应当理解, 此处所描述的实施例仅仅用以解释本发明, 并不用于限定 本发明。
本发明实施例为了节约网络资源, 在两平台间增设数据存储器和数据 緩冲器。 本发明实施例中两平台间传输的数据信息, 根据流程的不同, 其 传输的数据信息不同。 在数据同步流程中, 其传输的数据信息为同步数据 流水, 该同步数据流水包括: 同步业务数据、 同步业务数据对应的流水号 和生效标志。 生效标志可以为即时生效标志和定时生效标志。
在数据重发流程中, 由源平台向数据緩冲器传输的数据信息为待重发 的同步数据流水对应的流水号。 由数据緩冲器向目标平台传输的数据信息 为待重发的同步数据流水, 该待重发的同步数据流水包括: 待重发的同步 业务数据、 该待重发的同步业务数据对应的流水号和生效标志。 该生效标 志可以为即时生效标志和定时生效标志。
在数据冲正流程中, 传输的数据信息包括: 冲正标志、 待冲正的同步 数据流水对应的流水号。
以下是本发明实施例的数据信息的传输方法一实施例, 参见图 2, 其包 括如下步骤:
步骤 S201、 源平台向数据緩冲器发送同步数据流水, 并判断是否发送 成功; 当发送成功, 则转入步骤 S202; 当发送失败, 则转入步骤 S203; 步骤 S202、 数据緩冲器将同步数据流水发送给目标平台;
步骤 S203、 源平台将同步数据流水发送给数据存储器进行存储。
进一步地, 参见图 3 , 上述步骤 S202包括: 步骤 S301、 数据緩冲器将同步数据流水发送给目标平台, 判断是否发 送成功; 当发送失败, 则转入步骤 S302; 当发送成功, 则结束流程。
步骤 S302、 数据緩冲器将同步数据流水发送给数据存储器进行存储, 然后转入步骤 S303 ;
步骤 S303、 数据緩冲器定时从数据存储器提取同步数据流水, 并将定 时提取的同步数据流水发送给目标平台, 直至将定时提取的同步数据流水 成功发送给目标平台; 然后转入步骤 S304;
步骤 S304、 数据存储器删除定时提取的发送成功的同步数据流水。 因为目标平台已接收到同步数据流水, 不再需要数据緩冲器定时从数 据存储器中提取并发送同步数据流水, 因此, 删除该同步数据流水。 另外 删除数据存储器中已发送成功的同步数据流水, 可以释放数据存储器的存 储空间, 为后续流程提供数据存储空间。
本实施例, 当源平台向数据緩冲器发送同步数据流水发送成功, 然后 由数据緩冲器向目标平台发送同步数据流水失败时, 通过数据緩冲器定时 从数据存储器中提取同步数据流水, 并将提取的同步数据流水发送给目标 平台, 直至发送成功, 在保证同步数据流水发送成功率的基础上, 减少了 同步数据流水的传输次数, 从而节约了大量的网络资源。
本发明实施例的数据緩冲器, 根据实际需要预先设有用于控制数据緩 冲器从数据存储器中提取同步数据流水的时间周期参数, 数据緩冲器当向 目标平台发送同步数据流水失败后, 根据该设定的时间周期参数定时在设 定的周期后从数据存储器提取同步数据流水, 然后再发送给目标平台, 直 到发送成功为止。 数据緩冲器向目标平台发送同步数据流水失败的原因可 能是目标平台暂时繁忙或出现故障, 一段时间后由繁忙转为空闲或故障消 除, 此时再向目标平台发送同步数据流水, 可以减少同步数据的传输次数, 因而减少两平台间同步数据的传输量, 从而节约了大量的网络资源。 进一步地, 参见图 4 , 源平台向数据緩冲器发送同步数据流水失败, 为 保证同步数据流水的不丟失, 数据緩冲器定时从数据存储器中提取之前发 送失败的同步数据流水,并发送给目标平台,其流程在上述实施例步骤 S203 后, 还包括:
步骤 S401、 数据緩冲器根据预先设定的定时周期参数, 定时从数据存 储器中提取同步数据流水;
步骤 S402、 数据緩冲器将定时提取的同步数据流水发送给目标平台, 直到将定时提取的同步数据流水成功发送给目标平台;
步骤 S403、 数据存储器删除定时提取的发送成功的同步数据流水。 本实施例, 当源平台向数据緩冲器发送同步数据流水发送失败时, 通 过数据緩冲器定时从数据存储器中提取同步数据流水, 并将提取的同步数 据流水发送给目标平台, 直至发送成功, 在保证同步数据流水发送成功率, 同时减少了同步数据流水的传输次数, 从而节约了大量的网络资源。 进一步地, 参见图 5 , 源平台向数据緩冲器发送同步数据流水失败, 目 标平台急需该发送失败的同步数据流水, 则需要源平台重发该同步数据流, 该重发的过程在上述步骤 S203之后, 还包括:
