Description

  The present invention relates to an exchange.

  In recent years, mobile phones have become widespread, and the use of telephones on the go has expanded, and mobile telephones have come to be used even when making emergency calls to the police or fire department on the go.

  In general, when an emergency call is originated from a mobile phone, a technology for adding a preset area code (emergency area code) to the base station on the base station side receiving the emergency call is considered. It has been. In this case, on the exchange network side of the telephone line that receives the emergency call from the base station, it is possible to determine to which police station or fire station the emergency call is connected by using the area code.

  Conventionally, there has been known a technique for notifying a caller of a message corresponding to a case where the other party is unknown by voice when the other party is unknown when the caller makes a call (for example, , See Patent Document 1).

Japanese Patent Laid-Open No. 2-72756

  However, at present, the number of base stations to which area codes are added is limited, and there are base stations that do not have a function to add area codes. When a mobile phone user communicating with such a base station makes an emergency call to contact the police or fire department, the exchange determines which police station or fire department should be notified. Can not. In this case, as in the conventional example described above, it is impossible to deal with an emergency situation by notifying that the other party is unknown by a voice message.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an exchange capable of performing processing in consideration of a call to which no area code is added.

  A first aspect of the present invention is an exchange, which is connected so as to be accessible to a database that stores an area code and a telephone number to be contacted in association with each other, and when the telephone number is received from the terminal side, A communication detector for connecting a communication to a number; and the communication detector receives an area code together with the telephone number and determines whether the area code is stored in the database. An arithmetic processing unit that transmits an alarm to a predetermined transmission destination when it is determined that the code is not received or the received area code is not stored in the database.

  Here, the area code may be a code corresponding to the telephone number of the police headquarters that supervises the police station having jurisdiction over the installation location of the base station.

  The predetermined transmission destination may be a monitoring device of a telecommunications carrier that manages and manages the exchange, and the monitoring device may store an area code in a database in the exchange.

  It should be noted that the above summary of the invention does not enumerate all the necessary features of the present invention. In addition, a sub-combination of these feature groups can also be an invention.

It is a block diagram which shows roughly an example of the communication system containing the exchange which concerns on embodiment of this invention. It is a block diagram showing roughly an example of composition of an exchange concerning an embodiment of the invention. It is explanatory drawing showing the example of the content of the area code database referred by the switching system which concerns on embodiment of this invention. An example of the flow of communication processing using the exchange concerning an embodiment of the invention is shown roughly.

  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a block diagram schematically illustrating an example of a communication environment of a communication system. A wireless communication terminal 1 (hereinafter referred to as terminal 1) is connected to a wireless communication network 5 via a base station 3. A wireless communication terminal 2 (hereinafter referred to as terminal 2) is connected to a wireless communication network 5 via a base station 4. In the present embodiment, it is assumed that an area code described later is set in a part of the base station 3, and the base station 3 in which the area code is set stores the area code.

  The base station 3 communicates wirelessly with a wireless communication terminal located within its own communication range. For example, when the terminal 1 is located within the communication area, when there is a call request from the terminal 1 side, the telephone number of the other party received at the time of the request is sent to the exchange 6 in the exchange network 60. At this time, if the base station 3 stores the area code, the base station 3 sends the destination telephone number to the exchange 6 together with the area code. Furthermore, the base station 3 holds identification information for identifying itself, and when the information is transmitted to the exchange 6 side, the identification information is also transmitted.

  An exchange network 60 including a plurality of exchanges 6 is provided in the wireless communication network 5, and the exchanges 6 in the exchange network 60 connect communications from the base stations 3 and 4 to each other. For example, when communication connection is made from the terminal 1 to the terminal 2, a transmission signal from the terminal 1 is transmitted to one of the exchanges 6 in the wireless communication network 5 via the base station 3. The exchange 6 confirms the telephone number of the terminal 2 included in the transmission signal from the terminal 1, connects to the base station 4 via the exchange 6 in the exchange network 60, and calls the terminal 2.

  Such an operation of the exchange network 60 is widely known as a call connection operation, and thus detailed description thereof is omitted here.

  When the terminal 2 responds to the call, the terminal 1 and the terminal 2 can communicate with each other through the base station 3, the switching network 60, and the base station 4. In FIG. 1, 7 is a gateway exchange, 8 is a fixed communication network, and 9 and 10 are fixed telephones. Reference numeral 110 denotes an exchange network provided in the fixed communication network, and includes a plurality of fixed network side exchanges 11.

