Description

A method of management for subsystem configuration in ATM switching system and a method of configuration for subsystem in it

The present invention efficiently proceeds with the configuration change of the subsystem when the configuration of the exchange subsystem unit is required due to the addition of subscribers and services that occur during operation in a distributed exchange system such as an ATM switching system. It is an object of the present invention to provide a method for reconfiguring a subsystem that does not cause interruption of service by maintaining a functional relationship and a hierarchical relationship between shape information in changing internal connection shape information in a subsystem of the system.

The present invention provides a sub switch of an ATM switch for performing a function of efficiently changing the subsystem configuration when a change in the subsystem configuration of the exchange due to the addition of subscribers and services occurring during operation in a distributed exchange system such as an ATM switching system is required. A method for configuring system shape information and a method for managing the shape information thereof.

Conventionally, the reconfiguration process of the exchange subsystem unit according to the increase of the exchange service is inactive for all the processors of the exchange operated in redundancy after generating the exchange station data reconstructing all the shape information inside the exchange from a computer system outside the exchange. In the process of replacing all the processors after the new exchange program and all the functions of the program were reloaded. Therefore, regardless of the amount of expansion, additional work was required to always go through external work steps and apply the service data already in operation to newly developed exchange data. In addition, such a shape change procedure has a possibility of causing an interruption of the exchange service due to a failure that may occur during the transfer operation of the processor.

Accordingly, the present invention minimizes external work in changing the shape of the exchange subsystem, such as an increase in capacity that occurs during exchange operation, and in accordance with a subsystem that changes communication channel information between each subsystem of the current exchange system in operation. As a proper maintenance method, for this purpose, it proposes a method of internal shape change, establishes a system of information construction method to maintain the consistency among the shape information, and the relationship between the shape information that may occur when changing the subsystem shape of the exchange. We propose the function to add / delete the change of subsystem configuration to prevent the malfunction of internal functions due to the loss of sex. Each exchange resource that executes the exchange function has a relational and hierarchical characteristic by functional characteristics, and can use this characteristic to establish the functional flow of the initial configuration and reconfiguration of the exchange shape. Through this established functional configuration method, it is intended to provide a technical basis of exchange resource configuration management that operates smoothly without interruption of service during operation in the initial configuration of exchange resources.

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

1 is a structural diagram of an ATM switching system to which the present invention is applied.

The ATM switching system consists of one or more distributed ATM Local Switching Subsystems (ALS) 3 and an ATM Central Swtiching Subsystem (ACS) 4. Subscriber Switching Subsystem (ALS) has a built-in Access Switching Network Module (ASNM) 7, a local switch module, and a Call and Connection Control Processor (CCCP) for user call processing and maintenance. Is implemented to handle functions including call service, and consists of subscriber interface module (SIM) 5 for subscriber matching and trunk interface module (TIM) 11 for relay call matching.

The ALS acts as a concentrator with an n: m concentrating ratio where the number of user-side links (6) is n and the number of switch-side links (9) is m, and the ACS performs interconnection between subscriber ALSs for high capacity systems. It acts as a dispensing device. The call request from the subscriber enters into the subsystem via the subscriber link 2 connected to the SIM and the middle call is acknowledged to the subsystem via the trunk line link 2. ACS is in charge of the connection and operation maintenance functions between ALS, and ACS implements ISNM (Interconnection Switch Netwoork Moduie) that is in charge of the connection between ALS. In the ACS, OMP (Operation and Maintenance Processor) 13 is provided to maintain the operation of the entire system, and the system-wide maintenance, test, measurement and statistics functions as well as various input / output statement control functions with the operator are performed. Status information and operational information of the exchange are output in text or graphic form. The workstation, which provides the interface with the user and visualizes the information, is connected to the exchange as an operating system (15) and the connection protocol uses Ethernet. (14)

2 is an example of a switch connection diagram of an ATM switch of the present invention. As an example of ALS00's switch number assignment, it is connected to ports 0, 1, 8, and 9 of ASNM's SMLA 0, 1, 8, and 9, and connected to ports 0, 1, 2, and 3 of SMLA 0 of ISNM0 (18). Ports 16, 3, 10 and 11 are connected to ports 16, 17, 18 and 19 of SMLA 1 of ISNMO. (19) Ports 16 to 29 of the ASNM are connected to the matching circuit and port 31 to the CCCP. (17) In the case of ALSO1, ports 0, 1, 8, and 9 of SMLA 0 of ASNM are connected to ports 4, 5, 6, and 7 of SMLA 0 of ISNM0, which is the central switch (18). Ports 2, 3, 10, and 11 are connected to ports 20, 21, 22, and 23 of SMLA 1 of ISNM0. (19) Ports 16 to 29 of the ASNM are connected to the matching circuit and port 31 to the CCCP. (21) The switch is also used for message communication between the processor and the controller inside the exchange.In FIG. 2, in order for the CCCP of ALS00 to be transferred to the CCCP of ALS01, the CCCP sends a message to port 0 of the ASNM (23). It is necessary to know the information forwarded to the port 31 of the ASNM of ALS01 via port 4 of ISNMO (24). In contrast, in case of CCCP of ALS01, a message is transmitted through port 0 of ASNM 24, port 23 of ISNM 23 and port 31 of ASNM of ALS00. As such, each processor must maintain information on an internal communication path for transmitting and receiving messages between each processor.

3 is a diagram of configuration information between subsystems of the ATM switch of the present invention.

