Description

The technology of the present disclosure relates to a call control technology for a mobile terminal device such as a mobile phone.

  With the spread of mobile terminal devices such as smartphones, a single user often owns and uses two or more mobile terminal devices. In addition, one user may use two or more telephone lines and a plurality of telephone numbers. When a plurality of portable terminal devices are used, a specific portable terminal device is used during work, and another private portable terminal device is used for holidays or private use.

As described above, regarding the use of a plurality of mobile terminal devices, a plurality of mobile terminal devices are grouped and an effective terminal is determined according to the terminal usage status sent from each mobile terminal device. It is known to notify (for example, Patent Document 1). In addition, it is known that a separate telephone number is used for a mobile terminal device to establish an independent call link with another mobile terminal device to make a two-party call or another party call (for example, Patent Document 2). .

  By the way, if a user who uses two or more lines, has a plurality of telephone numbers, and uses a plurality of mobile terminal devices, calls all incoming calls, all the mobile terminal devices Need to carry. Carrying a plurality of portable terminal devices lacks convenience.

  In order to unify incoming mobile terminal devices, it is only necessary to transfer the mobile terminal device to be carried. However, this setting requires setting of a transfer number by a user operation, and usually the transfer destination is static and only one setting.

  Moreover, even if the transfer setting is made, a call cannot be made when the mobile terminal device is not turned on or in a situation where the incoming call cannot be made, such as outside the calling area. A call cannot be made unless the mobile terminal device with the number registered at the transfer destination is at hand of the user. In other words, even if the transfer destination mobile terminal device is specified, a call cannot be made unless it is carried, and a call cannot be made by an incoming call at a position away from the user.

[First Embodiment]

  FIG. 1 shows a portable terminal device according to the first embodiment. This portable terminal device (hereinafter referred to as “terminal”) 2-1 receives an incoming call from the terminal 4 on the transmission side via the base station 5, and at the time of this incoming call, a plurality of terminals such as the terminals 2-2 and 2-3 are connected. In response, a confirmation message is sent.

  The terminal 2-1 includes a communication unit 6 and a call control unit 8 as an example. Similarly, the terminals 2-2 and 2-3 may include the communication unit 6 and the call control unit 8, respectively. The communication unit 6 transmits confirmation messages to the plurality of terminals 2-2 and 2-3, or receives response messages for the confirmation messages from the terminals 2-2 and 2-3.

  The call control unit 8 uses the other terminals 2-2 and 2-3 included in the response message returned in response to the confirmation message transmitted to the plurality of terminals 2-2 and 2-3 during the incoming call. For example, at least one terminal 2-3 is determined using the evaluation information regarding. And while responding to the incoming call of the terminal 4, a three-way call is set between the terminal 4 of the response destination and the determined other terminal 2-3.

  FIG. 2 shows a call control processing procedure of the terminals 2-1, 2-2, and 2-3. This processing procedure is an example of a processing procedure for call control to be executed by a computer.

  In this processing procedure, the terminal 2-1 transmits confirmation messages to the plurality of terminals 2-2 and 2-3 (S1).

  The terminal 2-1 receives a response message to the confirmation message from the terminals 2-2 and 2-3 (S2).

  During the incoming call, at least one other information is evaluated using the evaluation information on the usage status of the other terminals 2-2 and 2-3 included in the response message to the confirmation message transmitted to the plurality of terminals 2-2 and 2-3. The terminal, for example, the terminal 2-3 is determined (S3).

  Thereby, while responding to the incoming call from the terminal 4, a three-way call is set between the terminal 2-1 as a response destination and the determined other terminal 2-3 (S4).

  In this processing procedure, the terminal 2-3 is set as the transfer destination, but the terminal 2-2 may be set as the transfer destination, and the number of terminals may be four or more.

<Effect of the first embodiment>

  (1) When receiving a call, the degree of freedom of the transfer destination terminal can be increased.

  (2) When receiving an incoming call, the transfer destination terminal is automatically determined, and a user-friendly terminal can be selected as the transfer destination.

[Second Embodiment]

  FIG. 3 shows an example of call control of the mobile terminal device according to the second embodiment. In FIG. 3, the same parts as those in FIG.

  In this configuration example, there are a terminal 4 that is a mobile terminal device on the transmission side, and terminals 2-1, 2-2, and 2-3 that are a plurality of mobile terminal devices on the reception side. Each of the terminals 2-1, 2-2, 2-3 is an example of a mobile terminal device of the present disclosure.

