Abstract

PURPOSE: A charging data generating method of WLL(Wireless Local Loop) is provided to charge a subscriber with a graded fee according to a call distance and collect an accurate usage fee by grouping a base station from which service is provided to subscribers close to WLL by regions and applying a charging rage in a group or between groups and generating a charge. CONSTITUTION: An OCP(Operation Control Processor) of a base station controller generates a group table on the basis of received group information(S10). Charging information tables by groups are generated on the basis of charging information of each group received from an operator of WLL(S12). When an originating/termination call attempt is requested from the subscriber of the WLL, a call processor of an ASP(Access Switching Processor) generates a call processing process to handle the corresponding call, receives a WNC(WLL Network Code) and base station information from a CCP(Call Control Processor), and stores them(S14,S16,S18). A name of a group to which the call originating subscriber and the termination subscriber belong is searched from the group table on the basis of the WNC and the base station information and stored in the certain memory region(S20). It is judged whether the call originating subscriber and the call destination subscriber belong to the same base station controller(S22). A search key for searching a charging information management table by call originating groups is obtained from a prefix information management table(S24). A charging band is obtained from the charging information management table by call originating groups(S26). A charging rate to be applied to the corresponding charging band is obtained from the charging rate management table(S28). The searched charging rate is stored, a call is normally connected as the call termination subscriber answers to the call requested by the call originating subscriber, and when the call is normally released according to a request, the total call time is calculated(S30,S32,S34,S36). The searched charging rate is applied to calculate a charging level and charging data are generated on the basis of the calculated charging level(S38).

Description

Charging Data Production Method of WLL}

The present invention relates to a method of generating billing data of a wireless subscriber network, and in particular, a group of base stations receiving a service from a local unit in a short distance from a wireless subscriber network is grouped to apply billing data differently within a group and between groups.

Conventionally, the distance between a base station to which a called party is served, That is, since the billing data is generated by applying a billing rate that is constantly set based on the total talk time regardless of the distance between call regions, there is a problem in that the subscriber cannot be charged a differential fee according to the talk distance.

The present invention has been made to solve the above-mentioned problems, and the subscribers of the local unit in the short distance from the WLL group the base stations receiving the service so that the billing rate can be generated by differently applying intra-group and inter-group charging rates. It is an object of the present invention to provide a method for generating charging data of a wireless subscriber network.
