Description

通过分组域为电路域用户提供业务的方法技术领域本发明涉及分组域网络与电路域网络融合的方法,特别涉及通过分组域为电路域用户提供业务的方法。 TECHNICAL FIELD The service provided by the CS user packet domain present invention relates to a circuit domain network and a packet domain network convergence, and more particularly to method for providing a packet service domain through the CS user. 背景技术光通信技术和宽带网际协议(Internet Protocol,简称"IP")冲支术的迅猛发展,使得通信主千网络已经具备了强大的应用支撑能力,带宽已经不再是运营商开展业务的主要困难。 BACKGROUND optical communication technology and broadband Internet Protocol (Internet Protocol, referred to as "IP") support the rapid development of punching technique, making communications backbones network already has a strong ability to support applications, the bandwidth is no longer the major carriers doing business difficult. 但从全球电信市场的发展来看,话音和数据业务市场日益趋于饱和,导致运营商开始面临业务增长逐年减少、客户越来越难发展的困境。 But from the point of view of the development of the global telecommunications market, voice and data services market increasingly saturated, resulting in operators facing business growth began to decline every year, more and more difficult predicament customer development. 因此,无论是新兴运营商还是传统运营商都在寻找新的市场机遇和商业模式,从而为其创造新的业务增长点和吸引更多的潜在用户。 Therefore, whether new operators or traditional operators are looking for new market opportunities and business models, and thus for the creation of new business growth and attract more potential users. 公用电话网络由于其电路交换(Circuit Switching,简称"CS")的局限性,限制了其业务多样性的发展,对于用户移动业务、个性化业务和多媒体业务方面的需求,公用电话网络基本无法满足。 Public telephone networks due to the limitations of its circuit-switched (Circuit Switching, referred to as "CS"), limiting the diversity of its business development for mobile business users, personalized services and multimedia business needs of the public telephone network can not meet the basic . 同时,计算机技术和网络技术的革新改变了用户对业务的需求,仅仅是公用电话网或者因特网都不能很好地满足用户对话音、数据、图像的综合需求。 At the same time, computer technology and network technology innovation has changed the needs of users of services, only the public telephone network or the Internet can not satisfy user demand for integrated voice, data and images. 运营商需要一个基于下一代网络架构、提供新一代多媒体业务的解决方案,以创造新的业务增长点。 Operators need a next-generation network architecture to provide next-generation solutions for multimedia services, to create new business growth. 而现有的固网电路域用户通过数字程控交换机和智能网为其提供各种基于公共电话交换网(Public Switched Telephone Network, "PSTN")或综合业务数据网(Integrated Services Digital Network,简称"ISDN")的业务和智能业务。 The existing fixed network CS user through digital program-controlled switches and intelligent network to provide all kinds based public switched telephone network (Public Switched Telephone Network, "PSTN") or an integrated services digital network (Integrated Services Digital Network, referred to as "ISDN ") business and business intelligence. 一方面,由于呼叫控制和业务控制的紧密结合,使业务部署速度较慢、成本较高;另一方面,数字程控交换机和智能网只能提供单纯的电 On the one hand, due to the close connection with call control and service control, service deployment so slow, high cost; on the other hand, digital program-controlled switches and intelligent network can only provide a simple electrical

