具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白，以下举实施例并参照附图，对本发明进一步详细说明。
D2D技术可以工作在授权频段或非授权频段，允许多个支持D2D功能的用户设备即D2D用户设备(D2DUE，D2DUser Equipment)在有网络基础设施或无网络基础设施的情况下进行直接发现/直接通信。D2D的应用场景主要有以下三种：
1)UE1和UE2在蜂窝网络的覆盖下进行数据交互，用户面数据不经过网络基础设施，如图1所示的模式1；
2)在弱/无覆盖区域的UE中继传输，如图1中所示的模式2，允许信号质量较差的UE4通过附近有网络覆盖的UE3与网络进行通信，能帮助运营商扩展覆盖、提高容量；
3)在发生地震或紧急情况，蜂窝网络不能正常工作的情况下，允许设备间直接通信，如图1中所示的模式3，UE5、UE6和UE7间控制面和用户面都不经过网络基础设施而进行一跳或多跳的数据通信。
D2D技术通常包括D2D发现技术和D2D通信技术：D2D发现技术是指用于判断/确定两个或多个D2D用户设备之间相互邻近(例如在可进行D2D直接通信范围之内)或用于判断/确定第一用户设备邻近第二用户设备的技术。通常，D2D用户设备间可通过发送或接收发现信号/信息来发现对方，在有蜂窝网络覆盖的情况下，网络可辅助D2D用户设备进行D2D发现；D2D通信技术是指D2D用户设备之间部分或全部通信数据可以不通过网络基础设施而直接进行通信的技术。
网络共享是指多个运营商共享通用移动通信***地面无线接入网，现有技术中支持多PLMN场景(Multiple PLMN)，例如对于单个UE来说，UE可以驻留在多个网络中，其支持的公共陆地移动网络(PLMN，Public Land Mobile Network)列表，称为对等PLMN列表(EPLMN list，Equivalent PLMN list)，这些可以由签约信息约定。而与UE的国际移动用户标识(IMSI，International Mobile Subscriber Identity)中的国家码(MCC)和区域码(MNC)构成的PLMN相同的PLMN称为该UE的归属PLMN(HPLMN，Home PLMN)。
图2为本发明实施例的基于网络共享的设备到设备的通信方法的流程图，如图2所示：本发明实施例中的基于网络共享的设备到设备的通信方法包括以下步骤：
步骤201：eNB获取D2D运营商的资源使用的信息，并为参与网络共享的D2D运营商分配各自的发现资源池和各自的通信资源池。
步骤202：eNB通过广播(SIB)消息或专用消息通知不同运营商服务的D2D UE其所使用的D2D发现资源池信息和其所使用的D2D通信的资源池信息。
上述广播消息中包括多个运营商的信息，多个运营商的信息具体表现为一个或多个PLMN ID。
上述广播消息包括D2D资源池的时、频、码信息。
D2D通信和D2D发现可以使用不同的资源池信息。
eNB为不同运营商分配不同的D2D发现和D2D通信的资源池。
资源池可以包括为调度分配(SA)资源池、发送资源池、接收资源池等。
eNB分配D2D UE发送D2D发现信令时使用的无线资源时，为不同PLMN分配对应的D2D资源。
eNB可以在D2D UE进行初始接入时记录D2D UE和其服务运营商的PLMN ID的对应关系。
基站查找D2D UE的服务PLMN对应的发现资源池，并为该D2D UE分配无线资源。或者，如果D2D UE请求接入时已经携带或者隐含了自身当前的服务的PLMN，那么，eNB只需要查找该UE的服务PLMN对应的发现资源池，并为该D2D UE分配无线资源。
如果D2D UE竞争获取资源，D2D UE发送D2D发现信令和/或通信信令和/或通信数据时，D2D UE从当前服务PLMN或对等PLMN下所对应的D2D发现资源池中分配无线资源。
步骤203：不同运营商服务的D2D UE使用上述资源池的信息，进行D2D发现和D2D通信，实现D2D技术下的网络共享。
针对D2D发现场景，步骤203可以包括三个子步骤：
子步骤1：D2D UE获取其D2D服务运营商，以及，可以和那些运营商进行D2D发现的运营商列表。
