In FIG. 1, reference numeral 30 denotes a subscriber terminal 10 which is accommodated in its own exchange and which relays the call connection request to the exchange of the other station when requesting call connection to a subscriber terminal accommodated in an exchange (not shown) of another station, In response to a call connection request from the subscriber terminal accommodated in the exchange of the subscriber terminal 10 of its own station to the subscriber terminal 10 of its own station, a number translation is requested to the number translator 20 and a call connection process is executed And a call processing unit.

Next, a method of controlling the operation of the guide band of the pre-service electronic exchanger according to the present invention will be described in detail with reference to the flowcharts shown in FIGS. 2A and 2B.

First, the data memory 24 is registered with a password for entry into the usable state and entry into the idle state assigned to the corresponding guide 12, and the data memory 24 is provided with a password 12) can be registered to a password uniquely assigned to the operator.

The password is preliminarily registered in advance under the control of the called subscriber 22, for example, when the password is leaked, the change is also possible.

Therefore, when an initial activation (for example, power-on) for use of the guide bar 12 is performed in a state where the password for the guide bar 12 or the operator is registered in the data memory 24 ) In step 52, the guide board 12 displays a message requesting the input of a password through the display device 16. [

When the operator for operating the guide board 12 in response to the password input request message inputs the password from the input device 14 in step 54, the guide board 12 side confirms the password in step 56 And transmits it to the called subscriber unit 22 via the Q.921 link unit 28 and the Q.931 protocol unit 26.

Therefore, the called subscriber 22 determines whether the password input from the input device 14 matches the password registered in the data memory 24 in step 58. As a result of the determination, the input device 14 If the password input from the Q.931 protocol unit 26 and the Q.921 link unit 28 does not match the password registered in the data memory 24, 12 so that the guide board 12 displays a message indicating the unavailable state of the guide board 12 through the display device 16. [ According to the present invention, when a plurality of guide bands are connected to the called subscriber unit 22, if the password inputted to the guide bands 12 is judged to be unequal over several times, for example, 12 as an attempt for improper use of the guide board 12 and warning the operator of the guide board 12 of an unauthorized use of the guide board 12 can be employed.

On the other hand, if the password input from the input device 14 matches the password registered in the data memory 24 as a result of the determination in step 58, the called subscriber unit 22 sends the corresponding guide board 12 Is applied to the guide bar 12 through the Q.931 protocol unit 26 and the Q.921 link unit 28 so that the guide bar 12 can be used for a predetermined time period (Log-in) to the usable state of the guide board 12 corresponding to the display device 16. [0064]

Therefore, the guide board 12 performs processing for a special service function requested from the subscriber terminal 10, for example, under the operation of an operator who inputs a valid password by the input device 14. [

Here, an example of a special service function requested from the subscriber terminal 10 to the guide board 12 will be described. For example, when the calling subscriber occupying the subscriber terminal 10 makes a call connection with the third subscriber A call setup request from the subscriber terminal 10 is transmitted to the calling subscriber unit 18 so that the calling subscriber unit 18 requests the number translation unit 20 to translate the number.

The number translator 20 requests the called subscriber 22 to make a call in response to the number translating request of the calling subscriber 18, (For example, '12' in FIG. 1) available from at least one or more guide parties received via the Q.921 link unit 26 and the Q.921 link unit 28 to request a call setup from the subscriber terminal 10 .

Therefore, the operator of the guide line 12 to which the call setup request has been transmitted tries to make a call connection to the third subscriber requested by the subscriber terminal 12, and when the third subscriber is called, The call connection between the subscriber and the third subscriber is established, and in this state, the billing process for the talk time of the subscriber terminal 10 is executed.

When a call setup for the subscriber terminal accommodated in the exchange of another station is requested from the subscriber terminal 10, the number translator 20 transmits the subscriber's terminal 10 to the exchange of another station through the relay call processing unit 30, The call setup request is transmitted between the subscriber terminal 10 and the subscriber terminal connected to the exchanger of the other station.

When a call connection request for the subscriber terminal 10 is generated from a subscriber terminal accommodated in an exchange of another station, the call connection request is transmitted to the number translator 20 through the relay call processing unit 30, Accordingly, call connection is established to the subscriber terminal 10 through the calling subscriber unit 18, so that a call can be made between the subscriber terminal 10 accommodated in the exchange of another station and the subscriber terminal 10.

After the processing of the special service function of the guide board 12 executed in the above step 64 is performed, an input for requesting the stop of the corresponding guide board 12 from the input device 14 to the guide board 12 (YES at step 66), the guide board 12 displays a message requesting the input of a password on the display device 16 at step 68, and at step 70, When the password is input from the input device 14 in response to the message on the display device 16 (YES in step 70), the guide board 12 transmits the password to the Q.921 link part 28 and Q. 931 protocol unit 26 to the called subscriber unit 22. [

Therefore, the called subscriber 22 determines in step 74 whether the password input from the input device 14 and transmitted and the password registered in the data memory 24 coincide with each other. As a result of the determination, The result of disallowing transition to the dormant state with respect to the guide board 12 in question is transmitted through the Q.931 protocol unit 26 and the Q.921 link unit 28, (12).

Therefore, the guide board 12 is not shifted to the rest state while displaying a message indicating that the corresponding guide board 12 can not be hung on the display device 16, And alerts the operator of the other connected guide to the state of the unauthorized stopping request of the guide board 12 corresponding thereto.

On the other hand, if it is determined in step 78 that the password input by the input device 14 matches the password registered in the data memory 24, the process proceeds to step 78, The Q.931 protocol unit 26 and the Q.921 link unit 28 transmit the process result to the guide unit 12, The user enters a rest state.

That is, according to the present invention, when a password is assigned to at least one guidepost or operator provided for the entire electronic exchanger and permission of use of the guidepath is requested, or when a pause of the guidepath being used is requested, A normal use permission or a rest permission is made.

As described above, according to the method for controlling the operation of the guide band of the pre-set electronic exchanges according to the present invention, at least one guide band connected to the former electronic exchanges, or an operator handling the guide band, The use of the guide zone is allowed or the dormancy is allowed only at the time of inputting the information, so that the execution of the special service function by the guide zone or the maintenance of security against the billing process can be remarkably improved.
