Description

Method of priority call relaying in operating position system {METHOD FOR TRANSITTING PRIORTY CALL IN OPERATING POSITION SYSTEM}

The present invention relates to an operating position system (hereinafter, abbreviated as OPS) of a national exchange. Particularly, an idle OPS occurs after registering a priority call using an operator terminal. The present invention relates to a priority call relaying method in OPS which enables the priority call to be forwarded first.

Typically, a local exchange is an Access Switching Subsystem (abbreviated ASS) and an Interconnection Network Subsystem (abbreviated INS) and a Central Control Subsystem (hereinafter abbreviated INS). , Abbreviated as CCS), and optionally include OPS.

Here, the ASS includes a subscriber and a local service interface, a time switch, a frame relay handler, an optical subscriber access device, a signaling device, a packet handler, and the like, and most call processing functions. It is a subsystem having a horizontally distributed structure systematically as it increases in units of ASS if necessary, and the INS is connected by using optical fiber elements between ASSs or ASSs and CCSs. A subsystem that generates and distributes system clocks with number translation, route control, space switch network control, and network synchronizer. CCS performs system operation and maintenance functions. Network management, test and measurement, billing statistics It is a subsystem that controls to perform input / output control, dialogue function between other systems.

As described above, ASS and INS are interfaced using an optical fiber element, and the interface with CCS uses an inter processor communication method. That is, in a system using the OPS, outgoing signals are received through the OPS, and the incoming process requires a separate operator control. The OPS is optionally configured to mean a system that is installed in a large power station or a gateway station to connect a call under the control of a separate operator.

On the other hand, in case of an emergency, that is, a calling subscriber belonging to a national intelligence agency or a special agency needs to send information about confidentiality to a called subscriber promptly, but waits based on the call connection request order, and then is connected. Therefore, there is a problem that the work efficiency that needs to be promptly processed is considerably degraded.

Accordingly, the present invention has been made to solve the above-described problems, the object of which is to register a priority call for differentiating call connection class, and if the idle OPS occurs, the priority call is relayed first. It is to provide a priority call relaying method in OPS.

In the present invention for achieving the above object, the priority call relaying method in OPS is a priority call relaying method using an operating position system at an exchange in which a call connection class is selectively stored according to subscribers, and a call connection request message from subscribers is provided. Determining whether there is an operating position system in an idle state if is provided; Providing a call connection request message to the operating position system in the idle state if there is an operating position system in the idle state, and operating in the call waiting state if there is no operating position system in the idle state; Determining whether a call access class is stored for a subscriber who has transmitted a call access request message in a call waiting state; If the call connection class is stored, providing the call connection class to the operating position system so that the operating position system displays to the operating position system operator the call connection class for the standby subscriber.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the present invention.

1 is a block diagram to which a priority call relaying method in an OPS according to a preferred embodiment of the present invention is applied and includes an operator terminal 10, a CCS 20, an ASS-S 30, and an ASS-I. 40 and a plurality of OPSs 50.

The operator terminal 10 generates a call connection class message for setting the call connection class for the calling terminal A by the operator (not shown) and transmits it to the CCS 20.

CCS 20 is a subsystem that performs not only system level operation, test and measurement, statistical functions, but also mass storage control management, various input and output door control functions with the operator, and data channel connection functions with other systems. And a comprehensive service digital network data handling (ISdn Data Handling: &quot; ISDH &quot; hereinafter) 22 and a database (DataBase: hereinafter &quot; DB &quot;) 24.

The ISDH 22 transmits the call connection class message of the operator terminal 10 to the ASS-S 30 and the ASS-I 40 through an inter processor communication cable C, while the DB ( Save to 24). The ISDH 22 finds a domain corresponding to the OPS class among the relations storing the subscriber message in the DB 24 to store the call access message in the DB, and sends the originating terminal A to the corresponding domain. Update the call connection class message for.

The ASS-S 30 includes subscriber and relay line matching, time switches, various signaling devices, packet handlers, and the like to perform most call processing functions and self-operation maintenance functions. A subsystem connected to the system includes an operating call control block (hereinafter referred to as OPCC) 32 and a DB 34.

The OPCC 32 stores the call connection class message from the ISDH 22 in the DB 34. When the call connection request message is received from the calling terminal A used by the subscriber, the OPCC 32 receives the received call connection request message. It transmits to ASS-I 40 connected to the called terminal through INS (B).

The ASS-I 40 includes a relay line matching, a time switch, various signaling devices, a packet handler, etc. to perform most call processing functions and self-operation maintenance functions, and in particular, as a subsystem connected to an ISDN subscriber. , OPCC 42, DB 44, Operating System Interface (hereinafter referred to as OPSI) 46, and IDN Basic access board (ISDN Basic access 2b1Q board Assembly: hereinafter referred to as IBQA). 48).

