Description

  The present invention provides an emergency call using information related to a caller such as location information of a caller when an emergency call is made from a portable terminal to an emergency call receiving agency such as a fire department or police via a mobile communication network. The present invention relates to an emergency call system that can be connected to a receiving organization by telephone.

When a telephone line is formed by an emergency call to a fire department (119), police (110), etc., the fixed telephone system and the emergency call reception center that is an emergency call connection are always in the same administrative district. It becomes. In other words, in the case of a landline telephone, the caller can always call directly to the appropriate emergency call reception center.
On the other hand, emergency calls from mobile terminals may not be received at the center of the administrative district (local government) where the accident occurred, since the emergency call reception center of the report destination is determined by the base station that received the radio waves of the mobile terminal, The operator at the emergency call reception center confirms the location of the accident (the municipality where the call originated), and in the case of an accident in a different administrative district, the operator who received the emergency call transfers to the emergency notification reception center in the responsible administrative district.

  Based on FIG. 9, the connection path so far when a report is made from the portable terminal 101 to the emergency call reception center such as the fire department or the police will be described. When an emergency call is received from the area of the base station A, the mobile terminal 101 is connected to the base station A 121, the mobile network switch, and the carrier network 102 of the fixed network switch. The carrier network 102 distributes the emergency call to the City A emergency call reception center 105, which is the same administrative district A as the base station A121, based on the information of the base station, and establishes a communication path between the mobile terminal 101 and the emergency call reception center 105. Form.

  However, as shown in FIG. 10, in the emergency call from the area 122a of the base station B122 in the administrative district A, since the radio wave reception is the base station B122, the carrier network 102 determines that it is an emergency report of the administrative district B. The emergency call is distributed to the B city emergency call reception center 103 to form a communication path.

  FIG. 11 shows the emergency call transfer procedure. The operator of the emergency call reception center has already found out that the call is received from the portable terminal 101 by the incoming call display of the reception device 151, and the operator's acceptance procedure is “report disaster content” (in the case of firefighting) First, “ka” first aid ”),“ name and phone number ”, and“ current location (disaster location) ”are confirmed. When the disaster occurrence location is outside the responsible administrative district, the forwarding operation is processed at the emergency call reception center in the administrative district. After the operator confirms the content of the report in this way, the operator will transfer it to the emergency call reception center in charge of the location of the accident, and it will take time from the start of the report to the operator's processing, and as a result to the department in charge. There is a problem that the communication of is delayed. In addition, during the transfer, the holding sound is basically not played and the sound is silent, so that the caller becomes anxious and sometimes disconnects the call, further exacerbating the delay in communication. Here, the confirmation of the telephone number is important information for connection from the emergency call reception center side because of the possibility of disconnection of the caller.

In addition, when there are many witnesses such as accidents and fires due to the positional relationship in FIG. 10, the emergency call reception center operator who is not in charge is busy with the transfer operation, and the emergency call from the original responsible administrative district In some cases, the response to the notification may be delayed. (If the call volume exceeds a certain level, the caller will hear a message and wait for a connection with the operator.)
Several technologies that may be able to cope with such a problem are disclosed as open gazettes, and will be described sequentially.

  First, an emergency information transmission method using a terminal of a mobile communication system disclosed in Japanese Patent Laid-Open No. 2002-92265 uses a mobile terminal provided with position information acquisition means for acquiring position information of the current position as the terminal. A method in which the position information acquisition means acquires position information of the current position of the mobile terminal a, the mobile terminal transmits position information to the server b, and the server transmits the position information transmitted in stage b. A step c for searching for an emergency contact address determined in advance, a step d in which the server translates information including the position information transmitted in step b into a language determined in accordance with the position information, and a server Includes step e of transmitting the information translated in step d to the emergency contact searched in step c. This method is particularly suitable for a mobile communication system that performs international roaming. Examples of emergency contacts here include police agencies, medical institutions, and financial institutions. An example of position information acquisition means is GPS (Global Positioning System).

According to this first disclosed technology, it is possible to reliably report to the police in an emergency even overseas, and banks other than those that have business relations or have a business alliance with that bank. Even if there is only a case, it is possible to carry out a procedure for remittance from his / her account to a financial institution close to the current position without bothering the relatives in his / her home country.
Second, the emergency support system disclosed in Japanese Patent Application Laid-Open No. 2002-269363 includes an insurance company server of an insurance company and a mobile terminal of a contractor who can communicate from abroad and contracts the insurance of the insurance company. The mobile terminal is provided with a guidance request means for requesting insurance company servers to provide insurance assistance for emergency situations such as accidents. The insurance company server includes the contents of the emergency situation and the mobile phone. Reception information for prompting notification of the current location information of the terminal is stored in association with the reception information transmitting means for transmitting to the mobile terminal and the coping destinations such as the hospital, police, and local office in association with the location and the map information of the location. A coping destination storage means, a coping destination searching means for searching for a coping destination corresponding to the contents of the emergency and the current location information of the mobile terminal, and a map of the coping destination of the searched coping destination. And addressed destination transmitting means for transmitting to the portable terminal is provided, the portable terminal has a structure in which the addressed destination display means for displaying the address destination and map information received on the screen is provided.

