor that senses the state of a door installed in the vehicle. The door sensor is configured to include, for example, a pressure sensor and is installed for each door. The pressure sensor detects the pressure applied to the portion where the open end of the door contacts the vehicle body. The sensor 12 determines, for example, whether the detected pressure is open or closed as the state of each door based on whether or not the detected pressure is larger than the threshold value of the predetermined pressure, and detects the state of each door that has been determined. The signal is output to the control unit 11.

The communication module 13 provides a communication function with other devices via the first network. The first network is, for example, a public wireless network realized by using LTE, which is a typical wireless communication method.
The communication module 13 stops the communication function when a communication function stop request is input from the control unit 11. On the other hand, when the communication function start request is input from the control unit 11, the communication module 13 starts the communication function by the own machine. In order to start the communication function, the communication module 13 reads the profile of the own system stored in the storage unit 15 and accesses the first network using the read profile.

When the cooperative operation is not performed, the communication module 13 transmits the transmission data input from the control unit 11 to the destination device via the first network. Then, the communication module 13 outputs the received data received from the destination device via the first network to the control unit 11.

The I / F unit 14 provides an input / output function with another device via a second network. The second network is, for example, a short-range wireless communication network realized by using the method specified in IEEE802.5.1, which is a typical short-range wireless communication method.
In order to realize the input / output function, the I / F unit 14 performs a connection confirmation process. The I / F unit 14 detects a device determined to be connectable in the connection confirmation process as an input / output destination device. When the connection confirmation request is input from the control unit 11, the I / F unit 14 performs a connection confirmation process with the mobile phone 20 via the second network. In the connection confirmation process, the I / F unit 14 may transmit the connection confirmation signal to the I / F unit 23 of the mobile phone 20 via the second network. The I / F unit 14 determines that the connection is possible when the connection response signal is received within a predetermined time from the output of the connection confirmation signal, and determines that the connection is not possible when the connection response signal is not received within the predetermined time. The I / F unit 14 outputs a connection status notification indicating whether or not the connection is possible to the control unit 11 as a response to the connection confirmation request. Further, the I / F unit 14 transmits a confirmation response signal indicating reception of the connection response signal to the I / F unit 23 of the mobile phone 20. The connection verification process consumes a lot of power and should be performed when it is needed and should not be performed when it is not needed. As described above, by starting the connection confirmation process when the connection confirmation request is received, it is possible to suppress an increase in power consumption.
The following control signals can be used as the connection confirmation signal and the connection response signal, for example. When the connection confirmation signal is the "inquiry" specified in IEEE802.5.1, the connection response signal may be a response to the "inquiry". Further, the connection response signal may be an advertising packet specified in IEEE802.5.1 Version 4.0. When the connection confirmation signal is the specified scan request of IEEE802.5.1 version 4.0, the connection response signal may be a scan response. Further, the connection response signal may be a beacon specified in 802.11. When the connection confirmation signal is the probe request specified in 802.11, the connection response signal may be the probe response.

When the operation in cooperation with the mobile phone 20 is performed, the I / F unit 14 transmits the transmission data input from the control unit 11 to the mobile phone 20 via the second network, and the mobile phone 20 sends the transmission data. The transmission data is transmitted to the destination device via the first network. Further, the mobile phone 20 receives the received data from the remote party device via the first network, and the I / F unit 14 receives the received data from the mobile phone 20 via the second network, and the received received data. Is output to the control unit 11.

The storage unit 15 stores data used for processing by the vehicle-mounted system 10 and data generated by the vehicle-mounted system 10. The storage unit 15 includes an HDD (Hard Disk Drive), a flash memory, an EEPROM (Electrically Erasable Programmable Read Only Memory), a ROM (Read Only Memory), a ROM (Read Only Memory), or a RAM (Random Access) medium. It is composed. The profile is stored in a part of the storage unit 15.
The storage medium in which the profile is stored is, for example, the SIM (Subscriber Identity Module) card shown in FIG. The SIM card is removable, and profile 1 is stored in advance as a profile of the in-vehicle system 10. The profile stored on the SIM card is generally immutable.

