Further, the terminal 10 having the ISDN interface dials the ISDN line number β to send the call to the center 30. In this way, the connection can be established by transmitting from the transmitting terminal of the same line type to the receiving terminal.

FIG. 6 is a diagram for explaining the second conventional method. The system shown in the figure is an example in which n analog lines are connected to the communication network 20 and the function of confirming the communicability of ISDN is used, and it is fixed by using the control of the communicability of the ISDN interface. The calling side can reach the desired line with one number up to the number of lines. In the figure, the primary-group ISDN interface has a channel configuration of 23B + D, and the total (n + m) of the line n that answers a call sent from an analog line and the line m that answers a call sent from an ISDN is up to 23. In that case, the incoming call is possible.

FIG. 9 is a diagram for explaining the third conventional method. This figure is an example of a PBX that accommodates a plurality of primary-group ISDN interfaces, performs exchange processing depending on the originating line type, and receives an incoming call at an extension line to which a communication terminal compatible with the originating line is connected.

[0007]

However, the above-mentioned first to third conventional methods have the following problems.

When the terminal has an ISDN communication means, the center side It is necessary to dial the ISDN number β to receive the call. Therefore, on the terminal side, it is necessary to uniquely set the number for accessing the center according to the terminal type, which requires operation by the terminal user, and the access number depends on the line to which the terminal is connected. There is a problem that the terminal supplier needs to make the pre-setting of the above. Especially, communication means by analog telephone line, IDSN
In the case of a mobile terminal provided with both communication means by line, there is a problem that the user's operation frequently occurs every time the line used is changed.

Next, in the system shown in FIG. 8, when the communication possibility confirmation mechanism in ISDN is used, control on the terminal side is required, and there is a limit to the number of lines that can perform representative incoming call control. That is, for example, the primary interface is
Since the channel configuration is 23B + D, the total number of lines that respond to calls sent from analog lines and lines that respond to calls sent from ISDN cannot exceed 23. For this reason, for example, on the traffic of the service 50
If a line is required, the communication possibility confirmation function for one line of the primary ISDN interface is not sufficient.

In addition, the system shown in FIG. 9 requires a subscriber to newly install a PBX when an incoming call is received at an extension to which a communication terminal compatible with the originating line is connected, which is expensive. And the system becomes complicated. The present invention has been made in view of the above points, and solves the above-mentioned problems of the related art. Only by registering one connection number to be registered in a communication terminal, the line type of the calling side (analog telephone network / ISD
According to N), it is an object of the present invention to provide an analog / ISDN cooperative communication system capable of network service connecting to a line of the same type as the calling side among a plurality of types of lines provided on the center side.

With reference to the correspondence table 440, a call setting signal is generated based on the acquired information. This call setup signal is transferred to the destination exchange 430 via the common line signaling network 420.

The destination exchange 430 connects to the corresponding terminal device based on the acquired call setting signal. here,
It is assumed that the contents of the correspondence table 440 are the same as the contents of the above-mentioned table 1. Therefore, the transfer signal generation unit 412 searches the correspondence table 440 based on the call request signal from the line identification unit 411 and the identification result, so that the connection destination is the ISD.
It is determined whether it is the terminal device I accommodated in N or the terminal device A accommodated in the analog telephone line, and if necessary based on the determination result, the connection destination of the call setting signal is changed, The call setting signal is transferred to the destination exchange 430.

A detailed description will be given with reference to Table 1 above.
