  Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 is a block diagram showing a wireless communication system according to an embodiment of the present invention. The wireless communication system 10 includes a server (communication server) 100, a plurality of wireless base stations 110, 110A, and 110B, and a plurality of mobile communication terminals 200, 200A, and 200B. The communication server 100 is connected to each radio base station 110, 110A, 110B via a communication line 120. The mobile communication terminals 200, 200A, and 200B communicate with other mobile communication terminals by telephone or e-mail via the radio base stations 110, 110A, and 110B that control each area and the communication server 100 connected thereto. Is possible.

  FIG. 2 is a block diagram showing a configuration of the mobile communication terminal 200 of FIG. The other mobile communication terminals 200A and 200B have the same configuration. The mobile communication terminal 200 includes a radio block 201 that communicates with the radio base station 110 via a radio communication line, a call processing block 202 that processes a call, an e-mail processing block 203 that processes an e-mail, a battery And an incoming call restriction data generation block 204 for restricting incoming calls based on the remaining amount of 300.

  The incoming call restriction data generation block 204 includes a remaining battery level measurement unit 205, a remaining battery level profile estimation unit 206, a remaining battery level information transmission unit 207, a priority communication partner notification unit 208, and a storage unit 209. The battery remaining amount measuring unit 205 periodically measures the terminal voltage of the battery 300, obtains the battery remaining amount based on the terminal voltage, and stores it as the battery remaining amount data 211 of the storage unit 209. The remaining battery level profile estimation unit 206 estimates a time-series remaining battery level profile after the current time based on the measured remaining battery level. Also, based on the estimation, for example, a time when the remaining battery level can withstand only one or a predetermined number of calls (hereinafter, this time is referred to as a battery exhaustion time, and this state is referred to as a battery exhaustion) is estimated. . The remaining battery level information transmission unit 207 communicates the remaining battery level information including the remaining battery level profile estimated by the remaining battery level profile estimation unit 206 and the battery exhaustion time via the radio block 201 and the radio base station 110. Send to server 100. Note that the remaining battery information to be transmitted may be only the estimated time of battery exhaustion.

  The priority communication partner notification unit 208 extracts the priority terminal ID list 210 that is a list of the priority communication partner destinations input by the user from the storage unit 209 and transmits the priority terminal ID list 210 to the communication server 100. The priority communication partner is a communication partner that is determined by the user to accept a connection request from the partner even after the battery has run out. For example, in this embodiment, the user designates the mobile communication terminal 200A in FIG. 1 as the priority communication partner.

FIG. 3 is a block diagram showing a configuration of the communication server of FIG. The communication server 100 includes a transmission / reception unit 101, a battery remaining amount information acquisition unit 102, a connection request determination unit 103, a priority information acquisition unit 104, and a storage unit 105. The transmission / reception unit 101 receives necessary information and a connection request from the mobile communication terminals 200, 200A, and 200B via the radio base stations 110, 110A, and 110B. Further, the received connection request is transferred to the corresponding mobile communication terminal 200, 200A, 200B. The battery remaining amount information acquisition unit 102 receives the battery remaining amount information including the battery exhaustion time of the battery 300 in the mobile communication terminal 200 from the mobile communication terminal 200 via the transmission / reception unit 101, and stores the battery remaining information in the storage unit 105. Stored as quantity information 106.

  FIG. 4 exemplifies the battery remaining capacity profile. For example, the mobile communication terminal 200 periodically measures the remaining battery level. The measurement results A1, A2,. . . , A4 is plotted on the time axis. With the slope of the plotted graph, the time of point A5 when the remaining battery level reaches the threshold value, that is, the time t1 when the battery runs out is estimated. The battery remaining power profile estimation unit 206 of the mobile communication terminal 200 stores the battery remaining power profile and the battery exhaustion estimated time plotted as described above as the battery remaining capacity data 211, and the battery remaining capacity profile and the battery exhausted estimated time. Is notified to the communication server 100. The battery remaining amount information acquisition unit 102 of the communication server 100 stores this information in the storage unit 105 as battery remaining amount information 106.