Generally, the profile includes terminal identification information for identifying individual communication devices (for example, in-vehicle system 10, mobile phone 20) and subscriber identification information for identifying individual subscribers (for example, subscriber number). Is included. When the communication device is connected to a public wireless network such as the first network, the terminal identification information and the subscriber identification information are combined with the subscriber information management device (for example, HSS: Home Subscriber Server, not shown) that constitutes the network. Send to. The subscriber information management device holds subscriber data including a set of terminal identification information and subscriber identification information for each contract with the subscriber. That is, the subscriber data is configured to include a profile for each contract. The subscriber information management device determines whether or not there is a set of the terminal identification information and the subscriber identification information included in the subscriber data in which the terminal identification information and the subscriber identification information received from the communication device match each other. As a result, it is determined whether or not the access from the communication device is an access from a legitimate subscriber or a terminal device. When there is a matching set, the subscriber information management device allows the source communication device to connect to the network. Then, the communication device indicated by the transmitted terminal identification information is recognized as a destination device or a candidate thereof from another communication device connected to the network. If there is no matching set, the subscriber information management device refuses to connect to the network from the source communication device. The above-mentioned "access (or communication) to a network using a profile" means to request permission for connection using the profile and then try or execute communication via the network.

Returning to FIG. 1, the navigation unit 16 guides the position where the vehicle is traveling and the traveling route. The navigation unit 16 acquires the current position information indicating the position of the vehicle at the present time and the destination information indicating the position of the destination. The navigation unit 16 has, for example, a GPS (Global Positioning System) function and acquires current position information. The navigation unit 16 may acquire the destination information from the operation input or the voice input, perform a predetermined route search process with reference to the map information, and acquire the route information from the current position to the destination. The navigation unit 16 displays guidance information obtained by superimposing current position information, destination information, and route information on map information.

Next, the configuration of the mobile phone 20 according to the present embodiment will be described.
The mobile phone 20 includes a control unit 21, a communication unit 22, an I / F unit 23, and a storage unit 24.
The control unit 21 controls the function of the mobile phone 20. The control unit 21 includes one or more control devices such as a CPU, for example. The control unit 21 realizes its function by executing the process instructed by the instruction described in the predetermined program. The control unit 11 uses, for example, the communication unit 22 to connect to the destination device and transmits / receives various data such as voice data to realize a communication function. Further, the control unit 21 executes the communication control process.

In the communication control process, the control unit 21 determines whether or not to cooperate with the in-vehicle system 10. The control unit 21 determines that cooperation is possible when the connection status notification input from the I / F unit 23 indicates that connection is possible. At other times, the control unit 21 determines whether or not the cooperation is established.

When the control unit 21 determines that the cooperation is possible, when the server device 30 receives the profile switching request from the server device 30 to the in-vehicle system 10 via the communication unit 22, the control unit 21 selects the profile of its own unit used for accessing the first network. Invalidate. At this time, the control unit 21 switches to the profile of the vehicle-mounted system 10 among the profiles stored in the storage unit 24 as an effective profile, and notifies the communication unit 22 of the switched profile. After that, the control unit 21 transmits a switching completion notification indicating the completion of switching of the communication function to the server device 30 via the communication unit 22. When it is determined whether or not the cooperation is established, the control unit 21 does not switch the profile regardless of whether or not the profile switching request is received.

When the control unit 21 receives the profile switching request from the server device 30 to its own device via the communication unit 22, the control unit 21 invalidates the profile of the vehicle-mounted system 10 used for accessing the first network. At this time, the control unit 21 switches to the profile of its own machine among the profiles stored in the storage unit 24 as an effective profile, and notifies the communication unit 22 of the switched profile. After that, the control unit 21 transmits a switching completion notification indicating the completion of profile switching to the server device 30 via the communication unit 22.

The communication unit 22 provides a communication function with other devices via the first network. Unless otherwise specified, the communication unit 22 accesses the first network using the profile of its own machine. However, when the profile is notified from the control unit 21, the first network is accessed using the notified profile.

