The present invention relates to a method for checking subscriber shape information in an all-electronic switching system that accommodates analog and digital subscribers.

In general, the electronic switching system is composed of a distributed control system, and the call processing service for the subscriber is centered on an access switching subsystem (ASS). Each subsystem is composed of a portion to which subscriber lines are connected in hardware and peripheral devices for connecting various tones to achieve one service. Accordingly, in order for the call processing service to be normally performed in such a subsystem unit, the shape information of the apparatuses constituting the call processing service is normally configured, and a maintenance function for various state management is performed based on this information. However, there is a problem that the quality of service is degraded due to the misconfiguration of such information.

In order to solve the above problems, the present invention prevents the deterioration of service quality and verifies the normal service state, thereby making final subscribers based on the shape information of upper and peripheral processors in a hierarchical structure. The purpose of the present invention is to provide a method for checking subscriber shape information of an electronic switchgear that can systematically check the shape information of a subscriber line, which is a service unit, at the initial installation stage or during operation.

In order to achieve the above object, the present invention provides a method for checking subscriber shape information applied to an electronic switching system, comprising: constructing a subscriber shape management information in a database according to a type thereof and then starting service execution according to an operator command; step; A second step of checking the database to determine whether the subsystem is mounted and the status, and checking whether the peripheral processor belonging to the subsystem is mounted to check the shape information of the subsystem-specific subprocessor; A third step of checking the database and checking unit shape information for each peripheral processor by checking a state of a line number belonging to a peripheral processor and whether a card is mounted; And a fourth step of checking the shape information on the subscriber line for each unit by checking the database and confirming the unit type and whether the card and the line are mounted.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

FIG. 1 is a structural diagram of an analog and digital subscriber subsystem of an electronic switching system to which the present invention is applied, and includes an analog subscriber switching subsystem (ASS-S) 100 and a digital subscriber matching exchange subsystem (ASS-S).

The function proposed in the present invention is a subscriber receiving a command from an operator in a system data handler (SSDH) system which is a software block in the operation and maintenance processor 502 and receiving a distributed analog and digital subscriber. The service subsystem is configured to sequentially check necessary information through a database management system (DBMS) 102, and output the result information as a message.

Table 1 shows an implementation and status information database (R_MP_STATUS) for each subscriber service subsystem. This database manages the installation and operation status information of the main processor (MP: Main Processor) for each subsystem of the system including the subscriber service subsystem. The subscriber service subsystem except the fixed subsystem in the system configuration is a database. Has variable shape information according to the configuration method in system operation. Therefore, in order to perform the function normally in any system configuration, it should be done with reference to this database.

Table 4 shows a service configuration information database (R_MP_PP_STS) for each hardware unit. In this database, D_MP_PP_NO (4-1), which is the number of the peripheral processor that accepts the subscriber, is used to distinguish whether the subscriber type accommodated in the peripheral processor is analog or digital by D_MP_PP_TYPE (4-2). The location of the in-processor can be known through D_PP_LOG_NO (4-3).

And, the serial number of the subscriber line accommodated in the peripheral processor can know the start and end numbers by using D_START_LINE_NO (4-4) and D_END-LINE-NO (4-5).

Table 5 shows a subscriber line shape information database (R_SUB_UNIT_INF) for each hardware unit. This database is a database that configures whether a subscriber card is installed per unit constituting a peripheral processor that a subscriber is accommodated in. D_PP_TYPE (5-1) indicating a subscriber service type and D_PP_SEQ_NO (5-2) which is a serial number of the same service type. In case of a digital subscriber using the serial number D_SUB_UNIT_NO (5-3) of the unit, it is either Basic Subscriber Interface (BSI) or ISDN Primary Subscriber Interface (PSI) or ISDN Basic Rate Multiplexing. D_SUB_UNIT_TYPE (5-4) with information identifying whether it is Basic Access Multiplex Interface (BAMI), D_PP_CD_FST_NO (5-5), the first starting card number in the unit, and D_SUB_FST_NO (5-6), indicating the subscriber serial number. And D_CARD_EQ_INF (5-7) indicating whether or not each individual card is mounted.

Table 6 shows a subscriber line shape information database (R_LTI_CAP). This database is a database showing the number of subscribers to which each unit is accommodated according to the service type of the unit in which the subscriber is accommodated. The database includes D_ASI_UNIT (6-1) representing an analog subscriber and D_DSI_UNIT (6-2) corresponding to a digital subscriber. .

Table 7 shows a subscriber line shape information database (R_SLN_STS). This database includes D_EQP_STS (7-2) indicating whether or not to be mounted in D_SLN_NO (7-1), which is a line number, for all individual subscriber lines accommodated in the subscriber service subsystem, and D_MBLK_STS (7−) indicating whether or not isolated by the operator. 3) D_SOBS_FLAG (7-4) indicating subscriber monitoring, and D_TRC_FLAG (7-5) for call tracking purposes.

FIG. 2 is a flowchart of the entire process for checking the subscriber shape information according to the present invention, wherein the unit in which the subscriber is mounted is hierarchically structured into a subsystem, a peripheral processor in the subsystem, a subscriber unit in the peripheral processor, and individual subscriber lines in the unit. When the function is started by the operator request in the defined structure, after checking the feasible state (1), it is required to perform the function to check the configuration information of the peripheral processor, which is the peripheral processor for subscriber control by the subscriber service subsystem, which is the highest configuration information. (2) requesting the function to check the configuration information controlling the subscriber unit information for each peripheral processor if the execution is completed normally; and (3) finally, the configuration information for the subscriber line information for each subscriber unit if normal processing is completed. Perform process (4) to check and end.

