一种支持WEB业务和多浏览器的SIP软终端及其工作方法A kind of SIP soft terminal supporting WEB service and multi-browser and its working method

技术领域technical field

本发明涉及一种可跨浏览器和支持WEB业务的SIP软终端技术，确切地说，涉及一种支持WEB业务和多浏览器的SIP软终端及其工作方法，属于通信技术和互联网的技术领域。The present invention relates to a SIP soft terminal technology that can cross browsers and support WEB services, to be precise, relates to a SIP soft terminal that supports WEB services and multiple browsers and its working method, and belongs to the technical field of communication technology and the Internet .

背景技术Background technique

网络通信技术的飞速发展，为IP网实现多媒体实时传输提供了基础。目前，SIP软终端技术已经有了飞速发展，逐渐融合了传统电话终端的业务。SIP软终端是在因特网上通过SIP协议实现实时语音通话的一种VoIP网络终端，其中的软件大多是PC或智能手机上的应用程序，其基本原理是采用语音压缩编码算法对语音数据进行压缩编码处理，采用现有的TCP/IP协议将其语音数据包发送到接收端后，再对这些语音数据包进行解码解压处理，恢复为原来的语音信号，从而实现利用IP网络传送语音的目的。在语音的传输过程中，采用SIP协议实现信令交互，达到在通话过程中进行会话控制的目的。The rapid development of network communication technology has provided a foundation for IP network to realize multimedia real-time transmission. At present, the SIP soft terminal technology has developed rapidly, gradually integrating the services of traditional telephone terminals. The SIP soft terminal is a VoIP network terminal that realizes real-time voice calls through the SIP protocol on the Internet. Most of the software is an application program on a PC or a smart phone. The basic principle is to use a voice compression coding algorithm to compress and code voice data. Processing, use the existing TCP/IP protocol to send the voice data packets to the receiving end, and then decode and decompress these voice data packets to restore the original voice signal, so as to realize the purpose of using IP network to transmit voice. In the voice transmission process, the SIP protocol is used to realize signaling interaction, so as to achieve the purpose of session control during the call.

IP网络的不断发展与网络带宽的不断提高，带来了云计算的兴起，目前，传统WEB业务已经不能满足人们日益增长的通信需求，融合话音、视频与数据通信的多媒体信息的WEB业务应运而生。嵌入WEB业务的SIP软终端因其使用简单，无需用户手动安装相关软件而颇受亲睐，在用户使用系统默认浏览器的安全模式下，客户端通过加载默认浏览器中控件的方式，在用户打开企业网页时，自动下载到用户的PC终端。SIP软终端能够在WEB页面中提供多媒体业务的原理是定义了一套可供WEB编程调用的基于JavaScript的、能够实现双向调用的软终端扩展接口。SIP软终端的核心逻辑的功能模块在收到网络通信事件后，通过这些接口调用WEB扩展业务中的JavaScript脚本；在WEB扩展业务中，JavaScript脚本又调用这些扩展接口，扩展接口最终调用SIP软终端核心逻辑的功能模块。The continuous development of IP networks and the continuous improvement of network bandwidth have brought about the rise of cloud computing. At present, traditional WEB services can no longer meet people's growing communication needs, and WEB services that integrate multimedia information of voice, video and data communications have emerged as the times require. born. SIP soft terminals embedded in WEB services are popular because they are easy to use and do not require users to manually install related software. When the enterprise web page is opened, it will be automatically downloaded to the user's PC terminal. The principle that SIP soft terminals can provide multimedia services in WEB pages is to define a set of JavaScript-based soft terminal extension interfaces that can be invoked by WEB programming and can realize two-way calls. After receiving the network communication event, the functional modules of the core logic of the SIP soft terminal call JavaScript scripts in the WEB extension service through these interfaces; in the WEB extension service, the JavaScript script calls these extension interfaces, and the extension interface finally calls the SIP soft terminal Functional modules of the core logic.

