JP 2014-060659 A

The terminal station operates on the basis of various programs, definition files such as configuration files, telephone book data, etc. When these setting files related to the operation of the terminal station are changed, the changed setting files are It is necessary to update work to be read and applied to the terminal station.
In the conventional disaster prevention radio system, the control station cannot update the setting file of the terminal station via the radio line. Therefore, when a change occurs in the terminal station setting file, maintenance personnel go to the location where the individual terminal station is located, connect the maintenance terminal that stores the changed setting file to the terminal station, and perform maintenance. The setting file for the terminal station was updated by operating the terminal.

  However, since it is necessary to update the setting file for each terminal station, when there are a large number (for example, several hundreds) of terminal stations, it takes an enormous amount of time to complete the update work for all the terminal stations. It was. Further, since the terminal station that is being updated is in the maintenance mode, the terminal station cannot be operated during that time.

  The present invention has been made in view of the above-described conventional circumstances, and provides a wireless communication system capable of efficiently performing an update operation for reading and applying a changed setting file to a terminal station. The purpose is that.

In the present invention, in order to achieve the above object, the wireless communication system is configured as follows.
That is, in a wireless communication system including a control station, a base station connected to the control station, and a terminal station that performs wireless communication with the base station, the control station issues an instruction to transmit a setting file related to the operation of the terminal station. When the base station receives the setting file transmission instruction and the transmission method designation, the base file transmits the configuration file to the terminal station according to the designated transmission method. To do.

  With such a configuration, the operation of transmitting the changed setting file and reading it to the terminal station can be carried out without the maintenance staff visiting the installation location of the terminal station. In addition, the setting file can be transmitted by either the low-speed transmission method or the high-speed transmission method. For example, in the case of a low-speed transmission method, it is not necessary to shift the terminal station to the maintenance mode when transmitting the setting file by storing the setting file in the PCH of the control channel and transmitting the setting file. No need to stop. Further, for example, in the case of a high-speed transmission method, the setting file can be transmitted at a higher speed than when PCH is used by storing and transmitting the setting file in the FACCH of the communication channel.

Here, as one configuration example, the control station holds position information indicating which of the plurality of base stations is under the terminal station, and the base station that has the terminal station under the position information based on the position information. The setting file may be transmitted from the station.
As a result, it is possible to transmit the configuration file using only the base station that has the target terminal station under control, and it is possible to effectively use a small amount of radio resources and to limit the influence on the operation. .

Further, in the above configuration example, the location information is updated according to the movement of the terminal station, and the control station updates the location information after the update when the location information is updated during transmission of the setting file. Based on this, the base station used for transmission of the configuration file may be changed and the subsequent transmission may be continued.
Accordingly, even when the terminal station moves between base stations during transmission of the configuration file, the transmission of the configuration file can be continued, and the configuration file can be transmitted without affecting the operation.

As one configuration example, the control station may repeatedly transmit a setting file transmission instruction to the base station until a predetermined time or number of times is reached.
As a result, the configuration file can be transmitted to the terminal station more reliably while the base station and the terminal station are in the wireless section.

Further, as one configuration example, the control station transmits a setting file application instruction from the base station to the terminal station after transmitting the setting file, and the terminal station receives the setting file application instruction in response to receiving the setting file application instruction. You may make it apply the already applied configuration file.
As a result, the work of applying the changed setting file transmitted to the terminal station can be performed without the maintenance personnel having to go to the installation location of the terminal station. Note that the configuration file update instruction may be issued immediately after the configuration file is transmitted, or after a certain time after the configuration file is transmitted (for example, in anticipation of the time when the terminal station is assumed not to be operated). Also good.

Also, as one configuration example, the control station transmits a setting file version information request instruction from the base station to the terminal station, and the terminal station currently receives the setting file version information request instruction, The version information of the setting file being applied may be transmitted to the control station through the base station, and the control station may display the version information received from the terminal station.
Thereby, the operator of the control station can confirm the version of the setting file applied to the terminal station, and can grasp whether the setting file has been updated normally.

