Description

  The present invention relates to a wireless communication method, a wireless communication program, a wireless communication device, a base station, and a wireless communication system for allowing other wireless communication devices to proxy data transmission / reception.

Conventionally, wireless communication devices such as mobile phones and smartphones wirelessly transmit and receive data to and from base stations using radio waves, and acquire various types of data such as voice, images, and characters. Depending on the location, the radio field strength may be poor, such as when you are inside a building that is difficult to transmit radio waves, when you are underground, or when you are inside a tunnel. In such a case, the RSSI (Receive Signal Strength Indication, reception strength) of the wireless communication device is lowered, and data cannot be transmitted / received.

  Therefore, conventionally, there is a technique in which a proxy device receives a signal and transmits it to a target device using another radio wave in a place where the radio wave intensity is poor. Conventionally, there is a technique in which a mail server receives mail as a proxy for the device and then distributes it to a predetermined device. Further, conventionally, there is a method of notifying that there is an incoming call by a device that has received a proxy incoming call (see, for example, Patent Documents 1 to 3).

  However, in the above-described conventional method, only the radio wave intensity is used as a determination material for determining whether or not to perform proxy communication. For example, there is no mechanism for requesting proxy communication based on the remaining battery level of the wireless communication device. Therefore, in the conventional method, if the battery runs out during communication with the base station, communication with the base station is interrupted.

  Further, the proxy communication device according to the conventional method is a fixed device such as a base station, and transmission / reception of data by proxy communication between wireless communication devices is not realized. Therefore, in the conventional method, appropriate proxy communication has not been realized depending on the situation of the wireless communication device.

  In view of such a problem, the disclosed technology aims to realize appropriate proxy communication according to the situation of the wireless communication device.

  The wireless communication method according to an aspect of the disclosure detects the reception intensity of the radio wave from the base station by the first communication unit and the amount of power of the internal power supply, and the detected result satisfies a preset proxy communication condition The second communication means transmits a proxy communication request for causing the other radio communication device to perform proxy communication with the base station, and receives a permission notification for the proxy communication request from the other radio communication device. , Encrypting data to be transmitted to the base station, and transmitting the encrypted data to the other wireless communication device by the second communication means.

  In the present embodiment, when the communication management means 37 described above performs proxy communication by lending to another wireless communication device 11, the communication database stores the device ID sent simultaneously with the request signal and the address information corresponding to the device ID. 23. For example, in the example of FIG. 6A, the device ID “001” and the corresponding address information “aaa” are stored. In the present embodiment, proxy communication may be performed by lending to a plurality of wireless communication devices 11. In this case, as shown in FIG. 6A, in addition to the device ID “001”, the device ID Address information “bbb” corresponding to “002” is stored.

  In the present embodiment, the above-described communication management unit 37 is selected to perform proxy communication among the wireless communication devices 11 that have received the permission notification when borrowing another wireless communication device 11 to perform proxy communication. Address information (for example, “ccc”) of the wireless communication device 11 is stored in the communication database 23. In the present embodiment, device ID information may be stored together with address information.

  Further, the contents of the communication database 23 described above are cleared (deleted) when the proxy communication ends.

  6B includes, for example, “ID (device ID)”, “communication amount (packet)”, “number of times of communication”, and the like, but is not limited thereto. . 6C includes, for example, “ID (device ID)”, “proxy traffic (packet)”, “number of proxy communications”, and the like, but is not limited thereto. It is not a thing. For example, in the present embodiment, the item “number of communication” may not be included in the content of FIG. 6B, and the item “number of proxy communication” may not be included in the content of FIG.

  In the present embodiment, the above-described communication control unit 65 determines whether the communication amount of the received communication data is a normal communication amount for the wireless communication device 11 or a proxy communication amount. In the present embodiment, if the determination result described above is a normal communication amount, an ID (for example, “001”) corresponding to the communication data and the communication amount are stored in the communication amount database shown in FIG. (For example, “200 packets”) and the number of communications (for example, “10 times”) are stored. Here, if the same ID already exists in the traffic volume database, the current traffic volume and the communication count (one time) are added to the traffic volume and the communication count stored in the database, respectively, and the value is updated. Is done. Note that the communication amount is in packet units in the example of FIG. 6B, but is not limited to this, and may be in byte units, for example.

