Description

发现交互式电子业务指南的方法、服务器端和终端 Found that interactive electronic service guide method, server and terminal

技术领域 FIELD

[0001] 本发明涉及移动通信的应用层技术,特别涉及一种发现交互式电子业务指南的方法、服务器端和终端。 [0001] The present invention relates to an application layer of mobile communication technology, and particularly relates to a method for discovery of interactive electronic service guide, and a terminal server.

背景技术 Background technique

[0002] 电子业务指南(ESG)是移动通信的应用层技术中很重要的一方面,终端用户可以利用ESG方便地查看关于各种业务的资料,浏览视频频道、节目单和价格表等,选择并购买价格表中的任意一项内容,以及链接到外部网页浏览相关信息等。 [0002] Electronic Service Guide (ESG) is an application-layer technology of mobile communications is very important on the one hand, the end user can easily view the use of ESG information on various services, browse video channels, programs and price lists, etc., select and the purchase price of any of the contents of the table, as well as links to external web browsing-related information.

[0003] 目前,存在两种ESG方式,一种为广播式ESG;另一种为交互式ESG。 [0003] Currently, there are two ways ESG, one for broadcast ESG; other interactive ESG. 在广播式ESG 中,终端通过广播式ESG的自举会话进行初始化,从ESG发现信息中读取ESG提供商列表并显示给终端用户;在终端用户选择某个ESG提供商后,终端根据ESG自举会话中的ESG访问信息调协到特定的会话,接收终端用户选择的ESG提供商的ESG数据,如图1所示。 In broadcast an ESG, the terminal is initialized by the bootstrap ESG session broadcast, the information read and display a list of ESG provider from ESG discovery to the end user; after the end user selects an ESG provider from ESG The terminal For ESG session access information attuned to a specific session, receiving the ESG provider, the ESG data selected end user, as shown in FIG.

[0004] 现有技术的交互式ESG中,终端用户可以向服务器提交查询请求、用户信息(User Profile)等信息,极大丰富了ESG的功能。 Interactive ESG [0004] In the prior art, an end user may submit a query request to the server, the user information (User Profile) information, ESG functions greatly enriched.

[0005] 交互式ESG使用Web服务(Web Service)实现。 [0005] ESG interactive Web services (Web Service) implementation. Web服务是一种新的网页应用程序分支,它可以使用标准的互联网协议,如超文本传输协议(HTTP)和可扩展标识语言(XML),将功能纲领性地体现在互联网和企业内部网上。 Web services is a new branch of Web applications, it can use standard Internet protocols such as Hypertext Transfer Protocol (HTTP) and Extensible Markup Language (XML), it will be reflected in the programmatic functions of the Internet and corporate intranet. 可以将Web服务视作网页上的组件编程。 Web services can be regarded as a component programming on the page. Web服务是独立的、模块化的应用,它能够通过因特网来描述、发布、定位以及调用。 Web services are independent, modular applications that can be described by the Internet, published, located and invoked. 在Web服务的体系架构中包括三个部分:服务提供商(Service Provider)、服务请求者(Service Requestor)、服务注册器(Service Registry)。 In the Web services architecture consists of three parts: the service provider (Service Provider), the service requester (Service Requestor), service registry (Service Registry). 各部分间主要存在三个操作: 发布(Publish)、查找(Find)和绑定(Bind)。 Among some of the major presence of three things: release (Publish), Find (Find) and bindings (Bind).

[0006] Web服务本身具有完善的发现机制。 [0006] Web service itself has a complete discovery mechanism. 现有的通用描述、发现和集成(UDDI: Universal Description, Discovery, and Integration)标准对在Web 月艮务地点未知的情况下发现和使用Web服务的方法进行了说明。 Existing Universal Description, Discovery and Integration (UDDI: Universal Description, Discovery, and Integration) standard method to find and use Web services in a month that works to Web sites unknown has been explained. UDDI可以让应用程序发现和联系提供给定Web服务的服务器。 UDDI allows applications to discover and link to the server given Web service. 在终端和服务器端引入交互通道之后,终端可以通过交互通道向UDDI 服务器提交查询请求,获得特定ESG提供商的Web服务调用信息,之后终端即可根据获得的信息调用特定的Web服务。 After the introduction of the terminal and the server-side interaction channel, the terminal can be submitted through an interactive channel to the UDDI server query request, to obtain information about a particular Web service calls ESG provider, after the terminal to call a particular Web service based on the information obtained.

[0007] 图2为现有技术发现交互式ESG服务的流程图。 [0007] FIG 2 is a flowchart illustrating the prior art interactive ESG service discovery. 该流程包括以下步骤: The process comprises the steps of:

[0008] 步骤201,终端向UDDI服务器提交查询交互式ESG请求。 [0008] Step 201, the terminal requests ESG interactively submit the query to the UDDI server.

[0009] 步骤202,UDDI服务器处理接收到的查询交互式ESG请求,从自身保存的信息中获取满足查询交互式ESG请求的Web服务调用信息。 [0009] Step 202, UDDI query server processes the received interactive request ESG acquires ESG interactive call request message satisfies the query Web service from the information stored in itself.

[0010] 步骤203,UDDI服务器向终端返回交互式ESG的Web服务调用信息。 [0010] Step 203, UDDI server returns a Web service call interactive ESG information to the terminal.

[0011] 步骤204,终端解析接收到的交互式ESG的Web服务调用信息,确定向交互式ESG 提供商提交数据请求的格式。 [0011] Step 204, the Web service invocation information terminal parses the received interactive ESG determined submit a request to the interactive data format of ESG provider.

[0012] 步骤205,终端利用确定的格式向交互式ESG提供商提交数据请求。 [0012] Step 205, the terminal using the determined format to submit a request to the interactive data ESG provider.

[0013] 步骤206,交互式ESG提供商处理终端的数据请求,从自身保存的信息中获取符合终端请求的ESG数据。 [0013] Step 206, the interactive request ESG provider data processing terminal, the terminal acquires ESG data conforming to the request from the information stored in itself.

[0014] 步骤207,交互式ESG提供商向终端返回符合终端请求的ESG数据。 [0014] Step 207, the interactive ESG provider returns the ESG data requested by the terminal to meet the terminal.

[0015] 这种方案的缺点是带宽消耗不稳定,在多个用户终端同时通过交互通道向服务器端请求发现交互式ESG服务的情况下,交互通道的负载会增加。 Disadvantage [0015] This solution is not stable bandwidth consumption, in a case where a plurality of user terminals simultaneously request ESG through an interactive channel found interactive services to the server, the interaction channel load increases. 同时由于多个用户终端同时向UDDI服务器提出查询交互式ESG请求,UDDI服务器的负载会比较重。 And because a plurality of user terminals simultaneously make an inquiry request to the UDDI server interactive ESG, UDDI server load will be heavy.

[0016] 另外,不同用户终端为了发现相同的交互式ESG提供商需要分别从该交互式ESG 提供商下载相同的信息,因此会降低交互通道的使用效率。 [0016] In addition, different user terminals to find the same interactive ESG provider are required to download information from the same interactive ESG provider, thus reducing the efficiency of the interaction channel.

[0017] 现有技术中,另一种获取Web服务调用信息的技术是Web服务检查(WS-Inspection)技术。 [0017] prior art, another Web service call to obtain information technology is Web Services Inspection (WS-Inspection) technology. Web服务检查技术依靠一种完全意义上的分布模式来提供和Web服务有关的信息。 Web Services Inspection technology relies on a distributed model to provide a full sense of Web services and related information. Web服务检查技术将不同类型的ESG服务描述汇集在Web服务检查文档中, 当终端需要发现交互式ESG服务时,终端直接向存有Web服务检查文档的服务交付站点发出获取Web服务调用信息的请求;服务交付站点根据接收到的请求查询自身存有的Web服务检查文档,并按照Web服务检查规范采用既有的标准向终端返回Web服务调用信息。 Web service inspection techniques different types of ESG service description document collection in a Web service checks, when the terminal needs to find ESG interactive services, Web terminal delivery site service call issued to obtain information requests directly to the Web service there to check documents of service ; service delivery sites query Web service checks the document itself there at the request received, and the use of Web services in accordance with the existing standard specification check back Web service call information to the terminal. 所述可采用的已有标准可以为Web服务描述语言(WSDL,Web ServiceDescription Language) 等;这样,终端可以直接使用获取的Web服务调用信息,不需要进行任何修改。 The existing standards may be used as Web Services Description Language (WSDL, Web ServiceDescription Language) and the like; Thus, the terminal can directly use the acquired Web service call information, does not require any modification. 现有技术中, Web服务检查文档采用XML格式。 Art, Web services, check the document in XML format.

