请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个用户设备110以及若干个基站120。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110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，用户设备110可以是物联网用户设备，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网用户设备的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线用户设备。或者，用户设备110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为新一代无线接 入网(New Generation-Radio Access Network，NG-RAN)。
其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体接入控制(Medium Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，用户设备110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的车对车(vehicle to vehicle，V2V)通信、车对路边设备(vehicle to Infrastructure，V2I)通信和车对人(vehicle to pedestrian，V2P)通信等场景。
这里，上述用户设备可认为是下面实施例的终端设备。
在一些实施例中，上述无线通信系统还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中，网络管理设备130可以是无线通信系统中的核心网设备，比如，该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备130的实现形态，本公开实施例不做限定。
为了更好地理解本公开任一个实施例所描述的技术方案，首先，对相关技术中小区重选进行部分说明：
在一个应用场景中，在NTN网络中，若卫星进行反馈链路切换(feeder link switch)或者UE进行业务链路切换(service link switch)时，会导致UE进行小区重选。由于在进行反馈链路切换，基站会突然故不可用；若UE根据S准则启动对邻小区的测量可能会导致还没启动邻小区测量，而服务小区突然不可用；如此会导致UE过晚的进行小区重选。
在一个实施例中，NTN网络支持的网络类型包括：地面移动(earth moving)类型、地面固定(earth fixed)类型或地面准固定(quasi earth fixed)类型。而对于该些网络类型的情况下，UE如何确定小区重选时刻是亟待解决的问题。
如图2所示，本公开实施例提供一种小区重选方法，由UE执行，包括：
步骤S21：接收时间信息；
步骤S22：根据时间信息及小区重选状况，确定小区重选时刻。
在一个实施例中，UE可以为各种移动终端或固定终端。例如，UE可以是但不限于是手机、计算机、服务器、可穿戴设备、游戏控制平台或多媒体设备等。
本公开实施例提供一种小区重选方法，由UE执行，可包括：接收网络设备发送的时间信息。
在一个实施例中，网络设备可以是NTN网络设备。示例性的，网络设备可以包括但不限于以下之一：卫星、基站、核心网设备等。此处的基站可以是3G基站、4G基站、5G基站或其它演进型基站。此处的核心网设备可以是但不限于是核心网的各种物理实体或者逻辑实体；例如核心网设备可以是移动性管理实体或者服务网关等。
在一个实施例中，时间信息可以是世界标准时间(UTC)的时间信息。当然，在其它实施例中，该时间信息也可以是星历参考时间、北京时间等。
该时间信息可为指示UE进行某一个或多个重选状况的重选时刻。
