Description

  The present invention relates to an emergency call system, a private branch exchange, and a mobile terminal. For example, an emergency call ("110", "118", "119", etc.) from a mobile terminal accommodated in a private branch exchange (hereinafter abbreviated as PBX). Is also trying to respond.

Conventionally, the station side of a public network such as a carrier has information on the location (for example, xx prefecture xx city xx town xx chome xx number xx number, etc.) where telephones of general subscribers are accommodated. If there is an emergency call from a general subscriber, the station will obtain the nearest emergency call destination (for example, a police station or a fire department) from the subscriber's location information and report to that emergency call destination. (See Patent Document 1).
JP 11-252261 A

  Since the telephone number of a general subscriber has a one-to-one relationship with the address of the general subscriber, a public network station such as a carrier must obtain the position information of the general subscriber based on the telephone number. Can do.

  However, the extension terminal accommodated in the PBX does not have a telephone number in the public network, and when the extension terminal makes an emergency call, the position is specified by the telephone number of the PBX. When the extension terminal is connected to the PBX by wire, the distance between the PBX and the extension terminal is short, and even if the position is specified by the telephone number of the PBX, there is little problem.

  However, in a network configuration in which a PBX accommodates a mobile terminal (portable wireless telephone, PHS, etc.) via an access point device and is connected to a public IP telephone network, the position of the PBX and the position of the mobile terminal If the location of the emergency call source is specified by the PBX phone number and connected to the emergency call destination (for example, a police station or fire station), the remote police station or fire station cannot respond to the emergency call quickly. It may lead to.

  For example, when access point devices in a corporate network are installed in Tokyo and Osaka, and both access point devices are connected to a PBX installed in Tokyo, a person in Osaka can use a mobile terminal (extension terminal). 110 ”report will lead to the police station in Tokyo.

  Therefore, even in the case of an emergency call from a mobile terminal under a private branch exchange, an emergency call system, a private branch exchange, and a mobile terminal that enable the public network side to more accurately grasp the position of the mobile terminal that is the cause of the emergency call. It is desired.

In the emergency call system having a private branch exchange that sends an emergency call to the emergency exchange, the mobile terminal has location information adding means for adding the location information of the mobile terminal to the emergency call on the emergency call route of the private branch exchange from the mobile terminal. It is characterized by.

  A second aspect of the present invention is a mobile terminal accommodated in a private branch exchange via an access point device having jurisdiction, wherein the private branch exchange is connected to an external network that can be connected to an emergency call destination command board. A mobile terminal connected to an extension network including the mobile terminal and a GPS position information adding unit that adds position information of the GPS receiver to an emergency call. Features.

  Further, the third aspect of the present invention is connected to an extension network including a mobile terminal and an access point device having jurisdiction over the mobile terminal, and sends an emergency call to an external network connectable to an emergency call destination command board. In the private branch exchange, the access point location storage unit storing the location information of all the access point devices accommodated therein, and the location information of the access point device that relayed the emergency report when the emergency report was received And an access point position adding unit for adding to an emergency call as position information of the mobile terminal in a pseudo manner.

  Furthermore, the fourth aspect of the present invention is connected to an extension network including a mobile terminal and an access point device having jurisdiction over the mobile terminal, and sends an emergency call to an external network connectable to an emergency call destination command board. In the emergency call system having a private branch exchange, the private branch exchange stores the mobile terminal location storage unit that stores the location information of the mobile terminal that is the emergency call source, and the location information request from the command stand side, And a location information notifying unit that returns location information of the mobile terminal that is an emergency call source stored in the mobile terminal location saving unit.

  According to the present invention, even in the case of an emergency call from a mobile terminal subordinate to a private branch exchange, the public network side can more accurately grasp the position of the mobile terminal that is the cause of the emergency call.

  The emergency call destination data 22a is provided in a database device common to a plurality of IP telephone switching devices 2 outside the IP telephone switching device 2, and the IP telephone switching device 2 refers to this database when necessary. May be.

