目前, 上网的用户数越来越多, Web站点的数量继续在增加, 可供访问 的资源日趋丰富, 特别是文本、 图像、 音乐、 广告、 流媒体、 动画等大量涌 现; 网上业务量成倍递增, 造成了对网络带宽的大量需求, 并且网络访问的 延迟与等待总是普遍存在, 这些情况导致了网络拥塞, 服务器过载, 网上应 用等待时间过长等诸多问题, 使整个互联网内容传送性能下降。
为了緩解网络拥塞, 提高用户访问网站的响应速度, CDN ( Content Delivery Network, 内容分发网络 )技术应运而生。 CDN是建立在现有 IP网 络基础结构之上的一种增值网络, 是在应用层部署的一种网络架构, 其功能 是将多点负载均衡、 路由或緩存技术结合起来, 利用智能分配技术, 将内容 根据来访用户的地点,按照就近访问的原则分配到多个节点。 利用 CDN技术 可以解决由于网络带宽小、 用户访问量大、 网点分布不均等原因所造成的用 户访问网站响应速度慢的问题。
随着网络技术和无线通信设备的迅速发展, 人们迫切希望能随时随地从 Internet 上获取信息。 针对这种情况, 移动宽带互联网 ( MBB , Mobile Broad-Band )成了全球电信市场增长最主要的动力, 智能手机、 平板电脑、 新类型的移动设备如游戏机、 导航系统、 监测工具等, 正不断融入 MBB, 进 一步推动移动数据增长, 预计未来几年 MBB将快速超过因特网, MBB将会 爆炸式增长, 这样基站到核心网之间的回程线路(Backhaul )传输将承受巨 大的流量沖击。
由于 CDN网络通常部署在核心网之后,虽然在一定程度上提高了用户访 问网站的响应速度, 但对基站到核心网之间的回程线路传输没有任何改善, 如何有效地降低基站到核心网之间的回程线路传输压力, 提高移动宽带互联 网用户访问网站的响应速度, 目前还没有一种有效的解决方案。
发明内容
针对上述现有技术存在的问题, 提供一种提高移动互联网用户访问速度 的方法及设备, 以有效地降低基站到核心网之间的回程线路传输压力, 提高 移动互联网用户访问分组域业务的响应速度。
为此, 提供了一种提高移动互联网用户访问速度的方法, 包括: 基站接收用户访问分组域业务的请求;
如果所述基站用于保存分组域业务内容的本地緩存中有所述用户请求的 分组域业务内容, 则从所述基站用于保存分组域业务内容的本地緩存中获取 所述用户请求的分组域业务内容, 将从所述基站用于保存分组域业务内容的 本地緩存中获取的分组域业务内容发送给所述用户; 和 /或,
如果所述基站用于保存分组域业务内容的本地緩存中没有所述用户请求 的分组域业务内容,则从分组域业务服务器获取用户请求的分组域业务内容, 将从所述分组域业务服务器获取的内容发送给所述用户。
一种基站, 包括: 本地緩存单元、 请求接收单元、 检查单元、 请求响应 单元, 还包括: 第一内容获取单元, 和 /或第二内容获取单元;
所述本地緩存单元, 用于保存分组域业务内容;
所述请求接收单元, 用于接收用户访问分组域业务的请求;
所述检查单元, 用于根据所述用户访问分组域业务的请求, 检查所述本 地緩存单元中是否有用户请求的分组域业务内容;
所述第一内容获取单元, 用于在所述检查单元检查到所述本地緩存单元 中有用户请求的分组域业务内容时, 从所述本地緩存单元中获取用户请求的 分组域业务内容;
所述第二内容获取单元, 用于在所述检查单元检查到所述本地緩存单元 中没有用户请求的分组域业务内容时, 从分组域业务服务器获取用户请求的 分组域业务内容;
所述请求响应单元, 用于将所述第一内容获取单元从本地緩存单元获取 的分组域业务内容或者所述第二内容获取单元从分组域业务服务器获取的分 组域业务内容发送给所述用户。
上述的提高移动互联网用户访问速度的方法及设备, 在基站接收到用户 访问分组域业务的请求后, 如果基站中用于保存分组域业务内容的本地緩存
