处理方法。 Approach.

背景技术 Background technique

智能网是在传统电路交换网基础上,为快速提供新业务而设置的附加业务 Intelligent Network in the traditional circuit-switched network base to quickly provide new services and set up additional business

网络结构。 Network structure. 一般典型的智能网体系结构包括业务控制点(SCP)和业务交换点(SSP),两者之间通过智能网应用规程进行交换。 Usually typical intelligent network architecture including a service control point (SCP) and the service switching point (SSP), by exchange between the intelligent network application protocol. 目前智能网的发展与应用越来越广泛,能为用户提供诸如800号免费电话、300号记帐卡> 广告业务、预付费业务等众多新型业务。 Currently the development and application of intelligent network is widely applied, it can provide services such as toll-free 800 number for the user, debit card number 300> advertising business, prepaid services and many new services.

语音IP (VoIP)作为一种基于分组交换网络的新兴语音通信技术也已显示出越来越重要的地位。 Voice IP (VoIP) as an emerging packet-based voice switching network communication technology has also been shown increasingly important role. 但是目前的VoIP网络还仅限于提供基本的语音传输服务.,而且与传统电路交换技术相比,VoIP技术还处于发展阶段。 However, the current VoIP network also limited to providing basic voice transmission services, and compared to traditional circuit-switched technology, VoIP technology is still in development stage. 目前VoIP网络存在多种多样的形式,如:基于H.323信令的VoIP网络、基于SIP信令的VoIP网络等等,不同VoIP网络之间还难以做到相互融合以及业务提供方式上的统一,从用户角度还存在很多使用上的不方便之处。 VoIP network currently exist a variety of forms, such as: Signaling VoIP network based on H.323, SIP-based VoIP network signaling and so on, but also difficult to achieve mutual integration between different VoIP networks and services to provide a unified way on from a user's perspective there are many inconveniences in use.

随着语音通信市场需求的快速发展.为IP用户提供智能业务已成为VoIP 技术发展的迫切需要。 With the rapid development of voice communications market needs. IP users to provide intelligent service has become an urgent need for technological development of VoIP. 由于现有智能网的大规模应用以及技术上的成熟性,将传统智能网业务应用于IP网络,实现智能网技术和VoIP技术的集成,已成为当前语音IP技术发展的方向。 Due to large-scale applications as well as the maturity of the existing intelligent network technology, the traditional intelligent network service applied to an IP network, intelligent network technology to achieve integration and VoIP technology, voice over IP has become the current direction of technology development. 另一方面,随着VoIP网络的进一步发展,采用以软交换(Softswitch)为核心的全新VoIP技术成为构建下一代网络的主流方向。 On the other hand, with the further development of the VoIP network, VoIP technology with a new soft switch (Softswitch) as the core of the building to become the mainstream of the next generation network. 从智能网与VoIP网络集成的角度来说,软交换可以提供一种从VoIP网络接入智能网的解决方案。 From the intelligent network and VoIP network integration point of view, the softswitch can provide an intelligent network access solutions from the VoIP network.

从业务提供的角度来说,智能网系统包含两个基本的功能实体:业务控制点和业务交换点,业务控制点是业务逻辑运行的平台,业务交换点则是提供呼叫控制以及业务接入的平台。 From the perspective of the service provider, the intelligent network system comprises two basic functional entities: a service control point and a service switching point, a service control point service logic operation platform, the service switching point is to provide call control, and service access platform. 在传统智能网中,业务控制点和业务交换点之间的交互由业务交换点中的一个通用的模型控制,该模型称为基本呼叫状态模型 In a traditional intelligent network, the interaction between the service control point and a service switching point a general model of a control by a service switching point, the model is called Basic Call State Model

(BCSM )。 (BCSM). BCSM主要用于规范一个呼叫发起方和一个呼叫接收方之间建立和维持一条通信路径所需要的基本呼叫处理状态。 BCSM is designed to regulate a call originator and a call establishing and maintaining a basic call processing state of the communication path between the desired recipient. 如图la所示,BCSM通常分为两部分:发端基本呼叫状态模型(O-BCSM)和收端基本呼叫状态模型 As shown in FIG. La, BCSM usually divided into two parts: the originating basic call state model (O-BCSM) and terminating basic call state model

(T-BCSM ),分别处理与呼叫发起方和呼叫接收方相关的操作。 (T-BCSM), each processing operation associated with the call originator and the call recipient.

在智能网体系结构中,BCSM是接入智能网业务的关键,BCSM包括若干代表呼叫和连接处理过程的特殊状态。 In the intelligent network architecture, BCSM is the key to access the intelligent network service, BCSM and comprising a plurality of agent call connection processing procedure of the special state. 在呼叫处理过程中,BCSM通过执行从-一个状态到另一个状态的基本迁移,检测能导致智能网业务逻辑实例调用的基本呼叫和连接控制事件,判断是否允许与智能网业务逻辑交互,如果对应的触发点被配置,并且满足预设的触发条件,呼叫处理过程将会被挂起,并触发相应的智能业务逻辑,从而实现接入智能业务的目的。 In the call processing, the BCSM by doing a - a basic migration state to another state, the detection can result in the basic call intelligent network service logic instance call connection control events and determines whether to allow interaction with the intelligent network service logic, if the corresponding the trigger point is configured, and satisfies preset trigger conditions, call processing will be suspended, and triggers the corresponding intelligent service logic, in order to achieve the purpose of access to intelligent service. O-BCSM和T-BCSM中对PIC呼叫状态的定义分别如图lb和图lc所示。 O-BCSM and T-BCSM defined in the PIC call status are shown in Figure lb and lc shown in FIG.

