DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intelligent network system in a public telephone network, and more particularly, to a method and an apparatus for switching and connecting service switching points.

[0002]

2. Description of the Related Art Conventionally, a subscriber accommodated in a local exchange which does not have a function of transferring a calling subscriber number to a higher station cannot receive a special number service which requires the transfer of the calling subscriber number. Had been configured.

Japanese Patent Application Laid-Open No. 03-164971 discloses a system in which a calling subscriber number is searched from a database of a system center, and the calling subscriber number is added so that the special number service can be received.

[0004]

In the above-mentioned conventional subscriber number adding method, the calling subscriber number is retrieved from the database of the system center and transferred. The disadvantage is that the service can only be used from a specific terminal that can approach the database.

It is an object of the present invention to provide a service switching point in which a service requiring transfer of a calling subscriber number can be received from any subscriber accommodated in a local exchange which does not have a calling subscriber number transfer function. It is to provide a switching connection method and apparatus.

[0006]

[0007]

According to the present invention, there is provided a method for switching connection of a service switching point, comprising the steps of: for each special number service request call, detecting whether a calling subscriber number is received; Detecting that the originating subscriber number is dialed, notifying the originating subscriber of the personal identification number, notifying the originating subscriber of the call once, and storing the originating subscriber. Calling the subscriber number, dialing the notified personal identification number to the calling subscriber, checking the correctness of the dialed personal identification number, And transferring required data including the calling subscriber number.

The service switching point switching device of the present invention is a service switching point switching apparatus for transferring required data including a calling subscriber number to a corresponding special number service center in response to a subscriber's special number service request call in the intelligent network system. A means for detecting whether or not the calling subscriber number of the outgoing call has been received; a means for requesting dialing of the calling subscriber number when detecting that the calling subscriber number has not been received; Means for selecting, means for notifying the calling subscriber of the selected password, means for notifying the calling subscriber of the call being temporarily interrupted, and means for notifying the calling subscriber by the stored subscriber number. Means for calling the calling subscriber to dial the notified security code, and determining whether the dialed security code is correct or not. Means for matching comprises a subscriber number a match is confirmed when it is confirmed to the service center of the personal identification number, and a means for transferring the required data are stored.

[0009]

[Operation] The calling subscriber is dialed to store his / her own subscriber number, stored, and given a password, and then the calling subscriber is dialed with the stored number to dial the password, collated, and matched. Since the calling subscriber number is confirmed by the detection and the necessary data including the calling subscriber number is transferred to the corresponding special number service center, a special number service requiring the calling subscriber number can be received.

[0010]

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

FIG. 1 is a block diagram of an SSP to which a service switching point (hereinafter abbreviated as SSP) switching connection method of the present invention is applied, and FIG. 2 is accommodated in a subscriber exchange having no calling subscriber number transfer function. Outgoing subscriber 1
FIG. 4 is a diagram showing a sequence of a dialog signal between the SSP 30 and the SSP 30;

The SSP 30 receives and stores a call transmission requesting section 31 for instructing dialing of a calling subscriber number and a number dialed by the calling subscriber, in addition to a general service request call switching connection function. A digit receiving unit 32, a password for selecting a calling subscriber, and notifying the calling subscriber, and thereafter, a password notifying unit 33 for instructing on-hook, and calling the calling subscriber by the received calling subscriber number. It has an automatic dial section 34 and a password collation section 35 for dialing the notified personal identification number to the calling subscriber who has responded to the call and collating with the notified number.

Next, the operation of this embodiment will be described.

Assuming that a subscriber accommodated in the local exchange 21 having no function of transferring the calling subscriber number dials a number requesting a service requiring transfer of the calling subscriber number (step 41). , Subscriber exchange 2
1 connects the call to SSP30. The SSP 30 accumulates the service special number, detects the presence or absence of the calling subscriber number, and when it determines that there is no calling subscriber number, requests the calling subscriber to dial the own subscriber number via the calling number transmission request unit 31. (Step 42). In response to this request, the calling subscriber 10 dials his / her own subscriber number (step 43).
The SSP 30 receives and accumulates the data at the numeral receiving unit 32, notifies the temporary password to the calling subscriber from the password notifying unit 33, and then causes the calling subscriber to go on-hook (step 44). Thereby, the calling subscriber 10 goes on-hook (step 4).
5). Then, the outgoing subscriber number stored in the SSP 30 is dialed by the automatic dial unit 34 and called (step 46), and after waiting for a response (step 47), the temporary password previously notified is dialed (step 46). 48). When the calling subscriber 10 dials the personal identification number (step 49), the SSP 30 checks the received personal identification number with the number notified by the personal identification matching part 35 and confirms a match. The required data is transferred to the corresponding special service center (step 50).

[0015]

As described above, according to the present invention, the calling subscriber number is added to the SSP after confirming the calling subscriber number and the call is transferred to the corresponding special number service center. There is an effect that the subscriber accommodated in the subscriber exchange having no function can also receive the special number service requiring the transfer of the calling subscriber number.
