  Hereinafter, embodiments of a mobile radio terminal, a base station and a communication system according to the present invention will be described in detail with reference to the attached drawings. Note that the present invention is not limited by the following embodiments.

  FIG. 1 is a diagram showing an example of a schematic configuration of the communication system 1 of the present embodiment. As shown in FIG. 1, the communication system 1 includes a base station 10 and a plurality of mobile radio terminals 20. The base station 10 transmits later-described communication information including at least transmission information to a communication area (coverage of wireless communication) via the relay station 30. Thus, the mobile radio terminal 20 present in the communication area can receive the communication information from the base station 10, and the mobile radio terminal 20 present outside the communication area can not receive the communication information from the base station 10. . In the example of FIG. 1, the wireless communication between the base station 10 and each mobile wireless terminal 20 present in the communication range is half duplex wireless communication. Half-duplex wireless communication is a form of wireless communication in which only one of transmission and reception can be performed.

  FIG. 2 is a diagram showing an example of functions that each of the base station 10 and the mobile radio terminal 20 included in the communication system 1 of the present embodiment has. For convenience of explanation, although only one mobile radio terminal 20 is illustrated in the example of FIG. 2, the other mobile radio terminals 20 included in the communication system 1 also have the same function.

  As shown in FIG. 2, the base station 10 includes an accepting unit 11, a destination position information request unit 12, a destination position information acquisition unit 13, a designation unit 14, a generation unit 15, and a transmission unit 16. Have.

  The receiving unit 11 receives various inputs in response to an operation by an operator of the base station 10. For example, the receiving unit 11 specifies a destination and a group, and receives a transmission request for transmission information for the specified group (for convenience of description, referred to as “first transmission request”). Further, for example, the receiving unit 11 may also receive a transmission request for transmission information for a designated group (referred to as a “second transmission request” for convenience of explanation), in which only a group is designated without specifying a destination. it can. As an example, the transmission information of the present embodiment includes voice information corresponding to the content uttered while the operator presses the PTT (Push to Talk) switch, but the present invention is not limited to this.

  Hereinafter, the case where the reception unit 11 receives the first transmission request described above and the case where the reception unit 11 receives the second transmission request described above will be separately described. First, the case where the reception unit 11 receives the first transmission request described above will be described. The destination location information request unit 12 requests destination location information indicating the location of the destination specified in the first transmission request described above. In this example, the destination information request unit 12 requests destination position information from, for example, a map application that is an application for providing map information prepared in advance.

  The destination position information acquisition unit 13 acquires destination position information. In this example, the destination location information acquisition unit 13 acquires destination location information requested by the destination location information request unit 12 from a map application or the like. The destination location information can be represented, for example, by information indicating latitude and longitude.

  The designation unit 14 designates a range (area) within the communication range. For example, the designation unit 14 can designate one or more ranges according to the operation of the operator, or can designate one or more predetermined ranges.

  The generation unit 15 indicates, for each of the transmission information and one or more range information indicating the range of the communication area, a delay time information indicating a time to delay the start of notification of the transmission information and indicating a shorter value closer to the destination. And generating communication information including linked information. In this example, the communication information further includes a group ID identifying a group to be a group call, and destination specification call information indicating whether the call is for specifying a destination.

  Here, the association information in the present embodiment includes one or more range information corresponding to one or more ranges designated by the designation unit 14 and one or more range information corresponding to one to one (each one or more designated by the designation unit 14 Information linked with delay time information indicating the delay time with respect to the range so that the delay time becomes shorter as the range indicated by the range information is closer to the destination). is there. For example, based on the destination position information acquired by the destination information acquisition unit 13 and the one or more ranges designated by the designation unit 14, the generation unit 15 reduces the delay time as the range is closer to the destination. The delay time of each of the one or more ranges designated by the designation unit 14 is determined. Then, by associating delay time information indicating the determined delay time with each of the one or more ranges designated by the designation unit 14 and the one or more range information corresponding to one-to-one, the association information is generated. Can. For example, as shown in FIG. 3, it is assumed that three ranges (range A, range B, range C) are specified by the specification unit 14. FIG. 4 is a diagram showing an example of the association information in this case. In the example of FIG. 4, the delay time information linked to the range information indicating the range A closest to the destination indicates “0 seconds”. Further, the delay time information linked to the range information indicating the range B near the destination next to the range A indicates “n seconds (> 0)”. Further, the delay time information linked to the range information indicating the range C farthest from the destination indicates “2 n seconds”. The shape of each range is arbitrary, and may be, for example, a circle, a rectangle, or an ellipse.