路域业务,用户的人机交互方式单一,业务体验性较差,用户使用业务的积极性不高,不利于业务的推广。 Road business domain, a single user human-computer interaction, poor service experience, business users are not enthusiastic, is not conducive to the promotion of business. 随着个人移动通信网络的迅猛发展,移动网络逐渐壮大,以及IP网络最终一统天下的背景下,固网下一代网络(Next Generation Networks,简称"NGN")的发展趋势必然是与多种网络融合,比如分组域与电路域的融合, 移动网和固网的融合等。 With the rapid development under the personal mobile communication networks, mobile networks grew, and IP network will eventually dominate the world background, the development trend of fixed-line Next Generation Network (Next Generation Networks, referred to as "NGN") must be the integration with a variety of network , such as fusion domain and packet domain circuit, and the like and fixed-mobile convergence of. 分组域和电路域融合是当前研究热点之一,其中第三代移动通信合作伙伴项目(3rd Generation Partnership Project,简称"3GPP") 在R5/R6标准提出的基于IP的多媒体子系统(IP based Multimedia Subsystem, 简称"IMS")即专门为下一代全IP的多媒体移动网络设计的系统,着眼于用IP网络承载移动多媒体业务,使运营商和终端用户从多媒体服务的革新中获取更快速、更灵活的应用,从而为运营商增加收入、创造利润。 Packet domain or the circuit domain fusion is one of research focus, wherein the third generation mobile communication Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") in the R5 / R6 standard proposed IP-based multimedia subsystem (IP based Multimedia Subsystem, referred to as "IMS") that is specifically designed for next-generation all-IP mobile multimedia network design system, focusing on carrying mobile multimedia services using IP network, allowing operators and end users get from innovative multimedia services in a faster, more flexible applications, thereby increasing revenue for operators, to create profits. IMS是3G移动网实现分组话音和分组数据,提供统一的多媒体业务和应用的目标网络。 IMS is a 3G mobile network implementing the packet voice and packet data, the target network to provide uniform multimedia services and applications. 由于市场竟争的日趋激烈,现有的电路交换系统将被淘汰, 取而代之的是开放、扩展性好、购置和维护成本也更加低廉的基于IP的硬件系统。 Because of the increasingly fierce market competition, the existing circuit-switched system will be phased out and replaced by an open, scalable, acquisition and maintenance costs more affordable IP-based hardware systems. 3GPP系统于是开始逐渐转向一种全部基于IP的核心网络。 3GPP system then gradually move to a full IP-based core network. 3GPP规」 范也越来越突出了IP架构的重要性并引入了IMS这一概念, 一是希望通过IP的形式提供传统的电路交换服务(如语音服务),二是希望通过这个子系统实现向用户提供的所有多媒体服务。 3GPP regulation "Fan also increasingly highlighted the importance of IP infrastructure and introduces the concept of IMS, one hopes to provide traditional circuit-switched services (such as voice service) in the form of IP, the second is hope to achieve through this subsystem All multimedia services to users. IMS是对分组交换域(Packet Switching,简称"PS":)核心网的一个扩展,旨在独立于PS核心网。 IMS is a packet switched domain (Packet Switching, referred to as an extension "PS" :) core network, designed independently of the PS core network. 采用IP分组域作为其控制信令和媒体传输的承载通道,采用会话发起协议(Session Initiation Protocol,简称"SIP")协议作为呼叫控制信令,建立、 保持和终止语音及多媒体进程,实现了业务管理、会话控制及承载接入的三者分离。 Using the IP packet domain as control signaling and media transmission bearer channel using a session initiation protocol (Session Initiation Protocol, referred to as "SIP") as a call control signaling protocol to establish, maintain and terminate the voice and multimedia processes, to achieve the business three management, session control and bearer access separated. 下面给出IMS多媒体话务的几个实例:1.某个用户在接听一路电话时, 又收到另一个打进来的IP可视电话,这个用户决定不接这个可视电话,而是 IMS multimedia traffic gives a few examples of the following: 1. a user when you answer the phone all the way, and receive another incoming IP video phone, the user decides to not answer the videophone, but

