技术领域
本公开实施例涉及通信技术领域，具体涉及一种驻留(camp on)的方法和设备。
背景技术
随着移动通信技术的发展，引入了越来越多的提高通信效率的技术。例如：
(1)关于带宽部分(Band Width Part，BWP)介绍：
在第五代移动通信(fifth-generation，5G)系统中，用户设备(User Equipment，UE)可能只能支持一个比较小的工作带宽(例如5MHz)，而网络侧的一个小区会支持比较大的带宽(例如100MHz)，该比较大的带宽中的UE工作的小带宽部分则认为是BWP。
网络侧给UE配置一个或多个BWP，并通过激活或去激活BWP的方式变换UE可以工作的BWP。
网络侧会配置1个默认的BWP(default BWP)，当UE工作在该小区的其他BWP的时候，网络侧可以给UE配置一个在该小区的其他BWP工作的定时器，当该定时器超时时，UE会切换回该default BWP。
(2)关于多波束(beam)的介绍：
未来5G系统中，为达到下行链路传输速率20Gbps和上行链路传输速率10Gbps的目标，将会引入高频通信和大规模天线技术。高频通信可提供更宽的系统带宽，天线尺寸也可以更小，更加有利于大规模天线在基站和UE中部署。基站侧多波束/多收发节点(Multi-beam/Multi-TRP)发送和接收，UE侧多波束(Multi-beam)的发送和接收将会广泛应用。以新空口(New Radio， NR)物理上行共享信道(Physical Uplink Sharing Channel，PUSCH)为例，参见图1，图中示出了上行链路Multi-beam传输的流程，图1中所示的通信系统包括UE11、TRP12、第一PUSCH 13和第二PUSCH 14。
(3)关于长期演进(Long Term Evolution，LTE)小区选择和重选的介绍：
对于LTE的空闲(IDLE)UE来说，需要在一个小区进行驻留，从而能够接收到网络侧的寻呼消息，以及在该驻留小区发起连接建立过程。而寻找该驻留小区的过程包括：小区选择和小区重选，其中：
然而，在5G系统中，一个小区下会有多个BWP或beam，而IDLE或INACTIVE(非激活)状态的UE会检测到一个或多个BWP和一个或多个beam，此时如果UE在任意BWP或beam驻留，可能会导致某一个BWP或一个beam拥塞。

为了便于理解驻留小区的过程，下面对驻留小区的过程中的小区选择和小区重选进行介绍：
a、小区选择：用于UE在还没有驻留小区的时候选择一个可以驻留的小区。小区选择准则被称为S准则，当某个小区的信道质量满足S准则之后，就可以选择为驻留小区。S准则的内容如下：Srxlex>0和Squal>0，其中：
Srxlex＝Q rxlevmeas–(Q rxlevmin+Q rxlevminoffset)–P compensation–Qoffset temp；
Squal＝Q qualmeas–(Q qualmin+Q qualminoffset)–Qoffset temp；
其中，Srxlex表示小区选择接收信号强度；Squal表示小区选择接收信号质量；Qoffset temp表示小区的临时偏移量；Q rxlevmeas表示测量小区的RSRP(参考信号接收功率)值；Q qualmeas表示测量小区的RSRQ(参考信号接收质量)值；Q rxlevmin表示小区的RSRP最小接收强度要求；Q qualmin表示小区的RSRQ最小接收质量要求；Q rxlevminoffset表示当驻留在VPLMN(拜访公共陆地移动网络)上搜索高优先级PLMN(公共陆地移动网络)的时候，采用S rxlex评估小区质量，需要对Q rxlevmin进行的偏移；Q qualminoffset表示当驻留在VPLMN上搜索高优先级PLMN的时候，采用Squal评估小区质量，需要对Q qualmin进行的偏移；P compensation表示补偿值。
b、小区重选：用于在UE已经有了一个可驻留的小区时，由于UE移动而换一个可驻留的小区。小区重选分为：同频和相同优先级的异频小区重选；以及，不同优先级的异频小区重选。
对于同频和相同优先级的异频小区重选，采用R准则。其中，R准则的内容如下：