  Each terminal 2-1, 2-2, 2-3 belongs to the public network 10. The terminal 4 may belong to the public line network 10. The terminal 4 is connected to the company A line management system 12-1, for example. Each terminal 2-1, 2-2, 2-3 on the receiving side belongs to one incoming call group 14. In this incoming call group 14, the terminals 2-1 and 2-2 belong to the line of the company A base station 5-1, and the company A base station 5-1 is managed by the company A line management system 12-1. . In the incoming call group 14, the terminal 2-3 belongs to the line of the B company base station 5-2, and this B company base station 5-2 is managed by the B company line management system 12-2. Therefore, the terminals 2-1, 2-2, and 2-3 can be connected to each other via a telephone line, an SMS (Short Message Service) line, and a packet line, and can make a call. The SMS line is a known service that can transmit and receive short text messages between portable terminal devices.

  FIG. 4 shows an outline of processing executed by the terminals 4, 2-1, 2-2, 2-3.

  It is assumed that the terminal 4 transmits to the terminal 2-1 (S101). The terminal 2-1 transmits an evaluation value request to all terminals belonging to the incoming call group 14 of the terminal 2-1, in this case, the terminal 2-2 and the terminal 2-3 (S102). This evaluation value request is an example of the confirmation message described above. The “evaluation value” is a value calculated from the location information of the terminals 2-1, 2-2, 2-3, the touch panel operation history of each terminal 2-1, 2-2, 2-3, etc. This is preferable terminal selection information. For transmission of the evaluation value request, for example, an SMS line or a packet line may be used as another communication medium that does not interfere with the incoming state.

  All the terminals belonging to the same incoming call group 14 that received the evaluation value request transmit an evaluation value response to the transmission source (S103). In this example, since an evaluation value request is issued from the terminal 2-1, an evaluation value response is transmitted from the terminals 2-2 and 2-3 belonging to the same incoming call group 14 to the terminal 2-1. Is done. That is, each terminal 2-2, 2-3 transmits its evaluation value to the terminal 2-1. The evaluation value response is an example of a response message for the above-described confirmation message.

  The terminal 2-1 that has received the evaluation value response compares the evaluation value of its own terminal with the evaluation values received from the terminals 2-2 and 2-3 (S104).

  As a result of this comparison, a multi-party call is made to the terminal having the highest evaluation value (S105). In this case, if the evaluation value of the terminal 2-3 is the highest, the terminal 2-1 makes a multi-party call to the terminal 2-3. Thereby, a three-way call is performed between the terminal 4 and the terminals 2-1 and 2-3. If a multi-party call is made but there is no response within a certain period of time, a multi-party call is made to the terminal with the next highest evaluation value (S106).

  Then, the process of S106 is repeated until a call is started at any of the terminals, and the multi-party call transmission is terminated when there is no response from all of the terminals belonging to the incoming call group 14 (S107).

  In the above process, even if an evaluation value request is issued from the terminal 2-1, if there is no evaluation value response within a certain time, there is no evaluation value for a terminal that does not make an evaluation value response.

  If the terminal 2-1 responds by a user operation during such processing, this processing is immediately terminated, and a call on the terminal 2-1 may be started regardless of the evaluation value.

  During a multi-party call transmission, when a response is made by a user operation by any of the terminals 2-1, 2-2, and 2-3, the multi-party call transmission process may be immediately terminated.

  For example, during a three-party call with the terminal 2-3 other than the terminal 2-1, the terminal 2-1 can protect privacy by automatically turning off the microphone and the speaker.

  As described above, in the multi-party call transmission, for example, when there is no response from the terminal 2-3 for a certain period of time, a multi-party call is made to the terminal with the next highest evaluation value. It is only necessary to make a multi-party call by transferring to a higher destination.

  The evaluation value is lower than that of the own terminal, in this example, the terminal 2-1. For example, whether or not to make a multi-party call to the terminal 2-2 is set from a setting menu or the like. It is good also as a setting which does not perform person call transmission. Alternatively, a multi-party call may be attempted to all terminals and a multi-party call may be performed.

  FIG. 5A illustrates a hardware configuration example of the mobile terminal device 2 used for the terminals 2-1, 2-2, and 2-3.

  The mobile terminal device 2 includes a processor 18, a storage unit 20, a communication unit 22, a GPS (Global Positioning System) communication unit 24, a display unit 26, an input unit 28, and a voice input / output unit 30.

