具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容,下面结合附图对本申请实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本申请实施例。
在对本申请实施例提供的网络选择方法进行详细说明之前,先对相关技术中NPN进行简要说明。
在长期演进(Long Term Evolution,LTE)网络和新无线(New Radio,NR)网络中,通常部署公共网络,即公共陆地移动网络(Public Land Mobile Network,PLMN)。但是,在一些场景中,如办公场景、家庭场景、工厂等,为了能够更加有效的进行网络安全管理,通常会部署本地网络或私有网络;本地网络和私有网络也称为NPN。
在一种场景中,如图1所示,一个NPN可以为另一个网络服务;其中,另一个网络可以为SP,SP也可以为一单独实体(separate entity);另一个网络也可以是PLMN网络;另一个网络还可以是第三方签约或证书提供实体。在该场景下,终端设备能够发现SP,并与SP连接以进行通信。
在另一种场景中,如图2所示,一个NPN可以与两个或两个以上的SP连接,为UE提供多方服务。在该场景下,UE能够发现一个NPN对应的 多个SP,需要在多个SP中选择一个SP。
在又一种场景中,如图3所示,有两个或两个以上的NPN可以用于UE驻留,两个或两个以上的NPN可以连接到不同的SP;UE需要发现这些NPN以及NPN对应的SP,UE还需要在多个NPN中选择一个NPN驻留,并在多个SP中选择一个SP。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性和复杂性,3GPP国际标准组织开始研发5G。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 Low Latency Communications,URLLC)、和大规模机器类通信(Massive Machine Type 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。另一方面,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。
在新无线(New Radio,NR)的早期部署中,完整的NR网络覆盖很难获取,所以典型的网络覆盖模式是广域的长期演进(Long Term Evolution,LTE)覆盖和NR的孤岛覆盖模式。而且用于LTE的频谱多部署在6GHz以下,可用于NR的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用;然而,高频段的覆盖范围有限、信号衰落快;同时为了保护移动运营商前期在LTE的投资,提出了LTE和NR之间紧密互通(tight interworking)的工作模式。当然,NR也可以独立部署。
本申请提供一种网络选择方法,本申请实施例的网络选择方法可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、LTE系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统或5G系统等。
示例性的,本申请实施例应用的通信系统100,如图4所示。该通信系统100可以包括网络设备110,网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110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进行通信。可选地,该网络设备110可以是GSM系统或CDMA系统中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备可以为移动交换中心、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、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。
该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于经由有线线路连接,如经由公共交换电话网络(Public Switched Telephone Networks,PSTN)、数字用户线路(Digital Subscriber Line,DSL)、数字电缆、直接电缆连接;和/或另一数据连接/网络;和/或经由无线接口,如,针对蜂窝网络、无线局域网(Wireless Local Area Network,WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器;和/或另一终端设备的被设置成接收/发送通信信号的装置;和/或物联网(Internet of Things,IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话;可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System,PCS)终端;可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System,GPS)接收器的PDA;以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、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的PLMN中的终端设备等。
可选地,终端设备120之间可以进行终端直连(Device to Device,D2D)通信。
可选地,5G系统或5G网络还可以称为NR系统或NR网络。
图4示例性地示出了一个网络设备和两个终端设备,可选地,该通信系统100可以包括多个网络设备并且每个网络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。
可选地,该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体,本申请实施例对此不作限定。

下面针对不同的场景对本申请实施例提供的网络选择方法的处理过程进行说明。
场景一,如图1所示,存在一个终端设备可以驻留的NPN,该NPN对应一个SP或对应一个Separate entity。
在图1所示的场景中,为了让终端设备能够发现该NPN提供的SP或Separate entity,NPN的网络设备需要通知终端设备SP的信息或Separateentity的信息。在具体实施时,NPN的网络设备至少可以通过下述三种方式中的一种通知终端设备SP的信息或Separate entity的信息:
方式1,NPN的网络设备通过系统广播消息通知终端设备SP的信息或Separate entity的信息。举例来说,NPN的网络设备在小区广播的系统消息 中,携带针对本小区的SP的信息或Separate entity的信息。如本小区能够支持的NPN的标识为NID(NPN Identifier),则在系统广播消息中通知携带针对此NID的SP的信息或Separate entity的信息。
