Abstract: This invention proposes a method of applying multi-threaded framework on online charging network service. Web service process launches listening socket in the service end to wait for connection in the customer end. When the listening socket intercepts connections in the new customer end, the web service process in the service end derives a positive thread, which reads positive data out of the socket and a negative thread, which sends the data to the socket. This invention can ensure that both the positive and negative data in the network interface at any time will be treated on time to fully reduce data transmission delay in the network interface.

Abstract: An application method of On-line Charging System in Arrears Risk Control System: 1) The subsystem of OCS, Mediation, communicates with CC Client, receives a credit control request raised by the CC Client and processes with a fault-tolerant management. 2) The Credit Control analyses call request, identifies a type of service and request, selects necessary service transaction logic, and judges an authorized quota of the service, after receiving the quota, the Credit Control requests for real time forward modeling from the Rating. 3) After receiving a price of the service, the Credit Control requests real time inversion from the Rating and meanwhile transfers the price to the Rating. 4) The Rating requests account comparison from the Account after receiving the price. 5) The Account compares the price with a customer's account information to make decision of subsistence lock, if there is enough balance in the account, then the fee of the price will be deducted from the balance and then locked.