The forwarding destination setting information 40-2 includes group information 42, terminal information 44, number information 46, and evaluation value information 48. The group information 42 is the incoming call group 14 grouped by the telephone number of the terminal. A plurality of terminals 2-1, 2-2, 2-3,... Are registered in the terminal information 44. The number information 46 stores different telephone numbers xxx, yyy, xxx,... For each of the terminals 2-1, 2-2, 2-3,. The evaluation value information 48 stores evaluation values N1, N2, N3,... For each terminal belonging to each incoming call group. The size of N1, N2, N3,... Is, for example, N3> N2>.

In this incoming call group terminal list 40-3, terminal information 44 and number information 46 representing terminals belonging to a specific incoming call group, for example, incoming call group 14, are stored for each terminal. In this case, terminal information 44 and number information 46 for identifying the own terminal and other terminals 2-2 and 2-3 are stored in the terminal 2-1.

<Evaluation Value Comparison List 40-4>

The position information 40-5 stores terminal information 44, registered position information 52, current position information 54, and position information 56 n minutes before. The registered position information 52, the current position information 54, and the position information 56 n minutes before are stored for each terminal in the terminal information 44. The registered position information 52 is information representing a registered position such as home. The current position information 54 is information representing the current position of the terminal that is moving.

The operation history 40-6 may store information representing the operation of the touch panel, for example. The operation count information 58 may store the operation count specified by the operation time information 60. The operation time information 60 may store the operated time or a specific time width from the time.

<Call control processing>

  FIG. 8 shows a processing procedure for call control. This processing procedure shows processing when a terminal 4 arrives at a terminal 2-1 belonging to the incoming call group 14. An incoming call is received from the terminal 4 to the terminal 2-1 (S201). The terminal 2-1 determines whether or not there is an incoming call response for a certain time (S202). If there is an incoming call response within a certain time (NO in S202), a normal call is made (S203).

  If there is no incoming response for a predetermined time (YES in S202), an evaluation value request is transmitted from the terminal 2-1 to the terminals belonging to the incoming call group 14 (S204). This evaluation value request is transmitted to the terminals in the incoming call group terminal list 40-3. In this case, since the terminals 2-1 2-2, and 2-3 exist in the incoming call group terminal list 40-3, the terminal 2-1 makes an evaluation value request to the terminals 2-2 and 2-3. . This evaluation value request is made by communication such as SNS or packet.

  In response to this evaluation value request, the terminal 2-1 receives an evaluation value response from the terminals 2-2 and 2-3. This evaluation value response is similarly performed by communication such as SNS or packet.

  The terminal 2-1 that has received the evaluation value response creates the evaluation value comparison list 40-4, compares the received evaluation values, and determines the priority (S206).

  Then, the terminal 2-1 determines whether there is a response from all terminals in the incoming call group 14 (S207). If there is no response from all terminals in the incoming call group 14 in this determination (NO in S207), it is determined whether the response is within the set time (S208).

  Based on such processing, it is determined whether or not the evaluation value of the terminal that has responded within a predetermined time is set to transmit only to the terminal having a high evaluation value (S209). If set in this way (YES in S209), the terminal having an evaluation value lower than that of the own terminal is deleted from the evaluation value comparison list 40-4 (S210).

  A multi-party call is made to a terminal (other than the own terminal) having a high evaluation value in the evaluation value comparison list 40-4 (S211). In this case, if the evaluation value of the terminal 2-3 is high, a multi-party call is made to the terminal 2-3.

  The terminal information that made the multi-party call is deleted from the evaluation value comparison list 40-4 (S212). For example, if a multi-party call is made to the terminal 2-3, the terminal information of the terminal 2-3 is deleted from the evaluation value comparison list 40-4.

  Then, it is determined whether there is a response from the multi-party call within a certain time (S213). In this case, it is determined whether there is a response from the terminal 2-3. If there is no response from the multi-party call destination (NO in S213), the multi-party call destination is changed to a higher evaluation value and the multi-party call is made (S214). In this case, the incoming call group 14 includes the terminal 2-2 in addition to the terminal 2-3, and the multi-party call destination with a high evaluation value is the terminal 2-2. Make a call.

  In this case, if there is a response from the terminal 2-3 (YES in S213), the terminal 4-terminal 2-1-1-terminal 2-3 enters a multi-party call state (S215). If there is no response from the terminal 2-3 and there is a response from the terminal 2-2 (YES in S213), the multi-party call state of the terminal 4-terminal 2-1-1-terminal 2-2 is entered (S215).

