  ADVANTAGE OF THE INVENTION According to this invention, the switching hub which enables a telephone call outside without providing telephone equipment in the place where carrying-in of a mobile communication apparatus is prohibited can be provided.

It is a block diagram of the switching hub concerning one embodiment of the present invention. It is a figure explaining operation | movement of the switching hub of FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a block diagram of a switching hub according to the present embodiment.

  As shown in FIG. 1, a switching hub (network switch, switch) 1 includes a routing table 2 that stores an IP (Internet Protocol) address and a port of a connected device in association with each other. The routing table 2 is stored in the main chip 3 inside the apparatus.

  Here, as an example, a case where three switching hubs 1 according to the present embodiment are connected as shown in FIG. 2 will be described. Hereinafter, the three switching hubs 1 are respectively referred to as switching hubs 1a to 1c, the IP address of the switching hub 1a is 192.168.8.5, the IP address of the switching hub 1b is 192.168.6.82, and the switching hub 1c Assume that the IP address is set to 192.168.6.87.

  In this example, the first port of the switching hub 1a and the first port of the switching hub 1b are connected, and the second port of the switching hub 1b and the thirteenth port of the switching hub 1c are connected.

  In this case, the routing table 2 of the switching hub 1a stores the IP address 192.168.8.5 and the first port, and 192.168.6.82 and the second port in association with each other. Further, the routing table 2 of the switching hub 1b includes 192.168.6.8. X (all IP addresses starting with 192.168.) And the first port are stored in association with each other. Similarly, the routing table 2 of the switching hub 1c has 192.168.6.8. X (all IP addresses starting with 192.168.) And the 13th port are stored in association with each other.

  As an example, when data is transmitted from the switching hub 1c to the IP address 192.168.6.812 (switching hub 1b), first, the switching hub 1c refers to its own routing table 2 and stores the data. Transmit from 13 ports. The switching hub 1a that has received the data at the second port refers to its own routing table 2 and transfers the received data to the first port for transmission. As a result, data is received by the switching hub 1b.

  Now, the switching hub 1 according to the present embodiment includes an address selection unit 4, a call control unit 5, a call speaker 6 and a microphone 7, and an analog / digital converter 8. That is, the switching hub 1 is obtained by adding a call function to a normal switching hub.

  The address selection means 4 is means for selecting the IP address of the call destination. Here, the push button type address selection means 4 in which the IP address of the call destination is set to each button is mounted on the casing of the switching hub 1, and the IP address of the call destination corresponding to the button pressed by the operator is selected. However, the specific configuration of the address selection unit 4 is not limited to this. For example, it has a numeric keypad similar to that of a normal telephone, a number / IP address correspondence table, and is configured so that the destination IP address is selected by referring to the correspondence table using the number entered with the numeric keypad. Also good.

  Note that in an IP telephone system that is generally used at home, etc., first communicate with a PBX (telephone exchange) to obtain a destination IP address, and then communicate with a device having the obtained IP address. However, in this embodiment, the IP address of the call destination is directly specified without using the PBX, and communication is performed with the device having the specified IP address. Therefore, a large-scale facility including PBX or the like is unnecessary, and the cost is low.

  The call control unit 5 refers to the routing table 2 to communicate with the device having the IP address selected by the address selection unit 4 and transmit / receive a digital audio signal to / from the device. The call control unit 5 is mounted on the main chip 3.

  The speaker 6 and the microphone 7 may be provided integrally with the switching hub 1 or may be provided separately via an interface such as an RJ (Registered Jack) 11 and a cable. Further, one of the speaker 6 and the microphone 7 may be provided integrally with the switching hub 1 and the other may be provided separately. The speaker 6 and the microphone 7 may be integrally formed to form a receiver or a headset.

  The analog / digital converter 8 converts the analog audio signal input from the microphone 7 into a digital audio signal and outputs the digital audio signal to the call control unit 5, and converts the digital audio signal from the call control unit 5 into an analog audio signal. Output to the speaker 6.

  When a call is made on the switching hub 1, first, a button in the address selection means 4 in which the IP address of the call destination is set is pressed. When the button is pressed, the call control unit 5 starts communication with the call destination device. The analog audio signal input from the microphone 7 is converted into a digital audio signal by the analog / digital converter 8 and transmitted to the call destination device via the call control unit 5. The digital audio signal input from the call destination is received by the call control unit 5, converted to an analog audio signal by the analog / digital converter 8, and output to the speaker 6. As a result, a call can be made with the device at the call destination.

  As described above, in the switching hub 1 according to this embodiment, communication is performed with the address selection unit 4 that selects the IP address of the call destination and the device with the IP address that is selected by the address selection unit 4 with reference to the routing table 2. The call control unit 5 that transmits and receives digital audio signals to and from the device, the speaker 6 and the microphone 7 for calls, and the analog audio signal input from the microphone 7 is converted into a digital audio signal to control the call. And an analog / digital converter 8 that converts the digital audio signal from the call control unit 5 into an analog audio signal and outputs the analog audio signal to the speaker 6.

  As a result, a switching hub 1 with a calling function can be realized. By using this switching hub 1, even if a mobile communication device such as a data center is prohibited from being brought in, telephone equipment is not provided. It becomes possible to talk to the outside.

  Since the switching hub 1 includes the routing table 2, the routing table 2 can be used to perform voice communication in the same way as normal data communication, and a voice call system can be constructed at low cost. Is possible.

  The present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the spirit of the present invention.

  For example, in the above-described embodiment, a case where a one-to-one call is performed has been described. However, a one-to-many communication can be configured. In this case, the switching hub 1 on the transmission side (master station) transmits a digital audio signal to the switching hub 1 (addressed to a plurality of IP addresses) on the plurality of reception sides (slave stations).

  Further, although not mentioned in the above embodiment, it may further comprise an incoming call notification means for notifying an incoming call and a reception notification means for notifying the outgoing call partner that the call partner has confirmed the incoming call as a pre-stage of the start of the call. . As the incoming call notification means, a device that sounds a ringtone when communication is received from the call control unit 5 on the other side can be considered. As a means for notifying the reception, there may be a means for transmitting an incoming call confirmation signal to the other party's device when the reception button is pressed at the time of incoming call (or when the handset is picked up). What is necessary is just to comprise the telephone call control part 5 so that it may start.
