Description

  The present invention relates to a telephone, a telephone exchange, and a telephone communication system.

  For example, the following emergency call system is known as a contact system used for lifesaving when an emergency situation involving human life occurs due to an earthquake disaster, sudden illness, traffic accident or the like.

  The emergency call method is a system in which a disaster victim having urgency sends a call to a relay center called a location information center. Specifically, the position information center that has received the call signal first acquires the caller's position information by GPS. After that, the location information center selects a plurality of notification destinations close to the location of the caller among public facilities such as police stations, fire stations, and emergency medical institutions by referring to the map information database, and performs transmission processing in the order of selection. Have.

  If all of these facilities do not respond, call again in order. When the emergency notification destination responds, the location information of the emergency caller is transmitted to the responding emergency notification destination. Furthermore, when the emergency notification destination completes the talk process with the location information center, the location information of the emergency caller, the emergency notification destination name, and the telephone number are transferred to a third party emergency notification destination different from the emergency notification destination. In this case, the location information center is an organization that makes a telephone call to a public facility selected via a subscriber exchange or a relay exchange after reception.

  The following telephone contact devices are known as devices that target an area smaller than the target area of such an emergency call method. The telephone contact device is a device that prevents a sick person from being in the absence of nursing in an emergency. A telephone for a sick person in a sick room through an indoor telephone line, a general telephone in another place connected to the telephone, and an indoor telephone line Line adapters for switching between telephones and external telephones.

  The general telephone has a built-in memory device for storing a plurality of destination telephone number data with priorities, and a control unit for automatically switching connection of an external line call. When the call button on the sick telephone is pressed, the line adapter first connects to an indoor general telephone to enable extension calls, and if there is no response, the line adapter includes an external line registered in the memory device in advance. Call a plurality of destination telephone numbers for a predetermined time in the order of priority. Then, the telephone numbers are sequentially switched until there is a response from one of the other parties, and when there is a response from the other party, control is performed so that the other party's telephone is connected to the sick telephone and can talk.

  Further, the following method is known as an urgent contact method in an apartment house such as a condominium which is a limited small scale. In other words, in response to an emergency call from the alarm monitoring panel installed in the control room, a communication path is forcibly formed between the loudspeaker calling function and the alarm monitoring panel of the housing information panel main unit and the sub-main unit in each dwelling unit. A method for enabling a response operation is known. Thereby, it becomes possible for a resident to contact promptly between an alarm monitoring board and a resident, without taking a handset. Although this technology is an emergency contact system, it is possible depending on the configuration in the housing complex and cannot be applied to a contact means via a public telephone network.

Have. In the following description, the cellular phones 1a to 1k will be described as a representative.

  As illustrated in FIG. 1, each of the radio base stations 10 a, 10 b, and 10 c includes an antenna 11 that communicates wirelessly with the mobile phones 1 a to 1 k, a transceiver 12, and the like, and further communicates with the exchange 20. The transmitter / receiver 13 is provided. The radio base stations 10a to 10c and the exchange 20 are connected to each other via transmission lines 21 and 22 that use optical fibers, metal wires, or wireless.

  As illustrated in FIG. 3, the exchange 20 has a bus 23 connected to the CPU 22. The bus 23 is connected to a switch circuit 24, an input / output interface 25, MMs (main memories) 26a and 26b, DKs (disk devices) 27a and 27b, and the like. These MM and DK often have a redundant configuration (having two devices to configure an active system / standby system) as a countermeasure against failure. In FIG. 3, MM and DK are configured with two each because of the redundant configuration. However, in this embodiment, redundancy of MM / DK is not an essential configuration, and either one or both of MM / DK are not included. However, only one configuration may be used. The input / output interface 25 is connected to a plurality of line accommodating units 25a, 25b, 25c and the like. The line accommodating units 25a, 25b, and 25c are connected to the radio base stations 10a, 10b, and 10c, the fixed telephone network 31, and the like via the transmission circuits 21, 22, and 23.

As shown in the block of FIG. 4, the exchange 20 includes a dial receiving unit 28a, a processing unit 28b, an incoming call response processing unit 28c, a dial transmitting unit 28d, a talk unit 28e, and the like. The dial receiving unit 28a has a structure for receiving signals input from the cellular phones 1a to 1k via the radio base stations 10a to 10c. The processing unit 28b includes an analysis processing unit 28b _{1 for} the received number, a telephone number decomposition processing unit 28b ₂ based on the analysis processing, and an incoming call type processing unit 28b _{3 for} processing the type of incoming call. have. As the incoming call type, either a sequential call process or a simultaneous call process is selected as will be described later. Various processes in the processing unit 28b and the like are performed by the CPU 22 that executes a program.