中有用户请求的分组域业务内容, 则基站可以直接从本地緩存中获取用户所 需的内容, 从而可以有效地降低基站到核心网之间的回程线路传输压力, 提 高移动互联网用户访问分组域业务的响应速度。

具体实施方式
为了使本技术领域的人员更好地理解本发明实施例的方案, 下面结合附 图和实施方式对本发明实施例作进一步的详细说明。
本发明实施例提高移动宽带互联网用户访问速度的方法及设备, 在基站 上部署用于保存分组域业务内容的本地緩存, 基站接收用户访问分组域业务 的请求后, 如果基站的该本地緩存中有用户请求的分组域业务内容, 则可直 接从该本地緩存中获取用户请求的分组域业务内容, 从而可以有效地降低基 站到核心网之间的回程线路传输压力, 提高移动宽带互联网用户访问访问分 组域业务的响应速度。
如图 1所示, 是本发明实施例提高移动宽带互联网用户访问速度的方法
的流程图。
图 1所示流程包括以下步骤:
步骤 101 , 基站接收用户访问分组域业务的请求。
该分组域业务的请求可以是 HTTP ( HyperText Transfer Protocol, 超文本 传输协议)或 FTP ( File Transfer Protocol, 文件传输协议 )等协议承载的网 页浏览、 下载、 视频浏览请求等, 具体可以按照 HTTP、 FTP协议标准, 比 如所述请求可以是一个 URL ( Universal Resource Locator, 统一资源定位符)。
在现有的基站中, 基站通常只识别 FP ( Frame Protocol, 帧协议)帧, 在 RNC ( Radio Network Controller, 无线网络控制器 )上才会将 FP帧解析并识 别封装在 FP帧中的 IP报文,但目前无线网络扁平化架构可以将 RNC这一功 能下移至基站, 而 LTE ( Long Term Evolution, 长期演进)网络中, 增强型基 站 eNodeB融合了基站以及基站控制器的功能。
FP帧解析的功能下移到基站之后, 对于包含分组域业务的 FP帧, 基站 能够解析并识别封装在 FP帧中的 IP报文, 而对于电路域业务的 FP帧,基站 的处理流程与现有的处理流程相同, 不受影响。
因此,本发明实施例中的基站可以是具有这种能够识别封装在 FP帧中的 IP报文功能的基站, 从而能够识别 HTTP、 或 FTP请求。
步骤 102, 基站检查用于保存分组域业务内容的本地緩存中是否有用户 请求的分组域业务内容; 如果是, 则执行步骤 103; 否则, 执行步骤 104。
具体地, 在基站检查用于保存分组域业务内容的本地緩存中是否有用户 请求的分组域业务内容时, 可以通过 URL做索引, 相应地, 在将所述内容保 存到所述本地緩存时, 需要保存所述内容对应的 URL。
步骤 103 , 基站从用于保存分组域业务内容的本地緩存中获取用户请求 的分组域业务内容; 然后执行步骤 105。
步骤 104, 基站从分组域业务服务器获取用户请求的分组域业务内容。 步骤 105 , 基站将从用于保存分组域业务内容的本地緩存中获取的内容 或从分组域业务服务器获取的内容发送给上述用户。
需要说明的是, 上述流程中的步骤 103为可选步骤, 也就是说, 本发明 的另一实施例也可以只针对上述步骤 102中基站检查到用于保存分组域业务
内容的本地緩存中没有用户请求的分组域业务内容的情况进行处理。
另外, 上述流程中的步骤 104也为可选步骤, 也就是说, 本发明的另一 实施例也可以只针对上述步骤 102中基站检查到用于保存分组域业务内容的 本地緩存中有用户请求的分组域业务内容的情况进行处理。
在本发明实施例中, 基站接收到用户访问分组域业务的请求后, 如果基 站用于保存分组域业务内容的本地緩存中有用户请求的分组域业务内容, 则 基站可以直接从本地緩存中获取用户所需的分组域业务内容, 从而可以有效 地降低基站到核心网之间的回程线路传输压力, 提高移动互联网用户访问分 组域业务的响应速度。
