Description

一种小区重选方法及终端设备
本申请要求于2021年2月25日提交国家知识产权局、申请号为202110210605.3、发明名称为“一种小区重选方法及终端设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种小区重选方法及终端设备。
背景技术
目前，4G(4thgeneration)和5G(5thgeneration)网络中的一些小区(cell)可以由多家运营商共同建立和运营。例如，如图1所示，地区1中包括由运营商A建立的小区101、由运营商B建立的小区102。并且，地区1中还可以包括由运营商A和运营商B共同建立的共建小区103。其中，手机在小区101中的工作频点为频点A，而手机在小区102与共建小区103中的工作频点均为频点B。
在这种场景下，签约运营商A的手机进入小区101后，可将小区101作为服务小区驻留在小区101中。当手机驻留在小区101时，可以执行小区重选(cell reselection)流程。其中，小区重选流程是指手机在空闲模式(idle)下通过监测邻区和当前服务小区的信号质量以选择一个最好的小区提供服务信号的过程。例如，手机向小区102移动的过程中，如果检测到小区102的信号质量大于预设门限，则手机可通过解析来自小区102的系统消息获取小区102的PLMN。如果小区102的PLMN(Public Land Mobile Network，公共陆地移动网)与当前服务小区(即小区101)的PLMN不互为EPLMN(Equivalent PLMN，等效PLMN)，则手机可按照3GPP的相关协议在一段时间(例如300s)内禁用与小区102对应的频点B。
但是，由于共建小区103的频点与小区102的频点相同(均为频点B)，这使得手机在禁用频点B的这段时间内，如果手机移动至共建小区103，手机也无法通过小区重选流程接入共建小区103。这样，手机无法从共建小区103获得信号质量较好的服务，同时，手机的移动性能也随之降低。
发明内容
本申请提供一种小区重选方法及终端设备，可使终端设备通过小区重选流程在共建小区中获得更好的信号质量，提高终端设备的移动性能。
第一方面，本申请提供一种小区重选方法，包括：终端设备可驻留至第一小区，第一小区对应第一频点；在第一小区中，第一频点对应第一PLMN；当终端设备检测到第二小区(第二小区为第一小区的邻区)满足小区重选条件，且第二小区的第二PLMN与第一PLMN不是EPLMN时，终端设备不执行重选到第二小区的动作，且将第二小区添加至禁用名单中；其中，第二小区对应的第二频点与上述第一频点不同；在第二小区中，第二频点对应第二PLMN；例如，第一PLMN可以是运营商A的PLMN，第二PLMN可以是运营商B的PLMN。由于终端设备是以小区为粒度将第二小区添加 至禁用名单中，而不是以频点为粒度将第二小区的第二频点添加至禁用名单中，这使得当后续终端设备检测到第三小区满足小区重选条件，且第三小区的第三PLMN与第一PLMN是EPLMN时，即使第三小区与第二小区的频点相同，终端设备仍然可以执行重选到第三小区的动作；其中，第三小区可以对应多个运营商的PLMN，例如，第三小区的第三PLMN可以包括第一PLMN和第二PLMN。
可以看出，虽然上述第三小区与第二小区的频点相同，但由于终端设备可以以小区为粒度设置小区重选时的禁用名单，因此，当终端设备禁用第二小区时，不会影响对相同频点的第三小区的小区重选流程，使终端设备在存在能够通过小区重选流程顺利接入与禁用的小区同频的其他小区，从而获得信号质量较好的服务信号，并增强终端设备的移动性能。
在一种可能的实现方式中，在终端设备驻留至第一小区之后，还包括：终端设备对第一小区的至少一个邻区执行小区测量；当第二小区的测量结果满足小区重选条件时，终端设备获取第二小区的第二PLMN。也就是说，终端设备可以先通过小区测量筛选出满足小区重选条件的第二小区，再通过比较两个小区的PLMN确定是否能够重选该小区。
或者，终端设备也可以先获取第一小区邻区的PLMN，确定与第一PLMN不是EPLMN的第二小区的第二PLMN，再在小区重选时确定第二小区是否满足小区重选条件。
在一种可能的实现方式中，终端设备获取第二小区的第二PLMN，包括：终端设备获取第二小区的SIB消息；终端设备通过解析第二小区的SIB消息，可得到第二小区的第二PLMN。
在一种可能的实现方式中，终端设备对第一小区的至少一个邻区执行小区测量，包括：终端设备获取第一小区的网络设备发送的配置信息，该配置信息中包括至少一个测量目标和测量门限；例如，测量目标可以包括第二小区的小区标识、频点等信息；测量门限可以包括对服务小区的测量门限和/或对测量目标的测量门限，进而，终端设备可按照上述配置信息执行小区测量，并根据测量门限确定测量目标中的各个小区是否满足小区重选条件。
在一种可能的实现方式中，终端设备将第二小区添加至预设的禁用名单中，包括：终端设备将第二小区的小区标识和第二频点添加至禁用名单中。
在一种可能的实现方式中，当终端设备检测到第二小区满足小区重选条件，且第二小区的第二PLMN与第一PLMN不是EPLMN时，方法还包括：终端设备获取终端设备的移动速度、屏幕状态、电量以及第一小区的信号质量中的至少一个参数。
此时，终端设备将第二小区添加至预设的禁用名单中，具体可以包括：当第一小区的信号质量小于预设的信号质量阈值时，终端设备可将第二小区添加至预设的禁用名单；和/或，当终端设备的移动速度大于预设的速度阈值时，终端设备可将第二小区添加至预设的禁用名单；和/或，当终端设备处于亮屏状态时，终端设备可将第二小区添加至预设的禁用名单；和/或，当终端设备的电量大于预设的电量阈值时，终端设备可将第二小区添加至预设的禁用名单。当然，终端设备还可以结合上述多项参数，设置将第二小区添加至预设的禁用名单的触发条件。
在一种可能的实现方式中，当终端设备检测到第二小区满足小区重选条件，且第二小区的第二PLMN与第一PLMN不是EPLMN时，方法还包括：终端设备确定第一小区归属的第一运营商与第二小区归属的第二运营商具有共建关系。一般，具有共建关系的小区会出现与某一共建方的小区同频的情况，因此，终端设备获取到第二小区的第二PLMN后，可查询其对应的运营商是否与自身签约的运营商有共建关系。若有共建关系，则终端设备可将第二小区添加至预设的禁用名单，避免后续共建的同频小区无法参与终端设备的小区重选。
在一种可能的实现方式中，在终端设备将第二小区添加至预设的禁用名单中之后，还包括：终端设备检测到第二小区的信号后，终端设备通过禁用名单可丢弃第二小区的信号，使第二小区无法参与终端设备的小区重选。