  In the telephone communication system as described above, when the caller inputs the number by operating the key group 6a of one mobile phone 1a according to the flow shown in FIGS. Radio waves are transmitted to one or more telephones 1b to 1k on the receiving side via 10c.

  First, as shown in FIG. 5A, the caller inputs a number by operating the key of the mobile phone 1a which is a transmission terminal. As a result, as shown in FIGS. 5B and 5C, the receiving unit 9a in the mobile phone 1a receives the number and receives the service telephone number such as “116”, “106”, or a normal subscriber telephone. It is determined whether the number is an emergency call telephone number such as “110” or “119”, or a specific number for personal emergency transmission as described above. In the following description, for example, “999” and “990” are employed as the emergency call specific numbers.

  When receiving a number other than the specific number for emergency call, the receiving unit 9a transmits the number to the number transmitting unit 9e. As a result, as shown in FIG. 5D, the number transmission unit 9e in the mobile phone 1a communicates with the external radio base stations 10a to 10c by radio, and thereafter, the radio base stations 10a to 10c communicate with the exchange 20. connect.

  The exchange 20 that has received a number other than the emergency call specific number performs a normal telephone connection operation. For example, as shown in FIG. 4, the exchange 20 sends a signal from the dial transmitting unit 28d therein to the dial receiving unit 9f of one mobile phone 1h having the telephone number on the receiving side, and the calling unit 7b of the mobile phone 1h. And a series of line connection processing and response processing are performed. After the response is completed, the exchange 20 disconnects the line connection between the mobile phone 1a, 1h on the caller side and the callee side, as shown in FIG. If the number is not a specific number for emergency call, nor is it a normally used number such as a subscriber phone number, service phone number, emergency call phone number, etc. In addition, the exchange 20 ends the process without performing the line connection operation.

  On the other hand, when the receiving unit 9a receives the emergency calling specific number “999” or “990” in the transmitting-side mobile phone 1a, the receiving unit 9a transmits the specific number to the processing unit 9b. Thereby, the processing unit 9b performs the following processing.

  First, the processing unit 9b that has input the emergency call specific number first extracts a telephone number as shown in FIG. As a method for extracting the telephone number, for example, telephones of a plurality of emergency contacts A, B, and C from the emergency contact data group registered in the telephone directory data section 9c in the calling side mobile phone 1a shown in FIG. The number is automatically extracted, or depending on the situation, the telephone number selected and edited by the caller by key operation is extracted on the spot when an emergency occurs. As a telephone number automatically extracted from the emergency contact data group, for example, a number edited in advance before the occurrence of an emergency or a number of outgoing calls from the number data group stored in the outgoing history storage unit 9d is large. There is a specific number of numbers that are determined in order.

  As shown in FIG. 5G, the processing unit 9b that has extracted the telephone number performs a telephone number concatenation process for concatenating a plurality of telephone numbers into one electronic message. In the telephone number concatenation process, a special symbol indicating a delimiter, for example, “*” may be automatically inserted between a plurality of emergency contact telephone numbers. For example, as shown in FIG. 1, the destination names of mobile phones 1h, 1i, and 1j to which the extracted telephone numbers are assigned are A, B, and C, the telephone number of A is “09011111111”, and the telephone number of B is Assuming that “09022222222” and C's telephone number are “090333333333”, one message obtained by the concatenation process is, for example, “09011111111 * 090222222222 * 090333333333”. Furthermore, a special symbol indicating that the telephone call is an emergency call, such as “#”, may be inserted between the telephone number and the special symbol * in the mobile phones 1b to 1k on the receiving side. As a result, the receiving side telephones 1h, 1i, 1j display, for example, a special symbol “#” for emergency calls sent from the exchange 20 to display a symbol indicating emergency, for example “SOS”, on the display 7a. Let

  The plurality of telephone numbers connected in this way are further given a specific number for emergency call to the upper digit by the processing unit 9b, and edited by the processing unit 9b as a transmission message as shown in FIG. . The specific number for emergency call may be a predetermined number “999” or “990” on the caller side, or may be a number or a symbol newly created by the processing unit 9b of the telephone 1a based on the number. Moreover, you may edit by giving a caller's telephone number to the message | telegram to send.

  Such a message will be “999 * 09011111111 * 090222222222 * 090333333333” or “990 * 09011111111 * 090222222222 * 09033333333” using the above example. If the caller's phone number is “08011111111”, the first phone number next to the specific number is defined as the caller's phone number, and the outgoing message is “999 * 08011111111 * 09011111111 * 090222222222 * 090333333333” or “990” * 08011111111 * 09011111111 * 090222222222 * 09033333333 ". Further, when the special symbol “#” for emergency call is connected, the message becomes “999 * 08011111111 * # 09011111111 * # 090222222222 * # 09033333333” or “990 * 08011111111 * # 09011111111 * # 090222222222 * # 09033333333”.

