Description

基站、 服务处理方法和云计算系统 本申请要求于 2011 年 10 月 21 日提交中国专利局、 申请号为 201110323739.2, 发明名称为 "基站、 月良务处理方法和云计算系统 "， 上述专 利的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领域， 并且更具体地， 涉及基站、 服务处理 方法和云计算系统。 背景技术
基于传统移动通信系统的移动互联网络由无线接入网 （RAN , Radio Access Network )和移动核心网 （ CN, Core Network )组成。 RAN负责为用户 设备 ( UE , User Equipment )提供无线接入， CN则通过移动性管理为用户设 备提供固定的互联网协议（ IP , Internet Protocol )接入点。 这样， 用户设备通 过移动通信网络接入到外部 IP网络，并通过外部 IP网络访问应用服务器（ AS, Application Server )„ 用户设备通常提供客户端 （Client )功能， 应用服务器的 应用则由应用提供商提供。
从应用提供商 （ISP, Internet Service Provider ) 的角度来看， 大量的中小 型 ISP还是采用服务器托管和带宽租用等方式对外提供应用服务， 其中， 或者 是 ISP直接租用服务器和网络带宽，或者是 ISP自己购买服务器及其配套软件， 再租用网络带宽对外提供应用服务。
从终端用户的角度来看， 移动互联网应用除了需要管道的接入服务外， 还大量需要存储服务和计算服务， 其中存储服务是指保存用户的数据， 包括图 片、 视频、 数据文件、 电子邮件等格式化数据， 计算服务是指提供办公类软件
(如字处理软件）、 CAD/CAM/CAE等软件、 网络游戏等。 目前， 用户特定的 存储服务和计算服务主要由用户设备自身提供，但明显受限于手机等用户设备 非常有限的计算和存储能力。
基于传统移动通信系统的移动互联网的一个主要问题在于， 移动通信系 统被完全管道化， 即仅仅提供一个 IP接入的通道， 而不能直接从应用服务器 获取应用相关的信息， 如应用的业务属性（业务类型、 最大速率、 平均速率等
QoS ( Quality of Service, 业务质量）信息）、 业务的信源编码信息 （如视频流 业务等）等。 这样， 应用与管道分离， 基站等 RAN网元只提供接入层功能， 应用层和传输层 ( TCP/UDP , Transmission Control Protocol/ User Datagram Protocol, 传输控制协议 /用户数据包协议） 与接入层的跨层优化很难实施。 发明内容
本发明实施例提供一种基站、 服务处理方法和云计算系统， 能够提升系 统性能。
一方面， 提供了一种基站， 包括： 无线网络功能模块， 用于与 UE之间建 立无线网络承载通道； 接收模块， 用于通过无线网络承载通道接收 UE的服务 请求； 第一处理模块， 用于解析 UE的服务请求中的请求内容， 根据请求内容 中需要由云服务器端处理的内容生成云服务访问请求，发送云服务访问请求到 云服务器端， 并将云服务器端的相应处理结果通过无线网络承载通道返回给 UE。
另一方面， 提供了一种服务处理方法， 包括： 与 UE之间建立无线网络承 载通道； 通过无线网络承载通道接收 UE的服务请求； 解析 UE的服务请求中 的请求内容，根据请求内容中需要由云服务器端处理的内容生成云服务访问请 求； 发送云服务访问请求到所述云服务器端， 并将云服务器端的相应处理结果 通过无线网络承载通道返回给 UE。
另一方面， 提供了一种云计算系统， 包括多个云服务器端， 多个云服务 器端之间相互连接， 每个云服务器端与一个或多个如上所述的基站连接。
本发明实施例的基站与用户设备之间建立无线网络承载通道， 从而终结 了用户设备的接入层协议。 另外， 从传输层协议的层面来看， 本发明实施例的 基站不是筒单地转发用户设备的服务请求， 而是解析服务请求中的请求内容， 并根据请求内容自己进行处理或针对需要云服务器端处理的内容请求云服务 器端协助进行处理，从而由基站终结了该用户设备的传输层协议。这样使得用 户设备侧的传输层协议和接入层协议均终结于基站，因此本发明实施例能够实 现传输层和接入层的跨层优化。 附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例或现有技术 描述中所需要使用的附图作筒单地介绍，显而易见地， 下面描述中的附图仅仅 是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动 的前提下， 还可以根据这些附图获得其他的附图。

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作出创造性 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。
