Description

一种网络接入的方法和装置

技术领域
本申请涉及无线通信技术领域，特别涉及一种网络接入的方法和装置。
背景技术
非公网络(non-public networks,NPN)是3GPP标准中正在讨论的一种网络，区别于公共陆地移动网络(public land mobile networks,PLMN)，NPN网络只允许某些具有特定权限的用户接入。NPN网络分为独立(standalone)组网和非独立(non-standalone)组网两种组网方式，其中，在NPN独立组网中，NPN网络和PLMN网络拥有独立的接入网(radio access network,RAN)和核心网(core network,CN)，二者的核心网之间通过N3IWF网元相连接。而在NPN非独立组网中，NPN网络和PLMN网络的接入网设备共用核心网，部分处于PLMN网络中的接入网设备可以接入到NPN网络中，配置有NPN小区，允许NPN终端接入，部分处于NPN网络中的接入网设备可以接入到PLMN网络中，配置有PLMN小区，允许PLMN终端接入。
对于NPN非独立组网，处于某一网络(PLMN或者NPN网络)内的接入网设备可能并不知晓其他的接入网设备对另一网络的接入能力，同样的，核心网设备也并不知晓处于某一网络内的接入网设备对另一网络的接入能力，由此使得网络设备(包括接入网设备和核心网设备)在进行用户设备的接入控制、小区测量参数配置、PDU会话资源的建立、用户寻呼等操作具有盲目性，导致操作效率不高。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
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)、第五代(5th generation，5G)系统或新无线(new radio，NR)或者其他演进的通信系统等。
本申请实施例中的终端设备也可以称为：终端、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)、接入终端、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等。
终端设备可以是一种向用户提供语音/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。目前，一些终端的举例为：手机(mobile phone)、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，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、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、个人数字助理(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公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，在本申请实施例中，终端设备还可以是物联网(internet of things，IoT)系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。
另外，本申请实施例中的接入网设备可以为特定区域的授权用户提供入网功能，并能够根据用户级别、业务需求等使用不同质量的传输隧道。接入网络可以为采用不同接入技术的接入网络。目前的无线接入技术包括：第三代合作伙伴计划(3 rd generation partnership project，3GPP)接入技术和非第三代合作伙伴计划(non-3GPP)接入技术。3GPP接入技术是指符合3GPP标准规范的接入技术。例如包括第三代(3 rd generation，3G)系统、第四代(4 th generation，4G)系统、5G系统中采用的无线接入技术。采用3GPP接入技术的接入网络称为无线接入网络(radio access network，RAN)。其中，5G系统中的接入网设备称为下一代基站节点(next generation node base station，gNB)。非3GPP接入技术是指不符合3GPP标准规范的接入技术。例如，以无线保真(wireless fidelity，WiFi)为代表的空口技术。
基于无线通信技术实现接入网络功能的接入网可以称为接入网。无线接入网能够管理无线资源，为终端设备提供接入服务，进而完成控制信号和用户数据在终端设备和核心网之间的转发。
本申请实施例中的接入网设备也可以被称为无线接入网设备或者基站等，可以是传输接收点(transmission reception point，TRP)，也可以是全球移动通信(global system for mobile  communications，GSM)系统或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(evolved NodeB，eNB或eNodeB)，还可以是基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该接入网设备可以为中继站、接入点、车载设备、可穿戴设备以及5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，可以是WLAN中的接入点(access point，AP),可以是新型无线系统(new radio，NR)系统中的新空口节点(new radio nodeB,gNB)，本申请实施例并不限定。