  Since the internal structure of the command board 7 is irrelevant to the present invention, the description thereof is omitted (the same applies to the embodiments described later).

(A-2) Operation of the First Embodiment The emergency call system of the first embodiment registers and holds the location information of the access point device 4 in advance by a maintenance person or the like in the PBX 3, and from the mobile terminal 5 The location information of the access point device 4 is added to the sent emergency call notification, and the emergency call is sent to the IP telephone network 1. The IP telephone exchange device 2 in the IP telephone network 1 determines a command board 7 for notifying an emergency call based on the position information of the access point device 4 in the emergency call.

  The PBX 3 holds information at the time of emergency call (mobile terminal extension number, access point device 4 at the time of outgoing call) so that it can be investigated later. In addition, information of the access point device 4 where the mobile terminal is perched is always held so that it can be investigated.

  FIG. 4 is a sequence diagram illustrating a schematic process of an emergency call from the mobile terminal 5 in the emergency call system according to the first embodiment.

  The transmission of an emergency call (here, “110”) from the mobile terminal 5 is supplemented by the access point device 4-1 having the mobile terminal 5 in the management area at that time (S 001), and the access point device 4-1. Converts the emergency call from wireless to wired and transmits it to the PBX 3 (S002).

  When the PBX 3 receives the emergency call transmission from the mobile terminal 5, the PBX 3 extracts the position information about the access point device 4-1 from the access point position data 13a, adds the position information to the emergency call, and the IP telephone network 1 An emergency call is sent to (S003). Note that SIP is generally used as a protocol between the PBX 3 and the IP telephone network 1, but in the case of SIP, for example, new information can be added to INVITE for transmission.

  In addition, when the emergency call transmission from the mobile terminal 5 is received, the PBX 3 writes the extension number of the emergency caller (mobile terminal 5) as the emergency call journal data 13b and stops at the time of the call. The location information of the access point device intervening in the notification is written as the location information of the access point device 4-1 and the access point device currently set as a perch (S004).

  The IP telephone exchange device 2 in the IP telephone network 1 that has received the emergency call from the PBX 3 notifies the emergency call based on the emergency call special number and the location information of the access point device 4-1 in the emergency call. The police station command board 7 is determined and an emergency call is transmitted to the command board 7 (S005). It is preferable that the location information of the access point device 4-1 is continuously added to the emergency call at this time.

  The emergency call with the mobile terminal 5 and the police station command board 7 can be established by the flow of the emergency call as described above.

  Even if the IP telephone exchange device 2 is a conventional device that simply determines the command board 6 based on the emergency call special number and the telephone number of the PBX 3, an emergency in which the location information of the access point device 4-1 is added. Since the notification reaches the command table 6, the display function enables the operator to switch to the command table 6 at an appropriate position.

  When the mobile terminal 5 moves and the other access point device 4-2 is a perch (S006) and the location registration is notified to the PBX 3 (S007), the PBX 3 stores the mobile terminal in the emergency call journal data 13b. The location information of the access point device that is currently the perch is updated to the information of the destination access point device 4-2 (S008).

  By storing the emergency call journal data 13b as described above, the emergency call journal data 13b can be used to investigate the emergency call later.

(A-3) Effect of the First Embodiment According to the first embodiment, the access point device when the mobile terminal makes an emergency call to the emergency call sent from the mobile terminal to the IP telephone network via the PBX Position information is added, so even if the position of the PBX and the access point device are significantly different, the position information of the mobile terminal is more accurate (for example, the xx building xx floor) on the IP telephone network side. Can be notified.

  In addition, information on the access point device of the perch has been saved as emergency call journal data, so if you investigate later, you can easily know who made the emergency call from where and where the mobile terminal is now. Can do.

  Furthermore, by using the emergency call journal data, PBX can easily cope with the reverse communication (call back) from the command board in the line hold state, and the emergency call between the mobile terminal and the command board can be easily repeated. Can be established.

(B) 2nd Embodiment Next, 2nd Embodiment of the emergency call system by this invention and a mobile terminal is described, referring drawings.

