具体实施方式
为使本发明要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
应理解，说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施例有关的特定特征、结构或特性包括在本发明的至少一个实施例中。因此，在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外，这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
在本发明的各种实施例中，应理解，下述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
另外，本文中术语“系统”和“网络”在本文中常可互换使用。
下面首先对本申请实施例提供的方案涉及的内容进行介绍。
一般而言，每个基站都是针对一个运营商的，因此它只能和一个运营商的网关相连。目前建设基站时一般是共站共建，即每个运营商发射各自频率的无线信号，广播各自的PLMN，多个基站共享相同的基站站址和回传网络。公共陆地移动网PLMN是由特定的网络运营商控制的移动电话网络。可以通过移动国家码和分配给网络运营商的移动网络码的唯一组合来定义PLMN。移动通信设备上的每个SIM可以支持订制，该订制用于使用相应的无线接入技术(Radio Access Technology，RAT)向PLMN进行注册并且自建设基站导致的基站建设成本高以及各基站间干扰大的在PLMN上进行通信。由于建设多套基站成本高且各占之间干扰也大。
多运营商网络(Multi-operator core network，MOCN)主要背景是当前小型运营商的崛起，同时站址、频谱等资源限制，运营商建网难度不断增大，客户平均每月收益(Average Revenue Per User，ARPU)值的不断下降，对于网络共享的呼声越来越强烈，网络共享是指实现无线网络在不同运营商之间的共享。目前网络资源共建共享已成为了解决网络资源紧张问题的重要途径。
网络共享主要分为这几类：
一、无线接入网络(Radio Access Network，RAN)共享：只共享无线接入 网(MME不共享)，指一个RAN(无线网络)可以连接到多个运营商核心网节点。其中又根据频率是否共享分为：
A：共享频谱(MOCN)
无线设备只发射一个载波，所有运营商公用这个载波，共享硬件资源的同时共享频谱资源。
B：不共享频谱(多运营商RAN(Multi-operator RAN，MORAN))
无线设备同时发射多个载频，承载不同运营商业务。
二、网关核心网络(Gateway Core Network，GWCN)网关共享核心网和无线接入网(MME共享)，是指在共享RAN的基础上，再将核心网部分功能下沉到网关，实现部分核心网共享。
MOCN在实现频谱共享之后，需要重点解决具体的无线资源分配问题，如用户设备(User Equipment，UE)接入个数、无线承载数等在各个运营商之间如何分配。通常做法主要是通过支持每个PLMN的专用用户数和无线承载数的独立配置来实现：
固定分配：运营商A、B固定分配所有资源
半静态分配：运营商A、B各固定分配部分无线资源，剩余部分作为共享资源
资源池：运营商A、B无固定资源分配，两个运营商公用所有的无线资源
过盈分配:运营商A、B固定分配，在特定的条件下，B可占用A的部分资源，但在A需要占用的时候又可将资源抢占回来。
下面结合附图1至7对本申请的方案进行介绍。
如图1所示，本发明实施例的一种多PLMN的数据传输方法，应用于基站，包括以下步骤：
步骤101，在所述基站的P个广域网(Wide Area Network，WAN)口与P个移动管理实体MME之间创建P条逻辑链路；其中，P为公共陆地移动网PLMN的数量，且所述逻辑链路与所述PLMN为一一对应关系。
需要指出的是，本申请中的基站(eNB)是具MOCN功能的基站，对于多个运营商共享使用的基站，该基站可以在系统消息中携带多个PLMN标识， 每个PLMN标识对应一个运营商。eNB通过系统消息(System Information Block 1，SIB1)广播N个PLMN ID时，UE接收到系统消息SIB1后，根据自己的用户身份识别模块(Subscriber Identity Module，SIM)卡，选择所需的PLMN ID。
示例性地，如图3中，基站通过系统消息广播PLMN1、PLMN2和PLMN3，UE1、UE2和UE3在接收到系统消息后，UE1选择接入PLMN1，UE2选择接入PLMN2，UE3选择接入PLMN3。
该步骤中，基于所需要支持的PLMN ID数量，创建对应数目的逻辑链路。OAM给基站下发P个源地址，基站对应设置P个对外传输的WAN口。
步骤102，向所述MME发送所述P条逻辑链路的配置信息，所述配置信息包括所述WAN口与所述MME的对应关系。
该步骤中，可通过无线资源控制(Radio Resource Control，RRC)信令向所述MME发送所述P条逻辑链路的配置信息。
示例性地，如图3中，假设有3个WAN口和3个MME，则可配置WAN口1对应MME1，WAN口2对应MME2，WAN口3对应MME3；或者，WAN口1对应MME2，WAN口2对应MME3，WAN口3对应MME1，或者其他一一对应关系。这里，基于不同的组合方式可知，共包括6种一一对应的关系。
步骤103，基于所述P条逻辑链路进行数据传输。
该实施例中，能够实现一个PLMN标识(Identifier，ID)对应一条逻辑链路，即，一个PLMN ID对应一个WAN口和一个MME，避免了在涉及多个PLMN ID，多个MME地址和多个源地址时，由于不清楚每个PLMN ID对应的WAN口和MME，导致存在操作上的不便的问题。
