Abstract

A sending method for Quality of Service (QoS) priority information and a Policy Decision Functional Entity (PD-FE) and a Transport Resource Control Functional Entity (TRC-FE) are provided. The method includes the following steps. The PD-FE receives a resource request from a Service Control Functions (SCF) entity. The PD-FE generates the second layer QoS priority information according to user’s subscription information and the network layer QoS information. The PD-FE sends the second layer QoS priority information to the Customer Premises Network (CPN) Gateway Policy Enforcement Functional Entity (CGPE-FE). The method, the PD-FE and the TRC-FE enable the bridged home gateway to use the second layer QoS priority information efficiently, and ensure the QoS of the uplink flow.

Description

QoS优先级信息的发送方法、 PD-FE、 TRC-FE 技术领域本发明涉及通信领域，具体地，涉及一种 QoS优先级信息的发送方法、 PD-FE ( Policy Decision Function Entity , 策略决策功能实体）、 TRC-FE ( Transport Resource Control Function Entity, 传输资源控制功能实体）。背景技术目前，下一代网络（ Next Generation Network , 筒称为 NGN ) 中的载网采用了分组技术，由于分组技术服务质量（Quality of Service, 筒称为 QoS ) 的缺陷，使得 QoS 成为 NGN 的重要问题之一。针对于此，国际电信联盟 ( International Telecommunication Union, 筒称为 ITU )提出了资源接纳控制功能（ Resource and Admission Control Function, 筒称为 RACF ),以解决 NGN 载网的 QoS问题。 The present invention relates to the field of communications, and in particular to a method for transmitting QoS priority information, and a PD-FE (Policy Decision Function Entity) ), TRC-FE (Transport Resource Control Function Entity). BACKGROUND At present, a carrier network in a Next Generation Network (NGN) adopts a packet technology, and QoS becomes an important part of NGN due to a defect of a packet quality service quality (QoS). One of the problems. In response to this, the International Telecommunication Union (ITU) calls the Resource and Admission Control Function (RACF) to solve the QoS problem of the NGN carrier network.

RACF 的主要功能在于：基于运营商策略规则，对用户签约 QoS信息和网络内部可用资源进行资源接纳控制； RACF对应用层屏蔽了载层的差异，将应用层的 QoS属性映射到承载层，使得承载层传输实体在 RACF的指导下能够为会话的媒体流提供 QoS保障。在 ITU最新的 RACF草案中， RACF的功能才11架如图 1所示。在图 1 中，策略决策功能实体 PD-FE主要用于实现以下功能：基于媒体流会话信息（通过 Rs接口从业务控制功能实体 ( Service Control Function, 筒称为 SCF )获取）、用户的传输资源签约信息（通过 Ru接口从网络附属控制功能实体（ Network Attachment Control Function, 筒称为 NACF )获取 ) k. 出初步的 QoS资源决策，然后与传输资源控制功能实体 TRC-FE交互，以确认是否有足够的 QoS资源，最后丈出一个最终决策，并将该决策下发给网络端的策略执行功能实体 ( Policy Execute Function Entity, 筒称为 PE-FE )执行。 The main functions of the RACF are: based on the operator policy rules, the user subscribes to the QoS information and the resources available in the network for resource admission control; the RACF shields the application layer from the difference of the carrier layer, and maps the QoS attributes of the application layer to the bearer layer. The bearer layer transport entity can provide QoS guarantee for the media stream of the session under the guidance of the RACF. In the latest ITU draft of the RACF, the functions of the RACF are shown in Figure 1. In Figure 1, the policy decision function entity PD-FE is mainly used to implement the following functions: based on the media stream session information (obtained from the service control function entity (SCF) through the Rs interface), the user's transmission resource Signing information (obtained from the Network Attachment Control Function (NACF) through the Ru interface) k. Preliminary QoS resource decision, and then interact with the transmission resource control function entity TRC-FE to confirm whether there is Sufficient QoS resources, and finally a final decision is made, and the decision is sent to the network's Policy Execute Function Entity (PE-FE).