支持WEB业务和多浏览器的SIP软终端是基于IP网络，使用传统的SIP软终端的核心逻辑的功能模块，配合多种浏览器的适配接口，使得WEB上的多媒体业务能够在诸多浏览器上得以使用，从而为WEB上嵌入多媒体业务提供了条件，加速了WEB多媒体业务的发展和推广。支持WEB业务和多浏览器的SIP软终端的关键是使用SIP软终端技术能够利用Internet和全球IP互连的环境，提供比传统电话业务更廉价、更便利的话音和多媒体业务。除此以外，SIP软终端可在浏览器中使用，直接进入WEB页面下载后即可使用，不需另行安装；也可以嵌入如企业售后，餐饮咨询等网站。另外，其也有支持多浏览器的特性，根据用户使用的浏览器，动态透明地使用不同的技术策略，使得其适用范围得到明显拓宽，有利于推广和使用。The SIP soft terminal supporting WEB business and multi-browser is based on the IP network, using the core logic function module of the traditional SIP soft terminal, and cooperates with the adaptation interface of various browsers, so that the multimedia service on the WEB can be displayed in many browsers. It can be used on the Internet, thereby providing conditions for embedding multimedia services on the WEB, and accelerating the development and promotion of WEB multimedia services. The key to SIP soft terminals supporting WEB services and multiple browsers is to use SIP soft terminal technology to take advantage of the Internet and the global IP interconnection environment to provide voice and multimedia services that are cheaper and more convenient than traditional telephone services. In addition, the SIP soft terminal can be used in the browser, and can be used directly after downloading from the WEB page without additional installation; it can also be embedded in websites such as enterprise after-sales service and catering consultation. In addition, it also has the feature of supporting multiple browsers. According to the browsers used by users, it can dynamically and transparently use different technical strategies, so that its scope of application is significantly broadened, which is conducive to promotion and use.

现在研制成功的软终端大多是基于桌面开发和封装各种信令控制与媒体交互功能的客户端。其中信令控制使用H.323或SIP协议，媒体传输使用实时传输RTP协议。如果需要使用该类软终端，用户必须在PC机上手动安装相应的软终端客户端。Most of the successfully developed soft terminals are clients that develop and encapsulate various signaling control and media interaction functions based on the desktop. The signaling control uses the H.323 or SIP protocol, and the media transmission uses the real-time transmission RTP protocol. If you need to use this type of soft terminal, the user must manually install the corresponding soft terminal client on the PC.

文献《一种基于SIP的在线呼叫管理中心客户端的设计》(《黑龙江科技信息》2009(11)：66)提出一种基于ActiveX、能够嵌入IE浏览器的软终端的设计思路。但是，该文献没有对这个思路提供具体可行的设计流程和实现方法，其客户端也不支持视频通话。并且，基于ActiveX控件方式的解决方案的可行性前提是用户需要安装IE浏览器，因为ActiveX是基于微软COM组件，故只支持微软的IE浏览器，该思路的应用范围受到限制。The document "A Design of a SIP-Based Online Call Management Center Client" ("Heilongjiang Science and Technology Information" 2009 (11): 66) proposes a design idea for a soft terminal based on ActiveX that can be embedded in an IE browser. However, this document does not provide a specific and feasible design process and implementation method for this idea, and its client does not support video calls. Moreover, the feasibility premise of the solution based on the ActiveX control method is that the user needs to install the IE browser, because ActiveX is based on the Microsoft COM component, so it only supports the Microsoft IE browser, and the application range of this idea is limited.

