Description

业务信息提供方法、 装置及网絡系统
本申请要求了于 2012年 6月 28日提交中国专利局，申请号为 201210218522.X、 发明名称为 "业务信息提供方法、 装置及网络系统" 的中国申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域 本发明实施例涉及通信技术， 尤其涉及一种业务信息提供方法、 装置及 网络系统。 背景技术 随着智能手机、 平板电脑等移动终端的大量使用， 通过无线接入技术下 载内容占用了很多的网络传输资源， 特别是热点内容的大量重复下载。 另夕卜， 大量用户同时向一个热点内容的业务源申请下载， 会造成业务源拥塞， 造成 很多用户下载不了， 或下载时间过长。
为了给用户终端（ User Equipment , 简称 UE )提供更高的访问速率、 更 小的时延， 同时降低访问源内容站点的传输成本， 艮多运营商将内容传送网 ( Content Delivery Network , 简称 CDN )技术应用到无线通信系统中， 但是 由于无线通信网络通常是一个特别定义的网络， 它不同于传统的 Internet, 将 CDN技术应用到无线通信网络时需要考虑 UE的移动性等特点及无线通信网 络特定的结构。 例如， 高速緩冲存储器 （Cache )点通常是接近于 UE的用户 平面的一个节点上， 通常是演进系统基站（eNodeB , 简称 eNB )上或无线网 络控制器（ Radio Network Controller, 简称 RNC )或基站控制器（ Base Station Controller ,简称 BSC )上，放到服务 GPRS支持节点（ Servicing GPRS Support Node , 简称 SGSN )或服务网关 Serving Gateway, 简称 SGW )上的内容加 速效果稍差。 有些运营商为了更好地支持 UE 的移动性及便于计费与管理， 将 Cache放到分组数据网网关 （ PDN Gateway , 简称 PGW )或网关 GPRS支 持节点 （ Gateway GPRS Support Node , 简称 GGSN )上， 或在 SGi或 Gi接 口上的一个专用的 Cache设备上。 为更接近无线用户， 提出一种在无线接入 网 （ Radio Access Network, 简称 RAN )侧部署 Cache设备的 RAN Cache, 即 RAN Cache功能通常是放到无线接入网节点中， 通常是 eNB、 RNC、 NodeB 或 BSC上。 在实现本发明实施例的过程中， 发明人发现现有技术中用户请求服务时， 如果 RAN Cache緩存有用户请求的资源， 则由 RAN Cache回复用户请求， 这 样不仅可以提高服务接入速率还可以节约骨干网的网络资源； 但当用户在高 速移动时候， 就可能跨 eNB、 RNC或 BSC, 触发切换。 此时， 如果当前源 RAN Cache的数据传输还未完成，按照传统的切换流程：如果源基站和目标基站之 间有接口， 则需要通过基站或基站控制器之间的接口把未完成的数据从源基 站转发到目标基站， 这会增加基站间接口流量的负担； 如果源基站和目标基 站之间没有接口， 则数据中断， 同时切换处理还会增加 RAN Cache系统的复 杂度。 发明内容 本发明实施例提供一种业务信息提供方法、 装置及网络系统， 用以避免 由于移动终端的移动状态的影响而导致的无线接入网高速緩冲存储器频繁切 换的问题， 保证业务信息发送的连续性。
一方面， 本发明实施例提供了一种业务信息提供方法， 包括：
无线接入网高速緩冲存储器接收来自移动终端的业务请求消息， 所述业 务请求消息包括业务标识和所述移动终端的移动状态信息；
若判断获知所述无线接入网高速緩冲存储器存储有与所述业务标识对应 的业务信息， 且所述移动状态信息满足预设的激活条件， 则所述无线接入网 高速緩冲存储器向所述移动终端返回确认信息， 并向所述移动终端发送所述 业务信息。

具体实施方式 图 1为本发明一实施例提供的业务信息提供方法的流程示意图， 如图 1所 示， 本实施例的业务信息提供方法可以包括：
步骤 101、 无线接入网高速緩冲存储器接收来自移动终端的业务请求消 息， 上述业务请求消息包括业务标识和上述移动终端的移动状态信息；