  According to the second disclosed technology, even if an emergency situation occurs in an insurance contractor, the mobile terminal is connected to the insurance company server via the network, and is input according to the reception information transmitted from the insurance company server. By simply sending a map of the handling destination, you can quickly go to the handling destination even when you are unfamiliar with the trip, especially overseas.

  Thirdly, an emergency call method disclosed in Japanese Patent Application Laid-Open No. 2000-165828 includes a mobile terminal that performs wireless communication, a base station that performs wireless communication with the mobile terminal, and a radio network controller connected to the base station. In the emergency call system of a mobile terminal equipped with an emergency call reception unit that copes with an emergency situation such as a fire or a failure, the mobile station's telephone number and the base station accommodating the base station that received the outgoing signal from the mobile terminal Receives communication from a plurality of radio channel control stations, and a radio channel control station provided with base station information adding means for adding location information and a radio channel control station code of a radio channel control station connected to the base station. Based on the mobile phone switching center that sends this to the relay switching center and the radio network controller code entered in the incoming signal transmitted from the mobile phone switching office, the most appropriate emergency communication for that radio network controller A relay switching center that distributes this incoming signal to the switching office for offices connected to the receiving section, and an emergency call receiving section that is most appropriate for the radio network controller of the radio network controller code based on the incoming call from the relay switching office A switching center for a station that reports an incoming signal, and when a radio network controller receives an emergency call transmitted from the mobile terminal via a base station, the telephone number of the mobile terminal and the base station The base station accommodation position information and the wireless channel control station code are added, and the relay switching center is connected to the optimal emergency call reception unit based on the wireless channel control station code. In this configuration, an emergency call from the mobile terminal is received by the emergency call reception unit that is optimal for a control station.

According to the third disclosed technique, the emergency call from the mobile terminal can be received directly to the optimum reception unit for the radio network controller that has received the report from the mobile terminal. For example, an appropriate response can be taken much earlier than when an emergency call is received at a central emergency center provided for each prefecture, and then routed to an optimal reception unit.

As described above, the first disclosed technique, the second disclosed technique, and the third disclosed technique have been explained, but even with these disclosed techniques, the speed of emergency notification cannot be sufficiently maintained.
Certainly, if the first disclosure technology and the second disclosure technology are applied, the reporter operates the mobile terminal to transmit the location information to the server, and obtains the emergency call reception center information corresponding to the location information. If you can, you can make a call directly to the emergency call reception center in charge of the place where the accident occurred, but before the caller who is likely to be upset by an emergency situation makes a call It is obvious that inquiring of the server for information on the emergency call reception center in charge of the location is not realistic, and the speed of emergency calls cannot be sufficiently secured. Conversely, there is a high possibility that the conventional method of transferring from the emergency call reception center that is not in charge of the accident location to the emergency call reception center is quick.

Next, if the third disclosed technique is applied, an appropriate emergency call reception center is determined based on the code of the radio network controller instead of the base station, so that it is approximately the same as the emergency call system of FIG. You can make a call directly to the emergency call reception center in charge. Here, “substantially the same” means that the emergency call system in FIG. 1 determines an appropriate emergency call reception center based on the base station, whereas the third disclosed technique controls the base station. This is because an appropriate emergency call reception center is determined based on the radio network control station to be used. In any case, as shown in the emergency call system of FIG. 2, when the emergency call reception center is determined based on the radio network controller and base station for the critical part of the area in charge of the emergency call reception center, There is a case where there is no emergency call reception center and a call is forced to be transferred.
In addition, the number of emergency calls from mobile devices has been increasing year by year, and the rate of notifications exceeds 50%, so it is important to speed up emergency calls as much as possible to shorten the time until arrival at the site. The solution of is demanded.

  The present invention provides an emergency call system capable of making a call with an appropriate emergency call reception center without burdening the operation of the user and without passing through the operation of the operator at the emergency call reception center as much as possible. For the purpose.

