本申请实施例中的UE也可称为终端设备、接入终端、用户单元、用户站、移动站、移动台(mobile station,MS)、移动终端(mobile Terminal,MT)、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请实施例中的UE可以是指向用户提供语音和/或数据连通性的设备,可以用于连接人、物和机,例如具有无线连接功能的手持式设备、车载设备等。本申请的实施例中的UE可以是手机(mobile phone)、平板电脑(Pad)、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备,虚拟现实(virtual reality,VR)设备、增强现实(augmented reality,AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。可选地,UE可以用于充当基站。例如,UE可以充当调度实体,其在V2X或D2D等中的UE之间提供侧行链路信号。比如,蜂窝电话和汽车利用侧行链路信号彼此通信。蜂窝电话和智能家居设备之间通信,而无需 通过基站中继通信信号。
本申请实施例中的网络设备可以是用于与UE通信的设备,该网络设备也可以称为接入网设备或无线接入网设备,如网络设备可以是基站。本申请实施例中的网络设备可以是指将UE接入到无线网络的无线接入网(radio access network,RAN)节点(或设备)。基站可以广义的覆盖如下中的各种名称,或与如下名称进行替换,比如:节点B(NodeB)、演进型基站(evolved NodeB,eNB)、下一代基站(next generation NodeB,gNB)、中继站、接入点、传输点(transmitting and receiving point,TRP)、发射点(transmitting point,TP)、主站MeNB、辅站SeNB、多制式无线(MSR)节点、家庭基站、网络控制器、接入节点、无线节点、接入点(access piont,AP)、传输节点、收发节点、基带单元(base band unit,BBU)、射频拉远单元(Remote Radio Unit,RRU)、有源天线单元(active antenna unit,AAU)、射频头(remote radio head,RRH)、中心单元(central unit,CU)、分布式单元(distributed unit,DU)、定位节点等。基站可以是宏基站、微基站、中继节点、施主节点或类似物,或其组合。
在一些实施例中,网络设备可以是固定的,也可以是移动的。例如,直升机或无人机可以被配置成充当移动网络设备,一个或多个小区可以根据该移动网络设备的位置移动。在其他示例中,直升机或无人机可以被配置成用作与另一网络设备进行通信的设备。在一些实施例中,网络设备可以是指CU或者DU,或者,网络设备可以包括CU和DU,或者,网络设备还可以包括AAU。应理解,网络设备可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上;还可以部署在空中的飞机、气球和卫星上。本申请实施例中对网络设备和在本申请实施例中所处的场景不做限定。
还应理解,本申请中的网络设备和UE的全部或部分功能也可以通过在硬件上运行的软件功能来实现,或者通过平台(例如云平台)上实例化的虚拟化功能来实现。
某些通信系统中引入了非公共网络(non-public networks,NPN),为了增加NPN网络部署的灵活性,NPN网络又可以分为独立非公共网络(stand-alone non-public networks,SNPN)及闭合接入组(closed access group,CAG)网络,前者通过公共陆地移动网络标识(public land mobile network identifier,PLMN ID)+网络标识(network identifier,NID)标识一个SNPN网络,后者通过PLMN ID+CAG ID标识一个CAG网络。
一个公共陆地移动网络(public land mobile network,PLMN)可以同时支持普通公共网络、SNPN网络及CAG网络的任意网络共享组合模式。例如,一个PLMN可以单独支持普通公共网络或者SNPN或者CAG网络,也可以支持普通公共网络与SNPN共享一个PLMN,甚至普通公共网络、SNPN及CAG网络同时关联一个PLMN都是允许的。普通公共网络、SNPN及CAG网络之间的逻辑部署关系可以如表1所示:
