具体实施方式
为了能够更加详尽地了解本申请实施例的特点与技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其他步骤或单元。
应理解，本申请实施例的技术方案可以应用于第四代移动通信系统(the 4th generation mobile communication system，4G)、第五代移动通信系统(the 5th generation mobile communication system，5G)的新无线(New Radio，NR)系统或未来的通信系统，也可以用于其他各种无线通信系统，例如：窄带物联网(Narrow Band-Internet of Things，NB-IoT)系统、全球移动通讯系统(Global System of Mobile communication，GSM)、增强型数据速率GSM演进(Enhanced Data rate for GSM Evolution，EDGE)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、码分多址2000(Code Division Multiple Access，CDMA2000)系统、时分同步码分多址(Time Division-Synchronization Code Division Multiple Access，TD-SCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)等。
图1示出了本申请实施例提供的一种示例性的通信系统框图，该通信系统可以包括：接入网。其中，接入网中包括若干个网络设备11。网络设备11可以是基站，所述基站是一种部署在网络中用以为终端设备12提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在5G系统中，具备基站功能的设备称为gNodeB或者gNB。随着通信技术的演进，“基站”这一描述可能会变化。
另外，该通信系统还可以包括终端设备12。终端设备12也可以称为用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具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、无人机设备以及5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定。网络设备110与终端12之间通过某种空口技术互相通信，例如Uu接口。
相关技术中，终端设备中会存储和维护一个历史驻小区列表，该列表中包括了终端设备在过去一段时间内驻留过的小区的频段，中心频点，小区标识等信息。并且，该列表中包含的小区，根据其频段的优先级顺序和信号强度进行排序。这样，终端设备在开机或者搜网时，会首先按照历史驻留小区列表中小区的信号强度进行小区选择，如果不存在可驻留的小区，则按照初始小区选择方式，在全频段搜索合适的小区，直至搜索到满足条件的小区，然后驻留在该小区。
相关技术中，终端设备是根据历史驻留小区的信号强度进行选择和驻留，并没有考 虑到小区的数据质量。随着通信技术的发展，用户对网络的数据传输质量提出越来越高的要求。如何对数据传输质量较好的小区实现驻留，是目前亟待解决的问题。
为了解决相关技术中的上述问题，本申请实施例提供一种小区驻留方法，可以应用于图1所示的终端设备12中。更进一步地，该方法可以应用于终端设备12的调制解调器中。
其中，终端设备可以从多个历史驻留小区中选择满足驻留条件的小区，得到至少一个候选历史驻留小区；接着，终端设备基于至少一个候选历史驻留小区对应的传输速率信息，从至少一个候选历史驻留小区中确定目标小区；最后，终端设备可以针对该目标小区执行小区驻留操作。也就是说，本申请实施例提供的小区驻留方法，终端设备可以根据历史驻留小区的传输速率信息，从可驻留的候选历史驻留小区中选择一目标小区进行驻留。这样，终端设备可以选择传输质量较好的小区进行驻留，从而提高驻留后小区的数据传输的质量。
