Flow accounting method and packet data service node

Abstract

The invention discloses a flow accounting method and a packet data service node. The flow accounting method comprises the following steps of: carrying out QOS (Quality Of Service) negotiation by a terminal and the packet data service node; identifying whether an IP (Internet Protocol) packet flowing through the packet data service node is a QOS negotiation signaling or not by a signaling identification; if so, counting the IP packet as a QOS negotiation flow; otherwise, counting the IP packet as a user actual flow; and sending the user actual flow to an AAA (Authentication, Authorization, Accounting) server to account according to the user actual flow. According to the flow accounting method disclosed by the invention, the signaling flow of the QOS negotiation signaling can be effectively identified by identifying the QOS negotiation signaling through the signaling identification. The part of the flow can be deducted in the accounting process so that the accurate accounting of the network is realized. Not only is the reputation of service suppliers remained, but also the benefits of users are protected.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular, to a traffic charging method and a packet data service node. Background technique [0002] IP is the technical basis of the Internet network layer protocol. It has a simple structure, is easy to interconnect heterogeneous networks, and has strong network scalability. It can run on any high-level data link and has an extremely wide range of applications. The IP protocol occupies a dominant position in data business procedures and becomes the core of various services. Therefore, major standard organizations have determined the evolution plan of AIPN (All IP Network), 3GPP wireless side introduced HSPA (High Speed ​​Packet Access), HSPA+ (High Speed ​​Packet Access+), LTE (Long Term Evolution), 3GPP2 has already completed EV - Standardization and commercialization of DO (Evolution-Data Only). In short, the development of IP has become an inevitable trend, and there will...

Problems solved by technology

Therefore, the terminal after starting up will have a series of signalings interacting with the network, and the current interactive signaling between the terminal and the packet data serving node (Packet Data Serving Node, PDSN) for QOS negotiation, that is, the RSVP reservation signaling, is also calculated as Although the user's service flow is relatively small, it is also unreasonable to charge, especially when a terminal with QOS service arrives at a wireless network that does not have QOS service enabled, since the terminal does not know the actual situation of the network, the number of times of negotiation may There will be more, and the signaling traffic generated by the negotiation will also be more, so the above-mentioned unreasonable and inaccurate billing problems are imminent and must be resolved