在本实施例的一个可选实施方式中， 上述移动终端的移动状态信息可以 包括移动方向和移动速率。
在本实施例的另一个可选实施方式中， 上述移动状态信息可以携带在上 述业务请求消息的头域中， 或携带在超文本传送协议请求的统一资源定位符 中。
由于移动终端的移动方向和移动速率会直接影响无线接入网高速緩冲存 储器可以提供服务的时间， 所以在移动终端的业务请求消息中携带移动状态 信息， 作为后续判断无线接入网高速緩冲存储器是否激活的一个条件。
步骤 102、若判断获知上述无线接入网高速緩冲存储器存储有与上述业务 标识对应的业务信息， 且上述移动状态信息满足预设的激活条件， 则上述无 线接入网高速緩冲存储器向上述移动终端返回确认信息， 并向上述移动终端 发送上述业务信息。
移动状态信息满足预设的激活条件的情况例如可为当移动终端的移动方 向为朝向当前服务的无线接入网设备时， 且其移动速率较小， 可以保证无线 接入网高速緩冲存储器有足够时间将业务信息完整传送给移动终端； 或者当 移动终端的移动方向为远离当前服务的无线接入网设备时， 但其移动速率较 小， 可以保证无线接入网高速緩冲存储器将业务信息传完整送给移动终端而 不会中断。
在图 1所述实施例的基础上， 本发明实施例的业务信息提供方法还可以包 括：
若判断获知上述无线接入网高速緩冲存储器没有存储上述业务标识对应 的业务信息， 和 /或上述移动状态信息不满足预设的激活条件， 则上述无线接 入网高速緩冲存储器向内容服务器转发上述业务请求消息， 以使上述内容服 务器为上述移动终端提供上述业务信息。
移动状态信息不满足预设的激活条件的情况例如可为移动终端的移动方 向为朝向当前服务的无线接入网设备时， 但其移动速率较大， 不能满足无线 接入网高速緩冲存储器将业务信息完整传送给移动终端 ； 或者移动终端的移 动方向为远离无线接入网设备， 且其移动速率较大， 不能满足无线接入网高 速緩冲存储器将业务信息传完整送给移动终端。
本实施例中， 通过携带在业务请求消息中的移动终端的移动状态信息， 判断当无线接入网高速緩冲存储器中存储有相应业务信息， 且其移动状态可 保证业务信息有足够时间完整传送， 不会因终端的移动而中断时， 激活相应 无线接入网高速緩冲存储器， 否则将移动终端的业务请求消息转发给内容服 务器， 该业务信息提供方法可以避免由于移动终端的移动状态的影响而导致 的无线接入网高速緩冲存储器频繁切换的问题， 保证业务信息发送的连续性。
为使得本发明实施例提供的业务信息提供方法更加清楚， 下面将以 RAN Cache在在 RNC、 NodeB中为例对本发明实施例提供的业务信息提供方法进 行详细说明。 图 2为本发明另一实施例提供的业务信息提供方法的流程示意 图， 如图 2所示， 本实施例的业务信息提供方法可以包括：
步骤 201、 RAN接收到 UE发送的业务请求信息， 业务请求信息中包括与 业务信息对应的业务标识；
例如可以为与视频下载请求对应的业务标识， 该业务请求信息例如可为 超文本传送协议（The Hypertext Transfer Protocol, 简称 HTTP ) GET请求： GET http://sever.example.com /media一 720p.flv HTTP/1.1
Accept: T Proxy-Connection: Keep-Alive
User-Agent: Mozi I la/4.0 (compatible; MSIE 6.0; Windows NT 5.1 ;
SV1)
Host: sever.example.com
Cookie:
步骤 202、 RAN Cache接收到 RAN发送的业务请求信息， 上述业务请求 消息包括业务标识和上述 UE的移动状态信息；
UE的移动状态信息具体可包括 UE的移动方向和移动速率， 图 3为本发明 另一实施例提供的业务信息提供方法中移动终端的移动状态信息的获取示意 图， 如图 3所示， UE的移动方向和移动速率的获取方法可以包括： RAN设备， 例如为基站利用两个时间点 t1、 t2时刻 UE上报的上行信号的时间提前量 TA计 算 UE两个时间点至基站间的径向距离 d1、 62, 同时基站收集 UE在两个时间 点 t1、 t2时刻分别与智能天线的夹角 L1、 L2, 利用三角形余弦定理可求得 UE 在时间 t2-t1内移动的距离 d , 此时速率大小为： d/( t2-t1) , UE的移动方向即 UE远离基站或者朝向基站移动可通过 d1、 d2之差的正负来判断。