用户特定的存储服务和计算服务主要由用户设备自身提供， 但明显受限 于手机等用户设备非常有限的计算和存储能力。现在也开始出现通过云计算方 式提供此类服务的趋势。
云计算是共享的网络交付信息服务的业务运行模式。 云形象地描绘了包 括网络、 计算和存储等在内的信息服务的基础设施， 以及相关的操作系统、 应 用平台、 Web (网络）服务和应用等软件的总和。 在云计算中， 系统的软硬件 都被虚拟化并封装为服务， 用户设备可以通过网络访问和使用， 云服务的使用 者看到的只有服务本身，而不用关心相关基础设施的具体实现，包括地址位置、 资源分配和管理、 软硬件平台等等。 云计算的硬件基础设施典型是数据中心 ( Data Center ), 或者互联的多个数据中心， 或者是分布在不同地理位置的计 算机组成的服务器集群等。云计算的软件基础设施则负责硬件基础设施的虚拟 化、 资源的管理与监控、 安全与计费管理等， 从而将软硬件基础设施封装为服 务提供给用户。
图 1是基于本发明实施例的云计算系统 10的示意结构图。 图 1中， 云服 务器端（或者称为 "中心云"） 11典型地运行在高性能数据中心或多个互联的 数据中心之上。 eNB+ 12a、 12b、 12c是根据本发明实施例的增强型基站， 完 成针对用户设备 13a、 13b、 13c所有无线网络的功能， 包括接入层和非接入层 功能。 eNB+与云服务器端 11通过高速宽带 IP ( Internet Protocol, 互联网协议） 线路相连（统称为接口 Z )。 eNB+ 12a、 12b、 12c之间的逻辑接口为 X2+, 用 于支持跨 eNB+的移动性管理。
图 1 中所示各种网元的数目只是示例性的， 不对本发明实施例的范围构 成限制。 例如， 云计算系统 10可包括一个或多个云服务器端 11 , 每个云服务 器端可连接一个或多个 eNB+, 每个 eNB+可以月良务一个或多个 UE。
图 2是本发明一个实施例的基站的框图。 图 的基站 20是图 1的 eNB+ 的一个例子， 包括接收模块 21、 第一处理模块 22和无线网络功能模块 24。
无线网络功能模块 24与 UE (例如， 图 1的用户设备 13a、 13b、 13c )之 间建立无线网络承载通道。 这样， 基站 20能够终结 UE的接入层协议。
接收模块 21通过无线网络承载通道接收 UE服务请求。 例如， 接收模块 21可以实现为基站 20上的天线等。
第一处理模块 22解析 UE的服务请求中的请求内容， 根据所述请求内容 中需要由云服务器端处理的内容生成云服务访问请求，发送云服务访问请求到 云服务器端（例如图 1的云服务端 11 ), 并将云服务器端的相应处理结果通过 无线网络承载通道返回给 UE。 例如， 第一处理模块 22可以实现为基站 20上 的基带处理单元等。
在解析得到请求内容之后， 基站自己决定如何进行处理。 例如， 对于基 站自己能够处理的内容， 如跨层优化、联合编码处理、数据压缩 /汇¾ /緩存等， 则可以由基站执行这些处理。 对于需要云服务器处理的内容， 如数据存储 /计 算等， 则基站可向相应的云服务器端发送云服务访问请求， 以请求云服务器端 进行相应的处理。 这样， 从用户设备的角度来看， 犹如应用服务器就处于基站 中。用户设备直接向基站进行服务请求， 即由基站终结了该用户设备的传输层 协议。 而现有技术中， 用户设备向应用服务器进行服务请求， 基站不会解析服 务请求中的请求内容， 只是根据服务请求的目的地址等信息（这些信息一般在 服务请求包的包头中 ), 筒单地查找路由并转发该服务请求。
综上所述， 本发明实施例的基站与用户设备之间建立无线网络承载通道， 从而终结了用户设备的接入层协议。 另外， 从传输层协议的层面来看， 本发明 实施例的基站不是筒单地转发用户设备的服务请求，而是解析服务请求中的请 求内容， 并根据请求内容自己进行处理或请求云服务器端协助进行处理，使得 用户设备侧的传输层协议和接入层协议均终结于基站，因此本发明实施例能够 实现传输层和接入层的跨层优化。
图 3是本发明另一实施例的基站的框图。 图 3的基站 30是图 1的 eNB+ 的一个例子， 与图 2的基站 20的不同之处在于， 除了无线网络功能模块 24、 接收模块 21和第一处理模块 22之外， 还包括第二处理模块 23、 第三处理模 块 25和移动性管理模块 26中的至少一个。
第二处理模块 23与云服务器连接， 通过云计算方式， 从云服务器端获得 无线网络承载通道的功能控制服务。例如， 上述无线网络承载通道的功能控制 服务可包括： 定位服务， 如位置计算等； 用户签约数据存储和查询， 包括 HLR ( Home Location Register, 归属位置寄存器 ) /HSS ( Home Subscriber Server, 归属用户月良务器）、 AAA ( Authentication, Authorization, Accounting, 验证、 授权和记账）服务器等的功能、 策略控制与计费功能等。