在一种可能的实现方式中，终端设备检测第二小区满足小区重选条件，包括：当第二小区的测量结果大于第一门限，且第一小区的测量结果小于第二门限时，说明第二小区的信号质量较好而服务小区的信号质量较差，此时，终端设备可确定第二小区满足小区重选条件；类似的，终端设备检测第三小区满足小区重选条件，包括：当第三小区的测量结果大于第一门限，且第一小区的测量结果小于第二门限时，终端设备确定第三小区满足小区重选条件。当然，终端设备还可以结合第二小区的频点的优先级、终端设备在第一小区的驻留时间等一项或多项确定第二小区是否满足小区重选条件。
在一种可能的实现方式中，当终端设备检测到第三小区满足小区重选条件后，还包括：终端设备获取第三小区的第三PLMN，例如，终端设备可通过解析第三小区的SIB消息，获取第三小区的第三PLMN；当第三小区为多个运营商的共建小区时，第三小区的第三PLMN包括多个运营商的PLMN；此时，当第三PLMN中的一个PLMN与第一PLMN是EPLMN时，终端设备可确定第三PLMN与第一PLMN是EPLMN。
第二方面，本申请提供一种小区重选方法，包括：终端设备驻留至第一小区，第一小区对应第一频点；终端设备根据各个小区的频点可以确定对应小区为4G小区或5G小区，当终端设备检测到5G小区中的第二小区(第二小区为NSA小区)满足小区重选条件，且第二小区不允许重选到同频的另一个小区时，终端设备不执行重选到第二小区的动作，且将第二小区添加至预设的禁用名单中；其中，第二小区对应的第二频点与第一频点不同；后续，当终端设备检测到5G小区中的第三小区(第三小区为SA小区)满足小区重选条件，且第三小区的PLMN与第一小区的PLMN是EPLMN时，终端设备可执行重选到第三小区的动作；第三小区的频点与第二频点相同。
与第一方面类似的，虽然SA小区与NSA小区的频点相同，但由于终端设备可以以小区为粒度设置小区重选时的禁用名单，因此，当后续终端设备检测到与第二小区的频点相同的SA小区(即第三小区)满足小区重选条件，终端设备仍然可以按照正常的小区重选流程接入第三小区，使终端设备在同频的SA小区和NSA小区中移动时，能够通过小区重选流程顺利接入与禁用的NSA小区同频的SA小区，从而获得信号质量较好的服务信号，并增强终端设备的移动性能。
在一种可能的实现方式中，在终端设备驻留至第一小区之后，还包括：终端设备对第一小区的至少一个邻区执行小区测量；当第二小区的测量结果满足小区重选条件 时，终端设备确定第二小区是否为NSA小区；若第二小区为NSA小区，则终端设备确定第二小区不允许重选到同频的另一个小区。
示例性的，终端设备确定第二小区是否为NSA小区，包括：终端设备获取第二小区的SIB消息；当第二小区的SIB消息中没有设置与第二小区的PLMN对应的TAC时，终端设备可确定第二小区为NSA小区；否则，终端设备可确定第二小区为SA小区。
示例性的，终端设备确定第二小区不允许重选到同频的另一个小区，包括：终端设备获取第二小区的MIB消息；当第二小区的MIB消息中设置了不允许重选到同频的另一个小区的选项时，终端设备可确定第二小区不允许重选到同频的另一个小区。
也就是说，当终端设备确定出第二小区为5G小区中的NSA小区后，触发终端设备禁用第二小区的触发条件，从第一方面中的第二小区的PLMN与第一小区的PLMN不是EPLMN，变为第二小区的MIB消息中配置了不允许同频重选小区的选项。
在一种可能的实现方式中，在终端设备将第二小区添加至预设的禁用名单中之后，还包括：当终端设备检测到第三小区满足小区选择条件，且第三小区的PLMN与第一小区的PLMN是EPLMN时，终端设备执行选择到第三小区的动作。
也就是说，第二方面中的禁用名单不仅适用于后续的小区重选流程，还适用于后续的小区选择流程。这样，当后续终端设备检测到与第二小区的频点相同的SA小区(即第三小区)满足小区选择条件，终端设备仍然可以按照正常的小区选择流程接入第三小区，使终端设备能够通过小区重选流程顺利接入与禁用的NSA小区同频的SA小区，从而获得信号质量较好的服务信号，并增强终端设备的移动性能。
在一种可能的实现方式中，当终端设备检测到第二小区满足小区重选条件，且第二小区不允许重选到同频的另一个小区时，方法还包括：终端设备获取终端设备的移动速度、屏幕状态、电量以及第一小区的信号质量中的至少一个参数。
此时，终端设备将第二小区添加至预设的禁用名单中，包括：当第一小区的信号质量小于预设的信号质量阈值时，终端设备可将第二小区添加至预设的禁用名单；和/或，当终端设备的移动速度大于预设的速度阈值时，终端设备可将第二小区添加至预设的禁用名单；和/或，当终端设备处于亮屏状态时，终端设备可将第二小区添加至预设的禁用名单；和/或，当终端设备的电量大于预设的电量阈值时，终端设备可将第二小区添加至预设的禁用名单。
在一种可能的实现方式中，终端设备将第二小区添加至预设的禁用名单中，包括：终端设备将第二小区的小区标识和第二频点添加至禁用名单中。
第三方面，本申请提供一种终端设备，包括：存储器、通信模块和一个或多个处理器；存储器、通信模块与处理器耦合。其中，存储器用于存储计算机程序代码，计算机程序代码包括计算机指令；当终端设备运行时，该处理器用于执行该存储器存储的一个或多个计算机指令，以使终端设备执行如上述第一方面或第二方面中任一项所述的小区重选方法。
第四方面，本申请提供一种计算机可读存储介质，该计算机可读存储介质包括计算机指令。当计算机指令在终端设备上运行时，使得该终端设备执行如上述第一方面或第二方面中任一项所述的小区重选方法。
第五方面，本申请提供一种计算机程序产品，当所述计算机程序产品在终端设备上运行时，使得终端设备执行如上述第一方面或第二方面中任一项所述的小区重选方法。
可以理解地，上述各个方面所提供的终端设备、计算机可读存储介质以及计算机程序产品均应用于上文所提供的对应方法，因此，其所能达到的有益效果可参考上文所提供的对应方法中的有益效果，此处不再赘述。

具体实施方式
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
为了方便理解本申请实施例的技术方案，首先给出本申请相关技术的简要介绍如下。
PLMN(Public Land Mobile Network，公共陆地移动网)，是指为公众提供陆地移动通信业务目的而建立和经营的网络。其中，PLMN＝MCC(Mobile Country Code，移动国家代码)+MNC(Mobile Network Code，移动网络代码)。不同运营商的PLMN一般不同。
