Description

  The present invention relates to a communication cooperation system including, for example, a control device mounted on a vehicle and a mobile terminal such as a mobile phone connected to the control device.

  2. Description of the Related Art Conventionally, there are application programs (hereinafter, referred to as “apps” as appropriate) that are executed in an in-vehicle device such as a car navigation device, for example, that receive information from an external server device via a network to realize a predetermined function. Specifically, the audio application receives radio audio data and performs audio output based on the audio data. Moreover, it is exemplified that the news display application receives the news data and performs display output based on the news data.

  In such a case, it is conceivable to use a mobile terminal such as a mobile phone for data communication between the in-vehicle device and the server device. At this time, since there is an upper limit on the communication speed of the mobile terminal and the like, if the amount of communication data increases, the responsiveness of the app may decrease.

  Therefore, for data that is displayed and output on the in-vehicle device, a drawing part is stored on the in-vehicle device side, and data that can identify the drawing part is communicated to reduce the amount of communication data. Is disclosed (for example, see Patent Document 1).

JP 2010-185779 A

  However, it is not only data that can be converted into parts as drawing parts. In addition, there is a possibility that the communication state of the mobile terminal is deteriorated due to various factors. In the technique described in Patent Document 1, when the communication state of the mobile terminal deteriorates, communication delay or communication interruption may occur as a result. Concerned.

In addition, although the in-vehicle device has been described as an example, a similar problem may occur when a control device that executes an application performs data communication with a server device on a network via a mobile terminal.
The present invention has been made to solve the above-described problems, and an object of the present invention is to communicate with a mobile terminal in a communication cooperation system in which a control device and a mobile terminal cooperate to perform data communication with a server device on a network.

  The communication cooperation system (10) of the present invention made to achieve the above object includes a control device (20) and a plurality of portable terminals (31, 32, 33). The control device executes an application program. The plurality of portable terminals establish communication with the control device, and acquire a plurality of data necessary for executing the application program from the external device (50) via the network.

  Here, in particular, in the control device, the communication operation state acquisition means (21a) acquires the communication operation states of a plurality of portable terminals. The communication operation state includes at least a communication state indicating a state of communication with the outside. Examples of the communication state include electric field strength and communication network usage rate. In addition, an operation state indicating an operation state of the mobile terminal itself may be included in the communication operation state. Examples of the operating state include battery remaining capacity and CPU usage rate.

  Then, by assigning data to be acquired to a plurality of portable terminals from a plurality of data based on the communication operation state acquired by the communication operation state acquisition unit by the communication content determination unit (21b), The communication content of the terminal is determined.

  That is, in the present invention, on the premise of connection with a plurality of portable terminals, data to be acquired is allocated to the plurality of portable terminals based on the communication operation state of the portable terminal. In this way, communication delays and communication interruptions can be reduced as much as possible even under conditions where the communication state of the mobile terminal is deteriorating.

  In addition, it can also be realized as an invention of a control device that constitutes a communication cooperation system.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The communication cooperation system 10 illustrated in FIG. 1 includes an in-vehicle device 20 and three mobile terminals 31, 32, and 33.

  The in-vehicle device 20 is mounted on a vehicle. For example, it is embodied as a navigation device. The mobile terminals 31 to 33 are embodied as mobile phones that are brought into the vehicle. In addition, when distinguishing the three mobile terminals 31 to 33, symbols A to C in the drawing are used, and they are described as an A mobile terminal 31, a B mobile terminal 32, and a C mobile terminal 33.

  The in-vehicle device 20 is connected to the external server device 50 via the A to C portable terminals 31 to 33. With this configuration, data necessary for executing the application is acquired from the external server device 50.

The in-vehicle device 20 includes a control unit 21, an output unit 22, and a communication unit 23.
The control unit 21 is configured as a so-called computer system, and includes a CPU, a ROM, a RAM, an I / O, and a bus line connecting them.

The output unit 22 is configured to perform display output and audio output accompanying application execution. Therefore, it is embodied as a display or a speaker.
The communication part 23 is a structure for establishing communication between the portable terminals 31-33 of AC. For example, when Bluetooth, which is a short-range wireless communication standard, is used, it is configured with a Bluetooth chip or the like. Of course, Wi-Fi can also be used.

  The mobile terminals 31 to 33 of A to C are embodied as mobile phones. These portable terminals 31 to 33 are brought into the vehicle. For example, the mobile terminals 31 to 33 of A to C are three mobile phones that the driver and the passenger have.

