根据本公开的实施例，终端在进行小区重选时，可以根据非激活态组播业务相关信息确定小区的重选优先级，并根据确定的小区重选优先级进行同频小区重选和/或等优先级频点小区重选。例如，终端在需要进行非激活态组播业务的情况下，可以根据接收到的非激活态组播业务相关信息使得支持非激活态组播业务的小区的重选优先级相对于不支持非激活态组播业务的重选优先级相对较高，从而在进行小区重选时终端可以具有更高的可能性重选到支持非激活态组播业务的小区。据此，终端在进行小区重选时可以根据需要进一步考虑小区是否支持非激活态组播业务，从而重选到合适的同频小区和/或等优先级频点小区。

具体实施方式
下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。

图1是根据本公开的实施例示出的一种小区重选方法的示意流程图。本实施例所示的小区重选方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以与网络侧设备通信，所述网络侧设备包括但不限于4G、5G、6G等通信系统中的网络侧设备，例如基站、核心网等。
如图1所示，所述小区重选方法可以包括以下步骤：
在步骤S101中，接收非激活态inactive组播业务MBS(Multicast Broadcast Service，也可以称作多播业务)相关信息；
在步骤S102中，根据所述非激活态组播业务相关信息确定小区重选优先级；
在步骤S103中，根据所述小区重选优先级进行小区重选；
其中，所述根据所述小区重选优先级进行小区重选包括以下至少一项：
根据所述小区重选优先级进行同频小区重选；
根据所述小区重选优先级进行等优先级频点小区重选。
本公开的所有实施例可以应用于同频小区重选也可以应用于等优先级频点小区重选，其中，等优先级频点小区即为频点与终端服务小区频点优先级相同的小区，本公开对此不作限制。
终端在进行小区重选时，可以确定符合小区重选条件的候选小区，例如可以根据S准则确定，终端通过确定候选小区中各小区的小区重选优先级在候选小区中选择合适的小区。应当理解的是，本公开中的小区重选优先级也可以被称作小区重选顺序，在小区重选过程中，小区的重选优先级越高，等同于小区重选顺序越靠前，更大概率被终端重选到。
在本公开的所有实施例中，终端进行小区重选的候选小区可以包括以下至少之一：终端的服务小区、与所述服务小区频点相同的邻小区、与所述服务小区频点优先级相同的邻小区。
当终端进行同频小区重选时，候选小区可以包括终端的服务小区和/或服务小区频点相同的邻小区；当终端进行等优先级频点小区重选时，候选小区可以包括服务小区和/或与服务小区优先级相同的邻小区。
在一个实施例中，所述非激活态组播业务相关信息包括以下至少之一：
非激活态组播业务的配置信息、支持指示信息、与所述非激活态组播业务相关联的小区重选参数。
其中，非激活态组播业务的配置信息用于配置终端执行非激活态组播业务的数据接收，例如非激活态组播业务的配置信息包括终端执行非激活态组播业务数据接收的时域资源、频域资源等；
支持指示信息用于指示支持所述非激活态组播业务的第一小区，和/或不支持非激活态组播业务的第二小区；其中，终端可以根据支持指示信息在候选小区中确定第一小区和/或第二小区，也可以通过其他方式确定第一小区和/或第二小区，例如终端在接收到所述配置信息时，确定接收到所述配置信息时所在的服务小区属于第一小区；
与所述非激活态组播业务相关联的小区重选参数用于确定所述第一小区的小区重选优先级，例如终端基于R准则确定小区重选优先级，所述小区重选参数可以用于对R准则中的参数进行调整。
在相关技术中，终端在进行小区重选时，可以通过小区排序准则(R准则)计算各候选小区的R值，进而基于各候选小区的R值的大小关系对候选小区进行排序，从而可以按照排序结果进行小区重选。具体地，通过R准则计算各候选小区的R值的计算公式如下所示：
R s＝Q meas,s+Q hyst-Qoffset temp；
R n＝Q meas,n-Qoffset-Qoffset temp；
