Description

Performance test method of Access Switch Subsystem in Electronic Switching System}

The present invention relates to a subscriber matching subsystem performance test method of an electronic exchange. The present invention relates to a method of testing an electronic exchange by storing a load box that generates a call in the same manner as a normal call processing routine in a firmware of a device controller closest to a subscriber station. The present invention relates to a method for testing the performance of an Access Switch Subsystem (hereinafter referred to as an ASS).

In order to measure the performance of the subsystem of the large-sized exchange, a method of testing by installing a call generator (local call generator (LCS), relay call generator (UCS)), which is a device that performs the same role as a real terminal, was used. .

However, there is a problem that the above method cannot be applied to the current TDX-100 electronic exchange, and the current TDX-100 electronic exchange increases subscriber capacity and call processing capacity of the subsystem of the existing TDX-10A exchange more than four times. It is impossible to measure the performance using a real terminal without installing the entire system in the field (accommodating 32,000 subscribers and processing 200,000 BHCA).

In addition, there is a method of generating a virtual call in the main processor (MP) as a similar function, but in this case, it ignores a large part of the normal call processing process and processes the communication between the main processor and the processor of another subsystem (IPC) message. There is a problem that can only measure the load related to.

In the present invention, in view of the above-described conventional problems, an object of the present invention is to provide a performance test method for measuring the performance of not only the main processor but also peripherals and processors (TP) in charge of real-time processing. do.

In the performance test method of the subscriber matching subsystem of the present invention for achieving the above object, in the performance test method of the subscriber matching subsystem of the electronic exchange, the signal matching with the subscriber board, and the calls generated from the subscriber board Generating the same information as a hook_off signal by a load box stored in firmware of a condensing device controller and transmitting the same information to a processor (TP) that performs peripheral processing and real-time processing; a response to the hook-off signal; Receiving a connection request from the TP and the main processor to the subscriber line concentrator, repeatedly connecting the concentrator and transmitting the same signal to the TP one by one after receiving the digit from the called subscriber; Subscriber line concentrator sent by TP and main processor in response to subscriber digit reception Receiving a connection request and a ring connection request; and processing the received signal and transmitting a called party hook_off signal to the TP to inform the called party of the answer, and then requesting to disconnect the ring to release the ring connection. And maintaining the communication path for a predetermined time while the communication path is connected through the above process, and transmitting a first hook on signal and a second hook on signal to the TP to indicate recovery start; And receiving a disconnect request signal with the subscriber line concentrator from the TP in response to the signal and recovering the call.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram showing the structure of an ASS 1 to which the present invention is applied, and a subscriber board 11 accommodating a subscriber station;

A device controller which is responsible for signal matching with the subscriber board 11, aggregates calls generated from the subscriber board, and stores an incoming / outgoing load box (not shown) that generates the same signal as when a normal call occurs. 12);

A peripheral device for transmitting the digits received from the device controller 12 to the main processor and a processor (hereinafter referred to as TP) 13 for performing real time processing;

A main processor (MP) 14 which plays a major role related to call processing, such as receiving additional digits necessary for station number translation and reception for the call transmitted from the TP 13;

It is provided with a time switch 15 for connecting the call path with the subscriber terminal through the device controller 12.

In addition, the ASS 1 performs a station number translation and a called number translation on a digit transmitted from the main processor 14 to establish a path for connection with a called subscriber (Interconnection Network Subsystem: INS) ( 2) and;

It is connected to the central control system (CCS) (3) for controlling the operation of the internal connection network subsystem (2).

For reference, the load box corresponds to software, and functions to generate signals generated in a normal call processing process instead, and stores the same in the device controller 12 so that the load box can be performed.

In the normal operation of the ASS (1) configured as described above, the call processing process will be described by receiving a call request from a subscriber station (e.g., PSTN phone, CTPM phone, data terminal, etc.) by dialing and transmitting the information to the TP (13). The TP 13 forwards the received digits to the MP 14.

The MP 14 receives additional digits necessary for station number translation and incoming call to the digit and transfers the digits to the internal network subsystem (INS) 2 to determine a path for translation and subscriber connection of the called party.

In addition, if the status of the called subscriber is checked and the receiver is in the normal state, the call connection is performed through a communication message between the processors (hereinafter referred to as IPC) to the MP and TP to which the called subscriber is subscribed.

As shown in this call processing process, the load by call processing occurs in the process of transmitting / receiving and processing an internal message called IPC between exchange processors. By executing the credit load box software, the contents of the IPC and the number of IPCs required for call processing in the TP 13 and the MP 14 of the exchange ASS 1 are set to be the same as the normal call processing. And TP 13 can be measured simultaneously. In particular, the load box is stored in the firmware of the device controller 12 to have the same load as normal call processing and to generate a large number of calls.

The operation of the load box as described above is as follows.

First, as shown in FIG. 2, the originating process of the load box generates the same information as if the receiver hook_off the telephone to make a call from the subscriber's telephone connected through the subscriber board 11. Transfer to TP (13).

The TP 13 and the MP 14 perform the same processing on the signal as in the normal call processing, and then request the subscriber shelf to access the Digital Line Concentrator (DLC). After connecting the concentrator, it is assumed that the receiving subscriber's digits to be received from the subscriber are transmitted to the TP 13 one by one.

Next, as shown in FIG. 3, the incoming call processing of the load box is performed. The TP 13 and the MP 14 receiving the digits of the incoming subscribers receive the digits and process the number translation in the same way as the normal call. Attempt to connect as an incoming subscriber.

In the load box that performs the incoming processing, it receives and processes the connection request and the ring connection request with the subscriber line concentrator (DLC) and transmits the incoming subscriber hook_off signal to the TP 13 to inform that the called party has responded, and the ring cutting request is made. To disconnect the ring.

Referring to FIG. 4, a recovery process after maintaining the call path by maintaining a predetermined time in the state in which the call path is connected through the above process is described with reference to FIG. 4. Upon sending the ON signal and the second hook ON signal, the TP 13 accordingly sends a disconnect request signal with the subscriber line concentrator DLLC to recover the call.

All of the above processes are recorded in statistics and billing in the same way as the call made by the general subscriber, and this process is performed sequentially for each subscriber line at the exchange to directly carry out actual subscribers or call generators (LCS, UCS). You can generate as many bulk calls as you want without connecting.

For reference, the present invention has been described with reference to the PSTN call as described above, the same performance measurement by storing the load box in the firmware of the device controller for not only the PSTN, but also ISDN, relay call Of course, the signal generated from the load box should be generated the same signals as the signal generated during the processing of the PSTN, integrated information communication network, relay call.

As described in detail above, the present invention provides a device controller which is a position closest to a subscriber board in the case of an exchange in which a processing capacity of an ASS is increased such that the performance cannot be measured under conditions such as a normal operating environment. The advantage of storing the load box in the system is that the call processing, billing, and statistical functions can be measured in the same environment as using the actual terminal to generate many calls.

In addition, preferred embodiments of the present invention are disclosed for the purpose of illustration, those skilled in the art will be able to various modifications, changes, additions, etc. within the spirit and scope of the present invention, such modifications and modifications belong to the following claims You will have to look.
