当所述D2D UE的RRC连接建立成功时，所述D2D UE与基站进行交互、获得所述基站分配的专用的D2D发送资源信息；当所述D2D UE的RRC连接建立不成功时，确定所述D2D UE处于异常情况，所述D2D UE从系统广播消息中接收所述D2D资源池配置信息，从所述D2D资源池配置信息中获取D2D资源池信息，根据所述D2D资源池信息竞争获取D2D发送资源进行D2D发送。
其中，所述D2D UE从系统广播消息中接收所述D2D资源池配置信息，从所述D2D资源池配置信息中获取D2D资源池信息，根据所述D2D资源池信息竞争获取D2D发送资源进行D2D发送，包括：若D2D UE接收的所述D2D资源池配置信息中包含的RRC状态信息为空闲态，则D2D UE只能在处于IDLE态时使用所述RRC状态信息关联的D2D资源池信息；若D2D UE接收的所述D2D资源池配置信息中包含的RRC状态信息为连接态，则D2D UE只能在处于连接态时使用所述RRC状态信息关联的D2D资源池信息。
或者，所述D2D UE从所述D2D资源池配置信息中获得D2D发送资源，并进行D2D发送，还可以包括：
若处于连接态的D2D UE从系统广播消息或RRC专有信令中接收的所述D2D资源池配置信息中包含有效定时器，则处于连接态的D2D UE进入异常情况后开启所述有效定时器，并在所述有效定时器生效期间使用从配置所述有效定时器的小区中接收的D2D资源池进行D2D发送；所述从配置所述有效定时器的小区中接收的D2D资源池可由D2D UE通过RRC专有信令或系统广播消息接收；
若处于IDLE态的D2D UE从系统广播消息中接收的所述D2D资源池配置信息中包含有效定时器，则处于IDLE态的D2D UE进入异常情况后开启所述有效定时器，并在所述有效定时器生效期间使用与所述有效定时器关联的D2D资源池进行D2D发送；
若处于IDLE态的D2D UE从系统广播消息中接收的所述D2D资源池配置信息中包含有效定时器，则处于IDLE态的D2D UE通过系统广播消息接收D2D资源池信息后，若所述D2D UE发生小区重选，则开启所述有效定时器，并在所述有效定时器生效期间使用所述与所述有效定时器关联的D2D资源池进行D2D发送。
其中，所述连接态D2D UE的异常情况包括：T301或T311生效；或者，服务小区参考信号接收功率低于特定门限值；所述特定门限值由D2DUE通过系统广播消息或RRC专有信令从基站获取。

当D2D UE接收的所述D2D资源池配置信息中包含的RRC状态信息为连接态时，D2D UE确定在处于连接态时使用所述D2D资源池配置信息中的D2D资源池信息；
当D2D UE接收的所述D2D资源池配置信息中包含的使用条件为蜂窝网络覆盖内使用时，D2D UE确定处于蜂窝网络覆盖内时使用所述D2D资源池配置信息中的D2D资源池信息；

本实施例中所述的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D2D用户设备(D2D User Equipment，D2D UE)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2的模式1；
2)在弱/无覆盖区域的UE中继传输，如图2中的模式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2中的模式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：
1)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。
2)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。
D2D UE在进行D2D发现或D2D通信之前，都需要首先获取相应的无线资源，无论是D2D发现还是D2D通信资源，都存在两种资源分配方式，即基于竞争的资源获取(第一资源分配方式)或是由基站为UE分配专有的资源(第二资源分配方式)进行D2D发现/通信。第一资源分配方式通常由基站或是系统预分配一个D2D资源池，参与D2D发现/通信的D2D UE监听该资源池，并通过竞争的方式获取D2D发送资源，这种方式主要用于蜂窝网络覆盖外的D2D UE，也可用于蜂窝网络覆盖内的D2D UE。对于蜂窝网络覆盖内的D2D UE，其可使用所服务小区配置的D2D竞争资源池。对于蜂窝网络覆盖外的D2D UE，则可使用预配置的D2D竞争资源池。而第二资源分配方式由基站根据D2D UE的请求为D2D UE分配合适的D2D资源，这种方式只能用于位于蜂窝网络覆盖内的D2D UE。
