Description
Technical field
The present invention relates to the communications field, relate more specifically to Synergistic method and system between a kind of resource controlling platform.
Background technology
NGN (Network Generation Network, next generation network) is a hot research problem in current communication standard field, and it adopts grouping technology such as IP as communication of Bearer Network converged fixed and mobile communication.NGN can provide abundanter multimedia service, as has an emerging service (as VoIP, video conference, multimedia remote teaching, video request program etc.) of real-time requirement, these business need communication networks can provide efficiently service quality (Quality of Service, QoS) support end to end; The user is also more and more higher to the requirement of network service quality simultaneously.Therefore, how providing end to end, QoS will be one of key problem of NGN.
ITU-T is the tissue of the relevant international standard of ITU (International Telegraph Union, International Telecommunications Union) management special formulation telecommunication down, is called telecommunication standard office of international electronics alliance, has formulated the standard that relevant resource and admission is controlled.In the up-to-date draft of the RACF (Resource and Admission Control Functions, resource accommodating control function) that ITU-T announced in January, 2008, provide the functional framework of RACF, as shown in Figure 1.RACF is made up of two parts: policy deciding functional entity (Policy Decision Functional Entity, PD-FE) and transfer resource controlled function entity (Transport Resource Control Functional Entity, TRC-FE).
PD-FE and transmission technology are irrelevant, its policing rule Network Based, AF (Application Function, application function) business information that provides, network attachment controlled function (Network Attachment ControlFunctions, NACF) the transport layer CAMEL-Subscription-Information that provides, and the resource and admission result of decision that provides of TRC-FE, make the last decision-making of network resource admission control; PD-FE carries out gate control based on each stream to PE-FE, based on professional usage policy rule.
TRC-FE and independent of service, but relevant with transmission technology.TRC-FE is responsible for collecting and safeguarding the topological sum resource state information of transmission network, availability based on topology, connectivity, network and node resource, and, transmission network carried out admit control based on the use of the network informations such as transport layer CAMEL-Subscription-Information in Access Network control resource.PD-FE is by the QoS resource on the media stream path that Rt interface requests TRC-FE detects or decision is asked.
(Policy Enforcement Functional Entity, (Transport Resource Enforcement FunctionalEntity TRE-FE) forms transport layer PE-FE) to carry out functional entity with transfer resource by policy execution functional entity.PE-FE wraps packet gateway, can be positioned at subscriber terminal equipment (Customer Premises Equipment, CPE) and between the access network, 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 NAT (Network Address Translator, network address translation) pass through.TRE-FE carries out the transfer resource policing rule of TRC-FE indication, and its scope and function and Rn interface remain further to be studied.
●PD-FE
PD-FE is a policy deciding functional entity, it makes preliminary QoS resource decision based on medium streaming session information (obtaining from AF by the Rs interface), user's transfer resource CAMEL-Subscription-Information (obtaining from NACF by the Ru interface), with affirmation whether enough QoS resources are arranged alternately with TRC-FE then, make a final decision at last, and this decision-making is handed down to the PE-FE execution.
●TRC-FE
TRC-FE mainly is responsible for resource control, and the resource in its monitor network is also collected relevant information, replys according to concrete resource situation when the PD-FE request resource.
●PE-FE
PE-FE carries out policy control (gate, bandwidth, traffic classification and mark, traffic shaping, two layers and three layers of QoS mapping, collection and report resource use information etc.) under guidance at PD-FE.
●TRE-FE
The present explanation of TRE-FE agreement is to carry out two layers strategy execution under TRC-FE instructs, and is definite but concrete function and scope all not have.
3GPP (The 3rd Generation Partnership Project, third generation partner program) then inserts angle from moving, in up-to-date 3GPP R7 draft, (the Policy Decision Function of the strategy decisive function in the R6 version, PDF) and based on the billing function that flows (Flow BasedCharging FBC) merges, and has proposed PCC (Policy Control and Charging, policy control and charging), finish resource accommodating control function.PCC is between service control layer and access/bearing bed, and at the certain QoS controlling mechanism of characteristic realization of mobile Access Network, the function that mainly provides has: control, control based on the charging of business data flow based on the customization information of user implementation strategy.
The functional frame composition of 3GPP PCC as shown in Figure 2.PCRF (Policy and Charging RuleFunction, strategy and charging rule functions) comprises the policy control decision-making and by the flow based charging controlled function.PCRF provides towards detection, gate, the QoS of the relevant business data flow of PCEF (Policy and Charging Enforcement Function, strategy and charge execution function) and has pressed the network control function of flow based charging (except the credit rating management).
PCEF comprises that business data flow detects, strategy is implemented and by the flow based charging function.This functional entity is positioned at gateway (GW).PCEF provides business data flow detection, user plane traffic to handle, trigger control plane session management, QoS enforcement, business datum flow measurement and mutual with charge system.SPR (Subscription Profile Repository, signatory inventory storehouse) storing user subscription data.OCS and OFCS are respectively Online Charging System and off-line accounting system, wherein in OCS, comprise the business data flow (Service Data Flow Based Credit Control) that the mobile network strengthens customized application logic business control point (CAMEL SCP) and controls based on credit.
There is very big-difference in " the resource and admission control " that the various criterion tissue proposes aspect framework, network range and the node type that relates to.Along with fixing fusion of moving, the inconsistency on framework and the interface is made by the NGN relevant device and network implementation will produce great influence.As shown in Figure 3, be RACF under the prior art and PCC, both can not collaborative work, promptly can not guarantee to move in heterogeneous network and the continuity and the service quality of business when switching.Along with the fusion of heterogeneous network, be badly in need of the resource hierarchy of control framework of a harmony, to satisfy user's business experience quality.
