Title: Charging file management method by using multi-link in a exchange
Inventor: SON GI SEOK
IPC: H04M15/00
Filed: 2000-06-28
Abstract: PURPOSE: A billing file managing method using a multi-link in an exchange is provided to reduce a billing file transmission load between an exchange and a billing center and thus improve a performance of the exchange by transmitting a generated billing file to the billing center by using an unoccupied link while managing the state of a multi-link accommodated in a built-in external matching block. CONSTITUTION: A billing file is generated according to a call communication and stored in a billing disk(200). A transmission link manager checks whether a link is released or mounted(201). In case of link release, the transmission link manager stores a message indicating the state of a multi-link is abnormal, In case of the link mounting, the transmission link manager stores a message indicating that the state of the multi-link is normal(203). An operator registers a billing period and a billing file deletion time in an OS(204). The OS transmits a period signal according to the corresponding billing period to a billing file generating and processing unit(205). The billing file generating and processing unit inquires a transmission controller as to whether there is a link for transmitting the current file(207). The transmission controller transmits the link state result to a billing file generating and processing unit(208). The billing file generating and processing unit checks whether there is a billing file in a standby state(209). If there is a billing file in a standby state, the billing file generating and processing unit transmits the billing file with a less file sequence number to the transmission controller(210). If there is no billing file in a standby state, the billing file generating and processing unit transmits the currently generated billing file to the transmission controller(211). The transmission controller obtains an unoccupied link and generates a file transmission processing unit(212), receives the generated billing file and stores it in a memory(213). The file transmission processing unit determines whether a transmission-target billing file is to be transmitted or not to a protocol processor(214). If the billing file is to be transmitted, the file transmission processor stores a record that a corresponding link has been occupied in a transmission link(215).
