具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
在对本公开实施例进行详细的解释说明之前，先对本公开实施例的应用场景予以介绍。目前高铁专用网络的基站发送的系统消息和公共LTE网络的基站发送的系统消息中携带的频率优先级排序相同，也即，无论是高铁专用网络的基站发送的系统消息还是公共LTE网络的基站发送的系统消息，两者携带的频率优先级排序为同一个频率优先级排序。并且，在该同一个频率优先级排序中，高铁专用网络采用的频率的优先级通常大于普通LTE网络采用的频率的优先级。因此，无论是高铁上的终端还是非高铁上的终端，若该终端扫描的频率中包括高铁专用网络采用的频率时，将导致该终端优先驻留在高铁专用网络采用的频率对应的某个小区，降低了终端进行小区重选的灵活性。
所以，本公开实施例提供了一种小区重选方法，以使终端在接收到系统消息时，可以根据自身的速度选择合适的频率优先级排序，并根据选择的频率优先级排序进行小区重选，从而提高了终端进行小区重选的灵活性。
图1是本公开实施例提供的一种小区重选方法流程图，应用于终端，如图1所示，该方法包括以下步骤：
在步骤101中，确定接收到的系统消息携带的至少两个频率优先级排序，该至少两个频率优先级排序是针对不同的终端速度设置的。
在步骤102中，从该至少两个频率优先级排序中选择目标频率优先级排序。
在步骤103中，根据该目标频率优先级排序从扫描到的多个频率中选择目标频率，并在该目标频率对应的多个小区中选择一个小区进行驻留。
在本公开实施例中，由于系统消息携带至少两个频率优先级排序中，且该至少两个频率优先级排序是针对不同的终端速度设置的，因此，通过本公开实施例提供的小区重选方法，终端在接收到系统消息时，可以根据自身的速度选择合适的频率优先级排序，并根据选择的频率优先级排序进行小区重选，提高了终端进行小区重选的灵活性。
可选地，每个频率优先级排序包括第一网络采用的频率的优先级和第二网络采用的频率的优先级，该至少两个频率优先级排序与至少两个速度区间对应，且在取值大于预设速度的速度区间对应的频率优先级排序中，第一网络采用的频率的优先级大于第二网络采用的频率的优先级，在取值小于该预设速度的速度区间对应的频率优先级排序中，第一网络采用的频率的优先级小于第二网络采用的频率的优先级。
可选地，从该至少两个频率优先级排序中选择目标频率优先级排序，包括：
获取自身的移动速度；
从该至少两个速度区间中选择与自身的移动速度对应的速度区间，得到目标速度区间；
从该至少两个频率优先级排序中选择与该目标速度区间对应的频率优先级排序，得到目标频率优先级排序。
可选地，该第一网络采用的频率与该第二网络采用的频率之间不存在交集。
上述所有可选技术方案，均可按照任意结合形成本公开的可选实施例，本公开实施例对此不再一一赘述。
图2是本公开实施例提供的另一种小区重选方法流程图，应用于基站，如 图2所示，该方法包括以下步骤：
在步骤201中，发送系统消息，该系统消息携带至少两个频率优先级排序，该至少两个频率优先级排序是针对不同的终端速度设置的。
在本公开实施例中，由于基站发送的系统消息携带至少两个频率优先级排序中，且该至少两个频率优先级排序是针对不同的终端速度设置的，因此，通过本公开实施例提供的小区重选方法，终端在接收到系统消息时，可以根据自身的速度选择合适的频率优先级排序，并根据选择的频率优先级排序进行小区重选，提高了终端进行小区重选的灵活性。
可选地，每个频率优先级排序包括第一网络采用的频率的优先级和第二网络采用的频率的优先级，该至少两个频率优先级排序与至少两个速度区间对应，且在取值大于预设速度的速度区间对应的频率优先级排序中，该第一网络采用的频率的优先级大于该第二网络采用的频率的优先级，在取值小于该预设速度的速度区间对应的频率优先级排序中，该第一网络采用的频率的优先级小于该第二网络采用的频率的优先级。
可选地，该第一网络采用的频率与该第二网络采用的频率之间不存在交集。
上述所有可选技术方案，均可按照任意结合形成本公开的可选实施例，本公开实施例对此不再一一赘述。
图3本公开实施例提供的另一种小区重选方法流程图，如图3所示，该小区重选方法包括以下步骤。
在步骤301中，基站向终端发送系统消息，该系统消息携带至少两个频率优先级排序，该至少两个频率优先级排序是针对不同的终端速度设置的。
需要说明的是，在本公开实施例中，为了提高终端进行小区重选的灵活性，对于任一个基站发送的系统消息，该系统消息携带至少两个频率优先级排序，该至少两个频率优先级排序是针对不同的终端速度设置的，以便于终端根据自身的速度选择合适的频率优先级排序。
