4 and 5 are sequence diagrams illustrating a control flow during a call executed in the communication system 1. FIG.
The portable terminal 10 is paired with the electronic device 20 that is in close proximity (step S1). The call control unit 111 of the mobile terminal 10 may permit pairing when the electronic device 20 comes within close range of short-range wireless communication, or pairing according to the operation of the user U or the like May be allowed.

  Next, the call control unit 111 determines whether to start a call (step S2). This call may be started when the mobile terminal 10 accepts an incoming call and responds to the incoming call, or may be started when the mobile terminal 10 transmits and the mobile terminal 30 responds to the incoming call. Good.

  When the call is started (step S2; YES), the call control unit 111 specifies the distance between the mobile terminal 10 and the electronic device 20 (step S3). The call control unit 111 identifies the distance from the electronic device 20 based on the received electric field strength of the radio wave related to the short-range wireless communication received by the short-range wireless communication unit 141. In step S3, the distance value may be actually calculated or may not be calculated. In step S3, at least whether or not the distance between the mobile terminal 10 and the electronic device 20 is equal to or greater than (less than) a predetermined distance may be specified.

  Next, the call control unit 111 determines whether the distance between the identified mobile terminal 10 and the electronic device 20 is equal to or greater than a predetermined distance (step S4). The predetermined distance is a predetermined distance. The said distance is determined based on the distance which can perform the hands-free call using the electronic device 20, for example, when the user U exists in the position of the portable terminal 10. FIG.

  When it is determined “YES” in step S4, that is, when it is determined that the distance between the mobile terminal 10 and the electronic device 20 is equal to or greater than the predetermined distance, the call control unit 111 sets the flag F1 to “0” (step S5). ). That is, the call control unit 111 puts the mobile terminal 10 into a state for performing a handset call. As shown in the upper part of FIG. 6, when the distance between the mobile terminal 10 and the electronic device 20 is relatively large, if the user U is at the position of the mobile terminal 10, a hands-free call using the electronic device 20 is performed. It is impossible or difficult. In such a case, the possibility that the user U is going to make a hands-free call using the electronic device 20 is low, and it is assumed that the user U is going to make a handset call.

The control when performing a handset call will be described.
When the voice (transmission voice) of the user U is input via the voice input / output unit 151 (step S6), the call control unit 111 transmits the transmission voice data indicating the transmission voice via the network communication unit 142. To the network NW (step S7). When the call control unit 111 receives received voice data from the network NW via the network communication unit 142 (step S8), the call control unit 111 outputs the received voice indicated by the received voice data via the voice input / output unit 151. (Step S9).
In the mobile terminal 10, the processes in steps S <b> 6 to S <b> 9 are sequentially performed during a period in which communication for a call is performed.

  If “NO” is determined in the step S4, that is, if the distance between the mobile terminal 10 and the electronic device 20 is determined to be less than the predetermined distance, the call control unit 111 sets the flag F1 to “1” (step S10). ). That is, the call control unit 111 is in a state of performing a hands-free call. As shown in the lower part of FIG. 6, when the distance between the mobile terminal 10 and the electronic device 20 is relatively small, if there is a user U at the position of the mobile terminal 10, a hands-free call using the electronic device 20 is performed. be able to. In such a case, it is assumed that there is a possibility that the user U is going to make a hands-free call without having to hold the mobile terminal 10 in the hand during the call.

  When the flag F1 is set to “1”, the call control unit 111 requests the electronic device 20 to turn on the call function via the short-range wireless communication unit 141 (step S11). When the call control unit 211 receives the request via the short-range wireless communication unit 241 in the electronic device 20, the call control unit 211 sets the flag F2 to “1” (step S12). That is, the call control unit 211 turns on the call function of the electronic device 20 and puts it in a state of performing a hands-free call.

The control when performing a hands-free call will be described.
When the voice (transmission voice) of the user U is input via the voice input / output unit 251 (step S13), the call control unit 211 converts the transmission voice data indicating the transmission voice into the short-range wireless communication unit 241. Is transmitted to the mobile terminal 10 (step S14). In the mobile terminal 10, when the call control unit 111 receives the transmission voice data via the short-range wireless communication unit 141, the call control unit 111 transmits the transmission voice data to the network NW (step S15). When the call control unit 111 receives received voice data from the network NW via the network communication unit 142 (step S16), the call control unit 111 sends the received voice data to the electronic device 20 via the short-range wireless communication unit 141. Transmit (step S17). In the electronic device 20, when the call control unit 211 receives the received voice data via the short-range wireless communication unit 241, the call control unit 211 outputs the received voice indicated by the received voice data via the voice input / output unit 251 (step S18). ).
In the mobile terminal 10 and the electronic device 20, the processes in steps S <b> 13 to S <b> 18 are sequentially performed during a period in which communication for a call is performed.