因此,软交换要提供从VoIP网^入智能网业务的解决方案,实现智能网技术和VoIP技术的集成,就必须提供智能网所需要的业务交换功能和呼叫控制功能,其中最关键的就是要解决VoIP域目前并存的多种形式各异的呼叫处理流程与智能网域要求的规范化呼叫处理流程相互融合的问题,也就是,要对VoIP 网络中基于特点各不相同的多种异质呼叫信令,如H.323、 SIP、 MGCP、 SIGTRAN等,实现遵循智能网规范的统一的呼叫控制流程和业务触发模式。 Therefore, the softswitch to provide solutions from the VoIP network ^ into intelligent network services, to achieve integrated intelligent network technology and VoIP technology, it is necessary to provide the service switching function and call control function of the intelligent network needs, the most critical is to VoIP domain is currently solve the problem of coexistence of different forms and intelligent call processing flow domain requires the standardization of call processing flow of mutual integration, that is, to be on the VoIP network based on the characteristics of each different call letters more foreign order, such as H.323, SIP, MGCP, SIGTRAN, etc., to achieve a unified call control processes and business models to follow triggering the intelligent network specifications. 此外,考虑到未来VoIP业务的多样性以及用户终端的多样性,在按照智能网模式处理VoIP呼叫的过程中,还需要提供信令中介功能,也就是,软交换还必须解决在同一个呼叫处理流程实现不同呼叫控制信令之间的转换或互操作问题,比 In addition, taking into account the diversity and future diversity of user terminals VoIP service, VoIP calls during the processing in accordance with the intelligent network model, also need to provide signaling intermediary function, that is, softswitch must also be addressed in the same call handling processes conversion between different call control signaling or interoperability issues, than

如:H.323和SIP间的互操作,H.323和SIGTRAN间的互操作,MGCP和SIP间的互操作等。 Such as: interoperability between H.323 and SIP, H.323 and interoperability between SIGTRAN interoperability between, MGCP and SIP and the like. 发明内容 SUMMARY

具体实施方式 Detailed ways

从业务提供的角度来说,智能网系统业务交换点最普通的形式大体包括两种基本功能部分:呼叫控制单元和业务交换单元。 From the perspective of the service provider, the most common form of intelligent network service switching point system generally comprises two basic functional parts: the call control unit and switching unit. 其中,呼叫控制单元处理与呼叫处理相关的功能;业务交换单元处理所有与业务接入相关的功能。 Wherein the call processing functions of the control unit associated with the call processing; service switching unit handles all functions related to the service access. 通常情况下,呼叫控制单元和业务交换单元以有限状态机(FSM)的形式实现,进而达到追踪业务控制流程以及呼叫处理过程的目的。 Typically, the call control unit and switching unit is implemented as a finite state machine (FSM), and thus the purpose of tracking and traffic control flow of a call process.

为实现智能网技术与VoIP技术的融合,本发明提出了基于叠加方式的业务域间集成架构,如图2所示。 To achieve integration of intelligent network technology and the VoIP technology, the present invention provides inter-domain based service integration architecture superimposed manner, as shown in FIG. 图2中,业务域间集成架构同时支持智能网域业务交换单元、智能网域呼叫控制单元和VoIP域呼叫控制单元。 In FIG. 2, inter-domain traffic domain integration architecture supports intelligent service switching unit, the intelligent call control unit, and the domain-domain VoIP call control unit. 集成呼叫系统包括智能网域呼叫控制单元和VoIP域呼叫控制单元,,其中,智能网域呼叫控制单元和VoIP域呼叫控制单元分别具有各自的技术特征,VoIP域呼叫控制单元与智能网域呼叫控制单元根据呼叫处理特点的不同分别定义了面向各自域特点的不同形式的有限状态机(FSM)。 The system includes a intelligent integrated call the domain-domain call control unit and VoIP call control unit ,, wherein the intelligent call control unit and VoIP domains domain call control unit have their respective technical features, VoIP domain call control means and intelligent call control domain the call processing unit according to the different characteristics are defined for each of the different forms of domain characteristics of a finite state machine (FSM). 本发明中,智能网域呼叫控制单元的形式与图la所示结构相同,分为发端呼叫控制单元和收端呼叫控制单元,其包含的呼叫状态定义也与图lb和图lc所示组成结构相同。 In the present invention, in the form of domains with intelligent call control unit in FIG. La is shown the same configuration, the control unit into the call originating and terminating call control unit, comprising a call state is also defined in Fig. Lb and lc composition structure shown in FIG. the same. VoIP域的呼叫控制单元则根据所使用信令的分为多种类型,并且其包含的呼叫状态定义也各不相同,比如:H.323呼叫控制单元、SIP呼叫控制单元、MGCP呼叫控制单元。 VoIP call control unit in accordance with the field is divided into a plurality of types of signaling used and which contains the call state definitions vary, for example: H.323 call control unit, the SIP call control unit, MGCP call control unit.