其中，R s表示服务小区的R值，R n表示邻小区的R值，Q mean,s表示服务小区的参考信号接收功率RSRP(Reference Signal Receiving Power)，Q hyst表示服务小区的重选迟滞参数，Qoffset temp表示R准则中在发生多次随机接入失败时新增的偏置参数，Qoffset表示邻小区偏移值，并且其中的Qoffset temp和Qoffset均由网络设备携带在系统消息中广播。
根据上述公式可以看出，终端在进行小区重选时，主要考虑小区的信号质量，根据参考信号接收功率选择信号质量更好的小区驻留。但是在当终端需要进行一些特定业务时，例如需要进行非激活态组播业务时，由于并非所有的小区都支持非激活态组播业务，因此若只考虑小区的信号质量，终端很有可能会重选到某一信号质量较好但不支持非激活态组播业务的小区，从而无法在重选到的小区中进行非激活态组播业务。
而根据本实施例，终端在进行小区重选时，可以根据非激活态组播业务相关信息确定小区重选优先级，并根据确定的小区重选优先级进行小区重选。其中，在不考虑对非激活态组播业务支持与否以外的其他条件时，根据非激活态组播业务相关信息确定小区重选优先级，可以使得在确定的小区重选优先级中第一小区的小区重选优先级比第二小区的小区重选优先级相对较高。
例如，终端在能够支持非激活态组播业务的情况下，或者在能够支持非激活态组播业务且需要进行非激活态组播业务的情况下，可以根据非激活态组播业务相关信息确定小区重选优先级，从而在确定小区重选优先级的过程中，能够考虑非激活态组播业务相关信息，使得在确定出的小区重选优先级中，支持非激活态组播业务的第一小区的小区重选优先级比不支持非激活态组播业务的第二小区的小区重选优先级相对较高，从而在进行小区重选时终端可以具有更高的可能性重选到支持非激活态组播业务的第一小区。据此，有利于确保终端能够在重选到的小区中进行非激活态组播业务。
图2是是根据本公开的实施例示出的另一种小区重选方法的示意图。如图2所示，所述根据所述非激活态组播业务相关信息确定小区重选优先级包括：
在步骤201中，确定支持所述非激活态组播业务的第一小区，和/或不支持所述非激活态组播业务的第二小区；
在步骤202中，根据与所述非激活态组播业务相关联的小区重选参数确定所述 第一小区和/或第二小区的重选优先级，其中，所述小区重选参数用于确定所述第一小区和/或第二小区的小区重选优先级。
在一实施例中，非激活态组播业务相关联的小区重选参数可以由网络设备携带在系统消息(例如，系统信息块SIB2消息和/或SIB3消息)或者专有信令(例如，无线资源控制释放RRCRelease信令)中发送。
在一实施例中，终端可以根据接收到的小区重选参数确定第一小区的第一重选优先级。以R准则为例，在计算支持非激活态组播业务的第一小区的R值时，可以在相关技术的R值计算公式中的原有参数的基础上，引入小区重选参数，增加支持非激活态组播业务的第一小区的R值，从而提高小区重选中的排名。作为一种可能的实施方式，通过R准则计算第一小区的R值的计算公式如下所示：
R s＝Q meas,s+Q hyst-Qoffset temp+Qoffset multicast(式1)；
R n＝Q meas,n-Qoffset-Qoffset temp+Qoffset multicast(式2)；
其中，Qoffset multicast即为与非激活态组播业务相关联的小区重选参数。
在一个实施例中，终端在计算R值可以不再使用Qoffset和Qoffset temp，而是可以直接根据Q meas,s、Q hyst和小区重选参数计算R s，根据Q meas,n和小区重选参数计算R n值。
终端在接收到非激活态组播业务的相关信息后可以确定支持非激活态组播业务的第一小区和/或不支持非激活态组播业务的第二小区，例如，可以根据非激活态组播业务的相关信息中的指示支持指示信息确定第一小区和/或第二小区；也可以确定接收到所述配置信息时所在的服务小区属于第一小区。