3 is a flowchart illustrating a method for checking configuration information of a peripheral processor (PP) for each subscriber service subsystem according to the present invention, and checks whether or not a peripheral processor is mounted for accommodating subscribers for each subsystem in connection with a database for managing processor shape information. It is a process flowchart for doing this.

Upon receiving the execution request by the operator while the system is being installed and in operation (21), R_MP_STATUS, which is a database managing the implementation and status information for each subscriber service subsystem, is read (22). At this time, if the subsystem is not mounted, it outputs unmounted information on the corresponding subscriber service subsystem and terminates (34). If it is mounted, the upper processor controlling the subsystem is checked (24).

If the processor is in an abnormal state, abnormal information about the processor is output and terminated (35). If the processor is in a normal state, R_ASS_TYPE_INF, which is a database for checking an acknowledgment state of a peripheral processor accommodating a subscriber, is read (25).

If the peripheral service is not accommodated in the subscriber service subsystem, information indicating the non-acceptance state is output and terminated (36), and in the case of the accepted subscriber service subsystem, the mounting information of the peripheral processor is read (27).

If it is installed and checks whether the peripheral processor is installed (28), it reads R_MP_PP_STS, a database for checking subscriber information controlled by the peripheral processor (29). At this time, by checking whether or not the peripheral processor for controlling the subscriber is mounted (30) and outputs the information corresponding to the inconsistency of the peripheral processor shape information (31), if it is not mounted, it is determined that the normal state.

In the case of the non-mounting in the configuration check of the peripheral processor (28), the mounting information of the peripheral processor controlling the subscriber is read (37) and the mounting status is checked (38). (39), if not mounted, perform the next step.

If the above check is completed for one peripheral processor, check whether all the peripheral processors belonging to the subscriber service subsystem are checked (32). If not, update the peripheral processor number for the next check. (33) When the repetition process is completed and the whole check is completed, it is finished.

First, the database (R_LTI_CAP) is read (50) to obtain the number of subscribers accommodated in a unit of subscriber unit, and the database (R_MP_PP_STS is used to obtain the subscriber service type and the start and end number of the subscriber line of the peripheral processor belonging to the corresponding subscriber service subsystem. (51). The information obtained here is used to obtain a serial number of the same service type of the peripheral processor (52), and the unit information controlled by the peripheral processor is read from the database (R_SUBS_UNIT_INF) using the information (53).

Using the information read above, check whether the area of the line number controlled by the unit is normal (54). If abnormally allocated, output the line number error information (60, 62) and continue processing for the next unit. In case of normal allocation, check whether the card belonging to the number area is mounted (55), if not mounted, output the card unmounted information (61, 62) and continue processing for the next unit. If is installed, check whether the processing for the whole unit controlled by the peripheral processor is completed (56). If not, assign the unit number to process the next unit (58) and read the unit information. 53) is repeated. If the processing of the unit for each peripheral processor is completed, check whether the processing for all the peripheral processors belonging to the subscriber service subsystem is completed (57). The number is updated (59), and the process is repeatedly performed from the process of reading the peripheral processor information (51).

FIG. 5 is a flowchart illustrating a method for checking subscriber line shape information for each unit according to the present invention, wherein each unit unit belonging to a peripheral processor for controlling a subscriber line has a corresponding subscriber line configuration information corresponding to card-specific mounting information. This is a flow chart to check the mounting status.

The subscriber line configuration information per unit is read from the database R_SUB_UNIT_INF using the service type, serial number, and unit number of the peripheral processor belonging to the subscriber service subsystem (70). The information read here is used to classify whether the service type of the unit controls an analog line or a digital line (71), and sets the number of subscriber lines accommodated by one card according to each service type (72). , 73, 74).

Using this information, the start number of the subscriber line belonging to the card is calculated (75), and the database (R_SLN_STS) for checking the presence or absence of mounting in individual line units is read using this number (76).

At this time, it is checked whether the card is in a mounted state (77). If it is not mounted, it checks whether the subscriber line information is mounted (84). If it is not mounted, it is a normal state and the processing for the next card is continued. Since the mounting information is wrong, an error message for this is output (85) and processing of the next card is continued.

If the card is mounted, it checks the mounting state of the subscriber line (78). If it is mounted, it continues to process the next card because it is normal. If it is not mounted, an error message about the mismatch of the subscriber line information is output. And continue processing for the next card.

Then, check whether all processing for the card belonging to the unit is completed (80), and if it is not completed, using the number for the next card (82) repeats from the start number calculation process 75 of the subscriber line If it is completed, it checks the processing status of all units (81) and repeats from the unit type classification process 71 using the next unit number (83).

The present invention can be commonly used in all systems for providing subscriber services using the electronic switching system.

As described above, the present invention is a method for systematically checking components ranging from a subscriber service subsystem, which is a maximum unit for accommodating subscribers, to a minimum unit for managing individual subscriber information. And in the process of operation, it is possible to check the factors that may be caused by the inconsistency of the subscriber configuration information in advance to provide information that can be quickly taken action to minimize the failure of the system service and ensure the maximum system utilization efficiency . In addition, it is a method of accessing the contents of the database to obtain necessary information and using them to check each other. It is also possible to apply to make it possible.