把它转往一个留言系统。 It transferred to a voice mail system. 随后,他将会收到一个在其邮箱中有一个视频消息的通知。 Then, he will receive a video message in their mailbox notification. 2.某个用户在接听一路电话时,又收到另一个打进来的IP可视电话,这个用户决定接听这个新的电话,不过他希望自己可以在两路电话间进行切换。 2. When a user all the way to answer the phone, and receive another incoming IP video phone, the user decides to answer the new phone, but he hopes he can switch between the two calls. 3.莱个用户没在接听任何电话,他在修改自己的用户设置文件以将那些所有优先级不高和自己不认识的人的来电都转往别处。 3. Lay the users did not receive any calls, he modify their own user settings file to all of those who are not high priority and they do not know calls are transferred elsewhere. 不过,在这种情况下这个用户仍能收到所有的电子邮件和文本信息,无i仑这些邮件和信息是谁发给他的。 However, in this case the user can still receive all e-mail and text messages, no i Lun these messages and information who had sent him. 图l示出了IMS的框架结构及功能实体。 Figure l shows a frame structure and IMS functional entities. 3GPP定义的IMS的框架结构包括呼叫会话控制功能(Call Session Control Function,简称"CSCF")、 媒体网关控制功能(Media Gateway Control Function,简称"MGCF" ) 、 IMS 媒体网关(IMS - Media GateWay,简称"IMS-MGW")、多媒体资源功能控制器(Multimedia Resource Function Controller,简称"MRFC")、多媒体资源功能处理器(Multimedia Resource Function Processor,简称"MRFP")、 出口网关控制功能(Breakout Gateway Control Function,简称"BGCF"), 及IMS应用服务器(Application Server,简称"AS")和归属用户服务器(Home Subscriber Server,简称"HSS")等功能实体。 Defined by 3GPP IMS frame structure comprises a call session control function (Call Session Control Function, referred to as "CSCF"), media gateway control function (Media Gateway Control Function, referred to as "MGCF"), IMS Media Gateway (IMS - Media GateWay, Acronym "IMS-MGW"), multimedia resource function controller (multimedia resource function controller, abbreviated "MRFC"), multimedia resource function processor (multimedia resource function processor, referred to as "MRFP"), Breakout gateway control function (Breakout gateway control function , referred to as "BGCF"), and IMS application server (application server, referred to as "AS") and home subscriber server (Home Subscriber server, referred to as "HSS") and other functional entities. 其中CSCF是整个网络的核心,支持SIP协议处理SIP会话,又分为询问CSCF( Interrogatmg-CSCF,简称"I-CSCF")和服务CSCF( Serving-CSCF, 简称"S-CSCF")。 CSCF which is the core of the network, supports SIP protocol processing SIP session, divided into asking CSCF (Interrogatmg-CSCF, referred to as "I-CSCF") and services CSCF (Serving-CSCF, referred to as "S-CSCF"). 代理CSCF ( Proxy CSCF,筒称"P - CSCF")是用户设备(User Equipment,简称"UE")接入IMS系统的入口,实现了在SIP 协议中的代理(Proxy )和用户代理(UserAgent)功能;MGCF和IMS - MGW 是与CS域和PSTN互通的功能实体,分别负责控制信令和媒体流的互通; MRFC和MRFP是实现多方会议的功能实体,控制层面的MRFC通过H.248 控制MRFP; BGCF是IMS域与外部网络的分界点,它选择在哪里跟CS域或PSTN互联。 Proxy CSCF (Proxy CSCF, said cartridge "P - CSCF") is a user equipment (User Equipment, referred to as "UE") access to the inlet of the IMS system, realized in the SIP proxy (Proxy) and a user agent (UserAgent) function; MGCF and IMS - MGW is a functional entity CS domain and PSTN interworking, are responsible for controlling the exchange signaling and media streams; MRFC and MRFP are functional entities to achieve multi-party conference, the control plane MRFC MRFP through H.248 control ; BGCF is the demarcation point IMS domain and the external network, select it in the CS domain or where interconnection with the PSTN.