进而在确定小区的重选优先级时，可以根据与非激活态组播业务相关联的小区重选参数计算第一小区和/或第二小区的重选优先级，使得第一小区的重选参数高于不支持非激活态组播业务的第二小区，从而令终端可以优先重选到支持非激活态组播业务的小区上，有利于确保终端能够在重选到的小区中进行非激活态组播业务。
在一个实施例中，终端在根据接收到的小区重选参数确定第一小区的第一重选优先级后，可以根据确定的第一小区的第一重选优先级，仅在第一小区中进行小区重选，而不考虑第二小区，避免重选到不支持非激活态组播业务的小区，有利于确保终端能够在重选到的小区中进行非激活态组播业务。
在一个实施例中，终端除了可以根据小区重选参数确定第一小区的第一重选优先级，也可以根据小区重选参数确定第二小区的重选优先级，但是在确定第二小区的重选优先级时，可以将上述式1和式2中的Qoffset multicast视为0，那么相当于是依然按照现有的R准则，通过计算Q meas,s+Q hyst-Qoffset temp确定第二小区的R s值，通过计算Q meas,n-Qoffset-Qoffset temp确定第二小区的R n值，从而仍能使得确定的小区重选优先级中第一小区的小区重选优先级比第二小区的小区重选优先级相对较高。
在一个实施例中，在确定第二小区的第二重选优先级的情况下，终端可以不仅仅只在支持非激活态组播业务的第一小区中进行小区重选，而是可以根据所确定的第一小区的第一重选优先级和第二小区的第二重选优先级，针对所有支持和不支持非激活态组播业务的小区(第一小区和第二小区)进行排序，从而在所有满足小区重选条件的候选小区中进行小区重选。
在一个实施例中，终端还可以在接收到的小区重选参数满足预设条件(例如，小区重选参数为无穷大)的情况下，先在第一小区中进行小区重选，在根据所述第一重选优先级在第一小区中进行小区重选未能成功重选到小区的情况下，再进一步在所有的重选候选小区中进行小区重选。
具体的，当终端确定接收到的小区重选参数为无穷大时，可以确定需要现在第一小区中进行小区重选，在第一小区中进行小区重选未能成功重选到小区的情况下再在所有候选小区中进行小区重选，也即小区重选参数除了可以用于计算R值，还起到了指示作用。进而终端先根据第一重选优先级在第一小区中进行小区重选，第一小区中进行小区重选未能成功重选到小区的情况下，终端再进一步根据在所有的候选小区中进行小区重选。在该情况下，终端在计算各第一小区的R值时将小区重选参数视为0。
图3是是根据本公开的实施例示出的又一种小区重选方法的示意图。如图3所示，确定支持所述非激活态组播业务的第一小区，和/或不支持所述非激活态组播业务的第二小区包括：
在步骤S301中，响应于终端接收到非激活态组播业务的配置信息，确定所述终端接收到所述非激活态组播业务的配置信息的所述小区为支持所述非激活态组播业务的第一小区，其中，所述配置信息用于配置所述终端执行非激活态组播业务接收。
其中，终端接收到所述非激活态组播业务的配置信息的小区可以包括以下至少 一项：
终端处于连接态时配置的支持组播业务的一个或多个小区；具体可以是主小区、辅小区、主辅小区等，本公开对此不作限制。
终端当前接收到非激活态组播业务配置信息时所处的服务小区；也可以包括终端曾经接收到配置信息时所驻留的小区；具体可以是主小区、辅小区、主辅小区等，本公开对此不作限制。
由于网络设备发送的非激活态组播业务的配置信息用于配置终端执行非激活态组播业务的数据接收，因此终端在任一小区接收到该配置信息，即可默认该小区支持非激活态组播业务，无需网络设备另行发送支持指示信息来指示该小区是否支持非激活态组播业务，减少了通信资源的消耗。
图4是是根据本公开的实施例示出的又一种小区重选方法的示意图。如图4所示，确定支持所述非激活态组播业务的第一小区，和/或不支持所述非激活态组播业务的第二小区包括：
在步骤S401中，基于支持指示信息确定支持所述非激活态组播业务的第一小区，和/或不支持所述非激活态组播业务的第二小区。
其中，所述支持指示信息包括以下至少之一：
支持非激活态组播业务的小区的第一列表Cell list1；
