中国移动多媒体广播 ( CMMB , China Mobile Multimedia Broadcasting ) 系统的电子业务指南 （ ESG, Electronic Service Guide )是一项多媒体广播信 息导航业务。 终端用户通过 ESG能够获得多媒体广播业务的相关信息， 如 业务名称、 播放时间、 内容梗概等， 便于用户快速检索、 预览和访问。 ESG 为用户收看电视节目和享受信息服务提供了一个良好的导航机制， 使用户 能方便、 快捷地找到自己感兴趣的节目， 查看节目的附加信息。
ESG的这些功能成为用户观看节目的重要途径和工具。 在 ESG上可提 供多种增值业务， 以充分利用 ESG的用户群， 为运营商创造丰厚的收入。 随着 ESG信息量越来越丰富，有效地组织和调度 ESG信息便成为一项比较 重要的任务。
目前， CMMB手机电视业务中增加了很多非电视业务， 如： 股票、 信 息下载、 交通导航等。 这些业务均被集成到以往的手机电视模块中， 被统 称为移动多媒体广播业务， 用于在用户进入手机电视应用后选择使用其中 的某一项业务。 目前， 移动多媒体广播业务中所有业务的业务标识， 都存 放在 CMMB协议体系的控制信息表（承载在复用帧 0中）的持续业务复用 配置表（CMCT ) 中， 如图 la所示。
用户收看电视时， 终端通过 ESG获取节目的业务标识， 并通过 CMCT 中相应的该业务标识获取该业务对应的里德-所罗门 RS码速率、 字节交织 模式、 低密度奇偶校验码 LDPC编码速率、 调制方式、 时隙数量和时隙号 等解调信息， 以便从解调器中获取相应的数据进行处理和播放。
由于非电视业务刚刚增添到 CMMB手机电视中，与原有的手机电视业 务相比， 非电视业务的业务标识并不明确。 股票、 信息下载、 交通导航等 非电视业务的业务标识都是终端和前端发射系统口头约定的， 目前口头约 定 "2000" 为股票， "2001" 为信息下载， 而并没有书面协议规定非电视 业务的业务标识。 由于 ESG中含有移动多媒体广播业务的业务标识、 业务 名称以及节目类型 （电视节目、 广播节目等） ， 而 CMCT表中除了包含原 有的所有手机电视业务的接收解调参数外， 还包括新添的非电视业务（股 票等） 的接收解调参数， 但是 CMCT表中却没有具体业务的业务类型、 业 务名称等信息。 因此， ESG和 CMCT需要配合使用才能获取完整的移动多 媒体广播业务数据。
当前， 移动多媒体广播网络中的 ESG发射和接收系统由三部分组成： ESG服务器、 节目源发射子系统和终端。 由 ESG服务器将 ESG业务添加 到节目源发射子系统中， 并由节目源发射子系统通过逻辑信道发射 ESG, 终端通过移动多媒体广播网络接收该 ESG。
如果终端可以收到 ESG, 终端则需要等待所有的 ESG数据下载完并将 ESG解析后才能从中获知移动多媒体广播业务的业务标识、 业务类型和加 密标志等信息， 然后通过 CMCT获知业务的解调信息， 由此才能获取完整 的数据并进行处理， 最终呈现给用户。
综上， 现有的技术存在如下缺点：
( 1 )用户每次进入手机电视应用时，都要执行一遍 ESG的处理流程（本 地有 ESG, 需要对其进行解析； 本地若没有 ESG, 则需要在下载后才能解 析） ， 由此会使用户等待的时间较长， 影响用户体验。 ( 2 )由于 ESG内含有解析及播放业务数据的必要信息，终端必须将其 与 CMCT信息结合， 才能对业务数据进行正确地解析及处理。如果 ESG服 务器没有将 ESG业务添加到节目源发射子系统中， 导致 ESG未被发射； 或 者因其它某些原因导致终端接收不到 ESG, 均会使导致终端无法对业务数 据进行解析及处理。 发明内容
本发明要解决的技术问题是提供一种持续业务复用配置信息的发送方 法、 接收方法、 发送系统、 及接收终端， 能够加速移动多媒体广播业务的 处理， 以提高用户体验。 即使终端在收不到 ESG的情况下仍能获知业务数 据正确处理和播放的必要信息。

图 la为现有的 CMMB 协议体系下的 CMCT结构示意图；
