请参照图 1 , 在 LTE通信系统网络架构的基石出上, 本发明实施例增加了 MEAS和 MEAS-SF。其中, MEAS部署在接入网侧, 靠近基站 ( eNodeB ) , 其上承载了了 SP提供内容、 应用服务等业务; MEAS-SF可以部署在核心 网侧, 设置在分组数据网关 (Packet Data Network Gateway, 以下简称 P-GW ) 与服务网关 ( Serving Gateway, 以下简称 S-GW )之间, MEAS-SF 上部署有用户层面的通用分组无线业务( General Packet Radio Service , 以下 简称 GPRS ) 隧道协议( GPRSTimnellingProtocolfortheuserplane, 以下简称 GTPU ) 代理, 协议层自上而下包括: 传输层协议 /用户数据报协议 ( Transmission Control Protocol/User Datagram Protocol , 以下简称 TCP/UDP )、 互联网协议( Internet Protocol, 以下简称 IP ) 、 GTPU, UDP、 IP等。 MEAS和 MEAS-SF在组网上可以连接, 例如, 可直接连接或通过 路由器(route )进行连接(图 1中所示为两种连接情况, 实际应用中, 可 择一使得 MEAS和 MEAS-SF相连) 。 图中虚线所示为现有的用户设备与 Internet 的网络通信路径, 为描述统一起见, 以下简称传统网络; 实线所 示为本发明中用户设备与 Internet的网络通信路径, 为描述统一起见, 以 下简称 MEAS 网络。 本发明实施例中, 多个 eNodeB对应一个 MEAS和 MEAS-SF。
用户设备向 eNodeB发起业务请求, 若该 eNodeB 和 MEAS 连接, 则 eNodeB可采用 MEAS网络将该业务请求发送给 MEAS, 业务请求表示用户 设备向 SP请求业务, 包括内容和应用服务等,如请求浏览视频、图片等内容; 或者, 请求登录邮箱、 登录银行账户等应用服务。 MEAS根据其上部署的内 容、 应用服务等业务, 判断是否可以向用户设备提供业务请求所请求的业务 数据并将业务请求发送至 MEAS-SF, 若可以提供, 则通过 eNodeB向用户设 备发送业务请求所请求的业务数据。 MEAS-SF将接收到的业务请求通过连接 的 P-GW发送给 SP, 并通过 P-GW接收 SP发送的业务请求所请求的业务数 据, 由于 P-GW上连接或集成了 BC、 LIG及 PCRF等功能模块, 即 P-GW与 BC、 LIG及 PCRF相连。 因此, P-GW可以在接收到上述业务请求后完成上 行过程中对用户设备的相关计费、监听及策略控制等操作,接收到 SP对上述 业务请求所请求的业务数据后完成下行过程中对用户设备的相关计费、 监听 及策略控制等操作, 即实现核心网侧对业务请求和业务请求所请求的业务数 据的计费。
若 MEAS根据承载的内容、 应用服务等业务, 判断出其不能够向用户设 备提供业务请求所请求的业务数据,则 MEAS还用于从 MEAS-SF获取 SP发 送的业务请求所请求的业务数据, 并将业务数据通过所连接的基站发送至用 户设备。
具体的, MEAS发送给 MEAS-SF的业务请求中还携带业务处理指示信 息, 业务处理指示信息用于指示 MEAS是否能够向用户设备提供业务请求所 请求的业务数据。 当 MEAS-SF接收到 MEAS发送的携带业务处理指示信息 的业务请求后, 解析出业务处理指示信息, 根据该业务处理指示信息, 判断 MEAS是否可以向用户设备提供业务请求所请求的业务数据, 若该业务处理 指示信息指示 MEAS能够向用户设备提供业务请求所请求的业务数据, 则丟 弃接收到的 SP发送的由 SP对业务请求所请求的业务数据, 启动协议栈信息 同步任务, 保证在 eNodeB发生切换后可以直接接收 SP发送的业务数据; 否 则, 若业务处理指示信息指示 MEAS不能够向用户设备提供业务请求所请求 的业务数据, 例如当 MEAS上未部署该业务请求所请求的业务数据的时候, 则 MEAS-SF将接收到的由 SP对业务请求所请求的业务数据发送至 MEAS。