对于一个终端设备来说，通常需要维护几种不同类型的PLMN列表。例如，可将PLMN划分为RPLMN(Registered PLMN，已登记PLMN)、HPLMN(Home PLMN，归 属PLMN)、EPLMN(Equivalent PLMN，等效PLMN)、VPLMN(Visited PLMN，访问PLMN)、UPLMN(User Controlled PLMN，用户控制PLMN)、OPLMN(Operator Controlled PLMN，运营商控制PLMN)以及FPLMN(Forbidden PLMN，禁用PLMN)等。
其中，EPLMN是指与终端设备当前所选择的PLMN处于同等地位的PLMN，其优先级相同。例如，中国移动的PLMN有46000、46002、46007这三个号段。其中，46002相对46000就是EPLMN。
小区(cell)，是指用于为终端设备提供无线通信业务的一片区域，其中，网络设备(例如接入网设备、核心网设备等)在该区域中为终端设备提供无线通信业务。例如，小区可以为蜂窝状的区域。其中，一个网络设备可以管理一个或多个小区。每个小区对应一个小区标识(cell identifier，cell ID)，由该小区标识唯一标识该小区。若终端设备驻留到某个小区，则该小区可以称为该终端设备的驻留小区或服务小区(serving cell)。该服务小区周围、与该服务小区相邻的小区可以称为该服务小区的邻居小区(neighborhood cell)或者邻区。
一般，同一运营商的小区的频点是相同，不同运营商的小区的频点是不同的。例如，小区A和小区B均为运营商A的小区，则小区A和小区B的频点均为频点1，小区A和小区B的PLMN均为PLMN 1。如果小区C为运营商B的小区，则小区C的频点2与频点1一般不同，小区C的PLMN也与小区A(或小区B)的PLMN不同，例如，小区C的PLMN为PLMN 2。
目前，还有一类特殊的小区(例如小区D)，小区D可以向签约多家运营商的终端设备服务。例如，小区D可以是运营商A和运营商B共同建立的小区，小区D的频点为频点2，即小区D为小区C的同频小区，这类小区后续实施例中可称为共建小区。小区D既可以向签约运营商A的终端设备提供服务，还可以向签约运营商B的终端设备提供服务。
其中，小区D的频点可以为上述频点1，也可以为上述频点2。无论小区D的频点为频点1或频点2，小区D的PLMN包括两个，一个是属于运营商A的PLMN(例如上述PLMN 1)，一个是属于运营商B的PLMN(例如上述PLMN 2)。此时，当PLMN 1和PLMN 2中的一个与服务小区的PLMN为EPLMN时，可认为小区D的PLMN与服务小区的PLMN为EPLMN。
需要说明的是，共建小区还可以是三个或者更多个运营商共建的小区，本申请实施例对此不做任何限制。另外，除了通过多个运营商共建小区这种方式使得一个小区可以对应多个运营商外，本领域技术人员还可以根据实际经验或实际应用场景设置一个小区对应多个运营商，以下实施例均以运营商A和运营商B共同建立的共建小区举例说明。
小区重选(cell reselection)流程，是指终端设备在空闲模式(idle)下通过监测邻区和当前服务小区的信号质量以选择一个最好的小区提供服务信号的过程。
示例性的，仍如图1所示，地区1中包括运营商A建立的小区101，小区101的频点为频点A。地区1中还包括运营商B建立的小区102，小区102的频点为频点B。地区1中还包括运营商A和运营商B共同建立的共建小区103，小区103的频点可与 小区102的频点相同，即小区103是与小区102同频的共建小区。终端设备在地区1内移动的过程中，可以通过小区重选流程接入信号质量较好的小区，从而获得信号质量较好的服务。
以终端设备签约运营商A举例，如图2所示，当终端设备位于小区101时，可将小区101作为服务小区驻留在小区101。并且，终端设备在空闲模式下可以测量邻区和当前服务小区的信号质量，从而判断邻区和当前服务小区的信号质量是否满足重选条件(reselection rules)。例如，当检测到小区102的信号质量大于预设值1，且小区101的信号质量小于预设值2(预设值2小于或等于预设值1)时，小区102满足小区重选条件。此时，终端设备可将小区102作为候选小区获取小区102中广播的系统消息1。终端设备解析系统消息1可获得小区102的PLMN，即运营商B的PLMN。由于运营商B的PLMN与运营商A的PLMN(即小区101的PLMN)不是EPLMN，因此，终端设备可按照3GPP协议中36.304 5.2.4.4章节的相关规定，禁用小区102的频点B，禁用时长为300s。也就是说，在这300s内，终端设备无法将频点为频点B的小区作为目标小区进行小区重选，从而降低终端设备的功耗。
其中，3GPP协议中36.304 5.2.4.4章节的相关规定如下：
If the highest ranked cell or best cell according to absolute priority reselection rules is an intra-frequency or inter-frequency cell which is not suitable for a CN type due to being part of the"list of forbidden TAs for roaming"or belonging to a PLMN which is not indicated as being equivalent to the registered PLMN,the UE shall not consider this cell and other cells on the same frequency,as candidates for reselection for the CN type for a maximum of 300s.If the UE enters into state any cell selection,any limitation shall be removed.If the UE is redirected under E-UTRAN control to a frequency for which the timer is running,any limitation on that frequency shall be removed.