子步骤2：D2D UE根据包含D2D发现资源池信息的广播消息，和可以进行D2D发现的运营商列表信息，确定D2D UE在D2D发现过程中其要监听的D2D发现信号的资源范围。
子步骤3：根据服务运营商分配D2D UE发送D2D发现信令时使用的无线资源。
针对该场景的子步骤3有两种方法，方法一，是由eNB分配无线资源，方法二是由D2D UE自身分配无线资源。
针对D2D通信场景，步骤203又可以包括如下三个子步骤：
子步骤1：D2D UE获取其D2D服务运营商，以及可以和那些运营商进行D2D通信的运营商列表。
子步骤2：D2D UE根据包含D2D发现资源池信息的广播消息，和可 以进行D2D通信的运营商列表信息，确定其在D2D通信过程中其要接收的D2D发现信号的资源范围。
子步骤3：D2D UE根据服务运营商分配D2D UE发送D2D通信信令和通信数据时使用的无线资源。
在网络共享下实现D2D技术的场景，还包括基站广播相邻小区资源池信息的场景。
以下将通过具体示例，进一步阐明本发明技术方案的实质。
实施例一

eNB根据参与网络共享的D2D运营商的PLMN ID，在D2D通信的总的资源池内为每个D2D运营商划分用于D2D通信的资源池。
eNB根据参与网络共享的D2D运营商的PLMN ID，在D2D发现的总的资源池内为每个D2D运营商划分用于D2D发现的资源池。
eNB通过广播消息通知不同运营商服务的D2D UE其所使用的D2D发现资源池信息和其所使用的D2D通信的资源池信息。
eNB新增了一个SIB消息，该SIB消息的格式如表1所示：
Figure PCTCN2015083911-appb-000001
该SIB消息包括网络共享的D2D运营商的PLMN ID，每个PLMN ID下包括两个D2D参数表，一个D2D通信资源池参数表，一个D2D发现资源池参数表，每个参数表都从时，频，码三个方面，定义资源池的资源范围。
不同运营商服务的D2D UE使用上述资源池的信息，进行D2D发现，实现D2D技术下的网络共享。
步骤301，D2D鉴权的过程中，D2D UE获取其服务运营商的PLMN ID，同时还获取可以和该运营商进行D2D发现的D2D运营商的PLMN ID。
步骤302，在鉴权过程中eNB生成D2D UE和其服务运营商的PLMN ID的对应关系。
步骤303，eNB通过SIB消息广播共享运营商的发现资源池信息和通信资源池的信息。
步骤304，D2D UE接收eNB发送的广播消息，首先根据自身的服务运营商的PLMN ID从广播消息中查找该PLMN ID对应的D2D发现资源池的资源范围。然后在根据可以和其服务运营商进行D2D发现的运营商的PLMN ID，并从广播消息中查找这些PLMN ID对应的D2D发现资源池的 资源范围。D2D UE在这些资源范围内监听发现信号。
步骤305，D2D UE中的通告D2D UE在发送D2D发现消息之前，向eNB发送资源分配请求消息。
步骤306，eNB收到该消息之后，根据D2D UE的信息，确定其服务运营商，eNB在该D2D UE的服务运营商对应的资源池内为期分配无线资源。
步骤307，eNB向D2D UE中的通知D2D UE发送资源分配响应消息。
步骤308，D2D UE中的通知D2D UE收到该消息后，在eNB分配的资源上发送D2D发现消息。D2D UE中的监听用户设备监听该消息，完成D2D发现流程。
本发明实施例中，根据D2D资源进行D2D发现及D2D通信是容易实现的，由于并非本发明实施例的重点，因此不再赘述其详细流程。
实施例二
本实施例给出了D2D技术下实现网络共享，实现D2D发现的具体实施例，在本实施例中，由eNB分配发送D2D发现信令时使用的无线资源。和实施例一不同的是，本方法是D2D UE中的通知用户设备，在发资源分配请求时，携带自身服务运营商的信息。
eNB为参与网络共享的D2D运营商分配各自的发现资源池和各自的通信资源池。
eNB根据参与网络共享的D2D运营商的PLMN ID，在D2D通信的总的资源池内为每个D2D运营商划分用于D2D通信的资源池。