When providing the communication function by the own device, the communication unit 22 transmits the transmission data input from the control unit 21 to the connected destination device via the first network, and the destination device sends the transmission data to the first network. The received data received via the above is output to the control unit 21.
When executing the cooperative operation with the in-vehicle system 10, the communication unit 22 connects the first network to the destination device to which the transmission data input from the control unit 21 from the in-vehicle system 10 via the I / F unit 23 is connected. The received data transmitted via the remote device and received from the destination device via the first network is output to the in-vehicle system 10 via the control unit 21 and the I / F unit 23.

The I / F unit 23 provides an input / output function with another device via a second network.
When the I / F unit 23 receives the connection confirmation signal from the I / F unit 14 during the connection confirmation process with the I / F unit 14 of the in-vehicle system 10, the I / F unit 23 receives the connection response signal as the response from the I / F unit 14. Send to. After transmitting the connection response signal, the I / F unit 23 determines that the connection is possible when the confirmation response signal is received from the I / F unit 14 within a predetermined time, and the connection is not received when the confirmation response signal is not received within the predetermined time. Is determined. The I / F unit 23 outputs a connection status notification indicating whether or not the connection with the I / F unit 14 is possible to the control unit 21.

The storage unit 24 stores data used for processing in the control unit 21 and data generated by the control unit 21. The storage unit 24 includes one or more storage media such as an HDD, a flash memory, an EEPROM, a ROM, or a RAM. A profile is stored in a part of the storage unit 24. The storage medium in which the profile is stored is, for example, the eSIM (embedded Subscriber Identity Module) shown in FIG. eSIM is also called eUICC (embedded Universal Integrated Circuit Card). The eUICC is a storage medium that has a removable type and a non-detachable type, the stored profile itself can be updated, and the effectiveness of each stored profile is variable. In the example shown in FIG. 2, the profile 1 described above and the profile 2 as the profile of the mobile phone 20 are stored in the eSIM. When the operation in cooperation with the in-vehicle system 10 is performed, the profile 1 becomes valid and the profile 2 becomes invalid. If the cooperation operation with the in-vehicle system 10 is not performed, the profile 2 becomes valid and the profile 1 becomes invalid.

(Collaboration operation start processing)
Next, the cooperative operation start processing according to the present embodiment will be described.
FIG. 4 is a sequence diagram showing an example of the cooperative operation start processing according to the present embodiment.
(Step S101) The sensor 12 of the vehicle-mounted system 10 senses the state of the door installed in the vehicle, and outputs a sensing signal indicating the sensed door state to the communication module 13. After that, the process proceeds to step S102.
(Step S102) When the control unit 11 of the vehicle-mounted system 10 determines that any of the doors installed in the vehicle has been opened based on the detection signal input from the sensor 12, the control unit 11 makes a connection confirmation request to the I / F unit. Output to 14. The I / F unit 14 of the in-vehicle system performs a connection confirmation process via the second network in response to an input of a connection confirmation request from the control unit 11. Here, the I / F unit 14 may transmit the connection confirmation signal to the mobile phone 20 via the second network. The I / F unit 14 receives the connection response signal transmitted by the I / F unit 23 of the mobile phone 20. The connection response signal may be transmitted as a response to the connection confirmation signal transmitted by the I / F unit 14. When the I / F unit 14 receives the connection response signal within a predetermined time from the input of the connection confirmation request, the I / F unit 14 performs a communication connection process with the I / F unit 23 of the mobile phone 20 and causes the control unit 11 to perform a second communication connection process. Output an acknowledgment signal. When the confirmation response signal is input from the I / F unit 14 within a predetermined time from the output of the connection confirmation request, the control unit 11 determines that the mobile phone 20 is connected. After that, the process proceeds to step S103.

(Step S103) When the connection status notification indicating connection is input from the communication module 13, the control unit 11 of the vehicle-mounted system 10 determines that the cooperation operation state of the mobile phone 20 is being linked. After that, the process proceeds to step S104.
(Step S104) The control unit 11 of the in-vehicle system 10 transmits a cooperation operation status notification indicating that cooperation is in progress to the server device 30 via the communication module 13. After that, the process proceeds to step S105.