不支持非激活态组播业务的小区的第二列表Cell list2；
支持非激活态组播业务的无线接入网络通知区域RNA(Radio Access Network Notification Area)的第三列表RNA list1；
不支持非激活态组播业务的无线接入网络通知区域RNA的第四列表RNA list2。
在一个实施例中，所述根据所述支持指示信息确定所述第一小区，和/或所述第二小区包括：
确定属于所述第一列表或第三列表的小区为第一小区；
确定不属于所述第二列表或第四列表的小区为第一小区；
确定不属于所述第一列表或第三列表的小区为第二小区；
确定属于所述第二列表或第四列表的小区为第二小区。
网络设备通过将指示支持和/或不支持非激活态组播业务的区域列表作为支持指示信息，携带在非激活态组播业务相关信息中发送给终端，使得终端在接收到非激活态组播业务相关信息后可以根据其中所包含的区域列表确定支持非激活态组播业务的小区和/或不支持非激活态组播业务的小区。其中，所述区域列表可以是小区列表,也可以是RNA列表，本公开对此不作限制。
在一个实施例中，终端可以基于支持指示信息中所包含的小区列表确定支持所述非激活态组播业务的第一小区，和/或不支持所述非激活态组播业务的第二小区。例如，终端可以在确定接收到的非激活态组播业务的相关信息中包含支持非激活态组播业务的小区的Cell list1的情况下，确定Cell list1中所包含的候选小区为第一小区，而Cell list1中未包含的候选小区即为第二小区。又例如，终端可以在确定接收到的非激活态组播业务的相关信息中包含不支持非激活态组播业务的小区的Cell list2的情况下，确定Cell list2中所包含的候选小区为第二小区，而Cell list2中未包含的候选小区即为第一小区。
在一个实施例中，终端可以基于支持指示信息中所包含的RNA列表确定支持所述非激活态组播业务的第一小区，和/或不支持所述非激活态组播业务的第二小区。例如，终端可以在确定接收到的非激活态组播业务的相关信息中包含支持非激活态组播业务的无线接入网络通知区域RNA的RAN list1的情况下，确定属于RNA list1中RAN所对应的小区的候选小区为第一小区，而不属于RAN list1中RAN所对应的小区的候选小区为第二小区。又例如，终端可以在确定接收到的相关信息中包含不支持非激活态组播业务的无线接入网络通知区域RNA的RAN list2的情况下，确定属于RNA list2中RAN所对应的小区的候选小区为第二小区，而不属于RNA list2中RNA所对应的小区的候选小区即为第一小区。
当然，上述实施例只是对本公开中支持指示信息的一种示例性描述，实际上本公开中的支持指示信息除了列表的形式以外，还可以以其他的形式表示，本公开对此不作限制。
图5是是根据本公开的实施例示出的又一种小区重选方法的示意图。如图5所示，所述根据所述非激活态组播业务相关信息确定小区重选优先级包括：
在步骤S501中，确定支持所述非激活态组播业务的第一小区的重选优先级高 于不支持所述非激活态组播业务的第二小区的重选优先级。
在一个实施例中，终端可以根据如前所述的方法将非激活态组播业务相关联的小区重选参数引入R准则计算小区的R值，进而通过比较小区的R值确定小区重选优先级。终端也可以由终端根据需要自行确定小区重选优先级；还可以由网络设备确定小区重选优先级，进而将小区重选优先级指示给终端，具体可以参考如下所述的实施例，此处不再赘述。
在一个实施例中，终端在确定第一小区和/或第二小区后，可以根据需要自行将第一小区的重选优先级设置为最高优先级。即终端可以自行确定所有第一小区的重选优先级均高于第二小区的重选优先级，并根据确定的重选优先级进行小区重选，从而使得终端在根据该小区重选优先级进行小区重选时可以优先重选到支持非激活态组播业务的小区。并且针对各第一小区，终端可以根据自身实现自行确定各第一小区之间的重选优先级高低，也可以将各第一小区视为等优先级，本公开对此不作限制。