  The gateway exchange 7 connects between the wireless communication network 5 and the fixed communication network 8. The gateway exchange 7 enables communication between the terminals 1 and 2 and the fixed telephones 9 and 10 connected to the fixed communication network 8. Specifically, calls from the terminals 1 and 2 are connected to the fixed telephones 9 and 10 via the wireless communication network 5, the gateway exchange 7, and the fixed communication network 8. As an example, when communicating from the terminal 1 to the fixed telephone 10, a transmission signal from the terminal 1 is transmitted to the exchange 6 of the wireless communication network 5 via the base station 3. The exchange 6 identifies the telephone number of the fixed telephone 10 included in the outgoing signal from the terminal 1 as the telephone number on the fixed communication network 8 side, and the fixed network side exchange 11 in the fixed communication network 8 via the gateway exchange 7. A communication path is established between the telephone number and the telephone number is transmitted. The fixed network side exchange 11 identifies the telephone number of the fixed telephone 10 and performs call connection processing with other fixed network side exchanges 11 in the exchange network 110, establishes a communication path to the fixed telephone 10 and establishes the fixed telephone. Connect the call to 10. Thus, when the fixed telephone 10 responds to the connection from the fixed network side exchange 11, the communication between the terminal 1 and the fixed telephone 10 becomes possible.

  Reference numeral 12 denotes a monitoring device that changes the settings of various information stored in the exchange 6. The monitoring device 12 is a device managed by a telecommunications carrier that manages and operates the base station 3 and the wireless communication network 5.

  FIG. 2 is a block diagram showing a configuration example of the exchange 6 according to the embodiment of the present invention. The exchange 6 includes a CPU 21, a ROM 22, a RAM 23, a communication detection unit 24, and an arithmetic processing unit 25.

  The CPU 21 operates using the information stored in the RAM 23 according to the program stored in the ROM 22 to control the communication detection unit 24 and the arithmetic processing unit 25. The CPU 21 is connected to an area code database 26 in which the area code is associated with a telephone number as a communication destination. Specifically, the area code database 26 may be stored in the RAM 23 or may be recorded in a database server connected via a network (not shown) and accessible from the CPU 21. .

  The communication detection unit 24 performs communication with the base station 3 and other exchanges 6. Specifically, when the communication detection unit 24 receives a call request from the terminal 1 via the base station 3, for example, a call request to the terminal 2, the communication detection unit 24 sets a connection destination (telephone number) of the call related to the request. If the telephone number is a telephone number of a terminal communicating with another base station 4 belonging to the same wireless communication network 5 in accordance with an instruction from the arithmetic processing unit 25, the detected number is output to the arithmetic processing unit 25. In cooperation with the other exchange 6, a communication path to the base station 4 is established, and the counterpart terminal 2 connected via the base station 4 is called. As a result, communication between the terminal 1 and the terminal 2 connected via the wireless communication network 5 becomes possible.

  The communication detecting unit 24 is connected to a terminal connected to the wireless communication network 5 and another communication network, for example, a fixed telephone connected to the fixed communication network 8 or a wireless communication network different from the wireless communication network 5. Implements call connection control with terminals.

  As an example, when receiving a call request from a terminal to a fixed telephone connected to the fixed communication network 8 as another communication network from the terminal via the base station 3, the communication detection unit 24 is connected to the call destination related to the request. (Telephone number) is detected and output to the arithmetic processing unit 25, and the telephone number is the number of the fixed telephone connected to the fixed communication network 8 according to an instruction from the arithmetic processing unit 25. Then, a call connection request is made to the exchange network 110 on the fixed communication network 8 side. When a call connection with the other party's fixed telephone is made on the switching network 110 side, a communication path with the other party's fixed telephone is established through the connected call, and a call between the terminal and the fixed telephone is enabled.

  Furthermore, in the example of the present embodiment, the communication detection unit 24 receives the telephone number related to the call request from the base station 3 to which the terminal 1 that has made the call request is connected, and the arithmetic processing unit 25. Output to. At this time, when the area code is accepted from the base station 3, the area code is output to the arithmetic processing unit 25 together with the telephone number.

  The arithmetic processing unit 25 is connected to the telephone (or terminal) having the telephone number input from the communication detecting unit 24 through the gateway exchange 7 as to whether the telephone (or terminal) communicates with the base station 3 in the wireless communication network 5. It is determined whether the communication network is of another communication network, and the determination result is output to the communication detection unit 24. Note that the arithmetic processing unit 25 can communicate with which base station 3 in the wireless communication network 5 (if which base station 3 is currently communicating) if the terminal communicates with the base station 3 in the wireless communication network 5. And the base station 3 capable of communicating with the counterpart terminal is output to the communication detector 24.