[0018] 这种通过Web服务检查获取Web服务调用信息的方法,必须通过交互通道从已知的服务交付点地址下载相关信息,因此会增加交互通道的负载,降低交互通道的使用效率。 [0018] Such access the Web service call information through a Web service method of examination must be delivered through an interactive channel from a known point of service address to download the relevant information, and therefore increases the load on the interactive channel, reducing the efficiency of the interaction channel.

[0019] 综上所述,现有技术中发现交互式ESG的技术方案都需要终端和服务器之间进行交互,获取Web服务的调用信息,因此会造成交互通道负载的增加,降低交互通道的使用效率。 [0019] In summary, the prior art interactive ESG find technical solutions require interaction between the terminal and the server, the call to get information about Web services, thus resulting in increased interaction channel load, reduce the use of interactive channels effectiveness.

具体实施方式 Detailed ways

[0046] 为使本发明的目的、技术方案和有益效果更加清楚明白,下面结合实施例和附图, 对本发明进一步详细说明。 [0046] For purposes of the present invention, technical solutions, and beneficial effects of more comprehensible, embodiments accompanying drawings and the following embodiments, the present invention is further described in detail.

[0047] 本发明实施例提供的发现交互式ESG服务的方法、服务器端和终端的核心思想为:服务器端在广播通道中将ESG提供商的与发现交互式ESG服务相关的信息下发给终端; 终端从广播通道中获取ESG提供商的与发现交互式ESG服务相关的信息。 The method provided in an interactive ESG service discovery embodiment of [0047] the present invention, the server and the terminal for the core idea: the discovery server and the information related to the interactive service ESG to a terminal in a broadcast channel of the ESG provider in the ; terminal acquires ESG provider from the broadcast channel information associated with the ESG discovery interactive services.

[0048] 本发明实施例提供了五种发现交互式ESG服务的方案,这五种方案中第一种、第二种以及第四种方案中与发现交互式ESG服务相关的信息为:交互式ESG的Web服务调用信息,第三种方案中与发现交互式ESG服务相关的信息为:交互式ESG的入口信息,第五种方案中与发现交互式ESG服务相关的信息为:服务器端下交互式ESG的Web服务调用信息的传输会话的入口信息。 [0048] Example embodiments of the present invention provides five interactive ESG service discovery protocol, five in the first embodiment, second embodiment and the fourth service found in the interactive ESG-related information: Interactive Web service invocation of ESG information, and found that the third option in the interactive service related information for ESG: ESG interactive entry information, the fifth program in the ESG found that interactive services which are: interaction at the server side ESG-style entrance information service information transfer session invoked the Web.

[0049] 本发明实施例提供的第一种发现交互式ESG服务的方案为:服务器端在每一个提供商的发现信息中扩展识别交互式ESG的标识,通过广播通道将每一个Web服务调用信息作为一个传输对象下发给终端。 [0049] The first embodiment provides an interactive ESG discovery service embodiment of the present invention are: interactive server identification extension identifier in each ESG provider discovery information, the broadcast channel by each of the Web service invocation information as a next transport object to the terminal. 终端在确定用户选择了交互式ESG服务时,在广播通道获取Web服务调用信息。 When the terminal determines that the user selected the interactive ESG service, access to the Web service call information in a broadcast channel.

[0050] 图3为本发明发现交互式ESG服务方法的一个较佳实施例的流程图,该流程包括如下步骤: [0050] Figure 3 a flowchart of a method interactive ESG service discovery preferred embodiment of the present invention, the process comprising the steps of:

[0051] 步骤301,服务器端在每一个ESG提供商的ESG发现信息中扩展交互式ESG的标识。 [0051] Step 301, the server identification information of the interactive extension of the ESG in the ESG each ESG provider discovery.

[0052] 服务器端的ESG发现信息中包含多个ESG提供商的发现信息,每一个ESG提供商的ESG发现信息中包括:ESG提供商的名称、ESG提供商的编号(Provider ID)以及ESG提供商的其他附属信息等。 ESG [0052] server discovery information includes a plurality of ESG provider discovery information of an ESG each ESG provider discovery information includes: the name of an ESG provider, an ESG provider ID (Provider ID) and ESG provider the other subsidiary information.

[0053] 如果ESG提供商只支持交互式ESG服务,或只支持广播式ESG服务时,服务器端在该ESG提供商的发现信息中扩展交互式ESG标识,标识该ESG是交互式还是广播式ESG。 [0053] If ESG ESG provider only supports interactive services, or ESG supports only broadcast service, interactive ESG server side extension identifies the ESG provider discovery information, the identification of the ESG is interactive or broadcast ESG .

[0054] 服务器端的每一个ESG提供商的访问信息包括:与ESG发现信息关联的ESG提供商的编号、下发ESG数据的IP地址和端口以及传输会话标识等。 Access information for each ESG provider [0054] server comprises: an ESG provider and ESG discovery information associated with the ID, issued by the ESG data and the IP address and port transmission session identifier and the like.

[0055] 如果ESG提供商即支持交互式ESG,又支持广播式ESG,则服务器端不仅需要在ESG 发现信息中扩展交互式ESG标识,用于表示对应的ESG服务是交互式还是广播式,还需要在ESG访问信息中扩展交互式ESG的入口信息的标识,用于表示对应的ESG传输会话入口信息是在交互式ESG中使用还是在广播式ESG中使用。 [0055] If the provider is to support interactive ESG ESG, ESG and support for broadcast, the server-side only need to find information in the ESG extended interactive ESG identifier is used to indicate the corresponding interactive service or ESG broadcast, also extended access information required entry identification information in an interactive ESG ESG, ESG for indicating a transmission session using information corresponding to the entry in the ESG or an interactive broadcast using the ESG.

[0056] 步骤302,服务器端通过广播通道,在ESG自举会话中向终端广播ESG发现信息和ESG访问信息,同时在另外的传输会话中向终端广播与每一个交互式ESG服务对应的Web服务调用信息。 [0056] Step 302, the server through a broadcast channel, discovery information and broadcast information to the terminal access ESG ESG in the ESG bootstrap session, while the additional transmission session to the terminal with a broadcast service corresponding to each interactive Web service ESG call information.

[0057] 所述传输会话可以使用FLUTE等协议作为传输协议。 The [0057] FLUTE transmission session and the like may be used as transport protocol. 将每一个Web服务调用信息作为一个传输对象通过传输会话向终端广播,在一个传输会话中可以传输一个传输对象, 也可以传输多个传输对象。 Each of the Web service invocation information to the terminal as a broadcast transport object, in a transmission session may be transmitted via a transmission session transport object, a plurality of transport objects may be transmitted.

[0058] 如果服务器端通过一个传输会话向终端广播多个ESG服务对应的Web服务调用信息,则终端只通过该传输会话的入口信息将无法确定哪一个传输对象为自身需要的Web服务调用信息。 [0058] If the server call message to the terminal through a broadcast transmission session ESG services corresponding to a plurality of Web service, only the terminal which is unable to determine a transport object itself as a Web service invocation information needed by the entry information of the transmission session.

[0059] 为了使终端在下发交互式Web服务调用信息的传输会话中能够快速确定地获取所需的Web服务调用信息,服务器端可以预先生成Web服务调用信息的索引信息,并将该索引信息作为一个独立的传输对象在同一个传输会话中与Web服务调用信息一起广播给终端。 [0059] In order to make the next terminal sent an interactive Web service call session information transmission can be determined quickly access the information needed to call the Web service, the server may generate index information Web service invocation information in advance, and the index information as a separate transport object in the same transport session with the Web service invocation information broadcast to the terminal together.

[0060] 该索引信息中至少需要包含如下信息:交互式ESG提供商的编号(Provider ID) 和传输对象编号,所述的传输对象编号标识传输一个完整的Web服务调用信息的传输对象。 [0060] The index information needs to include at least the following information: the number of interactive ESG provider (Provider ID) and the transmission object number, object number identification transmission of the transmission of a complete Web service invocation information transfer object.

