本申请实施例提供了一种小区驻留方法，应用于终端。终端的具体类型，本申请不做限定，其可以为任何用户设备，例如可以为智能手机、个人计算机、笔记本电脑、平板电脑和便携式可穿戴设备等。
需要说明的是，在本申请的实施例中，终端可以从第一小区和第二小区中选取小区驻留，第一小区和第二小区为不同网络制式的小区，第一小区的重选优先级高于第二小区的重选优先级，具体的第一小区和第二小区本申请实施例不作限定。
具体的，在本申请的实施例中，第一小区为SA制式的小区，简称SA小区，第二小区为LTE制式的小区，简称LTE小区。当然，第一小区和第二小区还可以为其它不同类型网络的小区，本申请实施例不作限定。
图1为本申请实施例提供的一种示例性的小区驻留方法的应用场景图。如图1所示，终端10与网络设备之间建立通信连接，可选地，终端10可 与网络设备通过第四代、第五代等通信技术建立通信连接，其通信连接方式在本申请实施例中不作限定。该网络设备可以包括接入网设备20，以及与接入网设备20进行通信的一个或多个核心网设备30。
在一些实施例中，终端10可以称之为用户设备(user equipment，UE)。该终端可以为个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)等设备，该终端也可以为手机、移动台(mobile station，MS)、终端(mobile terminal)和笔记本电脑等，该终端10可以经无线接入网(radio access network，RAN)与一个或多个核心网进行通信。例如，终端10可以是移动电话(或称为“蜂窝”电话)或具有终端的计算机等，例如，终端10还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。终端10还可以为有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来演进的网络中的终端等，本申请实施不作限定。
接入网设备20可以是长期演进(long-term evolution，LTE)系统、新空口(移动通信系统)(new radio，NR)系统或者授权辅助接入长期演进(authorized auxiliary access long-term evolution，LAA-LTE)系统中的演进型基站(evolutional node B，简称可以为eNB或e-NodeB)宏基站、微基站(也称为“小基站”)、微微基站、接入站点(access point，AP)、传输站点(transmission point，TP)或新一代基站(new generation Node B，gNodeB)等。
在本申请实施例中，对于5G的SA网络架构，接入网设备20可为NR系统的gNodeB，其进行通信的核心网设备30可为下一代核心(Next Generation Core，NGC)设备。在接入网设备为LTE系统的基站时，则其进行通信的核心网设备30可为演进分组核心网(Evolved Packet Core，EPC)。
在相关的技术中，5G的SA网络作为新的网络制式，网络设备会配置高优先级给采用SA网络架构的SA制式的小区，终端会优先选择SA小区驻留。但是终端在通过SA小区进行通信时的功耗远比通过LTE小区进行通信时要大。
图2为本申请实施例提供的一种小区驻留方法的流程示意图一。如图1所示，在本申请的实施例中，小区驻留方法主要包括以下步骤：
S201、当终端在第一小区驻留第一预设时长后，若终端满足第一预设条件，则降低第一小区的重选优先级，以使终端驻留到第二小区。
在本申请的实施例中，当终端在第一小区驻留第一预设时长后，若终端满足第一预设条件，则降低第一小区的重选优先级，以使终端驻留到第二小区。