  Further, in the present embodiment, if the determination result described above is the proxy traffic, it is stored in the proxy traffic database shown in FIG. For example, in the present embodiment, the ID (for example, “001”) of the wireless communication device 11 (the lent wireless communication device 11) that proxy-communication the communication data, the proxy communication amount (for example, “30 packets”), The proxy communication count (for example, “twice”) is stored. Here, when the same ID already exists in the proxy traffic database, the proxy traffic and the proxy communication (1 time) are added to the proxy traffic and proxy communication stored in the database, respectively. And the value is updated. The proxy communication amount is in packet units in the example of FIG. 6C, but is not limited to this, and may be in byte units, for example.

  Here, the communication data for proxy communication received by the base station 12 includes data of the wireless communication device 11 borrowed from another wireless communication device 11. Therefore, at the time of proxy communication, in addition to the data storage in the proxy communication amount database shown in FIG. 6C, the ID and communication amount of the borrowed wireless communication device 11 are stored in the communication amount database shown in FIG. And the number of communications may be stored.

  Note that the database information shown in FIGS. 6B and 6C is used at the time of the accounting process and is deleted after the accounting process. That is, the database shown in FIGS. 6B and 6C stores the amount of communication and the number of communication for a predetermined period during which the accounting process is performed. In the present embodiment, the present invention is not limited to this. For example, statistical information so far may be stored in a statistical database or the like. Moreover, although the above-mentioned content showed the example in case the base station 12 received communication data, also when transmitting data from the base station 12, it is various with respect to a traffic volume database and a proxy traffic volume database similarly. Data is stored.

  6D includes items such as “ID (device ID)”, “address information”, “user information (here, user ID, etc.)”, “key information (for example, Including, but not limited to, “encryption key and decryption key” and “utilization fee (yen)”. For example, FIG. 6D may include, for example, usage contract information between the user and the base station 12, point information, and the like.

In the present embodiment, by using the above-described database, it is possible to appropriately manage the communication amount, communication frequency, usage fee, etc. for each ID.

<Example of proxy communication processing>
Next, an example of proxy communication processing in the present embodiment will be described. FIG. 7 is a sequence diagram illustrating an example of proxy communication processing in the present embodiment. In FIG. 7, as an example, two wireless communication devices 11-1 and 11-2 and a base station 12 are included, and the wireless communication device 11-1 substitutes the wireless communication device 11-2 (wireless communication device). 11-2) to perform proxy communication processing with the base station 12.

  In FIG. 7, in the proxy communication process, a condition for borrowing is first set in the wireless communication apparatus 11-1, and a condition for lending is set in the wireless communication apparatus 11-2 (S 01 and S 02). In the example of FIG. 7, it is assumed that the wireless communication apparatuses 11-1 and 11-2 are configured to perform proxy communication (the proxy communication ON state when borrowing or lending). Further, the processes of S01 and S02 may be set in advance before the proxy communication process.

  Here, the wireless communication device 11-1 determines whether or not a borrowing condition is satisfied (S03). For example, as described above, whether or not the borrowing condition is satisfied is determined when the remaining battery level is a predetermined value (for example, 30%) or less and / or the communication quality is set to a preset value (for example, 5 It can be determined by setting whether the stage (5 is the best) or worse than 2) and satisfying the setting conditions. The borrowing conditions are not limited to this, and may be set conditions such as when there is no radio wave condition that allows direct communication with the base station 12 or when the remaining battery level is less than a predetermined value.

  Here, when the conditions for borrowing are not satisfied (NO in S03), the wireless communication device 11-1 communicates with the base station 12 using its own first communication means 21 and the like. In the example of FIG. 7, the proxy communication process is described to return to the process of S03, but the process may be terminated as it is.

  If the wireless communication device 11-1 satisfies the borrowing condition (YES in S03), the wireless communication device 11-1 makes a request for proxy communication and its own device ID (proxy) in near field communication using the second communication means 22. (Communication request) is broadcasted to other wireless communication devices 11 in the vicinity (S04).