在一实施例中，小区重选时刻为UE开始进行邻小区测量的时刻。
在一个实施例中，小区重选状况包括但不限于以下至少之一：
网络类型；
时间信息涉及的应用场景。
此处的网络类型可以是指UE的服务小区的网络类型。
在一个实施例中，网络类型，包括但不限于以下之一：
地面移动类型，指示卫星波束覆盖在地球上的区域移动的NTN网络类型；
地面固定类型，指示卫星波束覆盖在地球上的区域固定的NTN网络类型；
地面准固定类型，指示在预定时间内卫星波束覆盖在地球上的第一区域固定、且达到预定时间时卫星波束覆盖在地球上的第二区域的NTN网络类型。
例如同步卫星可以是指地面固定类型的一种形式。
此处的卫星波束覆盖在地球上的区域移动，也可以认为是卫星信号覆盖在地球上的区域相对于地面预定位置移动。此处的卫星波束覆盖在地球上的区域固定，也可以认为是卫星信号覆盖在地球上的区域相对于地面预定位置静止。此处的在预定时间内卫星波束覆盖在地球上的第一区域固定且达到预定时间时卫星波束覆盖在地球上的第二区域，也可以认为是：在预定时间内卫星信号覆盖在地球上的区域相对于地面预定位置静止，在预定时间后卫星信号覆盖在地球上的区域相对于地面位置移动。此处的卫星波束覆盖在地球上的区域或者卫星信号覆盖在地球上的区域，可以认为是UE的服务小区覆盖的区域。
例如，UE可能接收到时间信息。此时，若UE的当前服务小区是属于地面移动类型的NTN网络，则UE会根据时间信息确定地面移动类型的NTN网络的小区重选时刻，若UE的当前服务小区是属于地面固定类型的NTN网络，则UE会根据时间信息确定地面固定类型的NTN网络的小区重选时刻。
在一个实施例中，应用场景，包括但不限于以下之一：
业务链路切换触发的小区重选场景；
反馈链路切换触发的小区重选场景。
此处的业务链路可以是指UE与卫星或基站之间的链路。此处的反馈链路可以是指基站或者卫星与核心网、或者基站或卫星与卫星网关之间的链路。
在本公开公开实施例中，UE可以通过时间信息及小区重选状况，确定出小区重选时刻，从而可以基于该重选时刻进行小区重选。如此，本公开实施例相对于相关技术中基于服务小区的信号测量结果进行小区重选来说，可以降低UE的服务小区已不可用而没有启动邻小区进行测量的情况出现，可以使得UE在不基于服务小区的测量结果的情况下，仅仅根据预先接收的时间信息和小区重选状况，更早且更快速的确定出小区重选时刻；从而减少实际上需要小区重选时，因为确定小区重选时刻的不及时或者无法确定导致的小区重选进程慢。且，还可以减少UE在小区重选过程中由于服务小区移动等而无法使得无线信号覆盖UE的情况，提高小区重选成功率。
在一个实施例中，网络类型和/或应用场景基于接收的携带时间信息的第一消息的字段确定。
在一个实施例中，时间信息携带在第一消息的不同字段时，指示网络类型不同和/或时间信息涉及的应用场景不同。
本公开实施例提供一种小区重选方法，由UE执行，可包括：接收第一消息，其中，第一消息携带时间信息。示例性的，第一消息包括但不限于是系统消息、无线资源控制(RRC)信令。
本公开实施例提供一种小区重选方法，由UE执行，可包括：接收第一消息；其中，第一消息的第一预定字段携带时间信息，指示网络类型为地面移动类型和/或时间信息涉及反馈链路切换触发的小区重选场景。
本公开实施例提供一种小区重选方法，由UE执行，可包括：接收第一消息；其中，第一消息的第二预定字段携带时间信息，指示网络类型为地面准固定类型和/或时间信息涉及业务链路切换触发的小区重选场景。
如此，在本公开实施例中可以通过携带时间信息在第一消息中的不同字段，指示不同的网路类型和/或应用场景；从而使得UE仅需接收携带时间信息的第一消息，并可知晓网络配置的时间信息及小区重选状况；从而可以减少信令的传输、节省系统资源。
在一个实施例中，网络类型和/或应用场景基于接收的指示信息确定。示例性的，该指示信息也可以是通过系统消息或者RRC信令发送。此处的指示信息不携带在所述第一消息中；即携带指示信息的系统消息与携带时间信息的第一消息不是同一个消息，或者，携带指示信息RRC信令与携带时间信息的第一消息不是同一个消息。