表1一个小区可能支持的网络标识配置示意
Figure PCTCN2021121265-appb-000001
表1中的参数i、j及k均为大于或等于1的正整数。如表1所示,从网络配置角度来看,一个小区可以同时配置公共网络PLMN ID列表信息和非公共网NPN网络标识列表信息,其中,非公共网NPN网络标识列表信息是可选参数(或者说,是可选配置)。对于CAG类型的NPN网络,允许一个PLMN ID关联一个CAG ID列表;对于SNPN类型的NPN网络,允许一个PLMN ID关联一个NID列表。
公共告警系统(public warning system,PWS)主要用于为终端设备提供各类告警消息,例如,地震海啸告警消息或者商业告警消息。终端设备可以通过接收网络设备发送的寻呼短消息中包含的PWS指示位判断网络设备是否准备发送PWS消息;对于公共陆地移动网络PLMN,网络设备默认支持PWS消息的发送,终端设备根据自身的PWS支持能力信息判断是否需要接收PWS相关消息。
目前,SNPN网络开始支持PWS消息发送业务,但在现有技术中,终端设备只按照网络标识优先级选择SNPN网络,并没有考虑所选择的SNPN网络是否支持PWS功能(即PWS消息业务),这样可能会使终端设备选择到一个不支持PWS功能的SNPN网络,从而会导致终端设备因错过危险告警消息而产生严重的后果。
为了解决上述技术问题,下面结合图2至图5,对本申请实施例进行详细地举例说明。
图2是本申请实施例的通信方法的一个示意性流程图。应理解,图2示出了通信方法的步骤或操作,但这些步骤或操作仅是示例,本申请实施例还可以执行其他操作或者图2中的各个操作的变形,或者,并不是所有步骤都需要执行,或者,这些步骤可以按照其他顺序执行。图2所示的方法200可以包括步骤S210及S220,具体如下:
S210,网络设备向终端设备发送第二信息。
其中,所述第二信息可以指示M个SNPN标识,M为正整数。示例性的,终端设备接收接入网设备通过系统广播消息或者专用信令发送的第二信息。
所述终端设备可以配置有第一信息。所述第一信息可以指示至少一个独立非公共网络SNPN标识是否支持PWS功能,所述PWS功能可以包括PWS消息的接收和/或发送等。
可选地,所述第一信息可以是静态配置的或动态配置的。例如,所述第一信息可以是协议默认规定的或网络设备配置的,其中,网络设备配置包括核心网设备配置或者接入网设备配置。
在一些实施例中,所述终端设备可以配置有第三信息,所述第三信息包括N个SNPN标识,N为正整数。可选地,所述第三信息可以为所述终端设备的NAS网络标识配置,预配置给所述终端设备。
例如,下述表2为终端设备配置的第三信息一种示例,具体如下:
表2终端设备配置的第三信息示例
NAS网络标识配置1:网络标识列表1
NAS网络标识配置2:网络标识列表2
NAS网络标识配置K:网络标识列表K
如表2所示,终端设备配置的第三信息包括K个NAS网络标识配置,一个NAS网络标识配置包含一组网络标识(即一个网络标识列表),K个NAS网络标识配置合起来包含N个SNPN标识,每一个NAS网络标识配置内包含的一个或者多个网络标识之间的网络标识优先级相同,不同NAS网络标识配置包含的网络标识之间的网络标识优先级可以相同或者不同,每一个NAS网络标识配置包含的网络标识对应的网络标识优先级通过协议默认配置或者通过网络设备配置。
下面通过下述多个示例,对所述第一信息的配置方式进行说明,具体如下:
方式一:协议默认配置
通信标准协议可以规定哪些SNPN网络默认支持或者默认不支持PWS功能,比如: 标准协议规定SNPN1和SNPN2对应的网络默认支持PWS功能,则每当终端设备获取上述第二信息和/或第三信息中包括SNPN1或者SNPN2,则终端设备无需额外信息即可获知第一信息,因为SNPN1或者SNPN2标识本身就包含第一信息,即SNPN1或者SNPN2网络默认支持PWS功能。
方式二:网络标识优先级
所述网络设备向所述终端设备发送所述第一信息,所述第一信息用于指示所述第三信息包含的N个SNPN标识中的至少一个SNPN标识支持(或不支持)PWS功能。例如,所述网络设备可以通过NAS消息向所述终端设备发送所述第一信息,所述网络设备可以为核心网设备,即:此时第一信息按照网络标识粒度进行配置,覆盖第三信息包含的N个SNPN标识中的每一个SNPN标识。
