Description

  The present invention relates to an emergency call location information transfer system for transferring location information indicating the location of a caller who made an emergency call, and in particular, from a primary reception stand that received an emergency call first, a secondary reception with different jurisdiction. The present invention relates to a transfer system for transferring position information to a table.

  In recent emergency call systems such as the 110th and 119th calls, the communication environment has been improved with the spread of mobile phones and IP phones, and the location is automatically determined without having to ask the reporter verbally. Information can be acquired.

  Normally, emergency calls are received at the emergency call reception desk (hereinafter referred to as “reception desk”) of the police or fire department, but in the case of an emergency call from a mobile phone, the communications business The position information indicating the position of the wireless base station or the like that receives the radio waves of the calling telephone is transmitted from the carrier DB server owned by the person to the reception stand, and thus the transmission position can be specified on the reception stand side. It is possible. In recent years, mobile phones with a GPS function have become widespread, and in the case of notifications from such phones, it is also possible to directly specify the location of the mobile phone instead of the location of the radio base station. Yes.

  In addition, a report may be made with non notification setting, and in that case, the location information is not automatically transmitted from the carrier DB server, but if the reception table requests the carrier DB server to transmit the location information, It is possible to acquire position information. The location information request to the carrier DB server can be made any number of times as long as the call is not disconnected, although there is a restriction that the emergency call is being connected and is permitted only from the reception desk that has accepted the call. . For this reason, it is possible to obtain the latest information every time a request for location information is made, and this is particularly effective for a report where the reporter is likely to move, such as a report from a mobile phone. is there.

  However, in the emergency call system, the position information is transmitted only to the reception desk that accepts the emergency call, regardless of whether the position information is automatically transmitted or the position information is transmitted upon request. Is done. For this reason, even if the location of the whistleblower is located or the accident site is outside the jurisdiction area of the reception desk that received the emergency call, even if the call is forwarded to another reception desk, the location information will be accepted first. There is a problem in that the location information cannot be acquired by the transfer destination reception desk.

  As a solution to the above problem, the carrier DB server uses a caller information transmission system (for example, see Patent Document 1) that converts position information into a PB signal (push button signal) and transmits it together with a voice signal. It is conceivable to acquire position information. If the location information is acquired using the above transmission system, the location information is transferred along with the audio signal even if the emergency call is transferred to another reception desk. Is possible.

JP 2003-32366 A

  However, when an emergency call is transferred using the above transmission system, the location information is transferred in the state of a PB signal, so that the PB signal sound (push sound) is superimposed on the call voice and hinders the call. In some cases, there was a risk of hindering information gathering from the whistleblower. In addition, in the transfer method using the transmission system described above, for an emergency call with non notification setting, if the location information is not acquired at the reception desk that first received the report, the voice signal is transmitted even if the report is transferred. Therefore, there is also a problem that the reception desk at the transfer destination cannot acquire the position information.

  Therefore, the present invention has been made in view of the problems in the conventional technology described above, and can transfer position information without affecting the audio signal when transferring an emergency call to another reception desk. To provide a location information transfer system at the time of an emergency call that realizes that the destination reception desk can acquire location information even if the location information is not acquired at the reception desk that first received the report And

  In order to achieve the above object, the present invention provides a positional information transfer system at the time of an emergency call that transfers position information indicating the position of an emergency caller from a primary reception desk that first received the emergency call to a secondary reception desk. A transfer trunk in which the first exchange accommodating the primary reception stand has a first transfer line for transferring a voice signal at the time of an emergency call and a second transfer line for transferring the position information. The voice signal and the position information are transferred through different lines when an emergency call is transferred to the second exchange accommodating the secondary reception stand.

  According to the present invention, when transferring an emergency call from the primary reception desk to the secondary reception desk, since the voice signal and the position information are transferred through different lines, the transfer of the position information affects the transfer of the voice signal. It is possible to avoid giving the position information, and it becomes possible to transfer the position information while maintaining the voice quality.

  In the location information transfer system at the time of an emergency call, the transfer trunk can be configured to transfer the location information by using the UUI function of the ISDN line. Transfer processing can be performed.

  In the location information transfer system at the time of an emergency call, the first exchange includes request signal transmission means for transmitting a request signal for requesting transmission of the location information to a DB server holding the location information. When the secondary reception base issues a request signal for requesting transmission of position information, the transmission means receives the request signal issued by the secondary reception base and relays the received request signal to the DB It can be configured to send to a server. According to this configuration, since the first exchange relays the request signal for the location information issued by the secondary reception stand to the DB server, the location information can be requested from the secondary reception stand to the DB server. Even if the position information is not acquired by the primary reception stand, the secondary reception stand can acquire the position information.

