本申请实施例涉及云技术(Cloud technology)，云技术是指在广域网或局域网内将硬件、软件、网络等系列资源统一起来，实现数据的计算、储存、处理和共享的一种托管技术。
云技术基于云计算商业模式应用的网络技术、信息技术、整合技术、管理平台技术、应用技术等的总称，可以组成资源池，按需所用，灵活便利。云计算技术将变成重要支撑。技术网络系统的后台服务需要大量的计算、存储资源，如视频网站、图片类网站和更多的门户网站。伴随着互联网行业的高度发展和应用，将来每个物品都有可能存在自己的识别标志，都需要传输到后台系统进行逻辑处理，不同程度级别的数据将会分开处理，各类行业数据皆需要强大的系统后盾支撑，只能通过云计算来实现。
参见图2，图2是本申请实施例提供的ETSI MEC架构示意图，ETSI MEC工作组定义了用于移动网络的边缘计算平台架构。其中，移动边缘应用(Mobile Edge Applications)以实例化的形式部署在移动边缘主机(Mobile Edge Host)上，具备提供或使用移动边缘服务(Mobile Edge Service)的能力。移动边缘主机为包含移动边缘平 台及虚拟化基础设施的实体，为各类移动边缘应用提供计算、存储及网络资源。其底层的虚拟基础设施(Virtualization Infrastructure)为各个上层移动边缘应用提供计算、存储及网络资源。移动边缘平台(Mobile Edge Platform)在移动边缘主机上运行各类移动边缘应用所需的功能集，可提供并使用各种移动边缘服务。移动边缘应用可通过订阅调用移动边缘服务获取底层网络所开放的能力，例如无线网络信息、用户位置信息及网络带宽管理等功能。移动边缘主机水平(Mobile Edge Host Level)是管理组件，用于执行对特定移动边缘平台、移动边缘主机及其运行的移动边缘应用的特定功能管理。移动边缘系统水平(Mobile Edge System Level)通过维护对整个移动边缘系统的全局视图进行系统管理。在移动边缘系统水平方面，ETSI引入了移动边缘编排器作为核心组件对整个系统进行全局化管理。在移动边缘主机水平方面，ETSI定义了应用规则及需求(Application Rules and Requirements)，针对各类移动边缘应用设置相关的规则与需求，主要包括：所需资源、最大延迟/时延、所需或有用的服务、流量规则、域名系统(Domain Name System，DNS)规则及移动性支持等。
ETSI MEC架构主要用于本地私有网络内运行的业务(例如，企业内部应用)，它不具备实现中心云与边缘数据中心协同的能力。互联网业务的处理逻辑则较为复杂。通常需要在位于网络中心位置的数据中心内引入接入层，对处理具体业务请求的服务器进行调度。基于ETSI MEC架构部署的互联网业务，无法与外部数据中心内的接入层功能进行交互，导致整体业务逻辑被破坏，且需要对业务前端，即应用(Application，APP)，进行重构。此外，由于ETSI MEC架构建立了私有封闭的业务管理体系，互联网业务后台系统也无法对部署在ETSI MEC架构上的业务服务器进行有效管控。
当ETSI MEC架构用于支持应用小程序访问本地业务服务器时，业务开发者必须要求每个边缘数据中心根据指定的业务域名为本地业务服务器分配应用小程序许可网段内的互联网协议(Internet Protocol，IP)地址。如果业务域名解析由中心云内的DNS服务器解析，则位于不同边缘数据中心内的本地业务服务器必须分配统一的IP地址。如果业务域名解析由边缘云内的DNS服务器解析，则业务开发者必须在每个边缘数据中心内创建相应的DNS记录，操作十分繁杂。如果业务开发者直接使用ETSI MEC架构为本地业务服务器分配的IP地址，则可能因为该地址不在应用小程序许可的网段，而无法实现业务访问。
基于上述技术问题，本申请实施例提供一种无线通信方法，可以将业务的接入层功能及业务处理服务器部署在边缘数据中心，利用边缘数据中心的低时延特性，提升业务访问能力，并且能够利用中心云内的业务调度器对边缘业务进行有效合理的管控。
下面对本申请实施例提供的无线通信方法的具体实施过程进行详细的描述。
图3是本申请实施例提供的无线通信方法200的流程示意图，无线通信方法200可以由图1所示的边缘路由交换机151执行。如图3所示，无线通信方法200至少包括S210至S220，详细介绍如下：
在S210中，边缘路由交换机将终端设备发往边缘数据中心内的业务服务器的业务请求的目标地址，从第一IP地址替换为第二IP地址，其中，第一IP地址为业务服务器的虚拟地址，第二IP地址为业务服务器在边缘数据中心的真实地址。