TRC-FE主要用于负责资源控制 ,它监控网络中的资源并收集相关信息 , 在 PD-FE请求资源时，才艮据具体的资源状况给予应答。 PE-FE主要用于在 PD-FE的指导下，在网络端进行策略控制（门控、带宽、流量分类和标记、流量整形、二层（即数据链路层）和三层（即 IP 层） QoS映射、收集和报告资源使用信息等）。传输资源执行功能实体 ( Transport Resource Execute Function Entity, 筒称为 TRE-FE ) 主要用于在 TRC-FE的指导下，进行与传输技术相关的数据链路层的策略执行，但是具体的功能和范围都没有明确规定。家庭网关策略执行功能实体 ( CPN Gateway Policy Execute Function Entity , 筒称为 CGPE-FE ) 是驻留在家庭网关上的策略执行功能，它主要用于用户端，在 PD-FE指导下对上行流量进行策略控制。目前，通信网的固网运营商提供的数字家庭业务是结合了应用、视频、语音、数据的综合业务，而家庭网关是支持数字家庭业务的终端设备，可见，家庭网关的 QoS控制问题是运营商发展数字家庭业务的关键。在数字业务应用的具体的应用场景中，当用户发起一个有 QoS保证的业务时， ***首先会通过业务层的协商确定该业务所需的 QoS, 然后业务控制层才艮据协商的 QoS向 RACF发起资源请求，最后由 RACF生成传输层的 QoS控制策略（具体地，由 PD-FE生成 QoS控制策略）下发给传输层策略执行实体（包括家庭网关上的 CGPE-FE ) 用以执行。 CGPE-FE作为驻留在家庭网关上的策略执行功能实体，接收 RACF下发的策略，并根据该策略对用户的业务流量进行策略控制。参考图 1 , 图 2示出了相关技术中 RACF向家庭网关发送 QoS控制策略的流程，该流程包括如下处理过程（ 201至 207 ): The TRC-FE is mainly used for resource control. It monitors resources in the network and collects related information. When the PD-FE requests resources, it responds according to the specific resource status. PE-FE is mainly used for policy control on the network side under the guidance of PD-FE (gating, bandwidth, traffic classification and labeling, traffic shaping, Layer 2 (data link layer) and Layer 3 (ie IP layer). ) QoS mapping, collection and reporting of resource usage information, etc.). The Transport Resource Execute Function Entity (TRE-FE) is mainly used to perform the policy implementation of the data link layer related to the transmission technology under the guidance of the TRC-FE, but the specific functions and scopes. There is no clear regulation. The CPN Gateway Policy Execute Function Entity (CPE Gateway Policy Entity) is a policy enforcement function that resides on the home gateway. It is mainly used by the UE to perform upstream traffic under the guidance of the PD-FE. Policy control. At present, the digital home service provided by the fixed network operator of the communication network is an integrated service combining application, video, voice and data, and the home gateway is a terminal device supporting the digital home service. It can be seen that the QoS control problem of the home gateway is operation. The key to developing digital home business. In a specific application scenario of the digital service application, when the user initiates a QoS-guaranteed service, the system first determines the QoS required for the service through negotiation of the service layer, and then the service control layer forwards the RASF according to the negotiated QoS. The resource request is initiated, and finally the QoS control policy of the transport layer generated by the RACF (specifically, the QoS control policy generated by the PD-FE) is sent to the transport layer policy enforcement entity (including the CGPE-FE on the home gateway) for execution. The CGPE-FE acts as a policy enforcement function entity that resides on the home gateway, receives the policy delivered by the RACF, and performs policy control on the user's service traffic according to the policy. Referring to FIG. 1, FIG. 2 shows a flow of a RAC control policy sent by a RACF to a home gateway in the related art, where the process includes the following processing procedures (201 to 207):

( 201 ) SCF根据业务层协商的 QoS向 PD-FE发起资源请求，该资源请求用于为用户的上行业务请求资源，其中携带有用户标识、业务所需的 QoS 信息； ( 202 ) PD-FE对合法用户的资源请求进行授权 , 并做出初步的策略判断，获取预存的该用户的签约信息 , 或者与 NACF交互获取该用户的签约信息； (201) The SCF initiates a resource request to the PD-FE according to the QoS negotiated by the service layer, where the resource request is used to request a resource for the uplink service of the user, where the user identifier and the QoS information required by the service are carried; (202) PD-FE Authorizing the resource request of the legitimate user, and making a preliminary policy judgment, obtaining the pre-stored subscription information of the user, or interacting with the NACF to obtain the subscription information of the user;

( 203 ) PD-FE向 TRC-FE发送资源请求，该资源请求中携带有媒体流五元组（即，源端 /目的端地址、源端 /目的端端口号、 †办议类型）、带宽信息、 IP层 QoS优先级信息， TRC-FE根据当前资源状况对请求做出判断，当存在可用资源时，向 PD-FE返回回应； ( 203 ) The PD-FE sends a resource request to the TRC-FE, where the resource request carries a media stream quintuple (ie, source/destination address, source/destination port number, † negotiation type), and bandwidth. information, IP layer QoS priority information, the TRC-FE determines the request according to the current resource status, and returns a response to the PD-FE when there is available resources;

( 204 ) PD-FE根据资源可用性做出最终的接纳策略判断，生成 QoS控制策略，该 QoS控制策略中携带有媒体流描述信息，其中包括：媒体流五元组（即，源端 /目的端地址、 †办议类型、源端 /目的端端口号）、带宽、网络层 QoS信息（即， IP层 QoS优先级信息 ) 等； (204) The PD-FE performs a final admission policy judgment according to the resource availability, and generates a QoS control policy, where the QoS control policy carries the media stream description information, where: the media stream quintuple (ie, the source/destination end) Address, † negotiation type, source/destination port number), bandwidth, network layer QoS information (ie, IP layer QoS priority information), etc.;