需要说明的是，在本申请的实施例中，第一预设时长为根据实际需求和应用场景预先设定的时长。具体的第一预设时长本申请实施例不作限定。
小区，也可叫蜂窝小区，是指在蜂窝移动通信系统中，其中的一个基站或基站的一部分(如扇形天线等)所覆盖的区域，在这个被覆盖的区域内的终端可以通过无线信道与基站进行通信。可选地，在本申请实施例中的第一小区可以是SA小区，指的是采用SA网络架构的5G基站(即与5G核心网进行通信的5G基站)所覆盖的区域。
在一些实施例中，在终端开机后，可选择PLMN(Public Land Mobile Network，公共陆地移动网)进行注册，并在注册成功后，从注册的PLMN中选择一个小区驻留，以便终端通过驻留的小区接受业务服务。终端可选择第一小区，即SA小区，或者，第二小区，即LTE小区驻留。可选地，终端在选择小区驻留时，可先进行小区搜索，终端可与检测到的各个小区取得时间和频率同步，从而得到各个小区的物理标识，并可根据该物理标识获取各个小区的参数(例如信号质量等)选择合适的小区驻留。
需要说明的是，在本申请的实施例中，在终端正常驻留在一个小区后，可重新选择一个小区进行驻留。不同类型的小区可分别对应不同的重选优先级，其中，小区的类型可包括但不限于LTE小区、SA小区、NR小区等。在相关技术中，由于5G的SA网络属于较新的网络制式，因此SA小区通常被配置为高优先级，若搜索到的可选择小区中SA小区，SA小区的重选优先级会高于LTE小区的重选优先级，即SA小区为第一小区，LTE小区为第二小区，终端在进行小区重选时，容易重选到第一小区并进行驻留。
具体的，在本申请的实施例中，第一预设条件包括以下其中一项或多项：使用场景属于预设白名单场景、亮屏、空闲模式。
需要说明的是，在本申请的实施例中，终端处于空闲模式可指的是终端没有与无线网络建立RRC连接的状态，终端处于空闲模式时可进行小区搜索、小区选择及小区重选等操作。终端在开机后进行小区搜索，可将检测到的各个小区的物理标识及小区信息记录在小区列表中。在终端处于空闲模式并进行小区重选时，可从小区列表中获取搜索到的各个小区的物理标识及小区信息，可根据该小区信息确定各个小区的小区类型。
需要说明的是，在本申请的实施例中，可监测终端的使用场景，并在终端的使用场景属于预设白名单场景时，降低第一小区的重选优先级。使用场景可用于描述终端的运行情况，使用场景可包括但不限于电量状态、需求的业务类型、运行的应用类型、流量使用状态、屏幕使用状态等。其中，电量状态可包括剩余电量；需求的业务类型可指的是终端所需要的业务服务的类型，例如语音业务、视频业务、数据传输业务等；运行的应用类型可包括但不限于社交应用、即时通讯应用、游戏应用、浏览器应用等；流量使用状态可包括预置时间段内的已使用流量及剩余使用流量等；屏幕使用状态可包括熄屏状态、亮屏状态等。
预设白名单场景可根据实际需求进行设定，可以是终端对于数据业务服务的需求较低的场景，也可以是终端当前不具备驻留在第一小区的场景。 在检测到终端的使用场景属于预设白名单场景时，可说明终端不需要驻留在第一小区或不适合驻留在第一小区。在一些实施例中，终端的使用场景属于预设白名单场景可包括以下几种情况中的一种或多种：
(1)终端的剩余电量低于电量阈值。电量阈值可根据实际需求进行设定，例如20％、30％等，可实时监测终端的剩余电量，在剩余电量低于电量阈值时，可说明终端当前可使用的电量较少，则可控制终端进行低功耗模式，而由于驻留在第一小区会导致终端的功耗较高，则可降低第一小区的重选优先级。