R s＝Q meas,s+Q Hyst–Qoffset temp+Qoffset SCPTM；
Rn＝Q meas,n–Qoffset–Qoffest temp+Qoffest SCPTM；
其中，R s表示服务小区的信号质量，R n表示邻小区的信号质量。UE重选的小区为信号质量最好(即R s和R n中的最大值)的小区。
Q meas,s表示小区重选过程中用的RSRP测量量；
Qoffset：对于同频重选：如果配置了小区间偏移量Qoffset s,n，Qoffset等于Qoffset s,n，否则Qoffset等于零。对于异频重选：如果配置了小区间偏移量Qoffset s,n，Qoffset等于Qoffset s,n加频率间偏移量Qoffset frequency，否则Qoffset等于Qoffset frequency；
Qoffset temp表示小区的临时偏移量；
Qoffset SCPTM表示用于SC-PTM(单小区点到多点)频点的临时偏移量，如果配置了Qoffset SCPTM，则不使用Qoffset；
Q Hyst表示基于速度的缩放因子，在高速移动状态时取值为sf-High，在中速移动状态时取值为sf-Medium。其他状态，不采用该因子。当UE在规定时间内重选小区数量超过阈值NCR_H时为高速移动状态。当UE在规定时间内重选小区数量超过阈值NCR_M时为中速移动状态。
对于不同优先级的异频小区重选，按照网络配置的优先级顺序，当高优先级频率小区的S值(例如Squal或Srxlev)大于网络配置的门限值，且持续时间超过网络配置的时间门限值，则UE重选到该高优先级频率小区。
下面结合附图介绍本公开的实施例。本公开实施例提供的驻留的方法和设备可以应用于无线通信系统中。该无线通信系统可以为5G系统，参考图2，为本公开实施例提供的一种无线通信系统的架构示意图。如图2所示，该无线通信系统可以包括：网络侧设备20和用户设备，例如用户设备记做UE 21，UE 21可以与网络侧设备20通信。在实际应用中上述各个设备之间的连接可 以为无线连接，为了方便直观地表示各个设备之间的连接关系，图2中采用实线示意。
需要说明的是，上述通信系统可以包括多个UE，网络侧设备和可以与多个UE通信(传输信令或传输数据)。
本公开实施例提供的网络侧设备可以为基站，该网络侧设备可以为通常所用的基站，也可以为演进型基站(evolved node base station，eNB)，还可以为5G系统中的网络侧设备(例如下一代基站(next generation node base station，gNB)或发送和接收点(Transmission And Reception Point，TRP))等设备。
本公开实施例提供的用户设备可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(Personal Digital Assistant，PDA)等。
参见图3，图中示出了本公开实施例的驻留的方法的流程，该方法的执行主体为UE，具体步骤如下：
步骤301、接收选择或重选配置信息，其中，所述选择或重选配置信息指示出带宽部分BWP或波束beam的位置；
在本公开实施例中，可选地，选择或重选配置信息可以包括以下一项或多项的任意组合：BWP或beam的选择配置信息；以及，BWP或beam的重选配置信息。
其中，可选地，BWP或beam的选择配置信息可以包括以下一项或多项的任意组合：一个或多个偏移量；最小接收信号强度要求；最小接收信号质量要求；补偿量；参考信号类型(例如SSB(同步信息块)或CSI-RS(道状态信息参考信号))；子载波间隔(Subcarrier Spacing，SCS)；以及，BWP标识信息或beam标识信息。
以BWP的选择配置信息为例：偏移量可以是Qoffset temp(BWP_i)，和/或Q rxlevminoffset(BWP_i)，和/或Q qualminoffset(BWP_i))；最小接收信号强度要求可以是Q rxlevmin(BWP_i)；最小接收信号质量要求可以是Q qualmin(BWP_i)；补偿量可以是P compensation(BWP_i)。需要说明的是，beam的选择配置信息与此类似，在此不再敷述。