  In the location information transfer system at the time of an emergency call, the first exchange relays the request signal to the DB server when the request signal transmission means receives the request signal issued by the secondary reception stand. Can be provided with a selection means for selecting whether to permit or not, and according to this, it is possible to prevent the relay of the request signal in a situation that the person in charge of the primary reception stand cannot recognize it can.

  In the location information transfer system at the time of emergency call, the first exchange returns the location information from the DB server in response to the number of transmissions of the request signal by the request signal transmission means and the transmission of the request signal. It is possible to provide history management means for counting at least one of the number of replies and recording the counted number. According to this configuration, statistics regarding acquisition of position information according to a request signal can be obtained for each reception stand, and can be used for management of communication costs, investigation of a report status, and the like.

  In the location information transfer system at the time of the emergency call, when the first exchange is a report with the non-notification setting, the carrier exchange contains the communication terminal that has issued the emergency call. Facility information requesting means for requesting facility information of a communication terminal and facility information transmitting means for transmitting facility information returned from the carrier exchange to the DB server can be provided. According to this configuration, the telephone number information of the reporter can be provided to the DB server, and the location information from the DB server even when the location information is not automatically transmitted from the DB server as in the case of an emergency call with non notification setting. It becomes possible to get.

  In the location information transfer system at the time of emergency call, the location information is information indicating the location of the mobile communication terminal that issued the emergency call, or information indicating the location of the radio base station that receives the radio wave emitted by the mobile communication terminal. It can be.

  As described above, according to the present invention, in the location information transfer system at the time of emergency call, when transferring the emergency call to another reception stand, the location information can be transferred without affecting the audio signal, Even when the location information is not acquired at the reception desk that has received the report first, it is possible to realize that the reception desk at the transfer destination can acquire the location information.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an overall configuration diagram showing an embodiment of a position information transfer system at the time of emergency notification according to the present invention. In the following description, an example will be described in which an emergency call from the mobile phone 1 is received by the primary reception stand 11 and transferred to the secondary reception stand 20 having different jurisdiction from the primary reception stand 11.

  The carrier switch 2 is a switch that accommodates a radio base station (not shown) that receives a radio wave transmitted from the mobile phone 1, and the carrier DB server 3 includes the telephone number information of a contractor who subscribes to a communication carrier, This is a server for storing location information (latitude, longitude) of the radio base station. When the mobile phone 1 has a GPS function, the GPS position information is also stored in the carrier DB server 3.

  The exchange 4 is an exchange that connects the carrier exchange 2 and the primary reception board 11, and performs an emergency line trunk 5 that connects an emergency call from the mobile phone 1 to an emergency call line, and a transmission signal multiplexing and separation process. The time-sharing control device 6 for performing, the reception desk trunk 7 for connecting the emergency call transmitted through the emergency call line to the primary reception board 11, the position information control section 8 for requesting the position information, etc., and the entire exchange 4 And a transfer trunk 21 that is connected to the transfer ISDN line 13 and transfers an emergency call received by the primary reception board 11 to the secondary reception board 20.

  Further, the exchange 4 receives the position information transmitted from the carrier DB server 3 and requests the position information receiving apparatus 10 to transmit to the primary reception stand 11 and the carrier DB server 3 to transmit the position information. Is connected to the forced acquisition history management control unit 12 that manages the history when the message is acquired. In the following, in order to distinguish between the case where the position information is automatically transmitted from the carrier DB server 3 and the case where the position information is acquired by requesting the carrier DB server 3 to transmit the position information, the latter is referred to as “forced”. Sometimes called “acquisition”.

  The exchange 14 is an exchange that connects the exchange 4 and the secondary reception stand 20, and includes a transfer acceptance trunk 15 that connects an emergency call transferred from the primary reception stand 11 to an emergency call line, a time division control device 16, and the like. The trunk 17 for the reception stand for connecting the emergency call connected to the emergency call line to the secondary reception stand 20, the position information control unit 18 for requesting the position information, etc., and the central controller for controlling the entire exchange 14 19.

  Next, the operation of the positional information transfer system having the above configuration will be described with reference to FIGS. Here, prior to the emergency call transfer process, first, a procedure for acquiring position information when an emergency call is received will be described with reference to FIG.

  When an emergency call is made, first, an audio signal is transferred to the carrier exchange 2 and connected to the exchange 4 from the carrier exchange 2. The exchange 4 is connected to the emergency call line via the emergency reception trunk 5, and is connected to the emergency call line and the reception stand trunk 7 via the time division control device 6, and the voice is sent to the primary reception stand 11. Transmit the signal. Thereafter, the person in charge of the primary reception stand 11 performs a reception operation, thereby establishing a call with the reporter.