下面，结合附图对本申请实施例提供的小区驻留方法进行详细的阐述。
本申请一实施例提供一种小区驻留方法，图2为本申请实施例小区驻留方法的实现流程示意图，如图2所示，所述方法可以包括以下步骤210至步骤230。
步骤210、终端设备从多个历史驻留小区中选择满足驻留条件的小区，得到至少一个候选驻留小区。
应理解，终端设备在开机，或者掉网后重新搜网的情况下，终端设备可以优先对历史驻留小区进行搜索，判断历史驻留小区是否满足驻留条件，从而从满足驻留条件的历史驻留小区中选择一个小区进行驻留，以降低小区搜索时间提高小区驻留效率。
在一些实施例中，终端设备可以存储过去一段时间内多个历史驻留小区的相关信息，或者一定数量的历史驻留小区的相关信息。示例性的，终端设备可以存储终端设备在过去24小时以内的历史驻留小区的相关信息，或者终端设备最多存储30个历史驻留小区的相关信息。本申请实施例对此不做限定。
在一些实施例中，历史驻留小区的相关信息包括但不限于，历史驻留小区的小区标识信息、频段信息、中心频点信息等信息。
进一步地，终端设备可以基于存储的多个历史驻留小区的相关信息，对存储的多个历史驻留小区进行搜索，判断所存储的多个历史驻留小区是否满足驻留条件。
在一些实施例中，驻留条件可以是S准则。即小区的接收功率>0，且小区的接收质量>0。
可以理解的是，终端设备可以在搜索到某个历史驻留小区后，测量该历史驻留小区的信号质量是否满足S准则，若满足S准则，那么确定该历史驻留小区满足驻留条件，将该历史驻留小区确定为一个候选驻留小区。
需要说明的是，终端设备可以逐一地对多个历史驻留小区进行搜索和判断，得到满足驻留条件的一个或多个候选驻留小区。若多个历史驻留小区均不满足驻留条件，则终端设备对当前网络进行全频段搜索，以便得到可以驻留的目标小区。
步骤220、终端设备基于至少一个候选驻留小区对应的传输速率信息，从至少一个候选驻留小区中确定目标小区。
本申请实施例中，终端设备还可以存储每个历史驻留小区的传输速率信息。其中，传输速率信息是指终端设备驻留在一历史驻留小区中时，该历史驻留小区的上行数据传输速率和/或下行数据传输速率。
在一些实施例中，传输速率信息包括但不限于数据传输的平均速率，数据传输的最高速率，数据的均衡速率等。
在一种可能的实现方式中，当终端设备驻留在历史驻留小区中时，终端设备可以在 传输业务数据的过程中，根据业务数据的传输情况，确定该历史驻留小区的传输速率信息，并存储该传输速率信息。即终端设备可以被动地获取历史驻留小区的传输速率信息。
在另一种可能的实现方式中，当终端设备驻留在历史驻留小区中时，终端设备可以主动发起对该历史驻留小区传输速率的测量，根据传输速率的测量结果，得到该历史驻留小区的传输速率信息，并存储该传输速率信息。示例性的，当终端设备驻留在历史驻留小区时，终端设备可以向该小区的网络设备发送测量信号，并接收该网络设备发送的反馈信号，该反馈信号中可以包含网络设备所述测量信号的接收时间，这样终端设备可以根据测量信号的发送时间以及接收时间确定当前的传输速率信息。也就是说，终端设备可以主动地测量历史驻留小区的传输速率信息。本申请实施例对传输速率信息的获取过程不做限定。
本申请实施例中，终端设备在确定了候选驻留小区后，可以根据候选小区的传输速率信息，从至少一个候选驻留小区中确定要驻留的目标小区。
示例性的，终端设备可以从至少一个候选驻留小区中确定传输速率最大的候选驻留小区作为目标小区，终端设备还可以从至少一个候选驻留小区中确定传输速率大于预设阈值的候选驻留小区作为目标小区。本申请实施例对此不做限定。
步骤230、终端设备针对目标小区执行小区驻留操作。
应理解，终端设备在确定了目标小区后，终端设备可以执行小区驻留操作，驻留在该目标小区中。终端设备驻留在该目标小区之后，可以执行网络注册、随机接入等流程，实现上行数据同步。
