下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行 清楚、 完整地描述, 显然, 所描述的实施例是本发明的一部分实施例, 而不 是全部实施例。 基于本发明中的实施例, 本领域普通技术人员在没有做出创 造性劳动的前提下所获得的所有其他实施例, 都应属于本发明保护的范围。
本发明的技术方案, 可以应用于各种通信系统, 例如: 全球移动通信系 统(GSM, Global System for Mobile Communications ), 码分多址(CDMA, Code Division Multiple Access ) 系统, 宽带码分多址(WCDMA, Wideband Code Division Multiple Access Wireless ), 通用分组无线月良务技术( GPRS , General Packet Radio Service ), 长期演进 ( LTE, Long Term Evolution )等。
用户设备( UE, User Equipment )也可称之为移动终端( Mobile Terminal )、 移动台 (Mobile Station )等, 可以经无线接入网(例如, RAN, Radio Access Network ) 与一个或多个核心网进行通信。 UE 与无线接入网交换语音和 /或 数据。
基站,可以是 GSM或 CDMA中的基站( BTS, Base Transceiver Station ), 也可以是 WCDMA中的基站( Node B ),还可以是 LTE中的演进型基站( eNB 或 e-NodeB , evolutional Node B )„ 另夕卜, 一个基站可能支持 /管理一个或多 个小区 (cell ), UE需要和网络通信时, 它将选择一个小区发起网络接入。
在以下描述的本发明各个实施例中, 运营商网络引入 CDN功能单元为 各 ISP或各 ICP提供业务推送服务。 其中, CDN功能单元作为逻辑实体, 可以单独的 CDN服务器( Server )或以单板等形式融入无线通信网络网关中, 例如移动性管理实体( MME , Mobility Management Entity )或用户平面实体 ( UPE, User Plane Entity ) 中。
一般而言, 各 ISP/ICP根据签约实时地向 CDN功能单元推送各自网站 的热点信息以及推送优先等级。 CDN 功能单元根据其覆盖下的用户的点击 申请, 判断所在地区的申请量在前 5%的热点信息。 结合 ISP/ICP 申请的推 送优先等级, CDN 功能单元优选预推送业务内容, 执行广播预推送流程。 CDN业务推送协调传输方案的整体系统架构如图 1所示。
下面将结合图 2描述根据本发明一个实施例的聚合传输的方法。 其中, 包括如下步骤:
521 , CDN功能单元确定向 UE发送的热点信息, 其中所述热点信息由 ISP提供和 /或 ICP提供。
其中, ISP和 /或 ICP提供的热点信息可以包括在动态签约内容中, 且所 述动态签约内容还可以包括推送优先等级。
522, 然后, CDN功能单元向 UE发送调度信息, 其中所述调度信息用 于指示向所述 UE发送所述热点信息。
此外, 调度信息还可以包括热点信息的广播时刻。
523, 通过广播网络, CDN功能单元向所述 UE发送上述调度消息所指 示的热点信息以及与该热点信息对应的业务索引,其中所述热点信息对应的
URL与所述业务索引的映射关系包括在第一映射关系中。
例如, 通过广播网络, CDN 功能单元可以根据所述推送优先等级向所 述 UE发送上述调度消息所指示的热点信息以及与该热点信息对应的业务索 引。
因此, 本发明实施例在点播传输模式的基础上, 利用广播传输模式对高 相关性业务进行传输, 能够提高整网资源的利用率。 这里, 点播传输模式就 是通常的上网沖浪的点击模式, 它与 CMMB的广播传输模式相对。
由于通过广播传输模式传输的热点信息存在丟包的情况, 因此可以考虑 在通过广播网络向 UE发送调度消息所指示的所述热点信息的同时, CDN功 能单元通过通信网络(例如 LTE网络) 与 UE还建立重传链接, 例如 CDN 功能单元接收 UE发送的预推送融合传输请求, 再向 UE发送预推送融合传 输响应。 再例如, 通过广播传输模式传输热点信息的同时, CDN 功能单元 收到误块上报触发重传; 于是在热点信息的广播完成后, UE根据规则上报 接收状态, 用户点播热点信息时, CND 功能单元根据状态信息触发重传。 也就是说, 热点信息广播完成后的用户点播请求可以触发重传链接。 这样, CDN功能单元与 UE之间就可以通过重传链接,将 UE未收到的热点信息或 者其中的丟包进行重传。
