METHOD, SYSTEM, CHARGING EQUIPMENT, AND ACCOUNT BALANCE MANAGEMENT CENTER FOR FREE RESOURCES PROCESSING

摘要

Embodiments of the present invention provide a method, an apparatus, and a system for improving a service success rate. The method includes: receiving a credit control request sent by a front-end device, where the credit control request includes a service unit that is applied for and a user identifier; determining, according to the user identifier, that the current request meets a free resource processing condition, and generating a free resource account item; performing rating processing on the service it that is applied for and generating a cash account item; and sending a credit control request carrying the cash account item and the free resource account item to an account balance management center, so that the account balance management center performs cost accounting according to the cash account item; and the free resource account item. When the balance of a free resource account book is 0, a cash account book is directly used for cost accounting, without requiring the ABM to send a message to an OCS again, thereby decreasing message interactions between the OCS and the ABM, reducing ratings of the OCS, and improving charging efficiency.