图 4为本发明另一实施例提供的业务信息提供方法中移动终端相对于 RAN设备的移动状态的示意图， 如图 4所示， UE1和 UE2处于 RAN1与 RAN 2 之间， UE1此时的速度为 V1 , 相对 RAN1的速度为 V1 '， UE1朝向 RAN1方向移 动， 则认为此速度相对 RAN1为正数； UE2的速度为 V2, 相对 RAN1的速度为 V2', UE2向远离 RAN1的方向移动， 则认为此速度相对 RAN1为负数， V1 '和 V2'的绝对值即为 UE的移动速率， 其正负表示 UE的移动方向。
本步骤中， RAN设备，例如为基站需要将在 UE的移动状态携带在 UE的业 务请求消息中， 移动状态信息可以携带在上述业务请求消息的头域中。
移动状态信息可以携带在上述业务请求消息的头域中， 例如 H TT P Warning头域， HTTP Warning头域的格式例如可为：
Warning = "Warning" "：" 1 #warning-value
warning-value = warn-code SP warn-agent SP warn -text
[SP warn -date] warn-code = 3DIGIT
warn-agent = ( host [ "：" port ] ) | pseudonym ； the name or pseudonym of the server adding
； the Warning header, for use in debugging warn-text = quoted-string
warn-date = <"> HTTP-date < ">
将移动状态信息携带在业务请求消息的 Warning头域中的业务请求信息 例如可为：
GET http://sever.example.com /media一 720p.flv HTTP/1 .1
Accept: T
Proxy-Connection: Keep-Alive
User-Agent: Mozi I la/4.0 (compatible; MSIE 6.0; Windows NT 5.1 ;
SV1 )
Host: sever.example.com
Warning: 1 #1 17 UE1 V1 ' "052912 "
Cookie:
其中 Warning: 1 #1 17 UE1 V1， "052912"表示目前 UE1的移动状态 为 V1， 。
或者将移动状态信息携带在 HTTP请求的统一资源定位符 ( Uniform Resource Locator , 简称 URL ) 中的业务请求信息例如可为：
GET http://sever.example.com I UE1 V1， /media一 720p.flv HTTP/1 .1
Accept: T
Proxy-Connection: Keep-Alive
User-Agent: Mozi I la/4.0 (compatible; MSIE 6.0; Windows NT 5.1 ;
SV1 )
Host: sever.example.com
Cookie:
步骤 203、 若 RAN Cache判断获知 RAN Cache中存储有与上述业务标识 对应的业务信息， 且上述 UE的移动状态信息满足预设的激活条件， 则执行步 骤 204, 若 RAN Cache判断获知 RAN Cache没有存储与上述业务标识对应的 业务信息， 和 /或上述移动状态信息不满足预设的激活条件， 则执行步骤 205; 上述 RAN Cache预设的激活条件例如可为：若判断 UE的移动方向为朝向 当前服务的 RAN设备， 设置一速率门限为 V, 若 UE相对于 RAN设备的速率小 于 V, 则启动 RAN Cache, 否则不启动 RAN Cache; 若判断 UE的移动方向为 远离当前服务的 RAN设备， 设置另一速率门限为 V*, 若 UE相对于 RAN设备的 速率小于 V, 则启动 RAN Cache, 否则不启动 RAN Cache。
