Description

一种移动网络中分发数据的方法、装置和系统
本申请要求于2015年12月25日提交中国专利局、申请号为201510991384.2、发明名称为“一种移动网络中分发数据的方法、装置和系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术领域，尤其涉及一种移动网络中分发数据的方法、装置和系统。
背景技术
CDN(Content Delivery Network，内容分发网络)是通过在互联网的各处放置用于缓存内容提供服务器提供的数据的缓存服务器(也可称为CDN服务器或节点服务器)，从而构成在现有的互连网基础之上的一层智能虚拟网络。CDN能够在固网环境下，实现数据的快速传输；具体的：在固网环境中，终端设备可以从与其距离较近的CDN服务器中获取数据，而不需要从内容提供服务器获取数据，这样能够尽可能避开互联网上有可能影响数据传输速度和稳定性的瓶颈和环节，从而使数据传输的更快更稳定，进而减少访问延时和传输带宽开销。
在移动网络环境下，为了达到上述目的，可以将CDN服务器设置在互联网的“边缘”，一般地，可以将CDN服务器设置在核心网侧，更进一步地，可以将CDN服务器设置在基站侧。目前，最大程度上减少访问延时和传输带宽开销的方案是，将CDN服务器设置在基站侧；但是，这样，仍然需要消耗数据由基站发往终端设备的过程中所使用的空口资源，而空口资源是较为紧缺的资源，因此有必要提供一种节约空口资源的技术方案。
发明内容

第二方面，提供了一种第一节点，应用于移动网络中，第一节点包括：
接收单元，用于接收业务的标识信息所指示的数据；
缓存单元，用于缓存所述业务的标识信息所指示的数据；

下面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示例性描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。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前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，现有技术中所提供的CDN网络主要是为了实现固网中的数据分发，本发明实施例所提供的技术方案是为了实现移动网络中的数据分发。在本发明实施例中，如图8所示，缓存数据的设备(例如CCS和eNB)类似于背景技术中所述的CDN服务器。
下文中首先提供了移动网络中节点之间分发数据的网络架构，如图1或2所示；并提供了基于该网络架构下的节点分发数据的交互方法，如图3-6任意一个附图所示；接着，提供了本发明实施例所适用的移动网络架构，如图7或8所示，并提供了基于该移动网络架构的移动网络中分发数据的方法，其中涉及数据如何由内容提供服务器传输至基站，以及在该过程中所涉及的对该数据的处理过程等内容，如图9-11所示。最后，提供了与上述分发数据的节点方法相对应的装置实施例，以及系统实施例。
本申请中的“节点(包括第一节点和第二节点)”均可以是终端设备或基站。
基于上述提供的任一种通信系统，下面列举本发明实施例提供的移动网络中分发数据的方法所适用的网络架构，具体的：一种可选的网络架构可以包括N个终端设备，N2，N是整数，如图1所示，其中，图1中以N＝3为例进行说明。另一种可选的网络架构可以包括M个基站和N个终端设备，M1，N2，M和N均是整数，如图2所示，其中，图2中以N＝2，N＝3为例进行说明。
在图1所示的网络架构中，每个终端设备均可以分发自身所缓存的数据，也可以接收其他终端设备所分发的数据。在图2所示的网络架构中，每个基站可以分发自身所缓存的数据，也可以接收其他终端设备或基站所分发的数据；每个终端设备均可以分发自身所缓存的数据，也可以接收基站或其他终端设备所分发的数据。其中，基站可以通过传统的数据发送方式(例如广播或组播或单播等方式)在空口将所缓存的数据分发给其覆盖范围内的一个或多个节点。图2中以基站1将所缓存的数据分发给基站2、终端设备1、终端设备3为例，基站2将所缓存的数据分发给基站1、终端设备1、终端设备2为例进行说明。