  According to the wireless communication system of the present invention, it is possible to efficiently perform an update operation for reading and applying a changed setting file to a terminal station.

A radio communication system according to the present invention will be described with reference to the drawings.
FIG. 1 shows a system configuration example of a disaster prevention radio system which is an example of a radio communication system. FIG. 2 shows a configuration example of the control station facility in the disaster prevention radio system.
The disaster prevention radio system of this example is generally configured by control station equipment having a control station 101 and a base station 102 and terminal station equipment having terminal stations such as a mobile station 103 and a fixed terminal station 104. In this example, two each of the base station 102, the mobile station 103, and the fixed terminal station 104 are provided, but the number of these is arbitrary.

The control station 101 is a station installed in an organization of a prefecture or a municipality, and performs connection control between a ground line such as a control table 203 for performing communication control and a mobile radio line.
The base station 102 is connected to the control station control apparatus 201 using a wired line, is installed at a plurality of bases such as a station other than the control station 101, and is a terminal existing in a zone (wireless communication area) of the own station Wireless communication with a station (mobile station 103 or fixed terminal station 104) or wireless relay between a terminal station and a terminal station is performed.

The mobile station 103 is mainly used by moving on land, and performs wireless communication with the base station 102 and other terminal stations. The mobile station 103 is mounted on a moving body such as a vehicle and moves, or is carried by a person.
The fixed station terminal 104 is fixedly installed at a branch office or disaster prevention related organization in a prefecture or municipality, and performs wireless communication with the base station 102 or other terminal stations, like the mobile station 103.
Each terminal station can also communicate with the control station 101 via the base station 102.

The control station control device 201 performs control such as call management and communication control between a terminal station and a ground line such as a control table 203 and a PBX (private branch exchange).
The operation management device 202 performs system information defining the operation of the disaster prevention radio system, management of communication information of the terminal station, and maintenance control of the disaster prevention radio system.
The control table 203 instructs the terminal station for communication control and the like.

Hereinafter, the operation of the terminal station will be described by taking the mobile station 103 as an example, but it goes without saying that the same applies to the fixed station terminal 104.
FIG. 7 shows an example of a frame configuration used for communication between the base station 102 and the mobile station 103. (A) is an example of a frame configuration of a control channel used for connection control of a wireless line, and (b) is an example of a frame configuration of a communication channel for a call.

The control channel frame consists of 6-bit R (burst transient response guard time), 2-bit P (preamble), 112-bit CAC / E (control signal / collision control bit), and 20-bit SW (synchronization word) 2 bits CI (carrier information), 6 bits CC (color code (interference countermeasure code)), 168 bits CAC / E (control signal / collision control bit), 4 bits I (idle bits) total 320 It consists of bits.
Here, the CAC (control signal) includes PCH (simultaneous call channel), BCCH (broadcast channel), and SCCH (dedicated zone signaling channel).

  The communication channel frame consists of 6 bits R (burst transient response guard time), 2 bits P (preamble), 112 bits TCH (traffic channel) or FACCH (high speed associated control channel), 20 bits SW (synchronization) Word), 2-bit CI (carrier information), 6-bit CC (color code (interference countermeasure code)), 20-bit slow associated control channel (SACCH) or RCH (housekeeping channel), 144-bit TCH (traffic) Channel) or FACCH (high-speed associated control channel), and 8-bit B / I (busy / idle bit), a total of 320 bits.

  In the disaster prevention radio system of this example, when a change occurs in various setting files related to the operation of the mobile station 103 (for example, definition files such as programs, configuration files, telephone book data, etc.), the control station 101 Remote download is performed to transmit the setting file to each mobile station 103 via 102.