( 205a, b ) PD-FE分别向 CGPE-FE和 PE-FE下发携带有 IP层 QoS优先级信息的 QoS控制策略； ( 205a, b ) The PD-FE sends a QoS control policy carrying the QoS priority information of the IP layer to the CGPE-FE and the PE-FE, respectively;

( 206a, b ) CGPE-FE和 PE-FE在接收到 QoS控制策略后分别向 PD-FE 回复应答； (206a, b) The CGPE-FE and the PE-FE respectively reply to the PD-FE after receiving the QoS control policy;

( 207 ) PD-FE向 SCF回复资源请求应答。目前的家庭网关具有两种类型：路由型和桥接型。对于路由型家庭网关，其对数据的转发处理在 IP层，可以根据 IP层 QoS优先级对报文进行转发。而对于桥接型家庭网关，由于其只在数据链路层进行数据转发，并且功能筒单，通常不支持 IP层 QoS优先级信息的处理。因此，如果 PD-FE向 CGPE-FE 下发的 QoS控制策略中只携带有 IP层 QoS优先级，桥接型家庭网关将不能处理并使用该优先级信息，这样就无法保证上行流量的 QoS。综上所述，针对目前相关技术中存在的桥接型家庭网关无法处理接收到的 QoS控制策略中的 IP层 QoS优先级信息的问题，尚未提出有效的解决方案。发明内容考虑到相关技术中存在的桥接型家庭网关无法处理接收到的 QoS控制策略中的 IP层 QoS优先级信息的问题而做出本发明，为此，本发明的主要目的在于提供一种改进的 QoS 优先级信息的发送方法、 PD-FE、 TRC-FE, 以解决相关技术中的上述问题。为达到上述目的，根据本发明的一个方面，提供了一种服务质量 QoS 优先级信息的发送方法。才艮据本发明的 QoS优先级信息的发送方法包括： PD-FE接收来自 SCF 的资源请求； PD-FE根据用户的签约信息和网络层 QoS信息 , 生成二层 QoS 优先级信息； PD-FE将二层 QoS优先级信息发送给 CGPE-FE。优选地， PD-FE根据用户的签约信息和网络层 QoS信息，生成二层 QoS 优先级信息，具体包括： PD-FE根据签约信息中的接入网络类型，以及预定义的网络层 QoS信息与二层 QoS优先级信息的对应关系确定该二层 QoS优先级信息。优选地，在 PD-FE将二层 QoS优先级信息发送给 CGPE-FE之前，该方法还包括：通过在 PD-FE与 CGPE-FE之间的 Rh接口中增加二层 QoS优先级字段来扩展 Rh接口，其中，增加的二层 QoS优先级字段用于携带二层 QoS优先级信息。优选地， PD-FE将二层 QoS优先级信息发送给 CGPE-FE的操作包括： PD-FE生成 QoS控制策略，并将二层 QoS优先级信息携带在 QoS控制策略中； PD-FE将携带有二层 QoS优先级信息的 QoS控制策略发送给 CGPE-FE。优选地，资源请求为资源初始化请求或资源^ ^丈请求。优选地，该方法还包括： CGPE-FE根据接收到的二层 QoS优先级信息，进行上行业务。才艮据本发明的另一个方面，提供了一种服务质量 QoS优先级信息的发送方法。才艮据本发明的 QoS 优先级信息的发送方法包括： TRC-FE 接收来自(207) The PD-FE replies to the SCF with a resource request response. There are two types of current home gateways: routed and bridged. For the routing type home gateway, the data forwarding processing is performed at the IP layer, and the packet can be forwarded according to the IP layer QoS priority. For the bridge type home gateway, since it only performs data forwarding at the data link layer, and the function is single, the processing of the IP layer QoS priority information is usually not supported. Therefore, if the QoS control policy delivered by the PD-FE to the CGPE-FE carries only the IP layer QoS priority, the bridged home gateway will not be able to process and use the priority information, thus the QoS of the upstream traffic cannot be guaranteed. In summary, the problem that the bridging type home gateway existing in the related art cannot process the IP layer QoS priority information in the received QoS control policy has not yet proposed an effective solution.

As shown in FIG. 3, the method for transmitting QoS priority information according to the method embodiment of the present invention includes steps S302 to S S306. The specific processing shown in Figure 3 is as follows: (1) Step S302

The Layer 2 QoS priority information ensures the QoS of its upstream traffic. Based on the above description, an example of a specific application method of the QoS priority information transmission method in the first embodiment of the method of the present invention will be described below. In the first and second embodiments to be described below, the Rh interface is first extended by adding a Layer 2 QoS priority information field, and then the PD-FE is based on the access network type and network layer QoS of the home gateway in the user subscription information. The information determines the corresponding Layer 2 QoS priority information, and the Layer 2 QoS priority information is carried in the QoS control policy, and the QoS control policy is sent to the CGPE-FE through the extended Rh interface.
