具体实施方式
以下结合附图及实施例，对本公开进行进行说明。此处所描述的实施例仅仅用以解释本公开，并不用于限定本公开。
相关技术中，国际标准组织宽带论坛(Broadband Forum，BBF)和第三代合作项目(the 3rd Generation Partnership Project，3GPP)，在固移融合(Fixed Mobile Convergence，FMC)领域进行了标准化合作工作，标准化合作工作正在开展过程中，其中，固定通信网络相关的功能在BBF展开，移动通信网络的需求功能则在3GPP展开，此标准化合作工作的目的是实现固定通信网络和移动通信网络在网络结构及业务层面的深度融合，融合的宗旨是将不同类型的接入网统一接入到同一张5G核心网。BBF标准组织对固移融合的标准规范，给出了三条演进路线：
1.整合模型(Integration model)，接入网通过引入有线5G接入网(Wireline-5G Access Network，W-5GAN)设备，实现与5G核心网(5G Core，5GC)的融合演进，此为融合演进的终极目标。
2.互通模型(Inter-working model)，通过在固定通信网络继续沿用宽带网络网关(Broadband Network Gateway，BNG)设备，加入互通设备5G固定移动互通功能(5G Fixed Mobile Inter-working Function，5G-FMIF)设备，来实现与5GC的融合演进。此为融合演进的过渡阶段。
3.共存模型(Co-existence model)。共存模型的融合特点是：固定通信网络和移动通信网络走统一的传输城域网，但对于接入和核心还沿用原网络部署，以此减少对城域网的部署和维护。此为融合演进的前期部署推荐。
整合模型和互通模型的网络融合部署，对固定通信网络和5G核心网络的互通设备作了较大改动；整合模型采用互通设备5G接入网关功能(5G Access Gateway Function，5G-AGF)接入到5G核心网，互通模型采用互通设备5G-FMIF接入到到5G核心网，实现用户的注册、认证等。互通设备在通信控制面支持3GPP定义的N1、N2、N3等接口技术。对于共存模型，由于接入网和核心网还是沿用相关技术中的设备，只是传输承载网的融合，对现网设备改动较小，因此，可作为到5G移动通信网络融合演进的早期方案。BBF对共存场景应用模型 进行了说明(参见BBF FMC-407文件)，也给出了共存模型的参考架构，图1为本公开实施例中共存模型的参考架构的示意图。图1中，AN表示接入网络(Access Network，AN)，5G-RG表示5G住宅网关(5G Residential gateway，5G-RG)，FMIF表示固定移动互通功能(Fixed Mobile Inter-working Function，FMIF)，FN-RG表示固网家庭网关(Fixed Network Residential Gateway，FN-RG)，ARCF表示接入网络资源控制功能(Access network Resource Control Function，ARCF)，U表示用户侧参考节点(U reference point，U)表示，V表示网络侧参考节点(V reference point，V)。
基于上述记载的内容，提出以下多个实施例。
实施例一
本公开实施例提出了一种移固共存融合系统，可以实现固移融合。

本公开实施例中，由于固定通信网络承载层级一般为3级，因而，将移动通信核心网用户面设备下沉至移固承载IP城域网的汇聚层，可以解决移动通信业务承载层级过多，流量绕行及网络延时时间长等问题，一方面可以减少移动通信网络的承载层级，实现承载网络的扁平化，降低网络时延；另一方面移动通信城域网通过与固定通信城域网络融合到同一个城域承载网，降低网络建设成本，提升网络运维效率等。

本公开实施例中，移动通信核心网用户面设备包括PGW和SGW，本公开实施例中，可以将SGW和PGW合并，简称为S/PGW。为解决移动通信LTE网络承载层级多，及业务绕行的问题，通过将移动通信核心网用户面设备(S/PGW User Plane，S/PGW-U)下沉至汇聚层，将承载层级缩减为3级，从而实现移动承载网络的极大扁平化；即，通过网络扁平化改造，降低网络建设成本，降低网络传送时延，及提升网络维护效率等。
可选地，MSG中的固定通信核心网用户面设备(MSG-U)和固定通信核心网控制面设备(MSG-C)设置为采用转控分离架构实现；在一实施例中，所述转控分离架构可以基于软件定义网络(Software Defined Network，SDN)和网络功能虚拟化(Network Function Virtualization，NFV)实现；MSG可以为转控分离体系架构(也称为转控分离架构)，通过构建基于软件虚拟化SDN、NFV技术的MSG设备来实现对固定通信网络和移动通信网络的统一汇聚接入，从而实现固定通信网络和移动通信网络业务的共存融合。

