KR930011493A - Subscriber Service by Node-to-Node Database Allocation in Multi-Distributed Node Structure Switching System - Google Patents

Abstract

In the multidistributed node structure switch, a method for improving the memory size of each node due to overlapping database allocation among nodes and increasing the amount of message traffic between nodes for exchanging database information between nodes. to be.

To this end, the common subscriber information database shared by multiple subscribers and the system database used for configuration, maintenance, and operation of the system are commonly duplicated and stored in all node's main control memory, and the information is limited to specific subscribers. The distributed subscriber database is stored in each node's main control memory for each corresponding node, and the subscriber service is performed using the subscriber common information database, the system database, and the subscriber database.

Therefore, it is possible to perform effective call service by realizing the reduction of the communication volume for the information exchange between nodes and the optimization of the database size of the node.

Claims (3)

In a multi-distributed node structure exchanger configured with a plurality of nodes having a certain subscriber size connected by inter-node links in a network structure, the construction, maintenance, and operation of a Gaiza Gongbong information database and system shared and used by multiple subscribers Nodes, characterized in that the system database used for the common redundant storage in the main node memory of all nodes, and to store the subscriber database consisting of information limited to a specific subscriber in the main node memory of each node for each node How to Allocate Databases. In a multi-distributed node structure switch configured with a plurality of nodes having a certain subscriber size connected in a network structure, a subscriber common information database and system shared and used by a plurality of subscribers that are commonly redundantly stored in main node memory of all nodes. If there is a subscriber who has hooked off, the system database is used for configuration, maintenance, and operation, and the subscriber database consists of information specific to specific subscribers distributed and stored for each node in main node memory of each node. A dial box supplying process for supplying dial tone to the calling party after acquiring the necessary information for the service from the subscriber database by the called party's telephone port address which has been hooked off, and the called party's telephone number inputted from the calling party. By the subscriber common information If the called party acquires a number from the database and the called party is a subscriber in the exchange, if the called party is determined to be a pressurizer in another node based on the telephone number routing information in the subscriber common information database by the telephone number digit, link configuration information between nodes Routing process of acquiring the system from the system database, and transmitting the called subscriber occupancy request message to the called node and supplying the ring backtone to the calling party upon receiving the process response message from the called node. Calling subscriber service method by the database allocation between nodes, characterized in that the process consisting of. In a multi-distributed node structure switch configured with a plurality of nodes having a certain subscriber size connected in a network structure, a subscriber common information database and a system shared and used by a plurality of subscribers that are commonly redundantly stored in main node memory of all nodes. The system database used for configuration, maintenance, and operation of the system, and the subscriber database consisting of information specific to the specific subscriber distributed in each node in the main control memory of each node, from the calling node to the node Receiving Subscriber Request Message The called party's screening process in which the called party examines the idle state by acquiring the necessary information from the subscriber database by the telephone port address of the called party included in the received message and reading the work database. And the called party If it is determined that these statuses are in possession of the called subscriber occupancy process of transmitting a successful occupancy message for the called subscriber port as a process response message to the calling node, supplying a ring to the called subscriber, and providing a pass-through service; Is called, a call termination process is sent to the calling node as a negative response message to the calling node and terminates the processing of the called subscriber port. Called subscriber service method by inter-node database allocation. ※ Note: The disclosure is based on the initial application.