本发明实施例提供的技术方案的基本原理是：当一个节点中缓 存有目标业务的标识信息所指示的数据时，其他节点可以从该节点中获取该数据；这样，终端设备可以从缓存有该数据的终端设备中获取该数据，从而不需要再从基站获取，从而减少了终端设备与基站之间的信息交互，节省了空口资源。
在下文中，将分发自身所缓存的数据的节点均称为“分发节点”，将接收所分发的数据的节点称为“接收节点”。分发节点和接收节点均可以是基站或终端设备。一个节点(包括终端设备或基站)可以在一个时刻作为分发节点，并在另一时刻作为接收节点；也可以同时作为分发节点和接收节点。一个节点具体作为分发节点还是接收节点取决于该节点是在分发数据还是在接收数据。
需要说明的是，下文中均以“节点”是终端设备，并且以节点分发目标业务为例进行说明，其中，目标业务可以是任意一种业务。本领域普通技术人员应当理解，下文中的任意一个终端设备均可以用基站替换。
下面以“分发节点为第一终端设备，接收节点为第二终端设备”为例对本发明实施例提供的移动网络中分发数据的方法进行示例性地说明。本领域普通技术人员应当理解，第一终端设备和第二终端设备均可以被基站替换。如图3所示，该方法包括以下步骤S101-S103：
S101：第二终端设备确定目标业务的标识信息。
“业务”具体可以是多媒体业务，例如视频、图片、广播、广告、信息等。终端设备获取到的业务的各项信息，例如业务的标识信息、业务的数据、业务的配置信息等，均来自网络侧设备；例如，业务的数据来自网络侧的内容提供服务器，业务的配置信息可以来自网络侧的核心网网关或基站等设备。但是，具体实现时，终端设备可以直接从其他终端设备或网络侧的基站中获取业务的各项信息，并且不同的信息可以从不同的终端设备或基站上获取，例如，终端 设备1可以从终端设备2中获取一业务的标识信息，并从终端设备3中获取该业务的配置信息，从终端设备4中获取该业务的部分数据，从基站中获取该业务的其他部分数据等。
“目标业务”是指第二终端设备待获取的一个业务，例如，一部微电影，一篇文章等。“目标业务的业务段”是指目标业务的部分数据；具体的：网络侧设备，例如核心网网关或基站等设备，按照一定的规则将目标业务的数据分为多个部分，并为每个部分分配标识，其中每个部分即为目标业务的一个业务段。例如，按照时间的先后顺序将一个微电影的数据均分为10个子集，又如，将一篇文章的数据分为5个章节，再如，将一个数据包分割为20个数据子包等。当然还可以利用其他任何一种方式将业务分为多个业务段。具体实现时，可以通过统一的方式对目标业务的标识信息(包括：目标业务的标识，以及目标业务的标识与业务段的标识的组合)进行编码，具体的：可以通过人可识别的层级命名方式，例如video.youku.id1283.seg89表示youku.com网站上视频编号为1283的第89个片断；或者可以通过按指定规则数字编码的方式，将上述标识信息进行编码，从而节省标识长度。
“目标业务的标识信息”可以是目标业务的标识，例如待获取的微电影对应的URL(Uniform Resource Locator，统一资源定位符)，待获取的文章对应的URL等；也可以是目标业务的标识和目标业务中待获取的业务段的标识的组合，例如，待获取的微电影对应的URL和该微电影的第3个子集的标识的组合，待获取的文章对应的URL和该文章的第2个章节的标识；当然还可以为其他任一能够唯一标记待获取的数据的信息。
需要说明的是，当业务的标识信息是业务的标识和该业务中的待获取的业务段的标识的组合时，可以将一个业务的部分业务段的数据缓存在一个分发节点中，将该业务的另一部分业务段的数据可 以缓存在其他分发节点中。这样，能够避免因将一个业务的所有数据均缓存在一个分发节点(尤其是指终端设备)中，从而导致的该分发节点的性能较差的问题。在该实现方式中，接收节点所获取到的业务的数据可能可以来自多个分发节点。
在步骤S101之前，该方法还可以包括：第二终端设备接收来自网络侧设备(例如核心网网关或基站等)的目标业务的配置信息；具体的：第二终端设备可以接收基站配置并发送的，或由核心网网关配置的目标业务的并经基站转发的配置信息；或者，第二终端设备可以接收由基站或核心网网关配置的，并经其他终端设备转发的目标业务的配置信息。其中，该配置信息包括目标业务中的各业务段的标识，用于指示第二终端设备确定目标业务的标识信息。
步骤S101可以在步骤S104之前的任一步骤中执行。
S102：第一终端设备接收并缓存目标业务的标识信息所指示的数据。
