Description
Technical field
The present invention relates to the communications field, be specifically related to implementation strategy and charging control system and method in a kind of CDMA (Code Division MultipleAccess, code division multiple access) system.
Background technology
Third generation partner program 2 (3GPP2,3rd Generation Partnership Project2) Ding Yi CDMA2000 1x and HRPD (High Rate Packet Data, High Rate Packet Data) network architecture, mainly by MS/AT (Mobile Station/Access Terminal, portable terminal/access terminal equipment), RAN (Radio Access Network, Radio Access Network), PDSN (Packet DataServing Node, packet data serving node), HA/LMA (Home Agent/Local MobilityAnchor, home agent/local mobile anchor), AAA (Authentication, Authorization, Accounting, authentication and authorization charging) server and other core network devices and support node composition.As shown in Figure 1, provided 1x and HRPD PDS (Packet Data Service, Packet data service) subnetwork reference model:
MS/AT realizes being connected by wave point with RAN.PDSN is by being provided to the access of other network elements of exterior I nternet or core net (HA/LMA) for subscriber terminal equipment.Its effect is to set up, safeguard PPP (Point to Point Protocol, the peer-peer protocol) session between MS/AT and the PDSN; Accept and carry out the authentication of aaa server to MS/AT; Route from packet that mails to other network elements of packet data network or core net (HA/LMA) etc.
HA (Home Agent, ownership/home agent) is responsible under MIP (Mobile IP, the mobile IP) scene, is terminal distribution home address, the tunnel encapsulation of transmitting packet, packet, charging etc.
AAA (being called RADIUS again) server is an authentication and authorization charging server, and it mainly acts on is which user of management can accesses network, and which service the user with access right can obtain, and how the user who uses Internet resources is chargeed.
All the other network nodes and relation of the present invention are little, here do not introduce one by one.
Third generation partner program (3GPP, 3rd Generation Partnership Project) defined (Evolved Packet System at EPS, the grouping system of evolution) strategy of network and charging control architecture (PCC, Policy and Charging Control), as shown in Figure 2.PCRF (Policyand Charging Rules Function wherein, strategy and charging rule decision entity) be responsible for being used for the network QoS (service quality) of business data flow use and the formulation of the PCC rule that is used to charge, and pass through the Gx interface and give PCEF (Policy and Charging Enforcement Function, strategy and charging execution function entity) the PCC rule downloading; PCEF installs and also to carry out the PCC rule, carry out dependent event and report, and with the mutual charge information of charge system.PCRF also (comprises Gxa by Gxx, Gxb, Gxc) interface will be used for business data flow is carried out the QoS rule downloading of QoS control to BBERF (Bearer Binding and Event Report Function, bearing binding and reporting events entity), BBERF is responsible for bearing binding and relevant bearer reporting events.Other some network elements provide business information by Rx interface to PCRF as AF (Application Function, business function entity).
