The present invention relates to a method for controlling a specific route of an all-electronic exchange, and more particularly, to a method for controlling a specific route for controlling a specific route using skip (SKIP).

As the demand for communication grows rapidly, many resources and services in the new network may easily change traffic patterns or create unexpected network problems.

In the conventional electronic switchboard, the overload phenomenon caused by natural disasters, bad conditions of equipment, and busy traffic on holidays is left without management, and the overload phenomenon continues to affect not only the corresponding exchange but also adjacent exchanges. It has affected a lot.

In the electronic switchboard, the skip (SKIP) is used to limit the traffic to a specific route by a certain amount to reduce the overload of the sub-exchange due to traffic congestion by sending to the bypass route of the corresponding route. Its purpose is to provide users with a way to control specific routes that allow them to continue to provide services.

In order to achieve the above object, the present invention provides an Access Switching Subsystem (ASS) for performing a distributed call processing function, an Inter Connection Network Subsystem (INS) for performing a centralized call processing function connected to the ASS, and a connection to the INS. A method for controlling a specific route requiring skip (SKIP) of an electronic switch, which includes a central control subsystem (CCS), which performs centralization of operation and maintenance. And performing a first step of processing when a cancellation request is input, a second step of processing when a skip information output request is input from an operator, and a third step of processing when a relay call is input.

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

1 is a structural diagram of an electron exchanger to which the present invention is applied, 30 is ASS, 31 is INS, 32 is CCS, 33 is NHS, 4 is NMS, 35 is CIS, 36 is NMS, 37 is DBS, and 39 is RCI , 40 represents CCI, 41 represents NMI, and 42 represents NPS.

The electronic switch to which the present invention is applied has three subsystems of an access switching subsystem (ASS) 30, an interconnection subsystem 31, and a central control subsystem 32, as shown in FIG. It consists of. The ASS 30 performs the distributed call processing function, and the INS 31 performs the centralized call processing function part, thereby performing the centralization function of operation and maintenance in the CCS 32.

In order to provide a method for controlling a specific route to skip (SKIP), there is an NMS 34 in the CCS 32 which is a software subsystem responsible for this function. Network Management Subsystem (NMS) 34 is composed of four software blocks RCI 39, CCI 40, NMI 41, and NPS 42 having shared functions for performing network management functions.

The network management interface (NMI) 41 receives a request for skipping a specific route by the user and divides a command input into a block that performs a function of controlling an interface between the NMI 44 and the NMS 34. Perform output formatting on the processed result. The Route Control Interface (RCI) 39 has a processing function for searching, canceling, changing, and storing a skip function requested by an operator. Conde Controe Interface (CCI) 40 and Network Performancs Supervision (NPS) 42 are blocks necessary for code control among network management functions.

The Man Machine Subsystem (MMS) 36 of the CCS 32 provides an interface between the operator and the exchange period, and is a sub-system that is responsible for outputting formatting commands and outputting system messages to the operator terminal.

The Measurement Satistics Subsystem (MSS) 38 of the CCS 32 is a sub-system in which various systems collect and manage measurement statistical data. The Data Base Subsystem (DBS) 37 of the CCS 32 centralizes the management of the database, so that the data retrieval, data change, and data backup required for the safety and reliability of the data required by the application through the Data Manipulation Langage (DML) It is a subsystem that performs data recovery. In the CCS 32, there is a control interworking subsystem (CIS) 35 connected to the NMS 34, the MMS 36, the DBS 37, and the MSS 38.

The NHS (Number Handling Subsystem) 33 system, which performs number translation and relay line control in the INS 31, routes to the bypass route for the actually generated call.

2 is a block diagram and message flow diagram for implementing a skip control function of an electronic switch according to the present invention, where 43 is MMP, 44 is MMI, 45 is OMP, and 46 is NTP.