无线网络功能模块 24与第一处理模块 22和第二处理模块 23连接， 通过 实现现有的无线网络的接入层协议和非接入层协议， 与 UE之间建立一个或多 个无线网络承载通道。 无线接入层典型地功能包括物理层 （PHY, Physical Layer )、 媒体接入控制层（ MAC, Media Access Control )、 无线链路层 ( RLC, Radio Link Control ), 以及分组数据汇聚层（ PDCP, Packet Data Convergence Protocol )等协议功能， 用于通过空口传输用户 IP数据分组。 无线非接入层功 能典型地包括 L3协议和分组数据网关（ PDN-GW或 PGW, Packet Data Network Gateway ) 功能， 其中 L3协议与用户设备 UE侧的 L3协议相对应， 用于控制 无线接入承载的建立、 修改和删除等操作， 分组数据网关提供 IP网关功能， 如 IP地址分配、 网络地址转换（NAT, Network Address Transform ), 用户数 据的监管控制 （Policing Control )等功能， 这样， 无线非接入层之上的接口为 IP接口。 因此， 无线网络功能模块 24可以与第一处理模块 22之间交换应用 相关的信息；无线网络功能模块 24可以与第二处理模块 23之间交换无线网络 控制相关的信息。
作为一个可选的实施例， 第一处理模块 22可以获取服务请求所针对的业 务的应用属性信息和 /或信源编码信息等应用相关的信息。例如，在 UE的服务 请求可携带有该服务请求所针对的业务的应用属性信息和 /或信源编码信息的 情况下， 第一处理模块 22可以在解析 UE的服务请求中的请求内容时， 获取 这些应用相关的信息。 或者， 第一处理模块 22也可以从其他源 （例如， 与应 用相应的云服务器端或云服务实体）获取应用相关的信息， 本发明实施例对此 不作限制。无线网络功能模块 24可以从第一处理模块 22获取应用属性信息和 /或信源编码信息， 并利用应用属性信息和 /或信源编码信息实现 QoS保证。
另一方面， 无线网络功能模块 24可以获得无线网络承载通道上的无线链 路和 /或无线资源的实时状态信息等应用相关的信息。 无线网络功能模块 24可 以按照任何现有方式获取无线链路和 /或无线资源的实时状态信息， 本发明对 此不作限制。第一处理模块 22也可以从无线网络功能模块 24获得无线链路和 /或无线资源的实时状态信息，并根据无线链路和 /或无线资源的实时状态信息， 完成传输层与接入层的跨层联合优化。
此外， 无线网络功能模块 24在与 UE之间建立无线网络承载通道时， 也 可以参考上述应用相关的信息。
这样， 由于 UE侧的传输层协议和接入层协议均在基站 30中终结， 因此 基站 30能够实现传输层与接入层的跨层联合优化。
作为另一可选的实施例，第一处理模块 22还可将无线链路和 /或无线资源 的实时状态信息提供给第三方应用， 以便第三方应用利用无线链路和 /或无线 资源的实时状态信息进行跨层优化。第三方应用可以是运行在运营商提供的数 据中心及相应的软件平台上的应用，也可以是来自其它运营商的数据中心及相 应的软件平台上的应用，或者是一些大型公司的数据中心及相应的软件平台上 的应用， 本发明对此不做限制。
第三处理模块 25为 UE上的云计算应用提供代理服务。 具体地， 第三处 理模块 25可汇聚、 压缩或緩存 UE与对应云服务实体之间的数据； 在接收到 UE向该云服务实体发送的针对该数据的请求时， 向 UE发送该数据， 并终止 向该云服务实体转发该请求。 例如， 第三处理模块 25专门针对 UE上的某些 云计算应用。 在这类云计算应用中， UE本地的存储服务和计算服务， 如用户 私人数据， 包括图片、 视频、 数据文件、 电子邮件等格式化数据的存储， 以及 本地大型应用软件， 如办公类软件、 CAD/CAM/CAE等软件、 网络游戏等， 可能采用云计算方式来提供。 典型地可以采用 SaaS ( Software as a Server, 软 件即服务）、 PaaS ( Platform as a Server, 平台即服务）等形式。 这时， 集成在 基站 30中的第三处理模块 25起到代理服务器的功能， 包括终结 UE侧云租户 端的传输层协议（TCP/UDP ), 实现传输控制协议层与无线接入层的跨层联合 优化，或者用于汇聚、压缩和 /或緩存 UE上的所述云租户端与对应云服务实体 之间的数据。
作为另一可选的实施例， 移动性管理模块 26在 UE发生跨基站的无线接 入层切换和 /或无线非接入层迁移时， 在当前基站的第一处理模块（假设标记 为 22a ) 为 UE服务的同时， 在目标基站的第一处理模块（假设标记为 22b ) 中启动第一处理模块 22a的拷贝，将第一处理模块 22a和第一处理模块 22b同 步到云服务器端中的相应的应用。 如果 UE在当前基站的通信涉及其他模块， 如第二处理模块 23、 无线网络功能模块 24、 第三处理模块 25等， 也类似地进 行切换或迁移操作。