在一个实施例中，指示信息包括类型指示信息；其中，类型指示信息包括以下之一：
第一类型指示信息，用于指示网络类型为地面移动类型；
第二类型指示信息，用于指示网络类型为地面固定类型；
第三类型指示信息，用于指示网络类型为地面准固定类型。
在一个实施例中，指示信息包括切换指示信息；其中，切换指示信息包括以下之一：
第一切换指示信息，用于指示时间信息涉及业务链路切换触发的小区重选场景；
第二切换指示信息，用于指示时间信息涉及反馈链路切换触发的小区重选场景。
如此，在本公开实施例中，可以通过UE接收的指示信息，确定当前网络的网络类型和/或时间信息涉及的应用场景；从而可以确定出准确的小区重选状况。
本公开实施例提供的一种小区重选方法，由UE执行，可包括：若指示信息中不包括切换指示信息，时间信息涉及业务链路切换触发的小区重选场景和反馈链路切换触发的小区重选场景。
示例性的，若UE接收指示信息，其中指示信息仅包括第一类型指示信息；则UE确定UE所在的服务小区为地面移动类型，且该时间信息涉及的可以是涉及业务链路切换触发的小区重选场景、也可以涉及反馈链路切换触发的小区重选场景。
如此，在本公开实施例中，若指示信息不携带切换指示信息，也可以通过无指示，确定出时间信息涉及的应用场景。
在一个实施例中，若UE的服务小区为地面移动类型，一个服务小区关联一个或两个时间信息。
示例性的，UE的服务小区为地面移动类型。若一个服务小区关联一个时间信息；该时间信息可以是涉及业务链路切换触发的小区重选场景，或者该时间信息可以是涉及反馈连链路切换触发的小区重选场景。若该时间信息涉及反馈链路切换触发的小区重选场景时，该时间信息可以供该服务小区内所有的UE进行小区重选使用。
在一个实施例中，若一个服务小区关联两个时间信息，其中一个时间信息涉及业务链路切换触发的小区重选场景，另一个时间信息涉及反馈链路切换触发的小区重选场景。
示例性的，UE的服务小区(即UE所有在网络的网络类型)为地面移动类型。若一个服务小区关联两个时间信息；其中一个时间信息涉及业务链路切换触发的小区重选场景，另一个时间信息涉及反馈链路切换涉及反馈链路切换触发的小区重选场景。若另一个时间信息涉及反馈链路切换触发的小区重选场景时，该时间信息可以供服务小区内所有的UE进行小区重选使用。
由于业务链路是UE与卫星或者基站之间的链路，若涉及到业务链路切换触发的小区重选的场景时，对于一个服务小区的UE可以关联不同的时间信息，以使得各UE能够基于各自的时间信息确定出各自的小区重选时刻。而由于反馈链路是指基站或者卫星与核心网之间的链路；若涉及到反馈链路切换触发的小区重选场景时，对于一个服务小区内的所有UE都可以关联一个相同的时间信息；该时间信息可以供该服务小区内所有的UE确定小区重选时刻。
在一个实施例中，若UE的服务小区为地面准固定类型，一个服务小区关联一个时间信息。
示例性的，UE的服务小区(即UE所在网络的网络类型)为地面准固定类型，一个服务小区关联一个时间信息；该时间信息可以涉及业务链路切换会触发的小区重选场景或者反馈链路切换触发的小区重选场景；该时间信息可以供该服务小区内所有UE确定小区重选时刻。
示例性的，UE可以接收网络设备广播的时间信息。
由于UE所在的网络为地面准固定类型；则UE在重选过程中服务小区不会移动或者预定时间内 不会移动；则对于某个服务小区的时间信息可以适用该服务小区内所有的UE。
如此，当UE的服务小区为地面准固定类型时，则可以对于一个服务小区关联一个时间信息；如此该服务小区内所有UE均可以基于该时间信息确定小区重选时刻；如此可以减少针对一个服务小区内传输时间信息的传输资源。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。
如图3所示，本公开实施例提供一种小区重选方法，由UE执行，包括：

示例性的，UE确定UE所在网络类型为地面移动类型，且确定接收到的时间信息仅涉及反馈链路切换触发的小区重选场景；则UE基于该时间信息确定反馈链路切换触发的小区重选时刻。则UE在该小区重选时刻开始进行小区重选操作，如进行邻小区的测量。
