Description

一种通信方法及相关设备
本申请要求于2019年8月15日提交中国专利局、申请号为201910755656.7、发明名称为“一种通信方法及相关设备”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
本发明涉及通信领域,具体涉及一种通信方法及相关设备。
背景技术
在网络设备与终端设备的交互过程中,当网络设备有下行数据需要发送给终端设备时,网络设备会向终端设备发送寻呼消息。终端设备在空闲态需要监听调度寻呼消息的物理下行控制信道(physical downlink control channel,PDCCH)。
为减少终端设备监听PDCCH的时间,引入一个非连续接收(discontinuous reception,DRX)机制。终端设备只需要在每一个DRX周期的一个寻呼时机(paging occasion,PO)监听PDCCH。
一个终端设备可以确定一个唯一的PO。但是,可能存在多个终端设备在同一个PO监听PDCCH。在大多数情况下,网络设备不会在一个PO同时寻呼多个终端设备。对于一个终端设备来说,不管该终端设备有没有被网络设备寻呼,该终端设备都需要在对应的PO上监听PDCCH,这样可能出现大量终端设备监听了PDCCH而没有被寻呼的现象,这样会增加未被寻呼的终端设备的功耗。比如,一个PO对应十个终端设备,当十个终端设备中只有一个终端设备被寻呼时,该十个终端设备都要监听PDCCH,这样没有被寻呼的九个终端设备都需要监听PDCCH,这样增加了未被寻呼的九个终端设备的功耗。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本申请中出现的术语“和/或”,可以是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本申请中字符“/”,一般表示前后关联对象是一种“或”的关系。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或模块的过程、方法、系统、产品或设备不必限于清楚地列出的 那些步骤或模块,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或模块。
在网络设备与终端设备的交互过程中,网络设备有下行数据需要发送给终端设备时,网络设备会向终端设备发送寻呼消息。终端设备在每个DRX周期中自己对应的PO监听PDCCH。
终端设备可以根据DRX周期和终端设备的唯一标识符来确定寻呼帧(paging frame,PF),进而确定寻呼子帧,该寻呼子帧即为PO,其中,该PF的系统帧号(system frame number,SFN)是通过如下公式计算出来的:
SFN mod T=(T div N)*(UE_ID mod N)。其中T为DRX的周期,N=min(T,nB),nB=4T,2T,T,T/2,T/4,T/8……(该nB的值为网络设备通过系统消息通知UE的),UE_ID=国际移动用户识别码(international mobile subscribe identification,IMSI)mod 1024。
一个系统帧由十个寻呼子帧构成,PO对应的寻呼子帧号可以根据i_s得到,该i_s可以根据如下公式计算出来:
i_s=floor(UE_ID/N)mod Ns,其中UE_ID=IMSI mod 1024,N=min(T,nB),nB=4T,2T,T,T/2,T/4,T/8……,Ns=max(1,nB/T)。
根据计算得到的i_s的值从表1中确定需要监听寻呼子帧号:
表1
Figure PCTCN2020099857-appb-000001