现有移动通信网络中应用与管道分离， 基站等 RAN网元只提供接入层功 能， 应用层和传输层（TCP/UDP )与接入层的跨层优化很难实施， 也无法对业 务提供有效的 QoS保证。 另外， 基于传统移动通信系统的移动互联网架构， 使得移动运营商只能提供管道的接入服务， 从而限制了移动运营商的业务范 围， 使移动运营商在整个产业价值链中处于较低端的位置。
本发明实施例的基站 30完成了接入层、 非接入层功能， 并且终结 UE侧 应用的传输层协议， 实现管道和云的有机结合， 一方面便于跨层优化技术和 QoS管理的实施， 另一方面也拓展了移动运营商的业务范围，使移动运营商不 但能提供管道服务， 还可以提供存储、 计算等信息服务。
例如， 当用户设备请求视频服务时， 基站 30可解析视频服务的请求， 得 到相关的请求内容信息， 如视频标识、 要求的分辨率等信息。 基站 30可向存 储该视频的云服务器请求传输该视频。当接收到的视频的分辨率不符合上述要 求的分辨率时， 基站 30还可以请求能够处理该视频的云服务器对该视频进行 处理， 以符合用户设备要求的分辨率。 然后， 基站 30将处理后的视频返回给 用户设备。 上述处理均由基站 30进行控制， 因此便于跨层优化技术和 QoS管 理的实施。 但是应注意， 上述例子仅仅描述了实施本发明的一种可能的方式， 而不是限制性的；按照基站 30和云服务端之间的云服务网络架构或交互机制， 可相应地调整基站 30自己能够处理的内容和处理方式。
下面结合具体例子， 更加详细地描述本发明的实施例。
图 4是说明本发明一个实施例的基站的内部功能结构的示意结构图。图 4 的基站 40是图 1的 eNB+的一个例子， 并且是基站 20和 30的一个具体实现 形式。
如图 4所示， 基站 40的无线网络功能模块 44是图 3的无线网络功能模 块 24的一个例子， 包括无线接入层单元 441和无线非接入层单元 442。
无线接入层单元 441的功能典型地包括 PHY、 MAC, RLC以及 PDCP等 协议功能， 用于通过空口传输用户 IP数据分组。 无线非接入层单元 442的功 能典型地包括 L3协议和 PGW功能， 其中 L3协议与用户设备 UE侧的 L3协 议相对应， 用于控制无线接入承载的建立、 修改和删除等操作。 PGW提供 IP 网关功能， 如 IP地址分配、 网络地址转换（NAT )、 用户数据的监管控制等功 能。 这样， 无线非接入层单元 442之上的接口为 IP接口。
如图 4所示， 无线非接入层单元 442之上包含 3个功能实体， 即应用服 务器云租户 ASCT ( Application Server Cloud Tenant ), 无线网络功能云租户 WNFCT ( Wireless Network Function Cloud Tenant ) 和终端应用云租户代理 TACTP ( Terminal Application Cloud Tenant Proxy ), 分别作为图 3的第一处理 模块 22、 第二处理模块 23和第三处理模块 25的实例。
WNFCT、 ASCT和 TACTP与云服务器端 （中心云） 的接口分别为 Zl、 Z2和 Z3。 其中， WNFCT通过云计算方式， 从中心云获得无线网络功能相关 的服务，如定位服务（位置计算等）、用户签约数据存储和查询（包括 HLR/HSS、 AAA服务器等的功能）、 策略控制与计费功能等。 在现有技术中， 这些功能都 是由特定的网元完成的，而在本发明实施例中，这些功能都采用云计算的方式， 由数据中心通过虚拟服务器（Virtual Server )等形式完成。 集成在基站 40中 的是这些功能的云端， 基站 40通过 WNFCT从中心云获得上述无线网络功能 相关控制服务。
ASCT的功能可包括采用云计算的方式， 通过集成在基站 40中的应用服 务器的云端， 由数据中心通过虚拟服务器等形式提供应用服务器 （AS , Application Server )的功能。这样， UE侧的移动宽带应用的 Client端（客户端 ) 的传输层（TCP/UDP ), 终结在基站 40中的 ASCT功能实体。 从 UE看来， 应 用服务器就处于基站 40中。 由于 ASCT功能集成在基站 40中， 因此， 基站 40中的无线网络功能模块 44可以通过与 ASCT的内部接口， 获取应用相关的 信息， 如业务的应用属性（业务类型、 最大速率、 平均速率等 QoS信息）、 业 务的信源编码信息（如视频流业务等）等， 从而对业务提供有效的 QoS保证。 同时， 由于 ASCT终结了 UE侧移动宽带应用 Client端的传输层协议， 并且可 以从基站 40中的无线网络功能模块 44获得实时的无线链路和无线资源的状态 信息（如无线链路的编码调制信息、 无线信道条件、 空口负载状态等）， 因此， 基站 40可以实施传输层（TCP/UDP ) 与无线接入层的跨层联合优化， 充分利 用无线资源， 最大化系统吞吐量。 关于传输层（TCP/UDP )与无线接入层的跨 层联合优化， 可以参考大量的现有技术， 如张海霞等编著的《无线通信跨层设 计——从原理到应用》（ ISBN 978-7-115-22781-2 )。