  (1) In the emergency call method according to the present invention, the private branch exchange of the emergency call reception center forms a call path between the mobile terminal and the call device of the emergency call reception center via the carrier network for the emergency call sent from the mobile terminal. A method for making an emergency call, in which a mobile terminal transmits an emergency call, and a mobile terminal having a function for acquiring latitude / longitude transmission position information acquires a transmission position of latitude / longitude at the time of transmission A process of transmitting the transmission location to the private branch exchange of the emergency call reception center of the emergency call destination determined by the route determination of the communication facility of the carrier network, and the emergency call reception center determined by the route determination An emergency call reception center that identifies the emergency call reception center that has jurisdiction over the location indicated by the call origination location based on the call location received by the private branch exchange If the process and the emergency call reception center specified in the emergency call reception center identification process are the same as the emergency call reception center determined by route determination, call with the private branch exchange in the emergency call reception center determined by route determination An emergency determined by route determination when the emergency call reception center specified in the route determination and the emergency call reception center specified in the emergency call reception center identification step are not the same as the emergency call reception center determined by the route determination. A private branch exchange in the report reception center transfers to the private branch exchange in the emergency call reception center specified in the emergency call reception center identification process, and a private branch exchange in the emergency call reception center transferred in the transfer process. , A transfer-with-communication path forming process for forming a communication path with the communication device of the emergency call reception center. Is included.

This includes a manual transfer rule formation step of associating the base station identification information of a certain base station with the sector for the base station where the mobile terminal was located when the emergency call was issued, and recording it in the storage means.

  As described above, in the present invention, the emergency call reception center transferred in the above process and the identification information of the base station that has received the radio wave from the mobile terminal when the emergency call is transmitted and the mobile terminal when the emergency call is transmitted in the base station. Is recorded in the storage means in association with the sector where the location is located, so that the emergency call reception center in charge can be obtained using the identification information of the base station and the sector as a key, and not only the identification information of the base station but also the sector is used. Therefore, even if an emergency call is made from a caller located in an overlapping area between base stations, the emergency call reception center is specified based on a smaller sector than the area, and more accurately This has the effect that the emergency call reception center in charge can be obtained. In particular, the emergency call reception center of the appropriate jurisdiction automatically obtained from the transmission position received from the mobile terminal is recorded in the storage means without the operator manually determining the emergency call reception center of the jurisdiction. .

  Storage means can be stored in a private branch exchange memory, hard disk, etc., can be stored in a communication apparatus memory, hard disk, etc., or can be stored in a memory other than the private branch exchange and communication apparatus, hard disk, etc. It is. Of course, the database may be constructed on a device other than the private branch exchange, the computer on which the telephone device is constructed, the private branch exchange, and the telephone device.

  (3) The emergency call method according to the present invention includes a calling process in which a portable terminal sends an emergency call, and a private branch exchange of the emergency call reception center determined by route determination as necessary. A call path forming process for forming a call path, a manual transfer process for transferring to a private branch exchange in an emergency call reception center having jurisdiction determined by a transfer operation of an operator who operates the call device, and a transfer in the manual transfer process The private branch exchange of the emergency call reception center, which has been manually transferred, forms a call path with the call device of the emergency call reception center, and the transfer operation of the operator who operates the call device by the emergency call reception center in charge If determined, base station identification information of a base station that is a communication facility of a carrier network that has received a radio wave from a portable terminal at the time of outgoing call and A sector originating mobile terminal during was located emergency call, is intended to include the manual transfer rules forming step of recording in the storage means in association with the emergency call receiving center which is determined by the transfer operation of the operator.

  As described above, in the present invention, the emergency call reception center transferred in the manual transfer step and the identification information of the base station that has received the radio wave from the mobile terminal at the time of emergency call transmission and the emergency call transmission at the base station Since the mobile terminal is associated with the sector in which the mobile terminal is located and recorded in the storage means, for example, the operator determines the emergency call reception center in charge based on information heard by the operator through a call with the user, and the emergency call A call path is formed with the call device in the reception center, so that the emergency call reception center in charge can be obtained more accurately.

  (4) The emergency call method according to the present invention is a carrier network communication facility in which the private branch exchange of the emergency call reception center determined by route determination receives radio waves from a mobile terminal when an emergency call is made, as necessary. A process for reading out the emergency call reception center that matches in the storage means between the base station identification information of the base station and the sector where the mobile terminal was located when the emergency call was transmitted, and identifying the emergency call reception center in charge is newly added. If the emergency call reception center specified in the relevant process is the same as the emergency call reception center determined by route determination, a communication path is formed with the call device in the emergency call reception center determined by route determination. If the emergency call reception center specified in the relevant process is not the same as the emergency call reception center determined by the route decision, The private branch exchange in the emergency call reception center determined by the decision is transferred to the private branch exchange of the emergency call reception center that has jurisdiction, and the transferred private branch exchange in the emergency call reception center calls the emergency call reception center. A communication path is formed with the device.

Even if an emergency call is made using a portable terminal that does not have, the caller can talk to the operator of the emergency call reception center in charge without being transferred.