具体而言, 当 UE通过广播网络接收到 CDN功能单元推送的热点信息 之后, 发现存在丟包的情况, 就会向 CDN功能单元发送预推送广播误块的 请求。 也就是说, CDN功能单元接收 UE发送的预推送广播误块的请求。 然 后, CDN功能单元会向 UE发送预推送广播误块。 可选的, 在 CDN功能单 元接收 UE发送的预推送广播误块的请求之后, CDN功能单元还会根据 UE 的 IMSI、 预推送广播误块的信息以及热点信息对应的 URL与业务索引更新 第一映射关系。 也就是说, CDN功能单元建立了 IMSI、 预推送广播误块与 对应的 URL (推送业务) 的关联, 这样的关联通过业务索引进行标识。
通常, URL与热点信息的关联主要是由 URL链接本身以及与 URL对应 的 ISP/ICP的签约来决定的。
当用户点击预查看的热点信息的 URL时, UE向 CDN功能单元发送业 务请求。 CDN功能单元接收到 UE发送的业务请求, 其中所述业务请求与热 点信息的 URL相对应, 然后根据该 UE的 IMSI和所述第一映射关系, 确定 所述业务请求对应的热点信息是否已经发送至所述 UE。 若确定所述业务请 求对应的热点信息已经完全推送至所述 UE,则 CDN功能单元仅将与所述热 点信息对应的业务索引发送给所述 UE。 若确定所述业务请求对应的热点信 息完全未推送至所述 UE, 则 CDN功能单元通过通信网络,将所述业务请求 对应的热点信息发送给所述 UE; 或者, 当所述业务请求对应的热点信息已 被推送过, 但存在部分误块需要重传的情况下, CDN 功能单元可以通过通 信网络将预推送广播误块发送给所述 UE。
在 CDN功能单元将热点信息发送给 UE后, UE将接收到的热点信息进 行緩存。 但是, 如果緩存溢出了, 将导致部分已推送过的数据被删除, 因此 必须通知 CDN功能单元前期已推送过的热点信息的緩存状态有变, 需要更 新第一映射关系。 此时, UE可能关闭热点信息广播的侦听等。
也就是, CDN功能单元通过通信网络接收所述 UE发送的緩存状态同步 消息, 所述緩存状态同步消息包括所述 UE已接收的热点信息的业务索引, 其中在緩存溢出的情况下, 所述緩存状态同步消息还可以携带剩余数据的緩 存状态。 然后, CDN 功能单元再通过通信网络, 根据所述用户设备已接收 的热点信息的业务索引, 更新所述第一映射关系。
因此, 本发明实施例在点播传输模式的基础上, 利用广播传输模式对高 相关性业务进行传输, 能够提高整网资源的利用率。 并且, 在广播传输模式 的同时通过点播传输模式来进行误块重传, 以保证热点信息推送的正确率。
在上述本发明实施例中, 由于在业务推送的同时也建立点播传输模式, 如果用户对已推送的内容不感兴趣, 也不会发出业务请求, 这样建立的点播 传输模式就浪费了无线频谱资源。 因此, CDN功能单元与 UE之间可并不先 建立重传链接, 而是在 UE发出业务请求时, 如果发现热点信息没有发送到 UE, 再与 UE之间建立重传链接。
也就是, CDN功能单元通过通信网络, 接收所述 UE发送的业务请求, 所述业务请求包括被请求的业务的 URL, 并根据所述被请求的业务的 URL, 确定与所述被请求的业务的 URL对应的被请求的业务是否为热点信息, 当 确定所述被请求的业务为热点信息时,根据所述用户设备的国际移动用户识 别码 IMSI和所述第一映射关系, 确定所述被请求的业务是否已经发送给所 述用户设备, 即 CDN判断是否执行过推送的热点信息。 如果 UE申请的是 热点信息, 则 CDN功能单元确定所述被请求的业务已经发送至所述用户设 备, 直接将业务索引发送给 UE, UE在收到业务索引后, 根据本地的热点信 息緩存状态获取对应的业务; 若 UE处完全未緩存数据, 则 UE再次请求完 整的业务传输; 若 UE处部分緩存热点信息, 则 UE申请误块的重传。 也就 是, 当 CDN功能单元确定所述被请求的业务未发送至所述用户设备, 通过 所述通信网络将所述业务请求对应的热点信息发送给所述用户设备。 如果 UE申请的不是热点信息, CDN功能单元将执行普通业务的传输过程, 反馈 对应的消息内容给 UE。
于是, UE接收到业务索引后, 对相应的热点信息预推送接收状态进行 判断: 若未接收到 CDN功能单元推送的热点信息, 则需要重新请求业务; 若接收到 CDN功能单元推送的部分热点信息,则请求 CDN功能单元传送误 块; 若接收到完整的热点信息, 则可以直接调用本地緩存数据执行的播放过 程。
也就是说,在所述 CDN功能单元将对应的所述业务索引发送给所述 UE 之后, 如果 UE发现该业务索引对应的热点信息存在误块, 则会向 CDN功 能单元发送预推送广播误块的请求。 当 CDN功能单元接收所述 UE的发送 预推送广播误块的请求之后,再向所述 UE发送所述预推送广播误块。这里, 所述预推送广播误块包括未通过所述广播网络发送到所述用户设备的热点 信息和未能保存在所述用户设备中的通过所述广播网络传送的热点信息中 的至少一种。