In this example, the operation management apparatus 202 can select low-speed remote download that transmits a configuration file using the PCH of the control channel or high-speed remote download that transmits the configuration file using the FACCH of the communication channel. It is like that.
Whether the low-speed remote download or the high-speed remote download is performed may be selected by the operator of the operation management apparatus 202, or various factors such as the type of the setting file, the importance of the change contents, and the urgency level. May be automatically selected by the operation management apparatus 202 in light of a predetermined standard.

FIG. 3 shows an example of a low-speed remote download sequence using PCH.
The first mobile station 103 existing in the zone of the first base station 102 transmits a location registration request addressed to the control station controller 201 to the first base station 102 (step 301). Further, the second mobile station 103 existing in the zone of the second base station 102 transmits a location registration request addressed to the control station control device 201 to the second base station 102 (step 303).
The first and second base stations 102 transfer the received location registration request to the control station controller 201 (steps 302 and 304).

  Based on the location registration request received via the first or second base station 102, the control station control device 201 detects the location information of the first and second mobile stations 103 (association between the mobile station and the base station). ) Is registered (step 305). That is, the first mobile station 103 is registered under the first base station 102, and the second mobile station 103 is registered under the second base station 102. Further, the control station control device 201 updates the target base station information (step 306). In this example, both the first and second mobile stations 103 are registered in the group 00, and the target base station information of the group 00 is the first and second base stations 102.

  The operation management apparatus 202 selects PCH as the download type, selects group 00 as the download target (step 307), and divides the setting file as download data into N (N is an integer of 2 or more) (step 308). . Thereafter, the operation management apparatus 202 transmits a remote maintenance request in which file download information including download data (1 / N) is set to the control station control apparatus 201 (step 309). Here, the download data (n / N) means the nth data among the N divided download data.

The control station control apparatus 201 transfers the file download information to the first and second base stations 102 that are target base stations of the group 00 (step 310). The file download information is transferred using the licensee specific information defined in ARIB STD-T79.
When receiving the licensee specific information from the control station control apparatus 201 (step 311), the first base station 102 stores the licenser specific information in the PCH of the control channel and transfers it to the first mobile station 103 (step 311). 312). Further, when the second base station 103 receives the licenser specific information from the control station control apparatus 201 (step 314), the second base station 103 stores the licenser specific information in the PCH of the control channel and transfers it to the second mobile station 103. (Step 315).

The first and second mobile stations 103 obtain the download data (1 / N) from the received licensee specific information and store it in the memory (steps 313 and 316). In addition, since the group number is set in the licenser specific information and the group number is registered in the mobile station 103 in advance, the first and second mobile stations 103 that have received the licenser specific information are assigned to themselves. Download data is saved only from the licensee specific information that matches the registered group number (group 00 in this example).
After transmitting the file download information, the control station control device 201 transmits a remote maintenance response (normal response) to the operation management device 202 (step 317).

The same download process as in steps 309 to 317 is performed in the same manner for the remaining download data divided into N (steps 318 to 326).
After transmitting all the N-divided download data, the operation management apparatus 202 repeats the series of download data processing in steps 309 to 326 until the designated number of times or designated time specified in advance (step 327). The section between the first and second base stations 102 and the first and second mobile stations 103 is a wireless section, and the licenser specific information stored in the control channel PCH is always the first and second mobile stations. Since it does not reach the station 103, repeated transmission ensures that the N-divided download data reaches the first and second mobile stations 103 more reliably.

Thereafter, the operation management apparatus 202 transmits a remote maintenance request in which update instruction information for the group 00 is set to the control station control apparatus 201 (step 328).
The control station control apparatus 201 transfers the update instruction information to the first and second base stations 102 that are the targets of the group 00 set in the update instruction information (step 329). The transfer of the update instruction information is performed using licensee specific information defined in ARIB STD-T79.

When receiving the licensee specific information from the control station control apparatus 201 (step 330), the first base station 102 stores the licenser specific information in the PCH of the control channel and transfers it to the first mobile station 103 (step). 331). Further, when the second base station 103 receives the licenser specific information from the control station control apparatus 201 (step 333), the second base station 103 stores the licenser specific information in the PCH of the control channel and transfers it to the second mobile station 103. (Step 334).
When the first and second mobile stations 103 have acquired update instruction information from the received licensee-specific information, if all of the N-divided download data has been received, the original download data obtained by combining them In order to apply (setting file), the file is updated (steps 332 and 335).