  A call disconnection process is received from the terminal 2-3 or the terminal 2-2 in the multi-party call state, and the microphone 36 and the speaker 38 of the terminal 2-1 are set to the OFF state (S216).

  Then, the call is disconnected at the end of the call (S217). With this call control, the microphone 36 and the speaker 38 of the terminal 2-1 are set to return from the OFF state to the ON state (S218), and this process ends.

<Terminal processing of incoming call group>

  FIG. 9 shows terminal-side processing in the incoming call group 14. When the terminal 2-1 receives an incoming call, an evaluation value request is transmitted from the terminal 2-1 to each terminal belonging to the incoming call group 14. Each terminal belonging to the incoming call group 14 receives the evaluation value request (S301). Each terminal that has received this evaluation value request calculates an evaluation value (S302). This evaluation value is calculated by an evaluation value algorithm.

  The evaluation value calculated at each terminal is transmitted from each terminal to the requesting terminal (S303). In this case, if the terminals 2-2 and 2-3 belong to the incoming call group 14, the evaluation values are transmitted from the terminals 2-2 and 2-3 to the terminal 2-1.

  FIG. 10 shows terminal-side processing in the incoming call group 14.

  In this case, in the terminal 2-1, the terminal 2-3 is determined as a terminal having a high evaluation value from the evaluation value comparison list 40-4. Therefore, since the terminal 2-2 has a low priority in the terminal side processing in the incoming call group 14, such processing does not occur.

  In this case, the multi-party call transmission is transmitted from the terminal 2-1 to the terminal 2-3, and arrives at the terminal 2-3 (S401). The terminal 2-3 determines whether to receive a call (S402). When receiving a call (YES in S402), the terminal 2-3 enters a multi-party call state with the terminal 4 and the terminal 2-1 (S403).

  Then, the call is disconnected at the end of the call (S404), and this process ends. This process is also terminated when no answer is received (NO in S402).

<Algorithm for obtaining evaluation value>

  (1) Calculation of evaluation value based on location information

  If the position information is changed with reference to the current position information, the terminal is moving. That is, it can be determined that the user owns the terminal and is moving. If the distance is the same, it can be determined that the user is away from the terminal. In that case, for example, a terminal in a place other than a place registered in advance (home, office, etc.) may be given priority.

  In order to calculate the evaluation value of the terminal using this position information by a computer, for example, the following arithmetic expression may be used.

Evaluation value = distance (absolute value) between the current position information and the position information of the last n minutes ago × constant
... (1)
In this formula (1), a constant may be set to 1.5 when the location is other than home, and 1.0 otherwise. That is, the priority of the area where the user is located is set to a high priority except for the home, and the probability of incoming calls is set high.

  (2) Processing based on operation history

  For example, if the touch panel is being operated as the operation history, it can be determined that the terminal is being used. In this case, in the touch panel operation, if the screen display is OFF, it is assumed that there is no touch panel operation, and in that case, the number of operations is not counted.

  In order to calculate the evaluation value of the terminal using this operation history by a computer, for example, the following arithmetic expression may be used.

            Evaluation value = Number of touch panel operation histories for the last n hours (2)

  (3) Combination processing of location information and operation history

The evaluation values obtained in (1) and (2) may be added to obtain an evaluation value. In this case, the evaluation value is
Evaluation value = Evaluation value of position information + Evaluation value of touch panel operation history (3)
It becomes.

In this case, if the position information is evaluated even when the touch panel is not operated, Equation (3) is
Evaluation value = Evaluation value of position information x Evaluation value of touch panel operation history (4)
It becomes. In this case, the position information is not evaluated if the touch panel is not operated. In this way, the accuracy of the evaluation value can be increased.

  (4) Evaluation value calculation example

  As for the position of each terminal, if the current latitude is lat1, the longitude is lon1, the latitude n minutes ago is lat2, and the latitude is lon2, the distance between the two points may be expressed by equation (5).

Terminal position = (lat1-lat2) ² + (lon1-lon2) ² (5)

  In this case, the value of the square root of the right side of Equation (5) may be used as the terminal position.

  Further, the terminal position may be calculated using the formula of Lambert Andrew instead of the square root value on the right side of Equation (5) or Equation (5).

In this case, for example, if the position information of the home is (lat1, lon1) = 35.582641, 139.641367 and the position information n minutes ago is (lat2, lon2) = 43.0678885, 141.35485, (5) The distance between the two points is
Distance between two points = (lat1-lat2) ² + (lon1-lon2) ²
≒ 18.4 (6)
It becomes.

