Description

小区重选方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种小区重选方法、装置及存储介质。
背景技术
目前，为了最大程度的保证终端一直驻留在合适的小区，当终端在某个小区驻留适当时间之后，比如1s之后，终端将进行小区重选。其中，当终端当前所在的服务小区(serving cell)和邻小区(neighbor cell)对应同一个频率时，终端此时进行的是频率内小区重选过程。
相关技术中，终端是根据R准则来实现频率内小区重选过程，也即，终端根据R准则对服务小区的信号质量和邻小区的信号质量进行排序，从中选择信号质量最好的小区进行驻留。其中，R准则的公式如下：
Figure PCTCN2017115500-appb-000001
Figure PCTCN2017115500-appb-000002
R s为服务小区的信号质量，Q meas,s是服务小区参考信号的信号质量，Q Hyst是为了避免终端在排序接近的两个小区内频繁地进行乒乓重选而设置的小区重选滞后值；R n为邻小区的信号质量，Q meas,n是邻小区参考信号的信号质量，Q offset是协议中定义的频率内的小区重选偏移值；另外，

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。由于相关技术中，不管服务小区是否是高铁专用网络中的小区，服务小区的系统消息中携带的Q Hyst均是固定的，并且不管邻小区是否是高铁专用网络中的小区，邻小区的系统消息中携带的Q offset也是固定不变的。也即，对于普通终端和高铁上的终端而言，这两种不同类型的终端从服务小区重选到邻小区的概率相同，导致终端进行频率内小区重选的灵活性较低。
因此，本公开实施例提供了一种小区重选方法，获取目标小区的系统消息携带的小区重选参数，由于目标小区的小区重传参数时根据是终端速度设置的，因此当终端根据该小区重选参数确定该目标小区的信号质量时，终端是结合了自身的速度来确定该目标小区的信号质量，也即，终端是考虑了自身的速度之后，从服务小区和至少一个邻小区中选择一个小区进行驻留，从而提高了终端进行频率内小区重选的灵活性。

在步骤201中，发送目标小区的系统消息，该系统消息携带小区重选参数，该小区重选参数是根据终端速度设置的。
在本公开实施例中，由于目标小区的小区重传参数时根据是终端速度设置的，因此当终端根据该小区重选参数确定该目标小区的信号质量时，终端是结合了自身的速度来确定该目标小区的信号质量，也即，终端是考虑了自身的速度之后，从服务小区和至少一个邻小区中选择一个小区进行驻留，从而提高了终端进行频率内小区重选的灵活性。

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是本公开实施例提供的另一种小区重选方法。如图3所示，该方法包括如下步骤：
在步骤301中，基站发送目标小区的系统消息，该系统消息携带小区重选参数，该小区重选参数是根据终端速度设置的。
在本公开实施例中，对于每个小区，基站将周期性地广播该小区的系统消息，该小区的系统消息通常携带一些参数，比如该小区的小区重选滞后值以及小区重选偏移值。
进一步地，为了提高终端进行小区驻留时的灵活性，基站可以预先为某些小区设置小区重选参数，该小区重选参数是根据终端速度设置的，以提高速度大的终端在这些小区中驻留的概率。
为了后续便于说明，将基站预先为某些小区设置的小区重选参数进行解释说明。
由R准则公式可知，影响终端选择是否在某个小区上驻留的主要参数包括小区重选滞后值和小区重选偏移值，因此，在本公开实施例中，将分别提供两种不同的小区重选参数设置方式，为了便于说明，将设置了小区重选参数的小区称为目标小区：
第一种设置方式，针对目标小区的小区重选滞后值设置小区重选参数。
其中，在第一种设置方式中，为目标小区设置小区重选参数有以下三种实现方式：
实现方式(1)，该目标小区为第一网络中的小区，该小区重选参数包括初始小区重选滞后值和滞后值比例因子，该滞后值比例因子用于增加速度大于预设速度的终端驻留在该第一网络的小区的概率。