图 lb为本发明对现有的 CMCT结构进行扩展的实施例结构示意图； 图 2本发明的持续业务复用配置信息的接收方法实施例的流程图； 图 3为本发明的持续业务复用配置信息的终端实施例的结构示意图； 图 4为本发明的持续业务复用配置信息的系统实施例的结构示意图。 具体实施方式
本发明为了解决传统的手机电视业务的处理方案存在的弊端， 通过在 CMCT 的基本信息中扩充各个业务的节目信息、 加密信息， 使得终端在用 户选择当前业务的业务标识时， 根据该业务标识通过 CMCT迅速获知业务 类型、 加密属性以及解调信息相应的业务信息， 并依据这些业务信息对当 前业务的业务数据进行正确地解析、 解密后， 进行后续的处理。 本发明使 终端不必等候 ESG的下载和 /或解析，就能迅速获知用户当前业务的业务类 型及加密属性等信息， 因而加速了业务的处理时间， 提高了用户体验。 并 且， 在终端接收不到 ESG的情况下， 仍能保证完整地确认当前业务是否加 密及其所属的业务类型， 以确保正确播放或使用当前业务。
以下结合附图和优选实施例进一步详细地阐述出本发明的技术方案。 以下实施例仅用于详细描述和解释本发明， 而不作为对本发明的限定。 由于现有的 CMCT表中只含有各个业务的业务标识和解调信息， 终端 无法从中获知当前业务的业务类型， 即电视节目、 广播节目、 股票、 信息 下载等， 进而无法进行各项业务数据的解析处理。 再有， 如果某项或某些 业务的数据是加密的， 终端需要调用解密模块对数据解密后， 才能调用各 个业务的处理模块进行处理。 而现有的 CMCT表中不含有加密信息， 必须 通过 ESG中获取到， 终端如果收不到 ESG, 即使获知了业务类型， 调用相 应模块处理业务时也会出错， 因为业务处理模块只能处理免费的业务数据。
因此， 本发明首先要对 CMCT信息进行扩充定义， 如图 lb所示， 譬如 在保留区扩展节目信息类、 加密信息类的信息。 这样， 在因一些原因导致 终端收不到 ESG的情况下，终端仍能根据 CMCT信息确认当前业务是否加 密， 属于何种业务类型等， 以正确播放节目或使用移动多媒体广播业务。
其中， CMCT信息除了为每个业务的节目源配置对应的业务标识及解 调信息（包括调制方式、 编码码率、 扰码方式、 字节交织模式、 时隙数量、 时隙号等）夕卜， 还扩展配置节目信息类和加密信息类。 节目信息类包括： 业务类型（手机电视节目、广播节目等）、业务名称（中央一台、河北台、 ... 等等） 、 节目分类 （体育、 娱乐等）等信息； 加密信息类包括： 加密指示 (免费服务、 付费服务等） 、 获取密钥路径（付费的路径）等信息。
虽然图 lb所示的扩展的节目信息、 保密信息是在 CMCT的保留区内， 但这仅用于解释本发明对 CMCT信息的扩展， 而不用于限定扩展区域。 在 CMCT的其它区域也可以用于本发明对节目信息、 保密信息的扩展。
本发明针对上述 CMCT的信息定义的扩充， 提供一种持续业务复用配 置信息的发送方法， 包括：
复用业务服务器根据业务的多媒体广播数据， 为各个业务配置业务信 息， 所述业务信息包括解调信息、 节目信息及加密信息， 并将各个业务的 业务标识和对应的业务信息封装在 CMCT信息中， 其中节目信息包括业务 类型、 业务名称以及业务分类等信息， 用于区分各业务的类型； 加密信息 用于指示业务数据是否加密以及对加密数据进行解密； 该复用业务服务器 通过广播网络将 CMCT信息发送给终端。 其中， 复用业务服务器是现有的 设备， 不作赘述。
相应于上述发送方法， 本发明还提供一种持续业务复用配置信息的接 收方法， 包括：
终端接收到 CMCT信息， 根据其中的业务标识读取业务信息， 该业务 信息至少包括解调信息、 节目信息及加密信息； 其中， 解调信息用于终端 接收各业务的业务数据； 节目信息用于区分各业务的类型， 以便终端据此 调用不同的业务处理模块进行处理； 加密信息则用于指示终端业务数据是 否加密以及对加密数据进行解密。
如图 2所示， 为本发明的终端接收持续业务复用配置信息的方法一实 施例的流程图， 通过该流程可以清楚地了解到本发明的传输持续业务复用 配置信息的方法的具体应用。 该流程包括以下步骤：
步骤 201 : 终端接收并解析经扩展的 CMCT数据， 即 CMCT信息。
CMCT信息除了针对每个业务配置的业务标识为节目源配置对应的解 调信息外， 还扩展配置有节目信息和保密信息。