(5) The emergency call method according to the present invention newly includes a step in which the storage means provided in each emergency call reception center is mutually updated as necessary.
As described above, in the present invention, the information recorded in the storage means of each emergency call reception center in (2) or (3) is also reflected in the storage means of other emergency call reception centers. Even if an emergency call is made from a location where the communication facility of the emergency call reception center has never formed a communication path in the past, any other emergency call reception center has Is included in the shared transfer rule, and the transfer can be appropriately performed using the transfer rule.

  In the case of updating, the storage means is composed of, for example, database servers, and the database servers are automatically updated via the network, and the private branch exchange in the emergency call reception center is replaced with the private branch exchange in another emergency call reception center. It is also possible to adopt a configuration in which data is updated by receiving data read from the storage means.

  (6) The emergency call method according to the present invention includes, as necessary, an emergency call reception center transferred in the transfer step and a communication facility of a carrier network that has received radio waves from a mobile terminal when the emergency call is transmitted. In the manual transfer rule forming process in which the base station identification information of a certain base station and the sector for the base station where the mobile terminal was located when the emergency call was transmitted are recorded in the storage means, the mobile terminal transmits the emergency call. In the case where there are a plurality of specified emergency call reception centers, when the emergency call reception center in charge is specified, the current emergency call transmission time is within a predetermined time. The private branch exchange in the emergency call reception center determined by route determination determines whether there is only one emergency call reception center that has received an emergency call exceeding the first threshold. If it is determined that there is only one emergency call reception center that has received an emergency call exceeding the first threshold value within a predetermined time in the process, the premises of the emergency call reception center determined to be only one The exchange forms a call path between the call device in the emergency call receiving center and the portable terminal that has received an emergency call equal to or greater than the first threshold within the predetermined time.

Thus, the present invention can grasp the invention as a system.
These outlines of the invention do not enumerate the features essential to the present invention, and a sub-combination of these features can also be an invention.

  Throughout the embodiments, the same elements are assigned the same numbers and steps, and the elements are the same unless otherwise described.

(First embodiment of the present invention)
FIG. 1 is a system configuration diagram of an emergency call system according to the present embodiment. In the figure, 1 is a portable terminal, 2 is a carrier network, 21 and 22 are base stations, 31 and 51 are communication devices, 32 and 52 are private branch exchanges, and 4 and 6 are database search devices. 3 and 5 are emergency call reception centers. 21 a is an area of the base station 21, and 22 a is an area of the base station 22. Reference numeral 80 denotes an administrative division line.

  The mobile terminal 1 is a mobile phone, and forms a communication path with the target fixed telephone and other mobile phones via the carrier network 2 including the base stations 21 and 22. The portable terminal 1 includes a display unit of a liquid crystal display, a button for inputting a transmission number, a call button, a disconnect button, a speaker for outputting sound, a microphone for inputting sound, a communication unit for receiving / transmitting radio waves and processing communication, and a caller It consists of a GPS receiver that acquires the current position and a control unit that controls each component. Here, the GPS (global positioning system) is a system that receives radio waves transmitted from an artificial satellite and measures the longitude and latitude and altitude of the current position. The GPS receiver receives the radio waves. There are already mobile phones equipped with GPS receivers, and since they are well-known technologies, a detailed description is omitted.

  The carrier network 2 is a network owned by a telecommunications carrier and includes communication equipment such as an exchange. The communication equipment used in the carrier network differs depending on the carrier, but if it is exemplified in the mobile communication network, it has a base station, a mobile communication exchange and a gateway exchange, and if exemplified in the fixed telephone network, it is a subscriber exchange, relay exchange, and Has a gateway exchange. The mobile communication network and the fixed telephone network are connected by a point of interface (POI).

  The base stations 21 and 22 are also communication facilities of telecommunication carriers that are carriers, communicate with the mobile terminal 1 by radio waves, and connect to the communication facilities (line control stations and exchanges) of the carrier network 2 in a wired manner. ing. A range in which radio waves reach centering on the base stations 21 and 22 is referred to as a zone, and arranging a plurality of base stations 21 and 22 to form a zone and configuring a service area is referred to as a zone method or a cell method.

  The communication devices 31 and 51 are terminals operated by an operator, which are communicably connected to the private branch exchanges 32 and 52, and enable communication between the caller and the operator via a headset integrated with headphones and a microphone. It is. The terminal also has a keyboard and a display, and an operator can input the contents of a report from a person who is familiar. Specifically, a communication device for connection to the private branch exchanges 32 and 52 is arranged in a general computer. When the private branch exchanges 32 and 52 and the communication devices 31 and 51 are connected via LAN, the communication device is a LAN card. The call devices 31 and 51 have various programs installed therein, a function for receiving a call, a function for displaying information on a caller (caller number, call position information) on a display when receiving a call, and various call contents A function for receiving and displaying a call, a function for making a call, and a function for transmitting information related to an emergency call such as information related to a caller and various types of input calls.

