Description

  The present invention relates to an IP fixed telephone that performs voice communication by mutually converting voice signals and IP packet data, and transmitting and receiving the IP packet data between communication terminals connected to an IP network by a fixed line, The present invention also relates to an IP landline telephone system and an IP landline telephone method for notifying location information of a sender in an emergency.

  In recent years, so-called IP telephones via IP networks are becoming popular due to the increase in capacity and speed of communication networks. This IP phone is assigned an IP fixed phone number “050”, and this number enables a call by sending and receiving IP packets through the IP network.

  By the way, conventionally, in a communication business, an IP fixed telephone that does not have a so-called public line telephone number “0AB to J” cannot be used for an emergency call or the like because a caller cannot be specified. However, the usage rate of IP landline telephones has been increasing year by year, and it has become a situation that cannot be neglected as a related organization in the country, and measures to improve these situations are being studied.

As a technique for specifying the location of the caller in the IP fixed telephone, there is one disclosed in Patent Document 1. In the technology disclosed in Patent Document 1, a location information database server that links a telephone number, address information, and location information is installed on the IP network side, and when an emergency call destination is called by an IP fixed phone, this IP The telephone number of the fixed telephone is recognized by the exchange server of the switching center, and the recognized telephone number is transferred to the subscriber information database server. The subscriber information database server transfers the recognized telephone number to the location information database server, and the location information database server searches the address information and location information by the phone number, and the searched address information and location information are exchange server. Forward to. The exchange server transmits the address information and the location information to the emergency call destination.

In this case, since the communication terminal itself measures position information by GPS, the location of the communication terminal is notified to the destination without depending on the telephone number of the public line to which the communication terminal is connected. can do.

  Further, in the above invention, the location information acquisition unit acquires a terminal identifier of the communication terminal on the transmission side, identifies a communication terminal on the transmission side based on the acquired terminal identifier, and the transmission side The location information may be acquired by searching a location information database provided on the IP network side that stores the location information of the communication terminal in association with each other. In this case, for example, a terminal identifier (MAC address, IP address, etc.) of a communication terminal and the position information (latitude / longitude) of the communication terminal are associated and registered in the position information database installed on the IP network side. By doing so, the location of the communication terminal can be notified to the callee only by the mechanism on the IP network side.

  In the above invention, the terminal identifier includes a line identifier that identifies a fixed line to which the communication terminal on the transmission side is connected, and the position information is the latitude and longitude of the home side connection terminal of the fixed line. preferable. In this case, since the position of the home side connection terminal of the fixed line, not the communication terminal itself, is identified by the line identifier, the fixed position information can be acquired regardless of the connected communication terminal.

  In the above invention, the notification selection unit sets whether or not to notify the location information based on a user operation, and the emergency notification unit acquires the destination telephone number from the communication terminal on the transmission side, and responds to the acquired telephone number. Thus, a function for invalidating the setting in the notification selection unit can be added. In this case, the addition of the position information to the IP packet data is executed according to whether or not the position information specified by the notification selection unit and the emergency notification unit can be notified. In this case, you can select whether to notify or not notify the location information based on the user's will when sending in normal times, which can protect personal information. The location information can be notified to the call destination without waiting for the user's selection operation.

  As described above, according to the present invention, in the case of an emergency call in an IP phone and various service businesses that can be performed based on the data, the location information of the IP fixed phone, etc. without depending on the public telephone line number Can be notified to the other party.

  As a result, according to the present invention, as a service unique to IP telephones, it is possible to improve the product value of IP telephones and to add location data with high information accuracy at the time of emergency calls, or to simplify, automate, and build a database system during telephone commercial transactions. Simplification can be achieved, and furthermore, a wide variety of services such as call assistance in an aging population can be provided.

In the second embodiment described above, a terminal identifier such as an IP telephone number, a MAC address, or an IP address assigned to the telephone terminal is used for identifying the telephone terminal on the calling side. The location information on the calling side is acquired by a line identifier that identifies a fixed line to which the telephone terminal is connected.

  FIG. 7 is an explanatory diagram showing a schematic configuration of the IP telephone system according to the present embodiment. In the present embodiment, the same components as those in the second embodiment described above are denoted by the same reference numerals, and the functions and the like thereof are the same unless otherwise specified, and the description thereof is omitted.

  In the present embodiment, the terminal identifier that identifies the telephone terminal 1a includes a line identifier that identifies the fixed line 10 to which the originating telephone terminal 1a is connected, and the location information is the home side of the fixed line 10 The latitude and longitude of the connection terminal.

