Description

乒乓切换抑制方法、装置、终端及可读存储介质 技术领域
本申请涉及通信技术领域，具体而言，涉及一种乒乓切换抑制方法、装置、终端及可读存储介质。
背景技术
LTE(Long Term Evolution，长期演进)网络切换时需要UE(User Equipment，用户终端)上报测量的结果(比如RSRP(Reference Signal Receiving Power，参考信号接收功率)、RSRQ(Reference Signal Receiving Quality，参考信号接收质量)等)，不同的上报事件会触发终端不同的切换类型，例如A3事件上报会触发同频切换，B1事件上报会触发异系统切换等。
现有技术中，在实际LTE网络中，一旦终端所处位置的LTE小区信号稍微波动，就会满足A3事件上报门限，然后终端将A3事件测量报告上报给网络，由网络发起小区切换。然而，测量信号很容易受到终端的方向或是用户手持终端的位置的影响，比如只要稍微挡住移动终端底部或者顶部、终端的手持方向发生变化，测量信号便会受到影响，从而导致终端在服务小区和邻区之间来回切换，即乒乓切换，导致用户体验差。

具体实施方式
下面将结合本申请实施例中附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本申请实施例的组件可以以各种不同的配置来布置和设计。
因此，以下对在附图中提供的本申请的实施例的详细描述并非旨在限制要求保护的本申请的范围，而是仅仅表示本申请的选定实施例。基于本申请的实施例，本领域技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明的是，术语“第一”和“第二”等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
本申请实施例提供的技术方案，涉及一种通信系统，如图1所示，该通信系统包括网络侧和用户侧，用户侧包括终端100，也可称为移动台(mobilestation，MS)；网络侧包括基站200(NodeB)，以及基站控制器300(Base Station Controller，BSC)。
在LTE系统或者5GNR(New Radio，新空口)系统中，网络通过RRC(Radio Resource Control，无线资源控制)信令向连接状态的终端100发送测量配置信息，终端100根据测量配置信息中指示的测量对象、上报配置等参数侦测邻区的信号状态，或者根据网络指示进行邻区系统信息内容的读取，当满足一定的触发条件时进行测量上报的评估，如果满足上报条件，终端100将填写测量上报信息并反馈给网络侧，使得网络侧对终端100进行小区切换或者完善邻小区类关系列表。
以A3事件为例，当终端100测量到LTE同频/异频邻区信号强度高于当前服务小区信号强度满足以下A3条件且满足A3条件持续TTT(Time to trigger，触发时间)时，终端100将 上报A3给网络侧。网络侧收到A3后，给终端100下发切换命令让终端100切换到A3上报的对应的邻区。邻区是指与当前服务小区邻近的小区。示例性地，A3条件为：
Mn+Ofn+Ocn-Hys>Mp+Ofp+Ocp+Off；
其中，Mn为邻区的信号强度测量结果，Ofn为邻区频率的特定频率偏置，Ocn为邻区的小区特定偏移量，Hys为A3事件迟滞参数，Mp为当前服务小区的信号强度测量结果，Ofp为当前服务小区的特定频率偏置，Ocp为当前服务小区的小区特定偏移量，Off为A3事件的偏置参数。
为了应对背景技术部分所述的乒乓切换的问题，本申请实施例提供一种乒乓切换抑制方法、装置、终端100及可读存储介质，以避免或减少终端100在小区间发生乒乓切换。
请参阅图2，为本申请提供的乒乓切换抑制方法的流程图。该乒乓切换抑制方法包括：
S201，当检测到终端100由源服务小区切入当前服务小区时，获取切换服务小区的时间、当前服务小区的服务次数。