通过上述过程,针对一个终端设备,可以确定唯一一个PO,该终端设备在这个PO监听PDCCH。但是对于一个PO来说,可能对应多个终端设备,也就是说多个终端设备可能会在同一个PO监听PDCCH。在多数情况下,网络设备不会在一个PO同时寻呼多个终端设备。但是对一个终端设备来说,不管该终端设备有没有被网络设备寻呼,该终端设备在每个PO都需要监听PDCCH,这样可能出现大量对应同一个PO的终端设备监听了PDCCH却没有被寻呼,增加了未被寻呼的终端设备的功耗。比如,一个PO对应十个终端设备,当十个终端设备中只有一个终端设备被寻呼时,该十个终端设备都要监听PDCCH,这样没有被寻呼的九个终端设备都需要监听PDCCH,这样增加了未被寻呼的九个终端设备的功耗。
因此,本发明实施例一提供了一种通信方法,如图1所示,该方法可以包括:
101、第一设备向终端设备发送第一参数。
第一设备向终端设备发送第一参数,该第一参数可以为该终端设备的第一寻呼频度和/或第一寻呼概率,该第一寻呼频度为该终端设备在单位时间内被寻呼的次数,该单位时间可以为预先设定的一个时间段,具体不做限定。示例性的,该第一参数可以为20次/小时,表示终端设备在1小时内被寻呼20次。该第一寻呼概率可以为该终端设备在对应的PO被寻呼的概率。比如,该第一寻呼概率可以为20%,表示终端设备在该终端设备对应的PO被寻呼的概率为20%。该第一寻呼概率可以为第一设备根据一个PO对应的所有终端设备在单位时间内 被寻呼的概率确定的。示例性的,存在十个终端设备对应一个PO,该十个终端设备中在单位时间内被寻呼次数最多的终端设备被寻呼了100次,被寻呼次数最少的终端被寻呼了20次,则第一设备可以确定该被寻呼次数最多的终端设备的第一寻呼概率为100%,被寻呼次数最少的终端设备的第一寻呼概率为20%。该示例仅用于解释本申请,不应构成限定。该第一参数用于指示终端设备在至少一个唤醒信号(wake up signal,WUS)配置信息中确定第一WUS配置信息。
该第一设备可以为核心网设备,如移动管理实体(mobility management entity,MME)、接入和移动性管理功能实体(Access and Mobility Management Function,AMF)等,但不限于此。该终端设备可以为用户设备(user equipment,UE)、物联网设备等,但不限于此。此外,该终端设备被寻呼是具有规律的,在一个预先设定的时间段内被寻呼的频度是固定的。例如,终端设备在2010年1月1日9:00至10:00期间被寻呼20次,则该终端设备在2010年1月1日10:00至11:00期间同样被寻呼20次。该示例仅用于解释本申请,不应构成限定。
可以理解的是,该第一设备向终端设备发送该第一参数,可以通过其他设备中转,该其他设备包括第二设备。也就是说,步骤101可以为第一设备将第一参数发送给第二设备,第二设备再将该第一参数发送给终端设备,此处不做限制。
需要说明的是,第一设备在向终端设备发送第一参数之前,该第一设备需要先获取该第一参数。该第一设备可以统计该终端设备在预先设置的单位时间内被寻呼的次数,并将该终端设备在该预先设置的单位时间内被寻呼的次数记录下来,作为该第一参数的取值。例如,预先设置的单位时间为一小时,该第一设备在一小时内被寻呼20次,该第一设备可以统计该第一参数的取值为20。该示例仅用于解释本申请,不应构成限定。
示例性的,第一设备可以向终端设备发送附着接受(attach accept)消息或者跟踪区更新接受(tracking area update accept)消息,该附着接受消息或者跟踪区更新接受消息携带该第一参数。
102、第一设备向第二设备发送第一寻呼消息。
第一设备向第二设备发送第一寻呼消息,该第一寻呼消息包括终端设备的标识和该第一参数。该第一寻呼消息用于指示该第二设备寻呼终端设备,该终端设备的标识用于该第二设备确定该终端设备,该第一参数可以为该终端设备的第一寻呼频度,该第一参数用于指示第二设备在至少一个WUS配置信息中确定第一WUS配置信息。