The call control unit 111 of the mobile terminal 10 sequentially specifies the distance between the mobile terminal 10 and the electronic device 20 even during the communication for the call, and determines whether the distance is equal to or greater than the predetermined distance. Also good. Then, the call control unit 111 switches between a state in which a handset call is performed and a state in which a handsfree call is performed according to whether the distance is equal to or greater than a predetermined distance. When switching from a hands-free call state to a handset call state, the call control unit 111 requests the electronic device 20 via the short-range wireless communication unit 141 to turn off the call function. When the call control unit 211 of the electronic device 20 receives this request via the short-range wireless communication unit 241, the call control unit 211 sets the flag F2 to “0” and turns off the call function.
As a result, the user U who wants to make a hands-free call only needs to approach the electronic device 20 while holding the mobile terminal 10. Further, when the distance between the user U holding the mobile terminal 10 and the electronic device 20 is large and it is difficult for voice to reach the electronic device 20, a handset call is performed.

  Thus, the user U does not need to explicitly instruct whether to perform a hands-free call or a handset call. In addition, the call function is switched on / off by a method suitable for the situation of the user U ascertained from the distance between the mobile terminal 10 and the electronic device 20. Therefore, a call can be made with a device in accordance with the intention of the user U according to the use state of the mobile terminal 10 having the call function and the electronic device 20.

[Second Embodiment]
In the second embodiment, the mobile terminal 10 is in a state of a call based on a different condition in addition to the distance between the mobile terminal 10 and the electronic device 20 during a call for a call. Control to switch between. As control examples, the following (Control Example 1) to (Control Example 5) will be described. In the following description, the same elements as those of the first embodiment described above are denoted by the same reference numerals as those of the first embodiment described above.

(Control example 1)
FIG. 7 is a sequence diagram showing a flow of control (control example 1) regarding on / off switching of the call function executed in the communication system 1. It is assumed that a hands-free call has been performed before the start of the following operation.
The call control unit 111 of the mobile terminal 10 determines whether an operation for instructing the start of a handset call has been received via the input / output device 15 (step S21). If “NO” is determined in the step S21, the call control unit 111 continues the hands-free call.

  If “YES” is determined in the step S21, the call control unit 111 starts the handset call by setting the flag F1 to “0” (step S22). Furthermore, the call control unit 111 requests the electronic device 20 via the short-range wireless communication unit 141 to turn off the call function (step S23). When the call control unit 211 of the electronic device 20 receives this request via the short-range wireless communication unit 241, the call control unit 211 sets the flag F2 to “0” and turns off the call function (step S24). As described above, when the mobile terminal 10 accepts a predetermined operation while a hands-free call is being performed, it is assumed that the user U has indicated that he / she wants to make a call on the mobile terminal 10, and the handset call is made from the hands-free call. Switch to.

During the period in which the handset call is performed, the call control unit 111 determines whether or not the mobile terminal 10 has been in a non-operation state for a predetermined time (step S25). The no-operation state refers to a state where a state in which the mobile terminal 10 does not accept an operation from the user U continues for a predetermined time. If “YES” is determined in the step S25, the call control unit 111 determines whether the electronic device 20 is being paired (step S27). If “YES” is determined in the step S27, the call control unit 111 sets the flag F1 to “1” (step S28). The call control unit 111 requests the electronic device 20 to turn on the call function via the short-range wireless communication unit 141 (step S29). In the electronic device 20, when the call control unit 211 receives this request via the short-range wireless communication unit 241, the call control unit 211 sets the flag F2 to “1” (step S30). That is, the call control unit 211 puts the electronic device 20 into a state where a hands-free call is performed.
When the mobile terminal 10 is in an operation-free state for a predetermined time, there is a possibility that the user U is not in a state of holding the mobile terminal. In such a case, it is considered that it is easier for the user U to make a hands-free call.

If “NO” is determined in the step S25, the call control unit 111 determines whether or not the mobile terminal 10 has transitioned to the locked state (step S26). The locked state refers to a state where use of some functions of the mobile terminal 10 is restricted. For example, the screen display of the mobile terminal 10 is not performed in the locked state. In such a case, there is a possibility that the user U is not in a state of holding the mobile terminal 10 in his / her hand. Therefore, it may be convenient for the user U to make a hands-free call. Therefore, when it is determined “YES” in step S26, the call control unit 111 proceeds to step S27 to determine whether pairing is being performed. If pairing is being performed (step S27; YES), the flag F1 is set. It is set to “1” (step S28). Then, the call control unit 111 requests the electronic device 20 to turn on the call function via the short-range wireless communication unit 141 (step S29). In the electronic device 20, when the call control unit 211 receives this request via the short-range wireless communication unit 241, the call control unit 211 sets the flag F2 to “1” and sets a state of performing a hands-free call (step S30).
If “NO” is determined in steps S26 and S27, the handset call continues.