由此可见，本申请实施例提供的小区驻留方法中，终端设备可以从多个历史驻留小区中选择满足驻留条件的小区，得到至少一个候选历史驻留小区；然后，终端设备基于至少一个候选历史驻留小区对应的传输速率信息，从至少一个候选历史驻留小区中确定目标小区；最后，终端设备可以针对该目标小区执行小区驻留操作。也就是说，本申请实施例提供的小区驻留方法，终端设备可以根据历史驻留小区的传输速率信息，从可驻留的候选历史驻留小区中选择一目标小区进行驻留。这样，终端设备可以选择传输质量较好的小区进行驻留，从而提高驻留后小区的数据传输的质量，优化用户的数据上网体验。
在一些实施例中，终端设备可以存储和维护一个历史驻留小区列表，通过历史驻留小区列表存储上述多个历史驻留小区的相关信息。也就是说，终端设备通过历史驻留小区列表，记录多个历史驻留小区分别对应的小区标识信息、频段信息、中心频点信息等信息。
这样，终端设备在开机，或者掉网后重新搜网的情况下，可以读取历史驻留小区列表。然后，通过历史驻留小区列表中存储的多个历史驻留小区的小区标识信息、频段信息、中心频点信息，对历史驻留小区进行搜索，得到搜索结果。接着，终端设备根据每个历史驻留小区的搜索结果，判断历史驻留小区是否满足驻留条件，进而从满足驻留条件的历史驻留小区中选择一个小区进行驻留。
在一些实施例中，上述历史驻留小区列表中还可以存储每个历史驻留小区的传输速率信息。
基于此，步骤220中终端设备基于至少一个候选驻留小区对应的传输速率信息，从至少一个候选驻留小区中确定目标小区，包括：
终端设备从历史驻留小区列表中，获取至少一个候选驻留小区对应的传输速率信息；
终端设备基于至少一个候选驻留小区对应的传输速率信息，从至少一个候选驻留小区中确定目标小区。
可以理解的是，终端设备在确定了至少一个候选驻留小区后，可以从历史驻留小区 列表中读取每个候选驻留小区分别对应的传输速率信息。并基于每个候选驻留小区的传输速率信息，从至少一个候选驻留小区中确定要驻留的目标小区。
在一些实施例中，历史驻留小区列表中的多个历史驻留小区是按照历史驻留小区的传输速率的大小排序的。
其中，历史驻留小区列表中的多个历史驻留小区可以根据传输速率由大到小进行排列，也可以根据传输速率由小到大进行排列。本申请实施例对此不做限定。
这样，终端设备可以根据历史驻留小区列表中多个历史驻留小区的排列顺序，逐一地对历史驻留小区进行搜索和判断，若满足驻留条件，则确定该历史驻留小区为候选驻留小区并读取其对应的传输速率信息。
在一些实施例中，终端设备通过接入层协议栈的历史小区维护模块记录和维护终端设备驻留过的小区的相关信息列表，并且根据传输速率对多个历史驻留小区进行排序。
在一些实施例中，步骤220中终端设备基于至少一个候选驻留小区对应的传输速率信息，从至少一个候选驻留小区中确定目标小区，可以通过以下方式实现：
终端设备基于至少一个候选驻留小区对应的传输速率信息，从至少一个候选驻留小区中确定传输速率满足选择条件的小区，得到目标小区。
其中，选择条件包括以下中的至少一个：
传输速率为至少一个候选历史驻留小区中传输速率最大的小区；
传输速率大于速率阈值。
在一些实施例中，当候选驻留小区的数量仅为一个的情况下，终端设备可以直接将该候选驻留小区确定为目标小区。或者，终端设备可以判断该候选驻留小区的传输速率是否大于速率阈值，若大于速率阈值，则终端设备将该候选驻留小区确定为目标小区。
在一些实施例中，当候选驻留小区的数量包括多个的情况下，终端设备可以根据每个候选驻留小区的传输速率信息，从多个候选驻留小区中选择传输速率最大的小区作为将要驻留的目标小区，或者从多个候选驻留小区中选择传输速率大于速率阈值的小区作为将要驻留的目标小区。
这里，若传输速率大于速率阈值的候选驻留小区的数量为多个，则终端设备进一步从多个传输速率大于速率阈值的候选驻留小区中，选择传输速率最大的小区作为将要驻留的目标小区。
在一些实施例中，当候选驻留小区的数量包括多个的情况下，终端设备可以按照每个候选驻留小区的数据传输速率对多个候选驻留小区进行排序，按照传输速率的由高到低的顺序，对多个候选驻留小区尝试驻留。