终端100由源服务小区切入当前服务小区是指终端100从源服务小区接入网络变化为从当前服务小区接入网络的过程。其中，当前服务小区表示当前状态下终端100网络所处的小区；源服务小区表示在切换至当前服务小区前终端100的网络所处的小区；切换服务小区的时间是指终端100由源服务小区切换至当前服务小区的时刻。当前服务小区的服务次数为终端100从邻区切换至当前服务小区的次数。具体地，当终端100由邻区切换至当前服务小区时，该当前服务小区的服务次数均便加1。
需要说明的是，邻区是相对于当前服务小区而言的，邻区通常是由网络侧配置的，并且会发送给终端100，终端100可以依据网络配置测量当前服务小区与邻区的信号质量，当前服务小区可以配置有多个邻区；在本实施例中，邻区包括上述源服务小区。
在一种可选的实施方式中，在每次终端100进行小区切换时，终端100还可以获取切换前后的小区ID，并将小区ID与切换时间与各个这些小区的服务次数进行关联，便于终端100进行查询。
在一种可选的实施方式中，终端100还会在接入每个小区时，获取并记录该小区的物理层上行以及下行的平均误码率。优选地，该小区的物理层上行以及下行的平均误码率可以与该小区的ID相关联。
S202，判断当前服务小区的服务次数是否大于或等于预设定的切换次数门限值，如果否，则重新执行S201；如果是，则执行S203。
通过判断当前服务小区的服务次数是否大于或等于预设定的切换次数门限值，能够初步确定终端100是否存在多次小区切换的情况。若当前服务小区的服务次数大于或等于预设定的切换次数门限值，表明终端100多次在当前服务小区和邻区之间切换，有可能存在频繁的乒乓切换的情况，但需要进一步获取切换频率才能确定；若当前服务小区的服务次数小于预设定的切换次数门限值，则表明终端100并未频繁切换小区，因而需要继续检测。
需要说明的是，该预设定的切换次数门限阈值可以根据经验进行设置，可以但不仅限于2、3、4等任何数字。
当当前服务小区的服务次数小于预设定的切换次数门限值，重新执行S201，从而持续检测终端100是否再次由邻区切换至当前服务小区，且每检测到一次终端100由邻区切换至当前服务小区，令当前服务小区的服务次数加1，并记录终端100由邻区切换至当前服务小区的时间。
在当前服务小区的服务次数小于预设定的切换次数门限值时，表明终端100并未频繁切换小区，因而继续检测终端100的小区切换情况。例如，终端100在一段时间内的小区切换情况如表1所示：
Figure PCTCN2021108028-appb-000001
以源服务小区为Cell C，当前服务小区为Cell B为例，终端100获取的切换时间为T7，并根据当前服务小区的ID(即Cell B)查询得到上一次切换至该当前服务小区时的服务次数为3，从而此次直接在3的基础上加1，从而确定当前服务小区(Cell B小区)的服务次数为4。
需要强调的是，只要发生由邻区切换至当前服务小区的情况，无论邻区是否为该源服务小区，当前服务小区的服务次数均加1。例如，源服务小区为Cell C，从而终端100由Cell C(源服务小区)切换为Cell B时，当前服务小区(Cell B小区)的服务次数加1；但根据表1可知，终端100在由Cell A(非源服务小区)切换为Cell B时，当前服务小区(Cell B小区)的服务 次数仍然会加1。
S203，获取基准时间，基准时间为终端100第n次由邻区切换至当前服务小区的时间，其中，n＝S+1-Th，S为当前服务小区的服务次数，Th为预设定的切换次数门限值。
在当前服务小区的服务次数大于或等于预设定的切换次数门限值时，表明终端100多次在当前服务小区和邻区之间切换，此时进一步获取基准时间，用于衡量终端100进行小区切换的频率。
需要说明的是，该基准时间为终端100第n次由邻区切换至当前服务小区的时间，也可以理解为终端100在当前服务小区的服务次数为n时对应的切换服务小区的时间。
请参阅表1，以源服务小区为Cell C、当前服务小区为Cell B、预设定的切换次数门限值为3为例，当当前服务小区的服务次数为4时，确定n＝4+1-3＝2，也即基准时间为终端100第2次由邻区切换至当前服务小区的时间，也可以认为是当前服务小区的服务次数为2时对应的切换服务小区的时间，从而确定基准时间为T3。
