Description

IMS/PoC系统中群组通信的计费方法 IMS / PoC group communication system, a method of charging

技术领域 FIELD

本发明涉及IP多媒体子系统(IMS)的计费技术,其中特别涉及PoC(Push-to-talk over Cellular)系统中与群组通信相关的计费技术。 The present invention relates to an IP Multimedia Subsystem (IMS) charging technique relates to particular PoC (Push-to-talk over Cellular) system in association with the group communication charging technique.

背景技术 Background technique

蜂窝小区结构是利用有限频率资源来解决大范围地区覆盖和大用户容量通信问题的重大突破,在1979年世界上第一个蜂窝移动通信系统即将出现之际,MacDonald.VH在美国贝尔系统技术杂志上发表了题为“The Cellular Concept”一文,第一次对移动通信的蜂窝小区结构概念、原理和相关的分析,作了较全面的介绍。 Cell structure is the use of limited frequency resources to solve a wide range of large area coverage and user capacity communication problems a major breakthrough, a cellular mobile communication system is about to appear in 1979 on the occasion of the world's first, MacDonald.VH American technology magazine in the Bell System on a speech entitled "the cellular concept" a text, for the first time the concept of cell structure of mobile communication, and the related analysis, made a more comprehensive introduction. 这已经成为现代移动通信系统结构的基础和实现原则。 This has become the basis of the principles of modern architecture and realization of mobile communications.

PoC(Push-to-talk over Cellular)(无线一键通)业务是OMA(Open Mobile Alliance-开放移动互联)提出的一种新型移动通信业务,该业务在手机上实现类似对讲机的功能,PoC手机用户不需拨号只要按下一个专用键就可以和某个人或某个群组进行一对一或一对多的通话。 PoC (Push-to-talk over Cellular) (PoC) service is a new mobile communication service OMA (Open Mobile Alliance- Open Mobile Internet) formulation of a walkie-talkie service implementing similar functions on the phone, the PoC phone users do not need to dial just by pushing a dedicated button you can talk one on one or one to many and a person or a group. 有别于早期基于模拟或电路交换技术的专用PTT(Push-to-talk)无线系统,PoC是作为一种应用业务而建立在IP多媒体子系统(IMS)上的,其基本特点包括:独立于所采用的无线接入技术;基于IP的半双工语音;基于SIP(会话发起协议)的会话控制和基于RTP(实时传输协议)的发言权控制(Floor Control);PoC系统作为IMS网络的应用服务器而建立在IMS核心网的基础上。 Unlike earlier PTT private or switched technology based on analog circuits (Push-to-talk) wireless system, the PoC service as an application and is based on IP Multimedia Subsystem (IMS), the basic features include: independent the employed radio access technology; IP-based half-duplex voice; based on SIP (session initiation protocol) session control based on RTP (real-time transport protocol) control of the floor (Floor control); PoC system applied as an IMS network the server is based on the IMS core network.

当前PoC规范支持一对一PoC会话(1-1 PoC Session)、临时PoC群组会话(Ad-hoc PoC Group Session)、预安排PoC群组会话(Pre-arranged PoC Group Session)及聊天PoC群组会话(Chat PoCGroup Session)。 The current specification supports one PoC PoC session (1-1 PoC Session), temporary PoC group session (Ad-hoc PoC Group Session), pre-arranged PoC group session (Pre-arranged PoC Group Session) and chat PoC group conversation (Chat PoCGroup session). 其中,临时PoC群组会话与一对一PoC会话在PoC会话建立方式上相似,都是通过某PoC用户向其他PoC用户的URI(通用资源标识符)发起会话请求而建立起来的,不同的是一对一PoC会话中某PoC用户仅与另一个PoC用户建立会话,而临时PoC群组会话中某PoC用户同时与多个PoC用户建立会话;预安排PoC群组会话则与聊天PoC群组会话在PoC会话建立方式上相似,都是通过某PoC用户向某PoC群组的URI发起会话请求而建立起来的,不同的是在预安排PoC群组会话中,一旦某预安排PoC群组中的PoC用户向该群组发起通话请求,若该群组会话尚未建立系统将主动向该预安排PoC群组中的所有其他用户发起会话请求,而在聊天PoC群组会话中,该主叫用户仅加入该聊天PoC群组会话而不对该聊天PoC群组中的其他用户发起会话请求。 Which, like the temporary PoC group sessions and one to one PoC session is established PoC session mode, and set up a session is initiated by a request to the other PoC user URI (Universal Resource Identifier) ​​via a PoC user, the difference is establishing a PoC user only one PoC session with another PoC user session, and the provisional PoC group session the PoC user while establishing a session with a plurality of PoC users; pre-arranged PoC group session and a chat PoC group session is in a manner similar to the PoC session establishment, it is built up initiates a session request to a PoC group URI by a PoC user, except that in the pre-arranged PoC group session, once a pre-arranged PoC group in PoC user initiates a call request to the group, if the group session is not yet established the active system to all other users in the pre-arranged PoC group session request is initiated, and in the chat PoC group session, the calling user only was added to the chat PoC group sessions without initiating a session request to the other users in the chat PoC group.