或者, CDN功能单元还会接收所述 UE发送的推送业务传送状态同步消 息, 并根据所述推送业务传送状态同步消息, 更新所述第一映射关系。 当用 户点击预查看的热点信息的 URL时, UE向 CDN功能单元发送业务请求。 CDN功能单元接收到 UE发送的业务请求,其中所述业务请求与热点信息的 URL相对应, 然后 居该 UE的 IMSI和所述第一映射关系, 确定所述业务 请求对应的热点信息是否已经发送至所述 UE。 若确定所述业务请求对应的 热点信息已经完全推送至所述 UE,则 CDN功能单元仅将与所述热点信息对 应的业务索引发送给所述 UE。 若确定所述业务请求对应的热点信息完全未 推送至所述 UE, 则 CDN功能单元通过通信网络,将所述业务请求对应的热 点信息发送给所述 UE; 或者, 当所述业务请求对应的热点信息已被推送过, 但存在部分误块需要重传的情况下, CDN 功能单元可以通过通信网络将预 推送广播误块发送给所述 UE。 或者, CDN功能单元会在接收所述 UE发送 的推送业务传送状态同步消息之后, 直接向 UE发送业务索引或误块。
同样地, 本发明实施例在点播传输模式的基础上, 利用广播传输模式对 高相关性业务进行传输, 能够提高整网资源的利用率。
下面结合图 3详细描述 UE侧的聚合传输的方法, 包括如下步骤。 由于 UE侧的聚合传输的方法与网络侧的聚合传输的方法相对应, 因此重复的内 容将被省略。
531 , UE从 CDN功能单元接收调度信息, 其中所述调度信息指示将要 接收的 ISP提供和 /或 ICP提供的热点信息。
其中, 所述调度信息还可以包括热点信息的广播时刻。
532, UE通过广播网络,接收所述调度信息所指示的所述热点信息以及 与所述热点信息对应的业务索引。
533, UE保存所述热点信息, 并根据所述热点信息与所述业务索引的映 射关系建立第二映射关系。
因此, 本发明实施例在点播传输模式的基础上, 利用广播传输模式对高 相关性业务进行传输, 能够提高整网资源的利用率。
在 UE通过中国移动多媒体广播 ( CMMB , China Mobile Multimedia
Broadcasting ) 网给或多媒体广播组播业务(MBMS , Multimedia Broadcast Multicast Service), 组播广播单频网 (MBSFN, Multicast Broadcast Single Frequency Network )等无线网络广播机制接收所述调度信息所指示的所述热 点信息的同时, UE可以通过通信网络(例如 LTE网络)与所述 CDN功能 单元建立重传链接。例如, UE向所述 CDN功能单元发送预推送融合传输请 求, 再从所述 CDN功能单元接收预推送融合传输响应。
在 UE与所述 CDN功能单元建立重传链接之后, UE还可以向所述 CDN 功能单元发送预推送广播误块的请求; 再接收所述 CDN功能单元发送的所 述预推送广播误块, 其中所述预推送广播误块包括未通过所述广播网络发送 到所述用户设备的热点信息和未能保存在所述用户设备中的通过所述广播 网络传送的热点信息中的至少一种。
在 UE需要获取热点信息时, UE可以通过通信网络向所述 CDN功能单 元发送业务请求, 所述业务请求与热点信息的 URL相对应。 之后, UE通过 通信网络, 从所述 CDN功能单元接收业务索引或者与所述业务请求对应的 热点信息, 所述业务索引与所述业务请求对应的热点信息关联。 UE通过通 信网络执行的单播业务接收流程如下:
若所述业务请求对应的热点信息已经完全推送至所述 UE, 则 UE从所 述 CDN功能单元中接收与所述热点信息对应的业务索引。 若所述业务请求 对应的热点信息完全未推送至所述 UE,则 UE从所述 CDN功能单元中接收 完整的热点信息; 或者, 当所述业务请求对应的热点信息已被推送过, 但存 在部分误块需要重传的情况下, UE通过通信网络从所述 CDN功能单元中接 收预推送广播的误块。
UE将接收到的热点信息进行緩存。 但是, 如果緩存溢出了, 将导致部 分已推送过的数据被删除, 因此 UE根据热点信息的緩存状态, 更新第二映 射关系, 并通知 CDN功能单元前期已推送过的热点信息緩存状态有变。
具体而言, UE通过通信网络, 向所述 CDN功能单元发送緩存状态同步 消息, 所述緩存状态同步消息包括已接收的热点信息的业务索引。 并且, UE 通过通信网络, 从所述 CDN功能单元接收根据緩存状态同步消息确定的需 要重传的热点信息;根据接收到的重传的热点信息,更新所述第二映射关系。
为了节省了宝贵的无线频谱资源, CDN功能单元与 UE之间可并不先建 立重传链接, 而是在 UE发出业务请求时, 如果发现热点信息没有发送到 UE, 再与 UE之间建立重传链接。 也就是, 预推送阶段 UE仅仅执行预推送 广播的接收, 不执行同步重传操作。 当用户发起业务请求时, UE通过通信 网络向 CDN功能单元发送对应的业务请求, 所述业务请求包括被请求的业 务的统一资源定位符 URL, 用于所述 CDN功能单元根据所述 URL判断 UE 所请求的业务是否是热点信息。 若该业务未执行过预推送, UE从所述 CDN 功能单元中接收完整的热点信息。 若该业务信息执行过预推送, UE从所述 CDN功能单元中接收对应的业务索引。 即, UE通过通信网络,从所述 CDN 功能单元接收所述被请求的业务的业务索引, 或者从所述 CDN功能单元接 收所述被请求的业务。