在一实施例中，网络设备可以向终端下发小区优先级，以使终端根据网络侧下发的小区优先级确定小区重选优先级。例如，网络设备可以将小区优先级携带在非激活组播业务的相关信息中发送，终端在接收到的非激活态组播业务的相关信息后可以根据其中所包含的配置信息和/或支持指示信息确定支持非激活态组播业务的第一小区和/或不支持非激活态组播业务的第二小区后，终端可以直接根据相关信息中所包含的小区优先级确定各小区之间的优先级高低，从而根据确定出的小区重选优先级进行小区重选。
在一个实施例中，网络设备在向终端下发小区优先级后，终端也可以先自主确定支持非激活组播业务的第一小区的优先级均高于第二小区的优先级，而后再根据接收到的网络设备所下发的小区优先级确定各第一小区之间的优先级高低。其中网络设备发送的小区优先级可以包括支持非激活态组播业务的第一小区的小区优先级，或者可以包括不支持非激活态组播业务的第二小区的小区优先级，又或者可以包括第一小区和第二小区的小区优先级，本公开对此不作限制。
在一实施例中，终端在接收到网络设备发送的非激活态组播业务相关信息后，可以先判断非激活态组播业务相关信息中是否包含有优先级信息，在确定非激活态组播业务相关信息中包含优先级信息的情况下，可以根据网络设备所配置的优先级信息确定候选小区的小区重选优先级；若非激活态组播业务相关信息中不包含优先级信息，则终端可以根据需要自行设置第一小区与第二小区的重选优先级的高低，确定候选小 区的小区重选优先级。
图6是是根据本公开的实施例示出的又一种小区重选方法的示意图。如图6所示，所述方法还包括：
在步骤S601中，向网络设备上报能力信息，所述能力信息用于指示所述终端是否支持非激活态组播业务的能力。
终端在进行小区重选前，可以预先向网络设备上报用于指示自身是否支持非激活态组播业务的能力信息，使得网络设备可以根据接收到能力信息确定是否向终端提供非激活态组播业务相关信息。
网络设备在根据终端所上报的能力信息确定终端支持非激活态组播业务时，可以向终端提供非激活态组播业务相关信息，以使终端能够优先重选到支持非激活态组播业务的小区；而在根据终端所上报的能力信息确定终端不支持非激活态态组播业务时，则无需向终端提供非激活态组播业务相关信息，从而可以减少通信资源的消耗，且使得终端可以根据原有的小区重选方法驻留到信号质量最好的小区。
图7是根据本公开的实施例示出的一种非激活态组播业务相关信息发送方法的示意流程图。本实施例所示的非激活态组播业务相关信息发送方法可以由网络侧设备执行，所述网络侧设备可以与终端通信，所述网络侧设备包括但不限于4G基站、5G基站、6G基站等通信系统中的基站，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图7所示，所述非激活态组播业务相关信息发送方法可以包括以下步骤：
在步骤S701中，向终端发送非激活态组播业务相关信息，所述非激活态组播业务相关信息用于指示终端根据所述非激活态组播业务相关信息确定用于进行同频小区重选和/或等优先级频点小区重选的小区重选优先级。
在一实施例中，网络设备通过向终端发送非激活态组播业务相关信息，使得终端可以根据接收到的非激活态组播业务相关信息确定小区重选优先级，并根据所述小区重选优先级进行小区重选。
本公开的所有实施例可以应用于同频小区重选也可以应用于等优先级频点小区重选，本公开对此不作限制。
终端在进行小区重选时，可以确定符合小区重选条件的候选小区，例如可以根 据S准则确定，终端通过确定候选小区中各小区的小区重选优先级在候选小区中选择合适的小区。应当理解的是，本公开中的小区重选优先级也可以被称作小区重选顺序，在小区重选过程中，小区的重选优先级越高，等同于小区重选顺序越靠前，越容易被终端重选到。
在本公开的所有实施例中，终端进行小区重选的候选小区可以包括以下至少之一：终端的服务小区、与所述服务小区频点相同的邻小区、与所述服务小区频点优先级相同的邻小区。
当终端进行同频小区重选时，候选小区可以包括终端的服务小区和/或服务小区频点相同的邻小区；当终端进行等优先级频点小区重选时，候选小区可以包括服务小区和/或与服务小区优先级相同的邻小区。