但是，在这种场景下，仍如图2所示，后续当终端设备靠近或移动至共建小区103时，由于共建小区103与小区102的频点均为频点B，因此，即使共建小区103的信号质量大于预设值1，且小区101的信号质量小于预设值2(即满足上述小区重选条件)，终端设备也无法将共建小区103作为目标小区接入共建小区103。这样，终端设备仍然驻留在小区101中，使得终端设备的移动性能以及获取到的信号质量均受到影响。
对此，在本申请实施例中，仍以上述场景举例，如图3所示，当终端设备检测到小区102和当前服务小区101的信号质量满足上述小区重选条件后，如果小区102的PLMN(即运营商B的PLMN)与小区101的PLMN(即运营商A的PLMN)不互为EPLMN，则终端设备可将小区102添加至用于小区重选的禁用名单中，而不是将小区102的频点B添加至禁用名单中。
后续，终端设备虽然无法将位于禁用名单的小区102作为目标小区进行小区重选，但是，仍如图3所示，当终端设备检测到共建小区103和当前服务小区(即小区101)的信号质量满足上述重选条件时，由于共建小区103并不在上述禁用名单中，因此，终端设备可继续沿用现有的小区重选流程，将共建小区103作为目标小区接入共建小区103。
这样，虽然共建小区103与小区102的频点相同，但由于终端设备可以以小区为 粒度设置小区重选时的禁用名单，因此，当终端设备在小区重选时禁用不在EPLMN列表的小区102时，不会影响对相同频点的共建小区103的小区重选流程，使用终端设备在这种存在共建小区的场景下移动时，共建小区能够有效向终端设备提供服务信号，增强终端设备的移动性能。
其中，终端设备在小区重选流程中以小区为粒度设置禁用名单的具体方案将在后续实施例中详细阐述，故此处不予赘述。

以下将结合附图详细阐述本申请实施例提供的一种小区重选方法。
如图7所示，本申请实施例提供的一种小区重选方法可包括下述步骤S601-S606：
S601、终端设备驻留至第一小区后，获取网络设备发送的小区重选的配置信息。
以第一小区为运营商A建立的小区举例，如果终端设备签约了运营商A，则终端设备可接入运营商A在各地建立的小区，享受运营商A提供的信号服务。在一些实施例中，运营商A可与其他一个或多个运营商建立合作关系。例如，运营商A可与运营商B共同建立共建小区1，此时，签约运营商A的终端设备可接入共建小区1，签约运营商B的终端设备也可接入共建小区1。
一般，为不同运营商划分的网络频段范围是不同的。例如，运营商A获得的频段范围为频点1-频点2，运营商B获得的频段范围为频点3-频点4。不同运营商可在自身的频段范围内为自身的小区分配一个频点，使得接入对应小区的终端设备在相应的频点下工作。例如，运营商A可在频点1-频点2这一范围内设置第一小区的频点为频点A，那么，接入第一小区的终端设备的工作频点为频点A。又例如，运营商B可在频点3-频点4这一范围内设置第二小区的频点为频点B，那么，接入第二小区的终端设备的工作频点为频点B。对于上述共建小区1，可将共建小区1设置为频点A或频点B。也就是说，共建小区的频点可与参与共建的某一运营商为其小区设置的频点相同。当然，不同运营商的网络频段范围之间也可能出现交叠的情况，本申请实施例对此不做任何限制。
另外，不同通信系统使用的频段范围也是不同的。例如，4G通信系统(也可称为4G网络)使用的频段范围为频段范围1，5G通信系统(也可称为5G网络)使用的频段范围为频段范围2，频段范围2与频段范围1不同。在频段范围1内，各个运营商拥有对应的频段范围；在频段范围2内，各个运营商也拥有对应的频段范围。那么，终端设备可根据各个小区的频点确定对应小区覆盖的是4G网络还是5G网络。
示例性的，在步骤S601中，如图8所述，签约运营商A的终端设备1靠近或进入第一小区701后，可搜索到第一小区701的网络设备1在第一小区701提供的信号。进而，终端设备1可按照现有的小区选择和小区驻留流程在频点A上接入并驻留至第一小区701。例如，终端设备1可先与网络设备1进行下行同步，进而，终端设备1可判断第一小区701是否满足“S准则”(“S准则”为LTE定义的小区选择过程中需要满足的条件)。如果满足“S准则”，则终端设备1可将第一小区701作为服务小区(也可称为驻留小区)进行驻留。
第一小区701的网络设备1可定期检测邻区的频点等小区信息。例如，仍如图8所述，网络设备1可与邻区(例如第二小区702)的网络设备2进行交互，获取第二小区702的频点等小区信息。当终端设备1在第一小区701中驻留时，网络设备1可根据各个邻区的小区信息，将用于小区重选的配置信息发送至终端设备1。例如，网络设备1可通过广播的形式广播上述配置信息。其中，该配置信息中可以包括测量目标(measurement object，MO，也可称为测量对象)、测量门限等参数。
示例性的，上述测量目标可以包括第一小区701的邻区(例如第二小区702、第三小区703等)的频点、小区标识等参数。
示例性的，上述测量门限可以包括用于指示小区信号质量的一项或多项参数的门限值。例如，上述测量门限可以包括：接收信号码功率(received signal code power，RSCP)门限、参考信号接收功率(reference signal receiving power，RSRP)门限、参考信号接收质量(reference signal receiving quality，RSRQ)门限、信噪比(signal noise ratio，SNR)门限、信号与干扰加噪声比(signal to interference plus noise ratio，SINR)门限、参考信号强度指示(reference signal strength indication，RSSI)门限或其他信号质量门限中的一项或多项。
可选的，上述测量门限可以包括针对服务小区(即第一小区701)的测量门限1，还可以包括针对上述测量目标(例如邻区)的测量门限2。
后续，终端设备1可根据接收到的配置信息，对配置信息中的测量目标执行小区测量，并对当前的服务小区执行小区测量，即执行下述步骤S602。
需要说明的是，上述小区重选的配置信息可以是网络设备发送给终端设备的，或者，终端设备也可以根据网络设备的配置或者通知或者指示来确定上述小区重选的配置信息，又或者，上述小区重选的配置信息还可以是协议规定的，本申请实施例对此不做任何限制。
S602、终端设备根据上述配置信息执行小区测量。