在S220中，将业务服务器发往终端设备的针对业务请求的业务响应的源地址，从第二IP地址替换为第一IP地址，以使终端设备与业务服务器进行通信。
在一些实施例中，终端设备在访问边缘数据中心内的业务服务器时，使用第一IP地址(即业务服务器的虚拟地址)，且在边缘数据中心内，第一IP地址会替换为第二IP地址(即业务服务器在边缘数据中心的真实地址)。边缘数据中心内的业务服务器在向终端设备反馈时，使用第二IP地址(即业务服务器在边缘数据中心的真实地址)，且在 边缘数据中心内，第二IP地址会替换为第一IP地址(即业务服务器的虚拟地址)。
也就是说，在实际实施时，通过第一IP地址与第二IP地址之间的相互转换，实现终端设备与业务服务器之间的通信，从而，部署在边缘数据中心内的业务服务器可以处理终端设备的业务请求，实现基于移动边缘计算的互联网业务交付，可以缩短业务时延，提升用户体验。此外，本申请实施例提供的无线通信方法不会影响互联网现有的业务逻辑，也不用修改互联网业务前端，业务小程序开发者可利用中心云内的业务调度器(即中心云内的业务后台系统)对边缘业务进行管控，具有较强的适用性。
在一些实施例中，终端设备发往业务服务器的业务请求可以称之为IP数据包，同理，业务服务器发往终端设备的业务响应也可以称之为IP数据包。
在一些实施例中，第一IP地址可以为根据业务许可的IP地址网段分配的。或者，第一IP地址也可以为根据终端设备的业务小程序许可的IP地址网段分配的。也就是说，第一IP地址为业务许可的IP地址，或者，第一IP地址为终端设备的业务小程序许可的IP地址。
在一些实施例中，第二IP地址可以为根据运营商许可的IP地址网段分配的。也就是说，第二IP地址为运营商许可的IP地址。
在一些实施例中，第一IP地址和第二IP地址为边缘业务管理器为边缘数据中心内的业务服务器分配的。
例如，本地的业务服务器在边缘数据中心进行部署时，边缘业务管理器为其分配两个IP地址，一个是业务服务器在边缘数据中心内的真实地址(第二IP地址)，一个是根据业务小程序许可的IP地址网段分配的虚拟地址(第一IP地址)。
在一些实施例中，第一IP地址与第二IP地址之间的相互转换通过边缘业务管理器创建的第一对应关系实现，其中，第一对应关系包括第一IP地址与第二IP地址之间的对应关系。
在实际实施时，边缘业务管理器可以在边缘路由交换机中创建第一对应关系，从而，边缘路由交换机可以基于第一对应关系实现第一IP地址与第二IP地址之间的相互转换。
需要说明的是，在一些实施例中，第一对应关系还可以适用于边缘数据中心内的其他业务服务器，即第一对应关系还可以包括其他业务服务器的虚拟地址与真实地址之间的对应关系。
此外，第一对应关系也可以称之为第一映射关系、第一映射表格等等，本申请实施例对此并不限定。
本申请实施例提供的无线通信可用于云游戏、视频及车联网等互联网业务。
在一些实施例中，终端设备与业务服务器之间通过用户面功能实体实现数据转发。
在一些实施例中，S210可通过如下方式实现：接收用户面功能实体转发的终端设备发往业务服务器的业务请求；将业务请求的目标地址从第一IP地址替换为第二IP地址；在业务请求的目标地址从第一IP地址替换为第二IP地址之后，将业务请求发送至业务服务器。
在一些实施例中，S220可通过如下方式实现：接收业务服务器发往终端设备的针对业务请求的业务响应；将业务响应的源地址从第二IP地址替换为第一IP地址；在业务响应的源地址从第二IP地址替换为第一IP地址之后，通过用户面功能实体将业务响应发送至终端设备。
图4是本申请实施例提供的无线通信方法300的流程示意图，无线通信方法300可以由图1所示的用户面功能实体120执行。如图4所示，无线通信方法300至少包括S310至S340，详细介绍如下：
在S310中，将中心云内的业务调度器返回的针对终端设备发送的业务调度请求的 业务调度响应发送至终端设备，业务调度响应携带第一IP地址，第一IP地址为边缘数据中心内的业务服务器的虚拟地址。
在一些实施例中，首先，将终端设备发送的业务调度请求转发至中心云内的业务调度器；然后，接收中心云内的业务调度器返回的针对终端设备发送的业务调度请求的业务调度响应；最后，将业务调度响应发送至终端设备。
在一些实施例中，本地的业务服务器在边缘数据中心进行部署时，边缘业务管理器为其分配两个IP地址，一个是业务服务器在边缘数据中心内的真实地址(第二IP地址)，一个是根据业务小程序许可的IP地址网段分配的虚拟地址(第一IP地址)。此外，边缘业务管理器将第一IP地址告知中心云内的业务调度器。