根据OMA规范“Push to talk over Cellular(PoC)-Architecture,Candidate Version 1.0-17 March 2005”及3GPP(第三代合作项目)规范TS23.228 V6.9.0(2005-03),PoC系统结构如图1所示。 According to the OMA specification "Push to talk over Cellular (PoC) -Architecture, Candidate Version 1.0-17 March 2005", and 3GPP (Third Generation Partnership Project) specification TS23.228 V6.9.0 (2005-03), PoC system configuration in FIG. 1 shown in FIG. 图1中P-CSCF(代理呼叫状态控制功能)、I-CSCF(问询呼叫状态控制功能)与S-CSCF(服务呼叫状态控制功能)构成IMS核心(IMS Core),完成IMS基本会话控制、SIP消息路由、业务激发等核心网络功能。 FIG 1 P-CSCF (Proxy Call State Control Function), I-CSCF (Call State Control Function queries) and the S-CSCF (Serving Call State Control Function) constitutes IMS Core (IMS Core), to complete the basic IMS session control, SIP message routing, stimulate business and other core network functions. HSS(归属用户服务器)是用户配置数据库服务器,用于存储用户的位置信息以及用户的各种签约信息等业务数据。 HSS (Home Subscriber Server) is a user profile database server for storing user location information and the user's subscription information, various service data. PoC服务器是PoC业务的IMS应用服务器,完成PoC会话处理、媒体分发、发言权控制、群组会话策略管理等功能;PoC群组通信所需的群组列表数据是以XML(可扩展的标记语言)形式组织并由XDMS(XML文档管理服务器)存储和管理,其中,可供各种OMA应用业务共用的群组列表数据如URI列表等由共享XDMS存储和管理,而PoC业务专用的群组列表数据,包括PoC群组(PoC Groups)和PoC用户访问策略(PoC User Access Policy)等则由PoC XDMS存储和管理。 PoC Server is the PoC service IMS application server, complete PoC session handling, media distribution, floor control, policy management group session; PoC group list data required for group communication based on XML (Extensible Markup Language ) organized by the XDMS (the XML document management server) is stored and managed, wherein OMA application services for a variety of common data group list, such as the shared XDMS other URI-list storage and management, and service-specific PoC group list data, including PoC group (PoC Groups) and PoC user access policy (PoC user access policy) and so on are stored and managed by the PoC XDMS. XDMS除了可以被相应的应用服务器所访问外,也允许PoC用户通过汇聚代理(Aggregation Proxy)访问以进行XML文档的创建、修改、获取或者删除等管理操作。 In addition XDMS can be accessed by the appropriate application server, but also allow PoC users by pooling agent (Aggregation Proxy) access for creating XML documents, modify, delete or get management operations. Presence服务器是Presence业务的应用服务器,可为PoC用户提供其他PoC用户的状态及可用信息。 Presence Presence service server is an application server that provides users of other PoC PoC user status and information available. 与XDMS相关的接口均采用XCAP(XML配置访问协议)协议,PoC服务器、PoC XDMS及共享XDMS与S-CSCF的ISC接口均采用SIP协议,其中PoC XDMS及共享XDMS与S-CSCF的ISC接口用于对群组列表XML文档修改事件的订阅(Subscription)和通知(Notification)。 Associated with the XDMS ports use XCAP (XML Configuration Access Protocol) protocol, the PoC server, the PoC XDMS and shared XDMS and S-CSCF ISC interface adopts the SIP protocol, wherein the PoC XDMS and shared XDMS and S-CSCF ISC interface with Subscribe to the group in the list of XML document modification event (subscription) and notification (notification). 关于SIP和XCAP协议的详细描述,可以分别参考IETF(因特网工程任务组)的规范RFC3261及草案“The ExtensibleMarkup Language(XML)Configuration Access protocol(XCAP)”,J.Rosenberg,Feb.2005,http://www.ietf.org/internet-drafts/draft-ietf-slmple-xcap-06.txt”,关于PoC的详细描述可以参考“http://member.openmobilealliance.org/ftp/Public_documents/POC/Permanent_documents/”所给出的PoC系列规范。 A detailed description of SIP and XCAP protocol, refer to the draft specification RFC3261 and the IETF (Internet Engineering Task Force), respectively, "The ExtensibleMarkup Language (XML) Configuration Access protocol (XCAP)", J.Rosenberg, Feb.2005, http: / /www.ietf.org/internet-drafts/draft-ietf-slmple-xcap-06.txt ", a detailed description PoC can refer to" http://member.openmobilealliance.org/ftp/Public_documents/POC/Permanent_documents/ "given series PoC specification.

PoC服务器在逻辑结构上划分为控制PoC功能和参与PoC功能,一个PoC服务器实体对某个PoC会话而言或者执行参与PoC功能或者控制PoC功能。 PoC server into controlling PoC function and participating PoC function, a PoC server entity in terms of a PoC session, or a Participating PoC function or perform Controlling PoC function in the logical structure. 一个PoC会话的参与者可能连接多个不同的PoC服务器,而各相关PoC服务器所承担的功能是在该PoC会话建立时确定的,并且保持不变化直至该PoC会话全部结束。 Participants in a PoC session may be connected to a plurality of different PoC server, the PoC server and each associated function is undertaken to determine when the PoC session establishment, and remains unchanged until the end of the entire PoC session. 在一对一PoC会话和临时PoC群组会话中,发起会话请求的用户所在的PoC服务器将负责承担控制PoC功能;在预安排PoC群组会话和聊天PoC群组会话中,将PoC群组URI解析为各组成员URI的PoC服务器将负责承担控制PoC功能。 In one PoC session PoC server and temporary PoC group session, initiates a session request of the user is located will be responsible for controlling PoC function; in the pre-arranged PoC group session and a chat PoC group session, the PoC group URI resolves to the members of each group URI of the PoC server will be responsible for controlling PoC function. 在PoC系统中,承担控制PoC功能的PoC服务器将负责相应PoC会话的发言权控制和媒体分发等控制功能,承担参与PoC功能的PoC服务器则负责相应PoC会话的发言权控制消息中继和媒体中继等功能。 In the PoC system, assume the Controlling PoC function of the PoC server will be responsible for floor control and media control function distribution, etc. of the corresponding PoC session, the PoC server bear participating PoC function is responsible for the corresponding PoC session and floor control message relay media following functions. 其中,对预安排PoC群组会话和聊天PoC群组,在送往承担控制PoC功能的PoC服务器和承担参与PoC功能的PoC服务器的初始会话请求中,都将携带相应PoC群组的URI。 Wherein the pre-arranged PoC group and a chat PoC group session, assume the function of Controlling PoC server and the PoC session request to assume the initial participating PoC function of the PoC server, will carry the URI sent in the corresponding PoC group.

根据3GPP(第三代合作项目)的草案TS32.272 V1.0.0(2005-02)“Push-to-talk over Cellular(PoC)charging”及技术报告TR23.979V6.0.0(2004-12)“3GPP enablers for OMA PoC Services”,PoC支持3GPP规范TS32.240及TS32.260所述的非实时离线计费和实时在线计费两种方式。 According to (2005-02) "Push-to-talk over Cellular (PoC) charging" and TR23.979V6.0.0 draft technical report 3GPP (Third Generation Partnership Project) of TS32.272 V1.0.0 (2004-12) "3GPP enablers for OMA PoC Services ", PoC specification 3GPP support non-real-time online and offline charging, charging two ways according to TS32.240 and TS32.260.

在图2所示的PoC计费结构中,在线计费系统(OCS)用于在线实时计费,它与PoC服务器通过Ro接口相连;CDF(计费数据功能)和CGF(计费网关功能)用于离线计费,PoC服务器通过Rf接口向CDF提供有关计费信息并由CDF生成CDR(计费数据记录),CGF则将由CDF通过Ga接口提供的CDR生成CDR文件并最终传输到帐单系统。 PoC charging structure shown in FIG. 2, the online charging system (OCS) for the online real-time charging, which is connected to the PoC server interface via Ro; CDF (Charging Data Function) and the CGF (charging gateway function) for offline charging, PoC server via Rf interface to provide accounting information to the CDF generated by the CDF CDR (charging data record), CGF will eventually transfer to the billing system and the CDF generates the CDR file interface provided by CDR Ga . 其中,所述Ro、Rf接口均采用Diameter协议进行通信。 Wherein said Ro, Rf Diameter protocol interfaces are used to communicate. 为了话费统计、运营商之间的结算等目的,在线计费也允许产生CDR,为此可以在OCS中实现可选的CGF功能。 Calls for statistics, billing and other purposes, online billing between operators also allows the production of CDR, for this purpose can be achieved CGF optional features in OCS.