仍以上述终端设备1获取到网络设备1发送的小区重选的配置信息举例，该配置信息中的测量目标可以包括频点B的第二小区702。并且，该配置信息中可以包括对服务小区的测量门限1，以及对测量目标的测量门限2。
进而，当终端设备1处于空闲模式(idle)时，可按照上述配置信息测量当前驻留的服务小区(即第一小区701)的信号质量，得到测量结果1。并且，终端设备1可按照上述配置信息测量第二小区702的信号质量，得到测量结果2。需要说明的是，本申请实施中，“测量结果”也可以称为“测量量”或“测量值”，用于表征信号质量，二者可以相互替换，或者，“测量结果”也可以称为“信号质量”。
例如，终端设备1可通过测量以下多种信号中的至少一种获得对应的测量结果。该多种信号包括：下行同步信道、信道状态信息参考信号(channel-state information reference signal，CSI-RS)、解调参考信号(demodulation reference signal，DMRS)、小区参考信号(cell-specific reference signal，CRS)信号、同步信号(synchronization signal，SS)、同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH Block，或者SSB)、或者其它下行信号。
需要说明的是，服务小区或邻区的测量结果与测量门限中参数的类型是一一对应的。例如，如果上述对服务小区的测量门限1中仅包括RSRQ门限，则终端设备1对服务小区的测量结果1中对应的包括RSRQ。又例如，如果上述对第二小区702的测量门限2中包括RSRQ门限和RSRP门限，则终端设备1对第二小区702的测量结果2中对应的包括RSRQ和RSRP。
另外，上述配置信息的测量目标还可以包括第三小区703等其他测量目标。此时，终端设备1还可以按照上述方法对第三小区703等其他测量目标执行小区测量，本申 请实施例对此不做任何限制。
S603、当第二小区的测量结果满足小区重选条件时，终端设备获取来自第二小区的第一系统消息，第一系统消息中包括第二小区的PLMN。
示例性的，假设终端设备1对服务小区(即第一小区701)执行小区测量后，得到测量结果1；并且，终端设备1对第二小区702执行小区测量后，得到测量结果2。此时，终端设备1可将测量结果1与上述配置信息中的测量门限1对比，并且，终端设备1可将测量结果2与上述配置信息中的测量门限2对比。
当测量结果1小于测量门限1，且测量结果2大于测量门限2时，如图9所示，说明当前终端设备1接收到的第一小区701的信号质量较差，而终端设备1接收到的第二小区702的信号质量较高，此时终端设备1可能靠近或进入第二小区702。
或者，终端设备1也可以先对第一小区701执行小区测量。当第一小区701的测量结果1小于上述测量门限1时，说明终端设备1接收到的第一小区701的信号质量较差，此时，可触发终端设备1对配置信息中的第二小区702执行小区测量，得到测量结果2。如果测量结果2大于上述测量门限2，说明终端设备1可能靠近或进入第二小区702。当然，如果第一小区701的测量结果1大于上述测量门限1，则终端设备1可不对第二小区702执行小区测量，继续驻留在第一小区701。
无论终端设备1采用哪种测量顺序进行小区测量，当测量结果1小于测量门限1，且测量结果2大于测量门限2后，终端设备1可确定第二小区702满足小区重选条件。或者，终端设备1还可以结合第二小区702的频点B的优先级、终端设备1在第一小区701的驻留时间、测量结果1小于测量门限1的持续时间或测量结果2大于测量门限2的持续时间等一项或多项确定第二小区702是否满足小区重选条件。
例如，除了测量结果1小于测量门限1，且测量结果2大于测量门限2之外，如果终端设备1在第一小区701的驻留时间大于预设时间(例如1s)，则终端设备1可确定第二小区702满足小区重选条件。
此时，仍如图9所示，终端设备1可将第二小区702作为本次小区重选的候选小区(candidate for reselection)，获取第二小区702的网络设备2发送的系统消息。例如，该系统消息可以包括SIB(System Information Blocks)消息。
示例性的，第二小区702的网络设备2可以广播的形式发送SIB消息1。终端设备1接收到SIB消息1后，可对SIB消息1进行解析，得到第二小区702的PLMN。如果第二小区702的PLMN与第一小区701的PLMN是等效PLMN(即EPLMN)，例如，第二小区702的PLMN和第一小区701的PLMN均为营运商A的PLMN，说明第二小区702也是营运商A的小区，则终端设备1可按照现有的小区重选流程，将第二小区702作为目标小区进行小区接入。
相应的，如果第二小区702的PLMN与第一小区701的PLMN不是EPLMN，说明终端设备1没有权限接入第二小区702，此时，终端设备1可继续执行下述步骤S604。
S604、若第二小区的PLMN与第一小区的PLMN不是等效PLMN(EPLMN)，则终端设备将第二小区的小区标识以及第二小区的频点添加至预设的禁用名单中。
在步骤S604中，如果第二小区702的PLMN与第一小区701的PLMN不是EPLMN，则终端设备1可根据第二小区702的PLMN，确定第二小区702所属的运营商B与终 端设备1签约的运营商A是否有共建关系。该共建关系是指两个或多个运营商以合作的形式共建有共建小区。例如，终端设备1签约运营商A后，可从运营商A的网络设备中获取与运营商A有共建关系的运营商包括运营商B和运营商C。那么，如果第二小区702的PLMN为运营商B的PLMN，则终端设备1可确定第二小区702所属的运营商B与终端设备1签约的运营商A有共建关系。
当第二小区702所属的运营商B与终端设备1签约的运营商A有共建关系时，可能会出现运营商A与运营商B的共建小区(例如第三小区703)的频点与第二小区702的频点相同的情况。此时，如果因为第二小区702的PLMN与第一小区701的PLMN不是EPLMN，而禁用第二小区702的频点B，则会出现相同频点的第三小区703也无法作为候选小区参与终端设备1的小区重选流程的问题。