其中，扩展的节目信息包括： 业务类型（手机电视节目、广播节目等）、 业务名称 （中央一台、 河北台、 …等等） 、 节目分类 （体育、 娱乐等）等 信息； 扩展的加密信息包括： 加密指示 （免费服务、 付费服务等） 、 获取 密钥路径 （付费的路径）等信息。
步骤 202: 终端根据 CMCT数据中的业务标识读取及解析对应的业务 信息 （包括解调信息、 节目信息及保密信息） ， 并将所有业务信息通过业 务标识作为索引保存到一个列表中。 步骤 203： 终端将该列表数据显示给用户。
步骤 204: 用户在列表数据中选择一个业务标识的链接。
步骤 205: 终端在保存的列表中查找该业务标识， 并根据该业务标识读 取出列表中相应的业务信息。
步骤 206: 终端根据业务信息中的解调信息接收该业务的业务数据。 步骤 207: 根据业务信息中的加密信息判断该业务数据是否加密， 是则 进入步骤 208执行， 否则进入步骤 209执行。
譬如加密信息中的加密指示其值为 1时表示该业务数据加密， 为 0时 表示该业务数据未加密。
实际上， 终端也可以仅根据加密信息中带有的获取密钥的路径 （即解 密信息） 判断出业务数据经过加密。
步骤 208: 根据获取密钥的路径将该业务数据进行解密， 进入步骤 209 执行。
步骤 209: 根据节目信息中的业务类型对业务数据进行后续的业务处 理， 结束流程。
当然， 终端也可以根据节目信息中的业务名称或节目分类信息识别业 务类型， 从而完成对业务数据进行后续的业务处理。

上述业务信息包括： 业务标识、 节目信息、 加密信息以及解调信息； 其中， 节目信息包括： 业务类型、 业务名称、 节目分类等信息； 加密信息 包括： 加密指示及获取密钥路径等信息； 解调信息包括里德-所罗门 RS码 速率、 字节交织模式、 低密度奇偶校验码 LDPC编码速率、 调制方式、 时 隙数量和时隙号。
显示模块 303 , 用于将接收的列表数据显示给用户， 并将用户选择的用 于链接一业务的业务标识发送给解析处理模块 302;
解密模块 304 ,用于将从解析处理模块 302接收的业务数据根据加密信 息中的获取密钥路径信息进行解密后， 发送给所述手机电视业务处理模块 305;
手机电视业务处理模块 305 , 用于根据接收的节目信息中的业务类型， 处理从解析处理模块 302接收的业务数据， 或者处理从解密模块 304接收 的经解密的业务数据， 并将处理的数据展示给用户。
当然， 手机电视业务处理模块 305也可以根据节目信息中的业务名称 或节目分类信息识别业务类型， 从而完成对业务数据进行后续的业务处理。
如图 4所示， 为本发明的持续业务复用配置信息的发送系统实施例的 结构， 该系统 400包括依次连接的手机电视业务服务器 401及复用业务服 务器 402以及终端 403 , 其中， 手机电视业务服务器 401及复用业务服务器 402组成了持续业务复用配置信息的发送前端： 手机电视业务服务器 401 ,用于发送所有的移动多媒体广播业务的多媒 体广播数据；
复用业务服务器 402 ,用于根据接收的所有的移动多媒体广播业务的多 媒体广播数据， 为所有的移动多媒体广播业务配置 CMCT数据 (即 CMCT 信息） ， 通过广播网络将 CMCT数据发送。
上述 CMCT数据包括业务标识和相应的业务信息， 业务信息包括解调 信息、 节目信息以及加密信息； 其中， 节目信息包括： 业务类型、 业务名 称及节目分类等信息； 加密信息包括： 加密指示、 获取密钥路径等信息。
综上， 本发明通过在 CMCT的基本信息中扩充节目信息、 加密信息， 使得终端仅通过 CMCT的基本信息就能迅速获知用户感兴趣的当前业务的 业务类型及加密属性， 因而大大缩短了用户使用业务的等候时间， 极大地 提高用户体验。 而且， 在因某些原因导致终端接收不到 ESG的情况下， 仍 能通过 CMCT表中的信息完整地确认当前业务的业务类型及加密属性， 从 而为用户正确处理及播放当前业务的数据。
当然， 本发明还可有其他多种实施例， 在不背离本发明精神及其实质 形， 但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
