场景三、在发生地震或紧急情况，蜂窝网络无法正常工作的情况下，允许设备间直接通信，如图1中的模式3，UE5、UE6和UE7相互间的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。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
图2是根据本发明实施例的资源的获取方法的流程图。如图2所示，该资源的获取方法可以包括以下处理步骤：
步骤S202：源节点向目标节点发送与UE的D2D服务质量对应的信息集合，其中，信息集合用于目标节点为UE配置/分配D2D资源和/或调制编码方式。
根据现有3GPP标准会议的进展，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。而第二资源分配方式由基站根据UE的请求为UE分配合适的D2D资源。针对第一资源分配方式，系统允许为一个UE配置多个与第一资源分配方式对应的资源池。但是，对于基站以及用户设备选择何种资源池进行D2D传输，相关技术中并未给出系统、完善的解决方案。针对第二资源分配方式，如何能够在切换时确保D2D的服务质量也尚未见到相关解决方案。采用如图2所示的方法，源节点(例如：基站)可以根据与UE的D2D服务质量对应的信息集合为UE配置合适的资源。由此，解决了相关技术中无法确保D2D UE的D2D服务质量的问题，进而可以快速、灵活地为UE分配或配置合适的D2D资源，确保D2D传输的顺利进行。

下面将结合以下多个优选实施方式对上述优选实施过程作进一步的描述。
优选实施例一
在该优选实施例中，提供了基站以及UE根据UE D2D服务质量信息选择资源池的过程。以下将通过具体实例1和具体实例2做进一步地详细阐述。
实例1
在公共安全场景下，Officer A、B、C、D使用具备D2D功能的公共安全UE1、UE2、UE3以及UE4。Officer A、B、C、D均订阅了公共安全服务，并且UE1、UE2、UE3均配置属于D2D通信组X。
在救援地点，Officer A希望发起组播通话，告知附近对应于D2D通信组X的其他Officer相关信息。图5是根据本发明优选实施例一中实例1的用户设备D2D服务质量信息获取及通过专有信令获取D2D资源池的配置流程图。如图5所示，该流程可以包括以下处理步骤：
步骤S502：Officer A的UE1首先需要接入网络，从邻近服务功能(ProSe function)获取用户设备优先级和/或用户设备所属D2D通信组优先级，用户设备类型和/或D2D通信组类型，通信范围类型等信息。此外，用户设备还可以从ProSe function获取用户设备/D2D通信组D2D聚合最大数据率和/或对应于目标用户设备或D2D通信组的D2D承载服务质量参数列表。
步骤S504：UE1向服务基站eNB发送包含目标通信节点，例如：将D2D通信组X的标识信息，D2D通信组X的索引信息，D2D通信组X的优先级，用户设备类型，通信范围类型等信息，D2D聚合最大数据率和/或对应于目标D2D通信组X的D2D承载服务质量参数列表至基站eNB。
步骤S506：eNB接收到UE1发送的上述信息后，可以根据用户设备的D2D服务质量相关信息为用户设备选择可配置的D2D资源池，例如：如果UE1的目标通信D2D通信组X的优先级为高，则eNB为UE1配置用于高优先级D2D通信组使用的D2D发送资源池；如果UE1的通信范围类型为短距离，则eNB为UE1选择用于短距离D2D用户设备使用的D2D发送资源池；如果UE1的类型为中继节点，则eNB为UE1配置用于中继通信的D2D发送资源池。除此之外，eNB还可以根据用户设备的承载服务质量参数判断是否能够为UE分配足够的第二资源分配方式的资源，进行接纳控制，如果有足够的资源，则可以为UE1配置第二资源分配方式。然后，eNB可以通过专有信令向UE1发送包含D2D服务质量相关信息的D2D资源配置信息。
UE1在接收到D2D资源配置信息后，可以根据户设备当前的状态选择与D2D服务质量相关信息匹配的D2D资源池进行D2D传输。
除了上述UE1主动向eNB上报用户设备的D2D服务质量相关信息之外，eNB还可以从MME以及ProSe function通过初始上下文建立请求(Initial context setup request) 消息以及D2D承载的建立消息获取/修改/释放消息获取用户设备的D2D服务质量相关信息，用于后续用户设备资源配置。
实例2
在商业应用场景下，Mary和John持有具备D2D发现功能的UE1和UE2。UE1和UE2彼此在D2D发现范围内。图6是根据本发明优选实施例一中实例2的用户设备通过广播信令获取D2D资源池配置流程图。如图6所示，该流程可以包括以下处理步骤：
步骤S602：处于闲置态的UE1和UE2如果需要进行D2D发现，首先需要监听驻留小区是否广播D2D发送资源池信息。假设驻留小区对应的eNB广播发送第一资源分配方式对应的资源池信息。如果第一资源分配方式对应的资源池存在多个，则eNB1可以根据用户设备优先级和/或应用优先级，用户设备类型和/或应用类型，覆盖范围，发现范围类型等不同属性划分不同的第一资源分配方式对应的发送资源池，并广播发送每个资源池对应的上述属性信息。属性信息可统一通过使用索引或是属性列表指示。使用索引可以是一个bitmap或是数组，按照某种规则指示适用的一个或多个属性信息，例如：优先级、类型、覆盖范围以及发现范围属性。以5bit的bitmap为例，可以使用索引如高两比特指示可以使用该资源池的D2D UE的优先级，接着一个bit指示可使用该资源池的用户设备是公共安全设备还是非公共安全设备，最后两个bit指示可使用该资源池的用户设备对应的发现范围类型。
需要说明的是，上述优选实施例中提供的使用索引仅为一种优选实施方式，其并不构成对本发明的不当限制，实际的使用索引可以是任意长度的bitmap，使用预定义的属性指示规则进行编码。
步骤S604：UE1和UE2接收到eNB广播发送的D2D发送资源池信息，然后，再根据用户设备优先级和/或应用优先级，用户设备类型和/或应用类型，发现范围类型等属性信息选择与D2D服务质量相关信息匹配的D2D资源池进行D2D发现消息的发送。
具体的，UE1可判断自身的用户设备的优先级，如果是高优先级，则选择基站发送的资源池的属性对应于高优先级用户设备的D2D资源池；其次判断用户设备的类型，如果是公共安全用户设备，则选择基站发送的资源池的属性对应于公共安全用户设备的D2D资源池；最后判断用户设备的发现范围类型，如果是短范围，则选择基站发送的资源池的属性对应于短发现范围的D2D资源池。类似的，D2D通信组/应用优 先级，D2D通信组/应用类型，覆盖范围，D2D通信组索引映射可以采用类似的方式进行判断。需要说明的是，如果基站广播发送的D2D资源池的属性信息包括D2D发现目标标识映射索引，则UE将计划发现的D2D目标UE或D2D组标识根据某种预定规则取模后，将得到的值与D2D资源池对应的D2D发行目标映射索引相比较，如果相同则选择该D2D资源池。类似的，D2D通信可以采用相似的方式进行D2D资源池选择。
如果UE根据自身的多个属性找不到满足所有条件的D2D发送资源池，则UE可根据自身实现或是系统预定义的属性判断顺序，优选满足一个或多个高优先级属性判断条件的D2D资源池。此外如果有多个D2D资源池同时满足UE的判断条件，则UE可监听多个资源池的资源占用情况(通过监听发现周期内发现资源占用情况，如果是D2D通信，则可监听SA周期内的SA资源占用情况)，之后选择负荷较轻的D2D资源池进行D2D发送。
优选实施例二
在该优选实施例中，提供了用户设备切换时D2D服务质量信息的传递过程。以下将通过实例3至实例5做进一步的详细阐述。