步骤 S501、 源平台向数据緩冲器发送待重发的同步数据流水对应的流 水号;
步骤 S502、 数据緩冲器根据流水号从数据存储器提取待重发的同步数 据流水, 并将待重发的同步数据流水发送给目标平台;
步骤 S503、 数据存储器删除发送成功的待重发的同步数据流水。
上述重发过程中, 只需向数据緩冲器发送待重发的同步数据流水对应 的流水号, 数据緩冲器根据流水号从数据存储器中提取待重发的应同步数 据流水, 然后再发送给目标平台。 无需再次向数据緩冲器发送待重发的同 步数据流水, 减少了源平台与数据緩冲器间数据传输量, 因而更进一步节 约了网络资源, 进一步地, 参见图 6, 目标平台接收到同步数据流水后, 还包括以下处 理:
步骤 S601、判断同步数据流水中包含定时生效标志还是即时生效标志; 当包含定时生效标志,转入步骤 S602;当包含即时生效标志,转入步骤 S606; 步骤 S602、 将同步数据流水中的同步业务数据和流水号保存至临时数 据模块;
步骤 S603、 提取临时数据模块中的流水号和正式数据模块中待更新的 业务数据, 并将该流水号和待更新的业务数据保存至历史数据模块中; 步骤 S604、 提取临时数据模块中的同步业务数据, 并使用该同步业务 数据更新正式数据模块中待更新的业务数据;
步骤 S605、 删除临时数据模块中的同步业务数据和流水号;
本步骤删除同步业务数据为了防止目标平台定时从临时数据模块提取 待冲正的同步数据流水中的同步业务数据, 然后将该同步业务数据更新到 正式数据模块中。
步骤 S606、 提取接收到的同步数据流水中的流水号和正式数据模块中 待更新的业务数据, 并将该流水号和待更新的业务数据一同保存至历史数 据模块;
步骤 S607、 使用接收到的同步数据流水中的同步业务数据更新正式数 据模块中待更新的业务数据。
进一步地, 上述同步数据流水还包括有非冲正标志, 目标平台接收到 同步数据流水后, 首先查询同步数据流水中包含非冲正标志还是冲正标志, 当同步数据流水中包含非冲正标志, 则执行上述步骤 S601至步骤 S607。 进一步地, 本发明实施例的数据信息的传输方法的实施例中, 源平台 向数据緩冲器发送同步数据流水后, 发现该发送的同步数据流水是错误的 , 为了保证目标平台中的被更新后的业务数据的正确性, 对错误的同步数据 流水进行冲正, 参见图 7, 步骤如下:
步骤 S701、 源平台判断待冲正的同步数据流水是否成功发送给数据緩 冲器; 当发送成功, 则转入步骤 S702; 当发送失败, 则转入步骤 S705; 步骤 S702、 源平台向数据緩冲器发送冲正标志、 待冲正的同步数据流 水对应的流水号;
步骤 S703、 数据緩冲器将冲正标志、 待冲正的同步数据流水对应的流 水号发送给目标平台;
步骤 S704、 目标平台根据冲正标志查找与流水号对应的待冲正的同步 数据流水, 并对待冲正的同步数据流水进行冲正;
步骤 S705、 源平台向数据存储器发送冲正标志和待冲正的同步数据流 水对应的流水号;
步骤 S706、 数据存储器根据冲正标志查找与流水号对应的待冲正的同 步数据流水, 并对待冲正的同步数据流水进行冲正。
本步骤的对应待冲正的同步数据流水进行冲正的操作为: 将数据存储 器中待冲正的同步数据流水删除。 用以释放数据存储器的数据存储空间。 并防止数据緩冲器定时从数据存储器提取待冲正的同步数据流水, 并发送 给目标平台, 有效地防止数据的发送错误。 进一步地, 参见图 8, 本发明实施例提出的数据信息的传输方法的上述 实施例中, 数据存储器对待冲正的同步数据流水进行冲正的步骤为:
步骤 S801、 数据存储器删除待冲正的同步数据流水, 判断是否删除成 功; 当删除失败, 则转入步骤 S802; 当删除成功, 则结束流程;
本步骤中, 数据存储器将待冲正的同步数据流水删除, 可以及时释放 数据存储器的数据存储空间。 同时可以防止数据緩冲器定时从数据存储器 提取并向目标平台发送该待冲正的同步数据流水。 因此可以减少数据的发 送错误。
当删除失败, 则表明数据存储器中的同步数据流水通过数据緩冲器定 时提取, 成功发送给目标平台, 并在发送给目标平台后成功删除同步数据 流水。
步骤 S802、 源平台向数据緩冲器发送冲正标志, 待冲正的同步数据流 水对应的流水号;
