附图概述
图 1为本发明所述终端的结构图；
图 2为本发明所述方法的流程图。
本发明的较佳实施方式
本文提出了一种终端使用业务标识信息（如业务 ID )去自动匹配从广电 网络侧搜频以后所获得的 CMCT ( Continual service Multiplex Configuration Table, 持续业务复用配置表）表内容， 以获得该业务所处的频点， 然后进行 锁频播放的方法。
本发明所述方法的基本构思是：
步骤一、 当终端判断出本地 SG 中至少有一个频点的编号值无效时， 通 过全频扫描 （即从最低的频点扫描到最高的频点， 把当前网络中所有可用的 频点信息都纪录下来）获取当前网络中的可用频点信息， 并下载各可用频点 下的 CMCT表；
按照现有协议规定， 为各频点配置的编号值应该在一个合理范围内 （如 13-49 ) , 当 SG中某个频点的编号值超出了这个范围或者该频点的编号值为 空 （如网络侧没有为该频点的编号赋值） ， 则可认为该频点的编号值无效。
在具体实现时， 在下载各可用频点下的 CMCT表后， 可将各表中的信息 提取出来， 存入同一个文件或者表内， 以便后续检索。
此外， 由于 CMCT表中保存有频点的频点编号与该频点下所有业务的业 务标识信息的对应关系， 而 SG 中也保存有该对应关系， 因此， 当终端下载 了 CMCT表后，可根据该 CMCT表中的对应关系相应地对 SG中编号值配置 无效的频点进行编号值更新， 这样就可以达到对 SG 中频点编号配置错误的 某些频点进行纠错的效果。
步骤二、 当用户从 SG选择一个业务后， 终端根据该业务的业务标识信 息在本地 SG 中查找对应的频点编号， 然后判断该查找到的频点编号值是否 有效； 若有效， 则按照现有播放流程进行处理； 若无效， 则执行步骤三； 现有播放流程包括以下步骤：
A、 终端判断当前锁定的频点与查找到的频点是否一致（即判断二者的 编号值是否相同） ， 如果一致， 则播放该业务； 如不一致， 执行步骤 B;
B、 终端重新锁频到该查找到的频点， 然后在该重新锁定的频点下执行 播放流程。
步骤三、 终端根据上述业务标识信息在本地保存的 CMCT表内容中查找 对应的频点编号， 若查找到， 则按照现有播放流程进行处理， 且还可以用该 查找到的频点编号值更新 SG中该业务对应的频点编号值，以达到对 SG纠错 的效果； 如果未查找到， 可向用户提示播放失败， 结束。
如图 1所示， 本发明所述移动终端， 包括： 人机交互界面、 控制模块、 CMMB模块及 SG模块；
控制模块设置成： 保存从网络侧 SG服务器处更新下载的 SG; 以及在收 到扫描命令后， 通过全频扫描获取当前网络中可用频点信息， 并下载各可用 频点下的持续业务复用配置表（CMCT ) ；
SG模块设置成在判断出控制模块中保存的 SG中至少有一个频点的编号 值无效时， 向控制模块发起所述扫描命令；
人机交互界面设置成向用户显示控制模块中保存的 SG; 以及当用户在其 上选定 SG中的业务后， 将该业务的标识信息通过控制模块发送给 CMMB模 块； CMMB模块设置成根据接收到的业务的业务标识信息在控制模块上保 存的 SG 中查找对应的频点编号， 并判断该频点编号值是否有效； 若无效， 则根据上述业务标识信息在 CMCT表内容中查找对应的频点编号， 并根据查 找到的频点编号按照现有播放流程进行处理。
此外， CMMB模块还可设置成在根据业务标识信息在 CMCT表内容中 查找到对应的频点编号后， 用该查找到的频点编号更新 SG 中该业务标识信 息对应的频点编号值。
控制模块还可设置成在下载 CMCT表后， 以业务标识信息为索引， 根据 所 CMCT表更新 SG中频点编号。
进一步地， 控制模块设置成通过如下方式下载每一可用频点下的 CMCT 表： 将所有可用频点对应的 CMCT表内容保存在同一个文件或者表内；
CMMB模块设置成通过如下方式根据业务标识信息在 CMCT表内容中 查找对应的频点编号： 根据业务标识信息在保存有 CMCT表内容的文件或表 内查找对应的频点编号。
下面用本发明的一应用实例进一步加以说明
如图 2所示， 本发明方法技术方案的具体实施包括以下几个步骤： 步骤 1 : 用户在终端上选择进入手机电视应用， 终端使用 PS域功能接入 IP网络后，向 SG服务器请求 SG更新； 在收到 SG服务器响应下发的 SG后， 与本地 SG进行比较后使用较新版本的 SG; 若更新失败， 则执行步骤 12; 步骤 2: 遍历 SG, 分别判断每一频道的频点编号值是否均有效， 如均有 效则执行步骤 7, 如不是均有效则执行步骤 3;
步骤 3: 在当前网络进行全频扫描， 获得当前网络中可用频点的频点编 号；
因为全频扫描一般需要 20s左右的时间， 因此如果等到用户点击播放时 才开始做全频扫描， 会导致用户等待时间较长， 这样用户体验不好。
步骤 4: 分别对所获得的各可用频点进行锁频， 记录下各频点的频点编 号和 /或频率信息；
步骤 5: 下载各可用频点的 CMCT表， 判断 CMCT列表中是否保存有该 频点的信息， 若没有则执行步骤 6, 若有则执行步骤 7;
步骤 6: 将获得的 CMCT表中的信息存入 CMCT列表中；
步骤 7: 当用户请求播放一业务时， 该终端判断该被请求的业务的频点 信息是否与当前锁频一致， 不一致则执行步骤 8, —致则执行步骤 10;
步骤 8: 终端判断该频点信息是否有效， 若有效则执行步骤 10, 无效则 执行步骤 9;
步骤 9:使用该业务的业务 ID在 CMCT列表中进行匹配， 匹配成功则从 CMCT列表中获得对应的频点编号， 然后执行步骤 10, 匹配失败则执行步骤 11 ;
步骤 10: 按照现有播放流程进行处理， 结束；
步骤 11: 播放失败， 结束；
步骤 12: 进入无 SG显示的主界面。
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的 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。
工业实用性
与现有技术相比， 釆用本发明后， 在某些地区比如县级城市， 当 SG 中 的频点信息配置错误时， 也可以正常播放业务， 因此可以给用户带来良好的 用户体验； 此外， 终端在启动后即开始检查 SG 中频点信息的正确性， 可以 节约时间。