(Step S105) When the cooperation operation status notification received from the in-vehicle system 10 indicates that the cooperation is in progress, the server device 30 refers to the user list as terminal identification information corresponding to the system identification information added to the cooperation operation status notification. , Identify the terminal identification information of the mobile phone 20. The server device 30 transmits a communication function stop request (communication module OFF request) to the in-vehicle system 10. The control unit 11 of the in-vehicle system 10 receives a communication function stop request from the server device 30 via the communication module 13. After that, the process proceeds to step S106.
(Step S106) The server device 30 requests the mobile phone 20 related to the specified terminal identification information to start the cooperation operation with the in-vehicle system 10. The server device 30 may transmit a profile switching request to the mobile phone 20. When the control unit 21 of the mobile phone 20 receives the profile switching request and is in the state of being connected to the in-vehicle system 10 in the second network, the control unit 21 gives an instruction in the profile switching notification among the profiles stored in the storage unit 24. You may switch to the profile of the in-vehicle system 10 to be used. After that, the process proceeds to step S107.

(Step S107) The in-vehicle system 10 and the mobile phone 20 start a cooperative operation. After that, the process shown in FIG. 4 is terminated.

(Processing order)
The process of FIG. 4 takes as an example the case where the process of step S106 is started after the process of step S105, but if it is after step S104, it may be started before step S105. good.

(Judgment of boarding status)
Next, an example of determining the boarding state of the vehicle will be described. In order to determine the boarding state, an example is taken in which the sensor 12 includes a door sensor that detects the state of each door, but the present invention is not limited to this. The sensor 12 may further include a weight sensor that detects the weight applied to each seat provided in the vehicle. The control unit 11 observes the duration of the state in which the amount of change in weight from the time of detecting the opening of the door is larger than the threshold value of the amount of change (for example, 20 to 30 kg). The control unit 11 determines that the terminal device may be boarded when the duration is longer than the predetermined duration (for example, 5 to 10 seconds), and when it is less than or equal to the predetermined duration, it is determined that the terminal device has not boarded. You may judge.

Further, the control unit 11 may include a so-called keyless entry system. The keyless entry system locks or unlocks the vehicle door based on a signal transmitted from a remote controller (electronic key). When the remote controller receives a radio beacon (beacon) transmitted from the keyless entry system at predetermined time (for example, 5 seconds) intervals, the remote controller transmits a response signal which is the response. When the duration of receiving the response signal from the remote controller is longer than the predetermined duration (for example, 10 seconds) from the time when the door opening is detected, the control unit 11 determines that there is a possibility of boarding, and determines that there is a possibility of boarding. When it is less than or equal to the duration, it may be determined that the passenger has not boarded.
Then, when determining that there is a possibility of boarding, the control unit 11 performs a connection confirmation process and determines whether the boarding state is boarding or not based on the determined connection availability.

(Priority)
In the above, the case where the terminal device of the cooperation destination is mainly one mobile phone 20 is taken as an example, but the number of candidate terminal devices to be linked may be a plurality of units.
Therefore, in step S102, when the control unit 11 of the in-vehicle system 10 determines that any of the doors installed in the vehicle has been opened, if the connection confirmation process is performed, it is determined that the plurality of terminal devices can be connected. There are times. Therefore, the control unit 11 may determine the terminal device having the highest priority among the terminal devices determined to be connectable among the priorities set in advance among the plurality of terminal devices as the terminal device to be linked. Then, the control unit 11 adds the terminal identification information of the defined terminal device to the cooperative operation status notification and transmits it to the server device 30.
When specifying the priority of each terminal device, the control unit 11 may refer to the linked terminal data stored in the storage unit 15. The linked terminal data is configured so that the system identification information is associated with the terminal identification information of the terminal devices that are candidates for a plurality of linked destinations, and the priority order of each candidate is shown. The priority order does not have to be explicitly described in the linked terminal data, and may be specified in the description order of the terminal identification information.