[0061] 同时,服务器端需要在传输Web服务调用信息的传输会话中,标识传输对象承载的是索引信息还是Web服务调用信息。 [0061] Meanwhile, the server needs to transfer Web service call session information transmission, the target identification transmission bearer information is an index or a Web service invocation information. 这样,终端在接收自身需要的Web服务调用信息前, 根据索引信息标识来判断承载索引信息的传输对象,从中读取索引信息,并根据从索引信息中读取的承载自身所需的Web服务调用信息所在的传输对象的编号,到相应的传输对象中读取Web服务调用信息。 Thus, before the terminal receiving the Web service invocation information needed itself, determines the index information identifying a transport object carrying the index information, the index information is read from, and according to the bearer's own Web service calls required to read information from the index No transmission of information where the object, reads the Web service call information to the corresponding transmission object. 以下所述的调用信息均指Web服务调用信息。 Call information below refer to the Web service call information.

[0062] 终端通过使用索引信息可以快速获取调用信息,是因为调用信息通常比较小,只有几百个字节,因此服务器端通过广播通道向终端轮播索引信息的周期会比轮播Web服务调用信息的周期短,进而使终端可以快速准确地从广播通道获取所需要的Web服务调用信息。 [0062] terminal by using the index information can call to obtain information quickly, because the call information is usually relatively small, only a few hundred bytes, so the server through a broadcast channel information to the terminal carousel index cycle will be broadcast over the Web service call round the short cycle information, thereby enabling the terminal to quickly and accurately obtain the required Web service invocation information from the broadcast channel. [0063] 较佳地,Web服务调用信息用WSDL标准描述,即使用WSDL文件存储Web服务调用信息。 [0063] Preferably, the Web service invocation information described in WSDL standards, i.e. use of a WSDL file stored in the Web service invocation information.

[0064] 步骤303,终端启动,从ESG自举会话广播的ESG发现信息中读取ESG提供商列表, 显示给用户。 [0064] Step 303, the terminal starts, the session from the ESG from the ESG cited broadcast discovery information read ESG provider list displayed to the user.

[0065] 步骤304,当终端根据用户选择的ESG提供商确定选择交互式ESG时,从ESG自举会话广播的ESG访问信息中读取下发对应的ESG提供商的Web服务调用信息的会话入口信息。 [0065] Step 304, when the terminal according to the determined ESG provider selected by the user selecting interactive ESG, read session information entry Web service call issued by the corresponding ESG provider from ESG ESG access information from a broadcast session held in information. [0066] 该步骤包括如下过程:终端记录用户选择的ESG提供商的编号;如果确定该ESG 提供商能够支持交互式ESG,且终端确定选择交互式ESG时,根据记录的提供商编号从ESG 访问信息中获取下发Web服务调用信息的传输会话入口信息。 [0066] The process comprises the following steps: the user terminal records the selected ESG provider ID; determining if the ESG provider can support interactive ESG, the terminal determines and selected interactive ESG, ESG from access provider according to the number of records obtaining information issued by the Web service call information transmission session entry information.

[0067] 这里,终端可以根据记录的ESG提供商的编号对应的ESG发现信息中的交互式ESG 标识确定该ESG提供商是否能够提供交互式ESG,如果能够,则终端可以根据是否已开通交互通道服务、或交互通道信号的强弱等信息确定选择交互式ESG服务方式还是广播式ESG 服务方式。 [0067] Here, the terminal can find the interactive ESG identification information to determine whether an ESG provider can provide interactive ESG, if so, whether the terminal can be opened in accordance with an interaction channel according to the corresponding number of recording ESG ESG provider services or other interactive channel signal strength information is determined to select an interactive service mode or ESG ESG broadcast service.

[0068] 步骤305,终端根据读取的传输会话入口信息,调协到所述下发ESG提供商的Web 服务调用信息的传输会话。 [0068] Step 305, the transmission terminal according to the session information entry read, issued attuned to the ESG provider Web service call session information transmission.

[0069] 步骤306,终端从所述下发Web服务调用信息的传输会话中读取Web服务调用信息。 [0069] Step 306, a terminal issued from the Web service call session information transmission reads the Web service invocation information. [0070] 如果在所述传输会话中只传输一个Web服务调用信息的传输对象,则终端可以直接从该传输会话中获取Web服务调用信息; [0070] The transmission of a Web service call subject information transmitted only in the transmission session, the terminal can be transmitted directly from the Web service call session information;

[0071] 如果所述传输会话中传输多个Web服务调用信息的传输对象以及封装索引信息的传输对象,则终端根据索引信息标识来判断承载索引信息的传输对象,从中读取索引信息,并根据从索引信息中读取的承载自身所需的Web服务调用信息所在的传输对象的编号,到相应的传输对象中读取Web服务调用信息。 [0071] If the transport object and transmitting the index information object encapsulates a plurality of Web service invocation information transmitted in said transmission session, the terminal determines the index information identifying a transport object carrying the index information, the index information is read from, and in accordance with carrier index information read from their desired transport object ID Web service invocation information resides, reads the Web service invocation information into the corresponding transport object.

[0072] 步骤307,终端解析获取的Web服务调用信息,获得调用交互式ESG服务的Web服务所需的信息。 [0072] In step 307, the terminal analyzing data acquired Web service call information, call the interactive ESG access to information services required for Web services.

[0073] 以上步骤实现了发现ESG服务的目的,当终端获取到Web服务调用信息后,执行以下步骤从交互式ESG提供商获取符合自身要求的ESG数据:终端通过交互通道向交互式ESG提供商提交数据请求;交互式ESG提供商处理接收到的数据请求,生成结果数据;交互式ESG提供商通过交互通道返回符合终端数据请求的ESG数据。 [0073] found that the above steps to achieve the purpose of ESG services, after acquiring the terminal information to a Web service call, perform the following steps to obtain ESG data in line with their own requirements from an interactive ESG provider: an interactive terminal through an interactive channel to ESG provider Submit request data; interactive data processing request received ESG provider to generate result data; interactive ESG provider through an interactive channel return data line with a terminal requests the ESG data.

[0074] 图4为图3所示实施例的一种实现方式的流程图。 [0074] As shown in FIG. 4 is a flowchart of one implementation of the embodiment of FIG. 该实现方式中设定终端所需要的ESG服务的提供商只支持交互式ESG或只支持广播式ESG,并且服务器端在一个传输会话中向终端广播多个Web服务调用信息的传输对象,设定Web服务调用信息为WSDL文件,传输会话为FLUTE会话,该流程包括如下步骤: The implementation required setting terminal ESG provider supports only services or supports only an interactive broadcast ESG ESG, and the server call message in one transmission session to the terminal broadcast transmission of a plurality of Web service object set Web service call information to the WSDL file transfer session is a FLUTE session, the process comprising the steps of:

[0075] 步骤401,服务器端在每一个ESG提供商的ESG发现信息中扩展交互式ESG标识, 为每一个WSDL文件传输对象编号,构造在一个传输会话中传输对象的索引信息,并在承载索引信息的传输对象中扩展一个传输对象属性标识,用于标识该传输对象承载的是索引信息还是WSDL文件。 [0075] Step 401, each server-side ESG in the ESG provider discovery information in an interactive extension ESG identifier number, index information of an object of transmission is configured for each transport object in a WSDL file transfer session, and the carrier index extended information transfer object a transport object identifier attribute, used to identify the transport object carrying the index information or the WSDL file.

[0076] 在现有技术中,ESG发现信息由ESGProviderDiscovery描述符承载,ESG访问信息由ESGAccessDescriptor 描述符承载。 [0076] In the prior art, ESG discovery information carried by the ESGProviderDiscovery descriptor, ESG access descriptor carries information from the ESGAccessDescriptor.

[0077] 在ESGProviderDiscovery描述符中,每个ESG提供商由一个服务提供商元素描述,该元素的类型是ESGProviderType。 [0077] In ESGProviderDiscovery descriptor, each ESG provider, a service provider is described by the element, the element type is ESGProviderType. 为了让终端能够判断一个ESG服务是交互式还是广播式,本发明在ESGProviderType中扩展了一个字段,用于表示对应的ESG服务是交互式还是广播式,将该字段命名为InteractiveESG标识,如表1所示。 In order for a terminal can be determined ESG or an interactive broadcast service, the present invention extends in ESGProviderType in a field used to indicate the corresponding ESG or an interactive broadcast service, the field named InteractiveESG identifier, as shown in Table 1 Fig. 在表1中类型El表示表中所有元素为ESGProviderType的第一层元素。 In Table 1 Type El represents the table all elements of the first layer of the element ESGProviderType.

[0079]表 1 [0079] TABLE 1

[0080] 服务器端在每一个ESG提供商的发现信息中扩展交互式ESG标识,还可以通过在每一个ESG提供商的提供商名称ProviderID字段中取出一个比特来作为交互式ESG标识位,用于表示对应的ESG服务是交互式还是广播式。 [0080] The ESG server interactive extension identifies each ESG provider discovery information may also be removed by a bit as a flag in the interactive ESG provider ProviderID name field of each ESG provider, for indicates that the corresponding interactive service or ESG broadcast.