  The mobile terminals 31 to 33 of A to C have in-vehicle device communication units 41, 42, and 43 and server communication units 44, 45, and 46, respectively. The in-vehicle device communication units 41 to 43 are configured to establish communication with the in-vehicle device 20. On the other hand, the server communication units 44 to 46 are configured to establish communication with the server device 50.

  The server device 50 includes a server-side communication unit 51 for performing data communication with the mobile terminals 31 to 33 of A to C, an information database 52 in which data necessary for executing the application of the in-vehicle device 20 is accumulated, have.

  Next, data communication processing will be described with reference to FIG. This data communication process is executed by the control unit 21 of the in-vehicle device 20 as the application is executed. Here, this application is a vehicle application (navigation application, vehicle audio application, etc.) that is executed by the in-vehicle device 20, and is an application that is executed by the mobile terminal alone (in a state where it is not connected to the in-vehicle device 20). The explanation is based on a different assumption.

  In the first S100, terminal connection processing is performed. This process is for establishing communication with the mobile terminals 31 to 33 of A to C. As described above, Bluetooth or Wi-Fi of the short-range wireless communication standard is used.

  In continuing S110, it is judged whether the data of the server apparatus 50 are required. This process determines whether or not data from the external server device 50 is necessary for the application being executed. Here, when it is determined that the data of the server device 50 is necessary (S110: YES), the process proceeds to S120. On the other hand, when it is determined that the data of the server device 50 is unnecessary (S110: NO), the subsequent process is not executed and the data communication process is terminated.

  In S120, data information is acquired. In this process, item information of data necessary for the application and the data amount for each data in the item information are acquired from the server device 50.

  In continuing S130, a communication operation state is acquired. This process acquires the communication operation state in the portable terminals 31 to 33 from the portable terminals 31 to 33 having established communication states. The communication operation state includes a communication state indicating the state of communication with the outside and an operation state indicating the operation state of the mobile terminal itself. Examples of the communication state include electric field strength and communication network usage rate. Further, the operation state is exemplified by the remaining battery level and the CPU usage rate.

  In next step S140, it is determined whether or not the communication operation state has changed. Here, by storing the previous communication operation state, it is compared with the current communication operation state, and it is determined whether or not the information included in the communication operation state has changed by a predetermined amount or more. Note that an affirmative determination is also made here in the initial state immediately after communication is established. If it is determined that the communication operation state has changed (S140: YES), a communication content determination process is executed in S150, and then the process proceeds to S170. On the other hand, when it is determined that the communication operation state has not changed (S140: NO), the communication content is maintained in S160, and then the process proceeds to S170.

  In S170, data acquisition is instructed. This process instructs the mobile terminals 31 to 33 of A to C which data to acquire. This instruction is based on the allocation of the mobile terminals 31 to 33 by the communication content determination process of S150.

In subsequent S180, data is received. In this process, data transmitted from the server device 50 is received via the mobile terminals 31 to 33 of A to C.
In the next S190, it is determined whether or not the data reception is completed. This determination is made for each data item. If it is determined that the data reception is completed (S190: YES), the data is integrated and output in S200, and then the process proceeds to S210. The data is output to the output unit 22 in FIG. Thereby, display output and audio output are realized. On the other hand, when it is determined that the data reception has not ended (S190: NO), the processing from S130 is repeated.

  In S210, it is determined whether data communication is completed. This process determines whether or not all the data items acquired in S120 have been acquired. If it is determined that the data communication is completed (S210: YES), the data communication process is terminated. On the other hand, while the data communication is not completed (S210: NO), the processing from S120 is repeated.

Next, the communication content determination process of S150 will be described based on the flowchart of FIG.
In the first S151, the data communication is stopped. This process temporarily stops data communication prior to changing the allocation of data to be acquired for the portable terminals 31 to 33.

  In continuing S152, it is judged whether there exists any terminal which cannot communicate. Examples of terminals that cannot communicate are terminals among AC portable terminals 31 to 33 whose electric field strength has been extremely reduced due to leaving the communication area. Further, a terminal whose battery remaining amount is “0” is exemplified. Furthermore, a terminal whose communication network usage rate has become 100% is exemplified. Further, a terminal whose CPU usage rate has become 100% is exemplified. If it is determined that there is a terminal that cannot communicate (S152: YES), the terminal is excluded in S153, and then the process proceeds to S155. On the other hand, if it is determined that there is no terminal that cannot be communicated (S152: NO), if there is a terminal that has been excluded in S154, the terminal is returned, and then the process proceeds to S155.

