The bus 10 transfers data between the control unit 11 , the storage unit 12 , and the display unit 17 .

Next, each component of the power supply control unit 112 will be described in detail.

The presence information acquisition control unit 112 a acquires the presence information shown in FIG. 3A received by the communication unit 13 from the presence server 7 , and stores it in the presence information storage area 121 . Thereby, when the user views the presentation information, it is possible to confirm the communication status of the wireless communication unit included in the electronic device on the communication network within the presentation communication system PS. In addition, the mobile phone device 1 may receive from the presence server 7 only the presence information of the electronic device whose presence PR has been changed. In such a case, the presence information acquisition control unit 112a may rewrite only the changed portion of the presence information already stored in the presence information storage area 121 based on the received presence information.

Also, when the presence information is acquired, the presence information acquisition control unit 112a notifies the presence specifying unit 112b that the presence information has been acquired.

The presence determination unit 112b compares the presence information in FIG. 3A stored in the presence information storage area 121 with the presence monitoring target information in FIG. The electronic device of the surveillance object.

The power supply determination unit 112c determines, based on the presentation PR of the electronic device determined to be the monitoring target by the presentation determination unit 112b, the power supply information of the communication unit 13 stored in the power supply state storage area 123, and the information of the communication unit 13 stored in the communication state storage area 124. The communication state information determines whether to continue or stop the power supply to the first wireless communication unit 131 or the second wireless communication unit 132 .

Furthermore, the power supply determination unit 112c instructs the power controller 15a to control the power supply from the battery 15b to the first wireless communication unit 131 and the second wireless communication unit 132 based on the determination result.

The forwarding control unit 112d requests the call control server 5 to forward the incoming call to the mobile phone device 1 to another electronic device according to the forwarding destination information.

Next, the operation of each component of the presentation communication system PS when the mobile phone device 1 controls the second wireless communication unit 132 from ON to OFF in order to suppress power consumption of the battery 15b will be described with reference to the flowcharts of FIGS. 4A to 4C .

Furthermore, as a premise, it is assumed that when the power of the mobile phone device 1 is turned on, both the first wireless communication unit 131 and the second wireless communication unit 132 are powered and start up in an online state.

When the user presses the power button of the mobile phone device 1 to turn on the power of the mobile phone device 1, the processing shown in the flowcharts of FIGS. 4A to 4C starts. In addition, in FIGS. 4A to 4C , the description will focus on the operations related to the second wireless communication unit 132 among the operations of the mobile phone device 1 .

When the user performs a power-on operation (step A10 in FIG. 4A ), the power supply control unit 112 supplies power for operation to the second wireless communication unit 132 (step A11 ). In addition, the power supply control unit 112 also supplies power for operation to the first wireless communication unit 131 in the same manner.

The second wireless communication unit 132 transmits a session establishment request to the call control server 5 via the second base station 4a (step A12). The call control server 5 receives the session establishment request (step A50), and executes session establishment processing (step A51). As a result, a session is established between the second wireless communication unit 132 and the call control server 5 (step A13).

In addition, the second wireless communication unit 132 requests the location registration server 6 to register the location information via the call control server 5 when transmitting the session establishment request. For this process, the call control server 5 requests the location registration server 6 to register the location information of the second wireless communication unit 132 of the mobile phone device 1 (step A52). The location registration server 6 receives the registration request of the location information (step A60), and executes the registration process of the location information (step A61).

Furthermore, when transmitting a session establishment request, the second wireless communication unit 132 requests the presence server 7 to register presence information via the call control server 5 . For this processing, the call control server 5 requests the presence server 7 to register the presence information of the second wireless communication unit 132 of the mobile phone device 1 (step A53).

The presence server 7 receives the presence information registration request (step A70), and executes the presence information registration process (step A71). The presence server 7 recognizes that the second wireless communication unit 132 of the mobile phone device 1 is online (active) based on the request from the call control server 5 in step A53.

After the second wireless communication unit 132 requests the registration of the location information and the registration of the presence information, it waits to receive a wireless signal from another electronic device (step A14 ). Also, the first wireless communication unit 131 establishes a session with the call control server 5 like the second wireless communication unit 133 . Then, the position information and presence information of the first wireless communication unit 131 are registered in the position registration server 6 and the presence server 7 .

It is assumed that the user performs a power-on operation of the mobile phone device 2 after the second wireless communication unit 132 has shifted to the receiving standby state. When the user performs a power-on operation (step A20 in FIG. 4B ), power for operation is supplied to the wireless communication unit of the mobile phone device 2 .

