Description

Guideway control method in electric switchboard

The present invention relates to a method of controlling a guide in a local electronic switchgear, and more particularly, by providing a password to an operator of at least one guide rod provided to a local electronic switchboard, the reception service function by the guide is provided. The present invention relates to a guide control method in a local electronic switchboard so as to enable normal operation of the guide only when the password is matched at the time of blocking or unblocking.

As is well known, an electronic switch is designed as a means for providing an optimized call service for call setup and call request generated in the subscriber terminal while a plurality of subscriber terminals are connected and applied to practical use as a national exchange means. It is a state.

According to the above-mentioned electronic switchboard, the subscriber station is connected to the call path network via a subscriber line, for example, including a semiconductor switch (i.e., a space switch and a time switch). Connections with other switching centers are made through trunks. The switchboard also includes a scanner that detects all events occurring on subscriber lines and trunks and notifies the control unit, for example, from the handset's on-off hook, dialing telephone number, and other stations. The incoming signal of the signal, the state of the relay line (collinearity or fire) are detected.

In addition, the electronic switchboard also includes a signaling device that is in charge of the processing of the signal to be transmitted on the line, the signaling device being, for example, under the control of the control unit, a dial tone, a busy tone, a call tone, a call signal current, A signal transmitted to another station's exchange is generated.

On the other hand, according to the above-mentioned electronic switchboard, if the format of the other station that accepts the other subscriber station which is the target of the call setup request generated from the subscriber of the own country is different from that of the own country, the direct call with the subscriber terminal of the other exchange is performed. Setting processing becomes impossible.

Therefore, in consideration of such a point, the OPS (Operator Position) is used to realize a call connection to a foreign exchange that adopts a different exchange method or to separately charge a subscriber's terminal. At least one System) is provided.

According to the provision of the information desk, a call compatible with the other party subscriber terminal connected to another switching center of a different exchange system by the operator's work in response to the call setup request generated at the subscriber terminal of the local exchange. Connection is possible.

On the other hand, if the information desk wants to leave the information desk for a while while the reception desk service is in progress for the subscriber in its country, or to stop the reception service in order to process the service for billing confirmation, reservation call, local call, etc. A block must be requested and authorized by the electronic switchboard. Similarly, in the case of resuming the reception service of the information desk where the incoming service is suspended, the electronic switchboard is requested to unblock the transfer. Normal operation is only possible with the approval of the electronic exchange.

However, as described above, in performing the state transition according to the block / unblock, the block / unblock request can be notified to the electronic switchboard by a predetermined key operation, so that it is not a specific operating permit for the guide. Any user (operating licensee) operates the information desk in the block state while the operator leaves the room for a while, and changes the information on the specific person, such as subscriber information or billing information, or changes the information in the block state. There is a problem that it is not possible to exclude the possibility that an operation such as providing an abnormal incoming service to a subscriber requesting a call connection by operating in an unblocked state.

Accordingly, the present invention has been made in view of the above-described circumstances, and the password is given to an operator of at least one information desk provided to a local electronic switchboard, and the reception service function by the information desk is stopped or restarted. It is an object of the present invention to provide a method of controlling a guide in a local electronic switchboard so that the block / unblock state of the guide is set only when the passwords match.

According to an embodiment of the present invention for realizing the above object, the licensed guide is required to request the block / unblock state of the guide, and the guide enters a unique number for the block / unblock state transition Comprising the step, the subscriber processing unit compares the inputted unique number and the pre-registered password, performing the block / unblocking process of the guide based on the comparison result of the password, the subscriber processing unit And controlling the guide according to the local electronic switchboard including the step of notifying the result of the block / unblock processing as the guide, and the guide bar transitioning to the block / unblock state based on the result notification from the subscriber processing unit. A method is provided.

Preferably, in the present invention, the password is uniquely assigned to each of the at least one guide, and the unique number is uniquely assigned to each operator who handles the at least one guide.

Preferably, in the present invention, the result of the comparison of the unique number and the password, if the input unique number and the pre-registered password does not match, the guide further comprises maintaining the current unblock / block state.

According to the present invention made of the above steps, when the block / unblock state transition of the guide to the electronic switchboard is required when a unique number consisting of the same number combination as the password already registered in the electronic switchboard is input from the guide Only when the transition to the block / unblock state of the guide is performed, it is possible to prevent the block / unblock state of the guide from being transitioned by any user except a specific operating license holder who recognizes the unique number. .

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.

Figure 1 is a block diagram showing the main part of a conventional electronic switch including a guide to which the present invention is applied.

In the figure, reference numeral 1 designates an accessible guide and a corresponding local subscriber in response to a call request from the local subscriber (not shown) accommodated in the electronic switchboard. The subscriber processing unit is configured to execute the transition to the usable state (Login) or the idle state (Logout) of the guide table OPS as required. In particular, in the present invention, the subscriber processing unit 1 is registered with a password for the block / unblock state transition of the information desk (OPS) is the same as the corresponding password when the block / unblock request from the information desk (4) Transition to the corresponding block / unblock state is possible only when a unique number is input from the guide 4.

Reference number 2 transmits a call connection request from any subscriber terminal (not shown) transmitted through the subscriber processing unit 1 to the guide 4 side or the unique number input from the guide 4 is the subscriber. Q.931 protocol section that executes the ITU-T Q.931 protocol to be delivered to the processing section 1 side.

Reference numeral 3 is a Q.921 signal interposed between the Q.931 protocol unit 2 and the guide 4 to signally connect the Q.931 protocol unit 2 and the guide 4. Link section.