另夕卜， ASCT还能利用从基站 40中的无线网络功能模块 44获得无线网络 承载通道的无线链路和无线资源的实时状态信息，对包含视频、 图像等媒体的 业务， 实施信道信源的联合编码， 即根据实时的无线链路状态信息（如信号与 干扰 /噪声功率比 SINR ), 基于系统吞吐量最大和保证用户体验不变的原则， 联合选择最优的视频、 图像等媒体的编码方式和编码速率、无线链路的信道编 码方式和调制方式等。相比之下，现有技术中无线链路的信道编码调制方式的 选择和视频、 图像等媒体的编码方式与速率的选择是完全独立的， 不能有效利 用空口资源实现系统容量的最大化。 关于无线网络中信道信源的联合编码技 术， 具体可以参考大量的现有技术， 如 0. Oyman and J. Foerster, Distortion- Aware MIMO Link Adaptation for Enhanced Multimedia Communications, WiMAGIC-Huawei Workshop, Towards IMT-A and Beyond, PIMRC 2010。
可见， WNFCT和 ASCT功能是通过云计算的方式， 将现有技术中位于无 线网络中的部分数据存储（如签约用户业务订购信息、 用户帐号信息、 用户位 置信息等） 和计算功能 （如数据库搜索和查询、 数据加密等）， 如原来的
HLR/HSS、 策略与计费规则功能（ PCRF, Policy and Charging Rules Function)、 位置服务器（Location Server ), 呈现服务器（Presence Server ), AAA服务器 等， 以及位于应用层的应用服务器中的存储（如视频源、 Web应用数据等）与 计算功能（如视频编码、 动态网页生成、 各种应用信息组织 /管理与处理等）， 都通过云计算的方式提供。
TACTP 专门针对某些在用户设备上的云计算应用。 在这类应用中， UE 本地的存储服务和计算服务， 如用户私人数据， 包括图片、 视频、 数据文件、 电子邮件等格式化数据的存储， 以及本地大型应用软件， 如办公类软件、 CAD/CAM/CAE等软件、 网络游戏等， 可能采用云计算方式来提供， 典型地 可以采用 SaaS ( Software as a Server,软件即服务）、 PaaS ( Platform as a Server, 平台即服务）等形式。这时，集成在基站 40的 TACTP起到代理服务器的功能， 包括终结 UE侧云租户端的传输层协议（TCP/UDP )、 压缩和緩存 UE侧云租 户端与云服务器端（例如， 云服务器端中的对应云服务实体）之间的数据。 具 体地， TACTP可汇聚、 压缩或緩存 UE与对应云服务实体之间的数据； 在接 收到 UE向该云服务实体发送的针对该数据的请求时， 向 UE发送该数据， 并 终止向该云良务实体转发该请求。
TACTP终结 UE侧云端的传输层协议（ TCP/UDP )使得基站 40可以实施 传输控制协议层与无线接入层的跨层联合优化， 充分利用无线资源， 最大化系 统吞吐量。 TACTP汇^ /压缩 /緩存 UE侧云租户端与对应云服务实体之间的数 加快系统对 UE侧云租户端的响应速度，从而改善用户获得 SaaS或 PaaS等服 务的体验。 例如， 终端用户使用云存储方式保存他的图片和视频数据， 对于一 些经常使用的图片和视频片段， TACTP可以进行緩存， 从而加快用户获取这 些数据的速度， 提升用户体验。
图 5是本发明一个实施例的云计算架构的示意结构图。 图 5的架构中， 中心云采用平台云 （ Platform Cloud, 即 PaaS ) 方式。
如图 5所示， 平台云 50上有 3类应用， 即无线网络功能应用 51、 第三方 应用 52和终端云应用 53, 分别与 eNB+中的 WNFCT、 ASCT和 TACTP云端 功能对应， 提供服务器端的功能。 无线网络功能应用 51和第三方应用 52支持多租户 （Multi-tenant ), 即一 个虚拟服务器可以同时支持多个 UE。典型地，无线网络功能应用 51典型地由 移动网络设备商提供， 而后两类应用 52和 53则由移动宽带内容提供商提供。
平台云 50 为应用的开发和运行提供了丰富的软件开发工具包（SDK, Software Development Kit ) 54, 典型地包括编程语言、 软件框架、 数据存储模 型、 函数库、 应用开发与调试工具等等。 在 SDK之下是平台层 55, 负责为应 用提供基于虚拟服务器的运行环境（Runtime Environment ), 网络应用开发框 架、 Web2.0 应用接口等。 平台层 55 之下为无线网络 API ( Application Programming Interface, 应用编程接口） 56和云计算基础设施 API 57, 分别为 平台层 55及上层提供与无线网络相关的应用编程接口， 以及与数据中心等云 计算基础设施相关的应用编程接口。
