Description

  The present invention relates to a position information acquisition control device, and in particular, when an emergency call from a mobile terminal is connected, the position of the person to be searched, that is, the position of the mobile terminal, is limited to a reception desk that is actually talking or has made a call. The present invention relates to a position information acquisition control device capable of acquiring information.

  In the field of emergency call, the caller of the mobile terminal recognizes only special numbers such as “110”, “118”, and “119”. For this reason, the caller of the mobile terminal dials the special number to make a voice call or a videophone call. However, in practice, an optimum reception desk is selected on the network side, and a connection destination of a call by voice telephone or video telephone is determined. In this case, the caller does not recognize which reception stand is making a call, and recognizes a collection of a plurality of reception stands only by a special number.

At this time, there is a possibility that acquisition of position information is requested from the reception board in connection with the emergency call. For example, Patent Document 1 describes a technique for detecting the location of a caller using an DGPS (Differential GPS) method when an emergency call is made. Patent Document 2 describes a technique for selecting a caller service area in an exchange and making a call to an emergency contact using the service area in emergency exchange. Furthermore, Patent Document 3 describes a technique for notifying location information of a portable terminal when an emergency call such as No. 110 is transmitted. In addition to these, in the prior art, there is provided a function of performing control after setting in advance whether the acquisition of position information is permitted or not permitted in units of reception desks.

FIG. 1 is a block diagram showing a configuration example of a position information acquisition system using a position information acquisition control device according to the present invention. In the figure, the position information acquisition system of this example includes a mobile terminal (Mobile Station: MS) 1 that moves together with a user who is a search target, and a base station (Base Transceiver Station: BTS) 2 that forms a wireless area 10. A radio network controller (Radio Network Controller: hereinafter referred to as RNC) 3 that controls the base station 2 and a mobile switching center (hereinafter referred to as MSC) that functions as a location information acquisition control device. 4, mobile communication gateway switching center (hereinafter referred to as GMSC) 5 for performing signal conversion processing between the mobile communication line network and the fixed telephone line network, and provision of position information about the mobile terminal 1 A subscriber information management device (Gateway Mobile Location Center: hereinafter referred to as GMLC) 6 having a function and a plurality of reception boards 7 functioning as communication terminals for the emergency contact 20 are configured. That.

  The MSC 4 has functions as shown in FIG. 2 by a hardware configuration as a well-known server device such as a CPU (Central Processing Unit), a memory, an input / output interface, a communication device, and a display device. That is, referring to the figure, the MSC 4 receives the call history storage function 40 for storing and holding the call information between the mobile terminal and the reception board, and accepts the call based on the call information stored and held by the call history storage function 40. The authentication function 41 for authenticating the machine, the conversion function 42 for converting the ID of the reception board into the special number transmitted by the mobile terminal 1 after the authentication by the authentication function 41, and the position using the special number after the conversion by the conversion function 42 After the information acquisition request is transmitted to the mobile terminal 1, the position information acquisition function 43 for acquiring the position information of the mobile terminal 1 is included, and the position information of the mobile terminal 1 acquired by the position information acquisition function 43 is notified to the reception stand 7 To do.

The authentication function 41 determines whether the call partner of the mobile terminal 1 and the reception stand 7 match when a call is currently being performed between the mobile terminal 1 and the reception stand 7. In addition, when the call between the mobile terminal 1 and the reception board 7 is finished, the authentication function 41 confirms that the mobile terminal 1 and the reception board 7 have made a call within a certain time.
The call information stored and held as call history by the call history storage function 40 in the MSC 4 is information including a call destination, a call end time, and the like. By referring to this call history, it is possible to authenticate the reception desk where the mobile terminal is currently talking or the reception desk where the mobile terminal has made a call in the past within a certain time.

  The MSC is provided for each radio area. When the mobile terminal 1 moves from the radio area 10 to another radio area, the MSC exists in the destination radio area from the MSC present in the source radio area. The call history is notified to the MSC. Therefore, the MSC 4 has a call history notification function 44 that notifies the call history to other MSCs. That is, the call history notification function 44 notifies the call information stored and held by the call history storage function 40 to a device corresponding to the change destination area when the area where the mobile terminal is located is changed. It is a function.

