FIG. 1 is a block diagram showing a configuration of a communication system including a mobile phone according to the present embodiment. In FIG. 1, the configuration of parts not related to the essence of the present invention is omitted.

  A mobile phone 100 (mobile communication device) has a short-range wireless communication function and can be connected to a plurality of communication devices by short-range wireless communication or wired communication, and a mobile phone network 200 (external network). Communication unit 102 that receives an incoming notification from the communication device 102 and device information that indicates the current state of the communication device from the communication device connected to the local communication control unit 112 when the communication unit 102 receives the incoming call notification Device information acquisition unit 108 that acquires the communication information, and a device selection unit 110 that selects a communication device that performs communication for the incoming call notification based on the device information acquired by the device information acquisition unit 108.

The local wireless communication device 300 and the local wireless communication device 302 are wireless communication devices that can transmit and receive data to and from the mobile phone 100 using a short-range wireless communication technology such as Bluetooth or wireless LAN. The wired communication device 304 is a wired communication device that can transmit and receive data to and from the mobile phone 100 using a wired communication technology such as USB or serial.

  The mobile phone 100 further includes an incoming call detection unit 104, an incoming call information acquisition unit 106, a notification unit 114, an operation unit 116, a device storage unit 120, and a selection criterion storage unit 122.

The operation unit 116 includes a keypad for the user to perform various input operations, and accepts user instructions. The notification unit 114 includes a display unit that displays various messages, an operation menu for operating the mobile phone 100, and a voice output unit that performs ringtone output and alarm notification.

  The local communication control unit 112 transmits and receives data by connecting to the local wireless communication device 300, the local wireless communication device 302, and the like using a short-range wireless communication technology such as Bluetooth or wireless LAN. In addition, the local communication control unit 112 transmits and receives data by connecting to the wired communication device 304 or the like using a wired communication technology such as USB or serial. The local communication control unit 112 also has a function of holding connection management information indicating whether each communication device is connected by near field communication or wired communication.

  The device storage unit 120 stores registration information such as a device address of a local wireless communication device to which the mobile phone 100 can be connected. Registration of a wireless communication device in the device storage unit 120 may be performed by a user via the operation unit 116, or the mobile phone 100 may automatically detect and register a wireless communication device in the vicinity. it can.

  When the communication unit 102 receives an incoming call notification from the mobile phone network 200, the incoming call detection unit 104 detects an incoming call. The incoming call information acquisition unit 106 acquires incoming call information indicating the type of information from the incoming call notification received by the communication unit 102. Here, the incoming information is, for example, communication type information such as voice communication, moving image data communication, unrestricted digital data communication, or packet data communication, transmission speed, and the like.

  When the incoming call detection unit 104 detects an incoming call, the device information acquisition unit 108, based on the notification of the incoming call detection unit 104, transmits the transmission speed, remaining battery level, and usable communication from all communication devices connected to the mobile phone 100. Device information indicating the state of each communication device, such as function and radio wave quality in the case of wireless, is acquired. In the present embodiment, the radio wave quality can be the radio wave intensity.

  The device selection unit 110 performs communication for the incoming notification based on the incoming information acquired by the incoming information acquisition unit 106, the device information acquired by the device information acquisition unit 108, and the connection management information held by the local communication control unit 112. Select the appropriate communication device. The selection criterion storage unit 122 stores selection criteria for the device selection unit 110 to select an appropriate communication device. A specific example of the selection criteria stored in the selection criteria storage unit 122 will be described later. The device selection unit 110 notifies the selected communication device of an incoming call via the local communication control unit 112 and starts communication for the incoming call notification. At the same time, the device selection unit 110 can notify the local communication control unit 112 and disconnect the communication device other than the selected communication device.

  In addition, when selecting a communication device, the device selection unit 110 performs a process of causing the notification unit 114 to notify the selected communication device. Thereby, the user can know which communication device has been selected.

  When the incoming call detection unit 104 detects an incoming call and there is no communication device connected to the local communication control unit 112, the local communication control unit 112 determines that the device storage unit 120 is based on an instruction from the device information acquisition unit 108. A connection can be established with a wireless communication device registered in. Thereafter, the local communication control unit 112 acquires device information of each communication device based on an instruction from the device information acquisition unit 108.