  According to (Control Example 1) described above, it is possible to switch between a state in which a hands-free call is performed and a state in which a handset call is performed according to the operation of the user U with respect to the mobile terminal 10 or the state of the mobile terminal 10.

(Control example 2)
FIG. 8 is a sequence diagram showing a flow of control (control example 2) related to switching on / off of a call function executed in the communication system 1. It is assumed that a hands-free call has been performed before the start of the following operation.

  In the mobile terminal 10, when the call control unit 111 receives the transmission voice data from the electronic device 20, the call control unit 111 specifies the level of the transmission voice based on the transmission voice data (steps S31 and S32). This level may be a sound pressure level of a frequency belonging to a predetermined frequency band (for example, a voice band), or may be a volume. This level is an indicator of whether or not the voice of the user U has sufficiently reached the electronic device 20.

  The call control unit 111 determines whether or not the specified voice level is less than a threshold (step S33). If the call control unit 111 determines that the voice level of the user U is equal to or higher than the threshold (step S33; NO), the call control unit 111 continues the hands-free call. In this case, the user U is close to the electronic device 20 to the extent that a hands-free call is possible, and a sufficient level of transmitted voice can be secured.

  If the call control unit 111 determines that the level of the specified voice is less than the threshold (step S33; YES), the call control unit 111 sets the flag F1 to “0” to start the handset call (step S34). For example, it is assumed that “YES” is determined in step S33 when a state where the sound level is less than the threshold value continues for a predetermined time.

  Furthermore, the call control unit 111 requests the electronic device 20 via the short-range wireless communication unit 141 to turn off the call function (step S35). When the call control unit 211 of the electronic device 20 receives this request via the short-range wireless communication unit 241, it sets the flag F2 to “0” and turns off the call function (step S36). Thus, when the level of the sound input to the electronic device 20 becomes less than the threshold, the user U may move away from the electronic device 20 and it may be difficult to perform a hands-free call. Moreover, in such a case, it is guessed that the user U is going to make a handset call. Therefore, the call control unit 111 switches from the hands-free call to the handset call.

  In the above-described (control example 2), the hands-free call and the handset call can be switched from the user U voice level without an explicit instruction from the user U. The portable terminal 10 may switch from a handset call to a hands-free call when the audio level is equal to or higher than a threshold during pairing with the electronic device 20.

(Control example 3)
FIG. 9 is a sequence diagram illustrating a flow of control (control example 3) regarding on / off switching of the call function executed in the communication system 1. It is assumed that a handset call is in progress before the following operation starts. Further, it is assumed that the mobile terminal 10 and the electronic device 20 are being paired.

  The call control unit 111 specifies the distance between the mobile terminal 10 and the electronic device 20 (step S41). Next, the call control unit 111 determines whether the distance between the mobile terminal 10 and the electronic device 20 is equal to or greater than a predetermined distance (step S42). If "YES" is determined in the step S42, the call control unit 111 returns to the step S41 and continues the handset call as it is.

  If “NO” is determined in step S42, the call control unit 111 acquires data indicating the orientation or / and displacement of the mobile terminal 10 from the sensor unit 152, and based on this data, the orientation or / And a displacement is specified (step S43). Then, the call control unit 111 determines whether the mobile terminal 10 is in a stationary state (step S44). The stationary state refers to a state in which the mobile terminal 10 is stationary for a predetermined time. If “NO” is determined in the step S44, the call control unit 111 returns to the step S41 and continues the handset call as it is.

  If it is determined as “YES” in step S44, the call control unit 111 sets the flag F1 to “1” (step S45). Then, the call control unit 111 requests the electronic device 20 to turn on the call function via the short-range wireless communication unit 141 (step S46). When the call control unit 211 receives the request via the short-range wireless communication unit 241 in the electronic device 20, the call control unit 211 sets the flag F2 to “1” and puts the electronic device 20 into a state of performing a hands-free call (Step S1). S47).

In the case where a handset call is being performed, when the mobile terminal 10 is held by the user U's hand, there is some possibility of a change or displacement of the posture, and there is a low possibility that the mobile terminal 10 will be in a stationary state. On the other hand, when the mobile terminal 10 is in a stationary state, it is assumed that the user U has moved away from the hand, such as placing the mobile terminal 10 on a desk. In this case, it is inferred that the user U wants to switch to a hands-free call. Therefore, the mobile terminal 10 switches from the handset call to the hands-free call. The portable terminal 10 may switch to a handset call when there is a change in posture and / or displacement after switching to a hands-free call, or when the portable terminal 10 is not stationary.
According to the control example 3 described above, it is possible to switch between a hands-free call and a handset call depending on whether or not the mobile terminal 10 is in a stationary state.