UE在收到业务索引后, 根据本地的热点信息緩存状态进一步申请传输 对应的业务; 若 UE处完全未緩存数据, 则 UE再次请求完整的业务传输; 若 UE处部分緩存热点信息, 则 UE申请误块的重传。 如果 UE申请的不是 热点信息, CDN 功能单元将执行普通业务的传输过程, 反馈对应的消息内 容给 UE。
于是, UE接收到业务索引后, 对相应的热点信息预推送接收状态进行 判断: 若未接收到 CDN功能单元推送的热点信息, 则需要重新请求业务; 若接收到 CDN功能单元推送的部分热点信息,则请求 CDN功能单元传送误 块; 若接收到完整的热点信息, 则可以直接调用本地緩存数据执行的播放过 程。
也就是说,在所述 CDN功能单元将对应的所述业务索引发送给所述 UE 之后, 如果 UE发现该业务索引对应的热点信息存在误块, 则会向 CDN功 能单元发送预推送广播误块的请求。 当 CDN功能单元接收所述 UE的发送 预推送广播误块的请求之后, 再向所述 UE发送所述预推送广播误块。
可选地, 预推送过程完成后 UE根据当前的热点信息緩存状态更新第二 映射关系,并向所述 CDN功能单元发送推送业务传送状态同步消息,由 CDN 功能单元根据所述推送业务传送状态同步消息, 更新所述第一映射关系。 当 用户点击预查看的热点信息的 URL时, UE向 CDN功能单元发送业务请求, 其中所述业务请求与热点信息的 URL相对应。 之后, UE通过通信网络执行 单播业务接收流程:
若所述业务请求对应的热点信息已经完全推送至所述 UE, 则 UE从所 述 CDN功能单元中接收与所述热点信息对应的业务索引。 若所述业务请求 对应的热点信息完全未推送至所述 UE,则 UE从所述 CDN功能单元中接收 完整的热点信息; 或者, 当所述业务请求对应的热点信息已被推送过, 但存 在部分误块需要重传的情况下, UE通过通信网络从所述 CDN功能单元中接 收预推送广播的误块。
因此, 本发明实施例在点播传输模式的基础上, 利用广播传输模式对高 相关性业务进行传输, 能够提高整网资源的利用率。
下面结合具体实施例, 详细描述根据本发明实施例的聚合传输的方法。 其中, 广播网络可以采用 CMMB模式; 另夕卜, 还可以采用 MBMS、 MBSFN 等多种无线网络广播机制。 应理解, 广播网络还可以采用其他模式。 以下以 通信网络为 LTE网络进行描述。
在第一实施例中, ISP/ICP通过因特网向 CDN功能单元推送动态签约内 容, 然后 CDN功能单元再分别通过 LTE网络与广播网络下发预推送业务的 调度信息至 UE,例如 CMMB-LTE双模终端。 CMMB广电网络可以 ^据 CDN 功能单元决策的调度信息, 向其覆盖下的 UE推送前 5%的热点信息或进行 直播业务的推送。 UE根据 CDN功能单元发送的调度信息,执行预推送业务 的接收与緩存, 同时建立对应的热点信息数据库。 也就是说, UE可以接收 到 CDN功能单元发送的调度信息, 该调度信息指示将向所述 UE发送的所 述 ISP/ICP提供的热点信息, 然后 CDN功能单元通过广播网络, 向所述 UE 发送所述调度消息所指示的所述热点信息以及与所述热点信息对应的业务 索引, 其中接收到的热点信息及其相对应的业务索引形成第二映射关系。 同 时, 在 CDN功能单元侧, 预发送的热点信息及其对应的业务索引形成第一 映射关系。
当用户点击前 5%的热点信息的 URL时, UE可以根据热点信息的上下 文直接调用緩存中的内容进行播放, 从而有效地保证了用户的观看体验。 由 此可见, 由于采用广播传输模式来发送热点信息, 因此可以提供整网资源的 利用率。
但是, 由于 CMMB广电网络采用的是广播传输模式进行数据传输, 因此 数据传输中一旦出现丟包,就无法执行重传操作。所以,在本具体实施例中, 进一步利用 LTE网络反馈 UE的接收状态, 这样 CDN功能单元就可以根据 UE 反馈的丟包情况, 来及时启动相应的重传机制。 重传机制可以是预推送过程 并发重传、 循环广播结束启动重传、 或者用户点击 URL触发对应业务重传。
在第二具体实施例中, 描述了预推送过程并发重传的过程。 由于广播覆盖性能较差, 为了保证预推送业务传输的可靠性, UE在接 收预推送业务广播的同时, 通过 LTE网络建立与 CDN功能单元之间的重传链 接。在并发重传过程中,预推送业务通过 LTE和 CMMB网络并发传输, CMMB 网络通过广播方式执行业务的初传, LTE网络则针对初传误块执行重传。
