Method and system for making statistics of media flow information in a next generation network
First Claim
1. A method for making statistics of media flow information in a Next Generation Network (NGN), comprising:
- receiving, by a Policy Decision Function (PDF), a request for making statistics of media flow information of a media flow with an identifier of the media flow and a resource reservation request from an Application Function (AF) in the NGN, wherein the NGN comprises a service layer with a core of an Internet Protocol Multimedia Subsystem (IMS) and an Internet Protocol (IP) based transport layer, wherein the resource reservation request comprises metering requirements of metering the media flow and reporting the statistic information;
sending, by the PDF, the request for making statistics of the media flow information to a Border Gateway Function (BGF) if the resource reservation request passes an admission rule;
receiving, by the PDF, statistic information of the media flow in the NGN from the BGF, wherein the statistic information of the media flow is metered by the BGF after receiving the request for making statistics of media flow information; and
sending, by the PDF, the statistic information of the media flow to the AF.

Abstract
A method for making statistics of media flow information may include: sending a request for making statistics of media flow information to a BGF; and receiving statistic information of the media flow from the BGF, wherein the statistic information of the media flow is metered by the BGF after receiving the request for making statistics of media flow information A system and a BGF are also disclosed in embodiments of the present invention. In the present invention, the accurate metering ability of the BGF is employed to acquire accurate statistic information of the media flow, thereby accurate service charging may be implemented and service charging based on used network resources amount and QoS may be supported. Furthermore, the statistic information of the media flow, such as start time, end time, flow count information and statistic information of actual QoS, may help operation and maintenance of the network.