在一个实施例中，所述非激活态组播业务相关信息包括以下至少之一：
非激活态组播业务的配置信息、支持指示信息、与所述非激活态组播业务相关联的小区重选参数。
其中，非激活态组播业务的配置信息用于配置终端执行非激活态组播业务的数据接收，例如非激活态组播业务的配置信息包括终端执行非激活态组播业务数据接收的时域资源、频域资源等；
支持指示信息用于指示支持所述非激活态组播业务的第一小区，和/或不支持非激活态组播业务的第二小区；其中，终端可以根据支持指示信息在候选小区中确定第一小区和/或第二小区，也可以通过其他方式确定第一小区和/或第二小区，例如终端在接收到所述配置信息时，可以记录接收到所述配置信息时所在的服务小区，并确定接收到所述配置信息时所在的服务小区属于第一小区；
与所述非激活态组播业务相关联的小区重选参数用于确定所述第一小区的小区重选优先级，例如终端基于R准则确定小区重选优先级，所述小区重选参数可以用于对R准则中的参数进行调整。
在相关技术中，终端在进行小区重选时，可以通过小区排序准则(R准则)计算各候选小区的R值，进而基于各候选小区的R值的大小关系对候选小区进行排序，从而可以按照排序结果进行小区重选。具体地，通过R准则计算各候选小区的R值的计算公式如下所示：
R s＝Q meas,s+Q hyst-Qoffset temp；
R n＝Q meas,n-Qoffset-Qoffset temp；
其中，R s表示服务小区的R值，R n表示邻小区的R值，Q mean,s表示服务小区的参考信号接收功率RSRP(Reference Signal Receiving Power)，Q hyst表示服务小区的重选迟滞参数，Qoffset temp表示R准则中在发生多次随机接入失败时新增的偏置参数，Qoffset表示邻小区偏移值，并且其中的Qoffset temp和Qoffset均由网络设备携带在系统消息中广播。
根据上述公式可以看出，终端在进行小区重选时，主要考虑小区的信号质量，根据参考信号接收功率选择信号质量更好的小区驻留。但是在当终端需要进行一些特定业务时，例如需要进行非激活态组播业务时，由于并非所有的小区都支持非激活态组播业务，因此若只考虑小区的信号质量，终端很有可能会重选到某一信号质量较好但不支持非激活态组播业务的小区，从而无法在重选到的小区中进行非激活态组播业务。
而根据本实施例，终端在进行小区重选时，可以根据非激活态组播业务相关信息确定小区重选优先级，并根据确定的小区重选优先级进行小区重选。其中，在不考虑支持非激活态组播业务的第一小区比不支持非激活态组播业务的第二小区的其他条件(除了对非激活态组播业务支持与否以外的条件)时，根据非激活态组播业务相关信息确定小区重选优先级，可以使得在确定的小区重选优先级中第一小区的小区重选优先级比第二小区的小区重选优先级相对较高。
例如，终端在能够支持非激活态组播业务的情况下，或者在能够支持非激活态组播业务且需要进行非激活态组播业务的情况下，可以根据非激活态组播业务相关信息确定小区重选优先级，从而在确定小区重选优先级的过程中，能够考虑非激活态组播业务相关信息，使得在确定出的小区重选优先级中，支持非激活态组播业务的第一小区的小区重选优先级比不支持非激活态组播业务的第二小区的小区重选优先级相对较高，从而在进行小区重选时终端可以具有更高的可能性重选到支持非激活态组播业务的第一小区。据此，有利于确保终端能够在重选到的小区中进行非激活态组播业务。
在一实施例中，网络设备可以将非激活态组播业务相关联的小区重选参数携带在系统消息(例如，系统信息块SIB2消息和/或SIB3消息)或者专有信令(例如，无线资源控制释放RRCRelease信令)中发送。
在一实施例中，网络设备将将非激活态组播业务相关联的小区重选参数发送至 终端后，终端可以根据接收到的小区重选参数确定第一小区的第一重选优先级。以R准则为例，在计算支持非激活态组播业务的第一小区的R值时，可以在相关技术的R值计算公式中的原有参数的基础上，引入小区重选参数，增加支持非激活态组播业务的第一小区的R值，从而提高小区重选中的排名。作为一种可能的实施方式，通过R准则计算第一小区的R值的计算公式如下所示：