另外, 本发明实施例的方法还可进一步包括: 如果所述基站从所述分组 域业务服务器获取的分组域业务内容为热点内容, 则将所述分组域业务内容 存储在所述基站用于保存分组域业务内容的本地緩存中。
比如, 在图 1所示的流程中, 在步骤 104和步骤 105之间还可进一步包 括以下步骤: 基站根据预设的规则判断步骤 104中基站获取的内容为热点内 容, 则该内容存储在该基站用于保存分组域业务内容的本地緩存中。
再比如, 在图 1所示的流程中, 在步骤 105之后还可进一步包括以下步 骤: 基站根据预设的规则判断步骤 104中基站获取的内容为热点内容, 则该 内容存储在该基站用于保存分组域业务内容的本地緩存中。
这样, 基站在从分组域业务服务器获取用户请求的分组域业务内容后, 确定该内容为热点内容, 并将该热点内容存储在该基站用于保存分组域业务 内容的本地緩存中, 在后续有用户访问该内容时, 基站可以直接从该本地緩 存中获取相应内容。
对于如何确定所述内容是否为热点内容, 在实际应用中, 可以有多种判 断方式, 对此本发明实施例不 #文限定, 下面仅对此举例说明。
比如, 可以根据以下任意一项或多项统计参数来确定所述内容是否为热 点内容:
( 1 )访问次数; (2 )访问文件大小。
其中, 文件大小和热度的关系体现主要取决于基站上的緩存策略, 如存 储容量有限, 由于较小文件占用的存储空间更小, 因此可以设定增加所述内
容的热度值时, 小文件对应的内容的热度增加一个较大的值, 也就是小文件 更容易变热; 或者基于相反的考虑, 如果存储容量足够大, 较大文件一旦命 中, 对命中的流量增加较多, 可以设定增加所述内容的热度值时, 大文件对 应的内容的热度增加一个较大的值, 也就是大文件更容易变热。
在具体应用中, 为了进行热度统计, 可以记录用户每次访问的 URL、 文 件大小、 语言等信息, 这些信息构成了用户访问内容的元数据, 用于标识内 容资源。
根据这些记录, 可以统计访问文件的总数、 总访问次数、 已緩存的访问 文件数等信息, 根据这些统计信息及热度计算策略(如按照访问次数统计), 计算用户访问内容的热度, 将计算结果与统计的平均热度进行比较, 高于平 均热度一定百分比, 比如由冷变热高于平均热度 5%, 则确定相应内容为热点 内容, 这样可以避免冷热波动变化; 否则, 仅记录本次访问的相关信息。
如果需要考虑访问文件大小这一参数来计算用户访问内容的热度, 则在 进行热度计算时, 可以分层处理, 即按照 URL和元数据分别计算出一个热度 值, 同一个 URL的不同元数据的热度和应该小于等于 URL的热度值。 然后, 根据得到的两个热度值来确定用户访问内容的热度, 比如, 可以对这两个热 度值进行加权来计算用户访问内容的热度, 当然也可以采用其他计算方法, 对此本发明实施例不做限定。
当然, 在实际应用中, 对用户访问的内容是否为热点内容的判断还可以 有其他各种不同的方式, 具体实现过程可以参照现有的一些处理方式, 在此 不再——举例说明。
上面步骤 104提到, 在基站用于保存分组域业务内容的本地緩存中没有 用户请求的分组域业务内容的情况下, 该基站可以从分组域业务服务器获取 用户请求的分组域业务内容。 具体地, 基站可以将上述用户访问分组域业务 的请求转发给与基站通过有线或者无线方式相连的接入设备, 该接入设备与 互联网相连, 可以访问互联网, 该基站接收该接入设备根据所述用户访问分 组域业务的请求从分组域业务服务器获取的用户请求的分组域业务内容。
与互联网相连的接入网设备可以是,比如 LTE中的核心网设备,或者 RNC 等设备; 还可以是其它可以直接访问互联网的固网接入设备。