After transmitting the update instruction information, the control station control apparatus 201 transmits a remote maintenance response (normal response) to the operation management apparatus 202 (step 336).
The operation management apparatus 202 repeats the transmission of the update instruction information until the designated number of times or the designated time specified in advance (step 337). By repeating the transmission of the update instruction information in this way, the update instruction information reaches the first and second mobile stations 103 more reliably.

Thereafter, the operation management apparatus 202 transmits a remote maintenance request in which version confirmation information for the group 00 is set to the control station control apparatus 201 (step 338).
The control station control apparatus 201 transfers the version confirmation information to the first and second base stations 102 that are the targets of the group 00 set in the version confirmation information (step 339). The transfer of the version confirmation information is performed using licensee specific information defined in ARIB STD-T79.

When receiving the licenser specific information from the control station control apparatus 201 (step 340), the first base station 102 stores the licenser specific information in the PCH of the control channel and transfers it to the first mobile station 103 (step 340). 341). When the second base station 103 receives the licenser specific information from the control station control apparatus 201 (step 342), the second base station 103 stores the licenser specific information in the PCH of the control channel and transfers it to the second mobile station 103. (Step 343).
After transmitting the version confirmation information, the control station control apparatus 201 transmits a remote maintenance response (normal response) to the operation management apparatus 202 (step 344).

When the first and second mobile stations 103 acquire the version confirmation information from the received licensee-specific information, the license information indicates the version information (version information of the setting file after updating the file based on the download data) being applied to itself. The unique information is set and transmitted to the control station control apparatus 201 using the control channel PCH (steps 345 and 348).
The first and second base stations 102 transfer the received licensee specific information to the control station controller 201 (steps 346 and 349).

The control station control apparatus 201 acquires version information from the licensee specific information, sets it as a remote maintenance notification, and transmits it to the operation management apparatus 202 (steps 347 and 350).
The operation management apparatus 202 displays the received version information on the screen for each individual number of the first and second mobile stations 103 (step 351). Note that the operation management apparatus 202 does not repeatedly transmit a remote maintenance request in which version confirmation information is set. By repeatedly transmitting, the first and second mobile stations 103 transmit the same version information to the first and second base stations 102 many times, and the traffic in the radio section may increase. Because there is. When the operation management apparatus 202 cannot acquire version information, the process related to the acquisition of version information (steps 338 to 351) is performed in response to a user instruction.

  Here, the operation management apparatus 202 can designate not the group designation (group 00 in this example) but the individual number of the mobile station 103 as the download target. The procedure is similar. For example, when only the individual number of the first mobile station 103 is designated, in steps 310, 319, 329, and 339, the first registration with the first mobile station 103 is set in the location registration information. Only the base station 102 is the transmission target.

FIG. 4 shows an example of a sequence in the case where a handoff occurs during low-speed remote download using PCH.
Here, it is assumed that the second mobile station 103 has moved from the zone of the second base station 102 to the zone of the first base station 101 after the download process of download data (1 / N). Note that the sequence of steps 401 to 417 until the download process of the download data (1 / N) is completed is the same as the sequence of steps 301 to 317 in FIG.

When the second mobile station 103 moves from the zone of the second base station 102 to the zone of the first base station 101 during execution of the download sequence, the second mobile station 103 sends a location registration request addressed to the control station controller 201 to the first base station. Transmit to the station 102 (step 418).
The first base station 102 transfers the received location registration request to the control station controller 201 (step 419).

  Based on the location registration request received via the first base station 102, the control station control device 201 updates the location information (linkage between the mobile station and the base station) of the second mobile station 103 (step) 420). That is, the second mobile station 103 is added under the control of the first base station 102, and the second mobile station 103 is deleted from the control of the second base station 102. As a result, the first and second base stations 103 belonging to the group 00 are both under the control of the first base station 102, and the target base station information of the group 00 is only the first base station 102.

