背景技术
小区，也称蜂窝小区，是指在蜂窝移动通信***中，其中的一个基站或基站的一部分(扇形天线)所覆盖的区域，在这个区域内终端设备可以通过小区的信道与基站进行通信。
当终端设备与服务小区通信的信号质量较差时，终端会自发对其他小区进行通信质量检测，并选择信号强度最佳的小区作为服务小区，这个过程称为小区重选。若终端处于快速移动的状态，当前信号强度最佳的小区的信号稳定性可能较差，随着终端的快速移动，小区的信号强度也快速下降，进而导致终端在短时间内频繁进行小区重选，提高终端的功耗，进而导致终端难以在快速移动的状态下，确定合适的小区作为服务小区，使得终端重选至合适小区存在一定滞后性。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
请参考图1，图1为本申请一实施例提供的小区重选的方法流程图，该小区重选方法应用于终端。终端可以是，但不限于个人计算机(Personal Computer，PC)、笔记本电脑、手机、客户前置设备(Customer Premise Equipment，CPE)等。
该小区重选方法，可以包括如下步骤。
S11，获取多个候选服务小区在当前时刻的RSRP值和距离当前时刻预设时长的在先时刻的RSRP值。
其中，RSRP(Reference Singnal Received Power，参考信号接收功率)是终端接收到的候选服务小区的公共参考信号(CRS)功率值，数值为终端的测量带宽内单个RE(Resource Element，资源元素)功率的线性平均值，用于反应该小区有用信号的强度。
在本申请实施例中，候选服务小区为预先确定的符合R准则和S准则的小区，当前时刻到在先时刻的预设时长可以根据具体应用场景进行设定。
具体地，候选服务小区确定的方式可以包括如下步骤。
S101，获取终端当前的服务小区与服务小区的相邻小区的RSRP值。
S102，根据服务小区与相邻小区的优先级以及服务小区和相邻小区的RSRP值，判断是否进行小区重选。
具体地，若服务小区和相邻小区是否处于同等优先级，则当服务小区的RSRP值大 于或等于同等优先级重选对端门限，且持续时长大于或等于门限时长时，进行小区重选。
若服务小区的优先级大于相邻小区，则当相邻小区的RSRP值大于或等于高优先级重选对端门限，且持续时长是否大于或等于门限时长时，进行小区重选。
若服务小区的优先级小于相邻小区，则当相邻小区的RSRP值大于低优先级重选对端门限，服务小区的RSRP值大于低优先级重选对端门限，且持续时长是否大于或等于门限时长时，进行小区重选。
其中，高优先级重选对端门限为服务小区的优先级高于相邻小区时进行小区重选的RSRP阈值、同等优先级重选对端门限为服务小区与相邻小区处于相同优先级时进行小区重选的RSRP阈值、低优先级重选对端门限为服务小区的优先级低于相邻小区时进行小区重选的RSRP阈值及门限时长为小区重选时需要满足的RSRP值持续时长阈值。高优先级重选对端门限、同等优先级重选对端门限、低优先级重选对端门限及门限时长可以由终端的SIB(System Information Block，***信息块)获取，服务小区与相邻小区的各优先级情况下的门限时长相同。
S103，若是，则利用S准则和R准则对相邻小区进行筛选，确定候选服务小区。
终端对小区进行重选，需要通过S准则和R准则对各相邻小区进行筛选，获得候选服务小区，保证经过筛选得到的候选服务小区的信号强度较好。
具体地，S准则为Srxlev＝Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)-Pcompensation，当相邻小区的Srxlev>0时，则该小区符合S准则。
其中，Srxlev为小区接收电平值，Qrxlevmeas为小区的RSRP值，Qrxlevmin和Qrxlevminoffset都是在SIB中配置的小区驻留的最小接收电平，Pcompensation是取终端的上行最大可使用的发射功率减去终端最大射频输出功率的差与0之中的最大值。
R准则：Rs＝Qmeas,s+Qhysts，Rn＝Qmeas,n-Qoffsetn，Rn>Rs
其中，Qmeas,s为服务小区的RSRP值，Qhysts为小区重选滞后延迟值，Qmeas,n为相邻小区的RSRP值，Qoffsetn为服务小区与相邻小区之间的偏置值，Qhysts和Qoffsetn可以通过SIB获取。
对于服务小区和相邻小区的优先级相同的情况，包括同频小区重选和异频小区重选两种的情况。
当Srxlev≤SintraSearch，启动同频小区重选，若相邻小区满足Rn>Rs，持续时长大于或等于Treselection，则终端重选至该同优先级同频小区。