The OPCC 42 stores the call connection class message from the ISDH 22 in the DB 44, and the call connection request message from the originating terminal A is transmitted through the ASS-S 30 and the INS (B). When received, it is searched for the presence of OPS (50, ...) and is called by the idle OPS (50 ...). However, if the idle OPS (50, ...) does not exist, the ringback tone is connected to the corresponding calling terminal (A) and the call connection class for the calling terminal (A) stored in the DB 44 is set. If the subscriber is confirmed and registered in the priority call, the call waiting message of the subscriber and the call waiting message indicating that the call is waiting is transmitted to the OPSs 50, ... through the OPSI 46 and the IBQA 48.

When the OPS 50 receives a call waiting message indicating that the call connection class and call of the subscriber is waiting from the OPCC 42, the OPS 50 starts to light up when the number is counted on the display window of the weighting queue corresponding to the subscriber's class. The operator then recognizes that the call that is prior to the call he is currently in progress is currently waiting and takes the next action. In addition, the OPSs 50 also display the number when a plurality of calls having the same call connection order are in a standby state.

In addition, the OPCC 42 is configured to connect the highest priority call when the idle OPS (50, ...) is generated and to reduce the number of standby calls of the same call connection class as the connected call. . At this time, the OPSI 46 receives the call connection request message from the OPCC 42, adjusts the received call connection request message to the OPS format, and sets the level 2 header of the formatted call connection message to level 3; Attach to message and send to IBQA 48. Then, the IBQA 48 is a block that interfaces between the OPSI 46 and the OPS 50,..., And receives the call connection message from the OPSI 46, and then transmits the received call connection message to the OPS 50. , ...).

With reference to the flowchart of FIG. 2, the priority call relay method in OPS which concerns on this invention which has the structure mentioned above is demonstrated in detail.

First, when a corresponding subscriber having an originating terminal A requests the operator for a call connection class for the terminal, the operator uses the operator terminal 10 to send a call connection class message for the originating terminal A to the ISDH 22. To transmit.

Upon receiving the call connection class message from the operator terminal 10, the ISDH 22 transmits the call connection class message of the originating terminal A to the OPCCs 32 and 42 through the interprocessor communication cable C. Stored in the DB (24).

OPCC (32, 42) receiving the call connection class message for the originating terminal (A) from the ISDH 22 stores the received call connection class message in the DB (34, 44).

When the call connection request message is transmitted from the originating terminal A in this state, the OPCC 32 transmits the call connection request message to the OPCC 42 through the INS B (step 201).

Having received the call connection request message of the originating terminal A via the OPCC 32 and the INS B, the OPCC 42 sends an idle connection request message to one of the OPSs 50, ... It is determined whether one OPS (50, ...) exists (step 202).

If there is an idle OPS (50, ...) in the determination step 205, a call connection request message is transmitted to the idle OPS (50, ...) (step 203). On the other hand, if the idle OPS (50, ...) in the determination step 205 does not exist, a ringback tone is connected to the calling terminal A, and the calling terminal stored in the DB 44. By checking the priority class of (A), it is checked whether the subscriber is registered in the priority call (step 204).

If it is not the subscriber registered to the priority call in the check step 204, it is not applied to the present invention and becomes a general call waiting state (step 205). On the other hand, if the subscriber is registered to the priority call in the check step 204, the call waiting message and the corresponding call connection priority indicating that the call of the calling terminal A registered in the OPS call access class is waiting, the OPSI 46 and Send to OPS 50 via IBQA 48 (step 206).

The OPSs 50 display the call number of the waiting call and the waiting call, and the number of waiting calls having the same call connection rank on the respective monitors based on the information. Thus, the operators of the OPSs 50 can switch the OPS 50 to the idle state by viewing the call connection rank of the waiting call and, if necessary, by disconnecting the call in the connected state (step 207).

On the other hand, after the ring back tone is connected, an internal timer (not shown) is operated to determine whether the ring back tone has been transmitted for a predetermined time (step 208). When the ringback tone is transmitted for a predetermined time in the determination step 208, that is, it is determined that idle OPS (50, ...) does not occur, and a call release message is sent to the calling terminal (A) requesting a call connection. The call is released and the call is released (step 209). On the other hand, if the ringback tone is not transmitted within the predetermined time in the determination step 208, i.e., the idle OPS 50, ... is generated, the OPCC 42 determines that the idle OPS 50,. After confirming that there is a ..., the call connection request message of the originating terminal A having the highest priority is transmitted to the idle state OPS (step 210).

Therefore, the highest priority call is connected to the called terminal call through the OPS 50. As a result, the number of calls in standby is reduced, and the OPS 50 reduces the number of waiting calls having a call connection class corresponding to a call connected on the monitor by one display, so that one of the waiting calls is connected. ) Allows the operator to easily know (step 211).

Therefore, by registering and processing a call connection class message for the originating terminal A, when all of the OPSs (50, ...) are in a call, the priority call having the highest priority corresponding to the call connection class can be promptly performed. By connecting the call and displaying the waiting status of the call with the priority order set on the OPS 50 monitor, the OPS 50 operator can release the connection of the general call and preferentially connect the emergency call.

The present invention as described above can register and process the call connection class of the calling terminal used by the subscriber, and when the OPS is all in the call, by displaying the number of calls and the priority of the call on the OPS monitor In other words, it is possible to preferentially connect a high priority call under the control of an OPS operator.