在一些实施例中,所述第一信息可以指示表2中所述第三信息中包含的N个SNPN标识中的每个SNPN标识支持(或不支持)PWS功能,即:此时第一信息按照网络标识粒度进行配置,覆盖第三信息包含的部分SNPN标识。
在一些实施例中,所述第一信息可以指示表2中所述第三信息中包含的N个SNPN标识中的部分SNPN标识支持(或不支持)PWS功能。
在一些实施例中,根据表2示例,所述第三信息中包含的N个SNPN标识可以分为K组SNPN标识,K为正整数。此时,所述第一信息可以指示所述K组SNPN标识中的每一组或者部分组是否支持PWS功能,即:此时第一信息按照表2中NAS网络标识配置粒度进行配置,覆盖第三信息包含的全部或者部分NAS网络标识配置组对应的网络标识。
例如,下述表3为第一信息与第三信息配置逻辑关系的一种示例,具体如下:
表3第一信息与第三信息配置逻辑关系示例
Figure PCTCN2021121265-appb-000002
如表3所示,终端设备的第三信息配置中包括K个网络标识列表(即K组网络标识),每个网络标识列表对应一个指示信息,该指示信息用于指示该组网络标识列表包含的全部网络标识是否支持PWS功能。
一种实现方式下,表3中的网络标识列表1可以包含3个网络标识,网络标识列表1对应的指示信息可以包括3个比特,这3个比特可以分别指示网络标识列表1包含的3个网络标识各自是否支持PWS功能。
另一种实现方式下,网络标识列表1对应的指示信息可以包括1个比特,这1个比特可以指示网络标识列表1包含的3个网络标识同时支持(或不支持)PWS功能。
方式三:

在一些实施例中,所述第一信息可以为网络标识粒度的指示信息,用于指示所述第二信息包含的M个SNPN标识中的每个SNPN标识是否支持PWS功能,即:此时第一信息按照网络标识粒度进行配置,覆盖第二信息包含的M个SNPN标识中的每一个SNPN标识。
在一些实施例中,所述第一信息可以为小区粒度的指示信息,用于指示所述终端设备当前所在的第一小区是否支持PWS功能。例如,所述第一信息可以指示所述终端设备当前所在的第一小区广播的全部SNPN标识是否支持PWS功能,即:此时第一信息按照小 区粒度进行配置,覆盖第二信息包含的全部SNPN标识。
例如,若所述第一信息可以指示所述终端设备当前所在的第一小区支持PWS功能,则所述第二信息中包含的所述M个SNPN标识中至少有一个SNPN网络支持PWS功能;或者,若所述第一信息可以指示所述终端设备当前所在的第一小区不支持PWS功能,则所述第二信息中包含的所述M个SNPN标识中没有一个SNPN网络支持PWS功能。

进一步地,所述接入层还可以通过层间交互消息(例如,第二层间交互消息)将所述第二信息传递给所述终端设备的非接入层(non-access stratum,NAS),由所述非接入层根据所述第一信息及所述第二信息选择所述目标SNPN标识,或者,由所述非接入层根据所述第一信息、所述第二信息以及第三信息选择所述目标SNPN标识。
可选地,所述第一信息和所述第二信息可以承载于同一个消息中,例如,所述网络设备可以通过系统广播消息向所述终端设备发送所述第一信息和所述第二信息。
进一步地,所述网络设备可以通过系统广播消息向所述终端设备发送所述第一信息和所述第二信息。相应地,所述终端设备的接入层可以接收所述网络设备发送的所述第一信息和所述第二信息,并通过层间交互消息(例如,第三层间交互消息)将所述第一信息和所述第二信息传递给所述终端设备的非接入层。
S220,所述终端设备根据第一信息及第二信息选择目标SNPN标识或者,所述终端设备根据第一信息、第二信息以及第三信息选择目标SNPN标识。
在本申请实施例中,所述终端设备可以根据下述多种方法选择所述目标SNPN标识,具体如下:
方法一:所述终端设备可以优先考虑网络标识优先级高低,在同一网络标识优先级对应多个SNPN网络标识时,再结合是否支持PWS功能从该多个SNPN网络标识中选择所述目标SNPN标识。
在一些实施例中,所述终端设备可以确定所述M个SNPN标识中对应第一优先级的第一SNPN标识集合,并根据所述第一信息从所述第一SNPN标识集合中选择所述目标SNPN标识。
