Description
Technical field
The present invention relates to the next generation network communication field, relate more specifically to realize in the next generation network method and the device of multi-granularity resource control.
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 Bearer Network, converged fixed communication and mobile communication.NGN can provide abundanter multimedia service.
ITU-T (International Telecommunication Union TelecommunicationStandardization Sector, ITU Telecommunication Standardization Sector) and TISPAN (Telecommunication and Internet converged Services and Protocols forAdvanced Networking, the standardization body in Europe) all set up the particular study group separately, be devoted to the formulation work of NGN technical standard, they have proposed RACF (Resource andAdmission Control Function respectively, resource accommodating control function) and RACS (Resource andAdmission Control Subsystem, Resource and Admission Control Sub-system) solves QoS (Quality ofService, the service quality) problem of NGN bearer network.
TISPAN is divided into operation layer and transport layer with the NGN framework, introduced NASS (Network Attachment SubSystem at transport layer, Network Attachment Subsystem) and RACS, be responsible for the upper-layer service layer independent user access-in management and resource control assurance function are provided.
The function structure of TISPAN RACS as shown in Figure 1.RACS is associated the resource requirement of operation layer with the resource allocation of network carrying layer, mainly finish functions such as policy control, resource reservation, admittance control, NAT (Network Address Translation, network address translation) pass through.RACS for application provides the control service of transport layer, makes user terminal can obtain required service by a series of qos policys.
RACS is made up of two entities: SPDF (Service-based Policy Decision Function, strategy decisive function based on business) and Access-Resource and Admission Control Function (Access-Resource and AdmissionControl Function, accommodating access resource controlled function).
Wherein, SPDF provides unified interface to application layer, and the concrete access style of shielding bottom-layer network topological sum provides the policy control based on business.SPDF is according to application function (ApplicationFunction, AF) local policy is selected in request, and request is mapped to the IP qos parameter, sends to Access-Resource and Admission Control Function and BGF (Border Gateway Function, Border Gateway Function), to ask corresponding resource.
Access-Resource and Admission Control Function control Access Network has the function that control of admitting and network strategy converge.Access-Resource and Admission Control Function receives from SPDF and asks, and realizes admitting control based on the strategy of being preserved then, accepts or refuses transmitting the request of resource.Access-Resource and Admission Control Function obtains network attachment information and user QoS inventory information by the e4 reference point from NASS, thereby can determine available network resources according to network location information (for example inserting the address of user's physical node), simultaneously when the processing resource allocation request with reference to user QoS inventory information.
Comprise two kinds of functional entity: BGF and RCEF (Resource ControlEnforcement Function, Resource Control Enforcement Function) in the transport layer.Wherein, BGF is a bag (Packet-to-Packet) gateway, can realize Core Border Gateway Function between Access Network and core net; Also can between two core net, realize interconnected Border Gateway Function.BGF finishes under the control of SPDF that NAT passes through, gate, QoS mark, bandwidth constraints, use measurement and source synchronous function.RCEF implements Access-Resource and Admission Control Function by two layers/three layers (L2/L3) Media Stream strategy that the Re reference point sends, and finishes functions such as gate, QoS mark, bandwidth constraints.
In the up-to-date draft of the RACF that ITU-T announced in April, 2007, provide the functional framework of RACF, as shown in Figure 2.The same with the function structure of the TISPAN RACS that shows of Fig. 1, RACF also is made up of two parts: policy deciding functional entity (Policy Decision Functional Entity, PD-FE) and transmit the resource control function entity (Transport Resource Control FunctionalEntiy, TRC-FE).
PD-FE and tranmission techniques are irrelevant, and service control function (Service Control Functions, SCF) also irrelevant.The business information that PD-FE policing rule Network Based, SCF provide, the network attachment function of dominant (Network Attachment Control Functions, 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 then.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 tranmission techniques.TRC-FE is responsible for collecting and safeguarding the topological sum resource state information that transmits net, availability based on topology, connectivity, network and node resource, and, carry out and admit control transmitting network 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 reference point request TRC-FE detects or decision is asked.
(Policy Enforcement Functional Entity, PE-FE) (Transport Resource Enforcement FunctionalEntity TRE-FE) forms transport layer with transmitting resource execution functional entity 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, be the key node of supporting that dynamic QoS control, port address conversion and control and NAT pass through.
PD-FE is a policy deciding functional entity, it can make preliminary QoS resource decision based on medium streaming session information (obtaining from SCF 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 should make a strategic decision and be handed down to PE-FE by the Rw interface and carry out.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 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.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.
RACS or RACF are the important component parts of next generation network.RACS or RACF, are associated the resource requirement of operation layer for application provides control service based on transmission by a series of strategies with the resource allocation of network carrying layer, mainly finish functions such as policy control, resource reservation, admittance are controlled, NAT passes through.
Because in the practical application, there is multiple granularity in resource control, for example Media Stream level, application layer, session level, convergence layer etc., under present technical conditions, application layer requires the resource control of many granularities, but, cause transport layer equipment not discern and maybe can not support the resource control granularity that Access-Resource and Admission Control Function or PD-FE require because Access-Resource and Admission Control Function and PD-FE do not possess the resource control function of many granularities.Like this, the policy installation order that Access-Resource and Admission Control Function or PD-FE issue or other order, transport layer equipment can not correct execution, makes network traffics increase, and has wasted Internet resources.
Summary of the invention