在IMS中,业务由应用服务器AS统一提供,会话控制由S-CSCF完成, 两者在网络结构上完全分离,业务由S-CSCF通过签约规则触发至AS处理, 多个AS间可以协同工作。 In IMS, a unified service provided by the application server AS, session control performed by S-CSCF, the two are completely separated on the network architecture, traffic triggered by S-CSCF to the AS through the subscription rule processing, among a plurality of AS may work together. IMS用户通过当前位置所在地的拜访域节点P-CSCF接入IMS,会话和业务控制总由其签约所在地的归属域节点完成, IMS的会话控制和业务控制功能与接入无关。 IMS user through a current location visited domain position of the node P-CSCF to access the IMS, session, and total service control node by the home domain completed subscription location, session control and service control function of the access independent IMS. IMS的用户签约数据集中在HSS中管理。 IMS user subscription data in the HSS centralized management. IMS通过媒体网关控制节点MGCF实现和固网电路域的互通呼叫:即IMS域用户和固网电路域用户之间,可以相互的呼叫对方。 The MGCF and IMS interworking call achieved by fixed circuit domain media gateway control node: i.e. the IMS domain between user domains and the fixed network subscriber circuit, can call each other mutually. 相对于其他业务,IMS业务具有许多优点,比如它支持WEB自助,用户可以非常直观的进行业务自助管理和业务定制,如定制智能路由、彩铃、 主叫彩像、任务和提醒、区别振铃、缩位号码、呼出限制、呼入限制等多种业务,大大简化了用户签约和登记业务的手续。 Compared to other business, IMS business has many advantages, such as its support for self-WEB, users can conduct business very intuitive self-management and service customization, such as customized intelligent routing, ring tones, caller-color images, tasks and reminders, distinctive ringing, abbreviated numbers, outgoing call restrictions, barring of incoming calls and other services, greatly simplifying the business user subscription and registration procedures. 另外,IMS业务支持通过某种控制代理终端(如WEB Client方式),在图形界面上点击控制业务流程, 用户可以非常直观的操作业务,如点击拨号、点击会议、点击保持、点击恢复、点击转移、点击排队、点击退出、点击接通等多种业务操作,大大简化了用户使用业务时的繁瑣操作步骤。 Addition, IMS provides service support terminal through some control agent (e.g., WEB Client mode), click on the graphical interface control business processes, user traffic can be very intuitive operation, such as a click dialing, conference click, click on hold, recovery click, click transfer click queue, click exit, click ON and other business operations, greatly simplifying the complicated operation procedure when the user using the service. 另外,由于IMS是3GPP标准为移动网定义的核心网,为移动用户提供的业务,如果在固定终端能力允许的情况下或在通过某种控制代理终端配合的情况下,为固网电路域用户服务,实现设备重用,节余运营商投资,而且可以带来固网用户新的业务增长点,其效益是不言自明的,因此基于IMS的网络融合方案是当前研究热点。 Further, since the IMS core network the 3GPP standard defined for the mobile network, to provide services for mobile users, if in case of a fixed terminal or capability allows some control in the case of the agent through the terminal fitting, for fixed CS user services, and equipment reuse, savings operators to invest, but also bring new business growth fixed-line users, the benefits are self-evident, therefore IMS-based network convergence solution is current research focus. 基于IMS的网络融合方案目的是使IMS成为基于SIP会话的通用平台,同时支持固定和移动的多种接入方式,实现固网和移动网的融合。 Fusion IMS based network program object is to be IMS SIP session based on a common platform, while supporting a variety of fixed and mobile access, to achieve convergence of fixed and mobile networks. 但目前由于技术限制,IMS只能支持固网电路域用户和IMS域用户之间的呼叫互通, 并不能通过IMS为固网电路域用户提供业务,固网电路域用户在互通呼叫时, 呼叫信令路由不经过IMS AS;而当IMS为其提供业务时,呼叫信令路由被S-CSCF触发至IMS AS,由AS完成业务控制。 But due to technical limitations, only support IMS interworking call between the fixed network CS user and an IMS domain user, and can not provide services through the IMS domain user circuit for the fixed network, the fixed network interworking CS user during a call, call signal IMS makes routing without the aS; when the IMS to provide services, call signaling route S-CSCF is triggered to the aS IMS, service control is completed by the aS. IMS对固网NGN的支持即要求IMS同时支持各种固定接入方式和移动接入方式是当前业界的技术难题。 