上述实施例一中, MEAS在通过所连接的基站接收用户设备发送的业务 请求之前, 还通过所连接的基站接收用户设备发送的第一建链请求, 第一建 链请求用于请求用户设备和 SP 之间建立连接; 将第一建链请求发送给 MEAS-SF, 接收 MEAS-SF发送的 SP对第一建链请求的第一建链响应消息; 并通过所连接的基站向用户设备发送对第一建链请求的第一建链响应消息;
MEAS-SF还用于: 接收 MEAS发送的第一建链请求, 将第一建链请求 通过 P-GW发送给 SP; 通过 P-GW接收 SP对第一建链请求的第一建链响应 消息, 将第一响应消息发送给 MEAS。 请参照图 1 , 以用户设备 1为例, 用户设备 1向 eNodeB发送第一建链请 求, 例如: 建链 SYN ( synchronize) )报文, eNodeB收到 SYN报文后, 可以 通过传统网络发送给 SP, 或者采用本发明实施例提供的 MEAS 网络, 经由 MEAS发送给 SP; 若通过传统网络发送给 SP, 则后续流程与处理和原来的 传统网络一致, 在 MEAS-SF 处实现业务透传, 具体的, 请参照现有技术, 此处不再贅述。若采用 MEAS网络发送给 SP,则 MEAS接收 eNodeB发送的 SYN报文,记录 MEAS与各个网元直接或间接的交互的交互信息和建链过程 中的信息, 并将该 SYN ^艮文发送给 MEAS-SF, MEAS将该 SYN 文通过 传统网络经过 MEAS-SF和 P-GW发送给 SP。接着, SP回复建链响应消息给 用户设备 1 , 即 SP通过 MEAS-SF向 MEAS发送 SYN ACK, 以使 eNodeB 将 SYN ACK发送给用户设备 1 , 从而建立协议栈。 此过程中, MEAS记录 SP 到用户设备的协议栈信息, 例如, 同步号和序列号等, 具体为 SP 经过 P-GW、 MEAS-SF, MEAS, S-GW、 eNodeB等向用户设备的第一建链请求的 建链响应消息,如 SYN ACK等。然后,用户设备给 SP回复 ACK响应, MEAS 记录用户设备到 SP 的协议栈信息, 该协议栈信息具体为用户设备经过 eNodeB, MEAS, S-GW、 MEAS-SF, P-GW等向 SP的第一建链请求的建链 响应消息, 如 ACK等。 同理, MEAS-SF也需要记录协议栈交互的信息。 当 用户发起业务请求时, 若 MEAS和 MEAS-SF同时部署了传输层协议处理, 则 MEAS感知内容或应用服务, 对于每个业务请求需要完成协议栈的状态和 数据搬迁同步; 若 MEAS中不部署传输层协议处理, 只是部署了应用层的数 据, 则 MEAS感知内容或应用服务, MEAS和 MEAS-SF通过数据长度和偏 移进行传输以节省回程带宽, MEAS根据接收到的数据长度和偏移等镜像的 响应业务请求所请求的业务。
图 2为本发明业务提供系统实施例二的架构示意图, 本实施例适用于一 个 eNodeB可以对应一个 MEAS或 MEAS-SF的场景。 本实施例的实现方 式与实施例一的实现方式类似, 具体原理请参照图 1 , 此处不再贅述。 另外, 本实施例中, MEAS在通过所连接的基站接收用户设备发送的业务请求之前, 还通过所连接的基站接收用户设备发送的第二建链请求, 第二建链请求用于 请求用户设备和 SP之间建立连接;通过所连接的基站向用户设备发送对第二 建链请求的第二建链响应消息; MEAS发送给 MEAS-SF的业务请求中还携 带 MEAS和用户设备之间的连接信息;
MEAS-SF还用于: 接收 MEAS发送的携带 MEAS和用户设备之间的连 接信息的业务请求, 根据连接信息, 通过 P-GW向 SP发送第三建链请求, 并 通过 P-GW接收 SP对第三建链请求的第三建链响应消息。