Rs＝Qmeas,s+Qhyst-Qoffsettemp+Qoffsetmulticast(式1)；
Rn＝Qmeas,n-Qoffset-Qoffsettemp+Qoffsetmulticast(式2)；
其中，Qoffsetmulticast即为与非激活态组播业务相关联的小区重选参数。
在一个实施例中，终端在计算R值可以不再使用Qoffset和Qoffsettemp，而是可以直接根据Qmeas,s、Qhyst和小区重选参数计算Rs，根据Qmeas,n和小区重选参数计算Rn值。
终端在接收到非激活态组播业务的相关信息后可以确定支持非激活态组播业务的第一小区和/或不支持非激活态组播业务的第二小区，例如，可以根据非激活态组播业务的相关信息中的指示支持指示信息确定第一小区和/或第二小区；也可以确定接收到所述配置信息时所在的服务小区属于第一小区。
进而在确定小区的重选优先级时，可以根据与非激活态组播业务相关联的小区重选参数计算第一小区和/或第二小区的重选优先级，使得第一小区的重选参数高于不支持非激活态组播业务的第二小区，从而令终端可以优先重选到支持非激活态组播业务的小区上，有利于确保终端能够在重选到的小区中进行非激活态组播业务。
在一个实施例中，终端除了可以根据小区重选参数确定第一小区的第一重选优先级，也可以根据小区重选参数确定第二小区的重选优先级，但是在确定第二小区的重选优先级时，可以将上述式1和式2中的Qoffsetmulticast视为0，那么相当于是依然按照现有的R准则，通过计算Qmeas,s+Qhyst-Qoffsettemp确定第二小区的Rs值，通过计算Qmeas,n-Qoffset-Qoffsettemp确定第二小区的Rn值，从而仍能使得确定的小区重选优先级中第一小区的小区重选优先级比第二小区的小区重选优先级相对较高。
在一个实施例中，在确定第二小区的第二重选优先级的情况下，终端可以不仅仅只在支持非激活态组播业务的第一小区中进行小区重选，而是可以根据所确定的第一小区的第一重选优先级和第二小区的第二重选优先级，针对所有支持和不支持非激活态组播业务的小区(第一小区和第二小区)进行排序，从而在所有满足小区重选条 件的候选小区中进行小区重选。
在一个实施例中，终端还可以在接收到的小区重选参数满足预设条件(例如，小区重选参数为无穷大)的情况下，先在第一小区中进行小区重选，在根据所述第一重选优先级在第一小区中进行小区重选未能成功重选到小区的情况下，再进一步在所有的重选候选小区中进行小区重选。
具体的，当终端确定接收到的小区重选参数为无穷大时，可以确定需要现在第一小区中进行小区重选，在第一小区中进行小区重选未能成功重选到小区的情况下再在所有候选小区中进行小区重选，也即小区重选参数除了可以用于计算R值，还起到了指示作用。进而终端先根据第一重选优先级在第一小区中进行小区重选，第一小区中进行小区重选未能成功重选到小区的情况下，终端再进一步根据在所有的候选小区中进行小区重选。在该情况下，终端在计算各第一小区的R值时将小区重选参数视为0。
在一实施例中，所述支持指示信息包括以下至少之一：
支持非激活态组播业务的小区的第一列表；
不支持非激活态组播业务的小区的第二列表
支持非激活态组播业务的无线接入网络通知区域RNA的第三列表；
不支持非激活态组播业务的无线接入网络通知区域RNA的第四列表。
网络设备通过将指示支持和/或不支持非激活态组播业务的区域列表作为支持指示信息，携带在非激活态组播业务相关信息中发送给终端，使得终端在接收到非激活态组播业务相关信息后可以根据其中所包含的区域列表确定支持非激活态组播业务的小区和/或不支持非激活态组播业务的小区。其中，所述区域列表可以是小区列表,也可以是RNA列表，本公开对此不作限制。