  The private branch exchanges 32 and 52 are devices installed in the emergency call reception centers 3 and 5 to perform exchange connection of extension telephones and exchange connection with external general telephones (cell phones and fixed telephones). In the present embodiment, exchange connection between the communication devices 31 and 51 and an external general telephone is performed. Specifically, when a connection request from the exchange of the carrier network 2 to the private branch exchanges 32 and 52 is made, the private branch exchanges 32 and 52 call one of the call devices 31 and 51, and the call devices 31 and 51 respond. Then, a response is detected on the exchange side, a communication path is formed, and communication becomes possible. On the other hand, when the communication devices 31 and 51 make a call, the private branch exchanges 32 and 52 detect the call, the private branch exchanges 32 and 52 receive the number, the number is sent to the exchange of the carrier network 2, and the telephone of the corresponding number is called. When a response is made, the response is detected on the exchange side, and a communication path is formed to enable a call.

  Further, the private branch exchanges 32 and 52 can obtain the emergency call reception centers 3 and 5 of the responsible administrative district from the transmission position information that can be acquired at the time of the incoming call. As a specific example, if the transmission position information is longitude and latitude, an address can be obtained from the longitude and latitude, and the emergency call reception centers 3 and 5 of the responsible administrative district can be obtained from the address. For example, “2-2-1 Hyakumichihama, Sawara-ku, Fukuoka City” can be obtained from “latitude: 33 degrees 35 minutes 33.263 seconds, longitude: 130 degrees 21 minutes 17.932 seconds”.

The database search devices 4 and 6 are devices for recording, reading and searching data. In the present embodiment, the caller number, the transmission position information, and the report contents are data targets.
FIG. 2 is an explanatory diagram of an operation state of the emergency call system according to the present embodiment.

A disaster occurs in City A, and the owner of the mobile terminal 1 inputs an emergency call telephone number (110, 119, 118, etc.) to make a call. The mobile terminal 1 is in the area 22 a and makes a call via the base station 22. At the time of this call, the portable terminal 1 transmits the transmission position information consisting of latitude and longitude using a GPS receiver.
The carrier network 2 generates a path to the emergency call reception system 3 in a predetermined administrative district for the outgoing call, and records the received transmission position information in a database in the network.
When an emergency call is received, the private branch exchange 32 requests the carrier network 2 to notify the caller information related to the emergency call, acquires the caller's caller number, caller location information, etc. accumulate.
The private branch exchange 32 refers to the database search device 4 to derive an address from the transmission position information and determines whether or not it is a responsible administrative district. If the result of the determination is that the administrative district is in charge, the private branch exchange 32 performs exchange connection with any one of the call devices 31 in the emergency call reception center 3. If it is not the responsible administrative district as a result of the determination, the private branch exchange 32 acquires the emergency call reception system 5 of the responsible administrative district with reference to the database search device 4 and performs automatic transfer processing to the emergency notification reception system 5 of the responsible administrative district. Further, the private branch exchange 32 transmits the caller information related to the automatic transfer to the database search device 6 via the private branch exchange 52 of the emergency call reception system 5 of the responsible administrative district. By being automatically transferred, a call path between the call device 51 and the portable terminal 1 is formed, and an operator and a caller can talk. During a call, the call device 51 reads caller information related to the current call from the position information database 6 and displays it on the display unit.

  As described above, according to the emergency call system according to the present embodiment, the owner of the mobile phone 1 is in the administrative city A city, and the base station 22 in the area 22a to which the mobile phone 1 belongs is different from the A city in the administrative city B city. If the owner enters the emergency call number into the mobile phone 1 and makes a call, the pass is established with the emergency call reception system 3 in the city B where the base station 22 is located, and at the same time the call is carried The private branch exchange 32 obtains the caller ID and the call location information received by the carrier network 2 from the telephone 1, and determines whether or not it is the responsible administrative district by referring to the database search device 4, and determines that the administrative district is not the responsible administrative district. Since the call is automatically transferred to the emergency call reception system 5, the caller may be the first caller to be the operator of the responsible administrative district, and the operator who is not in charge of the administrative district may be calling. Unlike conventional systems, smooth notifications are exchanged. On the other hand, for the operator, the operator is also a caller who is in the responsible administrative district and a caller from outside the responsible administrative district The private branch exchange 32 automatically transfers to the private branch exchange 52 of the emergency call reception system 5 of the responsible administrative district where the caller is located instead of the manual transfer by the telephone, saving the trouble of the manual transfer to the private branch exchange 52 that has been conventionally performed manually. It is burned.