Also, reference numeral 4 is provided to at least one of the electronic switchboards to provide subscribers with services corresponding to incoming services, reservation calls, delayed calls, billing confirmation, etc. based on the special service functions required by the subscriber terminal (not shown). It is a representative guide of the guide provided by the terminal. Particularly, in the present invention, the guide 4 is provided with an input means (not shown), and the guide 4 is assigned with a unique number for the block / unblock state transition by the operator through the input means. The state transition according to the block / unblock of the guide 4 is made only when the unique number of the same number combination as the previously registered password is input to the subscriber processing unit 1.

Hereinafter, with reference to the flow chart shown in Figure 2a and 2b attached will be described in detail the operation of the guide stand control method in the local electronic switch according to an embodiment of the present invention.

First, the state of the current guide 4 is determined (step 10), and if the current guide 4 is in a block state as a result of the determination, that is, the operator leaves the seat or checks the billing information, the delay call. If the service is being performed according to the reservation call (YES in step 10), the process proceeds to step 12 and waits for the unblocking request from the guide 4.

In step 12, if the operator of the guide 4 returns to the correct position or requests the unblocked state transition of the incoming service to terminate the service according to the charging information confirmation, delay call, or reservation call, the unblock request signal Is transmitted to the subscriber processing section (1) via the Q.921 link section (3) and the Q.931 protocol section (2).

Subsequently, when the operator inputs the unique number through the input means configured in the guide 4, the unique number signal is transmitted to the subscriber through the Q.921 link unit 3 and the Q.931 protocol unit 2. The subscriber unit 1 is notified to the processing unit 1 (step 14). Based on the notification result, the subscriber processor 1 transmits the unique number inputted from the information desk 4 to the registered password within the subscriber processor 1; It is determined whether or not it is the same (step 16).

As a result of the determination, if the unique number inputted from the guide 4 is not the same as the previously registered password (NO in step 16), the subscriber processing unit 1 determines that the unblocking request is inputted from the non-operator. The result of the block is notified to the guide 4, wherein the block result signal output from the subscriber processor 1 is transmitted through the Q.931 protocol unit 2 and the Q.921 link unit 3; The guide 4 is notified (step 18).

Therefore, the guide 4 notified of the block result signal returns to the initial state while maintaining the block state continuously (step 20).

On the contrary, if the unique number input from the guide 4 is the same as the registered password (YES in step 16), the subscriber processing unit 1 determines that the unblocking request is input from the operating license holder. After performing the unblocking process of (4) (step 24), the unblocking result is notified to the guide 4, wherein the unblocking result signal output from the subscriber processing section 1 is the Q.931 protocol section. (2) and the Q.921 link unit 3 are notified to the guide 4 (step 24).

Accordingly, the guide 4, which has been informed of the unblocking result signal, transitions from the block state to the unblocked state and then returns to the initial state (step 26).

On the other hand, if the state of the guide 4 determined in the step 10 is in an unblocked state, that is, performing an incoming service (NO in step 10), the process proceeds to step 30 to request a block request from the guide 4. Wait

In step 30, if the operator of the information desk 4 leaves the seat for a while or requests the block state transition of the incoming service to perform the service according to the billing information confirmation, delay call, reservation call, the block The request signal is notified to the subscriber processing section 1 via the Q.921 link section 3 and the Q.931 protocol section 2.

Subsequently, when the operator inputs the unique number through the input means configured in the guide 4, the unique number signal is transmitted to the subscriber through the Q.921 link unit 3 and the Q.931 protocol unit 2. The processing unit 1 is notified (step 32), and based on the notification result, the subscriber processing unit 1 inputs the unique number inputted from the information desk 4 and the registered password in the inside of the subscriber processing unit 1. It is determined whether it is the same (step 34).

As a result of the determination, if the unique number input from the guide 4 is not the same as the previously registered password (NO in step 34), the subscriber processing unit 1 determines that the block request is input from the non-operator. The unblocking result is notified to the guide 4, wherein the unblocking result signal output from the subscriber processing section 1 is transmitted through the Q.931 protocol section 2 and the Q.921 link section 3, respectively. The guide 4 is notified (step 36).

Accordingly, the guide 4, which has been informed of the unblocking result signal, returns to the initial state while continuously maintaining the unblocked state (step 38).

On the contrary, if the unique number input from the guide 4 is the same as the previously registered password (YES in step 34), the subscriber processing unit 1 determines that the block request is input from the operating license holder. After the block processing of 4) is performed (step 40), the guide table 4 is notified of the block result, wherein the block result signal output from the subscriber processing unit 1 is transmitted to the Q.931 protocol unit 2; The guide 4 is notified via the Q.921 link unit 3 (step 42).

Accordingly, the guide 4, which has been informed of the block result signal, transitions from the unblocked state to the block state and then returns to the initial state (step 44).

As described above, according to the method of controlling the guide in a local electric switchboard according to an embodiment of the present invention, a password is assigned to an operator of at least one guide rod provided to the local electric switchboard, By stopping or restarting the incoming service function, the block / unblock state of the guide can be set only when the password is matched, thereby preventing arbitrary manipulation of the block / unblock state of the guide by the unauthorized user.

Therefore, it is possible to exclude the case where information about a specific person, such as subscriber information or billing information, is leaked or changed by the operating license holder, or when abnormal incoming service is provided by the operating license holder, thereby improving reliability of the guide service. You can do it.
