背景技术
在无线网络中，回程(backhaul)用于核心网向基站侧传送语音和数据流量。具体而言，在长期演进(Long Term Evolution，LTE)网络中，backhaul就是演进基站(eNodeB)与演进型分组核心网(Evolved Packet Core，EPC)之间的链路。用户设备(User Equipment，UE)通过无线接入网络(Radio Access Network，RAN)接入移动网络，获得业务。
用户通过UE浏览网页时，UE向eNodeB发送业务请求以请求业务数据，该业务请求通过eNodeB发送到核心网侧的服务提供商(Service Provider，SP)服务器。核心网侧设备针对所述UE所请求的业务数据完成针对所述UE的计费。然后，SP服务器将UE所请求的业务数据发送给eNodeB，eNodeB将业务数据发送给UE。
这样，无论相同的UE还是不同的UE请求相同的业务数据时，SP服务器都需要向eNodeB发送一次该业务数据，导致Backhaul的数据流量非常大，占用了大量的Backhaul带宽资源。

具体实施方式
本发明实施例提供一种业务数据管理的方法，用于降低Backhaul的数据量，从而降低Backhaul带宽占用率。本发明实施例还提供了相应的装置及系统。以下分别进行详细说明。
为了使本技术领域的人员更好地理解本发明方案，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，所描述的实施例仅仅是本发明一部分的实施例，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，都应当属于本发明保护的范围。
本发明实施例所提供的业务数据管理的方法应用于无线通信系统，如图1所示，无线通信系统包括演进基站eNodeB、分组数据网关(Packet Data Network gateway，PGW)、服务网关(serving gateway，SGW)、网络优化代理(Network Optimization Agent，NOA)和网络优化控制器(Network Optimization Controller，NOC)和服务提供商(service provider，SP)服务器，所述NOA部署在演进基站eNodeB侧，所述NOC部署在核心网的分组数据网关(Packet Data Networkgateway，PGW)或者服务网关(serving gateway，SGW)之前，SP服务器用于提供业务数据，如：视频内容，网页内容等，用户设备可以为手机、笔记本电脑、个人计算机(Personal Computer，PC)等终端设备。
本发明实施例中的业务数据可以为视频数据、音频数据、网页数据等。
如图2所示，eNodeB与PGW(Packet Data Network Gateway,分组数据网关)/SGW(Serving Gateway，服务网关)之间的链路为回程(backhaul)链路，用户设备(User Equipment，UE)、eNodeB、NOA、NOC、PGW/SGW和SP服务器之间可通过传输控制协议(Transmission Control Protocol，TCP)、因特网互 联协议(Internet Protocol，IP)进行通信。NOA与NOC之间还可以通过用户数据报协议(User Datagram Protocol，UDP)或者通用无线分组业务通道协议(General Packet Radio Service Tunnel Protocol，GTP)，进行通信。
TCP头部的选项部分最长可以达到40byte，所以本发明实施例中，使用TCP协议中定义的Option字段，传输替换信息和索引信息。
参阅图3，本发明实施例提供的业务数据管理的方法的一实施例包括：
S100、UE1通过NOA和NOC向SP服务器发送业务请求，所述业务请求用于请求业务数据。
业务数据可以为视频数据、音频数据和网页数据等。
S105、SP服务器向NOC发送第一响应报文，所述第一响应报文中携带所述业务数据的第一数据分段。
S106、NOC针对所述业务数据对所述UE1进行计费。
S107、NOC向所述NOA发送所述第一响应报文，所述NOA将所述第一响应报文发送给UE1，所述第一响应报文中携带所述业务数据中的第一数据分段分段。
S110、NOA根据所述第一数据分段分段，计算所述业务数据的第一索引信息，并根据所述第一索引信息确定所述业务数据未命中。
计算第一索引信息可以采用信息摘要算法进行计算，也可以采用其他算法进行计算。
本发明实施例中，未命中是指NOA中未存储所述业务数据，则命中是指NOA中存储了所述业务数据，在存储时，第一索引信息与所述业务数据是对应存储的，所以，NOA计算得到第一索引信息后，就可以从第一索引信息与所述业务数据是对应关系中，确定所述业务数据在NOA中是否有存储。如果确定未存储，则确定未命中。
S115、对应存储第一索引信息和第一数据分段分段。
S116、UE向NOA发送TCP确认消息。
S117、NOA在确认消息中加入第一索引信息。
所述第一索引信息可以添加到TCP的Option字段。
S120、SP服务器通过响应报文继续发送所述业务数据中的数据分段，所述NOC将所述数据分段发送给所述NOA，所述NOA再将所述数据分段发送给UE。
S125、NOA将所述业务数据的数据分段和第一索引信息对应存储。
实际上，每次可以只发送一段数据分段，发送的次数可以有多次，但每次的过程与S120和S125相同，本处不做过多赘述。
NOA对应存储第一索引信息和数据分段时可以通过会话标识，查找该数据分段所对应的第一索引信息。在一次会话过程中，会话标识是唯一的。
可以将NOA存储数据分段的过程理解为是业务数据注入的过程，业务数据通常是逐步注入的，对于字节数非常少的数据也可以是一次完成注入的。
S130，当NOA注入所述业务数据的过程中，UE2向SP服务器发送请求，请求与UE1相同的业务数据。
S135、SP服务器向NOC发送第一响应报文，响应报文中携带所述业务数据的第一数据分段分段。
S136、NOC针对所述业务数据对所述UE2进行计费。
S137、NOC向所述NOA发送所述第一响应报文，所述NOA将所述第一响应报文发送给UE2，所述第一响应报文中携带所述业务数据的第一数据分段分段。
S140、NOA根据所述第一数据分段，计算所述业务数据的第一索引信息，并根据所述第一索引信息确定所述业务数据命中。
S50、UE2向NOA发送TCP确认消息。
S155、NOA向NOC发送TCP确认消息，在TCP确认消息的option字段添加命中指示信息，以使所述NOC根据所述命中指示信息，用预置的替换信息替换所述业务数据中的数据分段，所述预置的替换信息所占带宽小于所述数据分段所占带宽，。
替换信息可以是一个标识，也可以是一个索引。
S160、NOC向SP服务器发送TCP确认消息。
S165、SP服务器向NOC通过响应报文继续发送所述业务数据中的数据分 段。
S170、NOC根据所述命中指示信息，在所述响应报文中用预置的替换信息替换所述数据分段。
所述预置的替换信息所占带宽小于所述数据分段所占带宽。
本发明实施例中，替换信息可以只有4bytes或者更小的字节,所占用的回程带宽远远小于数据分段所占用的带宽，因此，可以减少Backhaul的数据量，降低带宽占用率。
S175、NOC向NOA发送响应报文，所述响应报文携带所述替换信息。