无线网络 API 56的一个作用是为无线网络功能应用 51提供 API,从而使 得中心云可以完成无线网络相关的数据存储（如签约用户业务订购信息、用户 帐号信息、用户位置信息等）和计算功能（如数据库搜索和查询、数据加密等） 功能， 即 HLR/HSS、 PCRF、 Location Server, Presence Server, AAA Server等 网元的功能。 无线网络 API 56的另外一个作用是， 向第三方应用 52提供从 eNB+获得的无线网络相关的信息， 如无线链路瞬时 SINR、 编码调制方式、 无 线信道条件（平均路损、 平均 SINR等）、 空口负载状态等信息， 从而便于第 三方应用 52利用这个底层信息进行跨层优化， 如进行信道信源联合编码等。 同时， 第三方应用 52也可以将应用相关的信息， 如业务类型、 QoS等信息， 传递给无线网络 API 56, 这样 eNB+也可以通过 Z2接口获得这些应用相关的 信息， 从而优化无线传输通道， 为应用提供有效的 QoS保证。
如前所述， 由于 ASCT和 TACTP集成在 eNB+中， 因此， 它们直接终结 和 UE侧的传输层协议（ TCP/UDP ), 因此可以直接完成传输控制协议层与无 线接入层的跨层联合优化， 而不需要中心云参与。 另外， TACTP所具有的压 与， 而由 TACTP自主完成。 而实施有效的 QoS保证、 信道信源联合编码等， 则通过上述无线网络相关的应用编程接口， 由中心云和 eNB+共同完成。
下面进一步说明 UE在本发明提出的网络架构中如何接入无线通信网络 并使用 MBB ( Mobile Broadband, 移动宽带）业务和终端云业务。 当 UE处于 eNB+的覆盖区时， 通过现有的无线空口接入过程， UE和 eNB+的无线网络功 能实体（包括接入层和非接入层功能 )之间建立起一个或多个无线网络承载通 道， 从而在 UE的应用层和 eNB+的上层功能实体（应用服务器云租户 ASCT 和终端应用云租户代理 TACTP )之间建立起 IP传输通道。其中，在 UE和 eNB+ 的无线网络功能实体之间建立无线网络承载通道的过程中， eNB+的无线网络 功能云租户 WNFCT功能实体通过云计算方式，从中心云获得无线网络功能相 关的控制服务， 如用户签约数据的查询、 用户鉴权、 对无线网络承载通道的策 略控制、 计费等。
当 UE的应用层运行通常的 MBB业务时， UE侧的移动宽带应用的 Client 端的传输层 ( TCP/UDP ), 终结在 eNB+中的 ASCT功能实体， ASCT则采用 云计算的方式， 通过集成在 eNB+中的应用服务器的云端， 由数据中心通过虚 拟服务器等形式提供现有技术中的应用服务器功能。 这样， 从 UE看来， 现有 技术中的应用服务器就处于 eNB+中。 如前所述， 位于数据中心的第三方应用 负责将业务类型、 QoS等信息传递给无线网络相关的应用编程接口， eNB+中 的 ASCT功能实体则通过 Z2接口获得这些应用相关的信息， eNB+中的无线网 络功能实体则通过与 ASCT的内部接口，获取所述应用相关的信息，从而对业 务提供有效的 QoS保证。 同时， 由于 ASCT终结了 UE侧移动宽带应用 Client 端的传输层协议， 并且可以从 eNB+中的无线网络功能实体获得实时的无线链 路和无线资源的状态信息（如无线链路的编码调制信息、 无线信道条件、 空口 负载状态等）。 因此， eNB+可以实施传输控制协议层与无线接入层的跨层联合 优化， 充分利用无线资源， 最大化系统吞吐量。 另夕卜， ASCT还能利用从 eNB+ 中的无线网络功能实体获得实时的无线链路和无线资源的状态信息， 并通过 Z2接口传递到数据中心的无线网络相关的应用编程接口， 从而向第三方应用 APP提供从 eNB+获得的无线网络相关的信息， 如无线链路瞬时 SINR、 编码 调制方式、 无线信道条件（平均路损、 平均 SINR等）、 空口负载状态等信息， 从而便于第三方应用 APP利用这个底层信息进行跨层优化， 如进行信道信源 联合编码， 即对包含视频、 图像等媒体的业务， 实施信道信源的联合编码， 即 根据实时的无线链路状态信息 （如信号与干扰 /噪声功率比 SINR ), 基于系统 吞吐量最大和保证用户体验不变的原则，联合选择最优的视频、 图像等媒体的 编码方式和编码速率、 无线链路的信道编码方式和调制方式等。 当 UE直接通过 SaaS、 PaaS等形式获得云服务时，集成在 eNB+的 TACTP 起到代理服务器的功能， 包括终结 UE侧云端的传输层协议（TCP/UDP 压 缩和緩存 UE侧云端与对应云服务实体之间的数据。 其中， 终结 UE侧云端的 传输层协议（TCP/UDP )使得 eNB+可以实施传输层 ( TCP/UDP )与无线接入 层的跨层联合优化， 充分利用无线资源， 最大化系统吞吐量。 汇聚 /压缩 /緩存 UE侧云端与对应云服务实体之间的数据可以降低 UE侧云端与对应云服务实 体之间的数据传输延迟和数据率， 加快系统对 UE侧云端的响应速度， 从而改 善用户获得 SaaS或 PaaS等服务的体验。
