下面结合附图，对本公开的一些实施例作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
请参照图1，图1为本公开实施例提供的一种用户终端的通信管理方法流程示意图。
如图1所示，该用户终端的通信管理方法包括步骤S101至步骤S103。
S101、确定用户终端当前对应的波束属性。
示例性地，如图2所示，本公开中涉及的通信系统包括用户终端、网元侧和网管侧，用户终端包括但不限于5G移动终端，网元侧包括但不限于基站，网管侧包括但不限于网络管理设备。在目标优化区域部署AAPC(Automatic Antenna Pattern Control，天馈权值自适应)功能，基于AAPC天馈权值自适应技术，将基站小区覆盖空间进行划分，不同的波束覆盖不同的区间。

网元侧获得用户终端对应的频偏信息之后，网元侧将频偏信息上报至网管侧，网管侧获得网元侧上报的用户终端对应的频偏信息。
S1012、根据频偏信息，确定用户终端对应的波束属性。
网管侧获得用户终端对应的频偏信息之后，基于用户终端对应的频偏信息，确定用户终端对应的波束属性。例如，根据用户终端对应的频偏信息，确定用户终端对应的波束属性为高速波束属性或者低速/静止波束属性。
在一些实施例中，根据频偏信息，确定用户终端对应的波束属性，包括：将频偏信息与不同波束属性对应的频偏门限进行比较，确定用户终端对应的波束属性。
示例性地，预先给AAPC提供波束属性对应的频偏门限，以判决不同类型的波束属性。例如，分别设置高速波束属性或者低速/静止波束属性对应的频偏门限区间。
需要说明的是，波束属性对应的频偏门限根据实际应用情况的不同可以有差异，这里不做具体限制。
网管侧获得用户终端对应的频偏信息之后，将用户终端对应的频偏信息与不同波束属性对应的频偏门限进行比较，确定用户终端对应的波束属性为高速波束属性或者低速/静止波束属性。
在一些实施例中，将频偏信息与不同波束属性对应的频偏门限进行比较，确定用户终端对应的波束属性，包括：若频偏信息在低速/静止波束属性对应的频偏门限区间内，则确定用户终端对应的波束属性为低速/静止波束属性；若频偏信息在高速波束属性对应的频偏门限区间内，则确定用户终端对应的波束属性为高速波束属性。
也即，若用户终端对应的频偏信息小于低速/静止波束属性对应的频偏门限上限值且大于低速/静止波束属性对应的频偏门限下限值，则确定用户终端对应的波束属性为低速/静止波束属性。若用户终端对应的频偏信息小于高速波束属性对应的频偏门限上限值且大于高速波束属性对应的频偏门限下限值，则确定用户终端对应的波束属性为高速波束属性。
在另一些实施例中，如图4所示，步骤S101可以包括子步骤S1013和子步骤S1014。
S1013、在用户终端初始接入或者切换接入基站小区时，确定用户终端当前位于的波束覆盖区域。
当用户终端是初始接入或者切换接入基站小区时，网元侧可以根据协议规定波束和接入PRACH(Physical Random Access Channel，物理层随机接入信道)使用的前导码PreambleID关系，检测到用户终端当前对应的PreambleID信息，并根据用户终端当前对应的PreambleID，区分用户终端当前位于的波束覆盖区域。
S1014、根据预设的波束覆盖区域与波束属性的对应关系，确定用户终端当前位于的波束覆盖区域对应的波束属性。
示例性地，网管侧预先设置标记波束覆盖区域与波束属性的对应关系。例如，如图5所示，将覆盖区域进行栅格划分，划分成6个区域：1/2/3/4/5/6，其中，区域1和2为静止栅格区域，相应的覆盖这两个区域的波束的波束属性为静止波束属性；区域3和4为低速栅格区域，相应的覆盖这两个区域的波束的波束属性为低速波束属性；区域5和6为高速栅格区域，相应的覆盖这两个区域的波束的波束属性为高速波束属性。
确定了用户终端当前位于的波束覆盖区域，即可确定用户终端当前位于的波束覆盖区 域对应的波束属性。例如，若确定用户终端当前位于的波束覆盖区域为图5中的区域1，则确定用户终端当前对应的波束属性为静止波束属性。又如，若确定用户终端当前位于的波束覆盖区域为图5中的区域5，则确定用户终端当前对应的波束属性为高速波束属性。
S102、根据预设的波束属性与资源策略的映射关系，确定用户终端的波束属性对应的资源策略。
在预设的波束属性与资源策略的映射关系中，不同的波束属性对应不同的资源策略。示例性的，低速/静止波束属性对应的资源策略包括SRS/CSI(Channel State Information，信道状态信息)配置为第一周期、DMRS配置为第一数量符号，高速波束属性对应的资源策略包括SRS/CSI配置为第二周期、DMRS配置为第二数量符号；第一周期长于第二周期，第一数量小于第二数量。例如，低速/静止波束属性对应的资源策略中，第一数量符号配置为单符号或者2符号；高速波束属性对应的资源策略中，第二数量符号配置为2符号或者3符号甚至4符号。
S103、将资源策略发送至网元侧，以供网元侧基于资源策略，对用户终端进行资源配置。
网管侧确定了用户终端的波束属性对应的资源策略后，将该资源策略发送至网元侧，网元侧基于该资源策略，对用户终端进行资源配置。