另外, 上述与互联网相连的接入设备在接收到分组域业务服务器返回的 内容后, 除了将该内容返回给所述基站外, 还可进一步确定该内容是否为上 面提到的热点内容, 如果是, 则同样可以将该内容存储在该接入设备用于保 存分组域业务内容的本地緩存中。 该接入设备在其负荷低于预设值(比如 30% ) 时将自己用于保存分组域业务内容的本地緩存中緩存的内容推送给其 他基站, 并通知所述其他基站保存该内容。 这样, 在所述其他基站后续有用 户访问同样内容时, 可以直接从该本地緩存中获取相应内容, 有效地提高用 户访问分组域业务的响应速度。
下面进一步举例详细说明本发明实施例提高移动互联网用户访问速度的 方法另一实施例。
如图 2所示, 是本发明实施例提高移动互联网用户访问速度的方法的流 程图。
在该实施例中,所述基站通过 RNC从分组域业务服务器获取用户请求的 分组域业务内容, 该流程包括以下步骤:
步骤 201 , 基站接收用户访问分组域业务的请求。
步骤 202, 基站检查用于保存分组域业务内容的本地緩存中是否有用户 请求的分组域业务内容; 如果是, 则执行步骤 203; 否则, 执行步骤 204。
步骤 203 , 基站从用于保存分组域业务内容的本地緩存中获取用户请求 的分组域业务内容; 然后执行步骤 205。
步骤 204, 基站通过 RNC及核心网从分组域业务服务器获取用户请求的 分组域业务内容, 并且从分组域业务服务器获取的分组域业务内容为热点内 容时, 将该分组域业务内容存储在基站用于保存分组域业务内容的本地緩存 中。
在该步骤中, 基站首先将访问分组域业务的请求发送给 RNC, 然后接收 RNC根据所述用户访问分组域业务的请求从分组域业务服务器获取的用户请 求的分组域业务内容。
相应地, RNC接收到基站发送的用户访问分组域业务的请求后, 通过核 心网设备从分组域业务服务器获取用户请求的分组域业务内容, 然后将该内 容发送给上述基站。
需要说明的是, 在基站将上述用户访问分组域业务的请求发送给 RNC 时, 需要将该请求中包含的移动终端的 IP地址与端口号转换为基站的 IP地 址与端口号, 此过程可以是一个标准的 NAT ( Network Address Translation, 网络地址转换 )或 NAPT ( Network Address Port Translation, 网络端口地址转 换)过程, 在此不再详细描述。
步骤 205 , 基站将从用于保存分组域业务内容的本地緩存中获取的分组 域业务内容或通过 RNC及核心网从分组域业务服务器获取的分组域业务内 容发送给所述用户。
在该实施例中, 还可以在 RNC中设置本地緩存, RNC从分组域业务服 务器获取用户请求的分组域业务内容后, 确定该分组域业务内容是否为热点 内容, 如果是热点内容, 则将该分组域业务内容存储在 RNC用于保存分组域 业务内容的本地緩存中。 RNC可以选择在其负荷低于一定值时将緩存的内容 推送给其他基站, 并通知所述其他基站保存所述内容。
上述 RNC确定从分组域业务服务器获取用户请求的分组域业务内容是 否为热点内容的实现方式与基站确定热点内容的实现方式类似, 具体可以参 照前面基站对获取的内容是否为热点内容的处理过程, 在此不再赘述。
如图 3所示, 是本发明实施例提高移动互联网用户访问速度的方法的另 一流程图。
在该实施例中, 基站通过固网接入设备从分组域业务服务器获取用户请 求的分组域业务内容, 该流程包括以下步骤:
步骤 301 , 基站接收用户访问分组域业务的请求。
步骤 302, 基站检查用于保存分组域业务内容的本地緩存中是否有用户 请求的分组域业务内容; 如果是, 则执行步骤 303; 否则, 执行步骤 304。
步骤 303 , 基站从用于保存分组域业务内容的本地緩存中获取用户请求 的分组域业务内容; 然后执行步骤 305。
步骤 304, 基站通过固网接入设备从分组域业务服务器获取用户请求的 分组域业务内容, 并且从分组域业务服务器获取的分组域业务内容为热点内 容时, 将该分组域业务内容存储在基站用于保存分组域业务内容的本地緩存 中。