  Further, the device information acquisition unit 108 is connected to the mobile phone 100 around the mobile phone 100 at that time, even if the communication device is not registered in the device storage unit 120 via the local communication control unit 112. Possible wireless communication devices can be detected. In this case, the local communication control unit 112 can establish a connection with the detected wireless communication device based on an instruction from the device information acquisition unit 108.

  In addition, the device information acquisition unit 108 detects a wireless communication device that is around the mobile phone 100 at that time and can be connected to the mobile phone 100 regardless of the presence or absence of a communication device connected to the local communication control unit 112. You can also. The local communication control unit 112 can establish a connection with the detected wireless communication device based on an instruction from the device information acquisition unit 108. Thereafter, the local communication control unit 112 acquires device information of each communication device based on an instruction from the device information acquisition unit 108.

  The communication system according to the present embodiment can be configured such that a message format used for device information transmission / reception, a parameter range, and the like are defined in advance between the mobile phone 100 and each communication device. When each communication device receives a parameterized device information transmission request from the mobile phone 100, each communication device can return a corresponding parameter value. Thereby, the mobile phone 100 can acquire device information of each communication device.

FIG. 2 is a block diagram illustrating an example of the configuration of the local wireless communication device 300.
The local wireless communication device 300 includes a remaining battery level detection unit 310, an available function detection unit 312, a local device information acquisition unit 314, a local communication control unit 316, and a local device information storage unit 318.

  The own device information storage unit 318 stores device information of the local wireless communication device 300. For example, the own device information storage unit 318 stores the communication function of the local wireless communication device 300 and the transmission speed of the local wireless communication device 300 in each communication function in association with each other. The own apparatus information storage unit 318 can also store whether each function of the local wireless communication device 300 is usable.

  The usable function detecting unit 312 refers to the own device information storage unit 318 and the setting information, and detects a communication function that is set to be usable at that time among communication functions of the local wireless communication device 300. . For example, even if the local wireless communication device 300 has a plurality of communication functions, there is a possibility that any one of the communication functions cannot be used due to user settings or the like. Also, any communication function may be in use. The usable function detecting unit 312 can detect a usable communication function of the local wireless communication device 300 periodically or when a change is set, and can store the detected communication function in the own device information storage unit 318. When the local communication control unit 316 receives a device information transmission request from the mobile phone 100, the own device information acquisition unit 314 can read available communication functions from the own device information storage unit 318.

  In another example, the usable function detection unit 312 sets the usable function among the functions of the local wireless communication device 300 when the local communication control unit 316 receives a device information transmission request from the mobile phone 100. It is also possible to detect the communication function being performed and notify the own device information acquisition unit 314 of the detected communication function.

  The remaining battery level detection unit 310 detects the remaining battery level of the local wireless communication device 300. The battery remaining amount detection unit 310 notifies the own device information acquisition unit 314 of the detected result.

  The own device information acquisition unit 314 reads the transmission speed corresponding to the usable communication function from the own device information storage unit 318. When the local communication control unit 316 receives a device information transmission request from the mobile phone 100, the local device information acquisition unit 314 returns the device information of the local device at that time as a response via the local communication control unit 316. To 100. When the device information acquisition unit 314 receives a device information acquisition request from the mobile phone 100, the device information acquisition unit 314 can detect the radio wave intensity with the mobile phone 100 based on the received data. In this case, the own apparatus information acquisition unit 314 can also transmit the radio wave intensity as device information to the mobile phone 100. In another example, on the mobile phone 100 side, for example, the device information acquisition unit 108 can detect the radio wave intensity with each communication device based on a response from each communication device.

  Although the local wireless communication device 300 has been described as an example above, the local wireless communication device 302 and the wired communication device 304 can be configured to have the same function. Note that the wired communication device 304 is connected to the mobile phone 100 by wire, so the radio wave intensity is not detected.

FIG. 3 is a flowchart showing a processing procedure of mobile phone 100 in the present embodiment.
When the communication unit 102 receives an incoming call notification from the mobile phone network 200 and the incoming call detection unit 104 detects an incoming call (YES in S100), the incoming call detection unit 104 receives the incoming call information acquisition unit 106 and the device information acquisition unit 108. Notify that has been detected. The incoming call information acquisition unit 106 acquires incoming call information from the incoming call notification received by the communication unit 102 (S102). The device information acquisition unit 108 detects whether there is a communication device currently connected to the mobile phone 100 via the local communication control unit 112 (S104). If there is a connected communication device (YES in S104), the device information acquisition unit 108 sends the transmission speed, the remaining battery capacity, the usable communication function from the connected communication device via the local communication control unit 112, Device information indicating the state of each communication device such as radio field intensity in the case of wireless is acquired (S108).