(2)终端需求的业务类型属于配置类型。可选地，该配置类型可指的是第二小区对应的网络支持的业务类型，例如语音业务、普通的数据传输业务，终端驻留在第二小区也能够接受该业务类型对应的服务，则可优先选择驻留在第二小区。
(3)终端的剩余使用流量低于流量阈值。流量阈值可根据实际需求进行设定，例如，2GB(千兆字节)、2.5GB等。终端可从当前接入的网络运营商对应的服务器中获取终端的流程使用数据，该流程使用数据可包括预置时间段内(例如1个月内等)可使用的总流量及已使用流量，再根据该总流量及已使用流量得到剩余使用流量，该剩余使用流量可为总流量与已使用流量的差值。可选地，终端也可将预置时间段内可使用的总流量写入流量监控文件中，并实时对流量使用情况进行监控，统计固定时长(例如12小时、24小时等)的流量使用情况，并将该固定时长的流量使用情况写入流量监控文件。在需要确定剩余使用流量时，可根据流量监控文件中记录的总流量及流量使用情况计算得到剩余使用流量。在剩余使用流量低于流量阈值时，可说明终端当前可使用的流量较少，而由于驻留在第一小区会使得流量快速消耗，则可降低第一小区对应的重选优先级。
(4)终端当前运行的应用类型属于目标类型。该目标类型可以是对网络需求较小的应用类型，第二小区提供的数据业务服务能够满足该目标类型的应用的运行需求。可选地，目标类型可以是社交应用、浏览器应用、阅读应用等对网络需求较小的应用类型，但不限于此。在当前运行的应用类型属于目标类型时，终端驻留在第二小区不会影响应用的正常运行，则可优先选择驻留在第二小区。
需要说明的是，在本申请的实施例中，预设白名单场景可以根据实际需求预先设定，本申请实施例不作限定。
具体的，在本申请的实施例中，当终端在第一小区驻留第一预设时长后，若终端处于空闲模式且使用场景属于预设白名单场景，终端则降低第一小区的重选优先级，从而实现终端从第一小区重选到第二小区，驻留到第二小区。
示例性的，在本申请的实施例中，第一预设时长为15分钟，第一小区为SA小区，第二小区为LTE小区，终端在驻留到SA小区时的网速比驻留 到LTE小区的网速快，当终端在SA小区驻留15分钟后，若终端使用场景属于预设白名单场景：当前网速大于预设网速的场景，即当前网速实际上超过实际需求网速，并且处于空闲模式，终端可以降低SA小区的重选优先级，从而进行小区重选，从SA小区切换到LTE小区上驻留，降低终端的功耗。
需要说明的是，在本申请的实施例中，当终端在第一小区驻留第一预设时长后，若终端满足第一预设条件，可将第一小区的重选优先级从第一重选优先级降低至第二重选优先级，可以是将第一小区对应的优先级参数配置为第二重选优先级。其中，第一重选优先级可高于第二小区对应的第三重选优先级，而该第二重选优先级可低于第二小区对应的第三重选优先级，例如，第二小区对应的重选优先级为6，则第二重选优先级可为4、5等。
在一些实施例中，小区的重选优先级可包括绝对优先级及专用优先级，其中，绝对优先级可由网络设置通过参数CellReselPriority设置，并通过系统消息在小区广播中下发给终端。专用优先级则是在终端释放无线资源控制(Radio Resource Control，RRC)连接时，网络设备通过系统内部专用优先级算法直接生成，并通过RRC Connection Release消息下发给终端。可将第一小区对应的专用优先级参数配置为上述的目标优先级，也可设置区别于绝对优先级及专用优先级的优先级参数，并将该优先级参数配置为上述的目标优先级。
可以理解的是，在本申请的实施例中，终端可选择第一小区或第二小区驻留，在终端进行小区重选时，若终端搜索到的小区同时包括第一小区及第二小区，该第一小区及第二小区为不同网络制式的小区，由于第一小区降低后的重选优先级为第二重选优先级，低于第二小区对应的第三重选优先级，因此，终端可驻留在重选优先级较高的第二小区，而不会选择第一小区进行驻留。
