Description

寻呼载波的确定及寻呼方法、装置、存储介质、终端、基站
本申请要求2020年7月31日提交中国专利局、申请号为202010762397.3、发明名称为“寻呼载波的确定及寻呼方法、装置、存储介质、终端、基站”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及通讯技术领域，具体地涉及一种寻呼载波的确定及寻呼方法、装置、存储介质、终端、基站。
背景技术
在目前的协议中，窄带物联网(Narrow Band Internet of Things，简称NB-IoT)终端根据用户设备标识(User Equipment Identification，简称UE_ID)以及网络广播的参数，结合特定的公式可以唯一确定一个载波用于寻呼(paging)的监听。而在未来，NB-IOT会引入载波级别的寻呼参数配置，也即不同载波会具有不同的寻呼参数配置。
由于现有的寻呼载波确定机制是基于UE标识唯一确定的，也即一个UE基于自身的UE标识只能唯一地对应一个寻呼载波。这样的寻呼载波确定机制显然无法适应未来载波级别的寻呼参数配置。例如，在未来，UE可能需要根据自身的状态与所处环境来选择一个特定寻呼配置的载波进行寻呼的监听。则现有的寻呼载波确定机制显然无法满足UE根据自身实际情况来选择寻呼载波，影响NB-IOT系统的工作效率。

具体实施方式
由于NB-IoT单频点小区只有180千赫兹(kHz)的带宽，该带宽上除了用于窄带物联网的主同步信号(Narrow Bandwidth Primary Synchronization Signal，简称NPSS)、用于窄带物联网的辅同步信号(Narrow BandwidthSecondary Synchronization Signal，简称NSSS)以及系统信息块(System Information Block，简称SIB)的开销外，剩余业务信道容量很小。
为了支持海量终端，需要采用多个频点来提高网络容量。小区内除了包含NPSS、NSSS和用于窄带物联网的物理广播信道(Narrow Bandwidth Physical Broadcast Channel，简称NPBCH)的锚点载波(anchor carrier)之外，还可以包含若干个不包含NPSS、NSSS和NPBCH的非锚点载波(non-anchor carrier)。
也就是说，一个小区可以包括一个锚点载波和若干个非锚点载波，其中每个载波的频谱带宽为180kHz，小区内所有载波的最大频谱跨度不超过20兆赫兹(MHz)。
其中，所述锚点载波是指，多载波小区中有且只有一个下行载波，所述锚点载波支持同时承载NPSS、NSSS、NPBCH、用于窄带物联网的物理下行控制信道(Narrow Bandwidth Physical Downlink Control  Channel，简称NPDCCH)以及用于窄带物联网的物理下行共享信道(Narrow Bandwidth Physical Downlink Shared Channel，简称NPDSCH)，该载波即为所述锚点载波。UE在锚点载波需要监控NPSS、NSSS，以及在NPBCH、NPDCCH和NPDSCH上传输的信息。
进一步，多载波小区中可以有若干个只承载NPDCCH和NPDSCH，但不承载NPSS、NSSS和NPBCH的下行载波，称为非锚点载波。UE可以在非锚点载波上进行数据传输。
此外，在UE进入连接态前，网络会通过随机接入过程中的消息4(Msg4)指定一个载波用于后续的下行数据传输。UE在空闲(idle)态下可以在非锚点载波上进行寻呼的监听。
