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202010759801.1、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
本发明涉及通讯技术领域，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，不同业务的UE可能需要在特定的载波上进行寻呼的监听，则现有的寻呼载波确定机制显然无法按业务确定寻呼载波，影响NB-IOT系统的工作效率。

可选的，多个载波组中至少一部分载波组对应的寻呼参数不同于其他载波组对应的寻呼参数。
可选的，所述寻呼方法还包括：基于小区级别寻呼配置确定所述优选载波组中各载波的寻呼权重。

与现有技术相比，本发明实施例的技术方案具有以下有益效果：

较之现有基站仅在根据UE标识确定的唯一的寻呼载波内发送寻呼消息的技术方案，采用本实施例方案的基站能够根据UE当前业务确定合适的优选载波组，进而在优选载波组内选定寻呼载波发送寻呼消息。由此，使得实现载波级别寻呼配置下的寻呼成为可能。

图6是本发明实施例一种寻呼装置的结构示意图。
具体实施方式
如背景技术所言，目前的寻呼载波确定机制无法实现不同业务 UE在不同寻呼配置载波上进行寻呼监听。
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 Bandwidth Secondary 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不同业务UE在不同寻呼配置载波上进行寻呼监听。
为解决上述技术问题，本发明实施例提供一种寻呼载波的确定方法，包括：根据当前业务确定优选载波组，其中，载波组和业务一一对应，每一载波组对应地配置有寻呼参数；根据UE标识、所述优选载波组中各载波的寻呼权重以及所述优选载波组对应的寻呼参数，从所述优选载波组中选定所述寻呼载波。
本发明方案能够根据业务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，通过预先根据业务配置多个具有不同寻呼配置的载波组，UE可以根据业务确定本次应哪个载波组内选择载波进行寻呼监听，确定的载波组即为所述优选载波组。进一步，UE确定优选载波组后，可以根据UE标识、优选载波组内各载波的寻呼权重以及相关的广播参数在所述优选载波组内唯一确定寻呼载波。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明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，根据当前业务确定优选载波组，其中，载波组和业务一一对应，每一载波组对应地配置有寻呼参数；
步骤S102，根据UE标识、所述优选载波组中各载波的寻呼权重以及所述优选载波组对应的寻呼参数，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，网络可以根据业务配置不同的载波组，这些 不同的载波组可以根据业务的特点配置不同的寻呼参数配置。例如，不同业务对应的载波组的寻呼周期、单个DRX周期内包括的寻呼帧的数量N、单个寻呼帧包括的寻呼时机的数量N s和/或PDCCH重复次数等寻呼参数可以是不相同的。
具体地，载波组和业务之间的一一对应的关系可以由网络预先配置给UE。例如，可以通过系统消息等将寻呼配置信息预先配置给UE。
在所述步骤S101中，可以将需要传输的数据所属的业务对应的载波组确定为所述优选载波组，进而在所述优选载波组内选择载波进行寻呼的监听。
进一步，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，对于UE当前所处小区的多个载波组，所述多个载波组中至少一部分载波组对应的寻呼参数可以不同于其他载波组对应的寻呼参数。也即，多个载波组中部分载波组对应相同的寻呼参数，另一部分载波组对应不同的寻呼参数。
其中，对应不同的寻呼参数可以指，不同业务对应的载波组对应的寻呼参数完全不同，或者部分相同部分不同。
在一个具体实施中，所述优选载波组中各载波的寻呼权重可以为基于小区级别寻呼配置确定的寻呼权重。
具体而言，小区内所有载波的载波权重是按照现有协议版本(即Release 16(简称R16)协议版本)配置的。也即，每个载波对应一个固定的寻呼权重，且每个载波的寻呼权重是按照现有R16协议配置的。