IMS supports fixed network, i.e. in claim NGN IMS supports a variety of fixed access and mobile access to this technical problem is the industry. 虽然IMS的呼叫控制采用互联网工程任务组(Internet Engineering Task Force,简称"IETF")规定的S1P协议,但针对移动接入的特点进行了相应的增强和舍弃,主要体现在登记、鉴权和会话策略等方面,具体消息流程和IETF的规定有一些差别,因此电路交换域用户要接入IMS需要重新制定会话协议。 Although IMS call control the use of the Internet Engineering Task Force (Internet Engineering Task Force, referred to as the "IETF") provisions of S1P agreement, but the characteristics of mobile access were appropriate to enhance and give up, mainly in registration, authentication and session terms of strategies, processes and specific provisions of the IETF's news there are some differences, so the circuit switched domain user to access IMS needs to re-enact the session protocol. 目前为了提供给固网电路域用户业务服务,PSTN/ISDN网络通过数字程控交换机和智能网节点实现固网用户的业务接入。 In order to provide a fixed current CS domain user traffic service, PSTN / ISDN networks fixed user access via digital PBX services and intelligent network node. 该方案由于呼叫控制和业务控制功能在同一个网络节点中完成,灵活性差,不利于业务的快速部署和扩展。 Since the program call control and service control functions done in the same network node, inflexible and not conducive to the rapid deployment and expansion of the business. 一个功能的修改可能会引发另一个功能的变动,增加了潜在的风险;某些业务的部署和扩展甚至会引起整个网络节点的升级,成本较高,部署较慢。 Modify a function may lead to change another function, increasing the potential risks; deploy and expand business even cause some to upgrade the entire network nodes, high cost, slow deployment. 其次,由于数字程控交换机和智能网只能提供单纯的电路域业务,用户的人机交互方式单一,业务体验性较差,用户只能在固定终端上通过拨号按键方式使用业务、设置业务,用户需要记忆各种业务码甚至是业务流程,用户使用业务的积极性不高,不利于业务的推广。 Second, since the digital program-controlled switches and intelligent network can offer a simple circuit domain service, the user of a single human-computer interaction, the service experience is poor, the user can use the service by dialing a key way on the fixed terminal, provided services, the user need to remember a variety of business code or even business process, business users are not enthusiastic, is not conducive to the promotion of business. 另外,虽然现有的IMS提供了业务管理、会话控制及承载接入三者分离的机制,可以提供基于分组网络的丰富的多媒体业务,且IMS的网络结构也支持固定移动融合业务,但IMS标准只支持和固网电路域用户的互通呼叫, 并不支持为固网电路域用户提供业务应用。 Further, although the conventional IMS provides service management, session control mechanism for three separate bearer access and can provide rich multimedia services a packet-based network and the IMS network structure also supports fixed-mobile convergence service, but the IMS standards supports only users and fixed network domain interworking call circuit, does not provide support for the fixed-line business applications CS user. 所以当运营商同时拥有IMS网络和固定网络时,需要重复开发业务以给固网用户提供IMS业务。 So when operators have both IMS and fixed networks, the need to develop repeat business to provide IMS services to fixed-line users. 在实际应用中,上述方案存在以下问题:直接通过电路域的网络节点给固网用户提供业务的方案成本高、部署慢,且用户使用界面单一,不利于推广;而通过现有IMS网络给固网用户提供业务的方案则需要重复开发业务, In practical applications, the presence of the above-described embodiment the following problems: high fixed network users directly supplied to the circuit domain through the network node traffic program cost, slow deployment, and a single user interface, is not conducive to the promotion; and prior to the IMS network through the solid network users to provide business solutions you need to develop repeat business,