可选地,在从所述第一SNPN标识集合中选择所述目标SNPN标识时,所述终端设备可以根据所述第一信息确定所述第一SNPN标识集合中是否存在支持PWS功能的SNPN标识;若所述第一SNPN标识集合中存在所述支持PWS功能的SNPN标识,则所述终端设备可以选择所述支持PWS功能的SNPN标识作为所述目标SNPN标识;若所述第一SNPN标识集合中的SNPN标识均不支持PWS功能,则所述终端设备可以根据网络标识优先级从所述M个SNPN标识中选择所述目标SNPN标识。
例如,所述终端设备可以先从所述M个SNPN标识中选择网络标识优先级最高的一个或多个SNPN标识,即第一SNPN标识集合;随后,可以根据所述第一信息确定所述第一SNPN标识集合中是否存在支持PWS功能的SNPN标识;若所述第一SNPN标识集合中存在所述支持PWS功能的SNPN标识,则所述终端设备可以选择所述支持PWS功能的SNPN标识作为所述目标SNPN标识;若所述第一SNPN标识集合中的SNPN标识均不支持PWS功能,则所述终端设备可以从所述M个SNPN标识中选择网络标识优先级最高的SNPN标识作为所述目标SNPN标识。
在一些实施例中,所述终端设备可以确定所述M个SNPN标识中对应第一优先级的第一SNPN标识集合,并根据所述第一信息从所述第一SNPN标识集合中选择所述目标SNPN标识。若所述第一SNPN标识集合中存在所述支持PWS功能的SNPN标识,则所 述终端设备可以选择所述支持PWS功能的SNPN标识作为所述目标SNPN标识;若所述第一SNPN标识集合中的SNPN标识均不支持PWS功能,则所述终端设备确定所述M个SNPN标识中第二优先级的第二SNPN标识集合,并根据所述第一信息从所述第二SNPN标识集合中选择所述目标SNPN标识。
若所述第二SNPN标识集合中的SNPN标识均不支持PWS功能,则所述终端设备可以确定所述M个SNPN标识中第三优先级的第三SNPN标识集合,并根据所述第一信息从所述第三SNPN标识集合中选择所述目标SNPN标识,依此类推,直到选择出一个支持PWS功能的SNPN网络,或者在遍历一遍所述M个网络标识后仍然不能选择一个支持PWS功能的SNPN网络,则所述终端设备可以放弃选择支持PWS功能的SNPN网络,此时,所述终端设备可以只考虑网络标识优先级选择SNPN网络,即所述终端设备可以从所述M个SNPN标识中选择网络标识优先级最高的SNPN标识作为所述目标SNPN标识。
例如,所述终端设备可以先从所述M个SNPN标识中选择网络标识优先级最高的一个或多个SNPN标识,即第一SNPN标识集合;随后,可以根据所述第一信息确定所述第一SNPN标识集合中是否存在支持PWS功能的SNPN标识;若所述第一SNPN标识集合中存在所述支持PWS功能的SNPN标识,则所述终端设备可以选择所述支持PWS功能的SNPN标识作为所述目标SNPN标识;若所述第一SNPN标识集合中的SNPN标识均不支持PWS功能,则所述终端设备可以从所述M个SNPN标识中选择网络标识优先级第二高的第二SNPN标识集合,并根据所述第一信息从所述第二SNPN标识集合中选择所述目标SNPN标识。
若所述第二SNPN标识集合中的SNPN标识均不支持PWS功能,则所述终端设备可以从所述M个SNPN标识中选择网络标识优先级第三高的第三SNPN标识集合,并根据所述第一信息从所述第三SNPN标识集合中选择所述目标SNPN标识,依此类推,直到选择出一个支持PWS功能的SNPN网络,或者在遍历一遍所述M个网络标识后仍然不能选择一个支持PWS功能的SNPN网络,则所述终端设备可以从所述M个SNPN标识中选择网络标识优先级最高的SNPN标识作为所述目标SNPN标识。
方法二:所述终端设备可以优先考虑支持PWS功能,在有多个SNPN标识支持PWS功能时,再结合网络标识优先级从该多个SNPN标识中选择支持PWS功能的SNPN标识作为所述目标SNPN标识。
在一些实施例中,所述终端设备可以根据所述第一信息将所述M个SNPN标识中支持PWS功能的SNPN标识确定为第四SNPN标识集合;若所述M个SNPN标识中存在支持PWS功能的SNPN标识,则所述终端设备选择所述第四SNPN标识集合中优先级最高的SNPN标识作为所述目标SNPN标识;若所述第四SNPN标识集合中的SNPN标识均不支持PWS功能,则所述终端设备可以根据网络标识优先级从所述M个SNPN标识中选择所述目标SNPN标识。
例如,所述终端设备可以优先挑选出所述M个SNPN标识中的支持PWS功能的SNPN标识,如果其中支持PWS功能的SNPN标识有多个,则可以进一步选择网络标识优先级最高的SNPN标识作为所述目标SNPN标识;如果所述M个SNPN标识中的SNPN标识均不支持PWS功能,则所述终端设备可以根据网络标识优先级从所述M个SNPN标识中选择所述目标SNPN标识。