也即，对于第一网络中的小区，该小区的系统消息携带小区重选参数，该小区重选参数包括初始小区重选滞后值和滞后值比例因子。但是对于其他网络中的小区，该小区的系统消息仅仅携带小区重选滞后值。
其中，为了实现该滞后值比例因子用于增加速度大于预设速度的终端驻留在该第一网络的小区的概率，该滞后值比例因子大于0。
比如，第一网络为高铁专用网络，也即，对于高铁专用网络中的小区，该小区的系统消息携带小区重选参数，该小区重选参数包括初始小区重选滞后值和滞后值比例因子。而对于公共LTE(Long Term Evolution，长期演进)中的小区，该小区的系统消息中只携带小区重选滞后值。
实现方式(2)，该小区重选参数包括初始小区重选滞后值和至少两个滞后值比例因子，该至少两个滞后值比例因子与至少两个速度区间对应，且当该目标小区为第一网络中的小区时，取值大于预设速度的速度区间对应的滞后值比例因子大于0，取值小于该预设速度的速度区间对应的滞后值比例因子小于0，当该目标小区为第二网络中的小区时，取值大于该预设速度的速度区间对应的滞后值比例因子小于0，取值小于该预设速度的速度区间对应的滞后值比例因子大于0。
也即，在实现方式(2)中，针对不同网络中的小区设置不同的小区重选参数。
比如，第一网络为高铁专用网络，第二网络为公共LTE网络，该至少两个速度区间分别为第一速度区间和第二速度区间，与第一速度区间对应的滞后值比例因子为第一滞后值比例因子，与第二速度区间对应的滞后值比例因子为第二滞后值比例因子。
其中，第一速度区间的取值大于第二速度区间的取值，比如，该第一速度区间可以为大于200km/h，第二速度区间可以为小于200km/h。
此时，对于高铁专用网络中的小区，可以将第一滞后值比例因子设置为2，将第二滞后值比例因子设置为-2。
对于公共LTE网络中的小区，可以将第一滞后值比例因子设置为-2，将第二滞后值比例因子设置为2。
实现方式(3)，该小区重选参数包括至少两个小区重选滞后值，该至少两个小区重选滞后值与至少两个速度区间对应，且当该目标小区为第一网络中的小区时，每个小区重选滞后值的大小与对应的速度区间的取值呈正相关，当该目标小区为第二网络中的小区时，每个小区重选滞后值的大小与对应的速度区间的取值呈负相关。
也即，在实现方式(3)中，针对第一网络终端的小区，该小区的系统消息携带的至少两个小区重选滞后值中，当小区重选滞后值对应的速度区间的取值越大，该小区重选滞后值也越大。
针对第二网络终端的小区，该小区的系统消息携带的至少两个小区重选滞后值中，当小区重选滞后值对应的速度区间的取值越大，该小区重选滞后值越小。
比如，第一网络为高铁专用网络，第二网络为公共LTE网络，该至少两个 小区重选滞后值分别为第一小区重选滞后值，第二小区重选滞后值和第三小区重选滞后值，对应的速度区间分别为第一速度区间、第二速度区间和第三速度区间。
其中，第一速度区间、第二速度区间和第三速度区间的取值依次减小。比如，该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。
此时，对于高铁专用网络的小区，设置的三个小区重选滞后值的大小顺序为：第一小区重选滞后值大于第二小区重选滞后值，第二小区重选滞后值大于第三小区重选滞后值。
对于公共LTE网络中的小区，设置的三个小区重选滞后值的大小顺序为：第一小区重选滞后值小于第二小区重选滞后值，第二小区重选滞后值小于第三小区重选滞后值。
第二种设置方式，针对目标小区的小区重选偏移值设置小区重选参数。
在一种可能的实现方式中，该小区重选参数包括至少两个小区重选偏移值，该至少两个小区重选偏移值与至少两个速度区间对应，且当该目标小区为第一网络中的小区时，每个小区重选偏移值的大小与对应的速度区间的取值呈负相关，当该目标小区为第二网络中的小区时，每个小区重选偏移值的大小与对应的速度区间的取值呈正相关。
也即，针对第一网络终端的小区，该小区的系统消息携带的至少两个小区重选偏移值中，当小区重选偏移值对应的速度区间的取值越大，该小区重选偏移值越小。
针对第二网络终端的小区，该小区的系统消息携带的至少两个小区重选偏移值中，当小区重选偏移值对应的速度区间的取值越大，该小区重选偏移值越大。