可见，采用本发明提供的方案，能使得D2D UE在无法从基站获取专用资源时，也能及时使用基于竞争的资源获取方式获得D2D发送资源，进而保证D2D业务的服务连续性，提升D2D业务服务质量和用户体验。
实施例二、
本发明实施例提出一种D2D资源池配置方法，应用于基站中，包括：所述基站发出D2D资源池配置信息；使得接收到所述D2D资源池配置信息的D2D UE从所述D2D资源池配置信息中获得D2D发送资源，并进行D2D发送。
这里，所述D2D资源池配置信息包括以下之一或组合：D2D资源池信息、D2D资源池使用条件、RRC状态信息、有效定时器。
其中，所述D2D资源池信息包括：D2D发现资源池信息、和/或D2D通信资源池信息、和/或D2D通信SA资源池信息、和/或D2D通信数据资源池信息；
所D2D资源池使用条件包括：受限使用，或无受限使用；所述受限使用为异常情况下使用，或蜂窝网络覆盖内使用，或蜂窝网络覆盖外使用；
所述RRC状态信息指示可使用所述D2D资源池信息的UE所处的RRC状态，包括：连接态，或空闲态，或连接态和空闲态。
所述D2D UE通过以下方式从基站接收D2D资源池配置信息：系统广播消息；和/或，RRC专有信令。
本实施例中所述的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D2D用户设备(D2D User Equipment，D2D UE)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2的模式1；
2)在弱/无覆盖区域的UE中继传输，如图2中的模式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2中的模式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：
1)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。
2)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。
D2D UE在进行D2D发现或D2D通信之前，都需要首先获取相应的无线资源，无论是D2D发现还是D2D通信资源，都存在两种资源分配方式，即基于竞争的资源获取(第一资源分配方式)或是由基站为UE分配专有的资源(第二资源分配方式)进行D2D发现/通信。第一资源分配方式通常由基站或是系统预分配一个D2D资源池，参与D2D发现/通信的D2D UE监听该资源池，并通过竞争的方式获取D2D发送资源，这种方式主要用于蜂窝网络覆盖外的D2D UE，也可用于蜂窝网络覆盖内的D2D UE。对于蜂窝网络覆盖内的D2D UE，其可使用所服务小区配置的D2D竞争资源池。对于蜂窝网络覆盖外的D2D UE，则可使用预配置的D2D竞争资源池。而第二资源分配方式由基站根据D2D UE的请求为D2D UE分配合适的D2D资源，这种方式只能用于位于蜂窝网络覆盖内的D2D UE。
可见，采用本发明提供的方案，能使得D2D UE在无法从基站获取专用资源时，也能及时使用基于竞争的资源获取方式获得D2D发送资源，进而保证D2D业务的服务连续性，提升D2D业务服务质量和用户体验。
实施例三、
本实施例描述的是基站发送的系统广播消息包含D2D资源池使用条件的D2D资源池配置信息的方法，如图3所示，包括以下步骤：
步骤301：基站通过系统广播消息(SIB)发送D2D资源池配置信息；其中，所述D2D资源池配置信息包括D2D资源池信息及D2D资源池使用条件。
这里，所述D2D资源池信息包括D2D发现资源池信息和/或D2D通信资源池信息和/或D2D通信SA资源池信息和/或D2D通信数据资源池信息；D2D资源池使用条件为异常情况下使用或通用。
步骤302：处于IDLE态的D2D UE接收到所驻留小区SIB，从所述SIB中获取D2D资源池配置信息。
假设该D2D UE想要执行D2D发现或D2D通信的发送，若所接收的D2D资源池使用条件为通用，则该D2D UE可以不发起RRC连接建立流程，并在IDLE态下使用所驻留小区SIB中广播的D2D资源池采用基于竞争的资源获取方式执行D2D发现或D2D通信的发送。
可选的，若该D2D UE想要使用基站分配的专用资源，则发起RRC连接建立流程。
步骤303：所述D2D UE从所述资源池配置信息中获取资源池使用条件，当所述D2D资源池使用条件为异常情况下使用时，所述D2D UE发起RRC连接建立流程。
进一步地，所述D2D UE发起RRC连接建立流程后，若RRC连接建立成功，则该UE可通过RRC专有信令获取基站分配的非竞争专用资源用于D2D发现或D2D通信的发送。或者UE可通过RRC专有信令从基站获取D2D资源池信息，并采用基于竞争的资源获取方式执行D2D发现或D2D通信的发送。