S204，判断切换至当前服务小区的切换服务小区的时间与基准时间之间的时间差是否小于预设定的时间门限值，如果是，则执行S205；如果否，则重新执行S201。
若切换服务小区的时间与基准时间之间的时间差小于预设定的时间门限值，表明终端100在一段时间内的小区切换频率较高，从而确定终端100在当前服务小区存在频繁的乒乓切换。该预设定的时间门限值可以根据经验进行设置，并且与预设定的切换次数门限阈值配合设置。
若切换服务小区的时间与基准时间之间的时间差大于或等于预设定的时间门限值，表明终端100在一段时间内的小区切换频率还不足以形成频繁的乒乓切换，从而继续检测终端100的小区切换情况。其中，频繁的乒乓切换是指终端100在一段时间内的小区切换频率高于预定频率。
例如，预设定的切换次数门限值为3，在表1中，在T5时刻当前服务小区(Cell B小区)的服务次数为3次，从而进一步获取基准时间为终端100第一次由邻区切换至当前服务小区Cell B的时间，即为T1，从而时间差为T5-T1，但时间差T5-T1大于预设定的时间门限值，从而继续检测小区切换情况，并检测到在T7时刻终端100再次由邻区(Cell C)切换至当前服务小区Cell B，此时当前服务小区(Cell B小区)的服务次数为4次，从而进一步获取基准时间为终端100第二次由邻区切换至当前服务小区Cell B的时间，即为T3，从而时间差为T7-T3，若时间差T7-T3大于或等于预设定的时间门限值，便继续检测小区切换情况，若时间差T7-T3小于预设定的时间门限值，便确定终端100在当前服务小区Cell B存在频繁的乒乓切换，需要 进行乒乓抑制。
S205，确定终端100在当前服务小区存在高于预定频率的乒乓切换。
为了保证用户体验，在确定终端100在当前服务小区存在高于预定频率的乒乓切换时，便会对当前服务小区测量事件上报增加额外的限制条件，以抑制乒乓切换，使得终端100能够驻留在传输品质较好的小区。
S206，根据预先获取的每个小区的平均误码率确定每个小区对应的传输品质分数，其中，小区包括当前服务小区以及终端100已经接入过的邻区。
需要说明的是，终端100在接入每个小区时，便会获取该小区的平均误码率。也即，终端100需要确定每个其接入过的小区(包括当前服务小区以及邻区)的传输品质参数。
可以理解地，平均误码率包括上行平均误码率以及下行平均误码率。因而请参阅图3，为S206的具体流程图。该S206包括：
S2061，根据上行平均误码率确定第一分数偏差。
其中，第一分数偏差用于表征由上行平均误码率而损失的分数。因此，由于上行平均误码率越高则第一分数偏差越高。
在一种可选的实施方式中，若上行平均误码率小于或等于预设定的第一上行阈值，则确定第一分数偏差为预设定的第一分数值；若上行平均误码率大于第一上行阈值且小于或等于预设定的第二上行阈值，则确定第一分数偏差为预设定的第二分数值；若上行平均误码率大于第二上行阈值，则确定第一分数偏差为预设定的第三分数值；其中，预设定的第一上行阈值小于预设定的第二上行阈值，第一分数值、第二分数值、第三分数值依次增大。
例如，该第一上行阈值可以为10％，第二上行阈值为20％。第一分数值为0分，第二分数值为5分，第三分数值为10分。当然，在其他实施方式中，该第一上行阈值、第二上行阈值、第一分数值、第二分数值、第三分数值也可以为其他值，在此不做具体限制。
需要说明是，在其他实施方式中，还可以更加细分上行平均误码率(例如设置第一上行阈值、第二上行阈值、第三上行阈值、第四上行阈值等)，并对应设置更多不同的分数偏差，在此不做具体限制。
S2062，根据下行平均误码率确定第二分数偏差。
第二分数偏差用于表征由下行平均误码率而损失的分数。因此，由于下行平均误码率越高则第二分数偏差越高。
在一种可选的实施方式中，若下行平均误码率小于或等于预设定的第一下行阈值，则确定 第二分数偏差为预设定的第四分数值；若下行平均误码率大于第一下行阈值且小于或等于预设定的第二下行阈值，则确定第二分数偏差为预设定的第五分数值；若下行平均误码率大于第二下行阈值，则确定第二分数偏差为预设定的第六分数值；其中，预设定的第一下行阈值小于预设定的第二下行阈值，第四分数值、第五分数值、第六分数值依次增大。