The server device 30 may perform the process of specifying the cooperation destination terminal device from the plurality of terminal devices instead of the control unit 11 of the in-vehicle system 10. As a premise, the control unit 11 adds the terminal identification information of the plurality of terminal devices to the cooperative operation status notification and transmits the terminal identification information to the server device 30. The server device 30 stores, for example, a user list in which system identification information is associated with candidate terminal identification information of a plurality of cooperation destinations and is configured to indicate the priority of each candidate.
The server device 30 refers to the user list, specifies the priority of each terminal device indicated by the terminal identification information added to the linked operation status notification, and selects the terminal device having the highest specified priority as the linked terminal. Identify as a device. Then, the server device 30 transmits a profile switching request to the specified terminal device.

In the above, the priority among a plurality of terminal devices is taken as an example, but it may be applied to the priority among a plurality of profiles. The profile specifies the terminal device and the first network used for communication by the terminal device or its usage conditions (for example, bandwidth, time zone, time, fee structure, etc.). Therefore, even one terminal device may have a plurality of profiles in which usage conditions are independently defined.

When a plurality of profiles are set as profiles of the in-vehicle system 10 in the storage unit 24 of the mobile phone 20, the control unit 21 defines the profile having the highest priority among the plurality of profiles as a valid profile. You may. The control unit 21 specifies the priority of each profile, for example, by the priority or the description order described in association with the profile in the storage unit 24.

Further, when the control unit 11 specifies the priority of each terminal device or profile, the control unit 11 may determine the priority based on other information instead of the priority or the description order described in advance. For example, the control unit 11 may count the frequency of use used for operation cooperation for each terminal device or profile, and set a priority so that the higher the frequency of use counted, the higher the frequency of use. As a result, the more frequently used terminal devices or profiles are used for operation cooperation.

The control unit 11 may time the elapsed time from the time of the last use for each terminal device or profile, and set a priority so that the shorter the time elapsed time is, the higher the time elapsed. Therefore, the terminal device or profile used most recently is preferentially used for operation cooperation.
The control unit 11 may specify the bandwidth which is the usage condition of the network described in the profile, and set the priority so that the wider the specified bandwidth is, the higher the bandwidth is. Therefore, priority is given to the use of profiles related to networks with wide bandwidth.
The control unit 11 may specify the charge system which is the usage condition of the network described in the profile, and set the priority so that the lower the charge calculated by the specified charge system, the higher the charge system. As a result, priority is given to the use of profiles related to networks with low charges. More specifically, the control unit 11 prioritizes the profile whose specified charge system is pay-as-you-go so that it is higher than the profile whose charge system is flat-rate, and for the profile whose charge system is pay-as-you-go. , The lower the pay-as-you-go unit price, the higher the priority may be set. As the pay-as-you-go unit price, for example, frequency (number of times), usage time, communication amount, and the like can be applied.

The server device 30 may also adopt the same method as the control unit 11 described above to determine the priority order for each terminal device or profile. The control unit 21 of the mobile phone 20 may also determine the priority order for each profile by using the same method as the control unit 11 described above.

As described above, the control unit 11 of the in-vehicle system 10 according to the present embodiment determines the cooperative operation state of the mobile phone 20 in the vehicle based on the change in the boarding state of the user in the vehicle detected by the sensor 12. .. When the control unit 11 determines that the cooperation operation state is in cooperation, the control unit 11 stops the communication function of the communication module 13 and enables the communication function of the mobile phone 20 to be used.
With this configuration, the user who owns the mobile phone 20 can have the in-vehicle system 10 use the communication function of the mobile phone 20 instead of the communication function of the communication module 13 when boarding the vehicle. Therefore, the cooperation operation with the communication module 13 is possible without the user performing the operation of the accessory switch or any other operation. In addition, since it is possible to reduce operations that consume a large amount of power, such as unnecessary standby and scanning, it is possible to reduce power consumption.

Further, the control unit 11 determines the cooperative operation state of the mobile phone 20 according to whether or not the communication module 13 and the mobile phone 20 can be connected.
With this configuration, it is possible to determine the possession of the mobile phone 20 of the boarding user and the presence / absence of the communication function of the mobile phone 20. Since the cooperative operation can be established more reliably, the power consumption can be further reduced.

Further, when it is determined that the mobile phone 20 is in cooperation, the control unit 11 notifies the server device 30 of the cooperation operation state, and when receiving a communication function stop request from the server device 30, the control unit 11 performs the communication function of the communication module 13. Stop.
With this configuration, the server device 30 can control the communication function of the communication module 13 according to the cooperative operation state of the mobile phone 20 in the in-vehicle system 10. Therefore, the server device 30 can manage the cooperative operation of the communication functions in the individual in-vehicle systems 10.