在现有的协议中，网络通过系统信息下发有关寻呼的参数配置信息，包括寻呼的周期、寻呼时机(Paging occasion，简称PO)对应的PDCCH重复次数、每个非连续接收(Discontinuous Reception，简称DRX)周期(cycle)内包含的寻呼帧(Paging Frame，简称PF)的数量N以及每个寻呼帧包含的寻呼时机的数量N s等参数。
根据现有协议的规定，上述这些寻呼配置信息中配置的参数是小区级别的，也即，小区内所有载波的寻呼参数配置都是一致的。此外，网络还会配置每个载波(包括锚点载波与非锚点载波)的寻呼权重。
UE在空闲态的时候，可以根据UE标识(UE_ID)、参数N与N s以及每个载波的寻呼权重，结合公式floor(UE_ID/(N×N s))mod W<W(0)+W(1)+…+W(n)确定在哪个载波上进行寻呼的监听。其中，W为小区内所有载波的寻呼权重之和，W(0)为索引号为0的载波对应的寻呼权重，以此类推。满足上述公式的最小索引号n对应的载波即为接收寻呼的载波。
每个UE可以根据自己的UE标识以及网络配置的参数唯一地确定一个寻呼载波。
为了保证覆盖范围，NB-IOT采用了重复传输的技术。对于下行 传输最大的重复次数是2048次，对于上行传输，最大的重复次数为128次。
目前的寻呼载波确定机制无法实现UE根据自身实际情况来选择寻呼载波进行寻呼监听。
为解决上述技术问题，本公开实施例提供一种寻呼载波的确定方法，包括：根据UE标识、载波组的寻呼权重以及公共寻呼参数确定优选载波组，其中，所述公共寻呼参数对应所有载波组，每一载波组对应配置有寻呼权重；至少根据当前所处覆盖等级和/或测量得到的信道质量，从所述优选载波组中选定所述寻呼载波。
本公开方案能够根据UE自身状态和所处环境选择合适的寻呼参数配置对应的载波进行寻呼监听，利于提高NB-IOT系统的工作效率。具体而言，通过预先配置多个载波组并为每一载波组配置对应的寻呼权重，UE可以根据UE标识、载波组的寻呼权重以及相关的广播参数(如公共寻呼参数)唯一确定一个载波组，确定的载波组即为所述优选载波组。进一步，UE在确定优选载波组后，可以根据自身实际情况在优选载波组内选择一个较为合适的载波作为寻呼载波，并在该寻呼载波上进行寻呼的监听。
为使本公开的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本公开的具体实施例做详细的说明。
图1是本公开实施例一种寻呼载波的确定方法的流程图。
本实施方案可以应用于5G系统，如应用于NB-IOT中实现载波级别的寻呼配置场景。
本实施例方案可以由用户设备侧执行，如由用户设备侧的UE执行。具体而言，执行本实施例所述方案的UE可以是未来能够实现载波级别寻呼配置的UE。
在具体实施中，下述步骤S101～步骤S102提供的寻呼载波的确定方法可以由用户设备中的具有寻呼功能的芯片执行，也可以由用户 设备中的基带芯片执行。
具体地，参考图1，本实施例所述寻呼载波的确定方法可以包括如下步骤：
步骤S101，根据UE标识、载波组的寻呼权重以及公共寻呼参数确定优选载波组，其中，所述公共寻呼参数对应所有载波组，每一载波组对应配置有寻呼权重；
步骤S102，至少根据当前所处覆盖等级和/或测量得到的信道质量，从所述优选载波组中选定所述寻呼载波。
在一个具体实施中，网络可以配置多个载波组，各个载波组是完全等价的。也就是说，每一载波组各自包括的载波的数量均相同，且各载波组间的寻呼参数配置保持一致。
具体而言，各载波组间的寻呼参数配置保持一致是指，各个载波组具有相同的非公共寻呼参数，这些非公共寻呼参数根据需要分配给各载波组内的特定载波。
进一步，非公共寻呼参数可以基于载波级别的寻呼参数配置确定。
例如，参考图2，网络共配置4个载波组，对应图中载波组0、载波组1、载波组2和载波组3，其中每一载波组内存在3个载波，且3个载波分别对应的非公共寻呼参数配置为G1、G2和G3。对应图2，各载波组间的寻呼参数配置保持一致是指，4个载波组均有G1、G2和G3这三种非公共寻呼参数的配置。