基站可以通过相应的接口比如 Gi口接入到固网接入设备中,所述固网接 入设备可以是 xDSL(如 ADSL、 ADSL2、 ADSL2+、 VDSL, VDSL2、 VDSL2+、 SHDSL等)、 xPON (如 EPON、 GPON等)、 P2P Ethernet等。 在这种情况下, 基站可以通过 Gi口解析出 IP数据包, 并将解析出的 IP数据包发送给上述固 网接入设备; 而固网接入设备可以根据接收的 IP数据包寻址并获取用户请求 的分组业务内容, 并返回给基站。
需要说明的是, 在基站通过固网接入设备从分组域业务服务器获取用户 请求的分组域业务内容的过程中, 需要将上述请求中包含的移动终端的 IP地 址与端口号转换为基站的 IP地址与端口号, 此过程可以是一个标准的 NAT 或 NAPT过程, 在此不再详细描述。
步骤 305 , 基站将从用于保存分组域业务内容的本地緩存中获取的分组 域业务内容或通过固网接入设备从分组域业务服务器获取的分组域业务内容 发送给上述用户。
上述图 2和图 3所示流程分别示出了基站通过不同类型的其他设备从分 组域业务服务器获取用户请求的分组域业务内容的过程。 需用说明的是, 在 实际应用中, 如果基站能够同时支持与 RNC及上述固网设备的通信, 则在从 分组域业务服务器获取用户请求的分组域业务内容时, 可以根据需要或设定 的策略选择不同的路径。
在上述各实施例中, 还可进一步包括以下步骤:
基站从签约的分组域服务提供商获取热点内容, 比如基站在负荷较低时 主动获取签约的分组域服务提供商提供的热点内容, 并将该内容存储在基站 用于保存分组域业务内容的本地緩存中。
需要说明的是, 在上述各实施例中, 对基站是否要将从分组域业务服务 器获取的分组域业务内容保存到基站用于保存分组域业务内容的本地緩存的 判断, 除了需要确定所述内容是否为热点内容之外, 还可进一步设定相应的 存储策略, 只对符合该存储策略要求的热点内容进行存储。 所述存储策略可 以根据需要来设定, 比如:
( 1 )协议存储策略: 即按协议的约定确定对用户请求的响应是否可以从 本地緩存中获取相应的内容。
( 2 )应用存储策略: 即根据用户请求的分组域业务内容的应用来确定是 否可以从本地緩存中获取相应的内容, 例如, 对动态内容的网页不做緩存, 即判断是否为动态网页, 或者带应用层参数的网页。
( 3 )用户选择策略: 即可以由用户进行配置, 实现动态的緩存策略管理, 比如, 用户可以选择只对某些 ISP提供的网页实现加速功能。
当然, 在实际应用中, 还可以有其他存储策略, 对此本发明实施例不做 限定。
相应地, 本发明实施例还提供一种基站, 如图 4所示, 是本发明实施例 基站的一种结构示意图。
在该实施例中, 所述基站包括: 本地緩存单元 401、 请求接收单元 402、 检查单元 403、 请求响应单元 406, 还包括: 第一内容获取单元 404, 和 /或第 二内容获取单元 405。 其中:
本地緩存单元 401 , 用于保存分组域业务内容;
请求接收单元 402, 用于接收用户访问分组域业务的请求;
检查单元 403 , 用于根据所述用户访问分组域业务的请求, 检查本地緩 存单元 401中是否有用户请求的分组域业务内容;
第一内容获取单元 404, 用于在所述检查单元 403检查到所述本地緩存 单元 401中有用户请求的分组域业务内容时, 从所述本地緩存单元 401中获 取用户请求的分组域业务内容;
第二内容获取单元 405 , 用于在所述检查单元 403检查到所述本地緩存 单元 401 中没有用户请求的分组域业务内容时, 从分组域业务服务器获取用 户请求的分组域业务内容;
请求响应单元 406, 用于将第一内容获取单元 404从本地緩存单元 401 获取的分组域业务内容或者第二内容获取单元 405从分组域业务服务器获取 的分组域业务内容发送给所述用户。