比如，第一网络为高铁专用网络，第二网络为公共LTE网络，该至少两个小区重选偏移值分别为第一小区重选偏移值，第二小区重选偏移值和第三小区重选偏移值，对应的速度区间分别为第一速度区间、第二速度区间和第三速度区间。
其中，第一速度区间、第二速度区间和第三速度区间的取值依次减小。比如，该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。
此时，对于高铁专用网络的小区，设置的三个小区重选偏移值的大小顺序为：第一小区重选偏移值小于第二小区重选偏移值，第二小区重选偏移值小于第三小区重选偏移值。
对于公共LTE网络中的小区，设置的三个小区重选偏移值的大小顺序为：第一小区重选偏移值大于第二小区重选偏移值，第二小区重选偏移值大于第三小区重选偏移值。
在步骤302中，终端获取目标小区的系统消息中携带的小区重选参数，该小区重选参数是根据终端速度设置的，该目标小区为服务小区或至少一个邻小区。
由步骤301可知，在本公开实施例中，可以针对小区重选滞后值设置小区重选参数，也可以针对小区重选偏移值设置小区重选参数，因此，对于终端而言，当目标小区的系统消息中携带的小区重选参数时，该目标小区可能是服务小区也可能是该至少一个邻小区。
也即，当基站预先针对小区重选滞后值设置小区重选参数时，此时该目标小区将是终端当前所在的服务小区。当基站预先针对小区重选偏移值设置小区重选参数时，此时该目标小区将是该终端当前所在的服务小区的邻小区。
其中，当该目标小区为服务小区时，终端可以直接从该服务小区的系统消息中确定该目标小区的小区重选参数。
当该目标小区为至少一个邻小区时，终端需从每个邻小区的系统消息中确定每个邻小区的小区重选参数。
需要说明的是，服务小区为终端当前接入的小区，邻小区是与服务小区在网络中相邻的小区。对于任意一个小区，该小区的邻小区是运营商预先通过网络覆盖情况规划的。
另外，由于本公开实施例针对的是频率内小区重选过程，因此，该服务小区对应的频率和该至少一个邻小区对应的频率相同，也即，服务小区和该至少一个邻小区属于同一个频率对应的小区。
在步骤303中，终端根据该小区重选参数，确定该目标小区的信号质量。
由步骤302可知，目标小区可以是终端当前所在的服务小区，也可以是该服务小区的邻小区。因此，步骤303相应地存在以下两种应用场景。
场景一：该目标小区为服务小区，也即基站预先针对小区重选滞后值设置小区重选参数。
由步骤301可知，在场景一中，基站设置小区重选参数有三种不同的实现方式，下面将根据这三种不同的实现方式展开说明步骤303：
针对步骤301中的实现方式(1)，步骤303的实现方式为：终端确定自身的移动速度，当该移动速度大于预设速度时，将初始小区重选滞后值和滞后值比例因子相加，得到目标小区重选滞后值，并根据目标小区重选滞后值，确定目标小区的信号质量。
当该移动速度小于或等于预设速度时，将初始小区重选滞后值确定为目标小区重选滞后值，并根据目标小区重选滞后值，确定目标小区的信号质量。
比如，该服务小区是高铁专用网络中的小区，当该移动速度大于预设速度时，表明终端当前处于高铁上，此时为了增大该终端在该服务小区上驻留的概率，终端将该小区重选参数包括的初始小区重选滞后值与该滞后值比例因子相加，并相加后的数值确定为目标小区重选滞后值。
相应地，当该移动速度小于或等于预设速度时，表明终端当前没有处于高铁上，此时没有必要增大该终端在该服务小区上驻留的概率，终端则将该小区重选参数包括的小区重选滞后值直接确定为目标小区重选滞后值。
其中，终端根据目标小区重选滞后值，确定目标小区的信号质量，也即，终端直接将目标小区重选滞后值作为R准则公式中的小区重选滞后值，根据R准则公式确定目标小区的信号质量。因此，当终端当前在高铁上时，通过滞后值比例因子增加该R准则中的小区重选滞后值，以提高高铁上的终端在该高铁专用网络的小区中驻留的概率。
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。
需要说明是，若服务小区的系统消息中没有携带该小区重选参数，则表明该服务小区当前不是第一网络中的小区，此时可以直接将系统消息中携带的小区重选滞后值确定R准则中的小区重选滞后值。
