Description

移动通信系统及使用拜访网络应用功能业务的方法 The mobile communication system and method of use of the visited service network application function

技术领域 FIELD

本发明涉及移动通信技术,特别涉及用户设备在拜访网络中使用拜访网络应用功能业务的相关系统和方法。 The present invention relates to mobile communication technologies, and particularly relates to systems and methods related to a user equipment in the visited network application function in the visited network services.

背景技术 Background technique

通用分组无线业务(General Packet Radio Service,简称"GPRS")网络是一种基于全球移动系统(Global System of Mobility,简称"GSM")网络的新一代蜂窝移动通信网络。 General packet radio service (General Packet Radio Service, abbreviated "GPRS") network is a Global System for Mobile-based (Global System of Mobility, referred to as "GSM") cellular mobile communication network, a new generation network. 为了支持GPRS功能,在现有GSM网络中需要增加一些节点,如网关GPRS支持节点(Gateway GPRS Support Node, 筒称"GGSN")、服务GPRS支持节点(Serving GPRS Support Node,筒称"SGSN"),它们都属于GPRS支持节点(GPRS Support Node,简称"GSN,,)。 In order to support GPRS function, the existing GSM networks need to increase the number of nodes, such as a gateway GPRS support node (Gateway GPRS Support Node, tube called "GGSN"), serving GPRS support node (Serving GPRS Support Node, tube called "SGSN") they all belong to the GPRS support node (GPRS support node, referred to as "GSN ,,).

另外,在第三代移动通信(The Third Generation,简称"3G,,)中,例如宽带码分多址(Wideband Code Division Multiple Access,简称"WCDMA") 的核心网(Core Net,简称"CN")中,也支持GPRS功能,同样有GGSN 和SGSN等GSN节点。 In addition, third generation mobile communication (The Third Generation, abbreviated "3G ,,), such as wideband CDMA (Wideband Code Division Multiple Access, referred to as" WCDMA ") core network (Core Net, referred to as" CN " ), but also support GPRS function, the same GGSN and SGSN nodes and other GSN.

其中,GGSN作为GPRS的核心网络设备之一,主要功能是网络接入控制、计费信息收集、路由选择和转发、移动性管理、边界网关(Border Gateway, 简称"BG")等。 Wherein one of a GPRS GGSN as core network device, the main function is network access control, billing information is collected, routing and forwarding, mobility management, border gateway (Border Gateway, referred to as "BG") and the like.

目前业界在GPRS网络上实现智能业务的一种主要方式是GGSN/业务交换功能(GGSN/Service Switch Function,简称"GGSN/SSF")方式,这种GGSN/SSF方式是在GGSN上实现智能业务的交换功能。 Currently one of the main ways the industry to achieve intelligent service on the GPRS network is GGSN / Service Switching Function (GGSN / Service Switch Function, referred to as "GGSN / SSF") mode, the GGSN / SSF approach is intelligent business in the GGSN switching function. 这种方式在业务交换点(Service Switch Point,筒称"SSP")和业务控制点(Service Control Point,简称"SCP,,)之间的接口都采用了第三代合作伙伴项目(3rd Generation Partnership Project,简称"3GPP" ) TS 23.078标准制定的移动网络增强逻辑的客户化应用(Customized Applications for Mobile network Enhanced Logic, 简称"CAMEL")接口。 In this way a service switching point (Service Switch Point, tube called "SSP") and a service control point (Service Control Point, referred to as the "SCP ,,) have adopted the interface between the Third Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") TS 23.078 standards of customer mobile network enhanced logic applications (customized applications for mobile network enhanced logic, referred to as "CAMEL") interface.