  Thereafter, the control station control apparatus 201 receives the remote maintenance request in which the file download information including the download data (2 / N) is set from the operation management apparatus 202 (step 421), and the target base station of the group 00 The file download information is transferred to the first base station 102 using the licensee specific information (step 422).

When receiving the licenser-specific information from the control station controller 201 (step 423), the first base station 102 stores the licenser-specific information in the PCH of the control channel and transfers it to the first and second mobile stations 103. (Step 424).
The first and second mobile stations 103 obtain the download data (2 / N) from the received licensee specific information and store it in the memory (steps 425 and 426).
After transmitting the file download information, the control station control apparatus 201 transmits a remote maintenance response (normal response) to the operation management apparatus 202 (step 427).
Since the subsequent processing is the same as the sequence after step 318 in FIG. 3 except that the target base station of group 00 is only the first base station 102, description thereof will be omitted.

FIG. 5 shows an example of a high-speed remote download sequence using FACCH.
The sequence of steps 501 to 506 until the target base station information of group 00 is updated is the same as the sequence of steps 301 to 306 in FIG.

  The operation management apparatus 202 selects FACCH as the download type, selects group 00 as the download target (step 507), and divides the setting file as download data into N (N is an integer of 2 or more) (step 508). . Thereafter, the operation management apparatus 202 transmits a remote maintenance request in which file download information including download data (1 / N) is set to the control station control apparatus 201 (step 509). Here, the download data (n / N) means the nth data among the N divided download data.

Next, the control station control apparatus 201 determines whether or not the group 00 is in a call connection state (a state in which a call can be made and a call can be made) (step 510). The call connection state can be determined from the presence or absence of call information. When call information is present, the call connection state is established. When call information is absent, the call connection state is not established.
When the group 00 is not in the call connection state (step 501; N), the control station control apparatus 201 transmits a remote maintenance response (abnormal response) to the operation management apparatus 202 (step 511), and the target base station of the group 00 The call setup is transmitted to the first and second base stations 102 (step 512).

  When receiving the call setting from the control station control apparatus 201 (step 513), the first base station 102 transfers the call setting to the first mobile station 103 (step 514) and sends a call setting response to the control station control apparatus 201. (Step 515). When the second base station 102 receives the call setting from the control station control apparatus 201 (step 516), the second base station 102 transfers the call setting to the second mobile station 103 (step 517) and controls the call setting response to the control station control. The data is transmitted to the device 201 (step 518). As a result, the group 00 is brought into a call connection state.

  When receiving the remote maintenance response (abnormal response) from the control station control apparatus 201, the operation management apparatus 202 retransmits the remote maintenance request having the same content to the control station control apparatus 201 (step 519). As a result of the retransmission, if the group 00 is in call connection (during processing in steps 512 to 518), the control station control device 201 transmits a remote maintenance response (abnormal response) to the operation management device 202 (step 511).

  When the group 00 is in a call connection state (step 501; Y), the control station control apparatus 201 transfers file download information to the first and second base stations 102 that are target base stations of the group 00 (step 520). ). The file download information is transferred using the licensee specific information defined in ARIB STD-T79.

The subsequent sequence after step 521 is basically the same as the sequence after step 311 in FIG. 3 (remote download using PCH).
However, transmission of licensee specific information from the first and second base stations 102 to the first and second mobile stations 103 is performed using the FACCH of the communication channel.
Further, every time the control station control apparatus 201 receives a remote maintenance request from the operation management apparatus 202, it is confirmed whether the group 00 is in the call connection state (step 529), and if it is not in the call connection state, the processing of steps 511 to 519 is performed. To call connection state.
Even if the group 00 is released due to a failure of the control station control device 201 or the operation management device 202 during the execution of the download sequence, the download sequence is automatically executed by executing the processing of steps 510 to 519. To resume.