请参照图 2 , 以用户设备 2为例, 用户设备 2向 eNodeB发送第二建链请 求, eNodeB收到 SYN报文后,按照分流原则, 采用传统网络或 MEAS网络, 若采用传统网络, 则后续流程与处理和原来的传统网络一致, 在 MEAS-SF 处实现业务透传, 具体的, 请参照现有技术, 此处不再贅述。 若采用 MEAS 网络, 则 MEAS接收 eNodeB发送的 SYN报文, 代替 SP和用户设备 2建立 连接。 接着, MEAS通过 eNodeB向用户设备 2发送 SYN ACK, 用户设备 2 通过 eNodeB给 MEAS返回对第二建链请求的第二建链响应消息, 如 ACK:。 亦即,用户设备和 MEAS通过 3次握手,建立用户设备和 MEAS之间的连接。 用户设备 2发起业务请求时, MEAS将用户设备与 MEAS已建立连接的连接 信息携带在业务请求中发送给 MEAS-SF, 当 MEAS-SF解析出该指示仅建立 了用户设备到 MEAS 之间的连接的建链信息后, 根据所述连接信息, 通过 P-GW向 SP发送第三建链请求, 并通过 P-GW接收所述 SP对第三建链请求 的第三建链响应消息, 从而建立 MEAS-SF和 SP之间的连接。
需要说明的是, 上述实施例一中, 用户设备通过发送第一建链请求使得 该用户设备直接 SP之间建立连接; 实施例二中, 用户设备与 SP之间间接的 建立连接, 即用户设备先与 MEAS建立连接, 再将携带用户设备与 MEAS建 立连接的连接信息发送至 MEAS-SF, MEAS-SF解析出连接信息后和 SP建立 连接, 从而完成用户设备到 SP之间的连接。 然而, 本发明并不以此为限制, 在其他可能的实施方式中,实施例一中也用户设备也可以间接的和 SP建立连 接, 实施例二中用户设备也可以直接和 SP建立连接。
图 3为本发明业务提供方法实施例一的流程图。 同时参见图 1 , 本实 施例的执行主体为 MEAS , 本实施例以多个 eNodeB对应一个 MEAS和 MEAS-SF的场景为例进行说明。 具体的, 本实施例可以包括以下步骤:
101 : 移动边缘应用服务器 MEAS通过所连接的基站接收用户设备发送 的业务请求并将业务请求发送至移动边缘应用服务器支持节点 MEAS-SF,业 务请求表示用户设备向服务提供商 SP请求业务, MEAS部署在接入网侧, 与 一个或多个基站连接, 并与移动边缘应用服务器支持节点 MEAS-SF连接。 具体的, 用户设备可以向 eNodeB发起的业务请求, eNodeB可以将该业 务请求发送给 MEAS, 业务请求表示用户设备向 SP请求业务。业务请求包括 内容和应用服务, 如请求浏览视频、 图片等内容; 或者, 请求登录邮箱、 登 录银行账户等应用服务。
MEAS将接收到的业务请求发送给 MEAS-SF, 以使得 MEAS-SF将该业 务请求发送给 SP。 此过程中, 由于 MEAS-SF与 P-GW相连, MEAS-SF可以 通过 P-GW将业务请求发送给 SP。 又由于 P-GW 与计费中心 (Charging Center, 以下简称 BC ) 、 法律监听网关( Lawful Interception Gateway, 以下 简称 LIG )及策略控制中心 ( Policy And Charging Rules Function, 以下简称 PCRF )相连, 因此, P-GW可以在接收到上述业务请求后对用户设备进行相 关计费、 监听及策略控制等操作。
102: 若 MEAS能够向用户设备提供业务请求所请求的业务, 则通过所 连接的基站向用户设备发送业务请求所请求的业务数据。
本步骤中, 因 MEAS上部署了 SP提供内容、 应用服务等业务, MEAS 可以判断本地是否可以对用户设备提供业务请求所请求的业务数据,若可以, 则 MEAS根据接收到的业务请求向用户设备发送该业务请求所请求的业务数 据; 若 MEAS不能够向用户设备提供业务请求所请求的业务数据, 则 MEAS 可以等待 MEAS-SF发送的 SP对该业务请求所请求的业务数据。 具体的, 用 户设备发起的业务请求, 经过 eNodeB发送到 MEAS, MEAS接收该业务请 求并判断是否能够向用户设备提供业务请求所请求的业务数据, 并将该业务 请求发送给 MEAS-SF, MEAS-SF再将该业务请求发送给 SP, 由 SP生成该 业务请求所请求的业务数据并将业务数据发送给 MEAS-SF。 