比如，第一网络为高铁专用网络，当该服务小区是公共LTE网络中的小区 时，此时无论终端是高铁上的终端还是非高铁上的终端，终端都可以直接将服务小区的系统消息的小区重选滞后值确定该R准则中的小区重选滞后值。
当终端确定出目标小区重选滞后值时，也即确定出R准则中的小区重选滞后值滞，此时终端可以根据下述公式确定该服务小区的信号质量：
Figure PCTCN2017115500-appb-000005
其中，R s为服务小区的信号质量，Q meas,s是服务小区参考信号的信号质量，Q Hyst是为了避免终端在排序接近的两个小区内频繁地进行乒乓重选而设置的小区重选滞后值；另外，
Figure PCTCN2017115500-appb-000006
和
Figure PCTCN2017115500-appb-000007
是协议中定义的临时信号质量和SCPTM(Single-cell Point-to-Multipoint，在单一小区支持群播服务)技术中的参考信号质量。
针对步骤301中的实现方式(2)，步骤303的实现方式为：确定自身的移动速度；从该至少两个速度区间中选择与该移动速度对应的速度区间，得到目标速度区间；从该至少两个滞后值比例因子中选择与该目标速度区间对应的滞后值比例因子；将该初始小区重选滞后值和选择的滞后值比例因子相加，得到目标小区重选滞后值；根据该目标小区重选滞后值，确定该目标小区的信号质量。
由步骤301可知，当该目标小区为第一网络中的小区时，取值大于预设速度的速度区间对应的滞后值比例因子大于0，取值小于该预设速度的速度区间对应的滞后值比例因子小于0，当该目标小区为第二网络中的小区时，取值大于该预设速度的速度区间对应的滞后值比例因子小于0，取值小于该预设速度的速度区间对应的滞后值比例因子大于0。
因此，当终端当前的移动速度大于预设速度，且服务小区为第一网路中的小区时，终端确定的目标滞后值比例因子大于0，此时终端相当于将初始小区重选滞后值进行了放大，并将放大后的数值确定为目标小区重选滞后值，以增大该终端在第一网络中的小区驻留的概率。
当终端当前的移动速度小于预设速度，且服务小区为第一网路中的小区时，终端确定的目标滞后值比例因子小于0，此时终端相当于将初始小区重选滞后值进行了缩小，并将缩小后的数值确定为目标小区重选滞后值，以减小该终端在第一网络中小区驻留的概率。
比如，当第一网络为高铁专用网络，第二网络为公共LTE网络，通过上述方式可以增大高铁上的UE在高铁专用网络中的小区驻留的概率，或增大非高 铁上的UE在公共LTE网络中的小区驻留的概率。
针对步骤301中的实现方式(3)，步骤303的实现方式为：确定自身的移动速度；从该至少两个速度区间中选择与该移动速度对应的速度区间，得到目标速度区间；从该至少两个小区重选滞后值中选择与该目标速度区间对应的小区重选滞后值，得到目标小区重选滞后值；根据该目标小区重选滞后值，确定该目标小区的信号质量。
由于此时，当该目标小区为第一网络中的小区时，每个小区重选滞后值的大小与对应的速度区间的取值呈正相关，当该目标小区为第二网络中的小区时，每个小区重选滞后值的大小与对应的速度区间的取值呈负相关。
也即，若服务小区为第一网络中的小区，当终端当前的速度越大时，通过上述方式确定的目标小区重选滞后值越大，以增大速度大的终端在第一网络中的小区驻留的概率。也即，当第一网络为高铁专用网络时，可以增大高铁上的UE在该高铁专用网络中的小区驻留的概率。
若服务小区为第二网络中的小区，当终端当前的速度越大时，通过上述方式确定的目标小区重选滞后值越小，以增大速度低的终端在第二网络中的小区驻留的概率。也即，当第二网络为公共LTE网络时，可以增大非高铁上的UE在该公共LTE网络中的小区驻留的概率。
场景二：该目标小区为至少一个邻小区，也即基站预先针对小区重选偏移值设置小区重选参数，也即，每个邻小区携带小区重选参数。
此时，对于任意一个邻小区，该邻小区的系统消息中携带小区重选参数，且该小区重选参数包括至少两个小区重选偏移值，该至少两个小区重选偏移值与至少两个速度区间对应。因此，步骤303的是实现方式可以为：确定自身的移动速度；从该至少两个速度区间中选择与该移动速度对应的速度区间，得到目标速度区间；根据该目标速度区间，从每个邻小区的小区重选参数包括的至少两个小区重选偏移值中确定与每个邻小区对应的目标小区重选偏移值；根据与每个邻小区对应的目标小区重选偏移值，确定每个邻小区的信号质量。