上述文献的技术方案缺点是：一方面，基于桌面的软终端需要每个终端必须安装客户端软件方可使用，缺乏便捷性和灵活性。另一方面，上述文献提出的将软终端嵌入浏览器的思路，虽然从理论上可以解决问题，但是，没有提出具体可行的实现方法，也没有考虑到为多种浏览器提供支持。随着FireFox等非IE浏览器的日趋流行，仅仅基于ActiveX的软终端肯定无法满足更多用户的需求。另外，虽然如FireFox这样的浏览器已经提供了支持IE的扩展组件，使得仅支持IE的应用程序可以转移到IE中运行，但其仍需用户单独下载安装该组件，且也脱离了跨浏览器应用的理念。The disadvantages of the technical solutions of the above documents are: on the one hand, desktop-based soft terminals require that each terminal must be installed with client software before it can be used, which lacks convenience and flexibility. On the other hand, although the idea of embedding the soft terminal into the browser proposed by the above-mentioned documents can solve the problem theoretically, it does not propose a specific and feasible implementation method, nor does it consider providing support for multiple browsers. With the increasing popularity of non-IE browsers such as FireFox, only ActiveX-based soft terminals will definitely not be able to meet the needs of more users. In addition, although browsers such as FireFox have provided extension components that support IE, so that applications that only support IE can be transferred to run in IE, it still requires users to download and install the component separately, and it also breaks away from cross-browser support. Applied ideas.

因此，尽快研制一种能够支持音视频通话和各种WEB多媒体业务，且同时支持至少两种主流浏览器的软终端就成为业内科技人员关注的焦点。Therefore, developing a soft terminal capable of supporting audio and video calls and various WEB multimedia services as soon as possible, and supporting at least two mainstream browsers at the same time has become the focus of attention of scientific and technological personnel in the industry.

具体实施方式Detailed ways

为使本发明的目的、技术方案和优点更加清楚，下面结合附图和实施例对本发明作进一步的详细描述。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

本发明支持WEB业务和多浏览器的SIP软终端是对现有的桌面软终端配设能够支持WEB业务和多浏览器的各种接口，并以网页浏览器作为运行载体的多媒体终端。参见图1，介绍本发明SIP软终端中的两个关键部件：JavaScript接口和软终端装配模块，首先介绍第一个部件JavaScript接口：The SIP soft terminal supporting WEB service and multi-browser provided by the present invention is a multimedia terminal equipped with various interfaces capable of supporting WEB service and multi-browser on the existing desktop soft terminal, and using a web browser as a running carrier. Referring to Fig. 1, two key components in the SIP soft terminal of the present invention are introduced: the JavaScript interface and the soft terminal assembly module, first introducing the JavaScript interface of the first component:

JavaScript接口，设有两个子模块：软终端创建器和软终端扩展接口，分别负责完成两方面功能：第一，创建软终端装配模块，以达到将软终端基本功能嵌入浏览器的目的，该部分功能由软终端创建器完成；第二，在软终端基本功能嵌入到浏览器的基础上，为程序员提供开发各种WEB扩展业务的平台，这部分功能由软终端扩展接口承担。下面分别对其两个子模块作进一步介绍：The JavaScript interface has two sub-modules: the soft terminal creator and the soft terminal extension interface, which are responsible for two functions: first, create the soft terminal assembly module to achieve the purpose of embedding the basic functions of the soft terminal into the browser. The function is completed by the soft terminal creator; secondly, on the basis of embedding the basic functions of the soft terminal into the browser, it provides a platform for programmers to develop various WEB extension services, and this part of the function is undertaken by the soft terminal extension interface. The following are further introductions to its two sub-modules:

软终端创建器，因为将该SIP软终端嵌入到每种浏览器需要提供相应的浏览器适配接口来调用软终端功能模块，因此软终端创建器可以根据用户所使用的浏览器类型来创建基于相应浏览器适配接口的软终端装配模块。一旦软终端装配模块创建成功后，用户就能直接通过浏览器使用该SIP软终端的基本功能。Soft terminal creator, because embedding the SIP soft terminal into each browser needs to provide a corresponding browser adaptation interface to call the soft terminal function module, so the soft terminal creator can create a The soft terminal assembly module of the corresponding browser adaptation interface. Once the soft terminal assembly module is successfully created, the user can directly use the basic functions of the SIP soft terminal through the browser.

