A statistic method of the media flow in the next generation netwokr (ngn)

The invention relates to a NGN network media stream statistical method. Method for core is mainly comprises: First equipments, the media stream counting request to border gateway control function BGF by using function, AFThen, BGF plate and media stream information according to the support AF of the counting, and is a media stream information circuit of counting AF. The invention adopts the BGF media stream precise measuring capability, capable of realizing service precise cost, and said network resource are used-based and quality of service charging. Moreover, the invention counting media stream start time, terminal and time current capacity counting information and physical service quality information statistical equal, and is further compressed to the operation and maintenance of network.