  In the present embodiment, the communication server 100 stores the remaining battery level information 106 including the remaining battery level profile and the estimated battery exhaustion time in the storage unit 105. However, the remaining battery level information 106 can be stored as information including only the battery exhaustion time. Alternatively, instead of the configuration of the above embodiment, the measured value of the remaining battery level may be transmitted to the communication server 100 periodically or intermittently, and the communication server 100 may estimate the battery exhaustion time. The acquisition of the remaining battery level information by the remaining battery level information acquisition unit 102 is executed, for example, every time when the mobile communication terminal 200 newly measures the remaining battery level.

  The priority information acquisition unit 104 receives the priority terminal ID list from the mobile communication terminal 200 and stores it in the storage unit 105 as the priority terminal ID list 107. A call or e-mail connection request with a communication partner having a high priority as a transmission source is identified with reference to the priority terminal ID list 107 and is preferentially sent to the mobile communication terminal 200. More specifically, it is estimated that the remaining battery level of the call or e-mail originating from the priority terminal described in the priority terminal ID list 107 has reached the remaining capacity threshold in the remaining battery level profile of FIG. Is also transmitted to the mobile communication terminal 200 at the time t1, that is, the time t1 when the battery runs out. In addition, the threshold value is provided in two stages, and the first threshold value that the battery level reaches first receives a call or e-mail from a communication partner with a high priority, and the second value that reaches next. The threshold value may be, for example, accepting only an e-mail, or rejecting all connection requests.

  The battery remaining amount information transmitting unit 207 of the mobile communication terminal 200 is configured to transmit A1, A2,. . . As shown by A4, the remaining amount information is transmitted at a constant cycle. However, instead of this, since the remaining battery level is high, the transmission interval is increased when the risk of running out of the battery is low, and the transmission interval is shortened when the remaining battery level is low and the battery is almost exhausted. An interval may be employed. In this case, an accurate battery exhaustion time can be predicted while reducing power consumption due to data transmission.

  FIG. 5 is a flowchart showing processing in the wireless communication system of the above embodiment. In step S <b> 1, the portable communication terminal 200 measures the remaining amount of the battery 300 using the remaining battery amount measurement unit 205 of the portable communication terminal 200. Next, in step S <b> 2, the mobile communication terminal 200 estimates the battery remaining capacity profile and the battery exhaustion time, and transmits them to the communication server 100 as battery remaining capacity information. In step S <b> 3, the communication server 100 stores the received battery remaining amount information as it is, or extracts the battery dead time from this and stores it as the remaining battery amount information 106 in the storage unit 105. Thereafter, in step S4, when the communication server 100 reaches a time before a predetermined time from the estimated battery exhaust time of the mobile communication terminal 200, the communication server 100 starts a transmission source restriction process including a preparation process. In the transmission source restriction process, when there is a connection request from the mobile communication terminals 200A and 200B, the priority terminal ID list 107 is referenced to determine whether or not to permit the connection request. If the transmission source is the mobile communication terminal 200A included in the priority terminal ID list 107, the connection is permitted. If the transmission source is a mobile communication terminal not included in the priority terminal ID list 107, for example, the mobile communication terminal 200B, the connection is rejected. The fact that the connection has been refused is notified to the transmission source mobile communication terminal 200B by a message. In addition, the mobile communication terminal 200 is notified, for example, when the battery has been exhausted, and is displayed in the communication history.

