作为一种实施方式，所述终端基于第二类信息确定业务等级信息，包括：所述终端对所述第二类信息包括的信息进行加权求和处理，确定初始业务等级；所述终端基于所述初始业务等级和预设的业务等级中的最大值 确定业务等级信息。
作为一种示例，若第二类信息包括业务数据的传输速率、业务数据的压缩编码方式、业务数据的紧急程度、业务数据的清晰度，则针对第二类信息中的每个信息预先配置权重值，如业务数据的传输速率的权重值为a2，业务数据的压缩编码方式的权重值为b2，业务数据的紧急程度的权重值为c2，业务数据的清晰度的权重值为d2，则初始业务等级可通过以下表达式表示：
初始业务等级＝a2*业务数据的传输速率+b2*业务数据的压缩编码方式+c2*业务数据的紧急程度+d2*业务数据的清晰度。
而终端中预先获得或预先配置业务对应的业务等级，终端将获得的初始业务等级与预设的业务等级进行比较，获得比较结果的最大值，取该最大值作为业务等级信息。
作为一种示例，业务等级信息(可记为V-QoS)可通过以下表达式表示：
V-QoS＝max{a2*业务数据的传输速率+b2*业务数据的压缩编码方式+c2*业务数据的紧急程度+d2*业务数据的清晰度，Qos等级}。
本实施例中，终端基于获得的所述终端的能力信息和/或业务等级信息确定第一同步源优先级信息，以及发送第一同步源优先级信息。这里，所述第一同步源优先级信息包括所述终端的能力信息和/或业务等级信息。作为一种实施方式，所述第一同步源优先级信息通过信令的方式发送，通过信令中的特定比特位表示第一同步源优先级信息。例如，第一同步源优先级信息包括终端的能力信息和业务等级信息，可通过8bit中的前4bit表示终端的能力信息，后4bit表示业务等级信息。当然，本申请中不限于上述示例，其他同步源优先级信息的携带方式也在本申请的保护范围之内。
作为一种实施方式，所述终端发送所述第一同步源优先级信息，包括：所述终端通过广播、单播或组播的方式发送所述第一同步源优先级信息。
这里，终端发送第一同步源优先级信息至节点设备，节点设备包括其他终端、基站或中继设备中的至少一种节点设备。作为第一种实施方式，终端可通过单播方式发送第一同步源优先级信息至节点设备，或者通过单播方式逐一发送第一同步源优先级信息至至少两个节点设备。作为第二种实施方式，终端可通过组播方式发送第一同步源优先级信息至至少两个节点设备。作为第三种实施方式，终端可通过广播的方式发送第一同步源优先级信息，使节点设备接收到该第一同步源优先级信息。
作为一种实施方式，所述方法还包括：所述终端基于所述第一同步源优先级信息采用第一周期更新自身的第一同步源优先级列表。
这里，终端预先配置同步源优先级列表(记为第一同步源优先级列表)，作为一种实施方式，该第一同步源优先级列表中预先配置有同步源优先级，例如配置的同步源优先级可包括GNSS、eNB和UE之间的优先级相对关系； 作为另一种实施方式，该第一同步源优先级列表中还可包括其他节点设备发送的同步源优先级信息。而本实施例中，获得第一同步源优先级信息后，按照第一周期更新第一同步源优先级列表。可以理解，在获得第一同步源优先级信息后，检测距离上一次更新第一同步源优先级列表的时间是否已到达第一周期；在到达第一周期后，基于获得的第一同步源优先级信息更新第一同步源优先级列表。
作为一种实施方式，所述终端发送所述第一同步源优先级信息，包括：所述终端基于第二周期发送所述第一同步源优先级信息。
本实施例中，所述第一周期和所述第二周期基于业务测量周期确定；所述第一周期和所述第二周期相同或不同。
作为一种示例，若业务测量周期满足{20,50,100,200,…,1000}毫秒(ms)，则作为一种实施方式，第一周期和第二周期相同，第一周期和第二周期可配置为当前的业务测量周期，或者配置为业务测量周期所满足的可选范围内的任一业务测量周期，例如上述业务测量周期集合中的任一业务测量周期。作为另一实施方式，第一周期和第二周期不同；可选的，第一周期小于第二周期，或者第一周期大于第二周期。
采用本发明实施例的技术方案，一方面，通过终端基于自身的能力信息和/或业务等级信息确定同步源优先级信息并发送给节点设备(如发送给其他终端、基站或中继设备)，实现了基于终端自身的能力信息和/或业务等级信息的QoS保障，使终端能够及时有效的选择到最高优先级的同步源进行同步，保证了业务的连续性，减少了不必要的切换等问题带来的时延或业务中断；另一方面，终端周期性的动态维护同步源优先级列表，以及周期性的发送同步源优先级信息，以提高终端与最优同步源同步通信的及时和稳定性。
本申请实施例还提供了一种同步源优先级确定方法。图3是本申请实施例提供的同步源优先级确定方法的流程示意性图二，如图3所示，所述方法包括：
步骤201：终端基于所述终端的能力信息和/或业务等级信息确定第一同步源优先级信息；
步骤202：所述终端基于第二周期发送所述第一同步源优先级信息；