Therefore, when the evaluation value based on the position information is a constant 1.0
Evaluation value = 1.0 × 18.4 = 18.4 (7)
It becomes.

  (5) Priority judgment by evaluation value

  FIG. 11 shows an evaluation value table 62 when the terminals 2-1 and 2-2 are placed at home and the user is carrying the terminal 2-3. The evaluation value table 62 is stored in the storage unit 20.

  The evaluation value table 62 stores terminal information 44, touch count evaluation value 64, distance evaluation value 66, first combination evaluation value 68, and second combination evaluation value 70.

  The touch count evaluation value 64 stores an evaluation value based on the touch count on the touch panel as an operation history. The distance evaluation value 66 stores the distance evaluation value as the above-described position information. In the combination evaluation value 68, an evaluation value of a combination that is a result of adding the evaluation value in the touch count evaluation value 64 and the evaluation value in the distance evaluation value 66 is stored. In the combination evaluation value 70, an evaluation value of a combination that is a result of multiplying the evaluation value in the touch frequency evaluation value 64 and the evaluation value in the distance evaluation value 66 is stored. Any of such combination evaluation values 68 and 70 may be used.

  In this way, when the operation history is combined with the evaluation value obtained by Expression (7), for example, when the terminals 2-1 and 2-2 are placed at home and the terminal 2-3 is carried, the calling side When terminal 2-1 receives a call from terminal 2-1 and terminal 2-1 becomes a multi-party source, terminal 2-2 has a low priority and terminal 2-3 has a high priority. As a result, a multi-party call with terminal 4 = terminal 2-1 = terminal 2-3 is established.

<Call control sequence>

  FIG. 12 shows an example of a call control sequence during ringback tone ringing.

  In this call control, the terminal 4 makes a call to the terminal 2-1 of the incoming call group 14. Terminals 2-1, 2-2, 2-3 belong to the incoming call group 14.

  The terminal 4 performs a calling process toward the terminal 2-1 (S501), and makes a call to the terminal 2-1 (S502). In the terminal 4, a ringback tone sounds from the call processing (S501) (S503).

  The terminal 2-1 receives a call and a ringback tone sounds (S504). While the ringback tone of the terminal 4 is ringing, the terminal 2-1 performs processing for requesting and receiving an evaluation value with the terminals belonging to the incoming call group 14 (S505). In this process, evaluation value request transmission is performed from the terminal 2-1 to the terminals 2-2 and 2-3 of the incoming call group 14 (S506, S507). In this case, the terminal 2-2 receives the evaluation value request from the terminal 2-1, and calculates the evaluation value (S508). Similarly, the terminal 2-3 receives the evaluation value request from the terminal 2-1, and calculates the evaluation value (S509).

  The terminal 2-2 transmits an evaluation value response for notifying the terminal 2-1 of the calculated evaluation value to the terminal 2-1 (S510). Similarly, the terminal 2-3 transmits an evaluation value response for notifying the terminal 2-1 of the calculated evaluation value to the terminal 2-1 (S511).

  The terminal 2-1 creates the evaluation value comparison list 40-4 and calculates the transfer destination (512).

  In this case, when the terminal 2-3 is determined as a transfer destination by comparing the evaluation values, a multi-party call is transmitted from the terminal 2-1 to the terminal 2-3 (S513). The terminal 2-3 receives a multi-party call from the terminal 2-1, and a ringback tone sounds (S514).

  If the terminal 2-3 is called, a call is established between the terminal 4 and the terminal 2-1 (S515), and a call is established between the terminal 2-1 and the terminal 2-3 (S516). As a result, a multi-party call is established between the three of terminal 4 -terminal 2-1 -terminal 2-3 (S 517).

  The terminal 4 and the terminal 2-3 are busy (S518, S519). In this case, in the terminal 2-1, the microphone 36 and the speaker 38 are turned off (S520). This protects privacy.

  Then, for example, the call is disconnected from the terminal 2-3 (S521), and this is received by the terminal 2-1, and the call is disconnected from the terminal 2-1 to the terminal 4 (S522).

<Effects of Second Embodiment>

  According to the second embodiment, in the case of a user who owns three or more terminals, in the conventional call transfer, the transfer destination is fixed, the setting and change are complicated, and the convenience is low. In the above embodiment, a transfer call can be performed by a multi-party call. When there is an incoming call to a terminal that is not carried, the incoming call can be automatically transferred to another terminal carried by the user at that time, and the substantial transfer is made using the multi-party call service. Can be automated.