  In the emergency call reception system according to the present embodiment, the private branch exchange 32 determines whether or not the current call is a call from the administrative district in charge, but other devices (for example, a database) of the emergency call reception system 3 The search apparatus 4) may make such a determination, and the private branch exchange 32 may automatically transfer. However, since the private branch exchange 32 serves as an interface for the emergency call reception system, it is desirable for the private branch exchange 32 to make such a determination from the viewpoint of quick processing. Although the database search device 4 is referred to, it is desirable that information necessary for the determination is expanded in the memory in the activated state of the private branch exchange 32 from the viewpoint of quick processing.

(Second embodiment of the present invention)
The same elements as those in the first embodiment are given the same numbers, and the elements not described separately are the same.
FIG. 3 is a system configuration diagram of the emergency call system according to the present embodiment.
Unlike the portable terminal 1 of the first embodiment, the portable terminal 7 does not include a GPS receiver. Therefore, transmission position information cannot be transmitted from the mobile terminal 7 to the carrier network 2.

  The base stations 21 and 22 have a caller ID that can uniquely identify the caller with respect to the mobile switching center that is a communication facility of the carrier network 2, and a base station ID and area that can uniquely identify the base station. Sector information that can uniquely identify a sector substantially defined by dividing the circumferential angle at the center within the area is transmitted. Normally, the sector configuration of the base stations 21 and 22 is 6 sectors and 3 sectors. The reason why it is possible to determine which sector in the area where the base stations 21 and 22 are within the reception range is because the antennas of the base stations 21 and 22 have directivity.

In the present embodiment, for convenience of explanation, the current emergency call transfer procedure will be described, and then the emergency call transfer procedure according to the present invention will be described.
FIG. 4 is an explanatory diagram of the current emergency call transfer procedure of the emergency call system.

When the caller is in the administrative district of A city and the mobile terminal 7 is in the sector 5 of the area 22a of the base station 22 arranged in the vicinity of the administrative division line, the location information is acquired without being equipped with a GPS receiver. An emergency call is made from the mobile terminal 7 that cannot.
The base station 22 receives the call, requests the mobile switching center to be connected to the mobile switching center, and transmits the caller ID, the base station ID of the base station, and sector information to the mobile switching center.
The mobile switching center registers the caller ID, the base station ID of the base station, and the sector information, and makes a call setting request to the other communication equipment of the carrier network 2.
The communication facility of the carrier network 2 generates a path to the emergency call reception center 3 in a predetermined administrative district in response to the call setting request, and a communication path is formed between the mobile terminal 7 and the communication device 31 via the private branch exchange 32. The

The operator has a conversation with the caller and asks for a report type (type 119: “fire” or “emergency”), name, telephone number, and current location (disaster location). When the current position is found out, the operator determines whether or not he / she is in charge of his / her own administrative district, and if not, he / she uses the communication device 31 for the emergency call reception center 5 in the administrative district which has jurisdiction over the current location of the caller. Manual transfer.
A communication path is formed between the caller and the call device 51 of the emergency call reception center 5 of the appropriate administrative district through the private branch exchange 32 and the communication network 2 of the carrier network 2, and the caller and the operator of the emergency call reception center 5 call. To do. Along with the formation of the communication path, the private branch exchange 52 makes a caller ID request and a call origination location request to the communication equipment and the mobile switching center of the carrier network 2, respectively. Receives base station ID and sector information from the facility.

  FIG. 5 is an explanatory diagram of an emergency call transfer and registration procedure of the emergency call system according to the present embodiment. This figure is the same until manual transfer by the operator of FIG. 4 (the part above the dotted line in FIG. 5 is the same as the corresponding part of FIG. 4), and the subsequent procedure will be described.

  The private branch exchange 32 makes a caller ID request and a call origin location request (base station and sector information) to the communication equipment of the carrier network 2 and the mobile switching center, respectively. The base station ID and sector information from the communication facility are received. The private branch exchange 32 registers the received base station ID and sector information and the manual transfer destination emergency call reception center in the database 4.

  At substantially the same time as the registration in the database, a call path between the caller and the call device 51 of the emergency call reception center 5 manually transferred is formed, and the caller and the operator of the emergency call reception center 5 make a call. The caller ID, base station, and sector information can be acquired from the communication equipment of the mobile switching center and the carrier network 2 or the emergency call reception center 3.

  FIG. 6 is an explanatory diagram of an emergency call transfer procedure of the emergency call system according to the present embodiment. This figure is the same up to the call setup request shown in FIG. 5, and the subsequent procedure will be described. Here, the portion above the dotted line in FIG. 6 is the same as the corresponding portion in FIG. The description will be made on the assumption that data has already been stored in the registration in the database 4 described in FIG. That is, in this embodiment, the transfer destination rule for manual transfer is stored in the database 4 in the procedure of FIG. 5, and the transfer destination rule is used according to the procedure of FIG.