该第二设备可以为接入网设备,如演进型节点B(E-UTRAN node B,eNB),5G基站(gNB)、通用移动通信系统演进陆地无线接入网(evolution universal mobile telecommunications system terrestrial radio access network,E-UTRAN)等。
103、第二设备向终端设备发送至少一个WUS配置信息。
第二设备向终端设备发送至少一个WUS配置信息,该至少一个WUS配置信息至少包含与该终端设备对应的第一WUS配置信息。该第一WUS配置信息包含第一WUS时频资源。
该至少一个WUS配置信息与第一参数存在对应关系。具体来说,该至少一个WUS配置信息可以与第一参数的取值范围存在对应关系。例如,该至少一个WUS配置信息包含K个WUS配置信息。在K个WUS配置信息中,任意一个WUS配置信息可以记为WUS j配置信息,其中K为正 整数,j为小于或等于K的正整数。一个WUS配置信息有一个与该WUS配置信息对应的索引。根据任意一个WUS配置信息的索引就可以确定对应的WUS配置信息。可以预先设置一个或多个寻呼频度的阈值。根据该一个或多个阈值可以确定至少两个取值范围,该至少两个取值范围中的每个取值范围对应一个WUS配置信息的索引。该索引可以是显示的或隐式的。在显式的方法中,一个V的取值范围对应一个确定的索引值,一个确定的索引值对应一个WUS配置信息,如表2所示。在隐式的方法中,WUS配置信息的索引没有一个确定的值,可以用其他隐含的方式表示。例如,K个WUS配置信息以列表形式表示,在列表中没有WUS配置信息的索引这一列。列表的第一行隐含了第一个WUS配置信息的索引为1……列表的第K行,隐含了该第K个WUS配置信息的索引为K。该列表中从第一个WUS配置信息到第K个WUS配置信息隐含对应了1至K的索引值。该第一参数的取值可以记为V,当V值确定时,可以根据V值确定与该V值对应的取值范围,从而确定与该取值范围对应的WUS配置信息的索引,然后根据该WUS配置信息的索引确定对应的WUS配置信息。该V的取值范围、WUS配置信息的索引、WUS配置信息之间的对应关系可以如下表2所示:
表2
V的取值范围 WUS配置信息的索引 WUS配置信息
V≤T 1 WUS 1配置信息的索引 WUS 1配置信息
T 1<V≤T 2 WUS 2配置信息的索引 WUS 2配置信息
…… …… ……
T M-1<V≤T M WUS K-1配置信息的索引 WUS K-1配置信息
T M<V WUS K配置信息的索引 WUS K配置信息
其中,T 1、T 2、……、T M-1、T M为预先设置的阈值,它们之间的关系可以为T 1≤T 2≤……≤T M-1≤T M。在具体实现过程中,也可以是多个V的取值范围对应一个WUS配置信息的索引和一个WUS配置信息。示例性的,在表2中,第一列多行对应第二列中的一行和第三列中的一行。第二设备可以向终端设备发送系统消息,该系统消息可以包含M个预先设置的阈值,如:T 1、T 2、……、T M-1、T M
在实际实施过程中,该WUS配置信息的索引可以为多级索引。示例性的,该一级索引可以包括至少一个二级索引。根据第一参数的取值范围可以确定一个一级索引,然后再根据预设方法确定该一级索引中具体的二级索引。每一个二级索引对应一个确定的WUS配置信息。根据预设方法确定该一级索引中的二级索引具体可以为根据终端设备的标识确定该一级索引中的二级索引。
示例性的,该预设方法可以为:先给二级索引按照1到W的顺序编号,B为终端设备对应的二级索引的编号。W为一级索引包含的二级索引数量,W为正整数,M为终端设备的唯一标识,例如临时移动用户标识(serving-temporary mobile subscriber identity,S-TMSI)或IMSI。则B的计算公式可以为:B=M mod W+Q,其中Q为大于或等于零且小于W的正整数,mod为取模运算。该示例仅用于解释本申请,不应构成限定。
