Description

一种通信方法、装置及系统
本申请要求于2019年01月31日提交中国国家知识产权局、申请号为201910098742.5、申请名称为“一种通信方法、装置及系统”的中国专利申请，以及于2019年09月30日提交中国国家知识产权局、申请号为201910937699.7、申请名称为“一种通信方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法、装置及系统。
背景技术
目前，通信发展中提出了私网的概念，私网是相对于公网的一个概念，可以理解为私密的网络，例如公司、学校或者工厂搭建的内部网络。未与私网签约的用户设备(user equipment，UE)不允许接入私网。私网也称之为non-public network，即NPN，一般可以通过私网标识(NPN identification，NPN ID)来识别私网类型，不同的UE支持不同的NPN ID，UE仅可以在其支持的NPN ID对应的NPN驻留，并仅可以在其签约的NPN ID对应的NPN发起业务。
目前，私网的部署方式有如下几种：
1、私网可以为配置私网专有的基站、核心网下的小区，支持该私网的UE可以在基站、核心网驻留和发起业务，标准一般称这种私网为独立(standalone，SA)NPN小区。
2、私网也可以为公网的一个切片(slice)，即可以将公网中的一个切片配置为私网，所有UE都可以在该网络驻留，等UE进入连接态发起业务请求后，网络再根据业务是否是私网业务，把UE的业务制定到对应的私网slice上。
3、私网还可以是公网运营商部署的一个小区。标准一般称这种私网为封闭访问组(closed access group，CAG)小区，或者非独立(non-standalone，NSA)NPN小区。
4、私网业务不仅可以在上述3种部署的网络中传输，还可以通过与私网有非3GPP互操作功能(non-3GPP inter working function，N3IWF)接口的公网进行传输。即公网本身的资源上并不支持直接的私网业务，私网业务可以在公网中透明传输。当私网数据到达公网的数据网络(data network，DN)后，再通过N3IWF接口发送到私网。
引入私网后，需要考虑支持私网的UE在上述4种网络之间的移动性机制。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
目前，通信发展中提出了私网的概念，私网是相对于公网的一个概念，可以理解为私密的网络，例如公司、学校或者工厂搭建的内部网络。未与私网签约的用户设备(user equipment，UE)不允许接入私网。私网也称之为non-public network，即NPN，一般可以通过私网标识(NPN identification，NPN ID)来识别私网类型，不同的UE支持不同的NPN ID，UE仅可以在其支持的NPN ID对应的NPN驻留，并仅可以在其签约的NPN ID对应的NPN发起业务。
目前，私网的部署方式有如下几种：
1、私网可以为配置私网专有的基站、核心网下的小区，支持该私网的UE可以在基站、核心网驻留和发起业务，标准一般称这种私网为独立(standalone，SA)NPN小区。一种可能的部署方式如图1A所示。
2、私网也可以为公网的一个切片(slice)，即可以将公网中的一个切片配置为私网，所有UE都可以在该网络驻留，等UE进入连接态发起业务请求后，网络再根据业务是否是私网业务，把UE的业务制定到对应的私网slice上。
3、私网还可以是公网运营商部署的一个小区。标准一般称这种私网为封闭访问组(closed access group，CAG)小区，或者非独立(non-standalone，NSA)NPN小区。一种可能的部署方式如图1B所示。
4、私网业务不仅可以在上述3种部署的网络中传输，还可以通过与私网有非3GPP互操作功能(non-3GPP inter working function，N3IWF)接口的公网进行传输。即公网本身的资源上并不支持直接的私网业务，私网业务可以在公网中透明传输再通过N3IWF接口发送到私网。一种可能的部署方式如图1C所示，当私网数据到达公网的数据网络(data network，DN)后，再通过N3IWF接口发送到私网。
可选的，方式1ˉ3对应的网络设备可以在空口直接支持私网业务，因此可以称为直接支持。方式4中空口不支持私网业务，而需要在公网中通过N3IWF的方式支持私网业务，因此该传输方式也可以成为间接支持。
可以理解的，方式4以公网通过N3IWF支持私网业务为例进行说明，还存在私网通过N3IWF支持公网业务的情况。
