Description
短时间业务配置表更新装置及其移动多媒体广播终端 技术领域 本发明涉及通信领域, 更具体地涉及一种短时间业务配置表更新装置, 以及应用该装置的移动多媒体广播终端。 背景技术 近年来, 数字移动多媒体广播技术和标准发展迅速, 例如欧洲的数字视 频广播手持式接收 ( Digital Video Broadcast Handheld, 简称 DVB-H ) , 美国 的媒体单一前向链路 ( Media Forward Link Only , 简称 Media FLO ) , 和中国 的移动多媒体广播 ( China Mobile Multimedia Broadcasting , 简称 CMMB )等, 为其终端用户提供了许多服务内容(如, 广告、 天气预报、 新闻、 体育节目、 综艺、 多媒体广播剧、 电影等节目 ), 用户可以根据自己的爱好选择移动多媒 体广播的服务节目。 移动多媒体广播釆用时分方式发送多媒体广播服务,其广播信道帧的持 续时间为 1秒, 由 40个 25毫秒时隙组成, 一个或多个时隙可以传送一个复 用帧封装的数据。在移动多媒体广播的复用帧结构中, 复用帧分为复用帧头、 复用帧净荷、 和复用帧填充三部分, 每个移动多媒体广播业务作为复用子帧 封装在承载业务的复用帧净荷中, 每个移动多媒体广播控制信息表作为复用 子帧封装在承载控制信息的复用子帧中, 而每个控制信息表变更指示信息则 封装在每个复用帧头中, 所以移动多媒体广播终端能及时通过复用帧头中的 相关控制信息表更新指示更新相关系统控制信息表, 从而使终端不必每次都 接收控制信息, 进而可以节约终端功耗。 短时间业务配置表是移动多媒体广播控制信息表之一,描述了本网络的 所有短时间业务与载频之间的对应关系信息, 其更新序号除了存在于复用帧 头外, 还包含于短时间业务配置表中, 所以针对终端在接收承载业务复用帧 过程中, 如何处理短时间业务配置表更新序号, 需要提供一种装置, 以使终 端及时更新短时间业务配置表信息。
发明内容 鉴于上述一个或多个问题,本发明提供了一种短时间业务配置表更新装 置。 根据本发明的短时间业务配置表更新装置,用于对承载业务复用帧中的 短时间业务配置表信息进行更新, 其包括: 解析单元, 位于终端上, 用于接 收承载业务的复用帧, 并解析复用帧的复用帧头信息, 得到特定字段; 以及 比较单元, 用于将由解析单元获得的特定字段与在终端中緩存的短时间业务 配置表中的业务配置表更新序号进行比较,并根据比较结果进行相应的处理。 其中, 在比较单元中, 还包括: 接收单元, 用于在特定字段与业务配置 表更新序号不相等时, 根据复用帧头中的控制信息表更新序号提前量指示字 段的值, 在指定的后续广播信道帧中接收控制信息复用帧; 以及更新緩存单 元, 用于更新并緩存短时间业务配置表。 其中, 特定字段为短时间业务配置 表更新序号。 根据本发明, 还提出了一种移动多媒体广播终端, 其应用了上述的短时 间业务配置表更新装置。 通过本发明, 可以保证两个短时间业务配置表更新序号的一致性。 附图说明 此处所说明的附图用来提供对本发明的进一步理解 ,构成本申请的一部 分, 本发明的示意性实施例及其说明用于解释本发明, 并不构成对本发明的 不当限定。 在附图中: 图 1是根据本发明实施例的短时间业务配置表更新装置的框图。 具体实施方式 下面参考附图, 详细说明本发明的具体实施方式。 图 1是才艮据本发明实施例的短时间业务配置表更新装置 100的框图。 参考图 1 , 说明才艮据本发明实施例的短时间业务配置表更新装置。 如图 1 所示, 该用于对承载业务复用帧中的短时间业务配置表信息进行更新的短
时间业务配置表更新装置包括: 解析单元 102, 位于终端上, 用于接收承载 业务的复用帧, 并解析复用帧的复用帧头信息, 得到特定字段; 以及比较单 元 104, 用于将由解析单元获得的特定字段与在终端中緩存的短时间业务配 置表中的业务配置表更新序号进行比较, 并根据比较结果进行相应的处理。 其中, 在比较单元 104 中, 还包括: 接收单元 1042, 用于在特定字段 与业务配置表更新序号不相等时, 根据复用帧头中的控制信息表更新序号提 前量指示字段的值, 在指定的后续广播信道帧中接收控制信息复用帧; 以及 更新緩存单元 1044, 用于更新并緩存短时间业务配置表。 其中, 特定字段为 短时间业务配置表更新序号。 在此应该理解,使用上述短时间业务配置表更新装置的多媒体广播终端 可以包括手机、 PDA、 手持终端、 以及移动电视等。 综上所述, 载业务的复用帧中只在帧头有 "短时间业务配置表更新序 号", 短时间业务配置表是否更新, 终端需要将帧头中的 "短时间业务配置表 更新序号" 与终端緩存的短时间业务配置表中的 "业务配置表更新序号" 进 行比较, 如果两个相关短时间业务的配置表更新序号不等, 则需要终端重新 接收承载控制信息的复用帧, 更新并緩存短时间业务配置表信息, 以保证两 个短时间业务配置表更新序号的一致性。 本领域技术人员将很容易了解到本发明其它优点和修改。 因此, 本发明 更广泛的方面并不限于本文中示出以及描述的特定细节和典型实施例。因此, 可在不脱离由权利要求及其等效物所限定的本发明的精神或范围的条件下做 出各种修改。
