In FIG. 1, the relay line processing means 10 and the subscriber processing means 20 are illustrated in a single structure connected to the switch processing unit 30, but in practice, a plurality of ASSs are connected to the switch processing unit.                     

Each component described above will be described in more detail.

The relay line processing means 10 has an overall control over the call processing and an ASP 15 which performs control for performing an operation and maintenance function, and is connected to the ASP 15 and under the control of the ASP 15. N relay line processing units for performing call processing, and although not shown in the drawing, a time switch, a signal and guidance broadcasting apparatus, a test apparatus, and the like.

In particular, the ASP 15 is assumed in the present invention MDGC (15a) to perform a function of collecting a series of data for the performance measurement for the space switch, the number of occupancy attempts, occupancy failure of the space switch during call processing The software includes the MSLC 15b which performs the count function for the number and the like, the CSL 15c which stores the time occupied by the space switch during the call processing, the information on the originating / receiving ASP, the call processing library, and the like.

The subscriber processing means 20 differs only in that the call processing target is a general subscriber, and the other configuration or operation is similar to the internal configuration of the relay line processing means 10 described above, and thus the relay processing means ( The description of the internal configuration of 10) will be omitted.

The MDGC, MSLC, and CSL are also mounted in the ASP 25 configured in the subscriber processing means 20.

The switch processing unit 30 shown in FIG. 1 includes a space switch for setting a path for call processing and an INP 35 for controlling the operation of the space switch. The INP 35 is available in the present invention. The INMH 35a is loaded which generates the degree data and provides the generated availability data upon request from the MDGC 15a.

In addition, the central control system 100 is an interface unit 110 for interfacing between processors of each subsystem to enable inter-processor communication, OMP 120 for performing the overall operation and maintenance of the system, The operator terminal 131 is connected to the MMP 130 to perform the function of analyzing the MMC instruction input from the operator terminal 131 and delivers the MMC instruction to the relevant block.

Here, the OMP 120 is loaded with the MSDP (120a) for performing statistical processing according to the performance measurement of the space switch, the MMP is loaded with the MMS (130a) for MMC command analysis, the OMP (120) The 121 and the MT (Magnetic Tape) 122 are connected to store the statistical processing result according to the performance measurement of the space switch in the disk 121 or the MT 122, and the MMP 130 has a terminal ( 131, the printer 132, and the disk 133 are connected to output the performance measurement results of the space switch through the printer 132.

Hereinafter, with reference to the message flow diagram shown in Figure 2 will be described in detail the method of measuring the space switch performance in the time division electronic switch according to an embodiment of the present invention.

First, when the electronic switch is initially driven, MSDP_main 120a1 of the MSDP 120a is started to start MSDP_init 120a2, which is a process of receiving an MMC instruction (S10), and the MDGC_main 15a1 is also started to MMC. The MGDC 15a2, which is a process for receiving a command, is started (S12).

When the subscriber attempts to call, the ASP 25 requests the number translation unit 40 to translate the number, and the result of the number translation is reported, and the ASP 25 sets the call path according to the number translation result. When the occupation of the space switch is requested, the MSLC 15b counts the occupancy attempts, occupancy, and failures according to the occupancy result of the space switch.

The CSL 15c records the occupancy start time when the space switch is occupied to measure the occupancy time, and calculates and stores the occupancy time when the call is completed.

In this state, when the MMC command according to the space switch performance measurement is input through the terminal 131, the MMS (130a) transmits the MMC command to the MSDP_init (120a1) of the OMP 120, the MSDP_init (120a1) Starts the child processor MSDP_odse 120a3, which performs the space switch performance measurement operation corresponding to the MMC instruction, to perform a series of operations according to the space switch performance measurement.

Meanwhile, a space switch performance measurement period is designated through the MMC command. The MSDP_odse 120a3 transmits a data collection request message DGaReqC to the MGDC_init 15a2 at a start time (0 minutes) (S18).

Accordingly, the MGDC 15a2 starts the MDGC_ssw 15a3, which is a child processor for performing data collection operation according to the space switch performance measurement (S20), and the MDGC_ssw 15a3 periodically performs INMH (of the INP 35). Request for collection of the availability data to 35a) to collect the availability data stored in the INMH 35a (S22).

For reference, the availability data is information on the number of channels mounted and the number of channels actually available, and the number of IPC (Inter Processor CommuniGation) channels is calculated based on the number of channels and the number of available channels.                     

On the other hand, if it is determined that the time set for the space switch performance measurement in the MSDP_odse (120a3) has elapsed from the start time, that is, 5 minutes, the data transmission request message (GaDTxReq) is transmitted to the MDGC_ssw (15a3) (S24). ).

By the request, the MDGC_ssw 15a3 collects count values for the space switch occupancy attempt number, the occupancy number, and the failure number performed in the MSLC 15b (S26), and the called / incoming ASP stored in the CSL. Information and the total time that each ASP occupies the space switch, that is, the total occupancy time, are collected, and traffic information is generated based on the total occupancy time (S28).

Next, the average availability is calculated based on the collection result, and the space switch occupancy attempt count, occupancy count, count value for the failure count, information on the call origin and destination ASP, information on the total occupancy time for each ASP, traffic The data transmission message GaDTx including the information is transmitted to the MSDP_odse 120a3 as a result of the space switch performance measurement (S30).

The MSDP_odse 120a3 processes the data transmission message GaDTx so as to be suitable for an output format so that the number of spatial switch occupancy attempts, occupancy, failures, mounted channels, and available channels for each incoming ASP for each ASP is obtained. Process the IPC channel, total occupancy time, and traffic information.

Subsequently, the spatial switch performance measurement result processed by the output format by the MSDP_odse 120a3 is transmitted to the MMC 130a (S32), and the MMC 130a controls the spatial switch performance by the control of the MMP 130. The measurement result is output through the terminal 131 and stored in the disc 121 and the MT 122 under the control of the OMP 120.

According to the method and apparatus for measuring the space switch performance in the time division electronic switch according to the embodiment of the present invention as described above, by outputting the space switch performance measurement results periodically or at the request of an operator, By reporting the number of occupied attempts, occupied, failed, mounted channels, available channels, IPC channels, total occupancy time, and traffic information to the operator, exchange operators can efficiently reconfigure network configurations, subscribers and relay lines. It has the effect of making it possible.

On the other hand, the present invention is not limited to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, such modifications and changes should be regarded as belonging to the following claims. will be.