(B-2) Configuration of Second Embodiment The emergency call system of the second embodiment can also be represented by the network configuration shown in FIG. 2 according to the first embodiment. However, in the case of the second embodiment, the mobile terminal 5 has a GPS function.

  FIG. 5 is a block diagram illustrating an internal configuration of the mobile terminal 5 according to the second embodiment. The mobile terminal 5 according to the second embodiment includes a communication unit 30 including an antenna, a communication interface, and a modem, an audio processing unit 31 including a microphone, a speaker, an audio codec, a digital / analog mutual converter, a liquid crystal display, and a numeric keypad. In addition to the same configuration as the conventional one, such as an operation panel unit 32 composed of an LED and a panel interface, a control unit 33 composed of a CPU, and a storage unit 34, a GPS receiving unit 35 is provided. The GPS receiving unit 35 outputs position information using, for example, latitude, longitude, and altitude.

  When the emergency call special number is dialed to the operation panel unit 32, the control unit 33 takes position information from the GPS receiving unit 35, adds the position information to the emergency call, and wirelessly transmits it from the communication unit 30. It is.

  In the case of the second embodiment, the storage unit 13 of the PBX 3 does not store the access point position data 13a unlike the first embodiment. Unlike the first embodiment, the emergency call journal data 13b also includes the extension number of the emergency caller (mobile terminal 5) and the location information of the mobile terminal at the time of the emergency call.

  In the case of the second embodiment, the emergency call destination data 22a stored in the storage unit 22 of the IP telephone exchange device 2 is also for each type of emergency call (emergency call special numbers “110”, “118”, “119”). However, each type 22a1 to 22a3 of the emergency call destination data 22a is a combination range of latitude and longitude, and specific information on the specific command board 6 that becomes a report destination in the case of the range (for example, telephone) It consists of a set of number and IP address).

(B-2) Operation of the Second Embodiment The emergency call system of the second embodiment makes an emergency call including the GPS position information obtained by the GPS receiver 35 when the mobile terminal 5 makes an emergency call. The position 5 can be specified on the IP telephone network 1 or the command board 6 side. Further, in the PBX 3, when an emergency call is made, a journal is stored so that it can be used for later analysis.

  FIG. 6 is a sequence diagram illustrating an outline process of an emergency call from the mobile terminal 5 in the emergency call system of the first embodiment.

  When the emergency call special number (here, “110”) is dialed, the mobile terminal 5 takes in the GPS position information from the built-in GPS receiving unit 35, adds the GPS position information to the emergency call, and transmits it ( S010). The transmission of the emergency call is supplemented by the access point device 4-1 having the mobile terminal 5 in the management area at that time (S011), and the access point device 4-1 converts the emergency call from wireless to wired. It transmits to PBX3 (S012).

  When receiving the emergency call transmission from the mobile terminal 5, the PBX 3 performs a conversion process to the IP telephone network 1, but transmits the received emergency call to the IP telephone network 1 as it is (S013). Note that SIP is generally used as a protocol between the PBX 3 and the IP telephone network 1. For example, in the case of SIP, since new information can be added to INVITE, an emergency call including GPS location information can be transmitted. It can be carried out.

  The PBX 3 does not transmit the received GPS position information as it is and makes an emergency call to the IP telephone network 1, but the PBX 3 has a GPS position information-address information conversion table and converts the GPS information into address information. The IP telephone network 1 can be notified of address information.

  In addition, when receiving an emergency call transmission from the mobile terminal 5, the PBX 3 writes the field of the emergency call journal data 13b and the extension number of the emergency caller (mobile terminal 5) and is included in the emergency call. GPS information is written as position information at the time of reporting (S014).

  The IP telephone switching device 2 in the IP telephone network 1 that has received the emergency call from the PBX 3 notifies the emergency call based on the emergency call special number and the GPS position information in the emergency call. And an emergency call is transmitted to the command board 7 (S015). It is preferable that the GPS position information is continuously added to the emergency call at this time.