在一种网络结构中，接入网设备可以包括集中单元(central unit，CU)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点的RAN设备、或者控制面CU节点(CU-CP节点)和用户面CU节点(CU-UP节点)以及DU节点的RAN设备。
接入网设备通过小区或者小区中的收发点为终端设备提供服务，终端设备通过接入网设备分配的传输资源(例如，频域资源，或者说，频谱资源，或者说，视频资源)与小区或者小区中的收发点进行通信，该小区可以是收发点对应的小区，小区可以属于宏基站(例如，宏eNB或宏gNB等)，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(metro cell)、微小区(micro cell)、微微小区(pico cell)、毫微微小区(femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
本申请实施例中的核心网设备可以用于实现呼叫的接续、计费、移动性管理以及补充业务等功能。在5G系统中，核心网设备例如可以包括接入和移动管理功能(access and mobility management function，AMF)实体、会话管理功能(session management function，SMF)实体以及用户平面功能(user plane function，UPF)实体等。本申请实施例主要涉及与AMF实体通信。因此，这里对AMF实体做简单说明。AMF实体也可以简称AMF，主要用于移动性管理和接入管理等，可用于实现移动性管理实体(mobility management entity，MME)功能中除会话管理之外的其他功能。例如，合法监听、接入授权(或鉴权)等功能。下文中将5G中的AMF作为用于移动性和接入管理的网元的一例，不应对本申请构成任何限定。本申请并不排除用其他网元替代AMF实现相同或相似功能的可能。
其中，接入网设备和核心网设备在下文实施例中可以统称为网络设备。
为了帮助理解本申请实施例的技术方案，下面对5G网络中的基站gNB进行说明。
图1示出了5G网络中gNB的整体架构。如图1所示，针对5G网络中的gNB定义了一种新的架构(CU-DU架构)，即根据协议栈功能将gNB分为两部分：集中单元和分布单元。
上述CU-DU架构具有如下特性：
1)CU包括协议栈实体RRC、SDAP、PDCP；DU包含协议栈实体RLC、MAC和PHY。
2)一个gNB可以包括一个CU和至少一个DU，CU和DU之间采用F1接口进行连接。
3)CU与其他gNB之间采用Xn接口连接。
4)CU与5G的核心网(5G core,5GC)之间采用NG接口连接。
此外，在具体实现的过程中，考虑到系统的稳定性，一个DU可以与多个CU相连接。
进一步地，对于CU的结构还可以做进一步地细分。图2示出了5G分离式基站网元间连接示意图。
参见图2，可以将gNB-CU进一步分为一个gNB-CU-CP和至少一个gNB-CU-UP，分别用于控制面管理和用户面数据传输，gNB-CU-CP与gNB-CU-UP之间的接口为E1口。gNB-CU-CP与gNB-DU之间的接口为F1-C口，用于控制面信令的传输；gNB-CU-UP与gNB-DU之间的接口为F1-U口，用于用户面数据传输。gNB-CU-UP与gNB-CU-UP之间通过Xn-U口进行连接，只能进行用户面数据传输。
下面结合附图继续对NPN网络进行介绍。
NPN网络是3GPP标准中正在讨论的一种网络，区别于传统蜂窝网络，NPN网络只允许某些具有特定权限的用户接入。NPN网络分为独立组网和非独立组网两种组网方式。非独立组网中，将有特殊权限接入NPN网络的用户称为封闭访问组(Closed Access Group，CAG)。
图3示出了NPN独立组网的结构示意图。如图3所示，NPN独立组网中，NPN网络和PLMN网络拥有独立的RAN和CN，CN之间通过N3IWF网元相连，通过N3IWF网元可进行用户面数据的传输，但不能进行控制信令的传输。
图4示出了NPN非独立网组的结构示意图。如图4所示，NPN非独立组网中，NPN和PLMN共用核心网；PLMN CU可以被PLMN和NPN网络共用，其可同时连接PLMN DU和NPN DU；DU也可被PLMN网络和NPN网络共用(Shared)；同时，也会存在只用于PLMN网络或者NPN网络的CU和DU。在图4中，由于NPN网络以非独立组网的形式存在，因此，前述的NPN DU、NPN CU也可以被称为CAG DU、CAG CU，而CAG DU下的小区可以被称为CAG小区。
图5是能够适用本申请实施例切换方法的系统100的示意图。
在图5中，核心网网元AMF通过NG接口与CU相连接，CU通过F1接口分别与两个不同的DU(NPN DU和PLMN DU)相连接，UE与NPN DU相连接，随着UE不断向图中右侧移动，将面临小区切换的问题，因为CU可能并不知晓PLMN DU是否能够接入NPN网络，因此，CU给UE配置的测量参数可能并不合理。例如，CU给UE配置的测量目标可能包括该PLMN DU下的一个小区，然后该小区有可能无法接入NPN网络中，即使之后UE连接入该小区，也无法接入NPN网络中，由此降低了接入操作的效率。