其中，目标业务的标识信息所指示的数据可以来自于基站或其他终端设备。具体的：第一终端设备可以直接接收基站或经其他终端设备转发的目标业务的标识信息所指示的数据，本发明实施例对此不进行限定。
在本发明实施例中，第一终端设备是缓存有目标业务的标识信息所指示的数据的一个终端设备。同一时刻，网络中缓存有目标业务的标识信息所指示的数据的终端设备的数量可能为0，也可能为1个或多个。
S103：第一终端设备分发目标业务的标识信息所指示的数据，以使其他终端设备从第一终端设备中获取目标业务的标识信息所指示的数据。
第一终端设备可以在缓存了目标业务的标识信息所指示的数据之后，按照广播或组播或其他方式分发目标业务的标识信息和目标 业务的标识信息所指示的数据，以使其他终端设备可以从第一终端设备中获取该数据。
S104：第二终端设备接收第一终端设备分发的目标业务的标识信息所指示的数据。
在步骤S104之前，该方法还可以包括：第二终端设备发现第一终端设备，并与第一终端设备之间建立连接；或者第一终端设备发现第二终端设备，并与第二终端设备之间建立连接。
以第二终端设备发现第一终端设备为例进行说明，第二终端设备可以通过扫描的方式发现周围的设备；其中，该设备可以是终端设备也可以是基站。当该设备是终端设备时，第二终端设备建立与该终端设备之间的连接，从而与该终端设备进行通信；当该设备是基站时，第二终端设备可以直接与基站进行通信。
需要说明的是，当第二终端设备在预定的时间段内未与缓存有目标业务的标识信息所指示的数据的终端设备建立连接时，可以认为第二终端设备没有发现分发该数据的节点，并且没有被分发节点发现；该情况下，第二终端设备可以直接向网络(例如基站)请求该数据。
本发明实施例提供的移动网络中分发数据的方法，第二终端设备确定目标业务的标识信息，并接收第一终端设备分发的目标业务的标识信息所指示的数据。这样，第二终端设备可以直接接收第一终端设备发送的数据，而不需要再向基站获取该数据，从而减少了终端设备与基站之间的信息交互，节省了空口资源。
需要说明的是，现有技术中，每个终端设备均需要从基站获取数据，并且，基站一旦获取到针对一个或多个终端设备的数据之后，就会立即发送给该一个或多个终端设备，而不会缓存该数据。在本发明实施例中，上述第一终端设备也可以替换为基站，该方案具体为：基站接收并缓存目标业务的标识信息所指示的数据；然后分发 目标业务的标识信息所指示的数据，以使其他节点(其他基站或终端设备)从该基站中获取目标业务的标识信息所指示的数据。其中，基站所接收的目标业务的标识信息所指示的数据可以来自核心网网关，具体过程可以参考下文中的所述的阶段3。
结合图3，在一种可选的实现方式中，如图4所示，在步骤S104之后，该方法还可以包括以下步骤S105：
S105：第二终端设备缓存目标业务的标识信息所指示的数据，并分发第二通知消息，其中，第二通知消息中包括目标业务的标识信息，用于通知接收到第二通知消息的终端设备：第二终端设备中缓存有目标业务的标识信息所指示的数据。
具体实现时，接收到第二通知消息的终端设备可以向第二终端设备请求目标业务的标识信息所指示的数据。在该可选的实现方式中，第二终端设备在向第一设备请求目标业务的标识信息所指示的数据的过程中，作为接收节点。另外，第二终端设备在获取到目标业务的标识信息所指示的数据之后，具有分发节点的分发功能，可以作为分发节点。
结合图3，在一种可选的实现方式中，如图5所示，在步骤S103之前，该方法还可以包括以下步骤S102a-S102c：
S102a、第一终端设备分发通知消息，其中，通知消息中包括目标业务的标识信息，用于通知接收到通知消息的节点：第一节点中缓存有目标业务的标识信息所指示的数据。
该实现方式中的“通知消息”与本申请中的“第一通知消息”的含义相同，二者可以互换使用。具体实现时，接收到通知消息的终端设备可以向第一终端设备发送业务数据请求消息，以请求目标业务的标识信息所指示的数据。
第一终端设备在缓存了任何一个业务的标识信息所指示的数据之后，均可以在空口的指定的配置(例如基站的无线承载配置等) 上，通过广播或组播或其他方式分发包含该业务的标识信息的通知消息，以使接收到该通知消息的终端设备(包括第二终端设备)可以向第一终端设备请求该数据。另外通知消息中还可以包括该数据的数据包状态信息、该数据的概略信息等；其中，该数据的概略信息可以包括但不限于以下信息中的一种或几种：该数据所占的存储空间的大小、该数据的大小占该业务的大小的百分比等，该数据的接收时间，接收源设备信息(如是从基站获取还是从其他缓存设备获取)，缓存的新鲜度(如接收后缓存的时间)等。需要说明的是，包含该数据的概略信息的通知消息能够使接收到该通知消息的终端设备更准确地获知第一终端设备是否缓存了待获取的数据。
