In this embodiment, the GW 103 grasps the telephone number of the calling terminal 101 by the caller number notification service of the public network 102, but notifies the GW 103 from the calling terminal 101 by a PB signal before the password. You may do it.

Further, the confirmation of the password may be omitted.

When the CPU 201B of the GW 104 receives the telephone number of the calling terminal 101 and the telephone number of the called terminal 106 via the data communication unit 209B of the leased line network interface 202B (S501), these telephone numbers are stored in the memory 204B. Stored in the SRAM,
The data is transferred from the RAM to the public network interface 203B. The CPU 201B includes a public network interface 203
A call setup including the telephone number of the called terminal 106 as the called address to the public network 105 via the connection line 114 of the public network 105 to notify the called terminal 106 of the called by the procedure communication unit 200 of B. Send a message.

At this time, the CPU 201B of the GW 104
The telephone number of the calling terminal 101 is written in the call setup message for the ISDN (S502). Calling terminal 10
The telephone number 1 may be written as the calling subaddress in the call setup message. This subaddress may be a destination subaddress instead of a source subaddress. The data other than the sub-address may be written into data that can be arbitrarily written by the GW 104, such as user / user information. The originating address is the address of the GW 104. The public network 105 notifies the called terminal 106 of the incoming call.

The calling signal notified from the public network 105 to the called terminal 106 includes the called terminal 106 as a called address.
Of the GW 104 is included as the originating address. Further, the calling signal includes the calling terminal 10
1 is included as a sub-address.

If the network has a service for notifying the called side of the information included in the calling signal from the calling side, the IS
A network other than the DN can be used.

At the time of receiving a call (S601), the CPU 301 of the called terminal 106 determines whether or not communication is being performed via a public network, a dedicated network, and a public network (S602). Here, when it is determined that communication is being performed on the public network, the private network, or the public network, the sub-address is referred to and the calling terminal 10 is referred to.
1 is displayed on the display unit 310. At this time, the fact that the incoming call is via the public network, dedicated network, or public network is also displayed (S603).

If it is determined that communication is being carried out only through the public network, the telephone number of the calling terminal is displayed on the display unit 310 with reference to the calling address. At this time, it is simultaneously displayed that the incoming call is only the public network (S604). Then, communication is started (S605).

The called terminal 106 stores the telephone number of the GW 104 in the memory 204 in advance, and if the telephone number of the GW 104 matches the calling address notified from the public network 105 at the time of receiving a call, the public terminal It is determined that the incoming call is a dedicated-public (public network-dedicated line network-public network) call.

FIG. 7 shows a display section 310 of the called terminal 106. It should be noted that GW103 and GW10 are not public-only-public connections.
If 4 is an Internet telephone connected via the Internet, a message to that effect is displayed.

When the terminal 106 originates a call using the address of the terminal 101 as a destination address, the call is received by the terminal 101 via the public networks 105 and 102 (not via the GWs 104 and 103).

When the terminal 106 originates a call using the address of the GW 104 as the destination address and the address of the terminal 101 as the destination subaddress, the GW 104 receives the address of the terminal 101 as the destination subaddress. In this case, G
W104 connects terminal 1 to public network 102 via GW103.
Call 01. Therefore, terminals 106 and 101
They are connected via public networks 105 and 102 and GWs 104 and 103.

As described above, in the embodiment of the present invention, the GW 103 is a first line connection device and the GW 104 is a second line connection device.
In a communication system connected to a public network 105 such as ISDN for notifying information included in a call signal from a caller to a callee, the GW 104 receives a call to the GW103 in response to a call to the GW103. A call signal including caller information for specifying the caller (calling terminal 101) is sent to the public network 105.

In response to the call signal, a call notification signal including the caller information is transmitted from the public network 105 to the call terminal 106.

Therefore, the receiving terminal 106 can specify the calling terminal 101.

The GW 104 sends a call signal including the above-mentioned sender information as a subaddress to the public network 105. Also, in the additional information area other than the sub-address of the call signal,
The caller information may be written.

When a call signal including the caller information as a subaddress is transmitted from the GW 104 to the public network 105, a call notification signal including the address of the GW 104 as a call address and the caller information as a subaddress is transmitted from the public network 105. The call is sent to the called terminal 106.

The GW 103 and the GW 104 are connected by a dedicated line network or the Internet. Therefore,
Connection fee between the calling terminal 101 and the GW 103;
03 and the connection fee between the GW 104 and the connection fee between the GW 104 and the called terminal 106, the sum of the three charges is the same for the calling terminal 101 and the called terminal 106 only for the public network without passing through the GW 103 and 104. If the connection fee is lower than the connection fee, the connection fee can be saved. However,
Communication quality may be degraded by voice compression processing between the GW 103 and the GW 104.

When the GW 103 detects an incoming call, the GW 103
04, a predetermined signal is sent out, and the predetermined signal
W104 sends out a call signal.

The calling terminal 101 makes a call to the dial number of the GW 103 and, while connected to the GW 103,
04 sends out information for specifying the other party to be called.

The GW 104 sends a call signal for calling the other party specified by the GW 103 to the public network 105.

However, the called terminal 106, the GW 103,
By contracting in advance with the service provider of the GW 104, when a call is received to the GW 103, the GW 104
However, the called terminal 106 may always be called. In this case, the receiving terminal 1 is transmitted from the GW 103 to the GW 104.
It is not necessary to send information specifying 06.

The GW 103 communicates with the first

It corresponds to a computer-readable storage medium on which a program for functioning as a sending unit for sending to the network 105 is recorded.

Further, the called terminal 106 is notified by the public network 105 as a caller's address information at the time of receiving a call.
The connection route to the communication partner is determined according to the address information of 104, and display is performed according to the determined connection route.

That is, the receiving terminal 106 determines the connection route with the communication partner in accordance with the address information of the GW 104 notified as the address information of the caller from the public network 105 at the time of receiving the call, and the CPU 301 which determines the connection route. And a display unit 310 that is a display unit that performs display according to the connected connection path.

The memory 304 of the called terminal 106
Public network 105 for notifying caller address information when receiving a call
Means for determining a connection path with a communication partner in accordance with the address information of the GW 104 notified as address information of the caller from the public network 105 at the time of receiving a call; This corresponds to a computer-readable storage medium storing a program for functioning as display control means for performing display control so as to perform display in accordance with the program.

Therefore, when the line quality is poor due to the connection path, it is possible to know that the cause of the poor line quality is the connection path.

In the above embodiment, the GW 103 is connected to the public network 1