为了便于对PoC业务进行计费,根据3GPP的草案TS32.272V1.0.0(2005-02)所述的PoC计费原则,PoC业务被分解为早期会话(Early-Session)建立、PoC会话参与、即时个人提醒(Instant personalalert)、PoC话音突发(PoC talk burst)发送与接收及PoC群组公告(PoC group advertisement)等多个可被独立计费的子业务,各子业务的被计费方则可能是PoC会话的参与者、PoC会话发起者、PoC群组所有者、相应子业务的使用者等在PoC会话中扮演不同角色的PoC用户,实际系统中哪种子业务由PoC会话中扮演哪种角色的PoC用户负责付费,可以由OCS(对在线计费的情况)或帐单系统(对离线计费的情况)决定,也可以在PoC服务器中进行预配置。 To facilitate billing of the PoC service, in accordance with (2005-02) PoC charging according to the principles of the draft 3GPP TS32.272V1.0.0, PoC traffic is divided into early session (Early-Session) establishing, PoC session participant, instant personal reminders (Instant personalalert), PoC talk spurt (PoC talk burst) to the transmitting and receiving PoC group announcement (PoC group advertisement) and the like may be a plurality of separate sub-service billing, respective sub-service to be billed for the party participants may be PoC session, PoC session initiator, PoC group owners, users and other corresponding sub-service play different roles in the PoC user PoC session, a practical system which child business which played a PoC session PoC user is responsible for paying the kind of role can be determined by the OCS (online charging of the situation) or billing system (case of offline charging), it can also be pre-configured in the PoC server. 参考OMA的草案“Push to Talk Over Cellular 2 Requirements,Version 2.0-17March 2005”,随着PoC业务能力的增加,如支持图象、视频、多媒体等媒体类型及各媒体分量独立的发言权控制等,在新的版本中PoC业务将出现更多的可被独立计费的子业务以及新的被计费方类型,但上述计费原则仍是相同的。 Reference OMA draft of "Push to Talk Over Cellular 2 Requirements, Version 2.0-17March 2005", with the increase in the PoC service capabilities, such as support for images, video, multimedia and other types of media and all media components separate floor control, in the new version will be more PoC service can be independent sub-billing and new service to be billed for the type of party, but a charge is still the principle is the same.

根据3GPP规范TS32.299 V6.2.0(2005-03)、TS32.260 V6.1.0(2005-03)及草案TS32.272 V1.0.0(2005-02),对离线计费的情况,PoC服务器产生的计费信息利用Diameter基础协议(RFC3588)的计费请求消息“Accounting-Request”(ACR)及其应答消息“Accounting-Answer”(ACA)传送到CDF;对在线计费的情况,PoC服务器产生的计费信息则利用Diameter信用控制应用协议(参见http://www.ietf.org/internet-drafts/draft-ietf-aaa-diameter-cc-06.txt)的信用控制请求消息“Credit-Control-Request”(CCR)和其应答消息“Credit-Control-Answer”(CCA)传送到OCS。 TS32.299 V6.2.0 (2005-03), TS32.260 V6.1.0 (2005-03) and Draft TS32.272 V1.0.0 (2005-02), the case of offline charging, PoC server generated according to 3GPP specifications billing information using the billing Diameter base protocol (RFC3588) request message "accounting-request" (ACR) and the answer message "accounting-answer" (ACA) is transmitted to the CDF; the case of online charging, PoC server generates charging information using the Diameter credit control application protocol (see http://www.ietf.org/internet-drafts/draft-ietf-aaa-diameter-cc-06.txt) a credit control request message "credit-control -Request "(CCR), and its answer message" Credit-Control-answer "(CCA) is transmitted to OCS.

在图3和图4所示的ACR和CCR的AVP(属性值对)结构中,ACR的AVP由Diameter基础协议AVP和业务信息AVP组成,CCR的AVP由Diameter基础协议AVP、Diameter信用控制应用协议AVP和业务信息AVP组成,其中,业务信息AVP包括分组交换承载的PS-Information AVP、IMS相关的IMS-Information AVP及PoC业务特有的PoC-Information AVP。 In FIGS. 3 and 4 ACR and the CCR represented AVP (attribute value pair) configuration, ACR AVP in the Diameter base protocol service information AVP and AVP composition, CCR AVP in the Diameter base protocol AVP, Diameter Credit Control Application Protocol AVP and AVP composition service information, wherein the service information comprises a PS-information AVP AVP packet switched bearer, associated with the IMS and IMS-information AVP PoC service specific PoC-information AVP. PoC-Information AVP包括了所有反映PoC特有的计费属性参数以支持按上述原则对PoC业务进行计费,如TS32.272 V1.0.0(2005-02)已定义的“PoC Server Role”、“PoCSession Type”、“PoC Subscriber Session Role”及其它待定义的反映PoC有关子业务计费属性的参数。 PoC-Information AVP includes all reflect billing attribute parameters specific to support the PoC above principles PoC service billing, such as TS32.272 V1.0.0 (2005-02) defined "PoC Server Role", "PoCSession Type "," parameters PoC Subscriber Session Role "and other definitions to be reflected in the relevant sub-PoC service charging property. 其中,“PoC Subscriber SessionRole”即反映了该用户在上述PoC会话中的角色。 Which, "PoC Subscriber SessionRole" That reflects the role of the user in the above PoC session. 离线计费ACR消息和在线计费CCR消息的Diameter基础协议AVP中均包含了AVP“User-Name”,而在线计费CCR消息的Diameter信用控制应用协议AVP中还包含了AVP“Subscription-Id”。 Diameter base protocol messages offline charging and online charging ACR CCR message contains both AVP AVP "User-Name", and the Diameter Credit Control Application Protocol AVP online charging CCR message also contains AVP "Subscription-Id" . 根据3GPP的规范TS32.299 V6.2.0(2005-03)与TS 32.296 V6.0.0(2004-12),所述AVP“User-Name”包含了唯一标识IMS签约用户的私有用户标识(PrivateUser Identity),AVP“Subscription-Id”由AVP“Subscription-Id-Type”和AVP“Subscription-Id-Data”组成,用于标识在线计费中的被计费方。 According to 3GPP specifications TS32.299 V6.2.0 (2005-03) and TS 32.296 V6.0.0 (2004-12), the AVP "User-Name" contains a unique identifier IMS private user identity of the subscriber (PrivateUser Identity) , AVP "Subscription-Id" the AVP "Subscription-Id-Type" and AVP "Subscription-Id-Data", is used for identifying the online charging in the charged party.