不能直接让固网用户接入IMS服务,运营成本高。 Not directly fixed network users accessing IMS services, high operating costs. 造成这种情况的主要原因在于,现有固网电路交换方式不够灵活,网络设施成本高昂;而IMS网络没有提供直接给固网用户接入的会话协议,固网用户无法直接使用IMS提供的服务。 The main reason for this situation is that the existing fixed-line circuit-switched inflexible, costly network facilities; and IMS network does not provide direct user access to fixed-line session protocol, the fixed-line users can not use the direct services provided by the IMS . 发明内容有鉴于此,本发明的主要目的在于提供一种通过分组域为电路域用户提供业务的方法,使得固网用户能够直接接入IMS,使用IMS服务,实现固网和移动网的在业务层面的融合和重用„为实现上述目的,本发明提供了一种通过分组域为电路域用户提供业务的方法,包含以下步骤,基于网际协议的多媒体子系统中的媒体网关控制功能判断信令路径经过该媒体网关控制功能的固网电路域用户是否签约了基于网际协议的多媒体子系统业务,如果是则则进行信令消息及消息内容参数的必要转换,向相应服务呼叫会话控制功能发送会话发起协议请求消息;所述服务呼叫会话控制功能响应来自媒体网关控制功能的会话发起协议请求消息,获取当前处理对象的业务签约信息后进行会话控制,并向业务相应的应用服务器发送会话发起协议请求消息;所述应用服 SUMMARY OF THE INVENTION Accordingly, the main object of the present invention is to provide a method for providing a service by a CS user packet domain, so that the user can directly access the IMS fixed network, using the IMS services, and fixed and mobile networks in the service level integration and reuse "to achieve the above object, the present invention provides a method of providing a service through a CS user packet domain, comprising the following steps, based on the control function determines the signaling path in internet protocol multimedia subsystem media gateway whether the CS user through the fixed network of the media gateway control function subscribes to an internet protocol multimedia subsystem service, and if necessary converting the signaling message and the message contents parameters, to initiate a corresponding service call session control function sends the session protocol request message; a serving call session control function in response to a session initiation protocol from the media gateway control function request message to obtain the service subscription information after the current target of processing session control, service request message to the corresponding application server transmits a session initiation protocol ; the application server 器响应来自所述服务呼叫会话控制功能的会话发起协议请求消息,获取当前处理对象的业务签约信息后对所述电路域用户进行业务控制。其中,在所述基于网际协议的多媒体子系统的归属用户服务器中存储与所述固网电路域用户有关的签约信息,供该基于网际协议的多媒体子系统中的其它设备查询和下载。 Session initiation protocol response from the serving call session control function request message, acquires the current processing target domain service service control circuit after the user subscription information.

PSTN局间信令有多种,在本发明的较佳实施例中,使用其中的一种ISDN 用户部分(ISDN User Part,简称"ISUP")信令中的起始地址消息(Initial Address Message,简称"IAM")来描述。 There are many inter-exchange signaling PSTN, in the preferred embodiment of the present invention, wherein using one of the ISDN User Part (ISDN User Part, referred to as "ISUP") initial address message (Initial Address Message signaling, referred to as "IAM") is described. 其中IAM消息中指示该呼叫为固网用户且签约IMS业务。 Wherein the IAM message indicating that the call is a fixed network subscription and the IMS service user. 在本发明的一个较佳实施例中,PSTN向MGCF发送IAM消息时,通过在IAM消息中的必选参数"被叫用户号码"增加某个特定前缀码来指示主叫用户签约了IMS业务,需要IMS为其提供业务控制。 In one preferred embodiment of the present invention, PSTN sends an IAM message to the MGCF, through the IAM mandatory parameter "called party number" add a specific prefix to indicate that the calling user subscribes to an IMS service, the need to provide IMS service control. 接着进入步骤212,当MGCF收到IAM消息后,对消息中的"被叫用户号码"进行号码分析,根据其特定的前缀码判断出主叫用户签约了IMS业务,同时删除该前缀码得到真实的被叫用户PSTN号码。 Proceeds to step 212, after the MGCF receives the IAM message, the message in the "called number" for number analysis, it is determined that the calling user subscribes to the service according to their particular IMS prefix code, and removes the prefix code obtained real PSTN number of the called party. 