  The wireless communication device 11-2 is a device in a position where the wireless communication device 11-1 can communicate with the wireless communication device 11-1. In this case, a position where communication is possible via the relay device 13 is also included. When the wireless communication device 11-2 receives the corresponding signal by the process of S04 described above, it determines whether or not the lending condition set by the process of S02 described above is satisfied (S05).

  The lending condition is, for example, a case where the remaining battery capacity is greater than a predetermined value (for example, 30%) and can be transmitted / received to / from the base station 12, but is not limited thereto.

  If the wireless communication device 11-2 does not satisfy the lending condition described above (NO in S05), the wireless communication device 11-2 rejects the proxy communication. In the case of refusal, for example, as shown in the example of FIG. 7, a refusal notice is transmitted to the wireless communication device 11-1 (S06). Further, in the case of refusal, the request from the wireless communication device 11-1 may be simply discarded without transmitting the refusal notification as described above.

  If the wireless communication device 11-2 satisfies the lending condition (YES in S05), the wireless communication device 11-2 transmits a proxy communication permission notification to the wireless communication device 11-1 (S07), and performs proxy communication to the communication database 23 described above. Update (register) the device ID of the wireless communication device 11-1 that performs (S08). In the process of S08, address information for transmission / reception data may be registered in association with the device ID. Thereby, the wireless communication device 11-2 can perform proxy communication of the wireless communication device 11-1.

  Upon receiving the proxy communication permission communication from the wireless communication device 11-2, the wireless communication device 11-1 encrypts the data to be subjected to the proxy communication with its own key information (encryption key) (S09). The encrypted data (encrypted (A) in the example of FIG. 7) is transmitted to the wireless communication apparatus 11-2 (S10). The wireless communication device 11-1 may register the address information and the like of the wireless communication device 11-2 that has received the permission communication before the above-described processing of S09 in the communication database 23 of itself.

  The wireless communication device 11-2 receives the data (encryption (A)) from the wireless communication device 11-1, and generates communication data for proxy transmission of the received data to the base station 12 (S11). In the process of S11, the ID (device ID or the like) of the wireless communication device 11-1 acquired from the communication database 23 is added to the communication data to be generated in order to indicate the proxy communication. The ID of the wireless communication device 11-1 can be acquired by referring to the communication database 23 using address information included in header information of transmitted data (encryption (A)), for example. It is not limited to this.

  The wireless communication device 11-2 encrypts the generated communication data with its own encryption key (S12), and uses the encrypted data (encrypted (B) in the example of FIG. 7). It transmits to the base station 12 (S13).

  The base station 12 receives the communication data (encryption (B)) transmitted from the wireless communication device 11-2 and decrypts the encrypted data of the received communication data. Specifically, the encryption (B) is decrypted (B) using the key information (decryption key) corresponding to the transmitted wireless communication device 11-2 (S14), and then included in the decrypted data The encrypted (A) is decrypted (A) using the key information (decryption key) corresponding to the wireless communication device 11-1 (S15). Thereby, the base station 12 can acquire the content of the communicated data.

  Next, the base station 12 acquires the communication amount of the communicated data (S16). In the example of FIG. 7, the communication amount of the communicated data is the communication amount of the wireless communication device 11-1 and further the proxy communication amount of the wireless communication device 11-2. This can be determined, for example, from the address information of the transmission source of the received data and the ID included in the received data. Therefore, the base station 12 stores the communication amount of the current communication data in the communication amount database of the storage unit 63 as the communication amount of the wireless communication device 11-1. Note that if the communication volume up to the previous time has already been recorded, the base station 12 adds the current traffic volume to the previous traffic volume and updates the data. Further, the base station 12 stores the communication amount of this communication data in the proxy communication amount database of the storage unit 63 as the proxy communication amount of the wireless communication device 11-2. In addition, when the proxy traffic until the previous time is already recorded, the base station 12 adds the current proxy traffic to the previous proxy traffic and updates the data. Each database may store the number of times of communication (add +1 if the number of times is already recorded). In the present embodiment, by using this communication amount and / or the number of times of communication, each wireless communication device 11-1 and 11-2 can be charged (including incentives). .