  By the way, since the radio base stations 10a to 10c generally include the telephone number on the caller side in the data exchanged with the mobile phones 1a to 1k at the time of radio communication, the radio base stations 10a to 10c send an emergency call message. It is not mandatory to include the phone number of the party. Also, a numerical value of several digits from the top among telephone numbers generally used in a subscriber system or the like is a numbering system assigned to select and connect a region or a mobile terminal. For example, 03, 06 and 052 are area numbers given to the fixed telephone 32 indicating Tokyo, Osaka and Nagoya, and 080, 090 and the like are numbers given to the wireless terminals. A program and data for discriminating a telephone number of such a number system on the mobile phone side and the exchange side are stored, and the exchange 20 identifies that the number following the first three-digit emergency call specific number is a telephone number. If possible, a special symbol such as “*” does not have to be inserted in the telephone number separator. Therefore, when a plurality of telephone numbers are connected in the mobile phone 1a on the caller side, a special symbol such as “*” may not be inserted between the specific number and the telephone number.

  The edited message for emergency call is output from the processing unit 9b to the number transmitting unit 9e in the mobile phone 1a, and further, as shown in FIG. 5, the external transmitting base stations 10a to 10c from the number transmitting unit 9e. Is transmitted wirelessly.

  The radio base station 10a in the area in charge of the originating mobile phone 1a exchanges various data related to the mobile phone 1a by communicating with the exchange 20, and establishes communication with the mobile phone 1a. Further, as shown in FIG. 5, the radio base station 10 a transmits a telegram including the emergency call specific number received from the mobile phone 1 a and other data to the exchange 20.

  As shown in FIG. 6, when the first three digits of the number received by the dial receiving unit 28a in the exchange 20 is a specific number for emergency call, for example, “999” or “990”, the processing unit 28b Starts the next process based on the specific number from the dial receiver 28a. In the following description, when the specific number for emergency call is “999”, the simultaneous call process is described, and when “990”, the call process is sequentially described.

  First, the processing unit 28b of the exchange 20 analyzes a special symbol or number system of the emergency specific number and the consecutive numbers following it from the received outgoing message as shown in FIG. The symbol “*” is deleted and it is decomposed into a plurality of telephone numbers. Further, as shown in FIG. 6A, based on the type of the specific number, that is, “999” or “990”, the sequential calling method or the simultaneous calling method is selected, and the selected method is instructed to the dial transmission unit 28c. To do. By the way, the exchange 20 may select the general calling method without being restricted by the received specific number. For example, in the state where the number of lines to be connected in the exchange 20 is larger than the set number, congestion is likely to occur if the general call method is selected. In such a case, the process of changing the general call method to the sequential call method is performed. May be performed by the processing unit 28b.

  The dial transmitting unit 28c finally calls the mobile phones 1h, 1i, 1j of the destination names A, B, and C via the radio base stations 10b and 10c in accordance with the instructed calling method. As shown in FIG. 6A, the two calling methods are determined by the first three digits of the message, that is, “999” and “990”, and the exchange 20 performs the following simultaneous calling process, or Perform sequential call processing.

  The general call processing is performed when, for example, the first three digits of the outgoing message are “999”, and as shown in FIG. 6B, a plurality of telephone numbers on the called side included in the message, for example, “09011111111”, In this method, the cellular phones 1h, 1i, and 1j assigned “902222222” and “090333333333” are simultaneously called. At the same time as calling, for example, “SOS” is displayed on the display 7a of the incoming side mobile phones 1h, 1i, 1j based on the emergency call display special symbol “#” included in the message. Communication such as a call from the exchange 20 to the called mobile phones 1h, 1i, and 1j is performed via the radio base stations 10b and 10c.

  Then, as shown in FIG. 6B, it is determined whether there is a response to at least one mobile phone 1h (1i, 1j) in response to the call. When there are two responses, as shown in FIG.

  The talk process is a process for transmitting the automatic voice guidance stored in the talk unit 28e in the exchange 20 to the mobile phone 1i having the telephone number that has responded to the call after the second call. This is a process for transmitting a message such as “Since a situation occurred, a call was made, but another phone answered”.

  When at least one mobile phone 1h responds to the call, as shown in FIG. 6, the call to the mobile phone 1j that does not answer is stopped. Thereafter, as shown in FIG. 6, the state of the mobile phone 1 a on the calling side is determined.