对此，在步骤S604中，当第二小区702的PLMN与第一小区701的PLMN不是EPLMN，且第二小区702所属的运营商B与终端设备1签约的运营商A有共建关系时，终端设备1可将第二小区702的小区标识以及第二小区702的频点B添加至预设的禁用名单1中，而不是直接将第二小区702的频点B添加至预设的禁用名单1中。
示例性的，终端设备1可预先为小区重选流程设置禁用名单1。例如，该禁用名单1的初始状态可以为空，即所有满足上述小区重选条件的小区均可作为候选小区参与终端设备1的小区重选流程。当终端设备1通过执行上述小区测量确定出第二小区702满足小区重选条件后，如果第二小区702的PLMN与第一小区701的PLMN不是EPLMN，且第二小区702所属的运营商B与终端设备1签约的运营商A有共建关系，则如表1所示，终端设备1可将第二小区702的cell ID(即小区标识)和第二小区702的频点B添加至禁用名单1中。这样，终端设备1不是以频点为粒度设置小区重选时的禁用名单1，而是以小区为粒度设置小区重选时的禁用名单1，使得后续与第二小区702同频的共建小区仍然可作为候选小区参与终端设备1的小区重选流程。
表1
Figure PCTCN2021127422-appb-000001
可选的，上述禁用名单1中还可以设置对应的禁用时长。例如，当终端设备1将第二小区702的cell ID和频点B添加至禁用名单1后，可启动时长为300s的定时器1。在定时器1未超时的这段时间内，由于第二小区702位于上述禁用名单1中，因此，即使第二小区702满足小区重选条件，第二小区702也无法作为候选小区参与终端设备1的小区重选流程。例如，终端设备1检测到第二小区702的信号后，可忽略(例如丢弃)该信号，使得第二小区702无法作为候选小区参与终端设备1的小区重选流程。
当上述定时器1超时后，终端设备1可将第二小区702的cell ID、频点B等信息从表1所示的禁用名单1中删除。这样，第二小区702又可以重新作为候选小区参与终端设备1的小区重选流程。
在另一些实施例中，当第二小区702的PLMN与第一小区701的PLMN不是 EPLMN，且第二小区702所属的运营商B与终端设备1签约的运营商A有共建关系时，终端设备1还可以根据终端设备1的移动状态、终端设备1的电量、终端设备1的屏幕使用状态或终端设备1的服务小区(即第一小区701)的信号质量等一项或多项条件，确定是否将第二小区702添加至上述禁用名单1中。
示例性的，如图10所示，如果第一小区701的信号质量大于信号质量阈值1，说明第一小区701目前能够为终端设备1提供质量较高的信号服务，则终端设备1可继续驻留在第一小区701，不触发小区重选流程。如果第一小区701的信号质量小于信号质量阈值2(信号质量阈值2小于或等于信号质量阈值1)，说明第一小区701已经无法为终端设备1提供质量较高的信号服务，则终端设备1可将第二小区702添加至上述禁用名单1中，以便终端设备1尽快通过小区重选流程接入信号质量较高的小区中。相应的，如果第一小区701的信号质量在信号质量阈值1和信号质量阈值2之间，则终端设备1可沿用现有技术将第二小区702的频点B添加至上述禁用名单1中。
示例性的，如图11所示，如果终端设备1处于速度较快的移动状态，例如终端设备1的移动速度大于速度阈值，则终端设备1可将第二小区702添加至上述禁用名单1中，以便终端设备1尽快通过小区重选流程接入信号质量较高的小区中，保证终端设备1的移动性能。
如果终端设备1处于速度较慢的移动状态，例如终端设备1的移动速度小于上述速度阈值或接近0时，终端设备1还可以结合第一小区701的信号质量确定是否将第二小区702添加至上述禁用名单1中。例如，仍如图11所示，当终端设备1处于速度较慢的移动状态时，如果第一小区701的信号质量大于上述信号质量阈值1，则终端设备1可继续驻留在第一小区701，不触发小区重选流程；如果第一小区701的信号质量小于上述信号质量阈值2，则终端设备1可将第二小区702添加至上述禁用名单1中；如果第一小区701的信号质量在信号质量阈值1和信号质量阈值2之间，则终端设备1可沿用现有技术将第二小区702的频点B添加至上述禁用名单1中。
示例性的，如图12所示，如果终端设备1的屏幕处于亮屏状态，说明用户很可能正在使用终端设备1，则终端设备1可将第二小区702添加至上述禁用名单1中，以便终端设备1尽快通过小区重选流程接入信号质量较高的小区中，保证终端设备1的移动性能。如果终端设备1的屏幕处于息屏(或黑屏)状态，说明用户当前对终端设备1没有使用需求，则终端设备1可沿用现有技术将第二小区702的频点B添加至上述禁用名单1中，降低小区重选流程的功耗开销。
示例性的，如图13所示，如果终端设备1的电量大于电量阈值，说明终端设备1的电量较为充足，则终端设备1可将第二小区702添加至上述禁用名单1中，以小区这种较小的粒度控制各个小区参与终端设备1的小区重选。
如果终端设备1的电量小于电量阈值，则终端设备1还可以结合终端设备1的屏幕状态确定是否将第二小区702添加至上述禁用名单1中。例如，仍如图13所示，当终端设备1的电量小于电量阈值时，如果终端设备1的屏幕处于亮屏状态，则终端设备1可将第二小区702添加至上述禁用名单1中，以便终端设备1尽快通过小区重选流程接入信号质量较高的小区中；如果终端设备1的屏幕处于息屏(或黑屏)状态，则终端设备1可沿用现有技术将第二小区702的频点B添加至上述禁用名单1中，降 低小区重选流程的功耗开销。
可以理解的是，在第二小区702的PLMN与第一小区701的PLMN不是EPLMN，且第二小区702所属的运营商B与终端设备1签约的运营商A有共建关系的条件下，本领域技术人员还可以根据实际经验或实际应用场景设置其他触发条件将第二小区702添加至上述禁用名单1中，本申请实施例对此不做任何限制。
S605、当第三小区的测量结果满足小区重选条件时，终端设备获取来自第三小区的第二系统消息，第二系统消息中包括第三小区的PLMN，第三小区的频点与第二小区的频点相同。
示例性的，在终端设备1没有接入新的小区前，终端设备1在空闲模式下可持续的按照步骤S601获取最新的配置信息，并按照步骤S602执行小区测量。当终端设备1将第二小区702添加至上述禁用名单1后，最新的配置信息中的测量目标可以包括频点B的第三小区703，第三小区703可以为运营商A和运营商B的共建小区，第三小区703的频点可与第二小区702的频点相同，均为频点B。相应的，如果测量目标包括第三小区703，则最新的配置信息中还可以包括与第三小区703对应的测量门限3。