  Based on the incoming information acquired by the incoming information acquisition unit 106, the device information acquired by the device information acquisition unit 108, and the connection management information held by the local communication control unit 112, the device selection unit 110 Then, a communication device suitable for communication for the incoming call notification is selected (S110).

  Thereafter, the device selection unit 110 notifies the communication device selected via the local communication control unit 112 of an incoming call, and starts communication for the incoming call notification with the communication device (S112).

  Subsequently, the local communication control unit 112 determines whether there is a connected communication device other than the communication device that has made the incoming call notification in step S112 (S114). If there are other connected communication devices (YES in S114), the local communication control unit 112 disconnects the communication devices (S116). Thereby, in the mobile phone 100, it is not necessary to manage other connected communication devices, and the processing load of the own device can be reduced. In addition, when a communication device cannot connect to a plurality of devices at the same time, the communication device can accept a connection with another apparatus by disconnecting the connection with the mobile phone 100. Thereafter, the process is terminated. On the other hand, if there is no other connected communication device in step S114 (NO in S114), the process ends.

  In step S104, when there is no connected communication device (NO in S104), the device information acquisition unit 108 refers to the device storage unit 120 and registers in the device storage unit 120 based on an instruction from the device information acquisition unit 108. The connection processing with the communication device that has been performed is performed (S118). When the connection process with the communication device is performed (YES in S120), the process proceeds to step S108. On the other hand, when connection processing cannot be performed with any communication device (NO in S120), connection impossible processing is performed (S122). Specifically, a response such as “Currently unable to connect” is sent to the calling terminal, or a notification such as “Cannot connect, please check” is given to the user of the mobile phone 100. Can do.

FIG. 4 is a flowchart illustrating an example of a procedure in which the device selection unit 110 selects an appropriate communication device in accordance with the selection criteria stored in the selection criteria storage unit 122.
First, the device selection unit 110 is a communication device that can use the same communication function as the communication function included in the incoming information based on the incoming information acquired by the incoming information acquisition unit 106 and the device information acquired by the device information acquisition unit 108. It is determined whether or not there is (S200). If there are communication devices that can use the same communication function (YES in S200), those communication devices are selected. Subsequently, the device selection unit 110 determines whether there is a communication device connected to the mobile phone 100 by wire in the selected communication device (S202). When there are communication devices connected by wire (YES in S202), those communication devices are selected. When a wired communication device is connected to the mobile phone 100, there is a high possibility that the user wants to use the wired communication device preferentially. Therefore, here, an example is shown in which when a wired communication device is connected, the wired communication device is preferentially selected. However, the present invention is not limited to this, and the selection criterion of the selection criterion storage unit 122 may be changed so that the wireless communication device is preferentially selected.

  Subsequently, the device selection unit 110 determines whether or not the battery level of the selected communication device is sufficient (S204). If there are communication devices with sufficient remaining battery power (YES in S204), those communication devices are selected. Thereafter, the device selection unit 110 selects a communication device that performs notification of an incoming call based on the transmission speed from the selected communication devices (S206). Specifically, the device selection unit 110 preferentially selects a communication device having the same transmission speed as the transmission speed included in the incoming call information. If there is no communication device having the same transmission speed, the device selection unit 110 preferentially selects a communication device having a high transmission speed. The process ends as described above.

  If the remaining battery level of the selected communication device is not sufficient in step S204 (NO in S204), the device selection unit 110 determines whether there is a wireless communication device selected in step S200 (S208). When there is no wireless communication device (NO in S208), the device selection unit 110 notifies the user through the notification unit 114 that, for example, the remaining battery level is low and there is a possibility that communication may be cut off halfway. (S210), the process proceeds to step S206, and one of the communication devices selected in step S202 is selected. At this time, the device selection unit 110 can also preferentially select the communication device with the largest remaining battery capacity regardless of the transmission speed of the communication device.

