Description

{Perfomance test method of call processing capability in Electronic Switching System}

The present invention relates to a call processing performance test method of an electronic switch, and more particularly, to measure the call processing capacity of the exchange in an environment similar to the case of using an actual terminal, an internal connection network subsystem (Interconnection Network Subsystem) to be measured. The present invention relates to a method of measuring a maximum call processing capacity of an exchanger by mounting a load box on 24 Access Switch Processors (hereinafter referred to as ASPs) which are distributed outside the INS).

In order to measure the call processing performance of a conventional large-scale exchange, a test method was installed 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.

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 has more than four times the subscriber capacity and call processing capacity of the existing exchange (eg TDX-10A). It is not possible to measure the performance using the actual terminal without the whole system installed in the field (32,000 subscribers, 200,000 BHCA treatment), and the structure and new functions have been added. There is a problem that cannot be applied.

It is an object of the present invention to provide a method capable of easily measuring the maximum call processing capacity of an exchanger using 24 ASPs distributed and existing outside of the INS to be measured in view of the conventional problems as described above. It is done.

Outgoing signals (DODs) and these calls can occur simultaneously at any rate.

As such, the virtual call generation message generated in the load box mounted in each ASP 11 is transmitted through a time switch link (TSL) and an optical link through a message switch control interworking unit (MSCIU) 14 in the ASS (1). The data is transmitted to the super performance control interworking unit (hereinafter referred to as SPCIU) 4 of the INS 2.

The SPCIU 4 of the INS 2 then delivers the message to the main processor (or INP 21) or the packet handling module (not shown) (PHM) according to the destination of each message.

Upon receiving the call origination message, the INP 21 interacts with the loadbox according to the requested call type to process the call and terminate normally.

The received NTR 211 is a response signal, which signals that the station number has been translated. Send (intCallRP) (A1). Subsequently, the load box 111 transmits an initial signal (CdNoTranRQ) (B) requesting translation of the called party number to the NTR 211 and receives a signal (CdSubsSzRQ) (B1) of notifying the called party translation result in response thereto. .

When the translation of the number is completed, the load box 111 transmits a signal SwChConnRQ (C) requesting a connection according to the called number to the SNC 212, and receives a response signal SwChConnRP C1 thereto. Recognizing that the connection is completed, a signal (SwChRelRQ) (D) requesting disconnection is sent to indicate that the call processing test was completed successfully.

The NTR 211 that receives the transmission transmits a signal (TransitCallRP) A1111 that notifies the station if the translation result of the relayed station number is the same as the station number and the time point of the relay line occupied.

The process of testing the AIN call through the load box 111 in the above state (however, the signals according to the example represent only when the local call processing is successful) will be described.

First, a signal (AIN_SFCGPidRQ_SG) (F) requesting the processor identification number of the SFCG 214 in the INP 21 is transmitted from the load box 111 to the SFCG 214 and the processor identification number of the SFCG 214 in response. Receive a signal (AIN_SfcgPidRP_GS) (F1) indicating. The ear load box 111 transmits a signal (AIN_SfcgTreatReq) (G) requesting to determine whether to perform the intelligent network call input to the SFCG 214, and whether or not to proceed or terminate the call in the received SFCG 214. Sends a signal (AIN_SFResp) (G1) to determine the response.

Subsequently, the load box 111 transmits a signal (PfxTranTrkRQ) (A), which requests translation for the relay number, to the NTR 211, and the NTR 211 notifies that the translation number is a relay code in response. (TransitCallRP) (H) and a signal for requesting relay line occupancy to RCO (213) while transmitting a signal (OutgoingCallRP) (H1) that is notified if the station number is the same as another station and the station length and the trunk line occupancy point (RoutingRQ). (E). In response, the RCO 213 sends a signal OgtSzRQ_RC E111 requesting the outgoing line occupation to the load box 111.

Accordingly, when the number translation and relay line occupancy request is completed, the load box 111 sends a signal (SwChConnRQ) (C) requesting the connection according to the relay call to the SNC 212, and the SNC 212 sends an SSL 215. Send a signal (SswConnRQ) (C-1) to request a space switch connection. In response to this, the SSL 215 transmits a response signal (SwChConnRP) C1 to the load box 111 in response thereto, and the load box 111 receiving the signal recognizes that the connection is completed and requests disconnection. The signal SwChRelRQ (D) is sent to the SSL 215, and the SSL 215 sends a response signal SwRelRP D1 to the SNC 212. The call processing test is thus completed successfully.