在现有的PoC计费技术中,系统基于所采用的PoC各子业务的计费模式、费率等资费标准,对离线计费的情况,帐单系统根据CDR中的用户标识和指示该用户在该PoC会话中的角色等计费相关信息,利用CDR中反映该用户使用PoC有关子业务的详细记录数据即可完成PoC业务话单的批价结算处理;对于在线计费的情况,OCS根据来自Ro接口的CCR消息中AVP“User-Name”所指示的PoC用户在该PoC会话中的角色等计费相关信息,利用该消息中所传送的反映该用户使用PoC有关子业务的详细记录数据,基于“Subscription-Id”所指示的被计费方帐户余额进行实时计费和信用控制。 In the prior art of PoC charging system based on the respective sub-service using a PoC charging model, the standard tariff rates, etc., where for offline charging, the billing system according to the user identifier and indicating that the user of the CDR characters, etc. in this PoC session charging information, the use of CDR data is reflected in the detail record related to the sub-user using PoC service to complete the settlement processing PoC service rating of the bill; in the case of online charging, the OCS according to Ro CCR message from the PoC user interface in AVP "user-Name" indicated by characters, etc. in the PoC session charging information by reflecting the data of the detail record related to the sub-user using PoC service in the message transmitted , real-time billing and credit control based on the charging party account balance "Subscription-Id" indicates.

另一方面,PoC业务的一个显著特点是实现预安排PoC群组、聊天PoC群组等特定群组的通信。 On the other hand, a notable feature of the PoC service is to achieve a pre-arranged PoC group, the chat PoC group communication particular group and the like. 此类特定群组通信主要是针对集团用户或者企业用户,它们往往出于集团业务的需要在其内部或其特定客户群等特定用户群中构建一个或多个PoC群组,对此类PoC群组通信,其费用在一定条件下由相应集团或者企业统一支付是更为常见的用户需求。 Such specific group communication is mainly for business users or user groups, they often need to build our business in one or more PoC group in its interior or specific groups of customers and other specific groups of users, a group out of such PoC group communication, the cost of reunification under certain conditions, payments are more common user requirements by the respective group or enterprise. 这种付费方案将有利于PoC业务经营者开拓集团用户市场并扩大PoC业务量和运营收益,同时该方案还使得集团或者企业用户在保证自身业务有效开展的同时有效避免或减少支付私人性质的个人话费,因此将有利于PoC业务的开展和实施。 This program will help to pay for PoC service operators to open up markets and expand PoC user group business volume and operating income, while the program also allows groups or business users while ensuring the effective implementation of their business effectively prevent or reduce pay for private personal nature calls, therefore will benefit the development and implementation of the PoC service.

但是现有技术在帐单系统/OCS或PoC服务器中根据用户在PoC会话中所担当的角色对PoC各子业务付费方进行固定配置,将难以解决不同群组付费方不同的计费问题。 However, in the prior art billing system / OCS or PoC server based on user role to play in the PoC session in the PoC service for each sub-payer fixed configuration, it will be difficult to solve different problems in different groups paying party billing. 对离线计费的情况虽然可能在后台帐单系统中利用群组信息进行批价处理,但现有技术中帐单系统并不能直接访问PoC XDMS,而PoC XDMS中的群组列表数据也未定义PoC群组成员的付费属性,而且PoC群组的属性包括成员等是允许用户动态修改的,因此难以解决后台帐单系统非实时处理与PoC群组动态变化的问题。 Although the case of offline charging may take advantage of the group in the background billing system rating processing information, but the art billing systems can not directly access the PoC XDMS, and PoC XDMS group list data is also not defined PoC group members pay property, and the property includes a PoC group members, etc. that allows users to dynamically modify, it is difficult to solve the problem of dynamic backend billing system and non-real-time processing PoC group. 同样对在线计费的情况,由于PoC XDMS中的群组列表数据并未定义PoC群组成员的付费属性,因此也较难实现针对不同群组不同计费方的实时计费和信用控制。 Similarly to the case of online charging, since the group list data is not defined in the PoC XDMS PoC group members pay property and, therefore, more difficult to achieve real-time billing and credit control group charging different for different parties.

另外如上所述,PoC群组通信的一个重要应用是面向集团用户或者企业用户,实际中对此类用户运营商往往需要根据集团用户的业务量、用户数、行业特点等制定针对性的资费优惠政策,从而有效发展高端客户以增加运营收入。 Also as mentioned above, an important application of the PoC group communication is for business users or user groups, the actual user of such operators often need to group users based on business volume, number of users, industry characteristics such as the development of targeted tariff concessions policy, so as to effectively develop high-end customers in order to increase operating income. 显然,在PoC群组通信中此类资费优惠政策的制定是针对特定的PoC群组而不是个人用户的,但是,现有PoC计费技术中Ro和Rf接口的Diameter消息中均未携带PoC群组标识的有关信息,因此较难在计费系统中针对特定的群组实施有针对性的资费优惠政策。 Clearly, in PoC group communication in the development of such preferential tariff is for a specific PoC group rather than individual users, but existing PoC charging technology news Diameter Ro and Rf interfaces were not carrying PoC group group identification information, and therefore more difficult to implement in the charging system targeted for a specific group of preferential tariffs.

具体实施方式 detailed description

以下通过结合附图,对本发明的优选实施方式进行描述,应该理解,在这里描述的优选实施方式并不是限制性的说明,本领域技术人员可以根据本发明的原理,对本发明作出各种修改、改进而不会脱离随附权利要求所限定保护范围。 Hereinafter, preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, it should be understood that the preferred embodiments described herein are not limiting description, one skilled in the art may make various modifications of the invention in accordance with principles of the present invention, improvements without departing from the scope of the claims appended hereto.

尽管以下对发明内容的描述主要针对PoC群组通信计费的情况,但是,本发明提出的基本方法和原则,对PoC业务以外的群组通信应用,如IMS会议应用等都是适用的。 While the basic principles of the method and the following description of the invention is mainly for the case where the content of group communication of PoC charging, however, the present invention provides the group communication applications other than the PoC service, such as the IMS session applications it is suitable.

根据本发明,提出了一种对IP多媒体子系统/无线一键通业务(IMS/PoC)系统中群组通信进行计费的方法,其中,PoC服务器通过Ro接口与在线计费系统(OCS)相连用于在线实时计费;PoC服务器通过Rf接口与计费数据功能(CDF)相连,向CDF提供有关计费信息并由CDF生成计费数据记录(CDR)传送给计费网关功能(CGF)并最终传输到帐单系统以用于离线计费;有关PoC群组通信所需的群组列表数据由与PoC服务器相连的XML文档管理服务器(XDMS)存储和管理;以及所述Ro、Rf接口均采用Diameter协议进行通信;所述方法包括:在PoC XDMS中的群组列表数据中增加有关PoC群组成员的付费属性的信息;以及对Rf接口或Ro接口的Diameter协议进行扩展以增加PoC群组标识及该PoC群组中集中被计费方的有关信息。 According to the present invention, a method is proposed for IP Multimedia Subsystem / PoC service (IMS / PoC) group communication method of billing system, wherein, the PoC server via Ro interface with the online charging system (OCS) is connected to real-time charging for online; the PoC server connected via Rf interface with a charging data function (CDF), provide accounting information to the CDF by the CDF generates charging data record (CDR) is transmitted to a charging gateway function (the CGF) and ultimately transmitted to the billing system for offline charging; group communication of PoC group list related data required by the XML document management server connected to the PoC server (the XDMS) storage and management; and the Ro, Rf Interface Diameter protocol are used to communicate; the method comprising: adding information about the PoC group members payment attributes for PoC group list data in the XDMS; and Rf interface to the Diameter protocol, or Ro interface is extended to increase the PoC group the PoC group identity and group information is centralized billing party.