(Control example 4)
FIG. 10 is a sequence diagram illustrating a flow of control (control example 4) related to switching on / off of a call function executed in the communication system 1. It is assumed that a handset call is in progress before the following operation starts. Further, it is assumed that the mobile terminal 10 and the electronic device 20 are being paired.

  The call control unit 111 specifies the distance between the mobile terminal 10 and the electronic device 20 (step S51). Next, the call control unit 111 determines whether the distance between the mobile terminal 10 and the electronic device 20 is equal to or greater than a predetermined distance (step S52). If "YES" is determined in the step S52, the call control unit 111 returns to the step S51 and continues the handset call as it is.

  If “NO” is determined in the step S52, the call control unit 111 acquires the surrounding environment data from the electronic device 20 via the short-range wireless communication unit 141 (step S53). The surrounding environment data is data indicating the surrounding environment of the electronic device 20. As the surrounding environment data, there is data indicating whether or not another person exists around the electronic device 20. The surrounding environment data includes, for example, data indicating a noise level at the location of the electronic device 20 or data measured by a human sensor (for example, an infrared sensor).

  Then, the call control unit 111 determines whether there is another person around the electronic device 20 based on the data indicating the surrounding environment (step S54). For example, when the noise level is equal to or higher than the threshold value or when the presence of a person is detected by the human sensor, the call control unit 111 determines “YES” in step S54. In this case, the call control unit 111 returns to step S51 and continues the handset call as it is. This is because if there is another person around the electronic device 20, the content of the call may be heard or the user U may have difficulty in making a call.

If it is determined as “NO” in step S54, the call control unit 111 sets the flag F1 to “1” (step S55). Then, the call control unit 111 requests the electronic device 20 to turn on the call function via the short-range wireless communication unit 141 (step S56). In the electronic device 20, when the call control unit 211 receives this request via the short-range wireless communication unit 241, the call control unit 211 sets the flag F <b> 2 to “1” and puts the electronic device 20 into a state of performing a hands-free call ( Step S57).
According to (Control Example 4) described above, it is possible to switch between a state in which a hands-free call is performed and a state in which a handset call is performed in accordance with the surrounding state of the electronic device 20.

(Control example 5)
FIG. 11 is a sequence diagram illustrating a flow of control (control example 5) related to on / off switching of a call function executed in the communication system 1. It is assumed that a handset call is in progress before the following operation starts. Further, it is assumed that the mobile terminal 10 and the electronic device 20 are being paired.

  The call control unit 111 identifies the distance between the mobile terminal 10 and the electronic device 20 (step S61). Next, the call control unit 111 determines whether the distance between the mobile terminal 10 and the electronic device 20 is equal to or greater than a predetermined distance (step S62). If “YES” is determined in the step S62, the call control unit 111 returns to the step S61 and continues the handset call as it is.

  If “NO” is determined in the step S62, the call control unit 111 acquires usage status data from the electronic device 20 via the short-range wireless communication unit 141 (step S63). The usage status data is data indicating the usage status of the electronic device 20. The usage status data includes data indicating whether or not the electronic device 20 has already been used for a hands-free call, or data indicating whether or not the electronic device 20 has already been used for another purpose.

  Then, the call control unit 111 determines whether or not the electronic device 20 is being used by another person (step S64). If the call control unit 111 determines that the electronic device 20 is being used by another person (step S64; YES), the call control unit 111 returns to step S61 and continues the handset call. This is because if the electronic device 20 is being used by another person, there is a disadvantage that the hands-free call cannot be used or that the other person cannot use the electronic device 20 by performing the hands-free call.

If it is determined as “NO” in step S64, the call control unit 111 sets the flag F1 to “1” (step S65). Then, the call control unit 111 requests the electronic device 20 to turn on the call function via the short-range wireless communication unit 141 (step S66). In the electronic device 20, when the call control unit 211 receives this request via the short-range wireless communication unit 241, the call control unit 211 sets the flag F2 to “1” and enters a state of performing a hands-free call (step S67).
According to (Control Example 5) described above, it is possible to switch between a state in which a hands-free call is performed and a state in which a handset call is performed according to the usage state of the electronic device 20.
In the communication system 1, all of the controls (Control Example 1) to (Control Example 5) described above may be performed, or only a part of the controls may be performed.