当第一终端设备中缓存有不同的业务标识信息所指示的数据时，第一终端设备可以在一个通知消息中携带一个或多个业务标识信息。步骤S102a可以通过以下方式实现：第一终端设备分发第一通知消息，其中，第一通知消息包括第一终端设备中缓存的至少一种业务的标识信息；该至少一种业务的标识信息中包含目标业务的标识信息。
S102b、第二终端设备接收第一终端设备分发的通知消息。
第二终端设备可以通过扫描的方式发现周围的设备；其中，该设备可以是终端设备也可以是基站。当该设备是终端设备时，建立与该终端设备之间的连接，然后接收该终端设备发送的通知消息，以获知该终端设备中所缓存的业务的标识信息中是否包含目标业务的标识，从而确定该终端设备是否是分发节点(即分发目标业务的标识信息所指示的数据的设备)。另外，当该设备是基站时，第二终端设备可以直接向基站发送业务数据请求消息，以请求目标业务的标识信息所指示的数据。需要说明的是，基站中缓存有任何一个业务的标识信息所指示的数据。
需要说明的是，数据分发的过程属于按需(on-demand)类型或 者伺机(opportunistic)类型，因此分发节点(具体是指终端设备)和接收节点之间不需要建立持久的连接，例如第二终端设备与第一终端设备之间不需要建立持久的连接，如需建立连接，接收数据结束后自动释放连接。
S102c、第二终端设备根据通知消息确定第一终端设备中缓存有目标业务的标识信息所指示的数据，然后向第一终端设备发送业务数据请求消息。其中，业务数据请求消息中包含目标业务的标识信息，用于指示第一终端设备向第二终端设备发送目标业务的标识信息所指示的数据。
若第二终端设备所发现的多个设备(包括终端设备和基站)中均缓存有目标业务的标识信息所指示的数据，即第二终端设备接收到多个设备发送的通知消息中均包含目标业务的标识信息，则第二终端设备可以向随机选择的一个设备或首次发现的一个设备发起业务数据请求消息，以请求目标业务的标识信息所指示的数据；还可以按照网络侧设备作指示的目标业务的配置信息中所包含的参与分发目标业务的数据的至少两个设备(包括终端设备和基站)的优先级顺序，向该多个设备中的优先级较高一个设备发起业务数据请求消息，以请求目标业务的标识信息所指示的数据。具体实现时，当第二终端设备在指定的时间内无法从优先级较高的设备中获取到该数据之后，可以向优先级次之的设备获取该数据。并且，为了节省基站的空口资源，可以将基站的优先级设置的较低，以使得第二终端设备优先向其他终端设备获取数据。本发明实施例对终端设备的优先级顺序的设置方式不进行限制，例如，可以根据是否网络侧设备监测到的终端设备的空闲状态进行确定，或根据终端设备的签约信息进行确定，或采用默认方式，如终端设备的优先级高于微站设备(例如小基站)的优先级，微站设备的优先级高于宏基站设备的优先级等。优先级信息可以由缓存有该优先级信息的设备在空口发 送。
其中，“参与分发目标业务的数据的设备”可以是网络侧设备预先设置好的终端设备。例如，网络侧设备可以在一个终端设备的签约信息中记录该终端设备是否作为某个或某些业务的数据的分发节点，然后对每个业务对应的多个分发节点设置优先级顺序；或者，网络侧设备监测并将指定时间内进入一基站的覆盖范围内的终端设备作为该指定时间内所推送的业务的发送设备，然后根据这些发送设备的性能等确定这些分发节点的优先级顺序。需要说明的是，当前时刻，参与分发目标业务的数据的设备中可以缓存有目标业务的标识信息所指示的数据，也可以是因未处在待分发的基站的覆盖范围内或自身的故障等原因而导致其还未缓存目标业务的标识信息所指示的数据。
在该可选的实现方式中，步骤S103可以实现为以下步骤S103'：
S103'、第一终端设备在接收到第二终端设备发送的数据业务请求消息之后，向第二终端设备发送目标业务的标识信息所指示的数据。
