Description

一种小区重选方法、小区重选装置及存储介质 技术领域
本公开涉及无线通信技术领域，尤其涉及一种小区重选方法、小区重选装置及存储介质。
背景技术
在相关通信技术中，支持基于陆地网络(terrestrial networks，TN)进行通信。在基于陆地网络进行通信时，终端主要基于S准则和R准则进行小区重选。例如，终端在进行小区的重选时，可以基于服务小区信号质量对相邻小区服务质量进行测量，并基于R准则对相邻小区测量的结果进行排序，并基于测量结果和排序结果进行目标小区的重选。

图1是根据一示例性实施例示出的一种网络设备与终端的通信***架构图。本公开提供的通信方法可以应用于图1所示的通信***架构图中。如图1所示，网络侧设备可以基于图1所示的架构发送信令。
可以理解的是，图1所示的网络设备与终端的通信***仅是进行示意性说明，无线通信***中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信***中包括的网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例的无线通信***，是一种提供无线通信功能的网络。无线通信***可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)***中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还 可以为NR***中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信***时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信***时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
在通信技术中，基于陆地网络侧设备进行通信，终端在进行小区的重选时，可以基于S准则对相邻小区服务质量进行测量，并基于R准则对相邻小区测量的结果进行排序，并进行目标小区的重选。
其中，S准则包括小区选择电平S rxlev大于零，和小区选择质量S qual大于零。即，S rxlev>0和S qual>0。终端选择/重选的小区需要满足上述S准则。
其中，Srxlev基于测量小区的RSRP值(Q rxlevmeas)小区中所需的最低接收电平(Q rxlevmin)，最低接收电平偏移量(Q rxlevminoffset)，小区功率相关参数(P compensation)，临时应用于小区的偏移值(Q offsettemp)确定。其中P compensation用于惩罚达不到小区最大功率的UE。p Compensation＝max(p Max–p uMax,0)(dB)，其中p Max为小区允许UE的最大上行发射功率、p uMax为UE能力支撑的最大上行发射功率。可参见如下公式。
S rxlev＝Q rxlevmeas–(Q rxlevmin+Q rxlevminoffset)–P compensation-Q offsettemp
S qual基于测量小区的RSRQ值(Qqualmeas)，最小接收信号质量(Q qualmin)，最小接收信号接收质量偏置值(Q qualminoffset)，Q offsettemp确定。可参见如下公式。
S qual＝Q qualmeas–(Q qualmin+Q qualminoffset)-Q offsettemp
进一步地，S rxlev，S qual，Q rxlevmeas，Q rxlevmin，Q rxlevminoffset，Q offsettemp，Qqualmeasp，Q qualmin，Q qualminoffset，C ompensation可参见如下表1。

Figure PCTCN2021084782-appb-000003
Figure PCTCN2021084782-appb-000004
终端可以根据上述S准则，确定对相邻小区进行测量的时间，其规则包括：
对于同频邻小区测量，如果服务小区的S rxlev>S IntraSearchP，则终端可以选择不对邻小区进行测量。相反，如果服务小区的S rxlev<S IntraSearchP，则终端可以选择对邻小区进行测量UE需要对邻小区进行测量。
对于异频邻小区测量，如果邻小区的频率优先级小于等于服务小区的频率优先级，那么如果服务小区的S rxlev>S nonIntraSearchP，则终端可以选择不对邻小区进行测量。相反，如果邻小区的频率优先级小于等于服务小区的频率优先级，那么如果服务小区的S rxlev<S nonIntraSearchP，终端需要对邻小区进行测量。
相关技术中，R准则包括如下公式。
Rs＝Q meas,s+Q hyst–Q offsettemp，Rn＝Q meas,n-Q offset-Q offsettemp
其中，Rs为服务小区的R值，Rn为邻小区的R值，Qmeas,s为服务小区的RSRP 测量值，Q meas,n为邻小区的RSRP测量值，Q hyst为小区重选迟滞值，Q offset为临时偏移值；Q offset为偏移值。具体如下表2。
表2
Figure PCTCN2021084782-appb-000005
当终端对邻小区进行测量时，会根据上述R准则计算每个小区的R值，并且终端只对满足S准则的邻小区进行R准则排序。
在新一代通信技术中引入NTN，NTN基于卫星进行通信。当卫星进行feeder link switch或者进行service link switch时，与终端通信的网络侧设备会突然停止服务。在非陆地网络中，如果根据S准则启动对邻小区的测量，可能会导致，未启动相邻小区服务质量的测量，而与终端通信的网络侧设备已经停止服务的情况。
相关技术中，NTN可以确定停止服务该区域的信息和/或有关新的即将到来的小区的定时信息(例如计时器或绝对时间)。如果需要该两种类型的时间信息，则从***信息和/或星历表中获悉FFS。即，NTN可以提供信息用于协助终端进行小区重选。其中，信息可以是服务小区能够提供服务/停止服务的时间信息，该信息用于触发UE对邻小区进行测量。信息还可以是即将给终端可能给终端提供服务的邻小区的时间信息，用于协助终端选择合适的邻小区。
因此，本公开提供一种小区重选方法。利用NTN提供的服务小区能够提供服务/停止服务的时间信息，和/或，即将给终端可能给终端提供服务的邻小区的时间信息，触发终端提前进行小区重选，避免当卫星进行feeder link switch或者进行service link switch时，导致未启动相邻小区服务质量的测量，而与终端通信的网络侧设备已经停止服务的情况。
图2是根据一示例性实施例示出的一种小区重选方法的流程图。如图2所示，小区重 选方法用于终端中，包括以下步骤。
在步骤S11中，接收第一消息。
在本公开实施例中，第一消息包括用于触发终端进行小区重选的时间信息。其中，时间信息可以包括以下至少一种：
服务小区可以提供服务的时间信息。
服务小区停止服务的时间信息。以及
即将提供服务的邻小区的时间信息。