本发明基于图2所示的集成呼叫处理架构,在保持智能网域呼叫处理模式和VoIP域各自呼叫处理模式的技术特征不发生改变的情况下,实现VoIP域呼叫控制模式和智能网域呼叫控制模式的集成,由智能网域呼叫控制单元和VoIP 域呼叫控制单元共同完成对呼叫处理过程的控制。 The present invention is based on the integrated call processing architecture shown in Figure 2, while keeping the intelligent call processing mode and domain-domain VoIP call processing each technical feature does not change, the VoIP call control domain model and intelligent call control domain integration mode, by the intelligent call control unit, and the domain-domain VoIP call control unit performs control of call handling procedures common. 概括地说,本发明的基本原理是:首先制定VoIP域呼叫控制状态与智能网域呼叫控制状态之间的等价映射关系,然后在呼叫处理过程中依据这种等价映射关系控制两者呼叫状态的动态迁移过程,实现两者在呼叫处理步骤上的语义一致性。 In summary, the basic principles of the present invention are: First, the development of mapping between the equivalent domains VoIP call control and intelligent state domain call control state, both the call and the control of such equivalence mapping relationship based call processing dynamic migration state, both semantic consistency achieved on the call processing procedure.

VoIP域呼叫控制单元与智能网域呼叫控制单元之间的状态等价映射可采用四种方式: 一对一、 一对多、多对一和多对多,如图3a所示。 VoIP domain call state between the control unit and the intelligent call control unit equivalent domain can be mapped in four ways: one, one to many, and many-to-many, shown in Figure 3a. 其中,多对多映射的情况可能会带来二义性问题,使FSM关联状态之间的迁移出现混乱。 Among them, the case-many mapping may lead to ambiguous questions, so that migration between FSM state associated with confusion. 比如:图3a中智能网域呼叫控制单元(FSM A)中的状态S被分别映射到VoIP 域呼叫控制单元(FSMB )的状态J和状态K,但FSMB中的状态J与FSMA 中的状态R也存在一个映射。 For example: the state of FIG. 3a intelligence domain call control unit (FSM A) in the S domain are mapped to a VoIP call control unit (FSMB) J and the state of state K, J and FSMA FSMB state but in a state R there is also a map. 这种情况下,应采用如下补偿方式予以避免:保持智能网域FSM A呼叫状态不变,将VoIP域FSM B中的状态J和状态K合并成--个状态来处理,并同时映射到智能网域FSMA中的状态R和状态S,如图3b所示。 In this case, the compensation should be avoided as follows: an intelligent network domain FSM A holding call state change, the state of the J and the state of the FSM B VoIP domains combined into K - states to process, simultaneously and mapped to the smart R state and the state domain FSMA S, as shown in FIG. 3b.

在本发明的叠加呼叫处理过程中,VoIP域呼叫控制单元与智能网域呼叫控制单元将根据状态之间的等价映射关系完成对呼叫的关联处理,即:在呼叫处理过程中,任何一方呼叫控制单元的状态迁移行为都将启动对方等价状态的同步迁移,这一过程通过在VoIP域呼叫控制单元与智能网域呼叫控制单元之间传递状态迁移控制令牌实现。 Superimposing call processing of the present invention, VoIP domain call control means and intelligent domain call control unit associated with the completion of the processing of the call according to the mapping relationship between the equivalent state, namely: in the call processing, call either state transition behavior of the control unit will start to migrate other equivalent synchronized state, a process by the control unit between a VoIP call and intelligent field domain call control unit controls the transmission state migration token implementation. 当某一个呼叫控制单元启动一次状态(或状态序列) 迁移后,将同步向对应呼叫控制单元呼叫发送状态迁移控制令牌,只有当收到该令牌的呼叫控制单元也完成与之等价的状态迁移后,才能再起动下一次的呼叫状态迁移过程。 When one of the control unit to initiate a call state (or state series) migration, synchronization state transition control unit transmits the call to a corresponding token call control, only when receiving the token call control unit also completed equivalent thereto after the state transition in order to re-start the next call state migration process. 所述状态迁移控制令牌携带有特定的状态映射指示信息,收到控制令牌的呼叫控制单元将根据令牌中携带的信息决定呼叫状态的迁移方式。 The state transition control token carries information indicative of a specific state mapping, the token is received the call control unit determines the call state migration patterns based on the information carried in the token. 在上述叠加呼叫处理方法中,衣发明中根据智能网域呼叫控制单元的需要, 设定了八种主要的控制令牌,其名称与含义如表一所示。 In the call processing method of superimposing, it requires a smart garment according to the invention the domain call control unit is set eight primary control token, a name the same meaning as shown in Table.