  FIG. 6 shows the detailed process of step S4 in the flowchart of FIG. The communication server 100 starts the preparation process for the transmission source limiting process when the time is a predetermined time before the estimated time of battery exhaustion in the battery remaining amount information 106 stored in the storage unit 105 (step S11). When the mobile communication terminal 200 receives the notification of the start of the transmission source limiting process from the communication server 100, the mobile communication terminal 200 shortens the transmission cycle of the battery remaining amount information (step S12). The mobile communication terminal 200 shortens the battery remaining amount measurement interval according to the transmission interval (step S13). In step S14, the mobile communication terminal 200 determines whether or not the estimated battery dead time has been reached. If the estimated battery dead time has not been reached, the mobile communication terminal 200 measures the remaining battery level at that time. The mobile communication terminal 200 determines whether or not the measured battery remaining amount has reached the remaining amount threshold value (step S15). If it is determined in step S15 that the remaining amount threshold value has not been reached, the process returns to step S13. As shown in FIG. 7, this is a process in the case where the battery has not actually run out even at the estimated time (t2) of the battery running out. The battery remaining capacity profile including the measurement result of the remaining battery level and the estimated battery exhaustion time is transmitted to the communication server 100, and the estimated battery exhaustion time in the communication server 100 is updated according to the content. In this case, for example, the measurement results A11, A12,. . . , A15, the gradient is recalculated, and the time of battery exhaustion is newly estimated.

  If it is determined in step S15 that the remaining battery level is equal to or less than the threshold value, the process proceeds to step S16, and the mobile communication terminal 200 requests the communication server to execute the transmission source restriction process. If it is determined in step S14 that the battery exhaustion scheduled time has been reached, the process proceeds to step S17, where the remaining battery level is measured, and it is determined whether the remaining battery level has reached a threshold value or less. If it is determined in step S17 that the remaining battery level is equal to or less than the threshold value, the mobile communication terminal 200 starts the transmission source restriction process by the communication server 100 and waits as it is (step S18). As shown in FIG. 4, this is a process executed when the estimated time of battery exhaustion substantially coincides with the actual time of battery exhaustion.

  When the mobile communication terminal 200B having a low priority transmits a connection request to the mobile communication terminal 200 to the communication server 100, the communication server 100 refers to the priority terminal ID list 107. The connection request is rejected (step S20). On the other hand, when it is determined in step S17 that the remaining battery level is equal to or greater than the threshold value, the mobile communication terminal 200 notifies the remaining battery level and requests the communication server 100 to cancel the transmission source restriction process. (Step S21). At this time, the battery exhaustion time is updated based on the transmitted remaining battery level.

  When the mobile communication terminal 200B transmits a connection request to the mobile communication terminal 200 to the communication server 100 in step S22, the communication server 100 permits the connection request without referring to the priority terminal ID list 107. (Step S23). Thereafter, a connection request from the mobile communication terminal 200B, for example, a call is transmitted to the mobile communication terminal 200 via the communication server 100, and a call can be made between the two (step S24).

  In the above embodiment, information on the remaining battery level in the mobile communication terminal 200 is stored in the communication server 100 of the wireless communication system 10, and it is determined whether or not to permit a connection request based on the remaining battery level information. . For this reason, it is possible to prevent a situation in which communication cannot be performed due to a battery exhaustion by responding to a connection request that the user does not select.

  In addition, the mobile communication terminal 200 notifies the communication server 100 of an ID list of a specific communication partner in advance, and when the battery runs out, the connection request of other transmission sources is limited. For this reason, by responding to a connection request having a low priority for the user, it is possible to prevent a situation in which communication is impossible due to battery exhaustion.

  Furthermore, the mobile communication terminal 200 can estimate the battery exhaustion time accurately by predicting the battery exhaustion time from the time-series battery remaining capacity profile. For this reason, the process in the communication server 100 becomes easy.

  Furthermore, the transmission interval of the remaining battery level information transmitted from the mobile communication terminal 200 is configured to depend on the measured remaining battery level. In this case, for example, when the estimated time of battery exhaustion approaches, the time of battery exhaustion can be estimated more finely by shortening the transmission interval. By setting a longer value, it is possible to suppress waste of electric power.

  While the present invention has been particularly shown and described with reference to exemplary embodiments, the invention is not limited to these embodiments and variations thereof. It will be apparent to those skilled in the art that various modifications can be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims.