在一些实施例中，在中心云内的业务调度器确定边缘数据中心内的业务服务器能够处理业务调度请求的情况下，接收业务调度器返回的针对终端设备发送的业务调度请求的业务调度响应(携带第一IP地址)。
也就是说，中心云内的业务调度器在接收到终端设备发送的业务调度请求之后，对业务调度请求是否可以被边缘数据中心内的业务服务器处理进行判断，当确定业务调度请求可以被边缘数据中心内的业务服务器处理时，向终端设备返回第一IP地址。
在S320中，接收终端设备发送的业务请求，业务请求的目的地址为第一IP地址。
在一些实施例中，终端设备在接收到中心云内的业务调度器返回的第一IP地址之后，以第一IP地址为目的地址，向边缘数据中心内的业务服务器发出业务访问请求。此种情况下，用户面功能实体接收终端设备发送的业务请求。
在S330中，根据第一IP地址将业务请求发送至边缘数据中心内的边缘路由交换机，以使边缘路由交换机在将业务请求的目的地址从第一IP地址替换为第二IP地址之后，将业务请求发送至业务服务器，其中第二IP地址为业务服务器在边缘数据中心的真实地址。
在一些实施例中，边缘业务管理器可以在用户面功能实体中创建IP地址列表，在第一IP地址属于边缘业务管理器创建的IP地址列表的情况下，将业务请求发送至边缘数据中心内的边缘路由交换机。
也就是说，用户面功能实体接收到终端设备发送的业务请求之后，通过检测业务请求的目标地址，当发现其符合向边缘数据中心内的边缘路由交换机转发的条件时，即可将业务请求发送至边缘数据中心内的边缘路由交换机。
终端设备在访问边缘数据中心内的业务服务器(如下载文件，下载视频)时，使用第一IP地址(即业务服务器的虚拟地址)，且在边缘数据中心内，边缘路由交换机将第一IP地址替换为第二IP地址(即业务服务器在边缘数据中心的真实地址)，即可访问业务服务器。
在S340中，在边缘路由交换机将业务服务器返回的针对业务请求的业务响应的源地址，从第二IP地址替换为第一IP地址之后，将业务服务器返回的业务响应发送至终端设备。
边缘数据中心内的业务服务器在向终端设备反馈时，使用第二IP地址(即业务服务器在边缘数据中心的真实地址)，且在边缘数据中心内，边缘路由交换机将第二IP地址替换为第一IP地址(即业务服务器的虚拟地址)，即可通过用户面功能实体反馈给终端设备。
在一些实施例中，终端设备在访问边缘数据中心内的业务服务器时，使用第一IP地址(即业务服务器的虚拟地址)，且在边缘数据中心内，第一IP地址会替换为第二IP地址(即业务服务器在边缘数据中心的真实地址)。边缘数据中心内的业务服务器在向终端设备反馈时，使用第二IP地址(即业务服务器在边缘数据中心的真实地址)，且在 边缘数据中心内，第二IP地址会替换为第一IP地址(即业务服务器的虚拟地址)。
也就是说，在实际实施时，通过第一IP地址与第二IP地址之间的相互转换，实现终端设备与业务服务器之间的通信，从而，部署在边缘数据中心内的业务服务器可以处理终端设备的业务请求，实现基于移动边缘计算的互联网业务交付，可以缩短业务时延，提升用户体验。此外，本申请实施例提供的无线通信方法不会影响互联网现有的业务逻辑，也不用修改互联网业务前端，业务小程序开发者可利用中心云内的业务调度器(即中心云内的业务后台系统)对边缘业务进行管控，具有较强的适用性。
在一些实施例中，第一IP地址可以为根据业务许可的IP地址网段分配的。或者，第一IP地址也可以为根据终端设备的业务小程序许可的IP地址网段分配的。也就是说，第一IP地址为业务许可的IP地址，或者，第一IP地址为终端设备的业务小程序许可的IP地址。
在一些实施例中，第二IP地址可以为根据运营商许可的IP地址网段分配的。也就是说，第二IP地址为运营商可的IP地址。
在一些实施例中，第一IP地址和第二IP地址为边缘业务管理器为边缘数据中心内的业务服务器分配的。
例如，本地的业务服务器在边缘数据中心进行部署时，边缘业务管理器为其分配两个IP地址，一个是业务服务器在边缘数据中心内的真实地址(第二IP地址)，一个是根据业务小程序许可的IP地址网段分配的虚拟地址(第一IP地址)。
在一些实施例中，第一IP地址与第二IP地址之间的相互转换通过边缘业务管理器创建的第一对应关系实现，其中，第一对应关系包括第一IP地址与第二IP地址之间的对应关系。
边缘业务管理器可以在边缘路由交换机中创建第一对应关系，从而，边缘路由交换机可以基于第一对应关系实现第一IP地址与第二IP地址之间的相互转换。
需要说明的是，在一些实施例中，第一对应关系还可以适用于边缘数据中心内的其他业务服务器，即第一对应关系还可以包括其他业务服务器的虚拟地址与真实地址之间的对应关系。
此外，第一对应关系也可以称之为第一映射关系、第一映射表格等等，本申请实施例对此并不限定。