具体而言, 在并发传输业务建立过程中, LTE网络侧根据业务重传的服 务质量(QoS, Quality of Service )要求建立传输承载, 用以传输 CMMB广播 信道的误块。 在并发传输业务建立过程中, CDN功能单元向分组数据网 ( PDN, Packet Data Network ) 网关(GW, Gateway )查询当前 CMMB-LTE 双模终端的 IMSI, 用以建立用户设备与推送业务间的映射关系, 例如第一映 射关系。 图 4给出了 LTE协调传输业务的建立过程。
在第 1步中, CMMB业务调度计时器(Timer )到期, 终端启动 CMMB预 推送业务的接收。
在第 2步中, UE发起 PDP激活等用户面承载建立流程。
在第 3步中, UE向 CDN功能单元发送预推送业务融合传输请求消息, 请 求建立与 CDN功能单元之间的数据重传链接。
在第 4步中, CDN功能单元向 UE反馈预推送融合响应消息, 确认重传链 接建立。 此后 UE通过该重传链接向 CDN功能单元请求重传 CMMB预推送广 播的误块。
在第 5步中, CDN功能单元根据 UE的 IP地址向 GW请求当前 UE的 IMSI信 息。 此后, CDN功能单元可根据 UE的 IMSI、 推送业务误块信息、 当前推送 业务的签约 URL为每一 UE生成预推送状态数据库。
在第 6步中, UE根据第 3步与第 4步中协商的推送业务重传的应用层需求 信息, 生成数据重传 QoS要求, 并发起分组数据协议(PDP, Packet Data Protocol ) 更改流程。
在并发传输过程中, 预推送业务的初次传输由 CMMB广播网络完成。 同 时, CDN功能单元侧根据用户建立的 LTE协调传输信道数目, 为每一个 UE 建立一个应用层重传窗。 当 UE接收到的热点信息中存在误包时, 则由 LTE信 道执行数据重传。
当 CDN功能单元的预推送应用接收到预推送数据后,通常采用传输控制 协议( TCP, Transmission Control Protocol )层的数据帧分割原则对业务数据 进行分段, 例如业务数据包不够 1500字节 (byte )则不进行切割, 业务数据 包超出数据块按 1500byte的固定包大小切割应用层数据, 并将分段的业务数 据包进行级联。完成上述分段 /级联的数据块经过加预推送数据帧头等帧封装 操作后, 同时向发送緩存以及 UE各自的协同发送緩存传输, 并被緩存在 UE 中。发送緩存中的数据通过 CMMB广播系统向用户进行广播, 协同发送緩存 中的数据则留待收到来自各 UE的接收緩存中的接收反馈信息后再进行差异 化重传。 重传过程中, UE连续接收的数据包将移出预推送业务发送窗, 误 块则下发至 TCP层, 由 TCP层经过确认传输模式执行可靠传输。 CDN功能单 元侧应用层协调传输功能结构如图 5所示。
预推送业务的初传数据通过 CMMB广播系统发送至 UE的接收緩存。 对 于连续收到的数据包, 接收緩存直接递交至上层执行去预推送数据帧头、 业 务数据重组等操作。 对于未正确接收的包, UE生成确认帧发送至协同发送 緩存。 由 UE各自的协同发送緩存通过 LTE网络向 CDN功能单元上报。 CDN 功能单元的应用层将对应的重传包发送至各自 UE的 TCP层, 由 TCP层保证重 传的可靠性。 UE侧应用层协调传输功能结构如图 6所示。
在业务预推送过程中, CDN功能单元为每一个预推送业务分配一个业务 索引 (service index ), 并在本地保存 UE的 IMSI、 业务以及业务索引三者间的 映射关系, 例如第一映射关系。 对于未完成业务推送的 UE, CDN功能单元 还可进一步为 UE实时记录对应业务的误块信息。 下表 1给出了一个具体的预 推送业务索引表的示例。
表 1 预推送业务索引表
Figure imgf000021_0001
CDN功能单元在本地保存预推送的业务索引的同时,可在推送业务的过 程中, 也会将其为当前推送业务分配的业务索引发送至 UE侧保存。 UE可根 据接收到的业务索引建立起对应业务的索引数据库, 例如第二映射关系。 通 过预推送状态的同步机制, 使得 UE与 CDN功能单元两者可有效感知当前推 送业务的传送完成状态。 当 UE后续发起业务请求时, CDN功能单元可仅向 UE反馈业务索引的信息, 由 UE根据本地保存的预推送业务的业务索引, 直 接调用所緩存的业务内容。
由于 UE的緩存有限, 当预推送功能预留緩存溢出时, UE会删除部分预 緩存内容, 导致服务器与 UE间的预推送状态失步。 在发生緩存内容的变更 后, UE需上报緩存状态, 以维护预推送业务状态的同步。 UE的緩存管理流 程参见图 7。
第 1步中, UE发起 PDP激活等用户面承载建立流程。
第 2步中, UE向 CDN功能单元发送緩存状态同步消息, 指示 CDN功能单 元当前 UE已接收的预推送业务的緩存现状。