假设小区有K个载波，则W(0),W(1),…,W(K-1)为各个载波的寻呼权重。例如，参考图2，假设k＝8且8个载波分别属于3个载波组对应3种不同业务，其中，载波组1对应业务1，包括载波1和载波2；载波组2对应业务2，包括载波3至载波6；载波组3对应业务3， 包括载波7和载波8。进一步，载波1的寻呼权重沿用现有协议为载波1配置的寻呼权重W(0)，载波2的寻呼权重沿用现有R16协议版本为载波2配置的寻呼权重W(1)，...，以此类推，载波8的寻呼权重沿用现有R16协议版本为载波8配置的寻呼权重W(7)。
在一个具体实施中，各载波组之间不存在载波重叠。也即，小区内所有载波被预先按业务划分为多个载波组，且每个载波仅属于某一个载波组。
例如，继续参考图2，业务1对应的载波组1、业务2对应的载波组2和业务3对应的载波组3相互之间没有载波重叠。
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对应特定业务的载波组，不论这一个或多个载波是否相邻。例如，图2示出的载波1、载波3可能属于载波组1，而载波2、载波4至载波6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，所述步骤S102可以包括步骤：根据UE标识、所述优选载波组中各载波的寻呼权重以及所述优选载波组对应的寻呼参数计算比较值；自所述优选载波组中索引号最小的载波开始，逐个累加所述优选载波组中各载波的寻呼权重，当累加值大于所述比较值时，将最后一个累加的载波确定为所述寻呼载波。
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为所述优选载波组中各载波的寻呼权重之和；modW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。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，当确定的优选载波组为图2示出的载波组2，则W＝W(2)+W(3)+W(4)+W(5)。进一步，在所述步骤S102中，在计算得到所述比较值X后，可以自索引号(index)为2的载波3开始，逐个累加载波组2中各载波的寻呼权重。假设累加到载波5时累加值大于比较值X，则可以确定载波5为所述寻呼载波。
在一个具体实施中，寻呼消息仅在所述寻呼载波上发送。也即，网络仅在所述寻呼载波上发送对UE的寻呼消息，相应的，UE仅监听所述寻呼载波以接收网络发送的寻呼消息。
在本实施例的一个变化例中，所述优选载波组中各载波的寻呼权重可以为基于载波组级别寻呼配置确定的寻呼权重。也即，对于小区中的每个载波组，网络会单独配置相关的寻呼参数，如载波组内载波的寻呼权重、单个DRX周期内包括的寻呼帧的数量N和/或单个寻呼帧包括的寻呼时机的数量N s等。本变化例较之上述实施例的方案灵活度更高。
具体而言，小区内所有载波按照现有协议配置了寻呼权重，即每个载波对应一个现有协议配置的寻呼权重。假设小区有K个载波，则W(0),W(1),…,W(K-1)为各个载波按现有协议配置的寻呼权重。
进一步，为实现不同业务的UE在不同的载波组内选择载波进行寻呼的监听，网络可以根据业务配置不同的载波组(或载波列表)，并对于特定业务的载波组内的载波额外配置一个寻呼权重。
也就是说，在本变化例中，一个载波可能对应两个寻呼权重，其中一个是针对现有终端的寻呼权重，其中另一个是针对未来NB-IOT终端的寻呼权重。其中，未来NB-IOT终端是指支持载波级别的寻呼参数配置的终端。
例如，参考图3，假设k＝8且8个载波分别属于2个载波组对应2种不同业务，其中，载波组1对应业务1，包括载波1至载波5；载波组2对应业务2，包括载波6至载波8。
进一步，每个载波各自对应两个寻呼权重。W(i-1)为沿用现有协议为第i个载波配置的寻呼权重，1≤i≤8；A(j-1)为网络针对业务1为载波组1中的第j个载波配置的寻呼权重，1≤j≤5；B(k-1)为网络针对业务2为载波组2中的第k个载波配置的寻呼权重，6≤k≤8。
假设UE的当前业务为业务1，则优选载波组为图3中的载波组1，相应的，W＝A(0)+A(1)+A(2)+A(3)+A(4)。进一步，载波组1可以对应有专门配置的单个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。
由上，采用本实施例方案，能够根据业务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，通过预先根据业务配置多个具有不同寻呼配置的载波组，UE可以根据业务确定本次应哪个载波组内选择载波进行寻呼监听，确定的载波组即为所述优选载波组。进一步，UE确定优选载波组后，可以根据UE标识、优选载波组内各载波的寻呼权重以及相关的广播参数在所述优选载波组内唯一确定寻呼载波。