At this time, the mobile phone device 2 (the wireless communication unit of the mobile phone device 2 ) transmits a session establishment request to the call control server 5 via the second base station 4 a (step A21 ). The call control server 5 receives the session establishment request (step A54), and executes session establishment processing (step A55). As a result, a session is established between the mobile phone device 2 and the call control server 5 (step A22).

Furthermore, when the mobile phone device 2 transmits a session establishment request, the call control server 5 requests the location registration server 6 to register the location information, and requests the presence server 7 to register the presence information. For this processing, the call control server 5 requests the location registration server 6 to register the location information of the mobile phone device 2 (step A56), and requests the presence server 7 to register the presence information of the mobile phone device 2 (step A57). Based on the request from the call control server 5 in step A57, the presence server 7 recognizes that the wireless communication unit included in the mobile phone device 2 is online (active).

When the session is established, the mobile phone device 2 shifts to the reception standby state (step A23), and waits until the next processing is requested.

The location registration server 6 receives the registration request of the location information (step A62), and executes the registration process of the location information (step A63).

The presence server 7 receives the presence information registration request (step A72), and executes the presence information registration process (step A73).

The presence server 7 notifies the mobile phone device 1 of the presence information of the registered mobile phone device 2 through the second wireless communication system 4, that is, the presence information indicating that the mobile phone device 2 has moved online (step A74 of FIG. 4C ).

Here, the reason why the presence server 7 notifies the mobile phone device 1 of the presence information via the second wireless communication system 4 is that the second wireless communication unit 132 communicating via the second wireless communication system 4 recognizes that it is online (active). In addition, the presence server 7 may notify the mobile phone device 1 of the presence information via the first wireless communication system 3 when recognizing that the first wireless communication unit 131 is online (active).

The second wireless communication unit 132 receives presence information indicating that the mobile phone device 2 registered in the presence monitoring target information is online (step A15 ).

The mobile phone device 1 analyzes the received presentation information (step A16). As a result of the analysis, the mobile phone device 1 recognizes that the mobile phone device 2 that communicates through the second wireless communication system 4 like the second wireless communication unit 132 is online. Therefore, the mobile phone device 1 executes the processes of steps A17 and A18 for turning off the power of the second wireless communication unit 132.

First, the mobile phone device 1 requests the call control server 5 to forward the call to the second wireless communication unit 132 from another electronic device to the online mobile phone device 2 (step A17). At this time, the mobile phone device 1 may use either the first wireless communication unit 131 or the second wireless communication unit 132 to request incoming call forwarding.

The call control server 5 requests the number collation database server 8 to set incoming call forwarding according to the request from the mobile phone device 1 (step A58). The number collation database server 8 receives the setting request of incoming call forwarding (step A80), and sets incoming call forwarding (step A81). The call control server 5 refers to the information set in the number collation database server 8 when executing incoming call forwarding.

In the mobile phone device 1, after the forwarding control unit 112d requests the call control server 5 to forward the call, the power supply control unit 112 stops the power supply to the second wireless communication unit 132 (step A18).

As a result, the second wireless communication unit 132 enters the power-off state until power is supplied next time.

The processing contents of steps A16 to A18 will be described later in detail with reference to the flowchart of FIG. 6 .

In addition, if the electronic device on the originating side has a function to make a call after confirming the PR of the electronic device on the receiving side, the user on the originating side may select an online electronic device from the electronic devices of the communication partner to make a call. , Therefore, the processing for the forwarding of incoming letters in steps A17, A58, A80 and A81 does not have to be carried out. In addition, in such a case, the mobile phone device 1 does not have to include the forwarding destination information storage area 125 and the forwarding control unit 112d.

However, in the case where the forwarding destination storage area 125 and the forwarding control unit 112d are provided in the mobile phone device 1, even if the electronic device of the communication destination is online, the incoming letter is forwarded to other electronic devices. The user can place a call without paying attention to the presentation PR of the electronic device of the communication destination.

Next, the operation of each component of the presentation communication system PS when the mobile phone device 1 controls the second wireless communication unit 132 from off to on will be described with reference to the flowcharts of FIGS. 5A to 5C .

