Charging method and system for pre-payment service

Abstract

The invention discloses a charging method and system for pre-payment service, wherein the method includes: under the instance of triggering a first flow path and a second flow path of users at a mobile switching center or a service switching center, successively or simultaneously determining the first flow path amount of the first flow path and the second flow path amount of the second flow path according to the pre-configured call time period, and reserving the first flow path amount and second flow path amount in the total amount of users; when the first flow path and second flow path are finished, deducting amount from the total amount of users according to the use of the users. By the use of the invention, the overdraft problem appearing in the pre-payment forwarding service of the related technology can be effectively solved, and the benefits of operators can be ensured.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a charging method and system for prepaid services. Background technique [0002] In the integrated intelligent network system, the processing of the call flow is as follows: firstly, the mobile switching center (Mobile Switch Center, MSC) / service switching center (Service SwitchPoint, SSP) triggers the call flow on the service control point (Service Control Point, SCP), The call process judges the remaining amount of the user, calculates the duration of the call that the user can allow according to the billing plan and the remaining amount of the call, and sends the Apply Charging (AC) to the user according to the time period set by the system. SSP requests SSP charging control. After the set time period ends, SSP will report the application charging report (Apply Charging Report, ACR) to SCP to report the call duration. SCP accumulates the call duration until the end o...

Problems solved by technology

Each process bills the call duration of each process according to the user's remaining amount, and the SSP monitors the call process. When one process call ends, the user's remaining amount is deducted, and when the other process call ends, at this time The user's balance has changed, and it has become the user's original balance minus the usage amount of the last call process. The user's balance is no longer the cost of the original calculation time. In this way, an overdraft problem will occur when the fee is deducted.

[0004] Aiming at the problem of overdraft that may occur when prepaid users call forward, prepaid users are usually not allowed to have the forwarding function. However, this obviously cannot meet the needs of users for business diversification; another solution This problem is solved free of charge for the called process when the forwarding occurs. However, this obviously cannot satisfy the interests of the operator, and neither of these two solutions can effectively solve the problem of overdraft from the front.

[0005] At present, there is no technical solution that can effectively solve the problem of overdraft for prepaid users when calling forwarded