第 3步中, CDN功能单元根据 UE的网络协议(IP, Internet Protocol )地 址向 GW请求当前 UE的 IMSI。 此后, CDN功能单元可根据 UE的 IMSI以及 UE 上报的緩存状态调整当前 UE的预推送状态数据库, 使得 UE与 CDN功能单元 两侧的业务预推送状态保持一致。
下面结合图 8具体描述本发明实施例的聚合传输方法如何提供网络的传 输效率。
用户点击已完成推送的热点信息的 URL时, UE向 CDN功能单元请求对 应的业务内容。 CDN功能单元在判决是否执行内容推送前, 首先查询 PDN网 关确认当前 UE的 IMSI。 若未针对该 UE执行业务预推送, 则 CDN功能单元直 接向 UE返回热点信息。 整个数据传输过程维持原有的超文本传输协议 ( HTTP , Hypertext Transfer Protocol )交互流程不变。 若已完成业务预推送, CDN功能单元直接返回预推送业务的索引值。 由 UE根据热点信息的上下文 直接调用緩存内容进行播放, 以保证用户的观看体验。
进一步地, 若预推送过程中存在部分热点信息中的内容未完成传输, 可 在 HTTP响应消息中一并下发未传输的热点信息的内容。 此种处理方式需要 浏览器等支持类似网络蚂蚁的断点续传能力。
采用预推送过程并发重传机制, UE完成按现有的 HTTP交互流程实现业 务流程, 有效地保证了业务传输的环回时间。 具体业务流程参见图 8。 第 1步, 用户点击 URL链接, 发起相关移动互联业务的业务请求。
第 2步, UE发起 PDP激活等用户面承载建立流程。
第 3步, 由于 URL链接所对应的移动互联已推送至 CDN功能单元侧, UE 直接向 CDN功能单元发起超文本传输协议请求 (HTTP GET , Hypertext Transfer Protocol GET ) 消息业务请求。
第 4步, CDN功能单元根据 UE的 IP地址向网关请求当前 UE的 IMSI。根据 查询所得的 IMSI, 查询用户当前申请的业务是否已向当前 UE执行过预推送, 并确定相应的响应消息。
第 5步, CDN功能单元向 UE反馈超文本传输协议响应 ( HTTP RESPONSE ) 消息。
如果 CDN功能单元已为 UE执行过当前业务的预推送, 则 HTTP RESPONSE消息中仅携带有当前业务的预推送的业务索引。若根据预推送状 态数据库, 当前业务剩余部分数据未推送成功, 则 HTTP RESPONSE消息中 可进一步携带待重传数据。 极端情况下, 若 UE在预推送过程中处于盲区, 完全未接收预推送数据, 则 HTTP RESPONSE消息将完全遵照现有的 HTTP 流程, 直接返回相应的热点信息。
由此可见, 本发明实施例在点播传输模式的基础上, 利用广播传输模式 对高相关性业务进行传输, 能够提高整网资源的利用率。
在第二具体实施例中, 业务预推送过程通过并发的 LTE传输执行广播误 包的重传, 以保证预推送内容的正确率。 而根据当前数据统计, 仅 70%的用 户关注前 5%的热点信息。 对于不关注所推送内容的用户, 由于用户后续不 会通过无线网络申请对应业务, 第二具体实施例中的 LTE并发传输为无效传 输, 导致了宝贵无线频谱资源的浪费。
在第三具体实施例中, 预推送过程采用尽力而为 (BE, best effort )方 式传输, UE在预推送过程中仅执行广播接收。 对于预推送过程的误包, 仅 在后续用户点击 URL链接申请对应的业务时通过 LTE网络实现误包重传。
例如, 在 CMMB调度计时器到期后, CDN功能单元通过 CMMB发射机 执行预推送信息的广播。 CMMB-LTE双模终端作为一个 CMMB终端完成预推 送业务的接收。
在业务预推送过程中, CDN功能单元为每一个预推送业务分配一个业务 索引, 并在本地保存业务与业务索引间的映射关系。 下表 2给出了具体的预 推送业务索引表的示例。
表 2预推送业务索引表
Figure imgf000024_0001
在业务预推送过程中 , CDN功能单元将其为当前推送业务分配的业务索 引下发至 UE侧保存。 UE可根据接收到的业务索引建立起对应业务的索引库, 如第二映射关系。 由于 CDN功能单元没有 UE上下文的相关信息, 无法记录 UE的接收状态。此时 CDN功能单元与 UE两侧仅执行 "业务是否执行过推送" 这一状态的同步。 当 UE后续发起业务请求时, CDN功能单元可仅向 UE反馈 业务索引。 UE若完成了预推送业务的业务索引的本地保存, 则可直接调用 所緩存的业务内容。 若 UE因 CMMB覆盖等原因未完成预推送业务, 需发起 进一步的业务请求。
图 9给出了业务发送过程的流程图。 其中, 用户点击预推送的热点信息 的 URL时, UE向 CDN功能单元请求对应的业务内容, 即发送业务请求。 CDN 功能单元根据其内部维护的预推送业务数据库, 判决用户申请的业务 是否完成业务预推送。 若未执行业务预推送, 则 CDN功能单元直接向 UE 返回热点信息。 整个数据传输过程维持原有的 HTTP交互流程不变。 若已完 成业务预推送, 则 CDN功能单元直接返回预推送业务的业务索引。 由 UE 根据热点信息的上下文直接调用緩存内容进行播放, 以保证用户的观看体 验。