  When the caller's mobile phone 1a is in the outgoing state, as shown in FIG. 6B, the incoming call side mobile phone 1h and the caller's mobile phone 1a are connected to the line, and a call is made. To start. In addition, as shown in FIG. 6B, when the caller side telephone 1a is disconnected, a call back process is performed as a call process on the caller side to connect the line. Further, as shown in FIG. 6A, when the telephone call ends and the telephone response is completed, the line is disconnected. If there is no telephone that responds to the simultaneous call, the line connection is terminated when the set time and the number of recall settings have elapsed, as shown in FIG. In this case, an automatic voice guidance stored in the talk unit 28e in the exchange 20, for example, “Please do not make a call and please call again” is sent to the mobile phone 1a on the caller side. May be communicated.

  As shown in FIG. 6A, when the first three-digit special symbol “990” is received in the message received by the exchange 20, the exchange 20 adopts the sequential calling method, and within the exchange 20, FIG. Processing as shown is performed. As shown in FIG. 7D, the sequential call processing is performed by sequentially calling the telephones 1h, 1i, and 1j having a plurality of telephone numbers included in the message, for example, “09011111111”, “090222222222”, and “090333333333” at a certain timing. Call repeatedly. Then, after a response is first received by one mobile phone 1h on the receiving side, the calling method ends the calling of the other mobile phones 1i and 1k on the receiving side. When calling, an emergency call is displayed on the display 7a of the mobile phone 1i, 1j, 1k on the receiving side.

  Then, as shown in FIGS. 7A and 7B, when one of the plurality of called cellular phones 1h, 1i, 1j has a response, the receiving-side cellular phone 1h that first responds And the line of the mobile phone 1a on the calling side are connected to start a call. Further, as shown in FIG. 7, the call to the remaining mobile phones 1i and 1j is terminated.

  Thereafter, as shown in FIG. 6A to FIG. 6, the state of the responding mobile phone 1a is determined, and thereafter, telephone line connection processing, call back processing, and the like are performed in the same manner as described above. If there is no telephone answering the simultaneous call, the line connection is terminated when a series of calls are made a set number of times as shown in FIG. In this case, an automatic voice guidance stored in the talk unit 28e in the exchange 20, for example, “Please do not make a call and please call again” is sent to the mobile phone 1a on the caller side. May be communicated.

  In both cases of simultaneous call processing and sequential call processing, the mobile phones 1h, 1i, and 1j on the receiving side that are called by the exchange 20 via the radio base stations 190b and 10c receive an emergency call included in the telegram. A special symbol indicating the presence and the telephone number of the calling party are transmitted and displayed.

  In the mobile phone 1i on the receiving side that has received the signal from the exchange 20 via the radio base stations 10b and 10c, the transmitted telegram is analyzed as shown in FIG. Determine if there is. If there is a special symbol for displaying an emergency call, an emergency call display process is performed on the display 7a. In the emergency call display process, as shown in FIG. 8F, the telephone number “08011111111” of the caller and the emergency call symbol, for example, “SOS” are displayed on the display 7a of the mobile phone 1h. Further, when there is no special symbol in the message, no emergency display is performed as indicated by No in FIG. When the incoming side mobile phones 1h, 1i, 1j have a display function, the phone number is displayed according to a normal operation.

  In addition, as shown in FIG. 8C, the processing unit 9g of the incoming-side mobile phone 1h causes the calling unit 7b to perform a ringing operation regardless of the presence or absence of a special symbol for displaying an emergency call. In the cellular phone 1h that has responded to the call, as shown in FIGS. 8D, 8A, 8A, 8A, 8A, 8A, 8C, the telephone conversation is started, the response is terminated, and the line is disconnected. If there is no response, the call is terminated as indicated by No in FIG.

  When the incoming side mobile phone 1h responds by the ringing operation as described above, as described above, the exchange 20 connects the outgoing side mobile phone 1a and the incoming side mobile phone 1h to make a call possible state. . Further, when the calling-side mobile phone 1a is disconnected before the connection, as described above, the calling process is performed by calling back to the calling-side mobile phone 1a and connecting to the receiving-side mobile phone 1h. Do.

  When a call between the incoming-side mobile phone 1h and the outgoing-side mobile phone 1a is started, the exchange 20 determines that the call is in a normal telephone line connection state, and a specific number connected by an emergency special symbol. Delete the phone number data that did not respond.

  According to the telephone contact system as described above, a plurality of emergency contact numbers can be connected and further connected by simply dialing a specific number defining emergency contact in the mobile phone 1a which is a terminal on the caller side. The telephone number is connected to the specific number and transmitted to the exchange 20. Further, since the exchange 20 receives a specific number for emergency contact, it unlinks a plurality of connected telephone numbers and performs an incoming call operation for each telephone number of an emergency contact. Therefore, it is not necessary to redo, or the number of redemptions can be reduced.

  As a result, the resource release / supplement processing of the system of the exchange 20 by re-calling can be omitted, that is, resources can be diverted, so that the risk of promoting congestion can be reduced.