在一些实施例中，在终端进行小区重选时，可优先使用上述配置的优先级参数，根据该配置的优先级参数选择驻留的小区。在终端进行小区重选时，可先判断第一小区的优先级参数是否进行了配置，若进行了配置，则可丢弃网络设备下发的优先级信息(包括绝对优先级及专用优先级)，并基于配置的优先级参数选择驻留的小区。进一步地，终端当前驻留在第一小区，由于配置的优先级参数为第二重选优先级，小于第二小区对应的重选优先级，则可使终端选择重选优先级更高的第二小区进行驻留。
在终端进行小区重选时，若第一小区的优先级参数未被配置，则可基于网络设备下发的优先级信息选择驻留的小区，可选择优先级最高的小区进行驻留。
需要说明的是，当终端进行小区重选时，若搜索到的小区仅包括第一小区，则可不考虑配置的优先级参数及网络设备下发的优先级信息等，因 为对于各个第一小区来说，其对应的重选优先级可相同。在此情况下，可直接根据当前驻留的第一小区与相邻小区的信号质量选择目标小区驻留，其中，该相邻小区为与第一小区为同一网络制式的小区。
可选地，可测量当前驻留的第一小区的信号质量，该当前驻留的第一小区的信号质量可为第一小区的RSRP(Reference Signal Receiving Power，参考信号接收功率)值与重选迟滞值(Cell Reselection Hysteresis，CRH)之和，该重选迟滞值可由网络设备进行配置。可测量各个相邻小区的信号质量，相邻小区的信号质量可为相邻小区的RSRP值与配置的邻区重选偏置值(Cell Reselect Offset，CRO)之差。若存在相邻小区的信号质量高于当前驻留的第一小区，则可直接选择信号质量最高的相邻小区作为目标小区进行驻留。可选地，若当前驻留的第一小区的信号质量大于质量阈值，也可直接继续驻留在该第一小区，而不对相邻小区进行测量。
当终端进行小区重选时，若搜索到的小区仅包括第二小区，则可不考虑配置的优先级参数及网络设备下发的优先级信息等，直接根据第二小区与相邻小区的信号质量选择目标小区驻留，其中，该相邻小区为与第二小区为同一网络制式的小区。选择第二小区驻留的方式可与选择第一小区驻留的方式相同，在此不再赘述。
可以理解的是，在本申请的实施例中，当终端在第一小区驻留第一预设时长后，在满足第一预设条件的情况下才降低第一小区的重选优先级，实际上就是根据终端实际的应用场景和使用状态进行小区驻留的控制，抑制了终端在不恰当的时机进行小区重选，切换驻留的小区，降低了终端的功耗。
需要说明的是，在本申请的实施例中，终端在驻留到第一小区后，为了使终端在第一小区驻留第一预设时长，终端可以执行以下步骤：在第一预设时长内，禁止关闭第一小区的背景搜索，以及禁止降低第一小区的重选优先级。
示例性的，在本申请的实施例中，第一预设时长为15分钟，第一小区为SA小区，终端可以在驻留到SA小区后，15分钟内禁止降低SA小区的重选优先级，以及禁止关闭SA小区的背景搜索，从而在15分钟内维持驻留到SA小区。
可以理解的是，在本申请的实施例中，终端可以在处于亮屏的前提下，实际上通常就处于正在使用终端的场景下，驻留到第一小区后，在一定时长内禁止降低第一小区的重选优先级，以及禁止关闭第一小区的背景搜索，从而可以使终端在该时长内继续搜索到第一小区，并且，由于第一小区的重选优先级未被降低，第一小区的重选优先级高于第二小区的重选优先级，因此，终端可以维持驻留到第一小区上，避免频繁切换驻留的小区，降低终端功耗。
需要说明的是，在本申请的实施例中，当终端在第一小区驻留第一预 设时长后，若终端不满足第一预设条件，可以继续禁止降低第一小区的重选优先级，以及禁止关闭第一小区的背景搜索，以使终端继续驻留到第一小区。