本实施例中，步骤201至步骤202体可参照前述实施例中的步骤101至步骤102的详细阐述，这里不再赘述。
本实施例中，所述终端接收第一节点设备的第二同步源优先级信息，包括：所述终端接收第一节点设备通过单播、组播或广播的方式发送的第二同步源优先级信息。这里，第二同步源优先级为第一节点设备获得的同步源优先级信息，作为一种示例，第二同步源优先级信息可以是作为第一 节点设备的终端基于自身的能力信息和/或业务等级信息确定的同步源优先级信息。
这里，第二同步源优先级信息为第一节点设备获得的同步源优先级信息；第一节点设备包括其他终端、基站或中继设备中的至少一种节点设备。作为第一种实施方式，第一节点设备通过单播方式发送第二同步源优先级信息，终端可通过单播方式接收到第二同步源优先级信息。作为第二种实施方式，第一节点设备通过组播方式发送第二同步源优先级信息，终端可通过组播方式接收到第二同步源优先级信息。作为第三种实施方式，第一节点设备可通过广播方式发送第二同步源优先级信息，使得终端接收到该第二同步源优先级信息。
在另一实施例中，所述方法还包括：所述终端基于所述第一同步源优先级信息以及所述第二同步源优先级信息更新自身的第一同步源优先级列表；所述第一同步源优先级列表包括基于同步源优先级信息排序的多个同步源；所述终端基于所述第一同步源优先级列表确定优先级最高的同步源。
本实施例中，所述第一同步源优先级列表中的同步源的排序与所述同步源的优先级相关联；其中，所述同步源的优先级与所述终端的能力信息和/或业务等级信息正相关。可以理解，若第一同步源优先级列表中的同步源排序按照优先级由高到低排序，则终端的能力信息表明终端能力越强，优先级越高，排序越靠前；业务等级信息表明业务等级越高，优先级越高，排序越靠前。
作为一种实施方式，所述终端的能力信息和业务等级信息与第一同步源优先级列表中的同步源的排序的相关性中，业务等级信息的相关性高于终端的能力信息的相关性，以至少保证终端的业务需求。
作为一种示例，如图4所示，假设有三个终端的同步源优先级信息，每个同步源优先级信息中均包括终端的能力信息(可记为V-capacity，简化称为V-c)和业务等级信息(可记为V-QoS)，则三个终端的V-capacity和V-QoS相比较可得到：
若某一终端的V-capacity和V-QoS均高于其他终端，则该终端对应的同步源优先级为高，如4图中的第一象限所示；若某一终端的V-QoS高而V-capacity低，则该终端对应的同步源优先级为次高；若某一终端的V-QoS低而V-capacity高，则终端对应的同步源优先级为次低，若某一终端的V-capacity和V-QoS均低，则该终端对应的同步源优先级为低。
可以理解，若某一终端的V-capacity和/或V-QoS高，则提升该终端对应的同步源的优先级。

本实施例中，终端在处于第二模式时，基于预先配置的同步源优先级确定同步源，例如预先配置同步源为GNSS和同步源为演进型基站(eNB)的优先级高于同步源为UE的优先级，可记为{GNSS,eNB}>UE，其中，选择同步源GNSS或eNB的优先级是可配置的，则预先配置的结果确定优先级最高的同步源。
在一实施例中，所述方法还包括：所述终端发送确定的所述优先级最高的同步源。
本实施例中，终端将确定的优先级最高的同步源通过指示信息发送给节点设备。作为一种实施方式，该指示信息可包括预设数量的比特位，通过不同的比特位表示不同类型的同步源。例如指示信息包括四个比特位，四个比特位的首个比特位可表示同步源为基站，若该首个比特位为“1”，可表示确定的优先级最高的同步源为基站；若首个比特位为“0”，可表示基站不是优先级最高的同步源；除首位意外的其他三个比特位可表示终端。
其中，所述终端可通过单播、组播或广播的方式发送所述优先级最高的同步源。
在一实施例中，所述方法还包括：所述终端将所述第二同步源优先级信息发送至第二节点设备；所述第二节点设备为与所述终端连接的节点设备中除所述第一节点设备以外的其他节点设备。

在一实施例中，所述方法还包括：所述终端将所述第一同步源优先级列表发送至第二节点设备；所述第二节点设备为与所述终端连接的节点设备中除所述第一节点设备以外的其他节点设备。
这里，所述终端通过广播、单播或组播的方式将所述第一同步源优先级列表发送至第二节点设备；所述第二节点设备可以是与终端连接的其他终端，或者基站、中继设备等节点设备。
本实施例中，终端与第一节点设备和第二节点设备可组成多跳(multi-hop)网络，终端将自身的第一同步源优先级列表发送至第二节点设备，以共享同步源优先级列表中的同步源优先级信息。
其中，终端可采用第四周期将所述第一同步源优先级列表发送至第二节点设备；其中，所述第四周期基于业务测量周期确定；第三周期可与第一周期和/或第二周期相同，也可与第一周期和/或第二周期不同。