方式2,NPN的网络设备通过NAS信令通知终端设备SP的信息或Separate entity的信息。举例来说,终端设备向NPN发起注册过程,NPN的网络设备在终端注册接受消息中将SP的信息或Separate entity的信息提供给终端设备。或者,终端设备向NPN发起配置更新过程,NPN的网络设备在终端配置更新消息中将SP的信息或Separate entity的信息提供给终端设备。其中,SP的信息或Separate entity的信息可以是用SID表示的SP的标识或Separate entity的标识、或SP可读名字信息、或Separate entity可读名字信息。
方式3,通过签约信息通知终端设备SP的信息或Separate entity的信息。其中,所述签约信息可以由NPN的网络设备发送至终端设备,所述签约信息也可以由SP或Separate entity发送至终端设备。在所述签约信息由NPN的网络设备发送至终端设备的情况下,所述签约信息中携带该NPN能够支持的SP的信息或Separate entity的信息。在所述签约信息由SP或Separate entity发送至终端设备的情况下,所述签约信息中携带能够为SP或Separate entity提供服务的NPN的信息。
上述三种方式中涉及的SP的信息或Separate entity的信息,可以是用SID表示的SP的标识或Separate entity的标识、或SP可读名字信息、或Separate entity可读名字信息。其中,SID可以是全球统一管理的标识,该SID在全球内唯一;在这种情况下,SID至少包括下述中的一项或多项:国家或地区代码、行业代码、以及国家或地区分配的服务商代码。SID也可以是SP或Separate entity在此NPN中的管理的标识,在此NPN中唯一;在这种情况下,SID至少包括与SP或Separate entity对应的NID。
场景二,如图2所示,存在终端设备可以驻留的一个NPN,该NPN对应SP或Separate entity的数量为两个或两个以上。
在图2所示的场景中,终端设备需要发现NPN提供的SP或Separate entity,并在多个SP或Separate entity中选择一个SP或Separate entity为终端设备提供服务。在具体实施时,可通过与场景一相同的三种方式让终端设备发现该NPN对应的SP或Separate entity。在终端设备的接入层(Access Layer,AS)实体接收到携带SP或Separate entity的信息的系统广播消息或NAS信令或签约信息的情况下,AS层实体将接收到的消息转发至NAS层 实体,NAS层实体选择一个SP或Separate entity为终端设备提供服务。
在一些实施例中,NAS层实体选择一个SP或Separate entity为终端设备提供服务的过程中,可以选择预配置的SP或Separate entity为终端设备提供服务;举例来说,若预配置的Separate entity为Separate entity2,则终端设备选择Separate entity2为终端设备提供服务。也可以选择与预配置的SP或Separate entity等效的SP或Separate entity为终端设备提供服务;举例来说,举例来说,若预配置的Separate entity为Separate entity3,且Separate entity2与Separate entity3等效,则终端设备选择Separate entity2为终端设备提供服务。还可以根据终端设备使用者的选择确定一个SP或Separate entity为终端设备提供服务。举例来说,终端设备使用者选择Separate entity1,则终端设备确定Separate entity1为终端设备提供服务。
在另一些实施例中,NAS层实体还可以根据所述终端设备允许接入的SP或Separate entity,确定一个用于提供服务的SP或Separate entity。举例来说,终端设备允许接入的Separate entity为Separate entity1,则终端设备选择Separate entity1为终端设备提供服务。
场景三,如图3所示,存在终端设备可以驻留的两个或两个以上的NPN,每个NPN对应SP或Separate entity的数量为一个或一个以上。
终端设备需要发现终端设备可以驻留的NPN,以及这些NPN提供的SP或Separate entity,并在多个NPN中选择一个NPN进行驻留,在多个SP或Separate entity中选择一个SP或Separate entity为终端设备提供服务。
终端设备需要选择一个NPN进行驻留;在具体实施时,终端设备可根据终端设备允许接入的NPN,确定一个进行驻留的NPN。举例来说,终端设备允许接入的NPN为NPN1,则终端设备只能选择NPN1进行驻留。终端设备也可根据允许接入的Separate entity选择NPN。举例来说,终端设备允许接入的Separate entity为Separate entity3,而Separate entity3对应NPN2,则终端设备选择NPN2进行驻留。
终端设备还需要选择一个Separate entity。在终端设备选择NPN1的情况下,由于NPN1对应的Separate entity为Separate entity1和Separate entity2,则终端设备需要在Separate entity1和Separate entity2中选择一个为终端设备服务。终端设备选择Separate entity的处理过程与上述场景二中终端设备选择Separate entity的处理过程相同,这里不再赘述。在具体实施时,可通过与场景一相同的三种方式让终端设备发现该NPN对应的SP或Separate entity。在终端设备的AS实体接收到携带SP或Separate entity的信息的系 统广播消息或NAS信令或签约信息的情况下,AS层实体将接收到的消息转发至NAS层实体,NAS层实体选择一个SP或Separate entity为终端设备提供服务。
在一些实施例中,NAS层实体选择一个SP或Separate entity为终端设备提供服务的过程中,可以选择预配置的SP或Separate entity为终端设备提供服务;举例来说,若预配置的Separate entity为Separate entity2,则终端设备选择Separate entity2为终端设备提供服务。也可以选择与预配置的SP或Separate entity等效的SP或Separate entity为终端设备提供服务;举例来说,举例来说,若预配置的Separate entity为Separate entity3,且Separate entity2与Separate entity3等效,则终端设备选择Separate entity2为终端设备提供服务。还可以根据终端设备使用者的选择确定一个SP或Separate entity为终端设备提供服务。举例来说,终端设备使用者选择Separate entity1,则终端设备确定Separate entity1为终端设备提供服务。
在另一些实施例中,NAS层实体还可以根据所述终端设备允许接入的SP或Separate entity,确定一个用于提供服务的SP或Separate entity。举例来说,终端设备允许接入的Separate entity为Separate entity1,则终端设备选择Separate entity1为终端设备提供服务。
本申请实施例提供的应用于网络设备的网络选择方法的一种可选处理流程,如图6所示,包括以下步骤:
步骤S301,网络设备向终端设备发送系统广播消息、或非接入层信令、或签约信息;所述统广播消息、或非接入层信令、或签约信息,用于所述终端设备确定至少一个服务提供商的信息,所述服务提供商的信息用于所述终端设备确定一个用于驻留的非公共网络和/或一个用于提供服务的服务提供商。