  The arithmetic processing unit 25 also checks whether the telephone number input from the communication detection unit 24 is a predetermined number, for example, a number related to an emergency call. Specifically, in Japan, the number related to the emergency call is “110”, which is the connection number to the police station, “119”, which is the connection number to the fire department.

  If the telephone number input from the communication detection unit 24 is a predetermined number, the arithmetic processing unit 25 checks whether there is area code information received from the base station 3, and the area code information is If there is, the area code database 26 is accessed to check whether the area code received from the base station 3 is stored in the area code database 26.

  Here, if the area code received from the base station 3 is stored in the area code database 26, the arithmetic processing unit 25 refers to the telephone number stored in the area code database 26 in association with the area code. In an example of the present embodiment, the area code database 26 is a telephone to be called in association with the area code and the telephone number (calling number) transmitted from the base station 3 as illustrated in FIG. The number is registered. Specifically, in the example of FIG. 3, the police in the area where the base station 3 identified by the area code A is associated with the area code A and the telephone number “110” that can be transmitted from the base station 3 side. An example in which a telephone number X of a station is registered is shown. Similarly, in association with this area code A and the telephone number “119” that can be transmitted from the base station 3, the telephone number Y of the fire station in the area where the base station 3 identified by the area code A is arranged is registered. It is supposed to be.

  The arithmetic processing unit 25 obtains a telephone number to be called, which is stored in the area code database 26 in association with the area code and telephone number input from the base station 3. The arithmetic processing unit 25 instructs the communication detection unit 24 to connect the call to the subscriber specified by the obtained telephone number instead of the telephone number transmitted from the base station 3 side.

  When the area code received from the base station 3 is not stored in the area code database 26, the arithmetic processing unit 25 issues an alarm by a predetermined method. Specifically, this alarm is issued by transmitting alarm information to the monitoring device 12. The monitoring device 12 that has received the alarm information notifies the administrator that the alarm has been notified.

  Note that the information registered in the area code database 26 in this example may be set and stored by an operation from the monitoring device 12. Further, in the area code database 26, information (for example, latitude / longitude information) of a position where the base station 3 identified by the area code is located may be registered in association with the area code.

  The exchange 6 according to the present embodiment has the above-described configuration and operates as follows. Hereinafter, the operation of the communication system including the exchange 6 according to the present embodiment will be described using FIG. 4 as an example in which the terminal 1 makes an emergency call.

  When the terminal 1 transmits an emergency call, for example, “110” in S <b> 1, the base station 3 in which the terminal 1 is within the communicable area receives the emergency call from the terminal 1. In S <b> 2, the base station 3 transmits “110”, which is an emergency contact number, and an area code set in advance to itself, for example, “A”, to the exchange 6.

  The exchange 6 receives these telephone numbers and area codes, and the arithmetic processing unit 25 of the exchange 6 recognizes the emergency call destination telephone number “110” received from the base station 3, and receives the area code in S3. Check if you did.

  Here, since the area code is received, the arithmetic processing unit 25 of the exchange 6 accesses the area code database 26 and checks whether or not the received area code is registered in the area code database 26.

  Here, it is assumed that the received area code is registered in the area code database 26. In S4, the arithmetic processing unit 25 of the exchange 6 extracts the same area code “A” as the received area code and the telephone number associated with the telephone number “110”, and sends the telephone number to the communication detecting unit 24. Output. Here, it is assumed that the extracted telephone number is the telephone number of the police station in the area where the base station 3 is located.

  The communication detection unit 24 of the exchange 6 makes a call to the input telephone number. As a result, the terminal 1 and the telephone of the police station having jurisdiction over the area where the terminal 1 is located are connected for communication.

  On the other hand, if the area code is not set in the base station 3, the base station 3 transmits only the telephone number “110” transmitted by the terminal 1 to the exchange 6 in S2.

  In this case, in S3, the arithmetic processing unit 25 of the exchange 6 determines that no area code has been received. In S 5, the arithmetic processing unit 25 of the exchange 6 transmits an alarm to the monitoring device 12 indicating that the emergency call has been received but there is no area code. Even when the area code received in S4 is not registered in the area code database 26, the arithmetic processing unit 25 of the exchange 6 receives an emergency call, but indicates that the area code is not registered in the area code database 26. An alarm is transmitted to the monitoring device 12.