由于IMS网络中用户标识都是SIPURL格式,而PSTN中用户号码表示都是E.164格式,因此, MGCF需要首先向电子编码服务器(Electronic Numbering Server,简称"ENUM Server")请求将主叫用户号码从E.164格式转译成SIP URL格式。 Since the IMS network user identifier is SIPURL format, the PSTN subscriber number in E.164 format is represented, therefore, the MGCF needs to first server to the electronic coding (Electronic Numbering Server, referred to as "ENUM Server") requesting the caller number from E.164 format translated into SIP URL format. 这里ENUM Server需要存储管理固网电路域用户号码域SIP URL的相应转换关系。 Here ENUM Server relational storage management requires a corresponding conversion of fixed CS user number of SIP URL domain. 然后进入步骤213, ENUM Server通过配置查询将主叫用户号码从E.164 And then proceeds to step 213, ENUM Server query by configuring the calling party number from E.164

格式转译成SIPURL格式,并将转译结果返回给MGCF 。 Format translated into SIPURL format and translates the results back to the MGCF. 然后进入步骤214, MGCF将IAM消息转译成SIP请求(INVITE)消息,INVITE消息中的主叫地址采用转译后的SIP URL格式。 Then proceeds to step 214, MGCF converts the IAM message translated to SIP request (INVITE) message, the source address in the INVITE message using the SIP URL format after translation. 同时在INVITE 消息中指示主叫用户是固网电路域用户,签约了IMS业务的标志。 At the same time the caller indicated in the INVITE message is a fixed network CS domain user, the subscription service indication in the IMS. 在本发明一个实施例中,通过在INVITE消息中的"呼叫信息"(Call-Info )头域提供了主叫用户或被叫用户的附加信息中的参数"目的"(purpose)的扩展定义指示主叫用户是固网电路域用户并签约了IMS业务。 In one embodiment of the present invention, there is provided by the calling user or the called user, "call information" (Call-Info) header in the INVITE message with additional information about the parameter "object" (Purpose) extended definition indication is fixed calling user subscribes CS user and an IMS service. MGCF将INVITE消息发送给S-CSCF1。 The MGCF sends an INVITE message to the S-CSCF1. (这里用S-CSCFl代表处理主叫会话控制的S-CSCF,即主叫S-CSCF; S"CSCF2代表处理被叫会话控制的S-CSCF,即被叫S-CSCF)接着进入步骤215,在S-CSCF1收到INVITE消息后,处理主叫用户的会话控制。根据消息中Call-Info头域的purpose参数值判断出主叫用户是固网电路域用户并签约了IMS业务。S-CSCF 1查询该用户的签约数据若不存在, 则向HSS请求下载该用户的签约数据。S-CSCFl根据下载得到的用户的业务签约规则触发一个IMS AS1 (这里用AS1表示是对主叫进行业务控制,即主叫AS; AS2表示是对被叫进行业务控制,即被叫AS) , S-CSCFl向该ASl 发送INVITE消息,消息中仍然要指示主叫用户是固网电路域用户并签约了IMS业务。接着进入步骤216,当IMS AS1收到【NVITE消息,根据消息中Call-Info 头域的purpose参数直判断出主叫用户是固网电^各J:或用户并签约了IMS业务。 AS1查询该用户的签约数据若不存在, (Where treated with S-CSCFl S-CSCF on behalf of the calling session control, i.e. the calling party S-CSCF; S "Representative CSCF2 process called S-CSCF session control, i.e. the called S-CSCF) then proceeds to step 215, after the S-CSCF1 receives the INVITE message, the calling user session control process. determines that the calling user according to the purpose parameter value in the message Call-Info header field is fixed CS user and an IMS subscription service .S-CSCF 1 subscription data of the user query if there is a request to the HSS to download the user subscription data .S-CSCFl AS1 according to the IMS triggers a service subscription rules downloaded user (here denoted by AS1 is calling for service control , i.e. the calling party AS; AS2 expressed is called service control, i.e., the called party AS), S-CSCFl to ASl sends an INVITE message, the message indicates to the calling subscriber is still fixed CS user and an IMS subscription the traffic then proceeds to step 216, when the IMS receives ASl [NVITE message, according to the purpose parameter message Call-Info header field is determined that the caller is directly fixed each electrically ^ J: or a user subscribes to an IMS service and ASl. queries the user's subscription data if not, 向HSS请求下载该用户的签约数据。 AS1根据用户签约数据下载结果,进行相应的业务控制,处理完毕,向S-CSCFl发送INVITE消息。最后在步骤217中,S-CSCFl收到INVITE消息,继续对主叫用户进行业务触发或对被叫用户进行路由寻址。