Further, when using the communication function of the mobile phone 20, the control unit 11 causes the mobile phone 20 to access the network using the communication profile of the communication module 13 of the in-vehicle system 10.
With this configuration, the network can be used in a form according to the contract related to the in-vehicle system 10 of the cooperation source. Further, communication with the in-vehicle system 10 as a communication partner can be realized by using the communication function of the mobile phone 20 without being aware of the mobile phone 20 from the device of the other party.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. The same components as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be incorporated. In the following description, the differences from the above-described embodiment will be mainly described.
The hardware configuration of the communication system 1 according to the present embodiment is the same as the hardware configuration of the communication system 1 according to the first embodiment. However, this embodiment differs from the first embodiment in the following points.

In the first embodiment, the server device 30 identifies whether or not the in-vehicle system 10 and the mobile phone 20 are in cooperation with each other. On the other hand, in the present embodiment, the server device 30 does not identify whether or not the in-vehicle system 10 and the mobile phone 20 are in cooperation with each other.
In the first embodiment, one of the reasons why the server device 30 identifies whether the in-vehicle system 10 and the mobile phone 20 are in cooperation with each other is that the server device 30 actively sends information to the in-vehicle system 10. This is to send (push). For example, when the in-vehicle system 10 and the mobile phone 20 are not linked, the server device 30 directly transmits information to the in-vehicle system 10 with reference to the system identification information, and when the in-vehicle system 10 is in cooperation, the server device 30 transmits the information directly to the in-vehicle system 10. Information is transmitted to the mobile phone 20 with reference to the terminal identification information. The mobile phone 20 transfers the information received from the server device 30 to the in-vehicle system 10 by using the function of the cooperative operation.

On the other hand, in the present embodiment, in order to enable the server device 30 to actively transmit (push) information to the in-vehicle system 10, the following operations are performed. First, when the in-vehicle system 10 and the mobile phone 20 are not linked, the in-vehicle system 10 periodically sends a connection request signal to the server device 30 with the system identification information of the in-vehicle system 10 via the first network. To send. When the in-vehicle system 10 and the mobile phone 20 are linked, the mobile phone 20 periodically transmits a connection request signal to which the system identification information of the in-vehicle system 10 is added to the server device 30 via the first network. do. In either case, the server device 30 does not immediately respond to the received connection request signal, but suspends it, and stores the latest received connection request signal in association with the system identification information of the vehicle-mounted system 10.

When the server device 30 actively transmits (pushes) information to the vehicle-mounted system 10, it transmits (pushes) a connection response signal to a connection request signal stored in association with the system identification information of the vehicle-mounted system 10. ) Send after adding the information you tried.
When the in-vehicle system 10 and the mobile phone 20 are not linked, the in-vehicle system 10 directly receives the information transmitted by the server device 30 as a part of the connection response signal to the connection request signal transmitted by itself. .. When the in-vehicle system 10 and the mobile phone 20 are linked, the mobile phone 20 receives the information transmitted by the server device 30 as a part of the connection response signal to the connection request signal transmitted by itself. The mobile phone 20 transfers the information received from the server device 30 to the in-vehicle system 10 by using the function of the cooperative operation. With such a mechanism, the server device 30 can transmit (push) information to the in-vehicle system 10 without recognizing whether or not the in-vehicle system 10 and the mobile phone 20 are in cooperation with each other.
Therefore, in the present embodiment, it is not necessary to explicitly notify the server device 30 from the in-vehicle system 10 or the mobile phone 20 that the cooperative operation has started or ended.

Next, the cooperative operation start processing according to the present embodiment will be described.
FIG. 5 is a sequence diagram showing an example of the cooperative operation start processing according to the present embodiment.
The process shown in FIG. 5 includes steps S101-S103, S107, and S201-S205. The in-vehicle system 10 performs the processes of steps S201 and S202 before the process of step S101.