示例性的，图1C示出了一种公网通过N3IWF接口支持私网业务的架构图，其中，公网可以包括公共陆地移动网络(publ ic land mobi lenetwork，PLMN)第三代合作伙伴计划(the 3rd generat ion partnership project，3GPP)访问(PLMN 3GPP access)节点、接入网设备、用户面功能实体(user plane function，UPF)、接入与移动性管理实体(access and mobility management function，AMF)、会话管理功能实体(session management function，SMF)、DN等等。私网可以包括私网对应的接入网设备、UPF、AMF、SMF、DN等等。公网和私网之间可以通过N3IWF进行通信。其中，公网的PLMN PLMN access与公网的UPF通过N3接口相连，UE与公网的AMF通过N1接口相连，公网的PLMN PLMN access与公网的AMF通过N2接口相连，公网的AMF与公网的SMF通过N11相连，公网的SMF与公网的UPF通过N4接口相连，公网的UPF与公网的DN相连，公网的DN与N3IWF相连。N3IWF与私网的UPF通过N3接口相连，N3IWF与私网的AMF通过N2接口相连，私网的UPF与私网的AMF通过N4接口相连，私网的AMF与私网的SMF通过N11接口相连。
引入私网之后，可以简单的将UE分为三类：私网UE，即仅与私网签约的UE，例如工 厂内智能手机的智能终端等等；同时支持私网和公网的UE，比如私网接入人员的手机；公网UE，仅与公网签约的UE，这种UE完全不适用于私网。对于上述三类UE，前述两种均可适用于私网，第三种则为不适用于私网的UE。
本申请实施例提供的通信方法可以应用于通信系统中。该通信系统的架构可以如图2所示，包括第一接入网设备、第二接入网设备、核心网设备及终端设备。本申请实施例涉及的通信系统可以是各类通信系统，例如，可以是长期演进(long term evolut ion，LTE)，也可以是第五代(5G)通信系统，还可以是LTE与5G混合架构，还可以是未来的通信系统。本申请实施例涉及的通信系统中接入网设备与终端设备之间可以但不限于通过无线电波、可见光、激光、红外、光量子、电力线、光纤、同轴电缆、铜绞线等方式进行数据传输。
本申请实施例中所涉及通信系统中可以部署私网，其中，私网的部署方式可以但不限于通过图1A至图1C任一所述的部署方式。
其中，第一接入网设备、第二接入网设备，可以是普通的基站(如Node B或eNB)，可以是新无线控制器(new radio controller，NR controller)，可以是5G系统中的gNode B(gNB)，可以是集中式网元(centralized unit，CU)，可以是新无线基站，可以是射频拉远模块，可以是微基站，可以是中继(relay)，可以是分布式网元(distributed unit，DU)，可以是接收点(transmission reception point，TRP)或传输点(transmission point，TP)或者任何其它无线接入设备，但本申请实施例不限于此。
核心网设备，可以是移动管理功能(access and mobility management function，AMF)。
终端设备，又称之为用户设备(user equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括：手机、平板电脑、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，例如智能手表、智能手环、计步器等。
引入私网后，需要考虑支持私网的UE在上述4种网络之间的移动性机制。因此，本申请实施例提供一种通信方法，以提供终端设备在私网之间的移动性机制。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
以下，对本申请中的部分用语进行解释说明，以便与本领域技术人员理解。
多个，是指两个或两个以上。
另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
下面结合附图对本申请提供的无线通信方法进行具体说明。
参见图3，为本申请实施例提供的通信方法的流程图。本申请提供的通信方法可以用于图2所示的通信系统。可以理解的，图2所示的通信系统架构仅为一种示例。本发明实施例提供的通信方法可以适用于各种私网部署场景下，从源接入网设备切入目标私网的场景。

本申请实施中图4、图5、图6可以单独作为一个方案实施，也可以结合实施，如图4ˉ图6中任意两个结合起来作为一个方案实施，或者，图4ˉ图6结合起来作为一个方案实施。