在图4所示的可选的实现方式中，第一终端设备首先分发业务的标识信息，然后在需要该业务的标识信息所指示的数据的第二终端设备的请求下才向第二终端设备发送该数据，而非直接分发该数据，这样能够避免向不需要该数据的终端设备发送该数据，从而造成的资源浪费的问题。
结合图3，在另一种可选的实现方式中，如图6所示，在步骤S101之后步骤S103之前，该方法还可以包括以下步骤S101a：
S101a、第二终端设备分发缓存请求消息，其中，缓存请求消息中包括目标业务的标识信息。
第二终端设备在空口通过广播或组播或其他方式分发缓存请求消息，以使接收到该缓存请求消息的设备(包括终端设备和基站) 在确定自身中缓存有目标业务的标识信息所指示的数据时，向第二终端设备发送目标业务的标识信息所指示的数据。其中，接收到该缓存请求消息的设备包括第一终端设备。
图6中以步骤S101a在步骤S102之前为例进行说明的，具体实现时，步骤S101a可以与步骤S102同时执行，或者在步骤S102之后执行。
该情况下，步骤S103可以包括以下步骤S103”：
S103”、第一终端设备在接收到第二终端设备分发的缓存请求消息之后，向第二终端设备分发目标业务的标识信息所指示的数据。
第二终端设备可以在确定目标业务的标识信息之后，即通过广播或组播或其他方式向外发送包含有目标业务的标识信息的缓存请求消息。
上文提供的数据分发的方法是建立在分发节点(例如终端设备或基站)已经缓存有目标业务的标识信息所指示的数据的基础之上的，或者是说建立在网络侧的基站已经分发了该数据的基础之上的。下面重点说明基站分发数据的过程，并具体描述了：数据如何由内容提供服务器传输至基站，以及在该过程中所涉及的对该数据的处理过程等内容。其中以基于LTE系统对基站移动网络中分发数据的方法及该方法所适用的架构为例进行说明，本领域普通技术人员应当能够根据下述示例类推得到其他通信系统中基站移动网络中分发数据的方法及该方法所适用的架构。
参见图7，为现有技术中提供的一种LTE系统的架构图。如图7所示，eNB通过S1接口连接核心网，核心网包括控制面网元MME(Mobile Management Entity，移动管理实体)和用户面网关SGW(Serving Gateway，服务网关)/PGW(PDN Gateway，PDN网关)等；具体的，eNB通过S1-C接口连接MME，并通过S1-U接口连接 SGW/PGW，以及通过U-u接口连接UE(User Equipment，终端设备)。另外，SGW/PGW通过SGi接口连接PDN(Packet Data Network，分组数据网。需要说明的是，其他相关网元如HSS(Home Subscriber Server，归属签约用户服务器)和PCRF(Policy and Charging Rules Function，策略和计费规则功能)等实体设备在图中未示出。
参见图8，为本发明实施例提供的基站移动网络中分发数据的方法所适用的一种系统架构，其中，图8所示的架构图是基于图7所示的LTE系统而绘制的。
图8所示的系统架构中包括内容提供服务器、CCS(Content Cache Server，内容缓存服务器)、CMS(Content Management Server，内容管理服务器)、GW(Gateway，网关)、GW controller(GW控制器)、MME和eNB。需要说明的是，由于下述未使用到SGW/PGW，因此图8中未示出SGW/PGW。其中：
内容提供服务器，具体可以是多媒体提供商、广告提供商或其他内容提供商存储业务的数据的服务器。
CCS，部署在互联网中的各处，用于缓存内容提供服务器提供的数据。CCS可以通过D1-U接口与内容提供服务器连接。CCS在CMS的控制下与内容提供服务器之间进行信息交互。CMS可以通过D3接口与CCS连接，并通过D1-C接口与内容提供服务器连接。其中，一个CMS可以连接一个或多个CCS。
GW，是LTE系统中的核心网网关。GW在GW controller的控制下与CCS之间进行信息交互，其中，GW可以通过D2-U接口与CCS连接。GW controller可以通过D4接口与MME连接，并通过D5接口与GW连接，以及通过D2-C接口与CMS连接。其中，一个GW controller可以连接一个或多个GW。
eNB，可以通过D6接口与MME连接，并通过D7接口与GW连接。可选的，D6接口可以使用原有的S1-C接口协议，D7接口可 以使用原有的S1-U接口协议。
