Method for implementing on-line charging of control business stream and network system thereof

Abstract

The invention discloses a realization method for controlling the on-line charging of service flows, and a network system thereof. Service ending conditions are set in the local site by general packet radio system gateway support nodes; when detecting that the service meets the service ending conditions, the general packet radio system gateway support nodes report a credit control request message and a service ending message to a real-time on-line charging system; the real-time on-line charging system ends the service according to the received credit control request message and the service ending message. By adopting the realization method for presetting the service ending conditions in the local site, the information quantity carried by CCR is reduced in the flow, thus reducing the interaction of the on-line credit control messages between GGSN and OCS, and the load of the OCS and the GGSN for processing the on-line charging, and improving the message interaction efficiency between the GGSN and the OCS, and the accuracy of system charging.

Description

technical field [0001] The invention relates to an online charging control method and system based on service flow in a packet domain in a mobile communication system, in particular to an implementation method and a network system for controlling service flow online charging. Background technique [0002] SGSN (Serving GPRS Support Node: General Wireless Packet System Service Support Node) is the processing center of packet services, and supports the access of BSC (Base Station Controller: Base Station Controller) and RNC (Radio Network Control: Radio Network Controller). SGSN directly serves mobile users, providing mobile users with mobility management, PDP (Packet Data Protocol: Packet Data Protocol) context processing and other PS (Packet Switched: Packet Switched) type services. SGSN stores PS domain user information The relevant location and subscription information is a dynamic database, and these data are necessary for processing initial or passive packet data transmi...

Problems solved by technology

According to the above interaction process, the online credit control process of this service exists all the time from the time when the user activates the PDP to start using a certain service until the user deactivates the PDP; A certain service is used for a period of time. For example, the user uses service 1 for a certain period of time, but the subsequent user no longer uses service 1 but uses other services. At this time, since the PDP is not deactivated, the online credit of service 1 The control is not over, which leads to the online credit control interaction between GGSN and OCS about service 1, but this interaction is actually invalid, which greatly wastes the processing performance of OCS and GGSN, and increases the system load