当 MEAS-SF判 断出 MEAS可以处理该业务请求时, 则丟弃 SP发送的对该业务请求所请求 的业务数据; 否则, 若 MEAS-SF判断出 MEAS不能够向用户设备提供业务 请求所请求的业务数据时,则将 SP发送的对该业务请求所请求的业务数据发 送给 MEAS, 使得 MEAS进一步的将业务数据发送给用户设备, 从而为用户 设备提供业务。 其中, 业务数据中携带业务请求所请求的业务, 例如, 允许 用户设备浏览视频、 图片等内容; 或者, 为用户设备提供登录邮箱、 登录银 行账户等应用服务。 本实施例提供的业务提供方法, MEAS通过所连接的基站接收用户设备 发送的表示用户设备向 SP 请求业务的业务请求, 并将业务请求发送给 MEAS-SF, MEAS-SF进一步的将业务请求发送给 SP, MEAS通过基站用户 设备发送本地生产的业务请求所请求的业务数据或接收到的 SP发送的对该 业务请求所请求的业务数据, 从而为用户设备提供业务。 本实施例提供的业 务提供方法, MEAS上部署了 SP提供内容、 应用服务等业务, 当 MEAS能 够向用户设备提供业务请求所请求的业务时, 直接从本地对业务请求生成业 务请求所请求的业务数据并为用户设备提供业务, 由于 MEAS 在物理部署 上往往靠近 eNodeB, 即部署在 RAN侧, 使得用户设备无需通过 RAN和 CN从服务器或 Internet上获取 SP提供的业务, 而直接从 RAN侧获取所需业 务, 避免了 RAN和 CN之间数据拥塞、 节省网络资源。
在上述实施例一的基础上, 可选的, MEAS发送给 MEAS-SF的业务请 求中还携带业务处理指示信息, 业务处理指示信息用于指示 MEAS是否能够 向用户设备提供业务请求所请求的业务数据。
具体的,当 MEAS接收到用户设备发起的经 eNodeB透传的业务请求后, 根据部署的 SP提供的内容、 应用服务等业务, 判断是否可以处理该业务请 求, 即是否可以对该业务请求生成对应的业务数据。 若 MEAS能够向用户设 备提供该业务请求所请求的业务数据, 则为该业务请求设置 MEAS能够向用 户设备提供业务请求所请求的业务数据的业务处理指示信息;否则,若 MEAS 不能够为用户设备提供业务请求所请求的业务数据, 则为该业务请求设置 MEAS 不能够处理该业务请求的业务处理指示信息, 并将业务处理指示信息 携带在业务请求中发送给 MEAS-SF。
在前述实施例的基础上, 作为一种可行的实施方式, MEAS在通过所 连接的基站接收用户设备发送的业务请求之前, 还通过所连接的基站接收用 户设备发送的第一建链请求,第一建链请求用于请求用户设备和 SP之间建立 连接, 将第一建链请求发送给 MEAS-SF, 以使 MEAS-SF将第一建链请求发 送给 SP; MEAS接收 MEAS-SF发送的 SP对第一建链请求的第一建链响应 消息; MEAS通过所连接的基站向用户设备发送对第一建链请求的第一建链 响应消息。

MEAS-SF将接收到的业务请求通过 P-GW发送给 SP, 由于 P-GW上连 接或集成了 BC、 LIG及 PCRF等功能模块, 即 P-GW与 BC、 LIG及 PCRF 相连。 因此, P-GW可以在接收到上述业务请求后完成上行过程中对用户设 备的相关计费、 监听及策略控制等操作。
203: MEAS-SF通过 P-GW接收 SP发送的对业务请求所请求的业务数据, 以便核心网侧对业务请求和业务请求所请求的业务数据进行计费。 具体的, 用户设备发起的所有业务请求都经过 eNodeB发送到 MEAS, MEAS将接收到的所有业务请求发送给 MEAS-SF ,再由 MEAS-SF通过 P-GW 将接收到的所有业务请求发送给 SP, 使得 SP对接收到的所有业务请求生成 业务请求所请求的业务数据并通过 P-GW发送至 MEAS-SF,完成下行过程中 核心网侧对业务请求所请求的业务数据的计费等动作。