例如，若确定用户终端的波束属性对应的资源策略为低速/静止波束属性对应的资源策略，则采用低速/静止波束属性对应的资源策略分配无线资源，包括但不限于SRS/CSI配置为第一周期(长周期)，DMRS配置为单符号或者2符号，从而将更多的空口资源留给业务信道，承载更多的信息、提升频谱传输效率。
又如，若确定用户终端的波束属性对应的资源策略为高速波束属性对应的资源策略，则采用高速波束属性对应的资源策略分配无线资源，包括但不限于SRS/CSI配置为第二周期(短周期)，从而更快的跟踪信道变化情况；DMRS配置为2符号或者3符号甚至4符号，给用户终端配置较多的导频符号，可以提升高速场景下用户终端的解调性能。
示例性地，对于高速波束属性对应的用户终端，网元侧上行解调时进入频率偏移补偿流程，根据之前统计得知的频率偏移补偿范围，进行频率偏移补偿处理，能更精准的进行解调计算。网元侧在下行处理过程，也会根据频率偏移补偿范围和上行处理过程中的频率偏移结果相应的进行预补偿发送下行业务数据，这样的网元侧预补偿处理，可以有效的抵消空口传输过程产生的频谱，提升用户终端的解调能力，并且提升了通信系统的鲁棒性。
在一些实施例中，预设波束属性与功控策略的映射关系，不同的波束属性对应不同的功控策略。除了按照上述方式对用户终端进行资源配置以外，还可以根据用户终端的波束属性对应的功控策略，对用户终端进行功控管理。
在一些实施例中，用户终端的通信管理方法还包括：获取网元侧上报的用户终端的通信测量数据；根据通信测量数据，确定用户终端当前对应的调度策略；将调度策略发送至网元侧，以供网元侧基于调度策略，对用户终端进行通信参数调整。
示例性地，通信测量数据包括但不限于RSRP(Reference Signal Receiving Power，参考信号接收功率)、DOA(Direction of Arrival，到达方位角)等数据。网元侧检测获得用户终端对应的通信测量数据后，将RSRP、DOA等通信测量数据上报至网管侧。网管侧获得网元侧上报的RSRP、DOA等通信测量数据之后，对RSRP、DOA等通信测量数据进行统计分类，计算得到用户终端对应的通信参数权值，也即用户终端当前的最优权值，确定用户终端当前对应的调度策略。
示例性地，调度策略包括但不限于水平/垂直波瓣宽度权值、方向角权值、下倾角权值、波束数量权值、波束属性权值等。
之后，网管侧将调度策略发送至网元侧，网元侧基于获得的调度策略，对用户终端进行通信参数调整。示例性的，通信参数调整包括以下至少一项：水平/垂直波瓣宽度调整；方向角/下倾角调整；波束数量调整；以及波束属性调整。
例如，根据调度策略中的水平/垂直波瓣宽度权值，对水平/垂直波瓣宽度进行调整。又如，根据调度策略中的方向角权值，对方向角进行调整。再如，根据调度策略中的下倾角权值，对下倾角进行调整。
在一些实施例中，预设周期时间，根据预设的周期时间，周期性地确定用户终端对应的资源策略/调度策略/功控策略，对用户终端进行通信参数调整、资源配置、功控管理等。需要说明的是，该周期时间可根据实际情况进行灵活设置，在此不做具体限制。
示例性地，网元侧根据用户终端对应的资源策略/调度策略/功控策略，对用户终端进行管理后，对管理效果进行评估，评估准则包括波束覆盖范围、用户终端数量、用户体验速率等评估要素。根据评估结果判定资源策略/调度策略/功控策略是否更新或回退。例如，若评估结果达到预设要求，则将资源策略/调度策略/功控策略更新；若评估结果未达到预设要求，则将资源策略/调度策略/功控策略退回，以便重新确定资源策略/调度策略/功控策略进行更新。
下面，基于图2所示的通信系统，对用户终端的通信管理的流程进行简要说明，如图6所示，进行用户终端的通信管理的流程包括如下步骤Step1至步骤Step5。
Step1：网元侧获得RSRP、DOA、频偏信息，并上报至网管侧。
Step2：网管侧根据RSRP、DOA、频偏信息，确定通信参数权值以及波束属性，获得对应的资源策略/调度策略，并发送至网元侧。
Step3：网元侧将资源策略/调度策略生效，对用户终端进行管理。
Step4：网管侧进行效果评估，并将评估结果发送至网元侧。
Step5：网元侧根据评估结果，将资源策略/调度策略更新或回退。
这样，网元侧对不同波束属性的波束覆盖区域的用户终端进行差别化调度处理和资源配置处理，比如，针对处在高速波束属性的波束覆盖区域的用终端户，配置短周期闭环反馈资源，增加DMRS数量等适合高速移动用户终端的调度处理方案，给用户终端配置较多的导频符号，提升高速场景下用户终端的解调性能。又如，针对处于静止或低速波束属性的波束覆盖区域的用户终端，配置长周期闭环反馈资源，减少DMRS数量等适合静止或低速移动用户终端的调度处理方案，将更多的空口资源留给业务信道，承载更多的信息、提升频谱传输效率。
上述实施例中，通过确定用户终端当前对应的波束属性，根据预设的波束属性与资源策略的映射关系，确定用户终端的波束属性对应的资源策略，然后将确定的资源策略发送至网元侧，网元侧基于获得的资源策略，对用户终端进行资源配置，也即实现针对不同波束属性的波束覆盖区域的用户终端，进行差别化资源配置调度处理，从而提升了用户终端的解调性能。