[0081] 一个传输会话中传输的WSDL文件传输对象的索引信息的结构如表2所示。 [0081] The structure of the index information in the WSDL file of a transmission session transfer object transmitted as shown in Table 2. 该索引信息中包括=WSDL文件的个数、交互式ESG提供商的编号以及每一个传输对象的编号。 This information includes the index number = WSDL file, the interactive ESG provider ID number, and each transport object. 各个字段的数据类型都是无符号整数、高位优先。 The data type of each field is an unsigned integer, the high priority.

[0084]在 FLUTE 协议的FDT-Instance XML Schema 中,根元素FDT-Instance 包含多个File元素,每个File元素描述一个传输对象。 [0084] In the FDT-Instance XML Schema FLUTE protocol, the root element FDT-Instance File includes a plurality of elements, each element describes a File Transfer Object. 每个File元素包含一个可任意扩展的anyAttribute 属性。 Each element contains a File optionally anyAttribute extensible properties.

[0085] 如果一个传输对象传输的是WSDL文件,则不扩展描述该传输对象的File元素的anyAttribute属性;如果一个传输对象传输的是索引信息,则扩展描述该传输对象的File 元素的anyAttribute属性。 [0085] If the transmission is a transport object WSDL file, no extended attributes described anyAttribute File element of the transport object; object transmission if a transmission is the index information, the extended attributes described anyAttribute File transfer element of the object.

[0086] 对于传输索引信息的传输对象,将对应的File元素的anyAttribute属性扩展为: InteractiveESGIndex = Ture0 [0086] For the transmission of the transmission-subject index information, anyAttribute File attribute extension of the corresponding elements is: InteractiveESGIndex = Ture0

[0087] 图5为图4所示方式将WSDL文件通过一个传输会话下发给终端的示意图。 [0087] FIG. 5 is shown in FIG. 4 by the WSDL file transfer session a schematic view of a next terminal sent. 从图中可见,索引信息作为一个单独的传输对象下发给终端,并且该传输对象由扩展的FDT属性InteractiveESGIndex 标识。 Seen from the figure, the index information as a separate transport object to the terminal, and by the extension of the FDT transport object identifier attribute InteractiveESGIndex.

[0088] 步骤402,服务器端通过广播通道在ESG自举会话中将ESG发现信息和ESG访问信息广播给终端;在另一个传输会话中将每一个WSDL文件作为一个传输对象,并将索引信息作为一个单独的传输对象向终端广播。 [0088] Step 402, the server through a broadcast channel access information and ESG discovery information to the broadcasting terminal in the session in ESG bootstrap ESG; another in a transmission session for each WSDL file as a transfer object and the index information as a single broadcast transmission to the target terminal.

[0089] 步骤403,终端启动,从ESG自举会话广播的ESG发现信息中读取ESG提供商列表, 显示给用户。 [0089] Step 403, the terminal starts, the session from the ESG from the ESG cited broadcast discovery information read ESG provider list displayed to the user.

[0090] 步骤404,终端记录用户选择的ESG提供商的提供商编号。 [0090] Step 404, the user selects an ESG provider ID of the provider terminal records.

[0091] 步骤405,终端根据记录的提供商编号确定选择广播式ESG时,按照广播式ESG的规范处理,结束流程;确定选择交互式ESG时,执行步骤406。 [0091] Step 405, the terminal number is recorded is determined according to the provider selected ESG broadcast, broadcast processing according to the ESG specification, the flow is terminated; interactive selection is determined ESG, step 406 is performed.

[0092] 这里,终端可以根据ESG提供商发现信息中的交互式ESG标识来确定选择广播式ESG,还是交互式ESG。 [0092] Here, the interactive terminal may ESG identification information is determined to select broadcast ESG, ESG or an interactive found that the ESG provider.

[0093] 步骤406,终端根据记录的提供商编号从ESG自举会话广播的ESG访问信息中读取下发对应的ESG提供商的WSDL文件的会话入口信息,包括IP地址和端口号。 [0093] Step 406, the terminal number recording session entry information provider issued the corresponding read ESG provider from ESG ESG access information from a broadcast session held in the WSDL file, including the IP address and port number according to.

[0094] 步骤407,终端调协到步骤406读取的入口信息对应的传输会话。 [0094] Step 407, the terminal step 406 to attune transmission session information corresponding to the read entry.

[0095] 步骤408,终端在步骤407所述传输会话中接收带有扩展属性InteractiveESGIndex的传输对象,从中读取索引信息。 [0095] Step 408, the terminal receives the transmission with the target in the extended attribute InteractiveESGIndex transmission session in step 407, the index information is read therefrom.

[0096] 步骤409,终端从索引信息中读取与提供商编号对应的传输对象编号。 [0096] Step 409, the terminal is read from the index information provider ID number corresponding to the transfer object.

[0097] 步骤410,终端从传输会话中获取与读取的传输对象编号一致的传输对象,从而获取所需的WSDL文件。 [0097] Step 410, the terminal acquires the transmission session read from the same object number is transmitted transport object, so as to obtain the desired WSDL file.

[0098] 图6为图3所示实施例的另一种实现方式的流程图。 [0098] As shown in FIG. 6 is a flow chart of another implementation manner of the embodiment of FIG. 该实现方式中设定终端所需要的ESG服务的提供商即支持交互式ESG,又支持广播式ESG,并且服务器端在一个传输会话中向终端广播多个Web服务调用信息的传输对象,设定Web服务调用信息为WSDL文件, 传输会话为FLUTE会话,该流程包括如下步骤: The implementation required setting terminal ESG provider support interactive services, i.e. ESG, ESG and broadcast support, and the server call message in a broadcast transmission session to the terminal a plurality of Web service transport object, set Web service call information to the WSDL file transfer session is a FLUTE session, the process comprising the steps of:

[0099] 步骤601,服务器端在每一个ESG提供商的ESG发现信息中扩展交互式ESG标识, 在ESG访问信息中扩展交互式ESG传输会话入口信息标识,并构造在一个传输会话中传输的WSDL文件传输对象的索引信息,并在承载索引信息的传输对象中扩展一个传输对象属性标识。 [0099] Step 601, each server-side ESG in the ESG provider discovery information identification extended interactive ESG, ESG transport extended interactive session identifier information in the ESG entry access information, and configured in a transmission session WSDL transmitted an index information file transport object and a transport object extended attribute identifies the transport object carrying the index information.

[0100] 服务器端采用表1所示的方式在ESGPr0ViderType中扩展交互式ESG标识,采用表2所示的方式构造索引信息,并且采用与图4所示实现方式相同的方法传输索引信息的传输对象中扩展File 元素的anyAttribute 属性,即InteractiveESGIndex = True。 [0100] server by way of expansion shown in Table 1 in the interactive identification ESGPr0ViderType the ESG, constructed using the index information shown in Table 2, using the transfer object and achieve the same manner as FIG method for transmitting the index information shown in FIG. 4 extended File elements anyAttribute property, namely InteractiveESGIndex = True.

[0101] 同时,本实现方式还在ESGAccessDescriptor中扩展一个AccessMethod字段,用于区别提供商编号相同的两条访问信息中的传输会话入口信息是交互式ESG使用的还是广播式ESG使用的。 [0101] Meanwhile, the present embodiment also achieve a AccessMethod ESGAccessDescriptor extended field for the same transport session information entry number difference between two access provider information is used or interactive ESG ESG broadcast use. 在该实现方式中,从保留字段中取出一个比特作为AccessMethod标志位,保留字段从原来的6比特减少为5比特。 In this implementation, the reserved field is removed from a flag bit as AccessMethod, reserved field is reduced from the original 6 bits is 5 bits.

[0102] 如表3和表4所示,表3为ESGAccessDescriptor的结构;表4为在ESGEntry内扩展AccessMethod 字段。 [0102] As shown in Table 3 and Table 4, Table 3 ESGAccessDescriptor structure; Table 4 AccessMethod extension field within ESGEntry.

