Pre-biller capability in enhanced charging collection function (CCF) applications

Abstract

This invention relates to a method and apparatus for charging and billing of Circuit Switch, Packet Switch, and IP Multimedia Subsystems in third generation telecommunication systems. The charges for a call are computed by a rating engine, a software system comprising data tables and a program for calculating charges from the parameters of the call, such as the calling and called numbers, the length of the call, and special charge items such as priority service. For calls whose billing cannot be deferred, referred to as on-line billing calls, the rating engine is accessed immediately. For calls whose billing can be deferred, referred to as off-line billing calls, the rating engine performs its function only when the rating engine is not busy rating on-line billing calls, for example, during periods outside the busy hour. Advantageously, only a single rating engine is required, and the capacity of that single rating engine is determined only by the busy-hour volume of on-line billing calls.

Description

RELATED APPLICATIONS [0001] This application is related to an application of Xiang Yang Li, Min Liu, John B. Reid, Guy H. Starner, Ashish Trivedi, Peng Wang, Yile Enoch Wang, Jun Zheng Yang, Lei Zhang, and Jay Z. Zhao entitled “New Call Authorization And Billing Message Routing Capability”, which application is assigned to the assignee of the present application and is being filed concurrently herewith. TECHNICAL FIELD [0002] This invention relates to a method and apparatus for charging and billing of Circuit Switch, Packet Switch, and IP Multimedia Subsystems. BACKGROUND OF THE INVENTION [0003] This document describes a method and apparatus for enhancing the charge collection function, using third generation telecommunication systems as an example. [0004] The introduction of the third Generation Partnership Project (3GPP) and the third Generation Partnership Project 2 (3GPP2) harmonization effort known as IP (Internet Protocol) Multimedia Sub-system (IMS) has introduced new converg...

Benefits of technology

[0011] Applicants have inventively discovered a method and apparatus for streamlining both the on-line and off-line billing process by utilizing a common charging system, which includes charging, rating, and subscriber balance management functions. The charging system is able to process online calls as an Online Charging System (OCS) as defined by 3GPP and 3GPP2, as well as a charging system for offline calls in real-time or non-real-time. If an offline call requires real-time charging, a call data record is built and a single rating engine built within the OCS is consulted immediately to determine charges on that call; for an offline call requiring only non-real-time billing, the call data record is built without immediately including the charge information and the single rating engine built within the OCS is consulted only when that rating engine is not busy calculating charges for an on-line billing call. As a result, advantageousl...

Problems solved by technology

OCS rates calls with a built-in rating engine and provides charging cost and generates CDRs.

However, there are no standards (neither 3GPP nor 3GPP2) which su...