此时，终端设备1可根据第三小区703的小区标识，查询第三小区703是否在上述表1所示的禁用名单1中。如果第三小区703不在上述禁用名单1中，则终端设备1可按照步骤S602中的相关方法对第三小区703执行小区测量，得到测量结果3；同时，终端设备1也可对第一小区701执行小区测量，得到第一小区701最新的测量结果1。这样，虽然第三小区703的频点与第二小区702的频点相同，均为频点B，但由于终端设备1在步骤S604中是以小区为粒度禁用的第二小区702，并没有禁用频点B，因此，终端设备1可对第三小区703执行小区测量。如果第三小区703满足小区重选条件，则第三小区703可作为候选小区参与终端设备1的小区重选流程。
如果第一小区701最新的测量结果1小于上述测量门限1，且测量结果3大于上述测量门限3时，说明当前终端设备1接收到的第一小区701的信号质量较差，而终端设备1接收到的第三小区703的信号质量较高，如图14所示，终端设备1此时可能靠近或进入第三小区703。此时，终端设备1可确认第三小区703的测量结果满足小区重选条件。进而，终端设备1可将第三小区703作为本次小区重选的候选小区，获取第三小区703的网络设备3发送的系统消息。例如，获取网络设备3广播的SIB消息2。
S606、若第三小区的PLMN与第一小区的PLMN为等效PLMN，则终端设备将第三小区作为目标小区进行驻留。
示例性的，终端设备1获取到网络设备3广播的SIB消息2后，可通过解析SIB消息2得到第三小区703的PLMN。当第三小区703为运营商A和运营商B的共建小区时，第三小区703的PLMN包括第一小区701的PLMN和第二小区702的PLMN这两个PLMN。终端设备1可分别确定两个PLMN是否与第一小区701的PLMN是EPLMN。当第三小区703的一个PLMN与第一小区701的PLMN是EPLMN时，可认为第三小区703的PLMN与第一小区的PLMN为EPLMN。此时，终端设备1可按照正常的小区重选流程，将第三小区703作为目标小区进行接入，使得终端设备1从第一小区701迁移至第三小区703中驻留。
可以看出，虽然上述第三小区703(即共建小区)与第二小区702的频点相同，但由于终端设备1可以以小区为粒度设置小区重选时的禁用名单，因此，当终端设备1禁用第二小区702时，不会影响对相同频点的第三小区703的小区重选流程，使终端设备1在存在共建小区和非共建小区的场景下移动时，能够通过小区重选流程顺利接入与禁用的小区同频的共建小区，从而获得信号质量较好的服务信号，并增强终端设备的移动性能。
上述实施例中是以终端设备1在进行小区重选时，先通过小区重选流程中的小区测量确定满足重选条件的候选小区(例如第二小区702或第三小区703)，再通过获取候选小区的系统消息解析候选小区的PLMN举例说明的。
在一些实施例中，终端设备1也可以在没有发起小区重选流程的时候，通过获取邻区的系统消息解析邻区的PLMN。例如，终端设备1检测到第二小区702的SIB消息后，可通过解析第二小区702的SIB消息获取到第二小区702的PLMN。如果第二小区702的PLMN与服务小区(即第一小区701)的PLMN不是EPLMN，且第二小区702所属的运营商与终端设备1签约的运营商具有共建关系，则当终端设备1后续进行小区重选时，如果检测到第二小区702满足上述重选条件，则终端设备1此时可将第二小区702添加至上述禁用名单中。
在另一些实施例中，终端设备1检测到第二小区702的SIB消息后，如果第二小区702的PLMN与服务小区(即第一小区701)的PLMN不是EPLMN，且第二小区702所属的运营商与终端设备1签约的运营商具有共建关系，则终端设备1可直接将第二小区702添加至上述禁用名单中。这样，后续终端设备1发起小区重选流程后，位于禁用名单中的第二小区702无法参与终端设备1的小区重选流程。但由于与第二小区702同频的第三小区703不在上述禁用名单中，因此，第三小区703可正常参与终端设备1的小区重选流程。如果第三小区703满足上述重选条件，则终端设备1可接入第三小区703。
需要说明的是，上述实施例中的第一小区701、第二小区702以及第三小区703可以为覆盖4G网络的小区(可称为4G小区)，也可以为覆盖5G网络的小区(可称为5G小区)，还可以为使用其他通信技术的小区。终端设备1根据各个小区的频点可以确定对应小区为4G小区、5G小区或使用其他通信技术的小区。
其中，5G小区可以包括独立组网(standalone，SA)的5G小区(也可称为SA小区)和非独立组网(non-standalone，NSA)的5G小区(也可称为NSA小区)。在相同运营商或具有共建关系的运营商建立的5G小区中，NSA小区与SA小区的频点可以相同。
例如，如图15所示，地区2中包括运营商A和运营商B共建的多个5G共建小区。这些5G共建小区中包括NSA小区1401和SA小区1402。此时，NSA小区1401和SA小区1402的频点均为频点C。并且，地区2中还可以包括运营商A建立的第一小区701，第一小区701可以是4G小区或5G小区，第一小区701的频点仍为频点A。
目前，3GPP协议的38.304 5.3.1章节中规定了当NSA小区的MIB(Master Information Block，主信息块)消息中设置了不允许终端设备在同频小区中重选小区，则终端设备需要在小区选择和重选流程中应该禁用当前NSA小区的频点300秒。也就 是说，在这300s内，终端设备无法将与当前NSA小区同频的小区作为目标小区进行小区重选或小区选择(cell selection/reselection)，从而降低终端设备的功耗。
其中，3GPP协议中38.304 5.3.1章节的相关规定如下：
If the field intraFreqReselection in MIB message is set to"not allowed"the UE shall not re-select a cell on the same frequency as the barred cell；The UE shall exclude the barred cell and the cells on the same frequency as a candidate for cell selection/reselection for 300seconds.