1.PoC XDMS群组列表数据的扩展根据本发明,为了支持增强的PoC群组通信计费功能,在PoCXDMS中的群组列表数据中增加有关PoC群组成员的付费属性的信息,包括但不限于负责支付该群组通信部分或全部费用的集中被计费方、由该集中被计费方为该群组各成员在该PoC群组通信中产生的PoC业务费用所支付的比例、以及该集中被计费方为该群组各成员在该PoC群组通信中所产生的PoC业务费用按此比例进行支付的条件等信息。 1.PoC XDMS extended group list data according to the present invention, in order to support enhanced PoC group communication charging function, the data in the group list is added PoCXDMS PoC group member information on payment attributes, including, but not limited responsible for paying the cost of some or all of the group communication is centralized billing party, that is in the set by a ratio of the group members PoC service charges generated in the PoC group communication party paid billing, and centralized information for the charged party group PoC operating expenses of members of the PoC group communication arising from the payment of this ratio conditions.

由于只有PoC群组所有者允许通过Ut接口对PoC群组XML文件创建、修改、删除等管理操作,因此支付该群组通信费用的集中被计费方只可能是该PoC群组所有者。 Since only the PoC group owner Ut interface allows PoC group XML file is created, modified, deleted by management operations, and therefore pay the cost of group communication is centralized billing party may only be the PoC group owner. PoC群组中除该PoC群组所有者以外的其它成员在该PoC群组通信中所产生的PoC业务费用的部分或全部可由该PoC群组的所有者负责支付。 Part of the PoC group in addition to other members of the PoC group owner in the PoC group communication in PoC service fees generated by the owner or all of the PoC group responsible for the payment. 该PoC群组各成员享有由该PoC群组所有者为其支付部分或全部其在该PoC群组通信中产生的PoC业务费用可能需要满足一定的条件,典型的条件包括但不限于有效时间段、在一定时间内的免费额度等。 The members of the PoC group enjoyed by the owner of the PoC group for PoC pay some or all of its operating expenses generated in the PoC group communication may be required to meet certain conditions, typical conditions include, but are not limited to, the effective period in a certain amount of free time, and so on. 如某公司工作时间是周一至周五的09:30到18:00,则该公司的一个PoC群组即可能在此工作时间内免费,在周一至周五的其它时间为其成员支付一半的在该PoC群组通信中所产生的PoC业务费用,而在周六和周日则完全由各成员个人支付。 If a company working hours are Monday to Friday 09:30 to 18:00, the company is a PoC group that is possible within this time working for free, pay half of its members at other times from Monday to Friday of PoC service costs in the PoC group communication generated, and is fully paid by the individual members on Saturday and Sunday. 另一个例子是规定各成员可享有的在该群组通信中一定时间内的免费额度,某成员一旦在规定时间内在该群组通信中由该群组集中付费方支付的费用超过其免费额度,在此规定时间内该PoC群组所有者将不再为其支付其在该PoC群组通信中所产生的PoC业务费用。 Another example is the provision in the amount of free members can enjoy some time in the group communication, once a member of the prescribed fee in time within the group communication concentrated payers paid by this group exceeds its free quota, During this time provisions of the PoC group owner will no longer pay for its operating expenses PoC arising in the PoC group communications.

根据OMA规范“PoC XDM Specification Candidate Version 1.0-17 March 2005”,用于预安排PoC群组及聊天PoC群组等PoC群组通信的PoC群组由PoC XDMS中的基于“list-service”文档模板的XML文件所描述。 "PoC XDM Specification Candidate Version 1.0-17 March 2005", for the pre-arranged PoC group and a chat PoC group communication or the like according to the OMA PoC group PoC group from the PoC specification based on the XDMS "list-service" document template XML files are described. 在该规范所给出的“list-service”文档的XMLschema的基础上,作为一个示范性非限制性的例子,图5给出了基于本发明的“list-service”文档的XML schema。 On the basis of the specification given XMLschema the "list-service" on the document, as a non-limiting example exemplary, FIG. 5 shows the XML schema based on the "list-service" document of the present invention. 关于XML schema的详细描述,可以由W3C的网址“http://www.w3.org/XML/Schema”获得相关信息。 A detailed description of the XML schema, you can get information from the W3C website "http://www.w3.org/XML/Schema".

图5是基于本发明的一个“list-service”文档XML schema的例子,其中以图5-I、5-II的形式示出了所述“list-service”文档的XMLschema。 FIG 5 is an example of the present invention, a "list-service" document based on XML schema, which in FIG. 5-I, 5-II form shows XMLschema the "list-service" document. 在图5所示的“list-service”文档的XML schema中,阴影所示为基于本发明而增加的部分,其它为OMA规范所给出的部分。 In FIG XML schema "list-service" document shown in Figure 5, the present invention is based on the increase of the portion shown hatched, the other part of the OMA specification given. 其中,<list-service>根元素可包含<is-charged-party>元素,该元素取值为布尔类型,用于指示该群组的所有者是否为集中支付该群组通信费用的被计费方。 Wherein, & lt; list-service & gt; root element may comprise & lt; is-charged-party & gt; element, which value is a Boolean that indicates whether the owner of the group is centralized payment of the group communication charges are billing party. <list-service>根元素还可包含<charging-rule>元素,用于指示PoC群组成员的付费规则,每个<charging-rule>元素可包含<discount>、<expire-time>、<discount-condition>等子元素,其中子元素<discount>取值为0-100的整数,用于指示由该PoC群组的所有者为该PoC群组成员在该PoC群组通信中产生的PoC业务费用所支付的百分比,100%表示对该PoC群组成员免费,为零则表示该该PoC群组的所有者不负责支付该PoC群组成员在该PoC群组通信中产生的PoC业务费用而由该PoC群组成员个人支付;<expire-time>用于指示该付费规则的有效期,在子元素<expire-time>所表示的时间之后该付费规则失效;子元素<discount-condition>则给出了该PoC群组各成员享有按子元素<discount>所给出的比例由该PoC群组所有者为其支付其在该PoC群组通信中产生的PoC业务费用需满足的条件 & Lt; list-service & gt; root element may further comprise & lt; charging-rule & gt; element, for indicating the PoC group members pay rules, each & lt; charging-rule & gt; element may comprise & lt; discount & gt;, & lt; expire- time & gt;, & lt; discount-condition & gt; and other sub-elements, wherein the sub-element & lt; discount & gt; value is an integer from 0 to 100, for indicating the owner of the PoC group for PoC group member in the PoC group the percentage of operating expenses PoC group communication generated by the payment of 100% indicates the PoC group members free of charge, zero, it means that the owner of the PoC group is not responsible for paying the PoC group member in the PoC group communication PoC service costs arising and paid by the PoC group members personally; & lt; expire-time & gt; for the period indicate that the pay rule in the sub-element & lt; expire-time & gt; the payment rules fail after the time indicated; child element & lt; discount-condition & gt; is given of the members of the PoC group sub-elements according to Related & lt; discount & gt; ratio given by the PoC group owner for payment which is produced in the PoC group communication conditions PoC service costs to be met 即由<valid-time>与<valid-day>子元素所给出的一天中适用的时间段和一周中适用的日期。 I.e. a & lt; valid-time & gt; and & lt; valid-day & gt; subelement given day of the week and time period of the applicable date applicable thereto.