GPRS网络中计费信息由SGSN和GGSN收集并发送给计费网关功能(Charging Gateway Functionality,筒称"CGF" ) 。 GPRS network billing information is collected and sent by the SGSN and GGSN to the Charging Gateway Function (Charging Gateway Functionality, tube called "CGF"). CGF从SGSN中收集的呼叫详细记录(Call Detail Record,简称"CDR")称为SGSN呼叫详细记录(SGSN誦Call Detail Record,简称"S-CDR"),从GGSN收集的CDR 称为GGSN呼叫详细记录(GGSN - Call Detail Record, "G-CDR")。 CGF collected call detail records from the SGSN (Call Detail Record, referred to as "CDR") called Call Detail Record SGSN (SGSN recite Call Detail Record, referred to as "S-CDR"), collected from the GGSN GGSN called CDR Call Detail record (GGSN - Call Detail record, "G-CDR").

在3GPP R5 (版本5)中,采用基于流的计费(Flow Based Charging, 筒称"FBC")方式,具体地在3GPPTS 23.125标准中有FBC的系统结构、 功能要求以及消息流程等方面的描述。 In 3GPP R5 (version 5), using stream-based charging (Flow Based Charging, said cartridge "FBC") mode, there are specifically described aspects of FBC system architecture, functional requirements, and the like in the message flow 3GPPTS 23.125 standard .

在3GPP R6(版本6)中提供了基于业务的本地策略(Service Based Local Policy,简称"SBLP")控制方案和基于业务数据流(Service Data Flow,简称"SDF")的FBC计费控制方案。 Provides local policy (Service Based Local Policy, referred to as "SBLP") FBC-based control scheme and charging control program service data flow (Service Data Flow, referred to as "SDF") based services in 3GPP R6 (version 6).

.为了提高系统的效率,简化操作,降低时延,需要考虑将策略控制和计费控制进行融合,融合后的机制即为3GPPR7的策略与计费控制(Policyand Charging Control,简称"PCC"),如图1所示。 In order to improve the efficiency of the system, streamline operations, reduce latency, you need to consider the policy control and charging control fusion, fusion is the mechanism after 3GPPR7 policy and charging control (Policyand Charging Control, referred to as "PCC"), As shown in Figure 1. 这种合并有利于更好地在GGSN以及其它接入网的网关(Gateway,简称"GW")中提供优化的实时交互操作体系。 This consolidation is conducive to better provide real-time interaction optimization of operating system and other gateways in the GGSN (Gateway, referred to as "GW") of the access network.

与FBC —样,在PCC中操作的基本对象也是SDF。 And FBC - like, basic operation of the object in the PCC is SDF. 类似地,在FBC中使用计费规则(charging rule),而在PCC中所有的操作都通过PCC规则(rule),来表达并传送到网络中的执行功能实体之中。 Similarly, using the charging rules (charging rule) in FBC, and all operations are, expressed and transferred into the network entity to perform the functions PCC rules (rule) in the PCC. 签约信息、新的绑定机制以及PCC规则的结合,使得PCC可以适用更一般的应用环境,例如, 有应用功能(Application Function,简称"AF")或无AF、 GPRS承载或非GPRS承载等等,还为更多新应用的实施提供了一个更为通用化的操作平台。 Binding subscription information, the new PCC rules and the binding mechanism, so that the PCC may be applicable to more general application environments, for example, there is an application function (Application Function, referred to as "AF") with or without the AF, GPRS bearer or bearers like GPRS , also provides a more universal operating platform for the implementation of more new applications.

这种PCC机制中基于SDF的计费规则功能(Charging Rules Function, 简称"CRF")称为策略与计费规则功能(Policy and Charging Rules Function, 简称"PCRF"),既包含了SBLP中策略决策功能(Policy Decision Function, 简称"PDF"),又包含了FBC中CRF的功能,并向GW提供服务质量(Quality of Service,筒称"QoS")授权信息以及计费规则,如图2所示。 This PCC mechanism of SDF-based charging rules function (Charging Rules Function, referred to as "CRF") called Policy and Charging Rules Function (Policy and Charging Rules Function, referred to as "PCRF"), both included in the policy decision SBLP function (Policy Decision function, referred to as "PDF"), but also contains the FBC function in CRF, GW and provide quality of service (quality of service, said barrel "QoS") authorization information and accounting rules, shown in Figure 2 .

