Method and system for achieving charging in interactive voice response service

Abstract

The invention discloses a method and a system for achieving charging in interactive voice response service. The method comprises the following steps: receiving a user-initiated trigger message initiated by a service control point through a service exchange point, and transmitting an authentication instruction to an online charging system; and authenticating the user and checking the telephone fee information by the online charging system in real time according to the authentication instruction, and deducting the fee according to conversation time returned by the service control point at the end of the conversation. Compared with the prior art, the method can achieve accurate charging of IVR service according to time by authenticating the user and checking the telephone fee information and deducting the fee in real time according to conversation time returned by the service control point at the end of the conversation, thereby overcoming the disadvantages of the conventional IVR message rate charging to save the user's expense, and solving the problem of excessive occupation of telephone channel resources in the free IVR service to fully utilize the local network resource.

Description

technical field [0001] The present invention relates to the field of telecommunication industry, in particular to a method and system for realizing charging in interactive voice response service. Background technique [0002] At present, the IVR (Interactive Voice Response, Interactive Voice Response) business under the OCS (Online Charging System, Online Charging System) mode provides users with a series of individual services such as checking balance, recharging, checking family number, and transferring money. For the charging issue of users using the IVR service, for services using the traditional IVR service charging mode, see the signaling process in figure 1 As shown, the description is as follows: [0003] 101. The user initiates a call, MSC (Mobile Switch Center, mobile switching center) triggers the service according to O_CSI (Originating CAMEL Subscription Information, originating CAMEL subscription information), SCP (Service Control Point, service control point) ...

Problems solved by technology

[0012] However, none of the above methods can accurately reflect the charging based on the time users use network resources, which lacks scientific

Pay-per-use billing wastes user expenses; users use IVR services for free, causing users to occupy too many session resources, which cannot effectively control IVR service processes that occupy too many session resources, and are not conducive to operators to make full use of network resources. For example, free USSD (Unstructured Supplementary Service Data, unstructured supplementary data) business