704、 UE发起业务请求, 经过 eNodeB流到 MEAS, MEAS进行业务判 断, 判断其能否向用户设备提供业务请求所请求的业务数据, 若可以提供, 则在业务请求中设置 MEAS能够处理该业务请求的业务处理指示信息,否则, 在业务请求中设置 MeAS不能够处理该业务请求的业务处理指示信息, 并将 业务处理指示信息以及表明 UE和 MEAS之间已建立连接的连接信息携带在 业务请求中发送给 MEAS-SF;
705、 MEAS-SF收到携带业务处理指示信息以及表明 UE和 MEAS之间 已建立连接的连接信息的业务请求后, 进行解析, 解析出业务处理指示信息 及连接信息, 并根据该解析出的业务处理指示信息, 记录 MEAS是否可向用 户设备提供该业务请求所请求的业务数据, 即记录 MEAS对业务请求所请求 的业务的提供能力; 并且, 根据解析出的连接信息, 发现仅建立了用户设备 和 MEAS之间的连接后,则通过 P-GW向 SP发送第三建链请求,如建链 SYN 报文, 并通过 P-GW接收 SP对所述第三建链请求的第三建链响应消息, 如 SYN ACK, 从而建立 MEAS-SF与 SP之间的连接。 然后, MEAS-SF基于建 立的 MEAS-SF与 SP之间的连接, 将业务请求经 P-GW发送给 SP。 此过程 中, P-GW完成上行过程中对用户设备的相关计费、 监听及策略控制等操作;
706、 根据 704中 MEAS对接收到的业务请求的判断, MEAS对接收到 的业务请求做相应的处理。 具体的, 若 MEAS判断出其可以向用户设备提供 业务请求所请求的业务数据, 则在本地对业务请求生成对应的业务数据 ( Data ) ; 否则, 若 MEAS判断出其不能够向用户设备提供业务请求所请求 的业务, 则等待 SP过来的响应;
707、 SP收到 MEAS-SF经 P-GW发送的业务请求后,生成与业务请求对 应的业务数据 ( Data )并经 P-GW发送给 MEAS-SF。 此过程中, P-GW完成 下行过程中对用户设备的相关计费、 监听及策略控制等操作;
708、 MEAS-SF根据记录的 MEAS对业务请求所请求的业务的提供能力, 判断 MEAS 是否能够向用户设备提供业务请求所请求的业务数据。 若 MEAS-SF判断出 MEAS能够向用户设备提供业务请求所请求的业务, 则丟 弃 SP发送的对业务请求的业务数据( Data ),同时发送速率控制信息给 MEAS, 使得 MEAS与 MEAS-SF之间的速率同步;否则,若 MEAS-SF判断出 MEAS 不能向用户设备提供业务请求所请求的业务数据, 且由于此时通过建链 SYN 报文建立的连接为 UE 与 MEAS之间、 MEAS-SF 与 SP之间, MEAS 与 MEAS-SF之间未建立连接, 需要对业务数据重新进场封装, 即 MEAS-SF通 过带外接口将 SP发送的对业务请求的业务数据重新组装后转发给 MEAS;
709、 根据 MEAS的业务的提供能力, MEAS接收到的信息是不同的。 具体的, 本步骤可以包括下列子步骤:
709.1、 若 MEAS接收到的是 MEAS-SF发送的数据长度和偏移信息等数 据描述信息并进行解析, 若解析得到速率控制信息, 则同步与 MEAS-SF之 间的速率;
709.2、 若 MEAS接收到的是 MEAS-SF重新组装后的业务请求所请求的 业务数据, 则解析出相应的内容并发送给用户设备;
710、 UE将本地生成的业务数据以及解析出的由 MEAS-SF重新组装后 的业务请求的业务数据通过 eNodeB转发给 UE以向 UE提供内容、应用服务 等业务;
71 1、 UE回复 ACK给 MEAS , MEAS-SF回复 ACK给 SP;
需要说明的是, 用户设备发起的业务请求, 所请求的内容、 应用服务请 业务可能比较大, 需要 MEAS或 SP分多次将根据该业务请求生成对应的业 务数据发送给用户设备, 也就是说, 对同一业务请求生成的业务数据可能有 多个。 此时, 循环执行 706〜71 1 , 具体如图中黑色虚线框所示, 直到所有的 业务数据发送结束;
