Description
Technical field
The present invention relates to the communications field, in particular to a kind of conversation-based off-line accounting method that is used for next generation network (Next Generation Network abbreviates NGN as).
Background technology
NGN is based on the communication network that grouping transmits, and it can provide voice, data and multimedia integration service, and can guarantee service quality and safety, and it combines various access waies, can make the third party that application is provided easily.At present, the standardization body of a lot of international and regional property is all carrying out the relevant research of NGN, and much the operators of country are also disposing NGN energetically, and along with deepening continuously of research and improving day by day and enhancing of capacity of equipment, the function of NGN will be from strength to strength.
(the International Telecom Union of International Telecommunications Union, abbreviate ITU as) be the main research organization of NGN, the standard of the NGN front page of releasing (Releasel) is mainly supported PSTN (Public Switched Telephone Network at present, PSTN)/ISDN (Integrated Services Digital Network, integrated services digital network) artificial service, multimedia service, PSTN/ISDN analog service.
As shown in Figure 1, the NGN general frame comprises two aspects: service layer and transmission aspect.The transmission aspect transmits controlled function, resource and permission controlled function and the transport layer user attribute database function that comprises network attached device in the controlled function; Service layer comprises service control function, service-user attribute database and application/business support function, and by API (Application Programming Interface, API) access application.
Along with the construction in broadband and carrying out of NGN business, employing is accurately chargeed to business according to the charging means of flow, duration, content etc. and is had higher requirement, and for this reason, NGN is also stepping up to study the charging relevant framework.Present NGN second edition (Release2) has proposed the charging framework based on strategy, as shown in Figure 2, in this framework, introduced resource authorization controlled entity (Resource Admission Control Function, abbreviate RACF as) as the charging policy decision entity, can issue different strategies according to different broadband services and accurately charge.Reference Point C x wherein and Cy also under study for action, related functional entities is described as follows:
Service control function (Service Control Function abbreviates SCF as) is initiated resource request by the Rs reference point to policy deciding functional entity (PD-FE), and can receive related announcement at resource reservation or after discharging;
Policy deciding functional entity (Policy Decision Function Entity abbreviates PD-FE as) is handled QoS (service quality) resource request that receives SCF and Rw reference point reception PE-FE by the Rs reference point;
Policy execution functional entity (Policy Enforcement Function Entity abbreviates PE-FE as) is carried out the strategy of receiving from PD-FE;
Book keeping operation territory (Billing Domain abbreviates BD as) is used for the process user metering data, produces bill;
Account management function (Accounting Management Function abbreviates AMF as) is used to handle the account associative operation, such as querying the balance amount deducted etc.;
Wholesale price function (Rating Function abbreviates RF as) is carried out the wholesale price processing according to business information and qos-related information;
Online charging function (Online Charging Function abbreviates OCF as) is collected charge information in real time, can carry out credit control;
Charging Collection Function (Charging Collection Function abbreviates CCF as) is collected customer charging information, generates charge information record (Charging InformationRecord abbreviates CIR as);
Charging Gateway Functionality (Charging Gateway Function abbreviates CGF as) is used for producing ticket according to the CIR that collects, and the ticket that produces is sent to BD;
Charging Gateway Functionality between net (Inter-Provider Charging Gateway Function abbreviates IP-CGF as) is used for the charging relevant information between the mutual heterogeneous networks provider.
At present, charging way comprises offline charging and online charging, and type of service can be divided into event mode business and conversational service.Offline charging is finished by OFCS, and online charging is finished by OCS.The OFCS related functional entities has CCF, CGF, and the OCS related functional entities has OCF, AMF, RF, CGF; The event mode business is meant that the metering data of generation is disposable, and is irrelevant with duration; And conversational service is meant that the metering data of generation has process and time that direct relation is arranged.
In realizing process of the present invention, the inventor finds not have based on the charging framework of strategy in the prior art standards and norms of conversation-based offline charging, demands urgently formulating and optimizing.