  In addition, when transmitting data to the wireless communication device 11-1 using the proxy communication described above, the base station 12 performs transmission in the reverse procedure to that described above. Specifically, the base station 12 first encrypts the data by encryption (A) with key information (encryption key) corresponding to the wireless communication device 11-1 (S17), and then performs wireless communication. Encryption is performed by encryption (B) using key information (encryption key) corresponding to the device 11-2 (S18). Further, the base station 12 transmits the encrypted communication data (encryption (B) in the example of FIG. 7) to the wireless communication device 11-2 (S19).

  The base station 12 updates the normal traffic for the transmitted data (S20). Specifically, the base station 12 stores the communication amount of the transmitted data in the communication amount database of the storage unit 63 as the communication amount of the wireless communication device 11-1. Further, as described above, when the communication volume up to the previous time has already been recorded, the base station 12 updates the data by adding the current communication volume to the previous communication volume.

  Further, the base station 12 updates the proxy communication amount for the transmitted data (S21). Specifically, the base station 12 stores the communication amount of the transmitted data in the proxy communication amount database of the storage unit 63 as the proxy communication amount of the wireless communication device 11-2. Further, as described above, when the proxy communication volume up to the previous time is already recorded, the base station 12 adds the current proxy communication volume to the previous proxy communication volume and updates the data. Each database may store the number of times of communication (add +1 if the number of times is already recorded).

  The wireless communication device 11-2 decrypts the communication data obtained from the base station 12 using its own key information (decryption key) (S22), and analyzes the ID included in the decrypted data (S23). . At this time, the wireless communication device 11-2 can refer to the communication database 23 and know that the ID corresponds to the wireless communication device 11-1. Therefore, the wireless communication device 11-2 generates communication data for transmitting data to the wireless communication device 11-1 corresponding to the analyzed ID (S24), and the generated communication data is transmitted to the wireless communication device 11-1. Transmit (S25). The data at this time is communication data encrypted by encryption (A).

  The wireless communication device 11-1 receives the communication data transmitted from the wireless communication device 11-2, decrypts the received communication data with its own key information (for example, a decryption key) (S26), Data from the base station 12 can be acquired. Further, the wireless communication device 11-1 completes communication after data acquisition (S27). When completing the proxy communication, the wireless communication device 11-1 may transmit a proxy communication end signal indicating that to the wireless communication device 11-2.

  The wireless communication device 11-2 receives the proxy communication end signal from the wireless communication device 11-1 when there is no communication from the wireless communication device 11-1 for a predetermined time or more after the predetermined time has elapsed. The information for the wireless communication device 11-1 in the communication database 23 is deleted (cleared) and the proxy communication is terminated. By performing the processing described above, proxy communication according to the present embodiment can be performed.

  In the above-described processing of S04, communication by broadcast is performed. However, in the present embodiment, the present invention is not limited to this. For example, even if data is transmitted to the terminal that performed proxy communication last time Good. That is, in the process of S04, one or a plurality of devices may be limited and a proxy communication request may be transmitted.

<Example of data structure of communication data in proxy communication processing>
Here, an example of the data structure of communication data in the proxy communication process described above will be described with reference to the drawings. FIG. 8 is a diagram for explaining an example of the data structure of communication data in the proxy communication process. In FIG. 8, as an example, data for the wireless communication device 11-1 transmitted from the base station 12 is proxy-communicated by the wireless communication device 11-2.

  FIG. 8A shows an example of the data structure of communication data transmitted from the base station 12 to the wireless communication apparatus 11-2. The wireless communication device 11-2 recognizes that the communication data has been transmitted to itself from the address information included in the header information (Header1) of the data, and the contents of the data part (Data0) are obtained by decoding processing or the like. To get. In addition, as shown in FIG.8 (b), Data0 shall contain apparatus ID and the content (Data1) of a data part, as shown in FIG.8 (b). Note that the device ID does not have to be at the head of the decoded data of Data0, and may be at a preset position.

  In the present embodiment, Data1 is encrypted data that can be decrypted only by the wireless communication device 11-1, for example. Therefore, the contents of Data1 cannot be decoded by the wireless communication device 11-1.

