Charging Data Processing Method of Optical Creative Maintenance System Using Shared Memory

摘要

The present invention relates to a charging data processing method of an optical CATV maintenance system using a shared memory. When the charging management processor 17 receives a charging data block from the LAN communication processor 16, the central station 2 and the distribution center are provided. A first step of storing the node number and serial number and the number of billing data blocks for which the unique number of (3) is known; and comparing the stored contents with the serial numbers recorded in the shared memory and matching The second step of requesting retransmission to the distribution center 3 by processing a negative response (NAK) together with the corresponding serial number if the charging data block does not match, and if there is no error after verifying the charging data block, subscriber charging A third step of generating a DB to process an ACK and recording the next serial number in a shared memory; The fourth step is to create an abnormal billing DB and record the next serial number in the shared memory, which may occur during transmission in collecting and storing billing data from the billing system included in the optical CATV system maintenance system. It is possible to minimize the loss of billing data that can be, and to increase the stability and reliability in the storage of billing data.