The NMS, which is in charge of the skip function, maintains maintenance functions such as system maintenance test management and operation management such as network management, billing, statistics, and database management to ensure the centralization, ease, efficiency, and reliability of management and maintenance functions. The MMS (Man Machine Subsystem) 36, located in the Operation and Maintenace Processor (OMP) 45, which is an operation and maintenance processor that implements the functions and performs the functions, is an I / O processor. Is mounted in an MMP (Man Machine Processor) 43. A Number Handling Subsystem (NHS) 33 capable of verifying functionality associated with a call is located in a Number Translation Processor (NTP) 46, which is a number translation processor.

The NMI 41 in the NMS 34 receives a skip function processing request from the operator, undergoes various command analysis, and then makes a processing request to the RCI 39 in the NMS 34. The RCI 39 then verifies the information of the skip function control for that route, i.e., route number, route type, limit rate, green DMA announcement, and the like. Then, the NHS 33 converts the corresponding route number and necessary information into a data type already promised and handed over to the NHS 33. After receiving the response from the NHS 33 for the processing result, it resists the necessary information and sends a processing confirmation message to the NMI 41. The NMI 41 outputs an appropriate message about the performance to the operator. Is over. This shows the registration of the skip function. The function cancellation, information change, and information output request for a route are also implemented in the same flow.

3 is a flowchart of a method for controlling a particular root in accordance with the present invention. When the operator registers, cancels, or changes the routing of the skip function for a specific route (1), the operator converts the data (limit rate, recording announcement) into an easy-to-process form (2). Check whether the requested route number is a valid number (3). Since this function restricts outgoing calls, it checks whether the outgoing call is required for registration (4). Since the number of routes that can be skipped can be limited up to 124, the number of routes required for registration is checked (5). Then, it is checked whether the route required for registration is already registered for the skip function (6). Verify that the value of the limit parameter is meaningful (7). Verification of the limit function of the skip function is 0%, 12.5%, 25%, 37.5%, 50%, 62.5%, 75% in 12.5 percent increments. , One of 87.5% and 100% should be registered.Restriction rate can be registered because it is classified into DR (Direct-Routed) traffic and Alternate-Routed (AR) traffic according to the type of traffic. You cannot register a limit of. Verify the parameters for the announcement announcement for the skip function (8). For the verification of the announcement announcement, the registered value should have one of NCA (No Circuit Available), EA1 (Emergence Announcement1), and EA2 (Emergence Announcement2).

After converting the verified data into a transmission form (9), the request type is retrieved from the operator, and if a skip function registration request is received, a registration request is made (10) a skip function cancellation request is requested (11) a skip function change request If so, it waits after sending the change request message (12).

When a response message is received for each request message (13), the skip processing result is modified and stored in the database (14), the result message requested by the operator is cleaned up (15), and the output of the resultant message is requested ( 16) The function processing for controlling the specific route to skip is terminated (17).

When an output request for a function is received by an operator (18), information is extracted from the database (19) and ordered by the route number (20). The ordered result messages are arranged (21) and the message output request (22) ends.

According to the present invention configured and operated as described above, when a call is generated by the user with the electronic switchboard, the user registers a restriction rate if the route to which the user wants to call is controlled is compared with the route controlled by the skip. By restricting calls and sending them to the bypass route, the centralized overload of a certain route can be prevented before the routing step, thereby preventing the spread of overload in terms of the network as a whole and providing continuous service to subscribers. Furthermore, the domestic electronic switch TDX-10 (registered trademark), which is manufactured based on domestic technology and experience, categorizes the traffic congestion information of each exchange by the degree of congestion and informs the neighboring exchanges and receives the congestion signal from the neighboring exchange. Depending on the amount of time congestion, traffic to the Switch network control to alleviate the congestion status and receive the network status information and performance information request from the centralized network management center so as to control the efficient network traffic from the network standpoint. It is easy to implement the NMC linkage control function to receive and process the received, there is an effect that can provide a variety of new services quickly required.