(Step S201) The vehicle-mounted system 10 adds the system identification information of the vehicle-mounted system 10 to the connection request signal, and transmits the connection request signal to which the information is added to the server device 30 via the first network. After that, the process proceeds to step S202.
(Step S202) The server device 30 stores the connection request signal received from the vehicle-mounted system 10 in association with the system identification information added to the connection request signal. Further, when actively transmitting (pushing) information to the in-vehicle system 10, the server device 30 adds the information to be transmitted (pushed) as a response to the connection request signal received from the in-vehicle system 10. Then, the connection response signal is transmitted to the in-vehicle system 10.
When the in-vehicle system 10 receives the connection response signal from the server device 30, the in-vehicle system 10 takes out the information added to the connection response signal by the server device 30.

The processing of steps S201 and S202 does not necessarily have to be performed immediately before the processing of step S101. The trigger for starting the process of step S201 may be a part of a separate process whose main purpose is not the cooperative operation. The trigger may be, for example, a request for connection to the server device at the time of starting or operating the navigation unit 16.
In the communication between the communication module 13 and the server device 30 in steps S201 and S202, for example, TCP / IP (Transmission Control Protocol / Internet Protocol), HTTP (HyperText Transfer Protocol), or the like can be used as the communication protocol. be.

In the example shown in FIG. 5, after the control unit 11 of the vehicle-mounted system 10 determines in step S103 that the cooperative operation state of the mobile phone 20 is being linked, the process proceeds to step S203.
In step S203, the in-vehicle system 10 transmits a cooperation operation start request to the mobile phone 20. At this time, the vehicle-mounted system 10 may transmit a profile switching request to the profile of the vehicle-mounted system 10 to the mobile phone 20. When the control unit 21 of the mobile phone 20 receives the profile switching request, the control unit 21 may switch to the profile of the in-vehicle system 10 instructed by the profile switching notification among the profiles stored in the storage unit 24. After that, the process proceeds to step S107.

(Step S107) The in-vehicle system 10 and the mobile phone 20 start a cooperative operation. After that, the process proceeds to step S204.

(Step S204) The mobile phone 20 transmits a connection request signal to which the system identification information of the in-vehicle system 10 is added to the server device 30 via the first network. After that, the process proceeds to step S205.

(Step S205) The server device 30 stores the connection request signal received from the mobile phone 20 in association with the system identification information added to the connection request signal. Further, when actively transmitting (pushing) information to the in-vehicle system 10, the server device 30 adds the information to be transmitted (pushed) and then receives a connection request from the mobile phone 20. Send a connection response signal to the signal.
When the mobile phone 20 receives the connection response signal from the server device 30, the mobile phone 20 extracts the information added to the connection response signal by the server device 30 and transfers the information extracted by using the cooperative operation function to the in-vehicle system 10. ..

In the present embodiment, among the processes shown in FIG. 5, the process of step S101 may be started without performing the processes of steps S201 and S202.

As described above, in the in-vehicle system 10 according to the present embodiment, the server device 30 actively refers to the in-vehicle system 10 without recognizing the cooperative operation state between the in-vehicle system 10 and the mobile phone 20. Information can be sent (pushed).
With this configuration, the in-vehicle system 10 can autonomously start the cooperative operation with the mobile phone 20 without notifying the server device 30 of the cooperative operation state.

(Third Embodiment)
Next, a third embodiment of the present invention will be described. The same components as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be incorporated. In the following description, the differences from the above-described embodiment will be mainly described.

FIG. 6 is a schematic block diagram showing a configuration example of the communication system 1 according to the present embodiment.
The communication system 1 further includes an in-vehicle system 10, a mobile phone 20, a server device 30, and an information management device 40.

The control unit 11 of the in-vehicle system 10 determines that the cooperative operation state of the mobile phone 20 is being linked by the cooperative operation state determination process, and then transmits a profile change request to the information management device 40 via the communication module 13. The profile change request is a control signal indicating a change from the profile in use to the profile of the own system that is the cooperation source in the mobile phone 20 that is the cooperation destination of the operation cooperation.