  Returning to FIG. 2, the description of the generation unit 15 is continued. The generation unit 15 includes the association information generated as described above, transmission information corresponding to the above-mentioned first transmission request (transmission information to be the target of the above-mentioned first transmission request), and the above-mentioned first Communication information including a group ID identifying a group designated by the transmission request and destination designation calling information indicating that the call is for specifying a destination is generated. FIG. 5 is a diagram showing an example of communication information generated by the generation unit 15. As shown in FIG.

  The description of FIG. 2 is continued. The transmission unit 16 transmits the communication information generated by the generation unit 15.

  Next, the case where the receiving unit 11 receives the second transmission request described above will be described. When the receiving unit 11 receives the second transmission request described above, the transmitting unit 16 identifies the transmission information corresponding to the second transmission request described above and the group designated by the second transmission request described above. Communication information including a group ID and destination designation call information indicating that the call is not a call to designate a destination is transmitted.

  In the present embodiment, the base station 10 has a hardware configuration including a storage device such as a CPU, a ROM, a RAM, and the like, and the CPU executes the program stored in the storage device to obtain the above-described function (accepting unit 11 The destination position information request unit 12, the destination position information acquisition unit 13, the specification unit 14, the generation unit 15, and the transmission unit 16) are realized.

  The description of FIG. 2 is continued. As shown in FIG. 2, the mobile radio terminal 20 has a receiving unit 21, a storage unit 22, a position information management unit 23, a notification unit 24, a control unit 25, and a response unit 26. The receiving unit 21 receives communication information from the base station 10. The storage unit 22 stores the transmission information received by the receiving unit 21. In this example, the storage unit 22 stores voice information included in the transmission information received by the receiving unit 21.

  The position information management unit 23 manages position information indicating the position of the own station. In this example, the mobile radio terminal 20 is provided with a GPS device 40 that receives a signal from a communication satellite and detects its current position. The position information management unit 23 periodically acquires position information from the GPS device 40 and holds the acquired position information.

  The notification unit 24 notifies of transmission information. More specifically, under the control of the control unit 25, the notification unit 24 outputs a notification start sound and reproduces voice information stored in the storage unit 22.

  The control unit 25 is linked to the range information including the position of the own station when the position of the own station is included in the one or more pieces of range information included in the association information received by the receiving unit 21. Control is performed to delay the notification start time for starting the notification of the transmission information according to the delay time information. For example, it is assumed that the association information included in the communication information received by the receiving unit 21 is in the mode of FIG. 4. First, the control unit 25 includes three pieces of range information (in the example of FIG. 4, range information indicating the range A, range information indicating the range B, and range information indicating the range C) in the association information shown in FIG. It is assumed that the own station is determined to belong to the range A based on the location information of the own station. In the association information shown in FIG. 4, since the delay time information associated with the range information indicating the range A is “0 second”, the control unit 25 immediately starts the notification start time so as to start the notification of the transmission information. It can be calculated. In the following description, a value indicating the notification start time calculated in this case is referred to as a "predetermined value". For example, the notification start time may be a waiting time until the notification is started, and the predetermined value in this case is “0 seconds”. Further, it is assumed that the own station is determined to belong to the range B based on the three range information included in the association information shown in FIG. 4 and the position information of the own station. In the delay time designation information shown in FIG. 4, since the delay time information linked to the range information indicating the range B is “n seconds”, the control unit 25 reports a value obtained by adding n seconds to the above predetermined value. It can be calculated as the start time. Further, it is assumed that the own station is determined to belong to the range C based on the three range information included in the association information shown in FIG. 4 and the position information of the own station. In the delay time designation information shown in FIG. 4, since the delay time information linked to the range information for specifying the range C is “2 n seconds”, the control unit 25 adds 2 n seconds to the predetermined value. Can be calculated as the notification start time.

  Then, after the notification start time is calculated, the control unit 25 sets a timer for detecting that the notification start time has been reached. When the timer times out, the control unit 25 controls the notification unit 24 to notify the transmission information. If the notification start time is the above-described predetermined value, the control unit 25 may control the notification unit 24 to immediately notify transmission information without setting a timer. .

  In this example, the control unit 25 performs control to reproduce the audio information stored in the storage unit 22 after reaching the notification start time. More specifically, the control unit 25 controls the notification unit 24 to output a start sound of notification when the notification start time is reached, and then the notification unit 24 reproduces the audio information stored in the storage unit 22. Control the

  When the control unit 25 does not belong to any range (one or more ranges indicated by one or more range information included in the association information received by the receiving unit 21), the control unit 25 broadcasts the transmission information. It does not need to be performed, and it may delay and broadcast only arbitrary time rather than the time which the received maximum delay time information shows. It is sufficient if the mobile radio terminal 20 can set which one to use.

