Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a telephone exchange system billing processing method,
Especially in telephone exchange systems where billing information is sent from a system other than the own exchange,
In order to prevent the line from being held undesirably for billing processing and to facilitate program processing, a billing information storage area is prepared independently of the line corresponding storage area, and the line is stored at the stage of call termination. This invention relates to a telephone exchange system billing processing method that allows the corresponding storage area to be released.

Conventionally, in a storage program controlled telephone exchange system, billing information is stored in a line-corresponding storage area prepared for each line, and the billing information is managed based on the line number. This requires information such as the calling subscriber number, called subscriber number, and call time for billing processing, and also detects responses, disconnections, etc. necessary to determine call time using the line number. You can think of it as being based on things you do. However, in a system where billing is based on the above information and transmission information transmitted from another exchange system, the line is held on hold until the transmission information is sent, and the transmission information is transferred to the line. It is necessary to store it in the corresponding storage area. For this reason, the line hold time becomes undesirably long, leading to an increase in equipment. In addition, regarding program processing, call processing, which involves call termination, and billing processing overlap, making the program complicated.

The purpose of the present invention is to solve the above-mentioned problems, and the telephone exchange system billing processing method of the present invention provides information between the exchange that accommodates the calling subscriber and the exchange that accommodates the called subscriber. A telephone exchange system that transmits and receives information, in which information to be collected by the exchange in which the subscriber is accommodated is transmitted from the system including other exchanges connected to the exchange, and billing is performed based on this information. In a telephone exchange system, in response to the call of the calling subscriber, a management number is assigned and sent to the system side, the management number is stored in a storage area corresponding to the line, and a billing information storage area is allocated to the storage area corresponding to the line. An area independent of the storage area is configured to be indexable based on the management number, and information collected in the process of processing the call is used to perform the billing based on the management number stored in the line corresponding area. The system side accesses the billing information storage area based on the management number instructed by the system side after the line corresponding storage area is released when the call ends. The billing information is managed by storing the billing information transmitted from the billing information storage area in the billing information storage area. This will be explained below with reference to the drawings.
