Description
Technical field
The present invention relates to the communications field, particularly, relate to a kind of sending method, PD-FE, TRC-FE of QoS precedence information.
Background technology
At present, bearer network in the next generation network (Next Generation Network abbreviates NGN as) has adopted group technology, because service quality (the Quality ofService of group technology, abbreviate QoS as) defective, make QoS become one of major issue of NGN.Be directed to this, (the International Telecommunication Union of International Telecommunications Union, abbreviate ITU as) the QoS problem that resource accommodating control function (Resource and AdmissionControl Function abbreviates RACF as) solves the NGN bearer network proposed.
The major function of RACF is: based on the carrier policy rule, signatory QoS information of user and network internal available resources are carried out resource and admission control; RACF has shielded the difference of bearing bed to application layer, to bearing bed, makes bearing bed transmission entity can provide QoS to ensure under the guidance of RACF for the Media Stream of session the QoS best property of attribute mapping of application layer.
In the up-to-date RACF draft of ITU, the functional framework of RACF as shown in Figure 1.
In Fig. 1, policy deciding functional entity (Policy Decision Function Entity, abbreviate PD-FE as) be mainly used in and realize following function: based on medium streaming session information (from business control function body (Service Control Function, abbreviate SCF as) obtain by the Rs interface), user's transfer resource CAMEL-Subscription-Information is (from network attached controlled function entity (Network Attachment Control Function, abbreviate NACF as) obtain by the Ru interface) preliminary QoS resource decision made, then with transfer resource controlled function entity (Transport Resource Control Function Entity, abbreviate TRC-FE as) alternately to confirm whether to have enough QoS resources, make a final decision at last, and the policy execution functional entity (Policy Execute FunctionEntity abbreviates PE-FE as) that this decision-making is handed down to network terminal carried out.
TRC-FE is mainly used in and 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 is mainly used at PD-FE under guidance, carries out policy control (gate, bandwidth, traffic classification and mark, traffic shaping, two layers (being data link layer) and three layers of (being the IP layer) QoS mapping, collection and report resource use information etc.) in network terminal.
Transfer resource is carried out functional entity (Transport Resource Execute FunctionEntity, abbreviate TRE-FE as) be mainly used in the strategy execution of under the guidance of TRC-FE, carrying out the data link layer relevant with transmission technology, but concrete function and scope are not all clearly determined.
Home gateway strategy is carried out functional entity (CPN Gateway Policy ExecuteFunction Entity, abbreviate CGPE-FE as) be the policy enforcement function that resides on the home gateway, it is mainly used at user side carries out policy control to uplink traffic under PD-FE instructs.
At present, the fixed network operator's of communication network the digital home's business that provides is the integrated service that combines application, video, voice, data, and home gateway is a terminal equipment of supporting digital home business, as seen, the QoS control problem of home gateway is the key of development digital home of operator business.
In the concrete application scenarios that digital service is used, when the user initiates one when professional that QoS guarantees arranged, system at first can determine the QoS that this business is required by the negotiation of operation layer, service control layer is initiated resource request according to the QoS that consults to RACF then, QoS control strategy (particularly, generating the QoS control strategy by PD-FE) by RACF generation transport layer is handed down to transport layer policy execution entity (comprising the CGPE-FE on the home gateway) in order to carry out at last.CGPE-FE receives the strategy that RACF issues as the policy execution functional entity that resides on the home gateway, and according to this strategy the user service flow amount is carried out policy control.
With reference to figure 1, Fig. 2 shows RACF in the correlation technique and sends the flow process of QoS control strategy to home gateway, and this flow process comprises following processing procedure:
(201) SCF initiates resource request according to the QoS of operation layer negotiation to PD-FE, and this resource request is used to user's uplink service request resource, wherein carries user ID, professional required QoS information;
(202) PD-FE authorizes the resource request of validated user, and makes preliminary strategy and judge, obtains this user's who prestores CAMEL-Subscription-Information, perhaps obtains this user's CAMEL-Subscription-Information alternately with NACF;
(203) PD-FE sends resource request to TRC-FE, carry Media Stream five-tuple (source end/destination address, source end/destination port numbers, protocol type), bandwidth information, IP layer QoS precedence information in this resource request, TRC-FE makes judgement according to current resource situation to request, when having available resources, return response to PD-FE;
(204) PD-FE makes final admittance strategy judgement according to Resource Availability, generate the QoS control strategy, carry the Media Stream descriptor in this QoS control strategy, comprising: Media Stream five-tuple (that is, source end/destination address, protocol type, source end/destination port numbers), bandwidth, network layer QoS information (being IP layer QoS precedence information) etc.;
(205a, b) PD-FE issues to CGPE-FE and PE-FE respectively and carries IP layer QoS precedence information QoS control strategy;
(206a, b) CGPE-FE and PE-FE reply to PD-FE respectively after receiving the QoS control strategy and reply;
(207) PD-FE replys to SCF answer resource request.
Present home gateway has two types: route type and bridge type.For route type home gateway, it is handled at the IP layer forwarding of data, can transmit message according to IP layer QoS priority.For the bridge type home gateway, owing to only carry out data forwarding in data link layer (data link layer), and function is simple, usually do not support the processing of IP layer QoS precedence information yet, therefore, if PD-FE only carries IP layer QoS priority in the QoS control strategy that CGPE-FE issues, this precedence information can not be handled and use to this home gateway, so just can't guarantee the QoS of uplink traffic.