例如，该第一下行阈值可以为10％，第二下行阈值为20％。第四分数值为0分，第五分数值为5分，第六分数值为10分。当然，在其他实施方式中，该第一下行阈值、第二下行阈值、第四分数值、第五分数值、第六分数值也可以为其他值，在此不做具体限制。
需要说明是，在其他实施方式中，还可以更加细分下行平均误码率(例如设置第一下行阈值、第二下行阈值、第三下行阈值、第四下行阈值等)，并对应设置更多不同的分数偏差，在此不做具体限制。
S2063，在预先设定的基准分数上减去第一分数偏差及第二分数偏差得到传输品质分数。
例如，预先设定的基准分数为100分，若某小区的第一分数偏差为5分，第二分数偏差为10分，则该小区的传输品质分数即为75分。
需要说明的是，每个小区的传输品质分数均可采用S2061～S2063所述的方式进行确定。
S207，从邻区中确定目标小区，其中，目标小区为邻区中传输品质分数低于当前服务小区的传输品质分数的小区。
在确定每个小区的传输品质分数以后，将邻区中传输品质分数低于当前服务小区的传输品质分数的小区确定为目标小区。
例如，在S206中确定当前服务小区的传输品质分数为90分，邻区Cell A的传输品质分数为90分、邻区Cell C的传输品质分数为80分，从而将邻区Cell C确定为目标小区。
S208，获取目标小区的信号质量参数以及当前服务小区的信号质量参数。
其中，由于信噪比较能衡量小区的传输性能，因而目标小区的信号质量参数包括第一信噪比及第一参考信号接收功率，当前服务小区的信号质量参数包括第二信噪比及第二参考信号接收功率。
可以理解地，终端100可以直接侦测邻区的信号状态从而获取目标小区的第一信噪比及第一参考信号接收功率。
S209，根据目标小区的信号质量参数以及当前服务小区的信号质量参数确定是否限制上报包含目标小区的测量事件。
具体地，当第一信噪比与预设定的信噪比偏移值的差值大于第二信噪比，且第一参考信号 接收功率与预设定的参考信号接收功率偏移值的差值大于第二参考信号接收功率时，正常上报包含目标小区的测量事件。
当第一信噪比与预设定的信噪比偏移值的差值小于或等于第二信噪比，或者第一参考信号接收功率与预设定的参考信号接收功率偏移值的差值小于或等于第二参考信号接收功率时，限制上报包含目标小区的测量事件。
也即，当满足：Cell 目标_RSRP-low qos_RSRP_offset＞Cell 当前_RSRP以及Cell 目标_SNR-low qos_SNR_offset＞Cell 当前_SNR时，可以正常上报包含目标小区的测量事件；否则限制上报包含目标小区的测量事件。
其中，Cell 目标_SNR为第一信噪比，low qos_SNR_offset为预设定的信噪比偏移值，Cell 当前_SNR为第二信噪比，Cell 目标_RSRP为第一参考信号接收功率，low qos_RSRP_offset为预设定的参考信号接收功率偏移值，Cell 当前_RSRP为第二参考信号接收功率。
需要说明的是，上述正常上报包含目标小区的测量事件是指，在满足Cell 目标_RSRP-low qos_RSRP_offset＞Cell 当前_RSRP以及Cell 目标_SNR-low qos_SNR_offset＞Cell 当前_SNR的前提下，一旦目标小区的信号强度满足正常上报条件(如A1/A2/A3的上报条件)，就能上报对应的测量事件。
相应地，限制上报包含目标小区的测量事件可以指，若不满足Cell 目标_RSRP-low qos_RSRP_offset＞Cell 当前_RSRP以及Cell 目标_SNR-low qos_SNR_offset＞Cell 当前_SNR的条件，即使该目标小区的信号强度满足正常上报条件(如A1/A2/A3的上报条件)，也无法上报对应的测量事件。
在具体的实施例中，测量事件例如可以是A3事件、A4事件或A5事件。
因而，本申请通过对存在频繁乒乓切换的小区的测量事件上报增加额外的限制条件，以抑制乒乓切换，使得终端100能够驻留在传输品质较好的小区，有效提升用户体验。上述乒乓切换抑制方法4G或5G系统。