在一些实施例中，在终端设备维护的历史小区列表中的多个历史驻留小区根据传输速率大小排序的情况下，终端设备可以直接根据候选驻留小区的排列顺序，从候选驻留小区中选择排序在最前(或最后)的候选驻留小区，作为将要驻留的目标小区。如此，可以节省电子设备的计算资源，提高小区的驻留效率。
实际应用中，候选驻留小区还可以配置驻留的优先级顺序。候选驻留小区的优先级顺序可以与网络的无线接入制式相关。例如，终端设备可以优先接入采用5G网络的候选驻留小区中，当候选驻留小区中没有采用5G制式的小区时，终端设备可以选择采用LTE网络的候选驻留小区。
在一些实施例中，终端设备可以结合候选驻留小区的传输速率，以及候选驻留小区的优先级顺序，确定目标小区。
示例性的，终端设备可以优先选择优先级高的候选驻留小区，若优先级高的候选驻留小区的数量为多个，则终端设备可以从多个高优先级的候选驻留小区中选择传输速率最高的候选驻留小区作为目标小区。
在本申请一实施例中，参考图3所示的流程示意图，步骤210中终端设备从多个历史驻留小区中选择满足驻留条件的小区，得到至少一个候选历史驻留小区之前，还可以执行以下步骤：
步骤202、终端设备在接入第一小区的情况下，获取第一小区的传输速率信息；
步骤204、终端设备基于第一小区的传输速率信息，构建历史驻留小区列表。
其中，第一小区为多个历史驻留小区中的任意一个。
也就是说，终端设备在驻留并接入任意一个小区时，终端设备可以获取该小区的传输速率信息，以及该小区的其他相关信息，例如小区标识信息、频段信息、中心频点信息等。
这样，终端设备在获取到小区的传输速率信息，以及其他相关信息后，可以根据传输速率信息，以及该小区的其他相关信息构建历史驻留小区列表，以便于终端设备在下一次搜网或者开机时使用该历史驻留小区列表进行小区驻留。
在一些实施例中，若终端设备中已经存储有历史驻留小区列表，则终端设备可以将上述第一小区的传输速率信息，以及其他相关信息，更新至历史驻留小区列表中。
在一些实施例中，终端设备更新历史驻留小区列表时，可以基于第一小区的传输速率信息确定第一小区在历史驻留小区列表中的排列位置，使得位于第一小区之前的历史驻留小区的速率信息小于第一小区的传输速率，位于第一小区之后的历史驻留小区的速率信息大于第一小区的传输速率。
在一些实施例中，步骤202中终端设备在接入第一小区的情况下，获取第一小区的传输速率信息，可以通过以下步骤实现：
步骤2021、终端设备在接入第一小区时，向网络设备发送测量信号；
步骤2022、接收网络设备的反馈信号，基于反馈信号确定第一小区的传输速率信息。
在本申请实施例中，终端设备驻留在任意一个小区时，可以主动发起对该驻留小区的传输速率的测量，统计一段时间内的平均速率、最高速率、或者均衡速率中的至少一个。
其中，终端设备可以向当前驻留的第一小区所对应的网络设备发送测量信号，并接收网络设备基于该测量信号发送的反馈信号。这样，终端设备可以基于测量信号，以及反馈信号，确定第一小区的传输速率信息。
示例性的，反馈信号中可以包括测量信号的接收时间。基于此，终端设备可以基于测量信号的发送时间，测量信号的接收时间，确定第一小区的传输速率信息。
在一些实施例中，测量信号可以是终端设备发送给网络设备的业务数据，也可以是专用于传输速率测量的信号。本申请实施例对此不做限定。
这样，终端设备在下一次开机或者进行搜网时，终端设备可以根据历史驻留小区的传输速率信息，从可驻留的候选历史驻留小区中选择一目标小区进行驻留。如此，终端设备可以基于传输速率速率选择传输速率较高的小区进行驻留，从而提高驻留后小区的传输质量。
在本申请一实施例中，本申请实施例还提供一种历史驻留小区列表生成方法，参考图4所示的流程示意图，历史驻留小区列表生成方法可以包括步骤410和步骤420。
步骤410、终端设备在接入第一小区的情况下，获取第一小区对应的传输速率信息；第一小区为所述终端设备多个历史驻留小区中的任意一个；传输速率信息用于使终端设备从多个历史驻留小区中确定执行小区驻留操作的目标小区；
