图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中,终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、增强现实(augmented reality,AR)/虚拟现实(virtual reality,VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(Vehicle  User Equipment,VUE)、行人终端(Pedestrian User Equipment,PUE)、智能家居(具有无线通信功能的家居设备,如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer,PC)、柜员机或者自助机等终端侧设备,可穿戴式设备包括:智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备,其中,接入网设备也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备可以包括基站、无线局域网(Wireless Local Area Network,WLAN)接入点或WiFi节点等,基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例进行介绍,并不限定基站的具体类型。核心网设备可以包含但不限于如下至少一项:核心网节点、核心网功能、移动管理实体(Mobility Management Entity,MME)、接入移动管理功能(Access and Mobility Management Function,AMF)、会话管理功能(Session Management Function,SMF)、用户平面功能(User Plane Function,UPF)、策略控制功能(Policy Control Function,PCF)、策略与计费规则功能单元(Policy and Charging Rules Function,PCRF)、边缘应用服务发现功能(Edge Application Server Discovery Function,EASDF)、统一数据管理(Unified Data Management,UDM),统一数据仓储(Unified Data Repository,UDR)、归属用户服务器(Home Subscriber Server,HSS)、集中式网络配置(Centralized network configuration,CNC)、网络存储功能(Network Repository Function,NRF),网络开放功能(Network Exposure Function,NEF)、本地NEF(Local NEF,或L-NEF)、绑定支持功能(Binding Support Function,BSF)、应用功能(Application Function,AF)等。需要说明的是,在本申请实施例中仅以NR系统中的核心网设备为例进行介绍,并不限定核心网设备的具体类型。
为了方便理解,以下对本申请实施例涉及的一些内容进行说明:
一、终端通过underlay网络接入overlay网络。
如图2所示,终端通过underlay网络接入overlay网络包括以下流程:
1、终端通过公共陆地移动网(Public Land Mobile Network,PLMN)的Uu口注册到PLMN;
2、当终端要到独立非公共网络(Stand-alone Non-Public Network,SNPN)获取业务时,终端建立到SNPN对应的非3GPP交互功能(Non-3GPP InterWorking Function,N3IWF)的数据连接;
3、终端通过上述数据连接发送注册消息给SNPN核心网(Core Network,CN),此时 终端使用的是PLMN签约;
4、终端在SNPN CN注册完成以后,在SNPN获取服务。
由于目前对于终端如何选择underlay网络没有明确,为此提出本申请的选网处理方法。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的选网处理方法进行详细地说明。
参照图3,本申请实施例提供了一种选网处理方法,如图3所示,该选网处理方法包括:
步骤301,终端获取底层网络和上层网络的对应关系;
步骤302,所述终端根据所述对应关系接入第一上层网络或者执行网络重选过程;
其中,所述对应关系包括以下至少一项:
第一信息,所述第一信息包括至少一个第一网络列表以及每一所述第一网络列表对应的一个上层网络,所述第一网络列表包括至少一个底层网络;
第二信息,所述第二信息包括至少一个第二网络列表以及每一所述第二网络列表对应的一个底层网络,所述第二网络列表包括可通过所述底层网络接入的至少一个上层网络;
第三信息,所述第三信息包括至少一个底层网络列表和每一底层网络列表对应的上层网络列表,所述底层网络列表包括至少一个底层网络,上层网络列表包括至少一个上层网络,且上层网络列表中的每一上层网络均可通过底层网络列表中任一底层网络接入。
本申请实施例中,针对上述第一信息可以理解为包括每一上层网络和所述上层网络允许被接入的底层网络的对应关系,也就是说,第一信息包括某个overlay网络对应的underlay网络列表。针对上述第二信息可以理解为包括每一底层网络和底层网络可接入的网络的对应关系,也就是说,第二信息包括通过某个underlay网络可以接入的overlay网络列表。针对上述第三信息,当上层网络列表包括至少两个上层网络,且底层网络列表包括至少两个底层网络时,第三信息可以理解为包括至少两个underlay网络与至少两个overlay网络的对应关系。