  The private branch exchange 32 makes a caller ID request and a call origin location request (base station and sector information) to the communication equipment of the carrier network 2 and the mobile switching center, respectively. The base station ID and sector information from the communication facility are received. The private branch exchange 32 refers to the base station ID and sector information already received with respect to the database 3 as keys. As a result of the reference, the emergency call reception center 5 of the transfer destination is obtained, and the private branch exchange 32 transfers the emergency call reception center 5 to the emergency call reception center 5. After the transfer, a call path between the caller and the call device 51 of the emergency call reception center 5 manually transferred is formed, and the caller and the operator of the emergency call reception center 5 make a call. In accordance with the call, the caller number and the place of transmission are transmitted from the database 4 of the emergency call reception center 3 of the transfer source to the database 6 of the emergency call reception center 5. Here, as a result of referring to the database 3, when the corresponding base station ID, sector information, and emergency call reception center are not manually registered and registered by the operator, the emergency call currently being processed without being transferred A communication path is formed in the call device 31 of the reception center. At this time, the emergency call reception center handled by the database 3 as a default in the database 3 is stored in advance as a transfer destination emergency call reception center, and the base station ID, sector information, and emergency call reception center are stored by manual transfer. In some cases, the emergency call reception center may be updated.

(Other embodiments)
[Register to database]
In the first embodiment, the call location information is obtained, the location where the caller is present is accurately determined, and the emergency call reception center having the location as the jurisdiction and the communication path are formed. As in the second embodiment, the base station ID and sector information can be acquired, and can be registered in the database 4 in association with the emergency call reception center where the call path is formed. Therefore, the transfer rule is registered and the manual transfer of the operator can be reduced.

[Mutual database update]
In each of the above embodiments, registration in the database is registered only for the emergency call reception center to which the operator belongs by manual transfer of the operator, but the registration contents are periodically updated between the emergency call reception centers. (See FIG. 7). By doing so, when the registration to the database has been completed because the emergency call reception center with manual transfer has been completed, manual transfer related to the same base station ID and sector information is performed at the other emergency call reception centers by the operator. The emergency call reception center associated with the base station ID and the sector information is registered in the database even if it is not implemented by the above, and a call path can be formed to the emergency call reception center in the appropriate administrative district.

Here, it is desirable to register in the database even when transfer is not performed (in this case, it is possible to distinguish between the case where there is a past call and the case where there is no call). Specifically, the content registered in the database will be described as an example. The database attributes include a base station, sector information, a transfer source, and a transfer destination. Here, the transfer process can be performed even without the transfer source attribute. Assume that the database stores all combinations of base station and sector information in advance. For conditions that have not been received so far, the values of the transfer source and transfer destination are “−” (see FIGS. 8B and 1). When a communication path is formed in the telephone device of the emergency call reception center that is transferred under the condition that the call has been received so far, the value of the transfer destination is “x” (FIG. 8B ( See 2)). When it is transferred under the condition of receiving a call, the value of the transfer destination is the transfer destination (see FIGS. 8B and 3). When the databases are configured in this way, when the databases are mutually updated, there are times when different transfer destinations are associated with the same base station and sector information. This is a case where the same sector area is under the jurisdiction of a plurality of administrative districts, which means that emergency situations such as fires have occurred in the past in each of the plurality of administrative districts. For such a combination, it is desirable to stop the mutual update of the database and change from automatic transfer to manual transfer. Therefore, when the forced manual transfer attribute is set in the database and the forced manual transfer flag is set for the combination in which the jurisdiction conflicts, the private branch exchange refers to the database and the forced manual transfer flag is set. It is desirable to form a communication path with the operator on the premises without transferring, and to manually transfer if necessary.
Although the mutual update of the database has been explained, there is no need for mutual update when all the emergency call reception centers share one database, but the registration of the database by each campus exchange is the same as the one described above. Must be done for one database.

  [Statistical Judgment] As shown in FIG. 8C, in a database in an emergency call reception center, a communication path is formed with a telephone device of a different emergency call reception center for the same base station and sector information. Cases arise. However, compared with FIG. 8B, the attribute of the transmission date and time (the incoming date and time, the transfer date and time, and the utterance date and time) may be added to this database. It has already been explained that there are cases where the destinations for forming speech paths are different depending on the conditions of the same base station and sector information in the past when the same sector area is under the jurisdiction of multiple administrative districts. . Normally, it is rare for multiple emergency situations to occur within the same sector area, and as shown in FIG. This is because there is an emergency call about the same fire from a plurality of different callers at the same time when a fire occurs. Accordingly, when one or more transmissions are made and the combination is registered in the database, and when the base station, the sector information, and the destination for forming the speech path are the same, a predetermined time (for example, 1 hour, 1 hour). It is desirable that the destination of the call path is determined according to the combination of the fire engines. By doing so, if emergency calls outside the responsible administrative district occur frequently, the emergency call reception center can avoid the congestion of the business and does not interfere with the emergency notification of the responsible administrative district.