在通信系统中，终端设备包括无线资源控制(radio resource control，RRC)连接态(RRC_connected)、RRC空闲态(RRC_idle)、非激活态或去激活态(inactive)。inactive的终端设备可以包括如下几个特征中的至少一个：
1)终端设备进入inactive时，终端设备和配置终端设备进入inactive的接入网设备保留UE的接入层上下文信息。
为了方便描述，本申请实施例将配置终端设备进入inactive的接入网设备成为锚点(anchor)接入网设备。
2)Anchor接入网设备保持该终端设备和核心网设备的控制面和用户面连接；Anchor接入网设备为终端设备分配基于无线接入网((radio access network，RAN)的通知区域(RNA)，终端设备在RNA内仅执行周期性RNA更新(RNAU)，当终端设备移出RNA后，终端设备发送移动性触发的RNAU。
3)Anchor接入网设备为终端设备分配inactive无线网络临时标识(inactive radio network temporary identifier，I-RNTI)，I-RNTI可以用于识别anchor接入网设备以及在anchor接入网设备内唯一识别终端设备。
4)终端设备执行小区重选。
5)inactive的终端设备的非连续接收(discont inuous，DRX)可以有3种：小区系统消息广播的DRX、CN配置的DRX、anchor接入网设备为终端设备配置的RAN DRX，终端设备根据最小DRX长度监听寻呼消息。
inactive的终端设备的anchor接入网设备和核心网设备的控制面和用户面连接都保持，因此当终端设备的下行数据到达时，核心网设备直接把数据发送给anchor接入网设备，此时anchor接入网设备需要在整个RNA内寻呼终端设备，因此需要引入RAN-based paging，用于实现接入网设备触发的寻呼功能。RNA内的接入网设备在空口发送寻呼消息寻呼终端设备，此时只需要携带anchor接入网设备为UE分配的I-RNTI。
当终端设备在其他接入网设备响应寻呼或发起接入时，终端设备向其他接入网设备发送I-RNTI，其他接入网设备可以根据I-RNTI识别anchor接入网设备，并获取终端设备在anchor接入网设备的上下文信息。从而其他接入网设备可以在发送msg4时配置终端设备进入连接态，可以大大缩短终端设备进入连接态的时延，节省了空口信令开销。
在第一网络场景下，也可以考虑引入inactive态，可以进一步节省UE能耗同时支持快速状态转换。基于此，本申请实施例提供一种通信方法，以提供inactive相关的配置 信息的适应性修改以支持第一网络场景。参见图7，为本申请实施例提供的通信方法的流程图。本申请提供的通信方法可以用于图2所示的通信系统。本发明实施例提供的通信方法可以适用于各种私网部署场景下，从源接入网设备切入目标私网的场景。
本申请实施例提供的通信方法具体可以如下：
S701，第一接入网设备获得终端设备签约的第一网络的标识。
第一接入网设备获取终端设备签约的第一网络的标识的方式可以是从核心网设备获取的，也可以是从终端设备获取的，还可以是从其它接入网设备获取的，本实施例对此不作限定。可选的，具体的获取方式可以参考本申请其它实施例的描述。
S702，第一接入网设备向终端设备发送包括至少一个NPN ID的RNA配置。
第一接入网设备配置终端设备进入inactive时，第一接入网设备发送包括至少一个NPN ID的RNA配置，用于指示终端设备第一网络的通知区域。
可选的，第一接入网设备还可以向第二接入网设备发送RAN paging，该RAN paging消息中携带至少一个NPN ID，用指示第二接入网设备仅需在上述NPN ID对应的小区内寻呼终端设备。
第二接入网设备可以为终端设备的RNA配置中的任一接入网设备。
比如当该终端设备的下行数据或信令到达第一接入网设备时，第一接入网设备可以向RNA内的其它接入网设备发起RAN paging，RAN paging中携带至少一个NPN ID。
此外，第一接入网设备还可以向第三接入网设备发送终端设备上下文信息，该终端上下文信息中包括第一接入网设备为终端设备配置的包括至少一个NPN ID的RNA配置。
第三接入网设备可以为终端设备的RNA配置中的任一接入网设备。可以理解的，第二接入网设备和第三接入网设备可以是同一个接入网设备，也可以是不同的接入网设备。
比如当该终端设备向不同于第一接入网设备的新接入网设备发起接入请求，该新接入网设备可以向第一接入网设备发送请求消息，该请求消息用于请求终端设备的上下文信息；若第一接入网设备确定转发该终端设备的上下文信息，第一接入网设备向该新接入网设备发送终端设备的上下文信息，该终端设备的上下文信息中包括第一接入网设备为终端设备配置的包括至少一个NPN ID的RNA配置。