在本发明实施例中, 第二内容获取单元 405可以通过与互联网相连的接 入设备从分组域业务服务器获取用户请求的分组域业务内容。 第二内容获取 单元 405 将上述用户访问分组域业务的请求发送给与互联网相连的接入设 备, 并接收该接入设备根据上述用户访问分组域业务的请求从分组域业务服
务器获取的用户请求的分组域业务内容。 第二内容获取单元 405可以通过有 线或者无线方式与接入设备相连。
比如,第二内容获取单元 405可以通过 RNC及核心网从分组域业务服务 器获取用户请求的分组域业务内容。
再比如, 第二内容获取单元 405还可以通过可以直接访问互联网的固网 接入设备从分组域业务服务器获取用户请求的分组域业务内容。 基站可以通 过相应的接口比如 Gi 口接入到固网接入设备中, 所述固网接入设备可以是 xDSL (如 ADSL, ADSL2、 ADSL2+、 VDSL, VDSL2、 VDSL2+、 SHDSL 等)、 xPON (如 EPON、 GPON等)、 P2PEthemet等。
需要说明的是, 在基站通过上述固网接入设备从分组域业务服务器获取 用户请求的分组域业务内容的过程中, 需要将上述请求中包含的移动终端的 IP地址与端口号转换为基站的 IP地址与端口号, 此过程可以是一个标准的 NAT或 NAPT过程, 在此不再详细描述。
本发明实施例的基站, 在接收到用户访问分组域业务的请求后, 如果基 站用于保存分组域业务内容的本地緩存中有用户请求的分组域业务内容, 则 基站可以直接从本地緩存中获取用户所需的分组域业务内容, 从而可以有效 地降低基站到核心网之间的回程线路传输压力, 提高移动互联网用户访问分 组域业务的响应速度。
如图 5所示, 是本发明实施例基站的另一种结构示意图。
与图 4所示实施例的区别在于, 该实施例的基站还包括:
热度判断单元 407, 用于确定第二内容获取单元 405从分组域业务服务 器获取的分组域业务内容是否为热点内容, 并在该分组域业务内容为热点内 容时, 通知第二内容获取单元 405将该分组域业务内^ "储到本地緩存单元 401 中, 从而可以在后续有用户访问该内容时, 基站可以直接从该本地緩存 中获取相应内容。
需要说明的是,上述热度判断单元 407具体可以在第二内容获取单元 405 获取用户请求的分组域业务内容后进行判断处理,也可以在请求响应单元 406 将该分组域业务内容发送给上述用户后进行判断处理, 对此本发明实施例不 做限定。
对于热度判断单元 407如何确定第二内容获取单元 405获取的分组域业 务内容是否为热点内容可以有多种实现方式, 具体可参照前面本发明实施例 提高移动互联网用户访问速度的方法中的描述, 在此不再赘述。
本发明实施例的基站, 从分组域业务服务器获取用户请求的分组域业务 内容后, 如果该分组域业务内容为热点内容, 则将其保存在本地緩存单元中, 从而在后续有用户访问该内容时, 可以直接从本地緩存单元中获取用户该内 容, 有效地降低了基站到核心网之间的回程线路传输压力, 提高了移动互联 网用户访问网站的响应速度。
为了进一步降低基站到核心网之间的回程线路传输压力, 在本发明实施 例中, 所述第二内容获取单元 405 , 还可以从签约的分组域服务提供商获取 热点内容, 比如在基站负荷较低时主动获取签约的分组域服务提供商提供的 热点内容, 然后将该内容存储到本地緩存单元 401 中。 这样, 对于一些热点 内容, 即使用户没有请求过, 也可以由基站主动从互联网中获得, 从而在后 续有用户访问该内容时, 基站可以直接从本地緩存单元中获取用户所需的内 容, 降低基站到核心网之间的回程线路传输压力, 提高移动互联网用户访问 网站的响应速度。
下面进一步举例详细说明本发明实施例的基站在实际中的应用过程。 例 1
如图 6所示, 是本发明实施例的基站的应用实例 1示意图。
在该实施例中, 基站和无线网络控制器均部署本地 Cache (緩存), 用于 保存分组域业务内容。 具体工作过程主要如下:
1. 当移动终端 1向基站发送请求, 例如 HTTP网页浏览、 下载、 视频浏 览请求等, 基站查找本地 Cache后没有终端请求的内容, 经过传统的无线网 络控制器、 核心网到 Internet (因特网 )获取用户请求的分组域业务内容, 无 线网络控制器分析内容热度, 如果是热点内容, 则通知用户所属的基站存储 相应内容。
2. 后续基站其他用户访问同样内容时, 基站直接提供 Cache服务, 不需 要再次经过无线网络控制器、核心网到 Internet获取内容,从而节省传输成本。
3. 空闲时无线网络控制器主动推送热点内容到基站并緩存。
例 2
如图 7所示, 是本发明实施例的基站的应用实例 2示意图。
在该实施例中, 基站独立部署本地 Cache, 用于保存分组域业务内容。 具体工作过程主要如下:
1. 基站监听用户请求内容, 当请求到达后, 基站查找本地 Cache后没有 终端请求的内容, 经过传统的网络, 通过无线网络控制器、 核心网到 Internet 获取用户请求的分组域业务内容, 基站分析内容热度, 如果是热点内容, 则 存储相应内容。
2. 后续基站其他用户访问同样内容时, 基站直接提供 Cache服务, 不需 要再次经过无线网络控制器、核心网到 Internet网获取内容,从而节省传输成 本。
例 3
如图 8所示, 是本发明实施例的基站的应用实例 3示意图。
在该实施例中, 基站独立部署本地 Cache, 用于保存分组域业务内容。 具体工作过程主要如下:
1. 基站监听用户请求内容, 请求到达基站后, 如果基站没有终端请求的 内容, 则基站通过自身的接口 (例如 GI 口 )通过附近的固网接入设备接入 Internet, 获得用户请求的分组域业务内容, 从而减轻基站到控制器及核心网 之间的传输成本。
2. 基站进行内容热度分析, 如果所述内容为热点内容, 则基站存储相 应内容到基站 Cache。
3. 后续基站其他用户访问同样内容时, 基站直接提供 Cache服务, 从而 节省传输成本。
4. 基站可以在空闲的时候主动通过自身的接口 (例如 GI口)获取签约 ISP内容, 并将热点内容存储到基站 Cache。
例 4
如图 9所示, 是本发明实施例的基站的应用实例 4示意图。
在该实施例中, 基站和无线网络控制器均部署本地 Cache, 用于保存分 组域业务内容。 基站既可以通过无线网络控制器、 核心网从互联网服务器获
取的用户请求的分组域业务内容, 也可以通过固网设备从互联网服务器获取 的用户请求的分组域业务内容。
工作过程主要如下:
1. 基站监听用户请求内容, 请求到达基站后, 基站查找 Cache中没有终 端请求的内容, 则基站通过自身的接口 (例如 GI口 )通过附近的固网接入设 备接入 Internet, 获得用户请求的分组域业务内容, 从而减轻基站到无线网络 控制器及核心网之间的传输成本。
2.基站和 /或无线网络控制器分析内容热度, 如果为热点内容, 则基站存 储相应内容。
3. 后续基站其他用户访问同样内容时, 基站直接提供 Cache服务, 从而 节省传输成本。
4. 基站可以在空闲的时候主动通过自身的接口 (例如 GI口)获取签约 ISP ( Internet Service Provider, 互联网服务提供商 )提供的内容, 并将热点内 容存储到基站 Cache, 同时也可以采用无线网络控制器在空闲时主动推送高 热内容到基站 Cache。
可见, 无论上述哪种方式, 都可以有效地降低基站到核心网之间的回程 线路传输压力, 提高移动互联网用户访问网站的响应速度。
以上对本发明实施例进行了详细介绍, 本文中应用了具体实施方式对本 发明进行了阐述, 以上实施例的说明只是用于帮助理解本发明的方法及设备; 同时, 对于本领域的一般技术人员, 依据本发明的思想, 在具体实施方式及 应用范围上均会有改变之处, 综上所述, 本说明书内容不应理解为对本发明 的限制。