In S155, the priority is determined. In this process, the priority relating to data allocation is determined for the mobile terminals 31 to 33 of A to C.
Specifically, an evaluation in five stages of “1” to “5” is added based on the numerical values of four pieces of information of electric field strength, battery remaining amount, network usage rate, and CPU usage rate. The evaluation value increases as the electric field strength increases. Moreover, the evaluation value becomes large, so that battery remaining amount is large. The larger the network usage rate, the smaller the evaluation value. The evaluation value decreases as the CPU usage rate increases. Note that these four pieces of information may be weighted. For example, in the present embodiment, the information on the electric field strength is weighted twice.

  In the example of FIG. 4A, the A mobile terminal 31 has the electric field strength “10 (5 × 2)”, the remaining battery level “4”, the network usage rate “5”, and the CPU usage rate “5”. The overall evaluation score is “24”. The B mobile terminal 32 has an electric field strength of “8 (4 × 2)”, a remaining battery level of “3”, a network usage rate of “3”, and a CPU usage rate of “4”, resulting in an overall evaluation score of “18”. ing. The C mobile terminal 33 has an electric field strength of “6 (3 × 2)”, a remaining battery level of “2”, a network usage rate of “4”, and a CPU usage rate of “5”, and an overall evaluation score of “17”. ing. Accordingly, the priority is determined in the order of A mobile terminal 31 → B mobile terminal 32 → C mobile terminal 33.

  When the communication operation state changes as shown in FIG. 2, the communication content determination process is executed (S140: YES, S150), but the A mobile terminal 31 is used for another purpose such as a telephone call or Internet connection. For example, the evaluation of the network usage rate and the CPU usage rate may be lowered. For example, in FIG. 4B, for the A mobile terminal 31, both the network usage rate and the CPU usage rate are “1”, and the overall evaluation score is “16”. Therefore, when there is such a change in the communication operation state, the priority is redetermined in the order of B mobile terminal 32 → C mobile terminal 33 → A mobile terminal 31.

  Returning to FIG. 3, in S156, the importance of the data is determined. It has already been described that the item information of data necessary for the application and the data amount for each data in the item information are acquired from the server device 50 (S120 in FIG. 2). By the way, there is a difference in the importance of data required for the application. Therefore, the importance of data is set here.

  The importance of data is determined by the app importance and the information importance. The app importance level is evaluated in five stages from “1” to “5”. For the app importance, for example, the app is necessary for driving the vehicle, and the evaluation value is higher.

  In FIG. 5A, the navigation app has an app importance “5”, the audio app has an app importance “3”, and the news display app has an app importance “2”. This is because a navigation application that provides route guidance is more important than a news display application that displays news while traveling. This app importance does not have to be a fixed value. For example, when the vehicle is stopped, it may be possible to lower the importance of the navigation application and increase the importance of the news display application.

The information importance indicates superiority or inferiority in data required by the application. Information importance is also evaluated in five stages, “1” to “5”.
In FIG. 5B, the information importance regarding the navigation application is current location information “5”, route information “4”, and peripheral facility information “2”. Also, the information importance regarding the audio application is radio sound “4” and BT audio sound “3”. Furthermore, the information importance regarding the news display application is traffic information news “4” and general news “2”. With regard to the navigation application, the current location information has a relatively high degree of importance when considering driving of the vehicle. However, like the app importance, the information importance may not be a fixed value. For example, when traveling to an unknown land starting from the vicinity of the home, it is possible to decrease the importance of the current location information and increase the importance of the route information. This is to give priority to the route information over the familiar current location information around the home. Of course, if you drive to some extent and deviate from the normal range of action (this can be identified from the driving history), the current location information will also be important, so restore the importance of the current location information once lowered (increase the importance) ) Is also possible.

  As shown in FIG. 5B, the importance of data is set as the sum of information importance and application importance. Here, the current location information is “10”, the route information is “9”, the surrounding facility information is “7”, the radio voice is “7”, the BT audio voice is “6”, the traffic information news is “6”, and the general news Is “4”.

  In S157 in FIG. 3, the communication content is determined. This process allocates the A to C portable terminals 31 to 33 in order from the data having the highest data importance set in S156 based on the priorities of the A to C portable terminals 31 to 33 determined in S155. is there.

  In subsequent S158, data communication is resumed. This process is to resume data communication that has been temporarily stopped prior to changing the allocation of data to be acquired for the portable terminals 31 to 33.

