Abstract

<P>PROBLEM TO BE SOLVED: To provide an IP telephone system enabling using an emergency contact line, such as dial 110 (police) or dial 119 (fire department). <P>SOLUTION: When judging that a telephone number is dialed (Y in S1), a CPU 23 decides whether the input telephone number matches a telephone number stored in a RAM 24 (S2). Then, if the telephone number matches (Y in S2), the CPU 23 performs control so that a call is made from a cellular phone device 12 at the input telephone number via a communication I/F 21 and ends processing; whereas if it is decided that the input telephone number does not match the registered telephone number stored in the RAM 24 (N in S2), the CPU 23 performs control so that a call is made at the input telephone number via an IP network 4 of the Internet, and ends the processing. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an IP telephone apparatus that provides a telephone service using the Internet, and particularly relates to connection to an emergency line such as 110 or 119.

In recent years, IP (Internet Protocol) telephone devices using the Internet have become widespread. However, when an emergency communication line such as No. 110 or No. 119 is used in an IP telephone device, there is a possibility that a connection failure may occur. For this reason, the proposal for connecting with an emergency line is made.
For example, Patent Document 1 discloses an IP telephone apparatus that enables reconnection even when the communication line is disconnected when the communication line is an emergency line such as 110 or 119.
Japanese Patent No. 3139623

As described above, in the conventional IP telephone apparatus, when an emergency contact line such as No. 110 or No. 119 is used, there is a risk that a connection failure may occur.
Therefore, an object of the present invention is to provide an IP telephone apparatus that can use emergency contact lines such as 110 and 119.

In order to achieve the above object, an invention according to claim 1 is an IP telephone apparatus that performs communication by packetizing voice data and performs mutual communication with a communication terminal that performs communication with a base station using wireless communication. The communication interface is provided, and when the destination is an emergency contact number, a line is connected to the emergency contact number using the communication terminal.
According to a second aspect of the present invention, in the IP telephone apparatus according to the first aspect, a storage means for storing a telephone number and a determination for determining whether or not the input telephone number input is a telephone number stored in the storage means. Means and a control means, and the control means, when the input telephone number matches the telephone number stored in the storage means, from the communication terminal to the telephone number via the communication interface And control to make a call to the telephone number via the Internet if the input telephone number does not match the telephone number stored in the storage means. It is characterized by.

  The IP telephone apparatus of the present invention is provided with a communication interface for mutual communication with a communication terminal that can communicate with a base station using wireless communication. By connecting a line to a contact, an emergency contact line can be surely secured.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a diagram showing the configuration of the entire IP telephone system according to the present embodiment.
In the IP telephone apparatus 1 shown in FIG. 1, when a caller picks up the handset and dials the destination telephone number, the content of the call is transmitted to the IP telephone adapter apparatus 2 as analog voice. The IP telephone adapter 2 converts the analog voice signal taken from the IP telephone apparatus 1 into a digital signal (voice coding) and converts it into an IP packet. The voice packet converted from the analog signal by the IP telephone adapter 2 is transmitted via the router via the IP telephone provider 3 and the IP network 4 via an ADSL line or the like.
Here, when the destination of the IP telephone device 1 is the IP phone 6, the voice packet is converted into analog voice by the destination IP phone adapter device 5 and connected to the destination IP phone 6.
Further, when the other party is a general subscriber telephone, the voice packet is converted into analog voice by the gateway 7 from the IP network 4 and connected to the other party general subscriber telephone 9 via the telephone network 8. become.
In the IP telephone apparatus 1 used in the IP telephone service adopting such a telephone communication system, the IP network 4 is usually used even when the destination of the IP telephone apparatus 1 is an emergency line such as 110 or 119, for example. From the top, you will be connected to the nearest emergency contact 11 via the IP adapter or gateway 10, but in the case of an IP phone, other normal calls will be made even if it is an emergency line such as 110 or 119 Since the process is performed with the same connection quality as the caller, even if the line is disconnected for some reason such as overload after the emergency line is connected, the caller can be identified but cannot be reconnected. It was.
Therefore, in the IP telephone device 1 according to the present embodiment, when the destination is an emergency contact line such as 110 or 119, a line is established with the nearest emergency contact using the mobile phone device 12. To connect. The mobile phone device 12 is a communication terminal that can communicate with a base station using wireless communication.

FIG. 2 is a diagram showing an internal configuration of the IP telephone apparatus according to the present embodiment.
As shown in FIG. 2, the IP telephone apparatus 1 according to the present embodiment includes a communication interface (I / F) 21, a telephone I / F 22, a CPU 23, a RAM 24, and a communication means 25 connected to a bus line 26, respectively. Yes.
The communication I / F 21 is an interface for performing mutual communication with the mobile phone device 12. The telephone I / F 22 is an interface for connecting to a telephone (not shown). The CPU 23 controls the IP telephone device 1 of the present embodiment. In the RAM 24, emergency contact numbers such as 110 and 119 are stored in advance as registered telephone numbers. The communication means 25 is an interface for connecting to a line or a LAN.
In the IP telephone apparatus 1 according to the present embodiment, the CPU 23 determines whether or not the number dialed by the caller by picking up the handset is an emergency contact number. Makes a call from the mobile phone device 12 connected via the communication I / F 21 to the nearest emergency contact 11. In this way, when calling from the IP telephone apparatus 1 to the emergency contact number, the mobile telephone apparatus 12 can connect the line, so that the IP telephone apparatus 1 can use the emergency contact line. .

FIG. 3 is a flowchart showing processing executed by the IP telephone apparatus according to the present embodiment.
The processing operation shown in FIG. 3 is realized by the CPU 23 shown in FIG. 2 executing a program stored in a ROM, RAM 24, etc. (not shown).
In this case, if the CPU 23 determines that the telephone number has been dialed (Y in S1), it determines whether or not the input telephone number matches the registered telephone number stored in the RAM 24 (S2). If they match (Y in S2), control is made to make a call to the telephone number input from the mobile phone device 12 via the communication I / F 21, and the process ends.
On the other hand, if it is determined that the input telephone number does not match the registered telephone number stored in the RAM 24 (N in S2), control is performed so as to make a call to the input telephone number via the IP network 4 which is the Internet. To finish the process.
In the present embodiment, telephone lines such as 110 and 119 are used as emergency lines. However, this is merely an example, and other telephone lines can of course be registered as emergency lines.

It is the figure which showed the structure of the whole IP telephone apparatus which concerns on embodiment of this invention. It is the figure which showed the internal structure of the IP telephone apparatus of this Embodiment. It is the flowchart which showed the process which the IP telephone apparatus of this Embodiment performs.