第三方应用 52和终端云应用 53 可以是运行在运营商提供的数据中心及 相应的软件平台 （例如， 图 5所示的平台云）上的应用， 也可以是来自其它运 营商的数据中心及相应的软件平台上的应用， 或者是一些大型 IT公司的数据 中心及相应的软件平台上的应用， 为此， 可以通过图 5所示的 Y1接口实现不 同类型云之间的互联。
一种较筒单的云间互联的方式是使用代理服务器机制。 图 6是本发明一 个实施例的云计算系统的示意结构图。 图 6的云计算系统 60包括多个云服务 器端 61a、 61b和 61c, 每个云服务器端 61a、 61b和 61c和各自的增强型基站 eNB+连接。 应注意， 图 6中各个网元的数目只是示意性的， 不对本发明实施 例的范围构成限制。
连接到云服务器端 61a的 eNB+中激活了一个应用服务器云租户（ ASCT ), 它对应的虚拟服务器在云服务器端 61a中， 即图 6中所示的 VM1。 VM1并不 直接提供应用， 因为这个应用并不是由云服务器端 61a直接提供的， 而是由云 服务器端 61c提供的。 因此， VM1相当于一个背靠背 （Back-to-Back )代理， 即对连接到云服务器端 61a的 eNB+是运行相应应用的虚拟服务器， 但对实际 运行应用的云服务器端 61c中的虚拟服务器 VM2而言， 相当于一个云租户。 这样 VM1 可以从 VM2获得相应的云服务， 并将相应的服务传递到云服务器 端 61a中的 eNB+的相应 ASCT功能。
图 7是本发明一个实施例的云计算系统中移动性管理的示意图。 图 7中， 与图 1相同或相似的部分使用相同的附图标记。
下面结合图 1描述移动性管理的详细过程。 当 UE从一个 eNB+ 12a的覆 盖范围移动到另外一个 eNB+ 12b的覆盖范围时， 将发生两个层次的切换， 即 无线空口切换和云租户端的切换。由于 eNB+ 12a和 12b之间直接有 X2+接口， 因此， 可以利用该 X2+接口完成跨 eNB+ ( Inter-eNB+ ) 的无线接入层的切换 ( Handover )和无线非接入层的迁移（Relocation ), 具体的切换过程， 与现有 LTE技术中基于 X2接口的跨 eNB的无线接入层切换类似， 区别之处在于，在 现有 LTE技术中无线非接入层功能实体位于核心网， 因此跨 eNB的无线接入 层切换并不直接导致无线非接入层的迁移，但在本发明实施例中， 由于无线接 入层和非接入层同时集成在 eNB+中，因此，无线非接入层的迁移是和跨 eNB+ 的无线接入层切换同时进行的。 这时， UE的 IP地址也将随跨 eNB+的无线非 接入层的迁移重新配置。
WNFCT、 ASCT和 TACTP云租户端的切换也和跨 eNB+的无线接入层切 换同时进行。 由于采用云计算， 实际运行应用的实体本身是位于数据中心的虚 拟服务器， 因此一个 UE对应的云租户端的切换， 不影响对应的无线网络功能 应用、 第三方应用和终端云应用的运行状态。 这样， 对应用而言， 当 UE发生 跨 eNB+的移动时， 仅仅是 UE对应的云租户端发生切换， 而运行于中心云虚 拟服务器上的应用并不受影响。 因此， 可以以采用类似"软切换 "方式进行 WNFCT、 ASCT和 TACTP云租户端的切换。
具体来说， UE发生跨 eNB+的无线接入层切换和 /或无线非接入层迁移时， 在源 eNB+ 12a运行该 UE的云租户端的同时， 在目标 eNB+ 12b中启动该 UE 的云租户端的拷贝，这两个云租户端完全同步到中心云中的相应的应用。这样， 就能保证该 UE的应用层无缝的移动性， 当整个跨 eNB+的移动过程完成后， 再停止源 eNB+ 12a中的该 UE的云租户端。
图 8是本发明另一实施例的云计算系统的示意结构图。 图 8的云计算系 统 80是无线云 （Wireless Cloud ) 与应用云集成的网络架构。 无线云又称为 C-RAN ( Cloud RAN, 云接入网）， 是最近关注较多的一个无线接入网架构。 该架构的主要特征是将传统基站的基带处理单元（BBU, Base Band Unit )和 射频单元分离。 例如， 多个基站的 BBU集中在一起， 组成一个或多个无线云 81a、 81b, 并通过光纤等宽带传输线路与远程射频单元（RRU, Radio Remote Unit )相连。
无线云 81a、 81b 完成无线蜂窝系统的所有功能 （无线接入层功能如 PHY/M AC/RLC/PDCP , 以及非接入层功能如 L3协议、 PDN网关等）。 另夕卜， 无线云 81a、 81b还可以包括图 4所示无线非接入层之上的三个功能实体， 即 WNFCT、 ASCT和 TACTP, 并分别通过 Zl、 Z2和 Z3接口与云服务器端（或 者称为中心云） 82相连。 无线云 81a、 81b之间采用 X3接口互联， 该接口类 似图 4中的 X2+接口， 用于支持无线云间的移动性。