在一个具体实施中，对于每一载波组，所述载波组包括的多个载波中至少一部分载波对应的非公共寻呼参数，可以不同于同一载波组中其他载波对应的非公共寻呼参数。也就是说，单个载波组内的载波可以有不同的非公共寻呼参数配置。
其中，不同的非公共寻呼参数配置可以指，载波组内的各载波对 应的非公共寻呼参数完全不同，或者部分相同部分不同。
例如，对于单个载波组而言，所述载波组内的多个载波可以对应不同的寻呼周期、不同的单个DRX周期内包括的寻呼帧的数量N、不同的单个寻呼帧包括的寻呼时机的数量N s或者不同的PDCCH重复次数等。
例如，继续参考图2，载波组0包括的三个载波分别对应非公共寻呼参数配置G1、G2和G3，且G1、G2和G3的一个或多个寻呼参数的具体数值不同。
在一个具体实施中，网络可以为每一载波组配置一个寻呼权重。
例如，参考图2，载波组0对应寻呼权重D(0)、载波组1对应寻呼权重D(1)、载波组2对应寻呼权重D(2)、载波组3对应寻呼权重D(3)。各载波组内的载波不再额外配置寻呼权重。
在一个具体实施中，网络可以为所有载波组配置部分公共寻呼参数，用于确定寻呼特定UE的优选载波组。具体而言，所述公共寻呼参数对应小区的所有载波组。换言之，所有载波组可以共用所述公共寻呼参数配置，而各载波组内的载波可以对应不同的非公共寻呼参数。
其中，所述公共寻呼参数用于供网络和UE确定优选载波组，而载波组内各载波分别配置的非公共寻呼参数则供UE在选定该载波作为寻呼载波后实际执行寻呼的监听。
例如，所述公共寻呼参数可以包括单个DRX周期内包括的寻呼帧的数量N，还可以包括单个寻呼帧包括的寻呼时机的数量N s。
又例如，非公共寻呼参数可以包括寻呼周期、PDCCH重复次数等。
在一个具体实施中，多个载波组中至少一部分载波组之间可以存在载波重叠。也就是说，不同载波组中可以存在相同的载波。
例如，参考图2，载波组0可以包括载波1、载波2和载波3，载波组1可以包括载波2、载波3和载波4，载波组2可以包括载波5、载波6和载波7，载波组3可以包括载波6、载波7和载波8。
进一步，对于在多个载波组之间重叠的载波，所述载波在不同载波组中对应的非公共寻呼参数可以不相同。
例如，参考图2，载波2在载波组0中对应寻呼参数配置G2，而在载波组1中对应非公共寻呼参数配置G1。
又例如，参考图2，载波3在载波组0中对应寻呼参数配置G3，而在载波组1中对应非公共寻呼参数配置G2。
又例如，参考图2，载波6在载波组2中对应寻呼参数配置G2，而在载波组3中对应非公共寻呼参数配置G1。
又例如，参考图2，载波7在载波组2中对应寻呼参数配置G3，而在载波组3中对应非公共寻呼参数配置G2。
在一个变化例中，各载波组之间可以不存在载波重叠。也即，小区内所有载波被预先划分为多个载波组，且每个载波仅属于某一个载波组。
例如，参考图3，假设网络将小区内的8个载波分配为4个载波组，其中载波组0包括载波1和载波2，载波组0对应寻呼权重D(0)，载波1对应非公共寻呼参数配置G1，载波2对应非公共寻呼参数配置G2；载波组1包括载波3和载波4，载波组1对应寻呼权重D(1)，载波3对应非公共寻呼参数配置G1，载波4对应非公共寻呼参数配置G2；载波组2包括载波5和载波6，载波组2对应寻呼权重D(2)，载波5对应非公共寻呼参数配置G1，载波6对应非公共寻呼参数配置G2；载波组3包括载波7和载波8，载波组3对应寻呼权重D(3)，载波7对应非公共寻呼参数配置G1，载波8对应非公共寻呼参数配置G2。
在一个具体实施中，载波组的划分可以是按照载波的索引号按顺 序划分的，如相邻的一个或多个载波属于同一载波组。
