Abstract
The invention provides a system and a method for a service identification and management system to obtain information. The method comprises the step as follows: the service identification and management system DPIF (deep packet inspection function) obtains information required for customizing strategy rules from a resource acceptance control function (RACF). When the technical scheme is adopted, the information required for customizing the strategy rules comprises user subscription information and/or resource availability information. Relevant information required for customizing the strategy rules like the user subscription information and/or resource availability information is directly obtained by the DPIF from the RACF; therefore, the strategy rules customized by the DPIF are more delicate.
Description
Technical field
The present invention relates to the communications field, and especially, relate to the system and method that a kind of traffic identification and management system are obtained information.
Background technology
At present, next generation network (Network Generation Network, abbreviate NGN as) be a hot research problem in current communication standard field, it adopts the IP group technology as Bearer Network, and converged fixed communication and mobile communication, thereby NGN can provide abundanter multimedia service, for example, emerging service (Internet Protocol Television with real-time requirement, video conference, the multimedia remote teaching, video request program etc.), these business need communication networks can provide efficiently the support of service quality (Qualityof Service abbreviates QoS as) end to end; Simultaneously because the user is also more and more higher to the requirement of network service quality.Therefore, providing end to end, QoS is one of key problem of NGN.
(the International TelecommunicationUnion-Telecommunications standardization sector of standardization department of international telecommunication union telecommunication, abbreviate ITU-T as) be (the International Telecommunication Union of International Telecommunications Union, abbreviate ITU as) telecommunications department, formulated the standard of relevant resource and admission control.Up-to-date resource accommodating control function (Resource and Admission Control Functions in the ITU-T announcement, abbreviate RACF as) in the draft, the functional framework of RACF is provided, as shown in Figure 1, RACF is made up of two parts, be respectively policy deciding functional entity (Policy Decision Functional Entity, abbreviate PD-FE as) and transfer resource controlled function entity (Transport Resource Control Functional Entity, TRC-FE), wherein, TRC-FE is mutual by Rc and transfer function, carry out functional entity (Transport Resource Enforcement Functional Entity by Rn and transfer resource, abbreviate TRE-FE as) mutual, and, PD-FE is mutual by Rt and TRC-FE, by Rh and the local network of users (CustomerPremises Network, abbreviate CPN as) mutual, by Rw and policy execution functional entity (PolicyEnforcement Functional Entity, abbreviate PE-FE as) mutual, service control function (Service Control Functions by Rs and operation layer, abbreviate SCF as) mutual, by Ru and network attachment controlled function (Network Attachment Control Functions, abbreviate NACF as) mutual, and PD-FE is mutual by Ri interface and other next generation networks.
In addition, PD-FE and transmission technology are irrelevant, and be also irrelevant with SCF, the business information that PD-FE policing rule Network Based, SCF provide, the transport layer CAMEL-Subscription-Information that NACF provides, and the Resource Availability result of decision that provides of TRC-FE, make the last decision-making of resource and admission control.
TRC-FE and independent of service, but relevant with transmission technology.TRC-FE is responsible for collecting and safeguarding transmission network information and resource state information.After receiving resource request from PD-FE, TRC-FE carries out resource-based admittance and controls based on QoS, priority demand, Resource Availability information and the policing rule relevant with transmission.
Transport layer is by policy execution functional entity (Policy Enforcement Functional Entity, abbreviate PE-FE as) and transfer resource execution functional entity (Transport Resource EnforcementFunctional Entity abbreviates TRE-FE as) composition.PE-FE carries out the policing rule that PD-FE issues, PE-FE wraps packet gateway, can be positioned at the local network of users (Customer Premises Network, abbreviate CPN as) and access network between, between Access Network and the core net or between the different operators network, it is the key node of supporting that dynamic QoS control, port address conversion and control and network address translation (NetworkAddress Translator abbreviates NAT as) are passed through.TRE-FE carries out the transfer resource policing rule that TRC-FE issues, and its scope and function and Rn interface remain further research, not in the research range in R2 stage.
Traffic identification and management system (Deep Packet Inspection Function, DPIF) possess abilities such as User Recognition, traffic identification, the identification of QoS mark, content recognition, can realize carrying out traffic management and tactical management based on information such as user terminal identification information, IP address, types of service.As shown in Figure 2,, DD-FE (DPI Decision-Functional Entity, traffic identification and administrative decision functional entity) is arranged, information and executing management strategy and the qos policy collected according to DD-FE at transmission control layer at DPIF; In transport layer, DE-FE (DPI Enforcement-Functional Entity, traffic identification is carried out functional entity with management) is arranged, carry out the policing rule that DD-FE issues.
At present, RACF does not support mutual with DPIF, only considers local characteristic information when DPIF generates strategy rule, and therefore the policing rule of formulating can't be realized the becoming more meticulous of Internet resources, intelligent control.
Summary of the invention