需要说明的是，在本发明实施例中，缓存数据的设备(例如CCS和eNB)类似于背景技术中所述的CDN服务器。
还需要说明的是，对于3G系统和未来可能的5G系统也可以部署类似CMS和CCS，并且CMS可以通过D2-C连接GW controller，CCS可以通过D2-U接口核心网网关。另外，在3G系统中，核心网网关可以是GGSN(Gateway GPRS Support Node，网关GPRS支持节点)/SGSN(Servicing GPRS Support Node，GPRS服务支持节点)，在5G系统中，也可以部署类似的核心网网关。
另外需要说明是，图8中的各设备均是指逻辑功能实体，在实际实现时，可以将上述任一个或多个逻辑功能实体作为一个独立的网元，也可以将上述任意两个或两个以上逻辑功能集成在一个独立的网元，还可以在现有的网元上实现上述任一个或多个逻辑功能实体所具有的功能，本发明实施例对此不进行限定。下文中均以功能实体进行描述。
基于图8所示的系统架构，本发明实施例提供一种基站移动网络中分发数据的方法，该方法主要包括以下3个阶段：
阶段1、目标业务的数据由内容提供服务器传输至CCS的阶段
如图9所示，阶段1可以包括以下步骤S201-S204：
S201：CMS确定待分发的目标业务的相关信息。其中，该相关信息可以包括但不限于下述分发请求消息中的信息。
目标业务可以是内容提供商主动推送的业务，具体可以是任意区域性广播性或者多播性数据服务，例如商场广告内容服务商为商场内的客户主动推送促销信息或者广告信息，又如，体育场或展览馆等公众场所主动推送多媒体服务信息等。另外，目标业务还可以是通过在网络中设置的监测设备监测到的待推广的业务，例如热点业务等。
当目标业务是提供商主动推送的业务时，在步骤S201之前，该方法还可以包括：内容提供服务器向CMS发送数据分发请求消息，其中，数据分发请求消息中可以包括但不限于以下信息中的一种或几种：提供目标业务的服务商的标识、目标业务的类型(例如多媒体、图片、文本等)、目标业务的数据的信息(例如数据包的大小、视音频时长、时频分辨率、流媒体速率等)、数据发送对象的特征信息(例如区域范围、用户属性或用户标识等)、数据分发传输需求(例如数据有效时间、发送频率、最大等待延时、最多分发次数等)。
当目标业务是网络中设置的监测设备监测到的待推广的业务时，在步骤S201之前，该方法还可以包括：监测设备向CMS发送数据分发请求消息，其中，数据分发请求消息所包含的信息如上。另外，CMS也可作为监测设备。
S202：CMS为目标业务的数据分配CCS，并对该CCS的缓存配置进行管理。
一个CMS管理一个或多个CCS，CMS在确定目标业务的标识之后，根据一定的规则(例如负载均衡的规则等)从其管理的一个或多个CCS中确定缓存目标业务的数据的CCS。
CMS对CCS的缓存配置进行管理的过程可以包括以下步骤1)-3)：
1)CMS向CCS发送配置管理消息；其中，配置管理消息可以包括但不限于以下信息中的一种或几种：提供目标业务的服务商的标识、目标业务的标识、目标业务的概略数据、数据获取方式(如主动推送方式或被动拉取方式)、所占用的缓存空间的大小、缓存失效时间等。
其中，主动推送方式是指后续内容提供服务器向CCS主动推送目标业务的数据，该情况下，配置管理消息中还可以包括推送频率、推送时间、推送的内容服务器的标识等。在步骤S202之后，该方法 还可以包括：CMS向内容提供服务器回复数据分发请求消息的应答，其中，该应答中可以包括推送配置信息，例如推送频率、推送时间、该CCS的标识等。
被动拉取方式是指后续CCS向内容提供服务器拉取目标业务的数据，该情况下，配置管理消息中还可以包括拉取配置，例如拉取频率、拉取时间、拉取的地址信息(如URL地址)等。
2)CCS接收配置管理消息，按照配置管理消息配置相应的资源和数据传输模式，并向CMS回复配置管理消息应答；其中，该应答中包括所配置的资源信息和传输信息(例如缓存访问标识信息、缓存的地址和端口等)。
S203：CCS从内容提供服务器中获取目标业务的数据。
当获取数据的方式是主动推送方式时，内容提供服务器按照分发请求消息的应答中的推送配置向该CCS推送目标业务的数据。当获取数据的方式是被动拉取方式时，CCS可以按照配置管理消息中的拉取配置向内容提供服务器发送数据拉取请求消息，以使得内容提供服务器向CCS发送目标业务的数据。