此外，AMF也可能并不知晓PLMN DU是否能够接入NPN网络，AMF可能在PLMN DU上建立NPN的协议数据单元(protocol data unit,PDU)会话，如果PLMN DU不具备接入NPN网络的能力，则此时PDU会话的建立是无效和浪费的，并不能支持用户数据在相应PDU会话资源中进行传输。
AMF还可能会因为来自PLMN的PDU会话使只支持NPN的NPN DU寻呼UE，或者AMF可能会因为来自NPN的PDU会话使只支持PLMN的PLMN DU寻呼UE，这些情况下，寻呼是无效和浪费的。
基于上述分析，本申请提供一种网络接入的方法，能够提高网络设备进行用户设备的接入控制、小区测量参数配置、PDU会话资源的建立、用户寻呼等操作的效率。
下面介绍本申请实施例提供的方法，作为示例而非限定，下文中第一网络设备可以是图5中的PLMN DU，第二网络设备可以是图5中的CU，或者，第一网络设备可以是图5中的CU，第二网络设备可以是图5中的AMF。
图6是本申请的网络接入的方法200的示意性流程图。以下，结合图6阐述本申请实施例提供的网络接入的方法200，该方法200包括：
步骤210，第一网络设备向第二网络设备发送接入能力信息，第一网络设备是第一类型网络中的网络设备，该接入能力信息用于指示第一网络设备接入第二类型网络的能力，第一类型网络和第二类型网络不同。
具体地，接入能力信息用于指示第一网络设备接入到第二类型网络的能力，其中，第一网络设备接入到第二类型网络的能力可以是核心网设备给该第一网络设备配置的。
第一网络设备是第一类型网络中的网络设备，可以理解为第一网络设备连接于第一类型网络中。对于分布式基站，例如分布式gNB，可以是其一个或者多个DU单元中的至少一个DU单元连接于第一类型的网络中。
接入能力信息用于指示第一网络设备接入第二类型网络的能力，该能力可以包括第一网络设备是否能够接入到第二类型网络中，能够接入到哪些第二类型网络中，能够配置哪些第二类型网络的小区，或者能够配置哪些第二类型网络的切片中等。
此外，还可以以DU单元为粒度，该能力还可以包括该DU单元是否能够接入第二类型网络，能接入哪些第二类型网络，配置哪些第二类型网络的小区或切片等等。

此外，第一网络设备下通常包括有一个或者多个服务小区，接入能力信息也可以用于指示该一个或者多个服务小区中的至少一个小区的接入能力。
具体地，可以以小区为粒度，指示至少一个小区接入第二类型网络的能力，从而能够给终端设备合理的配置测量参数，例如，可以将能够接入第二网络类型的小区配置为终端设备的测量目标，终端设备可以通过接入该小区从而最终接入到第二类型网络中，提高了终端设备的测量和接入的效率。
例如，接入能力信息可以指示第一网络设备下的至少一个小区能够接入到的第二类型网络的网络列表、配置的第二类型网络的小区列表、配置的第二类型网络的切片列表中的至少一种。
此外，一个服务小区可能包括多个切片，或者说，第一网络设备下可能包括有一个或者多个切片，该接入能力信息也可以用于指示该一个或者多个切片中的至少一个切片的接入能力。
例如，接入能力信息可以指示第一网络设备下的至少一个切片能够接入到的第二类型网络的网络列表、配置的第二类型网络的小区列表、配置的第二类型网络的切片列表中的至少一种。
第一类型网络和第二类型网络不同，作为示例，该第一类型网络可以是PLMN网络， 第二类型网络为NPN网络。或者，第一类型网络为NPN网络，第二类型网络为PLMN网络。此外，本申请对第一类型网络以及第二类型网络的具体类型并不做限定。
本申请对第二网络设备所处网络的网络类型并不做限定。该第二网络设备可以处于第一网络类型中，也可以处于第二网络类型中，也可以处于第一网络类型和第二网络类型之外的网络类型中。
第一网络设备和第二网络设备为两个不同的设备，以下对第一网络设备和第二网络设备的类型做举例说明。
在一种可能的实现方式中，第一网络设备为DU单元，第二网络设备为CU单元。此外，第一网络设备也可以为CU单元，第二网络设备为DU单元。
在另一种可能的实现方式中，第一网络设备为CU-UP单元，第二网络设备为CU-CP单元。此外，第一网络设备也可以为CU-CP单元，第二网络设备为CU-UP单元。
在另一种可能的实现方式中，第一网络设备和第二网络设备均为接入网设备(例如基站，gNB)。
在另一种可能的实现方式中，第一网络设备为接入网设备(例如基站，gNB)，第二网络设备为核心网设备(例如AMF)。此外，第一网络设备也可以为核心网设备，第一网络设备为接入网设备。
本实施例提供的网络接入的方法，能够将处于第一类型网络中的第一网络设备对第二类型网络的接入能力信息发送给第二网络设备，第二网络设备获取该接入能力信息，能够根据该接入能力信息进行用户设备的接入控制、小区测量参数配置、PDU会话资源的建立、用户寻呼等操作，从而使得对上述各种操作更有针对性，提高上述各种操作的效率。
下面根据对第一网络设备、第二网络设备、第一类型网络、第二类型网络选择的不同，通过多个实施例来阐述本申请提供的接入方法。
图7是本申请的网络接入的方法300的示意性流程图。在图7所示的实施例中，第一网络设备为DU单元，第二网络设备为CU单元，第一类型网络为PLMN网络，第二类型网络为NPN网络。
应理解，上述限定仅是为了便于说明本申请实施例提供的技术方案，以及方便理解，在其他可能的实现方式中，第一网络设备也可以为CU单元，第二网络设备为DU单元。此外，第一类型网络也可以为NPN网络，而第二类型网络为PLMN网络。
以下，结合图7阐述本申请实施例提供的网络接入的方法300，该方法300包括：
步骤310，DU单元向CU单元发送接入能力信息，DU单元位于PLMN网络中，该接入能力信息用于指示DU单元接入NPN网络的能力。