712、 当 UE发起的业务请求所所请求的业务数据发送完毕后, UE向 SP 发送重置指令(Reset, 简称 RST )或终止指令(Final, 以下简称 FIN ) (图 中未示出)等拆链消息, 拆除 UE与 SP之间通过 eNodeB、 MEAS , S-GW、 MEAS-SF, P-GW等建立的连接, 亦即, MEAS接收到拆链消息后,拆除 UE、 eNodeB与 MeAS之间的连接, SP收到拆链消息后, 拆除 MEAS-SF、 P-GW 与 SP之间的连接。
图 Ί实施例中, 最初建立的 UE和 MEAS之间的连接, 且每个 eNodeB 有一个 MEAS或者 MEAS-SF与之对应, 通信网络中存在多个 MEAS及 MEAS-SF , 而图 5、 图 6实施例中建立的是 UE和 SP之间的连接, 且通信网 络中仅存在一个 MEAS及 MEAS-SF , MEAS可以启动协议栈信息同步任务, 保证业务在 eNodeB切换后可以直接接受 SP的数据。 图 7实施例中, MEAS 为连接终结点, 或者也可以称之为协议描点, 因此, 当发生 eNodeB切换时, 可以根据建网规则中 MEAS之间的映射关系,切换 MEAS ,进而切换 eNodeB。 具体的, 可参照图 8。
图 8为本发明业务提供方法实施例六的信令图。 本实施例适用于通信网 络中存在多个 MEAS及 MEAS-SF且发生 eNodeB切换的场景。以下结合图 3 及图 8, 对本发明实施例提供的业务提供方法进行详细说明。
801、 根据移动建网规则, 建立 MEAS的映射关系。 具体的, 本步骤中, 建立了 MEAS1与 MEAS2之间的映射关系;
802、 UE从 eNodeBl接入移动通信网络, 并且和 MEAS1完成 3次握手 如, UE与 MEAS之间发送 SYN、 SYN ACK以及 ACK等, 已建立 UE与 MEAS1之间的连接, 由 MEAS1为 UE提供业务, 即由 MEAS1直接将对业 务请求生成对应的业务数据 ( Data )发送给 UE;
803、 当 UE从 eNodeBl切换到 eNodeB2上时, UE向 MEAS2发起 ACK 响应 , MEAS2向源 eNodeBl及 MEAS1查询业务请求被代理的情况。具体的 , 若接收到的业务请求为 SYN报文, 说明是非历史业务, 直接由 MEAS2判断 其能否向用户设备提供业务请求所请求的业务; 否则, 若接收到的业务请求 不是 SYN报文, 则由 MEAS1判断其能否向用户设备提供业务请求所请求的 业务, 若 MEAS1不能够提供, 则采用传统网络将业务请求发送至 SP。
804、 若 MEAS2向源 eNodeB 1及 MEAS 1查询到业务请求是被代理的 , 则建立全新的隧道, 将 MEAS 1对请求生成对应的业务数据(Data )从该隧道 经 eNodeB2转发到 MEAS2,再由 MEAS2将其发送至 P-GW完成计费监听(图 中未示出)等再经由 eNodeB2发送至用户设备, 不断循环的进行数据转发, 直到连接全部断掉; 若 MEAS2向源 eNodeBl及 MEAS1查询到业务请求没 有被代理, 则将业务请求发送给 SP。
需要说明的是, 上述图 1及图 2所示业务提供系统的架构示意图, 在现 有技术的基础上仅增加了 MEAS及 MEAS-SF, 然而, 本发明并不以此为限 制, 在其他可行的实施方式中,还可以增加移动边缘应用服务器中心( MEAS center ) , 由 MEAS Center管理各个 MEAS, MEAS Center和 MEAS构成分 层服务处理。
还需要说明的是, 上述各个实施例均是以将 MEAS 在物理部署上靠近 eNodeB 为例对本发明进行详细阐述, 然而, 本发明并不以此为限制, 在 其他可能的实施方式中, MEAS也可以集成在 eNodeB等基站上。以 UMTS 网络为例, 当 MEAS靠近 NodeB部署或集成在 NodeB上时, RAN内部, 即 NodeB和无线网络控制器 ( Radio Network Controller, 以下简称 RNC ) 之间的带宽资源可以得到节省。