  In parallel with this, the location information acquisition process is executed. This process is performed when the caller makes an emergency call in the notification setting and in the non-notification setting as shown in FIG. The procedure differs depending on the case.

  When the emergency call is a notification setting (step S1: No), at the time when the caller makes a call, the carrier switch 2 sends the call information indicating that an emergency call has been made to the carrier DB server 3. In addition to the notification, the caller ID information of the mobile phone 1 used at that time is notified. Next, the carrier DB server 3 uses the notified caller number information to identify the radio base station that receives the radio wave of the mobile phone 1 and extracts the location information of the identified radio base station. If the mobile phone 1 has a GPS function, the GPS location information of the mobile phone 1 can be taken out instead of the location information of the radio base station.

  Next, the extracted position information is transmitted to the position information receiving apparatus 10 (step S2), and then the position information receiving apparatus 10 develops the received position information on the primary reception stand 11 (step S3). The primary reception board 11 automatically analyzes and searches the map and address from the received position information, and displays them on a monitor device (not shown) (step S4). Thereby, the location of the reporter can be specified simultaneously with the voice call, and accident information and the like can be heard from the reporter while utilizing the location information.

  On the other hand, when the emergency call is set to non notification (step S1: Yes), the location information is not automatically transmitted from the carrier DB server 3 to the location information receiving apparatus 10, and therefore the primary reception stand 11 is set to voice. Although the call is established, the position of the reporter cannot be specified.

  In this case, the person in charge of the primary reception stand 11 performs a position information request (forced acquisition) operation, requests facility information from the carrier switch 2 via the emergency line trunk 5, and acquires facility information (step). S5). The acquisition of the facility information is a function that is effective only for an emergency call, and the facility information includes telephone number information, a control code, and the like of the mobile phone 1 that has made the emergency call.

  When the facility information is received from the carrier switch 2, the position information control unit 8 of the switch 4 transmits the facility information (caller number information) to the carrier DB server 3 via the position information receiving device 10, and transmits the position information. A request signal for requesting is transmitted (step S6).

  Receiving the position information request, the carrier DB server 3 extracts the position information based on the transmitted facility information, and transmits the position information to the position information receiving apparatus 10 on the condition that the notification is connected (step S7). ). In this case, if the notification has already been disconnected, a rejection response is transmitted to notify that the position information cannot be transmitted (step S8).

  Thereafter, as in the case where the emergency call is a notification setting, the primary reception board 11 automatically analyzes and searches the map and address based on the received position information and displays the map and address on the monitor device or the like (step S9). , S10). However, when the position information is acquired by requesting the position information (forced acquisition), after the position information is acquired, the fact that the force is acquired from the primary reception stand 11 to the central control device 9 of the exchange 4 is transmitted to the central control device. 9 requests the forced acquisition history management control unit 12 to count up the number of forced acquisitions, and leaves a history of the location information request (number of records and date / time) (step S11).

  Next, the procedure of the transfer process for transferring the emergency call received at the primary reception stand 11 to the secondary reception stand 20 will be described with reference to FIG.

  As shown in FIG. 3, when the emergency call is transferred, first, the person in charge of the primary reception desk 11 performs a transfer operation to connect to the ISDN line 13 for transfer via the transfer trunk 21 of the exchange 4. Then, the voice signal is transferred to the exchange 14 of the secondary reception stand 20 (step S21). Next, the exchange 14 receives the transferred voice signal once by the transfer acceptance trunk 15 and transmits the received voice signal to the secondary reception stage 20 via the time division control device 16 and the reception desk trunk 17. To do. Thereafter, the secondary reception desk 20 receives the transmitted voice signal, thereby establishing a voice call between the person in charge of the secondary reception desk 20 and the reporter.

  In parallel with this, a position information transfer process is performed. The position information transfer process differs depending on whether or not the primary reception board 11 has acquired the position information when an emergency call is received.

  When the location information is acquired at the primary reception stand 11 at the time of receiving an emergency call (step S22: Yes), the central controller 9 of the exchange 4 uses the location information acquired at the time of receiving the emergency call as a transfer trunk 21. And transmits the position information to the exchange 14 using the UUI (User User Information) function of the D channel of the ISDN line 13 for transfer (a control line different from the line for transmitting the voice signal) (step S23). ). Here, the UUI is a packet service that can be freely used in text. By using this function, position information can be transferred without affecting the audio signal being transferred.