若RRC连接建立不成功，可包括以下情况：
1)UE没有通过接入等级检查access barring check；
2)收到RRC连接拒绝消息；
3)T300,T302,T303,T305或T306运行时发生小区重选；
4)T300超时；
则该UE认为其处于异常情况，使用其从所驻留小区的SIB中获取的D2D资源池采用基于竞争的资源获取方式执行D2D发现或D2D通信的发送。
可选的，该UE可在经历一次或N次RRC连接建立失败后，认为其处于异常情况，其中N值可以为默认值，或者由基站通过RRC专有信令或系统广播消息配置给UE。
若该UE后续成功完成RRC连接建立流程，则可从基站处通过RRC专有信令获取专用资源用于D2D发送。
实施例四、
本实施例描述的是基站发送的D2D资源池配置信息包含RRC状态信息的方法，如图4所示，包括以下步骤：
步骤401：基站通过SIB或RRC专有信令发送D2D资源池配置信息；其中，所述D2D资源池配置信息包括D2D资源池信息及RRC状态信息。
这里，所述D2D资源池信息包括D2D发现资源池信息和/或D2D通信资源池信息和/或D2D通信SA资源池信息和/或D2D通信数据资源池信息；
其中RRC状态信息指示可使用所述D2D资源池信息的UE所处的RRC状态，包括：连接态，或空闲态，或连接态和空闲态。
步骤402：D2D UE通过SIB或RRC专有信令接收所驻留小区或服务小区发送的D2D资源池配置信息，所述D2D UE从所述D2D资源池配置信息中获得D2D发送资源，并进行D2D发送。
其中，所述D2D UE从所述D2D资源池配置信息中获得D2D发送资源，并进行D2D发送可以包括以下场景：
场景一、若所接收的RRC状态信息为连接态，则UE只能在处于RRC 连接态时使用该D2D资源池信息。若处于IDLE态的UE想要执行D2D发送，需发起RRC连接建立流程尝试进入连接态；而处于CONNECTED态的UE可使用该D2D资源池进行D2D发送，若该UE进入IDLE态，则停止使用该只能用于CONNECTED态的D2D资源池。
场景二、若所接收的RRC状态信息为空闲态，则UE只能在处于RRC空闲态时使用该D2D资源池信息。也即，IDLE态UE不需要进入连接态便可使用其从所驻留小区SIB接收的D2D资源池信息。一旦该UE进入RRC连接态，则停止使用只能用于空闲态的D2D资源池信息，而是通过RRC专有信令从基站获取专用资源或竞争资源池。若处于CONNECTED态的UE接收到该只能用于空闲态的D2D资源池信息，则该UE处于连接态时不能使用该D2D资源池信息，而是向基站请求D2D专有资源。该UE进入IDLE态后可使用该只能用于空闲态的D2D资源池信息。
场景三、若所接收的RRC状态信息为连接态和空闲态，则对应的D2D资源池信息可用于空闲态，也可用于连接态。
实施例五、
本实施例描述的是基站通过RRC专有信令发送的D2D资源池配置信息包含有效定时器信息的方法，如图5所示，该方法包括以下步骤：
步骤501：基站通过RRC专有信令发送D2D资源池配置信息给D2DUE，其中包括D2D资源池信息，D2D资源池使用条件及有效定时器。
其中D2D资源池信息包括D2D发现资源池信息和/或D2D通信资源池信息和/或D2D通信SA资源池信息和/或D2D通信数据资源池信息；其中D2D资源池使用条件为异常情况下使用。
步骤502：处于连接态的D2D UE通过RRC专有信令接收服务小区发送的上述D2D资源池配置信息，其中包括D2D资源池信息，D2D资源池使用条件及有效定时器。若该UE判断自身处于异常情况，则开启有效定时 器，并在有效定时器生效期间使用上述D2D资源池配置信息中的D2D资源池信息进行D2D发送。若在有效定时器生效期间UE成功从基站处获得D2D专用资源，则可停止该有效定时器，使用D2D专用资源进行D2D发送。
具体的，UE可根据以下准则判断自身处于异常情况：
1)T301或T311生效；
2)服务小区参考信号接收功率低于特定门限值；该特定门限值可由D2D UE通过系统广播消息或RRC专有信令从基站获取。
实施例六、
本实施例描述的是基站通过系统广播消息发送的D2D资源池配置信息包含有效定时器信息的方法之一，如图6所示，该方法包括以下步骤：
步骤601.基站通过系统广播消息发送D2D资源池配置信息给D2DUE，其中包括D2D资源池信息，D2D资源池使用条件及有效定时器。
其中D2D资源池信息包括D2D发现资源池信息和/或D2D通信资源池信息和/或D2D通信SA资源池信息和/或D2D通信数据资源池信息；其中D2D资源池使用条件为异常情况下使用。
步骤602.处于空闲态的D2D UE通过系统广播消息接收服务小区发送的上述D2D资源池配置信息；其中包括D2D资源池信息，D2D资源池使用条件及有效定时器，其中D2D资源池使用条件为异常情况下使用。