步骤 204、 RAN Cache向 UE返回业务提供确认信息， 并向 UE发送上述业 务信息；
步骤 205、 RAN Cache向内容服务器转发上述业务请求消息， 以使上述 内容服务器为上述移动终端提供上述业务信息。
具体可分为：
步骤 2051、 RAN Cache向网关节点（ SGSN/GGSN )转发业务请求消息； 步骤 2052、网关节点（ SGSN/GGSN )再向服务提供商 (Service Provider, 简称 SP)转发业务请求消息；
步骤 2053、 SP响应业务请求消息， 向网关节点（SGSN/GGSN )发送业 务提供确认信息；
步骤 2054、 网关节点（SGSN/GGSN )向 RAN Cache转发业务提供确认 信息；
步骤 2055、 RAN Cache向 UE转发业务提供确认信息。
在本实施例中， 当 UE的移动方向为朝向当前服务的 RAN设备时， 若 | V1 '| < V , 且请求的资源 media— 720p.flv在 RAN Cache中緩存， 则启动 RAN Cache, 由 RAN Cache响应终端的请求， 并向 UE发送 media_720p.flv的业务 信息；若 |V1 '| > V,或者请求的的资源 media— 720p.flv不在 RAN Cache中緩存， 或 |V1 '|>V且请求的的资源 media—720p.flv不在 RAN Cache中緩存则不启动 RAN Cache, 由 RAN Cache转发 UE的业务请求信息给内容服务器； 当 UE的 移动方向为远离当前服务的 RAN设备时， 若 |V1 '| < V*， 且请求的资源 media一 720p.flv在 RAN Cache中緩存， 则启动 RAN Cache, 由 RAN Cache响 应终端的请求， 并向 UE发送 media—720p.flv的业务信息； 若 |V1 '| > V*， 或者 请求的的资源 media— 720p.flv不在 RAN Cache中緩存， 或 |V1 '|> V*且请求的 的资源 media— 720p.flv不在 RAN Cache中緩存则不启动 RAN Cache, 由 RAN Cache转发 UE的业务请求信息给内容服务器， 需要说明的是： 如果 UE的移动 状态添加在 HTTP请求的 URL中，则由 RAN Cache删除业务请求信息中携带的 UE的移动状态信息后再将业务请求信息转发给内容服务器，如果 UE的移动状 态添加在业务请求消息的头域中， 则 UE的移动状态信息可删除也可不删除。
综上可知， 当 UE请求的业务信息在其对应的 RAN Cache中緩存， 且其移 动状态满足 RAN Cache预设的激活条件， 即其移动方向和速率可保证业务信 息的完整传送， 不会因为 UE的移动而中断时由 RAN Cache响应终端的请求， 并向 U E发送其请求的业务信息； 而当 U E请求的业务信息不在其对应的 RAN Cache中緩存， 和 /或移动状态信息不满足 RAN Cache预设的激活条件时， 由 RAN Cache转发 UE的业务请求信息给内容服务器，可以避免由于移动终端的 移动状态的影响而导致的无线接入网高速緩冲存储器频繁切换的问题， 保证 业务信息发送的连续性。

在本实施例的一个可选实施方式中， 上述处理模块 62还可以用于： 若判断获知上述无线接入网高速緩冲存储器没有存储上述业务标识对应 的业务信息， 和 /或上述移动状态信息不满足预设的激活条件， 则上述无线接 入网高速緩冲存储器向内容服务器转发上述业务请求消息， 以使上述内容服 务器为上述移动终端提供上述业务信息。
在本实施例的另一个可选实施方式中， 上述移动状态信息包括移动方向 和移动速率。
本实施例中， 处理模块 62根据移动终端的业务请求消息中业务标识和移 动状态信息判断是否为相应移动终端提供业务服务， 由于移动终端的移动方 向和移动速率会直接影响无线接入网高速緩冲存储器可以提供服务的时间， 所以本发明实施例提供的无线接入网高速緩冲存储器可以避免由于移动终端 的移动状态的影响而导致的无线接入网高速緩冲存储器频繁切换的问题， 保 证业务信息发送的连续性。