当Srxlev≤SnonintraSearch，启动异频小区重选，当若邻小区满足Rn>Rs，持续时长大于或等于Treselection，则终端重选至同优先级同频小区。
其中，SintraSearch为同频测量门限，SnonintraSearch为异频测量门限，Treselection为时间门限值，SintraSearch、SnonintraSearch、Treselection可以通过SIB获取。
若相邻小区的优先级高于服务小区的优先级时，且Srxlev≥Threshx,high，持续时长大于或等于Treselection，终端重选至高优先级小区。
其中，Threshx,high为高优先级重选门限。
若相邻小区的优先级低于服务小区时，且Srxlev≤SnonintraSearch，启动异频异***测量，当低优先级的相邻小区的Srxlev≥Threshx,low，且服务小区的Srxlev≤Threshserving,low，持续时长大于或等于Treselection，则UE重选至低优先级小区。
其中，Threshx,low为低优先级重选门限，Threshserving,low为服务频点低优先级重选门限。
符合S准则和R准则的相邻小区为候选服务小区。
应理解，终端及SIB获取的各参数的方式可以采用现有技术手段，在此不再过多赘述。
S12，基于各候选服务小区对应的当前时刻的RSRP值和在先时刻的RSRP值，获得各候选服务小区对应的方向指示参数。
其中，方向指示参数用于表征对应的候选服务小区自在先时刻到当前时刻的RSRP值变化信息。
一实施例中，S12可以包括如下步骤：
S201，针对每一候选服务小区，将该候选服务小区所对应的当前时刻的RSRP值和在先时刻的RSRP值相减，获得该候选服务小区自在先时刻到当前时刻的RSRP值的变化量。
Figure PCTCN2022134615-appb-000001
其中，Δnc,j为候选小区j的RSRP值的变化量，
Figure PCTCN2022134615-appb-000002
为候选服务小区j对应的当前时刻的RSRP值，
Figure PCTCN2022134615-appb-000003
为候选服务小区j对应的距离当前时刻预设时长t的在先时刻的RSRP值。
S202，将变化量除以预设时长，获得该候选服务小区自在先时刻到当前时刻的RSRP 值的平均变化率。
Figure PCTCN2022134615-appb-000004
其中，
Figure PCTCN2022134615-appb-000005
为RSRP值的平均变化率，Δt为自在先时刻到当前时刻的预设时长。
S203，通过函数对平均变化率进行约束，获得约束RSRP变化率。
Figure PCTCN2022134615-appb-000006
其中，F(Q)为函数，函数可以为sigmoid、arctan等等。
需要说明的是，函数要求为随着自变量无限增大或减少，因变量趋于两条不同的平行渐近线。
S204，根据预设的方向因子乘以约束RSRP变化率，获得该候选服务小区的方向指示参数。
其中，方向因子表征单位时间内候选服务小区信号的变化来表征终端的移动方向，具体取值范围与选择的函数有关。
可以理解，通过将各候选服务小区所对应的当前时刻的RSRP值与在先时刻的RSRP值相减，获得RSRP值的变化量，再将该变化量除以在先时刻到当前时刻的预设时长，获得该候选服务小区自在先时刻到当前时刻的RSRP值的平均变化率，考虑到RSPR值的平均变化率可能过大，影响确定目标服务小区的准确性，由此利用函数对平均变化率进行约束，获得约束RSRP变化率，再根据预设的方向因子乘以约束RSRP变化率，以调整约束RSRP变化率的取值，使后续确定目标服务小区的方向指示参数的取值更精确。
S13，根据各候选服务小区在当前时刻的RSRP值以及对应的方向指示参数，确定目标服务小区。
一实施例中，S13包括以下步骤。
S301，根据各候选服务小区对应的当前时刻的RSRP值和方向指示参数，获得各候选服务小区的质量分数。
S302，将质量分数最高的候选服务小区作为目标服务小区。
可以理解，通过各候选服务小区对应的当前时刻的RSRP值和方向指示参数，获取各候选服务小区的质量分数，并将质量分数最高的目候选服务小区作为目标服务小区，使得终端重选的目标服务小区的信号稳定且强度较高。
一实施例中，候选服务小区的SINR值大于预设阈值。
可以理解，考虑到某些情况下的候选服务小区的RSRP值较好，但SINR值较差， 容易影响终端与基站的通信服务质量，由此将候选服务小区的SINR值与预设阈值进行对比，使得最终确定的目标服务小区的SINR值大于预设阈值，保证终端重选的目标服务小区的通信服务质量。