需要说明的是，在本申请的实施例中，第一预设条件可以包括使用场景属于预设白名单场景，而预设白名单场景具体可以是与预设黑名单场景不同的场景，这样，终端不满足第一预设条件，具体可以是使用场景处于预设黑名单场景。黑名单场景可以包括以下其中一项或多项：开启无线网络热点、预设应用至前台运行、第二小区对应的网络传输质量差、时延大、与无线接入点连接、开机、飞行模式、插卡、数据卡切换后的5min、电话在第一小区对应的网络启动、深度睡眠下且未开数据网络等。
可以理解的是，在本申请的实施例中，预设黑名单场景为用户较为敏感的场景，在终端的使用场景属于预设黑名单场景的情况下，用户通常是不希望进行驻留小区切换的，因此，终端在经过第一预设时长后，若使用场景为预设黑名单场景下，将继续禁止降低第一小区的重选优先级，以及禁止关闭第一小区的背景搜索，这样，可以促使终端维持继续驻留到第一小区上。上述预设黑名单场景仅为提供的一些可选的示例性场景，具体的预设黑名单场景可以根据实际需求设定，本申请实施例不作限定。
S202、当终端在第二小区驻留第二预设时长后，若终端满足第二预设条件，则恢复第一小区的重选优先级。
在本申请的实施例中，当终端在第二小区驻留第二预设时长后，若终端满足第二预设条件，则恢复第一小区的重选优先级。
具体的，在本申请的实施例中，终端可以通过执行以下步骤确定第二预设时长：获取目标时刻到当前时刻之间，从第一小区重选到第二小区的重选次数；目标时刻，为终端在当前时刻之前，最后一次从灭屏切换到亮屏的时刻，或者，最后一次从飞行模式切换到正常模式的时刻；基于次数和预设单位时长，确定第二预设时长。
需要说明的是，在本申请的实施例中，终端中设置了预设单位时长，预设单位时长具体可以根据实际需求和应用场景预先设定。示例性的，预设单位时长可以为2分钟。具体的预设单位时长本申请实施例不作限定。
需要说明的是，在本申请的实施例中，第二预设时长可以是次数和预设单位时长的乘积，当然，也可以是基于次数和预设单位时长采用其它计算方式确定第二预设时长，本申请实施例不作限定。
需要说明的是，在本申请的实施例中，上述终端确定第二预设时长的方式仅为一种示例性的方式，当然，第二预设时长还可以根据实际需求设定，确定第二预设时长的方式本申请实施例不作限定。
需要说明的是，在本申请的实施例中，第二预设条件可以为终端驻留的第二小区不满足当前的业务需求特征对应的通信条件，该通信条件可包括第二小区提供的业务服务、信号质量等。当然，具体的第二预设条件还 可以根据实际需求设定，例如，第二预设条件还可以为终端处于空闲模式，本申请实施例不作限定。
需要说明的是，在本申请的实施例中，终端选择驻留在第二小区后，可与相应制式的网络建立连接，并进行数据传输。终端可获取当前的业务需求，并获取该业务需求的业务需求特征，该业务需求特征可用于描述终端当前所需的业务服务。业务需求特征可包括业务类型、数据传输速率要求等，其中，业务类型可包括语音业务、视频业务、数据传输业务，数据传输速率要求可包括高速率要求、中速率要求及低速率要求等。终端基于业务需求特征即可确定是否满足第二预设条件。
可以理解的是，在本申请的实施例中，终端的应用程序在运行时，可获取该应用程序中发起业务需求的业务模块，并根据该应用程序及业务模块确定当前的业务需求特征。不同应用程序对数据传输速率要求可不同，例如，浏览器应用等对数据传输速率的要求低，而游戏应用等即时交互类型应用对数据传输速率的要求高。且进一步地，由于发起业务需求的业务模块不同，需求的业务服务及数据传输速率要求也不同。例如，即时通信应用在运行时，若发起业务需求的业务模块为语音业务模块，则需求的业务类型可为语音业务，数据传输速率要求可为中速率要求，若发起业务需求的业务模块为视频模块，则需求的业务类型可为视频业务，数据传输速率要求可为高速率要求。又例如，游戏应用等即时交互类型应用在运行时，若发起业务需求的业务模块为游戏数据传输模块，则需求的业务类型可为数据传输业务，数据传输速率要求可为高速率要求等。