S204：CCS缓存目标业务的数据。
需要说明的是，CCS中缓存的目标业务的数据是内容提供服务器提供目标业务的原始数据，即CCS不对目标业务的数据进行处理。可以理解为：CCS是基于业务从内容提供服务器中获取目标业务的数据，并基于业务缓存目标业务的数据。
另外需要说明的是，目标业务的数据从内容提供服务器传输并缓存至CCS的目的在于，能够使GW从与其距离较近的CCS上直接获取目标业务的数据，而不需要再从内容提供服务器获取目标业务的数据，从而提高响应速度。
阶段2、目标业务的数据由CCS缓存传输至GW的阶段
如图10所示，阶段2可以包括以下步骤S301-304：
S301：CMS向GW controller发送数据缓存请求消息。
其中，数据缓存请求消息中可以包括上述数据分发请求消息中所包含的任一种或多种信息。
S302：GW controller接收CMS发送的数据缓存请求消息，并根据该数据缓存请求消息配置GW，然后向CMS回复该数据缓存请求消息的应答。
一个GW controller管理一个或多个GW，GW controller可以根据目标业务所分布的地理区域范围等信息选择缓存目标业务的数据的GW。
GW controller配置GW的过程可以包括：GW controller向GW发送缓存配置消息，该缓存配置消息中可以包括但不限于以下信息中的一种或几种：目标业务的标识、目标业务的承载配置信息(例如数据的服务质量QoS，数据包大小信息，数据包的个数，分割级联配置，发送有效时间，重发周期，重发次数等)。GW根据缓存配置消息进行相应的配置之后，向GW controller回复缓存配置消息的应答。
本发明实施例对步骤S301-S302与上述步骤S202-S204之间的先后顺序不进行限定。
S303：CMS接收GW controller回复的数据缓存请求消息的应答，然后控制CCS向该GW发送目标业务的数据。
S304：CCS在CMS的控制下向该GW发送目标业务的数据。
S305：GW接收CCS发送的送目标业务的数据，并将目标业务的数据分为多个业务段，对每个业务段分配标识，然后缓存每个业务段的标识以及该业务段的数据。
具体的，可选的，GW可以首先对目标业务的数据进行PDCP(Packet Data Convergence Protocol，分组数据汇聚协议)层处理，例如，加密完整性保护、协议头压缩等处理；然后，将目标业务的 数据所在的数据包进行分段，生成多个业务段；接着，为每个业务段分配标识，例如，对多个业务段进行编号，并分配编码标识，生成CDCP(Cached Data Convergence Protocol，缓存数据汇聚协议)数据包头，其中，CDCP数据包头中可以包括目标业务的标识和业务段的标识等信息；最后，缓存携带有CDCP数据包头的业务段。另外，具体实现时，也可以将CDCP作为一个增强的功能，添加到现有的PDCP协议中；该情况下，GW在对目标月业务的数据进行PDCP层处理之后，即生成每个业务段的CDCP数据包头。
步骤S305可以理解为：GW是基于业务从CCS中获取目标业务的数据，并基于业务段缓存目标业务的数据。具体实现时，步骤S305中的“将目标业务的数据分为多个业务段，对每个业务段分配标识”的过程是可选执行的，例如，当目标业务的数据所占的存储空间较小时，GW可以不执行该过程。若不执行该过程，则在步骤S305具体可以为：GW接收CCS发送的送目标业务的数据，并缓存目标业务的数据，即GW也可以基于业务缓存目标业务的数据。
需要说明的是，在一些场景中，例如由同一个eNB基于业务段分发目标业务的数据的场景中，GW也可以不对目标业务进行分段以及为业务段分配标识，而由该eNB执行分段和分配标识的动作。一般地，当由多个eNB基于业务段分发目标业务的数据的场景中，为了避免多个eNB之间分段或分配标识的机制不统一而导致的后续终端设备不能有效识别每个业务段的问题，可以由GW对目标业务进行分段和为业务段分配标识。
阶段3、目标业务的数据由GW传输至eNB的阶段
如图11所示，阶段3可以包括以下步骤S401-S406：
S401：GW controller向MME发送数据缓存请求消息；其中，数据缓存请求消息中包含目标业务的标识信息，用于请求向MME管理的eNB中缓存目标业务的标识信息所指示的数据。