在这种场景下，仍如图15所示，签约运营商A的终端设备1在频点A驻留至第一小区701后，如果检测到某一NSA小区1401满足小区重选条件，则终端设备1可进一步解析NSA小区1401的MIB消息。此时，如果MIB消息设置了不允许终端设备在同频小区中重选小区，则终端设备1需要按照上述协议规定禁用NSA小区1401的频点C。与上述实施例中的场景类似的，终端设备1禁用频点C后，与NSA小区1401同频的SA小区1402也无法作为候选小区参与终端设备1的小区选择和小区重选流程，从而影响终端设备1获得的信号质量以及移动性能。
对此，与上述实施例类似的，终端设备1检测到NSA小区1401满足小区重选条件后，如果通过解析NSA小区1401的MIB消息确认不允许终端设备在同频小区中重选小区，则终端设备1可将NSA小区1401添加至预设的禁用名单2中，而不是将NSA小区1401的频点C添加至禁用名单2中。
与上述实施例中的禁用名单1不同的是，上述禁用名单2不仅适用于后续的小区重选流程，还适用于后续的小区选择流程。这样，终端设备1不是以频点为粒度设置小区重选(或小区选择)时的禁用名单，而是以小区为粒度设置小区重选时的禁用名单，使得后续与第二NSA小区1401同频的SA小区仍然可作为候选小区参与终端设备1的小区重选(或小区选择)流程。
示例性的，终端设备仍然可以按照上述实施例中的步骤S601-S606执行对应的方法，此时，第二小区702可以为运营商A和运营商B共建的NSA小区，第三小区703可以为运营商A和运营商B共建的SA小区，第二小区702的频点仍然与第三小区703的频点相同。当然，第二小区702和第三小区703也可以是同频的非共建小区，本申请实施例对此不做任何限制。
与上述实施例中的步骤S601-S606不同的是，终端设备1对第二小区702执行小区测量时，根据第二小区702的频点B可以确定第二小区702为5G小区。此时，如图16所示，通过执行步骤S603，终端设备1可获取到第二小区702的第一系统消息，例如，SIB消息1。进而，终端设备1在执行步骤S604之前还可执行下述步骤S1501-S1502：
S1501、终端设备1确认第二小区702为NSA小区。
示例性的，终端设备1获取到第二小区702的SIB消息1后，可解析SIB消息1中是否携带有与第二小区702的PLMN对应的TAC(tacking area，跟踪区号)。如果没有与第二小区702的PLMN对应的TAC，则终端设备1可确认第二小区702为5G小区中的NSA小区。否则，终端设备1可确认第二小区702为5G小区中的SA小区。
S1502、终端设备1确认第二小区702的MIB消息中配置了不允许同频重选小区 的选项。
示例性的，终端设备1从第二小区702获取的系统消息可以包括SIB消息，还可以包括MIB消息。当终端设备1确认第二小区702为NSA小区后，终端设备1通过解析第二小区702的MIB消息，可确认MIB消息中是否配置了不允许同频重选小区的选项。如果MIB消息中同频重选小区的选项设置为“not allowed”(即不允许)，则终端设备1可确认MIB消息中配置了不允许同频重选小区的选项。
进而，终端设备1可执行上述步骤S604中的相关步骤，即将第二小区702的小区标识以及第二小区的频点添加至预设的禁用名单中。此时的禁用名单可以为禁用名单2，禁用名单2不仅适用于后续的小区重选流程，还适用于后续的小区选择流程。
或者，可设置禁用名单1用于后续的小区重选流程，禁用名单2用于后续的小区选择流程。此时，终端设备1可将第二小区702的小区标识以及第二小区的频点添加至禁用名单1和禁用名单2中。其中，终端设备1将第二小区702添加至禁用名单1(或禁用名单2)的具体方法可参见上述步骤S604的相关描述，故此处不予赘述。
也就是说，当终端设备1确定出第二小区702为5G小区中的NSA小区后，触发终端设备1禁用第二小区702的触发条件，从S604中的第二小区702的PLMN与第一小区701的PLMN不是EPLMN，变为S1502中第二小区702的MIB消息中配置了不允许同频重选小区的选项。
这样，当后续终端设备1检测到与第二小区702的频点相同的SA小区(即第三小区703)满足小区重选条件(或小区选择条件)，则终端设备1仍然可以按照正常的小区重选流程(或小区选择流程)接入第三小区703，使终端设备1在同频的SA小区和NSA小区中移动时，能够通过小区重选流程(或小区选择流程)顺利接入与禁用的NSA小区同频的SA小区，从而获得信号质量较好的服务信号，并增强终端设备的移动性能。
相应的，当后续终端设备1检测到与第二小区702的频点相同的NSA小区满足小区重选条件(或小区选择条件)时，终端设备1可继续通过该NSA小区的MIB消息确定是否将该NSA小区添加至上述禁用名单2中。或者，当后续终端设备1检测到与第二小区702的频点相同的4G小区满足小区重选条件时，终端设备1可跳转至上述实施例的步骤S603，按照步骤S603-S606执行小区重选方法。