在根据上述方法确定一级索引以及二级索引之后,可以根据该一级索引与二级索引确定一个确定的WUS配置信息。示例性的,该WUS K的索引可以为一级索引,该一级索引可以包 括WUS K1、WUS K1、WUS K3……等至少一个二级索引,每个二级索引对应一个WUS配置信息,在根据第一参数的取值范围确定一级索引之后,再根据终端设备的标识确定具体对应的二级索引。然后根据表3确定WUS配置信息。表3为一级索引、二级索引和WUS配置信息之间的对应关系,表3仅为一种示例,并不构成限制。

第二设备可以将上述取值范围与WUS配置信息的索引之间的对应关系发送给终端设备。该终端设备在收到该对应关系之后,可以根据第一参数的值(V)确定V的取值范围,从而确定该取值范围所对应的WUS配置信息的索引和对应的WUS配置信息。
在另一种实施方式中,该配置信息可以包含两部分,表4所示的该第一参数与WUS索引之间的对应关系和表5所示的WUS配置信息的索引和WUS配置信息之间的对应关系:

T 1<V≤T 2 WUS 2配置信息的索引
…… ……
T M-1<V≤T M WUS K-1配置信息的索引
T M<V WUS K配置信息的索引
该WUS配置信息的索引与WUS配置信息之间的关系可以用如下表5所示,其中WUS配置信息的索引可以是隐式的,例如WUS配置信息以列表的形式给出,WUS配置信息在列表中的顺序隐式指示了WUS配置信息的索引。
表5
WUS配置序号 WUS配置信息的索引 WUS配置信息
1 WUS 1配置信息的索引 WUS 1配置信息
2 WUS 2配置信息的索引 WUS 2配置信息

上述仅为一种实施方式,在实际实施过程中,也可以为直接根据第一参数的取值范围确定WUS配置信息,而不需要确定WUS配置信息的索引这个步骤,此处不做限定。
需要说明的是,步骤102和步骤103之间没有时间上的先后关系,可以是在第二设备向终端设备发送至少一个WUS配置信息之后,该第一设备再向第二设备发送第一寻呼消息。
104、终端设备确定该第一参数的取值范围并从该至少一个WUS配置信息中确定第一WUS配置信息。

可选的,在一种可能的实施方式中,终端设备可以根据该第一参数和预先设置的至少一个阈值确定该第一参数所在的取值范围,从而确定该取值范围对应的WUS配置信息的索引,该取值范围对应的WUS配置信息的索引即为第一WUS配置信息的索引。然后根据该取值范围对应的WUS配置信息的索引确定第一WUS配置信息。可以参照步骤103进行理解。
可选的,在一种可能的实现方式中,终端设备可以根据第一参数和预先设置的至少一个阈值确定第一参数所在的取值范围,然后直接根据该第一参数所在的取值范围确定与该取值范围相对应的第一WUS配置信息。可以参照步骤103进行理解。
可选的,在一种可能的实施方式中,终端设备可以根据第一参数和预先设置的至少一个阈值确定第一参数所在的取值范围,从而确定该取值范围对应的一级索引,该一级索引可以包括至少一个二级索引,终端设备可以根据预设方法确定该二级索引,具体可以为根据终端设备的标识确定该一级索引中的二级索引。该确定步骤可以参照步骤103进行理解,此处不再赘述。在确定该二级索引之后,可以根据该二级索引确定第一WUS配置信息。
105、终端设备根据该第一WUS配置信息确定第一WUS时频资源。
该第一WUS配置信息包含第一WUS时频资源的信息,该终端设备可以根据该第一WUS配置信息确定该第一WUS时频资源。
第一WUS时频资源可以包含以下至少一项:

(3)UE组数,其用于指示关联到一个WUS的UE的分组个数,或用于指示关联一个PO的UE的分组个数;
(4)频率位置信息,用于指示发送WUS的频率位置;在一种可能的实施方式中,频率位置信息可以用于指示发送WUS在寻呼窄带的频率位置;
(5)时间位置信息,用于指示发送WUS的时间位置;在一种可能的实施方式中,时间位置信息可以用于指示发送WUS相对于PO的时间位置,如发送WUS的结束时刻与所关联第一个PO的时间。
106、第二设备根据该第一参数从该至少一个WUS配置信息中确定第一WUS配置信息。