Next, the allocation of data to the mobile terminals 31 to 33 in S157 will be described in detail.
FIG. 6A illustrates the priorities and communication speeds of the mobile terminals 31 to 33 of A to C. Here, the priority is determined in S155 in FIG. The communication possible speed is calculated from the specifications of the mobile terminals 31 to 33 of A to C, the network usage rate, the CPU usage rate, and the like. Here, the A mobile terminal 31 has a priority “1” and a communicable speed “1000”. The B mobile terminal 32 has a priority “2” and a communicable speed “300”. Furthermore, the C mobile terminal 33 has a priority “3” and a communicable speed “100”.

  At this time, as shown in FIG. 6B, the data is transferred to any one of the mobile terminals 31 to 33 of A to C according to the data importance of the data required by the application and the required speed for acquiring the data. Is allocated. Here, the data importance level is set in S156 in FIG. The required speed is calculated from the data amount of each data and the use timing in the application.

  Specifically, the data arranged in the order of the data importance are sequentially assigned to the mobile terminals 31 to 33 having the highest priority. For data with the same data importance level, priority is given to data with a high application importance level. Moreover, if there is a margin in the communicable speeds of the mobile terminals 31 to 33 of A to C, the sum of the necessary data speeds is allocated to be 80% or less of the communicable speed.

  Here, current location information, route information, and peripheral facility information are allocated to the A mobile terminal 31. When the necessary speeds of the current location information, the route information, and the surrounding facility information are combined, “400 + 100 + 300” is “800”, which is 80% of the communicable speed of the A mobile terminal 31.

  Further, radio sound and BT audio sound are allocated to the B mobile terminal 32. When the required speeds of radio voice and BT audio voice are combined, 50 + 150 is “200”, which is about 67% of the communication speed of the B mobile terminal 32.

  Furthermore, traffic information news and general news are allocated to the C mobile terminal 33. When the necessary speeds of traffic information news and general news are combined, 50 + 30 is “80”, which is 80% of the communicable speed of the C mobile terminal 33.

In this way, even when the communication operation state changes, the communication possible speed has a margin of about 20%, so that communication delay and communication interruption can be reduced as much as possible.
In FIG. 7A, unlike FIG. 6A, the communicable speed of the B mobile terminal 32 is “900”. In this way, when there is a sufficient margin for the communicable speed, data having a large data importance is allocated so as to be acquired in a superimposed manner by a plurality of terminals.

  For example, since the communicable speed of the B mobile terminal 32 is “600” larger than that in FIG. 6A, as shown in FIG. The route information is also allocated to the B mobile terminal 32. As a result, the current location information and the route information are received by the two portable terminals 31 and 32 of A and B. Note that data having a data importance level of a predetermined value or more (for example, “8” or more) may be acquired in a superimposed manner.

  In this way, for example, even when the A mobile terminal 31 becomes unable to communicate, the B mobile terminal 32 can receive important data, and communication delay and communication interruption can be reduced as much as possible.

  As shown in FIG. 8 (a), the A portable terminal 31 is used for another purpose such as a call or Internet connection, the communication possible speed of the A portable terminal 31 is “50”, and the priority is “3”. Suppose that Here, the communicable speed of the B mobile terminal 32 is “900” and the priority is “1”, the communicable speed of the C mobile terminal 33 is “200”, and the priority is “2”.

  At this time, data is assigned in the order of B mobile terminal 32 → C mobile terminal 33 → A mobile terminal 31 in order of data importance. In this case, the current location information, route information, peripheral facility information, and radio sound are allocated to the B mobile terminal 32, BT audio sound and traffic information news are allocated to the C mobile terminal 33, and the A mobile terminal 31 is allocated to the A mobile terminal 31. General news is allocated. Here, since there is no allowance for the communicable speed, allocation exceeding 80% is performed.

  As shown in FIG. 9A, it is assumed that the communication possible speed “50” and the priority “3” remain for the A mobile terminal 31 and the communication possible speed for the B mobile terminal 32 becomes “500”. To do. Here, the priority of the B mobile terminal 32 is “1”, the communicable speed of the C mobile terminal 33 is “300”, and the priority is “2”.

  Also at this time, data is assigned in the order of B mobile terminal 32 → C mobile terminal 33 → A mobile terminal 31 in order of high data importance, but all of the data cannot be assigned. In this case, current location information and route information are allocated to the B mobile terminal 32, peripheral facility information is allocated to the C mobile terminal 33, and radio sound is allocated to the A mobile terminal 31. In addition, since there is no margin in the communication possible speed, communication of BT audio voice, traffic information news, and general news data is cancelled.