步骤 S803、 数据緩冲器将冲正标志、 待冲正的同步数据流水对应的流 水号发送给目标平台;
步骤 S804、 目标平台根据冲正标志查找与流水号对应的待冲正的同步 数据流水, 并对待冲正的同步数据流水进行冲正。
本步骤中的对待冲正的同步数据流水进行冲正的步骤在上述实施例已 详细描述, 在此不再赘述。 进一步地, 参见图 9 , 上述目标平台对待冲正的同步数据流水进行冲正 的流程包括:
步骤 S901、 根据冲正标志查找临时数据模块中是否存在与流水号对应 的待冲正的同步数据流水; 当不存在待冲正的同步数据流水, 则转入步骤 S902; 当存在待冲正的同步数据流水, 则转入步骤 S904;
步骤 S902、 根据流水号提取历史数据模块中与流水号一同存储的业务 数据;
本步骤将提取的流水号和待更新的业务数据一同存储至历史备份数据 库中, 是为了防止当源平台发送的同步业务数据错误, 通过流水号查找该 待更新的业务数据, 将该待更新的业务数据重新更新正式数据库中错误的 同步业务数据, 该错误的同步业务数据为源平台之前发送的同步业务数据。
步骤 S903、 将提取的业务数据更新正式数据模块中待冲正的同步业务 数据;
本步骤中的待冲正的同步业务数据, 为源平台发送的同步数据流水中 的同步业务数据, 该待冲正的同步业务数据更新了目标平台源的业务数据, 该待冲正的同步业务数据是错误的数据, 其冲正操作为: 用目标平台原有 的业务数据更新该待冲正的同步业务数据。
步骤 S904、 删除临时数据模块中待冲正的同步数据流水。
进一步地, 在上述冲正流程中传输的数据信息除了冲正标志和流水号, 还包括即时生效标志, 目标平台收到数据信息后, 还需查看是否含有即时 生效标志, 若有则根据该即时生效标志立即对待冲正的同步数据流水进行 冲正处理。
上述冲正过程中, 目标平台接收到的数据信息包括: 冲正标志、 待冲 正的同步数据流水对应的流水号和即时生效标志, 不携带具体的同步业务 数据, 减少了数据的传输流量, 因而节约了大量的网络资源。 本发明实施例的数据信息的传输方法, 适用于多种网络系统, 例如应 用于移动多媒体广播业务系统中广电平台和移动业务平台间的同步数据的 传输, 此时, 源平台为移动多媒体广播业务系统中的广电平台, 目标平台 为移动多媒体广播业务系统中的移动业务平台, 源平台向目标平台发送的 数据信息包括有: 流水号, 冲正标志、 生效标志。 数据同步流程中发送的 数据信息还包括具体的业务数据。 以下为移动多媒体广播业务系统中广电 平台向移动业务平台传输同步数据流水的程序代码:

数据緩冲器 30, 还用于将冲正标志、 待冲正的同步数据流水对应的流 水号发送给目标平台 20。
目标平台 20, 还用于根据冲正标志查找与流水号对应的待冲正的同步 数据流水, 并对待冲正的同步数据流水进行冲正。
目标平台 20对待冲正的同步数据流水进行冲正的过程为: 根据冲正标 志查找临时数据库中是否存在与流水号对应的待冲正的同步数据流水, 当 存在待冲正的同步数据流水, 则删除临时数据库中待冲正的同步数据流水。 当不存在待冲正的同步数据流水, 则根据流水号从历史备份数据库中, 查 找与该流水号一同存储的业务数据; 提取查找到的业务数据, 并将该业务 数据更新正式数据库中待冲正的同步数据。
上述查找的业务数据, 为目标平台 20源有的业务数据, 在目标平台 20 的正式数据库中原有的该业务数据, 之前已被源平台 10传输来的同步业务 数据更新。

进一步地, 目标平台 20, 还用于查询接收的数据信息是否包含即时生 效标志, 根据即时生效标志对待冲正的同步数据流水进行即时冲正处理。
源平台 10向数据緩冲器 30发送数据信息, 再由数据緩冲器 30发送给 目标平台 20的的数据信息只包括: 冲正标志、 待冲正的同步数据流水对应 的流水号和即时生效标志, 不包括具体的同步业务数据。 因此可以减少数 据的传输流量, 因而可以节约大量的网络资源。
进一步地, 本发明实施例的移动多媒体广播业务系统中, 所述源平台 10为广电平台, 目标平台 20为移动业务平台。
本发明实施例的数据信息的传输装置, 参见图 11 , 其包括数据緩冲器 52和数据存储器 51。 该数据緩冲器 52和数据存储器 51为本发明实施例的 移动多媒体广播业务系统中涉及的数据緩冲器 30和数据存储器 40,在此不 再赘述。