第二设备可以根据第一参数和预先设置的至少一个阈值确定第一参数的取值范围,再根据该第一参数的取值范围与第一WUS配置信息预先设置的对应关系从该至少一个WUS配置信息中确定第一WUS配置信息。该确定的过程可以参照步骤104进行理解,此处不再赘述。
需要说明的是,步骤106和步骤104没有时间上的先后关系,可以是该终端设备先确定第一WUS配置信息,也可以是该第二设备先确定该第一WUS配置信息。
107、第二设备根据第一WUS配置信息确定第一WUS时频资源。
该第一WUS配置信息包含第一WUS时频资源的信息,该第二设备可以根据该第一WUS配置信息确定该第一WUS时频资源。该第一WUS时频资源如步骤105所述,此处不再赘述。
108、第二设备在第一WUS时频资源上向终端设备发送第一WUS。
第二设备在步骤107中确定了第一WUS时频资源之后,在该第一WUS时频资源上向终端设备发送该第一WUS。
109、终端设备在第一时频资源上从第二设备接收第一WUS。
终端设备在步骤105中确定了第一WUS时频资源之后,在该第一WUS时频资源上接收该第一WUS。该第一WUS用于唤醒该终端设备,该终端设备被唤醒之后,在第一PO监听PDCCH,该第一PO为该终端设备对应的PO。
本申请实施例一提供了一种通信方法,该方法包括:终端设备从第一设备接收第一参数,该第一参数可以为终端设备的第一寻呼频度。第一参数对应至少一个唤醒信号WUS配置信息中的第一WUS配置信息,第一WUS配置信息包含第一WUS时频资源的信息;终端设备根据第一参数确定第一WUS时频资源;终端设备在第一WUS时频资源上从第二设备接收第一WUS,第一WUS用于唤醒终端设备并使得终端设备在第一寻呼时机PO监听物理下行控制信道PDCCH。在该方法中,终端设备可以根据从第一设备接收的第一参数确定第一WUS时频资源,然后在第一WUS时频资源上从第二设备接收第一WUS。在接收到该第一WUS之后再在第一寻呼时机PO监听PDCCH,这样可以减少终端设备监听了PDCCH却没有被寻呼的概率,减少终端设备的功耗。
在本申请实施例一中,根据终端设备在单位时间内被寻呼的频度以及预先设置的一个或多个阈值可以确定终端设备在单位时间内被寻呼的频度对应的取值范围,该取值范围对应相应的WUS。对应同一个PO的多个终端设备在单位时间内被寻呼的频度可能不同,这样对应一个PO的多个终端可能会对应不同的WUS。
由此,本申请实施例一提供的这种方案相当于基于不同的WUS对对应一个PO的多个终端 进行了分组。在对应一个PO的所有终端设备中,只有接收到对应WUS的对应终端设备才监听PDCCH,而不是所有该PO中的终端设备都监听PDCCH,这样可以减少未被寻呼的终端设备的功耗。在本方案实施之前,第一设备需要确定第二设备以及终端设备是支持基于WUS对终端设备进行分组的机制。例如,第二设备可以向第一设备发送第一指示消息,该第一设备根据第一指示消息确定该第二设备支持基于WUS对终端设备的分组;终端设备可以向第一设备发送第二指示消息,该第一设备可以根据该第二指示消息确定该终端设备支持基于WUS对终端设备的分组。示例性的,终端设备可以通过附着请求消息(attach request)或者跟踪区更新请求(tracking area update request)携带该第二指示消息。
在实施例一中,该第一参数为终端设备的第一寻呼频度或第一寻呼概率,该第一寻呼频度可以为该终端设备在单位时间内被寻呼的次数,该第一寻呼频率可以为终端设备在对应的PO被寻呼的概率。该第一寻呼频度和第一寻呼概率都可以用数值表示,可以根据该数值确定取值范围。在另一种实施方式中,该第一参数也可以为终端设备的第一寻呼概率等级,该第一寻呼概率等级可以表示该终端设备在单位时间内被寻呼的概率等级,该第一寻呼概率等级是第一设备根据该终端设备在单位时间内被寻呼的次数确定的。实施例二提供了一种通信方法,参照图2,该方法可以包括:
201、第一设备向终端设备发送第一参数。