  In S6, the monitoring device 12 that has received this alarm presents information to the administrator that an emergency call cannot be made. Further, in this example, the exchange 6 accepts information (such as identification information of the base station 3) specifying the base station 3 from which the telephone number related to the emergency call is input from the base station 3, and sends it to the monitoring device 12 together with an alarm. May be.

  In this case, the monitoring device 12 holds the identification information of each base station in advance in association with the location information such as latitude and longitude, which is the installation location, and associates it with the identification information of the base station 3 that is held. The obtained location information may be provided to the administrator. Based on this information, the administrator instructs the switch 6 to connect the call to the telephone number to which the emergency call is connected (such as the telephone number of the police station having jurisdiction over the area where the base station 3 is located). To do.

  In this case, if the area code is not set in the base station 3, the administrator may set the area code for the base station 3 based on the notified latitude and longitude (S7). ). Similarly, if the area code is not registered in the area code database 26, the area code and the corresponding telephone number are registered in the area code database 26.

  In this example, the area code may be a code (so-called emergency area code) corresponding to the telephone number of the police headquarters that supervises the police station having jurisdiction over the installation location of each base station 3.

  For example, it is assumed that “110” is transmitted from the terminal 1 as an emergency call. In this case, the terminal 1 transmits the telephone number “110” to the base station 3. The base station 3 receives the telephone number “110” from the terminal 1 and recognizes that it is an emergency call, and transmits the telephone number “110” and the set and stored area code to the wireless communication network 5. (The base station 3 may transmit the area code together only in the case of an emergency call in this way).

  The exchange 6 stores an area code and a contact telephone number in association with each other. Therefore, the exchange 6 recognizes that it is an emergency call by receiving "110" from the base station 3, and if there is an area code received from the base station 3, confirms the area code. Thus, control is performed to connect the call “110” to the telephone number of the contact associated with the area code (for example, the police headquarters having jurisdiction over the area where the base station 3 is located).

  As an example, when the exchange 6 confirms that the area code is “A”, the exchange 6 controls the exchange network 60 to connect the call to the telephone number of the police headquarters corresponding to the area code “10”. As a result, the exchange 6 in the exchange network 60 cooperates to connect the call to the gateway exchange 7. The gateway exchange 7 connects to the fixed network side exchange 11 in the fixed communication network 8 in response to a connection request from the exchange 6. The fixed network side exchange 11 cooperates to connect a call from the gateway exchange 7 to the fixed telephone 9 of the police headquarters, and causes the fixed telephone 9 to receive the call. After that, when the fixed telephone 9 responds to the connection from the fixed network side exchange 11, a call can be made between the terminal 1 and the fixed telephone 9, and the user of the terminal 1 makes an emergency in the police headquarters in charge of his / her neighborhood. Can be notified.

  As described above, when the base station 3 stores the area code, the exchange 6 sets and stores the area code and the telephone number to be contacted, so that even if the terminal 1 moves, the base station 3 If the area code can be received from the station 3, the telephone number of the police station or the like having jurisdiction over the destination of the terminal 1 can be acquired from the area code. Emergency calls are never connected.

  However, when the base station 3 with which the terminal 1 is communicating does not store the area code, the exchange 6 cannot obtain the area code from the base station 3 and therefore cannot determine to which contact the call should be connected.

  In this case, in the present embodiment, an alarm indicating that the area code is not set in the base station 3 is transmitted to the monitoring device 12. Thereby, since the supervisor of the monitoring device 12 knows that the area code is not set in the base station 3 by the transmitted alarm, it can take the action of setting the area code for the base station 3. Therefore, it is possible to prevent a situation in which an emergency call cannot be made to a police station or the like in a call from the terminal 1 located in the base station 3.

  Specifically, similarly to the above-described example, when the terminal 1 calls “110”, it is assumed that the area code is not stored in the base station 3 that has received the call. At this time, the base station 3 receives the number “110” from the terminal 1 and recognizes that it is an emergency call and sends the number “110” to the exchange 6, but since the area code is not stored, the area code Will not send.

  The exchange 6 recognizes that it is an emergency call by receiving “110” from the base station 3 and also sends an alarm to the monitoring device 12 that the call connection destination is unknown because the area code is not transmitted. Send. The monitoring device 12 receives an alarm from the exchange 6 and selects a connection destination of the emergency call (or the monitoring device 12 may receive and respond to the call) and receives the call. Since it can be seen that the area code is not set and stored in the base station 3, the base station 3 is adapted to set the area code.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