[0103]<table>table see original document page 11</column></row> <table>[0104]表 3 [0103] <table> table see original document page 11 </ column> </ row> <table> [0104] TABLE 3

[0105]<table>table see original document page 11</column></row> <table>[0106] 表4 [0105] <table> table see original document page 11 </ column> </ row> <table> [0106] TABLE 4

[0107] 步骤602,服务器端通过广播通道在自举会话中将ESG发现信息和ESG访问信息广播给终端;在另一个传输会话中将每一个WSDL作为一个传输对象,并将索引信息作为一个单独的传输对象向终端广播。 [0107] Step 602, the server through a broadcasting channel from the ESG session will give access discovery information and ESG information broadcast to the terminal; in another transmission in the session for each WSDL as a transmission object and the index information as a separate the transport object to the broadcasting terminal.

[0108] 步骤603,终端启动,从ESG自举会话广播的ESG发现信息中读取ESG提供商列表, 显示给用户。 [0108] Step 603, the terminal starts, reads the information provider list ESG, ESG displayed to the user from an ESG bootstrap session broadcast discovery.

[0109] 步骤604,终端记录用户选择的ESG提供商的提供商编号。 [0109] Step 604, the user selects an ESG provider ID of the provider terminal records.

[0110] 步骤605,终端根据记录的提供商编号确定选择广播式ESG时,按照广播式的规范处理,结束流程;确定选择交互式ESG时,执行步骤606。 [0110] Step 605, the terminal number is recorded is determined according to the selected provider broadcast the ESG, the broadcast processing according to the specifications, the end of the process; it is determined that the ESG interactive selection, step 606 is performed.

[0111] 这里,终端可以根据是否已开通交互通道服务、或交互通道信号的强弱等信息确定选择交互式ESG服务方式还是广播式ESG服务方式。 [0111] Here, the terminal may determine or select an interactive service mode ESG ESG broadcast service mode according to whether the service interaction channel opening, or other interactive channel signal strength information.

[0112] 步骤606,终端根据用户选择的ESG提供商的提供商编号从ESG自举会话广播的ESG访问信息,即ESGAccessDescriptor中根据AccessMethod读取下发对应的ESG提供商的交互式ESG的WSDL文件的会话入口信息,包括IP地址和端口号。 [0112] Step 606, the terminal number of the user according to the selected ESG provider, an ESG provider from ESG bootstrap information accessed broadcast session, i.e. a WSDL file in accordance AccessMethod ESGAccessDescriptor read interactive ESG ESG provider issued the corresponding the session entry information, including the IP address and port number.

[0113] 步骤607,终端调协到该传输会话。 [0113] Step 607, the terminal attuned to the transmission session.

[0114] 步骤608,终端在传输会话中接收带有扩展属性InteractiveESGIndex的传输对象,从中读取索引信息。 [0114] Step 608, the terminal receives the transmission with the target in the extended attribute InteractiveESGIndex transmission session, the information read from the index.

[0115] 步骤609,终端从索引信息中读取与提供商编号对应的传输对象编号。 [0115] Step 609, the terminal is read from the index information provider ID number corresponding to the transfer object.

[0116] 步骤610,终端从传输会话中获取与读取的传输对象编号一致的传输对象,从而获取所需的WSDL文件。 [0116] Step 610, the terminal acquires the transmission session read from the same object number is transmitted transport object, so as to obtain the desired WSDL file.

[0117] 本发明实施例提供的第二种发现ESG服务的方案为:用容器封装调用信息文件, 将每个容器作为一个传输对象通过广播通道在传输会话中广播给终端。 A second embodiment of the provided [0117] The present inventors have found that ESG services to the program: the call information file package container, each container as a transmission target terminal in a transmission to the broadcast session through a broadcast channel. 每个容器可以封装一个或多个子结构,每个子结构封装一个Web服务调用信息文件或索引信息文件。 Each container may be packaged one or more sub-structures, each sub-structure of the package a Web service invocation information file or index information file.

[0118] 如果一个容器中只封装一个子结构,即只封装一个Web服务调用信息文件,并且在一个传输会话中只传输一个容器,则不需要构造索引文件;如果一个容器封装多个子结构,或/和在一个传输会话中传输多个容器,则需要构造索引信息文件,每个子结构封装一个Web服务调用信息文件或索引信息文件。 [0118] If only one container a substructure package, i.e. a package only Web service call information file, and transmits only a container in a transport session, the need to construct an index file; if a plurality of sub-packaging container structures, or / and transmission of a plurality of containers in a transport session, the information necessary to construct the index file, each sub-structure of the package a Web service invocation information file or index information file. 在传输会话中,每个容器由唯一的容器编号标识,在每个容器内,每个子结构由唯一的子结构编号标识。 In the transmission session, each identified by a unique container ID of the container, in each container, each of the sub-structures by a unique identification number of the sub-structure.

[0119] 图7为本发明发现交互式ESG服务方法的第二个较佳实施例的流程图。 [0119] FIG 7 a second preferred embodiment of a flowchart of the interactive ESG service discovery method of the present invention. 该流程包括以下步骤: The process comprises the steps of:

[0120] 步骤701,服务器端在每一个ESG提供商的ESG发现信息中扩展交互式ESG标识, 并将调用信息封装在固定结构的容器中。 [0120] Step 701, each server-side ESG in the ESG provider discovery information in an interactive ESG identifier extension, and the call information is encapsulated in a container fixed structure.

[0121] 一个容器可以只封装一个调用信息,也可以封装多个调用信息。 [0121] a container can only package a call message, the package may be a plurality of call information. 如果在一个容器中封装多个调用信息,每个调用信息封装在容器的一个子结构中。 If the call information a plurality of packaging containers, each call a sub-structure information is encapsulated in the container. 容器的管理信息包含在容器的头部结构中。 Management information contained in the header structure of the container vessel. 容器头需要包含如下信息:子结构封装的文件类型;子结构的编号, 这个标号在一个容器内是唯一的;子结构封装的文件的起始位置;子结构封装的文件的长度;子结构封装的文件的版本信息。 Container header contains the following information needed: package file type substructure; numbered sub-structure, this label is unique within a container; beginning of the file of the sub-structure of the package; the file length of a sub-structure of the package; package substructure file version information.

[0122] 当一个容器中封装多个调用信息时,为快速定位Web服务调用信息所在的容器和子结构,服务器端生成调用信息的索引信息,并将索引信息封装在一个独立的容器中,在传输会话中和调用信息一起下发给终端。 [0122] When a plurality of packaging container when calling information, and to quickly locate the container substructure Web service invocation information is located, the server generating the index information in the call, and the index information is encapsulated in a separate container, the transmission session next to the terminal and call information together.

[0123] 索引信息中至少需要包含如下信息:交互式ESG提供商的编号;调用信息文件所在的容器编号;调用信息文件所在的子结构编号。 [0123] the index information needs to include at least the following information: an interactive ESG provider ID; No call information file container is located; substructure call number information file. 将索引信息文件单独封装在一个容器中可以保证索引信息所在容器足够小,从而使得终端可以快速读取索引信息。 The index information file individually packaged in a container where the container can ensure that the index information is sufficiently small, so that the terminal can quickly read the index information.

[0124] 如果ESG提供商即支持交互式ESG,又支持广播式ESG,则服务器端不仅需要在ESG 发现信息中扩展交互式ESG的标识,用于表示对应的ESG服务是交互式还是广播式,还需要在ESG访问信息中扩展交互式ESG的传输会话入口信息的标识,用于表示对应的ESG传输会话入口信息是在交互式ESG中使用还是在广播式ESG中使用。 [0124] If the provider is to support interactive ESG ESG, ESG and support for broadcast, the server-side only need to find information in Extensible Markup interactive ESG in the ESG, ESG is used to represent the corresponding service is interactive or broadcast, also need access to the information identification transmission session entry information in the extended interactive ESG ESG, ESG for indicating a transmission session using information corresponding to the entry in the ESG or an interactive broadcast using the ESG.

[0125] 步骤702,服务器端通过广播通道在自举会话中将ESG发现信息和ESG访问信息广播给终端;在另一个传输会话中将每一个封装有Web服务调用信息的容器作为一个传输对象广播给终端。 [0125] Step 702, the server through a broadcasting channel from the ESG session will give access discovery information and ESG information broadcast to the terminal; another transmission in the session in a package container each Web service invocation information as a broadcast transport object to the terminal.

[0126] 如果有封装索引信息的容器,则将封装索引信息的容器作为一个单独的传输对象向终端广播。 [0126] If there is the index information package container, the container will be packaged as a single index information is transmitted to the target terminal broadcasts.

[0127] 步骤703,终端启动,完成初始化,在ESG自举会话中为用户显示ESG提供商列表。 [0127] Step 703, the terminal starts, initialization is complete, the bootstrap ESG session displayed to the user in the ESG provider list.