And, as a premise, it is assumed that the operating states of the mobile phone device 1 and the mobile phone device 2 at the start of the processing shown in the flowcharts of FIGS. 5A to 5C are the states at the end of the processing shown in the flowcharts of FIGS. 4A to 4C . That is, power is supplied to the first wireless communication unit 131 , and power supply to the second wireless communication unit 132 is stopped.

In addition, the power of the mobile phone device 2 is turned on to be in a receiving standby state.

In this state, when the user performs a power-off operation of the mobile phone device 2 (step B20 in FIG. 5A ), the processing shown in the flowcharts of FIGS. 5A to 5C starts.

When the user performs a power-off operation, the mobile phone device 2 sends a session disconnection request to the call control server 5 through the second base station 4a (step B21). The call control server 5 receives the session disconnection request (step B50), and executes session disconnection processing (step B51). As a result, the session established between the mobile phone device 2 and the call control server 5 is disconnected (step B22). If the session is cut off, the mobile phone device 2 turns off the power (step B23), and waits until the next processing is requested. Specifically, the mobile phone device stops power supply to the wireless communication unit, and waits until the power is turned on.

Also, when transmitting a session disconnection request, the mobile phone device 2 requests the location registration server 6 to delete the registration of the location information through the call control server 5 and requests the presence server 7 to change the presence information. For this processing, the call control server 5 requests the location registration server 6 to delete the registration of the location information of the mobile phone device 2 (step B52), and requests the presence server 7 to change the presence information of the mobile phone device 2 (step B53).

The location registration server 6 receives the registration deletion request of the location information (step B60), and executes the registration deletion process of the location information (step B61). The presence server 7 receives the change request of the presence information (step B70), and executes the change process of the presence information (step B71). Thereby, the presence server 7 recognizes that the mobile phone device 2 has moved offline.

The presence server 7 notifies the first wireless communication unit 131 of the mobile phone device 1 of the presence information indicating that the mobile phone device 2 has gone offline via the call control server 5 and the first wireless communication system 3 (step B72 in FIG. 5B ).

The reason for notifying the presence information to the first wireless communication unit 131 is that the presence server 7 receives the first wireless communication of the mobile phone device 1 from the call control server 5 when a session is established between the first wireless communication unit 131 and the call control unit 5 . The registration request of the presence information by the communication unit 131 recognizes that the first wireless communication unit 131 of the mobile phone device 1 is online (active).

Furthermore, when the first wireless communication unit 131 notified of the presence information is in the "intermittent reception" standby state in which the communication channel is interrupted intermittently and waits, the presence information notifying device 3b notifies that the presence information exists, for example Use SMS (ShortMessage Service, short message service) and so on.

The first wireless communication unit 131 of the mobile phone device 1 receives presence information indicating that the mobile phone device 2 registered in the presence monitoring target information is offline (step B10 ).

The portable telephone device 1 analyzes the received presence information (step B11). As a result of the analysis, the mobile phone device 1 recognizes that the mobile phone device 2 , which communicates through the second wireless communication system 4 like the second wireless communication unit 132 , is in an offline state. Therefore, the mobile phone device 1 supplies electric power to the second wireless communication unit 132 in order to activate the communication function of the second wireless communication unit 132 (step B12).

Further, the processing contents of steps B11 and B12 will be described in detail later with reference to the flowchart of FIG. 6 .

The second wireless communication unit 132 transmits a session establishment request to the call control server 5 via the second base station 4a (step B13). The call control server 5 receives the session establishment request (step B54), and executes session establishment processing (step B55). Thus, the second wireless communication unit 132 establishes a session with the call control server 5 (step B14).

Also, when transmitting a session establishment request, the second wireless communication unit 132 requests the location registration server 6 to register the location information and the presence server 7 to register the presence information via the call control server 5 . For this process, the call control server 5 requests the location registration server 6 to register the location information of the second wireless communication unit 132 (step B56), and requests the presence server 7 to register the presence information of the second wireless communication unit 132 (step B57).

The location registration server 6 receives the location information registration request (step B62), and executes the location information registration process of the second wireless communication unit 132 of the mobile phone device 1 (step B61).

The presence server 7 recognizes that the second wireless communication unit 132 of the mobile phone device 1 is online (valid) in accordance with the request from the call control server 5 in step B57. The presence server 7 receives the presence information registration request (step B73), and executes the presence information registration process of the second wireless communication unit 132 of the mobile phone device 1 (step B74).