在一实施例中，上述步骤101，包括：
按照P个WAN口与P个MME的对应关系，创建P条数据链路和P条控制链路；所述控制链路和所述数据链路分别与所述WAN口为一一对应关系；所述控制链路和所述数据链路分别与所述MME为一一对应关系；
将对应同一MME的所述数据链路和所述控制链路均绑定到同一个WAN口上，得到所述P条逻辑链路；
将同一个PLMN ID下的S1接口、X2接口的控制面接口绑定到同一个控制链路上，以及将同一个PLMN ID下的S1接口、X2接口数据面接口绑定到同一个数据链路上，得到PLMN ID与P个逻辑链路的对应关系。
这里，S1接口是LTE基站(eNodeB)与分组核心网(Evolved Packet Core，EPC)之间的通讯接口。将LTE系统划分为无线接入网和核心网。X2接口是e-NodeB之间的互连接口，支持数据和信令的直接传输。
该实施例中，P个WAN口与P个MME为一一对应关系，且对应同一个对端MME的控制链路与数据链路绑定到同一个WAN口上，在同一个PLMN ID下的S1接口、X2接口的控制面接口统一绑定到相同的控制链路上，如PLMN ID1对应的控制链路1与数据链路1绑定到WAN口1上；将PLMN ID1下的S1接口、X2接口的控制面接口都绑定在控制链路1上，即对应WAN口1。类似，将S1接口、X2接口数据面接口都绑定到数据链路1上，同样对应WAN口1。如此，每个PLMN ID都对应有唯一的WAN口和唯一的MME，避免由于不清楚每个PLMN ID对应的WAN口和MME，导致存在操作上的不便的问题。
在一具体实施例中，所述按照P个WAN口与P个MME的对应关系，创建P条数据链路和P条控制链路，包括：
按照P个WAN口与P个MME的对应关系，协议栈控制面与P个MME建立P条相互隔离的流控制传输协议(Stream Control Transmission Protocol，SCTP)链路，并建立无线资源控制RRC与SCTP套接字(socket)绑定关系；其中，所述SCTP链路与所述WAN口为一一对应关系；所述SCTP链路与所述MME为一一对应关系；
按照P个WAN口与P个MME的一一对应关系，数据面建立P条相互隔离的数据链路，并建立用户平面部分(User Plane Part of GTP，GPTU)数据链路与用户数据报协议(User Datagram Protocol，UPD Socket)的绑定关系。
示例性地，假设本系统支持3个PLMN ID，协议栈控制面与对端MME按多链路(multi-homing)方式建立三条相互隔离的流控制传输协议(Stream Control Transmission Protocol，SCTP)链路；并建立RRC与SCTP socket绑定关系。同时按照由控制面RRC提供的源地址与对端服务器的对应关系，数 据面建立3条相互隔离的数据链路，并建立用户平面部分(User Plane Part of GTP，GPTU)数据链路与UPD Socket的绑定关系。其中，SCTP是一种可靠的传输协议，它在两个端点之间提供稳定、有序的数据传递服务，并且可以保护数据消息边界。
所谓Socket(套接字)，就是对网络中不同主机上的应用进程之间进行双向通信的端点的抽象。一个套接字就是网络上进程通信的一端，提供了应用层进程利用网络协议交换数据的机制。
在一实施例中，所述将对应同一MME的所述数据链路和所述控制链路均绑定到同一个WAN口上，得到所述P条逻辑链路之后，所述方法还包括：
为每条逻辑链路创建与对端安全网关的IP安全协议(IP Security，IPsec)隧道，并将对应的IPsec设置与逻辑链路进行绑定。
该实施例中，在建立好逻辑链路后，为了保证每条逻辑链路的安全，为每条逻辑链路创建与对端(MME端)安全网关的IPsec隧道，将对应的IPsec设置与逻辑链路进行绑定。
示例性地，创建逻辑链路绑定关系的配置如下：
在boardconf(基站平台配置)中的增加多个stackIPInterface(协议栈IP接口)配置，使用和wanConfig(WAN口配置)一样的方法，增加stackIPInterface2,stackIPInterface3，配置和stackIPInterface相同，具体如下：
Record name(配置项名称):stackIPInterface2；
Record ID(配置项ID):0x660a0002；
TR-069 Name(TR-069路径名称):boardconf.stack.stackIPInterface2；
Record name:stackIPInterface3；
Record ID:0x660a0003；
TR-069 Name:boardconf.stack.stackIPInterface3。
绑定关系见下表：

示例性地，创建IPsec安全隧道的配置如下：
在boardconf中增加tunnelConfigX(第X个tunnel配置)，其中的配置项和tunnelConfig1完全相同，例如在boardconf中增加一个tunnelConfig3，具体如下：
Record name:tunnelConfig3；
Record ID:0x66040005；
TR-069 Name:boardconf.ipsec.tunnelConfig3。
在一实施例中，上述方法还包括：将各个PLMN ID下的所有链路设置统一的控制接口，并连接控制中心。
上述方案中，通过创建逻辑链路，将同属于一个运营商PLMN ID下的多接口绑定在一条逻辑链路上，优化了基站内部管理，增加接口间的隔离度，提高链路的稳定性，通过绑定IPsec隧道，进一步提高系统的安全性。提高了网络共享的应用场景灵活性、广泛性、稳定性、安全性。