[0128] 步骤704,终端记录用户选择的ESG提供商的提供商编号。 [0128] Step 704, the user selects an ESG provider ID of the provider terminal records.

[0129] 步骤705,终端根据记录的提供商编号确定选择交互式ESG时,执行步骤706 ;如果终端确定选择广播式ESG时,则按照现有技术的广播式规范处理,结束流程。 When [0129] Step 705, the terminal number is recorded is determined according to provider the ESG interactive selection, step 706 is performed; if the terminal is determined to select the ESG broadcast, the broadcast specifications according to the prior art process, the process ends.

[0130] 这里,终端可以根据记录的ESG提供商的编号对应的ESG发现信息中的交互式ESG 标识确定该ESG提供商是否能够提供交互式ESG,如果能够,则终端可以根据是否已开通交互通道服务、或交互通道信号的强弱等信息确定选择交互式ESG服务方式还是广播式ESG 服务方式。 [0130] Here, the terminal can find the interactive ESG identification information to determine whether an ESG provider can provide interactive ESG, if so, whether the terminal can be opened in accordance with an interaction channel according to the corresponding number of recording ESG ESG provider services or other interactive channel signal strength information is determined to select an interactive service mode or ESG ESG broadcast service.

[0131] 步骤706,终端根据记录的提供商编号,从ESG访问信息中获取下发Web服务调用信息的传输会话入口信息。 [0131] Step 706, the terminal number is recorded in accordance with the provider, the access information transmitted from the ESG acquisition session entry information delivering Web service invocation information.

[0132] 步骤707,终端调协到由该IP地址和端口号确定的传输会话。 [0132] Step 707, the terminal attuned to transport session determined by the IP address and port number.

[0133] 步骤708,终端在调协到的传输会话中获取封装Web服务调用信息的容器,从中获得所需得Web服务调用信息。 [0133] Step 708, the terminal obtains the packaged Web service invocation information is attuned to a transport session, which have to obtain a desired Web service invocation information.

[0134] 如果在一个容器中封装了多个Web服务调用信息,并且服务器在传输会话中将封装索引信息的容器下发给终端,则终端步骤708包括如下过程: [0134] If a plurality of packages in a Web service invocation information container, and the server to the terminal at the container transfer session index information in the package, the terminal 708 includes the following process steps:

[0135] 终端根据容器头信息识别封装索引信息的容器,并读取传输会话中调用信息文件的索引信息;终端根据记录的提供商编号从读取的索引信息中获得对应的容器编号和子结构编号;终端根据获得的容器编号在传输会话中获取封装有所需调用信息的容器,再根据获得的子结构编号,从该容器中获得所需的Web服务调用信息。 [0135] The container of the container terminal identification information package header index information, and reads the index called transmission session information files; container terminal to obtain corresponding number from the index number and the sub-structure in accordance with the information provider reads the recorded number ; container terminal number obtained in the transmission session according to the acquired package container necessary call information, then according to the sub-structure number obtained, the Web service calls to obtain the desired information from the container.

[0136] 图8为图7所示实施例的一种实现方式的流程图,该实现方式中调用信息由WSDL 标准描述,即使用WSDL文件存储Web服务的发现和调用信息,并且设定一个容器中封装多个WSDL文件。 [0136] FIG 8 is a flowchart of one implementation of the embodiment shown in FIG. 7, this implementation described by WSDL standards call information, i.e., information used to find and invoke the Web service WSDL file storage, and a container set encapsulating the plurality of WSDL files. 传输协议使用FLUTE。 Transfer Protocol using FLUTE. 该流程包括如下步骤: The process comprises the steps of:

[0137] 步骤801,服务器端在每一个ESG提供商的ESG发现信息中扩展交互式ESG标识, 并将WSDL文件封装在固定结构的容器中,构造WSDL文件的索引信息,封装在单独的容器中。 [0137] Step 801, each server-side ESG in the ESG provider discovery information in an interactive ESG identifier extension, and the WSDL file packaged in a container fixation structure, the index information configured WSDL file, packaged in separate containers .

[0138] 如果ESG提供商只支持交互式ESG,或只支持广播式ESG,则服务器端采用表1所示的方式在每一个ESG提供商的ESG发现信息中扩展交互式ESG标识;如果ESG提供商即支持交互式ESG,又支持广播式ESG,则服务器端不仅需要采用表1所示的方式在每一个ESG 提供商的ESG发现信息中扩展交互式ESG标识;还需要采用表2所示的方式在每一个ESG提供商的ESG访问信息中扩展交互式ESG的传输会话入口信息的标识。 [0138] If ESG ESG provider only supports interactive, broadcast, or only support ESG, the server side shown in Table 1 by way of each ESG in the ESG provider discovery information in an interactive extension ESG identifier; if the ESG provided i.e. supports interactive ESG providers, and supports broadcast ESG, the server need not shown in table 1 for each ESG in the ESG provider discovery information in an interactive extension ESG identifier; need further shown in table 2 interactive way to expand the ESG in the ESG access information of each ESG provider identification transmission session entry information.

[0139] 服务器端将WSDL文件封装在容器中,容器的结构可以如表5和表6所示,各字段的数据类型都是无符号整数、高位优先(uimsbf,即unsignedinteger,most significant bit first)。 [0139] The WSDL file server packaged in a container, the container structure can be as shown in Table 5 and table, the data type of each field in Figure 6 are unsigned integers, high priority (uimsbf, i.e. unsignedinteger, most significant bit first) . 表5为容器的结构,表6为表5所示容器中struCture_type字段的取值范围和含义。 Table 5 shows the structure of the container, and Table 6 is a table range and meaning of the container shown in Figure 5 struCture_type field.

[0140] 在传输会话中,每个容器作为一个传输对象传输,通过FDT-Instance中的一个File元素进行描述。 [0140] In the transmission session, each container object transmission as a transmission, is described by one FDT-Instance File element. File元素中的contentjocation属性唯一标识每个容器,其中包含了容器的编号;COntent_type属性表明容器中承载的内容的类型。 contentjocation File attribute uniquely identify each element in the container, containing the number of the container; CONTENT_TYPE attribute indicates the type of content carried in the container.

[0146] 为快速定位Web服务调用信息文件所在的容器和子结构,定义表7所示的索引信息。 [0146] index information to quickly locate and container substructure Web service call information files are located, the definition shown in Table 7. 表7中各字段的数据类型都是无符号整数、高位优先(uimsbf,即unsigned integer, most significant bit first)。 Table 7 data type of each field are unsigned integers, high priority (uimsbf, i.e. unsigned integer, most significant bit first). 将索引信息单独封装在一个容器中可以保证索引信息所在容器足够小,从而使得终端可以快速读取索引信息。 The index information is individually packaged in a container where the container can ensure that the index information is sufficiently small, so that the terminal can quickly read the index information.

[0147] 从表7可见,封装WSDL文件的索引信息的容器中包含如下信息:本容器承载的WSDL文件的个数、交互式ESG提供商的编号、承载描述该交互式ESG的WSDL文件的容器编号、在容器内承载WSDL文件的子结构编号。 [0147] seen that the container package index information in the WSDL file from Table 7 contains the following information: the number of the container carrier according to the WSDL file, the interactive ESG provider ID, the carrier container described WSDL file of the interactive ESG numbers bearing substructure WSDL file number in the container. 将索引信息文件单独封装在一个容器中可以保证索引信息所在容器足够小,从而使得终端可以快速读取索引信息。 The index information file individually packaged in a container where the container can ensure that the index information is sufficiently small, so that the terminal can quickly read the index information.

[0250] 上述实施例提供的五种发现ESG服务的方案中,服务器端通过广播通道在ESG自举会话中向终端下发ESG发现信息和访问信息前,进一步可以包括如下步骤:服务器端在ESG的发现信息和/或访问信息中,指示相关的广播式ESG和交互式ESG之间的关系。 [0250] The embodiment provides five ESG discovery programs and services, the server side in the ESG bootstrap session before the discovery information and the access information sent to the terminal through a broadcast channel ESG, may further comprise the step of: in the ESG server the discovery information and / or access information indicating the correlation relationship between the broadcast and interactive ESG ESG.