The mobile phone device 1 requests the call control server 5 to cancel the incoming call forwarding set in the number comparison database server 8 to forward the incoming call to the second wireless communication unit 132 to the mobile phone device 2 (step B15 of FIG. 5C ). . In response to the request from the mobile phone device 1, the call control server 5 requests the number collation database server 8 to release the incoming call forwarding setting (step B58).

The number matching database server 8 receives the call forwarding setting cancellation request (step B80), and cancels the incoming call forwarding setting (step B81).

In this way, while the power of the second wireless communication unit 132 is turned off, if the power of the mobile phone device 2 to which the incoming letter sent to the second wireless communication unit 132 is forwarded is turned off, the second wireless communication unit 132 that should originally receive the incoming letter is turned off. operation, and cancels the incoming call forwarding setting with the mobile phone device 2 as the forwarding destination.

When cancellation of incoming call forwarding is requested, the second wireless communication unit 132 shifts to the reception standby state (step B16), and waits until the next processing is requested.

Further, the contents of steps B11, B12, and B15 in the flowcharts of FIGS. 5A to 5C will be described in detail with reference to the flowchart of FIG. 6 . In addition, the flowchart of FIG. 6 includes not only the processing of steps B11, B12, and B15 in FIGS. 5A to 5C but also the processing of steps A16 to A18 in FIGS. 4A to 4C.

In addition, in FIGS. 4A to 4C and FIGS. 5A to 5C , the mobile phone device 2 is shown as an example of an electronic device that controls and monitors the power supply of the second wireless communication unit 132 . However, the electronic device performing monitoring may be any electronic device capable of communicating via the second wireless communication system 4 exemplified in FIG. 3B as the present monitoring target information. Also, when monitoring a plurality of electronic devices at the same time, power supply to the second wireless communication unit 132 is stopped as shown in FIGS. 4A to 4C when any one of the electronic devices to be monitored comes online. Furthermore, when all electronic devices to be monitored are offline, electric power is supplied to the second wireless communication unit 132 as shown in FIGS. 5A to 5C .

The first wireless communication unit 131 or the second wireless communication unit 132 of the mobile phone device 1 receives the presence information from the presence server 7 via the first wireless communication system 3 or the second wireless communication system 4, thereby starting the process shown in the flowchart of FIG. 6 . power supply control processing.

That is, if the portable telephone device 1 receives presentation information in step A15 of FIG. 4C or step B10 of FIG. 5B , this power supply control process starts. Note that the processing of steps C10 to C18 described later in FIG. 6 corresponds to the processing of step A16 in FIG. 4C and step B11 in FIG. 5B .

If the presence information is received by the first wireless communication unit 131 or the second wireless communication unit 132, the presence information acquisition control unit 112a acquires the received presence information from the first wireless communication unit 131 or the second wireless communication unit 132 (step C10), It is stored in the presentation information storage area 121 (step C12).

Next, the presence information acquisition control unit 112a notifies the presence determination unit 112b that the presence information has been acquired (step C12).

The presence specifying unit 112b refers to the presence monitoring target information stored in the presence monitoring target information storage area 122, and judges whether the presence information of the monitoring target is included in the presence information storage area 121 (step C13). For example, the presence specifying unit 112b determines whether or not the device identifier AI of the monitoring target (replacement electronic device) indicated by the presence monitoring target information shown in FIG. 3B is included in the device identifier AI stored in the presence information storage area 121 . If the presence information of the monitoring target is not included in the presence information storage area 121 ("No" in step C13), the control unit 11 ends the power supply control process and waits until the next presence information is received.

If the presence information of the monitoring object is included in the presence information storage area 121 ("Yes" in step C13), the power supply determination part 112c refers to the power supply state storage area 123 to determine whether the second wireless communication part 132 is supplying power (step C13). C14).

If power is supplied to the second wireless communication unit 132 and the second wireless communication unit 132 is operating ("Yes" in step C14), the power supply determination unit 112c refers to the presence information of the monitoring object in the presence information storage area 121 to determine whether there is Online status monitoring target (step C15). For example, when the presence information storage area 121 includes presence information of a plurality of monitoring objects, the power supply determination unit 112c determines whether there is at least one monitoring object whose presentation PR is "online".

If there is no online monitoring target ("No" in step C15), the control unit 11 ends the power supply control process, and waits until the next presentation information is received.

If there is at least one online monitoring object ("Yes" in step C15), the power supply determination part 112c further refers to the communication state storage area 124 to determine whether the communication state of the second wireless communication part 132 is "in communication" (step C16 ).