  Next, the position information control unit 18 of the exchange 14 analyzes the transferred position information and develops the position information on the secondary reception table 20 (step S24), whereby the position information is stored on the secondary reception table 20. Provided. After that, the secondary reception stand 20 automatically analyzes and searches the map and address from the received position information, and displays them on the monitor device or the like (step S25).

  On the other hand, when the location information is not acquired by the primary reception stand 11 at the time of receiving an emergency call (step S22: No), the primary reception stand 11 does not own the location information. The location information is not transferred spontaneously. For this reason, the person in charge of the secondary reception stand 20 performs a position information acquisition (forced acquisition) operation, and uses the UUI interface of the ISDN line 13 for transfer from the central controller 19 of the exchange 14 to request the position information. Is transmitted (step S26).

  The transmitted request information is received by the position information control unit 8 of the exchange 4 via the transfer trunk 21. The position information control unit 8 analyzes the received request information and receives the position information from the secondary reception stand 20. The position information request process indicating that there has been a request is transmitted to the central controller 9 (step S27). Next, the central control device 9 inquires of the primary reception stand 11 whether or not to permit the request from the secondary reception stand 20, and if the person in charge of the primary reception stand 11 permits the request, the emergency line trunk 5 The facility information is requested to the carrier exchange 2 and the facility information is acquired (steps S28 and S29).

  If the person in charge of the primary reception stand 11 does not permit the request, the central control unit 9 informs the secondary reception stand 20 through the UUI that the request for position information cannot be permitted. Is dismissed.

  When the facility information is received from the carrier exchange 2, the central controller 9 requests the forced acquisition history management control unit 12 to count up the number of forced acquisitions, and the forced acquisition operation of the location information is performed from the primary reception stand 11. A history of position information requests is left (step S30).

  Next, the location information control unit 8 of the exchange 4 transmits the caller ID information and a request signal for requesting transmission of the location information to the carrier DB server 3 (step S31). The transmitted position information request signal is transmitted to the carrier DB server 3. Thereafter, the carrier DB server 3 retrieves and returns the position information based on the caller ID information, and the position information receiving unit 10 of the exchange 4 receives the returned position information (step S32).

  Then, the position information receiving apparatus 10 returns the received position information to the central control apparatus 9, and transfers the position information to the exchange 14 via the D channel of the transfer ISDN line 13 (step S33). Next, the position information control unit 18 of the exchange 14 analyzes the position information and develops the position information on the secondary reception stand 20 (steps S34 and S35), whereby the position information is provided to the secondary reception stand 20. The After that, the secondary reception stand 20 automatically analyzes and searches the map and address from the received position information, and displays them on the monitor device or the like (step S36).

  In addition, even if the primary reception stand 11 has already acquired the position information, there is a case where it is desired to acquire the latest position information again on the secondary reception stand 20 side. New position information can be provided to the secondary reception stand 20 by following the same procedure as the processing of S26 to S36 (transfer processing when the primary reception stand 11 has not acquired the position information).

  As described above, according to the present embodiment, when an emergency call is transferred from the primary reception desk 11 to the secondary reception desk 20, the position information is transferred using a line different from the line that transmits the voice signal. Therefore, it is possible to avoid the transfer of the position information from affecting the transfer of the audio signal, and it is possible to transfer the position information while maintaining the sound quality. At this time, since the location information is transferred using the UUI function of the ISDN line, it is possible to perform transfer processing with excellent immediacy.

  Furthermore, according to the present embodiment, since the exchange 4 that accommodates the primary reception stand 11 relays the request signal for the position information issued by the secondary reception stand 20 and transmits it to the carrier DB server 3, The position information can be requested from the table 20 to the carrier DB server 3, and even when the position information is not acquired by the primary reception table 11, the secondary reception table 20 can acquire the position information.

  Further, according to the present embodiment, when relaying the position information request signal issued by the secondary reception stand 20, the person in charge of the primary reception stand 11 is inquired whether or not to permit the relay. Since it is configured, it is possible to prevent the relay of the request signal in a situation where the person in charge of the primary reception stand 11 cannot recognize.

  Furthermore, according to the present embodiment, since the forced acquisition history management control unit 12 that manages the forced acquisition history of position information is provided, statistics regarding the forced acquisition of position information can be obtained for each reception desk, and the communication cost can be reduced. It can be used for management and investigation of reporting status.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above-described configuration, and various modifications can be made within the scope of the invention described in the claims.

  For example, in the above embodiment, the location information is transferred from the primary reception board 11 to the secondary reception board 20 using the UUI function of the ISDN line and the D channel of the same line, or the secondary reception board 20 If the line for transmitting the information is a line different from the line for transferring the audio signal, another transfer method is used to transmit the position information request signal to the primary reception board 11. Transfer or transmission of a request signal may be performed.