[0251] 广播式ESG和相关的交互式ESG之间的关系是指二者传输的数据范围之间的关系,以下列举出二者之间的几种关系: [0251] The relationship between the ESG and broadcast-related interactive ESG refers to the relationship between the data transmission range of both, include some of the following relationship between the two:

[0252] 1)广播式ESG传输主要数据,交互式ESG根据用户的请求传输附加数据。 [0252] 1) primary broadcast ESG transport data, interactive ESG transport additional data according to a user's request. 此时称广播式ESG附带交互式ESG,交互式ESG补充广播式ESG。 At this point, he said broadcast ESG comes with interactive ESG, ESG supplemental interactive broadcast ESG.

[0253] 2)广播式ESG传输一部分主要数据,交互式ESG传输另一部分主要数据,两者传输的数据组成一个完整的ESG。 [0253] 2) a portion of the primary broadcast ESG transport data, the other main part of the interactive ESG transport data, both the data transmission to form a complete ESG. 此时称广播式ESG和交互式ESG之间为并列关系; [0254] 3)广播式ESG和交互式ESG传送完全相同的数据。 In this case known as the parallel relationship between the broadcast and interactive ESG ESG; [0254] 3) broadcast and interactive ESG ESG transfer exactly the same data. 此时称广播式ESG和交互式ESG之间为拷贝关系。 At this time, it is known as copy relationship between broadcast and interactive ESG ESG.

[0255] 4)广播式ESG传输完整的ESG数据,交互式ESG传输一部分ESG数据。 [0255] 4) a complete ESG broadcast transmitting ESG data, the interactive part of the transmission ESG ESG data. 此时称广播式ESG和交互式ESG之间为部分拷贝关系。 At this time copy relationship between said portion of broadcast and interactive ESG ESG.

[0256] 关于交互式ESG和相关的广播式ESG的关系还有很多种,这里没有完全列举出来。 [0256] The interactive relationship between ESG and ESG-related broadcast there are many, there is no fully listed. 为描述简单起见,可以用设定的编号表示交互式ESG与相关的广播式ESG之间的关系。 For simplicity of illustration, to indicate the relationship between the interactive ESG ESG broadcast associated with the set number. 表13中给出了一种用编号表示交互式ESG与相关的广播式ESG之间关系的具体实现方式: Table 13 shows the specific implementation of the interactive relationship between a representation associated with the ESG ESG broadcast by number:

[0268] 在实际应用中,可以只在ESG发现信息或访问信息中指示交互式ESG与相关的广播式ESG的关系,也可以同时在ESG发现信息和访问信息中指示交互式ESG和相关的广播式ESG的关系。 [0268] In practical applications, it can be found only in the ESG information or access information indicating an interactive relationship with the associated ESG broadcast an ESG, may be simultaneously in the ESG discovery information and access information indicating associated broadcast and interactive ESG ESG's relationship.

[0269] 如果采用表9或表10所示的任意一种方式在ESG访问信息中扩展交互式ESG的入口信息,则还可以在表9或表10中进一步增加指示交互式ESG和相关的广播式ESG的关系的字段,具体实现可以采用与如表15中从NumOfRelatedESG至Value To的语法部分相同的方式。 [0269] If any one of the embodiment shown in Table 9 or Table 10 using entry access information in extended interactive ESG ESG, it may further increase instruction associated broadcast and interactive ESG in Table 9 or Table 10 the ESG field type relationship, as seen from the specific implementation to NumOfRelatedESG Value to syntax table section 15 may be employed in the same manner.

[0270] 当在ESG发现信息或访问信息中指示该ESG与相关的ESG之间的关系时,终端通过交互式通道向交互式ESG提交数据请求前,进一步包括如下步骤: Before [0270] When the discovery information in the ESG or the access information indicates a relationship between the ESG ESG-related, terminal data request to submit an interactive ESG through an interactive channel, further comprising the steps of:

[0271] 如果终端确定用户选择交互式ESG,则终端根据该交互式ESG的发现信息或访问信息确定该交互式ESG与相关的广播式ESG的关系。 [0271] If the terminal determines that the user to select an ESG, the terminal determines that the interactive relationship with the associated ESG broadcast discovery information according to the ESG or the access information of the interactive ESG. 之后,终端根据确定的该交互式ESG 与相关的广播式ESG的关系,确定要请求的数据是否在该交互式ESG的数据范围内。 Thereafter, the terminal according to the determined relationship associated with the interactive broadcast ESG ESG, determining whether the data to be requested in the data range of interactive ESG. 如果确定是,则终端向交互式ESG提供商发出数据请求;如果确定否,则终端不再向交互式ESG 的提供商发出数据请求,流程结束。 If it is determined that the terminal issues a data request to the interactive ESG provider; if not determined, the terminal is no longer issuing a data request to the interactive ESG provider, the flow ends.

[0272] 如果终端确定用户选择广播式ESG,则终端根据该广播式ESG的发现信息或访问信息确定该广播式ESG与相关的交互式ESG的关系,然后再按照广播式ESG的规范进行处理。 [0272] If the terminal determines that the user selected broadcast ESG, the terminal of the ESG broadcast discovery information or access information for determining the relationship with the interactive broadcast ESG according to the ESG-related, then processed in accordance with the ESG broadcast specifications.

[0273] 本发明同时还提供了一种发现交互式电子业务指南服务的系统,该系统包括:月艮务器端和终端,其中服务器端包括:发现交互式ESG服务相关信息发送模块,该模块用于通过广播通道向终端下发ESG提供商的与发现交互式ESG服务相关的信息; [0273] The present invention also provides an interactive electronic service guide system discovery and services, the system comprising: a month that works to end and a terminal, wherein the server comprises: an interactive ESG service discovery information transmitting module, the module It found that ESG for an interactive service information associated with a broadcast channel to send through the ESG provider in the terminal;

[0274] 终端包括发现交互式ESG服务相关信息接收模块,用于在广播通道获取所述ESG 提供商的与发现交互式ESG服务相关的信息。 [0274] ESG interactive terminal comprises a discovery service-related information receiving module, configured to obtain information related to the ESG provider and ESG discovery interactive broadcast service channel.

[0275] 前面所述的实施例提供的发现交互式ESG的方法都是首先获取交互式ESG的调用信息,然后再根据该调用信息携带的交互式ESG服务能力信息,向交互式ESG服务器提交数据请求,获得ESG数据。 [0275] The previously described embodiments provide interactive ESG discovery method is interactive information first obtains the ESG call, and then submit the data to the interactive ESG ESG server according to the service capability information of the interactive information carried in the call request to obtain ESG data. 在实际应用中,也可以直接从交互式ESG服务器获得ESG数据,不必首先获得ESG的调用信息。 In practical applications, it can also be obtained directly from the interactive ESG ESG data server, without having to first obtain call information of the ESG. 比如,在ESG多会话机制中,就可以实现直接与交互式ESG服务器交互获得ESG数据。 For example, in multi-session ESG mechanism, you can get direct interaction with the interactive ESG ESG data server. ESG多会话机制中,ESG服务提供的ESG数据被分成多个ESG集合在不同的会话中传输。 Multi-session mechanism ESG, ESG ESG data is divided into a plurality of services provided by a set of ESG transmission in different sessions.

[0276] ESG服务提供的ESG数据的划分通过分割声明(Partition Declaration)信息描述。 [0276] dividing ESG ESG data services provided by dividing the description statement (Partition Declaration). 终端从ESG自举会话中获取ESG自举信息,ESG自举信息中包括ESG发现信息和ESG 访问信息。 Terminal acquires ESG bootstrap session from the ESG bootstrap information, ESG bootstrap information, ESG discovery information includes access information and ESG. ESG访问信息中包括多会话传输标识信息和分割声明信息的获取地址。 ESG access information, including multi-session transmission identification information and access to information statements divided address. 终端根据用户选择的提供商从ESG自举信息中获取相应的多会话传输标识(Multiple Stream Transport)信息,确定采用多会话机制时,从ESG自举信息的ESG访问信息中获取分割声明信息的获取地址。 Terminal obtains corresponding multi-session transmission identifier (Multiple Stream Transport) ESG bootstrap information from the information provider according to user selection, the multi-session mechanism determines, from the ESG bootstrap ESG access information division information acquired claim information acquiring address. 现有技术中ESG服务提供的ESG数据划分成的多个ESG集合都通过广播式ESG会话提供,在ESG自举会话中携带的只有广播式ESG会话的地址。 ESG ESG data services provided in the prior art is divided into a plurality of collections are available through ESG ESG broadcast session, only the broadcast address ESG session carried in the ESG bootstrap session.