步骤420、终端设备基于第一小区对应的传输速率信息，构建历史驻留小区列表。
可以理解的是，终端设备在驻留并接入任意一个小区时，终端设备可以获取该小区的传输速率信息，以及该小区的其他相关信息，例如小区标识信息、频段信息、中心频 点信息等。
这样，终端设备在获取到小区的传输速率信息，以及其他相关信息后，可以根据传输速率信息，以及该小区的其他相关信息构建历史驻留小区列表，以便于终端设备在下一次搜网或者开机时使用该历史驻留小区列表进行小区驻留。
在一些实施例中，若终端设备中已经存储有历史驻留小区列表，则终端设备可以将上述第一小区的传输速率信息，以及其他相关信息，更新至历史驻留小区列表中。
在一些实施例中，终端设备更新历史驻留小区列表时，可以基于第一小区的传输速率信息确定第一小区在历史驻留小区列表中的排列位置，使得位于第一小区之前的历史驻留小区的速率信息小于第一小区的传输速率，位于第一小区之后的历史驻留小区的速率信息大于第一小区的传输速率。
在一些实施例中，终端设备驻留在任意一个小区时，可以主动发起对该驻留小区的传输速率的测量，统计一段时间内的平均速率、最高速率、或者均衡速率中的至少一个。
在本申请实施例中，终端设备在接入第一小区时，向该第一小区对应的网络设备发送测量信号；并且终端设备接收网络设备的反馈信号，基于反馈信号确定第一小区的传输速率信息。
在本申请实施例中，终端设备可以向网络设备发送测量信号，并接收网络设备基于该测量信号返回的反馈信号。这样，终端设备可以基于测量信号，以及反馈信号，确定第一小区的传输速率信息。
在一些实施例中，测量信号可以是终端设备发送给网络设备的业务数据，也可以是专用于传输速率测量的信号。本申请实施例对此不做限定。
由此可见，本申请实施例提供的历史驻留小区列表生成方法中，终端设备可以在历史驻留小区列表中存储终端设备驻留过的小区的传输速率信息，这样，终端设备在下一次开机或者进行搜网时，终端设备可以根据历史驻留小区的传输速率信息，从可驻留的候选历史驻留小区中选择一目标小区进行驻留。这样，终端设备可以基于传输速率速率选择传输质量较好的小区进行驻留，从而提高驻留后小区的传输质量。
下面，结合具体应用场景，对本申请实施例提供的小区驻留方法进行详细阐述。
参考图5所示的流程示意图，终端设备驻留在一小区时，终端设备可以记录当前小区的传输速率信息，以及当前小区的相关信息。
其中，当前小区的相关信息包括但不限于当前小区的小区标识信息，频段信息，中心频点信息等。
另外，小区的传输速率信息包括但不限于，一段时间内的平均速率、最高速率、均衡的速率。
进一步地，参考图5所示，终端设备可以根据当前小区的传输速率信息，将当前小区的相关信息存储至历史驻留小区列表中。
本申请实施例中，终端设备可以将当前小区和所有历史驻留小区按照传输速率信息进行排序，确定当前小区在历史驻留小区列表中的位置，并将当前小区的相关信息按照确定的位置进行存储，得到历史驻留小区列表。
在一些实施例中，终端设备的接入层协议栈的历史小区维护模块记录和维护驻留过的小区的历史信息列表，并且根据数据业务速率的算法进行排序。
参考图6所示的流程示意图，终端设备在开机或者进行网络搜索时，获取历史驻留小区列表。进一步地，终端设备根据历史驻留小区列表，对历史驻留小区列表中存储的多个历史小区进行搜索，从多个历史驻留小区中确定满足驻留条件的候选驻留小区。
终端设备在得到候选驻留小区之后，按照候选驻留小区的传输速率对候选驻留小区进行排序。进一步地，终端设备依次选择数据速率最优的小区进行驻留。
这样，终端设备可以基于传输速率信息确定目标小区，从而得到当前环境中速率最优的小区。如此，从用户的实际需出发，优化用户的数据上网体验。
本申请实施例通过的小区驻留方案，优化了3GPP的协议规范，在小区驻留时进行一步考虑小区的传输速率信息，从而选择到当前环境中速率最优的小区。从用户的实际需求出发，优化用户的数据上网体验。