在一些实施例中,所述终端设备可以配置有第四信息,所述第四信息指示所述终端设备优先选择支持PWS功能的SNPN标识。例如,所述第四信息可以通过预配置过程配置或者通过网络设备配置过程配置,其中网络设备配置过程包括系统广播消息配置方式或者专用信令配置方式。
相应地,所述终端设备可以根据所述第一信息、所述第二信息及所述第四信息,选择所述目标SNPN标识或者,所述终端设备可以根据所述第一信息、所述第二信息、所述第三信息及所述第四信息,选择所述目标SNPN标识。
在一些实施例中,所述终端设备在所述第四信息指示优先选择支持PWS功能的SNPN标识时,才会根据上述多种方法选择所述目标SNPN标识;否则,终端设备在进行网络标识选择时只考虑各网络标识对应的网络标识优先级。
在一些实施例中,在所述第一信息可以指示所述终端设备当前所在的第一小区不支持PWS功能时,所述终端设备还可以根据下述多种方案选择所述目标SNPN标识,具体如下:
方案一:
在一些实施例中,所述终端设备可以从所述候选SNPN标识集合中选择所述目标SNPN标识,其中,候选SNPN标识集合可以包括所述第三信息包含的N个SNPN标识中排除掉所述第二信息包含的M个SNPN标识之后的SNPN标识。
可选地,终端设备的NAS层可以排除掉所述终端设备AS层传递的全部网络标识(即所述第二信息包含的M个SNPN标识),在终端设备的NAS层的剩余网络标识配置信息(即所述候选SNPN标识)中按照网络标识优先级选择所述目标SNPN标识。
例如:终端设备的NAS网络标识配置中包含网络标识PLMN1、PLMN2和PLMN3(即所述N个SNPN标识),小区1(即所述第一小区)广播其支持的网络标识为PLMN1、PLMN2和PLMN4(即所述M个SNPN标识)且PWS功能指示信息(即所述第一信息)指示当前小区不支持PWS功能,则终端设备的NAS层可以排除掉NAS网络标识配置中的PLMN1、PLMN2,也就是说,此时,所述终端设备只能选择网络标识PLMN3进行网络注册尝试。
方案二:
在一些实施例中,所述终端设备可以重新搜索第二小区;并从所述第二小区提供的SNPN标识集合中选择所述目标SNPN标识。
可选地,所述终端设备的非接入层可以通过第一层间交互消息向所述终端设备的接入层发送第一指示信息,所述第一指示信息可以用于指示所述接入层重新搜索小区;响应于所述第一指示信息,所述接入层可以搜索所述第二小区。也就是说,终端设备的NAS层可以通过层间交互消息告知终端设备的AS层重新搜索一个小区。
进一步地,所述NAS层还可以向所述AS层发送第二指示信息,所述第二指示信息包括以下至少一项:
禁止使用最近一次搜索到的小区对应物理小区标识(physical cell identity,PCI)进行小区搜索的指示信息;
禁止使用最近一次搜索到的小区对应PCI进行小区搜索的禁止时长配置信息;
禁止使用最近一次搜索到的小区对应频点进行小区搜索的指示信息;
禁止使用最近一次搜索到的小区对应频点进行小区搜索的禁止时长配置信息;
禁止驻留到与最近一次搜索到的小区对应跟踪区标识(tracking area code,TAC)相同的小区上的指示信息。
也就是说,所述终端设备的NAS层还可以向终端设备的AS层提供重新搜索辅助信息(第二指示信息),以便于所述终端设备重新搜索第二小区。
在一种实现方式中,所述第一指示信息和所述第二指示信息可以在同一条消息中传递或者通过不同消息传递,本申请对此不做限定。
在另一种实现方式中,所述第一指示信息可以不出现,此时,所述第一指示信息的含义被所述第二指示信息隐式包含,因而只需要提供第二指示信息终端设备接入层就知道终端设备非接入层正在请求重新搜索小区,本申请对此不做限定。
在一些实施例中,所述终端设备在所述第四信息指示优先选择支持PWS功能的SNPN标识时,才会根据上述方法选择所述目标SNPN标识;否则,终端设备在进行网络标识选择时只考虑各标识对应的网络标识优先级。
在本申请实施例中,所述终端设备根据所述第一信息及所述第二信息选择目标SNPN 标识,或者,所述终端设备根据所述第一信息、所述第二信息以及所述第三信息选择目标SNPN标识,可以优先选择在支持PWS功能的SNPN网络上进行注册,从而有助于所述终端设备及时接收到PWS消息。