[0277] 本发明实施例对ESG多会话机制进行扩展,通过在Partition Declaration信息中为每一个ESG集合增加访问类型信息,标识其携带的是交互式ESG会话地址,还是广播式ESG会话地址。 Embodiment [0277] embodiment of the present invention, multiple ESG session mechanism is extended by increasing the access type information set to each of the one ESG Partition Declaration information, identifies which is carrying interactive session address ESG, ESG session or a broadcast address. 这里的交互式ESG会话地址可以为交互式URL。 Here's an interactive ESG interactive session may address URL. [0278] 图14为本发明发现交互式ESG服务方法的第六个较佳实施例的流程图,该流程包括如下步骤: [0278] FIG 14 a sixth preferred embodiment of a flowchart of the interactive ESG service discovery method of the present invention, the process comprising the steps of:

[0279] 步骤1401,终端启动,完成初始化,获取ESG自举信息,为用户显示ESG提供商列表。 [0279] Step 1401, the terminal starts, initialization is completed, acquire ESG bootstrap information, ESG provider list displayed for the user.

[0280] 这里,ESG自举会话是通过广播网络建立的广播会话,ESG自举会话中包括ESG发现信息和ESG访问信息。 [0280] Here, ESG bootstrap session is established through a broadcasting network session, includes ESG bootstrap session in ESG ESG discovery information and access information. 本实施例中,ESG访问信息中携带有用于标识是否采用ESG多会话机制的多会话传输标识,以及分割声明信息的获取地址。 In this embodiment, it carries ESG access information for identifying whether a multi-session transport mechanism of the multi-session ESG identifier, and obtain the address information division statements. [0281] 步骤1402,终端记录用户选择的ESG提供商的提供商编号。 [0281] Step 1402, the terminal records the number of the user selected ESG provider provider.

[0282] 步骤1403,终端根据记录的ESG提供商编号从ESG发现信息中获取多会话传输标识,判断是否采用多会话机制,如果采用,则执行步骤1404 ;否则按照未采用多会话机制的发现交互式ESG的方法执行后续过程,比如可以采用前述实施例所提供的发现交互式ESG 的方法。 [0282] Step 1403, the terminal number is recorded according to the ESG provider information acquired from the multi-session transport ESG identifier discovery, the mechanism determines whether the multi-session, if employed, execute step 1404; otherwise not found in accordance with the interactive multi-session mechanism the method of performing subsequent processes ESG formula, such as the method provided in the foregoing embodiment may be employed found that ESG interactive.

[0283] 步骤1404,终端根据记录的ESG提供商编号从ESG访问信息中获取Partition Declaration信息的获取地址,从该获取地址获取Partition Declaration信息。 [0283] Step 1404, the terminal acquires ESG Partition Declaration information from the access information according to the acquired ESG provider ID recorded address, the address acquisition acquisition Partition Declaration information.

[0284] 步骤1405,终端自身选定或终端根据用户或服务器端的选择选定获取的Partition Declaration信息中记载的一个ESG集合。 [0284] Step 1405, the terminal or the terminal itself selected according to a user selected acquisition server or a selected set of ESG Partition Declaration information is described.

[0285] 步骤1406,终端根据Partition Declaration信息中携带的选定ESG集合的访问类型信息判断通过交互式ESG服务,还是广播式ESG获取该ESG集合,如果是交互式ESG服务,则执行步骤1407 ;如果是广播式ESG服务,则执行步骤1408。 [0285] Step 1406, the terminal acquires the ESG ESG ESG through an interactive set of services, or broadcast information according to the access type determination Partition Declaration information carried in the selected set of ESG, ESG if the interactive service, execute step 1407; If it is broadcast ESG service, step 1408. .

[0286] 步骤1407,终端根据从Partition Declaration信息中获取的交互式ESG地址信息,从交互式ESG服务器获取选定的ESG集合,执行步骤1409。 [0286] Step 1407, the interactive terminal according to the address information obtained from the ESG Partition Declaration information, acquired from the selected set of interactive ESG ESG server, step 1409.

[0287] 步骤1408,终端根据从Partition Declaration信息中获取的广播式ESG地址信息,从广播式ESG获取选定的ESG集合。 [0287] Step 1408, broadcast terminal according to the address information obtained from the ESG Partition Declaration information, acquired from the selected ESG ESG broadcast set.

[0288] 步骤1409,终端判断是否已处理完Partition Declaration信息中记载的所有ESG集合,如果处理完,则结束流程;否则,返回步骤1406。 [0288] Step 1409, the terminal determines whether the processed set of all ESG Partition Declaration information is described, if processed, the process ends; otherwise, returns to step 1406.

[0289] 终端在获取到每一个ESG集合之后,会判断接收到的ESG集合是否具有一致性,只有具有一致性的ESG集合才能被终端解析并提供给用户。 [0289] After acquiring the terminal to each of a set of ESG, receiving an ESG determines whether the collection has a consistency just consistent set of ESG can be parsed and provided to the user terminal.

[0290] 所谓ESG集合是否具有一致性的判断的原则是:该ESG集合所引用的所有信息是否都包含在终端已获取的ESG集合中,如果是,则认为该ESG集合具有一致性,可以将该ESG 集合解析并提供给用户;否则,认为该ESG集合不具有一致性,终端继续接收后续的ESG集合,直到接收到的所有ESG集合所引用的信息均已接收到时,将已接收到的ESG集合解析提供给用户。 Principle [0290] The so-called ESG consistency determination whether the collection is: whether all ESG information of the referenced collection set contained in the ESG terminal has acquired, if that is considered consistent set of ESG, may be parsing the ESG set and provided to the user; otherwise, that the ESG set is not consistent, the terminal continues to receive a subsequent set of ESG, when all the information until the received ESG set referenced been received, which has been received ESG collection resolve to the user.

[0291] 通常,终端对获取的ESG集合的一致性判断都是在终端获取到该ESG集合之后,将该ESG集合的特征信息与已接收到的ESG集合的特征信息进行比较来判断的,这个过程较为复杂,为了能够简化终端判断接收到的ESG集合的一致性的过程,本发明实施例中提供了如下实现方式: After [0291] Generally, the terminal determines consistency of the acquired ESG set to the ESG set is acquired in the terminal, wherein the characteristic information with the set of ESG information has been received by comparing the set of ESG determination, the process is more complex, in order to simplify the process of consistency terminal determines an ESG received set of embodiments provides the following embodiments of the invention implemented:

[0292] 首先服务器端在创建分割声明信息时,确定该分割声明信息中记载的ESG集合提供给终端的顺序,并为每一个ESG集合增加一个一致性标识。 [0292] First, the server-side declaration information when creating the division, the division determining a set of ESG information statement described in order to provide a terminal and an ESG to a consistent increase in each set of identification. 比如可以设定一致性标识为0 表示该ESG集合与之前所获取的所有ESG集合合并后是不一致的,即该ESG集合所引用的信息不能在之前已获取的ESG集合中全部获得,或之前已获取的ESG集合所引用的信息不能从该ESG中获得;一致性标识为1表示该ESG集合与之前已获取的ESG集合合并后是一致的,即该ESG和之前获取的所有ESG集合所引用的信息均可从当前已获取的ESG集合中得到。 May be set before such consistency identified as 0 represents that all the previous ESG ESG set of the acquired combined set is inconsistent, i.e., the set of ESG information is not referenced in the set of all previously acquired ESG, or ESG set information referenced acquired can not be obtained from the ESG; and identified as a consistency before a rear set of the acquired ESG ESG combined set is consistent, that is, the previously acquired ESG ESG and the set of all cited information can be obtained from the collection of ESG currently acquired.

[0293] 终端在获取终端选定的Partition Declaration信息中记载的一个ESG集合前,需要按照服务器端确定的顺序获取该ESG集合之前的每一个ESG集合。 [0293] ESG before a terminal set forth in acquiring the terminal selected Partition Declaration information need to be obtained prior to the collection of each of the ESG ESG server set in the order determined. 终端获取到一个ESG集合时,首先根据该ESG集合的一致性标识确定该ESG集合的一致性。 When the terminal acquires a set of ESG, an ESG is first set to determine identity identifying an ESG in accordance with the consistency of set.

[0294] 如果一致性标识为1,终端获取该ESG集合,将该ESG集合与之前获取的未提供给用户的ESG集合一并解析并展示给用户。 [0294] If the consistency is identified as 1, the terminal acquires the ESG set, the set of previously acquired ESG is not provided to the user together with the set of ESG parsed and presented to the user.

[0295] 如果一致性标识为0,终端获取该ESG集合后,不作处理,继续获取下一个ESG集 [0295] If the consistency is identified as 0, the terminal acquires the ESG set, no treatment, continue to obtain the next set of ESG