为了后续便于说明，在此先对预先设置的至少两个频率优先级排序进行介绍。
其中，每个频率优先级排序包括第一网络采用的频率的优先级和第二网络采用的频率的优先级，该至少两个频率优先级排序与至少两个速度区间对应， 且在取值大于预设速度的速度区间对应的频率优先级排序中，第一网络采用的频率的优先级大于第二网络采用的频率的优先级，在取值小于该预设速度的速度区间对应的频率优先级排序中，该第一网络采用的频率的优先级小于该第二网络采用的频率的优先级。
在一种可能的实现方式中，预先针对两个速度区间设置两个频率优先级排序，该两个速度区间为第一速度区间和第二速度区间，与第一速度区间对应的频率优先级排序为第一频率优先级排序，与第二速度区间对应的频率优先级排序为第二频率优先级排序。其中，第一速度区间为取值大于预设速度的速度区间，第二速度区间为取值小于预设速度的速度区间。
此时，在第一频率优先级排序中，第一网络采用的频率的优先级大于第二网络采用的频率的优先级。在第二频率优先级排序中，第一网络采用的频率的优先级大于第二网络采用的频率的优先级。
比如，第一网络为高铁专用网络，第二网路为公共LTE(Long Term Evolution，长期演进)网络。针对四个频率：F1、F2、F3和F4，其中，F1和F2是高铁专用网络采用的频率，F3和F4是公共LTE网络采用的频率。预先设置两个不同的速度区间，第一速度区间和第二速度区间。其中，第一速度区间为大于200km/h，第二速度区间为小于200km/h。
针对第一速度区间设置的第一频率优先级排序如下述表1所示，其中，频率F1的优先级设置为8，频率F2的优先级设置为6，频率F3的优先级设置为4，频率F4的优先级设置为2。也即，在取值较大的速度区间对应的频率优先级排序中，高铁专用网络采用的频率的优先级大于公共LTE网络采用的频率的优先级。
表1
频率 F1 F2 F3 F4
优先级 8 6 4 2
针对第二速度区间设置的第二频率优先级排序如下述表2所示，其中，频率F1的优先级设置为2，频率F2的优先级设置为4，频率F3的优先级设置为6，频率F4的优先级设置为8。也即，取值较小的速度区间对应的频率优先级排序中，高铁专用网络采用的频率的优先级小于公共LTE网络采用的频率的优先级。
表2
频率 F1 F2 F3 F4
优先级 2 4 6 8
由表1和表2可知，在本公开实施例中，针对任一个频率，相当于根据第一速度区间和第二速度区间设置了两种不同的优先级，比如，对于频率F1，设置了两个优先级，分别为与高速区间对应的8和与低速区间对应的2。
需要说明的是，任意一个频率优先级排序均是对协议中定义的所有小区的频率进行了排序。上述表1和表2只是以频率F1、F2、F3和F4为例进行说明，并不能构成对公开实施例的限定。
在另一种可能的实现方式中，预先针对三个速度区间设置三个频率优先级排序，该三个速度区间为第一速度区间、第二速度区间和第三速度区间，与第一速度区间对应的频率优先级排序为第一频率优先级排序，与第二速度区间对应的频率优先级排序为第二频率优先级排序，与第三速度区间对应的频率优先级排序为第三频率优先级排序。其中，第一速度区间、第二速度区间和第三速度区间对应的取值依次减小。
其中，针对每个速度区间设置对应的频率优先级排序可以参考上述一种可能的实现方式，在此不再详细阐述。
比如，第一速度区间为大于200km/h，第二速度区间为200-80km/h，第三速度区间为小于80km/h，也即，在本公开实施例中，针对三个不同的速度区间设置了三个不同的频率优先级排序。
另外，需要说明的是，在本公开实施例中，第一网络采用的频率与第二网络采用的频率之间不存在交集。
比如，当第一网络为高铁专用网络，第二网络为公共LTE网络时，表明高铁专用网络采用的频率与公共LTE网络采用的频率之间不存在交集。也即，协议中预先规定哪些频率是高铁专用网络采用的频率，哪些是公共LTE网络采用的频率。并且，在预先规定出高铁专用网络采用的频率之后，该频率对应的多个小区均为该高铁专用网络中的小区。同样地，在预先规定出公共LTE网络采用的频率之后，该频率对应的多个小区均为该公共LTE网络中的小区。
在步骤302中，终端确定接收到的系统消息携带的至少两个频率优先级排序。
在本公开实施例中，当终端需要进行小区重选时，终端需先确定接收到的系统消息中携带的至少两个频率优先级排序，以便于根据自身的情况选择合适 的频率优先级排序进行小区重选。
其中，终端根据自身的情况选择合适的频率优先级排序进行小区重选可以通过下述步骤303实现。
在步骤303中，终端从该至少两个频率优先级排中选择目标频率优先级排序。