GW controller可以根据目标业务所分布的地理区域范围等信息确定MME。需要说明的是，一般地，GW与eNB之间的控制信息的交互过程，需要借助于该GW所属的GW controller和该eNB所属的MME来实现。所以GW controller需要首先确定管理分发目标业务的数据的eNB的MME。
具体实现时，一般地，GW controller与MME合设，该情况下，可以不执行步骤S401，直接执行步骤S402。
S402：MME接收GW controller发送的数据缓存请求消息，并根据该缓存请求消息配置分发节点，即配置分发目标业务的数据的设备。另外MME还可以向GW controller回复该数据缓存请求消息的应答。
这里的“分发节点”可以包括MME管理的所有eNB中的待发送目标业务的数据的一个或多个eNB，进一步地还可以包括直接从该一个或多个eNB接收目标业务的数据的终端设备、家庭基站、微基站、AP等，即首批接收节点。在该进一步可选的方式中，该方法还可以包括：MME将分发节点的标识发送给eNB，以使eNB在空口分发节点的标识，可选的，分发节点的标识可以包含在目标业务的配置消息中。
其中，待发送目标业务的数据的eNB可以是预先配置的，也可以是根据一定的规则确定的；直接从eNB接收目标业务的数据的终端设备可以是在这些终端设备签约时即确定的，也可以是预设时间段内在该eNB的覆盖范围之内的一个或多个终端设备。
数据缓存请求消息的应答中可以包括待发送目标业务的数据的eNB的标识。本发明实施例对步骤S401-S402，以及上述步骤S301-S302的先后顺序不进行限定。
S403：GW controller通过MME向eNB发送分发准备消息；其中，分发准备消息中包括目标业务的标识信息，用于指示eNB准备 接收目标业务的标识信息所指示的数据。
分发准备消息中还可以包括：目标业务的承载配置信息，分发节点的信息(例如分发节点的标识，分发区标识等)等。
S404：eNB接收MME转发的分发准备消息，并根据分发准备消息配置相应的资源，然后向GW controller回复分发准备消息的应答。
所配置的资源可以包括：数据缓存资源(例如内存缓存资源或磁盘缓存资源)，相应的传输资源(例如空口时频资源)，计算资源等。分发准备消息应答中可以包括已经配置好的资源的信息等。
S405：GW controller在接收到该分发准备消息的应答之后，控制GW向eNB发送目标业务的数据。
基于上述步骤S305(即GW对目标业务进行了分段)，在步骤S405中，目标业务的数据具体是：每个业务段的标识和该业务段的中的数据。即是按照每个业务段为单位进行发送的。
需要说明的是，本发明实施例中以目标业务的数据分发过程由一个eNB完成为例进行说明，具体实现时，可以包含多个eNB，该情况下，同一个业务的不同的业务段的数据可以由多个eNB分发给终端设备。
S406：eNB接收GW发送的目标业务的数据，并缓存目标业务的数据。
基于上述步骤S305(即GW对目标业务进行了分段)，在步骤S406中，eNB以业务段的形式缓存目标业务的数据，后续，目标业务的数据均以业务段的形式在分发节点和接收节点之间进行传输。
在步骤S406之后，该方法还可以包括：eNB通过广播或组播等方式分发目标业务的数据，或者，通过专用信令发送给相关的终端设备。另外，eNB还可以在空口分发目标业务的配置信息，其中，目标业务的配置信息可以包括：目标业务中的各业务段的标识，参 与分发目标业务的至少两个设备的优先级顺序等。
基于上述步骤S305中的具体实现方式，终端设备在接收到多个携带有CDCP数据包头的业务段之后，可以首先根据CDCP数据包头，并按照目标业务的数据的先后顺序，将该多个业务段组成连续的数据包；例如，终端设备根据业务段的CDCP数据包头所确定的多个业务段分别为：目标业务的业务段1、目标业务的业务段3、目标业务的业务段2，则终端设备可以将该多个业务段组成“目标业务的业务段1-目标业务的业务段2-目标业务的业务段3”。然后，终端设备可以去除每个业务段的CDCP数据包头，即得到目标业务的所有数据；进一步地，可以利用上层协议，例如PDCP协议，进行GW的逆操作过程，例如解密完整性保护、协议头解压处理等，从而得到内容提供服务器所提供的原始的目标业务的数据。
