Description
Technical field
The present invention relates to the communications field, relate more specifically to a kind of method for controlling quality of service of Internet service.
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.
TISPAN (Telecommunication and Internet converged Services and Protocolsfor Advanced Networking, telecommunications and the Internet converged services and high-level network protocol) be ETSI subordinate's a normal structure, it has set up the particular study group, be devoted to the formulation work of NGN technical standard, TISPAN is divided into operation layer and transport layer with the NGN framework, introduced NASS (Network Attachment SubSystem at transmission control layer, Network Attachment Subsystem) with RACS (Resource andAdmission Control Subsystem, Resource and Admission Control Sub-system), NASS is responsible for the upper-layer service layer independent user access-in management is provided, and RACS then solves the QoS problem of NGN bearer network.
RACS is responsible for the resource requirement of operation layer is associated with the resource allocation of transport layer, mainly finishes functions such as policy control, resource reservation, admittance control, NAT (Network Address Translation, network address translation) pass through.RACS for operation layer provides the control service of transport layer, makes that (User Equipment UE) can obtain the required service quality assurance to user terminal by a series of qos policys.
In the up-to-date draft of RACS, the functional framework of RACS is provided, as shown in Figure 1, among the figure:
SPDF (Service-based Policy Decision Function, strategy decisive function based on business) according to AF (Application Function, application function) resource request is selected local policy, and request is mapped to the IP qos parameter, send to x-RACF and BGF (Border GatewayFunction, Border Gateway Function), to ask corresponding resource.
X-RACF (generic Resource and Admission Control Function, accommodating access resource controlled 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.X-RACF can be by the e4 reference point from Network Attachment Subsystem (Network Attachment Sub-System, NASS) obtain network attachment information and user QoS CAMEL-Subscription-Information, 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's QoS CAMEL-Subscription-Information.
BGF (Border Gateway Function, Border Gateway Function) (realization Core Border Gateway Function) between Access Network and core net also can be at the gateway between two core net.BGF finishes NAT, gate, QoS mark, bandwidth constraints, use measurement and source synchronous function under the control of SPDF.
RCEF (Resource Control Enforcement Function, Resource Control Enforcement Function) is arranged in the strategy execution body of transport layer functionality entity, it can reside in any network segment (access, core) of bearing bed or the boundary point of the network segment, implement x-RACF by the strategy that the Re reference point sends, finish functions such as gate, QoS mark, bandwidth constraints.How RACS controls as yet not standardization to the RCEF that is in the core net at present.
BTF (Basic Transmission Function, basic transmission function) is the logic entity that is arranged in the basic controlled function of the support of transmission equipment and basic forwarding capability etc.
Control bearer network (no metropolitan area network for RACS in the current standard, operation commercial city, most of Europe is such network) configuration diagram as shown in Figure 2, RACS reaches Business Stream is carried out policy control by control Access Network IP boundary point, core net boundary point.
At first UE and AF carry out the signaling negotiation of operation layer, AF initiates resource request according to the QoS that consults to RACS, RACS receives request, make the admittance decision-making according to user signing contract information, transfer resource situation and carrier policy, if admit, then generate control strategy, the content of strategy comprises (Business Stream descriptor, upstream and downstream bandwidth, QoS rank etc.), RACS gives corresponding network segment boundary Control point with policy distribution, according to strategy corresponding business stream is implemented qos policy by control point equipment.
Existing standard lacks the policy control to core net, only control Access Network IP boundary point and core net boundary node, for VOIP class business, because Business Stream is all from terminal-to-terminal service, therefore respectively the access point of calling and called terminal is carried out the QoS that policy control can effectively guarantee two-way services stream.
For the internet-class business, its service server all is in the core net usually, the two ends of its Business Stream are user terminal and service server, if only control core net edge device (referring to top said core net boundary point), the QoS from service server to the downlink traffic the core net edge device can't guarantee so.
Though some operators can dispose independently core net for the high business of some qos requirements (as IPTV etc.), mode by underloading guarantees the QoS of these business in core net, but this is that the mode cost of a core net of every class service construction is very high, is not a universal scheme.