其中,签约规格库(Subscription Profile Repository,简称"SPR")实体包含了和用户签约相关的信息,这些信息对于PCRF进行基于签约的策略控制以及承载级的计费控制都是十分有用的。 Among them, contract specifications library (Subscription Profile Repository, referred to as "SPR") entity contains the relevant information and user subscription, the subscription-based information for PCRF policy control and charging control bearer level are very useful.

类似地,如图1所示的GW实体包含了SBLP的策略执行点(Policy Enforcement Point,简称"PEP")和FBC的流量平面功能(Traffic Plane Function,简称"TPF"),并提供用户面流量的处理和QoS处理,还提供基于SDF的匹配和统计功能。 Similarly, GW entity shown in Figure 1 contains the policy enforcement point SBLP (Policy Enforcement Point, referred to as "PEP") and FBC traffic plane function (Traffic Plane Function, referred to as "TPF"), and provides user plane traffic processing and QoS processing, based on SDF also provides matching and statistical functions.

另外,在线计费系统(Online Charging System,简称"OCS")由SCP 和信用控制功能(Credit Control Function,筒称"CCF")两个功能实体组成,其中CCF对在线计费时的用户信用进行管理。 In addition, the online charging system (Online Charging System, referred to as the "OCS") by the SCP and credit control functions (Credit Control Function, drum called "CCF") two functional entities, which CCF users were online charging credit when management. 当用户使用业务时,CCF 都对该用户的信用进行鉴权,并向TPF下发用户可以使用的信用。 When a user using the service, CCF will authenticate the user's credit, and issued a credit user can use the TPF.

对应于GPRS网络,AF为分组数据网(Packet Data Network,简称"PDN") 中的一个业务网关,或是业务服务器。 Corresponds to GPRS network, the AF is a packet data network (Packet Data Network, referred to as "PDN") a service gateway or a service server. 而TPF为GGSN, CRF则为新增的逻辑实体。 The TPF was the new logical entities GGSN, CRF. 其中,TPF的功能是计费规则执行点,CRF是计费规则的控制点。 Wherein, TPF performs the charging rule function point, CRF is the control point of charging rules.

拜访公共陆地移动通信网(Visited PLMN,筒称"VPLMN"),也即UE在漫游网络中所接入的拜访网络(VisitedNetwork)的PCRF和策略与计费执行功能(Policy and Charging Enforcement Function,简称"PCEF")逻辑结构如图3所示,其中,拜访网络中的PCRF称为V-PCRF、 PCEF称为V-PCEF、 GW称为V-GW,类似地在归属网络(HomeNetwork)中的PCRF Visited Public Land Mobile Network (Visited PLMN, said cartridge "VPLMN"), in the roaming network visited network accessed (VisitedNetwork) and the PCRF policy and charging enforcement function (Policy and Charging Enforcement Function i.e. UE, Acronym "PCEF") the logical structure shown in Figure 3, wherein the PCRF in the visited network is called V-PCRF, PCEF called V-PCEF, GW called V-GW, similarly PCRF in the home network (Homenetwork) of

9称为H-PCRF、 PCEF称为H-PCEF、 GW称为H-GW。 9 is called H-PCRF, PCEF called H-PCEF, GW called H-GW.

具体地说,V-PCRF可能支持的功能有:包括策略控制决策和FBC控制功能,根据业务流检测选通(gating) 、 QoS和FBC控制、向PCEF提供网络控制,根据运营商需求在接受归属网络业务信息前申请安全过程,在存储归属网络提供的信息之前可能检测其是否同本地运营商定义的策略规则一致,并可能会根据检测不一致的结果拒绝归属网络的请求。 Specifically, V-PCRF may support functions: FBC comprises policy control decision and control functions, according to the traffic flow detection gate (gating), QoS and FBC control to the PCEF provides network control, according to the operator needs to accept ownership business information network security before the application process, it is possible to detect whether the same policy rule definitions are consistent with local operators before the information is stored in the home network provides, and may reject the request based on the home network inconsistent test results.