或者，网络可以根据小区的实际情况，任意选择更为合适的一个或多个载波组成一个载波组，不论这一个或多个载波是否相邻。例如，图2示出的载波1和载波3可能属于载波组1，而载波2和载波4则属于载波组2。
在一个具体实施中，UE标识可以用于唯一地标识UE，如所述UE标识可以为国际移动用户识别码(International Mobile Subscriber Identity，简称IMSI)，还可以为临时移动用户标识(Serving-Temporary Mobile Subscriber Identity，简称S-TMSI)。
在一个具体实施中，本申请中的载波组可以等效为现有技术中的载波，在本申请实施例中，以载波组为单位配置寻呼权重，网络根据UE标识、各个载波组的寻呼权重以及公共寻呼参数确定优选载波组，并在该优选载波组内的所有载波上寻呼UE。
具体而言，网络可以预先配置载波组列表，所述载波组列表包括载波组的索引(index)以及各载波组包括的载波。所述载波组列表可以包含于寻呼配置信息中发送至UE，以便UE执行步骤S101时从中选择优选载波组。
进一步，所述载波组列表还可以包括各载波组对应的寻呼权重。或者，各载波组对应的寻呼权重可以在寻呼配置信息中单独指示，如与载波组的索引一一对应的指示。
进一步，所述载波组列表还可以包括载波组中各载波的非公共寻呼参数。或者，各载波的非公共寻呼参数可以在寻呼配置信息中单独指示，如与载波组的索引以及该载波组内各载波的索引一一对应的指示。
在一个具体实施中，本实施例所述确定方法还可以包括步骤：接收寻呼配置信息，其中，所述寻呼配置信息包括所述公共寻呼参数以及每一载波组对应的寻呼权重。由此，UE可以确定优选载波组。
具体地，寻呼配置信息可以通过广播发送。
进一步，接收所述寻呼配置信息的操作可以是在UE接入小区后的任意时刻执行的。
进一步，寻呼配置信息可以通过系统消息承载。
本实施例所述的载波组也可以理解为载波列表，即由至少一个载波组成的集合。
在一个具体实施中，寻呼配置信息还可以包括每一载波对应的信道质量阈值和/或覆盖等级。相应的，UE可以根据优选载波组中各载波各自对应的信号质量阈值，和/或覆盖等级进行选择，以从中选出与自身实际情况相符的载波作为寻呼载波。
例如，所述信道质量阈值可以包括参考信号接收功率(Reference Signal Received Power，简称RSRP)阈值。
又例如，所述信道质量阈值可以包括参考信号接收质量(Reference Signal Received Quality，简称RSRQ)阈值。
在一个具体实施中，所述步骤101可以包括步骤：根据UE标识、载波组的寻呼权重以及公共寻呼参数计算比较值；自多个载波组中索引号最小的载波组开始，逐个累加各载波组的寻呼权重，当累加值大于所述比较值时，将最后一个累加的寻呼权重对应的载波组确定为所述优选载波组。
具体地，可以基于如下公式计算得到所述比较值：
X＝floor(UE_ID/(N×N S))modW；
其中，X为所述比较值；floor()函数为向下取整函数；UE_ID为所述UE标识；N为单个DRX周期内包括的寻呼帧的数量；N s为单个寻呼帧包括的寻呼时机的数量；W为所述多个载波组各自的寻呼权重之和；mod为取模运算。
进一步，N和N s可以为网络预先通过广播等方式指示给UE的公共寻呼参数。如网络可以预先通过寻呼配置信息配置所述单个DRX周期内包括的寻呼帧的数量N和单个寻呼帧包括的寻呼时机的数量N s。
例如，参考图2，W＝D(0)+D(1)+D(2)+D(3)。进一步，在所述步骤S101中，在计算得到比较值X后，可以自索引号(index)为0的载波组0开始，逐个累加各个载波组的寻呼权重。假设累加到载波组2时累加值大于比较值X，则可以确定载波组2为所述优选载波组。
在一个具体实施中，寻呼消息可以在所述优选载波组内的所有载波上发送。相应的，在所述步骤S102之后，本实施例所述确定方法还可以包括步骤：在选定的所述寻呼载波上接收所述寻呼消息。