尽管图5所示的例子中PoC群组成员的付费规则是针对群组中所有成员的,但是本发明也允许对群组中的各成员分别指定付费规则,或者是将总的付费规则作为缺省项而针对某些成员指定特有的付费规则等等。 Although the example shown in FIG. 5 charge rules for PoC group members are all members of the group, but the present invention also allows each member of the group specified in the rule are paid, or a total lack of payment rules provincial items designated specific pay rules, and so for some members. 另外,除了对群组各成员在该群组通信中所产生的PoC业务费用指定付费规则外,根据本发明,也可以分别对群组各成员在该群组通信中所产生的PoC业务的各个子业务或子业务组合指定相应的付费规则。 In addition to the specific payment rules PoC service costs of the members of the group in the group generated in the outer communication, according to the present invention, it may be separately for each member of the group in the group communication traffic generated in respective PoC sub-sub-business or business combination specify the payment rules. 尽管还可能存在其它的付费规则配置方案,但是,包括上述方案在内的所有可能的实现方案均在本发明所提出的方法和原则之内。 While there may be others paid rule configuration scheme, however, it includes all possible implementations, including the above-described embodiment are within the principle and the method proposed by the present invention.

2.离线计费对增强PoC群组通信计费功能的支持根据本发明,为支持增强的PoC群组通信计费功能,对离线计费的情况,在现有Diameter协议中增加用于描述为AVP“User-Name”所指示的用户承担部分或全部费用的其他被计费方标识的AVP,以及所述其他被计费方为该用户在此呼叫记录内所产生的费用支付的比例的AVP,同时离线计费系统所产生的CDR中也记录所述其他被计费方标识和其费用支付比例,这样,后台帐务系统可利用这些增加的信息对相应的被计费方进行批价结算处理。 2. enhanced support offline charging PoC group communication charging function according to the present invention, is enhanced to support group communication of PoC charging function, the case of offline charging, the existing Diameter protocol is used to describe the increase other charged party identified AVP user AVP "user-Name" indicated bear some or all of the costs, and the other ratios being charged party fees paid for the user in the call record generated AVP while offline charging CDR generated by the system is also recorded in the charged party identification and other fees paid their proportions, so that background accounting system may utilize these additional rating information corresponding billing is charged party deal with.

作为一个示范性非限制性的例子,在Diameter计费协议的AVP结构中,增加一个可选的允许出现多次的类型为“Grouped”的AVP“Charged-Party-List”,该AVP进一步由类型为“UTF8String”的AVP“Charged-Party-ID”和类型为“Unsigned32”的AVP“Charged-Percentage”组成,如下所示(其中TBD表示数值待定):Charged-Party-List::=<AVP Header:TBD> As a non-limiting example exemplary, AVP in Diameter charging protocol structure, increasing an optional type allows for multiple "Grouped" the AVP appears "Charged-Party-List", which is further from the Type AVP is "UTF8String" the AVP "Charged-Party-ID" and type "Unsigned32" the AVP "Charged-Percentage", as shown below (where a numerical value TBD TBD): Charged-Party-List :: = & lt; AVP Header: TBD & gt;

{Charged-Party-ID}{Charged-Percentage}其中,AVP“Charged-Party-ID”对应为AVP“User-Name”所指示的用户承担部分或全部费用的被计费方的用户标识,AVP“Charged-Percentage”则给出了相应被计费方为该用户在此呼叫记录内所产生的费用支付的比例。 {Charged-Party-ID} {Charged-Percentage} where, AVP "Charged-Party-ID" corresponding to assume some or all of the cost of the user is instructed AVP "User-Name" is the user ID of the charged party, AVP " Charged-Percentage "is given by the ratio of the respective charging fees paid by the user for the call records generated.

利用上述协议和计费系统功能的扩展,对PoC离线计费的情况,在PoC服务器与CDF的Rf接口的Diameter消息中使用本发明提出的用于描述为AVP“User-Name”所指示的PoC用户承担部分或全部PoC业务费用的计费方标识及其费用支付比例的AVP,其中,计费方包括AVP“User-Name”所指示的PoC用户自身以及为在该PoC用户所在的PoC群组中负责集中支付该PoC群组通信部分或全部PoC业务费用的被计费方,而各被计费方所负责的费用支付比例由PoC服务器从PoC XDMS所存贮的PoC群组XML文档中获得,其中PoC群组XML文档应支持本发明所述的对PoC群组成员付费属性等有关信息的扩展定义。 Using the extended protocol system and billing functions, the situation PoC offline charging, the proposed use of PoC as used to describe the present invention AVP "User-Name" indicated by a Diameter Rf interface to the PoC server message with the CDF charged party identification and pay the fee ratio AVP user assumes the cost of some or all of the PoC service, wherein, the PoC user billing party includes AVP "user-Name" is indicated PoC group itself and the user's PoC is responsible for the centralized payment PoC group communication part or all of the PoC service fee is charged party, to pay the proportion of the cost of each party being responsible for billing by the PoC server from the PoC XDMS PoC group XML documents stored in get which PoC group XML documents should support the expansion of the definition of the relevant information such as PoC group members pay property according to the present invention.

3.在线计费对增强PoC群组通信计费功能的支持根据本发明,为支持增强的PoC群组通信计费功能,对在线计费的情况,在现有Diameter协议中增加用于描述为AVP“User-Name”所指示的用户承担部分或全部费用的其他被计费方标识的AVP,以及所述其他被计费方为该用户在此呼叫记录内所产生的费用支付的比例的AVP。 3. The enhanced support for online charging PoC group communication charging function according to the present invention, is enhanced to support group communication of PoC charging function, the case of online charging, an increase in the existing Diameter protocol as described for other charged party identified AVP user AVP "user-Name" indicated bear some or all of the costs, and the other ratios being charged party fees paid for the user in the call record generated AVP . 当一个信用控制请求消息指定了多个被计费方及其负责的费用支付比例时,OCS将按照各被计费方负责的费用支付比例对其进行实时计费,而任一被计费方帐户余额不足都将导致业务请求信用认证的失败。 When a credit control request message specifies a number of payout percentage fee is charged party and responsible, OCS will be paid in proportion to the cost of each party is responsible for billing its real-time billing, and either party to be billed account balance will result in insufficient credit certification service request failed.