由步骤301可知，该至少两个频率优先级排序是根据不同的终端速度设置的，且该至少两个频率优先级排序与至少两个速度区间对应。因此，步骤302的实现方式可以为：获取自身的移动速度，从该至少两个速度区间中选择与自身的移动速度对应的速度区间，得到目标速度区间，从该至少两个频率优先级排序中选择与该目标速度区间对应的频率优先级排序，得到目标频率优先级排序。
由于终端是从该至少两个速度区间中选择与自身的移动速度对应的速度区间，然后从该至少两个频率优先级排序中选择与该目标速度区间对应的频率优先级排序。因此，当终端当前的移动速度较大时，目标频率优先级排序为取值较大的速度区间对应的频率优先级排序。
又由于，在取值大于预设速度的速度区间对应的频率优先级排序中，第一网络采用的频率的优先级大于第二网络采用的频率的优先级，因此，当终端当前的移动速度较大时，终端将优先驻留在第一网络采用的频率中。
比如，该至少两个频率优先级排序为表1中的频率优先级排序和表2中的频率优先级排序，且表1中的频率优先级排序对应的速度区间为大于200km/h，表2中的频率优先级排序对应的速度区间为小于200km/h。此时，若终端确定自身的移动速度大于200km/h时，表明终端当前可能处于高铁中，终端可以将表1中的频率优先级排序确定为目标频率优先级排序，以便于后续根据表1中的频率优先级排序进行小区重选。
若终端确定自身的移动速度小于200km/h时，表明终端当前可能不在高铁上，终端可以将表2中的频率优先级排序确定为目标频率优先级排序，以便于后续根据表2中的频率优先级排序进行小区重选。
其中，终端确定当前的移动速度的实现方式可以为：终端可以每隔预设时长通过GPS定位技术(Global Positioning System，全球定位系统)确定当前所处的位置，根据确定出的位置计算该终端在该预设时长内移动的距离，将该距离与该预设时长之间的商作为该终端的移动速度。
另外，预设时长为预先设置的时长，该预设时长可以为5s、10s或30s等。预设速度也为预先设置的速度，该预设速度可以为150千米/小时、200千米/小时或300千米/小时等。
在步骤304中，终端根据该目标频率优先级排序从扫描到的多个频率中选择目标频率，并在该目标频率对应的多个小区中选择一个小区进行驻留。
终端在根据步骤303确定出目标优先级排序之后，由于目标优先级排序包括协议中定义的所有小区的频率的优先级，因此，在目标优先级排序中包括扫描到的多个频率的优先级，也即，终端可以直接根据该目标优先级排序从扫描到的多个频率中选择优先级最大的频率作为目标频率。
终端在确定出目标频率之后，由于每个频率对应多个小区，因此终端在该目标频率对应的多个小区中选择合适的小区进行驻留。在一种可能的实现方式中，终端可以在目标频率对应的多个小区中选择信号质量最好的小区进行驻留。
比如，终端根据步骤303确定表1为目标优先级排序，也即表明终端当前的移动速度较大，也即终端当前可能处于高铁上。若终端扫描到的频率包括F2、F3和F4，由于在表1中，频率F2的优先级为6、频率F3的优先级为4、频率F4的优先级为2，因此，终端可以直接将优先级最大的频率F2确定为目标频率，并在频率F2对应的多个小区中选择合适的小区进行驻留。由于F2是高铁专用网络采用的频率，因此通过本公开实施例提供的小区重选方法，当终端处于高铁上时，终端将优先驻留在高铁专用网络采用的频率对应的小区。
又比如，当终端根据步骤303确定表2为目标优先级排序，表明终端当前的移动速度较小，也即终端当前没有处于高铁上。若终端扫描到的频率包括F2、F3和F4，由于在表2中，频率F2的优先级为4、频率F3的优先级为6、频率F4的优先级为8，因此，终端可以直接将优先级最大的频率F4确定为目标频率，并在频率F4对应的多个小区中选择合适的小区进行驻留。由于F4是公共LTE网络采用的频率，因此通过本公开实施例提供的小区重选方法，当终端没有处于高铁上时，终端将优先驻留在公共LTE网络的小区，从而可以有效避免高铁专用网络的拥塞。
在本公开实施例中，由于基站发送的系统消息携带至少两个频率优先级排序中，且该至少两个频率优先级排序是针对不同的终端速度设置的，因此，通过本公开实施例提供的小区重选方法，终端在接收到系统消息时，可以根据自 身的速度，灵活选择合适的频率优先级排序，并根据选择的频率优先级排序进行小区重选，提高了终端进行小区重选的灵活性。且当第一网络为高铁专用网路，第二网络为公共LTE网络时，通过本公开实施例提供的小区重选方法，终端可以灵活选择合适的频率优先级排序，以使高铁上终端优先驻留在高铁专用网络采用的频率对应的小区，使非高铁上的终端优先驻留在公共LTE网络采用的频率对应的小区，以降低非高铁上的终端接入高铁专用网络的可能性，从而可以有效避免高铁专用网络的拥塞。