可以理解的是，在本申请的实施例中，第一小区具体为SA小区，第二小区具体为LTE小区，若终端驻留的LTE小区能够提供终端当前所需的业务服务，且信号质量满足需要进行的业务对数据传输速率的要求，则可确定终端驻留的LTE小区满足与业务需求特征对应的通信条件，可直接通过LTE小区接入的网络进行数据传输。若终端驻留的LTE小区不能提供终端当前所需的业务服务，或信号质量不满足进行的业务对数据传输速率的要求，则可确定终端驻留的LTE小区不满足与业务需求特征对应的通信条件，可将恢复SA小区的重选优先级，以使终端可选择SA小区进行驻留。
在一些实施例中，将第一小区对应的重选优先级从第二重选优先级恢复至第一重选优先级可包括：取消对第一小区对应的优先级参数的配置，即可删除之前配置的第一小区对应的优先级参数。在取消对第一小区的优先级参数的配置后，终端在进行小区重选时，可根据网络设备下发的优先级信息选择小区驻留，由于网络设备下发的优先级信息通常为第一小区的重选优先级高于第二小区的重选优先级，则终端可选择该第一小区进行驻留。
需要说明的是，在本申请的实施例中，在将第一小区对应的重选优先级从第二重选优先级恢复至第一重选优先级后，当终端处于空闲态并进行 小区重选时，由于第一重选优先级高于第二小区的第三重选优先级，则可选择第一小区进行驻留。终端驻留在第一小区后，可通过该第一小区进行RRC连接，并通过相应网络进行数据传输。能够保证终端上数据业务的正常进行，贴合用户的实际需求。
在一些实施例中，当终端在第二小区驻留第二预设时长后，若终端满足第二预设条件，则恢复第一小区的重选优先级，即可将第一小区对应的重选优先级从第二重选优先级恢复至第一重选优先级可包括：若距离配置时刻的时长超出定时时长，则将第一小区对应的重选优先级从第二重选优先级恢复至第一重选优先级。
终端在降低第一小区对应的重选优先级时，可将第一小区对应的优先级参数配置为第二重选优先级，并记录配置时刻，该配置时刻即为配置第一小区对应的优先级参数为第二重选优先级的时刻。可设定配置的优先级参数的有效时长，该有效时长即为上述的定时时长，例如，定时时长可为2小时、3小时、1.5小时等。在超出该定时时长时，可说明配置的第一小区的优先级参数无效，则可取消第一小区对应的优先级参数的配置，删除配置的第一小区的优先级参数，从而恢复第一小区对应的重选优先级。通过设置降低第一小区对应的重选优先级的有效时长可准确控制终端在第二小区的时间，能够更加灵活地选择小区进行驻留，在降低功耗的同时满足用户的不同需求。
需要说明的是，在本申请的实施例中，终端在驻留到第二小区后，为了使终端在第二小区驻留第二预设时长，终端可以执行以下步骤：在第二预设时长内，禁止恢复第一小区的重选优先级，以及关闭第一小区的背景搜索。
可以理解的是，在本申请的实施例中，终端驻留到第二小区后，为了避免刚驻留到第二小区，又立刻再次进行小区重选，驻留到第一小区的情况，终端即可在一定时长内，即第二预设时长内禁止恢复第一小区的重选优先级，以及关闭第一小区的背景搜索，这样，终端将无法实现从第二小区到第一小区的小区重选，在第二预设时长内维持驻留到第二小区，从而降低终端功耗，避免频繁切换驻留的小区。
在本申请实施例中，可根据终端实际对业务的需求情况降低第一小区对应的重选优先级或恢复第一小区对应的重选优先级，能够保证终端选择合适的小区进行驻留，降低终端功耗，提高终端的续航能力。