FIG. 6 shows an example of a sequence when handoff occurs during high-speed remote download using FACCH.
Here, it is assumed that the second mobile station 103 has moved from the zone of the second base station 102 to the zone of the first base station 101 after the download process of download data (1 / N). Note that the sequence of steps 601 to 627 until the download process of download data (1 / N) is completed is the same as the sequence of steps 501 to 527 in FIG.

When the second mobile station 103 moves from the zone of the second base station 102 to the zone of the first base station 101 during execution of the download sequence, the second mobile station 103 sends a recall setting request addressed to the control station controller 201 to the first base station 101. Transmit to the base station 102 (step 628).
The first base station 102 transfers the received recall setting request to the control station controller 201 (step 629).
Based on the received recall setting request, the control station control apparatus 201 transmits a recall setting response addressed to the second mobile station 103 to the first base station 102 (step 630).
The first base station 102 transfers the received recall setting response to the second mobile station 103 (step 631).

When the handoff sequence (steps 628 to 631) is successful, the control station control apparatus 201 updates the position information (linkage between the mobile station and the base station) of the second mobile station 103 (step 632). That is, the second mobile station 103 is added under the control of the first base station 102, and the second mobile station 103 is deleted from the control of the second base station 102. As a result, the first and second base stations 103 belonging to the group 00 are both under the control of the first base station 102, and the target base station information of the group 00 is only the first base station 102.
The control station control apparatus 201 releases the call information of the second base station 103 because there are no mobile stations in group 00 in the second base station 103 (steps 633 and 634).

  Thereafter, the control station control apparatus 201 receives the remote maintenance request in which the file download information including the download data (2 / N) is set from the operation management apparatus 202 (step 635), and the group 00 is in the call connection state. If the group 00 is in the call connection state, the file download information is transferred to the first base station 102, which is the target base station of the group 00, using the licensee specific information. (Step 637).

When receiving the licensee specific information from the control station control apparatus 201 (step 638), the first base station 102 stores the licensee specific information in the FACCH of the communication channel and transfers it to the first and second mobile stations 103. (Step 639).
The first and second mobile stations 103 obtain the download data (2 / N) from the received licensee specific information and store it in the memory (steps 640 and 641).
After transmitting the file download information, the control station control apparatus 201 transmits a remote maintenance response (normal response) to the operation management apparatus 202 (step 642).
Since the subsequent processing is the same as the sequence after step 518 in FIG. 5 except that the target base station of group 00 is only the first base station 102, description thereof will be omitted.

As described above, the disaster prevention wireless system of this example performs wireless communication with the control station 101 including the control station control apparatus 201 and the operation management apparatus 202, the base station 102 connected to the control station 101, and the base station 102. Terminal station 103.
Then, the control station 101 transmits a setting file transmission instruction related to the operation of the terminal station 103 to the base station 102 together with designation of a low-speed transmission method or a high-speed transmission method, and the base station 102 transmits a setting file transmission instruction. When the transmission method designation is received, the configuration file is transmitted to the terminal station 103 in accordance with the designated transmission method.

  Therefore, according to the disaster prevention radio system of the present example, the operation of causing the terminal station 103 to read the changed setting file can be performed without going to the place where the terminal station 103 is installed. In addition, the setting file can be transmitted by either the low-speed transmission method or the high-speed transmission method. Further, in the case of a low-speed transmission method (using the control channel PCH), it is not necessary to shift the terminal station to the maintenance mode when transmitting the setting file, and it is not necessary to stop the operation of the terminal station. In the case of a high-speed transmission method (using the communication channel FACCH), the setting file can be transmitted at a higher speed.

  In the disaster prevention radio system of this example, a plurality of terminal stations 103 are grouped in advance, and the control station 101 designates transmission of setting files to the plurality of terminal stations 103 and subsequent instructions in units of groups. It is configured to do so. For this reason, it is possible to efficiently update the setting file for a plurality of terminal stations 103.