根据3GPP的草案TS32.272 V1.0.0(2005-02)与IETF的Diameter信用控制应用协议草案(参见http://www.ietf.org/internet-drafts/draft-ietf-aaa-diameter-cc-06.txt),在线计费中Ro接口Diameter消息的AVP“Subscription-Id”为“Multiple-grouped”类型,即允许同时提供多种签约用户标识。 The draft draft Diameter Credit Control Application protocol of 3GPP TS32.272 V1.0.0 (2005-02) with the IETF (see http://www.ietf.org/internet-drafts/draft-ietf-aaa-diameter-cc- 06.txt), the Ro interface for online charging Diameter message AVP "Subscription-Id" is a "multiple-grouped" type, i.e., while allowing a variety of subscriber identity. 但是,当前Diameter信用控制应用协议草案并未说明所述AVP“Subscription-Id”所提供的多种签约用户标识是否属于同一用户,而现有技术并未指定若存在多个被计费方他们应承担费用的比例关系,因此实际上在现有技术下难以通过所述AVP “Subscription-Id”同时指定多个被计费方进行实时计费和信用控制。 However, the current draft Diameter Credit Control Application protocol does not specify the plurality of AVP "Subscription-Id" provided by the subscriber identification belong to the same user, while the prior art does not specify if there are a plurality of them to be charged party bear the cost of a proportional relationship, so it is difficult to actually specify the prior art a plurality of real-time billing and credit control through the charged party AVP "Subscription-Id".

因此,一个优选方案是对现有Diameter信用控制应用协议AVP“Subscription-Id”进行扩展,即在AVP“Subscription-Id”包括AVP“Subscription-Id-Type”和AVP“Subscription-Id-Data”的基础上,在该AVP中增加描述该AVP所指定的被计费方为AVP“User-Name”所指示的用户在此呼叫记录内的费用支付的比例的AVP,并允许用多个AVP“Subscription-Id”指示多个不同的被计费方。 Thus, a preferred embodiment is a conventional Diameter Credit Control Application Protocol AVP "Subscription-Id" expanded, i.e. AVP "Subscription-Id" includes AVP "Subscription-Id-Type" and AVP "Subscription-Id-Data" in based on the increase of the percentage of users described AVP charged party is designated as AVP "user-Name" indicated in the cost of the call record in the payment AVP, AVP, and allows a plurality of AVP "Subscription -Id "is indicative of a plurality of different charged party. 作为一个示范性非限制性的例子,所述AVP“Subscription-Id”定义扩展如下(其中TBD表示数值待定):Subscription-ID::=<AVP Header:TBD> As a non-limiting example exemplary, the AVP "Subscription-Id" is defined as extensions (where a numerical value TBD TBD): Subscription-ID :: = & lt; AVP Header: TBD & gt;

{Subscription-Id-Type}{Subscription-Id-Data}[Charged-Percentage]其中,类型为“Unsigned32”的“Charged-Percentage”为本发明扩展的AVP,用于描述AVP“Subscription-Id-Data”所指定的被计费方在此呼叫记录内为AVP“User-Name”所指示的用户承担费用的比例。 {Subscription-Id-Type} {Subscription-Id-Data} [Charged-Percentage] wherein, type "Unsigned32" the "Charged-Percentage" extended AVP in the present invention, for describing AVP "Subscription-Id-Data" charged party is specified in the call record for the user's expense ratio AVP "user-Name" indicated.

利用上述协议和计费系统功能的扩展,对PoC在线计费的情况,在PoC服务器与OCS的Ro接口的Diameter消息中使用上述对AVP“Subscription-Id”的扩展定义。 Using the extended protocol function and billing systems, online charging PoC situation, using the definition of the extended AVP "Subscription-Id" is a Diameter Ro interface to the PoC server message with the OCS. 为此,可利用AVP“Subscription-Id”同时指定两个被计费方及各自所承担的PoC业务费用比例,其中,一个被计费方是AVP“User-Name”所指示的PoC用户,另一个被计费方是在AVP“User-Name”所指示的PoC用户所在的PoC群组中负责集中支付该PoC群组通信部分或全部PoC业务费用的被计费方,该被计费方以其负责的费用支付比例由PoC服务器从PoC XDMS所存贮的PoC群组XML文档中获得,其中PoC群组XML文档应支持本发明所述的对PoC群组成员付费属性等有关信息的扩展定义。 For such purposes the AVP "Subscription-Id" specify the two parties and the ratio of charging PoC service costs borne by each of which a PoC user is charged party is AVP "User-Name" indicated by the other is a billing party is responsible for the centralized payment PoC group communication part or all of the PoC service costs PoC group PoC user AVP "user-Name" indicated where the party to be billed for the party to be billed the proportion of costs paid by the responsible PoC server from the PoC XDMS the stored PoC group XML document obtained, which PoC group XML documents should support the expansion of the definition of pay-related information on properties such as PoC group members according to the present invention .

4.针对特定群组的资费控制如前所述,对PoC业务等群组通信应用,现有计费技术中Ro和Rf接口的Diameter消息中均未携带群组标识的有关信息,因此较难在计费系统中针对特定的群组实施有针对性的资费策略。 4. As described above the control rates for a particular group, the group communication of PoC service applications, etc., the prior art Diameter charging message in the Ro and Rf interface carries no information about the group identifier, and therefore more difficult to in the charging system of tariff implement targeted strategies for specific groups. 因此根据本发明,对PoC业务等群组通信应用,可以在现有Diameter协议中增加用于标识AVP“User-Name”所指示的用户所在的群组的AVP(对离线计费该AVP所指示的群组标识还将被记录在CDR中),从而便于计费系统按照群组标识针对特定的群组实施有针对性的资费策略。 According to the invention, a service like PoC group communication applications, may be added AVP group of the user for identifying the AVP "User-Name" indicated in the prior Diameter protocol (offline charging for the AVP indicated the group identifier is also recorded in the CDR), thereby facilitating the charging system according to a targeted group identifier embodiment tariff policy for a particular group.

对PoC业务计费的情况,一个优选的非限制性的例子是在图3及图4所示的Diameter消息的“PoC-Information”部分增加一个可选的类型为“Unsigned32”的“PoC-Group-ID”,用于标识AVP“User-Name”所指示的PoC用户所在的PoC群组,它包含了该PoC群组的URI,即该PoC群组在IMS系统中的公共业务标识(PublicService Identity)。 The case where charging PoC service, a preferred non-limiting example in FIGS. 3 and 4 "PoC-Information" Diameter message is shown an optional part of the increase of type "Unsigned32" the "PoC-Group -ID ", used to identify the AVP" PoC group PoC user user-Name "is located as indicated, which contains the URI of the PoC group, i.e. the PoC group public service identity in the IMS system (PublicService identity ). 利用该AVP给出的PoC群组的公共业务标识,计费系统即可针对该PoC群组实施有针对性的资费策略。 The AVP PoC group using the given Public Service Identity, charging system can be implemented for the PoC group targeted pricing strategies.