软终端扩展接口，它是一个接口群，是一组专供程序员进行WEB扩展业务开发的、支持双向调用的预留接口。该接口的工作方法是：先由软终端功能模块检测到网络中的通信事件，包括来电、挂机、忙碌或其它事件，当这些事件发生时，软终端功能模块通过软终端扩展接口调用WEB扩展业务中的JavaScript 脚本；接着，WEB扩展业务中的JavaScript脚本调用软终端扩展接口，该扩展接口再根据用户使用的浏览器类型选择相应的浏览器适配接口，并由相应的浏览器适配接口最终调用软终端功能模块中相应的功能接口；这样程序员就利用这些接口在软终端的基本功能模块上，开发出各种丰富的个性业务。例如，主叫端向被叫端发起呼叫，而被叫端长时间没有应答，这在现有的基本通话业务中的处理方式是：直接给主叫端回送超时信息，并告知主叫端，被叫端暂时无人应答，建议稍后再拨，同时终止呼叫过程。而本发明SIP软终端则在软终端扩展接口中设置一个发起呼叫接口，当软终端功能模块检测到超时事件时，可以利用该接口去调用软终端功能模块中的呼叫功能，这样，业务开发人员就可以利用该接口直接在JavaScript接口上实现自动重播业务，而无需知道底层软终端功能模块的工作机制。Soft terminal extension interface, which is an interface group, is a group of reserved interfaces that are specially designed for programmers to develop WEB extension services and support two-way calling. The working method of this interface is: first, the soft terminal function module detects communication events in the network, including incoming calls, hang-up, busy or other events, when these events occur, the soft terminal function module calls the WEB extension service through the soft terminal extension interface The JavaScript script in the WEB extension service; then, the JavaScript script in the WEB extension service calls the soft terminal extension interface, and the extension interface selects the corresponding browser adaptation interface according to the browser type used by the user, and the corresponding browser adaptation interface finally Call the corresponding function interfaces in the function modules of the soft terminal; in this way, programmers use these interfaces to develop various rich personalized services on the basic function modules of the soft terminal. For example, the calling terminal initiates a call to the called terminal, but the called terminal does not answer for a long time. This is handled in the existing basic call service: directly send back timeout information to the calling terminal, and inform the calling terminal, There is no answer from the called end at the moment, it is suggested to dial again later, and terminate the call process at the same time. However, the SIP soft terminal of the present invention sets a call initiation interface in the soft terminal extension interface. When the soft terminal function module detects an overtime event, the interface can be used to call the call function in the soft terminal function module. In this way, the business developer This interface can be used to directly realize the automatic replay service on the JavaScript interface without knowing the working mechanism of the underlying soft terminal functional modules.

本发明SIP软终端扩展接口有以下两类接口：The SIP soft terminal expansion interface of the present invention has the following two types of interfaces:

第一类，用于完成各种与呼叫和会话的相关功能的控制类接口，有六个：The first category is used to complete various functions related to calls and sessions. There are six control interfaces:

获取呼叫错误信息接口，调用软终端功能模块中的获取呼叫错误信息接口，获取通话双方过程中产生的错误代码和错误信息。Get the call error information interface, call the call error information interface in the soft terminal function module, and get the error code and error information generated by both parties during the call.

第二类是配置类接口，用于完成各种注册与帐号信息与媒体信息配置功能；配置类接口包括下述三个：The second type is the configuration interface, which is used to complete various registration and account information and media information configuration functions; the configuration interface includes the following three:

帐号配置接口，调用软终端功能模块中的帐号配置接口，为通话用户分配通话所需的帐号信息，以供完成通话前帐号信息的注册。The account configuration interface calls the account configuration interface in the function module of the soft terminal, and assigns the account information required for the call to the call user, so as to complete the registration of the account information before the call.

下面介绍第二个部件软终端装配模块，它设有两个子模块：浏览器适配接口和软终端功能模块，并由浏览器适配接口封装软终端功能模块而组成。所以主要完成两方面功能：第一，由软终端功能模块为该SIP软终端提供各种核心功能。第二，完成多种浏览器的适配，并配合WEB扩展业务的执行，该部分功能由包括ActiveX接口、XPCOM接口与其它接口的浏览器适配接口完成。The following introduces the second component, the soft terminal assembly module, which has two sub-modules: the browser adaptation interface and the soft terminal function module, and is composed of the browser adaptation interface encapsulating the soft terminal function module. Therefore, two functions are mainly completed: first, the soft terminal function module provides various core functions for the SIP soft terminal. Second, it completes the adaptation of various browsers and cooperates with the execution of WEB extension services. This part of the function is completed by the browser adaptation interface including ActiveX interface, XPCOM interface and other interfaces.