若该D2D UE进行D2D发送，则发起RRC连接建立流程尝试建立RRC连接。若RRC连接建立成功，则该UE可通过RRC专有信令获取基站分配的非竞争专用资源用于D2D发现或D2D通信的发送。或者UE可通过RRC专有信令从基站获取D2D资源池信息，并采用基于竞争的资源获取方式执行D2D发现或D2D通信的发送。若RRC连接建立不成功，可包括以下情况：
1)UE没有通过接入等级检查access barring check，开启Tbarring定时 器
2)收到RRC连接拒绝消息；
3)T300,T302,T303,T305或T306运行时发生小区重选；
4)T300超时；
则该UE认为其处于异常情况，开启有效定时器，并在有效定时器生效期间使用上述从SIB中接收的D2D资源池配置信息中的D2D资源池信息进行D2D发送。可选的，该UE可在经历一次或N次RRC连接建立失败后，认为其处于异常情况，其中N值可以为默认值，或者由基站通过RRC专有信令或系统广播消息配置给UE。若在有效定时器运行期间该UE后续成功完成RRC连接建立流程并从基站处获得D2D专用资源，则可停止该有效定时器，使用D2D专用资源进行D2D发送。
实施例七、
本实施例描述的是基站通过系统广播消息或RRC专用消息发送的D2D资源池配置信息包含有效定时器信息的方法之二，如图7所示，该方法包括以下步骤：

步骤702.处于空闲态或连接态的D2D UE通过系统广播消息或RRC专用消息接收上述D2D资源池配置信息。
针对空闲态UE，若该UE发生小区重选或检测到其处于无网络覆盖状态，则开启有效定时器，并在有效定时器生效期间使用上述从SIB或RRC 专有信令中接收的D2D资源池配置信息中的D2D资源池信息进行D2D发送。若在有效定时器运行期间该UE重新从基站处获得新的D2D资源池配置信息，则可停止该有效定时器，并使用新的D2D资源池配置信息进行D2D发送。
针对连接态UE，若该UE发生小区切换(或接收到切换命令消息)或检测到其处于无网络覆盖状态，则开启该有效定时器，并在有效定时器生效期间使用上述从SIB或RRC专有信令接收的D2D资源池配置信息中的D2D资源池信息进行D2D发送。若在有效定时器运行期间该UE重新从基站处获得新的D2D资源池配置信息或D2D专用资源，则可停止该有效定时器，使用新的D2D资源池配置信息或D2D专用资源进行D2D发送。

或者，所述接收单元，具体用于处于连接态的D2D UE从系统广播消息或RRC专有信令中接收的所述D2D资源池配置信息；
相应的，所述处理单元，具体用于所述D2D资源池配置信息中包含有效定时器，则处于连接态的D2D UE进入异常情况后开启所述有效定时器，并在所述有效定时器生效期间使用从配置所述有效定时器的小区中接收的D2D资源池进行D2D发送；或者，在所述有效定时器生效期间使用与所述有效定时器关联的D2D资源池进行D2D发送；或者，在所述有效定时器生效期间使用所述与所述有效定时器关联的D2D资源池进行D2D发送。
其中，所述连接态D2D UE的异常情况包括：T301或T311生效；或者，服务小区参考信号接收功率低于特定门限值；所述特定门限值由D2DUE通过系统广播消息或RRC专有信令从基站获取。

本实施例中所述的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D2D用户设备(D2D User Equipment，D2D UE)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2的模式1；
2)在弱/无覆盖区域的UE中继传输，如图2中的模式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2中的模式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 UE在进行D2D发现或D2D通信之前，都需要首先获取相应的无线资源，无论是D2D发现还是D2D通信资源，都存在两种资源分配方式，即基于竞争的资源获取(第一资源分配方式)或是由基站为UE分配专有的资源(第二资源分配方式)进行D2D发现/通信。第一资源分配方式通常由基站或是系统预分配一个D2D资源池，参与D2D发现/通信的D2D UE监听该资源池，并通过竞争的方式获取D2D发送资源，这种方式主要用于蜂窝网络覆盖外的D2D UE，也可用于蜂窝网络覆盖内的D2D UE。对于蜂窝网络覆盖内的D2D UE，其可使用所服务小区配置的D2D竞争资源池。对于蜂窝网络覆盖外的D2D UE，则可使用预配置的D2D竞争资源池。而第二资源分配方式由基站根据D2D UE的请求为D2D UE分配合适的D2D资源，这种方式只能用于位于蜂窝网络覆盖内的D2D UE。