  As described above in detail, in the communication cooperation system 10 of the present embodiment, the control unit 21 of the in-vehicle device 20 performs connection processing with the mobile terminals 31 to 33 of A to C (S100 in FIG. 2), and data Item information and data amount are acquired (S120), and the communication operation states of the mobile terminals 31 to 33 of A to C are acquired (S130). Then, based on the communication operation state, a communication content determination process for allocating the data in the item information to the mobile terminals 31 to 33 of A to C is executed (S150), and the data is received (S180).

  That is, on the premise of connection with a plurality of portable terminals, data to be acquired is allocated to the plurality of portable terminals based on the communication operation state of the portable terminal. As a result, communication delays and communication interruptions can be reduced as much as possible even under conditions where the communication state of the mobile terminal is getting worse.

  In this embodiment, the communication operation states of the mobile terminals 31 to 33 of A to C are repeatedly acquired (S130 in FIG. 2), and when the communication operation state changes (S140: YES), The communication content determination process for allocating data to be acquired to the portable terminals 31 to 33 is executed again (S150). That is, the communication operation state acquisition unit 21a repeatedly acquires the communication operation states of a plurality of mobile terminals, and the communication content determination unit 21b determines the communication content of each mobile terminal again when the communication operation state changes. Thereby, even when the communication state of a portable terminal deteriorates on the way, communication delay and communication interruption can be reduced as much as possible.

  Furthermore, in this embodiment, data importance is set for each data required by the application based on the application importance and the information importance (S156 in FIG. 3), and the data is carried in descending order of the data importance. Allocation to the terminals 31 to 33 is performed (S157). That is, the communication content determination means 21b sets the data importance level for each of the plurality of data, and determines the communication content of each mobile terminal by allocating the data from the plurality of data in descending order of the data importance level. Thereby, important data among the data necessary for the application can be received more reliably.

  In the present embodiment, the priorities of the plurality of portable terminals 31 to 33 are determined based on the electric field strength, the remaining battery level, the network usage rate, and the CPU usage rate indicating the communication operation state (S155 in FIG. 3). ). That is, the communication content determination unit 21b determines the priority related to data allocation for a plurality of portable terminals based on the communication operation state. At this time, based on the determined priority of the terminal, data to be acquired is allocated to the plurality of portable terminals 31 to 33 (S157). That is, the communication content determination unit 21b determines the communication content of each mobile terminal by allocating data in order from the mobile terminal with the highest priority. Thereby, allocation of data to the portable terminals 31 to 33 becomes relatively easy.

  Moreover, in this embodiment, when determining communication content, as shown in FIGS. 6-9, the communication possible speed of the portable terminals 31-33 of AC, and the required speed at the time of receiving each data Based on the above, allocation of data to the portable terminals 31 to 33 is determined. That is, the communication content determination means 21b determines the communication content of each mobile terminal by allocating data based on the required speed, which is a communication speed required when receiving data, and the communication possible speed of the mobile terminal. Thereby, allocation of more appropriate data to the portable terminals 31 to 33 is realized.

  Furthermore, in this embodiment, it is determined whether or not there is a terminal that cannot communicate (S152 in FIG. 3). If there is a terminal that cannot communicate (S152: YES), the terminal is excluded (S153). The communication content is determined (S157). That is, the communication content determination unit 21b determines the communication content of each mobile terminal by excluding the mobile terminal that is determined to be unable to communicate based on the communication operation state. This eliminates terminals that cannot communicate prior to data allocation, thus facilitating data allocation.

  Moreover, in this embodiment, the vehicle equipment 20 mounted in a vehicle was mentioned as an example. That is, the control device is an in-vehicle device mounted on the vehicle. In the case of the in-vehicle device 20, since the wireless communication with the external server device 50 is essential, the above-described effects are conspicuous.

  In the acquisition of the data information in step S120 of FIG. 2, for example, in the initial state where communication is established, the data information is acquired by all the mobile terminals, and thereafter, the data information is periodically acquired (step S210). When the determination is negative and the process returns to step S120), it is preferable that only the terminal with the best communication operation state (high evaluation value) last time acquires the data information. In this way, the amount of communication can be reduced, and wasteful processing by terminals with other poor communication operation states can be eliminated.

  As described above, the present invention is not limited to the embodiment described above, and can be implemented in various forms without departing from the technical scope thereof.