此时，由于当该邻小区为第一网络中的小区时，每个小区重选偏移值的大小与对应的速度区间的取值呈负相关，当该目标小区为第二网络中的小区时，每个小区重选偏移值的大小与对应的速度区间的取值呈正相关。
也即，对于任意一个邻小区，若该邻小区为第一网络中的小区，当终端当前的速度较大，比如终端当前处于高铁上，此时，终端确定的目标小区重选偏 移值越小，由R准则公式可知，当小区重选偏移值越小时，该小区的信号质量越大，也即，当终端当前的速度较大时，终端驻留在第一网络中的小区的概率越大。
若该邻小区为第二网络中的小区，当终端当前的速度较小，比如终端当前没有处于高铁上，此时，终端确定的目标小区重选偏移值越小，由R准则公式可知，当小区重选偏移值越小时，该小区的信号质量越大，也即，当终端当前的速度较小时，终端驻留在第二网络中的小区的概率越大。
因此，当第一网络为高铁专用网络，第二网络为公共LTE网络时，通过上述方式可以增大高铁上的UE驻留在高铁专用网络中的概率，并增大非高铁上的UE驻留在公共LTE网路中的概率。
在步骤304中，终端确定该服务小区和至少一个邻小区中除该目标小区之外的其他小区的信号质量。
当终端通过步骤303确定出目标小区的信号质量之后，为了选择合适的小区进行驻留，还需确定服务小区和至少一个邻小区中除目标小区之外的其他小区的信号质量。
其中，当目标小区为服务小区时，此时邻小区的系统消息和相关技术中的系统消息相同，也即，此时邻小区的系统消息中携带小区重选偏移值，此时终端可以直接根据下述公式确定每个邻小区的信号质量：
Figure PCTCN2017115500-appb-000008
其中，R n为邻小区的信号质量，Q meas,n是邻小区参考信号的信号质量，Q offset是协议中定义的频率内的小区重选偏移值；另外，
Figure PCTCN2017115500-appb-000009
和
Figure PCTCN2017115500-appb-000010
是协议中定义的临时信号质量和SCPTM(Single-cell Point-to-Multipoint，在单一小区支持群播服务)技术中的参考信号质量。
也即，当目标小区为服务小区时，终端是直接根据每个邻小区的系统消息携带的小区重选偏移值直接确定每个邻小区的信号质量。
当目标小区为至少一个邻小区时，此时服务小区的系统消息和相关技术中的系统消息相同，也即，此时服务小区的系统消息中携带小区重选滞后值，此时终端可以直接根据R准则公式确定服务小区的信号质量。也即，当目标小区为至少一个邻小区时，终端是直接根据服务小区的系统消息携带的小区重选滞后值直接确定每个邻小区的信号质量。
在步骤305中，终端根据该目标小区的信号质量和该其他小区的信号质量， 从该服务小区和该至少一个邻小区选择一个小区进行驻留。
当终端确定根据上述步骤302和步骤303确定出该服务小区的信号质量和每个邻小区的信号质量之后，终端可以直接根据步骤305选择一个信号质量最好的小区的进行驻留。
比如，该至少一个邻小区分别为邻小区1、邻小区2和邻小区3，终端通过步骤302和步骤303确定服务小区和该3个邻小区的信号质量，并对服务小区和该3个邻小区的信号质量进行排序，排序结果为：邻小区2的信号质量>服务小区的信号质量>邻小区1的信号质量>邻小区3的信号质量，此时，终端可直接选择邻小区2进行驻留，以实现从服务小区重选到邻小区2。
在本公开实施例中，当目标小区为服务小区时，当服务小区为第一网络中的小区时，终端是根据小区重选参数中包括的小区重选滞后值和滞后值比例因子确定该服务小区的信号质量，而不是仅仅通过小区重选滞后值直接确定服务小区的信号质量，以增大高铁上的终端在该第一网络的小区中驻留的概率。另外，当目标小区为至少一个邻小区时，每个邻小区的小区重选参数包括至少两个小区重选偏移值，由于该至少两个小区重选偏移值与至少两个速度区间对应，终端可以根据自身情况选择合适的小区重选偏移值，以增大高铁上的终端驻留到高铁专用网络中的小区的概率。