在救援地点，Officer A希望发起组播通话，告知附近对应于D2D通信组X的其他Officer相关信息。Officer A的UE1使用上述实例1中描述的方法获得了eNB1下发的D2D资源配置信息，并开始D2D传输。图7是根据本发明优选实施例二中实例3的用户设备X2切换D2D服务质量信息传递流程图。如图7所示，该流程可以包括以下处理步骤：
步骤S702：假设Officer A处于移动状态，其服务基站eNB1根据UE1的测量上报判断UE1需要进行蜂窝切换，则源基站eNB1为UE1选择合适的目标基站eNB2，并向eNB2发送包含D2D服务质量信息的切换请求消息。切换请求消息中用户设备的D2D服务质量相关信息可以包括：用户设备优先级和/或D2D通信组优先级，用户设备类型和/或D2D通信组类型，用户设备/D2D通信组/的通信范围类型，D2D通信目 标标识(即D2D通信组X的标识)，用户设备D2D聚合最大数据率和/或D2D通信组聚合最大数据率。此外还可以包含对应于D2D通信组X的D2D承载服务质量参数列表，其中，可以包含：D2D承载/逻辑信道标识、服务质量类型标识、分配和保留优先级、最大发送和/或接收比特率、保证发送和/或接收比特率等信息。
步骤S704：目标基站eNB2接收到UE1的D2D服务质量相关信息后，根据用户设备D2D服务质量相关信息判断所需要的D2D资源，进行接纳控制，并向源中央节点发送允许接纳的对应于D2D通信组X的D2D承载信息。目标eNB2还可以根据用户设备D2D服务质量相关信息以及允许接纳的对应于D2D通信组X的D2D承载为用户设备在目标小区进行D2D资源配置，并通过切换请求确认消息发送至源基站eNB1。

步骤S802：假设Officer A处于移动状态，其服务基站eNB1根据UE1的测量上报判断UE1需要进行蜂窝切换，则源基站eNB1为UE1选择合适的目标基站eNB2，并向eNB2发送包含D2D服务质量信息的切换请求消息。假设eNB1和eNB2之间没有X2连接，则eNB1可以向MME发送切换请求消息。切换请求消息中用户设备的D2D服务质量相关信息包括用户设备优先级和或D2D通信组优先级，用户设备类型和或D2D通信组类型，用户设备/D2D通信组/的通信范围类型，D2D通信目标标识(即D2D通信组X的标识)，用户设备D2D聚合最大数据率和或D2D通信组聚合最大数据率。此外还可包含对应于D2D通信组X的D2D承载服务质量参数列表，其中包含D2D承载/逻辑信道标识、服务质量类型标识、分配和保留优先级、最大发送和或接收比特率、保证发送和或接收比特率等信息。