第一设备向终端设备发送第一参数,该第一参数可以为第一寻呼概率等级,该第一寻呼概率等级可以为终端设备在单位时间内的寻呼概率等级,该第一寻呼概率等级为第一设备根据终端设备在单位时间内被寻呼的次数确定的。该单位时间可以为预先设定的一个时间段,具体不做限定。示例性的,该第一参数可以指示第一寻呼概率等级为低或高,例如,若第一设备统计终端设备在一小时内被寻呼次数小于或等于20次,则确定该终端设备的寻呼概率等级为低;若第一设备统计终端设备在一小时内被寻呼次数大于20次,则确定该终端设备的寻呼概率等级为高。该第一参数也可以为其他概率等级,如等级1、等级2……等。该示例仅用于解释本申请,不应构成限定。
该第一设备可以为核心网设备,如MME和AMF等,但不限于此。该终端设备可以为UE、物联网设备等,但不限于此。该终端设备被寻呼是具有规律的。在一个预先设定的时间段内被寻呼的频度是固定的。因此,在一个预先设定的时间段内被寻呼的概率等级是固定的。
可以理解的是,该第一设备向终端设备发送该第一参数,可以通过其他设备中转,该其他设备包括第二设备。也就是说,步骤201可以为第一设备将第一参数发送给第二设备,第二设备再将该第一参数发送给终端设备,此处不做限制。
202、第一设备向第二设备发送第一寻呼消息。
第一设备向第二设备发送第一寻呼消息,该第一寻呼消息包括终端设备的标识和该第一参数。该第一寻呼消息用于指示该第二设备寻呼终端设备,该终端设备的标识用于该第二设备确定该终端设备。该第一参数可以为该终端设备的第一寻呼概率等级,该第一参数用于指示第二设备在至少一个WUS配置信息中确定第一WUS配置信息。该第二设备可以为接入网设备,如eNB、gNBE-UTRAN等。
203、第二设备向终端设备发送至少一个WUS配置信息。
第二设备向终端设备发送至少一个WUS配置信息,该至少一个WUS配置信息至少包含与该终端设备对应的第一WUS配置信息。该第一WUS配置信息包含第一WUS时频资源。
该至少一个WUS配置信息与寻呼概率等级具有对应关系。例如,当寻呼概率等级为低或高时,该至少一个WUS配置信息与寻呼概率等级之间的对应关系可以如下表6:
表6
寻呼概率等级 WUS配置信息
WUS 1配置信息
WUS 2配置信息
在实际实施过程中,可以为多个寻呼概率等级对应一个WUS配置信息,例如,当寻呼概率等级包括高、次高、中、次低、低,5个等级时,该寻呼概率等级与WUS配置信息之间的对应关系可以如下表7:
表7
寻呼概率等级 WUS配置信息
低或次低 WUS 1配置信息
WUS 2配置信息
次高 WUS 3配置信息
WUS 4配置信息
第二设备可以将上述WUS配置信息与寻呼概率等级之间的对应关系发送给终端设备,终端设备收到该对应关系之后,可以根据该终端设备的第一寻呼概率等级确定对应的WUS配置信息。
上述至少一个WUS配置信息与寻呼概率等级之间的对应关系仅为示例性的实施方式,并不对本申请构成限定。在实际实施过程中,有可能设置N个寻呼概率等级,N为正整数。其中,可以设置一个或多个寻呼概率等级对应一个WUS配置信息,此处不做限定。
204、终端设备根据该第一参数从该至少一个WUS配置信息中确定第一WUS配置信息。
终端设备根据该第一参数及第一参数与第一WUS配置信息预先设置的对应关系从该至少一个WUS配置信息中确定第一WUS配置信息。示例性的,参照步骤203,若该第一参数为“低”,则根据该至少一个WUS配置信息与寻呼概率等级之间的对应关系,确定该第一WUS配置信息为WUS 1配置信息。
205、终端设备根据该第一WUS配置信息确定第一WUS时频资源。
参照实施例一中的步骤105,此处不再赘述。
206、第二设备根据该第一参数及第一参数与第一WUS配置信息预先设置的对应关系从该至少一个WUS配置信息中确定第一WUS配置信息。

207、第二设备根据第一WUS配置信息确定第一WUS时频资源。
参照实施例一中的步骤107进行理解,此处不再赘述。
208、第二设备在第一WUS时频资源上向终端设备发送第一WUS。
第二设备在步骤207中确定了第一WUS时频资源之后,在该第一WUS时频资源上向终端设备发送该第一WUS。