  Further, in the disaster prevention radio system of this example, the control station 101 is also configured to be able to specify the terminal stations 103 individually for transmission of setting files to the plurality of terminal stations 103 and subsequent instructions. For this reason, it is possible to cope with a setting file update operation for only a specific terminal station 103 without waste.

  Further, in the disaster prevention wireless system of this example, the control station 101 holds position information indicating which of the plurality of base stations 102 the terminal station 103 exists, and based on the position information, the terminal station 103 The configuration file is configured to be transmitted from the base station 102 having the terminal 103 under control. For this reason, it becomes possible to transmit the configuration file using only the base station 102 under the control of the target terminal station 103, and it is possible to effectively use a small amount of radio resources and to limit the influence on the operation. Can do.

  In the disaster prevention radio system of this example, the location information is updated according to the movement (handoff) of the terminal station 103, and the control station 101 updates the location information when the location information is updated during transmission of the setting file. On the basis of the position information, the base station 102 used for transmission of the setting file is changed and the subsequent transmission processing is continued. For this reason, even if the terminal station 103 moves between the base stations 102 during transmission of the configuration file, the transmission of the configuration file can be continued, and the configuration file can be transmitted without affecting the operation. .

  Moreover, in the disaster prevention radio system of this example, when the control station 101 designates FACCH and transmits the setting file of the terminal station 103, the target terminal station 103 (the terminal corresponding to the designated group number or individual number) When the station 103) is in a call connection state (a state in which a call is already connected and can talk), a setting file is transmitted from the base station 102 that has made a call connection with the terminal station 103, whereas the station 103 is not in a call connection state Is configured to perform call connection from the base station 102 under the control of the terminal station 103 to the terminal station 103, and to transmit the configuration file after the terminal station 103 is changed to the call connection state. Yes. For this reason, even if the target terminal station 103 is not in the call connection state, there is no problem in transmission of the setting file.

  Further, in the disaster prevention radio system of this example, when the control station 101 transmits the setting file of the terminal station 103 by designating FACCH, if the target terminal station 103 is in the process of call connection, the setting file The terminal station 103 is configured to transmit the setting file after transitioning to the call connection state. For this reason, even if the target terminal station 103 is in the process of call connection, there is no problem in transmission of the setting file.

  In the disaster prevention radio system of this example, the control station 101 specifies the FACCH and transmits the setting file of the terminal station 103. When the call connection with the target terminal station 103 is released, the control station 101 The base station 102 under the control of the station 103 performs call connection to the terminal station 103, and after the terminal station 103 is changed to the call connection state, transmission of the configuration file is resumed. For this reason, even if the call connection is released due to equipment failure or the like during the transmission of the setting file, the call connection can be automatically restarted after the failure is recovered and the transmission of the setting file can be resumed.

  In the disaster prevention radio system of this example, the control station 101 is configured to repeatedly transmit a setting file transmission instruction to the base station 102 until a predetermined time or number of times is reached. For this reason, the configuration file can be transmitted to the terminal station more reliably while the base station 102 and the terminal station 103 are in the wireless section.

  In the disaster prevention radio system of this example, the control station 101 transmits a setting file update instruction from the base station 102 to the terminal station 103 after transmitting the setting file, and the terminal station 103 receives the setting file update instruction. In response to this, the received configuration file is configured to be applied. For this reason, the work of applying the changed setting file transmitted to the terminal station 103 can be carried out without going to the place where the terminal station 103 is installed.

  In the disaster prevention radio system of this example, the control station 101 transmits a request instruction for setting file version information from the base station 102 to the terminal station 103, and the terminal station 103 receives a request instruction for setting file version information. In response to this, the version information of the applied setting file is transmitted to the control station 101 through the base station 102, and the control station 101 is configured to display the version information received from the terminal station 103. Therefore, the operator of the control station 101 can confirm the version of the setting file applied to the terminal station 103, and can grasp whether the setting file has been updated normally.