The information management device 40 is a component device of the core network of the first network, and is a subscriber information management device that holds subscriber data. In the present embodiment, the subscriber data is configured for each contract, including profile identification information and a set of profiles identified by the profile identification information. Each profile has a set of terminal identification information and subscriber identification information.

When the information management device 40 receives the profile change request from the in-vehicle system 10, the information management device 40 reads out the profile of the in-vehicle system 10 of the cooperation source instructed by the profile change request from the subscriber data. The information management device 40 transmits the read profile to the mobile phone 20 of the cooperation destination instructed by the profile change request.

The control unit 21 of the mobile phone 20 receives a profile from the information management device 40 via the communication unit 22, and stores the received profile in the storage unit 24. The control unit 21 validates the validity of the received profile and invalidates the validity of the other profiles among the stored profiles. The control unit 21 of the mobile phone 20 notifies the communication unit 22 of a valid profile after it is determined in the connection confirmation process that the connection with the communication module 13 of the in-vehicle system 10 is possible. After that, the control unit 21 transmits a switching completion notification indicating the completion of profile switching to the server device 30 via the communication unit 22. After that, the control unit 21 starts a cooperative operation with the in-vehicle system 10.

Next, the cooperative operation start processing according to the present embodiment will be described.
FIG. 7 is a sequence diagram showing an example of the cooperative operation start processing according to the present embodiment.
The process shown in FIG. 7 includes steps S101-S107, S301, and S302.
In the process of step S103, after the control unit 11 determines that the linked operation state of the mobile phone 20 is being linked, the process proceeds to step S301. The timing of executing the process of step S301 may be after the process of step S103, before or after the process of step S104.

(Step S301) The control unit 11 of the in-vehicle system 10 transmits a profile change request indicating that the profile of the mobile phone 20 is changed to the profile of the own system to the information management device 40 via the communication module 13. After that, the process proceeds to step S302. Further, the control unit 11 proceeds to the process of step S107 after receiving the communication function stop request (communication module OFF request) from the server device 30.

(Step S302) The information management device 40 reads out the profile of the vehicle-mounted system 10 specified by the profile change request from the control unit 11 of the vehicle-mounted system 10 from the subscriber data stored in advance. The information management device 40 transmits the read profile to the mobile phone 20 of the cooperation destination specified in the profile change request. The control unit 21 of the mobile phone 20 receives the profile of the in-vehicle system 10 of the cooperation source from the information management device 40 via the communication unit 22, stores it as an effective profile in the storage unit 24, and stores it in the storage unit 24. Disable other profiles. Further, the control unit 21 notifies the communication unit 22 of a valid profile, and enables access to the first network by the notified profile.

After that, in the process of step S106, after receiving the cooperation operation start request from the server device 30, the process proceeds to step S107.
In step S107, the in-vehicle system 10 and the mobile phone 20 start a cooperative operation. After that, the process shown in FIG. 7 is terminated.

In the process of FIG. 7, similarly to the process shown in FIG. 4, the in-vehicle system 10 transmits a cooperative operation status notification to the server device 30 (step S104), and then the server device 30 requests the in-vehicle system 10 to stop the communication function. A case of transmission (communication module OFF request, step S105) is taken as an example. Similar to the example shown in FIG. 5, the above-mentioned processes of steps S301 and S302 are executed immediately before or immediately after the transmission when the in-vehicle system 10 transmits the cooperation operation start request to the mobile phone 20 (step S203). May be done. This makes it possible to access the first network by the notified profile.

As described above, in the vehicle-mounted system 10 according to the present embodiment, the control unit 11 transmits a request for switching to the communication profile to the vehicle-mounted system 10 to the information management device 40 of the network connected to the mobile phone 20. Then, the mobile phone 20 is made to provide the communication profile.
With this configuration, access using the communication profile can be realized without having to store the communication profile of the in-vehicle system 10 in the storage unit 24 of the mobile phone 20 in advance. Since it is not necessary to attach / detach the storage medium for setting the communication profile of the in-vehicle system 10 and other operations, the convenience of operation cooperation with the mobile phone 20 is enhanced.

Although the embodiments of the present invention have been described in detail above, the specific configuration is not limited to the above, and various design changes and the like can be made without departing from the gist of the present invention. be.
