Description

无线通信方法及设备 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及设备。
背景技术
新空口(New Radio,NR)16版本(R16)引入了非公共网络(Non-public Network,NPN),为了增加NPN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,通过公共陆地移动网络(Public Land Mobile Network,PLMN)标识(Identifier,ID)和网络标识(Network Identifier,NID)确定一个SNPN,通过PLMN ID和CAG标识(CAG ID)确定一个CAG网络。
通常,需要依赖运营商提供NPN,但针对临时NPN的布网需求,比如针对临时演唱会通信或临时应急通信部署临时NPN,每次都依赖运营商提供临时NPN并不是一种高效的建网模式,基于此,运营商通过协议授权的方式允许第三方建立自己的网络似乎更加高效。这些第三方部署的NPN网络拥有全新的网络特征,网络侧通常使用系统广播信息将这些全新的网络特征信息通知给终端设备,只有满足这些全新的网络特征信息对应的约束条件的终端设备才能接入第三方部署的NPN网络。
而在终端移动性控制过程中,例如:终端设备的移动导致接入网设备的切换,源接入网设备需要判断是否可以切换至目标接入网设备。目前的切换判决过程中,由于源接入网设备并没有获取到终端设备是否支持第三方NPN网络的配置信息,导致无法切换至第三方NPN网络对应的目标接入网设备,即无法为终端设备选择合适的目标小区。
发明内容
本申请实施例提供了一种无线通信方法及设备,从而可以为终端设备选择合适的目标小区。
第一方面,提供了一种无线通信方法,包括:接收第二接入网设备或者核心网设备发送的第一消息,第一消息包括终端粒度的NPN约束配置信息;其中,NPN约束配置信息用于辅助接入网侧的终端移动性控制过程。

第九方面,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、第二方面或其各实现方式中的方法。
综上,在本申请中,第一接入网设备可以获取到终端粒度的NPN约束配置信息,基于此,第一接入网设备在进行接入网设备的切换时,可以考虑NPN网络,如第三方NPN网络对应的目标接入网设备,从而可以为终端设备选择合适的目标小区。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。针对本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
图1是本申请实施例的一个应用场景的示意图。
如图1所示,通信系统100可以包括终端设备110和接入网设备120。接入网设备120可以通过空口与终端设备110通信。终端设备110和接入网设备120之间支持多业务传输。
应理解,本申请实施例仅以通信系统100进行示例性说明,但本申请实施例不限定于此。也就是说,本申请实施例的技术方案可以应用于各种通信系统,例如:长期演进(Long Term Evolution,LTE)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、5G通信系统(也称为新无线(New Radio,NR)通信系统),或未来的通信系统等。
以5G通信系统为例,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。
在5G网络环境中,为了降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定义了一个新的无线资源控制(Radio Resource Control,RRC)状态,即RRC_INACTIVE(去激活)状态。这种状态有别于RRC_IDLE(空闲)和RRC_CONNECTED(连接)状态。RRC_IDLE:移动性为基于终端设备的小区选择重选,寻呼由核心网(Core Network,CN)发起,寻呼区域由CN配置。接入网设备侧不存在终端设备接入层(Access Stratum,AS)上下文,也不存在RRC连接。RRC_CONNECTED:存在RRC连接,接入网设备和终端设备存在UE AS上下文;接入网设备知道终端设备的位置是具体小区级别的。移动性是接入网设备控制的移动性。终端设备和接入网设备之间可以传输单播数据。RRC_INACTIVE:移动性为基于终端设备的小区选择重选,存在CN-NR之间的连接,终端设备AS上下文存在某个接入网设备上,寻呼由无线接入网(Radio Access Network,RAN)触发,基于RAN的寻呼区域由RAN管理,接入网设备知道终端设备的位置是基于RAN的寻呼区域级别的。
在图1所示的通信系统100中,接入网设备120可以是与终端设备110通信的接入网设备。接入网设备可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备110(例如UE)进行通信。
接入网设备120可以是长期演进(Long Term Evolution,LTE)系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是下一代无线接入网(Next Generation Radio Access Network,NG RAN)设备,或者是NR系统中的基站(gNB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该接入网设备120可以为中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器,或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的接入网设备等。
终端设备110可以是任意终端设备,其包括但不限于与接入网设备120或其它终端设备采用有线或者无线连接的终端设备。
例如,所述终端设备110可以指接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、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。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进网络中的终端设备等。
终端设备110可以用于设备到设备(Device to Device,D2D)的通信。
无线通信系统100还可以包括与基站进行通信的核心网设备130,该核心网设备130可以是5G核心网(5G Core,5GC)设备,例如,接入与移动性管理功能(Access and Mobility Management Function,AMF),又例如,认证服务器功能(Authentication Server Function,AUSF),又例如,用户面功能(User Plane Function,UPF),又例如,会话管理功能(Session Management Function,SMF)。可选地,核心网设备130也可以是LTE网络的分组核心演进(Evolved Packet Core,EPC)设备,例如,会话管理功能+核心网络的数据网关(Session Management Function+Core Packet Gateway,SMF+PGW-C)设备。应理解,SMF+PGW-C可以同时实现SMF和PGW-C所能实现的功能。在网络演进过程中,上述核心网设备也有可能叫其它名字,或者通过对核心网的功能进行划分形成新的网络实体,对此本申请实施例不做限制。
通信系统100中的各个功能单元之间还可以通过下一代网络(next generation,NG)接口建立连接实现通信。
例如,终端设备通过NR接口与接入网设备建立空口连接,用于传输用户面数据和控制面信令;终端设备可以通过NG接口1(简称N1)与AMF建立控制面信令连接;接入网设备例如下一代无线接入基站(gNB),可以通过NG接口3(简称N3)与UPF建立用户面数据连接;接入网设备可以通过NG接口2(简称N2)与AMF建立控制面信令连接;UPF可以通过NG接口4(简称N4)与SMF建立控制面信令连接;UPF可以通过NG接口6(简称N6)与数据网络交互用户面数据;AMF可以通过NG接口11(简称N11)与SMF建立控制面信令连接;SMF可以通过NG接口7(简称N7)与PCF建立控制面信令连接。
图1示例性地示出了一个接入网设备、一个核心网设备和两个终端设备,可选地,该无线通信系统100可以包括多个接入网设备,并且每个接入网设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。