By the way, in the emergency contact 20, a plurality of reception stands 7 exist for one telephone number (for example, “110”) for load distribution. In this case, an appropriate aggregate of the reception stands 7 uses one searcher ID in common.
In such a configuration, in this system, when a position information acquisition request is received from the reception desk 7, the call history between the mobile terminal 1 of the search target person and the reception desk 7 is confirmed, Only when it is confirmed that a call has been made within a certain period of time, acquisition of position information is allowed. On the other hand, positioning of location information from a reception desk that is not actually making a call is not allowed on the network side. By controlling in this way, it is possible to acquire the position information while ensuring the searchee's privacy to the maximum when the position information acquisition request is transmitted to the searchee's mobile terminal 1. Become.

  In addition, when the position information acquisition request is received, the ID of the searcher, that is, the reception table 7 is notified. When this is notified to the mobile terminal 1 of the search target, the reception table dialed by the search target 7 is converted into a special number (for example, “110”), which is an aggregate of 7 and notified. By converting in this way, the search target person can recognize only the emergency call special number and transmit / receive position information.

Hereinafter, the location information acquisition process will be described separately when the mobile terminal is performing special number connection communication and when the mobile terminal is waiting.
(Location information acquisition processing during communication)
Processing for acquiring position information during special number connection communication between the mobile terminal and the reception board will be described with reference to FIG. This figure is a sequence diagram showing signals and the like transmitted and received at the mobile terminal 1, RNC 3, MSC 4, GMSC 5, GMLC 6, and reception board 7 of the search target person.

In the figure, the user of the mobile terminal 1 dials the emergency call special number ("110" in this example) to make a call (S101). Then, a call origination request is sent to the MSC 4 via the RNC 3 (S102). The MSC 4 expands the special number “110” to the back number (S103). For example, “110” is converted to “03-1111-1111”.
Further, this call request is sent to the reception board 7 via the GMSC 5 (S104, S105), and connection processing is performed (S106). After this connection process, the mobile terminal 1 and the reception board 7 are in a state of communicating by voice phone or video phone (S107).

  Thereafter, when a location information acquisition request linked to a call is activated from the reception desk 7 (S108), the reception desk 7 transmits a location information acquisition request to the MSC 4 (S109). This position information acquisition request includes the ID of the searcher, that is, the reception board 7 (77777777 in this example). This position information acquisition request is received by the MSC 4 via the GMLC 6 (S110). The MSC 4 that has received the position information acquisition request searches for the current call state of the search target person. In this example, since the call state is “busy”, it is determined whether or not the call destination (that is, the call partner of the mobile terminal) matches the position information acquisition request source (that is, the reception desk 7).

  In MSC4, the back-end number of the voice telephone or video-phone connection corresponding to the emergency call special number and the searcher ID of the connected reception desk are registered in advance. Do. For example, as shown in FIG. 4, the connection destination number “03-1111-1111” corresponding to the representative number “110”, the searcher ID “77777777”, and the connection number corresponding to the representative number “118” are connected. MSC4 stores a database of a connected back number “03-3333-3333” and a searcher ID “99999999” corresponding to the back number “03-2222-2222”, the searcher ID “88888888”, and the representative number “110”. This information is stored in advance in a memory, a hard disk, etc., and a determination is made with reference to this database.

Returning to FIG. 3, if the result of the determination is that they match, it is determined that the user's privacy is secured, the searcher ID is converted to a special number, and then a location information acquisition request is sent to the mobile terminal 1. Transmit (S111 → S112 → S113). That is, at this time, a special number dialed by the search target person is set as the searcher ID.
The mobile terminal 1 of the search target person who has received the position information acquisition request can recognize that the acquisition of the position information is requested from the reception desk of the call destination, and transmits a position information acquisition response to the MSC 4 (S114). It becomes possible to start position information positioning (S115). In this position information positioning process, a GPS (Global Positioning System) function built in the mobile terminal 1 is activated to measure the current latitude and longitude of the mobile terminal 1 itself, and the result is referred to as “position information”.