图3为本申请实施例提供的一种小区驻留方法的流程示意图二。如图3所示，在一个实施例中，小区驻留方法还可包括以下步骤：
S301、若终端当前驻留的第一小区存在网络异常，则降低第一小区的重选优先级。
终端驻留在第一小区第一预设时长后，若需要通过第一小区对应的网络进行数据传输，则可检测驻留的第一小区是否存在网络异常。可选地， 网络异常可包括但不限于第一小区的配置异常、随机接入(Random Access，RA)失败率大于失败率阈值等，其中，第一小区的配置异常可包括NR小区的物理小区标识异常(如与其它小区存在标识冲突等)、第一小区的功率参数(如参考信号功率等)异常等，但不限于此。随机接入过程是终端与基站的RRC层通过一组消息进行交互的过程，通过此类过程实现RRC对整个协议栈的管理和控制。终端驻留的第一小区存在网络异常，会对终端的正常数据传输产生影响，不利用业务进行。则在检测到驻留的第一小区存在网络异常时，可确定终端满足第一预设条件，从而降低第一小区对应的重选优先级。
S302、重新选择第二小区驻留。
在终端处于空闲态时，由于第一小区降低后的重选优先级为第二重选优先级，低于第二小区的第三重选优先级，则可选择第二小区驻留，并在接入到第二小区对应的网络后，通过该网络进行数据传输。
在一些实施例中，在终端检测到当前驻留的第一小区存在网络异常，并降低第一小区对应的重选优先级后，在终端处于空闲态并进行小区重选时，若搜索到的小区仅包括第一小区而不包括第二小区，终端可对当前驻留的第一小区的相邻小区进行测量，并根据测量的各个小区的信号质量选择信号质量最好的小区进行驻留。
在一些实施例中，也可设置其它降低第一小区对应的重选优先级及恢复第一小区对应的重选优先级的场景。示例性地，可设置降低第一小区对应的重选优先级的第一时间段，当终端处于该第一时间段内，第一小区对应的重选优先级为第二重选优先级，可低于第二小区对应的第三重选优先级。例如，可设置每天的凌晨1点至6点为降低第一小区对应的重选优先级的时间段，在该时间段内，终端可选择驻留在第二小区，当该时间段结束时，可恢复第一小区对应的重选优先级。示例性地，也可设置恢复第一小区对应的重选优先级的第二时间段，当终端处于该第二时间段内，第一小区对应的重选优先级为第一重选优先级，可高于第二小区对应的第三重选优先级。例如，可设置每天的12点到14点、19点到21点为恢复第一小区对应的重选优先级的时间段，在该时间段内，终端可选择驻留在第一小区，当该时间段结束时，可重新降低第一小区对应的重选优先级。
可选地，上述的第一时间段、第二时间段可由用户根据实际需求进行设置，也可根据用户的使用习惯进行设置，可采用用户每日使用终端的使用数据，并根据该使用数据分析用户的使用习惯，可将用户在每日的重度使用时间段设置为恢复第一小区对应的重选优先级的第二时间段，也可将用户在每日的轻度使用时间段设置为降低第一小区对应的重选优先级的第二时间段等，但不限于此。
需要说明的是，降低第一小区对应的重选优先级及恢复第一小区对应的重选优先级的场景并不仅限于上述实施例所描述的几种场景，本申请实 施例对降低第一小区对应的重选优先级及恢复第一小区对应的重选优先级的场景不进行限制。
本申请实施例提供了一种小区驻留方法，应用于终端，方法包括：当终端在第一小区驻留第一预设时长后，若终端满足第一预设条件，则降低第一小区的重选优先级，以使终端驻留到第二小区，第一小区和第二小区为不同网络制式的小区，第一小区的重选优先级高于第二小区的重选优先级；当终端在第二小区驻留第二预设时长后，若终端满足第二预设条件，则恢复第一小区的重选优先级。本申请实施例提供的小区驻留方法，终端在某一小区驻留一定时长后，在满足特定条件的情况下，再进行驻留小区的调整，避免频繁切换驻留的小区，降低了终端的功耗。
