Description

无线通信方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域,并且更具体地,涉及一种无线通信方法、终端设备和网络设备。
背景技术
为了能够通知处于无线资源控制(Radio Resource Control,RRC)非激活态(RRC_INACTIVE)的终端设备进入连接态,新无线(New Radio,NR)引入了接入网寻呼机制。
其中,接入网发送的寻呼过程包括:接入网将终端设备从连接态释放到非激活态,此时接入网仍然保存有终端设备接入层(Access Stratum,AS)上下文。其中,接入网将终端设备从连接态释放到非激活态过程中,会配置给终端设备一个寻呼区域配置信息,该寻呼区域配置信息可以包括以下任一项:闭合接入组标识(Closed Access Group Identifier,CGI)列表信息,跟踪区标识(Tracking Area Identity,TAI)列表信息,接入网区域码列表信息。其中,接入网和终端设备都维护有该寻呼区域配置信息,如果终端设备的驻留小区的对应配置与接入网配置给终端设备配置的寻呼区域配置信息中的任意一条配置不匹配,则终端设备触发接入网通知区域更新(RAN Notification Area Update,RNAU),使得接入网可以给终端设备配置新的寻呼区域配置信息;否则,后续接入网发送的寻呼过程就会失败。
然而,在非地面网络(Non-Terrestrial Network,NTN)系统中,由于卫星相对地面高速移动,因此,终端设备的驻留小区会发生频繁变化,如果继续采用如上的RNAU触发机制,会导致终端设备功耗过大的问题。

第十三方面,提供了一种计算机程序,当其在计算机上运行时,使得计算机执行上述第一方面至第三方面中任一方面或其各实现方式中的方法。
通过上述技术方案,终端设备不会因为终端设备的驻留小区的对应配置与接入网配置给终端设备配置的寻呼区域配置信息中的任意一条配置不匹配而触发RNAU。而是终端设备根据上述第一配置信息和终端设备的运动信息进行RNAU,这种方式相对于现有的RNAU触发方式,不会造成频繁的触发RNAU,从而可以降低终端设备的功耗。

应理解,本文中术语“系统”和“网络”在本文中常可互换使用。本文中术语“和/或”用来描述关联对象的关联关系,例如表示前后关联对象可存在三种关系,举例说明,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。本文中字符“/”一般表示前后关联对象是“或”的关系。
在本申请实施例的描述中,术语“对应”可表示两者之间具有直接对应或间接对应的关系,也可以表示两者之间具有关联关系,也可以是指示与被指示、配置与被配置等关系。
为了清楚地阐述本申请实施例的思想,首先对本申请实施例的相关技术内容进行简要描述。本申请实施例包括以下内容中的至少部分内容。
5G的主要应用场景为:增强移动超宽带(Enhance Mobile Broadband,eMBB)、低时延高可靠通信(Ultra-Reliable and Low Latency Communication,URLLC)、大规模机器类通信(massive Machine Type of Communication,mMTC)。eMBB仍然以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速。由于eMBB可能部署在不同的场景中,便如室内,市区,农村等,其能力和需求的差别也比较大,所以不能一概而论,必须结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。mMTC的典型特点包括:高连接密度,小数据量,时延不敏感业务,模块的低成本和长使用寿命等。
非激活态是NR系统引入的一种新的RRC状态,目的在于减少终端设备进入连接态的时延,接 入网仍然会保持终端设备AS上下文,在核心网看来,终端设备仍然处于连接态,因为核心网与接入网之间终端设备粒度的NG接口连接仍然保持,只是接入网与终端设备之间的Uu接口连接被释放,相比于空闲态需要建立完整的Un接口以及NG接口连接,处于非激活态的终端设备只需要建立Uu口连接,就能进入连接态,从而减少了终端设备进入连接态时延。
为了能够通知处于非激活态的终端设备进入连接态,NR引入了接入网寻呼机制,每当核心网需要给某终端设备下发数据,且该终端设备处于非激活态时,接入网就会触发接入网寻呼过程,以通知终端设备进入连接态,寻呼区域配置信息(即接入网寻呼区域配置)是接入网在将终端设备释放到非激活态时配置给终端设备的,寻呼区域配置信息同时在接入网侧与终端设备侧维护,可以包括如下配置形式任一项:CGI列表信息,TAI列表信息,接入网区域码列表信息。其中,每一个CGI用公共陆地移动网络(Public Land Mobile Network,PLMN)ID+小区(Cell)ID标识,每一个TAI用PLMN ID+TAC ID标识,每一个接入网区域码用PLMN ID+TAC ID+接入网区域码(RAN Area Code,RANAC)ID标识。
接入网维护寻呼区域配置信息的原因是:需要使用该配置发送接入网寻呼消息,从而找到被寻呼终端、而终端设备也需要维护该配置,是为了接入网和终端设备理解的一致性,如果终端设备的驻留小区的对应配置与接入网配置给终端设备的寻呼区域配置信息中的任意一条配置不匹配,则终端设备会触发RNAU,使得接入网可以给终端设备配置新的寻呼区域配置信息;否则,后续接入网发送的寻呼过程就会失败。
如上所述,在NTN系统中,由于卫星相对地面高速移动,因此,终端设备的驻留小区会发生频繁变化,如果继续采用如上的RNAU触发机制,会导致终端设备功耗过大的问题。
下面将对本申请技术方案进行详细阐述:

可选的,第一配置信息携带在系统广播消息或者专用信令中,但不限于此。
可选的,专用信令为连接释放信令,但不限于此。
可选的,周期性触发RNAU的配置信息包括:RNAU的默认执行周期、终端设备的位移评估周期和终端设备的至少一个位移评估阈值。
应理解的是,RNAU的周期指的是终端设备每隔多长时间执行一次RNAU。

应理解的是,终端设备的位移评估周期指的是用于对终端设备进行位移评估的周期。
应理解的是,至少一个位移评估阈值构成多个位移评估阈值范围,每个位移评估阈值范围对应上述默认执行周期的一个调整参数。
可选的,默认执行周期的调整参数用于调整默认执行周期,其中,终端设备可以根据调整参数通过如下至少一种方式调整默认执行周期,但不限于此:
在默认执行周期的基础上加上调整参数,调整参数取值可正可负;

应理解的是,本申请对上述调整参数不做限制。
可选的,上述终端设备的位移相关信息包括至少一个位移阈值,但不限于此。

实施例2
如上所述,终端设备可以根据周期性触发RNAU的配置信息和终端设备的运动信息进行RNAU。下面对此进行详细说明:
可选的,终端设备的运动信息为终端设备在位移评估周期内的位移量。终端设备根据至少一个位移评估阈值确定其在位移评估周期内的位移量对应的位移阈值范围,根据该位移阈值范围在默认执行周期的至少一个调整参数中确定第一调整参数,最后,采用默认执行周期进行RNAU,或者,根据第一调整参数调整默认执行周期,以周期性进行RNAU。
应理解的是,假设终端设备在默认执行周期的基础上乘以调整参数,以调整默认执行周期。那么当终端设备确定的第一调整参数为1时,这种情况,表示无需调整默认执行周期,因此,终端设备采用默认执行周期进行RNAU。或者,假设终端设备在默认执行周期的基础上加上调整参数,以调整默认执行周期。那么当终端设备确定的第一调整参数为0时,这种情况,表示无需调整默认执行周期,因此,终端设备采用默认执行周期进行RNAU。
可选的,终端设备在位移评估周期内的位移量越大,则RNAU的调整后的周期越小,终端设备在位移评估周期内的位移量越小,则RNAU的调整后的周期越大,但不限于此。
示例1,假设终端设备被配置了两个位移评估阈值,分别为S1和S2,其中,S1<S2。因此,这两个位移评估阈值构成三个位移评估阈值范围,分别是小于或等于S1,小于S1且大于或等于S2,和,大于S2。假设将这个三个位移评估阈值范围称为位移评估阈值范围1、位移评估阈值范围2和位移评估阈值范围3,假设终端设备在默认执行周期的基础上乘以调整参数,并且位移评估阈值范围1、位移评估阈值范围2和位移评估阈值范围3分别对应的调整参数是1,2和3。那么如果终端设备确定其在位移评估周期内的位移量所属的位移评估阈值范围是位移评估阈值范围1,则说明终端设备处于普通状态或者正常状态,这时对应的调整参数是1,即终端设备采用默认执行周期进行RNAU。如果终端设备确定其在位移评估周期内的位移量所属的位移评估阈值范围是位移评估阈值范围2,则说明终端设备处于中速状态,这时对应的调整参数是2,即终端设备采用T/2进行RNAU。T表示默认执行周期。如果终端设备确定其在位移评估周期内的位移量所属的位移评估阈值范围是位移评估阈值范围3,则说明终端设备处于高速状态,这时对应的调整参数是3,即终端设备采用T/3进行RNAU。
示例2,假设终端设备被配置了两个位移评估阈值,分别为S1和S2,其中,S1<S2。因此,这两个位移评估阈值构成三个位移评估阈值范围,分别是小于或等于S1,小于S1且大于或等于S2,和,大于S2。假设将这个三个位移评估阈值范围称为位移评估阈值范围1、位移评估阈值范围2和位移评估阈值范围3,假设终端设备在默认执行周期的基础上加上调整参数,并且位移评估阈值范围1、位移评估阈值范围2和位移评估阈值范围3分别对应的调整参数是0,-1和-2。那么如果终端设备确定其在位移评估周期内的位移量所属的位移评估阈值范围是位移评估阈值范围1,则说明终端设备处于普通状态或者正常状态,这时对应的调整参数是0,即终端设备采用默认执行周期进行RNAU。如果终端设备确定其在位移评估周期内的位移量所属的位移评估阈值范围是位移评估阈值范围2,则说明终端设备处于中速状态,这时对应的调整参数是-1,即终端设备采用T-1进行RNAU。如果终端设备确定其在位移评估周期内的位移量所属的位移评估阈值范围是位移评估阈值范围3,则说明终端设备处于高速状态,这时对应的调整参数是-2,即终端设备采用T-2进行RNAU。
应理解的是,示例1和示例2中根据位移评估阈值确定位移评估阈值范围的划分方式,不局限于上述划分方式,例如:三个位移评估阈值范围,分别是小于S1,大于或等于S1且大于或等于S2,和,大于S2。或者,三个位移评估阈值范围,分别是小于S1,大于或等于S1且大于S2,和,大于或等于S2。
综上,在本申请中,终端设备根据周期性触发RNAU的配置信息和终端设备的运动信息进行RNAU。这种方式相对于现有的RNAU触发方式,不会造成频繁的触发RNAU,从而可以降低终端设备的功耗。