进一步地, 若预推送过程中存在部分热点信息的内容未完成传输, UE 在业务传输过程中向 CDN功能单元上 预推送业务的误块信息,由 CDN功 能单元通过 LTE网络执行重传。 极端情况下, UE若未接收过当前业务的预 推送, UE需再次发起 HTTP业务请求。 具体业务流程参见图 9。 用户点击 URL链接, 发起相关移动互联业务的请求。
第 1步, UE发起 PDP激活等用户面承载建立流程。
第 2步, 由于 URL链接所对应的移动互联已推送至 CDN功能单元侧, UE 直接向 CDN功能单元发起 HTTP GET业务请求。
第 3步, CDN功能单元向 UE反馈 HTTP RESPONSE消息。
CDN功能单元已为 UE执行过当前业务的预推送,因此 HTTP RESPONSE 消息中仅携带有当前业务的预推送索引的业务索引。
第 4步, UE接收到 HTTP RESPONSE消息后, 读取其中的业务索引, 并 查询其内保存的业务预推送索引数据库, 直接调用緩存内容进行播放, 以保 证用户的观看体验。
第 5步, 若预推送业务存在部分误块未完成传输, UE向 CDN功能单元发 送预推送广播误块的请求, 请求 CDN功能单元对剩余数据进行重传。
第 6步, CDN功能单元向 UE反馈重传确认消息, 同时启动预推送广播误 块的断点续传功能, 向 UE发送预推送广播误块。 极端情况下, 若 UE完成没 有接收过业务预推送(推送时刻处于盲区), UE将再次发起 HTTP数传流程, 服务器将直接返回对应的热点信息。
由此可见, 本发明实施例在点播传输模式的基础上, 利用广播传输模式 对高相关性业务进行传输, 能够提高整网资源的利用率。
在第三具体实施例中, 由于 CDN功能单元无法获取 UE的緩存状态, 使得 UE在业务传输过程中必须重复执行 HTTP GET过程, 因而点播业务的 传输环回时间严重影响了用户的实用体验。 因此, 本发明的第四具体实施例 对第三具体实施例进行了优化, 引入了 UE与 CDN功能单元之间的緩存状 态同步流程。
与第三具体实施例类似, 第四具体实施例的预推送过程同样采用 BE方 式传输, CMMB-LTE双模终端在预推送过程中仅执行广播接收。 为了保证 CDN功能单元与 UE两侧预推送业务接收状态的同步,在每次预推送过程结 束后, UE主动发起业务传送同步流程, 即向 CDN功能单元上报 UE的预推 送业务的接收状态, 如误块信息。 CDN 功能单元通过查询 PDN 网关, 将 UE上报的业务接收状态与 UE标识进行关联。 图 10给出了具体的推送业务 传送状态同步流程。 第 1步, UE发起 PDP激活等用户面承载建立流程。
第 2步, UE向 CDN功能单元发送推送业务传送状态同步消息, 指示 CDN功能单元当前预推送业务的緩存现状, 如误块信息等。
第 3步, CDN功能单元根据 UE的 IP地址向网关请求当前 UE的 IMSI。 此后, CDN功能单元可根据 UE的 IMSI和 UE上报的预推送业务緩存状态 调整当前 UE的预推送状态数据库,使得 UE与 CDN功能单元两侧的业务预 推送状态保持一致。
可以理解, 在同步流程完成后, CDN功能单元侧预推送业务索引可参见 第二具体实施例。 由于本具体实施例要求 UE与 CDN功能单元两侧的预推 送业务的緩存状态同步, 当发生 UE的緩存溢出等异常事件时, UE需上报 其緩存状态。 具体上报流程同第二具体实施例。
预推送错误包的实际重传由用户点击 URL链接申请对应的业务时通过 LTE网络重传错误包完成。 由于 CDN功能单元获取了 UE预推送业务的接 收状态, 整个业务传输过程可采用并发传输方案的聚合传输模式, 具体的业 务传输流程参见第二具体实施例。
由此可见, 本发明实施例在点播传输模式的基础上, 利用广播传输模式 对高相关性业务进行传输, 能够提高整网资源的利用率。

由此可见, 本发明实施例在点播传输模式的基础上, 利用广播传输模式 对高相关性业务进行传输, 能够提高整网资源的利用率。
图 33示出了根据本发明实施例的聚合传输的系统的结构。 聚合传输的 系统 330可以包括如图 11至图 20所示的聚合传输的装置 331 (例如, CDN 服务器), 以及如图 21至图 30所示的聚合传输的装置 332 (例如 UE )。 其 中, 聚合传输的装置 331与聚合传输的装置 332之间通过广播网络以及通信 网络连接。
首先,聚合传输的装置 331确定向聚合传输的装置 332发送的热点信息, 所述热点信息通常由 ISP提供和 /或 ICP提供。
接着, 聚合传输的装置 331通过通信网络向聚合传输的装置 332发送调 度信息。 当聚合传输的装置 332接收到该调度信息, 则获知聚合传输的装置 331将向其发送热点信息。