现有技术的另一种网络构架是AF在拜访网络,或者在第三方网络中, 且第三方网络和V-PCRF有直接的连接。 Another prior art network architecture is the AF visited network, or third party network, and third-party network, and V-PCRF has a direct connection. 在这种情况下,策略控制完全由拜访网络执行,拜访网络和归属网络之间没有直接的信令交互。 In this case, policy control is implemented entirely by the visited network, there is no direct interaction between the signaling visited and home networks. V-PCRF提供策略规则的方式必须在和归属网络的漫游协议中预置。 V-PCRF provides policy rules must be preset in the way of the home network and a roaming agreement. 如要依赖漫游协议来进行拜访网络的策略控制,则需要对现有的漫游协议进行修改,且修改的内容是有待下一步研究(For Further Study,'简称"FFS")的,还需要研究如何处理拜访网络中的计费、归属网络的AF是否参与业务提供等问题。 To rely on roaming agreements to the visited network policy control, you need to modify the existing roaming agreements, and modify the content is to be further research (For Further Study, 'referred to as "FFS"), but also need to study how handling billing visited network, the home network whether the AF and other service providers involved in the issue.

在实际应用中,上述方案存在以下问题:UE在漫游网络中所接入的业务计费不准确。 In practical applications, the presence of the above-described embodiment the following problems: UE in the access network in a roaming service charging inaccurate.

造成这种情况的主要原因在于,由于目前对于在H-PCRF和V-PCRF之间所传送的信息内容、方式和策略都没有定义,所以对UE在漫游网络中所接入的业务计费的策略和计费规则不灵活,导致计费不准确。 Main reason for this is that, due to the current informational content between the H-PCRF and V-PCRF transmitted, and the way the policy is not defined, so the UE in the access network in a roaming service charging policy and charging rules are not flexible, resulting in inaccurate billing.

发明内容 SUMMARY

UE请求拜访网络中AF的业务时,归属网络的PCRF根据UE的签约信息,拜访网络PCRF根据拜访网络的能力和本地策略,分别决定是否允许该UE使用该业务,如果归属网络的PCRF和拜访网络PCRP都允许,再确定相应的策略及计费规则并进行策略及计费控制,否则拒绝UE的请求。 When the UE requests the visited network AF service, the home network PCRF based on the subscription information of the UE, the visited network PCRF according to the visited network capabilities and local policy, respectively, determine whether the UE is allowed to use the service, if the PCRF home network and a visited network PCRP allow, and then determine the appropriate policy and charging rules and policy and charging control, or refuse the request of the UE.

如果是在线计费,则拜访网络PCEF通过拜访网络OCS向归属网络OCS 申请计费信用。 If online charging, the PCEF visited network via the visited network to the home network OCS OCS application billing credit.

这种技术方案上的区别,带来了较为明显的有益效果,即因为增加了归属网络和拜访网络的OCS间接口,所以漫游到拜访网络的UE使用拜访网络的AF业务时,拜访网络的OCS可以对该UE进行在线计费,从而简化了策略和计费控制流程,优化了网络性能,提高了网络资源的利用率。 When the difference in this solution brings obvious advantageous effect, i.e. because of increased between home and visited OCS network interface, UE roams to a visited network visited network using the AF service, the network visited OCS available for online charging for the UE, thus simplifying the policy and charging control processes, optimize network performance, improve the utilization of network resources.

通过提出PCRF间接口的具体实现方式及其中传递的信息种类,使方案更具可实施性。 By presenting specific implementations and type information transmission in the interface between the PCRF, so that the program can be implemented more.

通过将PCRF和OCS在同一个网络实体中实现,进一步简化了各网元间的接口。 PCRF and OCS implemented by the same network entity, further simplifying the interface between the network elements.

通过在归属网络PCRF和拜访网络PCRF两层决策,使得在UE接入拜访网络AF的业务时,可以综合考虑UE的签约情况和拜访网络的实际能力以得出是否允许UE接入该业务的决定。 Decisions by the home network and the visited network PCRF PCRF two decisions, such that AF visited network service access the UE, the UE can consider the case and the actual subscription capability of the visited network to obtain access to the UE whether to allow service .