如果继续有新的业务AS被触发,则S-CSCFl向新AS发送INVITE消息,该消息中仍然要指示主叫用户是固网 Requesting the HSS to download user subscription data. AS1 according to the user subscription data download result, the corresponding service control processing is completed, transmits an INVITE message to the S-CSCFl. Finally, in step 217, S-CSCFl receiving the INVITE message, to continue the calling user to the called user or service triggering routing address. If you continue new service AS is triggered, S-CSCFl transmits a new INVITE message to the AS, the message indicates to the calling subscriber is still fixed

电路城用户并签约了IMS业务,流程重新进入步骤216;否则,S-CSCF1完成对被叫用户的路由寻址功能。 Circuit City and signed the IMS service user, process re-enters step 216; otherwise, S-CSCF1 performs a routing function for addressing the called subscriber. 图2(b)示出了根据本发明的一个实施例的固网电路域用户被叫且呼出路径进入IMS域时IMS业务处理流程。 FIG 2 (b) shows a process when the IMS service domain user according to a fixed circuit embodiment of the present invention is called and exhalation path into the IMS domain. 当呼入一个固网电路域用户,此次呼入需要IMS为该被叫用户提供某种业务应用控制,而该呼叫的前半段,即呼出信令路径已经进入了IMS,主叫用户的业务处理完毕,IMS对固网电路域被叫用户进行路由寻址。 When an incoming call a fixed network subscriber circuit domain, the incoming call requires a certain service provided by the IMS application control for the called user, and the first half of the call, i.e., outgoing signaling path has entered the IMS, service calling subscriber processed, IMS for fixed circuit addressing domain called user. 首先在步骤221中,S-CSCF1对固网电路域被叫用户进行路由寻址,被叫地址为E.164格式,则向ENUM Server请求将被叫用户号码从E.164格式转译成SIP URL格式。 First, in step 221, S-CSCF1 fixed network CS domain called user address, called address format to E.164, ENUM Server requests to the called subscriber number is translated into the E.164 format from the SIP URL format. 接着进入步骤222中,ENUM Server通过配置查询将4皮叫用户号码从E.164格式转译成SIP URL格式,并将转译结果返回给S-CSCF1 。 Then proceeds to step 222, ENUM Server query by arranging the sheath 4 from the calling subscriber number in E.164 format translated to SIP URL format, and returns the result to the translation S-CSCF1. 接着进入步骤223中,S-CSCF1得到SIPURL格式的被叫用户号码,向被叫归属域的S-CSCF2发送INVITE消息,消息中的被叫地址采用转译后的SIP URL格式。 Proceeds to step 223, S-CSCF1 obtained SIPURL format called party number, the called party sends an INVITE message to the home domain S-CSCF2, called address in the message format using the SIP URL translations. S-CSCF1对S-CSCF2的路由寻址方法完全和3GPP IMS标准定义的相同,本发明不再描述。 S-CSCF1 for the S-CSCF2 exactly the same routing and addressing methods 3GPP IMS standard defined by the present invention is not described. 接着进入步骤224中,S-CSCF2收到INVITE消息,处理被叫用户的会话控制。 Then proceeds to step 224, S-CSCF2 receiving the INVITE message, the called user session control process. 查询被叫用户的签约数据若不存在,则向HSS请求下载,并根据下载得到的用户的业务签约规则触发一个IMS AS2,由该AS2为被叫用户提供相关的业务应用控制。 Query the called user subscription data if there is a request to the HSS to download and triggers a service subscription rules according to IMS AS2 downloaded to the user, the application service provide control of the called user AS2. S-CSCF2向该AS2发送INVITE消息。 S-CSCF2 sends an INVITE message to AS2. 接着进入步骤225中,IMS AS2收到INVITE消息,查询被叫用户的签约数据若不存在,则向HSS请求下载,并根据用户签约数据下载结果,进行相应的应用业务控制,处理完毕,向S-CSCF2发送INVITE消息。 Then proceeds to step 225, IMS AS2 receives the INVITE message, the called user's subscription data query if there is a request to the HSS to download, and the download result data according to the user subscription, the service control corresponding application, the process is completed, the S -CSCF2 sends an INVITE message. 接着进入步骤226中,S-CSCF2收到来自AS的INVITE消息,继续对 Then proceeds to step 226, S-CSCF2 receiving the INVITE message from the AS, continues to