进一步，载波组与业务一一对应，不同载波组的寻呼参数配置可以不相同，各载波的寻呼权重可沿用现有配置也可额外配置，各载波组之间没有载波重叠。
进一步，对于UE侧和网络侧，均仅在确定的唯一载波(即所述寻呼载波)上发送或接收寻呼。
图4是本发明实施例一种寻呼载波的确定装置的结构示意图。本领域技术人员理解，本实施例所述寻呼载波的确定装置4可以用于实施上述图1至图3所述实施例中所述的方法技术方案。
具体地，参考图4，本实施例所述寻呼载波的确定装置4可以包括：确定模块41，用于根据当前业务确定优选载波组，其中，载波组和业务一一对应，每一载波组对应地配置有寻呼参数；选择模块42，用于根据UE标识、所述优选载波组中各载波的寻呼权重以及所述优选载波组对应的寻呼参数，从所述优选载波组中选定所述寻呼载波。
关于所述寻呼载波的确定装置4的工作原理、工作方式的更多内容，可以参照上述图1至图3中的相关描述，这里不再赘述。
在具体实施中，上述的寻呼载波的确定装置4可以对应于用户设备中具有寻呼功能的芯片，或者对应于具有数据处理功能的芯片，例如片上系统(System-On-a-Chip，简称SOC)、基带芯片等；或者对应于用户设备中包括具有寻呼功能芯片的芯片模组；或者对应于具有数据处理功能芯片的芯片模组，或者对应于用户设备。
图5是本发明实施例一种寻呼方法的流程图。
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网络侧执行，如由网络侧的基站执行。具体而言，执行本实施例所述方案的基站可以是配合未来能够实现载波级别寻呼配置的UE进行寻呼的。
在具体实施中，下述步骤S501～步骤S503所提供的寻呼方法可以由网络设备中的具有寻呼功能的芯片执行，也可以由网络设备中的基带芯片执行。
具体地，参考图5，本实施例所述寻呼方法可以包括如下步骤：
步骤S501，发送寻呼配置信息，其中，所述寻呼配置信息包括业务和载波组的一一对应关系，还包括每一载波组对应的寻呼参数；
步骤S502，根据UE的当前业务确定优选载波组；
步骤S503，根据UE标识、所述优选载波组中各载波的寻呼权重以及所述优选载波组对应的寻呼参数，从所述优选载波组中选定所述寻呼载波，并在所述寻呼载波上寻呼所述UE。
本领域技术人员理解，所述步骤S501至步骤S503可以视为与上述图1所示实施例所述步骤S101至步骤S102相呼应的执行步骤，两者在具体的实现原理和逻辑上是相辅相成的。因而，本实施例中涉及名词的解释可以参考图1所示实施例的相关描述，这里不再赘述。
具体而言，步骤S501可以是在UE接入小区后的任意时刻执行的。例如，基站可以通过广播的方式向接入的UE发送所述寻呼配置信息。
进一步，步骤S502和步骤S503可以是在基站需要寻呼UE时执行的。
进一步，UE的当前业务可以理解为是基站的已知量。例如，UE在初始接入小区后就可以告知基站自己所要进行的业务。
在一个具体实施中，多个载波组中至少一部分载波组对应的寻呼参数不同于其他载波组对应的寻呼参数。
在一个具体实施中，本实施例所述寻呼方法还可以包括：基于小区级别寻呼配置确定所述优选载波组中各载波的寻呼权重。例如，可以按照现有协议为各载波配置寻呼权重，并通过所述寻呼配置信息发送至UE。配置得到的寻呼权重可以参考图2中的具体示例。
在一个变化例中，本实施例所述寻呼方法还可以包括：基于载波组级别寻呼配置确定所述优选载波组中各载波的寻呼权重。例如，可以按照未来终端所支持的载波级别寻呼配置来额外配置各个载波的 寻呼权重，并通过所述寻呼配置信息发送至UE。配置得到的寻呼权重可以参考图3中的具体示例。
在一个具体实施中，各载波组之间不存在载波重叠。
在一个具体实施中，所述步骤S503可以包括步骤：根据UE标识、所述优选载波组中各载波的寻呼权重以及所述优选载波组对应的寻呼参数计算比较值；自所述优选载波组中索引号最小的载波开始，逐个累加所述优选载波组中各载波的寻呼权重，当累加值大于所述比较值时，将最后一个累加的载波确定为所述寻呼载波。
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为所述优选载波组中各载波的寻呼权重之和；mod为取模运算。
由上，采用本实施例方案的基站能够根据UE当前业务确定合适的优选载波组，进而在优选载波组内选定寻呼载波发送寻呼消息。由此，使得实现载波级别寻呼配置下的寻呼成为可能。
图6是本发明实施例一种寻呼装置的结构示意图。本领域技术人员理解，本实施例所述寻呼装置6可以用于实施上述图5所述实施例中所述的方法技术方案。