  This line identifier is held by, for example, the line identification unit 41 arranged on the IP network 4 or the public line network. The line identification unit 41 makes a call in response to a request from the position information addition unit 53. A fixed line that has been detected is detected, a line identifier that identifies the fixed line is read out, and notified to the database search unit 51 of the call agent 5 together with other terminal identifiers (MAC address, IP address, etc.). The line identification unit 41 is provided in a device that can identify individual wiring from a user's house, such as a splitter or gateway device on a telephone office side, an exchange, a DSLAM (Digital Subscriber Line Access Multiplexer), or TDM (Time Division Multiplexing). be able to.

  Note that the notification of the line identifier by the line identification unit 41 may be transmitted, for example, added to the header portion of the IP packet related to the call transmitted / received on the line, or a separate control from the IP packet. It may be transmitted as a signal.

  The position information database 5a stores table data T2 that associates line identifiers and position information as shown in FIG. 8, and the database search unit 51 is based on the line identifiers acquired from the line identification unit 41. The table data T2 is collated, position information is acquired, and the acquired position information is output to the position information adding unit 53.

  By operating the IP telephone system having the above configuration, the IP telephone method of the present invention can be implemented. Note that the overall operation of the IP telephone system in this IP telephone method is the same as that of the first embodiment described above (see FIG. 3), but in this embodiment, location information acquisition and location information addition in steps S103 and S104 are performed. This process is performed based on the line identifier.

  More specifically, first, when the general user 1 is dialed in the dial unit 16, the telephone number of the call destination is input to the operation signal acquisition unit 17, and based on this, the calling process is started by the VoIP unit 12. At the same time (S101), the notification selection unit 18 confirms the notification information non-notification setting (S102). For example, when the notification selection unit 18 has a notification / non-notification setting stored in advance, it is referred to and a special number such as “184” or “186” is added to the beginning of the telephone number when making a call. If so, the judgment is made with reference to this special number.

  When it is determined in step S102 that the notification of the position information is permitted (“Y” in step S102), a notification signal indicating that the notification is permitted is sent from the notification selection unit 18 as shown in FIG. When transmitted to the adding unit 53 (S201 and S202), the position information adding unit 53 transmits a request signal to the line identifying unit 41, and the line identifying unit 41 identifies the line related to the call ( S301). The line identifier identified by the line identification unit 41 is notified to the database search unit 51 on the call agent 5 side (S302 and S303), the position information database 5a is searched (S304), and the search result is acquired as position information. This is input to the position information adding unit 53 and added to the header portion of the IP packet data (S306).

  As shown in FIG. 3, the IP packet data to which the location information is added is transmitted to the telephone terminal 3a of the emergency call destination 3 by the exchange processing by the call agent 5, and the location information analysis unit 33 on the side of the telephone terminal 3a Thus, position information is read from the IP packet data. When reading the position information, an address or the like is searched from the latitude and longitude, and the address or the like as a search result may be used as the position information. Then, the position information read by the position information analysis unit 33 is displayed by the position information display unit 35 (S105). Thereafter, the telephone call is started by IP telephone (S106).

  On the other hand, when it is determined in step S102 that the notification of the position information is rejected (“N” in step S102), the emergency notification unit 19 then determines whether or not the call destination is the emergency call destination 3. Judgment is made (S107). Specifically, based on the destination telephone number input from the operation signal acquisition unit 17, referring to the table data in which the telephone number (110, 119, 118, etc.) of the emergency call destination 3 is held, It is determined whether or not the call is made.

  If it is an emergency call destination (“Y” in step S107), the non-notification setting in the notification selection unit 18 is invalidated (S108), and the processes in steps S103 to S106 (FIG. 3) and S301 to S306 (FIG. 8) described above are performed. Execute. On the other hand, if the destination is not emergency call destination 3 (“N” in step S107), non-notification setting in notification selection unit 18 is enabled (S109), and location information addition processing in location information addition unit 13 is prohibited. The position information is not displayed (S110).

(Operations and effects according to this embodiment)
According to the IP telephone system and the IP telephone method according to the present embodiment described above, the telephone terminal 1a is identified based on the line identifier that identifies the fixed line 10, and the latitude of the home-side connection terminal of the fixed line 10 Since the position information is longitude and longitude, fixed position information can be acquired regardless of the connected telephone terminal.

[Example of change]
In the first embodiment and the second embodiment described above, the case where only location information is transmitted as data for emergency notification has been described as an example. For example, blood type, emergency contact information, chronic disease are conscious of future service expansion. A certain data area may be reserved as a reserved area so that data such as a disease history can be added.

  In the above embodiment, the position information is latitude / longitude, but information such as a zip code may be specified.