If the communication state of the second wireless communication unit 132 is in communication (“Yes” in step C16), the power supply determination unit 112c determines whether the first wireless communication unit 131 or the second wireless communication unit 132 has received new presentation information (step C16). C17).

When no new presence information has been received ("No" in step C17), the control unit 11 transfers the process to step C16, and the power supply determination unit 112c waits until the communication status of the second wireless communication unit 132 is not in communication. When new presentation information is received (YES in step C17), the control unit 11 shifts the processing to step C10, and the power supply control unit 112 re-executes the power supply control process from the beginning based on the new presentation information. .

If the communication state of the second wireless communication unit 132 is not in communication (“No” in step C16), the forwarding control unit 112d sends a call to the caller in order to forward the incoming letter to the second wireless communication unit 132 from other devices to the monitoring object of the online status. The control server 5 requests incoming letter forwarding (step A17). For example, when there are a plurality of online monitoring objects, the forwarding control unit 112d requests the call control server 5 to forward the incoming call in order to forward the incoming call to one of them.

After the transfer control unit 112d requests the call control server 5 to transfer the incoming call, the power supply determination unit 112c stops the power supply to the second wireless communication unit 132 (step A18). As a result, the second wireless communication unit 132 enters the power-off state until power is supplied and activated next time.

On the other hand, when it is determined in step C14 that power is not supplied to the second wireless communication unit 132 and the second wireless communication unit 132 is not operating ("No" in step C14), the power supply determination unit 112c Referring to the presence information of the monitoring object in the presence information storage area 121, it is judged whether there is an online monitoring object (step C18).

If there is at least one online monitoring object ("Yes" in step C18), since it is not necessary to activate the second wireless communication unit 132, the control unit 11 ends the power supply control process and waits until the next presentation information is received. .

If there is no online monitoring object ("No" in step C18), since the forwarding from the second wireless communication unit 132 does not reach the monitoring object, in order to make it reach the second wireless communication unit 132, it is necessary to make the second The wireless communication unit 132 operates.

At this time, in order to start the power supply to the second wireless communication unit 132, the power supply determination unit 112c outputs an instruction signal instructing the power supply to the second wireless communication unit 132 to the power controller 15a. The power controller 15a receives the instruction signal, and controls the battery 15b to supply electric power to the second wireless communication unit 132 (step B12).

The forwarding control unit 112D requests the call control server 5 to release the incoming call forwarding set in the number collation database server 8 for forwarding the incoming call addressed to the second wireless communication unit 132 to the mobile phone device 2 (step B15).

The mobile phone device 1 is on standby until the next presentation information is received.

Furthermore, in step C16, it may be further determined whether or not the reception state of the wireless signal by the first wireless communication unit 131 is good. This is because, when the receiving state of the communication unit 131 is not good, the first wireless communication unit 132 cannot receive the presence information by the first wireless communication unit 131 after the first wireless communication unit 132 transitions to the power-off state. In this case, when it is determined that the communication state of the first wireless communication unit 131 is not good, the power supply determination unit 112c does not stop the power supply to the second wireless communication unit 132 until the communication state of the first wireless communication unit 131 becomes good. Just supply it.

In addition, even if the reception state of the wireless signal of the first wireless communication unit 131 is good at the time of executing the process of step C16, after the second wireless communication unit 132 is shifted to the power-off state, the first wireless communication unit 131’s The reception status of wireless signals may also become poor. In order to solve this problem, when it is determined that the communication state of the first wireless communication unit 131 is not good, the power supply to the second wireless communication unit 132 may be started immediately. Accordingly, it is possible to avoid a state where neither the first wireless communication unit 131 nor the second wireless communication unit 132 can receive a wireless signal.

Furthermore, when the second wireless communication unit 132 is in the power-off state, when the user uses the second wireless communication unit 132 to perform communication, the power supply to the second wireless communication unit 132 may be immediately started.

At this time, in order to detect the start of communication using the second wireless communication unit 132 , it is only necessary to detect, for example, that the user inputs an instruction to execute communication using the second wireless communication unit 132 from the operation unit 16 . Specifically, the operation unit receives input of instruction information to start communication with the second wireless communication unit 132 in response to the user's operation. When the power supply control unit 112 stops the power supply to the second wireless communication unit 132, when instruction information is input to the operation unit 16, the power supply to the second wireless communication unit 132 is resumed. In addition, in order to detect the start of communication using the second wireless communication unit 132 , the storage unit 12 may have an application associated with the second wireless communication unit 132 in advance and detect that the application is activated by the user. Thereby, the user can communicate using the second wireless communication unit when desired.