最后, 聚合传输的装置 331通过广播网络向聚合传输的装置 332发送热 点信息及其对应的业务索引。 聚合传输的装置 332则将接收到的热点信息保 存在本地, 并在本地依据接收到的热点信息与对应的业务索引建立第二映射 关系。 同样的, 聚合传输的装置 331也可以依据发送的热点信息及其对应的 业务索引、 URL以及接收到热点信息的聚合传输的装置 332的 IMSI等建立 第一映射关系。 可以理解, 聚合传输的装置 332的第二映射关系与聚合传输 的装置 331的第一映射关系是相互关联的。 即聚合传输的装置 331每发送出 一条热点信息, 在第一映射关系中创设一个映射条目; 相应地, 聚合传输的 装置 332接收待该条热点信息, 则在第二映射关系中创设一个相应的映射条 目。 于是, 当用户在聚合传输的装置 332触发业务请求, 该业务请求包括了 被请求的业务的 URL, 若该 URL对应热点信息且聚合传输的装置 331通过 第一映射关系确定该热点信息之前已经通过广播网络发送给聚合传输的装 置 332, 则聚合传输的装置 331只需要通过通信网络将对应的业务索引发送 给聚合传输的装置 332, 而无需再次传输热点信息。 这样, 聚合传输的装置 332可以依据聚合传输的装置 331提供的业务索引, 直接在本地获取到请求 的热点信息。 若用户在聚合传输的装置 332触发的业务请求中包括的 URL 不是热点信息, 或者 URL对应热点信息但聚合传输的装置 331还未通过广 播网络发送给聚合传输的装置 332, 则聚合传输的装置 331可以再通过广播 网络或通信网络将业务请求中包括的 URL对应的内容发送给聚合传输的装 置 332。
可以理解, 正常传输的情况下, 聚合传输的装置 332保存在本地的热点 信息与聚合传输的装置 331发送给其的热点信息是一致的。 但是, 通过广播 传输模式传输的热点信息会存在丟包的情况, 因此需要在聚合传输的装置 331与聚合传输的装置 332之间在通信网络中建立重传链接。 其中, 该重传 链接可以在聚合传输的装置 331通过广播网络向聚合传输的装置 332发送热 点信息以及业务索引的同时建立,也可以在聚合传输的装置 332发出业务请 求并发现热点信息没有被完整地发送时建立。
聚合传输的装置 331与聚合传输的装置 332之间的重传链接的建立可以 通过以下过程实现: 聚合传输的装置 332向聚合传输的装置 331发送预推送 融合传输请求消息, 当聚合传输的装置 331接收到预推送融合传输请求消息 之后, 再向聚合传输的装置 332发送预推送融合传输响应消息。 于是, 聚合 传输的装置 331与聚合传输的装置 332之间的重传链接建立。
在一种实施例中, 在重传链接建立之后, 聚合传输的装置 332通过通信 网络向聚合传输的装置 331发送预推送广播误块的请求,接着聚合传输的装 置 331通过通信网络向聚合传输的装置 332发送预推送广播误块。 当聚合传 输的装置 332接收到预推送广播误块, 可以获取完整的热点信息。 此时, 聚 合传输的装置 331和聚合传输的装置 332都需要分别更新第一映射关系和第 二映射关系。
在另一实施例中, 聚合传输的装置 332通过通信网络向聚合传输的装置 331发送业务请求, 该业务请求中包括请求的热点信息的 URL。 当聚合传输 的装置 332确定该 URL对应的热点信息没有被完整的接收时, 将与, 聚合 传输的装置 331建立重传链接。 然后, 聚合传输的装置 332通过通信网络向 聚合传输的装置 331发送预推送广播误块的请求, 接着聚合传输的装置 331 通过通信网络向聚合传输的装置 332发送预推送广播误块。 当聚合传输的装 置 332接收到预推送广播误块, 可以获取完整的热点信息。 此时, 聚合传输 的装置 331和聚合传输的装置 332都需要分别更新第一映射关系和第二映射 关系。
还有一种场景是, 聚合传输的装置 331向聚合传输的装置 332发送的热 点信息的大小超出了聚合传输的装置 332的本地存储容量, 因此将导致聚合 传输的装置 332緩存溢出。 可以理解, 此时聚合传输的装置 331的第一映射 关系与聚合传输的装置 332的第二映射关系将出现不一致性。 即聚合传输的 装置 331的第一映射关系中记录热点信息已发送给聚合传输的装置 332, 但 是聚合传输的装置 332却没有能够获取到。 为了保证聚合传输的顺利进行, 聚合传输的装置 332需要定期或在发送緩存溢出的情况下, 向聚合传输的装 置 331发送緩存状态同步消息, 即告知聚合传输的装置 331 自己实际能够获 取到的热点信息是哪些。 这样, 聚合传输的装置 331可以据此更新第一映射 关系, 保持第一映射关系与第二映射关系的一致性。
以上结合图 33对聚合传输的系统的工作流程进行了筒单说明, 具体的 聚合传输的装置 331和聚合传输的装置 332的工作流程可以参见图 2至图 32 中的具体描述, 在此不再赘述。