The hollow double-line arrows in FIG. 4 represent media links, and the single-line arrows represent signaling links.

本发明的SIP软终端被某旅游景点将其嵌入该旅游景点的主页上，为游客提供咨询业务。当游客浏览该旅游景点的主页时，可以在主页上的软终端界面上点击语音咨询按钮。通常在默认情况下，软终端经由代理服务器自动向景点客服方拨号，假设景点有如图所示的n个客服终端，每个客服终端的通话状态往往不一样，游客方的软终端首先向客服1发起呼叫，发现客服1处于忙碌状态，则软终端功能模块检测到该忙碌事件，就通过软终端扩展接口调用游客方主页中的JavaScript脚本。JavaScript脚本经过处理，调用软终端扩展接口中的“呼叫取消接口”，取消此次呼叫，转而再调用软终端扩展接口中的“发起呼叫接口”向客服2发起呼叫，如此一直下去，直到连线到第一个处于空闲状态的客服为止。假设此时的客服2处于空闲状态，于是客服2接收到游客的呼叫信息，客服2就接听呼叫，于是在游客与客服2之间建立起信令通道，接下来是启动媒体交互过程，游客与客服2开始通话。此外，游客也可以选择手动向客服方拨号，各个客服终端的代理服务器可以通过与游客方的代理服务器进行信令交换，将各个客服端的状态反馈给游客方的软终端界面，于是游客可以灵活地选择当前某一个处于空闲状态的客服端，并向该客服端发起通话请求。The SIP soft terminal of the present invention is embedded on the homepage of the tourist attraction by a certain tourist attraction to provide consulting services for tourists. When the visitor browses the homepage of the tourist attraction, he can click the voice consultation button on the soft terminal interface on the homepage. Usually by default, the soft terminal automatically dials to the customer service side of the scenic spot through the proxy server. Assuming that the scenic spot has n customer service terminals as shown in the figure, the call status of each customer service terminal is often different. Initiate a call and find that customer service 1 is in a busy state, then the soft terminal function module detects the busy event, and calls the JavaScript script in the visitor's homepage through the soft terminal extension interface. After the JavaScript script is processed, call the "call cancellation interface" in the soft terminal extension interface to cancel the call, and then call the "initiate call interface" in the soft terminal extension interface to initiate a call tocustomer service 2, and so on until the connection Line up to the first idle agent. Assuming that thecustomer service 2 is in an idle state at this time, thecustomer service 2 receives the call information of the tourist, and thecustomer service 2 answers the call, so a signaling channel is established between the tourist and thecustomer service 2, and the next step is to start the media interaction process.Customer service 2 starts talking. In addition, tourists can also choose to manually dial to the customer service side. The proxy server of each customer service terminal can exchange signaling with the proxy server of the tourist side, and feed back the status of each customer service terminal to the soft terminal interface of the tourist side, so tourists can flexibly Select a customer service terminal that is currently idle, and initiate a call request to the customer service terminal.

该实施例为游客提供景点咨询服务提供了一个非常方便的平台，在不需要手动安装通话客户端的前提下，随时可向景点客服发起咨询会话。同时，该实施例也充分体现出了本发明SIP软终端的JavaScript接口中的软终端扩展接口的优点。此处只是结合一个比较典型的应用场景来说明本发明实施例的一种工作方法，实际上，本发明的工作方法不仅仅能够面向此类场景，也可以应用于其他WEB业务，类似的工作方法都应该属于本发明的保护范围。This embodiment provides a very convenient platform for tourists to provide scenic spot consulting services, and can initiate a consulting session with scenic spot customer service at any time without manually installing a call client.