As described above, the mobile phone device 1 according to the first embodiment includes the first wireless communication unit 131 that communicates through the first wireless communication system 3 and the second wireless communication unit 132 that communicates through the second wireless communication system 4 . The mobile phone device 1 makes an electronic device (replacement electronic device) that communicates via the second wireless communication system 4 instead of the second wireless communication unit 132 a monitoring target. The presence information acquisition control unit 112 a acquires presence information indicating the communication state of the monitoring target from the presence server 7 . The power supply determination unit 112c determines whether or not the monitoring target is in an online state where communication is possible based on the acquired presence information. If the power supply determination unit 112c determines that the monitoring object is online, the power consumed by the second wireless communication unit 132 is suppressed.

Therefore, according to the mobile phone device 1 according to the first embodiment, when the electronic device to be monitored is online, the electronic device can communicate instead of the second wireless communication unit 132, and the consumption of the electronic device by the second wireless communication unit 132 can be suppressed. electricity. Thus, according to the first embodiment, the power consumption of the entire mobile phone device 1 can be suppressed.

In addition, in the first embodiment, when the presentation information acquisition control unit 112a cannot suppress the power consumption of the second wireless communication unit 132, it uses one of the first wireless communication system 2 and the second wireless communication system 4, from The presence server 7 acquires presence information. On the other hand, when the power consumption of the second wireless communication unit 132 is suppressed, the presence information acquisition control unit 112 a acquires the presence information from the presence server 7 via the first wireless communication system 3 . Then, if the power supply determination unit 112c acquires the presence information indicating that the monitoring target is not online while the power consumption of the second wireless communication unit 132 is being suppressed, the suppression of the power consumption of the second wireless communication unit 132 is released.

Therefore, according to the mobile phone device 1 according to the first embodiment, when the monitoring object transitions to a communication-incapable state, by restoring the power consumption of the second wireless communication unit 132, at least the monitoring object and the second wireless communication unit 132 While one can be communicated, power consumption can be suppressed.

Furthermore, in the first embodiment, the presence monitoring target information storage area 122 stores presence monitoring target information indicating the device identifier AI of the monitoring target. The presence information acquisition control unit 112a receives from the presence server 7 the device identifier AI for identifying the electronic device on the communication network and the device identifier specified by the device identifier through one of the first wireless communication system 3 and the second wireless communication system 4 The presentation PR of the electronic device is linked and obtained. The presence specifying unit 112 b judges whether or not the device identifier AI acquired by the presence information acquisition control unit 112 a is stored in the presence monitoring target information storage area 122 . The presence PR associated with the device identifier AI determined by the presence specifying unit 112 b and stored in the presence monitoring target information area 122 becomes presence information to be monitored.

Therefore, according to the mobile phone device 1 according to the first embodiment, it is possible to appropriately acquire the presence information of the monitoring target.

In addition, in the first embodiment, the power supply determination unit 112c executes power supply to the second wireless communication unit 132 when the monitoring target is not online. Also, the power supply determination unit 112c stops the power supply to the second wireless communication unit 132 when the monitoring object is online.

Therefore, according to the mobile phone device 1 according to the first embodiment, the power consumption of the mobile phone device 1 can be suppressed by controlling the power supply to the second wireless communication unit 132 .

Furthermore, in the first embodiment, the first wireless communication unit 131 is a wide area wireless communication unit that communicates via the first wireless communication system 3 that is a wide area wireless communication network. The second wireless communication unit 132 is a local wireless communication unit that communicates via the second wireless communication system 4 that is a local wireless communication network. The local wireless communication network has a base station with a narrower radio wave reach than the base station of the wide area wireless communication network.

Therefore, according to the mobile phone device 1 according to the first embodiment, the power consumed by the local wireless communication unit can be suppressed.

In addition, in the first embodiment, when the power supply judging unit 112c judges that the monitoring object is online, the forwarding control unit 112d sends a forwarding request to the number comparison database server 8 as a forwarding server through the call control server 5, and the forwarding request uses The information transmitted to the second wireless communication unit 132 through the second wireless communication system 4 is forwarded to the monitoring target.

Therefore, according to the first embodiment, the call control server 5 of the reference number collation database server 8 automatically executes forwarding, so the sender can communicate without looking for an electronic device to communicate instead of the second wireless communication unit 132 .