对应到图 2的基站， 在图 8的实施例中， 接收模块 21位于 RRU中， 第 一处理模块 22位于 BBU (即位于 BBU组成的无线云 81a或 81b ) 中。 BBU 集中有利于利用云计算技术实现基带处理资源的虚拟化，从而实现灵活的基带 处理资源共享，解决业务量分布的潮汐效应， 并可实现多小区之间的联合信号 处理， 消除小区间的干扰， 提高系统容量。
本发明实施例使移动运营商能够提供管道和云的统一业务平台， 从而拓 展移动运营商的业务范围，使移动运营商不但能提供管道服务，还可以提供存 储、 计算等信息服务。 另外， 本发明实施例便于实施应用层 /传输层与无线承 载底层的跨层优化， 从而提升系统性能， 并且便于获知应用的 QoS信息， 使 系统能够为各类应用提供端到端的 QoS保证。
图 9是本发明一个实施例的服务处理方法的流程图。 图 9的方法由基站 执行， 例如图 1中的 eNB+或上述基站 20-40等。
91 , 与 UE之间建立无线网络承载通道。 例如， 可通过实现现有的无线网 络的接入层协议和非接入层协议， 建立上述无线网络承载通道。
92, 通过无线网络承载通道接收 UE的服务请求。
93, 解析 UE的服务请求中的请求内容，根据请求内容中需要由云服务器 端处理的内容生成云服务访问请求。
在解析得到请求内容之后， 基站自主决定如何进行处理。 例如， 对于基 站自己能够处理的内容， 如跨层优化、联合编码处理、数据压缩 /汇¾ /緩存等， 则可以由基站执行这些处理。 对于需要云服务器处理的内容， 如数据存储 /计 算等， 则基站可向相应的云服务器端发送云服务访问请求， 以请求云服务器端 进行相应的处理。
94, 发送云服务访问请求到云服务器端， 并将云服务器端的相应处理结 果通过无线网络承载通道返回给 UE。
这样， 从用户设备的角度来看， 犹如应用服务器就处于基站中。 用户设 备直接向基站进行服务请求（而非现有技术中那样， 用户设备向应用服务器进 行服务请求， 基站只是筒单地在接入层转发该服务请求）， 即由基站终结了该 用户设备的传输层协议。而现有技术中，用户设备向应用服务器进行服务请求， 基站不会解析服务请求中的请求内容， 只是根据服务请求的目的地址等信息 (这些信息一般在服务请求包的包头中），筒单地查找路由并转发该服务请求。
本发明实施例的基站与用户设备之间建立无线网络承载通道， 从而终结 了用户设备的接入层协议。 另外， 从传输层协议的层面来看， 本发明实施例的 基站不是筒单地转发用户设备的服务请求， 而是解析服务请求中的请求内容， 并根据请求内容自己进行处理或请求云服务器端协助进行处理，使得用户设备 侧的传输层协议和接入层协议均终结于基站，因此本发明实施例能够实现传输 层和接入层的跨层优化。 行的其他过程。 下面结合图 3的基站 30举例说明。 例如， 无线网络功能模块 可实现无线网络的接入层协议和非接入层协议，与 UE之间建立一个或多个网 络 7|载通道。
可选地， 作为另一实施例， 第一处理模块 22可以获取服务请求所针对的 业务的应用属性信息和 /或信源编码信息等应用相关的信息。 例如， 第一处理 模块 22可以在解析 UE的服务请求中的请求内容时， 获取这些应用相关的信 息； 或者， 第一处理模块 22也可以从其他源 （例如， 与应用相应的云服务器 端或云服务实体）获取应用相关的信息。 无线网络功能模块 24还可以从第一 处理模块 22获取应用属性信息和 /或信源编码信息， 并利用应用属性信息和 / 或信源编码信息实现业务质量保证。
可选地， 作为另一实施例， 无线网络功能模块 24可以获得无线网络承载 通道上的无线链路和 /或无线资源的实时状态信息等应用相关的信息。 无线网 信息， 本发明对此不作限制。 第一处理模块 22还可以从无线网络功能模块 24 获无线链路和 /或无线资源的实时状态信息， 并根据无线链路和 /或无线资源的 实时状态信息， 完成传输控制协议层与无线接入层的跨层联合优化。 另外， 第 一处理模块 22还可以将无线链路和 /或无线资源的实时状态信息提供给第三方 应用， 以便第三方应用利用无线链路和 /或无线资源的实时状态信息进行跨层 优化。 此外， 无线网络功能模块 24在与 UE之间建立无线网络承载通道时， 也 可以参考上述应用相关的信息。
可选地， 作为另一实施例， 第三处理模块 25可以汇聚、 压缩或緩存 UE 与对应云服务实体之间的数据； 在接收到该 UE向该云服务实体发送的针对上 述数据的请求时， 向该 UE发送上述数据， 并终止向该云服务实体转发上述请 求。
可选地， 作为另一实施例， 移动性管理模块 26可以当 UE发生跨所述基 站的无线接入层切换和 /或无线非接入层迁移时， 在当前基站的第一处理模块 为 UE服务的同时，在目标基站的第一处理模块中启动上述当前基站的第一处 理模块的拷贝，将上述当前基站的第一处理模块和上述目标基站的第一处理模 块同步到云服务器端中的相应的应用。
根据本发明实施例的云计算系统可包括多个云服务器端（例如图 6的 61a、 61b和 61c ), 多个云服务器端之间相互连接。每个云服务器端与一个或多个上 述基站 20-40连接。
