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 for a kind of traffic identification and management system obtaining information.
Background technology
At present, next generation network (Network Generation Network, referred to as NGN) be a hot research problem in current communication standard field, it adopts IP group technology as Bearer Network, and merge fixed communication and mobile communication, thereby NGN can provide abundanter multimedia service, for example, there is the emerging service (Internet Protocol Television of requirement of real time, video conference, multimedia remote teaching, video request program etc.), these business need communication networks can provide efficiently service quality (Qualityof Service end to end, referred to as QoS) support, simultaneously because user is also more and more higher to the requirement of network service quality.Therefore, providing QoS is end to end one of key problem of NGN.
(the International TelecommunicationUnion-Telecommunications standardization sector of standardization department of international telecommunication union telecommunication, referred to as ITU-T) be (the International Telecommunication Union of International Telecommunication Union, referred to as ITU) telecommunications department, formulated the standard about resource and admission control.Up-to-date resource accommodating control function (the Resource and Admission Control Functions announcing at ITU-T, referred to as RACF) in draft, the functional framework of RACF is provided, as shown in Figure 1, RACF is made up of two parts, respectively policy deciding functional entity (Policy Decision Functional Entity, referred to as PD-FE) and transfer resource control functional 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, referred to as TRE-FE) mutual, and, PD-FE is mutual by Rt and TRC-FE, by Rh and the local network of users (CustomerPremises Network, referred to as CPN) mutual, by Rw and policy execution functional entity (PolicyEnforcement Functional Entity, referred to as PE-FE) mutual, by service control function (the Service Control Functions of Rs and operation layer, referred to as SCF) mutual, by Ru and network attachment control function (Network Attachment Control Functions, referred to as NACF) mutual, and PD-FE is mutual by Ri interface and other next generation networks.
In addition, PD-FE and transmission technology are irrelevant, 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 to transmission technology.TRC-FE is responsible for collecting and safeguarding transmission network information and resource state information.From PD-FE receives resource request, TRC-FE, based on QoS, priority demand, Resource Availability information and the policing rule relevant to transmission, carries out resource-based receiving control.
Transport layer is by policy execution functional entity (Policy Enforcement Functional Entity, referred to as PE-FE) and transfer resource execution functional entity (Transport Resource EnforcementFunctional Entity, referred to as TRE-FE) composition.PE-FE carries out the policing rule that PD-FE issues, PE-FE is that bag is to packet gateway, can be positioned at the local network of users (Customer Premises Network, referred to as CPN) and access network between, between Access Network and core net or between 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, referred to as NAT) are passed through.TRE-FE carries out the transfer resource policing rule that issues of TRC-FE, and its scope and function and Rn interface need further research, not in the research range in R2 stage.
Traffic identification and management system (Deep Packet Inspection Function, DPIF) possess the abilities such as user's identification, traffic identification, the identification of QoS mark, content recognition, can realize based on information such as user terminal identification information, IP address, types of service and carry out traffic management and tactical management.As shown in Figure 2, for DPIF, there are DD-FE (DPI Decision-Functional Entity, traffic identification and administrative decision functional entity), information and executing management strategy and the qos policy collected according to DD-FE at transmission control layer; In transport layer, there is DE-FE (DPI Enforcement-Functional Entity, traffic identification is carried out functional entity with management), 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 the policing rule of therefore formulating cannot be realized the becoming more meticulous of Internet resources, intelligent control.
Summary of the invention