5.基于本发明的PoC群组通信计费方法由于某PoC群组中负责支付该PoC群组通信部分或全部费用的集中被计费方(即该PoC群组所有者),与某享有由该集中被计费方为其支付部分或全部其在该PoC群组中的PoC业务费用的该PoC群组成员可能分别采用不同的计费方式,因此以下针对可能采用的计费方式的组合情况,利用上述PoC计费系统结构中相应接口协议的扩展,对本发明所提出的增强的PoC群组通信计费方法作进一步的描述。 5. The group communication of PoC charging method according to the present invention, because a PoC group based on the group communication of PoC responsible for paying the full cost of some or concentrate is charged party (i.e. the PoC group owner), and enjoyed by a the members of the PoC group is focused on its pay part or all of its operating costs in the PoC PoC group are charging party may adopt different accounting methods, the following combinations of billing for the possible adoption of , the corresponding interface protocol using the extended configuration the above described PoC charging system, enhancement of group communication of PoC charging method proposed by the present invention will be further described.

对集中被计费方(即PoC群组所有者)采用离线计费方式而PoC群组成员采用在线计费方式的情况,根据本发明,利用上述PoC计费系统结构中相应接口协议的扩展,PoC服务器将同时向Ro接口和Rf接口传送该PoC群组成员的PoC业务呼叫记录数据,其中,送往OCS和CDF的该PoC群组成员的PoC业务呼叫记录数据反映的是相同的PoC业务呼叫状况参数,但送往OCS的Diameter消息中代表被计费方的AVP“Subscription-Id”只有一项,该AVP指示的被计费方就是AVP“User-Name”所指示的该PoC用户,而该AVP中的AVP“Charged-Percentage”应指示该PoC用户所承担的在此呼叫记录内的费用支付比例。 Centralized billing for the party (i.e., PoC group owner) manner using offline charging PoC group member in the case of using the online charging mode, according to the present invention, the above described PoC charging system using the extended configuration corresponding interface protocol, PoC server will Rf interface to the Ro interface, and transmits the PoC group members of the PoC service call data records, wherein, sent to the OCS and CDF PoC group members of the PoC service call record data reflect the same PoC service call condition parameter, but the Diameter message sent to the OCS represents only one, the PoC user is the party to be billed AVP "user-Name" indicated by the indication AVP AVP party billing "Subscription-Id", and the AVP in the AVP "Charged-Percentage" should indicate that PoC users to pay the proportion of costs borne in the call record. 而送往CDF的Diameter消息中应包括两项AVP“Charged-Party-List”,其中一项中的AVP“Charged-Party-ID”指示在AVP“User-Name”所指示的PoC用户所在的PoC群组中负责集中支付该PoC群组通信部分或全部PoC业务费用的集中被计费方(即为该PoC群组所有者),该项中的AVP“Charged-Percentage”则为该集中被计费方所承担的对该PoC用户在此呼叫记录内费用的支付比例;另一项中的AVP“Charged-Party-ID”即指示AVP“User-Name”所指示的该PoC用户,但是该项中的AVP“Charged-Percentage”的值置为零。 Diameter messages sent to the CDF should include two AVP "Charged-Party-List", wherein one of the AVP "Charged-Party-ID" indicating the PoC PoC user AVP "User-Name" is located as indicated the group is responsible for centralized payment PoC group communication part or all of the cost of centralized PoC service is charged party (ie the PoC group owner), that the AVP "Charged-Percentage" was the focus be counted costs borne by the parties in proportion PoC users pay the cost of the call in the record; another in the AVP "Charged-Party-ID" that indicates that the PoC user AVP "user-Name" indicated, but the the AVP "Charged-Percentage" value zero. 在后台帐单系统进行话单批价处理时,若发现某用户的CDR中包括显式地指示该用户的费用支付比例为零的话单,将不对该用户收取该CDR所导致的费用。 Single rating processing carried out in the background, then billing system, if found to comprise the CDR of a user to explicitly indicate the proportion of the user fees paid zero CDR, the CDR will not be charged to the user caused.

对于集中被计费方(即PoC群组所有者)采用在线计费方式而PoC群组成员采用离线计费方式的情况,根据本发明,利用上述PoC计费系统结构中相应接口协议的扩展,PoC服务器将同时向Ro接口和Rf接口传送该PoC群组成员的PoC业务呼叫记录数据,其中,送往OCS和CDF的该PoC群组成员的PoC业务呼叫记录数据反映的是相同的PoC业务呼叫状况参数,但送往OCS的Diameter消息中代表被计费方的AVP“Subscription-Id”只有一项,该AVP指示的被计费方就是在AVP“User-Name”所指示的PoC用户所在的PoC群组中负责集中支付该PoC群组通信部分或全部PoC业务费用的集中被计费方(即为该PoC群组所有者),而该AVP中的AVP“Charged-Percentage”应指示该集中被计费方在此呼叫记录内的费用支付比例。 Centralized billing for the party (i.e., PoC group owner) manner using online charging PoC group member in the case of using an offline charging mode, according to the present invention, the above described PoC charging system using the extended configuration corresponding interface protocol, PoC server will Rf interface to the Ro interface, and transmits the PoC group members of the PoC service call data records, wherein, sent to the OCS and CDF PoC group members of the PoC service call record data reflect the same PoC service call condition parameter, the message sent to the OCS a Diameter AVP represents the charged party "Subscription-Id" is only one, indicating that AVP is where the party to be billed for the PoC user AVP "user-Name" indicated by the PoC group is responsible for the centralized payment PoC group communication part or all of the centralized PoC service fee is charged party (ie the PoC group owner), and the AVP in the AVP "Charged-Percentage" indicates that the focus should be fee is paid pro-rated side in the call record. 另一方面,送往CDF的Diameter消息只需包括一项AVP“Charged-Party-List”,该AVP中的AVP“Charged-Party-ID”指示的被计费方就是AVP“User-Name”所指示的该PoC用户,而该AVP中的AVP“Charged-Percentage”应指示该PoC用户所承担的在此呼叫记录内的费用支付比例。 On the other hand, sent to the CDF comprises a Diameter message only AVP "Charged-Party-List", the AVP is indicated in the AVP "Charged-Party-ID" is the party to be billed for AVP "User-Name" is the PoC user instructions, and in the AVP AVP "Charged-percentage" should indicate the proportion of fees paid in this call records of the PoC user undertaken. 在后台帐单系统进行话单批价处理时,若发现某用户的CDR中包括显式地给出了该用户费用支付比例的话单,将按此比例对该用户收取相应比例的话费。 Single rating processing carried out in the background, then billing system, if found to comprise the CDR of a user explicitly gives the user the fees paid phone bill ratio, this ratio will be charged to the user calls the appropriate proportions.