也即，网络在优选载波组内的所有载波上寻呼UE，而UE则根据自身当前所处环境以及状态等实时地从优选载波组中选择一个较为合适的寻呼载波接收所述寻呼消息。
例如，在步骤S101确定的优选载波组内，UE可以根据自身所处环境或者接收信号质量，如当前所处的覆盖等级或者实际测量得到的参考信号接收功率(Reference Signal Received Power，简称RSRP)，选择一个合适的载波进行寻呼的监听。也即，UE可以从优选载波组中选择在一个寻呼参数配置适合UE目前状况的载波监听寻呼消息。
在一个具体实施中，所述步骤S102可以包括步骤：测量信道质量，并将所述优选载波组内信道质量阈值最接近测量得到的所述信道质量的载波确定为所述寻呼载波，其中，载波组内的载波与信道质量阈值一一对应。
具体地，信道质量可以通过RSRP表征，相应的，信道质量阈值为RSRP阈值。
更为具体地，载波组内的载波与信道质量阈值之间的一一对应关系可以由所述寻呼配置信息预先指示。
例如，载波组内的每个载波均对应一个RSRP阈值，该RSRP阈值可以是由网络预先配置并通过广播消息下发的。其中，所述广播消息可以为系统信息块(System Information Block，简称SIB)消息，或者主信息块(Master Information Block，简称MIB)消息。
又例如，还可以通过RSRQ或者信道状态信息来衡量测量得到的信道质量。
进一步，通过执行步骤S101以确定优选载波组后，UE可以根据实际测量的RSRP值与网络配置的优选载波组内各载波各自对应的RSRP阈值进行比较。进而选择优选载波组内与UE实际测量得到的RSRP值最接近的RSRP阈值对应的载波进行寻呼消息的监听。
UE可以选择小区内任一载波进行信道质量的测量。例如，UE可以在小区内的锚点载波进行RSRP的测量。
在一个变化例中，所述步骤S102可以包括步骤：将所述优选载波组中对应的覆盖等级与当前所处覆盖等级相符的载波确定为所述寻呼载波，其中，载波组内的载波与覆盖等级一一对应。
具体地，UE当前所处覆盖等级可以根据测量得到的RSRP确定。
更为具体地，载波组内的载波与覆盖等级之间的一一对应关系可以由所述寻呼配置信息预先指示。
例如，载波组内的每个载波均对应一个覆盖等级(Coverage Level)，该覆盖等级可以是由网络预先配置的并通过广播消息下发的。其中，所述广播消息可以为SIB消息或者MIB消息。
进一步，通过执行步骤S101以确定优选载波组后，UE可以根据自身当前所处的覆盖等级，在优选载波组内选择覆盖等级与之对应的载波进行寻呼消息的监听。
在一个具体实施中，除了当前所处覆盖等级以及信道质量之外，还可以根据UE的移动速度、自身电量或能耗等因素从优选载波组中 选择合适的载波作为寻呼载波。
例如，若UE当前能耗较低，则在优选载波组中选择寻呼周期较大的载波作为寻呼载波进行寻呼监听。
由上，采用本实施方案能够根据UE自身状态和所处环境选择合适的寻呼参数配置对应的载波进行寻呼监听，利于提高NB-IOT系统的工作效率。具体而言，通过预先配置多个载波组并为每一载波组配置对应的寻呼权重，UE可以根据UE标识、载波组的寻呼权重以及相关的广播参数(如公共寻呼参数)唯一确定一个载波组，确定的载波组即为所述优选载波组。进一步，UE在确定优选载波组后，可以根据自身实际情况在优选载波组内选择一个较为合适的载波作为寻呼载波，并在该寻呼载波上进行寻呼的监听。
进一步，各载波组的寻呼参数配置相同，载波组内不同载波的非公共寻呼配置参数不同，一个载波组对应一个寻呼权重，各载波组之间可以有载波重叠。
进一步，网络侧在优选载波组的所有载波上发寻呼，UE侧在选定的优选载波组内的特定载波上监听寻呼。