上述第一上层网络可以理解为需要接入的目标网络。其中,上述底层网络可以包括SNPN和/或PLMN,上述上层网络也可以包括SNPN和/或PLMN。
例如,当终端通过NWu(UE和N3IWF之间的参考点)使用建立在PLMN上的用户面接入SNPN服务,PLMN是underlay网络,SNPN是overlay网络。当终端通过NWu使用建立在SNPN上的用户面接入PLMN服务,PLMN是underlay网络,SNPN是overlay网络。
可选地,所述终端根据所述对应关系接入第一上层网络可以理解为第二网络属于第一上层网络对应的第一底层网络,所述终端基于第二网络作为底层网络接入第一上层网络,该第二网络为终端当前接入的网络,其中,终端可以直接接入第二网络,也可以通过某一底层网络接入上述第二网络。也就是说,终端可以直接通过第二网络向第一上层网络发送注册消息,从而注册到第一上层网络中,以获取第一上层网络的业务,这样无需基于随机 接入过程进行网络切换,因此可以提高注册到第一上层网络的可靠性,进而提高了从第一上层网络获取业务的可靠性。
上述终端根据所述对应关系执行网络重选过程可以理解为第二网络不属于第一上层网络对应的第一底层网络,从而基于所述对应关系确定第一上层网络对应的底层网络,以实现网络重选。在进行网络重选后,可以重新接入重选的底层网络,并基于重选的底层网络接入到第一上层网络。
本申请实施例中,通过获取底层网络和上层网络的对应关系,从而可以基于对应关系选择底层网络,进而基于选择的底层网络接入相应的上层网络,以使终端能够同时使用两个不同网络的服务。与此同时,当终端当前直接的第二网络属于第一上层网络对应的第一底层网络时,可以指直接基于第二网络作为底层网络接入第一上层网络,提高了终端从第一上层网络获取业务的时效性和可靠性。
可选地,在一些实施例中,所述终端根据所述对应关系接入第一上层网络或者执行网络重选过程包括:
所述终端根据所述对应关系确定第二网络是否属于所述第一上层网络对应的第一底层网络,所述第二网络为当前接入的网络;
在所述第二网络属于所述第一底层网络的情况下,所述终端以所述第二网络作为底层网络接入所述第一上层网络;
在所述第二网络不属于所述第一底层网络的情况下,所述终端基于所述第一底层网络执行网络重选过程。
本申请实施例中,上述第一上层网络的数量可以为一个,即根据一个第一上层网络和对应关系选择底层网络。在所述第二网络属于所述第一底层网络的情况下,可以理解为可以通过所述第二网络作为底层网络接入所述第一上层网络,此时可以将第二网络作为底层网络。在所述第二网络不属于所述第一底层网络的情况下,则需要基于第一底层网络重选选择底层网络,这样可以基于重新选择的底层网络接入第一上层网络。
需要说明的是,针对对应关系包括内容的不同,确定第二网络是否属于所述第一上层网络对应的第一底层网络的方式不同,例如,在一些实施例中,所述终端根据所述对应关系确定第二网络是否属于所述第一上层网络对应的第一底层网络包括:
在所述对应关系包括所述第一信息的情况下,所述终端基于所述第二网络是否包含在所述第一网络列表中,确定所述第二网络是否属于所述第一上层网络对应的第一底层网络;
在所述对应关系包括所述第二信息的情况下,所述终端基于所述第一上层网络是否包含在所述第二网络作为底层网络所对应的第二网络列表中,确定所述第二网络是否属于所述第一上层网络对应的第一底层网络;
在所述对应关系包括所述第三信息的情况下,所述终端基于所述第二网络是否包含在所述第一上层网络对应的所述底层网络列表中,确定所述第二网络是否属于所述第一上层网络对应的第一底层网络。
本申请实施例中,针对上述第一信息,当所述第二网络包含则第一网络列表中,则可以确定所述第二网络属于所述第一上层网络对应的第一底层网络,否则确定所述第二网络不属于所述第一上层网络对应的第一底层网络。
针对上述第二信息,当所述第一上层网络包含在所述第二网络作为底层网络所对应的第二网络列表中,则可以确定所述第二网络属于所述第一上层网络对应的第一底层网络,否则确定所述第二网络不属于所述第一上层网络对应的第一底层网络。
针对上述第三信息,当所述第二网络包含在所述第一上层网络对应的所述底层网络列表中,则可以确定所述第二网络属于所述第一上层网络对应的第一底层网络,否则确定所述第二网络不属于所述第一上层网络对应的第一底层网络。
可选地,在一些实施例中,所述终端基于所述第一底层网络执行网络重选过程包括:
所述终端基于偏好接入模式(prefer access mode)和所述第一底层网络执行网络重选过程。
本申请实施例中,上述偏好接入模式可以由协议约定、用户设置或者网络侧设备指示,在此不做进一步的限定。
可选地,在一些实施例中,当终端选择至少两个overlay网络进行接入的情况下,基于可以同时接入两个overlay网络的underlay网络列表选择underlay网络。例如,在一些实施例中,在所述第一上层网络的数量为至少两个的情况下,所述终端根据所述对应关系接入第一上层网络或者执行网络重选过程包括:
所述终端针对每一所述第一上层网络,确定所述第一上层网络对应的至少一个底层网络,所述至少一个底层网络可用于所述第一上层网络;
所述终端基于每一所述第一上层网络对应的所述至少一个底层网络确定第三网络列表,所述第三网络列表包括每一所述第一上层网络对应的所述至少一个底层网络中可同时用于每一所述第一上层网络的底层网络;
在第二网络属于所述第三网络列表的情况下,所述终端以所述第二网络作为底层网络接入每一所述第一上层网络,所述的第二网络为当前接入的网络;
在所述第二网络不属于第三网络列表的情况下,所述终端基于所述第三网络列表执行网络重选过程。