在一个实施例中，终端可以基于支持指示信息中所包含的小区列表确定支持所述非激活态组播业务的第一小区，和/或不支持所述非激活态组播业务的第二小区。例如，终端可以在确定接收到的非激活态组播业务的相关信息中包含支持非激活态组播业务的小区的第一列表Cell list1的情况下，确定该第一列表Cell list1中所包含的候选小区为第一小区，而该第一列表Cell list1中未包含的候选小区即为第二小区。又例如，终端可以在确定接收到的非激活态组播业务的相关信息中包含不支持非激活态组播业务的小区的第二列表Cell list2的情况下，确定该第二列表Cell list2中所包含的候选小 区为第二小区，而该第二列表Cell list2中未包含的候选小区即为第一小区。
在一个实施例中，终端可以基于支持指示信息中所包含的RNA列表确定支持所述非激活态组播业务的第一小区，和/或不支持所述非激活态组播业务的第二小区。例如，终端可以在确定接收到的非激活态组播业务的相关信息中包含支持非激活态组播业务的无线接入网络通知区域RNA的第三列表RAN list1的情况下，确定属于该第三列表RNA list1中RAN所对应的小区的候选小区为第一小区，而不属于该第三列表RAN list1中RAN所对应的小区的候选小区为第二小区。又例如，终端可以在确定接收到的相关信息中包含不支持非激活态组播业务的无线接入网络通知区域RNA的第四列表RAN list2的情况下，确定属于该第四列表RNA list2中RAN所对应的小区的候选小区为第二小区，而不属于该第四列表RNA list2中RNA所对应的小区的候选小区即为第一小区。
在一个实施例中，网络设备向终端发送的非激活态组播业务相关信息中包括用于配置所述终端执行非激活态组播业务接收的配置信息，终端接收到所述非激活态组播业务的配置信息的小区可以包括以下至少一项：
终端处于连接态时配置的支持组播业务的一个或多个小区；具体可以是主小区、辅小区、主辅小区等，本公开对此不作限制。
终端当前接收到非激活态组播业务配置信息时所处的服务小区；也可以包括终端曾经接收到配置信息时所驻留的小区；具体可以是主小区、辅小区、主辅小区等，本公开对此不作限制。
由于网络设备发送的非激活态组播业务的配置信息用于配置终端执行非激活态组播业务的数据接收，因此终端在任一小区接收到该配置信息，即可默认该小区支持非激活态组播业务，无需网络设备另行发送支持指示信息来指示该小区是否支持非激活态组播业务，减少了通信资源的消耗。
在一个实施例中，网络设备可以向终端下发小区优先级，以使终端根据网络侧下发的小区优先级确定小区重选优先级。例如，网络设备可以将小区优先级携带在非激活组播业务的相关信息中发送，终端在接收到的非激活态组播业务的相关信息后可以根据其中所包含的配置信息和/或支持指示信息确定支持非激活态组播业务的第一小区和/或不支持非激活态组播业务的第二小区后，终端可以直接根据相关信息中所包含的小区优先级确定各小区之间的优先级高低，从而确定小区的重选优先级。
在一个实施例中，网络设备在向终端下发小区优先级后，终端也可以先自主确定支持非激活组播业务的第一小区的优先级均高于第二小区的优先级，而后再根据接收到的网络设备所下发的小区优先级确定各第一小区之间的优先级高低，本公开对此不作限制。其中终端发送的小区优先级可以包括支持非激活态组播业务的第一小区的小区优先级，或者可以包括不支持非激活态组播业务的第二小区的小区优先级，又或者可以包括第一小区和第二小区的小区优先级，本公开对此不作限制。
图8是根据本公开的实施例示出的又一种小区重选方法的示意图。如图12所示，所述方法还包括：
在步骤801中，接收终端上报的能力信息，所述能力信息用于指示所述终端是否支持非激活态组播业务的能力。
网络设备在向终端发送非激活态组播业务相关信息前，可以接收终端上报用于指示自身是否支持非激活态组播业务的能力信息，从而可以根据终端所上报的能力信息，在确定终端支持非激活态组播业务的情况下向终端提供非激活态组播业务相关信息，以使终端能够优先重选到支持非激活态组播业务的小区；而在确定终端不支持非激活态态组播业务的情况下，则无需向终端提供非激活态组播业务相关信息，减少占用数据传输资源，使终端可以根据常规的小区重选方法驻留到信号质量最好的小区。