  In step S202, if there is no wired-connected communication device (NO in S202) or if there is a wirelessly connected communication device in step S208 (YES in S208), the wirelessly connected communication device is selected. Subsequently, the device selection unit 110 determines whether or not the battery level of the selected communication device is sufficient (S212). Here, if there are communication devices with sufficient remaining battery power (YES in S212), those communication devices are selected. Thereafter, the device selection unit 110 selects a communication device that performs notification of incoming calls based on the transmission speed and the radio wave intensity from the selected communication devices (S214). Specifically, the device selection unit 110 preferentially selects a communication device having the same transmission speed as the transmission speed included in the incoming call information. If there is no communication device having the same transmission speed, the device selection unit 110 preferentially selects a communication device having a high transmission speed. Further, the device selection unit 110 can preferentially select a communication device having a high radio wave intensity for communication devices having the same transmission speed. The process ends as described above.

  If the remaining battery level of the selected communication device is not sufficient in step S212 (NO in S212), the device selection unit 110, for example, has a low battery level via the notification unit 114, and communication is cut off halfway. In addition to notifying the user that there is a possibility (S216), the process proceeds to step S214, and one of the selected communication devices is selected. At this time, the device selection unit 110 can also preferentially select the communication device with the most remaining battery power regardless of the transmission speed and radio wave intensity of the communication device.

  In step S200, when there is no communication device that can use the same communication function (NO in S200), the device selection unit 110 performs a communication disable process (S218). Specifically, a response such as “Currently unable to connect” is sent to the calling terminal, or a notification such as “Cannot connect, please check” is given to the user of the mobile phone 100. Can do.

Next, a specific example will be described with reference to FIGS.
Assume that the device information of each communication device acquired by the device information acquisition unit 108 in step S108 (FIG. 3) is as follows.
(1) Local wireless communication device 300: usable communication function = voice communication, transmission speed = 64 Kbps, remaining battery level = high, radio wave intensity = strong,
(2) Local wireless communication device 302: Usable communication function = voice communication and moving image data communication, transmission speed = 64 Kbps during voice communication, 64 Kbps or 128 Kbps during moving image data communication, battery remaining amount = high, radio wave intensity = weak,
(3) Wired communication device 304: usable communication function = voice communication and packet data communication function, transmission speed = 64 Kbps for voice communication, maximum 2 Mbps for packet data communication, and remaining battery charge = many.

  Also, for example, it is assumed that the incoming information acquired by the incoming information acquisition unit 106 in step S102 (FIG. 3) is communication function = moving image data communication and transmission speed = 128 Kbps. In this case, according to the procedure shown in FIG. 4, the local wireless communication device 302 having the function of moving image data communication and having a sufficient remaining battery level is selected.

  Also, for example, it is assumed that the incoming call information acquired by the incoming call information acquisition unit 106 in step S102 is communication function = voice communication and transmission speed = 64 Kbps. In this case, a wired communication device 304 that has a voice communication function, is wired, and has a sufficient remaining battery level is selected.

  As described above, the mobile communication device and the communication system including the same according to the present embodiment have the following effects.

  Based on the device information of each communication device at the time when the mobile phone 100 receives the incoming call notification from the mobile phone network 200, a communication device that starts communication for the incoming call notification from the mobile phone network 200 is selected. Therefore, it is possible to select an appropriate communication device corresponding to the dynamic state change of each communication device.

  Further, based on the incoming call information of the incoming call notification received from the mobile phone network 200, a communication device that starts communication for the incoming call notification from the mobile phone network 200 is selected. Therefore, an appropriate communication device can be selected for the incoming call notification.

  Further, based on connection management information between the mobile phone 100 and the communication device, a communication device that starts communication for an incoming notification from the mobile phone network 200 is selected. Accordingly, an appropriate communication device can be selected in consideration of the user's intention.

  As described above, since an appropriate communication device is automatically selected, the user has to make settings in advance, or the user has to select a communication device after receiving an incoming call notification from the mobile phone network 200. It can be omitted.

  Each component of the cellular phone and the local wireless communication device shown in FIGS. 1 and 2 is realized by any combination of hardware and software. These figures show functional unit blocks, not hardware unit configurations.

  The embodiments of the present invention have been described above with reference to the drawings, but these are exemplifications of the present invention, and various configurations other than those described above can be adopted.

  With reference to FIG. 4, an example of a procedure in which the device selection unit selects an appropriate communication device is shown. For example, when there are a plurality of communication devices that satisfy the selection criteria stored in the selection criteria storage unit 122, the mobile phone 100 notifies all of those communication devices of the incoming call, and notifies the communication device that first responded of the incoming call. Can be made to communicate. In this case, the connection with other communication devices can be disconnected.

  Further, when the mobile communication terminal has a multi-call function, when the second call is received, the same processing as that for the first call can be performed.