The OMP of the ACS includes the configuration information 29 of the subsystems of the ATM exchanger, the channel configuration information 30 for internal message communication with each subsystem, the rack configuration information of the ACS subsystem, and circuit configuration information mounted on the ACS. (26) In the ALS, the channel configuration information 30 for message communication with other subsystems, the rack configuration information of the ALS, the circuit configuration information of the circuit mounted on the ALS, the configuration information of the switch, the configuration information of the matching unit, Matching part link configuration information and switch link configuration information are located. (27, 28) Subsystem configuration information is composed of a subsystem number and subsystem implementation information to indicate a subsystem configuration of an ATM switch. (30) Communication path configuration Information is output port of switch port for passing messages from processor such as OMP or CCCP in subsystem to processor or matching module SIM, TIM (5, 11) of other subsystem. It is to manage information. Internal communication networks are formed through up to three switches. In FIG. 1, only the output port 6 of the ASNM is required because the CCCP 8 can transmit the message through the switch 7 of the ASNM in order to deliver the message to the SIM. In order to forward messages from CCCP (8) to another CCCP, it is necessary to know the first switch port (9) output from ASNM (7) to ISNM and again to know the second switch port information connected from ASNM to ASNM of ALS on which counterpart CCCP is implemented. And know the third switch port number to which the counterpart CCCP is connected in the ASNM of the counterpart ALS. The management of the switch port number to such a destination is the channel configuration information. (30) When adding or deleting a subsystem, the channel configuration information in the processors of all the currently operating subsystems must be changed.

4 is a flowchart showing the shape addition function of the ATM switch of the present invention.

It starts running with the start of the exchange, repeating indefinitely and waiting for further subsystem requests. When adding a subsystem, it receives the ASNM port number and ISNM port number connecting the ASNM and the ISNM of the ACS subsystem in the newly added subsystem. (31) The requested subsystem is already implemented. If it is a subsystem (32) it is notified that it is not possible to add a subsystem. (33) Then it is notified that if all existing processors are in a normal state (34) it is not possible to add a subsystem (35). If the port is already in use by another processor (36), it is notified that it is not possible to add a subsystem. (37) Subsystem configuration information located in the OMP processor of the ACS (26, 29) if it is possible to proceed with additional installation of the subsystem normally. Change the subsystem configuration information using the new subsystem. (38) Send and receive messages from all processors to the newly added subsystem's processor. In order to be able to do so, a process of changing the channel configuration information 26, 27, 28, and 30 located in all the processors is performed. Assign the ISNM port entered in the switch port and assign the second switch port port 31. (44) This is because the OMP is connected to the ISNM, the ISNM needs to know the ASNM port number of the new subsystem and also the ASNM of the new subsystem. Since the processor is connected to port 31 of, it means that the message can be delivered through port 31 of ASNM. For non-OMP processors, the first switch port is assigned the same port as the first port to OMP, the ISNM port entered for the second switch port, and 31 for the third switch port. It refers to information that a message is transmitted to a processor of a newly added sub-system via port 31 of a new ASNM via ISNM to a new ASNM through a switch port from ASNM to ISNM. When the port allocation is completed, the communication channel configuration information is changed using the new subsystem as the destination. (45) The operating system (OS) is notified of the change so that the message can be transmitted and received. (46) Communication for all processors When the change of the information is finished (40), the subsystem addition addition is notified and the procedure for adding the subsystem configuration is finished. (41)

5 is a flowchart of the shape deletion function of the ATM switch of the present invention.

It starts running with the start of the exchange and repeats indefinitely waiting for the subsystem deletion request. Examine whether the requested service system is present in the configuration (48), and if it is an unmounted subsystem, notify of the inability to delete the subsystem. (49) Determine whether the status of all running processors is normal (50). If there is a processor, the sub-system is not deleted. (51) If the switch of the corresponding subsystem is mounted (52), the sub-service is requested to be deleted while the service is in progress to prevent the loss of the service. (53) If it is confirmed that the system can be deleted, the subsystem configuration information (26, 29) in the OMP of the ACS is changed and the subsystem configuration information is changed. (54) A procedure of changing communication channel configuration information on all processors is performed. (55) A corresponding sub in communication channel configuration information of all processors is performed. (58) When the deletion of the information is completed, the operating system (OS) is notified that the communication channel information has been deleted. (59) Changing the communication channel information in all processors. When the process is terminated (56), it is notified that the deletion of the subsystem is completed, and the deletion procedure is terminated. (57)

As described above, the present invention is based on a system connection and a switch connection configuration, in which a switch for ATM exchange is distributed around a central switch (ISNM) and a distributed system in which a processor is mounted to control an exchange function based on each switch. It is configured by. The distributed distributed subsystem shape information is maintained in the OMP, which is a processor, and communication path information for communication of messages in the exchange is located in the CCCP of each distributed subsystem. Communication between subsystems uses switches in the exchange. Thus, each subsystem shape has a hierarchical relationship with communication path information of a lower layer subsystem. This hierarchical and functional relationship should be maintained when adding and deleting shapes, and according to this relationship, methods and principles for configuring configuration management functions such as adding and deleting resource shapes are established.

Through the present invention as described above, the method of resource management for each subsystem configuration constituting the exchange is secured, and the mismatch of communication information between each subsystems that may cause loss due to interruption of service when the configuration is reconfigured. Prevents and provides flexibility and convenience in reconstruction of the shape.