(second embodiment)

Next, a second embodiment of the present invention will be described with reference to FIGS. 1 , 7 and 8 .

In the second embodiment, the intermittent reception interval, which indicates the timing interval at which the communication function of the wireless communication unit operates while waiting, is changed to reduce the amount of data accumulated in the first wireless communication unit 131 and the second wireless communication unit 132 for operation. An example of power consumption in the battery 15b. In addition, in FIGS. 7 and 8 , the same reference numerals are assigned to the same components as those shown in FIGS. 2 and 6 .

First, the circuit configuration of the mobile phone device 1 according to the second embodiment will be described with reference to FIG. 7 .

In the second embodiment, the control unit 11 includes an intermittent reception interval determination unit 112 e and a timer unit 113 .

The intermittent reception interval determination unit 112e determines the first wireless communication unit 131 and the second wireless communication unit 131 by referring to the determination result of the presence determination unit 112b, the intermittent reception interval information stored in the storage unit 12, and the communication status of the communication unit 13 in the communication status storage area 124. Intervals in which the communication function of the wireless communication unit 132 is intermittently operated. Furthermore, the intermittent reception interval determination unit 112 e stores the determined intermittent reception interval in the intermittent reception interval storage area 126 .

Here, the intermittent reception interval refers to an interval indicating that power is supplied from the battery 15b to the first wireless communication unit 131 and the second wireless communication unit 132 in order to operate the communication functions of the first wireless communication unit 131 and the second wireless communication unit 132. A specified time interval for a timed interval.

In addition, the intermittent reception interval is synchronized with the time slot TS defined by the wireless signal received by the first wireless communication unit 131 and the second wireless communication unit 132 while waiting. This radio signal contains the information to be received at the time interval of each time slot TS.

The timer unit 113 counts the elapsed time from the end time of the reception process performed just now, and detects that the elapsed time has reached the intermittent reception interval.

In the intermittent reception interval storage area 126 of the second embodiment, a normal reception interval T1 and a preset power-saving reception interval T2 having a value larger than the normal reception interval T1 are stored.

Furthermore, the first reception interval flag F1 and the second reception interval flag F2 are currently stored in the intermittent reception interval storage area 126. The above-mentioned first reception interval flag F1 indicates that the first wireless communication unit 131 Which of the intermittent reception intervals in the reception interval T2 is operated, the second reception interval flag F2 indicates which of the normal reception interval T1 and the power-saving reception interval T2 the second wireless communication unit 132 operates on.

The communication control unit 111 refers to the first reception interval flag F1 and the second reception interval flag F2, and controls the first wireless communication unit 131 and the second wireless communication unit 131 according to the intermittent reception interval indicated by the first reception interval flag F1 and the second reception interval flag F2. communication by the communication unit 132 .

In addition, the power controller 15 a also continues or stops power supply to the first wireless communication unit 131 and the second wireless communication unit 132 according to the intermittent reception interval stored in the intermittent reception interval storage area 126 .

Next, the intermittent reception interval control process in which the power supply control unit 112 of FIG. 7 controls the intermittent reception interval of the second wireless communication unit 132 based on the presence information received by the mobile phone device 1 will be described with reference to the flowchart of FIG. 8 .

The intermittent reception interval control process shown in the flow chart of FIG. Server 7 starts by receiving presentation information.

If the first wireless communication unit 131 or the second wireless communication unit 132 receives the presence information, the presence information acquisition control unit 112a acquires the received presence information from the first wireless communication unit 131 or the second wireless communication unit 132 (step C10), and stored in the presentation information storage area 121 (step C11).

Next, the presence information acquisition control unit 112a notifies the presence information determination unit 112b that the presence information has been acquired (step C12).

The presence specifying unit 112b refers to the presence monitoring target information stored in the presence monitoring target information storage area 122, and determines whether the presence information of the monitoring target is included in the presence information storage area 121 (step C13). If the presence information of the monitoring target is not included in the presence information storage area 121 ("No" in step C13), the control unit 11 ends the intermittent reception interval control process and waits until the next presence information is received.

If the presence information of the monitoring object is contained in the presence information storage area 121 ("Yes" in step C13), the intermittent reception interval judging section 112e refers to the second reception interval flag F2 stored in the intermittent reception interval storage area 126, and judges that Which of the normal reception interval T1 and the power-saving reception interval T2 is the intermittent reception interval in which the communication function of the second wireless communication unit 132 operates (step D10 ).