  The emergency call with the mobile terminal 5 and the police station command board 7 can be established by the flow of the emergency call as described above.

  Even if the IP telephone exchange device 2 is a conventional device that simply determines the command board 6 based on the emergency call special number and the telephone number of the PBX 3, the emergency call with GPS position information added to the command board 6. Therefore, the display function enables the operator to switch to the command stand 6 at an appropriate position.

  In the above, the case where the mobile terminal 5 includes the GPS position information only in the emergency call is shown, but the GPS position information is also included in the negotiation in the position registration process (including the handheld process) performed when the mobile terminal 5 moves. If it is passed, the latest location information of the mobile terminal 5 can be included in the emergency call journal data 13b in substantially the same manner as in the first embodiment.

  For example, GPS location information is also notified to the PBX 3 by the location registration process that is performed when the mobile terminal 5 makes another access point device 4-2 a perch. At this time, the PBX 3 is the latest in the emergency call journal data 13b. Is set to the received GPS position information.

  By storing the emergency call journal data 13b as described above, the emergency call journal data 13b can be used to investigate the emergency call later.

(B-3) Effects of the Second Embodiment According to the second embodiment, GPS location information obtained by the built-in GPS receiver is added to an emergency call sent from the mobile terminal to the IP telephone network via the PBX. Therefore, even if the positions of the PBX and the access point device are significantly different, more accurate position information can be notified to the IP telephone network as the position information of the mobile terminal.

  In addition, since the GPS position information is stored as emergency call journal data, it is possible to easily know who made the emergency call from where it is investigated later.

  Furthermore, by using the emergency call journal data, PBX can easily cope with the reverse communication (call back) from the command board in the line hold state, and the emergency call between the mobile terminal and the command board can be easily repeated. Can be established.

(C) Other Embodiments In the description of each of the above-described embodiments, various modified embodiments have been referred to. However, modified embodiments as exemplified below can be given.

  In each of the above embodiments, the emergency call including the position information is given to the command board 6. However, the PBX 3 provides the position information (access point device address, GPS position information) related to the emergency call source mobile terminal. The command board 6 may store the information on the PBX 3, request the position information from the PBX 3 based on the PBX information (such as a telephone number), and collect the position information from the PBX 3 via the IP telephone network 1. The position information stored in the PBX 3 is acquired as in the first embodiment or the second embodiment.

  Here, the path for collecting the location information of the mobile terminal may be acquired via a network different from the IP telephone network used for the call.

  At this time, the IP telephone exchange device 2 may determine the command board 6 as the notification destination based on the representative telephone number of the PBX 3, and based on the location information included in the emergency call, The command board 6 may be determined as a notification destination, and in any case, an emergency call that does not include position information is sent to the command board 6.

  Further, in the first embodiment, the information on the installation position of the access point device 4 is set as pseudo position information of the mobile terminal, but more detailed information may be added or changed. For example, the access point device 4 calculates the distance between the mobile terminal 5 and the access point device 4 from the received intensity when the access point device 4 receives an emergency call from the mobile terminal 5, and the access point device 4 It may be added to the position information. Further, for example, after the PBS 3 obtains distances for a plurality of access point devices in the vicinity of the access point device related to the emergency call based on the received electrolysis strength from the mobile terminal 5 that is the call source, the hyperbolic method for these distances is used. You may make it acquire position information and include the position information in an emergency call.

  Further, in the second embodiment, the mobile terminal is provided with a GPS receiver, and GPS location information is obtained and included in the emergency call. However, the method by which the mobile terminal obtains location information is limited to this. is not.

  The public network to which the PBX 3 is connected is not limited to the IP telephone network as in the above embodiments, and the present invention can be applied to an existing telephone network. Also, the extension network may be any network that conforms to the IP protocol and does not follow it.

  In the first embodiment, the PBX adds the location information of the access point device to the emergency call. In the second embodiment, the mobile terminal includes the location information in the emergency call. The access point device having jurisdiction over the mobile terminal that is the source of the emergency call may add its own location information to the emergency call.