NR R16引入了NPN,为了增加NPN部署的灵活性,NPN又可以分为SNPN及CAG网络,通过PLMN ID和NID确定一个SNPN,通过PLMN ID和CAG ID确定一个CAG网络。以SNPN为例,可以使用PLMN ID和NID作为一个SNPN的标识,签约了某一SNPN业务的用户会配置相应的用户永久标识符(Subscriber Permanent Identifier,SUPI)和签约信息,存储在终端设备和核心网络侧。一个签约了SNPN业务的用户需要支持SNPN接入模式(SNPN access mode),配置为SNPN接入模式的用户只能通过SNPN接入网络,未配置为SNPN接入模式的用户可以执行PLMN选择流程。其中SNPN接入模式的配置方式(激活、去激活等)由终端设备来实现。在初始接入和小区重选过程中,接入网设备需要广播自身支持的NID和相应的PLMN ID信息,配置了SNPN接入模式的用户可以根据自己的签约信息选择可接入的SNPN小区,核心网设备也可以根据用户的签约信息对用户的身份进行认证。
一个PLMN可以同时支持普通公共网络、SNPN及CAG网络中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、SNPN或CAG网络,也可以支持普通公共网络与SNPN的网络共享组合模式,甚至支持普通公共网络、SNPN及CAG网络的网络共享组合模式。换言之,可以是普通公共网络、SNPN或CAG网络被一个PLMN支持,也可以是普通公共网络与SNPN同时共享一个PLMN网络,甚至普通公共网络、SNPN及CAG网络同时共享一个PLMN网络。下面结合表1可以更加清晰反映普通公共网络、SNPN及CAG网络之间的逻辑部署关系。

Figure PCTCN2021071341-appb-000002
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,非公共网NPN网络标识列表信息是NR R16引入的可选参数,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。
表1中的参数N、M、W均为大于等于1的正整数。
图2是本申请实施例提供的普通公共网络、SNPN及CAG网络之间的组网组合关系示意图。
如图2所示,一个物理小区可以同时被多个PLMN网络共享,每一个PLMN逻辑小区可以组建自己独有的非公共网络。可选的,可通过物理小区标识(Physical Cell Identities,PCI)来区分不同的物理小区。NR系统物理小区标识总共有1008个。PCI是用于区分不同小区的无线信号,保证在相关小区覆盖范围内没有相同的物理小区标识。一个PLMN下可以自由部署普通公共网络、SNPN及CAG网络的任意网络共享组合。可选的,一个物理小区部署的独立SNPN子网络个数、独立CAG子网络个数或SNPN与CAG子网络的总个数均不能超过12。
在蜂窝系统中传统的小区切换或者接入网设备切换过程如下:
图3是本申请实施例提供的蜂窝系统中的区切换或者接入网设备切换过程的流程图,如图3所示,该过程包括如下步骤:
S310:终端设备在收到源接入网设备测量配置后,在测量条件满足时,启动相应的测量过程。
S320:终端设备在测量结果上报条件满足后,将测量到的结果上报给源接入网设备。
S330:源接入网设备收到终端设备发送的测量报告之后,结合根据本地规则作出切换判决。
S340:若源接入网设备确定可以进行小区切换,则会向目标接入网设备发送切换请求。
S350:目标接入网设备收到源接入网设备发送的切换请求后,根据本地负载等信息判断是否可以接受该切换请求。
S360:如果目标接入网设备确定可以接受该切换请求,则向源接入网设备发送切换命令。
S370:源小区收到目标接入网设备发送的切换命令之后,以透传的方式将该切换命令转发给终端设备。
S380:终端设备收到切换命令后,存储切换命令中的配置信息。
S390:终端设备根据切换命令中的配置信息,接入至目标接入网设备。
如上所述,目前的切换判决过程中,由于源接入网设备并没有获取到终端设备是否支持第三方NPN网络的配置信息,导致无法切换至第三方NPN网络对应的目标接入网设备,即无法为终端设备选择合适的目标小区。
为了解决上述技术问题,本申请提供一种无线通信方法及设备。其中,源接入网设备可以获取到终端设备是否支持第三方NPN网络的配置信息,基于此,源接入网设备在进行接入网设备的切换时,可以考虑第三方NPN网络对应的目标接入网设备,以为终端设备选择合适的目标小区。