  The description of FIG. 2 is continued. The response unit 26 is substantially a transmission unit, and includes a microphone (not shown) for detecting the voice of the user of the mobile radio terminal 20 and a PTT switch for switching between transmission and reception. When the user of the mobile radio terminal 20 responds to the transmission information to the base station 10, the response unit 26 transmits response information indicating that the response has been completed. The response information is also transmitted to other mobile radio terminals 20 via the relay station 30. That is, when the own station responds to the transmission information, the response unit 26 transmits, to the other mobile radio terminal 20, response information indicating that the response has been completed. In the present embodiment, the control unit 25 receives the response information from the other mobile radio terminal 20, and when the own station is informing the transmission information, the notification unit 24 is configured to stop the notification of the transmission information. Control. Further, the control unit 25 controls the notification unit 24 so as not to broadcast the transmission information before receiving the response information from the other mobile radio terminal 20 and before starting to broadcast the transmission information. Also, the notification unit 24 may be controlled to notify that the response has been made.

  In the present embodiment, the mobile radio terminal 20 has a hardware configuration including a storage device such as a CPU, a ROM, a RAM, and the like, and the CPU executes the program stored in the storage device to execute the above-described function (receiving unit 21 realizes the position information management unit 23, the notification unit 24, the control unit 25, and the response unit 26). The storage unit 22 described above is realized by a storage device such as a ROM or a RAM.

  FIG. 6 is a flowchart showing an operation example of the mobile radio terminal 20 of the present embodiment when communication information is received from the base station 10. As shown in FIG. 6, the control unit 25 determines whether or not the group identified by the group ID included in the communication information received by the receiving unit 21 matches the group to which the own station belongs (step S1). When the result of step S1 is negative (step S1: No), the process ends, and when the result of step S1 is positive (step S1: Yes), the control unit 25 calls the destination designation included in the communication information. It is checked whether the information indicates that the call is for specifying a destination (step S2).

  If the result of step S2 is affirmative (step S2: Yes), the control unit 25 determines that the own station is either based on the one or more range information included in the association information of the communication information and the current position of the own station. It is checked whether or not it belongs to the range (one of one or more ranges indicated by one or more range information included in the association information) (step S3).

  When the result of step S3 is affirmative (step S3: Yes), the control unit 25 calculates the notification start time (step S4). As described above, the control unit 25 calculates, as the notification start time, a value obtained by adding the time indicated by the delay time information linked to the range to which the own station belongs to the predetermined value (step S4), and sets the timer. On the other hand, when the result of step S3 is negative (step S3: No), the control unit 25 confirms whether or not setting for performing notification processing is made (step S5). When the result of step S5 is negative (step S5: No), the process ends as it is (the notification of the transmission information is not performed). If the result of step S5 is affirmative (step S5: Yes), the control unit 25 further delays the time indicated by the maximum delay time information among the delay time information included in the received association information, and sets the delay time information. The notification start time is calculated according to the determined delay time (step S6). For example, the control unit 25 can also calculate, as the notification start time, a value obtained by adding the delay time set as described above to the above-described predetermined value.

  After the above-mentioned step S4 or the above-mentioned step S6, the control unit 25 checks whether the notification start time has been reached (step S7). In this example, whether or not the notification start time has been reached can be confirmed by confirming whether or not the timer has timed out. When the result of step S7 is affirmative (step S7: Yes), the control unit 25 controls the notification unit 24 to perform notification of the transmission information. That is, notification processing of transmission information is performed (step S8). The specific content is as described above.

  In addition, when the result of the above-mentioned step S2 is a negate (step S2: No), a process transfers to step S8 directly.

  As described above, the base station 10 according to the present embodiment indicates, for each of the transmission information and one or more range information indicating the range of the communication area, a time for delaying the start of transmission information transmission, and the destination The communication information including the association information in which the delay time information indicating a shorter value is associated with the closer to the transmission information is transmitted to the mobile radio terminal 20. When the mobile radio terminal 20 having received this communication information includes the position of its own station in one or more of the range information included in the association information of the communication information, the range information including the position of its own station is included in the mobile radio terminal 20. Control is performed to delay the notification start time for starting notification of transmission information according to the linked delay time information. In this way, it is possible to realize a mechanism that makes it possible to preferentially respond to mobile stations close to the destination.