  The wireless communication device 11-2 uses the ID information shown in FIG. 8B to search the ID information of the wireless communication device 11 currently performing proxy communication included in its own communication database 23, and from the device ID It acquires that it is communication data to the wireless communication apparatus 11-1. Therefore, the wireless communication device 12-2 adds the header information (Header2) for transmission to the wireless communication device 11-1 to generate the communication data illustrated in FIG. 8C, and the generated communication data is wirelessly communicated. It transmits to the apparatus 11-1.

  When the wireless communication device 11-1 receives the communication data shown in FIG. 8C, the wireless communication device 11-1 performs decryption using its own decryption key, and obtains significant data (Data2) shown in FIG. 8D. be able to.

  When transmitting communication data from the wireless communication device 11-1 to the base station 12 via the proxy communication of the wireless communication device 11-2, the procedure reverse to the above-described FIGS. The data structure is ((d) → (c) → (b) → (a)).

  In the above description, an example is shown in which only the wireless communication device 11-2 performs proxy communication to perform communication between the base station 12 and the wireless communication device 11-1, but the present embodiment is not limited thereto. Alternatively, for example, a plurality of wireless devices may be proxy-communicated in a daisy chain. The data structure in that case is, for example, stored in a so-called nested structure according to the order in which the above-described ID-added data is transmitted, and the above-described processing is repeated, so that the base station 12 can perform the target wireless communication device The data is transmitted to 11.

<Example of billing process>
Next, an example of charging processing at the base station 12 in the present embodiment will be described with reference to the drawings. FIG. 9 is a diagram illustrating an example of the billing process. As shown in FIG. 9, in the billing process according to the present embodiment, the information such as the normal communication amount, the proxy communication amount, and the proxy communication count managed by the communication control means 65 provided in the base station 12 is used. The charging unit 66 performs charging. In addition, each information mentioned above is memorize | stored in the memory | storage means 63 as a traffic volume database and a proxy traffic volume database, for example.

  Here, in this embodiment, an incentive is given to the wireless communication apparatus 11 that has performed proxy communication in the billing process. Therefore, in the present embodiment, when calculating the usage fee, for example, a charging process such as “use fee = α × communication amount−β × proxy communication amount” is performed. The usage fee indicates the usage fee of the wireless communication device 11, the communication amount indicates the communication amount of the wireless communication device 11, and the proxy communication amount indicates the proxy communication amount of the wireless communication device 11. Α represents a traffic coefficient, and β represents a proxy traffic coefficient.

  That is, in the example of FIG. 9, “α × communication amount” is set according to the data communication amount obtained from the communication amount database. The communication amount coefficient α can be changed according to, for example, the normal communication amount and the number of communication. For example, when the communication amount or the number of communication is large, the communication amount coefficient is set low. In the example of FIG. 9, “β × proxy traffic” is set according to the data traffic obtained from the proxy traffic database. The proxy communication amount coefficient β can be changed according to, for example, the proxy communication amount and the number of communication. For example, when the proxy traffic volume and the proxy communication count are large, the proxy traffic volume coefficient is set high.

  In this embodiment, an incentive can be given to the wireless communication device 11 that has performed proxy communication by subtracting the amount of “β × proxy communication amount” from “α × communication amount” that is a normal communication amount. .

  Note that the accounting calculation method is not limited to this. For example, the communication amount coefficient may be set based on only the communication amount or the communication frequency, or the proxy communication based on only the proxy communication amount or the proxy communication number. A quantity coefficient may be set.

  Furthermore, as an example of other incentives, for example, points may be given to the user according to the amount of proxy communication and / or the number of proxy communications, gifts may be given, other services can be used, etc. Special treatment and benefits may be given.

  According to the embodiment described above, appropriate proxy communication can be realized according to the situation of the wireless communication device. Specifically, even when wireless communication measures are in a place where radio waves do not reach the base station directly, use radio waves by communicating with the base station using radio communication devices in better environmental conditions. Efficiency can be improved. Moreover, in this embodiment, the battery of another radio | wireless communication apparatus can be shared, and self battery exhaustion can be avoided.