在本公开实施例中，可以通过方式一和方式二实现在对应UE可驻留的BWP或beam进行驻留：
方式一、根据BWP或beam的选择配置信息，选择所述UE可驻留的一个或多个BWP或beam进行驻留。
在本公开实施例中，选择所述UE可驻留的一个或多个BWP或beam进行驻留中的选择顺序为以下任意顺序或任意一项：选择可驻留的小区或频点；选择可驻留的BWP；以及，选择可驻留的beam。
在本公开实施例中，选择所述UE可驻留的一个或多个BWP或beam进行驻留的方式可以是如下任意一种：

方式c、当允许选择大于一个驻留的BWP或beam时，根据所述选择配置信息，选择满足第一准则的多个所述UE可驻留的BWP或beam进行驻留。当已经选择的一个或多个BWP或beam中有一个或多个BWP或beam不满足第一准则，根据所述选择配置信息，不选择不满足所述第一准则的BWP或beam进行驻留；当已经在选择满足第一准则的一个或多个BWP或beam进行驻留后，其他所述UE可驻留的BWP或beam满足所述第一准则，根据所述选择配置信息，选择增加满足所述第一准则的其他所述UE可驻留的BWP或beam进行驻留。
需要说明的是，上述第一准则可以为：BWP或beam的测量结果大于配 置的门限值，在本公开实施例中对于配置的门限值并不做具体限定。
例如：选择UE可驻留的BWP时，第一准则为：Srxlex(BWP_i)>0和/或Squal(BWP_i)>0，其中：
Srxlex(BWP_i)＝Q rxlevmeas(BWP_i)–(Q rxlevmin(BWP_i)+Q rxlevminoffset(BWP_i))–P compensation(BWP_i)–Qoffset temp(BWP_i)；
Squal(BWP_i)＝Q qualmeas(BWP_i)–(Q qualmin(BWP_i)+Q qualminoffset(BWP_i))–Qoffset temp(BWP_i)；
其中，Srxlex(BWP_i)表示：BWP选择接收信号强度，单位dB；

例如：选择驻留的beam时，第一准则为：Srxlex(beam_i)>0和/或Squal(beam_i)>0，其中：
Srxlex(beam_i)＝Q rxlevmeas(beam_i)–(Q rxlevmin(beam_i)+Q rxlevminoffset(beam_i))–P compensation(beam_i)–Qoffset temp(beam_i)；
Squal(beam_i)＝Q qualmeas(beam_i)–(Q qualmin(beam_i)+Q qualminoffset(beam_i))–Qoffset temp(beam_i)；
其中，Srxlex(beam_i)表示：beam选择接收信号强度，单位dB；
Squal(beam_i)表示：beam选择接收信号质量，单位dB；

方式二、根据BWP或beam的重选配置信息，重选所述UE可驻留的一个或多个BWP或beam进行驻留。
其中，重选所述UE可驻留的BWP或beam进行驻留中的重选顺序为以下任意顺序或任意一项：重选可驻留的小区或频点；重选可驻留的一个或多个BWP；以及，重选可驻留的一个或多个beam。
在本公开实施例中，在重选所述UE可驻留的一个或多个BWP或beam进行驻留时，可以根据异频重选的条件，判断是同频重选所述UE可驻留的BWP或beam进行驻留还是异频重选所述UE可驻留的BWP或beam进行驻留；若满足所述异频重选的条件，根据所述重选配置信息，异频重选所述UE可驻留的BWP或beam进行驻留；否则，根据所述重选配置信息，同频重选所述UE可驻留的BWP或beam进行驻留；
进一步地，异频重选的条件包括以下一项或多项的任意组合：当前驻留的服务频点和目标频点不同；当前驻留的服务频点和目标频点的带宽不同；当前驻留的服务频点和目标频点的子载波间隔不同；以及，当前驻留的服务频点和目标频点的参考信号类型不同，例如：当前服务频点的测量的RS类型为SSB，目标频点的测量的参考信号类型为CSI-RS。