  Furthermore, if the destination of the call path within a predetermined time is not yet registered in the database, the base station, sector information, and the call path are formed within a predetermined time (for example, one hour) from the combination registered at a certain date and time. It is desirable to form a speech path with a speech path formation destination of the combination having the largest ratio even if the ratio calculation is performed after regarding the combination having the same destination as one. This is because when an innumerable number of emergency calls are made for an incident and a small number of other emergency calls are made, the specific gravity of the incident is increased, and the countless number of emergency calls for an incident increases. This is to prevent the transfer destination from being always selected as the transfer destination. Here, when all the ratios are the same, manual transfer is performed. In the case of FIG. 8 (c), one case within 1 hour from “03:13 on March 13, 1990” and 2 within one hour from “10:31 on October 3, 1990”. There are 4 cases within 1 hour from "23:10 on February 1, 2003" and 3 cases within 1 hour from "August 1, 2005 21:14", but each is regarded as one. , “March 13, 1990, 10:31” and 25% of cases where a communication path is established with the telephone device of the emergency call reception center, “October 3, 1990, 10:31” Is transferred to C from 25 [%], and is transferred from 50 to 23:10 on February 1, 2003 and from 21:14 on August 1, 2005 to 50 [ %]. Therefore, in this case, the data is automatically transferred to the transfer destination B having the highest ratio of 50 [%]. Here, when automatic transfer is performed, if the maximum ratio is equal to or less than a predetermined threshold value, manual transfer may be employed. For example, when the threshold is set to 80 [%] and in the case of FIG. 8C, manual transfer is performed.

  [Determination of Call Path Formation Destination Based on Base Station, Sector Information and Distance Information] As shown in the second embodiment, it is more appropriate to determine a call path formation destination by a sector further narrowing down the base stations. You can talk to the report reception center. Here, in addition to the base station and sector information, the location of the caller is further limited based on the distance information from the base station, and the speech path formation destination is determined. The distance information from the base station can be roughly calculated from the radio wave intensity received by the mobile terminal from the base station. Therefore, the radio field intensity and distance information obtained at the base station or mobile terminal is transmitted to the private branch exchange that determines the destination of the call path, and the private branch exchange receives the base station, sector information, and distance information (when the received information is the radio field intensity). In this case, the communication path forming destination is determined based on the distance information. At this time, the radio field intensity received by the mobile terminal from the base station is used, but the radio field intensity received by the base station from the mobile terminal may be used. By doing so, even if the base station, the sector information, and the time zone are the same, there is a high possibility that a more appropriate emergency call reception center and the caller form a communication path due to the difference in distance information (see FIG. 8 (d)).

[Reflection of erroneous transfer] The emergency call reception system according to each of the above embodiments determines that a call automatically transferred by the present system is erroneously transferred by an operator of the emergency call reception center of the automatic transfer destination based on a call with the caller. In such a case, by notifying the telephone equipment that it is an erroneous transfer, the private branch exchange that has transferred via the transferred private branch exchange receives the notification and prohibits the re-execution of the transfer. You can also. Specifically, the base station information, sector information, and emergency call reception center combination used to determine the automatic forwarding destination are registered in the automatic forwarding judgment prohibition reference list, and the private branch exchange derives the forwarding destination judgment. In this case, the transfer to the transfer destination derived when the automatic transfer determination prohibition reference list is introduced and matched is stopped, and a communication path connected to the private branch exchange is formed.
In addition, the private branch exchange may collect information related to erroneous transfer and display the information on the call device according to the operation of the operator.
Further, the private branch exchange can be configured so that the operator correctly sets the information related to erroneous transfer using the communication device and updates the private branch exchange information.

  [Sender ID] In each of the above-described embodiments, the caller ID is first notified to the private branch exchanges 32 and 52. Alternatively, the caller ID may be notified instead. . In that case, it is not necessary to make a caller request in a later process. The reason why the caller ID, not the caller ID, is first notified to the private branch exchanges 32 and 52 is that the conventional emergency call operation procedure is so prescribed.

  Although the present invention has been described with the above embodiments, the technical scope of the present invention is not limited to the scope described in the embodiments, and various modifications or improvements can be added to these embodiments. . And embodiment which added such a change or improvement is also contained in the technical scope of the present invention. This is apparent from the claims and the means for solving the problems.