If the second wireless communication unit 132 operates based on the normal reception interval T1 ("Yes" in step D10), the intermittent reception interval judging section 112e refers to the presence information of the monitoring object in the presence information storage area 121 to determine whether there is an online monitoring object (step C15).

If there is no online monitoring object ("No" in step C15), the control unit 11 ends the intermittent reception interval control process, and waits until the next presence information is received.

If there is at least one online monitoring object ("Yes" in step C15), the intermittent reception interval judging section 112e further refers to the communication state storage area 124, and judges whether the communication state of the second wireless communication section 132 is "in communication" (step C16).

If the communication state of the second wireless communication unit 132 is in communication (“Yes” in step C16), the intermittent reception interval determination unit 112e determines whether the first wireless communication unit 131 or the second wireless communication unit 132 has received new presence information ( Step C17).

When no new presence information has been received ("No" in step C17), the control unit 11 transfers the process to step C16, and the intermittent reception interval determination unit 112e waits until the communication state of the second wireless communication unit 132 is not in communication. . When new presence information is received (YES in step C17), control unit 11 moves the process to step C10, and power supply control unit 112 restarts the intermittent reception interval control process based on the new presence information.

If the communication state of the second wireless communication unit 132 is not in communication (“No” in step C16), the forwarding control unit 112d transmits the incoming letter to the second wireless communication unit 132 from other electronic devices to the monitoring object of the online status. The call control server 5 requests incoming call forwarding (step A17).

After the forwarding control unit 112d requests the call control server 5 to forward the incoming call, the intermittent reception interval determination unit 112e rewrites the content indicated by the second reception interval flag F2 in order to increase the intermittent reception interval for communication by the second wireless communication unit 132 as Power saving reception interval T2 (step D11). The communication control unit 111 refers to the rewritten second reception interval flag F2, and operates the second wireless communication unit 132 at the power-saving reception interval T2.

On the other hand, in step D10, even if it is determined that the second wireless communication unit 132 operates based on the power-saving reception interval T2 ("No" in step D10), the intermittent reception interval determination unit 112e Referring to the presence information of the monitoring object in the presence information storage area 121, it is judged whether there is an online monitoring object (step C18).

If there is at least one monitoring object in an online state ("Yes" in step C18), since it is not necessary to make the second wireless communication unit 132 work with the usual receiving interval T1, the control unit 11 ends the intermittent receiving interval control process, and under receiving One remains on standby until a message is presented.

If there is no monitoring object in the online state ("No" in step C18), since the forwarding from the second wireless communication part 132 does not reach the monitoring object, in order to receive the incoming letter reliably at the second wireless communication part 132, intermittent reception interval The determination unit 112e operates the second wireless communication unit 132 based on the normal reception interval T1.

Therefore, the intermittent reception interval determination unit 112e rewrites the content indicated by the second reception interval flag F2 to the normal reception interval T1 in order to shorten the intermittent reception interval during which the second wireless communication unit 132 communicates (step D12). The communication control unit 111 refers to the rewritten second reception interval flag F2 to operate the second wireless communication unit 132 at the normal reception interval T1.

The forwarding control unit 112d requests the call control server 5 to release the incoming call forwarding set in the number collation database server 8 for forwarding the incoming call addressed to the second wireless communication unit 132 to the mobile phone device 2 (step B15).

The mobile phone device 1 is on standby until the next presentation information is received.

As described above, in the mobile phone device 1 according to the second embodiment, when the monitoring object is not online, the intermittent reception interval determination unit 112e sets the intermittent reception interval of the second wireless communication unit 132 to the normal interval as the reference interval. Receive interval T1. Also, when the monitoring object is online, the intermittent reception interval determination unit 112e sets the intermittent reception interval of the second wireless communication unit 132 to the power-saving reception interval T2 which is an interval longer than the reference interval. When the second wireless communication unit 132 operates at the power-saving reception interval T2, it consumes less power than when it operates at the normal reception interval T1.

Therefore, according to the mobile phone device 1 according to the second embodiment, the power consumption of the mobile phone device 1 can be suppressed by controlling the intermittent reception interval of the second wireless communication unit 132 .

In addition, in the second embodiment, the normal reception interval T1 and the power-saving reception interval T2 are preset fixed values, but they may be changed by the user. In this case, if the user wants to further reduce power consumption, the user can increase the value of the power-saving reception interval T2.
