By the present invention, the problem that the network resource management efficiency of traditional charge is relatively low is solved, so as to reach the effect that the network resource management efficiency is improved by dynamically controlling the charge according to a strategy control mechanism.
Description
Technical field
The present invention relates to the communications field, in particular to method, Apparatus and system that a kind of charging controls.
Background technology
Code division multiple access access 2000 (Code Division Multiple Access 2000, referred to as CDMA2000) network can use simple the Internet protocol (Simple InternetProtocol, referred to as simple IP), mobile Internet Protocol (Mobile Internet Protocol, referred to as MIP) or proxy mobile internet protocol (Proxy Mobile Internet Protocol, referred to as PMIP) as its network communication protocol.
Fig. 1 is the CDMA2000 network reference model adopting simple IP agreement, wherein, Radio Access Network (Radio Access Network, referred to as RAN) comprise Packet Control Function (Packet Control Function, referred to as PCF) and wireless heterogeneous networks (Radio Resource Control, referred to as RRC); The circuit switched part of core network is responsible for the realization of voiceband user calling, it comprises mobile switching centre (Mobile SwitchingCenter, referred to as MSC) and attaching position register (Home Location Register, referred to as HLR); Support that the core network packet switched portion of Packet data service is responsible for the realization of user data service, it comprises packet data service network (Packet Date ServiceNetwork, referred to as PDSN) and authentication and authorization charging (Authentication, Authorization and Accounting, referred to as AAA).Simple IP network can only support calling service, i.e. the business of terminal active initiation, as web page browsing, Email etc.If the business that network is initiatively initiated, then must use mobile IP technology or proxy-mobile IP technology.
Fig. 2 is the CDMA2000 reference model adopting MIP agreement, compared with the simple IP network reference model shown in Fig. 1, the reference model of mobile IP network has increased Foreign Agent (Foreign Agent newly, referred to as FA) and home agent (Home Agent, referred to as HA) functional network element.Wherein, FA is positioned at local network, can be terminal distribution Care-of Address (Care of Address, referred to as CoA), for terminal provides local access, simultaneously for terminal completes the MIP registration between HA, between FA and HA, or set up MIP tunnel between terminal and HA, in CMDA2000 network, the function of FA can be integrated in PDSN.HA is positioned at home network, for the positional information of maintenance terminal, is terminal distribution home IP address, and the MIP registration request of response terminal, safeguard the mapping of CoA and home address (Home Address, referred to as HoA).Terminal is occurring (namely to occur to switch across PDSN) in access handoff procedure to adopt the network of MIP technology to ensure, the business of carrying out can not be interrupted, and ensures the continuity of business, the business of network enabled initiation simultaneously.
CDMA2000 network of network reference model and Fig. 2 of employing PMIP agreement are similar.Wherein FA and HA is moved IAD (Mobile Access Gateway, referred to as MAG) and the mobile grappling in this locality (Localized Mobility Anchor, referred to as LMA) functional network element replaced respectively.The position of LMA network element is equivalent to HA, is also to be responsible for terminal distribution home IP address, simultaneously in the PMIP registration process of terminal, is responsible for the binding relationship safeguarding CoA and HoA.MAG function is mainly terminal and provides local access, and in PMIP network, MAG function can be integrated in PDSN.The difference of PMIP network and MIP network is, CoA in MIP network can distribute to terminal also can distribute to PDSN difference, and the CoA in PMIP network can only distribute to PDSN, and terminal only needs HoA just can commence business, namely, under PMIP network, terminal does not need perception oneself whether to there occurs switching across PDSN.
For CDMA2000 network, if terminal is commenced business, first need to set up PPP session between PDSN.If the success of PPP session establishment, then between terminal and PDSN, establish main service connect.This service connects and is mainly used in command transmitting control flow check, also can be used for transmitting needs and to do one's best the business data flow of (best effort) mode.In addition, in order to meet the service implementation differentiate quality of services of carrying out (Quality of Service, referred to as QoS) needs that ensure, multiple assistant service can also be set up connect between terminal and PDSN, there is in order to carrying the business data flow of different QoS requirements.
CDMA2000 net definitions is by PDSN collecting charging information, and and the mutual charging implementation of AAA.Its accounting control process is as follows: the IP stream connected for main service realizes based on serving the charging connected.After main service connection establishment is successful, the charge information based on service connection of collection is sent to AAA by PDSN, starts charging process, and equally when main service Connection Release, PDSN needs and AAA alternately, stop charging process.And the IP stream connected for assistant service can realize based on service connection or the charging based on IP stream.After the success of assistant service connection establishment or when activating at business data flow, by PDSN collecting charging information, and send to AAA, start the charging process relevant with business.Stop after business data flow stops or after assistant service Connection Release, stop charging process.Its control mode depends on the strategy that operator configures on PDSN.
Along with the increase of networking user, and the business that network is carried out is more and more abundanter, is just becoming be becoming tight day for transmitting the Internet resources providing QoS to ensure for business.Tradition by pre-configured wait extensive style resource management mode can not meet operation demand, in order to improve resources management efficiency, need to introduce dynamic strategy controlling mechanism in a network, it can according to the business development situation on network, real-time distribution or releasing network resources, and realize charging flexibly.Third generation partner program (3rd Generation Partnership Project, referred to as 3GPP) define strategy for mobile network and charging control architecture (Policyand Charging Control, referred to as PCC), comprise: "Policy and Charging Rules Function (Policy and Charging Rules Function, referred to as PCRF), strategy and charge execution function (Policy and Charging Enforcement Function, referred to as PCEF), bearing binding and reporting events function (Bearer Binding and Event ReportFunction, referred to as BBERF) and user-subscribed database (Subscription ProfileRepository, referred to as SPR).Wherein, PCRF can use Internet resources to work out real-time control and charging policy to business according to information such as dynamic service information, user signing contract information (such as obtaining from SPR), carrier policy.PCEF and BBERF is used for the QoS control strategy that real-time execution PCRF issues, Internet resources are used to carry out real-time distribution and release to business data flow, what the PCEF charging policy that also will issue according to PCRF was real-time in addition carries out charging control to business data flow, complete and Online Charging System (OnlineCharging System, referred to as OCS) or mutual about charge information of off-line accounting system (Offline ChargingSystem, referred to as OFCS).
Dynamic strategy controlling mechanism defines dynamic QoS resource way to manage, and by PCEF (being integrated in PDSN or HA or LMA) and OCS or OFCS mutual based on stream dynamic charging way.Operator wishes that network introduces dynamic strategy controlling mechanism, improves network resource management efficiency by it on the one hand, and consider investment reduction cost on the other hand, operator also wishes to utilize original charge system and charging way.Therefore consider the demand, the CDMA2000 network introduced after dynamic strategy controlling mechanism also needs to increase the control realization support to traditional AAA charging way.
For the problem that charging way network resource management efficiency comparison traditional in correlation technique is low, at present effective solution is not yet proposed.