  The position information obtained by this position information positioning (S115) is transmitted from the MSC 4 to the reception board 7. In this case, after the searcher ID converted to the special number is converted into the original searcher ID (S116), the obtained position information is transmitted to the reception board as a position information acquisition response (S117, S118). With the above processing, a series of operations is completed.

(Location information acquisition processing during standby)
A process in the case where the position information is acquired after the call between the mobile terminal and the reception board is completed, that is, during standby will be described with reference to FIG. This figure is a sequence diagram showing signals and the like transmitted and received at the mobile terminal 1, RNC 3, MSC 4, GMSC 5, GMLC 6, and reception board 7 of the search target person.
In the figure, the user of the mobile terminal 1 dials the emergency call special number ("110" in this example) to make a call (S201), and then transmits a disconnection request (S202). The call has already ended. Assuming that. When the disconnection request is transmitted, the searcher ID of the call destination is stored and held in the MSC 4 (S203). Thereafter, the disconnection request is transmitted to the reception board 7 via the GMSC 5 (S204 → S205). Thereby, a cutting process is performed (S206).

  Thereafter, when a location information acquisition request linked with a call is activated from the reception desk 7 (S207), the reception desk 7 transmits a location information acquisition request to the MSC 4 (S208). This position information acquisition request includes the ID of the searcher, that is, the reception board 7 (77777777 in this example). This position information acquisition request is received by the MSC 4 via the GMLC 6 (S209). The MSC 4 that has received the position information acquisition request searches for the current call state of the search target person. In this example, since the call state is “waiting” after the call has already been disconnected, the history information is referred to. In this case, it is determined whether or not the location information acquisition request source ID, that is, the searcher ID exists in the history information of a call within a certain time (S210).

As a result of this determination, if the history of making a call within a certain period of time can be confirmed, it is determined that the user's privacy is secured, the searcher ID is converted to a special number, and then directed to the mobile terminal 1 The position information acquisition request is transmitted (S210 → S211 → S212). That is, at this time, a special number dialed by the search target person is set as the searcher ID.
The mobile terminal 1 of the search target person who has received the position information acquisition request can recognize that the acquisition of the position information is requested from the reception desk of the call destination, and transmits a position information acquisition response to the MSC 4 (S213). It becomes possible to start position information positioning (S214). In this position information positioning process, the GPS function built in the mobile terminal 1 is activated to measure the current latitude and longitude of the mobile terminal 1 itself, and the result is referred to as “position information”.

  The position information obtained by this position information positioning (S214) is transmitted from the MSC 4 to the reception board 7. In this case, after the searcher ID converted to the special number is converted into the original searcher ID (S215), the obtained position information is transmitted to the reception board as a position information acquisition response (S216, S217). With the above processing, a series of operations is completed.

(Modification)
In the above example, the location information of the mobile terminal 1 is acquired by the GPS function provided in the mobile terminal 1, but instead, the base station in the area where the mobile terminal 1 is located (that is, the visited base) The MSC 4 may acquire the position information based on information transmitted from the (station). That is, since each base station transmits its own ID, if the ID is confirmed in the MSC 4, the position of the base station can be grasped, and this may be used as position information. Also in this case, the ID of the reception stand on the search side is converted into a special number transmitted by the mobile terminal, and the location information is acquired after notifying the mobile terminal of the converted special number.

  In addition, if another apparatus in which the position information of the mobile terminal 1 is registered is provided in the present system, a result obtained from the apparatus may be “position information”. Further, this apparatus may be integrated with the MSC 4 and the location information of the mobile terminal 1 may be registered in the MSC 4. Also in these cases, the ID of the reception desk on the search side is converted into a special number transmitted by the mobile terminal, and the location information is acquired after notifying the mobile terminal of the converted special number.

(Summary)
As described above, in this system, the mobile communication subscriber switching center performs the location information acquisition permission control based on the call information between the reception desk that is the searcher and the searchee's mobile terminal, and the searchee's When the searcher ID is notified to the mobile terminal, the searcher ID is converted into a special number that is a collection of reception desks, so that the searchee recognizes only the special number of the emergency call while ensuring the privacy of the searchee. Position information can be sent and received.

  The present invention can be used when acquiring location information of a mobile terminal at the time of emergency call connection from the mobile terminal.