示例性的，UE确定UE接收到的时间信息仅涉及反馈链路切换触发的小区重选场景，则UE基于该时间信息确定反馈链路切换触发的小区重选时刻。则UE在该小区重选时刻开始进行小区重选操作，如进行邻小区的测量。

在一个实施例中，方法还包括：

示例性的，UE确定UE所在网络类型为地面移动类型，且确定接收到的时间信息仅涉及反馈链路切换触发的小区重选场景；则UE基于该时间信息确定反馈链路切换触发的小区重选时刻。且UE在该小区重选时刻之前，基于小区重选准则进行邻小区的测量，并基于测量结果确定业务链路切换触发的小区重选。
示例性的，UE确定UE接收到的时间信息仅涉及反馈链路切换触发的小区重选场景，则UE基于该时间信息确定反馈链路切换触发的小区重选时刻。且UE在该小区重选时刻之前，基于小区重选准则进行邻小区的测量，并基于测量结果确定业务链路切换触发的小区重选。
示例性的，UE确定UE所在网络类型为地面移动类型，则UE基于接收到的时间信息确定反馈链路切换触发的小区重选时刻。且UE在该小区重选时刻之前，基于小区重选准则进行邻小区的测量，并基于测量结果确定业务链路切换触发的小区重选。
这里，若UE在小区重选时刻之前，基于小区重选准则完成了业务链路切换触发的小区重选，则可以无需在小区重选时刻时进行反馈链路切换触发的小区重选。
在本公开实施例中，UE还可以在反馈链路切换触发的小区重选时刻之前，基于小区重选准则，确定业务链路切换触发的小区重选；从而可以在该小区重选时刻之前，应对业务链路切换触发的小区重选；从而提高进一步提高小区重选的成功率。
如图4所示，本公开实施例提供一种小区重选方法，由UE执行，包括：
步骤S41：响应于网络类型为地面移动类型且服务小区关联两个时间信息，基于两个时间信息中较早的时间信息，确定小区重选时刻。
示例性的，UE确定UE所在网络类型为地面移动类型，且UE确定接收到针对服务小区的两个时间信息。其中该两个时间信息中第一时间信息早于第二时间信息；则UE确定第一时间信息为小 区重选时刻。例如，两个时间信息为9点5分及9点10分，则确定9点5分开始进行邻小区测量。
这里，该两个时间信息中任意一个时间信息可以涉及业务链路切换触发的小区重选场景或者反馈链路切换触发的小区重选场景。
在一个实施例中，步骤S22，包括：
响应于网络类型为地面移动类型且服务小区关联两个时间信息，基于两个时间信息中较早的时间信息，确定小区重选时刻。
在本公开实施例中，若网络类型为地面移动类型且该服务小区关联两个时间信息，则无论该两个时间信息涉及的是何种应用场景；则UE均可以基于较早的时间信息确定小区重选时刻。如此，本公开实施例可以在相对较早的时间进行重选，从而可以使得UE更早的连接到小区进行通信；如此可以降低UE链路断开的情况出现、提高UE通信连接的稳定性。
如图5所示，本公开实施例提供一种小区重选方法，由UE执行，包括：
步骤S51：响应于网络类型为地面移动类型且时间信息涉及业务链路切换触发的小区重选场景，基于时间信息，确定业务链路切换触发的小区重选时刻。

在一个实施例中，步骤S22，包括：
响应于网络类型为地面移动类型且时间信息涉及业务链路切换触发的小区重选场景，基于时间信息，确定业务链路切换触发的小区重选时刻。
如此，在本公开实施例中，可以在网络类型为地面移动类型时，基于涉及业务链路切换触发的小区重选场景的时间信息，确定业务链路切换触发的小区重选；如此可以实现确定业务链路切换触发的小区重选的小区重选时刻。且本公开实施例相对于相关技术中基于服务小区的信号测量结果确定小区重选来说，可以减少获得相对较早的小区重选时刻以及小区重选过程中无法使得信号覆盖UE的情况，提高小区重选成功率。

在本公开实施例中，无论UE所在的网络类型为地面准固定类型时，可以基于时间信息确定小区重选时刻；如此相对通过接收的网络设备时间信息确定出小区重选时刻，可以在相对较早的时间进行小区重选，从而可以降低UE链路断开的情况出现及提高UE通信连接的稳定性。