在本公开实施例中，可以通过以下任意一种方式重选所述UE可驻留的一个或多个BWP或beam进行驻留：
方式a、当只允许重选一个驻留的BWP或beam时，根据重选配置信息，重选满足第二准则的任意一个所述UE可驻留的BWP或beam进行驻留；
方式b、当只允许重选一个驻留的BWP或beam时，根据重选配置信息，在满足第二准则的BWP或beam中重选信号质量最好或重选信号强度最好的一个所述UE可驻留的BWP或beam进行驻留；
方式c、当允许重选大于一个驻留的BWP或beam时，根据重选配置信息，重选满足第二准则的多个所述UE可驻留的BWP或beam进行驻留。
其中，第二准则可以为：根据配置的BWP或beam的优先级，重选所述UE可驻留的BWP或beam。
示例：判断是否是“同优先级重选”还是“不同优先级重选”，从而重选所述UE可驻留的BWP或beam。
对于“不同优先级重选”，按照网络配置的优先级顺序，当高优先级BWP或Beam的S值大于配置的门限值，且持续时间超过配置的时间门限值，则UE重选到该高优先级BWP或Beam。
以不同优先级重选BWP为例，高优先级BWP的S值为Squal(BWP_i)和/或Srxlev(BWP_i))；门限值为TreselectionRAT(BWP_i)；时间门限值为ThreshX,HighQ(BWP_i)和/或ThreshX，HighP(BWP_i))。不同优先级重选beam与此类似，在此不再敷述。
对于“同优先级重选”，R s用于表示服务BWP或Beam的信号质量，R n用于表示邻BWP或Beam的信号质量。UE重选的BWP或Beam为到信号质量最好(即R s和R n中的最大值)的BWP或Beam，或信号质量超过信号质量门限值的BWP或Beam。满足该准则的BWP或Beam的测量结果的持续时间大于或等于配置的时间门限值。
以同优先级重选BWP为例，信号质量门限值为ThreshX,HighQ(BWP_i)和/或ThreshX,HighP(BWP_i)；时间门限值为TreselectionRAT(BWP_i)。
R s(BWP_i)＝Q meas,s(BWP_i)+Q Hyst(BWP_i)–Qoffset temp(BWP_i)；
R n(BWP_i)＝Q meas,n(BWP_i)–Q offset(BWP_i)–Qoffset temp(BWP_i)；
其中：
Q meas(BWP_i)表示BWP_i重选过程中用的RSRP/RSRQ测量量；
Q offset(BWP_i)表示BWP_i偏移量；
Qoffset temp(BWP_i)表示BWP_i的临时偏移量；
Q Hyst(BWP_i)表示BWP_i的基于速度的缩放因子，在高速移动状态时取值为sf-High，在中速移动状态时取值为sf-Medium。其他状态，不采用该因子，即为“0”。
以同优先级重选beam为例，信号质量门限值为ThreshX,HighQ(beam_i)和/或ThreshX,HighP(beam_i)；时间门限值为TreselectionRAT(beam_i)。 其中，
R s(beam_i)＝Q meas,s(beam_i)+Q Hyst(beam_i)–Qoffset temp(beam_i)；
R n(beam_i)＝Q meas,n(beam_i)–Q offset(beam_i)–Qoffset temp(beam_i)；
其中：
Q meas(beam_i)表示beam_i重选过程中用的RSRP/RSRQ测量量；
Q offset(beam_i)表示beam_i偏移量；
Qoffset temp(beam_i)表示beam_i的临时偏移量；
Q Hyst(beam_i)表示beam_i的基于速度的缩放因子，在高速移动状态时取值为sf-High，在中速移动状态时取值为sf-Medium。其他状态，不采用该因子，即为“0”。
这样，能够实现将IDLE或INACTIVE状态的UE分配到不同的BWP或Beam上进行驻留，避免由于UE在任意BWP或beam驻留，导致某一个BWP或beam拥塞的问题，从而可以起到负载均衡的作用。
参见图4，图中示出了本公开实施例的驻留的方法的流程，该方法的执行主体为UE，具体步骤如下：