实施例二
在本公开实施例一的基础上，进行举例说明。
根据前述实施例记载的内容，通过图4给出了本公开实施例的移固共存融合系统的网络架构体系示意图，图4中，虚线表示控制报文，实现表示转发报文；MSG-C和S/PGW-C处于控制云，MSG-U处于转发云，当移动通信业务的 用户(如手机用户)发起网络接入请求时，可以基于综合业务光传输网(Universal Transport Network over Fiber，UTN)汇聚、移动网络数据业务(简称为移网数据业务)、UTN接入，实现与S/PGW-U的通信；固定通信业务可以包括宽带业务、IPTV业务、专线业务或VPN业务，可选地，固定通信业务的接入可以通过SW实现；转发云中的MSG-U可以通过核心路由器(Core Router，CR)实现到因特网(Internet)的访问。
对于前述实施例和图4所示的移固共存融合系统，本公开实施例提出了上述移固共存融合系统的网络改造流程。
图5为本公开实施例的移固共存融合系统的网络改造流程的示意图，如图5所示，该流程可以包括：步骤500至步骤507。
步骤500：网络拓扑层次划分。
进行准备工作，对网络整体拓扑进行层次划分，根据转控分离的原则，分为控制面网络和用户面网络，所述控制面网络命名为一级控制数据中心(Data Center，DC)，所述用户面网络命名为二级转发DC，并设置DC间的承载网、IP城域网以及eNB。
步骤501：多级DC网络资源部署。
进行多级DC内部资源部署规划及业务规划，在一实施例中，DC内部资源部署规划及业务规划涉及不同网络拓扑层次的处理。
本公开实施例中，一级控制DC为控制面网络，S/PGW-C设置为实现核心网S1-MME接口业务，MSG-C设置为实现宽带用户接入的协议协商、用户认证、接入控制、用户管理等。二级转发DC为转发面网络，包括S/PGW-U和MSG-U，为打通用户面业务，可通过新加入SW设备来实现两者间通信，在一实施例中，SW设备为可选项。
在一实施例中，一级控制DC和二级转发DC之间，通过承载网、IP城域网等来实现DC间的通信；二级转发DC与互联网之间有CR承载网衔接。
这里的业务部署包括控制面网络和转发面网络分别的业务部署；控制面信令及管理信息的传输，采用VXLAN隧道来承载；在进行数据转发面的传输时，可采用如分段路由(Segment Routing，SR)技术实现对数据业务的封装。
步502：一级控制DC网络搭建。
在一实施例中，进行一级控制DC内部组网搭建，一级控制DC内部网络包括S/PGW-C及MSG-C，MSG-C需侧挂验证、授权和记账(Authentication、Authorization、Accounting，AAA)服务器及动态主机配置协议(Dynamic Host  Configuration Protocol，DHCP)服务器，设置为用户AAA身份认证、身份授权、IP地址获取及计费等功能；一级控制DC与二级转发DC设备的L3逻辑链路打通，可实现信令及管理层面的信息传输。
步骤503：二级转发DC网络搭建。
在一实施例中，进行二级转发DC内部组网搭建，二级转发DC内部网络包括S/PGW-U及MSG-U，分别设置为移动通信网络融合后核心网用户面业务下沉至城域汇聚层的移动业务通信，及固定通信网络业务的转控分离架构的用户面业务转发。
根据S/PGW-U与MSG-U地理位置的不同，考虑增加SW设备来完成S/PGW-U与MSG-U的之间数据交互；S/PGW-U可以不是直接与IP城域网直连，而是通过SW设备转接，因此，在二级转发DC内部网络搭建时，增加至少一个SW设备，与IP城域网汇聚设备、S/PGW-U、MSG-U分别进行连接互通，以实现所述S/PGW-U、SW设备、IP城域网汇聚设备、MSG-U之间的通信。
MSG-U支持NAT功能，并侧挂CDN网络，通过NAT地址转换后用户请求到CDN视频源。
步骤504：跨DC间网络搭建。
在一实施例中，跨DC间网络搭建可以通过以下方式实现：
1)一级控制DC与二级转发DC间的逻辑通道VXLAN隧道的部署；
2)二级转发DC与IP城域网之间传输网的互通，实际应用中，可以通过增加SW设备，实现IP城域网、SW设备、及S/PGW-U之间的S1-U无线接入网络(Radio Access Network，RAN)业务通信，同时，支持对S/PGW-U、SW设备、及MSG-U之间的SGi接口业务通信；在外层隧道部署上，可采用SR技术实现。
3)二级转发DC与承载网的互通，实现到因特网的接入。
步骤505：移动VXLAN隧道部署。
在一实施例中，移动VXLAN隧道部署的含义为移动通信业务VXLAN隧道的打通；通过移动通信业务VXLAN隧道的打通，可以实现S/PGW-C与S/PGW-U之间的逻辑通信，上述逻辑通信建立的前提是网元间有确定的IP路由可达链路；在路由打通后，进行移动通信网络VXLAN隧道的部署。
步骤506：固网VXLAN隧道部署。
在一实施例中，固网VXLAN隧道部署的含义为固定通信业务VXLAN隧道的打通；通过固定通信业务VXLAN隧道的打通，可以实现MSG-C与MSG-U 之间的逻辑通信，上述逻辑通信建立的前提是网元间有确定的IP路由可达链路；在路由打通后，进行固定通信网络VXLAN隧道的部署。
步骤507：典型业务部署及验证，结束流程。
在一实施例中，典型业务可以是网络融合业务；网络融合业务的验证，可以通过一些基本业务的加载，来验证融合后的业务运行情况，进而验证网络融合的可行性；示例性地，可以通过固定通信网络IP连接协议(Internet Protocol over Ethernet，IPoE)、点到点连接协议(Point to Point Protocol over Ethernet，PPPoE)用户认证，验证固定通信网络基本业务运行的可靠性，并通过移动S1-MME信令报文的传输，进行移动网络业务运行的可行性验证。
至此，完成了移固共存融合系统的网络改造，可以实现固移网络共存融合。
